PAPER-ROLL HOLDER AND CUTTER.

Specification of Letters Patent. Patented Dec. 23, 1919.

Application filed February 26, 1919. Serial No. 279,292.

To all whom it may concern: 7

Be it known that I, ELVAH O. BULMAN, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Paper-Roll Holders and Cutters, of which the following is a specification.

The present invention relates to paper roll holders and cutters; and its object is, generally, to provide an improved device of that character; and more particularly, to provide improved means for holding the swingably mounted cutter of such a device in non-contacting relation with the paper roll; and further, to provide improved supports for the paper roll; and further, to provide an improved cutter for such a device; and further, to provide improved means for detachably connecting the members of such adevice.

This and any other objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the struc ture hereinafter described and illustrated by the accompanying drawings, in which Figure 1 is a front view of a paper roll holder and cutter;

Fig. 2 is a sectional view of the same taken on a vertical plane corresponding to line A of Fig. 1, and showing the cutter (partly broken away) in raised position; V

Fig. 3 is a like view, but showing the cutter in lowered or operative position; and

Fig. 4; is a sectional view of certain parts taken on a vertical plane corresponding to line B of Figs. 2 and 3.

In the embodiment of the invention chosen for illustration by the drawings and for cletailecl description in the body of this specification, the paper roll holder and cutter comprises a pair of metallic supports 1, 2, having upright portions 8 with inwardly turned strengthening flanges 32, 33, and horizontal portions 4, 5 at their upper and lower ends respectively, and also comprising pedestals 6, 7 to which the lower horizontal portions 5 are fastened, preferably detachably as by bolts 8. The pedestals have downwardly extending strengthening flanges 9 with openings 10 therethrough. The supports 1, 2 with their pedestals are detachably fastened together, for assembling the parts, by a connecting bar 11 whose ends extend through such openings and are secured to the pedestals as by bolts 12.

A second connecting member for the sup-- ports is desirably provided, as the wooden bar 13 to which the upper horizontal portions 4: of the supports are fastened as by u screws 14.

The supports have open top sockets 15 adapted to receive the opposite ends of the horizontal spindle or axle 16 on which the paper roll 17 is carried. The upper portions 18 of the supports are spaced apart farther, as shown, than the portions 19 of the supports adjacent said sockets, in order that the ends of the axle may be more readily inserted into and removed from the sockets. The meeting angle of the upright portions 3 and the horizontal portions 4, 5 of the supports is strengthened by a rib 20 inclined toward both meeting portions and formed by inwardly bending or upsetting the metal of which said supports are made.

The cutter, designated generally 21, whereby a strip of the paper roll may be severed, comprises the arms 22, the heavy body member 23 into whose ends the arms are dovetailed at 24;, and held as by upsetting the mouths of the dovetail mortises over the extremities of the arms, and also the thin me tallic cutting member 25 carried by the body member. Adjacent its cutting edge 26 this cutting member is convexed at 27 toward the work or paper roll, so that in turning the roll, the paper will not tearingly engage the cutter and be marred thereby.

The supports 1, 2 are provided with pivot pins 28, and the arms 22 have elongated slots or bearings 29 whereby the cutter may turn and slide on the pivot pins: A stop 30 (as a part of the flange 32) is so positioned relatively to the pivot pin that the cutter may be slid to one position (shown in Fig. 2) on the pin wherein the cutter (2'. e." the extremity 31 of its arms 22) engages the stop and thereby the raised cutter is held against falling, and out of contact with the paper roll. In this position of the cutter paper rolls may be easily inserted into the device. But when the cutter is slid to another position on the pin, (shown in Fig. 3) it is in operative position and is freely swingable and falls by gravity into contact with the paper roll.

Theinvention being intended to be point ed out in therclaims, is not to be limited to or by details of construction shown or described.

I claim 1. In a device of the character described; a support having a pivot pin; a swingable cutter having .an elongated bearing extending obliquely transversely thereof turnable and slidable on the pin; a stop positioned adjacent the rear end of the cutter and lower than the-pin, so that the cutter may he slid on the pin to one position wherein the cutter is held against falling by the stop, and to 7 another position wherein the cutter is freely l5 swin 'able. v

2. ln a device of the character described; a support; a cutter comprising supporting arms swingably mounted on the support, a body member, and a thin metallic cutting member carried by the body member and having a portion adjacent its cutting edge convexing toward the work.

In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan, this 25 21st day of February, 1919.

ELVAH O. BULMAN.
