SPRING APPLIER AND REMOVER. APPLICATION FILED APR.2I. I9I9.

1,342,529. Patented June 8, 1920 avwwtoz UNITED SPRING APPLIER AND REMOVER.

Specification of Letters Patent.

Patented June 8, 1920.

Application filed April 21, 1919. Serial No. 291,627.

To all whom it may concern:

Be it known that I, GEORGE J. CHARLAND, a citizen of the United States, residing at Sandpoint, in the county of Bonner and State of Idaho, have invented certain new and useful Improvements in Spring Appliers and Removers, of which the following is a specification.

The present invention relates to improvements in spring appliers and removers, designed especially for use in connection with springs of tappet and similar valves, wherein the spring is to be compressed preparatory to removal from or application to the stem of the valve, purpose of holding the spring pressed while the cotter pin is being removed when applying and to hold the spring in line when being applied.

The primary provision of a object of the invention is the device of this character by means of which the spring may be held in alinement in order to facilitate the application to and the removal from its seat of the spring and prevent accidental displacement of the spring.

To this end the invention contemplates the use of a pair of parallel levers carrying the clasping members or jaws for the spring,

combined with means for removing the,

levers toward or away from each other for compressing the spring or to permit it to expand, the levers being maintained at all times parallel with each other and the clasping jaws and levers moving in the same parallel planes in axial alinement with the stem of the valve and its spring, thus holding the spring in axial alinement with the stem and preventing the spring from buckling and becoming displaced.

The invention consists in certain novel combinations and arrangements of these parallel levers and their jaws in connection with means for actuating the levers and maintaining them in parallelism as will be described.

In the accompanying drawings 1 have illustrated one complete example of the physical embodiment of my invention, the parts being combined and arranged according to the best mode I have so far devised for the practical application of the principles of my invention.

and particularly for the Figure 1 is a side view in elevation of the tool embodying the invention, showing it 1n position of actual use, compressing the spring on the stem.

Fig. 2 is a top plan view of the tool of Fig. l.

Fig. 3 is an end view of the tool, showing particularly the pivoted hooked jaws on the pivoted head of the tool adapting the tool for use with different springs.

In the preferred embodiment of the invention as depicted in the drawings, I utilize a pair of levers 1 and 2 that are of metal and of suitable size and shape, and these levers are normally and at -all times in parallelism, and actuated through the instrumentality of the screw bar 3.

The screw bar is provided with both right hand threads and left hand threads and is turned by a hand wheel 4:, but remains seated in the intermediate, fixed, connecting bar 5 which is provided with a slotted journal 6 for the screw bar to turn in. The relationship of the two levers and the intermediate bar is one of permanent parallelism, although of course the distance between the two levers and the intermediate bar is changed by turning the screw bar when the spring 20 is to be compressed; or permitted to expand.

At one end, the levers are connected to the intermediate bar by a pair of links 7, 7 having acommon pivot 8 on the intermediate bar, and pivoted at 9, 9, to the ends of the levers, while at the opposite end of the tool a pair of links 10, 10 are provided with a common pivot at 1.1 on the intermediate bar and pivots 12 12 on the levers. The links 7 and 10 are arranged in parallel pairs to swing on their pivots as the screw bar is turned and to'maintain the levers in stable and fixed parallelism.

One of the levers, at its free end has an extension or forked end 13 with the open slot 14, forming a fixed clasping jaw for the spring, and cooperating with this fixed jaw,

' with the stem 19 of the valve,

permits an oscillating movement of the head transversely of the'lever, while the jaws, which are pivoted at 18 to the head, project beyond the head with their hooked ends turned toward each other, and may oscillate on their pivots 18.

Thus the pivoted head 17 enables thetool to be applied, and with facility, to any ordinary angle of spring, and the two pivoted jaws 15 adapt the device for different sizes of springs.

The operation of the tool is illustrated in Fig. 1 where the spring 20 is associated and the cup 21 forms the seat for the spring, the upper end of the spring being retained as usual by the cotter pinof the valve stem.

The forked end or fixed jaw of the tool is slipped under the cup 21 and around the stem, and'the two-hooked jaws 15 are turned on their pivotsso that their hooks engage over the upper end of the'spring. Now by turning-the hand wheel 4', its right and left hand screws bring the two levers toward each other, the links maintaining the levers in stable parallelism and. the spring is compressed between the flexible jaw and the fixed jaw of the tool, thefiexible jaw adapting itself to the spring and clasping the spring with a secure and firm hold; while the fixed jaw forms a rigid seat for the lower end'ofthe spring. In this manner the spring may be compressed for application to or removal fromthevalve devices, without danger of displacement or disarrangement, and' without harm to the operator.

What I claim is- 1. The combination'with the pair of parallel levers, an intermediate fixed connecting bar, and links pivoted between said levers and the bar, of a transverse screw bar operable in the fixed bar having right and left hand threads in the levers, and clasping jaws on the levers.

2; The combination with the pair of parallel levers, the intermediate bar, and the connecting'linlrs, of a transverse screw bar operablein the intermediatebar and having right and left hand threads in the levers, and spring, clasping means on the levers, one of which is fixed and the other flexible with relation tothelevers.

3. The combination. with the levers, links, intermediate bar and screw bar, of a fixed jaw on one lever, and a flexible jaw on the other lever comprising a pivotedhead' on the lever and apair of pivotedIco-acting hooked members, as described.

4. The combination with thelevers, intermediate bar, screw bar, and links, of a fixed slotted jaw on one lever, a transversely pivoted head on the other lever, and a pair of outwardly projecting jawspivoted at the sides of'the fulcrum of the head andhaving inturned hooks, as described.

In testimony whereof: I afiix my signature.
