PATENT. OFFICE PHIILIP 13-. ROHN'ER,

OF CARROLL, IOWA RAG Merlin A pneatien filed March 14,1929. Serial no. 346,997.

This inventionrelates to a device for ripping rags into strips such as might be used in the'weavin of carpets, rugs and the like, o'rfor any desirable purpose. 1

Ragsas collected will be ofvarious shapes and sizes,"and beforethey canbe used, for most purposes it is desirable to form them into" uniform strips of a predetermined width and accordingly anobject of this in- 10 vention is the provision of means to quickly and easily cutor rip one rag after another into strips of the same width, regardless of the direction of the weave or grain of the cloth;

' Varying uses and conditions may necessitate" a variation inthe width ofthe'strips andanother object of this inventionis the provision of meansto easily measure the width of strip desired and cut the cloth to "20 this measurement.

It is also an object of this invention to provide a measuringgage which functions in useas agnide for the strip as it is being cut,which' gage is adjustable instantly.

A further object is the provision of a structure in whicha'razor blade may be utilized as the ripping or cutting medium, andthe device isso designed as to accommedate any make', shapeor form of safety razorbladeasa'outting tool, by making a very" slight adjustment, l I

" The devicealso may readily be usedas a seam or thread ripper, or for many other e purposes, either with or Without the guide. "as To the: attainment of these-and other objects there are provided certain arrangements and combinations of parts hereinafter described and more particularly pointed out in the appended claims; Refereneeis to be 4'0 had toth'e accompanying drawings, which: Figure 1 is a diagrammatic View of the invention, i perspective, showing the manmen of its use,

E "ar is al' l f s' f i r e y milev us'tiatiiigashghtly'modifiedform arm-verifies. e I

It will be observed that a frame or body 5 is provided with a shoulder 6 on its lower side for'pos'itioning the body on any suitable support as a table or bench to which it may be clamped by a clamp 7.

The top of the body may be skived or flattened as at 8 to form a thinner portion suitable for en agement by the clamp.

A suitable guide such as a groove 9 or other tracking means is provided along atleast one sideof the body, with which is engageable a flange 10 of a slidable member 11. This memher is adapted to form a guide for the rags as they are ripped, andto this end is provided with an upstanding abutment or gage element 12 against which the rag edge is placed asindicated in Figure 1.

Finger pieces 13 are illustrated at one end of the slidable member and form a means of manipulating the member when setting the gage for different widths of strips. The member 11 may be held in position by any desira-ble means, as friction, but if made of spring metal, will retain its position by inherent tension of the flange 10, positioned in groove 9. If desired, a set screw might be used to hold the member in position.

The body 5 may be provided with a section 1 1, separable therefrom and which is held in place to complete the body by a bolt or screw '15 passing through the section into the body.

lVith this construction it will be obvious that ifa razor blade 16 is positioned between the section 1 1 and the adjacent portion of the body 5, the blade can be clamped in position 'by forcing the screw home.

Another way of mounting the blade is shown in Figure 4, in which the body 5 is slotted as at 17. The blade is' dropped into the slot and clamped by a screw 18.

Regardless of mounting, however, the blade will have one end projecting above the body 5 and member 11, the latter being cut away as at 19, for the purpose, The edge of member 11 along the cut out may be graduated if desired. 7 a

In the use of the device, the body 5 is damp d o e 'bl Q1 'u'pr r th m b 1113 pe'sitiened to locate thegage-m for adearea width an rag- -26 is" placedagainst the gage, and drawn past the cutting edge of the blade. It will be seen that'a rag can thus be ripped with straight edges, no matter in what direction the weave or grain runs, and that any predetermined width of strip may be obtained, with an assurance of uniformity in successive strips. 7

WVhenablade loses its utility, it is but a simple matter to substitute another blade in its stead, and anytype of blade may be used.

The device is also handy as a means of ripping seams, cutting threads, etc., it' being unnecessary in some instances to use the gage and guide member. This invention is capable of a variatyof uses and modifications and it is not intended that same shall be limited except as hereinafter claimed;

Having thus described my invention, what I claim as-Inew and desire to secure-by Letters Patent of theUnited States is 1; In a devicefor ripping rags, the combin-ation of a body member and a cutting member, said body member having a detachable portion effective to engage said cutting memberand clamp same in the body member, and a guide movable on said body member relative to said cutting member, effective to guide a rag strip as it is ripped, said guide having a rounded surface adapted to project under the strip to facilitate movement of the strip, and gauging means on said projection.

means to fasten said body to a support, a

cutter, means to attach said cutter to said body, a carriage slidable along said body and having a portion adapted to project under a rag to be ripped,-acalibrated gauge arranged onsaid portion, said portion having a slightly rounded surface and means to move said gage relative totsaid cutter, whereby arag drawn over said body will be ripped by said cutter to a predeterminedwidth and will be guided by said gage, to produce astraight edge. Q4. In a device of the character described, a body member including a cutter, a' carriage movable on said body member to-ward and from said cutter having a portion extending transversely of said cutter, means on' said carriage effective to guide a strip of material passedover said body membengauge' means on said portion, cooperativefwithsaid cutting meniber to indicate location ofsaid guiding means, said carriage, guide means and gauge means being arranged as a unit.
