Specification of Letters Patent. Patented J n 11 1921 Application filed. February 27, 1919. Serial No. 279,643.
To all whom it may concern."
Be it known. that I, EDWIN T. KnnsHAw, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful improvements in Engines; and I. do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to motors and more particularly to internal combustion engines. The present invention is an improvement of the type of engine disclosed in Letters Patent No. 1,181,892 issued May 2, 1916, but obviously the invention. is not limited exclu:
sively to use in connection with the type of engine shown in my prior aforesaid patent.
It is one of the objects of the present invention to simplify and more accessibly arrange the details and elements of engines of the internal combustion type especially of the two stroke or double cycle character.
Another object of the. present invention is to provide a simple, practicable, reliable and durable form of connection between the tubular pist n and the connecting rod of the motor, and further object of the invention is to provide for the convenient assembling of the parts in engines of this type wherein there is arranged an internal compression or abutment member fixedly related to the engine casing and slidably fitting the tubular piston.
With these and other objects in view as will be rendered manifest to those versed in the art, the invention consists of the con-1 struction, the combination, and in details: and arrangements of parts as more par-- ticularly described in the following specification relative to the embodiment of the invention illustrated in the accompanying drawing, wherein,
Figure 1 is a vertical, central, longitudinal sectionithrough the upper portion of an internal combustion engine.
Fig. 2 is an enlarged detailed diametrical sectional view.of the upper portion of the tubular piston.
Fig. 3 is a transverse section'through Fig. 2 on line 3---3.
In the embodiment of the invention here disclosed a single cylinder 2 of a motor is shown as attached for instance, bybolts or other suitable means 3 to the crank case 4.- in which operates the usual crank and a connecting rod, not shown, one end of which is designed to be connected to the lower or inner end of a tubular piston 5*whichin the present instance is shown as having an integral inturned flange portion. 6 provided with journals 7 apertured at 8 to receive a connecting pin. Diametrically opposite side portions of the piston 5 are shown at dotted lines 9 to be slotted for the reception of a transverse bar 10 by which there is fixedly connected to the engine casing an interior cylindrical abutment or compression member or cup 11 which circumferentially snugly fits and slides in the bore of the tubular piston 5. To avoid a leakage of pressure after a fuel charge is taken in through the port 12 and a complementary port 12' in the side of the piston 5 the compression member 15 is shown as provided with packing rings 1%. Obviously compressed gases orthe fuel mixture in the cylinder or cup member 15 will pass outwardly through by-pass ports 17 to reach the upper portion of the cylinder 2 above the top 20 of the piston and to which top 20 the present invention particularly pertains.
To facilitate the organization, cleanin and adjustment of the parts of the motor have shown the head 20 as provided with a tubular portion 21, externally threaded at 22 to fit complementary threads 23 in the upper end of the piston 5 and have also shown it provided with a circumferential shoulder 24 to abut against the. end of the piston ,5 and therefore take thrust .both of compression and explosion thus relieving these pressures from the threads 22 and also form means for locking the head 20 in position now to be described. When the head 20 is screwed into position though it need not be thereby or in such manner exclusively arranged, any simple, suitable and appropriate keys may' be employed and in the present instance are illustrated as comprising diametrical rods 25 passing through respective apertures 26 in the flange or part- 21 of the head 20 and through complementar apertures 27 in the upperend of the wallof the piston 5. Preferably thepin receiving apertures 27 are placed at the bottoms of circumferential packing grooves 28 and therefore the packing rings 29 are utilized to prevent axial movement of the locking bars 25 and Tit.
to keep them out of contact With the cylinder walls in which the piston slides. Obviously various means may be utilized for securing the head 20 against rotation on the piston 5.
I claimi In a piston comprising a tubular body having external packing grooves and rings and an open ended hollow head, means for securing said open ended hollow head in said tubular body comprising a pin extending 10 diametrically through said head and body and having its ends seated beneath a packing ring in a packing groove.
In testimony whereof I afiix my signature.
EDWIN r. KERSHAW.
