BENCH- PLANE.

SPECIPICATION forming part of Letters Patent No. 371,482, dated 11, 1887.

Application filed Mart-h 12, 1887. Serial X0. 230,651.

whereby the stock of the plane may in effect be lengthened to enable one plane to servethe purpose of one or more planes of greater length than the plane to which the improvement is applied.

In the accompanying drawings, Figure l is an isometric perspective view of a plane with my improvement applied thereto; Fig. 2, an isometric perspective view of my improvement detached; Fig. 3, a vertical cross section on the line w w in Fig. 5; Fig. 4, a central longitudinal section of the rear part of the plane proper and the rear part of my improvement; Fig. 5, a central vertical section of my improvement and a side elevation ofthe plane.

The improvement, hereinafter described, may be applied to any so-called iron benchplanethat is, a benclrplane having an iron stock-and is here shown as used in connection with a Bailey smooth-plane, the construction of which is well known and needs no particular description.

It is sufficient to say that A represents the stock, a the planeiron, and H H the planehandles.

The only change that requires to be made in the plane proper to enable my improvement to be applied to it is to form two grooves, a, one on each side of the stock leading from near the point of the same to said point, and providing the handle H with a depression, 71, for purposes hereinafter stated.

My improvement consists of a shoe, S, which in general appearance is like the bottom and sides of the stock, but longer, and provided with an opening, 8, through the bottom of the same, of a shape and size adapted to receive and fit the sole of the stock A. The shoe S is provided with pins 8, (shown in Figs. 2,3,and 5,) adapted to enter the grooves (No model.)

a and to fit the same, and is also provided wit-h a vertical post, 8, arranged in the rear of the slots, which vertical post supports an inclined screw, 8", the head a" of which is preferably milled to enable it to be turned readily by the fingers, the point of said screw entering the depression it, above mentioned as being formed in the handle II, to prevent the rear end of the plane from rising out of the slot 8. The relative positions of the grooves a, pins 8, screw 8 and depression h are such as to hold the soleof the stock A and the bottom of the shoe S in the same plane, the rear ends of the grooves a being at the same height above the sole of the stock as the pins 8 are above the bottom of the shoe, and the deepest part of the depression h fitting the point of the screw 5 and being at the same height above the sole of the stock as the point of said screw, when turned into said depression, is above the bottom of the shoe. The depression h, instead of being made directly in the wood of the handle, is preferably made in the head of a metallic screw, h, driven into the handle against the screw h", which secures the handle H to the detachable face-plate.

The plane is inserted in the shoe-point first and pushed forward until the pins 5 reach the rear ends of the grooves a, and the rear of the plane is then depressed until the lower surfaces of the stock A and the shoe S are in the same plane. By loosening the screw 5- the rear end of the plane may be lifted out of the slot 8, and the stock being then drawn backward is disengaged from the shoe.

By means of the improvement above described a common smooth-plane can be used with the shoe as a foreplane or jointer, and the expense of such a shoe is trifling compared with the cost of a plane, and the time required to apply or remove the shoe is of no importance.

I claim as my invention- 1. A shoe provided with a slot adapted to receive a plane-stock and means, substantially as described, of holding the bottom of said shoe in the same plane with the bottom of said stock, as and for the purpose specified.

2. The combination of the plane having a handle, and having a stock provided with lower surfaces of said stock and shoe in the grooves near its point, and a shoe slotted to same piano, as and for the purpose specified. receive said stock, and having inwardly-projecbing pins adapted to enter and fit said EAMOR TEED' 5 grooves,and having a post, a screw turning in Witnesses:

saidilpost and thrusting into a depression with ALBERT M. MOORE,

which said handle is provided to hold the EDWARD W. THoMrsoN.

It is hereby certified that the name of one of the assignees in Letters Patent No. 371,482, granted October 11, 1887, upon the application of Eamor A. Teed, of Lowell, Massachusetts, for an improvement in Bench-Planes, was erroneously written and printed Frank B. Low, whereas said name should have been written and printed Frank B. Dow. Also that errors appear in the printed specification requiring correction as follows: Ln line 75, page 1, the word face-plate should read shoe and in line 76, same page, the hyphen between the words shoe and point should be stricken out, and that the Letters Patent should be read with these corrections therein that the same may conform to the record of the case in the Patent Office.

Signed, countersigned, and sealed this 8th day of November, A. D. 1887.
