NEEDLE-Loon.

To all whom it mary concern:

Be it known that I, CHARLES J. NAUEN, a subject of the EmI-peror of Germany residirg in Paterson, assaic county, and State o New Jersey, have invented certain new 4and useful Improvements in Needle-Looms; and I do hereby declare the following to be a' full, clear, and exact description of the invention, suchaswill enable others skilled view ofwhat'appear's in-Fig.

. form which, through the 50 in the art to which it appertains to make and use the saine, reference being had to the accompanyip drawings, and to letters -of reference mar ed thereon, which form a part .ofgthis specification.

This invention relates to looms lof the s0- called needle loom type and it consists in certain improvements therein having for their objects to simplify the construction and render the operations involved more certain and uniform and, in' general, to provide a loom in which' an improved quality of fabric may be woven without vincreasing the cost of manufacture. The invention 'wil be found ully illustrated in the accompanying drawings, when. i w v j Figure 1 is aside elevation of sucient of the improved loom to illustrate the present invention; Fig. 2 is a front elevation of the hatten structure and accessory mechanism; Fig. 3' is a vertical sectional View of the -batten structure and accessory mechanism ona somewhat larger scale; Fig. 4 is a plan 3, certain parts appearing in section; Figs. 5 and 6 are detai' views of the means n said drawings I have shown my invert.;4 tion applied to a loom of the narrow-ware ty e, that is, a loom .in which a plurality of fa ries are woven at the same time; it will be understood, however, that m invention may be applied to looms of t which broad lfabrics are woven.

Set in the top of. the hatten is a bai' longitudinally thereo One end of this bar has an opening lc covered by a late of leather or the like Z having an ori ce m to receive the upper end of the picker-stick n fulcrumed in in the usual manner; the leather plate Z serves to deaden the shock of the pickerstick, reducing the noise and vibration incident thereto. To the back of the hatten nected by a rod g having the bearing-pieces Ir in which slides, parallel with the bar y', a bars. To the bar 8,'at the end thereof opposite that adjoining the picker-stick ln, is secured a block t having an orifice u which receives the upper end of a picker-stick o fulcrumed in the batteri structure. The block t is formed of leather so as to deaden ythe shock of the picker-stick. The late Z and the block t are secured'to the ars j and s by screws Z' and t' so that eachjmay or left as the conditions may require. e picker-sticks are each normally drawn outwardly by the spring o in the usual manner. To the back of the .hatten is secured at each weaving space a channeled rest w for the reed a: which 1s held at the top, in the usual manner, by a clig y pivoted tothe rod q.

t suitable intervals, corresponding to the lcenter-to-center distance between each two weaving spaces, u wardly projecting arms e are securedto t e bar j, the same in their upper ends (which are the oint of each'needle being projected toward the ileft and being' rovided with an eyelet 2 of porcelain or t e like; the eyelet-carrying part of the needle is .preferably a separable piece having a lap-joint connectowhich it is se- 3, so that it may be rethe eyelet or any simi- At similar intervals downwardly pro]ecting arms 4 are secured to the bars, and in the lower ends of these arms, in a plane slightly above the needles 1, are secured the needles 5, the same being identical in construction. with the needles 1 and pro'ectin from the arms 4 to the right. When t e pic er-sticks occupy the positions cured b the screw moved or renewin lar purpose, (Fig.

the harness controlling the he hatten p which are conshownin Fig.' 2 all the needles 1 stand at the right and all the needles at the left of the corresponding weaving spaces. The arms 4 are secured on the bar s by sctscrews 6 so as to be adjustable on the bar (which is round in cross-section) forward and back to bring the needles in the desired relation to the needles 1.

The filling is supplied from a series of bobbins 7 carried by a support 8 beneath the batten. The fillino from each bobbin passes upwardly there rom through a tenl only being shown) g 7 17 carrying cranks 'of a Weaving space.

s1ondevice 9, carried by the rail 10, and then through a' vertical tube 11 penetrating the batten vertically at the back thereof, through the eyelet 2` of one of the needles (1, 5) to the cloth'. rlhe tension device 9 comprises a fixed member 12 and a pivoted member 13 having alternating eyelets 14 throu h which the iilling passes zig zag fashion, te member 12 being held normally in the position shown by a spring 15.

In bearings 16 secured to the front upper edge of the batten is journaled a rock-shaft 18 Xed thereto so as to be rotatably adjustable thereon by the setscrews 19 each crank being immediately to the right of a weaving space) and also carrying cranks 2O which are pivotally movable thereon, being disposed between collars 21 and standing each immediately to the left Each crank 18 (20) carries an adjustable arm 22 (22) which projects rearwardly over the batten its rear or free end is adjustably supported by the screw 23 an upright loop-holding needle 24 (24).

Below the crank crank-shaft through the transmission gearing 26. Tappet-cams 27 set oppositelyto each other (and only one ofA which is shown) are arranged on this shaft and operate to depress alternately the levers 28 which are connected with the picker-sticks by the straps 29 extending over pulleys 30 arranged on the hatten; the springs 0,.which/Y normally hold the picker-sticks in their outtend to raise the levers,

wa'rd positions, which have sudden downward impulses imparted to them by thev tappeti cams resulting in quick movements of thepicker-sticks inwardly land outwardly and consequently of the needles l and also fixed the reversely set cams 31 (one each of these cams has one-half (approximately) of its periphery semi-circular, as at 32, half includes a sudden centric portion 34 and in the order named in the direction of rotation of the cam as indicated by the arrow in Fig. l. Against each of these cams an anti-friction roller 36 on one of two levers 37 is held by a spring cranks 20 by and in shaft is journaled a,

vshaft 25, the same being rotated from the, i"needles 24.

5." On the shaft 25 are` the sets of needles 24 or 24 and slowly falls, the alternating movements referred to being due to the while the remainingf-'ftion of the cams 27 to each-other and cams depression 33,` a cona rise 35 following 38"`conn'ect`ing the lel ceases The mais is and 2o caused to oscillate reversely, the motion being transmitted'V from the levers 37 as follows: At one end the rock-shaft 17 carries a rearwardly projecting arm 39 which is connected with the adjoining lever 37 by the adjustable pitman 40. lIn bearings-41 another rock-shaft 42 is journaled belowthe rock-shaft 17 and this rock-shaft carries cranks 43 which are connected, with the the links 44; at its right-hand end this rock-shaft,carries a rearwardly projecting arm 45 which is connected with the` corresponding lever 37 by the adjustable pit-man 46. It is preferable to 'limit'the upward movement of the arms 39 and 45 under the action of the springs 38 by stops 47 secured to the hatten.

Operation: The hatten is reciprocated in the usual manner from the crank-shaft d, the reed beating up the filling upon each forward movement of the hatten and the shed opening thereof. On' each Vbackward /movement of the batten.that is to say, while the shed is open, one or the other of the sets of needles carrying the` llling (designated A) moves backI and forth. through the sheds, the movements of the two sets of needles alternating.

on each backward movementn Respecting either set of needles l and ,n'as it reaches the limit of its movement into the,shed the set of needles 24 (or 24) disposed at the relatively opposite sides of the fabrics Vis raised by a quick movement to catch the filling and', on the receding of the needles 1 or 5, oacts therewith to form the. loops, the set of (or 24) receding (descending) slowly so as toclearthe loops which they are holding at' about the time the hatten advances to beat up the filling at the fell of the cloth. It willl be understood, in Vview of the foregoing, that the sets of needles 24 and 24 alternately performntheir up'and down movements, so as to coactwith the alternately moving sets of needles l and 5.. To this end the shaft 25 rotates at one-half of the speed of the shaft d, the result of which is that every other time the .hatten moves back one or the otler of the sets 'of needles 1 and 5 moves into-and out of the sheds and that, during every other cycle of movement of the batten, one or the other of quickly rises opposite relaneedles 25, occurring asthe camand this dwell being followed by the slow downward movement of the needles 24 (or 24'), due to the,

spiral Having tion, what I claim'as new cure by Letters Patent is:

1. In a needle loom, the combination of the frame, the batten, two .filling carrying needles, oppositely movable separate supporting members for said needles each movable longitudinally right loop-holdin needles respectively coacting with the fil ing carryin needles, separate supportin members or the loopholding needles ]0urnaled on the same axis parallell with the paths of movement of the needle supporting members, vmeans for recprocating the batten, means for alternately thelling carrying needles and means for alternately oscillatln the supporting members for the loop-ho ding needles, substantiallyI as described.

2. In a' loom, the combination of the of the batten, two upsupporting members for frame, thel batten, filling carrying needles, two oppositely movable separate sup orting. members for said needles each mora le longitudinally of the batten, two upright loopholding needles respectively coacting with the lling carrying needles, a rock-shaft journaied in the batten parallel with the paths of movementv of said supporting members, a crank journaled on said sha t,' supporting members for the loop-holding needies respectively carrie by the rock-shaft and crank, means for reciprocating the batten, means for alternately reciprocating `the supporting members for the filling carrylng needles and means for alternately oscillating the rock-shaft and said crank, substantially as described.

In testimony, that I claim the foregoing I have hereunto set my hand this 8th day oi' September, 1910.
