CLAMP.

SPECIFICATION forming part of Letters Patent No. 523,974, dated August 7, 1894.

Application tiled July 25,1893.

T a/ZZ whom it may concern: l

Be itknown that I, ANDREW J. ,COURTNEY, of Pme Ridge, in the countyof Fresno and State ot' California, have invented anew and usefullmprovement in Clamps, of which the ollowlng is a full, clear, and exact descripion.

My invention relates to an improvement in clamps, and, has for its object especially to provide a clamp adapted for bundling and maintaining in bundled form timber of any description, whereby timber may be handled much more expeditiously-and economically than it is possible when each piece of timber tire device.

is independent of the other, and whereby also I1n shipping timber, jams are not so liable to occur.

The invention'consists in the novel construct1on and combination of the several parts as w1ll be hereinafter fully set forth, and pointed out in the claims.

Reference isto be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of 4the device, showing it in the act of being applied. Fig. 2 is a side elevation of the device in the position shown in Fig. 1. Fig. 3 is a partial side elevation and partial-sectional View of the device, illustrating it in` its applied or clamping position; and Fig.4 is an innerface View of the device proper.

In carrying out the invention the clamp proper comprises two sections A and B, in connection with which a lever C is employed, the two parts constituting essentially the en- The sections A and B of the main or body portion of the device consist each of a bar 10, which at one end terminates in a hook 11; and the inner end of the section A, is provided with a shoulder 12 near its inner end, which shoulder extends beyond opposite faces of the rod orbar 10; and at the extremity of the section A a stud 13, is formed, which stands at right angles to the rod and faces inwardly or in the same direction as the hook 11. The body rod 10 of the other section B, is provided with a shoulder 14, near Seria-l No. 481,394. (No model.)

its inner end, corresponding to the shoulder 12 of the section A; and the body rod of the section B, continues of the same width from the shoulder to its inner end, and in the wider portion of the section, between the inner end and the shoulder 14, an aperture 15, is produced, adapted to receive the stud 13 of the section A, and a channel or recess 16, is produced in the wider portion ot the section B, upon its outer face and extends from its inner end to the aperture 15.

The lever C, comprises a handle member 17, which at one .end is bifurcated to form twin claws 18; and near the twin claws18 of the handle member an arm 19, is pivoted at one end to the said member of the lever, and

the outer or free end of this arm is bifurcated and provided with twin claws 20, adapted to face those upon the handle member of the lever, as shown in both Figs. 1 and 2.

In operation, the device may be applied to the sides of a bundle or pile of timber, or to the ends, or to both the sides and ends; and in making the application the hook of one section of the main portion of the device is made to engage with the outer surface of the top board of a pile, while the hook of the other section engages with the under face of the undermost board.- When so engaging the stud 13 of-the section A will or should rest upon the channeled surface 16 of the section B. The lever is now applied, the claws 20 of the arms 19, for example, being made to engage with the shoulder 12 of the section A, whilethe claws 18 of the handle member of the lever will be brought in engagement with the shoulder 14 of the section B. By4

pressing downward upon the handle of the lever the two sections A and'B, will be carried at their inner ends in direction of each other, their hook members sinking into the.

IOO

lever C is removed and is applied to other sections to place them likewise in position.

The clamp is exceedingly simple, it is durable and it is economic, and it is capable of being readily manipulated by any person of ordinary intelligence.

Having thus described my invention, I claim as new and desire to secure by Letters Patent y 1. In a lumber clamp consisting of two sections, the combination, with one section comprising a broad body, a clamping hook integral with one end of said body near the center thereof, whereby a shoulder is formed at each side of the hook, and a stud projected at an angle from the opposite end of the body, facing in direction of the curved portion of the hook, of a second member comprisinga broad body having a channel produced in one l face, and an aperture at the inner end of the channel, a hook the shank of which constitutes an integral portion of the body near the center, forming thereby a shoulder at each` side of the shank, the hooks of the two sec-` tions being adapted to face in the same direcy tion and face one another, the stud of one section being adapted to enter the aperture of the other section guided thereto by the said channel, substantially as shown and described.

2. In a lumber clamp, the combination, with guide leading to the aperture, and ahook the shank. of which is integral with one end of the body, a shoulder being formed at each side of the hook shank, the said two sections being adapted to stand body to body, the hooks facing in the same direction and facing each other, of a compression device, the same con sisting of a lever terminating at one end in a claw adapted for engagement with the shouldered portion of one section of the clamp, and an arm pivoted to the lever, said arm terminating in a claw adapted foren gagement with the shouldered portion of the other clamping section, whereby when the lever is moved in one direction the clamping sections are drawn together, and the stud of one section ismade to enter the aperture in the other section, as and for the purpose set forth.
