Application filed. November 5 1921. semi No. 513,125.

T 0 (LE whom, it may concern:

Be itknown that I, ELMER P. KRAY, a citizen of the United States, residing at LosAng'eles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in" Valve Replacers', of which the following is a specification.

My invention relates to a tool for replac= ing compressed valve springs, upon internal combustion engines. I

An important object of the invention 'is to provide a tool of the above-mentioned character, which is adapted to save time and labor, in the handling of compressed valve springs, in replacing the same in position upon internal combustion engines.

A further object of the invention is to provide a device of the above-mentioned character, which is adjustable for receiving and holding compressed, springs of different lengths and diameters.

A further object of the invention is to provide a device of the above-mentioned character, which is simple in construction, strong and durable.

Other objects and advantages of the in vention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a perspective view of a device embodying my invention,

Fig. 2 is a side elevation of the same,

Fig. 3 is a plan view of a vice, showing a spring compressed therein, and held within my tool, parts of the tool being in section, and.

Fig. 4 is a side elevation of a lug or bar.

In the drawings, wherein for the purpose of illustration, is shown a preferred embodimentof my invention, the numeral 5 designates a pair of spaced arm sections provided at their rear ends and upon their outer surfaces with transverse teeth or serrations 6, to engage with co-acting teeth 7 formed upon arm sect-ions 8. The arm sections 5 and 8 have longitudinal slots 9 and 10, re- 4 ceiving bolts 11, carryingwinged nuts 12. The arms embodying the arm sections 5 and 8 are therefore longitudinally adjustable. The rear ends of the arm sections 8 are preferably curved, at'13, and these curved portions are hinged together, as shown at l4.

The armsS are provided at their forward ends with pairs of adjustable transverse"v jaws. Each pair embodies a laterally and inwardly extending jaw 15' carried by a transverse shank 16, formed integralwitli upon its inner side with teeth 17, to engage the arm section 5.' The shank'16 is provided teeth 18 formed upon a'tr'a-nsvers'e shank19,

carrying a jaw 20 and its upper end extend ing laterally and inwardly. The shankslG and 19 are provided with longitudinal slots 21, receiving a bolt 22, carrying winged nuts 23. It is thus seen that the jaws of each pair may be adjusted toward or away from each other, depending'upon the diameter of the spring, by means of a turn-buckle 24, carrying a milled head or nut 25, as shown. The rod 24 has its end portions screw-threaded, which'screw-threads are oppositely pitched and these screw-threaded ends engage within screw-threaded openings 26, formed in the arm sections 5, as shown.

In Fig. 3, are shown the tops of'vice jaws 27, which may be moved toward or away from each other by the usual means. Nu-

meral 2S designates inverted L-shaped lugs or bars, Fig. 4, to fit over the jaws 27 and compress therebetween a spring 29;

v The spring iscompressed independently of my replacing tooland after being thus compressed, the jaws of the tool being properly adjusted, such jaws are placed over the ends of the compressed spring, Figs. 2 and 3. The jaws 27 of the device may now be opened and the spring will be held within the jaws of the tool. The tool may now be employed in replacing the compressed spring in position upon the engine. The valve stem is now dropped through the spring and locked.

The tool is pulled off of the spring and the operation is completed.

It is to be understood that the form ofmy invention herewith shown and described is to be taken as a preferred example of the.

same, and that various changes in the shape,

size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the "subjoined claims.

Having thus described my invention, I claim:

1. A valve spring replacing tool comprising, a pair of spaced arms pivotally connected at corresponding ends'whereby said arms may be adjusted toward and away from each other, means adjustably connect;

carried by the ends of said arms, the jaws in each pair being spaced.

2. A valve spring replacing tool comprising, a pair of spaced arms whichare adjustably connected so that they are adapted to be shifted toward and away from each other, a common adjusting element connected with both of said arms and adapted to shift them toward and away from each other and hold the same in the adjusted position, a pair of inwardly extending jaws,

carried by the arms, the jaws ineach pa r being spaced and adapted to receive and I hold a compressed spring.

3. A valve replacing tool comprising, a pair of spaced arms, a common element adjustably connecting the arms and adapted to shift them toward and away from each other and to hold them in the adjusted position, a pair of inwardly extending jaws carried by the ends of said arms, said jaws having their inner contacting faces substantially straight, and means whereby the jaws in each pair may be adjusted toward and away from each other.

4. A valve spring replacing tool comprising, a pair of spaced arms, a hinge connecting corresponding ends of said arms, means whereby each arm is longitudinally adjustable, a turn-buckle rod having screwthreaded engagement with said arms vto move them laterally upon the hinge, pairs of jaws carried by the ends of said arms and extending inwardly, and means whereby the jaws in each pair may be adjusted toward and away from each other.

5. A valve spring replacing tool comprising, a pair of spaced arms, and a pair of shanks carried by the spaced arms and arranged at substantially a right angle thereto, said shanks being provided with inwardly projecting pairs of jaws, the jaws in each pair being spaced.

In testimony whereof I aflix my signa ture. I

ELMER P. KRAY.
