This invention is concerned with a paper roll holder, it being a general object of the invention to provide a paper roll holder of simple, effective, improved construction and operable to carry a roll of paper in a most convenient and advantageous manner and so that paper can be used from or withdrawn and severed as required for use.

The structure of the present invention involves a frame formed of spaced vertical standards which are of box-like construction and a head which extends between and is fixed to the upper ends of the standards. The invention provides a simplified, inexpensive, sturdy standard construction and provides a dependable secure means of joining the head of the frame to the standards. A roll mounting is carried beneath the head and between the standards and involves, primarily, a rod, the ends of which are engaged in upwardly opening sockets in the standards, openings and guideways being provided for convenient passage of the rod into and out of operating position. A cutter or roll holder is provided and involves arms, one at each standard, means in the form of a hook construction pivotally coupling each arm to its supporting standard, a blade extending between the outer ends of the arms and means coupling the ends of the blade to the ends of the arms so that these parts are permanently joined for limited movement or flexibility of the blade relative to the arms. A means is provided for operating the cutter, which means involves a leaf spring in each standard having its lower end anchored through a simplified, effective construction while its upper end bears against the arm pivoted to the standard, there being an abutment intermediate the end portions of the spring over which the spring is flexed, the abutment being adjustable from the exterior of the standard.

It is a general object of this invention to provide a construction of the general character referred towhich involves few simple easily formed parts which cooperate to establish a slightly sturdy practical mechanism and which are such that they can be assembled in a most convenient manner.

Another object of the invention is to provide a simplified, practical frame construction for a device of the character referred to. The frame provided by the present invention is formed entirely of light or thin sheet metal, the formation and relationship of parts being such that the frame thereof formed of light metal is rigid and sturdy and is of neat smooth appearance.

4 Claims. (01. 242-555) A further object of the invention is to provide a simplified unique construction relating the paper cutter to the frame through which construction the arms of the cutter are latched or hooked to the frame and when thus engaged with the frame are acted upon by the springs carried by the standards of the frame so that the arms are individually operated in the desired manner.

The various objects and features of my invention will be fully understood from the following detailed description of a typical preferred form and application of the invention, throughout which description reference is made to the accompanying drawings, in which:

The construction provided by this invention is intended primarily to rotatably support a roll A of paper, or the like, and is such that it can be used to advantage on a counter or other suitable stand or support, this type of device being of the character employed in stores and various industrial or commercial establishments where spring G and an adjustable abutment H engaged by the spring and governing the action thereof.

The standards B are spaced vertically disposed elements or units preferably formed of sheet metal, and since they are alike I will describe one, it being understood that such description is applicable to both.

Standard B in accordance with the present invention is characterized by a flat vertically disposed outer wall IO, inwardly projecting front and rear edge walls II and I2, a base I3, top I4, and an inner wall I5 spaced inwardly from the wall I so that a chamber I is established in the standard.

The outer wall I0, edge walls II and I2, base I3 and top l4 are preferably formed as a single or integral unit, in which case the edge walls I I and I2 are in the nature of flange-like projections that extend inwardly from the vertical edges of the outer wall III while the base II extends horizontally and inward from the bottom edge of wall I 0 and the top I4 extends horizontally from the upper edge of wall I0. In the preferred construction the upwardly extending or vertical edges of the wall II] are not truly vertical, but converge somewhat so that the standard is upwardly convergent or tapered, as shown throughout the drawings.

The inner wall I5 is preferably a substantially flat plate-like part that depends from the edge I8 of top I4 and extends between the edges I9 01" the edge walls II and I2.

In accordance with the present invention the inner wall I I is rigidly fixed to or is joined with the unit which includes the outer wall I0, and in the case illustrated it has a bottom 20 that extends between its lower end and the wall It and adjacent the inner side of wall I0 it has a depending flange 22. Ears 23 are struck from the wall II) as by punching, so that they are upwardly faced and are spaced inward from wall In so that the flange 22 is received between them and the wall II in the manner illustrated in Fig. 3. Near the upper end portion of the standard two horizontally spaced pins 30 and 3I extend between and connect the walls In and I5. In the case illustrated the pins 30 and 3I are riveted to wall I5, as at 32 and 33, respectively, while their outer ends are releasably fastened to wall In by suitable screw fasteners 34.

The head C is an elongate horizontally disposed element formed of sheet metal and in its preferred form it has a fiat top 35 and depending sides 36. The ends of the head C are joined to the upper ends of the standards B so hat the top 35 adjoins and is flush with the tops I4 of the standards while the sides 36 of the head are flush with and adjoin the edges I0 and I I of the standards. In the form of the invention illustrated the upper ends of the standards are permanently joined to the ends of the head C and in the case illustrated the desired connection is provided by establishing a flange 31 on the upper end of wall I5 to engage under the top 35 of the head and by establishing flanges 38 on the wall I5 to engage inside the sides 36. The flanges 31 and 38 are preferably secured to the head C as by welding.

In the preferred form of the invention the frame further includes a stretcher 40 which extends between the bases of the standards. In the case illustrated each base has an upwardly projecting part 4i forming an abutment to be engaged by the spreader 40 and ears 42 are struck from the bases adjacent the abutments M and overlie the end portions of the spreader 40 and serve to connect the spreader to the bases with the ends of the spreader in engagement with the abutments M. In the preferred form of the invention the spreader 40 is ribbed so that it may be light and at the same time rigid. When a ribbed construction is employed the ears 42 may be shaped to engage around the ribbed spreader construction as clearly shown in Figs. 2 and 10 of the drawings.

The roller mounting D preferably involves an elongate bar or rod adapted to be engaged through the core elements 44 of the roll A. The rod is of such length that its ends project somewhat beyond the ends of the roll A and the structure is such that the roll A fits between the standards Bwith suitable clearance while the ends of the rod D are engaged with or supported by the standards. In the preferred construction the front edge wall II of each standard is cut away to form an opening at 46 and the inner wall I5 has a guideway 41 formed in it, extending inwardly from the opening 46 and terminating at an upwardly facing notch or socket 48. The sockets 48 in the walls I5 of the two standards receive the end portions of the rod that carries the roll A so that the roll is effectively supported for rotation between the standards. In the particular case illustrated the rod 49 is a simple straight tubular element in the form of a length of pipe, or the like.

The arms E are related to the standard so that there is one arm carried by such standard. Each arm in accordance with the preferred form of the invention is an elongate sheet-metal part with a body portion 50 and an inwardly projecting marginal flange 5| which makes the arm somewhat cup-shaped or cup-like and which materially stiffens the arm.

The means provided for pivotally coupling or connecting arm E with its supporting standard B preferably utilizes pin 30 which connects walls I0 and I5 and which is spaced inward somewhat from the front edge wall II. The arm E has a notch 53 extending into it from its upper edge and in the preferred construction the notch extends inwardly and rearwardly in the arm establishing a hook-like part 54 engageable around the pin 30 in the manner illustrated in Fig. 6 of the drawings. The notch 53 is spaced somewhat from the inner end 56 of the arm so that the arm has an inner end portion 51 that receives the pin and has an outer end portion which opens at an edge of the arm such as the foremost edge of the arm. The arm projects forward through a notch or opening 60 in the front edge wall II of the standard. Through the construction just described the arm E can be easily inserted into the cavity or chamber I6 of the standard and there manipulated so that the part 54 hooks around the pin 39 so that the pin is received in the notch 53. In the preferred construction the pin has a reduced portion 6| on which the arm is hooked or carried so that the arm is held adjacent the wall I5 of the standard.

The blade F may vary in form and construction. However, it is preferably a simple, elongate strip that may be shaped or ribbed as shown in Fig. 2 of the drawings so that it is rigid and has parts which bear on the roll A while an edge 65 is presented over which the paper can be torn orby which the paper is cut in the manner similar to structures of this general character.

In accordance with the preferred form of the invention'each end of the blade F is attached to an arm E to have limited pivotal movement and so that it'can vary somewhat as to angle or pitch relative to the arm, as circumstances may require. In accordance with the present inventicn'the connection at each end of the blade involves a tab-like extension projecting from or beyond the end of the blade and entering an opening or hole H in the body 50 of the arm. The extension 10 is preferably an integral part of or continuation of the blade and the opening H is preferably a round opening or bore which receives the extension 10 so that the blade can turn about an axis concentric with the opening 1|. :A laterally extending part or retainer 12 is provided on the outer end of extension 10 or beyond the outer side or body 50 of the arm and is of such extent as to positively prevent displacement of the extension 10 from the opening H. In accordance with the present invention the end portion of the blade enters between the cup-like construction of the arm and the blade engages or cooperates with the fianges 5| of the arm to limit the pivotal movement of the 'arm.

out of synchronism with the other.

The spring G carried by each standard is preferably an elongate spring element or unit and it may, as shown in the drawings, be formed of a plurality of leaves or separate parts so that it has the desired strength and at the same time has suitable flexibility. In the case illustrated the spring G is of laminated construction and it extends upwardly from a point adjacent the bottom of wall I5 to a point somewhat above and between the pins and 3|. of the spring is anchored in the chamber H5 or to the standard. In the case illustrated an inward projection 80 is provided on wall [5 and enters a notch 8| in the edge of the spring near its lower end. The engagement of the projection in the The lower end notch 8| holds the spring down and the disposition of the spring in the structure, as will appear from the drawings, causes it to tend to bear forward at its lower end, which action of the spring is checked by a stop 82 in the form of a lug struck upwardly from the bottom 20, as shown in Figs. 4 and l'l of the drawings.

The spring abutment H engages the intermediate portion of the spring and is preferably so adjusted that the upper end portion of the spring that occurs between the pins 30 and 3! tends to move forward or toward the front edge wall II. The arrangement and relationship of parts is such that the forwardly pressing upper end portion of the spring G engages the inner end portion 51 of the arm. In the preferred construction an anti-friction roller 85 is carried on the arm portion 5! by means of a pivot pin 86 and the spring bears on or engages the roller.

The spring abutment H is preferably in the form of a screw horizontally disposed in the chamber I6 to engage the middle portion of the spring G. The screw is guided or carried by inwardly struck lugs 87 and 88 that project from wall l5 and it may be threaded through one of the lugs as, for instance, through lug '88. The screw 89 projects from the standard through a suitable opening 90 in the rear edge wall I2 and is provided at its outer or projecting end with a handle 9| by which it can be conveniently rotated or operated.

From the foregoing description it will be apparent that the frame with the standards B assembled with the head 0 and with the springs G in thestandards and engaged by the adjusting screws H may be constructed or assembled and may be readily shipped or handled with the arms E detached, the arms being coupled to the ends of the. blade F through the construction above described. .When the structure is ready for use the inner end portions 5'! of the arms may be inserted in the chambers 16 of the standards against the forward pressure of the springs G and when the arms have been hooked to the pins 30 the structure is ready for use. To insert the roll A in the structure it is preferred that the arms be swung up to a position such as is indicated in dotted lines in Fig. 2, in which case the action of the springs against the end portions 51 of the arms holds the arms in the up position. When the roll has been arranged in place the arms can be swung down or to a position such as is shown in full lines in Fig. 2, in which case the springs acton the inner end portions of the arms to cause the long or outer end portions of the arms to bear downwardly and thus hold the blade F in the desired pressure engagement with the rollA. Asthe structure is operated the blade maintains desired pressure engagement with the roll and as paperis used from the roll the blade will follow the roll until the paper is entirely consumed.
