OKEY STANLEY 'MQFABLAND, OF OYSTER BAY, NEW YORK.
TOOL FOR VALVE-SPRINGS.-
fication. A I i Theobject of the invention is to provide a simple and convenient tool whereby the stiff springs of gas engine valves may be readily compressed preparatory to assembling them withthe valves.
The invention accordingly comprises certain combinations of parts,,which will now be described and be hereinafter more par-;
ticularly pointed out in the claims.-
In the accompanying drawings forming a part hereof:
Figure 1 1s a side elevation of the device in positio n to compress a spring; Fig. 2 is an end/ elevation of the same;.Fig. 3 is a view similar to Fig. 1, showing the spring compressed by the tool; Fig. 44 is a vertical sectional view of an engine cylinder, with the valve and spring in elevation, showing the hooks for holding the spring compressgd until after the parts are assembled; and Fig. 5 is a perspective view of one of the hooks.
vThe device is provided with means for fixing it firmly in ppsition on a table or bench, the said means comprising a table clamp member or yoke\ 2 having a clamping screw 3.
A fixed jaw 4 is formed on the table clamp member and projects npward therefrom. With it coiiperates a movable jaw 5, which is formed on the end of a horizontal bar 6,
which slides through a guide opening 1nthe table clamp member beneath the fixed jaw. As shown'in Figs. '1 and 2 this bar projects to a. considerable distance.
A hand lever 7 is fulcrumed at 8 on the table clamp member, at apoint intermediate the ends of the bar 6, with which it is connected by a rigid thrust link 9,, the connection of the said link with the bar being at the opposite side f thetable clamp member from thejaws. The lever and link thus form a toggle, which is straightened in order to compress the spring, as represented in Fig. 3'. In this way great power is available, and the device is self-holding when the pivots 8 a line of 10 and'll are brought into or past centers. A projectingpin or abut- Specification of Letters Patent.

Application filed August 7, 1915. Serial No. 44,221.
Means are provided whereby the pivoted ends of the link may be set at various points along the lever 7 and bar 6. To this end screw clamps 12 and 13 are mounted so as to be capable of being fixed at any points along these members, and it is to these clamps that the ends of the link, are directly pivoted.
The range of. movement of the movable jaw 5 may be varied, thus varying the compression of the spring, by setting the clamp 12 nearer to or farther from the fulcrum 8. This changes the leverage. By sliding the bar 6 through the clamp 13 the movable aw may be initially set nearer to or farther from the fixed jaw, thus varying the spread of the jaws to receive springs of different lengths. By the combination of adjustments thus made possible the tool may be adapted for anyone of a. large number of sizes of springs and for any desired degree of compression. 1
When a spring is compressed it is held by a couple of double-ended hooks 14 as shown in Fig. 4:. In this condition the spring may be safely removed from the compressing device and placed in position on the valve stem, where it is confined in the usual way.
What I claim as new is:
1. A spring compressing tool, comprising, in combination, a clamp member, a fixed jaw thereon, a movable jaw slidably mounted on the clamp member, said jaws adapted to receive a spring between them, a hand lever fulcrumed on the clamp member, a rigid link pivoted to the hand lever and slidable jaw, and means for adjusting one end of saidlink along said hand lever.
2. A spring compressing tool, comprising, in combination, a clamp member, a. fixed jaw thereon, a movable jaw slidably mounted on the clamp member, said jaws adapted to re.- ceive a spring between them, a hand lever fulcrumed on the clamp member, a rigid link pivoted to the slidable'jaw and to the hand lever, the end of the link connected to the hand lever being adjustable longitudinally of the hand lever.
3. A spring compressing tool, comprising in combination, a table clamp member beaiiing a fixed jaw, a. bar slidable horizontally through said member and bearing an opposing jaw, said jaws adapted to receive a spring between them, a hand lever fulcrumed on said clamp-member intermediate the ends of said'slidable bar a rigid thrust link pivoted to said lever and to 'said bar,
4 the connection of the link With the bar be ing at the opposite side of the lever from the 10 jaws, and means for setting the. pivotal ends of the link at various points along the lever and'slidable jaw.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnessesf OKEY STANLEY MGFARLAND.
