ENGINE-HEAD- BEMOVING DEVICE.
Specification of Letters Patent.
Patented Nov. 9, 1920.
Application filed 'April 10, 1919. Serial No. 288,952.
T 0 all whom it may concern:
Be it known that we, SETH T. HALL and CLARENCE H. CROWLEY, citizens of the United States, and residents of Boone, in the county'f 360m and State of Iowa, have invented a certain new and useful Engine- Head-Removing- Device, of which the following is a Specification. I r
The object of our invention is to provide an engine head removing device of simple, durable and inexpensive construction.
In removingthe head of an automobile engine or the like it is quite a common in-' stance that when the bolts are removedthe head sticks to the engine block and is hard to remove.
Our device, therefore is designed for pulling the engine head away from the engine block.
A further object is to provide such a device having a screw-threadedrod with a sleeve mounted thereon, having at its cen-' tral portion an angular head for receiving a wrench and having at its ends a screw threaded portion. These portions are screw- 'threaded according to the screw-threads used on two of the standard spark plugs.
The rod is designed to be extended through the spark plug hole and the sleeve is screwed into the spark plug hole. By screwing the rod farther in, it'may be made to engage part of the engine block and'force the head upwardly away from the block.
At the outer end of the rod is a cross member forming a lever for operating the rod, and having at its ends portions designed to form feet, so that when two of these devices are installed in an engine head and the engine head is removed, the engine head may be inverted and supported on the removing device. i
With these and other objects in view our invention 'consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claim and illustrated in the accompanying drawings, in which:
Figure 1 shows a vertical,sectional view through a portion of an engine and enginev head, with one of our engine head remo. our: devices installed therein.
verted position, conveniently accessible for work on the head.
In the accompanying drawings we have used the reference numeral 10 to indicate generally that portion of an engine block shown.-
Above the block 10 is the head llvhaving the spark plug holes 12.
Our improved device comprises a screwthreade'd rod 13 on which is mounted a sleeve 14 the central portion of'which is angular as at 15 to receive a wrench.
' ()ne end of the sleeve 14 is provided with screw-threads 16 of the same. number and pitch as certain standard spark plug screwthreads, and the other end is provided with screw-threads 17 of another number and pitch corresponding with the screw-threads on another type of spark plug. These two sets of screw-thread members 16 and 17 may be 'used with practically all of the engines commonly used.
' Extended through the outer end of the rod 14 is across rod 18 having at its ends outwardly turned members or feet 19.
In removing the head from the engine,
the ordinary fastening bolts are taken out.
The sleeve 14 is screwed toward the free end of the rod 13 and saidfree end is inserted into the spark plug hole 12.
The sleeve 14 is then screwed into the spark plug hole, and the'rod 13 may then be screwed inwardly by means of the rod 18 until the inner end of the rod engages the engine block, whereupon it will be seen that the head may be forced upwardly. We preferably use two of the rods 13 extending them through the two end spark plug holes.
When the engine head has been loosened from the block, it may be lifted out bodily, inverted, and then set on a'bench or the like, and the rod 18 with the feet 19 will properly support the engine head, so that the carbon may be cleaned from the inside thereof, or any other work desired may be done on the head.
engine head and rest it on a bench or the like it is necessary to place blocks or other filler means between parts of the engine head and the bench. in order to make the engine head rest solidly on the bench.
Some changes may be made in the construction and arrangement of the parts of our device without departing from the essential features and purposes of our invention, and it is our intention to cover by our claim any modified forms of structure or Letaem use of mechanical equivalents which may be reasonably included within their scope:
Vi e claim as our invention:
- A device for removing engine heads comprising an externally and internally screwthreaded sleeve having an externally angular wrench receiving portion, a screwthreaded rod received in said sleeve, having on one end a head and having at the other end a cross rod formed at its ends with projecting portions forming feet projecting away from said head substantially as described, whereby when two of said devices are screwed into an engine head, said cross rods may be turned to such position that the engine head may be inverted and supported upon said devices.
