DAVID J. DUANE, OF VINAL HAVEN, MAINE.
SLIDING GAGE FOR STONE-CUTTERS USE.
SPECIFICATION forming part of Letters Patent No. 459,679, dated September 15, 1891.
Application filed April 1, 1891. Serial No. 387,237. (No model.)
To aZZ whom it may concern;
Be it known that I, DAVID J. DOANE, of Vinal Haven, in the county of Knox and State of Maine, have invented a new and useful Sliding Gage for Stone-Cutters Use, of which the following is a full, clear, and exact description.
The objects of this invention are to provide a simple, practical, and convenient attachment for a stone-cutters square which will afford means to gage the depth of a projecting shoulder, bead, or other member that is in progress of formation upon a slab or block of stone, and also to determine the parallelism of such members or of the sides of the block or slab operated'upon.
To these ends my invention consists in the construction of parts and their combination, as is hereinafter described and claimed.
Reference is to be had to the accompanying drawings, formingapartof this specification, in which similar letters of reference indicate corresponding parts in the views shown.
Figure 1 is a perspective View of the device in position ona square, the implement and square being shown broken away at one end of each to. reduce length in the illustration; and Fig. 2 shows the gage on a square applied to a dressed bl ck of stone, indicating its use.
The implement consists, essentially, of a gage-rod A, of a desired length necessary for efficient service, having alimb A formed on one end at a right angle thereto, the rod and limb being preferably made square in crosssection. On the rod portion A graduations are provided to facilitate measurement of work in progress of execution.
The remaining portion of the gage consists of a sliding head B, formed from a metal bar which is bent right angular at a and I), thus affording a leg B of the same length as the limb A, and a shorter lug c at a suitable dis tance from the leg mentioned. The spacingbar (I, which extends between the leg 13 and lug c, is centrally apertured in a plane aligning with and parallel to a center line extending longitudinally of the leg B and lug c, which aperture is threaded to receive a thumbscrew 6, that is of a sufficientlength to extend through the spacing-bar. Aligning rectangular holes are formed in the leg B and lug 0 parallel with the spacing-bard and near to it, which holes are of such relative and similar dimensions as will permit the gagerod A to slide therein without looseness, the space between said rod and the spacing-bar (I being such as will allow the blade of a common metal square C to slide therein, as shown in Fig. 1.
In service, it it is desired to ascertain the depth or drop of a shoulder. as at g, from the top face of a stone block E, the square C is applied to the block so as to project the blade whereon the gage is placed across the upper surface of the block anti resting on said top face h. The gage-rod A is now adjusted to have a close contact with the shoulder or other projection g of a dressed stone, the distance of which from the upper surface it will be indicated on the gage-rod where the edge of the square-blade that engages the stone crosses the graduations on the upright gagerod. If it is desired to caliper the thickness of a block, slab, or column of stone while itis being formed to test its approach to the de sired size or to ascertain it' two opposite faces are parallel, the limb A and leg B are set the correct distance apart, when their application in an obvious manner will indicate the condition of the work and where it must be altered to correct defects, if any exist.
Having thus described my inventi0n,I claim as new and desire to secure by Letters Patent 1. A gage for stone-cutters, consisting of a gage-rod which is provided with a laterallybent limb at :d right angle thereto and is graduated as a measure of length 011 one side, and a sliding head provided with a leg, and a lug bent in the same direction from the end portions of a spacing-bar, said leg and} lug having aligning apertures for the sliding connection of the gage-rod, and a set screw penetrating the spacing-bar between the legand lug, substantially as described.
2. In a stone-cutters gage, the combination, with agage-rod having a limb turned at a right angle on one end and graduated on one side as a measure of length, of a sliding head havinga leg and a lug formed on the [between the spacing-bar and the inserted same side of an intervening spacing-bar and gage-rod, substantially as described. each apertm'ed to receive the gagei'cd and DAVID J DUANE allow it to slide parallel with the spacing-bar, 5 and a setserew in said bar which will project; \Vitnesses:
between the leg and lug 011 said bar and im- DANIEL H. GLIDDEN, pinge on a square-blade that may be inserted EDMUND V. AREY.
