PATENT TAKE-UP MCHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 397,086, dated January 29, 1889.

Application tiled April 30, 1888. Serial No. 272,294. (No model.)

To all nih/m t may con/cern.:

Be it known that I, lVlLLIAM J. LUTTON, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Take-Up Mechanism.

for Looms and I do hereby declare that the following' is a full, clear, and exact description thereot', which, in connection with the drawings making a part of this speeilication, willI enable others skilled in the art to which my invention belongs to make and use the same.

Myinvention relates to looms, and more particularly to a take-up mechanism for looms using a spring-reed. The object of my invention is to provide a mechanism by which, even in very delicate weaving, the speed of the take-np roll can be governed by the texture oi' the goods woven, the variation being regulated by the movement of the spring-reed in beating up, in the manner to be hereinafter :fully described.

Referring` to the drawings, Figure 1 represents a section ot' a loom to which my .improvements are applied, the section being taken just inside one loom side and looking toward the other; and Fig. 2 represents a detail view, looking from the right in Fig. 1.

In the aecompanyii-ig drawings, 1 is a portion ot' the loom-side; 2, the breast-beam; 3, the crank-shaft, and 4 the lay. llolted to the horns 5 ot the lay are stands G, one on each end, to which is pivoted, at 7, the swinging frame S, in which the reed 9 is carried.

On the back side otl the lay-sword 10, at 11, is pivoted a lever, 12, the upper end of which bears against the lower part of the swinging reed-frame 8, being kept in contact with said frame by the iiat spring 13, the upper end of which engages the upper end of the lever 12 and the lower end ot' which is bolted to the lay-sword at 14. As usually constructed the iiat spring 13 bears directly on the swinging reed-frame 3 without the intervention of the lever 12, and this is the case in my construction on the opposite end of the lay. An adjustable hook-bolt, 15, passes through the lay-sword 10 and connes the spring 13, said bolt 15 being held in position to give the required tension on said spring' 13 by means of the nut 16. The lower end of lever 12 has a slot, 17, therein, in which is confined, by means of a Hat shank and nut, the stud 18, through which is threaded the set-screw 19, held in any desired position by the check-nut 20.

On a stud, 21, fast in the loom-side, is pivoted the lower end of a lever, 22, which is provided with a flange, 23, opposite the slot 17 in .lever 12, against which liange the end of 6o set-screw 19 may strike when the lay-sword 10 and the lever are swung into proper position. A spiral spring, 24, acts upon the upper end of the lever 22, one end of said spring' being secured thereto and the other end connected to an eyebolt, 25, which passes through an ear, 26, cast on the loom-side, and is held by a thumb-nut, 27, by means of which the tension of the spring 24 may be regulated. An adjustable hook, 28, passes through the 7o lay-sword 10 and is fastened by a set-screw, 29. ASaid hook 23 is adapted to engage the lever 22 on the opposite side from the setscrew 19.

Fast to the loom-side is a stand, 50, carrying two hubs, 51 and 52, through which slides a rod, 53, provided with a head, 54, on its forward end. The stand 50 is so made that the center of rod 53 comes in line with the cen-v ter of lever Confined by set-screw on the 8o rod 53 is a collar, 55, between which and hub 51 is a coil-spring, 56, on the rod 53. On the rear end of rod 53 is a collar, 57, confined by a setserew. By means of the two collars 55 and 57 the tension of the spring 56, and also 85 the distance which the head 54 projects from the stand 50, may be adjusted.

lTo the upper end of the lever 22 is pivoted an arm, 30, carrying a pawl, 31, on its outer free end, which engages the teeth of the 9o ratchet-wheel 32, mounted on a stud, 33, fast in the take-uproll stand 34.

On the hub of the ratchet-wheel 32 is secured a pinion, 35, which engages an intermediate pinion, 36, also mounted on a stud fast in the takeup-roll stand 34. The pinion 3U meshes with the gear 37, fast on the end of the shaft 33, on which is fastened the take-up roll 39. The take-up roll 39 is of the proper length to receive the width of the goods deroo sired to be woven, and the shaft 33, upon which said roll 39 is mounted, projects from each end thereof, and is supported in two stands, 34, secured to the loom-side, the gearing l'or operating the take-np roll being pl aeed outside the stands fil.

'Upon the upper ends of stands Si are hubs -L0, into which are screwed rods 4.1,whiehprojeetimt under the lay -land are l'astened in any desired position by a cheek-nut, ft2. The length of the rods ll is sueh, and they are so plaeed, that when the lay beats up the projecting points engage the springs .l ."l and push them ont of eontaet with lever ,l2 and reedtrame S adistanee determined by the adjustment ol. rod -Ll Ain its supporting-hub il) on stamfl Sl-l. 'lhe lever has a bend or eu'rve in it at a point, 455,110 allow the rod -l-l to pass by it and engage the spring i3.

'.lhe dotted lines -l-l represent the lines ol' warp with the shed o} m,and represents the eloth passing over the breast beam 2 around the take-up roll 235i, and to the elothwinding roll ld, whieh is driven in the usual manner by gearing :trom the take-up roll, the gears being plaeed on the opposite end. ot the talCe-i'lp-roll shafts .trom the train ot gearing 255, 23H, and 37.

From the above description, in eonneetion with the drawings, the operation ot' my im,- proved take-up meehanism will. be readily understood by those skilled in the art, and isas .t' ol lows 'lhe several parts being in the position shown in the drawings, the shuttle is thrown, laying a shot ot lilling in the shed, and the lay beats up. '\\'hen the lay gets nearly up, and bet'ore the .filling begins to meet appreeiable resistance in going into the eloth7 the projeeting ends ot' the rods ll engage the springs l Il and lrelieve the reed-trame S and the lever 12 ot their pressure.

The adjustable hook 2S, which determines the position Vin which the lever 22 is leltr by the lay, and the set-screw lf) are so plaeed that about the time the rods ll engage the springs l2) the point ol' the set-screw lt) engages the liange 23 on lever 22, bringing the tension ol the spiral spring Q-l to bear on the reed-tranne 8 through lever l2. lhe spring 2l is adjusted by thumb-nut 27 tothe desired tension, regulating the amount which the reed-frame sprin lbaek in beating the illing into the eloth to the desired texture. The more the reed springs back the farther the point ot' set-screw 19 throws the lever 22 torward, and the more teeth are taken by pawl l on the ratchet-wheel. 32. lVhen. the lay goes back, the lever .is pushed or drawn by hook :28 over to the same point everytime, turning the take-np roll iid, through the train ot' gearing E55, Sie, and $37, an amount proportioned to the sjfiring of the reed. 'lhe throw ot' the pawl 23]. may be further regulated by the position ot the set-serew l?) in the slot i7 in the lever l2, the moving ot' it down inereasing the throw of the pawl .tor the same movement ot' the reed.

It will be observed that the pressure ol' springs 13 is taken oli the reed. by the rods 441 justy as the pressure of springl 2st is applied. .lhe reason :t'or this is, that a pressure ot. the reei'l-.t'rame which lis sulieient to hold the reed up rigid for the passage ot' the shuttle while the lay is passing the baek eenter is not delicate enough on some goodsto weigh the resistanee of the Ylilling going into the eloth.

A tritling tremor ol theretal while the shuttle is passing is sutiieient to eause it to miss goin squarely into thebox'.

The purpose of the spring-rod 53 isto serve as a stop [for the lever to prevent .its being drawn by spring il, or otherwise, beyond the point towhieh it.- Vis earried by hook. 2S, the rod 523 being adjusted so that its head 54: engages lever 22 just as hooi; 2S eea-ses to push lever 22 baelC. The spring 5U is ot su iteien t strength to prevent moving ol lever 22 by spring 24 imlependent ot the aetiou ot' t-he hook 2S. The parts are usually so adjusted. that spring 5V does not aet, `i t merely preventing breakage in ease ot imperteet adjustment.

Usually the tension of the goods being woven over the take-up rolls is sut'tieient to hold lever 22 at the point to whieh it is pushed. by hook 2S, and the spring-rod 53 might be dispensed with, except in very light work.

It will. be understood that the details of'eonstrueti on ot the several parts ot' my improved take-up mechanism. may be varied somewhat troni what is shown and deseribed, it desired, without depz'irting from the principle ot' my invention.

Ilavingthns deseribed my invention, what I elaim as new, and desire to seenre by lietters Patent, is-
