VALVE-SPRING LIFTER. I

Specification of Letters Patent. Patented Sept. 28, 1920.

Application filed June 14,1919. Serial No. 304,227.

T 0 all to hom "it may concern:

Be it known that I, J OHN B. MEILER, a citizen of Switzerland, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Valve-Spring Lifters, of which the following is a specification.

This invention relates to valve spring lifters and has for its primary object the provision of a tool of this class which is designed for use in compressing the spring to release its pressure from the valve and permit the latter to be readily lifted when it is desired to re-grind the faces of the seat or valve.

Other objects of the invention are to provide a tool of this character which will be simple of construction, strong and durable and capable of being quickly connected with ordisconnected from the work as the occasion necessitates, and one which will be substantially universally adjustable to suit many varying conditions.

lVith the above and other objects in view which will appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangements of parts which will hereinafter be fully described and particularly pointed out in the claims.

In the accompanying drawings, has been illustrated, a single and preferred form of the invention, it being, however, understood that no limitations are necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

Figure 1 is a side view of the tool showing the same applied in the act of lifting the valve from its seat.

Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1 with parts in full lines.'

Fig. 3 is a section on line 3-3 of Fig. 1.

The tool comprises mating levers 5 and 6 which in this instance are arranged superposed. The lever 5 is provided with a post 7 having a stem 8 arrangedto turn in said lever and as illustrated the said stem is upset at 9 against the lever. The companion lever 6 is provided with a swinging cylindrical socket member or sleeve 10 which is slidable on the post 7. This arrangement provides for changing the leverage as the occasion demands as the two levers are free to be adjusted relatively. In order that any required adjustment of the levers can be retained, it is preferred that the post 7 be provided with a longitudinal series of passages 11 which are arranged to register with similar threaded passages 12 formed in the socket member 10. A pin 18 is adapted to be passed through the registering passages 11 and 12 and connected there with in a manner which will hold the post and the receiving socket member against sliding movement.

The forward end of the lever 6 is pro vided with angularly disposed guide surfaces 14 and in the immediate proximity of said surfaces the lever is cupped at 15 to accommodate the washer 16 of the valve stem. The mating lever 5 has its forward extremity provided with similar angularly disposed surfaces 17 and said lever is provided with a cupped portion 18 which is adapted to conform with the cam shaft plunger collar. By providing the angular surfaces 1l1land 17-17, it will be observed that the levers can be quickly guided into position, while through the arrangement of the cupped portions 15 and 18 it will be manifest that when the levers are once positioned relatively of the valve they can be maintained in such positions without fear of casual dislodgment. Through the fact that the post 7 is free to rotate it follows that the lever 6 is adapted to turn in a horizontal direction whereby the lever can be accurately associated with the valve stem irrespective of whether or not the forward extremity of the lever 5 is in exact vertical alinement with the forward extremity of the lever 6. The said forward ends of the levers 5 and 6 are uniformly bifurcated, as shown, and in view of the described manner of connecting said levers, it follows that they can be rocked and also shifted laterally to cause the arms of said bifurcated ends to be relatively straddled or arranged side by side in the same horizontal alinement. This connection of the parts permits the size of the lifting part of the tool to be materially reduced, which, when taken in connection with the surfaces 1414 and 1717 enables the operator to conveniently guide the tool in position with the valve structure.

The operating ends of the levers are provided with suitable hand grips l9 and as shown a chain is suspended from one of said grips and the links thereof are adapted to be interchangeably connected with a hook 21 on the grip of the other lever. In this manner it will be observed that if the valve has been lifted and the spring compressed the levers can be held in relatively fixed positions and the valve maintained'in an elevated position above its seat where the former and the latter will be exposed to permit them to be reground.

What is claimed as new is 1. A valve spring lifter comprising a pair of levers, a post rotatabl'y supported from one of said levers, a socket member slidable over said post and supporting the other lever for rocking movement, the said post serving to permit said other lever to be rotated in a horizontal direction, and

means for holding the socket member fixed to the post.

2. A valve spring lifter comprising a pair of levers, a post rotatably supported from one of said levers, a socket member slidable over said post and supporting the other ble connection with the other lever, to hold both levers in their set positions of adjustment.

3. A valve spring lifter comprising mating levers, said levers having bifurcated forward ends in which the arms of said hifurcations are provided with cupped portions, the cupped portion of the arms of one lever being reversely positioned with respect to the cupped portions of the arms of the other lever, and means operatively connecting said levers for vertical and horizontal swinging movements to permit the levers to be'relatively separated and to also permit the arms of both of said bifurcations to be relatively straddled when the levers are adjusted for initial application to the valve.

In testimony whereof I have aflixed my signature.

JOHN B. MEILER.
