"UNITED STATES PATENT OFFICE HARRY A. DAVIS, OF HOPEDALE, MASSACHUSETTS, ASSIGNOR TO DRAPER'GORPORA- TION, OF HOPEDALE, MASSACHUSETTS, A CORPORATION OF MAINE oLoTH-srLITTING ATTACHMENT FOB Looms Ap'plicationfiled August 26, 1929 Serial No. 388,316.
This invention relates to cloth-splitting attachments which are adapted to be fixed to a loom at a point forward of the fell to split the cloth into a plurality of strips as it advances during the Weaving operation.
This device may be used for various purposes but is chiefly adapted todividing a woven fabric into a plurality of strips during the weaving operation. As many such attachments may be used as is desired depending upon the number of strips into which it is desired to divide the cloth. In a device'of this character it is essentialthat the cutting operation be accomplished in a manner'to prevent all possible distortion-and excessive strain upon the cloth and at the same time produce an accurate andpositive out.
It is the object'of this inventionto provide a splitting device which will function in such a desired manner. l j
A further object of the invention is to provide a device which is automatic and simple in structure and which will function for a long period of time without attention.
A further object of the invention is to provide a cutting device having a rotary disk cutter driven by the motion of the lay.
A further obj ect'of the invention is toprovide a cloth-splitting device, theelements of which are adjustable with relation to the loom and to the plane of the cloth.
The object of the invention is further to provide a device of the character indicated which includes a circular oscillating disk cutter having means actuated from a moving part of the loom to rotatethe cutter in one direction and automatic means to rotate the cutter in the opposite direction.
Other objects and features will more fully appear from the following. description in connection with the accompanying drawings and will be particularly pointed out'in the claims. I
Since the device maybe appliedto'any type of loom the construction of which is familiar to those skilledin the art it is necessary to describe only those elements thereof vhich are directly assoc iated with and which c use the cutter to function.
In the drawings:
i Fig. 1 is a cross section through a portion of a loom showing the splitting device in po sition thereon;
Fig. 2 is a horizontal section on the line 22, Fig. 1 showing the center ate selvage; V p Fig. 3 is an elevation of the device looking from thefront as installed on the loom;
Fig. 4 is a vertical sectional View on the line 4l4, Fig. 1. V
It becomes necessary at times to supply demand for goods which are relatively narrow. The required width may be less than that which can be woven on looms which are available. Furthermore, a saving in cost may be the deciding factor. Since a narrow loom is relatively uneconomical tooperate it becomes desirable to provide other means to or intermediproduce the required narrow width; Since without attention at a minimum of expense.
By the use of a. cloth-splitting attachment such as herein disclosed a loom of medium width may .be employed and the product therefrom be cut into strips of any desired width. The device may be supported from any convenient rigid part of the loom where it will sever the cloth at a point between the fell and take-up rolls. One convenient point of support is the breast beam 1 which is rigidly supported from the loom sides and extends across theloom at a convenient location to receive the splitting devices. A bracket 2is bolted or secured in any desirable way to the breast beam as by the boltB. The bracket Qmay have a slot 4 therein to receive the bolt 3, said slot providing a means to position the free end 5 of the bracket in a horizontal plane. v l
The device itself comprises a frame 6 disposed substantially in a vertical plane and having a horizontal extension 7 adapted to underlie the bracket 2. The extension 7 is adjus'tably secured tothe bracket 2 by means of the bolt 8. Since the cutting must take A lateral slot 9 is provided in the bracket 2 through which the shank of the bolt 8 passes. A lateral groove 10 is provided therein to receive a projection 11 on the extension 7. By loosening the bolt 8 the frame 6 may be shifted laterally and clamped in place by the bolt 8. The frame 6 has adj ustably secured thereto an arm 12 which receives a stud shaft 13 upon which is pivoted a cutter l t. The arm 12'is provided with verticahs'lot 16 to -receive the sha'nk of a bolt- 17 which passes tical movement of the guide 18 upon loosening the bolt. After accurately setting the guide it is held rigid by clamping'tightly with the bolt 21.
The cutter 14 is'circular and preferably made of thin sheet material hardened and ground to a sharp cutting edge at its periphery.
The cutter is mounted on a bushing 28 of any suitable material. As herein shown it is of hard wood having two cylindrical portions of diiferentdiam'eter forming a shoulder 2 l therebetween. The smaller portion 25 is of the same sizeas the central aperture 26 in the cutter. The cutter is slipped over the portion 25 until it engages the shoulder 24. j A metal sleeve 27 is then forced over the portion 25 until it bears against the cutter thus clamping it firmly against the shoulder.
The bushing 23 rotates freely upon the stud shaft 13 which is threaded through the end of the arm 12 and secured by the lock nut28. A coil spring 29 is also mounted on the sleeve to rotate the cutter in opposition to the action of a driving strap 80, the action of which will. be described hereinafter. One end of the spring 29 is inserted in an=aperture 31 in the arm 12. The other end of the spring is passed through an aperture in the cutter and extended into an aperture in the sleeve 27. In this-manner the bushing with its cutter is positively connected to the spring and driven thereby when the latter isundentension.
Any other convenient means may be employed to rotatably mount the cutter on the stud shaft without departing from the invention.
At tlieupper end of the frame 6 a horizontal portion 32 projects rearwardlyand has a cylindrical boss 33 atits end which is drilled cent-rally to receive a plunger 3 1 disposed horizontally and in the-pathof the hand rail 35 of the lay. At the junction of the vertical free fromall unnecessary strain.
portion of the frame 6 and the horizontal portion 32 thereof the frame 6 is divided into two sections 36 having a central space 37 therebetween in which the end of the plunger moves.
The strap-30 is wound'about the metal sleeve 27 for substantially its fullperipheral area and secured at its end thereto by means of a screw 38. The strap 30 which may be of anysuitable fleXibIe-materia1, such as raw hide, extends upwar'dly" and is secured to the forward end of the plunger by means of the screw 39.
A guide .roll 40 is pivoted between the sec- "tions 36 o'f'the frame upon a stud 11. The
roll 40' functions to guide the strap 30 into proper relation with the sleeve 27 as the plunger is actuated by the lay. The spring 29 is adjusted to maintain a slight tension in the strap'30 at all times which tends to..
move the plunger rearwardly so that its'normal position is determined by the stop pin 42'wl1ich bears "against theboss 33.
The'device is sopositioned that the plunger is actuated by theextreme forward motion of the lay and the amount of such movement may be adjusted by means of the adjustment at the'rear end of'theplunger. A screw 43 isthreaded into the endof theplunger and isprovided with a=lock nut 14 which serves a to lock the adjustment when the proper amount of motion has been determined.
Upon each beat up of the lay the plunger is moved forwardly and such motion is transmitted through the strap 30 to rotate the cutter and at the same time wind up the spring 29. Asthelay moves away 'from the plunger the spring29 will actvto rotate the .to maintain the cloth: at the. predetermined cutting point preferably in the normal-plane of the cloth. The cloth is thereby cut accurately, smooth'lyzandat the same time is The cutter may be used in connection with any type of cloth butis especially adapted to splitting goods which :hasbeen specially prepared having acentral orintermediate selvagesuch as that illustrated in Fig. 2. At the point of division there are two relatively dense selvage portions 15 having a central portion 46 inwhich the warps have been'omitted. The
resulting strips of cloth are thereby prorefzs' vided with-finished edges similar to cloth produced. inthe usual manner.
cutting action is positive and certain and independent of the movement of the cloth.
In order to insure protection of the operator from injury a guard is provided for preventing contact with the cutter 14. This guard desirably is in the form of a plate having a cylindrically curved portion 47 which surrounds a portion of the cutter and merges into a vertical shank portion 48 which at its upper end has a laterally extending flange 49 provided with a horizontal slot 50 and which is adjustably secured-upon the arm 12 by the bolt 17 which secures the arm 12 to the frame 6.
