Fig. 6 is a perspective view of the cutting means including the handle with the knife blade detachablymounted therein. 1 y f My present invention as vdisclosed herein is particularly adapted 'for-cutting: off a desired portion o1" length of pliable sheet material, such as oilcloth, rubberized cloth, paper, and the like, from 44a supply of the material, such as the customary roll, bolt, pack, etc.; and vthe illustrated form of invention is particularly'suited for use with 'sheet material which is put up in a roll, and from which the desired portion is extended thru the device to be cut off Vthereby from the roll.

The main and essential part of this invention as disclosed herein consists of the improved combination mechanism 'l of holding and cutting means, whereby the'sheet material is safely held in position and the desired portion is cut 01T therefrom in such a way asto'provide a squarecut end thereon.

In Figs, 1 and 2 of the drawings the essential mechanism 'l of this invention is disclosed as mounted on a rack 8 which includes'spaced standards S connected and reinforced by cross `means ll'and diagonal means Il; while material supporting means I2' is mounted on top thereof, as by means of'bolts i3, to enable convenient attaching and detaching of said supporting means on the standards. This supporting means disclosed includes a trough-shaped kor dished portion l2' for supporting the supply of material I4, which is sho-Wn in the form of a roll.

The formof rack illustrated includes a plurality of arms l5 which extend across the standards and their ends provide curved holding portions !5 disposed at the two sides of the standards; while brace members l5 extend along the form shown herein, and can likewise be mounted on a wall bracket or secured to the wall if desired.

In the form disclosed the means I2 hasv material engaging and guiding means I1 extending from the dished portion I2', which means I1 is adapted to have the desired length or portion I4 of the material extended thereover as it is drawn from the supply I4, as best shown in Figs. 2 and 4. Said means I1 is arranged in the form of curved face means which is engaged by the extended portion I4 of the material during' the cutting operation, and this means includes an upper portion I8 provided with outer edge means I9, along which and in cooperation with which the cutting knife travels, as is best shown in Fig. 3 and is described hereafter; while a face portion extends downward from edge means I9 and a faceportion 2| extends horizontally outward from its lower end. Said portions 29 Vand 2I together form a curved face which is shown as trough-shaped herein; While the outer edge 'of portion 2| provides a ledge 22 which is parallel to edge means I9 and extendsftransversely or squarely across the-path of travel of the portion I4` ofthe material. Y

The desired 'portion of material, when it is first drawn from the roll, then extends over and rests on theedge means I9 and on the ledge 22 of the face means I1. Said ledge 22 then serves for alining or squaring the material as it is extended thereover, whereby to enable producing a' square cut end on said cut-off portion and likewise on the part which remains projecting from the roll.

Means 25 is provided herein which is arranged and shaped to cooperate with face means I1 for holding the material', and it is curved or shaped to t snugly against said face means. In this form shown the means 25 includes a vertical wall portion 26 and a lower horizontal wall portion 21, adapted to t closely against face portions 20 and 2l, when moved into the holding or operative position, so as to hold the material firmly therebetween. A reinforcing bar 28 with a knob or handle 29 thereon is mounted on said wall portions 25 and 21, and this means 25 is movably mounted on the device, being preferably swingably mounted by a pair of side arms 30 extending rearwardly and pivoted by elements 3l on the supporting means I 2.

The movable holding means 25 may be frictionally held vertically in a released position, as indicated in Fig. 2; but I preferably also provide special holding elements 32 which are shown as spring pressed lugs set in the side members 33 of supporting means I2, so that these lugs will hold the arms slightly elevated diagonally, as best shown in Fig. 5, to facilitate drawing the desired portion I 4 from the roll and extending it between the face means I1 and the cooperating holding means 25. These elements 32 are yieldable so that the arms 30 can be pressed down thereover into the lower and operative position, as shown in Fig. 3.

The cutting means 35 provided herein comprises a handle 36 which can be made conveniently from a portion of sheet metal, and it includes two spaced side portions 31 which hold the knife blade 38 therebetween, and for economy and eiciency a safety razor blade is used for the knife, and is secured in the handle by screws 39.

This cutting means is operatively mounted on the holding means, and for that purpose the handle portions 31 are provided with a pair ol.' oppositely extending flanges 4I, and the vertical wall portion 26 of means 25 is provided with a pair of channel means 42 which are spaced to provide a slot 43 therebetween. Said pair of flanges 4I are mounted slidably in the pair of channel means 42, and the knife blade 38 extends thru slot 43, and is adapted to travel longitudinally of the slot and adjacent to edge I9 during the cutting operation, as indicated in Figs. 3 and 4.

With this construction, the movable holding meansk 25 with the cutting means 35 thereon is readily swingable upwards on pivots 3l, and is conveniently held released above elements 32, to facilitate extending the desired portion I4 of the material between the holding means 25 and face means I1; and when this means 25 is then pressed down into its operative position, the knife 38 extends thru slot 43 and is positioned adjacent edge I9, being then readilydrawn thru said slot for cutting off the portion from the supply. The cut-off portion is then still held safely in place by the holding means, and is only released therefrom when the latter is swung upwardly for that purpose. The ledgev 22 at the same time serves as means whereby to aline the extended portion, so as to enable cutting' a, square-cut end on said portion I4 and likewise Von the vextending part remaining on the roll.

The material engaging face means I1 with its edge I9 and the Iali'ning ledge 22,'cmbined with the cooperating holding means 25 and the cutting means 35, provide the essential mechanism 1 of this invention; and that is conveniently con-v nected with suitable supporting means I2 for supporting the supply of material, from which 4the desired portion is extended thru this mechanism and is severed thereby.

This invention is preferably also" provided with additional alining means 45 to cooperate with the ledge 22, and said means is extended at right angles to the ledge 22 and the adjacent edge I9; and in this illustrated form said means is mounted on rack 8, by bracket means 46, and is thereby connected with said ledge, so as to cooperate therewith and facilitate alining the portion I4 relative to the cutting means, in order to assure the provision of a square-cut end on 'said portion and also on the remaining part extending from the roll. This member 45 is preferably also graduated and is in the form of a ruled bar or gauge, whereby to measure accurately the portion or length of material to be cut from the supply; and its upper gauge mark is set at a certain distance from the cutting edge I9, for instance nine inches, so that the desired length of material for said portion can readily be Ineasured accurately and at the same time be alined properly to provide a square-cut end thereon.
