ond fast pulley is shifted; and as this clutch has but one tooth, the shaft is thereby permitted to make part of a revolution, during which the second series of operations takes place before it (the clutch) begins to act, and then it communicates motion to a large cog wheel provided with a crank pin, that actuates a connecting rod jointed to a rack, (below the top-sliding rack above described,) the teeth of which take into the teeth of a pinion on the shaft of one of the train of wheels that communicates motion to the carriage, thereby imparting the desired movement. The winding on of the yarn during the running in of the carriage is effected by the top sliding rack, which for this purpose is carried by the rack just described, by means of such connexions as admit of modifying the motions of the top sliding rack, which drives the spindles in winding on. Motion is communicated from the bottom to the top rack in the following manner: On the end of the lower rack, and by the side of it, there is a stud-pin on which turns a scroll cam, and to that part of its periphery which is nearest the axis is attached one end of a chain, which passes from thence around a roller that turns on a stud-pin at the side of the lower rack, and is then carried back and attached by a short arm to the top sliding rack, so that when the lower rack slides, the top rack will move with it, provided the scroll cam remains immovable on its axis; but the motion of the top rack, during each operation, must have a motion accelerated relatively to that of the lower rack, to increase the rotation of the spindles as the threads are wound round on a gradually diminishing diameter of the conical form of the cops. This is effected by causing the scroll cam to turn on its axis during the motion of the rack, by having a wheel attached to and turning with it, to the periphery of which is attached one end of a chain that passes round it, and is attached by the other end to another part of the machine, so that, if this part of the attachment remains fixed, a regular accele rated motion will be given to the top rack relatively to the motion of the lower rack, and necessarily the spindles will have their rotation. accelerated relatively to the motion of the carriage. These relative motions of the two racks, as described, are such as are required after the base of the cops has been formed, for then the threads are wound regularly on a cone; but in forming the base of the cops the first winding is on the naked spindles, at which time the motion of the spindles should correspond with that of the carriage; and from the commencement until the base is formed, the accelerated motion should be gradually brought into play to give the conical form to the cops. This is effected by having the chain that winds on the wheel that turns with the scroll cam attached to a slide that works on a screw in a vibrating arm, the outer end of which is jointed to another arm of equal length that turns on the end of the stud on which the scroll cam and wheel turn, so that when the slide is at the lower end of the arm-the two arms being of equal length-the motion of the wheel with the rack will not cause it to wind up the chain, but, as the slide is drawn up towards the axis of vibration of the arm, one end of the chain will necessarily move through a less space than the other, and thus cause the wheel with the scroll cam attached thereto to turn on

its axis, and thus to vary the motion of the top rack, and thereby adapt the motion of the spindles to the varying diameter of the base of the cops. The screw in the vibrating arm that carries this slide is in connexion, by means of appropriate cog wheels, with a horizontal ratchet wheel, which is free to move when the arm vibrates in one direction, but held by the hand or catch when the arm vibrates in the reverse direction, for the purpose of turning the screw to move the slide; and this hand or catch is governed by an apparatus called a butterfly, which is acted upon by an arm from the counter faller when the tension of the threads is too great, and thus throws the hand into the teeth of the wheel, that the vibration of the arm shall operate the slide, the hand or catch being disengaged at each running out of the carriage. The last of the third series of motions is the operation of the coping rail for operating the faller, which, being essentially similar to others, needs no special notice here.

"At the end of the running-in motion of the carriage, a pin, on an arm projecting from the shaft of the crank that operates the under rack, liberates the catch that holds the connecting rod, by which the backing-off motion is effected; and so soon as it is liberated, the weight of the machinery attached draws it back; and to prevent any sudden jar by this operation, the crank pin which operates the connecting rod in one direction is so governed in its revolutions as to be nearly a semirevolution from its point of departure at the commencement of the backing-off operation, so that the force required for carrying it back to this position is sufficient to ease off the motion of the returning parts. This crank pin is held in the position just indicated by a brake within the second fast pulley, and this brake is connected, by a joint link and lever, with the arm of the connecting rod of the backing-off apparatus, which, when drawn back, forces the brake in contact with the pulley, and arrests the train of wheels and this crank pin in their appropriate place.

"When finishing the cops, it is important to wind the threads on tight at the point, particularly as the upper ends of the spindles are tapering. This is effected by forming the connexion between the chain and the end of the top sliding rack by means of a vibrating frame, from which projects another arm, that has a chain jointed to it extending to and winding on an arbor, which arbor has a ratchetwheel on it, which is carried a part of a revolution at each operation of the mule by a hand on the arm of the connecting rod of the backing-off motion; and this auxiliary chain is of such length that it continues to be wound upon the arbor without affecting the operations of any part of the machinery until the cops are nearly completed, and then it becomes so short as to be brought in contact with a permanent arm towards the end of the winding-on operation; and when thus brought in contact with this arm, it suddenly shortens the chain. that forms the connexion between the two racks, and necessarily increases the rotation of the spindles, which, as a necessary consequence, draws the threads tighter on the spindles."

Claim."I have thus described the general character of my invention, and the manner of constructing and using the same; but before

pointing out what I claim as my invention, I wish it to be distinctly understood that I do not limit myself to the precise form and construction of the various parts employed, nor to the precise arrangements described, as I consider all mechanical equivalents as within the limits of my invention; what I claim, therefore, as my invention, and desire to secure by letters patent, is

"1st. The disconnecting of the mechanism employed in running out the carriage and turning the draw rollers from the mechanism, which gives the whirling or spinning motion to the spindles when the driving power is shifted from these, the first series of motions, to enable the spindles to continue their motion by inertia, independent of the other motions, by means of the clutch box, (or its equivalent,) which forms the connexion between the three movements constituting the first series of motions, whereby the momentum of the spindles can be employed for preparing the parts for the backing-off motion, substantially as described.

"2d. The method of preparing the parts for the backing off motion, by means of the momentum of the spindles, by connecting them with the backing-off apparatus by means of the friction clutch, or any equivalent therefor, substantially as described.

"3d. The backing-off apparatus, consisting of the combination of the top sliding rack, which communicates motion to the spindles; the rocking shaft, with its cam and spring brake, and other appendages, and the connecting rod, operated by the crank; all substantially as described.

"4th. The method of decreasing the backing-off motion to correspond with the increased length of the cops, by means of the slide in the intermediate arm of the connecting rod, (between the two sections of the connecting rod,) by means of which the rocking motion of the rock shaft is gradually decreased, substantially as described.

"5th. Combining the train of wheels which actuate the backing-off motion of the carriage by means of a clutch, substantially as herein described, which admits of the necessary backing-off motion before. the tooth of the clutch starts the carriage, whether this be effected by a clutch, or by any other means, substantially the same.

"6th. Running in the carriage by means of a crank motion, which actuates a sliding rack that communicates the desired motion to the carriage, so as to start and arrest it gradually, substantially as described, to avoid any sudden strain or jar upon the threads.

"7th. The method of communicating the winding-on motion to the spindles from the main rack, which runs in the carriage, by combining the said main rack with the top sliding rack by means of a chain and scroll cam, or their equivalents, by means of which combination, in connexion with the form of the cam, the motions of the spindles so correspond with that of the carriage as to wind the thread on the conical forms of the cops, as described.

"8th. The method of varying the winding-on motion of the spindles, to form the base of the caps, by means of the slide and chain, which vary the motions of the wheel that is attached to and which rotates the scroll cam, substantially as described, whether the slide be oper

ated by the vibration of the arm on which it slides, or by any other means, substantially as herein described.

"9th. The method of regulating the motion of the slide that varies the motion of the scroll cam of the winding-on motion, by means of what is termed the butterfly and its appendages, when this is acted upon by the counter faller, operated by the tension of the thread, substantially as described: and

"10th. The method of winding-on the threads tighter at the points of the cops, when finished, than by means of the apparatus which gives to the top sliding rack an increased motion towards the end of the operation; the said apparatus consisting of a chain, which is connected with the chain that forms the connexion between the main and top rack, and which is gradually wound up, and strikes against an arm towards the end of the operations of the mule to shorten the connexion between the two racks, and thus increase the winding-on motion of the spindle, as described."

2. For an Improved Self-Feeding Straw Cutter; James T. Wade, Augusta, Georgia, October 3.

Claim."What I claim as my invention, and desire to secure by letters patent, is the combination of the brushes with the gauge boards, vibrating frame, and cutting blade, substantially in the manner and for the purpose herein set forth.”

3. For an Improvement called "the Inclined Piston;" James Richards, New York, October 3.

Claim."What I claim as new in my invention, and desire to secure by letters patent, is the use and application to pistons of the three or more inclined elastic wings, breaking joints, and fitted to each other as described, of cast iron, or any suitable material, working out the principle I have above mentioned, and combined together, and with a piston bulkhead and follower, or any substitutes for them, and working together in manner substantially as above set forth and made known."

4. For an Improvement in Looms for weaving Ribbons, and other narrow stuffs; Carl V. Ganahl, (assignor to Francis V. Ganahl,) Junsbruck, Austria, October 3.

The patentee says, "The nature of my invention consists in constructing a loom for weaving ribbons and other narrow goods, which can be driven with great rapidity, by steam or other power, requiring only one person to tend 20 to 50 stands, all of which are driven by one axle, as there is a regulator and stop attached to each stand."

Claim."What I claim as my invention, and desire to secure by letters patent, is, first, the pickers constructed as above described, and also their combination with the lathe, in the manner and for the purpose herein set forth.

"Secondly, I claim regulating the take-up motion, by means of a roller which rests against the cloth beam, acting on an upright rod, with a gauge thereon to curtail gradually the motion of the pawl, and thus decrease the distance the cloth beam turns as it enlarges, constructed and combined substantially as herein made known.

"Thirdly, I claim the combination of the jacquard, constructed as above described, with the upright rods, in the manner and for the purpose before specified.

"Lastly, I claim the apparatus for stopping the loom-that is to say, the forked lever, arms, eccentric, hook, catch, and upright barconstructed and arranged as herein described, in combination with the shipper for casting off the belt and stopping the loom."

5. For an Improvement in the Glass Furnace; Deming Jarvis, Boston, Massachusetts, October 3.

Claim."What I claim as my invention and improvement, is extending the fire-place and flame chamber entirely around, and so as to encompass the melting pot, in the manner substantially as above described, instead of placing the fire-place entirely on one side of the pot, as is the custom in ordinary glass furnaces."

6. For an Improvement in Threshing Machines; Walden Eddy, Duchess county, New York, and John A. Toplin, Washington county, New York, October 3.

Claim." What we claim as our invention, and desire to secure by letters patent, is the mode of inserting the teeth in the cylinder to threshing machines, in combination with the manner of making the threshing cylinder in several sections of cast iron heads, the whole constructed and operating in the manner and for the purpose herein before described."

7. For an Improved Stove for Cooking and Warming Apartments; Adam C. Conde, Schenectady, New York.

The patentee says, "My stove, in its general construction, is similar to many other cooking stoves. It has two ovens, one of them placed above the other, with a flue space between them; but this flue space, and one in front of the two ovens, and at the back of the upper oven, do not admit any portion of the draught from the fire chamber, but used for the passage of air that is heated by the action of the fire through the back plate of said fire chamber, and the air so heated is to be subsequently conducted through suitable tubes to the apartments which it is desired to heat. The draught direct from the fire is conducted to the exit or smoke pipe, through flues especially appropriated to that object."

Claim. Having thus fully described the manner in which I construct and arrange the flues of my air-heating stoves, what I claim therein as new, and desire to secure by letters patent, is the particular
