Patented Feb. 14, 1933 UNITED STATES PATENT OFFICE 'FRANK E. PFEIFFER AND WILLIAM C. PFEIFER, OF DAYTON, OHIO, ASSIGNORS TO THE EGRY REGISTER COMPANY, OFKDAYTON, OHIO, A CORPOEATIGN F OHIO WEB ROLL SUPPORTING DEVICE Original application filed February 19, 1930, Serial No. 429,584. Divided and this application led February 24, 1931.

Y T his invent? on relates to a paper roll supporting device, and has for its object to provide, in connection with an autographic register or other duplicating machine, means for f supporting a roll of paper so that the sheets tion. p Figure 2 is a section on the line 2-2 of of paper may be fed therefrom in a regular, orderly and systematic manner.

It is the object of this invention to provide an inclined support for the axle carrying a roll of paper and a support on this in- Cline, and to provide means on this incline for These and other advantages will appear' from the following description taken in con- S nection with the drawing, in which is shown a preferred embodiment of .this invention.

This application is a division of application Ser. No. 429,584, filed February 19, 1930.

Referring to the drawing:

Figure 1 is a section through a casing showing the roll supporting device in eleva- Figure 1.

Figure 3 is a top plan view of one of the rails showing the sliding hook plate.

The web supporting device is as a whole inclosed in a. casing having a bottoni 1, side walls 2. a front wall 3 and a rear wall 4. In the casing thus formed there is a paper supply roll 5, which has extending therethrough an axle 6 for supporting the roll in a rotating condition.

For supporting the axle and the paper roll thereon there is a pair of rails 7, each having a notch 8 nearer the upper end than the lower end. Each rail 1s 1n thelform of an angle iron, and in addition to the vertical part has a lateral extension or portion 9.'

0n this lateral extension is a slide plate 10,

Serial No. 517,683.

which has one or more slots 11 therein for receiving studs 12 in the lateral portion of the rail 7. On the lower end of each sliding plate is a hand piece 13 to be gripped for moving the sliding plate along the lateral portion of the rail. At the end of the sliding plate, opposite the hand piece, is a hook 14 adapted to fit over the end of the axle and hold it in the notch or slot 8. The hook is shown in engagement with the axle in Figure 1, and tends to hold the axle in the notch 8. riihese two rails are held together by means of a lower cross rod 15 and an upper cross rod 16. rlhese two rods and the rails form a rectangular frame for supporting the roll and its axle. supported in the walls of the casing.

Whenever it is desired to place the roll upon the rails, the roll is placed between the two rails with the, ends of the axle resting upon the rails. The axle is caused to move up the rail and todrop into the notches 8. l/Vhen the axle has been properly seated the hooks are caused to lit over the ends of the axle so ,it is held in position. 1n order to prevent a too free rotation of the roll'of paper, there is pivoted to the cross rod 16 a pair of arms 17, which are connected by a cross rod 18. Between the free ends of the arms 17 is a roller 19 supported yby a roller shaft'20.

The roller 19 bears against the periphery of the paper roll so that a too free rotation is prevented and the strips of paper are held ktogether until they leave the rollers 19.

rfhere is a plurality of superimposed'strips of paper adapted to be fed 'all at-the saine time and at the same rate of speed. These strips of paper, with the except-ion ofv one strip, are indicated by the numeral 21. "In the 'presentinstance there are seven of these strips indicated by the numeral 21. Another strip, indicated by the numeral 22, is separated from the strips 21 as they leave the roller 19. This strip 22 passes over a guide roller 28 beneath a feed roller 23, and over a second feed roller 24. The feed roller 23 has a gear 25 thereon meshing with a gear 26 on the feed roller 24 so that these two rollersrotate in unison and tend to positively feed the sheet of paper passing between them. These The cross rods 15 and 16 are rollers are positively driven by means of a driving gear 27, suitably connected to some source of power and engaging with the gear 26. The roller 28 is merely a guide roller to hold the' paper i-n Contact with the roller 23 so dthat the sheets of paper will be positively fe These rollers are supported by the side walls of the casing and by plates 29, one for each wall. One end of each plate is supported in a side wall by means of the spindle part on the end of the roller 28%. The end of the plate Lopposite the Aroller 28 has attached thereto a pin 30, which extends through a bracket 3l attached to the side wall. Un this pin adjacent the bracket 3l is a spring 32, held thereon and tensioned by means of a nut 33. On the ends of the roller 23 there are cam means which cooperate with slots in vthe plate 29 for moving 'the rollers 23 and 24 apart so that the sheet of paper may be fed between them. y

The source of power :tor operating an autographic register, or other duplicating machine with which this apparatus is used, causes the rollers 23 and 24C to rotate, and since the sheet of paper 22 passes between theselrollers a rotation of the rollers will cause-the roll l5 to rotate to feed oil the sheets of paper. The speed at which the feeding of the paper takesplace may be determined vby the sizes of the rollers`23 and 24, or by the relative dimensions of the gear connections between the autographic register operating means and the rollers 23 and 24.

"We desire to comprehend within our linvention such modications as maybe embraced within our claims andthe scope of our invention.

fHaving thus fully described our invention,

Awhat we claim as new and desire to secure by Letters Patent, is

l. In combination, a pair of spaced roll axle supportshaving axle notches therein, hooks slidablev beneath the axle and engaging over-the axle for locking said axle in said notches, a-.pivoted weight mountedA on said yaxle supports, and means VJfor positioning said weight at a. predetermined position with respect tosaid roll.

2. ln combination, a pair of spaced roll axle supports having axle notches therein, means consisting of sliding hooks located beneath the axle for locking said axle in said notches, a pivoted weightl mounted on said axle supports, and means for positioning said weight with-respect to the axle ofthe roll and its support so that the weight will not only resist the unrolling of the roll but serve to maintain the axle in' its-support.

3. In combination, apair of rails, each having `ai notch therein, a roll having an axle adapted to rest in said notches, a sliding hook on1 eachrail adapted to pass under, around one side and the top of the axle to cooperate with the notches in holding the axle, a pair of arms, each pivotally supported at one end by the rails, and a brake roller at the other enlcls of the arms and adapted to rest upon the ro` 4. In combination, a frame composed of side rails and end rods, each side rail having a notch therein, a roll having an axle adapted to rest in said notches, a sliding hook on each rail beneath the axle to engage the axle inthe notch on its bottom, one side and top, and a swinging brake member on ione-end rod adapted to restupon said roll.

5. ln combination, a frame composed of side rails and end rods, said siderails being formed of langle irons having a lateral portion and a vertical portion,each vertical portion having a notch therein, a sliding hook member on each lateral portion adjacentthe notch in the vertical portion, a roll having anaxl'e adapted to restin the notches and be engaged by'thehook members, a pair of swinging arms, each attached at one end to an end rod, and a brake roller yon vthe other ends of said arms and adapted to rest vpoint of departure of said sheets, thereinainder of said sheets beingallowed to loosely unroll.

In testimony whereof, we aiiix our signatures.
