UNITED STATES PATENT OEEIcEo HENRY A. FOSS, OF PINE MEADOV, CONNECTICUT, ASSIGNOR TO PHILIP E. CHAPIN, OF SAME PLACE.

IMPROVEMENT IN BENCH-PLANES.

Specification forming part of Letters Patent No. 207,599, dated September 3, 1878; application filed April 15, 1878.

To all 'whom it may concern:

Be it known that I, HENRY A. Foss, of Pine Meadow, in the countyr of Litcheld and State of Connecticut, have invented certain new and useful Improvements pertaining to a Carpenteris Plane, of which the following is a speciication, reference being had to the accompanying drawings, where- Figure 1 is a top view of a plane embodying my improvements. Fig. 2 is a side view of same. Fig. 3 is a bottom View of the fastening-lever. Fig. 4. is a View of the fasteninglever in central longitudinal section. Fig. 5 is a side viewof the lower end of the fastening-lever;

The letter a denotes the body or stock of a metallic plane. b denotes the plane-iron, which may or may not be supplemented by a cap-iron lying on a proper bed and running down to the throat. The letter c denotes the fastening-lever, bearing on its sides the fulcrum-ears d d, resting in the fulcrum-mortises e e, which are made in the plane-stock, provided near the upper end with the tighteningscrew f, and at the lower end with the rocking end g, which is pivoted to the fasteninglever in such shape as to allow it to rock and adjust itself to bear squarely and flatly on the plane-iron. To secure this rocking motion, the lowerend ofthe fastening-leveris providedwith the pivot-pin h, which runs through a corresponding pin-hole, fi, in the rocking end, and is provided wit-h .a head on the under side.

v Pleferabl r the s )rino' is also secured on this .l I A c .7

pin, bearing against the under side of the rocking end.

The sides of the plane-body are provided with or shaped into the swells 7o k, and the fulcrum-mortisese-e'are made just underneath these swells. These swells allow the passage of the fulcrum-ears d d down to the fulcrummortises. Then, by sliding the fastening-lever slightly forward, the ears d d are carried to the forward ends of the mortises, which are inwardly shouldered, so that the ears lock under at this point. This construction not only allows the fulcrum-mortises to be cast, but the swells give a good gripe for the hand of the operator.

The letter l denotes a knob or handle, fastened to the fastening-lever c by having the screw Z cast in or projecting from the fasteninglever, and running into the knob. Another mode of fastening on this or such a knob is illustrated by the knob m, which is driven into the ring m', cast on or projecting from the iioor of the plane-stock.

I claim as my invention- 1. In combination with the plane-body and plane-iron, the fastening-lever c, provided with the rocking end g, substantially as described, and for the purpose set forth.

2. The fastening-lever c, provided with thc screw l', and combined with the knob l.

HENRY A. FOSS.
