Fig. 2 is a transby said hub K is a movable stud or piece K, I00 50 verse section of the shaft that operates the one end of which rests within an inclined loom-head at line m 00, Fig. 1. Fig. 3 is a groove J in the top end of the sleeve J, while its other end supports the sliding collar l... The tlange j of the sleeve .1 and the llange 7; of the hub K stand adjacent to each other and are perforated to receive a pin 1, (one or more, if desired) which is inserted therethrough, as indicated, for making the power connection between the clutch and shaft and transmitting the rotative force for driving the shedding mechanism or loom-head, while the clutch 71 can be thrown into and out of action, as desired, without interfering with the pin, the action being the same as with a simple clutch, so long as the pin P remains intact. Said pin P is of such size that it will transmit the requisite power for the ordinary working of the loom, but not so large but that it will give way or become sheared off in the event of any undue or severe resistance or accidental catch in the action of the shedding mechanism. The flangesj and 7.1 are best provided with hardened-steel dies 1" fitted therein (see Fig. 10) for receiving the pin I, and which facilitate the shearing off of said pin without damage to the edges of the opening wherein said pin is inserted. The pin can be an ordinary split pin or a piece of bent wire, so as not to be liable to escape from position. An angle-lever M, fulerumed on an arm of the frame at M, engages with the sliding collar L by its end resting on the collar-flange or in other suitable manner. Said lever has its opposite arm connected by a rod M with an arm or level-m, that is fixed on the end of the rocker-shaft N, by which the shipper is operated.

Iivoted on the forward part of the frame is a hand-lever n", which engages with the end of lever m by suitable gear-teeth. The shaft N extends across the breast of the loom and is provided with a crank or arm N for working the shipper-rod N and clutch V, which lattercan be of the usual well-known kind. The connection between the arm N and rod N I construct as shown in Figs. 5 and U. A pair of knuckle-joint arms not connect the rod N with a stud u", that is fixed in the frame A, and a link or bar N connects the central hinging point of said knuckle-joint with the crank N of the rocker-shaft N, so that movement of said shaft straightens or bendsthe knuckle-joints, operates the rod N and throws the driving-clutch V into or out of engagement, as required. The rockershaft Nand shipper are thus conveniently operative either by means of the hand-lever a or by the throw-01f of the relief mechanism.

In case of any derangement or failure to properly operate in the vibrators and shedding mechanism, which would occasion a stoppage in the action thereof and be liable to break the machinery, the strain is relieved by the breaking or shearing off of the pin 1, and when such shearing action takes place the shaft G is released and stops, while the sleeve K continues to revolve and the inclined surface J 2 forces upward the stud K, which in turn lifts the collar I1 and end of the angielever Sheausing a backward draft upon the rod M which works the rocker-shaft and shipper mechanism, and thus throws otf the clutch and immediately stops the entire loom.

I am aware that a relief and throw-off device, in combination with the head-operating shaft in a loom, has been described in Letters Patent heretofore granted, but of a construction and manner of operation essentially different from that herein specified and claimed.

Another feature of my invention consists in providing beneath the outer end of the vibrator-bars an eccentrically pivoted bar R, that extends across the space beneath the vibrators, and has its end pivots supported in suitable bearings preferably attached to the guide-bar '1. (See Figs. 1, 7, and 9.) Said bar R is provided with an outwardly-extending arm 0', by depressing which the inner edge or eccentric portion of the bar is turned upward beneath the ends of the vibrator-bars, thereby simultaneously lifting all of said vibratorbars so as to bring their crank-gears F into engagement with the cylinder-gear G. Then by turning said eylinder-gear a (piarter-revolution by means of the hand-crank 0 all of the jacks 13 and harnesses are brought into line, or even with each other, so as to close the shed to facilitate repairs in any breakdown of the warps, or for any other purpose, as desired. By returning said eccentric-bar to its normal position the vibrator-bars are immediately again thrown onto the control of the pattern-chain D which is of wellknown kind and operation. The eecentrieallypivoted bar serves as a fall-stop for the end of the vibrator-bars and also as a lifter for simultaneously elevating all of the vibrators into engagement. In the present instance, and preferably, two of these lifting fall-stop bars are employed, one for the vibrators,which control the harness-jacks, and one for the vibrators that control the shuttlebox-actuating jacks. The guide-bar T is pivoted at its ends in the frame A,so as to swing outward and downward to facilitate removal of the vibrator-bars, and is held in upright position by bolts a, that connect its upper part with the frame, substantially as described in my previous patent.

The dogs I forloeking the vibratoror crankgears F are made substantially as indicated in Fig. 7. The dog slides longitudinally on the vibrator-bar and is provided with a spring 1', the ends of which are secured to the projecting ears of the dog, and the center of said spring is made with a downward point or curve adapted to engage in a notch formed in the upper side of thcvibrator-bar, as illustrated, whereby said dog is retained when in normal position.

The retractor 8 is provided on its shaft with u p wardly-proj ectin g ears (hand the actuating arms 10, that work in connection with the cams c on the cylinder-gem axle, are arranged to slip over the axle or shaft of the retractor and have backwardly-projectin g slotted arms that respectively match against and are bolted to the ears 9 on the retractor-shaft, as indicated, whereby the position of the arms 10 in relation to the retractor-bar can be conveniently adjusted to bringthe engaging dogs of the retractor-bar accurately into place in relation to the notches of the dogs.

The retractor-bar, in accordance with my present invention, is provided with a movable engaging plate 11 along the face thereof, which plate is provided with a series of inclined slots, through which the attaching bolts or screws are arranged, as at 12, so that longitudinal movement of said plate will raise it from engagement with the dogs. This movable plate 11 facilitates the removal of any of the vibrator bars and dogs from the loom, since it can readily be raised from engaging position. Longitudinal movement of the engaging plate in opposite direction lowers it to its normal position. The plate is best provided with a suitable grip-handle and looking device 13 to facilitate moving it and for retaining it at normal position.

The movable engagingplate 11 for that part 18 of the retractor that controls the dogs of the sh uttle-box-operatin g mechanism can be made as shown atthe rightin Fig. 8, viz: with an upright slot and set-screw 15 for affording adjustment instead of the diagonal slots. The part 18 of the retractor, which controls the shuttle-box operating mechanism, is fitted as a sleeve or auxiliary upon the axle of the main retractor 8, and is supported thereon in a manner tohave independent movement, the same being provided with arms 10, that engage auxiliary cams on the cyl'inder-gearaxle for effecting action of said auxiliary retractor independently of the main retractor that controls the dogs of the shedding mechanism.

The arrangement of the harnesses with the swing-jacks, the pattern-chain D its rotator, and operating-gearing for intermittently advancing the same can be of well-known kind and the general operation of such mechanism similar to that heretofore employed.

I claim as of my invention, to be herein secured by Letters Patent 1. The combination, with the head-operating shaft that transmits power to the shedding mechanism and its operatin g-gearin g and clutch, of the flanged sleeve mounted loose on said shaft and supporting the clutch-ring, the flanged hub fixed on the shaft, and the pin P, arranged through the flanges of said sleeve and hub and forming the power-transmitting connection, substantially as and for the purpose set forth.

2. The combination, with the shedding mechanism, its operatingshaft, operatinggear, and clutch, of the loose sleeve J, carrying the clutch-ring h and provided with an inclined surface J a hub fixed on said shaft adjacent to the said sleeve, having a movable stud arranged therethrough, the relief-pin P, connecting said hub and sleeve, the sliding collar mounted to slide on said shaft and supported on said movable stud, a lever, as M, one arm engaging with said sliding collar and its other arm connected by a rod, and suitable gearing with the shipper'actuating mechanism of the loom, substantially as and for the purpose described.

3. The combination, with the head-operating shaft and shedding mechanism in a loom, of the flanged sleeve J, the flanged hub K and relief-pin P, and the cutters or dies P inserted in said flanges for supporting said pin.

a. The combination, with the frame, cylinder-gear, vibrator-bars, and vibrator-gears, of the fall-stop bar disposed beneath the outer ends of said vibrator-bars and eccentrically journaled at the ends in bearings on the frame and provided with the outwardly-projecting arm 0", substantially as shown, and for the purpose set forth.

5. In combination with the vibrator-bar provided with a notch in the edge thereof and a gear-locking dog mounted to slide on said vibrator-bar, of the spring 7;, supported in the ears of the dogs and having the downward point or bend that engages said notch in the vibrator-bar, substantially as set forth.

6. The combination, with the retractor-shaft provided with ears 9, the cylinder-gear axle O, and cams 0, arranged thereon, of adjustable retractor-actuating arms 10, fitted onto the retractor-shaftand connected with said ears, substantially as and for the purpose setforth.

7. The combination of the movable engaging plate or edge-piece 11 with the retractor 8 and the gear-holding dogs I, substantially as and for the purpose set forth.

8. In combination with the vibrators, dogs, vibrator-gears, and cylinder-gear in a loom constructed substantially as described, the retractor having the auxiliary part 18 for the shuttle-box-operating mechanism arranged as a sleeve and supported upon the axle of the main retractor, the auxiliary series of cams and actuating-arms connected therewith, whereby said auxiliary part of the retractor is operated independently of the operation of the main part of the retractor, substantially as set forth.

9. The combination, with the driving-pulley clutch V, shipper-rod N and rocker-shaft N, mounted in the breast-frame in a loom, of a crank N, fixed on the end of said rockershaft, the stud n fixed to the frame, knucklejoint arms a and a, connecting said shipperrod with said stud, the link N connecting the center point of said knuckle-joint arms with said rocker-shaft crank, and the actuating-lever n for imparting movement to said rocker-shaft, substantially as shown and described.
