SPECIFICATION forming part of Letters Patent No. 609,156, dated August 16, 1898.

Application filed January 15, 1898.

To all whom it may concern:

Be it known that 1, JOHN T. MEATS, of Taunton, county of Bristol, State of Massachusetts, have invented an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention relates more particularly to that part of the loom mechanism called the take-up, whereby the cloth is taken up as by the operative without stopping the loom.

By the application to the loom of my present invention, to be hereinafter described, the weaver cannot speed the take-up abnormally without at once stopping the loom, the take-up mechanism being so connected with stopping means for the loom that the former cannot be thrown out of gear without effect ing the operation of the latter.

I have also devised novel devices whereby the cloth is wound by contact with and un-' derneath the take-up roll, the operativebcing enabled to remove the cloth-roll at any point of its downward movement as it is wound without the exertion required to unduly compress a spring or springs, as has been common heretofore.

Various other novel features of my inven tion will be hereinafter described in the speci fication and particularly pointed out in the claims.

Figure 1 is a partial left-hand side eleva tion of a loomwith my invention embodied therein. Fig. 2 is a partial front elevation thereof. Fig. 3 is a plan viewof some of the devices shown in Figs. 1 and 2,110 be described. Figs. A and 5 are enlarged views, in side and Serial No. 666,743. N m del-l front elevation, of the let-back pawl, of novel construction. Figs. 6 and 7 are enlarged .views, partially in section and in side eleva tion, respectively, of the clutch forming a part of the connections between the take-up and stopping means. Figs. 8 and 9 are front and side views, enlarged, of a portion of the controlling means for the loom-brake. Figs. 10

and 11 are side and front views of modified devices at the loom side for yieldingly sup porting the cloth-roll. Fig. 12 is an enlarged front view of a portion of the lay to show a novel device for regulating the pressure ex erted upon the shuttle by the shuttle-binder; and Fig. 13 is a transverse sectional view thereof on the line at m, Fig. 12, looking to the left.

The loom-frame A, breast-beam A the main driving-shaft A, having fast and loose pulleys A A thereon, and a brake-disk A may be and are substantially all of well-known or usual construction, the take-np mechanism being actuated in usual manner from either the cam or the crank-shaft of the loom, and herein I have shown a bevel-gear a on the cam-shaft A in mesh with a similar gear a, fast on an intermediate shaft a suitably supported and provided at its outer end with a worm a but shown in Fig. 1.

p The worm is in mesh with and positively drives the wormgeara", rotatably mounted on a shaft a (see Fig. 6,)supported in suitable bearings on the loom side, said shaft having fast thereon at its inner end a pinion a, which drives the gearing between it and the gear I)", fast on the shaft of the take-up roll B. H

As shown in Fig. 6, collars 2 3 prevent the worm-gear of from moving longitudinally on the shaft a said gear having on its inner face a clutch member a (shown as toothed or serrated in Fig. 6) to at times cooperate with a similar clutch member a, secured to or form ing a part of the holding or detent wheel a", longitudinally movable on the take-up-actuating shaft (1 and keyed thereto, asat a to rotate with it. r

The hub a of the detent-wheelfla? has an annular groove thereinto be entered by lugs 4. of a yoke like foot on a vertical rockshaft a, Figs. 1, 2, 6, and '7, mounted in an upright bearing 1%, shown in Figs. 1 and 2 as depending from the holding-plate N, provided with the usual holding-notch n for the shipper-lever S A knock-off lever b, pivoted at b on the holding-plate N, (see Figs. 1, 2, and 3,) operates in usual manner to throw the shipper out of the holding-notch upon failure of the filling, the inner end of the lever engaging the usual weft-fork plate. (Not shown.) When the filling fails, the knock-off lever is actuated in usual manner, swinging to the right, Fig. 3, releasing the shipper, which is thrown by its controlling-spring S, actuating the beltshipper (not shown) to ship the belt and stop the loom.

The upper end of the rock-shaft a has fast thereon a laterallyextended arm a, connected by a link a with the knock-off lever 19, the link having downturned projections 5 5 to embrace the arm, while at its other end said link is permanently secured to a seat b on the knock-0ft lever by a suitable bolt 6.

It will be obvious from the foregoing that if the take-up-actuating shaft a be speeded up by the operative manually to improperly increase the length of the cloth being woven the clutch member a. will be moved to the right, Fig. 6, rocking the shaft (L14 to swing the arm at forward, such movement of the latter acting at once through the knock-off lever b to effect the stoppage of the loom. It will also be obvious that when the knock-off lever is actuated by failure of the filling the clutch mechanism will be operated to release the take-up roll from continued operation, and in connection with the take-up I may use an adjustable let-back pawl, (shown separately in Figs. 4 and 5,) which operates to let back the take-up roll a predetermined amount whenever the detent-wheel a is unclutched fromthe actuating-gear a The pawl c is longitudinally slotted at its upper end at o to receive loosely a pin at, carried by ears nibetween which the pawl slides, said ears being erected on the depending bearing 47%. An adjusting-screw c is extended through a threaded boss 0 on the end of the pawl and into the slot c',and the amount which the pawl will let back is regulated by the position of the inner end of the said screw, it being evident that the pawl will hang down by its weight as far as permitted by the screw, which then bears on the pin a. The greater the play permitted the pawl between the end of the screw and the adjacent end of the slot the greater the amount let back. To prevent the pawl from leaving the detent-wheel a when the latter is moved sidewise to throw it out of gear, I have provided the pawl'with flanges 0 which extend over each side of said detent-wheel, while permitting the lateral movement of the latter.

The brake-sheave A is adapted to be engaged by a brake-shoe d, Fig. 1, upon release ofithe shipper, said brake-shoe being mounted on a bent lever D,..fulcrun1ed on the loom side at d near the periphery of the sheave, the long arm of the lever D extending to the front of the loom and having mounted upon it an actuating-weight W, as herein shown. A releasing-rod d is attached to the lever D, and at its upper end said rod has a catch 61 Fig. 9, the lip 61 of which normally engages the upper edge of an opening a in the holding-plate N, the shank of the catch passing up through said opening.

The knock-off lever 12 has an ear b thereon, straddled by the bifurcated end of a dog d pivoted on the ear by a pin d the hook-like end of the dog engaging the preferably beveled end of the lip of the catch (1 as clearly shown in Fig. 9, when the loom is running. While the catch engages its support the lever D is held lifted, maintaining the shoe 01 away from the sheave A but when the weft fails the releasing movement of the knock-off lever 1) acts through the dog (1 to disengage the lip of the catch from the plate, releasing the catch and permitting the weight to rock the lever D and apply the brake.

The journals of the take-up roll B are mounted in upright standards B, one of which is shown in Fig. 2, within the loom sides, secured to the breast-beam A and to brackets B said standards being longitudinally slotted at B to form guides for sliding supports 13 for the journals of the cloth-roll B Each support is shown as a plate extended through the slot B and provided at its front end with a projecting handle b the rear end having an enlargement or weight b at the back of the standard, while a lateral ear 6 is formed on the support at the base of the handle. Pins or lugs 8 and 9 extend oppositely from each side of the support and bear upon the front and back faces of the standard, the pins being so placed that when the front end of the support is lifted it is cramped or clamped, as it were, on the standard.

A strong spring S below the breast-beam has attached to the end thereof a cable or other flexible member 12 which passes over a guide I) on the standard B, at its upper end, and thence to the lug b on the cloth-roll support B to which it is suitably attached. The spring holds the cloth-roll up under the takeup roll 13, and as the roll of cloth increases in diameter it pushes the supports down along the standards, the increasing weight of the cloth being provided for by the increasing tension of the spring. The spring acts to lock the supports on the standards at any point until the tension of the spring is overcome either by sufficient weight or pressure brought upon the cloth-roll or upon the handles b of the supports.

Whenever it is desired to remove the clothroll at any point of its travel, a slight pressure upon the handles 19 overcomes the spring tension, releasing the supports, so that the supports can be moved downward as far as which act upon the shuttle-binder B desired. The pressure upon the handles being removed, the tension of the spring at once acts to again lock the supports B at the desired point, so that the removal of the cloth roll is permitted at any desired place in its travel along the standards. This capability of removal at any point is a novel feature, so far as I am aware, and a very valuable feature of my invention.

In Figs. 10 and 11 I have shown a modified form of support for the cloth-roll, the modification, however, consisting in the manner of applying the spring to the sliding automatic locking-supports B, the latter being of the form and character hereinbe-fore described and operating in the same way on the slotted upright standards B, and it may be noted in this connection that the slot at the lower end of each standard is enlarged, as shown in Figs. 2 and 11, to permit the withdrawal from or the insertion of the support into the slot.

In the construction shown in Figs. 10 and 11 the lateral lug or ear 6 is omitted, and instead the support has on its inner side an ear I)", cut out or recessed, as at 6 (see dotted lines,) to receive the reduced and convexed tip f of a tube f, which slides telescopically in a tubular guide f, suitably secured to the standard B,the tubes f and f containing a spring S one end of which bears against the upper end of the tube f, the lower end of the spring resting on the bottom of the tube or guide f. As the weight of the cloth on the roll B increases the supports B will descend, as hereinbefore described, and the tube f will telescope into its guide f gradually compressing the spring S Bydepressin g the handles 2) of the supports, as before described, the support is unlocked and can be readily pushed down far enough to permit the supports to again automatically lock at any point on the standard, so that the roll of cloth may be removed when desired.

The salient feature in the cloth-roll-s upporting mechanism in either construction shown is the capability of the removal of the roll at any point of its travel and the automatic looking of the roll supports on their upright guides.

In Figs. 12 and 13 I have shown a convenient device for regulating the tension of the shuttle-binder spring, the lay A being shown as provided with the usual rock shaft h, mounted in bearings 72. depending from the lay, said rock-shaft carrying the usual binderfinger h, only one of which is herein shown, The rock-shaft It carries the dagger 71 for the antismash or protective mechanism,of usual form, and the hub 71 of the shuttle-binder finger h is held securely in adjusted position on the rockshaft by means of a suitable set-screw 71. The hub it is toothed or serrated at one end, as at 771 (see Fig. 12,) to engage the correspondingly-toothed end m of a nut m, rotatably mounted on the rock-shaft, and to which one end of the'controlling-spring S is 'at-' tached, the other end of the spring being attached to one of the brackets h as herein shown. In order to vary the tension of the spring and thereby the pressure of the binder upon the shuttle, it is only necessary to rotate the nut m in one direction or the other to tighten or loosen the spring. This is a very convenient and ready means for varying the tension.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is l 1. In a loom, take-up mechanism, means to positively actuate it, stopping means for the loom, and connections between said stopping means andthe take-up mechanism, operative when the latter is moved in advance of its actuating means, to stop the loom.
