TOOL FOR CUTTING WlNDOW-JAMB POCK ETS SPECIFICATION forming part of Letters Patent No. 728,843, dated May 26, 1903.

Application filed June 14, 1902.

T0 aZZ whom it may concern: I

Be it known that I, FIRMAN HARES BOR DEN, a citizen of the United States, residing at Vincennes, in the county of Knox and State of Indiana, have invented a new and useful Tool for Cutting WVindow-Jamb Pockets, of

which the following is a specification.

This invention relates generally to carpenters tools, and more particularly to a marking or cutting gage, the object being to provide a simple and efficient device for cutting pockets in window-jambs, also to provide one which is quickly and easily adjusted, and also to provide one which will be protected against damage when not in use.

A further object of my improvement is to provide a tool for conveniently cutting weather-boards to fit under window and door sills, and, in fact, for gaging and cutting any thin board, and thereby avoiding the necessity of sawing it, as in the means now em- Dloyed.

With these several objects in view the in-' vention consists in the novel features of construction and combination, all of which will be fully described hereinafter and pointed out in the claim.

In the drawings forminga part of this specification, Figure l is a perspective view illustrating the practical application of my invention. Fig. 2 is a detail perspective view of a tool constructed in accordance with my invention, said tool being shown in the position in which it is placed when not in use. Fig. 3 is a sectional view illustrating the operation of the tool, the rod being shown in elevation.

In the practical embodiment of my invention I employ a round metal rod or bar A, preferably about twelve inches in length, said rod having a handle B rigidly connected to one end thereof, and also rigidly mounted upon the rod adjacent to the handle is a gageblock 0, essentially semicircular in shape, the straight face of said block being rabbeted or shouldered at the inner edge, as shown at G, for the purpose of engaging the edge of a board or strip while being cut, and thus providing a suitable guide for the tool.

The rotary cutter or gage-knife E is loosely mounted upon the rod A within the vertical Serial No. 111,690. (No model.)

slotted frame F, one side F of the said frame extending downwardly and being adapted to extend into the groove of the window-jarnb when the jamb is being cut, and thereby providing a positive guide for the cutter, the said frame having a horizontal bore for the purpose of receiving the said rod, and in order to securely fasten the frame upon the rod I employ a set-screw F working through one side of the frame and bearing upon the rod, as most clearly shown in Fig. 3.

The side F, which projects below the main portion of the frame F, may be integral with the said frame or separable therefrom, as preferred.

In practice I prefer to make the set-screw F of such length that its head will project above the cutting edge of the rotary cutter or wheel E, so that when not in use the tool can be laid as shown in Fig. 2, in which position it will be noted that the tool rests upon the curved portion of the head-block (J and the head of theset-screw F thus supporting the cutting-blade away from the table or other article upon which the tool rests.

Various sizes of wheels or blades may be employed, according to. the character of the work to be done, as it is obvious that my tool can be used as a gage-marker as well as a groove-cutter.

In operation the carriage carrying the blade or wheel is adjusted upon the rod, and the head-block is then moved into engagement with the edge of the jamb to be marked or cut. The handle B is grasped in one hand, and the free end of the rod is grasped in the other hand, and the tool is then forcibly moved along the face of the jamb, forcing the cutter into the Wood, and thereby quickly and effectively cutting the jamb and leaving In a device of the kind described, the combelow the edge of the frame, and a. set-screw bination with a. rod having a, rigid handle at adapted to clamp the frame to the rod. one end, of a gage-block rigidly secured to the rod, said block being cut away adjacent FIRMAN HARES BORDEN' 5 its lower edge, a frame slidably carried by Witnesses:

the rod, 2, cutting-disk revolubly mounted on MARSHALL MCDONALD, the rod within the frame, the disk extending HOMER A. FIELD.
