VALVE-LIFTING DEVICE.

Application filed November 24, 1924. Serial No. 751,788.

This invention relates to improvements in valve lifting or spring lifting devices and more particularly to devices of that charactor used for relieving the spfing tension against the valves of an automobile engine in order that the spring retaining ltey' or pin may be removed from the valve stem and the valve lifted from its seat for grinding.

The principal object of this invention is to provide a device of the above character that has the advantage over other devices now generally used for that purpose in that it is adjustable to any of the common types of motors without necessitating the removal of any manifold or side equipment of the engine.

Other objects 01' the invention reside in the provision of a device of the above character that may be easily applied or removed and which cannot slip off while in use.

Still further objects reside in the various details of construction and combination of parts embodied in the invention and in their mode of operation.

In accomplisl ing these and other objects of the invention we have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein- Figure 1 is a perspective View of a valve or spring lifting device embodied by the present invention.

Figure 2 is a view illustrating the use of the device.

Referring more in detail to the drawings The spring lifting device, in its preferred form of construction, comprises two L shaped bars 1 and 2; the bar 2 being inverted in its relation to bar 1 with its vertical portion slidably fitted within the vertical portion of the bar 1.

The bar 1 comprises the horizontal arm 3 having a bifurcated end providing a notch a for the reception of a valve stem therein when the device is in use and has a vertical portion comprising two spaced apart side pieces 5 and 6 that are riveted, or otherwise secured at their lower ends to the opposite sides of the inner end of the arm 3 and at their upper end are held in spaced relation by an encircling band 7.

The bar 2 comprises a vertical member 8 that is slidably adjustable in its longitudinal direction between the spaced members of the bar 1 and has a horizontal arm 9 that is provided at its outer end with a vertically downturned portion 10 in which a pin 11, having a pointed lower end 12 extended from the lower end of the said downturned portion, is slidably contained.

Pivotally fixed by means of a pin 1a to the outer end portion of the arm 9 is a lever 15 which is connected to the upper end portion of the pin 11 by means 01 a connecting link 16; the connection being made in such a manner that pivotal movement of the lever will cause the pin to be extended or retracted.

Along the outer edge oi the vertical part of the bar at spaced intervals are notches 18, and iii-zed in the lower end of the horizontal portion 8 of the bar 2, is a pin 19 that is adapted to be seated within any of said notches to retain the parts at a desirable adjustment.

In using the device, the bars 1 and 2 are adjusted to the proper relation according to the type of engine to which the device is to be applied, with the notched end 4 ot the bar seated about the valve stem 20 and against the under side of the spring seat 21 and with the point of the pin 11 carried by the upper arm engaging with the top of the valve head 22, as shown in Figure 2. The lever 15 is then swung upwardly so as to extend the pin 11 and thus to lift the bar 2 so that the spring 23 will be sutiiciently compressed to allow the pin or key 24, upon which the spring normally rests, to be withdrawn and the valve released so that it may be removed.

A stop pin 26 is provided in the arm 9 against which the lever 16 may engage after the pin 11 has been extended and after the upper pivot point of the link 16 has been carried over the dead center line between the pivot points of its lower end and the pivot pin 14 so that the device will remain looked until manually released by pulling the lever back.

It is readily apparent that such devices may be made in various sizes, shapes and proportions and thatvarious details may be altered without departing from the spirit of the invention and for this reason it is not desired that the device be limited only to the details herein illustrated.

- Having thus described our invention, what We claim as new therein and desire to secure by Letters-Patent, is:

A deviceof the class described, comprising a vertical bar having spaced apart side members with notches along one edge, an arm extended laterally from the lower end of said bar having a notch at its outer end, a second bar vertically adjustable between the spaced members of the first bar having a pin therein adapted to seat Within the notchesofthe first bar, an arm extending laterally from the .upper end of the second bar over the first arm'provided with-a downturned end portion, a pin adjustably mounted in said downturnedend, a lever pivotally mounted on thedownt-urned end portion, a link connecting the lever and pin whereby the latter may be extended or retracted, and means for retaining the pin in extended position.

Signed at Everett, Snohomish County, lVashingt-on, this 15th day of November, 1924.
