Application January 4,

3 Claims.

This invention relates to a cloth bolt machine,

"and has for the primary object the provision of a device of this character which will permit easy and quick removal of a desired length of cloth from a bolt of cloth and further permit the desired lengthof cloth to be accurately cutfrom the remaining cloth of the bolt of cloth and to remove the selected length vof cloth in a folded condition ready for wrapping.

With these and other objects in view, the invention consists in certain novelfeatures of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure l is a side elevation illustrating a cloth bolt machine constructed in accordance with the present invention.

Figure 2 is a top plan view illustrating the machine.

Figure 3 is an end elevation illustrating the machine.

Figure 4 is a sectional view'taken on the line 4-4 of Figure 2.

Figure 5 is a sectional view 5-5 of Figure 2.

Figure 6 is a fragmentary transverse sectional view illustrating the means of supporting the cloth while cutting. I

Referring in detail to thedrawings, the numeral 5 indicatesfthe base of a machine on which is mounted a supporting structure 6 especially constructed for the supporting of a bolt of cloth taken on the line as illustrated at l and consists of relatively spaced elongated plates 8 which have their upper edges formed to slope in opposite directions pro viding inclined faces A and stop faces B coacting with each other in supporting a bolt of cloth as clearly shown in Figures 1 and 4 so that the bolt of cloth will be free to rotate thereon when removing cloth therefrom.

Mounted on the base 5 are vertically-arranged standards 9 providing a journal for a horizontally arranged shaft ill on which is mounted for free rotation a main cylinder ll of a length substantially equal to the width of the base and is provided at one end with a handle 12 eccentrically located with respect to the shaft ID for the rotation of the cylinder II.

A clamping member I 3 in the form of a leaf 1939, Serial no. 249,338

cylinder substantially throughout the length thereof. The free end of the clamping member extends out of the groove so'that it may be gripped for flexing into the dotted line position as shown in Figure 3 to permit the cloth to be positioned thereunder and when freed is adapted to clamp the cloth on the periphery [of the cylinder so that the cloth during the rotation of the cylinder willtbe caused to wind from the bolt onto the cylinder.

The external diameter of the cylinder is of'a selected measurement and secured thereto and operating between flanges I5 provided on said cylinder II is a measuring tape IS. The measuring tape extends from the cylinder H and is wound on a spring influenced drum l'l journaled on arms I 8 forming an integral part of the standards 9 and arranged in a plane below the cylinder so as to'support the drum l'l laterally of the cylinder I l and in a plane below the latter. A clock type spring I9 is used for driving the drum IT in one direction and in a direction to wind the tape l5 onto said drum and also to position the cylinder ll readyto'receive the end vof the cloth from the bolt of cloth. The cylinder I when rotated to wind the cloth from the bolt onto the cylinder, the tape also will be wound onto said cylinder which will indicate the lengthof material wound on the cylinder permitting the operator to easily determine'when a desired length of material has been wound on the cylinder H from the bolt of cloth. Also, if desired the tape It? may be provided with a calculating table (not shown) to permit the clerk or operator to easily determine the price of the amount of cloth which has been wound onto the cylinder. v

A cloth cutting frame 29 of substantially U shape is pivotally mounted by having one end pivoted on one of the uprights 9 and its other end pivoted on an upright 2i carriedby the base 5. Normally when the cutting frame is not in use 1 it occupies a horizontal position resting in notches 22 provided in the plates 8 of the rock or support 6. The frame may be swung from the horizontal position to occupy a position with the bight portion disposed over the cylinder I I and under the cloth, as shown in dotted lines in Figure 4. The bight portion or the frame is of a tubular construction and is provided with a slot 23. The cutting frame on being moved into the latter-named position, the bolt of cloth is lifted and it passes under the cloth, as shown away from the cylinder H and by-using a knife or some other similar cutting instrument, as

in dotted lines in Figure 4, elevating the cloth shown in Figure 6, the cloth may be readily cut transversely thereof, the slot 23 permitting the cutting instrument to pass freely through the cloth and bring about an efiicient severance of the cloth and also acting as a guide for the movement of the cutting instrument across the cloth so that the cloth will he cut with straight ends.

A dog 25 is pivotally mounted on one of the standards 9 and normally rides the teeth of a gear 26 secured on one end of the cylinder H for the purpose of preventing the cylinder from rotating under the influence of the clock-type spring l9 when manually freed. However, this dog will permit the cylinder H to be manually rotated in a direction for winding the cloth onto the cylinder from the bolt of cloth and its purpose is to hold the cylinder H against rotation during the time of severing the cloth on the cutting frame and prior to removing the cloth from the cylinder which has been wound thereon.

After the cloth has been wound onto the cylinder H from the bolt to a desired length, which may be easily determined by referring to the tape measure it, and after the severance of the cloth which is on the cylinder in the manner heretofore described, the operator pulls the cloth on the cylinder off of one end thereof or the end, having the handle 12. The cloth removed from the cylinder in this manner when laid on a counter will assume a folded condition ready for wrapping.

After the first operation of removing from the bolt'of cloth a desired length of cloth and severing the same from the cloth of the bolt of cloth through the use of the cutting frame, the latter is returned to its normal position within the notch 22, by removing the bolt of cloth from the rack 53. The operator then releases the dog from the teeth of the gear and the drum H is returned to its initial position by the influence of the spring i9 which also winds the tape measure onto the drum l1.

It is believed that the simplicity and advantages of this invention will be perfectly apparent to those skilled in the art to which such device relates, and while I have herein set forth a satisfactory embodiment of my invention, it is to be understood that such changes therefrom as fairly fall within the scope of my claims may be resorted to when desired.

What is claimed is:

1. In a machine of the class described comprising a base, means for supporting a bolt of cloth on said base to permit the cloth to be unwound therefrom, a supporting means on the base, a cylinder rotatably supported by said supporting means and adapted to have cloth of the bolt wound thereon, clamping means on the cylinder for releasably securing the cloth thereto, a handle for rotating said cylinder and connected to the unsupported end thereof and so positioned as to permit the cloth on the cylinder to be removed from the latter in an endwisc direction of said cylinder after being severed from the cloth of the bolt, a substantially U- shaped frame pivotally mounted on said base and normally supported by said first-named means and capable of being moved in a position to substantially overlie and parallel said cylinder and to underlie the cloth passing from the bolt to said cylinder for raising the cloth from the cylinder and having a slot in which a cutting instrument may enter during the severance of the cloth on said frame transversely of the cloth.
