Application filed April 1'-, 1909. Serial No. 487,215.

To' all whom: it may concern:

Be it known that I, HENRY M. GRIFFIN,- a citizen of the United States, residing in the city and county of San Francisco' and State of California, have invented new and useful Improvements in Paper-WVinding Devices, of which the following isa specification. a

This invention relatesto paper holders and winders. 7

Among the several objects of my inverr' tion, one purpose is to provide a simple,

strong and easily operated apparatus to support large rolls of paper sothat it may be drawn or unwound with great facility. I also provide means whereby rolls of paper which have become deformed or; creased may be rewound in perfect order,.'and provide in combination, means whereby a roll of paper may be accurately adjusted with relation to the point of delivery of the paper as it is unwound from the roll.

The invention consists of the parts andthe construction and combination of parts as hereinafter 'morefully described and claimed, having reference to the accompanying drawings,- in' which Figure 1 is an end View of the roll ca-rriage, with the frame in section. Fig. 2'is a side elevation of the apparatus. Fig. 3 illustrates across section of the frame showing the paper 'roll and brackets in a tilted Fig. 4 is a detail partly in sectionshowing aportion of the shaft 18 with its pulley 20.

In the present embodiment of my invention, I have provideda main supporting frameA having suitable upright ends 2 provided with the front and back bearings 3 and 4 for the rods 5 and- 6' which exltiendods provided with bosses 9 adjustably securedtothe rod 5by suitable devices, such as the setscrews '10. The rear legs of the brackets 7 and 8 slidably rest upon: the bar 6 which is firmly 'held inthe bearings 3 A suitable truss or tie-rod 11- connects the rear legs ofthe brackets 7 and 8- to properly reinforce and space them and cause themto move in unison. The bracket 7 is providedat its ufpper end with a' screw-threaded bearing 12 t rough-which may be turneda screw 13 by means of a suitable hand-wheel I l. The inner endofthe screw 13 is provided with a adapted to' be inserted into the center core of a rol of paper,- such as indicated at I6, the opposite end of the roll being supported upon a center 17 which is preferably pyramidal, soas to' tightly engage the opposite end of the core in the roll, though the center be a plain cone, if desired. This tapered center 17 is here shown as being securely fastened to a short shaft 18" turnable in a removable sleeve 19- mounted in the box at the top of the bracket '8. The outer end of the shaft 18- has splin'edupon it a suitable pulley 20 heldina guide bracket 21. Thus when a roll of'paper hasbeen mounted upon the centers 1 5 and 17,-. the center 15 having been suitably adjustedby means of the screw 13, then the roll of paper may be freely revolved, so that the paper may be unwound; the screw 13 being held; fromtu-rnin-g by means of a suitable clamp lever 22, and screw 23'- Which is fastened in the bearing12;

For the purpose of shifting the roll'lengthwise of the main frame A, so as to adapt it to the rewindi-ng machine, I have provid'ed a screw 24: mounted toturn in the bracket 21. The screw 24 has fastened upon it a collar 25 which is engaged upon each side by the yoke 26' of alever 27 fulcrumed at 28 upon the bracket 21-. The lower end of the lever 27 is engaged by a flanged collar 29 secured upon the transverse rod 5, consequently when the'screw is turned by its handle 24?, the lever 27 willfibe oscillated, causing the-rod 5 tobe reciprocated transversely through its boxes 4, and carrying the brackets 7 a-nd 8 and the supported" roll of-paper 16 into the required position.

When it is desired to wind or rewind a roll ofpaper upon a hollow wooden core or sleeve, the driving center 17- may be provided with suitable corrugations 30 or other ;means whichwill positively engage the end of the sleeve'upon which the paper is tobe iwound. Power is applied to -the pulley 20, so that the cente'r'1'7- will be driven, thereby tl1ereonto.- The other pintle 15 turns loose on the end of the screw shaft 13: If a roll '16 is inserted between the centers 15 and protected by wooden or other cores, become revolving the sleeve and winding the paper loosely mounted conical center or pint-1e 15 flattened or mutilated so that it is impossible to pass a bar or shaft through them so they can be rewound. Heretofore such rolls were frequently a dead loss to the firm; but by my device it is a very simple matter to mount the roll, no .matter how large or heavy it is, and rewind it, and therefore save the paper.

The positioning of the roll in between thebrackets 78, and the engagement of the pintles with the ends of the roll, may be effected without having to lift the roll in the first place, by having the rear legs of the brackets 7-8 rest by gravity on the rear bar 6 and tilting the connected brackets forward in the manner shown in Fig. 3, while the pintles are being adjusted. It is much easier then, and after the pintles have been engaged with the end of the roll by suitably manipulating the hand-wheel 14, to lift the roll into operative position, and with the rear legs of'the brackets 7-8 supported on the bar 6; the bar'5 being turna 1c in its bearings 4 to permit of this pivotal motion.

, Having thus described my invention, what I claim and desire to secure by Letters Patentis.
