TO ALLIVHOM IT MAY CONCERN:

Be it known that I, JOHN WEBER, of Bourbon, in the county of Marshall, and State of Indiana, have invented a new 'and useful `Improvement in'Iiooms; and I do hereby declare that thefollowing i's a full, clear, and exact description of the'construction and operation' of the same, reference being Vhad to the annexed drawings andiletters of reference marked thereon, making a part of this specification, in which#- Figure 1 is a front elevation of the loom.

Figure 2 is an elevation of a part of my invention for regulating'the position of the shuttle-boxes.

Figure 3 is an elevation of the left-hand side of the loom, shown on drawing B; and

Figure 4 is a sectional elevation of the shuttle-race.

The general character of my invention relates to'that class of looms which'are intended to weave auto# niatically, tho putternbeiug governed by the jacquard; and its nature consists, irst, inthe use of a revolving' rectangular pattern-bed, over which the pattern yis made to pass when bringing the harness into posit-ion for vseparating the warp for the shuttle to pass through and make the stitch or over-cast, forming a part 0i' the figure, corresponding with the holesl in the patternfey'lider; and in connection with this, the use of such mecha ical appliances as to successfully operate the pattern-bed; second, in thezuse of a ratchet-pinion attached to the upper cam, and giving suitable motion to the lever controllingthe height o f the shuttle in the beam, in order that the under or over-shuttle movement may be had, which is necessary inv the weaving of igures.

In order to give a correct understanding oi' my invention, I will rirst refer to the .common parts of the loom,- as represented on drawings A and B.

A shows the frame-work of the loom, which is made similar to those now in common use; B is' the shuttlel beam; V, the'reed; T the picker-staffs; 86,'the harness-slats; and I Q R S -the devices for winding the woven goods upon the beam 2. I represents the revolving pattern-cylinder, adjusted inthe sliding frame Gr II. This cylinder has four rows of holes, 4, corresponding 4in number with the indicators 5, which may pass through holes madein the common pattern eardsandinto the holes 4 when the loom is in operation. The sliding` frame GII is operated by means of the lever F, connecting-rod I) E, and crank 7. 10 representsl the ratchet-pinion, attached to the shaft of the pattern-cylinder I, which is operated and made to revolve, when the sliding frame isl descending, by means of the hook J catchingv the arms n, thus moving the pattern-cylinder I one-fourth of a revolution, and bringing the holes 4 directly underthe indicators 5. The shuttle-beam B is connected to the wheel by means of the connectinggshaft 11, so that the beam'B drives up one thread of woot' as soon as the indicators 5v have regulated the proper part of the harness so as to divide thewarp for making the required gur'e. K is a bar, passing through the guides 13, and made to press downward and'facilitate the turning of the ratchet-pinion I by means of the spring 12 and foot o, the latter resting hat upon the sides of the pinion when in operation, .at

each quarter revolution. 14, iig. 1, drawing A, shows the cords connecting the indicators 5 with the harness-slats I &, passing over the pulleys 15 and 16. Fig. 2, drawing A, represents my improvement for regulating the position of the shuttle in the beam B, iig. 1. 29 shows a section of the shaft, operated .by the common gearing of the loom, and to which shaft is ,attached theecam, 18, that strikes the friction-wheel 17, supported on the vlever 16, and gives motion to that lever. The dotted lines 30Ashow the position of the lever 1d when forced downward by means of the cam 1S. l 19 represents the hook attached to the lever 16 by means ofthe joint 31. Near the top of the hook 19 is the pinion 34, having the arms 32, similar to thearms n, figs. 1,3, drawings A and B. 21 shows the upper cam, rigidly attached to the. pinion 34. This cam, in its rotation, strikes the projection 20, attached to the controlling lever 26', which is forced downward at each half revolution of the cam 21, causing the cordvW, attached to the lever 26, and the arm 35, iig. 1, projecting from a rock-shaft, 29, to pass downward,

elevating the arm 36 on same rock-shaft, carrying upward the cord X, which is attached to the adjusting plate 37, iig. 4, drawing B. Theadjusting plate 37 is suspended by thecord X, and supports the shuttle-beds 38, which will occupy the position shown'by the dotted-lines 39 at each half revolution of the upper cam 21, lig. 2,

drawing A, thus giving the under or over-shuttle movement essential in weaving gures. 24 shows the rod tov which is attac-hed the foot 25, similar to the rod and foot shown in tig..1'. 27 and 28 are`the standards through which the rod Qeleslides when' the foot 25'is forced backward by means of the rectangular pinion' 34 and the hook 19. This rod and foot are used lto assist in turning 'the pinion .34: after the hook 19 has lost most of its foreefinI its downward movement. The spiral spring 23 chaises the foot 25to press against the 'pinion 34,'and as nresult,

`will speedily bring it into the position shown in the drawing after either cerner of the. same has been forced against the foot 25 by means of the hoolc`19. 4Q represents tbe springA `which forces nupward the lever 16 after the cam 18 has forced it down, as shown by dotted lines '30. N N represent common shuttles. i

` Operatz'qn.- The pattern cards can be made adapted to .any style desired, after which they must be put on the patterneylinder I, and the projections 41 will cin-ry tl'ie -patternforward as the Vcylinder is rotated. The'loom-may be drivenby hand or by power, ns most convenient. The most of' thegearing necessary in giving motion to tbe weaving apparatus is o'mitterl in the drawing, it being so simple as to need no illustration.

Having thus fnlly described my invention, what I claim as new, and desiro'to-.secure by Letters Patent vof" the United States', is-I f The combination of the lever 16,l cams 17 and 18,`\vitl1 the hook 19, pinion 34, bar 24, spring' 23, lever 2li, earns Q()Aand 2,1., when constructed to operzite the shuttle-plate 3T, substantially as feet foi-th. JOHN R. WEBER.'
