VALVE TOOL. I

Application filed January This invention relates to a tool used by automobile mechanics and especially designed for use in replacing valve spring washer and pin retainers.

The primary object of the invention is to provide a device of this character whereby a valve spring retainer washer or pin may be replaced with facility eliminating any possibility ot dropping the washer or pin into the crank casing while in the act of replacing the washer or pin.

A further object of the invention is to i provide a device of this character which may be operated by the thumb and forefinger of the mechanic using the saine.

With the foregoing and other objects in -view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment ot the n invention herein disclosed. may be made within the scope of what is claimed, without departingfrom the spirit of the invention.

Referring to the drawing:

Figure 1 is a plan view of the device illustrating a washer as supported therein.

Figure 2 is a side elevational view of the device.

Figure 3 is a longitudinal sectional view.

Figure 4 is an end elevational view.

Figure 5 is a transverse sectional view.

Referring to the drawing in detail. the reference character 5 designates the bodv portion of the tool which embodies a length of sheet metal preferably of aluminum the same being provided with inwardly extended flanges 6 disposed along the longitudinal edges thereof. the flanges terminating short of the ends of the bodv portion as clearly shown by Figure 1 of the drawing. l

Oneend of the body portion 5 extends downwardly providing a curved finger piece 7 to be engaged by the forefinger of the mechanic using the device, to the end that the tool may be operated with only the use of one hand.

The opposite end of the bodv portion acts as a holder or support for the washer or pin to be inserted by the tool, and to this end, a depression 8 is formed in the outei.` end of the body portion, the depression being of a contour to accommodate the valve spring 11, 1927. Serial No.- 160,435.

pin, in a manner to prevent movement thereof while the same is being inserted in its opening in the valve stem.

Forming a part of the tool is a movable member indicated generally by the reference character 9, which is also constructed of a length of sheet metal, the same being de-- signed to move under the flanges 6, which flanges retain the member 9 in its operative position.

In order that movement of the member 9 longitudinally of the body portion will be restricted, the ianges 6 are depressed at a point adjacent to the finger piece 7 as at 10. One end of the slidable member 9 is bent upwardly and downwardly as at 11, thereby providing a thumb piece to be engaged by the thumb of the user of the tool, so that the member may be moved longitudinally of the body portion to accomplish its purpose with facility.

At the outer end of the member 9 is a spring 12 which is secured by means of the rivet 13, the free end of the spring being curved downwardly and v extended beyond the end of the member 9 so that the spring will engage the body portion when the member 9 is moved to the limit of its inward movement and in such relation with the body portion 5, that it will clamp a spring retaining washer or pin therebetween, and securely hold the same while it is being replaced on the valve stem. n'

In the use of the device, the -usual washer which in the present showing, is indicated by the reference character 15 is positioned under the spring 12 where it is securely clamped. The tool is now inserted or moved to a position wherein the substantially U- shaped opening of the washer will align withthe valve stem, whereupon the movable member 9 is moved forwardly, causing the washer to be positioned. The spring 12 which projects over the edge of member 9 acts as a gauge for inserting a pin the proper distance, within the opening of the valve stein.

. Should it be desired to replace a pin, such as used in connection with valve spring retaining washers, it is obvious that the pin. may be positioned in the depressed portion and held in such position by action of the spring 12, whereupon the tool may be moved to a position to insert ythe pin in the opening of the valve stem.

It will also be noted that due to the fact4 that the spring member 12 extends beyond the'end of the movable member, the end of the movable member will act as a pusher to push the article clamped by the spring member l2, from'the body portion.

I claim:

l. In a device of the character described, a body portion, a movable member slidable .longitudinally of the body portion, means at one end of the movable member and adapted to cooperate with the body portion for clamping an article therebetween, and means at one end of the body portion to be gripped by the thumb and foreinger of the operator for moving the movable member.

2. In a device of the character described, a body portion having anges formed along its longitudinal edges and'arranged in spaced relation with the body portion to provide a guideway, a movable member operating under the flanges, means at the outer end of the movable member and cooperating with the body portion for clamping an article at the outer end of the bodyportion, and means for permitting the operation of the movable member by the thumb of the user.

3. In a device of the character described, a body portion, a movable member supported by the body portion and adapted to move longitudinally thereof, a spring mounted on the movable member and extended beyond the end of the movable member to clamp an article between the spring and body portion, the outer end of the movable member acting as a pusher to push an article from the body portion, and said body portion and movable member having means to permit the operation Of the movable member by the thumb and forenger. y

In testimony that I claim the foregoing as my own, I have hereto attxed my signature.

HENRY M. SUSDORF.
