WILLIAM, LEE ROY TRIMBLE, OF GRANBUBY, TEXAS CYLINDER HEAD STAND Application filed. March 30, 1929. Serial No. 351,332.

- convenient in its arrangement of parts, easy to manipulate, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects inview as will appear as the description proceeds, the invention resides in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a top plan view of the stand embodying the features of my invention.

Figure 2 is a side elevation thereof.

Figure 3 is another side elevation thereof showing the stand in a'differentposition.

Figure 4 is a detail transverse section taken substantially on the line 44'of Figure 3. v

Figure 5 is a perspective view ofthe spring compressor. t 'Figure 6 is a detail section taken substantially on the line 6-6 of Figure l; v

Figure;.7 is a bottom plan View. of the cylinder head holding frame with the head therein. I

Figure 8Iis a detail section taken-substantially on the line 8-8 of Figure 7.

, Figure 9 is a detail section taken substantially on the line 9-9 ofFigure 1.

Referring to the drawings in' detail, itwill be seen that the numeral 5 denotes the top of thework bench on which is mounted a substantially rectangular base frame B, including ends6 and 7, and sides 8, which are offset intermediate their ends as at 9, so that the width of the forward portion of the base frame is slightly greater than the rear portion thereof. Ears '10 project from the cross member 7, while ears 11 project from the rear cross member 6 and these ears 10 and 11 are screwed or otherwise secured to the bencl1 5. A pair of spaced parallel transverse ledge bars 14 have depending end extensions 15 ofiset as at 16 and secured between the front end portions of the side bars 8, so that a cylinder head 17 may rest thereon. A pair of arms 18 are pivotally mounted between the rear ends of the sides 8 by means of a cross rod 19. A rectangular cylinder head holding frame 20 has its ends pivoted as at 21, to the ends of the arms 18. A pair of end plates 22 extend across the frame and are longitudinally slotted as at 23. The head '17 rests on these plates 22 and a strap 24 is hingedly mounted as at 25, on one side of the frame 20 and has an angularly extending end 26 provided with indentures 27. The ends 26 areadapted to be passed through loops 28 on the other side of the frame 20 so that set screws 29 may engage in the indentures 27 and hold the head in place.. Thus, this holding strap is adjustable to fit different sized heads. A rod 30 has ends 31 extending through the slots 23 so that therod 30 may be slid along the plate 22 either to an out of the way position as shown in full lines in Figure 7 or to a position toward the center as is shown in dotted lines in Figure 7, to prevent the valves 33 from falling out of the blocks after the springs and keys have been removed. Links 33 are pivoted together as at 34, and as at 35 are pivoted tointermediate portions of the arms 18'and as at 36 to the sides 8 immediately forwardly of the offset portions 9. Spring means 37 tend to hold the links in alignment with the arms 18 raised, that is, at an acute angle to the base frame 13.

By breakin the links, it will be seen that the holder frames and the arms will swing donwwardly so that the block may rest on the ledge bars 14. This spring means 37 1s anchored on the rod 19 by means of a link 38, and is anchored to the lower links 33 by a tie rod 39 of V-shaped formation. The pivot means 3 5 is in the form of a rod extending between the arms 18 and arms 40 are pivotally mounted thereon and held together by cross braces 41. A rod 42 extends between the extremities of the arms 40. A sleeve 43 is slidable on the rod 42 and has an arm 44 extending therefrom, to which is pivotally engaged a spring compressor 45, having a bifurcated end 46 for engaging a valve spring. By placing the valve head in its cylinder head holder and clamping the same in place as described heretofore and placing the rod 30 in the dotted line position in Figure 7, it will be seen that the links 33 may be broken to allow the arms 18 to swing downwardly and rest the cylinder head block on the ledge bars 14 and then the arms 40 may be swung upwardly and the arm 44 swung over to extend forwardly and may he slid transversely so as to engage the spring compressor 47 with the springs of the valves so as to release the keys one at a time. After this has been accomplished the arm 44 and the arms 40 may be swung out of the way and the holder 30 moved upwardly and reversed and then moved downwardly to again rest the cylinder head on the ledges 14, for valve grinding purposes.

It is thought that the construction, operation, utility and advantages of this invention will now be quite apparent to those skilled in this art, without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail, merely for the purposes of eXem-plification, since in actual practice it attains the features of ad vantage enumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the details of construction, and in the combina tion and arrangement of parts may be resorted to, without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what is claimed as new is:

1. A stand of the class described for a cylinder head including a base structure, a swinging structure mounted in the'base structure, a holder rotatably mounted in the swinging structure, a ledge on which the head may be rested, a pair of links pivotcdtogether and pivoted to the swinging structure and base structure for holding the swinging structure raised, said holder comprising a rectangular frame with plates across the ends thereof so that a cylinder head may be mounted therein, and adjustable strap means on the frame for holding said head in place,
