Application led february 28, 1924. Serial No. 695,'A62.
useful Improvements in an Engine Cylinder and Piston, of which the following is a specification.
This invention relates to new and useful improvements in internal combustion engines and more particularly to the cylinder and piston construction thereof.
One of the principal objects of the present invention is to provide a cylinder and piston construction, which will be very efficient in operation, and of such construction, as .to prevent the carbonization of the inner wall of the cylinder.
Another object of the present invention is to provide a cylinder and piston construction of the above mentioned character, wherein the same are substantially angular in cross section, pairs of oppositely arranged piston rings being provided and adapted to engage the respective walls 'of the cylinder.
Another important object of the present invention is toprovide a device of the above mentioned character, which is simple in construction, inexpensive, strong and durable, and further well adapted for the purposes for which it is designed.
.Other objects and advantages of this invention will become apparent during the course of the following description.
- In the accompanying drawing, forming a part of this specification, and in which `like numerals designate corresponding parts throughout the same:
Figure 1 is a vertical section through a cyllnder showing the piston mounted therein, in side elevation. t
Figure 2 is a transverse section, taken on the llne 2 2 of Figure 1.
Figure 3 is a transverse section through the piston, showing the piston rings in plan elevation. f
Figure 4 is a side elevation of one of the units of the piston ring.
In the drawing, wherein for the purpose l of illustration is shown the preferred embodiment of my invention:
The numeral 1 designates the outer wall of the cylinder, designated generally by the numeral A, spaced therefrom in a manner shown at 3,
and the inner wall 2 isto provide a water jacket. The pur ose of this construction is well known in t e art, and it is not thought necessary to further go in detail relative to the same.
The outer walls 'of the cylinder A areV preferably rectangular. The outer faces of the inner wall 2 of the cylinder are also rectangular in design The inner walls of the faces 2.are substantially rectangular in cross section, and at each of the corners thereof,
a bevelled face is provided, such asis illustrated at 4 in the drawing. It will thusbe seen that a cylinder has been constructed' which is substantially angular in cross section for the purposes hereinafter set forth and described.
Operating within the cylinder A in the usual manner is the piston 5. The latter is substantially of the same shapeas the inner walls of the cylinder, and also angular in cross section, for cooperation with the faces of inner" wall 2 of the c linder A. The corner of the outer faces ofy the piston 5 are also bevelled as shown at 6 in the drawing, to conform to the shape o f the bevelled portion 4 of the cylinder.
Formed in the'outer faces of the walls of the piston 5, and extending circumferentially therearound, are the grooves or channelsV 7. The purpose of providing the grooves 7 is to receive the piston rings which are supported therein, and the piston rings in the present invention comprise the plurality of units each of which are of the same construction and the same is clearly shown in Figures 4 and 5 of the drawing. Each unit' 8 is in the form of a substantially long strip of metal and has its ends slotted with the cut-away portions 9A for a purpose to be presently described. 'I1-he end portions 10 of each of the strips 8 are also provided with the bevelled edges f11 in the manner as shown in Figures 3 and 5 of the drawings.
In position, the strips or units 8 are placed in the channels formed in the piston 5, in such a mannen as to have the strips arranged in pairs. In this manner, it will be readily seen that, the en ds of one of the pair of strips will overlap vthe ends of the Adapted to e disposed between the rear Whereby the piston will t snugly in the cyl`I faces of'each of t'he strips 8 and the res ective sides of the piston 5 are the resilient springs 12. The purpose ofthese springs 12 is to provide ra means for normally urging the opposed pairs of strips 8 which form the piston rings into engagement with the inner faces of the inner Wall 2 of the cylinder, in such a manner as to have the outer faces of the strips engaging the straight faces of the cylinder and the bevelled portions of the overlapping strips operating with the bevelled faces 4 of the cylinder,
inder in engagement With all of the inner faces of the inner wall thereof and will prevent the loss of compression or the leakage of oil past the piston into the cylinder.
The* simplicity of my device enablesthe same to be readily disassembled Wheneverlnecessary, and is of such a construction as to insure lche efiicient operation of the. same, and will n`ot only be strong, but
also durable, thus prolonging the length of use of the cylinder and the piston.
While I have shown the preferred embodiment of my invention, it is to be understood that various changes inl the shape,
"of the invention an size, and arrangement of parts -maly be' re-y sorted to, without de arting from spirit the scope of the appended claim.
Having thus described my invention, what I claim is: y
In combination with a c linder having plane rectangularly disposer? side wall suraces with intervening planes, and rectansections overlapping eachother, said rin i' section being received in the ring groove an springs interposed between the ring sectlon and the inner wall sectionof the groove.
In testimony ywhereof I ax my signature.
