REUBEN CHANEY, OF FORT NORTH, TEXAS.

VALVE-LIFTER.

Specification of Letters Patent.

Patented Apr. 19, 1921.

Application filed April 8, 1920. Serial No. 372,328.

To all whom it may concern Be it known that I, REUBEN CHANEY, a citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Valve-Lifters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in valve litters and has for its primary object the provision of a device that can be easily and quickly applied and will obtain a firm and even grip on the valve spring plate so that it can be lifted easily without the liability of carrying the valve upwardly with the same and which will not lose its gripping facility on account of grease or lubricant.

Another object of this invention is the provision of a support for the tool which can be easily applied to an engine and is capable of adjustment so that said tool can be conveniently positioned for engagement with a valve or the plate thereof.

A further object of this invention is the provision of a valve lifter of the above stated character, which shall be simple, durable, and efiicient, and which may be manufactured and sold at a comparatively low cost.

lVith these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my in vention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation of a valve lifter constructed in accordance with my invention and illustrating the same applied to an engine which is shown in section.

Fig. 2 is a vertical sectional view of the support.

Fig. 3 is a plan view of the tool.

Fig. 4C is a fragmentary longitudinal sectional view of the jaws of the tool.

Fig. 5 is a detail sectional view of the jaws taken at right angles to the sectional view shown in Fig. 4.

Fig.5 is a fragmentary view illustrating a modified form of handle to the device. 1

Rererrlng in detail to the drawing, the numeral 1 indicates a cylinder block of an engine having a valve chamber 2 in which the valve 3 operates. The valves 3 have plates 4 thereon for supporting the springs 5 and which plates are limited in their downward movement by keys 6. In order to remove the valve 3, it is necessary that the keys be removed from the stems thereof and in order to do this, it is necessary to raise the plates and compress the springs upwardly. The foregoing relates to a well lmown construction of engine to which my invent on is adapted to be applied. A tool 7 conslsts of a pair of pivoted jaws 8 and a pair of handles 9 which are adapted to move the jaws toward and from each other. The jaws 8 are provided with semi-circular gripping :taces 10 on which are formed spaced shoulders 11. The jaws 8 are adapted to receive the valve plates and permit said plates to rest on the shoulders while the stem of the valve is adapted to pass through or between said shoulders when the plate is raised. The jaws 8 have the usual adjustable pivotal connection 12 on which is formed an eye 13.

A support 1 1 consists of a shank 15 which has a hook 16 formed on one end thereof and adapted to engage over the exhaust pipe 17 of the engine or may be placed in engagement with the cylinder block 1. The shank 15 is slidably received within a casing 18 which is provided with a series of notches or slots 19 to be engaged by a projection 20 formed on the end or" the shank 15 whereby the casing 18 can be adjusted on the shank 15 for lengthening and shortening the sup sort 1%. A hook 21 is pivoted to the end of the casing 18 and is adapted to engage the eye 13 for pivotally connecting the tool 7 to the support. After the sup port has been applied to the exhaust pipe or to the cylinder block in the manner heretofore described, the jaws 8 of the tool 7 are open so as to receive the plate on the valve stem, permitting said plate to rest on the shoulders 11. The handles 9 are then gripped causing them to move in the direction of each other and causing the jaws 8 to tightly grip the plates on the valve stem and then by swinging the handles 9 downwardly, the jaws 8 move upwardly causing the plates to move upwardly on the valve stem compressing the spring and exposing the key on the valve stem so that the same can be readily removed and replaced as desired.

Referring to Fig. 6, the handles 9 of the tool are shown curved upwardly and outwardly so they may be easily and conveniently gripped when using the device on a V-type engine.

While I have shown and described the preferred embodiment of my invention, it Will be understood that minor changes in construction, combination and arrangement of parts may be made Without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, What I claim is A valve lifter comprising a tool adapted to grip the plate of a valve, a casing de- 20 tachably and pivotally connected to the tool and having spaced s1ots, a shank slidable in said casing, a projection on said shank and adapted to receive either of the slots to adjust the shank in relation to said cas- 25 V.
