CUTTING AND MEASURING APPARATUS FOR OHACLOTH 01R. SIMILAR MATERIAL 13 Glaims.

This invention relates to a device for handling material such as oilcloth which is usually carried in rolls. Such material in stores is often carried in a cabinet having compartments for the various rolls. It has heretofore been difficult to dispense the material from the rolls to measure it and to sever the desired piece so that the severing out extends perpendicular to the longitudinal edges thereof.

It is an object of this invention to provide a simple and efficient means by the use of which the cloth may be drawn from the roll, measured, held in cutting position and accurately cut across the width thereof.

It is another object of the invention to provide a simple and efii-cient means comprising a member over which the cloth may be positioned and resilient means for engaging the cloth at opposite sides of said member and holding it taut over the top of said member together with a cutter movable longitudinally of said member to cut the cloth through the taut portion thereof.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to similar parts throughout the several views and in which:

Referring to the drawings, a cabinet I5 is shown having a rear wall or side 15a end walls i512 and a top I50. Shelves I512 extend between the end portions 15b, the same inclining down; wardly toward rear wall 15a and having short vertical flanges I5e at their front and rear ends. Said partitions ltd form series of compartments 15f in cabinet IS. A member 16 illustrated as an angle iron extends along one end of cabinet 15 being secured by spaced headed screws ll. Sail member I 6 forms the support for a pair of brackets 18 of angular form which are secured thereto by the headed and nutted screws 19. Brackets it have vertically extending spaced parallel portions between which is pivoted one end of a bar 20. While this bar might be of various forms, in the embodiment of the invention illustrated it is shown as formed of a tube and the end disposed between brackets I8 is pivoted thereto by a headed and nutted bolt 2|. A measuring wheel 22 has a spindle received in one end of member 20 and held therein by a set screw 23. Measuring wheel 22 has a knurled central portion 221a and side portions 221) and 220 of smaller diameter than portion 22a, said latter portions being graduated to register in inches and feet respectively. Pointers 24 and 25 are positioned to cooperate with the graduations on portion 220 and 22b respectively. A headed and nutted bolt 26 extends between brackets 18 adjacent the top thereof, the same forming a rest for member 20 when the measuring roll 22 is in inoperative position as shown in dotted lines in Fig. 1. Member 16 is continued for-. wardly of the brackets l8 and the same has secured at its inner side by headed and nutted bolts 214 an upstanding bracket 21. Bracket 21 is of plate-like form and has at its top an open-ended slot 21b. Said bracket has a horizontal latch 21c thereon on which is mounted a plate 21d projecting forwardly and having a semi-cylindrical end 216 with its concave side disposed upwardly. Another plate 21f is slidably connected to and overlies plate 21d and has a curved forward portion adapted to cooperate with portion 216 in receiving and holding in position a shaft 279 which also rests in the slot 21b of bracket 21. A crank handle 21h is secured to the outer end of shaft 219'. Shaft 21g has secured thereto segmental and substantially half-cylindrical members 211', the same having their flat sides adjacent and separated by a narrow slot 217'. The members 212' thus form a slotted roll and this roll or roller eX- tends from bracket 21 parallel to the front of cabinet I 5 to another bracket llm also supporting plates 21d and 21 similar to those already described. Plates 21d and 21f are connected by sliding movement of plate 21 for headed screws 21k.

With the described construction the plates 21f may be moved rearwardly and the front curved portions thereof will move from over shaft 219. Said shaft with the roller formed by portions 212' together with crank 21% may be lifted. from bracket 21. When said parts are replaced shaft 21g will rest in brackets 21 and in portions 216' and plates 21f may be moved forwardly so that their forward curved portions move over shaft 21 somewhat resiliently.

In Fig. 14 a cylindrical core 33 is shown preferably made from cardboard. Core 33 has a cylindrical opening therethrough into which may be inserted the member 3A having oppositely disposed curved resilient arms connected at one end by a central portion which is secured by bolt or -rivet Ma to a shaft 34b carrying a circular flange 340-. A crank 36d is secured at one end of'shaft 34b in any suitable manner as by pin 34c. Another member 35 similar to member 34 is secured at its central portion to a shaft 35a also having a circular flange 3%. As shown in Fig. 14 when members 34- and 35 are inserted in the core 33 flanges 34c and 35b engage the ends of said core respectively.

A member 28 is secured to the opposite end of cabinet IS, the same being illustrated as formed of an angle bar having a horizontal flange at its front portion which projects beyond cabinet I 5. Said flangeforms a support for a pair of oppositely disposed brackets 23 of right angular form having horizontal portions securedto member 28 by headed screws 30. A member Si is secured between the vertical portions of brackets 29 by a headed and nutted bolt 32. Member 3| extends between members It and 28- and is also. secured to ,a bar 54 to be later described. Member! comprises oppositely disposedwportions 3| a. having the general form of segments in vertical cross section, the chords of said segments being, substantially vertical so that, said portion-sv have outer convex surfaces which are closer together at their tops and bottoms than. at the intermediate or central portions. of; said member 3 I.

A block 35 is pivoted between theupper endsvof brackets 29 by a 36 and 40, bar 38 has a cylindrical portion on which are journaled oppositely extending curved arms 42 and 43. Said arms are oppositely disposed with their concave sides facing each other and are connected by a tensile coiled spring M. There are a pair of arms 42 and 3 at each end of bar 38. Said arms 42 and 23 at their free ends are bored to receive the reduced ends of rods 43 shown as of cylindrical form. Rods 35 have surrounding the same resilient or yielding sleeves l"! of rubber or similar material. Bar 38 has mounted thereon for sliding movement a yoke 58 made of plate-like material, the same extending across the top and along the sides of bar 33 and having depending spaced portions Mia between which extends a headed and nutted bolt 50 forming a journal for a cutting disk 55, the lower portion of which is adapted to travel between the portions 3la of member 3|. Spaced bars 53 are secured to cabinet l5 and extend forwardly therefrom beneath and adjacent one of the shelves l5dd, said bars 53 supporting at their forward ends a bar 54 which extends longitudinally beneath member 3!, said bar 54 having its ends downturned and secured to members 53 and 28 respectively by headed and nutted screws 59. Bar 54 is secured to the bars 53 by small countersunk screws 55. A roller 5? has reduced end portions journaled in brackets 58 secured to the ends of shelf lfidd. A rod-like bracket 60 is secured to cabinet l5 and to the top of the top wall somewhat adjacent one end wall and projects forwardly substantially the same distance as member 5.

In operation, the rolls of oilcloth or similar material 65 will be disposed in compartments E5 the same being shown as carried on tubular cores 56, said rolls resting against the rear wall 5a. When it is desired to dispense a piece of cloth, the particular roll will be placed on shelf lEidd. The free edge of the cloth 65a, will be carried over roller 5? and the cloth drawn out over member 3!. The measuring roll 22 which normally stands in position with rod 20 vertical as shown in dotted lines in Fig. 1, will now be lowered onto the cloth and will rest upon the same on the end bar 53. The operator will draw the cloth forward to the roller formed by the portions 271. The edge of the cloth can then be inserted in one of the slots 217. The operator can now turn crank 27h in a direction to wind the cloth on the roller formed by portions 212' Care, of course, will be taken to see that the cloth is squared with the roller and withmember 31 and this can easily be accomplished by observing the pattern on the cloth. The cloth will be moved forward by turning crank 21h and the cloth will move under the measuring roller 22 and turn the same so that the cloth will be accurately measured. When the desired amount of cloth has been drawn from the roll the operator will take hold of bar 38 and attached parts which normally rests on the bracket 60. Member 38 together with the rollers 41 will now be lowered and rolls 47 will move into engagement with the cloth pressing it down around the sides of member 3!. The rolls 4'! move down to the position shown in Fig. 6 so that they remain in this position, being below the widest part of member 3!. The cloth is thus drawn taut over the top of member 3!. The operator now takes hold of member 58 and moves the same with cutter 5! along member 38, cutter 5| moving between the portions of member 3| and severing the cloth. The cloth is cut with a nice clean cut and as the cloth is held taut it is an easy operation to move the cutter along through it. It will be seen that member 31 can cooperate with cutter thus acting as a cutter. The operator can now turn crank 21h to wind upon the short end of the cloth on the roller and the roller and cloth thereon together with shaft 21g can be lifted by moving members 2' rearwardly. The roll of cloth can now be slid endwise from the end of the roll formed by portions 2% opposite crank 21h. The'cloth is thus nicely rolled and can be easily and quickly wrapped up to be dispensed. As the cut edge of the cloth is at the top and central portion of member 3! it will be measured from this point when it is again drawn out. The measuring roll 22 can thus be set on the cloth and again set for zero feet and zero inches. The bar 38 is accurately positioned in its holding function by the pin M entering the recess in member l6. After the material is severed the bar 38 and attached parts is again raised and placed on bracket fill.

It may be desired to furnish a core on which the dispensed cloth is wrapped. If this is the case such a core as shown in Fig. 14 is used. The members 34 and 35 can be placed in the core 33 as shown, shaft 219' with its attached roll andv crank Z'lh may be removed from brackets 21 as already described and the core 33 with shaft 35a, shaft 34?) and crank 34d can be placed in the brackets 21. Shafts 35a and 34b will be held by the portions 2'52 and the member Elf as already. described. The operator will have to start the edge portion of the cloth about the core 33 to begin the winding operation by means of crank 34d. Otherwise the cloth is drawn out by operation of crank 34d just as has been described by operation of crank 21h. When the desired amount of cloth is wound on core 33, the same can be removed as already described after which members 34 and 35 will be removed from the core. The core 33 with the cloth wound thereon can then be wrapped and dispensed as desired.

From the above description it will be seen that I have provided a very simple and efficient device for measuring, holding and severing material which is of the soft or limp nature, such as oilcloth. The material can be easily and. quickly drawn from the roll, accurately measured and quickly cut and dispensed. The operation of handling the cloth or dispensing the same is greatly simplified and the time required is greatly reduced. The operator can observe how the pattern of the cloth lines up with the rolls 4! or other longitudinally extending parts so that he can be sure that the cloth will be cut by cutter 5| at right angles to the edges thereof. The device is simple in construction and can be easily attached to cabinets or other holding devices where the material is kept. The device has been amply demonstrated in actual practice and found to be very successful and efficient.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which generally stated, consists in a device capable of carrying out the objects above set forth in the parts and combinations of parts disclosed and defined in the appended claims.
