EDWARD A. WALKER, OF NEW HAVEN, CONNECTICUT.
IMPROVEMENT IN JOINERS CLAMPS.
Specification forming part of Letters Patent No. 14034.7, dated July 8, 1873; application filed March 26, 1873. I
To all whom it may concern:
Be it known that I, EDWARD A. WALKER, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Joiners Clamp; and I do hereby declare the following, when taken in connection with the accompanying drawin gs and the letters of reference marked there on, to be a full, clear, and exact description forming the beam with a channeled or recessed side, and in the said channel a series of teeth or notches combined with a spring-pawl in the side of the movable arm, the said pawl serving to set the arm to any desired point.
A is the beam, formed with a head, B, thereon, in substantially the usual manner. This beam has a longitudinal recess or channel, a, formed on its side, and over the beam is set the arm 0, fitting closely to the beam, but yet so as to allow the arm to move freely thereon. The arm 0 is provided with the usual set-screw D, in line with the head B. In the channel a on the beam a series of notches, d, are formed,
more or less in number, and into the arm immediately over these notches a pawl, b, is placed, pivoted as at c, with a head, F, projecting slightly from the arm, and beneath the head a spring, f, is arranged, the tendency of which is to throw down the nose of the pawl. The pawl is raised by depressing the head, as
denoted in broken lines, Fig. 4.. This is conveniently done by the operators thumb, and when the pawl is so raised the arm may be moved to any desirable point, and then dropping will hold the arm.
I do not wish to be understood as broadly claiming a joiners clamp having the arm made adjustable by means of a. series of teeth on the beam, as such, I am aware, is not new. My invention possesses this advantage over previous construction, that the adjusting devicethat is, the notches or teeth-is not exposed, but is protected by the projecting edges, which form the channel on the side of the beam.
, I claim as my invention As an article of manufacture, the herein-described joiners clamp, consisting of the beam A with its head B, and the arm 0 with its screw D, the beam constructed with a channel, a, on its side, and a series of notches, d, combined with the pawl I), head F, and spring f, all constructed and arranged substantially as described.
