FRANK H. HOBERG, OF GREEN BAY, WISCONSIN.

FEEDING-CABINET.

Specification of Letters l atent.

Patented Mar. 21, 1916.

Application filed October 19, 1914. Serial No. 867,274.

To all whom it may concern:

Be it known that I, FRANK H. HOBERG, a citizen of the United States, residing at Green Bay, county of Brown, and State of Visconsin, have invented new and useful Improvements in Feeding-Cabinets, of which the following is a specification.

My invention relates to improvements in feeding cabinets for rolled paper packages of that type in which the lower end of the cabinet is open and sheets of paper are permitted to drop and hang through the opening, whereby the sheets may be successively grasped and torn off from the remainder of the package.

1 In a former application. filed by me April 17th, 1914, Serial No. 832,415, I have shown and described a roller, having a frictional bearing surface, and supported by a reciprocating carrier, said roller being free to rotate in one direction only and the carrier being reciprooated to cause the roller to move forwardly, engage the sheet and push or draw it backwardly until the end of the sheet is delivered from the top of'the package and permitted to hang in a position where it can be grasped and torn off.

The object of the present invention is to provide means for utilizing a brush for the purpose of frictionally discharging the.

sheets.

In the drawings.Figure 1 is a transverse sectional view of a paper cabinet embodying my invention, showing a roll of paper therein. Fig. 2 is a longitudinal sectional view of the same, showing'the roll and feeding apparatus in elevation. Fig. 3is a detail perspective view of the frictional paper feeding member. Fig. ,4: is a detail side view of a modified form of brush.

Like parts are identified by the same reference numerals throughout the several views.

T he cabinet Walls preferably comprise a back wall A, end walls B and a cover wall C. The latter forms the front and top of the cabinet. It is hinged to the end walls B at 5. The package Dis wound upon a core E, which is supported from the cabinet in any suitable manner by a holding plate F. The plate F preferably extends through a slit in the core E, a portion f of the plate being partially severed and offset to pass through the slit. This plate is therefore adapted to prevent the package from rotating upon its support. But the present inangular position.

vention is not dependent upon any specific means for supporting theroll of paper and these features therefore require no further description. The package D illustrated in the drawings is partially severed at G, G, near the upper end of the front side. The outer sheet (1 of the package is permitted to hang through the open bottom of the cabinet as shown, whereby it may be grasped and removed by tearing it across the tongues 9, thus severing it from the next succeeding sheet. When the first sheet is torn away, the upper end of the succeeding sheet might drop and hang by gravity in substantially the position occupied bythe first sheet d, but owing to the fact that this upper end partially over-laps the top of the package and also-owing to its frictional adhesion to the sheet beneath it, the dropping of the free end cannot be relied upon. It is also undesirable that it should drop automatically for the reason that the paper might then be too easily Withdrawn and waste or theft would be facilitated. I therefore provide a frictlonal bearing member in the upper portion of the cabinet, which consists of-a brush pivotally connected with an'actuating member in the rear of the package. The brush is preferably composed of short pieces of wire H, secured to a suitable back, and having a half elbow at h, with the free ends of the wire projecting in'the direction in which the sheet is to be discharged. I do not limit the scope of my invention to wires or bristles, which are intermedially bent, nor to the feature of having any portion thereof in an It is obvious that the wires or bristles may project angularly directly from the back of the brush if so desired, as shown in Fig. 4. These free ends of the wire or bristles of the brush rest upon the outer sheet and support the brush from the roll of paper. The back of the brush preferably comprises a flexible portion H in which the wires or bristles are embedded and secured, and also a rigid metal back H, formed with side flanges h, which are bent inwardly and engage the margins of the flexible backing H, as clearly shown in *Fig. 3. This metal back H is provided with a projecting arm I at one end, which is loosely engaged with a crank J at J, said crank constituting a part of a crank shaft K, which has bearings in the respective ends of the cabinet. WVith this construction it is obvious that a rotation of the crank shaft sheets.

will cause-the brush to reciprocate up o ri t he surface of the paper.

at M and adapted to be 'a'ctuated'in' one direction by a handle N, connected with an arm 0 of the segment by a cord or other flexible connection P. Ascoiledspring Q.

has one end secured to the segmentand the other end to the end wall of the cabinet in a position to retract the segment after it has been manually actuated by pulling. upon the handle or knob N. When the operatorpulls downwardly upon the handle or knob, the brush will be reciprocated uponthe surface of the paperadjacent to or across the. line of the slits G, G, the bristles or wires pro-o jecting angularly in a direction to engage and pull the paper away from the slit at that side occupied bythe free end of the succeeding sheet after the preceding sheet has been torn off. The free end of thesucceeding sheet will therefore be drawn away from the surface. of the roll and discharged,

to a hanging position below the cabinet. It.

will therefore be understood that, the device operates in a manner quite similar, to the dis-s charging device shown and described in-said' former application, but the brush constitutesv the immediate agency for discharging the Owing to the angular position of the paper engaging portion of the wires or bristles, the brush moves over the paper in one direction without forcibly engaging it, sincethe points of the Wires or bristles will yield freely under such conditions when. subject to slight resistance. But when moved,-

in the opposite direction, these pointstend to enter the paper, and this tendency may be increased or diminished by changingthe weight of the brush.

In Fig. 4 the brush is composed-ofshorth bristles, secured to the back preferably in an angular position.
