Specification of Letters Patent.

Patented Jan. 23, 1917.

Application filed July 9, 1913. Serial No. 778,082.

To all whom it may concern:

Be it known that 1, WILLIAM E. SPARKS, a citizen of the United States, residing in the city and county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

This invention relates to planes, and more particularly to a novel construction of sheet metal planes.

Certain features of my improvements are especially applicable to planes of the smaller sizes which are known as pocket planes or toy planes, but the invention is not limited in this particular.

The primary object which I have in view is the provision of a light, handy, efficient and durable plane, in which the number of parts is reduced to a minimum, and which can be readily and cheaply manufactured.

To this and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a side elevation of a plane embodying my improvements, Fig. 2 is a top plan View of the same, Fig. 3 is a section on line 3-3 of Fig. 2, Fig. 4 is a front end elevation of the plane, Fig. 5 is a rear end elevation thereof, Fig. 6 is a section on line 66 of Fig. 1, Fig. 7 is a top plan view of the frog, detached, Fig. 8 is a top plan view of the clamp, and Fig. 9 is a bottom plan View of the clamp.

Referring to the drawing, the body or stock 10 is of the usual channeled form and it is preferably constructed of sheet metal. The frog 11 has the usual relation with respect to the throat 12 and said frog is con structed of a sheet metal plate l1 having downturned side portions 11 fitted within and against the side walls of the stock. In order to secure the frog firmly in place in the stock, it is necessary to employ only two fastening members such as the rivets 13, 14. These rivets pass through the extensions 11 of the frog into and through the respective side walls of the stock. It will be noted from a comparison of Figs. 1 and 3 that the rivets 13, 14 are out of line with each other whereby any turning or rotary movement of the frog relatively to the stock is absolutely prevented simply by the use of these two fastening members, one associated with each of the side walls of the stock.

At the rear of the frog the same is provided with integral downturned lugs 15, 16 provided with threaded perforations for the shank 17 of the adjusting screw 18. The cutter or bit 19 is supported on the frog 11 in the usual manner and it is of'customary form except for the fact that its rear extremity is provided with a transverse slot 20 to receive the milled head 21 of the adjusting screw 18. The peripheral portion of the head 21 extends through the slot 20 for a slight distance, and as the adjusting screw is turned, the head thereof will turn freely in the slot 20 thereby advancing or retracting the cutter 19 according to the direction in which the screw is rotated. In other words, the slot 20 in fitting over the head 21 interlocks the cutter and the adjusting screw against relative longitudinal displacement while permitting the rotation of the screw relatively to the cutter.

The frog 11 carries a pivot or stud 22, and the cutter is provided with the usual slot to fit over this stud 22. The clamp 23 consists of a sheet metal plate having downturned edges 24 and a keyhole slot 25 adapted to cooperate with the stud 22 in the usual manner. At the rear extremity of the clamp 23, the same is provided with a threaded socket 26 through which a clamping screw 27 passes into engagement with the upper surface of the cutter or bit. The cooperation between the clamping screw 27, the clamp 23, the stud 22, and the bit 19 is more or less usual and need not be further described.

In order to afford a convenient and handy grip for the workman, the stock is provided at the rear end with a palm rest 28. This consists of an upwardly directed sheet metal plate having a convex rear surface and forwardly extending lugs 29 fitting between and against the side walls of the stock. The palm rest is substantially U- shaped in cross-section, the upper edge 28 being rounded and the lower edge 28 straight and horizontal and fitting snugly against the top surface of the bed of the stock. The lugs or extensions 29 are secured to the side walls of the stock by rivets 30, 31 or similar fastening members. The rivets 30, 31 are offset from each other as in the case of the rivets 13, 14 so that turning movement of the palm rest relatively to the stock is absolutely prevented without the employment of additional fastening means. Preferably, the forwardly and upwardly curved plate 28 forming the palm rest is located at the rear extremity of the plane body or stock, and is spaced from the frog and cutter located'at'the intermediate part of the stock so that the adju'stingscrew may be located between the palm rest and cutter. The rear surface of the palm rest curves forwardly in order to 'fitthe palm of" the operator, and'the form of the palm rest, is such that it merges from a shallow U-shaped cross-section'near the top into a deeper U-shaped cross section atthe bottom where the -forwardly directed extensions 29 are provided.

I do not laim herein the combination witha stock havingupright sidewalls, of afrog comprising a sheet'metal platehaving integral downturned side memberssecured to'the side walls of the stock, and integral downturned lugs "for 'the bit adjusting screw, one of said lugs bein'g struck out from the rear edge ofthe frog, and the other being struck out of: an opening at'ithe intermediate portion of the'frog, as claimed in my co-pen'dingapplication, Serial No. 778,088.
