No. 5. VOL. IV. ENLARGED SERIES.-NOVEMBER, 1844.

Specification of the Patent granted to BENJAMIN BAILEY, of Leicester, Frame Smith, for Improvements in Machinery for Manufacturing Looped Fabrics.-Sealed February 24, 1844.

WITH AN ENGRAVING.

To all to whom these presents shall come, &c., &c.My invention relates to a mode of constructing and working what are called the presser bars of machinery used in making looped fabrics.

It is well known that the two classes of machinery which work with needles, requiring presser bars, are frame work knitting machines, which work with one thread looped on many needles, and the successive loops of the same thread are looped into the previously made fabric, as is well understood; and this is the case whether the fabrics produced are plain stocking or knit fabric, or whether the fabrics are made more or less open and ornamental; and the other class of machines are warp machines, which vary in some of the details according to the fabrics produced thereby, by looping many warp threads into each other. The two classes of machines are well known, it will therefore be unnecessary to enter No. 5.-VOL. IV.

S

into any description thereof, further than will be necessary in pointing out how my improvements are to be applied

thereto.

Description of the Drawings.

Fig. 1, represents so much of a vertical section of a frame-work knitting, or stocking machine, as will enable me to describe my invention.

Fig. 2, shows part of a front view of some of the same parts as are shown at fig. 1.

The nature of the other views being written on the drawings, it will not be necessary to repeat them here. The machinery shown is worked by means of a rotatory axis; I have not, however, thought it necessary to show the means of giving motion to the various working parts of the machine, they forming no part of my invention, and the names of the ordinary parts which are shown are written on the drawings. It will be seen that the sinkers are slightly altered at the lower parts; a, is the presser bar, which is carried by two arms, b, b; these two arms move on axes, c, c, affixed to the ends of the carriage, which carriage with the working parts move to and fro, as is well understood, on plates, e, so that the presser bar is carried to and fro with the carriage. f, is a spring, there being one at each end, supporting the presser bar, and parts connected therewith. g, is a connecting rod, one at each end of the presser bar, attached to an arm h, affixed to the spindle bar, i. On the arm, h, is a truck, or roller, which bears against the cam, j, affixed on the rotatory axis, k. All these parts are similar to those employed in like machines, they being only varied to adapt them to the movements required for the novel mode of constructing and working the presser bar, which I will now proceed to describe.

The presser bar, as heretofore, works in front of the sinkers, but is so arranged that a very short length of movement is required, and at the same time the parts of the presser bar are at all times between the sinkers, and in fact guide and protect the sinkers from bending laterally, and it is these peculiarities of constructing and working of presser bars of machinery making looped fabrics, that constitute the improvements secured under the above recited letters patent. The presser bar is divided into as many parts, 1, 7, as there are needles, and so that one of

the parts, 1, enters, and constantly works between two neighbouring sinkers, whereby on the one hand the presser, 7, for each needle, is guided in its work by the sinkers, and the sinkers are sustained and guided by the pressers,,, which will be found very important when working quickly; and owing to the shortness of the motion required to the presser bar, aided by the mutual guiding and supporting of the pressers, l, and the sinkers, the speed of the frame may be quickened with safety. The drawing shews the pressers, 7, cast in leads so that they all press when any of them press; but this is not absolutely necessary, as the workman may if he desire it, for particular fabrics, have the pressers, l, moveable in respect to each other, so that any of them may be moved out of the way when the others are pressing.

Figures 3, 4, 5, and 6, shew the various positions the sinkers and pressers assume in working a course, by which it will be seen that the pressers, l, never depart away from between the sinkers. I have not thought it necessary to shew any parts of a warp machine, as a workman acquainted with such machines, aided by the description herein given, will readily construct a presser bar, with separate pressers, 1, and work such bar in order to press on the beards of the needles.

Having thus described the nature of my invention, and the manner of performing the same, I would have it understood that I do not claim any of the parts separately, nor do I confine myself to the precise details, so long as the peculiar character of my invention be retained. But what I claim is the mode of constructing and working presser bars of machinery for making looped fabrics as herein described.-In witness, &c.
