SPECIFICATION forming part of' Letters Patent No. 404,368, dated May 28, 1889.
Application filed June 9, 1888. Serial No. 276,581. (No model.) i
To all whom it may concern:
Be it known that I, EDWARD O. STEARNS, of
Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Clamps, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention relates to an improvement in clamps; and it consists in certain peculiarities of the construction and arrangement of the same, substantially as will be hereinafter more fully set forth and claimed.
In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe its construction and operation, referring to the accompanying drawings, in which Figure 1 is a side elevation of my clamp. Fig. 2 is a longitudinal section of the same. Fig. 3 is a cross-section on the line 50 :20, Fig. 2 and-Fig. 4 is a similar view on the liney 3 same figure.
a represents a bar of any suitable size and material, having its lower side formed with a series of transverse notches, a, and a longitudinal groove, a formed in its upper face, as clearly shown in the drawings.
1) is one of the movable clamp-heads, having its clamp-face at right angles to the bar and extended somewhat in the rear to give a firm support. This head I) is formed with a forwardly and downwardly extending loop, I), rigidly secured thereto, which surrounds the main bar a, and, as clearly shown in Fig. 2, the lower bar of this loop is formed to fit any one of the notches a in the under face of the main bar. A spring, 12 is interposed between the head Z) and the bar a, and its end extends forward and lies in the groove a of the bar a. This spring holds the head in the position where it may be placed, and it cannot accidentally become displaced, as by reason of its peculiar position contact therewith is obviated. When it is desired to move the head, its upper end-is pressed forward against the spring, and the bar of the loop is drawn out of the notch, when the head is readily slid along to any point desired.
0 is a second and stationary head, formed with an extending loop for surrounding the bar, exactly as described for the head 1). Through this head 0 passes a screw, 0, on the end of which is secured a follower, c closely fitting the bar a. The head c is also remov- 5 5 able from the bar a, but, as preferably formed, is not adapted to be moved longitudinally thereon, since at its adjacent extremity of the bar there is only one notch, a, as seen in Fig. 2, for engaging the projecting loop formed integral with said head. At a point near the top of the-bar a, I provide the pin a projecting therefrom and abutting against the back side of the said projecting loop, for the purpose of retaining the head 0 in position on the bar a.
The follower 0 as best shown in section in Fig. 2, is mounted upon the rounded extremity c of the screw 0, and engages the same by a rounding socket, 0 provided on the follower and open at the top to admit of the ready insertion of the said extremity 0 when assembling the parts. WVhen the parts are in their operative position, the socket c is prevented from becoming disengaged from the extremity c by means of the raised projection 0 on the opposite side of the socket. to the face of the follower. \Vhen the head 0 is disengaged from the bar, it will be seen that the follower may be readily withdrawn So from or inserted upon the extremity c by reason of the socket being open at the top thereof.
In use for cabinet-making, carpentry, or any other suitable work, the movable head I) is first adjusted to the notch nearest to the size of the work to be clamped, and, the work being placed in position, the follower c is screwed up and the work is firmly held. The head Z7 is readily moved, as explained, but 0 cannot be accidentally displaced, and it will be noted that by its peculiar form the greater the pressure upon its face the more firmly it is held in position.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination, with the bar a, formed with a longitudinal groove in its upper face and having its lower face formed with a se- ICO ries of transverse notches, of the movable head I), having a forwardly-inelined loop rigidly secured thereto for embracing the bar and engaging the notches, the spring b and the stationary head 0, its screw c, and follower 0 all constructed and arranged to operate substantially as and for the purpose set forth.
2. The combination, with the bar a,having its lower face formed with a series of transverse notches, the movable head 11, having a forwardly-inelined loop rigidly secured thereto for embracing the bar and engaging the notches, a spring for forcing the loop to engage the transverse notches, the head 0, hav- EDWARD C. STEARNS.
