SEWING-MACHINE TREADLE.

SPECIFIGATION,forming part of Letters Patent No. 270,920, dated January 23, 1883.

Application filed June 19, 1882. (No model.)

To all whom it may concern:

Be it known that we, THOMAS (J. WOOD- WARD, of New York, N. Y., and CHARLES M. FAIRBANKS, of Hartford, Connecticut, have invented new, useful, and important Improvements in Sewing-Machine Treadles, described in the specification and the drawings thereof.

The invention consists in improvements relating to the treadle-plate and the application to of rubber foot-supports thereto, and to the construction of the foot-supports.

Figure l is a top view of a sewing-machine treadle-plate detached from a sewing machine and showing our improvements. Fig. 2 is a vertical section of a portion of the same. Fig.

3 is a detailed view of one of the rubber footsnpports.

1n the form ofconstruction shown the treadleplate A has round perforations a, into which are placed rubber foot-supports b. These rubber foot-supports are in the form shown in Fig. 3, and have a body, 0, and flanges d 0, so that they can be sprung intoposition in the treadleplate and reversed when worn. They may, how- 2 5 ever, be made in any desired form-as square or triangular-to adapt them to treadle-plates having different-shaped perforations; or the treadle-plates may be varied in construction to adapt them to the foot-supports. The 0 foot-supports prevent the foot of the operator from slipping, and also prevent the heat and electricity from bein g conducted therefrom, and at the same time give an easy elastic motion between the foot and treadle-plate. The foot-supports may be made of any other material that will answer the same purpose, as a composition of cork and rubber or felting; but rubber is preferable. I

The details of construction and operation may be varied from that shown and described within the scope of our improvements. For example, the foot-supports may be grooved and have flanges, or they may otherwise be made smaller in the middle than at the ends, or enlarged at one end or both ends, to keep them 5 in position in the treadle-plate.

We claim as our invention- 1. The combination, with treadle A, having holes a, of rubber foot-supports I), having body 0 and flanges d e, substantially as set forth.

2. The combination, with a treadle having suitable perforations, of rubber foot-supports grooved to be sprung into the perforations, substantially as set forth.

3. The combination, with a treadle having suitable perforations, of an elastic foot-support having a permanent enlargement to hold it in position, substantially as set forth.

4. An elastic foot-support especially adapted to a sewing-machine treadle, and having a permanent enlargement to hold it in position in a perforation in the treadle, substantially as set forth.

In testimony whereof we hereunto subscribeour signatures, in the presence of two attest- 5 ing witnesses, on the 23d day of March, 1882.
