SPECIEICATON forming` part of Letters Patent No. 662,71*?, dated November 27. 1900. Application filed February 9, 1900. Serial No. 4,608. (No model.)

To if/ZZ whom it' may conoerw Be it known that I, WILLIAM V. GEE, acitig zen of the United States, residing in Philadele phia, in the county of lhiladelphiaJ and State of Pennsylvania, have invented certain new and useful Improvements in Needle-Loomsg and I do hereby declare the following to be a full, clear, and exact description of the iuvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates to looms, and it has re ference particularly to the class of such m aA chines known as needle-looms.

Theinvention consistsin theimproved needle-loom and in thecombination and arrangements of its several parts and groups of mechanisms, substantially as will be hereinafter pointed out and finally embodied in the clauses of the claim.

I have fully illustrated my invention in the accompanying drawings, where the improvements are represented as applied to a narrowware loom, though they are as well adapted to a loom of the broad-goods type.

In said drawings, Figure l is a view of one end of my improved loom. Fig. 2 is au enlarged View of a portion of the other end thereof. Fig. 3 is a horizontal sectional view taken in a plane slightly above that of the warp. Fig. 4: is a view in front elevation of that portion of the loom which includes the hatten and accessory mechanism. Eig. 5 is a top plan View, slightly enlarged, of a portion of what is shown in Fig. 4. Fig. 6 is a view in front elevation of the belt-shifting mechanism, showing a portion of a certain au- Figs. 7, 8, and 9 show the relative positions of the needles at various stages of their operation. Eig. l0 is a detail view of one of the fillercarrying needles; and Eig. il is a perspective View of the shed and the two sets of needles, showing the manner in which the loops are formed in the iiller.

@indicates themain frame of the loom, comprisingjn its structure uprights l), which are connected by a series of horizontal beams c, d, e, and j".

g designates the main drive-shaft of the loom, the same being journaled in brackets 7L on the uprights b. On one end of this shaft is secured a gear t', with 4which meshes a pinion j, which is journaled on a stub-shaft 7c, projecting from the end upright l). The stubshaft 'lo carries two pulleys Z., the one of which is fast while the other is loose on said shaft. m designates brackets which project from said end upright band in whichis fulcrumed a beltshifting fork n, whose bifurcated end extends opposite to said pulleys, while its otherend is controlled by a spiral spring o, connecting it with a projection of said bracket. p is a pawl pivoted to the upright and adapted to engage a pin q ou the fork to maintain the latter opposite the fast pulley, which is the one next to the frame. On the otherend of the shaft gis securedafly-wheel r, said [ly-wheel and the gear t' being adapted to reciprocate the lay-swords s of the loom, said lay-swords being fulcru med at theirlowerends in the uprights of the loomframe and being connected to said gear and fly-wheel through the medium of pitmen t. The lay-swords s carry a hatten u, to the front face of which is secured, the one above the other, a pair of bars o, said bars having longitudinal slots w, through which project screws or pins an, whose heads keep the barsin place, the latter th us being free to reciprocate longitudinally of the hatten. In one end of the batten is journaled a short shaft y, which carries at one of its ends a lever z, secured at about its center to said shaft and pivotallyconnected to the bars o through the mediuin of connectingrods Z. The other end of the shafty carries a bevel-pinion 2, with the teeth of which intermesh the teeth of another bevelpinion 3, mounted on a rock-shaft 4, that has bearings in a bracket 5, secured to the back of the end portion of the hatten. The shaft 4 carries an arm 6, rigidly secured thereto and provided with a pin 7, engaging a slot 8 in a lever 9, said lever being fulcrumed in a bracket 10, suspended from a portion of the adjoining end frame of the loom. 'lhe pin 7 is arranged in a slot ll of the arm, so as to be adjusted therein.

The lever 9 is actuated IOO -the same plane.

springs 36.

from the shaft g through Vthe medium of a slotted cam 12, secured on said shaft, its slot being engaged by a pin on the lever. It will be observed that the connection between the arm 6 and the lever Which is afforded in the slot 8 and pin 7 is provided so that the batten may swing unobstructed by said lever, the connection at the same time being such a one that the movements of the lever are effectively transmitted to the arm.

13 is a horizontal bar Which is sustained above the batteri u by means of uprights 14 and pairs of Vertical strips l5. The reeds 16 are secured in position between the members of these several pairs of strips, as shown in Fig. 4 or Fig. 5. The upper surface of this bar is provided with a longitudinal slot 17, and in said slot is arranged in proxiniityto and each side of each reed a small pulley 18. The weft-thread or filler is taken from bobbins 19, arranged on the beam d, through pairs of openings 20, disposed in the bar intermediate the reeds, and thence extending 'the oneinone direction and the other in the other direction over the pulley 18 and thence downwardly throughoriccs 2l in said bar to the filler-carrying needles. Said needles are designated by the reference character22, and, as seen in Fig. 10, they consist of an I -shaped piece of metal secured to the bars o, with their shank portions 23 extending those on one bar inY one direction and those on the other bar in the other direction, but all in Each needle has two eyes, the one, 24, at the rear endof its shank and extending horizontally and the other, 25, at the forward end of its shank and extending vertically. The thread extends first through the eye 24 and then through the eye 25.

`Between the openings 20 and the pulleys 18 cach filler or weft-thread extends over a seriesof pins 26, bridging the slot in the bar -'orked lever 28, lwhich is fulcrumed upon a bracket 29, projecting rearwardly from the bar, and the adjustment ot' which may beeflfected bya weight 30, which its'free-end car- Each forked lever and series of pinsY ries. together constitute a tension device for the thread.

Between each tension device and the orifice each weft-thread extends over the corresponding rod 31, being adapted to'be engaged by a projection 33. The action which the rods 31 is adapted to exert upon the liller willbe Ahereinafter explained.

In order lto stop the Working of the loom should athreadbreak, I have provided a series of push-rods 34, mounted in brackets 35, which the beam ccarries,and actuated by The inner end of each push-rod is provided with an enlargement or head 37, being adapted to be engaged by the adjoining forked lever 28 in case the corresponding which pins 53 '54 on the levers engage.

thread should break, while the outer or free end of said push-rod is adapted to engage the enlarged end 38 of one of a series of arms 39, projecting from a rock-shaft 40, Which is journaled in brackets 41, mounted on the beam c. A crank 42 on the end of the shaft 40 is connected to the pawl p, above described, through the medium of a cord or other flexible connection 43, passing over suitably-arranged pulleys 44.

The beams CZ and c are connected by a series of parallel plates 45, arranged opposite the several reeds, and resting on said plates and adapted to reciprocate thereon are carriages 46, each carriage having longitudinal slots 47, penetrated by pins 48, mounted in the corresponding plate, so as to vbe guided on said plate. The several carriages'arefcon- Anected :togetherby means of a transverselyextending strip 49, which lhas a slot-and-pin connection 50'with the upper ends-of levers '51, that are itulcrumed in the end uprights b ofthe loom-frame. These levers are vibrated by means of slotted cams 52, with the slots of To the forward end of each carriage is adjustably secured a paiiI ot' small plates 55, and upon these plates is Iin turn adjustably secured a pair of blocks 56. In said blocks are fulcrumed the rear ends of the looping-nee-v dles57. Eachlooping-needleis perfectlyflat, as best shown in Fig. ll, and itis provided near its middle portion with an upwardlyextending spur or hook 58. The needle extends through the reed, preferably between the second and third dents lthereof, (there being, of course, vtwo of these needles, one at each side of the reed and arranged to-correspond and coperate with the filler-carrying needles,) and its free end is maintained for Any suitableI let-o mechanism 65 may be employed. That which vI have shown in the accompanying drawings is a let-off mechanism of the construction patented to Otto `W. Schaum under Letters'Patent No. 625,206, of May 16, 1899. Likewise anysuitable take-up mechanism is employed. The take-up mechanism shown in the drawings consists of a beam 66, upon which the cloth is wound and which is -rotated by a train of gearing 67,

Vcontrolled by a ratchet 68, which is in turn actuatedv by one of the lay-swords 69 through Ithe medium of a pitman 70 and an arm 71,

IIO

The operation of the loom is as follows: As shown in the drawings, the hatten is in its forward position, thereeds havingjust beaten up the weft. Just before the beating-up occurred the looping-needles withdrew, releasing the loops which they had coacted, with the filler-carrying needles, to form. As the batten recedes, therefore, so do the loopingneedles, the latter, however, keeping slightly in advance in the receding movement of the former. Vhen the batten has reached its rearward position, then the filler-carrying needles enter the sheds, which have meantime been formed in the several warps by the harness 72, and as they approach the limits ot their advanced movements the spurs of the looping-needles (which now move forward, again beginning the return movement ahead of the hatten) are projected through the reeds, coacting with said ller-carrying needles to produce the loops in the manner seen in Fig. ll. Having looped the threads on the spurs of the looping needles, the other needles quickly withdraw from the sheds under the actuation of the oscillatoryleverz. The action of the filler-carrying needles consists of intermittent and properly-timed thrusts occurring, as stated, at the time when the batten is retracted. The batten now begins again to move forward. Simultaneously, of course, as the batten advances the looping-needles advance, keepingalittle ahead of the former until just before the time for the reeds to beat up the loops maintained by said needles, whereupon the latter again begin their return movement, the consequent movement of the reeds and looping-needles in relatively opposite directions resulting in slipping the loops off the spurs of the latter. The action of the looping-needles so that they may properly coact with the hatten and the filler-carrying needles is of course dependent upon the shape of the cams 52, which actuare said needles through the medium of the levers 5l, the bar 49, and the reciprocatory carriages 4 6, upon which said needles are mounted. As fast as the goods is produced it is of course wound on the take-up roller 66 by the action of the take-up mechanism, which, like the let-off mechanism, is being` meanwhile actuated. The crossing of the warp-threads in changing the sheds occurs between the time when each beating up is effected and the time when the needles 22 begin to again carry the filler through the sheds and the loops are formed ltherein. The needles 22 draw off from the bobbins the necessary amount of filler each time they retract. This is because in their rest positions-t. e., that shown in Fig. l-their eyes 24 are farthest from the orifices 2l in the bar 13. The illertakeu off is maintained taut by the coacting forked levers 28 and pins 26. However, should a thread break, the next time the hatten swings back the corresponding forked lever will drop and engage the interposed push-rod 34, effecting the shifting of the driving-belt in the manner set forth. The looping-needles being disposed so as to penetrate the reeds two or three dents from the side edges of each of them, it will be seen upon a view of Fig. ll that when the shed is open the looping-needles each extend between two ot' the correspondi ng th reads near the edges of the warps, the spurs of said needles being in the openings formed by the sheds. Now as each spur 58 has appreciable vertical thickness, when the looping-needle retracts, since the latter is close to the edge of the warp, the extreme end portion of the loop is left protruding from the goods after the loop has been beaten up. The series of these extreme projecting portions of the loop is what goes to make up the selvage of the goods.

In order to insure eveuness and uniformity in ihe selvage, the rods 3l, which have been already described, exert pulls upon the threads, so as to withdraw from the shed the superfluous portion of the filler.

If desired, of course, the shifting-fork may be operated manually, in which case the rockshaft 73, which carries said fork at one of its ends, may carry a vertically-extending lever 74 at the other of its ends, to which is connected a sliding rod 75, movable in brackets 76, mounted in the front portion of the loom.
