NITED STATE FEEDING ATTACHMENT.

Application filed April 5, 1922.

To all whom it may concern:

Be it known that I, LAWRENCE B. GRAS- BERGER, a citizen of the United States, residing at the city of Richmond, in the State of Virginia, have invented certain new and useful Improvements in Feeding Attachments, of which the following is a specification.

This invention relates to feeding attachments for roll holders used in stores for supplying wrapping paper in sheets as required; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed, whereby the paper roll is revolved a little so as to make. the free end portion of the paper protrude below the tearing-off blade, where it can be grasped by hand, and simultaneously to raise the blade clear of the paper.

In the drawings, Figure 1 is a front view of the upper part of a roll holder provided with a feeding attachment according to this invention. Fig. 2 is an end view of the attachment drawn to a larger scale and showing the blade in section, and with the feed roller pressed against the roll. Fig. 3 is a front view of the parts as shown in Fig. 2.

The feeding attachment can be applied to many makes of roll holders, both horizontal and vertical. In the example shown, the roll of paper 6 is horizontal, and it is journaled in a frame 7. A blade 8 is secured to arms 9, and bears on the periphery of the roll. The arms are pivoted to the frame by pins 10, and the paper is torn off against the bottom edge of the blade. The roll requires to be revolved a little after a sheet of paper has been torn from it, so that the loose end of the paper can be grasped by hand.

A. bracket 12 is pivoted to the blade 8, and projects upwardly of the blade at the middle part of its length. The lower part of the bracket is preferably pivoted by a pin 11 to a hinge plate 15 which is secured to the blade. and the plate 15 has a stop lug 16 which bears against the bracket and prevents it from being moved too far away from .the roll. A spring 17 is provided for pressing the bracket away from the stop lug, and any kind of a spring may be used for that purpose.

A pivot roller 18 is j ournaled in the frame adjacent to the hinge pin 14, and it and the Serial No. 549,864.

blade are normally held in contact with the roll of paper. A feed roller 20 is journaled in the upper part of the bracket, on the other side of the pivot roller from the hinge pin, and is preferably a wooden roller covered with india rubber.

After a sheet has been torn from the roll, the roller 20 is pressed by hand against the roll, and is revolved by the hand in the direction of the arrow in Fig. 2. This raises the blade clear of the roll, and turns the roll so that the loose end 21 of the paper can be grasped with facility.

What I claim is:

1. The combination, with a frame for supporting a roll, and a blade pivoted. to the frame and adapted to bear on the roll; of a bracket pivoted to the blade and projecting upwardly of it, a pivot roller journaled in the bracket, and a feed roller journaled in the bracket above the pivot roller and normally supported clear of the roll, the said blade being raised clear of the roll when the feed roller is pressed against the roll.

2. The combination, with a frame for supporting a roll, and a blade pivoted to the frame and adapted to bear on the roll; of a bracket pivoted to the blade and projecting upwardly of it, a pivot roller journaled in the bracket, a spring which normally holds the pivot roller in contact with the roll, a stop which limits the movement of the said bracket away from the roll, and a feed roller journaled in the bracket above the pivot roller and normally supported clear of the roll, the said blade being raised clear of the roll when the feed roller is pressed against the roll.

3. The combination, with a frame for supporting a roll, and a blade pivoted to the frame and adapted to bear on the roll: of a hinge plate secured to the said blade, a bracket pivoted to the upper edge of the hinge plate, a pivot roller journaled in the lower part of the said bracket. means for holding the pivot roller in Contact with the roll, and a feed roller journaled in the upper part of the bracket and supported clear of the roll while the said blade is in contact with the roll.

In testimony whereof I have aiiixed my signature.
