Like numerals refer to like parts throughout the several views of the drawings.

ln general, the operation of the loom which is hereinafter specifically described and its general operation hereinafter more particularly described, is as follows: The strands of wire rope which form the warp pass from reels, upon which they are wound, through a take-up device, thence to heddles forming the shed and from the shed the fabric, after it is woven and the filling beaten up therein, passes through two horizontal rolls which press against the surfaces of the belt in order to straighten said belt and make it smooth and also between two edge rolls which bear against the'edges of the belt in order to still further straighten said belt. Fronnthese compressing rolls, the belt passes between feed-rolls to a convenient reel upon which it is wound. The filling is also wound upon a reel and consists of two filling strands, one wound upon each reel, the reels being located upon opposite sides of the warp at the same time. These reels are propelled. in opposite directions simultaneously by suitable mechanism :from

one side of the shed to the other and are carried upon slides which slide in ways extending outwardly from the shed upon opposite sides thereof, said slides being so arranged and of such dimensions that they reach the ways upon one side of the shed before leaving the ways upon the other and also engage the driving mechanism upon one side of the shed before leaving the driving mechanism upon the other side thereof. lVhen the shed is open these reels are propelled, as

hereinbefore'stated, in opposite directions simultaneously through said shed. After they have passed; through the shed, the lay operates to beat up the filling thread, the heddles operate to change the shed, the feed rolls operate to feed the fabric. and the take-up mechanism operates simultaneously with the heddles to preserve the proper tension upon the warp-threads forming the shed.

The reels and the other mechanism hereinbefore referred to are automatically driven at the proper time to secure the results hereinbefore set forth and this is accomplished by means of two clutch mechanisms, one clutch mechanism being a reversing clutch mechanism and connected by a suitable mechanism to thereels to impart an intermittent reciprocatory motion thereto, while the other clutch mechanism is an auxiliary mechanism which operates different instrumentalities to operate the heddles, the beatup, the feed, and the take-up.

The slides upon which the reels are journaled are driven in opposite directions and one of said slides at one end of its movement strikes a tripper lever which, through suitable mechanism, operates to throw the clutch mechanism into its central position and the reel slide then stops. During this throwing out operation, the auxiliary clutch is thrown into operation, and while the slides with the reels thereon are stationary, the heddles, beat-up, feed and take-up are operated in their proper order. When they have been operated, as desired, to beat up the filling thread, change the shed, feed the fabric, and operate the take-up in proper time, the auxiliary clutch is thrown out and the reversing clutch mechanism thrown in, whereupon the slides carrying the reels move in opposite directions and carry the strands across for a new pick.

The specific mechanism by which the operations hereinbefore referred to in general are accomplished will now be described.

The main driving shaft 30 (Figs. 2, 10 and 11) is journaled in suitable bearings in the frame 31 and has fastened thereto pinion gears 32 and The pinion 32 meshes into the gear 34 and the pinion 33 meshes into an intermediate gear 35 which, in turn, meshes into a gear 36. The gears 34 and 36 are both journaled to rotate upon the clutch shaft 37 (Fig. The shaft 37 has fastened to the right hand end thereof (Figs. 1, 2 arid 3) a bevel ear 38 which meshes into a bevel gear 39 ast to the vertical shaft 40 and also meshes into a bevel gear 41 fast to a vertical sleeve 42. The f 115 vertical shaft 40 rotates within the sleeve 42 in an opposite direction therefrom and both sleeve and shaft are supported ppon suitable hearings in the frame of the machine. The slecve 42 at its upper end is fastened to a spur gear 43 and the shaft -40 has fastened to its nppen end a spur gear 44. These gears 43 and 44 operate to drive the lower and upper carrier slides for the lower and upper reels at the right hand end of the loom, respectively.

The left hand end of the clutch shaft 37 has fastened thereto a bevel gear 45 which meshes into a bevel gear 46 fast to the vertical shaft 47. Said shaft 37 also has fastened thereto a bevel gear 48 which meshes he apposite diroetion the/re f? and sloeve, 5o rotate in .=,d a aptly year 52, (5B6 Figs. 1, ar 5'2 meshes into a noel shaped carrier le l:- adapted to km. 5(3 ftmned in respertively. fastened nnnrhine upon opposite carrier slido Si is i 3%, which is free ids .31..

The upper carrier slide 63 is arranged to slide in brackets 68, 69 fast to the frame upon opposite sides of the shed. It will be seen that by stopping the shaft 37 internnttently and then reversing the same. the carrier slides with their reels will be moved first in one direction and then in the, opposite e'lirection through the shed to carry the different picks in a manner hereinafter more fully described. i

Friction brakes 70. 70 (Fi t 8) are applied to the reels to prevent their rotating: too freely by means of screws 71 having screw-- threaded engagement with the opposite ends, respectively. of the reel slide 59.

The filling 72 is led from the reel 61 (Figs. 6 and 7) between guide rolls 73. 73 rotatahly mounted upon pins 74. H 'last to a guide frame 753 whieh has two arnm said arms being: fastened at their free ends to opposite ends. respectively. of the slide :39. so that said filling passes from the reel (31 between the rolls 73. 73 and/ is thus guided between the warp threads as the reel passes through the shed. The upper reel M is provided with a similar deviee for guiding: the filling strands.

The reciproeatory movement of the hed-- dles. the movement of the lay and its reed. the movement of the take-up. and the feedot' the belt as it is woven are all aenomplished by certain mechanisms and instrumontalities hieh are actuated by an auxiiiary clutch sleeve 76 (Fig. 3 whieh has teeth 77 adapted to engage teeth 79 upon the right hand face of the gear 31. This clutch sleeve To is loose on the shaft and has lateral grooves 79 into whirh corresponding lugs 80 projeet. These lugs are integral with a sleeve 81 rotatal'ily mounted upon the shaft 37. and to this sleeve are fastened the several gears and rams whieh aetnate the difl'erenl meehanisms for operating the heddles. the heating upanwhanisnl the feed. and the take-up whieh mechanisms we will now proceed to s n-eifieally deseribe.

The warp strands R2. 82 (Fig. *2) pass from reels (not shown in the drawings) bw neath and partly around a roll 83 journaled t rotate upon a shaft Sitast to hraekel's 8' upon the frame. of the machine. Said warp strands are held upwardly against sa id roll 8;) by a. guide roll 86 journaled to rotate upon a shaft 87. the opposite ends of whieh are supported in arms pivoted at 89 to the bracket 85. Said roll so is held upwardly against the under side of the warp strands by suitable adjusting serews :H), The warp strands pass upwardly around the roll 83 and over a whip roll 91 journaled t rotate upon a shaft 92 which is fastened at its opposite ends to arms 93 fast upon the shaft 34. An arm 94 is fast to the shaft 84 and has a link 95 adiustably fastened thereto. the opposite end of said linl; lining nonnected to a rocker arm shaft 97 journaled to rock in a suitable bearing in the frame of the machine and having fastened to its inner end a cam lever 98 which is provided with a cam-roll 99 adapted to bear against the periphery of a cam 100 which is fastened to the sleeve 81.

The operation of this particular mechanism is as follows: When the sleeve 81 is rotated the cam 100 being fastened thereto will rotate with it, rocking the cam lever 98, the arm 96 and, through the link 95, rocking the arm 94 and the arms 93, 93 with the whip-roll 91 thereon. Thisrocking movement of the whip roll 91 takes place at the time when the heddles are changing the shed and keeps the correct amount of tension upon the Warp strands.

The reciprocatory motion of the heddles by means of their harness to change the shed will now be described.

Referring to Figs. 1, 2, 3, 13, 21 and 22, the heddle 101 consists of a guide-bar having a slot 102 extending longitudinally thereof and laterally therethrough, and in this slot are located two guide- rolls 103, 103

which are rotatably supported upon pins 104, 104 fast to said guide-bar. The harness by means of which the heddle is reciprocated consists of flexible connections, preferably in the present machine of wire cords or ropes, 105, 106. The connection 105 is fast to the lower endof the heddle and extends downwardly therefrom around a guide pulley 107 which is journaled upon a shaft 108 fast to the frame of the machine. The lower end of said connection 105 is fastened to an eye-bolt 109 which passes through the front bar 110 of the rec'iprocatory frame 111 and has screw-threaded engagement with a nut 121. Said reciprocatory frame 111 is adapted to slide in ways 112 on the side frames of the machine (Fig. 2). The connection 106 extends from the upper end of the heddle 101 over a pulley 113, thence partly around a pulley 114, over a guide pulley 115 downwardly to a guide pulley 116, thence horizontally along the reciprocatory frame 111, to the rear end of which it is fastened in the same manner as hereinbefore described in relation to the connection 105.

The guide pulleys 113, 114 and 115 are rotatably supported upon shafts 117, 118 and 119. respectively, fast to the frame of the machine. and the guide pulley 116 is journaled upon a shaft 120 fast to the frame of the machine. It will be seen that by rotating the nut 121 by means of a suitable wrench 122 (Fig. 9) the tension on the connections may be adjusted so that said flexible connections 105 and 106 may always be properly adjusted to remain taut.

The reciprocatory frame 111 has racks 123. 123 on opposite sides thereof which mesh into gears I124, 124 fast to a shaft 125 96 fast toa rocker journaled ,to rotate upon the frame of the machine and having fastened thereto a pinion 126 which meshes into a rack-bar 127 adapted to slide in a rocker frame 128 pivoted upon the shaft 125. The rack-bar 127 is pivoted to a crank-pin 129 fast to a gear 130 fast to a stud 131 journaled to rotate in the frame of the machine. The gear 130 meshes into a gear 132 fast to the sleeve 81. It will thus be seen that when the sleeve 81 is rotated the gear 132 will be rotated, thus rotating the gear 130 and imparting a reciprocatory motion to the rack bar 127 which, as it slides in the rocker frame 128, imparts a reciprocatory motion to the pinion 126 and gear 124, whereby a reciprocatory motion is imparted to the racks 123 and the frame 111, thus alternately moving the heddles up and down through their connections 105 and 106. The crank-pin 129 is adjustable radially upon the gear 130, so that the throw of the rack-bar 127 and, therefore, of the racks 123 may be increased or diminished, as desired, to increase or diminish the throw of the heddles and the opening of the shed.

The fabric is fed, Figs. 1, 2 and 4, by means of the feed rolls 133 and 134. The feed roll 133 is fast to a shaft 135 journaled to rotate in bearings 136 formed in brackets 137 fast to the frame. A gear 138 is fastened to the shaft 135 and meshes into a gear 139 fast to the lower feed roll shaft 140. The lower feed roll shaft 140 is journaled in boxes 141 adapted to slide'in slots formed in brackets 142 and adjusted in said slots by means of screws 143 to bring more or less pressure to bear upon the fabric between the rolls 133 and 134. An intermittent rotary motion is imparted to the roll 133 by a pawl 144 pivoted to a pawl-lever 145 which is mounted to rock upon the shaft 13.5 and to which a rocking motion is imparted by a link 146 which is connected at its lower end to a cam lever 147 pivoted to a stationary shaft'148 and having a cam roll 149 journaled thereon and arranged to bear against a cam 150 fast to the sleeve 81. It will be seen that as the sleeve 81 is rotated the cam 150 will impart a rocking movement to the lever 147 and, through the link 146, a rocking movement will be imparted to the pawlcarrying arm 145 which will move the pawl 144 to impart an intermittent rotary movement to the ratchet 151 with which said pawl is adapted to engage. A stop-pawl 144 prevents the ratchet 151 from rotating backward. v

The amount of feed imparted by the rolls 133 and 134 to the fabric may be increased or diminished by means of a shield 152 which extends over the teeth of the ratchet and is fastened to a bracket 153. said bracket being adjustably fastened by means of a bolt 154 to the bracket 137 at the right of rolls are illustrated in Figs. 1, 2, and 14.

The rolls 156 and 157 bear against the upper and lower surfaces, respectively, of the fab ric, the lower roll 157 being journaled to ro tate in brackets 158, 158, and the upper roll 156 is journaled to rotate in boxes which are adjusted in said brackets to bring more or less pressure'to bear upon the fabric by means of adjustin screws 160, 160. V

The-edges of t e fabric are formed by means of the presser rolls 161, 162 (Fig. 1 1) which are journaled to rotate upon studs 163, 164, respectively, said studs being formed upon boxes 165, 166 which are adapted to slide in ways 167 upon the frame of the machine and are locked in position, when adjusted to the desired location, by means of locking nuts 168, 168. The boxes 165 and 166 with their respective rolls are adjusted toward and away from each other by means of a right and left adjusting screw 169 which is journaled to rotate in the frame of the machine and is rotated by means of a hand-wheel 170. It will thus be seen that by means of the surface rolls 156" and 157 and the edge rolls 161 and 162, the surface and edges of the belt may be rolled after having been. woven, so that the resultant fabric is smooth and even. These rolls become necessary in fabric of the character hereinbefore set forth-that is, in belts formed of covered wire strands, said strands'being somewhat inflexible as compared with cords or thread and, therefore, not being easily formed into a fabric having' a smooth surface without the aid of the forming rolls hereinbefore described.

The lay and reed and mechanism by which they are operated by means of which the filling strands are beaten up are illustrated in Figs. 1, 2, 3, 5, 15, 16 and 17. Referring to these figures and more particu- -larly to Figs. 5, 15, 16 and 17, it will he seen that the reed 171 consists of a plurality of fingers 172 adj ustahly fastened to a shaft 173 by means of clamp nuts 174. The shaft 173 is rigidly fastened to links 175, 175 which are pivoted at their lower ends to auxiliary rocker arms 176 and 177 which are rigidly fastened to the cross-shaft 178,.said

-('.l'osS-!-;huft being journaled at its opposite ends in the primary rocker arms 175) which constitute the lay. 'lhe prmnu'y rocker arms 179 constituting the lay arc jourualcd to'rock upon studs 180, 18-) \\'lH('ll are lastcned to hrmtkcts 161 \VllHfll, in turn, are

fast to the frame of the machine. A 182 is fastcnc l t primary rocket to the frame (it is;

spring site ends of the shaft 173 are adapted to slide in slots 183 provided in the rocker arms 179. Each of the rocker arms 176 and and has a cam roll 188 journaled thereon and adapted to bear against a cam 189 fast to the sleeve 81.

The operation of the lay and reed in beating up the filling is as follows: The cam 189 rocks the cam lever 187 and through the 1 link 186 conununicates a rockin movement to the arm 185, the rock-shaft 1' 8 and auxiliary rocker arms 176. and 177. These rocker arms, in turn, move the links 17 5 upwardly, together with the shaft 173 which is'fastened thereto and which slides longi tudinally of the slots 183 in the primary, rocker arms 179. The fingers 172 are thus moved longitudinally of the rocker arm 179 from the position illustrated in Fig.15 to that illustrated in- Fig. 16. 'Thus the fingers are inserted between the warp strands. A continuation of the rocking motion hereinbefore referred to of the auxiliary rocker arms 176 and 177 causes the stop screws 184 to abut against the studs 180 and at this time a continued rocking movement of the" rocker arms will cause the auxiliary rocker arms 176 and 177 to rock-and also the pri-':

mary rocker arms 179 as one piece. The

auxiliary rocker arms 176 and 177 and the primary rocker arms 179 thus constitute,-as a whole, a lay pivoted upon the studs 180, and this rocking movement will move the, fingers constituting the reed from the position illustrated in Fig. 16 to that illustrated in Fig. 17, thus heatin up the filling 72.. The link 186 is adjusta )ly attached to the arm 185 by means of the stud 190 which projects into a slot 191 in said arm andis, clamped to said arm by a nut 192-.

Vi e will now proceed to describe there-- versihle and auxiliary clutch ineclgianisms and the instrumentalities-by which they are operated. 1

Said rocker arm. 200 is fast to a rock-shaft 201 adapted to rock in a suitable bearing formed in the frame of the -machine, said rocker arm having fastened to its rear end (Fig. 23) another rocker arm 202 which is connected by a link 203 to a rocker arm 204 first to a rock-shaft 205 and having fastened to its forward end a rocker arm 206 which is adapted to be enaged by an arni 207 fast to the slide 54.

he link 1.99 has a cross-pin 208 fast thereto ('Fig. 11) which projects into slots 209 formed in the'clutch-lever 194 and concentric with the pivot 19? of the rocker-plate 198. The link 210 is pivotally connected to 202 by. a cross-pin 212 which is fast to the rocker arm 202. Said link 210 is connected at the. right hand end thereof (Fig. 18) with a rocker arm 213 pivoted at 214 to the frame of the machine. Said rocker arm 213 is further connected by a link 215 to a rocker arm 216 connected by a link 217 to a rocker-arm 218. fast to a shaft 219 adapted to rock in bearings formed in the frame of the machine, and having fastened thereto a rocker-arm 220 which is adapted to be engaged by the arm 221 fast to the carrier slide 54, when'said carrier slide is at the extreme right of its movement, as viewed from the front of the machine. 'A rod 222 is adapted to slide'in the bracket 223 (Fig. 3) fast to the frame of the machine and is connected at the right hand end thereof by a pin 224 to the auxiliary clutch lever 225 which is pivoted at 226 to a bracket'227 fast to the frame of the machine. Collars 228 and 229 are fastened to the rod 222. Collars 230 and 231 are slidable upon said rod and springs 232, 232 encircle the rod 222 and are interposed between the collars 228 and 230 and the collars 229 and 231. The distance to which the collars 230 and 231 can slide upon the rod 220 toward each other is limited by suitable cross pins 230 and 231 extending through said rod.

The auxiliary clutch slide 76 is normally held with' its teeth in engagement with the teeth upon the side ofthe gear 34 by spiral springs 233, 233, but is forced away from or toward the right (Fig. 19) by an inclined projection 234 thereon which is adapted to enga e a corresponding incline upon a lever 235 5 Figs. 10 and 19) pivoted at 236 to the bracket 227 and luiving a friction roll 237 thereon which is adapted to bear against the upper cam-shaped surface 238 of the A spring 239 holds the friction roll 237 in contact with the cam surface 238 of the rocker arm 213. The upper end of the lever 225 is provided with a roll 240 which projects into a cam groove 241 in the ram 242. The cam 242 is fastened to the sleeve 31 and has a latch 243 located in said cam groove and pivoted to said cam In the form of our invention hereinbefore pulleys 113, 114, .115, 107 and 116 are all in the same vertical plane, but in order to simplify the-construction, as illustrated in Figs. 24 and 25, two heddles 101, 101 may have a single set of connections 105', 106 and 106?. The reciprocatory frame and the manner in which it is driven is the same in this case as in that illustrated in Fig. 13, but the guide pulleys 113, 114 and 115, instead of being in the same plane, are placed in different planes, the pulley 113 being in the same plane as the guide pulley 107 and the guide pulley 115 being in the same plane as the guide pulley 116, while the guide pulley 114 is placed midway between the guide pulleys 113 and 115. Thus, while the two heddles are in different planes, as required to guide two warps, one set of connections can be utilized, thus simplifying the construction and rendering it easier and cheaper to manufacture.

Thegeneral operation of our improved loom is as follows: The warp strands are led into the machine from reels (not shown in the drawings) as will be seen by reference to Fig. 2, between the guide rolls 83 and 86, thence upwardly around the whip roll 91, thence through the hcddlcs 101, 101 and from the lie ddles, to the woven fabric or belt. Said woven fabric or belt passes between the forming rolls 156 and 157 and between the edge forming rolls 161 and 162. Said belt then passes between the feed rolls 133 and 134 and from the feed rolls passes to a reel upon which it is wound. said reel not being shown in the drawings. Assuming the parts to be in the positions shown in Figs. 1, 2 and 18, with the lower reel and its slides at the left of the warp and with the upper reel and its slides at the right of the warp. the teeth of the reversible clutch sleeve 193 are in engagement with the teeth upon the gear 34. Said gear rotates in,the direction of the arrow thereon (Fig. 18) and the shaft 37 rotating in the same digection rotates the shafts 40 and 47 and hollow shafts or sleeves 42 and 50 in opposite directions, respectively,

thus rotating the gears 43 and 44 and the gears 51 and 52 in the proper directions to more the upper reel 64, with its slides, toward the left, and the lower reel 61, with its slides, toward the right (Fig. 1). \Vhen the carrier slides 54 and (53 first start to move across the shed, the auxiliary reel slides .39 and 66 will move with their respective car rier slides until the tension upon the respective filling strands upon said reels tightens sufficiently to hold said reels while the rar-
