GAGE AND MARKING DEVICE.

Specification of Letters Patent.

Patented July 13, 1909.

Application filed September 21, 1908. Serial No. 453,905.

To all whom it may concern:

Be it known that I, ALEXANDER VmTon, citizen of the United States, and a resident of Canton, in the county of St. Lawrence and State of New York, have invented a new and Improved Gage and Marking Device, of which the following is a full, clear, and exact description.

This invention relates to a class of gages employed by woodworkers for marking the outlines of mortises or open recesses in casement-jambs and door stiles, to receive hinges; and the pur ose of my invention is to provide novel detai s of construction for a device of the character indicated, which is especially well adapted for the purpose specified, and which also may be used as a depthening and outlining gage for forming recesses in other constructions of wood or metal.

The invention consists in the novel construction and combination of parts, as is hereinafter described and defined in the ap pended claims.

Reference is to be had to the accompanying drawings forming a part of this s peciiication, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the improved gage and marker Fig. 2 is an edge view of the same, seen in direction of the arrow .r in Fig. 1; Fig. 3 is a reversed plan view of the gage and marker; Fig. 4 is a longitudinal sectional view, substantially on the line 44 in Fig. 1 Fig. 5 is a reversed plan view of aT-head that is a detail. of the invention, seen in direction of the arrow at in Fig. 2, and Fig. 6 is a detached plan view of an adjustable gage-block, seen in direction of the arrow in Fig. 4.

The body portion 10 of the improved tool is formed of metal, and comprises a flat slablike block of suitable thickness, and having a rectangular marginal shape. At the transverse center and at a nearly equal distance from the ends thereof, a slot a is formed in the body 10, having a considerable length.

A slidable gage-block 11 is a novel detail, and, as is best shown in Figs. 3 and 4, consists of a rectangular block of metal, having suitable width and thickness and a length equal to the width of the body 10. At the center of the gage-block a tongue 11 is formed or secured thereon, consisting of a metal strip having parallel sides and. a width that adapts it to iit neatly in the slot a. A clam ping-screw 12, having a collar l2 thereon that is integral with the knurled head 12 of the screw, is screwed through a threaded perforation in the center of the gage-block 11, after the tongue 11. is inserted into the slot a from the normally lower side of said block.

It will be noted in Fig. 3, where the collar 12 of the set-screw 12 appears in dotted lines, that the diameter of said collar is greater than the width of the slot a, and that opposite portions of the collar have contact with the upper surface of the gage-bloclr 11 near the slot, which adapts the set screw to clamp the head-bleck at any point of longitudinal adjustment for said gage-block in the slot, and hold it secured. Furthermore, as the block 11 is projected from the lower surface of the body 10, its transverse disposal thereon adapts said block to serve as an abutment for gage-markers that will be described.

Upon one end of the body block 10, as shown in Figs. 3 and 4 at the left, a short scribing-blade l) is formed or secured at the transverse center thereof, and it will be apparent that this blade, in conjunction with the gage-block 11, affords means for scribing score-lines in wood, parallel with a true shoulder on the wooden material against which the true transverse edge of the gageblock 11 is reciprocated, while pressure is applied upon the body 10 over the blade I).

It will be noted that the scribing-gage just described affords means for scribing scorelines on the flat surface of a door or casement-jamb, while the block 11 is held against and slid upon an edge or shoulder of the material at right angles to said surface.

To enable the scoring of a line parallel with a surface and at a desired depth, in a surface at a right angle thereto, means have been provided that appear at the righthand end of the body 10, in Figs. 1 to 4 inclusive, comprising the following details: A gage-screw 13, having an elongated body and a knurled head 13, is screwed into a threaded perforation in the body 10 near the right-hand end thereof, and preferably at its transverse center. Upon the gage-screw 13 a sleeve-nut 18. is mounted before the engagement of the gage screw with the body 10 and as shown, said nut is roughened peripherally to facilitate its manual adjust-' ment. A scriber-head c is secured on the threaded end of the gagc-screw 13, after it has been screwed into the body 10, preferably by means of a clamping screw and u on the lower end of said scriber-head a circular blade or V-shaped rib d is formed, as is clearly shown in Figs. 3 and 4. It will be seen that the sleeve-nut 13 serves as a j amnut for securing the scriber-head 6 projecting below the lower surface of the body 10, any distance that the length of the gage screw 13 permits, so that a sliding movement of the body 10 over a flat surface, such as the stile of a door or a casement-jamb, with the gage-block 11 in contact with said surface, will permit a score-line to be formed at a desired depth from the surface whereon the body 10 is slid in the edge of a door or a door-jamb, as the case may be.

The scribing means just described, is designed to facilitate the formation of depth lines for the embedment of large hinges having thick leaves, in the edge and jambs of heavy doors and their easements, and also for laying out mortises in doors or other Woodwork.

For forming score-lines on doors and dooreasements of ordinary thickness, a supple mentary scribing means is provided, which is shown at the left in Figs. 1 to 4 inclusive, in the drawings. Two parallel guides 14 are formed on the u per surface of the gage-body 10 and receive etween them a member of a T-shaped head-piece 15, having a transverse bar 15 formed thereon at right angles thereto. In the T-head member 15 a longitudinal slot (1 is formed, through which passes the screw threaded body 16 of a clampingscrew, the head portion 16 of which is circular, is peripherally roughened, and. has such a diameter as permits it to overlap the defining side edges of the slot 61 when the screw engages a tapped hole 0 in the body 10, said hole being formed interiorly for the reception of said screw. The transverse head portion or member 15 of the T-head has parallel sides and projects below the member 15, so as to provide a shoulder e, that is at right angles with the side edges of the tongue member 15, and parallel with the end wall 0 of the gage body 10. Centrally on the lower outer corner of the transverse member 15 a small scribing blade 9 is formed or secured, which will produce a scored line or indentation in wooden material, such as a door, along its edge that is to receive the leaf of a hinge. In this scribing device the end wall 0 of the body 10 that is nearest to the T-member 15*, becomes the shoulder that engages the surface of a door-stile, and the scriberblade 9 marks the depth line for a recess that is to receive the leaf of a hinge, and it will be seen that by an adjustment of the T-head member 15 the depth-line may be positioned at exactly the correct depth, and to facilitate such an adjustment, a scale graduation h is produced on the upper surface of one of the guides 14, on which a corner of the member 15 will register and indicate the proper depth for a recess.

It will be seen that the supplementary gage is available for marking the scores which determine the depth of a recess for the reception of a hinge leaf, and also the width thereof from the pintle-sleeve to the edge of the leaf that is opposite from said sleeve, if the hinges are of ordinary size.

As an adjustment of the gage-block 11 so as to locate it at either end of the slot (1, will locate it at some distance from the end of the gage body that is nearest to the opposite end of the slot 0, it will be seen that the gage block 11 and the side edges of the body 10 will serve as a T-square for use in marking the score-lines at the ends of the recesses for the hinges.

It is obvious that the improvement may be given dimensions that best suit its service, and that the tool complete may be made'of steel or other available metal.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
