MARKING-GAGE.

SPECIFICATION forming part of Letters Patent No. 310,964, dated January 20, 1885.

Application filed August 14, 1884. (No model.)

To all whom it may concern.

Be it known that I, RANsoM STEELE, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Marking-Gages, of which the following is a specification.

In the accompanying drawings, Figure 1 is a plan View of my improved marking-gage.

to Fig. 2 is a side elevation of the same. Fig. 3 is a reverse plan view of the same; and Fig. 4 is a transverse section thereof on line at x of Fig. 1.

I make the gage'bar in two parts, A and I 5 B. The shape of these bars in cross-section is clearly shown in Fig. 4, in which it will be seen that the bars are troughed-shaped and slide one within the other. The outer part or bar, A, has the usual marking spur. a, se-

cured to a solid portion on its under side near the end, as shown. The under side of this, bar is also provided with a slot which receives a sliding block or tenon, c, Fig. 3, to which another marking-spur, b, is secured.

The outer end of the inner bar, B, is provided with a flange or shoulder, d, to serve as a finger-piece in drawing out the bar. The gage-block C, as usual, embraces the entire bar, and it is provided with aset-screw, e, the

0 end of which bears upon the upper side of the bar B, for securing the bars in their adjusted position. The gaging face plate 0 of the gage-block is hinged thereto, so as to adjust it for gaging different bevels. The hinge pivot or axis on which the face-platec swings is in the same plane as the under face of the gage-bar, and is but little back of said face,

as shown in Fig. 2. This face-plate is provided with an arm, f, upon its back side, and

0 the block 0 is provided with a socket which receives said arm, and with a set-screw, g, which extends through one of the side walls of said socket, for fastening the arm f and faceplate 0 in their adjusted positions.

5 As illustrated, the device is represented as adjusted for marking two lines upon the surface of a block or board which has a slightlybeveled edge. If desired to set the face-plate c to a different bevel, the set-screw g is loosened, the face-plate 0 turned on its hinges to l the desired bevel, and then the set-screw is tightened to hold the face-plate in place. If desired to adjust the marking-spur b to a different point, it is only necessary to loosen the set-screw 6, then slide the bar B within the bar A without moving the block 0, and then tighten the set-screw e to hold the parts in place. It is also evident that the gage-block may he slipped along to any desired position upon the bar A, either with or without adjusting the inner bar, B, to a different position. In case it is desired to use only one of the marking-pins, the inner gage-bar, B, may be drawn back until its spur b is within the notch h in the face-plate c, where it will be out of the way, and the device may be used the same as a gage for marking a single line.

When it is desired to use the gage on a piece having a right-angled corner, the setscrew 9 is loosened and the face-plate cturned on its hinge until its upper edge comes in contact with the under surface of the block C. Said parts, in connection with the hinge, act as a stop to arrest the face-plate 0 when it is in its proper position square with the gagebar, so that the use of a square to set the faceplate by is unnecessary.

By the employment of the arm f and setscrew g, both arranged below the upper face of the gage'bar, as a fastening mechanism for the face-plate c, I. am enabled to adjust the face-plate to different bevels, and at the same time have the block free from inconvenient projections.

I Bylocating the axis of the face-plate ashere- 5 inbefore described there is but a small opening or space left between the upper edge of the face-plate and the gage-bar when the faceplate is set for use on beveled corners. In other words, the face-plate is always in close 9 proximity to the gage-bar.

I am aware that prior patents show gages the blocks of which have an adjustable faceplate; and I am aware that prior patents show gages in which the bar is formed in two parts sliding one within the other and each provided with a marking-spur. Such gages are hereby disclaimed.

I'claim as my invention it 1. In a markinggage, the combination of I00 the gage-bar, the block 0, having the ai'm-i'e- 2. In a marking-gage, the combination of ceiving socket, and the set-screw g, which exthe gage-bar, the block G, the face-platehinged tends through one of the side walls of said to said block at a point just back of its face socket and the face-plate c, hinged to said and in the same plane with the under face o 5 block and having on its back side the armf, the gage-bar, substantially as described, and 5 which extends into the socket in the block 0, for the purpose specified. the entire face-plate and its fastening-screw RANSOM STEELE. being located below the upper surface of the gagebal, substantially as described, and for XVitnesses:

JAMES SHEPARD,
