PAPER-ROLL HOLDER.

Application filed January 29, 1919.

To all whom it may concern:

Be it known that I, TrioMAs M. HOUSE, a citizen of the United States, residing at Richmond, in'the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Paper-Roll Holders, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to devices for supporting rolls of paper in such position that the paper may be readily unrolled and cut off in convenient lengths, and particularly to a device of this character wherein the roll of paper is supported in a vertical position.

The general object of this invention is to provide a structure of this character which shall require a relatively small amount of material for its construction and which shall be correspondingly cheaper than devices heretofore used for this purpose.

A further object is to provide a cutting blade which is operatively supported at one end upon the roll spindle and at its other end operatively supported upon the base whereby to do away with the necessity of using a separate vertical support for the cutter blade and eliminating the consequent cost of this support.

A further object is to provide improved means for mounting the cutter blade so that when the cutter blade is detached from its operative connection at its upper end with the spindle, it may be turned away from the spindle and entirely out of the Way of the roll so that the roll may be readily removed and replaced.

A further object is to provide improved means for maintaining an operative connection between the upper end of the cutter blade and the spindle and locking the cutter blade in its vertical position, said means being so constructed as to take up wear and slack and preventing any rattling of the arts or loose joints.

Still another object is to provide 1mproved means for resiliently urging the cutter blade toward the roll of paper.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of a paper Specification of Letters Patent.

Serial No. 273,819.

roll holder constructed in accordance with my invention;

Fig. 2 is a top )lan view of the upper portion of the holder showing the locking and blade tensioning device in operative position; V

Fig. 3 is a like view to Fig. 2, but showing the locking and blade tensioning device thrown out of operative position;

' Fig. 4 is a section on the line of Fig. 1 with a portion of the disk 19 broken away;

Fig. 5 is a side elevation, partly in section, of the paper roll holder showing the cutting knife turned to a horizontal position to permit the replacement of a roll upon the spindle; and

Fig. 6 is a sectional view through this spindle and looking down upon the hub 12 and pin 15.

Referring to these drawings, it will be seen that the base 10, which is preferably made of cast metal, but may be constructed in any suitable manner, has an opening 11 at its center and that attached to the center of the base in any suitable manner or formed therewith, is an upstanding hub 12. The margin of the base is downwardly turned or flanged, as at 13, and the base is provided with apertures for the passage of screws, whereby the base may be held upon a counter or other support.

Extending upward from the base is a spindle 14 which, at its lower end, is screwthreaded and is provided with a transversely extending pin 15 which rests in notches 16 formed in the hub 12. Engaging the lower end of the spindle 1 L is the nut 17 which bears against the under side of the base 10 and holds the pin 15 seated, but permits the spindle to be readily disengaged from the base when desired.

Loosely surrounding the spindle 14. is a tapered centering collar 18, to which is attached the disk 19. The roll of paper A rests upon this disk, with the spindle 1 extending through the core a. of the roll. At its upper end, the spindle 14' is cut away at 20 to provide a centrally disposed, up-

wardly extending lug 21, which is notched, as at 22, the opposite upper and lower faces of the'notch being convergently disposed.

As illustrated, the base 10 formed at one point with a boss 23 adjacent the margin of the base, and pivoted upon the upper face of this boss is a lever 24, the inner end of which is connected to a coiled contractile spring 25, which extends across the upper face of the base and is, at its end, connected to a stud or pin 26. The outer'end of the lever 24'is formed to provide two ears 27 and coacting with these ears is an arm 28 which is angularly bent, as at 29, the down wardly extending portion of this arm having at its end a hinge bead 3O coacting with the ears 27 and through which a pintle 31 passes, this pintle being in the form of a bolt so that it may be removed. It will be noted that the metallic strip forming the arm 28 is twisted in its length at 32 so that the greater portion of this arm is disposed in a vertical plane, thus securing full strength for the metal strip and rendering it easy to attach the strip to the cutter blade 33.

To the upper end of the cutter blade3 is attached an arm 34 which, at its outer end, is pivotally .connected by a pivot 35 to a supporting member or bracket 36. This consists of a fiat strip of metal which, at its ends opposite the pivot 35, is formed to pro vide an inwardly extending slot 37 having a depth -greater than the depth of the lug 21, the opposite walls of the slot at their inner ends being parallel and spaced a distance just sufficient to receive the lug 21, while these walls at their outer ends are divergently related. Pivoted to the slotted end of the bracket 36 beyond the inner end of the slot 37, is a locking arm 38 which rests upon the upper face of the bracket 36 and which, when this bracket is in place, extends into the notch 22, as illustrated in Fig. 2, and binds against the convergently beveled walls of the notch. The outer end of this arm 38 is engaged by a coiled contractile spring 39'whose other end is engaged with apin or stud 40 on the arm 34. This spring 39, therefore, urges the arm 38 into its engagement with the notch 22 so as to lock the bracket 36 firmly upon the upper end of the spindle 14 and also acts with the spring 25 to urge the blade 33 against theroll of paper.

The blade 33 as illustrated in Fig. 2, is made of a strip of sheet metal bent to form a longitudinally extending bead 40 intermediate the edges of the strip, and to provide a fiat portion 41 and a depending flange 42. This flat portion 41bears flat against the

arms

28 and 34, the flange 42 being notched to permit the passage of these arms and the blade is held to the arms by rivets, screws, or other suitable fastening devices 43.

In the use of this device, the roll of paper is placed upon the spindle 14 and rests upon the rotatable disk 19. The paper A is wounduipon a core a which is formed with a longitudinally extending passage, this being the usual construction of these paper rolls (though more than one core may be used), and a centering bushing 44 having a tapered hub is disposed in the upper end of this bore, this bushing fitting loosely upon the spindle 14. i The lower end ofthe core a rests upon the tapered bushing 18 which forms. the hub of the disk 14. In order to put the paper roll in place, the arm 38 is turned from its locking position in the direction of the arrow in Fig. 2 to a position whereit extends in an opposite direction to its former position. Then the bracket may be slipped from its engagement with the spindle 14 by tilting the blade 33.- This tilting movement is permitted by the hinged .joint of the arm 28 with the lever 24. This joint permits the blade to be tilted entirely away from the spindle 14 and to a depending position if desired, or to a horizontal position, depending upon where the device is mounted. After the roll of paper is disposed upon the spindle, the bushing 44 is placed upon the spindle with its tapered hub within the upper end of the core and then the knife or cutter 33 is brought back to its Vertical position so that its edge bears against the paper and the slotted end of the bracket 36 is shifted into position to engage the lug 21 and the locking bar 38 is shifted into engagement with the notch 22 in the manner heretofore described. Under these circumstances, the

springs

25 and 39 will act to urge the cutter or blade 33 into contact with the paper. The device is then all ready for use.

It will be seen that a construction of this kind may be relatively cheaply made because of the fact that it has but few parts, and that no separate rod orstandard is used for supporting the arms carrying the cutter 33. It will likewise be seen that my construction permits the cutter to be readily shifted from its operative position to a position entirely out of the way where it will not in any manner interfere with the removal of an old core from the spindle or the replacement thereof by a new roll.

While I have heretofore described this device as being vertical, yet it will be understood that the spindle might be disposed in a horizontal plane. It is to be noted that all of the parts of this device are readily disassembled so as to permit the device to be compactly arranged for packing and transportation. Thus, for instance, the spindle 14 may be easily detached from the base and the arm 28 detached from the lever 24 by permits the ready disassembling of the parts, it also permits the easy assembling of them.

I have found this device to be particularly effective in practice, and while I have illustrated an embodiment of my invention which I believe to be particularly good and economical in construction, it is obvious that the details of construction and arrangements of parts might be varied in many respects without departing from the spirit of the invention as embodied in the appended claims.
