set screws 33 to prevent displacement.

Operation The gauge is placed upon the top of the block of stone andthe handle I9 is moved outwardly against the pressure of the spring l5 for a slightJ distance, and the movable jaw I2 isv moved against the side of the stone until the plug 25 touches the same. The handle I9 is now released and the spring I6 will move the movable jaw i2 vagainst the block of stone and 'at thev same time swing the pressure member 23 of the movable jaw l2 slightly on its pivot 24 until the cam 36 limits further swinging movement, clamping the movable jaw I2 firmly in position on the bar I0. l

The gauge now .being clamped in position, the stone cutter may chip the edge as desired or he may manipulate the letter spacing rule, as above described. Torelease the gauge it is merely necessary Yto move the handlelS away from the stone to release the jaw Il from engagement therewith. The gauge may now be removed byy lifting the handle of the jaw Il, with the bar IEB connected thereto, so as'to pivot for an instant on plug 25 of the movable jaw.

means operative when the slidable jaw is moved against the side of the block of stone for clamping theslidable jaw `on the bar, and means forr moving ,Y the springA pressed jaw against Vthe the stone to release the gauge therefrom.

2. A stone cutters gauge comprising a flat bar, a jaw slidably mounted on the bar foren'- gaging one side of a block of stone, and a spring pressed jaw for engaging the opposite side, said slidable jaw comprising a bracket slidable on the upper face of the bar, a pressure member pivoted to the bracket and depending therefrom, and means for clamping the bar and bracket together, and manually operated means for movr and a cam fastened to the pressure member and adapted to clamp the bar and the bracket together, said spring pressed jaw including a second pressuremember depending from the bar, a spring tending to move the second pressure member toward the side of the stone, yand a handle for moving the second pressure member against the tension of the spring and away from the stone.V

4. A stone cutters gauge comprising a iiat bar, a jaw slidably mounted on the bar for engaging one side of a block of stone, a spring pressed jaw for engaging the Vopposite side, said spring pressed jaw including aY pressure member depending from the bar, and a handle connected to the .pressure member and extending above the bar, said handle and pressure memberv being mounted for limited slidable movement along the bar, and means limiting the movement of the pressure member toward the side of the stone.

5. A stone' cutters gauge comprising aat bar, a jaw slidably mounted on the bar for engaging one side of a block of stone, and a spring pressed jaw for engaging the opposite side, said slidable jaw including a bracket slidable on the upper face of the bar, a pressure member pivoted to the bracket and depending therefrom, said pressure member having a cam adapted to engage the under side of the bar for clamping the bar' and the bracket together, said` spring pressed jaw including a second Vpressure member depending from the bar and a handle integral therewith extending above the bar and pro- Y wardly to form a spring seat, a coiled spring mounted between the spring seat and the second pressure member, a bolt passing through the spring seat and secured to the second pressure member, and a nut on the bolt for adjusting the tension of the spring.
