V'7 Claims.

This invention relates to that class of devices intended to support rolls of wrapping paper and to mechanism for cutting the paper from the rolls in desired lengths.

An object of the present improvement is to provide a combination support andl cutting mechanism whereby the latter may be adjusted relative to the support so that regardless of the position of the support, whether mounted upon the counter or wall surface, the cutting mechanism may be arranged for proper working-operation.

Another object of the invention is to provide novel cutting means in the form of a bar with the paper so arranged relative thereto that it may be conveniently grasped at any point along its edge for the tearing thereof Without the need of iirst turning the roll so as to advance the paper as is now the common practice with the ordinary type of cutters.

It is also an object of the invention to provide a mechanism of this kind which is extremely simple in its construction, reliable in its operation and one which is comparatively cheap or economical to manufacture.

With these and other objects in view, as will appear as the description proceeds, the invention consists in the novel features of construction, combination of elements and arrangement of parts hereinafter to be fully described and pointed out in the subjoined claims.

Fig. 7 is a vertical longitudinal sectional viewV Referring tothe drawings in detail, numeral 1 designates the paper roll supporting structure in its entirety and comprising the upstanding end members or brackets 2 which are in this instance cast and each formed with a supporting foot 3 for attachment to a counter, wall or the like supporting surface. The lower ends of the brackets may be connected if desired by a bar 4 for the convenient spacing ofthe brackets during the erection thereof to a supporting base and for holding the same connected for shipping or handling purposes.

Carried by the upper or outer ends of the brackets 2 are adapter members 5 which in certain positions of the brackets 2 serve as extensions for the latter and in turn carry at their outer ends the cutting mechanism designated generally by the numeral 6. The adapter members 5 which have been designed particularly for the proper positioning of the cutting mechanism relative to the paper roll, are each formed with a disk like end 7 to conform in shape with the attaching ends of the brackets 2. Passing through the center of the disk 7 is a threaded fastening element or screw 8 which serves to rigidly unite the adapter member to the bracket support 2. It will be noted from reference to the drawings and particularly Figs. 6, 8 and 9, that the adapter members 5 are in each case arranged vertically whereas the brackets 2 may be positioned vertically, inverted or horizontally. This is an important feature in that it enables the paper roll support to be mounted either on top of the counter, its under surface or on a Vertical wall without altering the construction or substituting parts of the support. To hold the members 5 in correct position relative to the brackets 2, the disk like ends 7 are formed with lightly struck-up projections 9 which are received Within similarly shaped depressions 10 formed in the brackets 2. The in` ter-locking relationship of the projections 9 and the depressions 10 also prevent axial rotation of the adapter members 5 with respect to the brackets 2 during the use of the supporting structure.

Provided upon the inner surfaces of the adapter members 5 and locatedat the inner ends thereof are bearingrflanges 11 which are each provided with an arcuate socket 12 for the reception of the shaft 13 passing centrally through the paper roll 14. The sockets 12 are slightly spaced from the members 5 to provide spaces for the enlargements or heads 15 formed with the outer ends of the shaft 13.A 'The heads 15 serve to kprevent longitudinal sliding movement of the shaft and also form connections between the :shaft and the sup- Ydi eil

porting brackets to brace the latter at their upper ends.

The cutting mechanism 6 which is carried by the outer ends of the adapter members 5 comprises a frame including a pair of side arms 16 which have one of their ends provided with fulcrum studs 17 received within bearing openings formed in the outer ends of the members 5. Connecting the other ends of the arms 16 is a cutter bar 18 which in this case is formed of ar strip of sheet metal having a suitable gauge to provide for the necessary rigidity and weight to the cutter frame. Y full length of the roll 14 has its ends provided with down-turned flanges 19 which are attached to the inner surfaces of the arms l6-in any Wellknown manner as, for example, by spot welding the same thereto. Formed with the upper longitudinal edge of the bar 18 is a depending flange 20 which has its lower edge rounded and resting upon the paper roll. The opposite or lower edge 24 of the bar constitutes the cutter and may be turned downwardly or rounded slightly to proteot the hand of the operator and to strengthen the bar at this point. The rounding of the bar is however not essential from a cutting standpoint, as the edge may be straight and serve equally as well.

Arranged below the top wall of the bar 18 and located near the upper edge thereof is a pair of rods 21 and `22 respectively over which the paper 23 is trained to take a somewhat tortuous path with the rod 22 acting to holdthe free edge of the paper spaced from the cutting edge. This spacing of the paper from the cutting edge provides for the convenient grasping of the paper and enables the operator to take hold of the paper at any point throughout the Width thereof. If desired, the bar 21 may be made removable to facilitate the insertion or training of the paper between the rods.

To effect this removal of the bar, a pivoted spring finger 25 is provided which is located exteriorly of one of the arms 16 and has its free end formed with a slight depression entering one of the bearing openings formed in the arms for the rod. By swinging the finger 25 to one side, the rod may be pulled outwardly so as to free its ends from engagement with the bearings, as will be readily understood.

In operation, it will be seen that as the operator grasps the free end of the paper and exerts an outward pull thereon, the paper will pass under the lower edge of the ange 20, over the rod 21 and under the rod 22 until the desired length of paper has been unwound at which time the paper is brought into engagement with the cutting edge and cut in the ordinary manner. After the cutting operation, the paper edge will drop down to a position shown particularly in Fig. 2 which is due to the arrangement of the rod 22 and the tendency of the paper to straighten out. Due to the character of the paper which is somewhat stiff, the same will hold itself in engagement with the rod 22 and the free end thereof held in an elevated position but yet spaced from the cutting edge of the bar. The ange 20 under which the paper is passed serves as a brake for the roll, and prevents the paper from sliding back and becoming disengaged from its connection with the cutter bar.

From the foregoing it will be seen that a novel support for a roll of wrapping paper and a, cutting mechanism for the paper thereofY has beenprovided which has several outstanding advantages in The bar 18 which extendsthe` that due to the construction thereof, the paper roll may be mounted on various supporting surfaces such as on top of a counter, the under side thereof or upon a vertical wall and yet maintain the cutting mechanism in its proper relation thereto. The cutting mechanism thereof also has the advantage of being efficient in its operation and will permit the ready grasping of the paper edge without the necessity of first turning the roll so as to advance the paper as has to be done with paper cutters of ordinary construction. Due to the particular arrangement of the paper relative to the cutter bar, the paper is spaced from said bar throughout the full length thereof so that the paper may be grasped at any point of its Width thereby greatly facilitating the paper cutting operation.
