PAPER-ROLL SUPPORT ro WRAPPING Am) otrHnR MACHINES.

Application filed June 2,

This invent-ion relates to machines which operate on sheet material in the form'of a web wound or coiled in supply rolls and intermittently drawn therefrom for treatment bythe machine which acts'on the web either to cut sections and to wrap articles such as bread in. the sections, or to print on the web or on sections thereof, or otherwise opcrate on or treat the Web. For convenience,

10 the material of the Web willbe hereinafter referred to as paper, althoughI do not limit myself, to the use of the invention in connection with web rolls of paper. In many machines ofthe character or characters referred to, the support for the roll of paper is located in somewhat inaccessible places, such asbeneath other parts of the machine, in order to permit the paper to be properly and smoothly fed tothe machine from the supply coil or roll. The supply rolls are heavy and much effort and stooping movements are necessary to place a roll on a support so located. In many bakeries which employ bread wrapping machines, girls andwomen are employed to attend the machines, and it is hard work for them to place a supply roll or paper on a support located under operative parts of the machine.

The object of the present invention is to facilitate the placing of supply rolls of paper on the supports therefor, and I attain this object by providing a support which, when it is to be loaded, can be first swung out to accessible position, the roll then mounted thereon," and the support then swung back to its proper position for the operation of the machine.

With said object in View, the invention consists in theconstruction and combination of parts substantially as hereinafter described and claimed.

Of the accompanying drawings Figure 1 is a perspective view of theinvention in its relation to the frame of a machine which operates on a web of paper.

Figure 2 represents a section taken about midway of the roll support.

Similar reference characters similar parts in both figures.

Integral 'withor rigidly secured to the frame of the'machine of which the present invention is a part, are arms a'having cars a in which a vertical pintle Z) is mounted.

Also mounted on the pintle are arms'c of a frame d, said plntle forming a hinge connection to perm t the frame 0, d, to be swung in a substantially horizontal plane.

of the shaft 9 of the paper roll, said sockets being so formed as to'permit an exhausted roll to be lifted therefrom and a fresh one to be substituted therefor.

Near the catch pin it is a stop lug 2' projecting inward from the main frame of the machine in position to arrest movement of the frame 0, d,when the latter is swung to came; the recess in the lug e to'engage the in Preferably, but not necessarily, the swinging frame also carries plates k slotted for rods k which are employed for preserving tension in a loop of the web 00 led from-the roll to whatever mechanism is to draw the paper from the roll. 1 At one end, the shaft 9 is illustrated a having one or more pulleys Z from Which a weight on is suspended by means of atband or strap a to act as a brake on the pulley of the shaft 9 to prevent too free unwinding of the web as. I

When the machine of which the swinging roll support forms a part is in operation, the said support occupies the position illustrated by Figure 1. When a fresh roll of paper is needed, the attendant, of course, stops said machine. Then the swinging support is swung away from the catch pin h and as far out to one side of the main frame as may be desirable to permit the exhausted roll shaft to be lifted out from the sockets f, the swinging frame being then in position to permit a fresh roll of paper to be easily deposited trated.

Vhen tension rods such as illustrated at k thereon, after which the attendant only needs to swing it back to the position illus are employed, the attendant can easily,

while the frame is swung out, draw the end of the paper web under the lowermost of said rods and pull it up far enough to lay the end of the web on top of the roll. Then, after swinging the frame back to its operative position, the end of the web is readily accessible for threading it to the members. of V the machine which feed the paper from the roll as illustrated, for instance, in the application Serial- No. 89,319, filed February 19, 1926, by Sevigne 8: Chabot.

The shifting of the swinging frame from its operative position out to accessible replenishing position and back again to. open tive position requires but a few seconds, and the operation of effecting replenishing while the support is in outward swung position is effected as easily as though no machine for using or operating on the paper was present.

Having now described my invention, I claim: 7

1. 'A paper roll support having an axially vertical hinged connection with a side portion of a stationary machine frame and having sockets in alineinent for the ends of a roll shaft.

ed on a, vertical axis at one end to a side portion of a stationary machine frame and having means at its other end for holding it in useful operative position, and having means at both ends for supporting the core shaft of a roll of paper.

3. The combination with the frame of a machine which is to be supplied with web material in the form of rolls, of a roll-supporting frame pivoted on a vertical axis to a side portion of the machine frame and adapted'to be swung to and from operative position, said pivoted frame having a socket at each end to receive the ends of a core shaft of the roll of paper.

a. The combination with a stationary machine frame, of a roll-supporting frame pivoted on a vertical axis to a sideportion of the machine frame and adapted to be swung to and from operative position, said roll-supporting frame carrying tension devices for the web led from the roll.

In testimony whereof I have affixed my signature.
