Manufactured by Trevor & Co. - Lockport, Niagara County NY

Wilhelm & Bonner - patent attorneys This invention relates to a machine which is employed for turning heads for barrels, tubs, &c., and in which the heading is presented by a revolving clamp to a concave circular saw. A machine of this character is shown and described in United States Letters Patent No. 166,041, granted to me July 27, 1875, and the present invention is an improvement upon the same. The object of my invention is provide means whereby the saw is carried quickly across the path of the heading blank so that the latter requires only one revolution in cutting the same. I claim as my invention— 1. The combination with the movable heading clamp and the saw and its carriage, of an actuating device tending to move the saw carriage forwardly, a stop mechanism whereby the forward movement of the saw carriage is arrested before the saw has reached the cutting position and a trip device whereby the saw carriage is released when the heading too blank has reached the cutting position, substantially as set forth. 2. The combination with the heading clamp and ,the saw, both capable of movement toward and from the cutting position, of mechanism connecting the heading clamp with the saw carriage and retracting the saw carriage by the back ward movement of the clamp, an actuating device which tends to move the saw carriage to the cutting position, a stop mechanism whereby the forward movement of the saw carriage is arrested before it reaches the cutting position and a trip mechanism whereby the saw carriage is released and permitted to be moved forwardly when the clamp has moved the blank to the cutting position, substantially as set forth. 3. The combination with the main frame, the clamp frame pivoted on the main frame and the revolving heading clamp journaled on the clamp frame, of a saw having its axis arranged obliquely with reference to the axis of, the heading clamp, a sliding plate having a movement parallel with the axis of the heading clamp and adapted to carry the saw across the path of the heading blank, a rock shaft having an upper and a lower rock arm, a link connecting the upper rock arm with the sliding plate, a spring connected with the lower rock arm and adapted to move the saw into its operative position, and a retracting arm mounted on the clamp frame and adapted to engage with the lower rock arm for moving the saw into its inoperative position, substantially as set forth. 4. The combination with the clamp frame, the heading clamp mounted on said frame and the saw having a movement toward and from the heading clamp, of a spring whereby the saw is moved forward, a pawl whereby the forward movement of the saw is arrested and to a trip arm connected with the clamp frame and adapted to release the saw from the pawl, substantially as set forth. 5. The combination with the main frame, the clamp frame movably arranged in said main frame and the heading clamp mounted in said clamp frame of a sliding plate guided upon the main frame, and having a movement toward and from said clamp, a saw mounted upon said sliding plate, a ratchet connected with said sliding plate, a pawl engaging with said ratchet, and an arm attached to the clamp frame and engaging with said pawl, whereby the latter is released from said ratchet, substantially as set forth. 6. The combination with the main frame, the vertical rock shaft journaled in said frame, the clamp frame supported on said vertical shaft and the heading clamp arranged upon the clamp frame, of a sliding plate guided upon the main frame and having a movement toward and from the heading frame, a concave saw mounted on said sliding plate, a horizontal rock shaft journaled in the main frame and connected with the sliding plate, a ratchet wheel and a depending elbow lever secured to said horizontal rock shaft, a spring connecting said elbow lever with the mainframe, a pawl engaging with said ratchet wheel and provided with a trip arm, and a rock arm secured to the vertical rock shaft and engaging with the elbow lever and trip arm, substantially as set forth.

Another of the classic patent gages. An extremely elegant design, in which an H-shaped bar holds two independent heads. This simple design allows a single compact gage to hold two distinct settings. This gage was produced for many years, in several variants. The earliest versions used a plain rosewood or boxwood bar, which caused wear problems because the locking screws bit into the wooden bar. Later models added an inlaid brass strip to provide a more solid wearing point for the screw. Also late in production, these were offered with a brass sliding bar on one side, allowing it to be used for marking mortises.
