JOSEPH SUNNEN, OF ST. LOUIS, MISSOURI.

VALVE LIFTER.

Application filed August 9, 1921. Serial No. 490,968.

To all whom it may concern:

Beit known that I, JosnPH SUNNEN, a citizen of the United States, residing at city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Valve Lifters, of which the following is a full, clear, and exact description,- such as will enable others skilled in the art to which it apperta-ins to make and use the same, reference being had to the accompanyingdrawings, forming part of this application' My invention relates to valve lifters and is an improvement upon the valve liftersdisclosed in United States Letters Patent No. 1,369,142 dated February 22, 1921.

The objects of the present invention are to provide a valve lifter of the class disclosed in the above patent and provided with oppositely disposed adjusting members seated in and projecting outwardly from the opposite ends of each jaw and adjustable so that said jaws can be contracted and expanded laterally.

Further. objects of my invention are to provide a tubular member nonrotatably seated in one end of the jaw and havingthreaded engagement -with the threaded end of opposite end of said jaw, said tubular memher and said adjusting screw projecting inwardly from said jaw whereby the outer sides of the 'jaws'are devoid ofany projections large enough to interfere when the device is being used.

Still further objects of my invention are to generally improve and simplify the construction, and cheapen the cost of manufacture and assembling of valve lifters of the class described. I

With the foregoingand other objects in view, my invention consists in certain novel features of construction and arrangementof parts hereinafter more fully described and claimed in the accompanying drawings, in

which Figure 1 is a side elevation of a valve lifter of my improved construction.

Figure 2 is a top view of the same.

Figure 3 is a vertical cross section taken on the line 33 of Figure-1.

Figure 4 is a detail perspective view of the tubular threaded member and a portion of the jaw showing-the seat therefor.

Referring by numerals to the accompanying drawings, designates the upper jaw member comprising substantially parallel ends 11 connected at their rear portions by a base plate 12. -Projecting forwardly from this plate and disposed below said ends 11 are a pair of lugs or ears 14 to which is pivotally mounted by means of pin or rivet 15 the lower jaw member 16 which comprises substantially parallel ends 17 having a rear or base portion 18. This base portion has an upwardly extending projection 19 which occupies a position between the ends 11 and immediately in front of the base plate 12. A screw 20 has threaded engagement with the base plate 12 and the threaded end thereof projects forwardly and inwardly within jaw member 10 and bears against the upward projection 19 of the lower jaw member 16.

In order to provide sufficient bearing for screw 20, an internally threaded tubular member 21 can be fixed tothe base plate 12 to form a threaded seatffor screw 20. The outer or free end of screw 20 is provided with suitable projections 22 whereby said screw can be conveniently manipulated. The lower edges'of ends 11 are turned inwardly to form horizontally disposed flanges 11 which are adapted to engage a spring washer carried by the lower-stem of a valve stand. The lower edges of ends 17 of jaw member 16 are provided with horizontally disposed inwardly projecting flanges 17? which are designed to rest on the portion of the cylinder casting immediately below the valve stem or on parts associated with'the valve push rod, 2 W V Inasmuch as the valves of the various makes of automobiles vary in size and the space available for positioning the lower jaw adjacent to the push rod varies, in some cases being very limited, provision is made-for of shank portions 26 formed integral with.

tubular members and seatedin seats 27 formed in the corresponding ends of said jaws In order to retain tubular members 25 in their respective positions, the ends 26 of shank portion 26 are bent transversely so as to bear against the. outer walls of the jaw ends in which shank portions 26 are seated.

' In the operation of my device, the valve litter is placed in positiomas shown in Figure 1, with the ends 17 of the lower aw resting on thecylinder casting or other stationary support and the ends 11 of the upper jawlO engaging the underside of the spring washer fixed to the valve stem of the valve which it is desired to lift. By turning screw in the proper direction, jaw member 10 is caused to rock on the pivot 15 so that the ends 11 are moved upwardly to compress the valve spring and raise the valve stem and the valve carried thereby.

In order to adjust laterally the ends 11 of jaw member 10 and the'ends 17 of jaw mem ber 16, screws 24: are turned in proper direction causing the ends of the respective jaw members to move towaros each other, and vice versa, by virtue of the fact that the threaded end' of each screw 24 is in threaded engagement with the tubular memher non-rotatably carried by the opposite end of the respective jaw.

A- valve litter constructed according tomy invention isinexpensive to manufacture, can be easily and quickly assembled, and having no outward pro ections on its valve engaging ends, can be used in engines having very restricted space in which to operate.

It will be readily understood that minor changes in the s ze, i'orm and construction of the various parts of my improved valve lifter may be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scope-of which is set forth in the follow ing claims.

I claim:

l. -A valve lifter comprising a pair of jaws pivotally'connected at their base portions, means carried by'one of said jaws and operiy engaging the other jaw for moving jaws about their pivotal connection, and means seated in the opposite ends of each jaw and projecting inwardly therefrom toward each other to form operative engagement for adjusting the ends of each jaw laterally.

A valve lifter comprising a pair of U-shap'ed jaw members pivotally connected at their base portions, means screw-seated in the'base portion of one of said jaws and engaging the base portion of the other jaw whereby said jaws can be adjusted relative to each other, a member rotatable in one end of each jaw and projecting inwardly towards the opposite end, an inwardly projecting member non-rotatably seated in said oppositcend of each jaw and in threaded engagement with said rotatable member whereby the respective ends of each jaw can be adjusted laterally relative to each other by manipulating said rotatable member. V 3. A valve litter comprising a pair of U-shaped jaw members pivotally' connected adjacent to their base sections, an adjusting memberscrew-seated in the base section of the outer jaw member and having its inner end engaging the base portion of the inner jaw member whereby said jaw members can be adjusted relative to each other, a threaded member rotatably carried by one end of each jaw, member, and a tubular member nonrotatably carried by the opposite end of each-jaw, member and in threaded engagement with its corresponding threaded member, whereby by the turning of said threaded member, the ends'of each jaw can be adjusted laterally.

at. A valve lifter comprising a pair of U-shaped members pivotally connected adjacent to their base portions, means "for adjustingsaid'U-shaped members, relative to their pivotal connection, a rotatably threaded member extending inwardly from one end, of each jaw member, and an internally threaded sleeve adapted; to receive the threaded end of said rotatable member and provided with a shank portion non-circular in cross section which engages a non-circular seat formed in the opposite end of: each jaw member. I I j a I In testimony whereof I hereunto afiix my signature this sixteenth day of July, 1921.

JOSEPH SUN NEN.
