Application filed October 7, 1914. Serial No. 865,483.

Toyall whom it may concern Be it known that 1, WILLIAM S. BURK- HART, a citizen of the United States of America, and resident of Martins Ferry, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Carpenters Tools, of which the following is a specification.

This invention relates broadly :to an improvement in carpenters or joiners tools, and specifically to a tool for holding doors and windows while the same are being planed ofi'- The primary object of the invention is to provide a device by means of which a door or window mayberigidly held while its edges are being planed off itofcause it to fit within the frame provided therefor.

A. further object is to provide a simple, inexpensive and efficient device of .the character mentioned which maybe conveniently mounted upon adoor frame,=window frame, or window sill and which is adapted to maintain a door or window in a stationary position during the planing operation.

With these and other objects in view, the invention resides in the features of construction, arrangement of parts and combinations of elements which will hereinafter be outer edge view of the invention applied to a window sill; Fig. 3 18 a longitudinal section of the invention; and-Fig. a is an enlarged section on the line Fig. 3.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views, 1 indicates a metal bar which has one end turned at substantially a right angle to its body to form an arm 2. Threaded through said arm and lying in parallel alinement with said body is an adjusting screw 3 having a bear ng plate or disk at swiveled on its end, said disk being adapted to seat against the side of a door casing 5, window frame 6, or like surface, in opposing relation to a jaw 7 which is seated against the opposite side of such frame or casing. While said jaw may be stationarily mounted on the bar 1, it is preferably adjustable, thus adapting the de- Specification of Letters Patent.

vice for application to casings or frames of widely varying thicknesses. Said j aw is substantially triangu'l'arin form and has a taperedy-opening 8 extending :therethrough in which. said bar is received. In an .outwardly :tipped position, said jaw is freely slidable upon the bar; but when disposed substantially at a right angle to said bar, a transversely disposed pin '9 carried thereby seats in one of a series of notches 10 formed in ,said bar so that the jaw is maintained against rearward movement.

Carried upon theou-ter end of the bar 1 is aclamp. adapted for receiving the edge of a door-or window sash therein. Said clamp consists ofa U-sha'ped element 11 having an adjusting screw .12 directed transversely through ,oneof the parallel members thereof, said screw having is-wiiveled thereon a disk 1-3 adapted to impinge upon a face of a door whose edge is received between said parallel members. H hile said clamp may be rigidly mounted upon, or formed integral with, the bar 1, it is preferably mounted on said bar in the manner herein illustrated. As shown, the bar 1 has a short reduced portion 14, rectangular in cross section, adjacent to its end, and terminates in a cylindrical stem 15 of less diameter than said reduced portion. The outer end of said stem has an upset end or head 16 between which and the end of said reduced portion is a stem-encircling spiral spring 17. The element 11 has a centrally disposed rearwardly extending hollow stem 18, the bore of which is rectangular adjacent to its rear end, as is clearly shown in Fig. 4c, loosely fitting the reduced portion 1a of the bar 1. Joining the rectangular portion of the bore is a circular portion which loosely embraces the spring 17, as shown in Fig. 3, an annular internal shoulder 19 being formed at the juncture of the said rectangular and circular portions of the bore.

The spring 17, the inner end of which until the rectangular portion of the bore is withdrawn from the rectangular reduced portion 14 of the bar, whereupon it is given a quarter turn in the desired direction.

By providing the above described swivel. connection between the door-clamp and the bar, the-device is rendered applicable both to a door frame,,as shown in ig. l, and to j a window sill, as shown inFig.

In practice, the device is first mounted in a istatlonary position on a mounted door frame or wlndow frame, after whlch the endof a door or a window sash, as 20, is

inserted'within the embrace of the clamp, the said door or sash being'disposed on its edge on the floor. In this position said door or sash will be held firmly while its edge is being planed off to cause it to fit the frame or casing provided therefor.

WVhat is claimed is 1." A carpenters tool of the character described comprising a notched bar having an angularly disposed member at one end, an adjusting screw directed through said member, a jaw carried by said bar in opposing relation to said screw and having a portion for engaging a notch of said bar, said jaw having a tapered opening therein rendering said jaw freely movable on said bar when it. occupies a tipped position, a door-holding Copies of this patent may be obtained for clamp at the opposite end. oflsaid bar, a swivel connection between said bar and said clamp, and means embodied in said swivel connection w'hereby said clamp is normally held against rotation. j H

2'. A carpenters tool of the character described, comprising a bar having an angua larly disposed member at one'end, an adjusting screwxdireoted through said mem- 40 her, a jaw adjustably mounted on said bar in opposing relation to said screw, saidbar having a reduced portion, rectangular in cross section',adjacentto its outer end, a door-holding clamp mounted on said outer end and having swivel connection therewith, said clamp having a portion adapted for embracing said reduced-portion whereby turning movement of the clamp is prevented, and means normally maintaining the embracing relation, sa d means admltfive cents each, by addressing the Commissioner of Ia tentsa Washington, D.
