SWIVEL-Loom.

SPECIFICATION forming part of Letters Patent No;.753,741, dated March 1, 1904. V

Application mea nach 2e, 1902.

To all whom, ill/may concern:

Be it known thatLEPrA H.RYoN,a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massa- 5 chusetts, have linvented certain new and usefful Improvements in Swivel-Looms, the following is a specication. v

My invention relates to swivellooms in which, in addition to the ordinary y-shuttle for weaving the body of the fabric, one or more sets or series of swivel-shuttles arranged in parallel rows are used to weave spots or small gures on the face of the fabric, the swivel-shuttles being supported over the raceway on the lay and positively raised and lowered at the proper time from below and each set of shuttles moved transversely of the fabric independently and all the sets of shuttles moved simultaneously transversely of the fabric on the transverse movement of the swivelshuttle rail. v

The swivel-loom to which my improvements particularly relate is shown and described in United States Letters Patent No. 624,039, dated May 2, 1899, to which reference is hereby made. yIn said patent the well known Knowles harness-shedding or shuttle-boX-operating mechanism described in United States Letters Patent No. 134,992, of January 21, 1873, is used .for operating the swivel-shuttles, and in said patent the shuttle-rail carrying the swivel-shuttles can have only two positions transversely of the fabric. In my improvements I provide mechanism in place of the Knowles shuttle-boX-operating` mechanism of said patent for moving the swivel-shuttles, and I provide mechanism for operating the sliding-pick mechanism (which controls the action of the fly-shuttle median-- ism) and mechanism for raising and lowering the swivel-shuttle rail carrying the swivel` shuttles different from the mechanism for the same purpose shown and described in said patent. I also provide mechanism for mov- 45 ingy the swivel-shuttle rail and the swivelshuttles transverselyof the fabric,l by which the swivel -shuttle rail may occupy the two eXtreme positions, -asin said patent, and also of which Serial No. 100,081. (No model.)`

any intermediate position, which cannot be done on the loom shown and described in said patent. j y

My invention consists in certain novel features of construction and certain novel combinations .of parts of my improvements in swivel-shuttle looms, as will be hereinafter fully described. y

I have shown in the drawings only such portions of a iiy-shuttle loom with my `improvements applied thereto as will enable those skilled in the art to which my invention belongs to understand the construction and operation thereof.

I have not shown in the drawings the sliding-pick mechanism for controlling the action of the fly-shuttle mechanism, as the same may be of any ordinary and well-known construction ordinarily used in swivel -looms of the class above referred to-for example, the sliding pick mechanism shown and described in United States Letters Patent No. 474,170, of May 3 1892. ,y

Ihave shown in the drawings three sets or serlesof swivel-shuttles arranged in three parallel rows on the swivel-shuttle rail. Each set of swivel-'shuttles is operated by independent mechanism controlled by the jacquard or pattern surface; but as the mechanisms are of the same construction and operation I have only shown in the drawings and described herein one of the mechanisms for operating the swivel-shuttles.

Referring to the drawings, Figure 1 is a side or end elevation ofl a portion of a loom with my irmarovements applied'thereto looking in thedirection of arrow c, Fig. 2. Fig. 1n is 'a detached plan view of parts shown at the left in Fig. 1, connected :with the sliding-pick mechanism (not shown) and taken at al point indicated `by line l la, Fig. 1, looking in the direction o f arrow Z2, same figure.' Fig. 2 is a front elevation of myimprovements shown in Fig. 1 looking in the direction of arrow c, same figure. Fig. 2 is a detached Vplan view of some of the parts shown at the left and in the upper part in Fig. 2 looking in the direction of arrow al, same figure. Fig. 3 is a dei tached view of some of the parts shown in Fig. 1 in adifferent position. Fig. 4 is a plan view of the parts shown in Fig. 3. Fig. 5 shows a pin-wheel and segment star-wheel detached. Fig. 6 shows a rack-bar shown in Fig. 3 detached. Fig. -7 shows a modified construction ofthe rack-bar shown in Fig. 6; and Fig. 8 is a cross-section on line 8 8, Fig. 4, looking in the direction of arrow e, same figure. Figs. 3 to 8, inclusive, are on an enlarged scale.

In the accompanyingdrawings, 1 is the loom side or frame; 2, the breast-beam; 3, the lay; 4, the lay-swords, attached at their .lower ends to the plates 4', mounted on the shaft 4". The lay-swords 4 have the upwardlyextending lay-sword horns 4'.

5 is the crank-connector, which connects the lay 3 with the crank-shaft 6.

7 is the bottom or driven shaft, which is geared to the crank-shaft 6 through gears 8 and 9. (Shown by broken lines in Fig. l.)

All of the above parts are of the ordinary construction. i

On the bottom shaft 7 is arcam 10, which has a grooved track 10' on one side, in'which travels a pin or yroll 11f on the lever 11, pivoted at its lower end on a stud 12 on the frame 1. The upper free end of the lever 11 carries a pin or roll 11, (see Figs. 3 and 4,) which engages a vertical groove 13 in the verticallyextending extension 13" on the horizontal reciprocating bar 13. The ends of the bar 13 are guided in grooves or ways in the offsets 14 on the stand 14,secured to the loom-frame 1.

The bar 13 has -a side extension 13 extending out at right angles therefrom. (See Fig. 4.) i

The cam 10 rotates `with the bottom shaft 7 and operates, through the lever 11, to cornmunicate a reciprocating motion to said bar 13 in a horizontal plane. The extension or arm 13' on the bar 13 has a free passage through thehorizontal slots 15 inthe three plates l5, 15", and 15", which plates are pivotally mounted at one end on a stud 16, fast in the stand 14, bolted to the loom side. (See Fig. 4.)

AThe plates 15, 15", and 15" each have opposite side extensions 15l at their pivotedends, which extensions are bent'at their ends to enter and engage ways `or recesses 17"'inthe sides of the toothed bars or racks 17, 17", and 17". In the plates 15, 15", and 15" at their free ends and parallel to the central slot 15 and on each side of said vslot is the slotj15, in which travels the offset projectionsor key 17", 17", and 17" on the racks 17, 17", and

17", respectively. The slot 15' is enlarged at one end, as shown in Fig. 8, to permit the entrance through the slot of the key 17 17", and 17" on the racks 17 17", and 17", which ,key has an overhanging outerv edge or lip to engage the plate and hold the racks in position adjacent to the plate. The free ends ot' the plates 15, 15", and 15" are guided between the upright teeth 18 on a comb 18, fast to the stand 14.

The lower end of a iiexible connector 2O (see Fig. 1) is attached to the free end of each plate 15, 15", and 15", and the upper end of said connector is connected with the jacquard or other pattern-indicating mechanism (not shown) for the purpose of raising the plates 15, 15, and 15" when desired.

I will first describe the mechanism connected with the outer plate 15, Figs. 1, 3, and 4, the raising and lowering of which plate at its free end, (by the connector 20, according to the indications of the pattern-surface,) through intermediate mechanism, controls the operation of the sliding-pick mechanism, (not shown,) which controls the action of the flyshuttle mechanism and also controls the operation of the mechanism for rai'singand lowering the swivel-shuttle rail and swivel-shuttles at the proper time.

The two racks 17 connected with the front plate 15, as above described, have al reciproeating motion in a horizontal plane simultaneously in opposite directions through the 'arm 13 on the bar 13, which extends freelj7 through the slot 15 in the plate 15 and engages a projection 17 on the upper or lower rack 17 (see Fig. 3,) according to whether the plate 15 is in its raised or lowered position at its free end.

The teeth o n each rack 17 mesh with the teeth of a pinion 21, (not shown,) loose on the stud 16, to operate said `pinion first in one direc'tion and then in the other. Connected with the pinion 21 is the mutilated pinion 22, (see Fig.'3,) and between the pinion 21 and the pinion 2,2 is a thin disk 23, which operates to guide the toothed ends of the racks 17 and prevent their engagement with the partial or mutilated pinion 22. f

The pinion 22 has a dwell portion 22thereon adapted to engage the concave recess inthe partial or mutilated segment gear 24, loosely mounted on a stud 25, fast in the stand-14. (See 3.) An offset tooth 22 on the outer face ofthe pinion 22 is adaptedto engagean offset tooth 24 on the outer surface of the segment-gear 24 to start the rotationof the gear 24 when the pinion 22 revolves in the direcvtion of the arrow Fig. 3, and thcv engagement of the teeth on the pinion 22 with the teeth on the segment-gear 24 completes-the partial rotation of the segment-gear 24 to move it from the position shown in Fig.v 3fto theposition shown in Fig. 1. 4 i

A lever or arm 26, mounted onthe stud 25, is secured to the segment-gear 24 to move with it by a screw 26. (SeelFig.v` 3)4 The` outer end of the lever 26 has a slot 26: therein, which is connected by a bolt 27 with one end IOO IIO

of the connector 27 (See Fig. 1.) The other,

end of lsaid connector 27 is pivotally connected to one arm 28"(see Figi 1") of an angle-lelever 28, pivotally'mounted ona stud-29 on a into which loosely extends and travels a pinv 31 on the collar' 31, fast on the shaft or rod 32.

l -The movement of the anglellever 28 on its pivot-'stud 29 by the connector 27, through thei partial rotation of the segment-gear 24,

above'gdescribed, will' cause the shaft 32 to ,l have a'motion in the direction of its length.

'1o The shaft 32 is connected with the slidingpick mechanism, (not shown,) which controls the action of the y-shuttle mechanism, which,

as above stated, may be of the construction andoperation showny in United States Letters PatentNo. 474,170 o r of any other usual construction. l j f It'will be seen in Fig. 3 that the arm 13" on the barl3, through the operation of the cam 10 and the lever' 11, has been'moved to its zo extreme forward position or its eXtreme position to the right, and the lower rack 17 by engagement of the arm 13l with the projection 17 on said rack hasalso beenmoved to its extreme forward yposition or its extreme position to the right, Fig. 3, the plate 15 beinginits raised position at its free end to lcause thearm 137 `on ythe bar 13 to engage the projection 17 on the lower rack 17 and 'cause said rack to move with-said arm 13".

The movement of the rack 17 t'o the position vshown in Fig. 3 has ,caused the pinion 21, v partial pinion 22, and the segment-gear 24 to move to the position shown in Fig. 3 and also caused the upper rack 17 to be moved to its eX- 3 5 treme outward position.

' In the continued revolution of the cam 1() through the lever 11 the arm 13lll on the horizontalbar 13 will be moved to the left, Fig. 3-`that is, from the position shown in Fig. 3 tothe position shown in Fig. l-leaving the lower rack 17 stationary, and consequently the pinion 21, partial pinion 22, andthe segmentfgear 24 and parts operated thereby. If lon the following pick or any succeeding pick ,it i s desired to again rotate Athe partial gear 24 and move 'it'into the position shown in Fig. 1 to operate the sliding-pick mechanism,

an indication of the jacquard or `other pattern-indicating mechanism through connector i 5o 2() will cause the plate15 to Vbe lowered at its free end and bring the upper rack 17 in such a position that the projection i 17 thereon will beengaged bythe arm 13" on the bar flhemovement of the bar 13 forwardly, fthe right, will cause the upper rack 17, IFig. 3`, to be moved to the right, and, through its vengagement with lthe pinion 21, rotate said pinion andthe pinion V22 in the direction of arrow 06,;Fig. 3, to move the segment-gear24 l 'from' the position shown in Fig. 3 to the position shown in Fig. 1 and operate, through intermediate connections, the shaft 32.

I will now describe the mechanism in this instance connected with the shaft or rod 32 and l operatedby' the'movement of said shaft 32 to their connections vthe swivel-shuttle rail and positively raise the swivel-shuttle rail and swivel-shuttles and hold them in their raised position during the operation of thefly-shuttle and to lower the swivel-shuttle rail and swivel-shuttles into operative position when 7.o the iiy-shuttle is not inl operation. I On the end of the shaft 32 is fast a collar`33, (see Fig. 1",) having a pin 33 thereon, to which is pivotally connected one end of a connector or link 34. The other end of said connector 34 7 5 is pivotally connected with a pin 35,fast in the armY 35" of the angle-lever 35, the hub of which is loosely mounted on a studf36 in the stand 36, secured to the frame,J (See Fig. 1.) The other arm, 35', of the angle-lever 35 is 8o pivotally connected at its end by a pin 37 to the upper end of the connector or link 37 The lower end of said connector 37 has a slot 37 therein, through which extends loosely a pin 38 on the outer end of a lever 38, fast on 8 5 a rock-shaft 39, mounted in-a stand 40, secured to the frame. (See Fig. 1.) Also fast on the rock-shaft 39 is one end'of the lever 41, which has a pin 41' thereon at its other end,

to which is pivotally connected the lower end 9o of the connector 42.' The upper'end of the connector 42 is connected bya stud 43 with the end 'of a crank-arm 44, which is fast on a rock-'shaft 45, which extends transversely across the loom and has bearings in the stands 9 5v -46, secured to the front of the lay-swords-in Fig. 2.

Fast on the'rock-shaft 45 are the inner ends of the two vcrank-arms 47, (see Fig. 2,) which are forked at their outer ends and carry a pin 47', (see Fig. 1,) on which are pivotally mounted a plate or coupling 48, into which is screwed the lower end of the upright rods 49,v which at their upper ends 49' pass loosely through a guide-plate 50, secured to each lay-sword horn 4. (See Fig. 2.) Onthe upperj'part of each rod 49 is a Vplate 51, heldin Vposition by collars 52 above and below the plate l51. On each plate 51 are hub- like extensions 51 and 51, and in the lower hub, 51, is loosely. mounted a sliding rod 53, the inner end of which is fast in the hub 54 on'a stand 54, securedto the upper side of the shuttle-rail 55. A rod 56 extends parallel to the rods 53 and lis loosely mounted in the'hubs 54l on the 115 standy 54`and is secured at its ends in the hubs 51" of the platesv 51 (see Fig. 2) and acts to hold the swivel-shuttles in proper position.

On the stud 43, which connects the upright connector 42 with the crank 44 on the lrockshaft 45, is loosely mounted a roll '57, which travels on a cam-surface 58, secured to the loom-frame, (see Fig. 1,) sor that on the beating-up of the lay the rock-shaft 45 will be rotated, and Vthrough the upright rods 49 and IOS IIO

swivel-shuttles will be positively raised outof the shed. Y f, A

I will now describev the operation of the mechanism above described for raising and 130 lowering the swivel-shuttle rail and the swivelshuttlescarried thereon.

As shown in Fig. 1, the lay is in its rearward position and the swivel-shuttles have beenlowered intothewarp. (Not shown.) The movement of the shaft 32 by the mechanism above described in the direction of the arrow f, Fig. 1, will, through link 34, move the angle-lever 35 and cause the connector 37, attached to the end35"l of said angle-lever, to move downwardly in the direction of arrow Fig. 1, and with it the lever 38, fast on the rock-shaft 39, to rock said shaft 39 and cause the lever 41, also fast on the shaft 39, to be moved upwardly and the connector 42 to be moved upwardly to raise the crank-arm 44 to rotate the rock-shaft 45. The rods 49, through the forked crank-arms 47, are also moved up'- wardly to move the plates 51 in 4their guideplates 50 and raise the swivel-shuttle rail 55 through the rods 53, mounted in the hubs 51' on the plates 51 and fast in the hubs 54 on the stands 54, secured to the shuttlerail. The movement of theshaft 32, Fig. 1, in the opposite direction or the direction of the arrow It, same figure, will,through the intermediate mechanism above described, lower the swivel-shuttle rail and the swivel-shuttles into operative position. (Shown in Figs. 1 and 2.)

I have shown in the drawings three sets orv series of swivel-shuttles arranged in parallel rows, and I will now describe the means for operating the separate sets orseries of shuttles to communicate a reciprocating motion thereto and carry them across the openings between the blocks on the under side of the shuttle-rail in the usual way.

The mechanism for operating each set of swivel-shuttles isthe same-that is, they are duplicates of each other-and therefore it will only be necessary to describe one of the 4mechanisms. There is aplate 15, (see Fig. 4,) which corresponds to the plate 15, above described. There are two racks 17 a, similar to the racks 17, above described, except that the projections 17' are on the eXtreme ends of the racks 17 a, as `shown in Fig. 6, and are engaged by the rear edge of the arm 13' on the bar 13." The racks 17 engage the teeth on a pinion 21, (see Fig. 8,) loose on the stud 16 and fast to a pin-wheel 60,'also loose on said stud 16. rIhe pin-wheel 60 has a pin 60', which is wheel 61 is pivoted the upper end of the connector 62. (See Fig. 1.) The lower end of said connector 62 is pivotally attached to one end of the lever 63, centrally pivoted on a stud 64 on a'stand 65, secured to the loom-frame. The opposite end of the lever 63 is pivotally attached to the lower end of an upright rod 66. (See Fig. 1.) 4The rod 66 is shown broken away at. its upper part. The upper end of said rod 66 is pivotally attached to one end of an angle-lever 67, (see Fig. 2,) mounted on a studl 68,4fast in the upper end of a sliding plate 69, which has a rectangular slot therein and is mounted `on the arm 50 on the guideplate 50 (see Fig. 1) to move with said plate 50 and to havea movement in a horizontal plane on the arm 50 independent of the movement of said plate 50. To the other arm of the angle-lever 67 is pivotally attached one end of a connector 70. The other end of said connector is attached to the sliding bar 71, guided in the plate 72 on the swivel-sl1uttle rail, and connected with a rack engaging pinions (not shown) to move the swivel-shuttles 73 to the right and left across the opening 74 between the block 75 on the under side of the swivel-shuttle rail 55 in the usual way and as fully shown land described in Patent No. 624,039, above referred to.l It will be seen that when the plate 15 is moved into its raised position by the connector 20 the arm 13"' will engage the projection 17 on the lower rack 17 l and move said rack to the left, Fig. 3, to cause it to rotate the pinion 21HL and the pin-wheel 60 and move the segment starwheel 61 from the position shown in Figs. 3 and 5 to the position shown in Fig. 8, and through the intermediate connections from the star-wheel 61 to the set of swivel-shuttles connected therewith move the set of swivelshuttles to the left in Fig. 2. When the plate 15 -is lowered, then the arm 13" on the bar 13 will engage the projection 17m" on the upper rack 17 a, as shown in Fig. 8, and move said rack and through the pinion v,21" and the pinwheel 60 move the star-Wheel 61 from the position shown in Fig. 8 to the position shown in Fig. 3and throughintermediate connections move the swivel-shuttles in the opposite direction or to the right in Fig. 2. Each row of swivel-shuttleswill thus be independently moved according to the indications of the pat-v tern-surface, which control through connector 20 the raising and lowering of the plate 15".

In addition to the raising and lowering of the swivel-shuttle rail and the swivel-shuttles and the independent movement of each set of swivel-shuttles the swivelzshuttle rail and all the swivel-shuttles may be simultaneously moved transversely of the warp-threadsgto their eXtreme end positions or to intermediate positions. i

' I will now describe the mechanism for mov.- ing the swivel-shuttle rail and the swivel-shuttlestransvfersely` of the warp-threads.

The plate 15P, Fig. 4, corresponds to the plates 15 and 15, above described. A pinion 2lb is loosely mounted on the stud 16 and is engaged and rotated bya rack-bar 17", which IOO IIO

in this instance corresponds to the lower rack 17 and 17 a, above described, except that it has two projections 17 b" (Shown in Fig. 7.) An upper rack is not used iny this instance with the plate 15b. The arm 13" of the bar 1.3 engages a projection 17W on the rack 17b on its forward or backward stroke. The pinion 21]D is fast to a pinion 22h, loose on the stud 16, and a disk 23"y extends between the pinions 2lb and 22". The pinion 22h is similar to the pinion 22, above described, except that the dwell 22 on the pinion 22 is not required. The pinion 22b is in mesh with the teeth on a partial or segment gear 81, loose on the stud 25 and having the Slotted arm 81', to which is pivoted the lower end of the connector 82. (See Fig. 1.) The upper end of the connector 82 is pivotally connected to the slotted end of the lever 83, pivotally supported on a stud 84. On the extreme end iof the lever 83 is pivotally mounted the lower end of a pawl 84, held by a spring 85, attached to the pawl 84 and the lever 83 in engagement with the teeth on the ratchet-wheel 86. (Shown by broken lines in Fig. 1.) The ratchetwheel 86 is loosely mounted on a stud 87 on the loom-frame and has attached thereto a gear 88, the teeth of which engage the teeth of the gear 89, loosely mounted on a stud 90 on the loom-frame. Fast to the'gears 88 and 89 are the pattern disks or surfaces 91 and 92, having in this instance removable pattern-pins 91' and 92', extending out from their peripheries and forming pattern-indicating surfaces to control through intermediate mechanism the longitudinal or transverse motion of the swivel-shuttle rail and swivel-shuttles. The projecting ends of the pattern- pins 91 and 92 are adapted to engage the upper and lower inclined edges of the diamondshaped cam 93, fast upon the inside of the upright movable bar 94. Said bar 94 has vertical slots 94 therein, through which the studs 87 and 90 loosely extend, and collars 95 on said studs hold the upright movable bar 94 in proper position as it is raised or lowered.

, As a check device for holding the ratchet- Wheel 86 and gear 88 after each partial revolution a roll 96, mounted on a stud on the free end of the lever 97, pivoted on the loomframe at 98, extends into a recess in the periphery of the disk 99, fast to the ratchet 85. A spring 100, attached at one end to the lever 97 and at its other end to the frame, acts to hold the roll 96 in engagement with theperiphery of the disk 99 (shown by broken lines in Fig. 1) to hold said disk and the ratchet after each partial rotation thereof. -Y

Attached to the lower end of the verticallymovingv bar 94 isa connector 101, which is inwardly bent, as shown in Figs. 1 and 2, to avoid contact with the other parts. The lower end of the connector 101 is attached to one end of a lever 102, centrally pivoted on the stud 64. The other end ofthe lever 102 is pivotally attached to the lower end of the upright rod 103. The upper end of said rod 103 is pivotally attached to the forked end of a link 104, as shown in Fig. 2. The upper endv of the link 104 is connected with the slotted arm 105 of the angle-lever 105, which is pivotally mounted on a stud 107 on the arm 50", extending from the side of the guide-plate 50. The other arm of the angle-lever -105 carries a pin or roll 106, (shown by dotted lines in Fig. 2,) which travels in a vertical slot 108 in the plate 108, fast on the outer end of the rod 53, loosely mounted inthe hub 51 on the plate 51 and secured at-its end in the hub 54 on the stand 54, fast on the swivel-shuttle rail 55.

I will now describe the operation of the mechanism above described for moving the swivel-shuttle rail and the swivel-shuttles transversely ofthe fabric.

The plate 15D is raised or lowered by the connector 20, according to the indications of the jacquard or other pattern surfaces, and the rack-bar17bis moved by the arm 13 on the horizontally-moving bar 13 in one direction or the other to rotate, through pinion 21b and pinion 22h, the gear-segment 81, and throughy connector 82 and lever 83 move down the pawl j A 84 to rotate the ratchet-wheel 85 and gears 88 and 89 and pattern- disks 91 and 92. The rotation of the disks 91 and 92 causes the radial pins 91 and 92 thereon to engage the opposite peripheries of the cam 93 on the upright bar 94 and cause said bar to be raised or lowered. The length of the radial pins 91 and 92 vary; but the total length of any two pins operating at the same time upon the cam 93 will equal the total possible amount of lmovement given to the bar 94. The vertical movement of the bar 94 operates, through connector 101, lever 102, and lupright rod 103, to move the lever 105 and through the plate 107 and rod 52 move the shuttle-rail 55, carrying the swivel-shut-l tles transversely or to the right or left, as desired, according to the length of the patternpins 91 and 92. When the shuttle-rail 55, carrying the swivel-shuttles, is moved transversely in the direction of its length, it is necessary that the other parts, and particularly the stud 68, on which the lever 67 is miounted, should move with it, and therefore a connector 109 is pivotally attached at one end to the `sliding plate 69 (see Fig. 2) and at its other end to a stand .110, fast Vto the upper side of the shuttle-rail. Y

It will be understood that the details of construction of my improvements may be varied, if desired, and-my improvements may be applied toly-shuttle looms of ordinary construction and made to cooperate with the usual operating mechanism of such looms.

Having thus described my` invention, what I IOO IIS

IZO

claim as new, and desire to secure by Letters l a set of swivel-shuttles transversely of the fabric, comprising a lever or plate, adapted to be moved, through connections to a jacquard or other pattern mechanism, two toothed bars or racks connected to said plate and moving therewith, and moved independently of said plate, and means for moving said racks simultaneously in opposite directions, a pinionV meshing with and moved by said racks, and connections intermediate said pinion and the swivel-shuttles, substantially as shown and described.
