IMPROVEMENT lN BENCH-HOOKS.

Specification forming part of Letters Patent No. 153,524, dated July 28, 1874; application filed May 14, 1874.

To all whom it may concern Be it known that I, EDGAR B. BEACH, of West Meriden, in the county of New Haven and State-of Connecticut, have invented certain new and useful Improvements in Bench- Hooks, of which the following is a specification:

This invention has reference to a simple and effective bench-hook, which occupies a vertical mortise in a carpenters bench, and is adjustable to any required elevation to stay or hold in position the wood being planed.

My invention to such end consists of a certain combination of parts, the construction and arrangement 0t which will hereinafter be more specially descrlbed and pointed out in the claim.

In the drawings, Figure l is a perspective view of a bench-hook constructed according to my invention. Fig. 2 is a side elevation, and Fig. 3 is a central vertical section, of the same.

The letter A designates a vertical socket, which is cast or formed in one piece, with a horizontal top flange or head-plate, B, and provided with an internal cylindrical bore, into which is fitted a correspondingly-shaped bolt or post, 0. Said bolt carries at its upper end the hook or plate D, which possesses a notched edge, a, and a plain or smooth edge, I), the former to be used when rough lumber is being planed, while the plain edge is used so as not to damage nearly-finished work. The cylindrical bolt is provided with double rack or serrated surfaces E E, located, preferably, directly opposite each other, and extending from the base to near the top of the bolt.

The object of said racks is to enable the hook to be reversed to bring either the notched or plain edge in proper relation to the lumber, and to be held in either position by a single retaining mechanism applied to the receivingsocket of the hook. The top flange or headplate B of the socket A is formed with a lateral extension, F, which is cored out to form a cavity or chamber, F, for the reception of a vertically-moving plunger or stem,G, the upper end of which has a button, H, and the lower end projects beyond the cavity, and is connected to a horizontally-sliding pin or bolt, J, by a pivoted link, I. The portion of the stem or plunger G within the cavity F is encircled by a coiled spring, K, which tends to draw the stem in an upward direction, the force of the spring being transmitted to the sliding pin J by means of the link I, so as to cause the serrated or notched inner end of the dog to engage with the serrations or teeth of the movable post 0. The button H, when in its normal position, is flush with the top of the cavity F, and by depressing the same the stem will be correspondingly moved to withdraw the dog from contact with the bolt, thus enabling the same to be adjusted in a vertical direction, and be turned or reversed to suit the work to be performed.

In certain instances I may provide the lower end of the tubular socket A with an external screw-thread and shank for the reception of a fastening-nut, and a spring may also be arranged in a chamber below the base of the bolt, so as to force. the same in an upward direction when the retaining mechanism is released. a

I am aware of the patent granted to James H. Spiller, dated June 5, 1855, and I disclaim the construction of bench-dog therein described.

I claim as my invention- The head-plate B of the socket A, formed with the cavity F, in combination with the buttoned stem G, spring K, link I, and bolt 0, all constructed to operate as herein shown and described.

In testimony that I claim the foregoing I have hereunto set my hand.

EDGAR B. BEACH.
