To a-ZZ whom it may concer-n.'

Beit known that we, MILTON C. STERN and HERBERT E. NETH, citizens of the United States, residing at Dayton, in the countyof h/Iontgomery and State of Ohio, have invented certain new and useful Improvements in Autographic Registers, vof which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to autographic registers and in particular to a rewind core therefor. v n

Theobject of our invention is to provide a rewind corewor cylinder for rewi'nding a strip of paper constitutingthe Vpermanent record retained in an autographic register.

It will be understood that this rewinding cylinder must have the paper attached v`to, it permanently so that it will not slip and so that during the winding operation *the` paper will be positivelywound tightly and uniformly and without tearing. This necessitates a irm even grip upon the Paperv1t is also an object of our invention to lpermit of the attachment of the paper to the 'rewind corek easily and effectively as heretofore it has been difiicult todo.

It isa further object of our invention' to .provide an easy meansy of forming the roll so wound from the rewind core. Heretofore it hasbeen a very difficult matter to detach the paper so rewound after it had once been wound into a tight roll in the register.

It is a further object of our invention to provide an association with the rewind roll and adjustable tension devi-ce so that as the tension increases due to the increasing size of the roll, means for-"adjusting the pulley ofthe roll will be provided to maintain 'this tension at a uniform point. f

Fig.y 7' is a Similar View of another `form of gripper bar actuator.`

Fig. 8 is a section showing'tlie pin engaging withV the stub axle.v

Referring to the drawingsin detail,y 1y is a rewind roll, the core usually made of wood. This core has a passageway extending therethrough consisting of a rcenter pas-` sageway 2 and endpassageways'and V4 of larger diameter. The passageways'3`has an enlarged portion near the end as. at 5Ik for the reception of the actuator sprii'ig.`

Located in the passageway 3 is' a stubaxle retaining 7 known as the actuator axle. This axle is pinned into the roll 1 by the pin 8 `which is located transversely thereof.

This aXle 7 is surrounded near its outer endv by the spring 6 one end-`of which abuts against the end of the passagewayV 5 inthe roll 1 and theother end against the'actuator disc 9. This disc is either provided with a knurled margin 1() or studsy 11 to' facilitate the fingers of the operator enga'gingwith thedisc and rotating y'it' onv the aXle. This disc is provided with 'a slot 12 inv which there travels the end 13 of the gripper finger bar 14. The disc 9 is prevented" from moving outwardly on the aXle due tothe action on the spring 6 by a-washer4 15- which is also mounted on the` a-Xler and held in position by a collar 16 pinned to theaXle .by the pin 17. 1

The gripper bar 14 carriesl a plurality of yspaced vfingers designated 18. The bar itself woundl upon the roll the fingers 1S maybe projected'by the rotation of the disc andthe papergfirmlyengaged with thev rollsothat it cannot slip -or tear.

As the roll increases in size due to the fact that it is being` rotated for` the winding of the paper in the usual manner of autographic registers, it becomes necessary to compensate for the additional strain being put upon the paper and it becomes necessary to relieve this strain. For this purpose there is provided the `following mechanism. Another stub axle 21 has one end mounted in the passageway 2 and its outer end in the passageway et within the roll 1. A transverse pin 22 pins the axle to the roll. The portion of the axle mounted in the enlarged passageway 4 carried a collar 23 as the abutment for a helical spring 24 which surrounds this portion in the stub axle 2l. rlhe other end of this spring abuts against a steel disc 25 which is carried on the axle 2l adjacent the end of the roll 1. A pin 26 prevents this disc from rotating as the pin is mounted both in the disc and in the roll 1.

Also mounted on the axle adjacent to the disc 25 in succession is a fiber disc 2T, a steel driving gear 28, a liber disc 29, and a steel disc 30. The steel disc 30 is provided with a collar 31 which is pinned to the axle 21 by the pin 32.

It will thus be seen that the gear 28 which is loosely mounted on the axle or shaft 21 will provide the entire clutch assembly and roll until the resistance becomes sufficient to cause it to slip with respect to the roll and the clutch members 25, 27, 29, and 30, providing a means of relief for successive strain upon the paper being wound.

iVe do not desire to limit ourselves to the particular details as hereinbefore described, but comprehend within our invention a suitable modification thereof for its practice.

Having thus fully described our invention,

what we claim as new and desire to secure by Letters Patent, is: l. In a rewind roll, a cylinder for supporting the paper, a groove therein communieating with the exterior thereof, a gripper finger bar pivoted thereon below the surface of the roll in said groove, a plurality of gripper fingers mounted on said bar, an axle supporting said roll, an actuator disc mounted on said axle engaging with one end of the gripper bar and adapted upon being` rotated to vary the ngers on the gripper bar with respect to the roll.

2. In a rewind roll, a cylinder for supporting the paper, a groove therein coxnmunicating with the exterior thereof, a gripper finger bar pivoted thereon below the surface of the roll in said groove, a plurality of gripper fingers mounted on said bar, an axle supporting said roll, an actuator disc mounted on said axle engaging with one end of the gripper bar and adapted upon being rotated to vary the fingers on the gripper bar with respect to the roll, and yielding means to yieldingly resist the rotation of the' disc on the axle relative to the roll.'
