Specification of Letters Patent.
Patented Feb. 6, 1912.
Application filed March 20, 1911. $eria1 No. 615,589.
To all whom it may concern:
'Be it known that I, ALBERT W. Jonnson, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Paper-Holders, of which the following is a specification, the principle of the invention beingherein eX- plained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.
The present invention relates to paper holders, and its general object is the provision of mechanism whereby a predetermined length of paper may be removed from a concealed supply, and whereby the removal of more than the predetermined amount is prevented.
To the accomplishment of these and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.
The annexed drawing and the following description set forth in detail certain mechanism embodying my invention, such disclosed means constituting, however, but one of the various mechanical 7 forms in which the principle of the invention may be used.
In said annexed drawings afiigure 1 is a vertical section of a holder embodying the present invention; Fig. 2 is a section on the same plane as Fig. 1, but partly broken away and showing certain parts in difierent operative position than in Fig. 1, and Fig. 3 is a vertical section partly broken away on the line A-A in Fig. 1, the line B-B in Fig. 3 indicating the plane of the sections shown in Figs. 1 and 2.
The holder comprises a casing 1, the front partof which is removable in order that access may be had to the interior of the casing, the preferable construction being to pivot the front portion to the rear portion as at 23. The casing is also provided with a slot 2. Within. the casing is removably held a roller 3 on retainers 4 provided on.
the opposite walls of the casing, and on the roller 3 is a stock of paper 5. The stock, removal of which is to be controlledby the mechanism, is referred to throughout as paper, but obviously it may be any other desired material, and furthermore, the stock need not be in the form of a roll, but may be in any other form which will lend itself to withdrawal of the stock.
and the roller 21. V
of the parts, the pawl 12 is in engagement A rotatable shaft 6 is journaled in the opposite walls of the casing 1 and is provided exteriorly of the casing with a handle 7. A roller 8, provided with a friction surface 9,is mounted loosely on the shaft 6 within the casing, and to the end of the roller 8 is rigidly secured a disk 10 which is provided in its periphery with a notch 11. A pawl 12 is pivoted to the casing and is pressed against the periphery of disk 10 by a spring 13, the pawl being formed to engage the notch 11 when the disk is in proper relation to the pawl. A. collar 14 is fixed on the shaft 6,.
and it bears an arm 15 adapted, on rotation of the shaft, to lift the pawl 12 from the notch 11. A spring 16 is secured at 17 to the disk 10, and at 18 to the arm 15 and tends to restrain the arm from rotation in a clockwise direction. The counter-clockwise movement. of the arm 15, however, is limited by a pin 19 on the disk 10, and likewise, its movement, in a clockwise direction relatively to the disk 10, is limited by a pin 20. A second roller 21 is supported from the casing 1 by springs 22 and bears against the friction surface 9 of the roller 8.
In operation, a stock of )aper or other material will be placedwit in the casing and v the material will be drawn down between the friction surface of the roller 8 In the normal position with the notch 11 of the disk 10, and hence rotation of the roller 8, to which. the disk is secured, is prevented. This, in turn, prevents stock' from being removed from the casing, even though it may extend out through the slot 2, for the stock cannot be drawn over the friction surface ofthe roller 8 against which it is pressed. A slightrotation of the handle 7, however, rotates the arm 15 against tension of the spring 16 .until the arm lifts the pawl from the notch in the disk, as shown in Fig. 2. The friction roller will be rotated slightly as soon as the pawl is lifted from the notch by the tension of the spring 16, and after continued use, during which the spring 16 may weaken, the 7 arm will efi'ect this rotation of the roller by engagement with the pin 20. The pawl having been lifted from the notch in the ther rotation of the roller is thereby pre- 1 'the disk again comes into register with the pawl which is pressed into the notch. Furvented, and consequently, further withdrawal of stock is prevented, and the stock already withdrawn may be removed by pulling it against the sharp edge 24 formed along one wall of the slot 2. It is therefore obvious that withdrawal of stock is allowed only "upon rotation of the friction roller, and that by placing the notch in the disk in the proper place or places only a predetermined portion of a revolution may be allowed to the roller 8, and hence only the predeters mined amount of stock may be withdrawn at one time. It is preferable, from the standpoint of construction, to form the notch in a disk and to fix that disk to the friction roller, but obviously, the principle or mode of operation will be unchanged if the notch be formed directly in the periphery of the roller itself, and other changes may be made in the mechanism without altering the mode of operation, such, for instance, as the form of the supply of stock. Nevertheless, this supply will ordinarily be in the form of a roll, for by means of the governing mechanism of the present invention, no special preparationv of the stock to suit the mechanism is required, and the stock need not even, and indeed should not be, perforated, and consequently, the holder may be much more'economically supplied with stock.
Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
I therefore particularly point out and distinctly claim as my invention 1. In a device of the character described,
' the combination of a suitable support, a
roller secured thereto, a disk secured to said roller and provided with a notch in its periphery, a pawl normally engaging said notch, an arm adapted, on movement, to disengage said pawl from said notch, and means connecting said arm and said disk and adapted, upon disengagement of said pawl from said notch, to impart a rotative movement tosaid roller. 1 2. In a device of the character described, the combination of a casing, a roller secured therein, a disk secured to said roller and provided with a notch in its periphery, a pawl normally engaging said notch, an arm adapted, on movement, to disengage said pawl from said notch, means connecting said arm andsaid disk and adapted, upon disengagement of said pawl from said notch, to impart a rotative movement to said roller, and means outside of the casing for moving said arm.
3. In a device of the character described, the combination of a casing, a rotatable shaft journaled therein and provided with a handle exteriorly of the casing, a roller loose on said shaft, a disk fixed to said roller and'provided with a notch in its periphery,
a pawl bearing on the periphery of said disk and adapted to engage said notch, an arm secured to said shaft and adapted to lift said pawl from said'notch, and a spring secured to said arm and to said disk.
. 4. In a device of the character described the combination of a casing, a rotatable shaft journaled therein and provided with a handle exteriorly of the casing, a first roller loose on said shaft and having a friction surface, a second roller bearing against the c first roller, a disk fixed to said first roller and provided with a notch in its periphery, a pawl bearing on the periphery of said disk and adapted to engage said notch, an arm secured to said shaft and adapted to lift said pawl from said notch, and a spring secured to said arm and to said disk.
