` To 'cI/,ZZ whom it may concern:

Be it known that I, ARTHUR M. HAMILTON, a Citizen of the United States, residing at Fall iver, in the County of Bristol and State of '5 Massachusetts,have invented certain new and useful Improvements in Looms for Weaving Bordered Fabrics; and I dohereby declare the following to be afull, clear, and exact description of the invention, such as will enable othxo ers skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful mechanism applied to looms for weaving cords in fabrics for making check goods I or handkerchiefs with corded borders. Such goods have heretofore been woven on a loom having a dobbyjhead, the ordinarypattern`` chain', and other attachments, which make the mechanism expensive as to first cost and also zo comparatively expensive in Operation.

The object of my invention is to do away 'with the dobby-head and provide mechanism at a greatly-reduced cost which will effect- Y ively operate to Weave a corded border in a handkerchief or "cords throughout the Whole fabric to make check goods; also, to enable the operator Or attendant to Weave a given number of yards of fabric lWith less expenditure of time and labor than Would be required 3o in the use of the (lobby-head. g

My invention comprises certain improved devices and mechanism for controlling the shedding of the Warp-threads and also for regulating the take-up motion, the shedding mechanism and take-up motion being synchronouslyoperated, stopped, or started for producing the desired corded border or corded effect throughout the fabric in the manufacture of check goods. 4o The matter constituting my invention will be detined in the claims.

I will now describe thedetails of construction and arrangement of the best embodi- Vment of my mechanism by reference to the accompanying drawings,'in Which- Figure 1 represents av front elevation of I part off'a loom' containing my devices. Fig. 2 represents an end elevation thereof. Fig.

l 3 represents a transverse sectional elevation -shown in Fig. 1.

showing part of the take-up mechanismnotgo Fig. 4 represents a sectional detail'view, on enlarged scale, of the mechanism of the take-up motion. Figs. 5an`d 6 rep-V resent elevations of certain devices at the lefthand end of the loom. Figs. 'Zand 8 show cer- 55 tain detail Views of parts shown in Figs. 5 and 6. Fig. 9 representsa transverse section through part of the disk-gear shown in Figs. 5 and '6. Figs. 10 to 17, inclusive, represent detached detail views of the pattern-chain 6o mechanism. Figs. 18, 19, and 2O represent detail views of the cams on the cam-shaft and operating mechanism therefor.

The mechanism Of the take-up motion at the right-handlend of-the loom is shown in Figs. 3 and 4 and is operated in the usual lnanner from the crank-shaft GO, which is 1 connected by link 61 to the lay-sword 63,- which supports the lay 62. 1 I

The take-up pawl 2 is hingedl toa bracket 7o 1, which is bolted to the lower end of the'V laysword and engages at its outer hooked end with the ratchet-wheel, which, together With a spur-gear or piniona, is mounted on the stud-shaft 3b, secured to the loom-frame A. 75 The pinion 3a meshes With the spur-Wheel A, mounted on shaft 5 of the cloth-roll, which is journaled in the usual mannerin the frame A. A pawl 6, pivoted to a pin or stud Ga, se-

'cured to the frame, engages with theteeth 8o On the ratchet-Wheel 3 to preventit from running backward.

The paWl 2 is ordinarily held in engagement with the teeth of wheel 3 by means of spiral spring 8, attached at one end to thel pawl and at the other end to the frame Ai When it is desired to put more than one pick into the fabric, as when a cord is made, the gearing of the take-up motion is stopped by means of strap 7, attached to pawl 2 and 9o passing down under pulleys 7 and thence up to the lifting-lever 36 in the pattern-chain mechanism. At the proper moment lever 36 is lifted by one of the balls in the patternchain, thus pulling on strap 7 and holding 95 pawl 2 away from the teeth in Wheel 3.

I will now describe the devices at the lefthand end of the machine for bringing into and the harnesses lat rest the required number of picks may be put in to form a cord, as

determined by the position of the balls iu the pattern-chain.

lIO

At the left-hand'end ofthe loom there is secured to the'end of shaft 5 a toothed gear i 9,'which meshes withthe disk gear 10, Figs. v5 and 6, supported on a stud-shaft 10', projecting from the frame A, as shown in Fig. 1. The disk gear 10 is provided at the outer side near the periphery with a circular dovetail vprojection as shown inFig. 9, and such projection is provided with an interior notch 10b, as shown in Figs. 5'and 6. zo

The dogs 11, having transverse dovetail grooves 11a, are

inserted at the notch 10b ontol the dovetail projection 10, and may be adjusted thereon in any desired position and held in place by the screws 12, bearing upon the face of the projection'lOa, as shown lin Fig. 7. By means i of the dovetail joint, made as above described,

the dogs may be readily adjusted in any desired position on disk gear 10 and serve to l regulate the length of the pattern in the fab SOP ric. Below-the disk gear 10, Figs. 2, 5, and 6, the bent lever 13 is pivotally connected by pin 1 3Ytoalug or bracket 13C on the frame,

and to' its opposite end is attached. a spiral spring 14, Fig. 2, which is also attached to the frame for supporting the lever in the desired position. Lever 13 is also provided with an-upwardly-projecting'horn 13", which in practice is engaged by the `dog 11 for depressing the lever, as in Fig. 5. When one of the dogs 11 passes olf from horn 13b, the lejver is again raised by spring 14. A wire 15 connects at itslower end with lever 13 and extends upl to the pattern mechanism, where it connects with pawl 29, Figs. 11, 12, 13, and 15, for lowering said pawl to engage with the teeth of ratchet-wheel 31 when the lever 13 is lowered or raising said` pawl to disengage it from the teeth of said wheel when the vlever 13 is raised. Near the outer end of 'awl 29 is connected an eye 30, Fig. 12, through which passes wire l5. The pawl is thus caused to engage with and slide on the wire when it is raised and lowered, as illustrated in Figs. 13 and 15.

I will now describe the mechanism for driving the pattern-chain, and thereby operating certain lifting- levers 36 and 3 7, by means of which the take-up motion' may be thrown out of gear and also the cams which operate the harnesses may lat! the same time be thrown out of gear, so that the take-up motion and the shedding operations may be temporarily stopped while the desired number of picks areput in to form a cord in the fabric.

Referring now to Figs. 1 and 2 and the detailviews, Figs.`10 to 17, inclusive,tl1e ratchetwheel 3 1 isprovided with a long barrel or sleeve-shaft 31a, which is mounted upon a around which passes strap or ring 23, havingv connected with it the connecting or drivmg rod 23a, which at its upper end 'connects by To the left-hand end of a pin 2S with the slotted arm 27 The pawl 29 is also pivotally connected by said pin 28, so that its free end may engage the teeth of ratchet-wheel 31. Motion imparted to the driving-rod 23a by the eccentriccaus'es the arm 27 to move in the arc of a circ'learound ratchet-wheel 31 and when the 'pawl 29 is in engagement with the teeth thereof to partially revolve' said 'wheel at every upward stroke of rod 23a. Since the notched patternwheels 32 are secured to the sleeve-shaft 31,

they are turned with the 'ratchet-wheel and Y carry forward pattern-chain 33 with its balls 34. The lifting- levers 36 and 37 are pivotally connected at' their rear ends to a studshaft 35, projecting from a bracket on the frame, and rest in an inclined position upen the chain above the pattern-wheels 32, as clearly shown in Figs. 16- and 17. A bent lever 26, Fig. 10, is also'connected to shaft 35 andis provided .at its inner end with a roller 26a, adapted to bearin the notches of the check-wheel 25, and is connected at its outer end by means of a spiral spring 50 to an arm 51, secured to the frame. Thespring 50 presses the roller 26 into a notch of Wheel 25, so as to hold the Wheels which 'are attached to* the sleeve-shafts 31 from revolving, except when the ratchet-wheel is `caused torevolve by engagementof pawl 29. An adjustingwheel 64, Fig. 1, similar in shape to the check- Wheel, is also secured to the sleeve-shaft 31" and. is used to turn-the pattern mechanism by hand when adjusting it.

Tothe inner end of lever 37 is con'neeted a wire 21, which connects at its lower end with the bell-crank 20 on pin 20, which connects at its other end by means of rod'53 with the clutch-lever 54 for operating the clutch on the cam-shaft, as shown in the detail views, Figs. 18 and 19. i

The cams 41 are loosely mounted on the cam-shaft 38 and are held in position by the collars 42 and 43, and said cams are suitably notched for engagement with the clutch 40 and the catch 56a. The clutch 40 is connected with the cam-shaft by means of a feather or spline 39. The clutch-lever54 and the catchlever 56 are pivotally connected ata and b to the feet or licor brackets 46 and 47, and said ylevers are pivotally connected one to the IIO other 5." spiral spring 57 connects with the catch-lever 56 and also with the iioor o'rbase plate oftheloom for pullingl catch 56a"-of said 'lever tout of engagement with the camand at'thef'same time moving the clutch-lever54 and the clutch 40 into engagement withthecanifasfshown in Fig. 18.

As heretofore rexpla`i`ried,"ithe strap 7, which connects with the take-up`pawl 2 and passes the fabric to form the desired cord.

The operation of 'myldevices is very simple and practically automatic, so that no extra labor or time is required of `the attendant for operating the loom to Weave a bordered fabric. Before commencingthe weaving operations the balls Will be properly placed in corded border.

the pattern-chain to produce the desired in the desired position tothe disk gear 10 to act at the intervals of time for bringing the pattern chain and mechanisminto operation to produce the desired :corded border. The number of dogs 11 and their relative positions on the disk gear 10 may be varied according to the variety or style of corded border desired. When one of the dogs 11 passes into contact with the horn 13b,fthe lever 13 vvill be depressed, thereby pulling down the Wire or rod 15 and engaging paWl 29 with the teeth of the ratchet-Wheel 3l. The eccentric 22 being in continuous operation and its driving-rod 23 in connection with the arm 27, the ratchet-Wheel 31 Will now be revolved, causing simultaneous revolution of the notched pattern-Wheels 32 and continuous movement of the pattern-chain 33. When the balls 311 of the pattern-chain pass over the Wheels, they will raise the levers 36 and 37, causing the strap 7 to pull down the take-up pawl 2 and the Wire 21 to disengage clutch L10 fromthe cams 4l, thus stopping the mechanism of the take-up motion and the harnesses While the desired number of picks are put into the fabric to make the desired cord. When the dog 11 passes off from horn 13", lever 13 will again be pulled up by its spring 14, thereby raising the rod or Wire 15 and lifting pawl 29 out of engagement With the ratchet-Wheel 31, as shown in Fig. 15, thus stopping the motion of the pattern mechanism. So soon as the balls 34 pass of from the pattern-Wheels 32, levers 36 and 37 Will drop onto the chain, as shown in Fig. 16, and the straps 7 will be released, permitting take-up pawl 2 to be again pulled by spring 8 into engagement with ceases 1. ,Y

The dogs 1l are also secured- Y thefratIchet-wheel 3, and Wire 21 will belowered, permitting the clutch 40 to be pulled by spring 57' into engagement With the cams, so thatplain Weaving of the fabric is again resumed? When clutch 10 is pulled out of engagement with the . cams 4,1, as above described, thev` catch 56@ is at the same time pulled intoelngagenlent with the cams for preventing them from turning outiof their proper position'- In order to prevent the driving mechanism which runs the pattern-chain from stopping on a ball, thus holding the shed open when not desired,l provide a safety device, consisting ofa safety-motion Wheel 17, Figs. 5, 6, 7, and 8, mounted on pin 19, held by bracket 18 and connecting by a strap 16 with lever 37.

The Wheel 17 is provided at its periphery with -a horn 17 a, adapted to bear upon lever 13, as shown in Figs. 7 and 8. A ball of the pattern-chain being on wheel 32 it holds lever 37 in the raised position, and thereby the strap 16, attached to said lever,will pull upon Wheel 17, causing :its horn 17 to bear upon lever 13 and. hold it down, as shown in Fig. 8, until the said ball has passed off from Wheel 32. Evidently this safety mechanism will thus act to keep the pattern-wheels in motion till the balls have passed off from them, even though the dog ll-has passed off from horn 13b of lever 13. e

Motion may be taken from the cam-shaft instead of the crank-shaft to drive the pattern mechanism, but in this case the control is limited to two picks to each revolution.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1sm` l 1.
