HEINRICH GGLKEL, OF NEUNKIROHEN, GERMANY.
CLAMPING DEVICE FOR WORK BENCHES.
SPECIFICATION forming part of Letters Patent No. 697,475, dated ApriI 15, 1902.
Application filed December 18, 1901. Serial No. 86,369. (No model.)
To all whom it may concern:
Be it known that I, HEINRICH GoLKEL, a subject of the German Emperor, and a resident of Neunkirchen, Germany, have invented certain new and useful Improvements in ed.- The-accompanying drawings illustrate one practical construction thereof.
Figure 1 is a front elevation of the clamping device. Fig. 2 is a section on the line y g of Fig. 1. Figs. 3 and 4 are sections on the line mm of Fig. 1. The first of these figures shows the clamping device at rest, and the last figure shows the device in operation.
In the frame a, which is arranged in a suitable manner on the work-bench, there is provided a jaw or a clamping-bar c, which is capable of movement and has a little play. In order to guide it, there'are employed bars d, of which the central one is provided with a regulating-screw e, that serves to fix a coiled spring f. The other end of this spring, which is in tension, is bent over in the form of an eye and fits on a crank-pin g, of which the axle it can rotate in the bearing 7; of two wooden cross-pieces. which projects beyond the frame is bent over in a rectangular manner and forms a handle is.
In order to prevent the crank in its rotation from one dead-center to the other dead-center, as shown in Figs. 3 and 4, from making a complete revolution, a recess l is provided in one of the cross-pieces, and in this recess the crank will enter, while its pin will, notwith- The end of this axle standing, remain free. On the inner side this recess is or may be just deep enough to allow the crank to reach itsdead-center; but on the outer side it is made slightly deeper, so that the crank may just pass the dead-center and then be positively stopped against the bottom of the recess, thus establishinga lock against the tension of the spring.
The manner of operation of this device will be readily understood. When, for instance, it isdesired to clamp the piece m, the said piece is placed between the parts a and c, the spring being strained, then the handle is is turned through one hundred and eighty degrees orslightly over to pass the outer deadcenter, as above explained, whereby the jaw c is forced against the parts m and a by the pull of the spring. The release of the clamped work is produced by moving the handle is in the reverse direction, as will be readily understood.
Having now fully described myiuvention, what I claim, and desire to secure by Letters Patent, is
A clamping device for work-benches, comprising a jaw of clamping-bar 'c' guided in a frame fixed to the bench in a suitable man ner, a crank-shaft h mounted in the frame and by which the jaw may be moved, the crank-pin being connected to the movable jaw by means of the coiled spring f which is secured to the guiding-bar by regulatingscrew e, a handle for throwing the crank from one dead-center to the other and a stop'for said crank slightly past the outer dead-center.
In testimony whereof I have hereunto set my hand in presence of two witnesses.
HEINRICH GOLKEL.

CARL SCHMITT, CHARLES LE SIMPLE.
