WIRE LOOM.

lApplication filed August 17, 1923. Serial No. 857,926.

This invention relates to looms, and more especially tol looms for the weavingr of fabrics of wire strands, such as window and door screens, and while the present apphcation is drawn to a machine for the production of such fabrics, I Wish it understood that the improvements herein disclosed are applicable to machines for producing fabrics of different kinds of material and of different size mesh to be used for other purposes, such, for instance, as heavier wire screens for the separation of sand, gravel, seeds,

etc., or to produce fabrics formed of fibrousstrands, such as cotton screening, uetc,

One object is to rovide means, 1n such a machine, whereby t e maximum uniformity of spacing between the weft or filler wires or threads isobtained by the timed co-operative action ofthe heddles, the shuttle transferring bars and the reed to place the weft wires at the lay of the completed fabric in exact spaced intervals during the constant, uniform, longitudinal movement of the warp wires or threads. V i

Another object is to provide tensioning means for automatically exerting a constant and uniform strain or tension on the War wires while permitting the alternate uA an down movement of 'the same, lthrong 1 the action of the heddle frames, with a minimum danger of breakage of said wires, said /mea'ns serving also 'to provide compensating 'means to' intermittently drive the take-up roll for the completed fabric, since the effective diameter of the roll of fabric is ever increasing and`the woven fabric is fed forward at a regular rate of speed, the take up of said fabric is done at intervals, after a predetermined amount of excess has been woven the automatic compensating means being' then automatically re-set for continued weavingr ofthe fabric;

A further object is to provide means in a loom of this character, for easily and quickly changing certain gears to provide for l the necessary rate of speed of travel of the warp wires in weaving' different kinds and different size mesh fabrics;

A still further object is to provide means for accurately alining the shuttle transfer bars in exact longitudinal alinement with each other and transversely of the machine,

so that the said shuttle may be readily re' leased by one bar and received by the other during its transit through the shed formed by the warp wires, in their alternate up and dov-vn movement through the action of the heddle frames, which in the present invention are positively driven by cranks and pitrnen and caused to uniformly travel in rigid guides in the frame of the machine.

A still further object is to provide means for enabling the operator to manuali opcrate the take-up mechanism when it 1s desired to Wind up some of said excess fabric -on the take-up roll or to unwind the same as when an inspection 1s necessary and also to provide means for manually shifting the drive belt from the loose pulley to the drive pulley or vice versa.

A final object is to provide means for automatically stopping the action of the 100m by the shifting of the drive belt from a drive pulley to a loose pulley, in the event one or more of the strand or Warp wires breaks (as when the loom is engaged in weavingr wire fabric), said belt being readily shifted again back to the drive pulley by the hand of the operator, when the said Wire or wires have been again joined together and the weaving operation is continued.

,A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection with the accompanying drawings formingr a part of this specification; it being understood that while the drawings show a practical form of the invention, the latter is not to be confined to strict conformity with the showing thereof, but may be changed or modified, so long as such changes or modifications mark no material departure from the salient features of the invention, as specifically pointed out in the appended claims.

The machine comprises a right and a left hand frame member, l and 2,1respectively, formed of suitable cast metal and similar in construction, as to the main features, each member comprising a lower, longitudinal sill 3 arranged horizontally and in spaced relation to the floor or support, an intermediate, horizontal sill 4 and a top, horizontal sill 5, said sills being joined together by a. vertical front post or standard 6, an intermediate Vertical standard 7, extending above the topsill 5, as at 73,@ and a rear vertical standard 8, the several sills and posts being preferably formed integrally and provided with the usual marginal strengthening beads or flanges generally used in such structures.'

The lower ends of the several posts extend below the lower sill and are provided with outstanding feet for bolting the machine frame to the floor, and the two frame members are spaced apart a. distance to accommodate the maximum width of fabric to be Woven, suitable tie rods being connected to the said members to rigidly maintain the same in proper spaced and parallel relation to each other, such tie rods being located at convenient points where the -same will not interfere with the operation of the component parts of the loom.

Each rear standard 8 of the .frame mem.-

bers

1 and 2 is 'rovided with a seat 9 for the recept-ion of alliearing bracket 10, which is suitably bolted thereto and is adapted to` receive the adjacent end of a drum shaft 11, the said shaft being rotatably held in said bearings by detachable bearing caps 12, which may be easily and quickly removed in order to lift the shaft from the supporting brackets.

Mount-ed on the shaft 11 is a strand wire or warp wire drum 13 comprisingend heads or spiders 14 of Wheelelike formation and so located .and secured to the shaft as to lie immediately within the side frames 1 and 2 and adjacent to the inner faces of the same.4

The spiders 14- have peripheral rims 15 formed in a plurality of i'lat faces for the receptionof wooden planks 16, whose outer faces are formed in the are of a circle, and

which, when suitably secured to said rims form a complete, circular drum around the outer surface of which is secured a cylinder 17 of sheet metal to form a hard, smooth surface about which the said strand wires are wrapped. y

Adjarentto each end, the drum 13 is provided With a series of longitudinally alined apertures or sockets 18 'formed through the sheet metal cylinder and the planks, and around the drums are placed a pair of flanged rings 19 having an internal diameter to freely slide thereon, and which are held in adjusted relation to the ends of the drum` and in proper spaced relation to each other, by means of screws or bolts 20, which may be screwed into any pair of diametrieally opposite apertures 18 to hold the rings 19 in such adjusted position as to confine the strand wires therebetween in suitable numbers to accord with the width of the fabric being woven, all of which may be readily understood by reference to Figures 29 and 30.

The spider 14 located at the right hand side of the machine has its spokes extended radially beyond the drinn 13 and carry an integral spur gear wheel 21, of relatively large diameter, which meshes, at all times,

lwith a relatively small pinion 22 located within the frame and carried by a stud shaft 23 mounted in a suitable bearing formed in the inclined frame bar 24 which connertsthe intermediate, horizontal sill 4 to the top horizontal sill 5 in the right hand frame member 1.

Mounted on the stud shaft 23, and adjateryt to the outer face of the inclined frame bai 24, is a worm wheel 25 of larger dialneter than the pinion22, the worm wheel and the pinion being each keyed or otherwise secured to the stud shaft 23. so that when power is imparted to the said worm wheel, the pinion is consequently rotated to impart a relatively slow rotary motion to the druln 13 by reason of the great difference in the diameters of the meshing gears.

`The worm wheel 25 is actuated by a worm 26 located beneath the same, and mounted on a longitudinally disposed drive-shaft 27 located on the outer side of the right hand frame member 1, and having its rear end portion mounted in spaced bearings 28 located at the ends of the worm 26 and suitably bolted to` the intermediate, horizontal sill 4, adjacent to the rear end thereof. said bearings preferably having their removable caps formed integrally with an oil pan 29, which surrounds the lower half of the worm 26 and is adapted to be filled with oil, in which said 'worm revolves for the purpose of lubricating the connection between the worm and the worm wheel. (Refer to Figures 1 and 5.)

The forward end of the shaft 27 extends through and beyond a bearing 30 secured to 3 1 mounted on the shaft at the ends of the worm 26. which is keyed to said shaft, and between thc said bearings 28, serve to prevent any longitudinal movement of the main drive shaft 27 in its several bearings.

The shaft 27 carries a spline 32 at a point intermediate of the front bearing 28 and the bearing 3x0, and interlocked with said spline and mounted on the shaft 27 is a slidable bevelled pinion 33 adapted to be thrown into and out of mesh with another bevelled pinion 34` which is carried by and adapted to rotate with a stud shaft 35 suitably mounted in a bearing in the intermediate, horizontal sill 4, and at right angles to the drive shaft 27.

At the inner side of the sill 4, the stud shaft carries lan interchangeable spur gear 36 which is adapted to receive power from an adjustable idler gear 37 for imparting motion to the ydrum 13 through the bevelled pinions 34 and 33, the shaft 27, worm 26. worm wheel 25, spur pinion 22 and spur gear 21.

The adjustable idler gear 37 is rotatably mounted at the lower end of a depending arm 3S of a bell-crank lever, which is ful- (rumed at its elbow portion upon a transverse shaft 39 which extends entirely across the machine, and has its end portions mounted in suitable bearings in the upper portions of the inclined frame bars 24 in each of the

frame members

1 and 2, the said shaft being adapted to revolve in its bearings indepcndcntly of the said bell crank lever hav' ing the depending arm 38. (Figures 1, 10 and 11.)

The other arm 40 of the bell crank extends forwardly and overlaps t-he intermediate standard 7 at the right hand side of the machine, and is provided at its free forward end with an arcuate shaped head 41 having a longitudinally disposed, arcuate slot 42 formed on the are of a circle, having its center' at the axis of the supporting shaft 39. and adapted to receive a binding tbolt 43 screwed into the inner face of the intermediate standard 7 of the right hand frame member 1 to hold the bell crank lever in any desired adjustment for a purpose to be explained. l

Mounted on and `keyed or otherwise se` cured to the shaft 39 is a spur pinion44 which meshes with and is adapted to drive the pinion 37, and these two pinions are preferably of substantially the same diameter while the interchangeable pinion 36 may be of different sizes according to the size and kind of mesh being imparted to the woveirfabric, as for instance, when it is desired to decrease the speed of the drum 13, as when weaving a finer mesh, at which time the strand or warp wires must be fed more slowly, the spur gear 36 may be removed trom the stud shaft 35, and a larger spur gear wheel'ia (asillustrated in Figure 10pt the drawings)v may be substituted therefor, which will result in a slower rotary movement of said drum 13. ln order to make such change, the binding bolt 43 must be loosenedv and the bell crank klever rocked upwardlyabout its fulcrum on the shaft 39, at which time the adjustable idler gear 37, which will remain in mesh with the gear 44, may be suitably meshed with .the teeth'of the larger wheel 36a. By a similar operation the gear 36 may be replaced by a smaller gear for increasing the speed of rotation of lthe drum 13, at which time the bell crank lever will be lowered, as will be readily understood.

The shaft 39 extends beyond the bearing formed in the inclined frame bar 24 at each side of the machine, and where extending throughthe frame member 2 ,at the left hand side, a drive gear 45 is mounted which, as shown in Figure 2 of the drawings, is-in mesh with another gear Wheel 46 of conslderably smaller diameter, and carried on the projecting end portion of another transverse shaft 47 arranged directly over the shaft 39 and mounted in bearings secured to the upper surface of the longitudinal' upper sills 5 of each frame member.

Outside of the sill 5 of the right hand frame member l, the shaft 47 carries a gear wheel l48, which is of the same diameter as the wheel 45, and which, in turn, meshes with a relatively small idler gear wheel 49 adjustably mounted in an upward extension of the right hand trame member 1, and which meshesI with another spur pinion, coI1- stituting a drive pinion 50 secured to a Vdrive pulley 51 and mounted o'n a stud shaft 52, there being a loose pulley 53 immediately adjacent to said drive pulley.

lThe idler 49 is rotatably mounted on an adjustable stud 53", which is held in adjusted position by a binding nut 531 in an arcuate yslot 54 formed in tbe aforesaid upward extension 55 of the right hand frame member. rllhe slot 54 is formed on the -arc et a circle whose center is the axis of the shaft 47` so that the ratio ofthe drive gear wheel 50 and the idler 49 may be change-d and the meshing connection still maintained to produce therequired timing of the drum 13. The stud shaft 52 is also suitably mounted in the upper portion of the upward extension 55, and suitable provision made to render the same rigid and strong to withstand the strain of the drive belt 56.

llben, as is sometimes necessary, it is desired lto stop 'the rotation of the drum 13 without shitting the belt and stopping the retrasar operation of the entire machine, a toot pedal 57 located at the forward end of the right hand trame member is located in position to be pressed by the rightoot of the operator, (Figure l) said pedal being normally elevated and extending back along the side of the machine frame where it is fulcrumed at an intermediate point upon a pivot post 58, the rearwardly ext-.ending portion of the pedal carrying a weight 59, which maintains the foot portion of the pedal in elevated position. An upstanding arm 60 is formed integrally with the pedal bar, and is bent outwardly for connection to a pull rod 6l, which extends rearwardly and upwardly, the rear end of the same being in turn pivotally connected to lthe intermediate portion of a shifting yoke arm 62, whose lower end is fulcrumed upon an outstandingpin or bolt 63 mounted at the lower edge of the lower sill 3 of the right hand trame member, and substan-` tially beneath the slidable, bevelled pinion 33. The shitting yoke arm 62 is provided at its upper end with a yoke 64, having .inwardly directed, opposed pins fitting into an annular groove 65 formed in the 'hub of the bevelled pinion 33, so that when the pedal 57 is depressed, the said bevelled pinion 33- is forced forwardly along the spline 32 of the shaft 27 (Figures 1 and 5) and since the said pinion meshes with the coacting pinion 34 at the front portion thereof, the connection between the two pinions is broken, and the train of gearing between the pinion 34 and the drum 13 remain inac-I tive. TWhen the 'foot of the operator is re moved from the pedal 57, the weight 59 immediately throws the said pinions into mesh again, for a continuation of the drive( or' the drum 13.

Since the strand or warp wires are continually rolling oft' the drum 13 during the operation of the machine and the same are threaded through the various working parts of the loom in a manner to be later described', some provision must be made to take up the woven fabric and to maintain the said wires in a taut condition, such means including means tor allowing a ortion of the said fabric to be woven an while still maintained in a taut condition, toaccumulate to aeertain amount before being wound on the final take-up roll. The latter feature compensates for t-he ever-increasing diameter of the roll of completed fabric.

In order to accomplish this desired result, there is provided a front extension shaft 66 mounted at the right hand side of the machine and in exact longitudinal alinement with the shaft 27, (Figure 5) the same being mounted in spaced bearings 67-67 secured to the trame member 1 adjacent to the front end thereof and preferably termed integrally, as in the case ot the rear bearings 28, and

llt)

lltlll provided with the same kind of a an 68 for containing a quantity of oil, in w ich there is adapted to revolve a worm 69 secured to the shaft 66, and spaced from the bearings 67 by collars'70, which prevent any longitudinal movement of the shaft 66 through said bearings.

The rear end of the shaft 66 abuts against the front end of the main shaft 27, and is adapted to be intermittently rotated in unison therewith by means of a toothed clutch member 71, keyed or otherwise secured to the rear or abutting end of the front shaft 66, and into which there is adapted to be slid a corresponding clutch collar or member 72 having intertitting teeth for the purpose, and provided with an annular groove 73 for the reception of inwardly directed, opposed pins of a shifting yoke 74 pivotally mounted, at its lower end, upon a in 75 secured in the upper end of an upstan ing post 76, preferably formed integrali on the upper edge of the lower sill 3 in a Vance of the intermediate standard 7.l

When the shifting yoke 74 is rocked in a forward direction, by means yet to be described, the clutch member or collar 72, which is caused to rotate with the shaft 27 by means of a spline 77, is forced into meshing relation with the clutch member 71 and power is transmitted to the shaft 66, which causes the rotation of the worm 69, and the latter, which is in mesh with a relatively large worm wheel 78 located over the same and mounted on a drum shaft 79, in turn causes the latter to rotate Whenever the aforesaid clutch members are in engagement.

The drum shaft 79 extends entirely across the machine and is mounted in suitable bearings 89 secured to each

frame member

1 and 2, and said shaft is provided with a drum 81 constituting the take-up drum for retrieving the woven fabric as the same comes from the tensioning device about to be described,

the said. shaft, together with the take-up` drinn 8l being realdily removable from the bearings when the said drum has had a full roll of the completed fabric wound thereon and an empty drum may then be placed in position for further operations. (Figures 8 and 9.)

As the takeup drum 81 is designed to be rotated at intervals corresponding tol ythe length of time it takes to weave a predetermined length or amount of fabric', in order that the said amount may be rolled or wound upon the same, which has an ever increasing diameter, some means must be provided for automatically throwing the clutch members 71 and 7 2 into connection to cause the drum to take up the fabric and in like manner, to throw out the clutch to stop the winding action of the drum when the said amount of fabric has been taken up, during all of which time, the fabric must be maintained in a taut condition.

This is accomplished by means of a tension roll 82 located transversely between the front standards 6 of the frame members and around which a depending, loop portion of the woven 'fabric is passed beneath the same and then passed upwardly and over the take up drum 81, so that the said roll 82, which .is adapted to move up and down, keeps the aforesaid excess amount of woven fabric taut, as the same is being woven and taken from the lay of the loom, and as it is being wound upon the drum 81. Reference is made especially to Figures 6, 7, 8 and 9.

The tension roll 82 is rotatably mounted at its ends in vertically-movable brackets or frames 83 having Haring lower portions provided with ledges or supports 84 for a plurality of weights 85, preferably formed of cast iron and provided with end extensions 86 to rest upon said led cs 84, the purpose of the separate weights lieing to enable the proper amount of tension to be exerted upon the fabric, as more or less weights may be employed.

The brackets or frames 83 are each provided with upstanding arms 87 suitably aperturcd for the reception of a transverse gear shaft 88, extending across the machine and projecting beyond the said arms for the reception ot' gear wheels 89, located at the inner faces of the front standards, 6 and adapted to mesh with racks 90, which are suitably secured to the inner edges of said front standards. As the tension roll moves upwardly and downwardly the gears at each end thereof cause a uni orm movement, and the tension roll is maintained yin an exact horizontal position at all times with the result that every strand or warp wire in the woven fabric and beyond the lay of the loom receives an equal amount of pull or tension.

In order to steady the vertical movement of the tension roll, together with the end brackets 83 and the weights 85, and to prevent an lateral or longltudinal 'play of the same, tie trunnions 91 of the roll are extended through the bearin portion of the brackets 83, at each end, an there carry rol- 1ers 92 which contact with the vertical side flanges 93 formed on the inner faces of the front standards 6 of each frame member to provide tracks therefor, and to cause the entire tensioning device to move upwardly and downwardly 1n a smooth manner.

As shown in Figures 6 7 and 9, the bracket or frame 83 at thel right hand side of the Inachine is provided with a trunnion 9i, the inn-er portion of which is round in cross section and adapted to receive a roller 95. which also traverses the tracks or flanges 93, and thc outer portion of said trunnion, which is preferably square in cross section, is extended and projects through a vertical slot 96 formed in the front standard 6 of the right hand frame member 1.

A. latch lever 97 is pivoted, at its lower end, on a stud 98 outstanding from the lower portion of the outer face of the right` hand, front standard 6, and said latch lever is extended upwardly and formed into a handle 99 to be grasped by the hand of the operator when it is Ydesired to operate the latch lever manually, as will be later describedu The latch lever is located in front of the projecting trunnion 91, and the lower portion of the saine is widened transversely of the machine and provided on its rear face, adjacent to the outside of the frame member 1, with a rearwardly directed, inclined cam traclr 100, normally lying beneath the projecting end, of the trunnion 911, and adapted to be engaged by the latter, when the tension device is lowered, to cause a forward movement of the latch lever 97 about its pivot 98.

Between the handle 99 and the widened lower portion of the latch lever 97, a slot., 101

is formed, and through said slot the :front terminal portion of a clutch operating lever l102 is eirtended, said lever 102 extending.

rearwardly in a substantially horizontal position, and having its rear end directed inwardly and rigidly connected to a forward- Y ly extending arm 103 forming apart of the Sill l one end to a pin 107- carried by the lever 102,

aforesaid shifting 4yoke 71, which actuates the clutch members 71 and 72 for intermittently driving the takeup drum 81. (Figures 1 and 6.)

The slot 101 is of sufficient height or ei:-

tent to permit the clutch operating lever 102' plane, while the lower face of said lug is forwardly bevelled and normally lies partially across the aforesaid slot 96 in the frame member. (Figures 6 and 7.)

The clutch operating lever 102 is provided with an outstandin pin 105 square in cross section and lying in the pathA of and normally resting upon the lug 10d ofthe latch lever, so that the clutch operating lever 102 will maintain the clutch members 71 and 72 in disengagement, and in order to make such engagement of the lug 104: and pin 105i positive, a coiled spring 106 has connection at and at the other end to a pin 108 outstanding from the latch lever 97, said spring being in an inclined position and tending to hold the lever 102 downwardly and the latch lever 97 rearwardly. v

Secured to the clutch operating lever 102 in rear of the latch lever 97 is an upstanding neaaeev arm 109 having an inturned nose 110jat its upper end, which lies directly opposite the aforesaid slot 96 at the upper end of the latter and in the path of movement of the extended triinnion 9d of the tensioning device.v 70

(Figures 6 and 7.)

'lhe trunnion 9d is apertured adjacent 4to 'its outer end anda vertically disposed pin trunnion 94C also carries a rigidly mounted,

upstanding pin or post 115, the function of which, as well as the purpose and-operation lof vall of these associated parts will soon become apparent. (Figures 6 and 7.) 90' rlhe intermediate standards 7 of each

frame member

1 and 2 is extended upwardly above the top sills 5 and suitably formed for the attachment of the lower ends of upstanding supports 116, which are preferably formed of channel liron and extend above the tops of the frame members, a distance substantially equal to the heights of said frame, the said supports being in perfect alinement transversely of the machine and having their intermediate portions joined together by a suitable frame 117 to brace the saine and prevent any relative lateral movement thereof. (Figures 1 and 3.) The upper ends of the standards 116 are bent forwardl into goose necks 118, the forward` lyexten ing terminals of which are apertured for the reception of a pivot rod 119, the extending terminals of which are adapted to receive the upper'envds of swinging hanger arms "120, preferably formed of suitable cast metal and -provided with niarginal strengthening flanges to render the same stiff and rigid.

'lhe lower ends' of the hangers 120 extendr somewhatbelow the top surfaces of the top sills 5 and are adjacent to the outer faces of the saine, said hangers having forwardly extending brackets 121 provided with vertically disposed bearing eyes, in which are mounted the spindles of horizontally dis, posed rollers 122, which are adaptedl to roll against the outer flat surfaces of arcuate traclrs 123 set into the upper arcuate surfaces of the top horizontal sills -5 'where extending between the intermediate stand-i ards 7 andthe front standards 6. As the swinging hangers 120 are actuated by means about to be described, the rollers 122 will traverse the arcuate traclts 123, which are 130 formed on the arc of a circle having the axis ot the pivot rod 119 as a center, and. prevent any lateral movement. thereotA during the backward and :forward movcmentol the same, said hangers being connected together near their upper ends by a channel iron member 124 and near their lower ends by saaced angle irons 125 which serve to rigidly hold the two hangers together.

Mounted on the extended terminals of the shaft 47, which as betere stated, extends across the machine from frame to frame, are crank arms 126 counterbalanced by weights 126 and which are disposed at the same radial point relative to the axis of the shaft, and the said crank arms are connected to the lower ends of the opposite hanger arms 120, by means of pitmen 127 so that, as the train of gearing 1s actuated, during the operation of the loom, the said hangers are caused to partake of a constant swinging motion to carry the lay of the loom backwardly and forwardly to allow the traverse of the shuttle through the shed of the warp wires and to pack the trans* verse filler or wett wires at the proper, predetermined distance apart.

The upper portions oi the hanger arms 120, which partake of only a slight amount of swinging motion, are provided on their front surfaces with suitable bearings 128, adjacent to the pivot rod 119, for the reception of the outer ends of spaced shafts 129 which are in exact longitudinal alinement with each other, the inner ends of the same being mounted in. spaced bearings 130, (see Figure 3) and extending through the same a suilicient distance for the reception ot inner grooved pulleys 131 which are also spaced somewhat apart.

The outer ends of the separate shafts 129 extend beyond the said bearings 128, where they are provided with other grooved pulleys 132, all of said ulleys being securely keyed or otherwisel astened to the shafts 129 and constituting driving means for the shuttle actuatingr bars, as will be explained.

The outer grooved pulleys 132 are connected by chain lengths 133 to the hooked, upper ends of inclined rods 134 which extend downwardly and rearwardly where they are connected, b adjustable means 135, to the ends of cran arms 136 mounted on the projecting terminals of the aforesaid shaft 39 which extends across the machine. The crank arms 136 are disposed diametrically opposite to each other on the shaft 39., so that the rotation of the Vlatter causes alternate pulls on the two rods and chains at op posite sides ot the machine. (Figures 1 and 3.)

'lhe connecting channel iron 124 near the tops ot the hangers 120 is connected by a vertically-disposed, centrally located plate 137, which has its lower end secured to the upper transverse angle irou,125, and mount- 'ed on said plate at an intermediate pont between the transverse connecting irons 12/1 and 125, is a double groovod pulley 138, one haltl of which is located in front of the plate and the other halt in the rear thereof and joined together so as to rotate in unison in( )either direction. (Figures 1, 3, 1G and 1 The pulleys 138 are connected by short lengths of chain 139 to the aforesaid pulleys 131, the grooves of which are located directly above the peripheries of the grooves in the pulleys 138, as clearly shown in Figure 3 of the drawings. The chains 139 are wrapped around the pulleys 131 inthe same direction, that is, they each fall trom the front sides thereof, and the lower ends ot' said chains are oppositely wrapped about the pulleys 138 at opposite sides of the supportmg plate 137, so that, as one crank arm 136 exerts a pull upon its connected chain 133, the separate shaft 129 actuatedthereby will be rotated in one direction, while the oppo site separate shaft 129 will be correspondingly rotated in an opposite direction through the medium of the pull ot the chain 139 connected thereto, and the action of the double groovcd pulley 138, and when the opposite crank arm 13G pulls its respective chain 133, the opposite movement is imparted to said parts, the wheel 138 travellingsubstantially three-fourths ot' a revolution in each direction.

For the reason that the chains 139 tall from the grooved pulleys 131 in alinelnent with each other transversely of the machine, the double grooved pulleys 138 Inust necessarily be arranged as close together as possible, 1n order that said chains may properly be seated in the grooves ot the latter pulleys which are rotated on an axis at right angles to the upper pulleys, and this necessitates the use ot a relatively thin support in the form of the plate 137. In order to provide ample bearing for the pulleys 138, which would otherwise soon become loose in the bearing under the strain of the alternate pulls of the chains, etc., it is necessary to provide a. specially formed bearing in the said supporting plate, as shown in Figures 15 to 18 inclusive, and described as follows.

The upstanding plate 137 is provided with a round aperture 140, through which there is passed a bushing 141 having an integral outstanding annular flange 142 at one end. This flange abuts against the plate 137 and lreceives an annular locking ring 143 at the other end, said ring bearing against the opposite side of the plate held in osition by rivets 144 passing through alined' apertures in the flange, the plate and the ring respectively, as clearly shown in Figure 18.

One of the grooved pulleys 138 is provided a3 maas/ar With a central, circular recess 14:5 for the reception et the flanged end of the bushing 142, while the other grooved pulley 138 is provided with an annular recess 146 to receive the other end of said bushing together with the retaining ring 143, and the same pulley is further provided With a central, round projection 147 Which enters into the recess 145 of the other pulley and abuts against the Wall thereof, the two pulleys being held together by screws or bolts 1118. By this means, the pulleys are provided with a relatively broad bearing 'surface upon la relatively thin support, and the strain exerted by the pull ot' the chains 139 Will not cause any wabbling motion to said pulleys.

The pulleys 138 are provided, upon their outer faces, with oppositelydisposed crank arms 149, having their outer ends providedA with a' longitudinal series of apertures 150 for the adjustable connection of pull rods 151, which extend outwardly, transversely of the machine, and considerably beyond the sides ot the same, where they are connectedl as at. 152 (Figure 3) to shuttle transfer bars 153 which are 'adapted to be moved, longitudinally thereby 'through adjustable bearing blocks V154 carried by the ends of the angle irons 125 which extend considerably beyond the sides of the machine frames 1 and 2.

The transfer bars 153 are provided at their inner ends with shuttle holding members 155,\which are adapted to receive and release the shuttle 156 (as shown in Figure 12), upon being actuated by the lever 157, when the same contacts With the shoe 158 at the outer end of the lovvermost angle iron 125 and at the finish of the 'inward movement of the transfer bar 153 through the pull ot' the rod 151, but since this particular mechanism forms no part of the present invention, no detailed description of the same will he given. 1t will be seen, however, that by reason ot the particular arrangement of the' actuating mechanism for the transfer bars, the latter will be simultaneously drawn together, towards the center of the machine, where the transfer of the shuttle is made, and that the said bars are immediately caused to separate, moving in opposite directions, one of the holding members 155 carrying the shuttle on to the completion of the traverse, thus stretching the weft wire, transversely of the machine, alternately in opposite directions, to `form the filler of the fabric. ily reason of the regular advance of the fabric through the steady feed ot' the warp wires from the drum 13, at the rear end of the machine, and the steady take up of the woven fabric, through the steady feed of the warp wires from theV drum 13` l at the rear end ot' the machine, and the tion of the take-up drum 81, at the frontend of the machine, the said weft wires, placed by the shuttle, are caused to assume regular spaced relation to each other, While in per' fect parallel alinement. Said relation may be made to agree or not agree With the spaced relation of the warp Wires as may be desired, depending upon the timing of the various parts through the various means foradjustment, as Will be readily understood.

rllhis transit of the shuttle through the shed of the Warp Wires takes place when the quickly carried by one of the transfer bars to the center of the machine, when the trip lever 157 on each bar 153, by contacting with the lshoe 158, causes the opening of the holder 155, when the initial impetus of the shuttle 156 carries the same to. the opposite holder 155, which instantly starts to recede, through the action of the crank arms 149, thus receiving, grasping and lcarrying the shuttle on to the end of the stroke.

As the linis'h of said stroke is made, the cranks 126 and pitmenV 127 start forward carrying the hangers 120 and the lay ot the loom therewith, and forcing the said wett wire to its proper spaced, position at the fell of the fabric. said Wire being carried forward by the usual reed Wires 159 supported by reed holding strips 160 secured in the front open sides of thelangle irons 125, as indicated in Figure 3.

ln Figures 12, 13 and 14 there is illustrated the means for alining the shuttle transfer rods 153, so that the holders 155 may be accurately advanced towards each other for transferring the shuttle. The. bearing blocks 154C comprise a back plate 161,

which is held in position between the angle irons 125 and at the outer ends of the same, by means of bolts 162 passing through upper and lower flanges of said plate, and adjacent to each end, the latter is provided with vertically disposed slots 163. Tap screws 164 are passed through lthese slots from the rear, and have their forward threaded ends screwed into an adjustable guide plate 165, which is provided With a central, longitudinal projecting portion having an angular bearing seat 166 extending throughout its length and forming two sides of a square, one being the bottom and horizontal and the other a vertical side. A cap or cover plate 167 is applied to the projectingr portion of the guide plate, said cap having a longitudinally-disposed, angular recess or bearing seat 168 extending throughout its length and forming the othertwo sides of a square, that is the top and the other side thereof, said cap being held in its mounted position by means of bolts or screws 169. rlhe bearing formed by the

recesses

166 and 168 provides a relatively long bearing for the shuttle transfer rods 153, and it will be seen that by properly adjusting the screws 164 in lthe slots 163, the said bearing may be made to aline perfectly with the opposite bearing.

When it isdesired to 'turn the drum 13 by hand, in either direction, as is often the case when threading the warp wires A through the machine, or when a wire breaks and it is necessary to allow a little slack for splicing the same, the bevelled pinion 33 is moved forwardly on the shaft 27 to unmesh the same from the bevelled pinion 34, by depressing the foot pedal 57, thus breakin the train of gears fromI the drive belt 56. crank 170 located at the upper portion of the right hand front standard 6, (Figure l) is then grasped by the hand of the o erator and turned to rotate a short sha t 171, mounted in a bearing 172 on the side of the frame member 1. This short shaft, through a knuckle-joint 173, in turn, rotates an in`v clined shaft 174, having its lower end supported in an angularly disposed bearing 175, and carrying at its lower projecting en a bevelled pinion 176 which meshes with a bevelled gear wheelI 177 carried by the horizontal shaft 27. The bevelled gear wheel 177 which is mounted adjacent to the bearing 30 is provided in its hub portion with an annular groove 177, into which there projects the inturned terminal of a clip plate 17 7b which is bolted to said bearing 30, thus pr venting any longitudinal movement of th wheel relative to the shaft and at the same time permittingy the said shaft to rotate independently of the wheel 177. The shaft 27 is thus urotated in either direction asA desired, assumin that the pedal 57 is still de ressed and t at the clutch members 71 and 72 are disengaged.

When the pinion 33 is thus held forward, the socket 178 (see Figure 5) formed in the extension of the hub beyond lthe annular groove in which the shifting yoke 64 operates, is moved forwardlyl into surrounding relation to the toothed c utch member 179, formed on the rearwardly extendin hub of the bevelled gear wheel 177, the said socket 178 having complement-ary teeth for engagement therewith. It will thus be seen that cutting out the powerdriven train of gears throws the hand o erated driving means into connection witlli the driving shaft 27 for rotating the drum 13 in either direction to allow of correction or mending of the strand or warp wires or the woven fabric at the front end of the machine.

lt is also sometimes desirable to turn the take-up drum in one or the other direction, independently of the other parts of the loom and independently of the power ldriven gearing, and for this purpose the following means has been provided.

The take up drum shaft 79 is extended at the right hand side of the machine somewhat beyond the hub of the worm wheel 78, which latter is provided with clutch teeth 180, which are normally in mesh with complementary teeth 181 formed in the inner hub portion of a hand wheel 182 see Figures 7 and 9), and the said hand w eel is slidably mounted on the extended shaft 79 by means of a spline 183, havin an enlarged head for preventing the hand wheel from sliding oli' of the shaft when moved outwardly by the hand of the operator to break the connection between the

teeth

180 and 181. 'W hen such connection is broken, the hand wheel may be used to turn the drum shaft 79 and also the drum 81 in either direction without disturbing the rest of the gearing, as the worm wheel 78 is loosely mounted on the said shaft and may exert a rotary movement thereto, under power,v only when the hand wheel 182 is at its inner po sition to mesh the teeth.

At the rear end/of the machine, the standards 8 are continued upwardly and are provided on their rear faces with alined cradle bearings 184 which are adapted to receive end trunnions 185 of a rear idler roll 186, extending entirely across the machine and located over the drum 13. (Figure 2.) In front of the roll 186, the said upward extensions are provided with vertical slots 187 for properly adjusting substantially horizontal arms 188, having horizontall alined openings to receive the ends of guidBing and separating bars 189, which also extend across the machine and are supported in spaced relation by said arms 188, which terminate at heir forward ends in rectangular frames 19 At their front ends, the

side frame members

1 and 2 are also extended upwardly and formed into alined cradle bearings 191, for the rece tion of end trunnions 192 of a front idler rol 193, which also extends entirely across the machine, and whose front face is substantially over the front face of the aforesaid tension roll 82, there being an unobstructed passage between the two rolls. (Fi re 2.)

T e inner faces of the upward extensions 7u of the intermediate standards 7, at each side of the machine, are provided with ver tically disposed, spaced grooves 7b (Figure 4) for the reception of the usual heddle frames 194, but since the same may be of any desired construction, no attempt has been made to illustrate them in detail. These frames are adapted to be alternately moved up and down in their respective grooves by means of itinen 195, as best shown in Figure 2 of t e drawings, said pitmen derivin their power from oppositely disposed cran Iarms 196, arranged just within the

frame members

1 and 2, at each lside of the maeective lengths of said pitmen to be increased or decreased as maybe found necessar to give the proper amount of lift to the.

he dle frames.

The shaft 197 is provided at a point adjacent to the left hand frame member 2, with a forwardly extending operating crank arm 199, having a longitudinally adjustable wrist-pin block 200 (Figure 2), vand connected to this wrist pin is a drive pitman 201, the'upper end of which is connected to a substantially horizontal operating lever 202, located at the inner side of the frame member 2 and having its rear end pivot-ally mounted, for up and down rocking motion, upon a pivot pin 203 carried by the inclined portion 24 of the left hand frame member 2. Mounted on the transverse shaft 39 and at the inner side 'ofthe operating lever`202 is a wheel 204 having in its face adjacent to said lever, an eccentric groove 205 for the reception of a roller 206', mounted on a horizontal pin projecting from the inner face of the lever 202 and located directly below the lshaft 39. As the said shaft revolves through the medium of the gearing atl the other side of the machine, it will be seen that the eccentric groove in wheel 204 will cause an alternate up and down movement to the heddle frames.

Located at each side of the machine, just within the frame Amembers 1 and 2 and directly over the take-up drum 81, there is secured, as by bolts, a vertically disposed plate 207, having at its vertical front and rear edges ribs or flanges to form a vertical guide or runwa for a solid, round bar or roller 209, which has its ends projected into said guides or runways and is adapted toplie upon and to move upwardly as the diameter of the roll of fabric upon the take-up drum is increased, the said roller serving to wrap the roll uniformly. j

' When the drum, with the warp wires A previously wrapped in pro er manner and osition thereon, has been p acedin the bearmgs 10 at the rear of the machine and the cap members 12 secured in place over the trunnions thereof, the ends of said warp wires are first carried forwardly and upwardly and over the idler roll 186. Every alternate wire is then passed beneath the rst separating bar 189, and then over the secondbar 189, while the other alternate Leraars wires are passed over the first bar and under the second, the alternate wires crossing each other bet-Ween the two bars. From this point all of the wires are assed' forwardly in arallel relation to and through the eyes 4lnot shown) in the heddle frames 194, and then power is applied to the drive `\pulle 51 through the drive ybelt 56 and the train of gearing, as described, rotates the drum 13 in a relatively slow and regular manner to uniformly feed off the warp wires A therefrom.'

.At the samev time,A the heddles 194 are actuated by the cranks and pitmen to guide the wires and to alternately raise and lower the same for` the purpose of forming the shed B at the intermediate portion of the machine, in the region of the upstanding supports 116, the same shed B being located in the horizontal plane of the shuttle 156 when the hangers 120 are at their rearmost position adjacent to said hangers. Atthis instant, the cranks 136 act in'unison to cause a transverse movement of the shuttle across the lay of the lloom and through the shed B, whereupon the cranks 126 immediately drive the swinging frame forward to causethe reed 159 to carrv the weft wire last placed forwardly, and ilito spaced relation to the previously placed weft wire, such timingv of .the parts and s acing of the wires being readil accomp ished by the `various means of a justment provided, and by means of the interchangeable speed gear 36 which provides for al faster or a slower motion of the drum 13 and the other actuated parts.

At, this time the clutch members 71 and 72 are separated by reason of the fact that the lever 102 isheld in elevated position by the pin 105 which now' rests upon the lug 104, the coiled spring 106 exerting a constant p ull to hold the two members in such relation.

Since in the present maehine, the finished product must be vdrawn ,under tension away from the point of weaving and wrapped or wound upon a drum or roll acting as the pulling .or feeding medium and since, in the weaving of cloth or fabrics,` the same must be
