I 3e it known that 1,. SETH WANaMAKER, citizen of the United" States, and a resident of Ramsey, in. the county of Bergen and specification.

State of New Jersey, have made and invented certain new and useful Improvements in Devices for Facilitating the Re-' following is a moval of Valves, of which the My invention relates to devices for facilitating the removal oft-he supply or exhaust valves of internal combustion engines, and the object thereof is to provide a device for the purpose stated which is capable of a large range of. adjustment, so as to be available for use with'various makes of engine; -to provide a device for the purpose stated vhich may be readily taken apart, and packed in a restricted space; and to otherwiseimprove such devices; all as hereinafter described and claimed and illustrated in the accompanying drawing, wherein the preferred embodiment of my invention is shown.

Referring to the drawing: Figure -1 is a view showing my improved device for facilitatlng the removal of valves, and illustrating the same in use; 2 is a view showing the device itself, apart. from the engine; Fig. 3' is a viewshowing a section taken upon" a transverse plane; Fig. 4: is a view showing a bifurcated free end of an element of my device; and, Fig. 5 is a view showing a modified form of one of the elements of my device.

Referring to the drawings, the reference characters (3, 7 designate two parts which, taken together, form the frame of my device, such frame comprising a vertical portion and upper and lower laterally extending arms as shown. .The parts 6, 7 are adjustably secured together so' that the length .of the frame may be varied by varying the length of the vertical-member thereof to adapt' the device to different makes of en- The reference character 8 designates a slidable. member adjustably secured to the upper arm of the frame, which shdable member carries a threaded rod 9 at 1ts free outer end, said rod being in threaded engagement with a nut 10- upon the end of the member 8.

The reference character 11 designates a second slidable member adjustably secured to the lower laterally extending arm of the frame and the outer or free end 12 of which member is bifurcated to provide arms 13, F 1g. 4,wh 1ch arms fit upon either side of the iewerl end of the valve stem, as shown in 4 The two part frame member of my device is preferably formedfrom tubular material, and the vertical portions of said frame are in telescopic engagement with one another. as shown in Fig. '2, one of said members be ing provided with a groovel3, and the other with a set screw 14, the free end of which l1es within the groove. These features permit the vertical portion of the frame to be some makes of engines than when used with other makes.

- The upper slidable member 8 15 shown as in telescopic engagement with the upper arm 6, which is a convenient and effective construction whereby to secure adjustability of the slidable member relative to the frame, although the same end may be attained by other constructions as long as the member 8 is slidable relative to the frame. Said memher is provided with a groove '15, which groove is in engagement with the free end of the set screw 16 whichserves to hold the member in whatever position it may be placed. The lower slidable member 11 is also in telescopic engagementwith the lower arm of the frame, and is held in whatever position it may be placed by means of a set screw 17 which' engages a groove 18 formed in the member 11.

ably made in the form shown whereby the free end 12 thereof is offset. This permits above or below the axis of the lower arm of justability of 'the device as a whole is socured. A second groove 19 is provlded 1n the member 11 with which groove the set screw 17 engages when the member 11 is rotated to bring its free end 12 thereof into the position shown in dotted lines, Fig. 2.

slidable member 11, this figure showing a slidable member 20 having astraight arm necessary when the device is to be used for The lower slidable member 11 is preferthe free end 12 to occupy a position either.

so that the free end 21 thereof lies in line 7O varied in length, whereby the laterally prothe frame, whereby a greater range of ad- Fig. 5 shows a' modified form of the lower parts readily assembled and disassembled,

with the lower laterally extending arm of the frame when this form of sliding member is used.

The members 6 and- 7 which constitute the frame of my device are preferablyprovided with ribs 28 which serve'to strengthen the members and prevent them from bending .the tubular form of frame, in connection with the rib, securing a maximum of strength and rigidity with minimum weight of material.

Such being the construction of my device it will be understood,'referring to Fig. 1, that upon assembling and properly adjusting the'parts of the frame, the freeend 12 of the lower slidable member may be placed beneath the washer 22 at the lower endof the valve stem 23; andthe free end 24: of

the'threa-ded rod 9 brought into engagement the same may-be disassembled and packed in a comparatively-small space, when not in use.

Having thus described explained my device, I claim and desire to secure by Letters Patent: I
