*ENGINE Application -1ed May 6, 1925. Serial `N'o. '2S-,431;

T0 l, all 'whom it may concern Be it knownthat I, CARL B. KING, a citizen -of the United States, residing at Shoemaker, in the county of Mora and State of New Mexico, have invented new and useful Improvements in Engines, of which the following is a specification.

This linvention relates vto internal coinbustion-engines, particularly to the cylinder construction thereof, and has for its-objectthe provision of a novel engine or engine cylinder embodying a spring pressed sleeve arranged in surrounding relation to the. usual piston and vacting automatically to give the ,proper space for combustion regardless o f whetherfon a full or partial charge of gas or explosive mixture.

-An import-ant object is the pro-vision of an engine of this character so Constructed and arranged as to insure a more complete exhaust, a better mixture for iiring, a quicker expansion of the gas, better cooling conditions, the -relieving ofthe strain on t-he bearings especially at the time of firing, 1 the above mentioned advantages lor conditions naturally resulting in the production of greater power with less fuel `consumption.

A more specific object is the provision of an engine in which the cylinder is equipped with the sleeve which is spring pressed toward the crank shaft, the sleeve being more ovei heated and containing the ignition device, commonly a lspark plug.

\Anadditonal`object is the provision kof an engine of this character which will be comparative simple and inexpensive in manufacture, highly efficient and durable in use and a general improvement inthe art.

With the above and other objects and advantages in view, the invention consists in the details of construction to 'be liereinafter more fully described and claimed and illustrated in the accompanying drawings in which:

Figure 1 is a transverse vertical section taken through an engine constructed in accordance to my invention, the parts being shown in one position, and

Figures 2, 3 aiid 4 are similar views with the various parts shown in different positions or at different points `in the stroke of the piston.

Referring more particularly to the drawings, the numeral 10 designates the usual crank `case upon which is mounted the cylinder casting or block 11, while 12 represage-of fuel'imiXture from theinlet `16 to` thef'chamber 217 is controlled by a. valve 19 here disclosed as being Aof. the V'tappet or poppet type, which valve Vhas the usual stem (lil 20 .slidable vthrougha guide 21 land held, Y by aspring 22, in engagement with a push rod 23 actuated by means of the usual cam i device 24. The exact mechanism for `operatingthe cam devices is not shown as it formsno part of the present invention.` It

should also `be stated that it is preferable to provide the usual water jacket 25 for the purpose ofeifecting cooling of the en-V gine cylinder. Vhile cylinder is referred to it should be understood that of course there may be any desired number of ycylinders, all of which would be constructed in the same manner. v Y l The lessential feature ofthe invention lies intheprovision of asleeve y26 which .is of the elongated cylindrical form and which iits-slidably within the cylinder A11'. This sleeve has its bottom or end toward Vthc crank casevopen andits other end provided with a head-27 at the center of which is vanupstanding Vtubular projection'28 slidable throughthe opening in the top wall 14 of the casting or cylinder block. The spark plug 429- of Aany ordinary or preferred type is located within the tubular extension 26 and isthreadedtlirough a suitable 'hole 30' in the head 27. On the upper surface `or top ofthe head2? is a'peiipheral upstanding flange 31 which forms retaining means' Vlocated at the lower end of the cylinder and secured in anydesired manner as for example by means of a screw 34 or any desired number of screws. The usual piston 35 is of course slidably mounted within the sleeve 26 and has connected therewith the miv usual connecting rod 36 which is in turn connected with the crank portion of the crank shaft. In one side the sleeve 2 6 is formed with a port 37 designed to be brought into registration with the inlet port 18. Quite naturally, the exhaust `valve structure is identically the same though thisv early part of power stroke` and the-'spring further acts to bring thepower of the explosion farther down yon the stroke instead of wasting power,;under extreme pressure, past the rings and valves. n In order to kee-p the top of the cylinder sleeve 26 cool and to facilitate vaporization ofthe incoming charge sovv that custo-mary combustibility will be increasechit is preferable that the chamber 38 containing the spring 32 be connected by a pipe 39 or the like with the ,air kintake of the carburetor so that the air drawn through the pipe 39 and furnished to the carburetor will be warm. Obviously, no fuell mixture can enter the sleeve through the port 18 until the sleeve is in such position that the yports 37 and 18 register and in this way it is apparent that the device will act automatically to maintain the proper balance at all times and insure proper and `eflicient operation ofthe engine. If desired it may provide an auxil-` iary exhaust port- 40 in the cylinder for the purpose of decreasing pressure in case of an excessive charge of gas.

VJhile I have shown and described the preferred embodiment of the invention, it should be understood that I reserve the right to make such changesin the form, construc` tion and arrangement of parts as will not depart` from the spirit of the invention or the scopevof the sub'joined claims.

Having thus described the invention, I claim: v

1. In an engine including a crank case, a crank shaft journaled therein and having crank portions, the engine further having a valve controlled fuel inlet port communicating with the cylinder, a sleeve slidably mounted within the cylinder and having its bottom open and its top closed by a head,

a spark plug carried by the head, a spring located above the head normally urging the sleeve downwardly, a piston slidably mount-- ed within the sleeveiand having a connecting rod connected with the crank portion of the crank shaft, said sleeve being formed in its wall with a port adapted to register with said inlet port, the sleeve being in frictional engagementwith the piston and moved thereby in one direction.

2. In an engine including a crank case, a crank shaft joui-nailed therein and having crank portions, the engine further having a. valve controlled fuel inlet port communicating with the cylinder, a sleeve slidably mounted within the cylinder and having its bottom open and its top closed by a head, a

spark plug carried by the head, a spring located above the head normally urging the sleeve downwardly, a piston slidably mounted within the sleeve and having a connecting rod Aconnected with the crank portion of the crank shaft, said sleeve being formed in its wall with a port adaptedto register with said inlet port, the cylinder -having a top wall with a central opening, and said head having a tubular extension slidable through said opening and formingan enclosure for the spark plug. v In an. engine including a crank case, a crank shaft journaled therein and having crank portions, the engine further having a valve controlled fuel inlet port communicating with the cylinder, a sleeve s-lidably mounted within the-cylinder and having its bottom open and its top closed by a head, a sparkplug carried by the head, a spring located above the headnormally urgingthe sleeve downwardly, a piston slidably mounted within the sleeve anda connecting rodvco'nnected with the crank portion of the crank shaft, said sleeve being formed in its wall'kwith a `port adapted to register with said inletv port, the cylinder having a top wall with a central opening, said head hav-` ing a tubular extension slidable through said opening and forming: an enclosure for the spark plug, the top wall serving asone abutment for the spring and the head serving as the other abutment therefor. In testimony whereof I affix my signature;

CARL B. KING.
