M NDREL- Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed May 11, 1906. Serial No. 316,314.

T on whom it may concern:

Be it known that I, BENJAMIN PAUGH, a citizen of the United States, residing at Parsons, in the county of Tucker and State of West Virginia, have invented a new and useful Mandrel, of which the following is a specification.

This invention has relation to mandrels especially adapted to be used for winding rolls of paper; and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to providea mandrel with a web which is adapted to be laterally extended with relation to the exterior surface of the mandrel, so that when the paper is rolled upon the mandrel and the said web is extended that the central opening of the roll of paper will be of greater diameter than that of the mandrel proper. Consequently when the roll is completed the said web may be withdrawn within the mandrel, and the said roll of paper may be readily slipped from the end of the mandrel. Suitable mechanism is provided for the extending or withdrawing of the web with relation to the exterior surface of the mandrel.

In the accompanying drawings, Figure 1 is a top plan view of the mandrel. Fig. 2 is a longitudinal sectional view of the mandrel, and Fig. 3 is a horizontal sectional view of a portion of the web and its immediate operatmg connections.

Mandrel 1 is hollow and is provided at one end with a suitable handhold 2. The gearwheel 3 is located upon the said mandrel, or any other suitable means of rotating the same may be provided. The. collar 4 is also located upon the exterior surface of the mandrel, and the surface 5 is located between the collar 4 and the gear-wheel 3 and affords a bearing-surface for any suitable pattern of bearing. (Not shown in the drawings.) The mandrel 1 is provided with a longitudinallyextending slot or opening 6. The outer edge of the web 7 is located in said opening when the said web is withdrawn and passes through the said opening when the said web is projected with relation to the outer surface of the mandrel. The pins 8 8 extend transversely across the diameter of the mandrel 1, and the web 7 is provided with the inclined perforations 9, which receive the said pins 8. One end of the web 7 is provided with the vertically or transverse extending elongated perforation 10. The shank 11 is located within the mandrel 1 and is provided with a transverse-extending pin 12, which passes through the perforation 10 of the said web 7. The said shank 11 is adapted to move longitudinally, but is held against rotation. The said web 7 is adapted to move longitudinally and laterally simultaneously, but is held against rotation with relation to the mandrel 1 by means of the edges of the slot 6. The end of'the shaft 13 is swiveled to the end of the shank 11. Any suitable joint, such as 14, may be employed for this purpose. The shaft 18 is also housed within the mandrel 1. The shaft 13 is provided with a laterally-extending pin 15, which passes through the spirally-inclined slot 16, located on the side of the mandrel 1.

The operation When it is desired to project the edge of the web 7 with relation to the exterior surface of the mandrel 1, the pin is moved through the length of the slot 16. tion of the said slot moves the shaft 13 longitudinally and simultaneously rotary with relation to the mandrel 1. The shank 1.1 is slid longitudinally within the mandrel 1. The web 7 moves longitudinally and simultaneously laterally with relation to the mandrel, and thus its outer edge is projected through the slot 6. The movement of the web 7, above indicated, is accomplished by means of thednclination of the perforations 9, receiving the fixed transversely-extending pins 8. The laterally-extending perforation 10, receiving pin 12 of the shank 11 permits of the lateral movement of the web 7 with relation to the said shank. In order to withdraw the edge of the web 7 within the slot 6 of the mandrel 1, the operation above described is reversed.

of the device is as follows:'
