VERTICAL PAPER CUTTER.

Application filed June 15,

T0 (LU Hf/107M it may concern.

Be it known that I, h lnvxiinnin NELSON, a citizen of the United States, and resident of Littleton, in the county of Halifax and State of North Carolina, have invented certain new and useful Improvements in Vertical Paper Gutters, of which the following is a specification.

This invention relates to vertical papercutters such as are adapted to be used in stores, for carrying rolls of wrapping paper and cutting the desired lengths of paper from the rolls.

My present invention has particular relation to types of paper cutters such as that shown in my previous Patent No. 1,116,834, issued November 10, 1914, and some features of: the present improvements are adaptable for use in connection with paper cutters of the types shown in my co-pending applications Serial No. 552530, and Serial No. 625572.

The object of my present improvements is to provide a vertical paper-cutter of the type indicated, which will be especially adapted for carrying a plurality of rolls of paper and will at the same time be easily portable and operative upon glass counters, and will in its relative conditions of associate structure effect its own counter-balance and thus obviate any occasion for fastening the device to a counter or support or in the position in which it is mounted for operation. I

The improved cutter as comprised in my present invention is of a two-story type, and may be constructed in multiples or such two-story units to accommodate,. tor instance, four rolls of paper, and it is designed to occupy a minumum of space. or a very compact area in its multiple capacity. The improved cutter is especially adaptable for operative service with rolls ofsmall or moderate size, in contradistinction to very large or heavy rolls of paper, and it isturthermore structurally adaptable to he knocked-down into a compact space for commercial transportation and to be conveniently and easily assembled with its knocked-clown parts or members in eo-operative status to place the device in condition for use.

In the drawings I Figure l .is a perspective view of the multiple cutter embodying my present im provements.

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

I have herein illustrated the improved cut ter in a type of four multiples comprising two two-story units, but it will be understood that the cutter may be constructed in one one-story unit constituting two multiples. The four-multiple cutter is adapted to carry tour rolls of small or moderate size, and in practice would, for instance, occupy a counter space of approximately 6 by 1 inches, with a height of approximately 24 inches, for employment with tour rolls of small or what is known as baby roll paper, while for what are known as standard 9-inch-dimension rolls the device would be of approximately the same height but would occupy a counter space of approximately 9 by 24: inches. If constructed in the one two-story unit type, the dimensions of the counter space occupied would be correspondingly less. In all instances ot the multiples above noted, the structural conditions and relation are such that the device will effect its own counterbalance and will not require fastening means for mounting it in operative position upon the glass counter or other support.

The following detail description is related to one two-story unit, and will also describe the corresponding two-story unit in a four multiple cutter, said units being identical in their general features of construction.

Referring to the drawings, 14 designates a main horizontal base, which is stationary when the cutteris in operative use and which supports the entire body structure and mechanism of the device. This base is preferably formed of metal of suitable weight and is of suflicient. area to carry a two-story unit or units,- the construction being such in the instance of a four-1nultiple device that the base has two oppositelyextending platforms, as at -15, and its central portion intermediate of said extensions is provided with oppositely extending wing platforms, as at 1.6-16. li' designates a main vertical upright or standard which rises from the base 14 and carries the roll retaining and cutting mechanism of the device, this standard being positioned beyond the platform extension 15 of the main base 14. In the instance of a four-multiple device, the main standard 17 of one two-story unit will, in the preferred construction, be located at the inner end of one of the wing platforms 15 and tl e standard of the other two-story unit will be locatedat the outer end portion of the opposite wing platform 15, the standards and the units in which they are respectively comprised being thus arranged in series and not oppositely-disposed, which produces desirable conditions of counter-balance.

The standard 17 is secured at its lower end to the base 14:, preferably detachably, the preferredconstruction being such that the base carries projectively at its top a tubular stud, 18, through which and the base the lower threaded end of the standard is inserted and secured by a nut, 19, against the under side of the base, the top edge of the stud being notched or recessed at diametrically-opposite sides, as at 20'2(), to receive laterally-projecting pins or projections, 21 21, upon the standard, which pins seat in said notches and thus support and secure the standard within its socket-con nection.

Said standard carries at its top an arm or extension, 22, projecting laterally and carrying at its outer end a cylindrical socket which will be hereinafter described. The arm 22 is preferably a horizontal extension of the main rod constituting the vertical standard, and intermediat'ely of said top arm and the lower end of the standard is also provided a laterally-extending arm, 23, likewise carying a cylindrical socket at its outer end, the inner end of said intermediate arm being secured to the standard, preferably by connection with a collar, as at 24, carried upon the standard-rod and secured thereto by a clamp screw, as at 25'.

Above the, main stationary horizontal base 14 is carried a revolving base, 26, in

axial alignment in a vertical plane with the vertical bores of the cylindrical sockets at the outer end of the standard arms and 23, said revolving base being vpreferably 7 mounted upon ball-bearings, the preferred construction of which comprises a race track, 27, carried at the top ofthe' base 14 and carrying balls, 28, upon which the revolving base 26 rests and travels. The revolving base axially carries an upwardlyably formed of a metallic plate of suit-able contour and dimensions to suport the roll of paper, shown at 31, the lower end of which rests upon said base with the axial stud 29 thereof entering the bottom of the bore of the roll and thus forming'a keeper for positi-onally maintaining the roll.

The knife or cutting blade, as at 32, of the lower story of the two-story unit, as comprised in the general operative mechanism of the device, is carried the main standard 17 between the intermediate arm 23 thereof and said revolving base 26, the blade being of suitable construction to positionally bear longitudinally against the side of the paper roll and operate to cut the sheet which is taken therefrom, and the connection between the blade and the main standard be ing preferably by means of horizontal arms,

as at 33-33, in vertical series and conjointly carrying the blade, said arms being suitably retained and supported in a pivotal bearing on the standard 17 and being sprin -controlled, .as at 34, so tension is exerted to maintain the cutting edge of the blade against the surface of the paper roll, such parts being preferably substantially the same as are shown in my previous Patent No. 1,116,834, before men tioned. v,

I The roll of paper is retained at its top by a pin, 35, insertibly mounted in the cylindrical socketof the arm 23 of the main standard 17 and projecting downwardly in the top of the bore of the roll. In the two-story unit construction now being described, said re that the spring t-aining pin 35, in the preferred construction.

has. a cylindrical shoulder, 36, at its top, beyond which projects a cylindrical top extension, as at 37, and a disc, 38, constituting a .race track and vcarrying balls, 39, rests upon said shoulder and supports the upper revolving base 40 corresponding to the lower revolving base 26 and likewise having an upwardly-projecting tubular stud, 411 which receives the top extension 37 of the retaining pin 35, the end of said extension being riveted or bit-added over the top of said tubular stud 41, to retain the revolving base 4-0 an d its ball-bearing means in secured relationship. Said upper revolving base and ballbearing construction as just described, constitutes the support for the upper roll of paper carried by the two-story unit. The

intermediate lateral arm 23 of the main standard 17, and the retaining-pin construction for the top of the lower roll of paper, thus constitutes the supporting means for the upper roll of paper and is the base portion or means of the second story of the twostory unit. I c

Intermediateof said arm 23 and revolving-base means 40, and of the top lateral arm 22 of the standard 17, is carried a blade and spring-controlled mounting-arm construction corresponding to that before described with reference to the lower story of the device, which constitutes the cutting means for the roll carried by the second story, said roll being supported upon the upper revolving base with the stud 41 thereof entering the lower end of its bore and with a top retaining pin, e2, insertibly mounted in the cylindrical socket of the top arm 22 and entering the top of the bore of the roll.

The rolls of paper, 81, have a central tubular bore-block, as shown at 4A, and in operation it is desirable to prevent the bore-block of the roll from riding or working up on the retaining pin at the top of the roll when the roll is turning, which action would be liable to throw the roll out of the true centered or axial position which is required to retain the spring-controlled knife blade with its pressure at the same tension throughout the whole vertical length or longitudinalextent of the roll of paper. For this purpose, the cylindrical sockets, designated at 43, at the outer ends of both the

lateral standardarms

22 and 23, are constructed to provide a vertical slot, 45, at the side of the socket. In the preferred construction for this purpose, the socket is constituted by a metallic plate stamped out and formed to produce a. cylindrical body portion and having a substantially T-shaped cross-section with terminal wings, 46l6, which wings are secured to opposite sides of the end of the lateral standard-arm (22 and 23), the slot being formed by the space between the opposite edges of the main cylindrical body portion of said plate. The retaining-pin (42 and 35), which is inserted downwardly in said socket, has a laterally-projecting stud or pin, 47, suitably located at a distance beneath its head, the passage of said lateral stud being permitted by the vertical .slot 45 when the retaining pin is inserted in the socket. In operation the lateral stud 47 of the retaining-pin seats against and projects'over the bore-block 44 of the roll of paper and'operates as a stop to prevent theriding or slipping up action thereof. A corresponding construction of the intermediate retainingpin 35 for the top of the lower roll'of paper is also provided, and the head or top portion of this pin 35, which restsup'on the cylindrical socket 43 at the base of the second story of the two-story unit, is constituted by the race-track disc 88 and revolving base 40 for the upper roll of paper, while the topmost retaining-pin 42 has a laterally-extending head, as at 48, resting upon the top of its cylindrical socket 48. Y

The retaining pins 42 and 35 are preferably of solid metallic-rod construction and of suitable length to extend some distance within the top of the bore of the roll of paper, to brace and position the same, and they thus have considerable weight or gravity action in the bearing of their stopstud 17 upon the bore-block of the roll, which condition of weight is further accentuated in the instance of the retaining-pin by its head construction which constitutes the base portion of the second story of the two-story unit and supports the second-story roll. The counter-balanced statusof the complete cutter, whereby it effects its own counter-balance without occasion for fastening the device in its mounted operative position upon a glass counter or other support, is produced by the determined weight distribution in the general relative assemblage and balance of the two-story units or multiples thereof carrying the rolls of paper as before described, and as an additional element or counter-balance my present improvements comprise a base-weight which consists of a heavy metallic rim-piece, as at 4:9, preferably of lead, which extends circumferentially of the edge of the main stationary horizontal base l t at the under side thereof, said rim-weight member being secured in connection with said base and within a rim-flange, 50, projecting downwardly from the platformbody of said base.

Upon the rear portion of the main horizontal base 14: is preferably provided a twine-holder,.as at 51, which in the instance of a four-multiple cutter is carried by the rear wing-platform 1G, and from said holder the twine, 52, feeds upwardly at the rear of the main standard 17 through guide-eyelets. 53, thereon, in position for convenient use without interference with the paper rolls or the cutting operation thereof.

Under the conditions of construction and relative arrangement of parts as comprised in the improved multiple cutter constituting my present invention, the complete device can be knocked-down. for compactness in transportation, into one part consisting of the main horizontal base 14; and the revolving base or bases which it carries, a part consisting of the two-story unit comprising i the main vertical. standard with the supporting arms and cutting blades and other elements which it carriesnand a part consisting of the retaining-pin 35 and thebase portion of the second-story, construction which it carries, said latter part being detachable from its retaining socket. and said knocked-down parts or members can be thereafter readily and conveniently setup and secured in operative relation in assembling the complete cutter in condition for use. 7 a The operation of the device, and the advantages (of my present improvements, will be readily understood from the tone-going description.

The improved teatures of construction provide not only the essential conditions oi' strength and accurate and eiiiective operation andcounter-balance, but, produce an improved vertical cutter which in compact Shape and dimensions enables the simul taneous employment of multiple rolls of paper in two-story units or a plurality thereof, and which is conveniently portable vand operative upon glass counters or other supports Without fastening in mountedposition.

I do not desire to be understood as limit.- ing myself to the detail constimetion 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 theretore reserve the right to all such variations and modifications as properly fall within the scope of my invention and the terms ofthe ollowing claims.
