I The frame comprises a base 1, from which pillars 2, the present instance eight. in number, uprise and support a table 3. From the table 3 smaller pillars 4 uprise and support a cap plate 5. v The number of pillars 4;

is, in the present instance, sixteen, located at equal distances apart. The pillars 2 also support an intermediate annular table 6 on which heddle operating slides are located as will hereinafter appear.

The table 3has seated thereon a-central ,1

table 7 providedwith a hub '8 connected with the rim by arms 9. The table 7 has amarginal flange 10 which overlaps the inner" edge of the table 3 while the periphery-of said central tahlejbelo'w the marginal flange fits withinthe table. 3 holding the table 7 centered and permitting its removal up- .manipulating-mechan-ism, 11 is a top .plan view of the'same, Fig. 12 1S a'sectlonnf ward without disturbing thefpillars2 and and tabla-3i.

iio

Centrally in the base 1 there is an opening 11 around the margin of which an inverted' cup-plate 12 is secured, a tubular part 13 extending upwardly from the top of the cup plate. Around the crown of the cup plate there is a flange 14 to arrest dripping oil or grease and at the top of the tubular part 13 there is a bearing flange 15.

A tubular foot piece 16 fits within the tubular part 13 and a supporting flange 17 on saidtubular foot piece rests on the bearing flange 15. v A cam wheel 18, for operating the heddles, has its hollow hub 19 bolted to the top of'the foot piece 16, and to the top of the hub 19 the hub 20 of the master end of a supporting rod 24, the latter being 1 provided with a screw threaded portion to screw into the base of the pin, and with a collar 26 in position to engage the bottom of the pin when the rod is screwed in to its limit. The rod is centered by passing through the hub 27 of a spider 28 seated on an interior shoulder 29 in the hub of the master wheel 21 and extends thence'downwardly to a point within the cup 12 where it is provided with a rack 30, removably secured to the rod by means of a split sleeve 31 and screw 32. A horizontal shaft 33, mounted in suitable bearings on the base 1 and in the cup plate 12, has, on its inner end, a pinion 34, held in engagement with the rack 30 by a shoe 35, provided with

perforated cars

36, 37 through which the shaft 33 extends. The rack 30 is free to slideup and down in the shoe 35. The outer end 7 of the shaft 33 is provided with a worm wheel 38, engaged with a worm 39 (see Fig.

- "the machine or when the latter is at rest:

14) on an upright shaft 40, the latter 113V. ing a hand wheel 41 secured to its upper end for manipulating it andhence through the worm '39, worm wheel 38, pinion 34 and rack 30, adjusting the weaving pin 23 up and down at pleasure durmg'the operation of The shaft 40 also serves as a way for the heddle frame to slide on and occupies a position corresponding to one of the fixed ways to be hereinafter described annular groove (not shown) on the shaft 33. To permit the shaft 33 who withdrawn The shaft 33 is held against longitudinal' dis lacement by a screw pin 42 passing throng the bearing on'the base andmto anfrom within the cup plate 12 to free the interior of the bore, formed by the superposed

parts

16, 19 and 22, from obstructionwhen the loom is used for covering hose, the lower end of the shaft 40 is held in position by a a swinging hook 44 removably clamped to the said bearing by a set screw 45. By releasing the hook 44 the lower end of the shaft 40 may be moved away from the worm wheel-38 sufiicient to disengage the worm from the wheel and then by unscrewing the pin 42 the shaft 33 with worm wheel thereon may be drawn'outwardly from within the cup plate 12and at the same time from the

ears

36, 37,- on the shoe 35, releasing the On the upper end of the hub 8 of the center plate :1, an interiorly screw threaded collar 46 is secured and a hollow nut 47 is performing the'double function of a weft lay or weft guide support and a centering guide for the w ing pin is seated on an annular interior shoulder 49 within the nut 47 The upper edge of the ring 48 is transversely corrugated as shown at 50 for preventing lateral displacement of the warp threads-during the operation of weaving as will hereinafter appear. By screwing the nut 47 up or down the weft lay supportcarwith relation to the weft lay carried by the shuttle.

Shuttle-Two shuttles are employed aranother in structure and operation. A description of'one will suffice. The shuttle frame is denoted by 51. It is ofskeleton formation and has two supporting wheels anannular track 54,.faced with-raw hide 'or' other suitable noise reducin material. The frame 51 also .has journa ed therein three pairs of

guide wheels

55, 56, 57, on upright journals, the upper wheel of each pair engaging the inner wall of an upper engagin the inner wall of a lower comb 59. The sai' shuttle frame has-also journaled therein on upright 'ournals two airs of pair engagin the outer wall of the said upper comb an the lower heel of each pair engagin the outer "wall .of the said lower comb. he said guide wheelsare preferably made of. raw hide or other suitable noise reducing-material. The upper comb 58 is curved to conform to the track'54 and'is fixed to a plate 62 sup-- ported'byand removable from an annular late 63. carr1ed by the pillars'4, and the ower comb 59eissimilarly curved and fixed to the center plate 7 These coinbe or hook 43 formed on the shaft bearing and by shoe and permitting it and the shaft 24,: ,spider 28 and weaving pin 23 to be removed.

fitted to screw into the collar 46. A ring 48 rie'd by the nut may be accurately adjusted.

ranged to'travel'tandem and quite like one 52, 53, which track one after the other along w comb 58, and the lower .wheel of each pair guide

wheels

60, 61, t eupper whee of each picket fences are located one above the other'with their teeth directed toward one of weaving, while the ends of the teeth are so located and formed that the'warp threads will be properl engaged and separately Q guided to the en s of the slits.

The back or outer edge of the shuttle isprovided with a curved rack 65 for engaging the shuttle driving pinions' to be hereinafter described. A broad upright bearin rim 66 on the shuttle frame above the rac 65 engages rollers on thedriving piniong shafts to hold the rack and pinions in proper 3 mesh to prevent both cramping and lost mdtion. he rollers above referred to will be -more particularly described in connection with'the-drive mechanism.

The weft la or guide-carried by the shuttle-consists 0 an arc-shaped piece 67 (see Figs. 24 to 28) provided on its face with a spiral groove 68 along which the. weft thread is guided, the pitch of the spiral groove being preferably equal to the diameter of a thread from the point where the thread entersthe groove to the point where it leaves thegroove, so that the Weft threads, during the passage of the shuttle along a given 'point' on the weaving pin will screw the thread snugly against the previously 'laid thread. The entering end of the weft lay or guide is turned slightly to one side of center as shown at 69, to insure theentrance of the lay or guide between the two sets of j warp'andthe trailing end of said lay or into position.

guide is cut away as shown at 70 to free the 4 1 Weft thread being laid from any obstruction between it and the previously laid weft thread as: the lay finally forces itsthread Thelay or guide 67 has a curve properly related to the-curve of the weaving pin,'and as the latter is changed in diameter, the lay or guide is replaced by another to suit the conditions.

-,Figs." 27 to 29 show a lay or guide 71, suited to a Weaving pm of smaller diameter than the pin to which the lay or guide 67 is suited but in other respects the lay or guide 4 71 is quite similar to the lay OIfl-g'lfidt: 67.. P

The lay or guide is removably secured to g a curved holder 72, the .face ofthe holder being provided with a groove 73 forre'ceiving a pin 74 on the back of the lay orgaide and screws,,.75 extending through the ht'ider and intoscrew threaded sockets tapped into" the backv of the lay. The holder 72 is further provided with laterally extending flanges 76, 77, which gradually increase in guide enters .andserves-to spread the said sets 'to'receive the lay, and the trailing endof the holder is constructed to pass from between the sets of warp before the trailing end of the lay passes to allow the sets of warp to begin their change ofpos'itions under the action of the heddles at the earliest feasible moment ready for the following shuttle. Where the lay is made for weaving tubular'fabric of smaller diameter, the advance end of the holder may be given an outward curve, as'shown at 7 8 (Fig. 27 to r cause its flanges to spread the sets of warp more abruptly with respect to the advance end of the lay. The holder 7 2 is removaibly secured to the shuttle frame by means of

arms

79, 80,- bolted-to projections-81, 82, on the frame and to admit of accurate adjustment-the holes 83 through which the bolts 84 pass re elongated. The holder-is further providdd with a guide pulley 85, aroundwhich the weft thread from the cop passes to a hole 86 communicating with the groove in the lay, near its advance end. The said lay or. guide coacts with, the sup port 48, hereinbefore described, the said support serving to prevent the lay from being crowded away from the edge of the fabric being Woven and hence causing the.-

weft thread being laid to be gradually forced by the spiral incline, tightly against the previously laid weft thread.

The cop holder is denoted by 87 and consists'of hollow cylinder for receiving the cop, one end 88 (see Fig. 21) being hinged at 89 to swing open, the said end being provided with a thread hole 90. A; rod or tube .91, provided with a thread passage 92, leading from the end of the rod or tube through the side of the tube, is spaced from, and attached to the body 87 of the'cop holder by means of bands or clips 93, 94, around the ends of the said body. The rod or tube 91 is employedjto apply tension to the weft and is'pro-vided with a scale 95 todetermine its rotary adjustment. A nut 96 on the end; of the rod ortube 91 serves to hold it in the desired adjustment.

The side of the holdcrx87, preferably oposite the tension rod or tube 91, is, provided with a dovetail tongue97, the jlower edge of. which seats in a fixed jaw 98 on the shuttle frame, and'the upper edge of which is embraced bythe. jaws .99 of two clamping plates 100, 101, the opposite edges of 10a 'lrjifigeishuttle frame. Bolts L04, 105,

extendingupwardly through the frame and the shuttle for manipulating the cop holderand, at the same time, maintaining a continuous spreading of the warp threads, the adjacent ends of the auxiliary and cop holder supported spreaders bein so overlapped as .to form no break in the ing action. It is to be understood that spreaders corresponding to those notedon the upper side of the shuttle are provided on the under side of the shuttle. o

1Ied lles.-The heddles are arranged in banks, in the present instance sixteen banks,

each bank comprising an outer and inner element, the. outer element handling one set of .warp threads and the inner element its companion set of warp threads which make up a shed, sixteen sheds being employed to distribute the warp around the complete periphery of the weaving pin. It is to be understood, however, that the number of number;

sheds ofwarp is-a matter of choice-and I do not wish to limit m self to a particular The heddle ame of an element comprises side rods' 110, 111, and end slats 112, 113,the ends of which are let into,

slots

114, 115, in the ends of the side rods, it being understood that the lower end of the side rod 110, is provided with a slot correspond: ing to the slot 114 and the lower'end of the side rod 111 with a slot. corresponding to the slot 115, to receive the ends of the bot= tom end slat, 113. One of the heddles is shown in detail in Figs. 15, 16, 17, and consists of a'flat strip of metal-116. provided with

slots

117, 118, near itsopposite' ends and at its middle portion with a clip 119.

struck up from the body of the strip and serving with the portions of the strip on the opposite sides of theclipto retain a thread eye ,-120, through which the wa thread passes. The heddle bars 121, through the

slots

(Fig. 12) to admit away from the bar 122, to hold the-heddles extended. For this 110'and'111 are provi ed with

screw threads

124, 125, and

nuts

126 and 127 are located on said threaded-portions below] the bar 121 and in engagement with the bar. 'Thenuts spread- 22, pass urpose the side rods f 126 and 127 are provided with suitable lock' nuts to hold them in position. At the corners of the heddle frame, half bearings 128, 1'29,-

130, and 131, are riveted at two corners on one side and bolted at the other two corners in order that the frame may be readily taken from the ways. The ways with which the half bearings engage and on which the heddle frame slides up and down, are denoted by 132, 133, and are held in

brackets

134, 135, supported on the pillars 4. In like manner each element of each of the banks of heddles is constructed and arranged;

For each bank of heddles there is a heddle operating slide 136 provided with a pin 137 carrying an anti-friction roller 138 which enters the cam roove in the cam 18. I The slide 136 is suita ly housed in longitudinally sliding adjustment and has a rack 139 at its outer end, with which a pinion 140 is held in engagement by a cup bracket 141, in which the pinion is mounted, the said bracket being bolted to the housing of the slide 136 on the table '6. The shaft of the pinion 140 has fixed thereon oppositely extending

arms

142, 1 43, one, connected by a a link 144 with one heddle frame of a bank and the other connected by a link 145 with the other heddle frame of a bank. The cam 18 is so shaped that it will promptly operate the slide 136 at each of two equidistant points throughout its length during a single rotation of the cam and these points are so related to the positions of the two shuttles that the slide and hence the two sets of heddles of a bank will be operated between the passing of one shuttle and the approach of the other shuttle. In like manner each bank of heddles will be successively operated during the rotary movementof the cam 18.

1 Warp tension and evening roZZa-Around the base 1 there is a roller suptporting frame 146 in the form of a mutilate ring, a short portion which extends along the neck of the. base. 1 where the loom driving mechanism is located being thrown out of the fair line of the ring. The frame 146 is removably secured to the base 1 by any suitable means, in

the present instance by means of several 1 pins 147 (see Fig. 5) which enter sockets 148 in the ringframe 146 and sockets 149 in the base, the said pins being held in place by

set screws

150 and 151,'am"; further by

bolts

152, 153, passing through lugs on the ring-frame into :the neck-of the bso. The frame 146 is provided at suitable intervals throughout its length with outwardly diirected supporting armsarranged in pairs,

the members of a pair being denoted by 154, 155, and between two arms, one of each pair, a warp evening roll 156, is located, journaled in the arms. In the present instance, there ,are sixteen of these warn evening. rolls, the.

term"evening'gbeing applied to indicate their function in evenly distributing the sheds.

tension throughout the entire circuit of warp The rolls 156 are interconnected by intermeshing gears, two such gears being indicated by 157, 158, so that they move together as though they were one. these warp evening rolls, in the present instance two, adjacent. to one another,.are so constructed that they can be released from" their companion rolls, at the pleasure of the operator, to permit them to rotate without disturbing the gears which connect them to their companion rolls. The two special rolls referred to are denoted by 156*, being duplicates of each other and each having a pair of

hubs

159, 160, independent. of the regularroll hubs 161, the latter loosely mounted on the roll shaft 162 and'fixed to the body of the roll, While the

hubs

159, 160, are screw-threaded on the shaft 162 and also arranged that they 'inay be screwed toward the opposite ends of the roll to lock it to the shaft 162, or screwed to their shafts the operation of weaving.

' shaft.

release it and permit it to rotate on the These special rolls are located in proximity to the tension roll to be hereinafter described, and serve to enable the op erator to gain access to the tension roll by releasing the rolls .156 and then drawing ofi' suflicient lengths of warp to permit the warp from the rolls 156* to be pushed aside. After the occasion for so pushingaside the warp has passed the said rolls 156* maybe turned by hand to take the drawn off warp back again and then by locking the rolls 156" may proceed, the relative positions of the evening rolls remaining unchanged.

The tension roll, denoted as. a whole by 163, is shown in its relation to the evening rolls in Fig. 1 and in detail in Figs. 8 and 9. It is mounted in a two-armed bracket 1641- fastened to the ring frame 1. 16, and cardistances apart. series of ring-like, fiat-faced disks 171, having their opposite faces within the fair path 1 a contact. Whatever tension 1s so applied Wlll of the rods170 provided with suitable friction material 172. The

flanged hub

168,3 carries the gear 165 and the two hubs 168, j 169, are mounted respectively on drums 17 3,-

174, made fast in the arms of the two arined bracket 164. The drum s,173, 174, are provided with outward extending flanges'l75,

176, at their outer ends, through which they I are secured to the arms of the bracket and with inwardly extending flanges" 177, 178, attheir inner ends, through which flanges pass a series of rods 179, in the present. ina Certain of The said tension roll consists of acylindrical shell 167, secured between two j flanged end hubs 168, 169, the flanges on 'ries of disks 182 are mounted, the disks 182 extending outwardly between the friction material on the faces of two adjacent disks 171 and. the end caps 180, 181, engaging the friction material on the-outer faces of the disks 171 at the opposite ends of the series. The rods 179 are within-the ring disks 171 so that the latter may rotate without interfering with them. The disks 182 are open at the center to admit inwardly projecting springeretaining pressure cups 183, 184:. The said cups are provided with annular shoulders 185, 186, which bear respectively against the cap plates 180, 181, and at their outer ends with flanges 187, 188, which are littedto slide within the drums 173, 17%.

Coiled springs

189, 190, are seatedrespectively in,- the cups 183, 181, their inner ends aring against the bottoms of the'cups and their outer ends against plates 191, 192, which are fitted to slide in the outer ends of the drums 1'73, 174. Pins 193, 194:, pass through the plates 191, 192, and flanges 187, 188, and are made fast ,in the flanges 177, 178, of the drum to hold the said plates and spring retaining cups against rotation rela-' tive to the drums, while permitting the said provided with a collar 198 against which the inner face ofthe plate 191 bears, and a pin l99,'fiXed in the plate 191 extendsalong a groove in the collar 198 to prevent the rod 195 from. rotating relatively to the plate In operation, the plate 191 having been adjusted against the collar 198 and the nut 196 screwed on against the outer face of the plate, the desired tension may be applied to the rotary cylindrical shell 167 and its gear 165 by turning: on the nut 197, thereby drawsaid hubs serving as supports for a series of I ing the plates191, 192, toward each other rods 170, in the present instancesix, at'equal The rods 170 support a and, through the medium of the

springs

189, 190, pressing

thecups

183, 18%, toward each other and hence the end caps 180, 181, and the disks between them into closer frictional be communicated through the

gears

165, and 166, to the evening rolls. and hence to the threads passing around them. Tension may. be relieved at any time by simply unscrew ing the nut 196 and the exact former tension restored by screwing the nut 196 on until the plate 191 bears against the collar 198, the nut 197 remaining undisturbed.

Take-up mechamlsm.Each shed of warp passes from anevening roll over a guide roll 200 mounted in suitable hearings in a bracket 201 secured to and projecting outwardly from the pillars 4, the same bracket forming a support for the heddle guides 132, 133, heretofore referred to. The threads as theyextcnd upward from the evening rolls are separated by the fingers 202 on av bar 203carried at the lower part of the bracket 201 and thence each thread passes in front of a series of bars 204 the present. instance four bars, and through loops or eyes 205 interposed between the bars 204v and attached to 'a swinging ar'm 206 mounted on a rod 207 carried by the bracket.201.. The arms 206, one for each thread, work independently of one another, and each is under the tension of a spring 208, attached at one end to the arm and atthe opposite end to a rod 209 held in arms 210 depending from a sleeve 211 mounted on a rod 212 carried by the bracket 201. The sleeve 211 is held in the desired rocked adjustment on the rod 212 by a set screw 213, to give the proper tension to the spring 208 to draw the take-up arm 206 back whenever the thread slackens, as during the crossing of the warps at each pick. If a warp thread breaks, the

arm 206 is rocked back against a stop rod 214 as shown in dotted lines Fig. 6. By multiplying the number. of bars 204 and alternating loops or eyes 205, the slack is promptly taken up by a slight movement of the take-up arm and the thread is moved but little out of its normal course at any one point.

Take-off rolla-The take-off rolls 215,216 (see Figs. 1 and 2) are mounted in hangers depending from rock shafts 21.7, 218,

'mounted in the ends of a housing 219 at the middle portion of a bracket 220 removably bolted to the cap late 5. One pair of these hangers denoted y 221, 222, is shown in Fig. 1, and it is to be understood that a pair of similar hangers depend from the shaft 218 to support the roll 216. One of the rolls, in the present instance-the roll 215, Y is mounted in yielding bearings 223,- 224, of any suitable construction, to permit it to move away from its companion-rolls in the event of any slight'abnormal increase in the thickness of the woven tube, The rock shafts 217, 218, have inter-engaging toothed sectors .225, 226, fixed thereon so that the rocking movement of one shaft-twill be communicated to the other and cause the

rolls

215, 216, to simultaneously move toward or away from each other depending-upon the direction in which thefshaft is rocked. A spring lever 227 is attached at one endIto; the shaft 218 and near its opposite, or handle end, it engages in some one of a

series of'iiotches

228 or 229 to hold it and hence thetake-ofi rolls in the desired adjustment toward or away from eachother.

The

rolls

215, 216, are positively driven by means of

shafts

230, 231, provided withl the usual universal-couplings and with

worm wheels

232, 233, engaged by a worm 234 on an upright shaft 235, which shaft is provided with a hand wheel 236 and is adapted to be connected with the driving mechanism,

by a sliding clutch 237 operated by a handle 238 pivoted on a bracket 239 and connected with the clutch by a connecting rod 240. The bracket 239 is attached'to the 'cap plate 5 and supports the shafts 230,- 231, and guides the upright shaft 235.

The driving mechanism.-The loom frame is, fitted to receive a suitable support for an electric motor 241' which transmits its power through a belt. 242 to a pulley 243 on the outer end of a main drive shaft 244. The shaft 244 is mounted in suitable bearings in a bar frame 245 secured. on the base 1. A bracket 246 is removably secured to the outer face of the box frame 245 to fori'na rest for the lower ends of two

outer standards

247, 248, and two shorter inner strut} ards 249., 250, rest on the cap plate These standards are connected by head frame 251 on which the motor frame is secured. In the event some other source of power other than eleetric is to be employed, the standards and their head frame and supporting bracket may be removed and a driving belt may be led from such' other source of power to the pulley 243. The loom is thus adapted to use in connection with water, steam, electric or other power, without disturbing its in tegrity.

The main drive shaft 244 carries on its inner end a bevel gear wheel 252, which intermeshes with a bevel gear wheel 253, on an upright shaft 254, stepped in a bearing 255- on .the box frame 245. The upper end of the shaft 254 is mounted in a suitable bearing in the table 3 and said shaft has a driving pinion.256 fixed thereon which intermeshes with the master gear wheel 21 hereinbefo're referred to. This affords a direct drive from the upright" shaft, to the master gear which in turn directly engages pinions 257 on the several upright shuttle driving spindles 258.

These shuttle driving spindles are each pro vided with a drive inion 259 which engages the rack 65 carried by the shuttle. The said spindles are also each provided with a roller 260, immediately above the drive pinion, in

position to bear against the broad rim 66 on the shuttle, hereinbefore referred to. I rollers 260 are made of rawhide or other suitable noise reducing material and roll on the spindle independently of the pinions to prevent any drag which would result from The the bearing face of the rim 66 being out of Y i the pitch line of the intermeshing gears 65 and 259.

The spindles 258 on which the

pinions

257 and 259 are carried, consist of round rods to which the hubs of the pinions. are locked by means' of keys having heads 257* for laid and the action of screwing it up toward the previously laidgveft thread has begun. This action is shown progressively in the following figures, 39, 40, 4:1, 42, the lay holder vanishing as the trailing end of the the evening rolls and when so used the evening rolls and their supporting ring may be bodily removed from the loom frame.

, As the .weaving may take place either about a ring or weaving pin, as in weaving a tubular hose, or about a hose or wire, as in weaving a hose covering or insulating a wire, I have chosen the word core to cover generically all these forms about which the weaving'may take place.

\Vhat I claim is 1.,.. In a circular loom, the combination with means-for manipulating the warp threads, a core. about which the weavin takes place and means for directing a we t thread into operative relation to the warp threads at the periphery of the core, of a traveling wedge in position .to force the weft thread against a previously l aid weft thread.
