FRANK SCELZA', OF HARRISGN, NEW YORK.
To all whom it may concern:
Be it known that I, FRANK ScELzA, a subject of the King of Italy, residing in Harrison, in the county of VVestchester and State of New York, have invented certain new and useful Improvements in Door Jamb Setters, of which the following is a specification.
My invention relates to devices for setting door-jambs, and particularly to an attachment to such devices whereby the mortise of the door hinge may be located in position and cut by means of guides which insure the correct cutting of the mortise.
My invention consists in gages adjustable upon the door frame for the purpose of locating the position of the said mortise, and adjustable guides carried by the said gages for guiding tools employed to cut the mortise.
One practicable manner of employing my said invention is illustrated in the accompanying drawings, wherein Figure 1 is a plan view of a door-jamb setting frame illustrating my invention applied thereto. Fig. 2 is a cross-section on the line 22 of Fig. 1. Fig. 3 is an enlarged face view of parts of the frame illustrating the tool-guiding means for cutting the depth of the mortise. Fig. 4 is a view similar to Fig. 8, the parts of the frame there shown being omitted, and illustrating tool-guiding means for cutting the width of the mortise. Fig. 5 is a view of part of the frame. Fig. 6 is a cross-section on the line 6-6 of Fig. 5; and Fig. 7 is a detail section on the line 77 Fig. 4.
My invention may be employed in connection with any suitable door-jamb setting frame. As illustrated it is applied to such a frame, which I will designate as a whole by the letter A, which has relatively ad justable parts. Said frame is composed of uprights a a, each of which is of two pieces relatively adjustable or extensible through a tongue a having beveled edges which are received in an undercut groove a of the opposite part of the upright, as seen in Fig. 6. A set screw (4*, holds the two parts of the upright when adjusted in position. Upright a is similarly equipped with tongue, groove and set screw. These uprights are connected by cross-braces a a which are also extensible, and are similarly provided with tongues and grooves and set screws to permit such extension. Said frame is Specification of Letters Patent.

equipped with levels a a for plumbing the frame.
As convenient means for holding the hinge-setting devices I may construct chan' nels a upon the outer sides of the uprights a a These channels are located at about the position the hinge will come and are of sutlicient size to provide a reasonable margin for the location of such hinges. Within these channels where they are employed 1 locate the devices for determining the position of the hinges and for guiding the tools in cutting the mortise. These devices constitute my invention. As shown the said devices comprise gages B of which I prefer to-employ a pair for each hinge, and as the gages in each pair are similar in construction I will describe one of them. Each gage B is adjustable up and down or lengthwise of the frame A, and relatively to its mate and has means provided for the purpose of permitting such adjustment and of securing the gage in position in said frame, which as illustrated comprise a tongue Z2 which enters an undercut groove 6 in the frame, whereby the gage is held in position and is permitted to slide up and down in said groove. A set screw 6 may be provided to retain the gage in adjusted position. The gage is preferably equipped with an arm 7) which. is arranged parallel with the face of the frame, and serves to embrace the end of the doorjamb C. This arm on its outer face has an undercut groove 5* within which slides a block 6 A set screw b passes through a slot 6 in said slide, serving to hold it in position. Upon this slide is mounted a pin .71 and a tool guide 6 is slotted at 7) I), and the said slots receive upper and lower pins 5 The inner horizontal edges of the arms 72 as shown may be beveled atthe top to allow the chisel to slip easily ofl' same and pre vent the dulling of the chisel. Below the beveled portions said edges are straight edges which serve to guide the tool in making the upper and lower cuts for the depth of the hinge, and the inner or left hand edge of the tool guide as shown has also a straight edge and serves to guide the tool in making a vertical cut for the depth of the mortise. The gage B is also preferably provided with a rearwardly extending arm I), seen in enlarged view in Fig. 1, which is perpendicular to the arm 6 and embraces the face of the door-jamb C or that part of i The tool guide 6 as also the tool guide I)",
are adjustable in and out upon the said arms, and the slots contained therein permit the adjustment of the arm of the gages B relatively to each other. The inner opposite edges of the arms I) are straight edges for locating the position of the upper and lower sides of the hinge and constitute tool guides for cutting the mortise at such points. They may be beveled at their upper edges as are arms The inner face of the tool guide 6 9 also locates the width of the mortise for the hinge and constitutes a guide for the tool employed to make such cut.
In operation the frame A may be laid upon the floorand the door-jamb secured to the outer parts thereof in any suitable manner, as by clamps if desired; the frame and door-jamb will then be erected in position in the doorway as usual and trued up by means of the levels, the usual blocks being inserted if necessary for the purpose of holding it plumb. After the door-jamb has been secured the gages B may be adjusted to the'position which it is desired the hinge shall have. The set screws 79 may then be .screwed on the jamb. The arms 72 will then be at the side of the jamb G and the arms I) at the face thereof. The set screws 1) may then be loosened and the slides 19 adjusted so that tool guide Z2 will indicate the proper depth for the hinge when the said set screws will be tightened. Slides Z2 will then be adjusted until the tool guide (2 shall indicate the proper width of the mortise for the hinge. -A chisel may then be employed against the straight edges of arms o and tool guide 6 to make the cuts in the face of the jamb for the hinge mortise, and suitable chisels against the straight edges of arms 12 and tool guide 6 to remove the said material to a proper depth. The tool guides 6 and b may be held upon their supporting pins by set screws if desired.
While I have illustrated my invention as applied to an adjustable door-jamb setting frame in connection with which it is extremely useful, I do not regard it as limited in its application to such construction of frame, nor is it to be understood by reason of the particularity with which I have described the construction of my improved gage and the manner for permitting the adjust-ment of the various parts and securing the same in position, that I regard my invention as necessarily limited to these particular details, as equivalent means may be employed without departing from the spirit of the invention.
