Application filed August 25 1919. Serial No. 319,722.

T all whom it'ma-y concern-f Be it known that I, PETER G. GIELEN, a

citizen of" the Republic of France, residing at Paterson, 1n the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Looms, of which the following is a specification.

ThlS 1nvent1on relates to looms, and particularly to the type of looms that are -'de-' turning it at will and with a ratchet wheel @I which is engaged by a holding pawl and also by an actuating pawl 76, the latter mov: able up and down and held against the ratchet wheel by a spring The up and down movement of the pawl I; is effected by l a lever m from a lever 12', both fulcrumed in signed for weaving in 'an upright plane,

which is very desirable in the-weaving of 'certaln fabrics, as georgettas, in order to prea vent any possibility or the shuttle abrading the warps, and also because it enables the woven goods to be positioned so that it is 1n plain sight of the weaver and easily ac ccording to this invention the,

cessible. batten is arranged to reciprocate vertically, being suitably guided forthat purpose, and in order to prevent the intermittent shock incident to the change from the down stroke i to the up stroke of the batten and so insure a smoother action of the loom I provide resilient means to assume the down thrust of the batten. invention consists in providing'the batten structure with a shuttle box structure comprising a plurality.ofboxesshiftabh for. changing shuttles not .in a plane transverse to that of the mo'vementof the batten for beating up, as in the ordinary loom, but up and down, substantially in the same direction as the batten moves for beating up, suitable connections between said shuttle-box structure and the means in the frame for shifting it being provid'edso that its move- I Fig; 3 a fragmentary side elevation of achain connection 6" ments take place regardless of the movements of the batten structure.

j the top of the frame a is arrangedthe "cloth beam Z), and below this beam is an.

The batten 8 is arranged? to move up and down and has fixedthereon 'rea artl carriers-8 which slide "up anti-d n fixed vertical shafts 9 v mol'lnted, a loom frame. The batten structure v with the cranks 10 onf the: crank ushit by the pit'men ll. Due to the: Weight flf flt al batten structure and to the ehangeyin the direction of its movement. fromdo'wn tong j if crank shaft. here there are a large number of looms on a floor this becomes a serious objection whenever the beats of the looms happen to occur in the same cadence,

and of course 11. 1s in urious to the loom it self and more or less spoils the quality of the fabric being woven. To eliminate this shock I mterpose springs '12, preferably coiled about the shafts 9, between the frame,

andthe under side of the batten, in the preferred form leaving a spacebetween the batten, when up, and said springs, so that the latter .will be effective as a cushion at the downward end portion of the throw. This.

very considerably eases the action of the batten and practically entirely eliminates the shock and vibration referred to.

The batten has a vertical opening 13 (see Fig. 1, andalso indicated in dotted lines in Fig. 2) through which the sheet A '15 extends, and on the batten over this opening is fixed, horizontally, the reed 11-. The shut-' tle 15 travels from end to end of the batten structure over the dents of this reed as a race, its movements being caused by any suitable means, picker sticks 16 adapted to be actuated'by tappets 17 on the tappet shaft 18 driven by a gear 19 from the gear a being illustrated by way of example. Any suitable harness motion the sheds maybe provided. In the illustrated construction I have shown a set of harness frames 20 arranged to slide inhorizonta-l ways 21 in the frame a and all assumed to be normally held forward by springs (not shown). the same having rear- Wardly projecting flexible connections 22 which pass around and are secured to conical sheaves 23 ployed, obviously',so as to obtain the desired convergence in the warp shed) whose shafts 2 1 are journaled vertically have cranks 25 which are connected by a suit-able connection 26 (see Fig. 2) with suitable operating means 27 actuated from an eccentric 28 on the tappet shaft 18. The arrangement of the sheaves and the connections 22 is a well known one: that is, the frames 20 are grouped in two sets, and one end of each connection 22 is attached to a frame in one set and the other to a frame in the other set, so that when the sheds are oscillated the sets of frames will be.recipro cated in opposite directions.

Thepresent loom is designed for the operation of two shuttles. At one end of the batten 8 (Fig. 2) is a single box 29. At the other end is a box structure 30 including, in

the present case, two shuttle boxes arranged one above the other, the same sliding vertically in a framing 31 forming an extension af the batten structure.

for forming (conical sheaves being em Box structure 3,0'

has a fixed depending rod 32. Framing 31 has :1 depending bracket- 33 in which are journald iutermeshing bevel gears 31-35, the former of which is connected with-rod 32 by the pitman 36 and the latter of which is confined to move up and down with the bracket by being housed in a bend 533 thereof. Bevel gear 35 is splined on and movable vertically of a. rotary shaft 3? which is journaled in bracket E53 and a fixed bracket 38 on frame a, said shaft having no vertical movement and being connected with a horizontal shaft 39 by bevel gearing -10, and shaft 39 being connected with the tappet shaft by bevel gearing 41 (see Fig. 3). The construction is such that due to the extensibleconnection (pe'rmittedby the spline between 35 and 37) between the tappet shaft and the box structure 30 the box wardly, so that'lever 13 moves a sprlngpressed dagger 45 out of position, when the through a. spring elevated rod 47 oscillate a lever 48 for imparting a thrust to a suitably guided rod 49 which impinges the control lever a to'shift the same and stop the loom; obviously, if theshuttle fails to box properly lever t3 will not actuate the dagger and so the loom will be stopped.

The general operation is quite similar to that of ordinary looms. Gearing a-19 being -1 to 2 and the tappets 17 diametrically in the frame and oppositely arranged on shaft. 18, the pickers (first one and then the other) are actuated on every reciprocation of the batten structure, while thetwo sets of harness assume their limits of movement, one forward and the other'back, on every such reciprocation,

thus to form'the sheds, because eccentric 28 is arranged on shaft 18, which performs a half revolution to every full revolution of shaft y. Every time a shuttle is thrown across the loom from its box in structure 30 and back again said structure is shifted up or down from shaft 18, it being noted that the gear ofigearing 411 which is on the shaft 18 has all but a few of its teeth absent.
