Specification of the Patent granted to J. WILLIAM Cole, of Coventry, in the County of Warwick, Warehouseman, for Improvements in Looms.-Sealed December 23, 1845.

WITH AN ENGRAVING.

To all to whom these presents shall come, &c., &c.My invention of certain improvements in looms relates more particularly to such looms as are employed in the weaving of ribbons.

Firstly, in certain new mechanical combinations and arrangements of parts constituting looms for the above purpose, and by which several shuttles or rows of shuttles may be advantageously employed, whereby several similar pieces of ribbon may be simultaneously woven in one and the same loom; and I have found in practice, that for a loom, the batten of which is nine feet wide and capable of weaving nine pieces of ribbon of four different colours, that about thirty-six shuttles, or four rows of shuttles of four in each row, are as many as can be conveniently and beneficially used.

And I would remark that I am aware that two sets of shuttles have been employed in the weaving of ribbons previous to the date of these my said improvements; and I desire it to be distinctly understood that the peculiar feature of this part of my said invention consists in the application of more than two sets of shuttles in one loom for the weaving of ribbons, and in arranging or disposing and actuating such said shuttles, and the batten containing the shuttles, in such manner hereinafter particularly described, set forth, and represented, by the illustrative drawing hereunto annexed. I would also desire it to be understood that the same principles may be applied to more than four sets of shuttles if necessary.

The second part of my said improvements consists in another arrangement of certain parts, which I designate drivers or peckers, employed for actuating the shuttles, such arrangement being more particularly calculated for the manufacture of that class of goods known and distinguished as checks and tartans, which require one colour or shuttle, or row of shuttles, to be worked several times

in succession before bringing into operation the next row of shuttles, containing weft of a different colour.

I would further remark that in the next illustrative drawing the mechanical arrangements employed for effecting the several operations of beating up, raising, and lowering the batten, winding on of the finished work, and shedding of the warp, being well known to every practical weaver, I have omitted such parts, and have confined myself principally to the representation of those parts which constitute these my said improvements; and, in order to explain my said invention as completely as possible, I will proceed to describe the arrangement and combination of parts which I consider best calculated for carrying my said invention into practical effect.

Description of the Drawing.

Fig. 1, exhibits a front elevation of the sliding batten, hereafter mentioned, showing the improvements attached thereto, the work rollers (represented at figure 1*) being removed from the front thereof.

Fig. 2, is a partial front elevation of the batten containing the reeds, showing also the sliding batten in two parts, each of such parts being shown at different heights, for the purposes hereinafter mentioned.

Fig. 3, is a transverse and vertical section, taken through the line, A, B, at the figures 1 and 4.

Fig, 4, represents a back elevation of the sliding batten, showing the arrangement of parts for actuating the shuttles.

Fig. 5, is a front elevation of the sliding batten without the shuttles.

Fig. 6, is a transverse and vertical section thereof taken through the line, C, D, at the figure 5.

Fig. 7, represents an elevation of an arrangement of parts to be employed for placing the shuttles in their proper position.

Fig. 8, is a top plan view thereof.

Fig. 9, is a transverse and vertical section thereof, taken through the line, E F, at the figure 7, showing, also the arrangement of parts to be employed for actuating the shuttles. Similar letters of reference are placed upon and denote corresponding parts, in so far as such parts appear, or can be seen at each of the figures respectively.

A, A, marks a portion of the framing of the loom, to one part of which the levers, B, B, are attached by pins or studs, c, c, which are the fulcra thereof, to one end of each of these levers there are attached rods or chains, D, D, and the lower ends of these rods or chains are connected by hooks, E, E, to the sliding batten, F, F, by which it is suspended, and the said batten is guided in its proper course by guide bars, G, G, which are fixed to the batten, H, containing the reeds, such last-mentioned batten being attached to the loom in the usual manner, 1, 1, mark four rows of shuttles working in races and grooves, K, K, formed in the batten, as clearly shown at figures 4 and 5, and the said shuttles are retained in the said races or grooves by the shuttle being constructed with shoulders, I, 2, as shown at figure 6. L, M, N, O, mark drivers or peckers for actuating the shuttles. P, P, mark openings formed in the sliding batten, F, such openings being opposite to the reeds in the batten, H, through which passes the warp in the usual manner; Q, R, mark sliding bolts or blocks of wood for determining or governing the height to which the sliding batten, F, F, is raised, these bolts or blocks are connected to the jacquard machine by cords, 3, 4, and to the other end of the said blocks there are attached check springs, 5, 6, for returning them to their original position when not acted upon by the jacquard machine. S, T, U, V, mark sliding bolts or rods working in grooves formed in the back and front of the sliding batten, as shown at figures 2, 3, 4, 6, into these bolts or rods, and in a vertical line with one end of each of the shuttles, in each row of shuttles there are fixed the drivers or peckers, L, M, N, O, and to each of such bolts or rods there are attached handles, 7, 8, 9, 10, by which the shuttles of one or other of the rows of shuttles may be simultaneously acted upon by the attendant, or in some instances the movement of the bolts may be effected by mechanical means similar to those now in use for working one set of shuttles by power, there are slots, 11, 12, formed in the front of the sliding batten for connecting the handles 9, and 10 to the bolts, s, and u, and the handle, 10, is guided in its proper course by antifriction rollers, 13, 14, 15, and the piece, w, which has a slot formed therein through which the said handle works. At the figures 1, and 3, x, marks a lever of the third order, one end of which has its fulcrum upon a pin, Y,

attached to the framing of the machine, the other end of this lever rests upon a cord or chain, z, which is attached to the levers, B, B, and there is a weight, z', placed upon this end of the lever, x, which weight is somewhat heavier than the weight of the sliding batten and its appurtenance for the purposes hereinafter mentioned.

The operations of this machine are as follows: Motion being imparted to one or other of the handles, 7, 8, 9, 10, in the direction of the arrow's flight at figure 1, will have the effect of throwing the shuttles along the grooves and races, K, and the said shuttles will be arrested by coming into contact with the opposite sides of the drivers to those which impelled the shuttles, and having performed the operation of beating up the shuttles may be again returned by a reverse movement of the handles, and when it is required to bring the next row of shuttles into operation, so as to introduce weft of a different colour to the first, the same may be effected in the following manner: to the lever, x, there is attached one end of a cord or wire, 16, the upper end of which is attached to one of the hooks of a jacquard machine, the cards of which are pierced in conformity with the pattern to be woven, and as such hook is lowered by the grife or grate of the jacquard, the weight, z', will descend, and imparting motion to the levers, B, B, will cause a vertical movement of the sliding batten, F, and in order to insure the raising of the said batten to a given distance, I employ sliding bolts or blocks, Q, R, which are in the position shown, as also are the shuttles at the commencement of the operation of weaving, and after the first race of shuttles have been thrown a sufficient number of times and before bringing the next row of shuttles into operation, the bolts, R, R, are brought into the position shown at A, figure 2, by the action of the jacquard upon the cords, 3, 3, thus, as the sliding batten, F, is raised the blocks, R, R, coming into contact with the stops or guide pieces, G', G', will be arrested thereby, and the shuttles having performed their office the blocks, R, R, will be relieved by the action of jacquard, and the check strings, 5, 5, the blocks, o, are then brought under the stops, G', G', as shown at B, figure 2, by which, as the sliding batten is raised, the third row of shuttles will be brought into the position previously occupied by the first and second, and when it is required to bring the fourth row of shuttles into the position occu

pied by the third, the same may be effected by releasing the blocks, a, a, in a similar manner to the blocks, R, R, the sliding batten having now gone to the extent of its range, and the last or bottom row of shuttles having performed their office, the batten is then lowered by the action of the jacquard upon the cords and levers, B and D, so as to bring the first or top row of shuttles again into the proper position, and subsequently the following rows for performing the shoot.

And I would remark, that in cases where each of the rows of shuttles are not required to be brought into operation in succession, the sliding batten may be raised and lowered by the attendant pressing upon a treadle which is in connexion with the levers, B, B, as shown by the dotted lines at figures 1 and 3, by which one or other of the rows of shuttles may be placed in the proper position for performing the shoot, as the nature of the work may require, or circumstances deem necessary. At the figures 7, 8, and 9, of the annexed drawing, the arrangement there shown differs from the before-mentioned arrangement, first by employing only one driver or pecker for each vertical row of shuttles, such driver or pecker being attached at its upper and lower ends to sliding bolts working in grooves in the batten which contains the reeds, as shown at figure 9, and secondly, in the application of rollers, e, e, placed in front of each vertical row of shuttles, for the purpose of placing them in a proper position (as the batten beats up), for being acted upon by the drivers or peckers. It will be seen, upon referring to the drawing at the figure 9, that the sliding batten is independent of the driver or pecker, and that as the sliding batten is raised, and one or other of the rows of shuttles are brought opposite to the part, a, of the drivers or peckers, they will be impelled thereby, and this arrangement is more particularly intended to be used in the weaving of tartans and checks as before-mentioned.

Having now described the nature of my said invention, and in what manner the same is to be performed and carried into practical effect, I desire it to be distinctly understood that I do not claim the exclusive use of any of the separate parts above-mentioned and referred to, except in so far as the same may be employed in combination and for the purposes of my said invention, neither No. 3.-VOL.
