LUCIUS J. KNOWLES, OF WORCESTER, MASSACHUSETTS.
IMPROVEMENT IN DEVICES FOR SECURING THE BARS IN HEDDLEFRAMES.
Specification forming part of Letters vPatent No. 1684,095, dated-September 28, 1875; application filed August 26, 1875.
To all whom it may concern Be it known that I, Lucius J. KNowLEs, of the city and county of Worcester and Oommonwealth of Massachusetts, have invented certain new and useful Improvements in Devices for securing the Bars in Heddle-Frames 5 and I do hereby declareV that the following is a full, clear, and exact description of the same, reference bein ghad to the accompanying drawings, forming a part of this specification, and in which- Y Figure l represents a front or side view of a harness-frame with my improvements applied thereto. Fig. 2 represents an opposite Fig. 3 represents a horizontal section on line A B, Fig. 1. Fig. 4 represents a horizontal section on line C D, Fig. l; and Figs. 5, 6, 7, and 8 represent, upon an enlarged scale, side views of the ends of the heddle-supportin g bars and their fastening devices, as will be more fully described hereafter.
To enable those skilled in the art to which my invention belongs to make and use the same, l will proceed to describe it more in detail.
In the drawings, the parts marked A A represent the top and bottom pieces, and the parts B B the end pieces of the harness-frame secured together in any well-known manner. The end pieces B B are inortised to receive the heddle-bar supporting and holding pieces a a, the outer ends of which are reduced, rounded, and provided with screw-threads and nuts b, as fully indicated in the drawings. The parts a, are bent, as shown at 5 in the drawings, while their extreme inner ends are provided with hooks 2, which hook into the slots 3 in the ends of the heddle-bars C and D, as also fully indicated in the drawings. The hooks 2 being turned in the opposite direction from the bends 5, thereby causing the heddle-bars to stand, when secured in place, incentral positions as respects the harnessframe, as shown in the drawings, whereby, when the heddles have been placed in position upon the bars G and D and the nuts b screwed up so as to draw the parts a a ofeach bar in opposite directions, the bars will be held securely in place and properly extended to support the heddles, so that those of one harness will not rub or chafe against those of another in the operation of the loom.
To put on or take of the heddles, the nuts b of two end pieces, a, are loosened sufliciently to allow of the withdrawal of their hooks 2, when the heddles can be put on or taken off', as may be desired, and that too without the Withdrawal of the bars C and D.
The parts ct, which fasten the bar G, are made from the same piece of material from which the bar itself is made. The bar Gis first made with its ends reduced and screwthreaded, and provided with nuts b, after which the ends ct are cut oft' by a die-punch, so made that the hook part 2 will be punched or forced out to leave the ears 4 4, which project beyond the hook and bear against the side of the end of they bar C, as shown in Figs. 1,2, 3, 5, and 6, thereby rendering the connection more secure and firm.
In making the heddle-bars and their fastening connections in this manner, the bar, when first made, should be long enough to compensate for decrease in length occasioned by the lap -joint made at each end, as above described.
If preferred,l1owever, the parts a may be made ot' separate pieces and with a full back, the hook 2 being on one side, as shown in Figs. 4,7, and 8. In this case, however, as in the other, there are bearing-surfaces adjoining the hook, which serve to assure and steady the bar. 4
In many cases old bars can be altered over at slight expense, their length being suflicient to allow of the shortening to form the lapjoint.
Having described my improvements in harness-heddle-bar holding and connecting devices, what I claim therein as new and of my invention, and desire to secure byLetters Patent, is-
The combination, with the end pieces B B, of the harness-frame and heddle-bars provided with end slots 3 3 of the holding and supporting pieces a a, provided with bends 5, hoolgs 2, bearing-surfaces adjoining the hooks 'for steadying the heddle-bars, and screws and nuts b, substantially as and for the purposes set forth. y
