FACE-PLATE FOR MARKING-GAGES.

EPECIFICATIQN forming part of Letters Patent No. 334,308, dated January 12, 1886. Application filed November 13, 1885. Serial No. 182,635. (No model.)

To all whom it may concern:

Be it known that I, JUsTUs A. TRAUT, 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 Face-Plates for Marking-Gages, of which the following is a specification.

My invention relates to improvements in carpenters gages, and the object of my improvement is to provide a faceplate which when attached to an ordinary marking-gage will enable the gage to be used in working against curved edges and against beveled faces.

In the accompanying drawings, Figure l is a front elevation of my face-plate for working against curved edges. Fig. 2 is a plan view of the same. Fig. 3 is a front elevation of one of my face-plates adapted for working against curved edges and also against beveled edges. Fig. 4 is a side elevation of the same; and Fig. 5 is aperspective view of an ordinary marking-gage with my face-plate attached.

Before my invention a marking-gage was made with two round pins projecting at right angles to the gage-bar from one side of the sliding block, the front sides of which pins formed the bearing-surface of the block and adapted the device for use-in working against curved edges. Such a gage is hereby disclaimed. I form two rounded projections, a a, on a plate, A, said projections being parallel when viewed in plan view, of a semicircular form. The back side of the plate A is free from projections, so that it may be secured by screws or otherwise to the flat surface of the sliding block B of a marking-gage. These project-ions a a are adapted for working against curved edges either convex or concave, as in dicated by the curved broken lines in Fig. 2. These projections a a may be formed on a plate by themselves, as shown in Figs. 1 and 2, or in connection with the longer rounded proj ection b, which stands at right angles to the projections a a, as shown in Figs. 3, 4:, and 5. 5

face, as indicated by the broken line 0, Fig. 4.

This face-plate can readily be secured to the face of the sliding block of any ordinary marking-gage for carpenters use, and the block may be slipped upon the bar in such position as to bring either the projection b or the pr0- jections a (4 upon the same side of the gagebar as the point of the marking-pin.

The face-plate may be applied to new gages and sold with the gages, or said face plates may be sold separately for attachment to gages generally, either old or new.

Either working-face of my faceplate (the projections b or the projections a a) is adapted for working against straight and square edges the same as if the surface of the sliding block were flat.

I claim as my invention 1. As a new article of manufacture, a faceplate for markinggages, having the rounded projections to a, and adapted to be secured to the flat side of the sliding block of said gages,

substantially as described, and for the pur-.

pose specified.

2. As a new article of manufacture, a faceplate for marking-gages, having the rounded projections a a and the longer rounded projection b, the whole adapted to be secured to the flat side of the sliding block of said gages, substantially as described, and for the purpose specified.
