COMBINATION SQUARE AND GAGE.

SPECIFICATION forming part of Letters Patent No. 329,156, dated October 27, 1885.

Application filed July 20, 1885. Serial N0.1I2,085. (No model.)

To all whom it may concern:

Be it known that I, WM. FORD, of Birmingham, in the county of New Haven and State of Connecticut, have invented a new Combination Square and Gage; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a perspective view of the instrument, showing all the parts set together; Fig. 2, a perspective view of the stock as a level, and with the depthgage introduced in broken lines; Fig. 3, the stock and blade set as an L- square; Fig. 4, the stock and bevel blade; Fig. 4", a transverse section through the collar and blade; Fig. 5, the. stock and beam as set for a surface-scratch; Fig. 6, the stock, beam, and scratch as set for a surface-gage; Fig. 7, a longitudinal section through the stock, square, blade, and screw; Fig. 8, a transverse section through the beam, collar, and scratch.

This invention relates to a combination or convertible instrument, specially adapted for machinists uses, the object being to adapt the several parts to be interchanged to produce several instruments-such as spirit-level, L- square, T-square, thread and drill gage, bevel, surface-scratch, surface-gage, and depth-gage; and the invention consists in the construction, as hereinafter described and particularly recited in the claims.

A represents the main stock or body of the instrument, which consists of a metal bar having its sides parallel. In one side a bulb, a, is introduced to form a spirit-level, so that the stock may be used, as in Fig. 2, for leveling purposes. At one end of the stockis a longitudinal slot, 6, adapted to receive the blade B, which. forms the squares.

Transversely through the slot a set-screw, C, is introduced, and the blade at about mid way of its length is constructed with a hole,

6, to enter the hole in the blade and act as a wedge or cam to force it to a bearing in the stock. At one end of the blade a like hole, f, is made, so that the blade may be set to form an L-square, and as seen in Fig. 3, or set midway of its length to form a T-square, as seen in Fig. 1.

D is the bevel-blade, which is constructed with a longitudinal slot, E, in the usual manner for bevel-blades. This slot is of dovetail form in transverse section, .as seen in Fig. 4, and into the slot a collar, F, is placed adapted to slide in the slot. The under side of the collar is a little short of the under face of the blade, as seen in Fig 4, and so that when the blade lies upon the, stock, as seen in Fig. 4, the screw introduced through the collar will force the collar hard against the blade and the blade upon the stock, so asto firmly set the blade at any desired point. Then by loosening be shapedI make a V-shaped notch, g, in the end of one or both the blades, the angle of the V being that required for such tools.

G is the gage-beam. It is adapted to slide through a corresponding hole, H, transversely through the stock. At one end it is provided with a tooth, h, to scratch the surface, and is held in the stock by a set-screw, I, preferably introduced through the end of the stock to bear against the beam, and as seen in Figs. 1 and 5. The stock serves asthe head or body of the gage to govern its movement, and the point to mark the surface over which the gage is run.

As a surfacegage, the beam is constructed at the end opposite the tooth with a longitudinal screw-stud, 2', adapted to enter the opening at the slot end of the stock, and from which the screw C is removed, and so that the beam may be screwed hard down upon the surface of the stock, as seen in Fig. 6.

On the beam is an adjustable collar, L, adapted to slide on the beam, and transversely through it is a hole, Z, through which a scratch, M, may be set and wedge against the beam so as to hold the collar at any point to which it may be set. The collar being placed at the required distance for the scratch, the scratch is introduced and forced tov abearing, sov as to secure the collar, and thus securing the collar 4 holds the scratch in the proper relative position to the face of the stock, and so that the stock may be placed upon the surface upon which the gage is to rest, and the scratch serve to mark in the usual manner of using a surface-gage. One of the points of the scratch is in axial line and the other turned at right angles, in the usual manner for the instrument called a scratch! As a depth-gage a hole, 42, is made through the stock at the end opposite the slot, at right angles to the beam-hole H, this hole or corresponding substantially to the size of the scratch, and so that the scratch inserted through it, as indicated in broken lines, Fig.

' 2, may be fixed at any desired position by means of the set-screw I, therefore the stock resting upon the surface, and the scratch introduced so as to project from the lower side to the depth required, and there set by the screw I, the depth-gage is ready for use.

The square blade may be provided with a series of graduated openings as a gage for screws, drills, &c.

In order to introduce the beam G through the stock the hole H is constructed at one point with a longitudinal recess, m, through which the tooth h may pass, and so that the beam may be readily introduced or removed by placing it in position to allow the tooth to pass through the recess m.

The square and bevel blades may be omitted, the stock, beam, and scratch forming all the instruments except the square and bevel.

The blades may be graduated in the usual manner of graduating such blades for machinists purposes.

I claim- 1. The herein-described combination-tool, consisting of the stock A, provided with the level-bulb a, and constructed with a slot, 12,

at one end, a blade, B, constructed to enter said slot, a screw, 0, in the stock, to secure said blade in its slot, a bevel-blade, D, constructed to be applied to the surface of the stock and be also secured by the said screw 0, the stock constructed with a hole, H, transversely through it, a beam, G, adapted to slide through said hole H in the stock, a setscrew, I, in the stock to secure said beam,'the said beam provided at one end with a tooth, h, and at the other with a longitudinal screw, 1', said screw 71 adapted to enter a corresponding hole in the stock, and a collar, L, adjustable on said beam, and with a hole through it at right angles to the beam, with a scratch, M, adapted'to pass through said transverse hole in the collar, all substantially as described.

2. The beam A, the bevel-blade D, con-- structed with a longitudinal slot of dovetail shape in transverse section, combined with a through said hole, set-screw I, to adjustably secure said beam in said stock, thebeam provided at one end with a scratch-tooth, h, and at the other with a longitudinal screw-stud, z, the stock constructed with a screw-threaded hole corresponding to said stud z, and collar L, adjustable on said stock, and adapted to carry the scratch M, substantially as and for the purposes described.
