UNITED STATES PATENT CrrrcE.
JOHN TV. CHASE AND CHARLES F. CHASE, OF NORTH WEARE, NEW
' HAMPSHIRE.
SKlVlNG-MACHlNE.
Specification forming part of Letters Patent No. 42.836, dated May 24, 1864.
To all whom it may concern Be-it known that we, J. WV. CHASE and C. F. CHASE, of North VVeare,'in the county of Hillsborough and State of New Hampshire,
I have invented a new and useful Improvement in Skiving-Machiues and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
Qnr invention or improvement in skiving- I machines consists, first, in the use of a frietion roller attached to the spring-apron by means of'an inflexible frame, and in the use ofacollared screw as a stop to hold down the apron and roller; amhsecondly, in the ar rangeinent of the gear-shaft upoirthe same posts or standards which support and guide the gage-roller.
. In the. skiving-macnines heretofore in use and constructed somewhat similarly to ours, four posts have been employedtwo for supporting the gear-shaft and-two others for supporling'the pinions, thimbles,- and springs employed or setting the gage-roller. These posts cannot be cast with the bed plate on account of the difliculty ofdrawiiig the mold. Therefore two of the posts were cast separate-ly, and then fastened to the bed-plate by means of screws.
. In order to avoid expense or metal, and also to save labor, we have invented a new are ra-ngement by which the gear-shaft, frictionroller, and devices for setting the latter are all supported upon the same two posts.
- In the accompanying drawings, Figure 1 is a backview of our machine. Fig. 2 is abottom view of the same. Fig. 3 is a detached view of the collared screw. Fig. 4 represents the collar.
In the construction of our machine thebedplate A is 'cast without any posts or standards. The two posts 13 are inserted in the bed-plate. Upon these posts are placed the coiled springs C and the thimbles D, so as to slide up and down. These are held inplace by the pinions E, which have screw threads, and are capable of being raised or lowered like screw-nuts. After these pinions are placed on the posts, the latter are crowned rangement it will be seen that pinion E can be raised or lowered at pleasure by simply turning one of the cog-wheels H, both pinions rising and falling at the same time and exactly the same distance.
The rod I is inserted into the thimble D, and therefore rises and falls withthe thimble, carrying the swinging arms K and gage-roller L, which is thus adjusted to the proper height above the knife, according to the desired thickness of the leather.
Onthe under sideof the a ron N. we have arranged a l'rictionrollor, 0. Fig.2, close to the edgeot' the knife. This roller is held'in an inflexible frame, 1 which is riveted to the apron in orderto prevent the latter from twisting. Thejournalsot' this roller are made separately, (as indicated in dotted lines,) and held in place by screws lt.
The spring-apron M and .roller 0 are adjusted by means of a collared screw, R, Figs.
1 and 3, inserted into the bed-plate, the collar overlapping the edge of the apron, as seen in Fig. '1.
The detailsof construction of our machine may be somewhat varied without departing from our invention.
Having thus fully described our invention, what we claiin,and desire to secure by Letters Patent of the United States, is-
1. The friction roller O,in co1nbination with the inflexible frame P and spring-apron M, substantially as set forth.
2. The use of the above described collared screw for adjusting the spring-apron 3. Supporting the gear-shaft G upon the same posts or standards,B,which support and guide the gage roller L, substantially in the manner and for the purposes set forth.-
