Specification of Letters Patent.

Patented Dec. 29, 1908.

Application led April 6, 1906. Serial No. 310,323.

The object of my improvements is to provide a simple device of the character set forth which will be inexpensive in construction, effective in use, convenient and durable, and which Will reduce to a minimum the frictional resistance to be overcome in cutting a piece of paper from the roll.

In the drawings-Figure 1 is a perspective view of a multiple vertical-series cutter embodying my improvements. Fig. 2 is a side view of a single cutter embodying the same.

features of construction. Fig. 3 is a vertical cross-section taken through Fig. 2. Fig. 4 is a detail horizontal sectional view, taken on the line x-, Fig. 3. Fig. 5 is a detail horizontal sectional view, taken on the line y-fy, Fig. 3. Fig. 6 is a detail sectional vview showing the detachable connection between the lower stationary member and the upper revolving member of the base, and the portion which enters the lower end of the bore of the roll of paper.

Corresponding parts in all the figures are denoted by the same reference characters.

Referring to the drawings, 1 designates a horizontal base, which is preferably constructed of metal and in one piece. in the top of this base is provided an annular groove or channel, 2, preferably in a central raisedportion, as at 3, and a series of balls, 4, are seated in this channel. A cylindrical stud or pin, 5, projects upwardlynfrom the base 1, centrally with respect to the series of balls 4 and above the latter. The stud 5 is in secure connection with the base; the connection may be formed by threading the stud in a threaded opening in the base 1, as at 6, or in any other suitable manner.

7 designates a supplementary revolving base, which may consist of a metallic plate, turnably mounted upon the projecting stud 5 and adapted to support the roll of paper (shown at 8) in vertical position. The supporting base 7 bears upon the series of balls 4, its under side resting thereon, preferably at a central annular downwardly-extending enlargement, as at 9. From the top of the base-member 7 projects a cylindrical extension, 10, surrounding the opening, 11, in the base 7 for the stud or pin 5 and also surrounding said stud. This extension 10 forms a stud upon the base-member 7, which projects within the bore (shown at 12) of the roll of paper 8 at the bottom, to retain the roll in position. The projecting top-end, 14, of the stud or pin 5, above the extensionstud 10 of the base-member 7, is preferably threaded and carries a nut or tap, 15, whereby the base-members 7 and 1 are detachably but operatively' retained together and displacement of the balls 4 either in operation or during transportation of the device is prevented g in lieu o`f the threaded end 14 and tap 15 a permanent head may be provided upon the stud 5, if desired.

The base-portion of the device, constructed according to my improvements as above described, provides an effective counter-balance or weight against the weight of the roll of aper for retaining the latter in its u rig t or vertical position; or, if desired, t e base 1 may be suitably secured or fastened to a store-counter or other support.

16 designates a standard, which rises from the base 1 at one side the revolving basemember 7. The lower end of this standard may be connected to the base 1 in any suitable manner, preferably detachable; the connection may be by threading the lower end, 17, of the standard 16 into a threaded opening, 18, in the base 1. The standard preferably consists of a metallic cylindrical bar bent at right-angles at its upper end, as at 19, to form a horizontal top arm, 20, projecting above the top of the roll of paper. At its outer end said arm 2O carries a tubular T-piece, 21, the main cylindrical bore, 22, of which registers vertically with the stud 10 of the base-member 7, while its side bore, 23, receives the end of the arm 20. The endpiece 21 may be connected with the arm 20 in any suitable manner; for instance its bore 23 may be threaded upon the end of the arm 20, as at 24.

25 designates the knife or cutter, which is mounted vertically and carried by the standard 16 it may consist of a metal blade having an outer longitudinal cuttin -edge, 26. The blade 25 is carried by latera arms, 27 the ends of which embrace the standard 16, as at 28, and have a turning bearing thereon, whereby the blade is pivotally mounted with relation to the standard and with relation to the roll of paper. The cutting-blade is sustained in position, and held with its cuttingedge constantly bearing against the side of the vertically-mounted roll of paper, by means of springs, 29, which may consist of a coil, 30, surrounding the standard 16 and having one end, 31, connected to the standard and the other end, 32, projecting outwardly and against the cutter-arm 27. The bearing-ends 28 of the arms 27 rest upon the s ring-coils 30 and are supported thereby.

he ends 31 of the springs 29 may simply be sprung into retaining recesses, 33, in the side of the standard 16, and the outer projecting ends 32 of the springs may be turned to pass under the cutter-arms 27 as at 34, and angularly bent to provide an upwardly-projecting end, 35, which bears against the side of the arm 27 36 designates a holding-pin, which is slidably inserted in the vertical bore 22 of the standard-end 21 and is rovided with a supporting or retaining head or handle, 37. The downwardly-projecting cylindrical orl tion, 38, of this pin 36 is received by the ore 12 of the roll of paper 8 at the top, and operates in conjunction with the stud 10 of the revolving base-member 7 (which supports and carries the roll of paper) to retain the roll at all times in vertical operative osition against the tensional bearing of the nife or cutter 25.

lt will be noted that in the construction of my improved paper-cutter as herein described, the base-portion, standard, cuttingmechanism, and holding-pin are all readily separable'or detachable, for convenience and economy in space in aching and transportation, and that, Wh e the revolving basemember 7 is secured in connection with the fiXedbase-member 1 by the pin or stud 5 and its tap or head 15 so that the ball-bearing members 4 are retained at all times between the members 1 and 7 and so retained during transportation of the device, the members 1 and 7 ma be separated or detached and the balls 4 reliaased when desired.

In the improved multiple vertical-series constrii ction comprised in my invention, as illtstrated in l ig. 1, intermediate base-members, as at 39, are carried by the standard 16 at points between the bottom standard-carrying base and the top of the standard, and

individual cutter-mechanisms are mounted intermediately of said separate bases. This construction of my invention and improvements enables the carrying of different rolls 'of paper,'as at 8, in vertical series upon one device; the rolls may be of different sizes, as

shown, and placed so that in the series-arrangement of the rolls the lighter or smaller rolls are respectively above the heavier or larger rolls. The base-member 1 of the bottom standard-carrying base will be, in this multiple construction, relatively larger and heavier, to provide a irm rest and proper stability for the vertical series of rolls, and the intermediate base-members 39 may be relatively of a size adapted to the size of the rolls they are designed to carry. These intermediate bases 39 are preferably mounted upon and carried by the standard 16 in an a justable and separable or detachable manner, for which purpose they can be provided with an eye or opening, 40, in their stationary member 1 at one side their revolving member 7, corresponding to and receiving the cylindrical standard, a set-screw, as at 41, being provided and projecting into said opening 40 to engage the standard and secure the base 39 in its supported position; this adjrstability enables variation in the position of the bases 39 to provide for variable sizes of the rolls of paper rsed. In this multiple constriction of' my invention, the standard 16 is extended vertically with respect to the complete vertical series of rolls 8, and the intermediate bases 39 may carry a cylindrical pin or sttd, as at 42, projecting downwardly from the bottom of the fixed bottom-member 1 of the base 39 and entering the top portion of the bore 12 of the neXt roll of paper 8 underneath. This pin 42 thrs serves th same office as the top holding-pin 36; it may, if desired, be simply a downward extension of the str d or pin 5 which is carried by the base-member 1 and upon which the revolving b ase-memb er 7 is turnably mounted. lf the bases 39 are adji sted in variable position, to provide for variable sizes of the rolls of paper i sed, a corresponding adji stment for the crtting-mechanisms may be enabled by providing r pon the standard a vertical series of the retaining recesses 33 in which the ends 31 of' the springs 29 are set. This adjustable The operation and advantages of myV improvements will be readily understood. Paper-cutters in which the roll and cutter are horizontally placed have the weight of the roll of paper upon the horizontal bearings or aXles at each end, which multiplies and increases friction when the roll is revolved to cut 0H a piece of paper. In a cutter constructed according to my invention, the roll of paper and cutter are both placed vertically and no part of the weight rests on axles or pivots, the whole weight of the roll being borne by the horizontal revolving base-member 7 which rests upon an antifriction ball-bearing. The studs or pins entering the respective ends of the bore of the roll of paper serve merely as retaining devices for the roll in its turning movement upon its supporting base; there is only one l bearing, and that is provided at the bottom anti-friction ball-bearing construction, thus insuring ease of manipulation and a minimum of friction so that very slight power is required to revolve the roll of paper. Convenience and facility in measuring the paper to be cut off is also Ifacilitated by the vertical position of the roll, and the improved construction enables the insertion or removal of a roll of paper with ease and facility. Mashed or tangled rolls of paper can be easily used and operated, as no axle or bearing-rod need be forced through the roll in mounting it upright in the cuttingdevice. To insert a roll of paper, it is simply necessary to draw back the springactuated cutting device and seat the roll with its bottom end upon the revolving base-member 7 with the projecting stud l() thereof entering the bore of the roll at the bottom, then slide the top holding-pin 36 downwardly into the bore of the roll at the top, and then release the cutting device so that its 1Knife-edge will continuously press by sprin tension against the outer surface of the ro l; the edge of the paper can then be grasped to turn the roll and the desired sheet cut od against the cutter-edge. There is no strain on the standard or roll-holding members, as the whole weight of the vertically-mounted roll is upon the bottom revolving ball-bearing base-member 7.

I do not desire to be understood as limiting myself to the detail construction and arrangement of parts as herein shown and described, as it is manifest that variations and modifications therein may be resorted to, in the adaptation of my invention to varying conditions of use, without departing from the spirit and scope of my invention and improvements. I therefore reserve the right to all such variations and modifications as properly fall within the scope of my invention and the terms of the following claims.
