Abstract
21,759. Haggas, J. H. Sept. 23. Cramps; holding- tools. - A device for compressing springs, more particularly springs for exhaust and inlet valves of internal-combustion engines to facilitate handling when inserting them in place, comprises a rod B which is formed at one end with a screwed adjustable member E' adapted to bear against one end of the 'spring G and is connected at its other end to a wedge-like member, such as the cam A, which is provided with a handle A<1> and bears against the other end of the spring. Rotation of the cam effects the compression, and the spring may be locked in a compressed condition by clips I, I', Fig. 5. A bearer F may be provided between the spring and cam, and may have rollers H<2>, H<3> which engage a notch A<2> and flat A<3> on the cam when the spring is compressed. The cam may be replaced by a toggle - lever which takes the form of an L-shaped lever, the short arm of which bears against the bearer F, and is pivoted to the rod B; the longer arm extends approximately perpendicular to the bearer F, and is rocked to compress the spring.
