UNM'E LtiZBJliG CHARLES ELLIS NEWSON, OF SALT LAKE CITY, UTAH.

VALVE LIFTER.

Application filed July 11,

To all whom it may concern.

Be it known that I, CHARLES ELLIS NEW son, a citizen of the United States, and a resident of Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Valve Lifters, of which the following is a specification.

This invention relates to valve lifters and has for its object the provision of a device adapted to be so adjusted whereby the same may be applied to springs of various widths and lengths.

A further object of the invention is the provision of a device having a plurality of adjustments and capable of being locked in position for maintaining the valve in position after the same has been lifted.

This invention will be best understood from a consideration of the following detailed description in view of the accon'iipanying drawing forming a p art of the specification nevertheless it is to be understood that the invention is not confined to the disclosure being susceptible of such changes and modifications, which shall define no material departure from the salient features of the invention as expressed in appended claims.

In the drawings:

Figure 1 is a view in perspective of the valve spring lifter locked in open position.

Figure 2 is a side view of the lifter in closed position.

Figure 3 is a side view of the lifter locked in open position.

Figure 4 is a side view of the lifter adjusted for action upon long springs.

Figure 5 is a side view of the lifter in open position and vertically adjusted for acting upon long springs.

Figure 6 is a transverse vertical section of the lifter showing the vertical adjustments for the same.

Referring more particularly to the drawing. a fulcruming fork is provided having a handle 1 and a pair of adjustable jaws 2- and 3 forming a fork 4. Adjacent the fork 4 are two upstanding and integrally formed arms 5 which are perforated in spaced relation and adapted to receive bolts forming a pivotal mounting for the inner end of a second for; 6. This fork is likewise provided with a pair of adjustable jaws 2 and 3 similar to the aws of fork 4.

Each of the forks is split as shown at? and a threaded passage formed laterally through 1923. Serial No. 650,898.

one side of the jaw 3 is adapted to receive a threaded adjusting bolt 8 which when screwed inwardly will force the jaws apart. The lateral adjustn'ient of the jaws permits the valve lifter to be employed in connection with larger springs.

The alined perforations formed intermediate the ends of the arms 5 are adapted to ordinarily receive a bolt 10 which passes through the inner end 11 of the fork 6 for supporting said fork in its lowermost posi tion as disclosed more fully in Figure 2. The upper surface of the-end 11 oft-he fork 6 is disposed horizontally when the forks are in engaged posit-ion while the shank 12 of this fork is inclined downwardly at an angle to the horizontal position of the fork.

A lever 13 pivoted adjacent its inner end on a bolt 14 has an inwardly projecting end 15 disposed beneath the end 11 of the fork 6. The bolt 14 normally is located in the alined perforations 16 in the arms 5.

The inner end 15 of the lever 13 is connected by links 17 to the shank 12 of the fork 6 and adjacent its pivotal connection on the upper ends of the arms 5.- The alined perforations 19 in the arms 5 are adapted to receive the bolt 10 as shown in Figure 6 and pivot the inner end of the fork 6 at a higher elevation than is disclosed in Fig ures 1 to 8 inclusive, while the inner end of the lever 13 is pivoted on the bolt 14 in the intermediately disposed perforations. When it is desired to vertically adjust the inner end of the fork 6 and the lever 13 along the arms 5. the bolts 10 and 14 are removed from the perforations as shown in Figures 1 to 3 and the fork 6 and lever 13 are raised as a unit until the passages in the fork 6 and lever 13 are alined with the respective perforations 19 and the intermediate perforation, then the bolts 10 and 14 are inserted.

In order to lock the forks in extended relation and maintain the spring in position for working on the valve, I have provided a toothed bar 20 which is pivoted at 21 on the arm 1 of the fulcruming fork. A pin 22 projects laterally from the lever 18 and is adapted to be engaged by the teeth of the toothed bar for locking the lever 13 in a plurality of various positions.

It will be noted that the jaws 2 and 3 of the two forks not only have a variable adjustment relative to each other for embracing valve stems of various diameters lOO llO

but the end of the pivoted fork 6 and the inner end of the lever 13 Which is linked to the pivoted jaw is adjustable vertically for operating on springs of different lengths.

WVhat I claim is:

1. A valve lifter comprising a fulcruming fork provided with upstanding arms intermediate its ends, a cooperating fork having an end pivotally mounted between said arms, a lever pivoted intermediate its ends between the arms and having one end projecting forwardly and in alinement with the second mentioned fork and a link connecting the said end of the lever with the second mentioned fork and forwardly of the upstanding arms.

2. A valve lifter comprising a fulcruming fork, a cooperating fork pivoted on the fulcruming fork, a lever pivoted interme- V diate its ends on the fulcrumlng fork, a link 20 connecting the pivoted fork with one end of said lever, and means for vertically adjusting the pivotal connections of the lever and the second mentioned fork.

3. A valve lifter comprising a fulcrum- 25 said lever, means for adjusting the jaws of each fork in variable spaced relation, andmeans for vertically adjusting the pivotal connection of the lever and second mentioned fork.
