Be it known that I, CLEMENS UNVERZGT, of Terre Haute, Indiana, have invented certain new. and useful Improvements in Looms; and I hereby declare vthe following to be a full, clear, and exact description Aof the same, reference being had to the drawings which aecompanythis specification, forming a part of the same, and l to the letters of reference marked thereon. .In the drawings- Figure 1,-plate 1, is a perspective view of my improved loom, and v Figure 2 is a vertical'sectional view, showing the batten-posts, picker-staffs, spring, and triggers.

Figure 1, plate 2, shows the notched revolving plate with its operative shaft, and provided with separate single, double, and triple removable and adjustable arms.

Figure 2, plate 2, is a perspective view of an elongatedoval oat or feather, which, traversing the grooves of the grooved plate, operates the traverse-bar and sets and releases the triggers alternately.

Figure 3, plate 2, is a perspective view of an oblong, curved, rectilinear plate, the upper surface of which is grooved, and-so arranged as, by means of the float or feather which works in the same, to -produce the backward and forward motion of the traverse-bar, to which the float or feather .is attached, and also showing the triggers in connection with the traverse-bar.

Figure I, plate 3, shows a single arm with a hub fitted for the shaft which operates the heddles, and

Figure 2 is a hubwith three arms.

Figure 3, a hub with two arms, (and with additional arms shown in dotted lines,) and Figure 4 shows parallel arms upon the same hub. l

Figures and 6 are views of an adjustable hanger with pivots or pointed journals, -upon which the arrn.

shaft is hung, .and upon which it revolves.

Figure 7, plate 3, is a view of the revolving notched plate, and the arm-shaft which it operates, and'to which it is attached. l

Figures 8 and 9 are views of a like plate provided with six and eight sides and notches respectively, and capable of being used upon a. shaft of corresponding form when a greater number of arms maybe requisitel Figure 10, plate 3, is a. side view of the adjustable hanger, showing the screws and bolts by which it'is I .attached to the rail.

Figure 1, plate 4, is a top view of the upper section of the loom, showing the arrangement and connection of the diierent parts thereof, and the position of the triggers in dotted lines and colors, together with their relative positions to the picker-staffs, both when set and when sprung,

Figure 2, plate 4, is a side view of the ratchet-bar in connection with the revolving notched plate, which it serves tp rotate by its backward and forwardmovement.

In the figures upon each plate, like figures refer to like parts.

'llo enable those'skilled in' the'art to manufacture and use my said improvement, I will proceed to describe the same.

In iig. 1, plate l, A A A A A represents the framing of @hand-loom of ordinary construction. B is a crank attached suitably'to a balanee-whcel, C, which, together with a similar wheel, are placed at opposite ends of a shaft, D, which is properly secured and revolves in boxes resting upon-the front ends of the side piecesof the framing A A. Thewhecls C C are each prcvidedwith crank-pins, te which are attached the pitmen E E', at their forward end, while the opposite ends ofthe same are properly connected to the hatten F, and situated upon the outside of the framing ofthe loom, and by the turning of the wheels a forward and backward morir is given to the hatten by the action of thc pitmen E E. The betten is hinged, by the 'hatten-posts-I I', tothe lower sid'e pieces of the framing of the loom, upon which it is supported in a suitable manner, and is provided at each end with shuttle-boxes in which are tension-straps, T T', .which act upon the shuttle to hold it both downward and backward as it is received and discharged `from either end inthe shuttle-boxesG G. -H repre. sents the reed, which is of the ordinary form,l lM M are slotted orgrooved standards, attached to the'outer Vside or inner side of the upper. side rails 'of the framing perpendicularly, and operate as a guidelack for-,fthe

rise and fall of the hcddle-frames -N N N N. These heddle-frames are of the ordinary form, and can be used in such numbers as may b required. The heddles are raised either separately or in such combinations as may be required in the guide-rack, by means of revolving arms, the outer ends of which are of circular form, and which are fitted upon and operated by a shaft, a, as sce'n in iig. 1, plate 2. .This shaft, as shown, is square, and is rigidly attached to and moved by the notched plate b, plate 2, g. 1. The arms 1' '2' 3' 4', Snc., may he constructed single, double, triple, or` to any required number, upon a single hubor centre, and are so ittcd'as to be put on or taken otf for the purpose of changingA their relative position, and thus change and control the movements of the heddles. When in position upon the shaft a, they are secured by the key ol or in any other suitable manuel'. The shaft a has a conical opening in each end, in which are inserted the pointed journals d d, figs. 5 and 6, plate 3. These journals are attached to the hangers, as seen in figs. 5 and 6, plate 3; and the upper surface, a, plate 8, gs. 5 and 6, of the hanger is provided with slots or openings for the screws, which secure it, so that 'in case of the pointed journals -becoming worn or loose in `their bearings, the hangers may be set up closer together, and thus secure a perfect centre.

In plat-e 2, 1, b is an equal-sided revolving plate, provided with notches or catches at each corner, and rigidly secured upon the shaft a. The drawings show one constructed with four sides, and notches to correspond.; but thisplate may be formed hexagonal or octagonal, or otherwise, as the increased number-of heddles or of arms upon the shaft may render necessary, as seen in'figs. 8 and 9, plate 3.

v Fig. 2, plate 2, represents a iloat or feather having a stem or standard, a, a collar, I), und an oval shoe or bottom, e. 'Ihe stem or standard a is fitted into and occupies a. hole in the central portion of thc'traversc-.bar F', figz 3, Aplate 2, and operates said bar, as will be hereinafter shown.

Fig. 3, plate 2, is a perspective view of a grooved plate or frame attached at either end to the erossframings of the-loom. Its upper surface is arranged with two parallel grooves nearvthc outer edges of the plate, as shown at B B, fig. 3,'plate 2; connected with and conneetirfg. which are diagonal groovesl,1l' B". The traversc-bar F', in which the stem a ofthe iloat or feather is fixed, occupies a central position in the battenrail, upon its lower surface, and immediately beneath the shuttle-race. This bar is constructed with an offset or shoulder near each end, at which the pins e e are inserted, for the purpose of operating' the triggers K K'. The extreme ends of the traverse-bar F' serve to carry back alternately to the setting-point the picker-staffs L L', where the pins e e, producing an oscillation of the triggers K and K', alternately stop and release cach' picker-staff which throws the shuttle, by means of the wires or cords traversing the shuttle-boxes, an'd attached lto the shuttle-blocks therein. The shuttle is thus thrown by the backward motion of the hatten, and near the centre of its motion, leaving the hatten free play, as it comes forward, to beat up the c loth.

It will be seen that as the ratchet-bar A' completes the fullone-.quarter revolution of the plate Z, the angle :e of its lower surface is brought into contact with the straight side ofthe plate b, and the head m of the ratchet-bar A', entering the bracket B, plate 4, fig. 2 holds the heddles, harness, and shed fixed during the concussion of beating up the cloth by the hatten.

Attached to the head m of the ratchet-bar A' is a strap or cordrunning over a pulley on the side rail, and along the side to a peint forward of the battenpost, where it passes through a 'loop and is returned to the hatten-post on that side, and is secured toit. At the opposite end of the ratchet-bnr is secured a strap, C, which, passing around a pulley, G, iig. 1, plate 4, is attached directly to the opposite hatten-post.

In the grooved plate A, plate 2, g. 3, it will be seen that the front ends of the' transverse grooves B B are deeper than lthe corresponding ends of the side grooves, while at the back ends they are equally higher,

which arrangement, combined with the operation of the said. grooves, insures the proper direction of the float or' feather c, which always-comes down on the outside grooves and returns in the diagonal grooves.

It will be observed that the traverse-bar F','to which the lioat or feather is attached, operates the triggers, and consequently the picker-stads, setting one and releasing the other simultaneously, and at vone movement of the bar,' and produced by the transit of the float or' feather through one of the transverse grooves, occupying about one-fourth of the traverse of the hatten, and relieving the picker-staifs from any strain during the other three-fourths of its vibration. I

'One of the features of my invention consists in the construction of a loom without treadles, which makes it cheaper and easier of operation. l v

Another feature will be found in the facility with which any reasonable number and variety of combinations may be formed by the arrangement, as shown, of the revolving notched plate, the arm-shaft, and the arms.

And still another, in the traverse-bar F', operating in themanner described.

The arm-shaft a, iig. 1, plate 2, is readily removed for the adjustment af the arms, by releasing the nuts iz', fig. 10, plate 3, by which the hanger is thus disengaged, and is as readilyreplaced in the same manner.

Havingthus fully described my said improvements, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the grooved plate A, hatten F, feather a 6 c, and traverse-bar F', when arranged and acting substantially'as and for the purpose hereindescribed. l

2. The triggers K K', as set forth, in combination with the traverse-bar F' and its pins e e'.

3. The combination of the traverse-bar F', feather a 6 c, and the grooved plate A, constructed and operating as herein fully set forth.

4. The ratchet-bar A', with its head m and lower inclined surface sa, in combinationwith the inclined bracket B and notched revolving plate-wheel b, as and for the purposes set forth. Y

5. The combination of the shaft D, wheels C C', pit'men E E', batteri F,`traverse-bar F', feather a I) c, and grooved plate A, all as constructed and arranged, as is herein substantially set forth.

` 6. The combination of the siidingratohet-br A, constructed as described, with the strap C, cord D, or their equivalents, when operated bythe botten F,'for the purposes set forth. A

7. The arrangement and combination of devices herein set'forth, bj which the picker-stais are set and sprung alternately.simultaneously by the backward motion of the hatten.

8. The combination of the picker-staffs L L, triggers K K', and traverse-bar F', when arranged and constructe as is herein set forth. 'A CLEMENS UNVERZAGT.
