Specification of Letters Patent.

Patented Oct. 26, 1909.

Application filed September 16, 1905. Serial No. 278,735.

To all whom it may concern;

Be it known that I, JOHN V. RICE, Jr., a citizenv of the United States, residing at Bordentown, in the county of Burlington and State of New 'Jersey, have invented certain new and useful Improvements in Internal- Combustion Engines, of which the following is a specification. I

One object of the present invention is to improve the construction and mode of ,o'peration of the provisions which eflect the compression necessary for operating an internal combustion gas engine.

Another object of the invention is to effect the necessary compression without having recourse to the crank case or to the cylinders in which the explosion occurs thereby obviating the well understood disadvantages which such ractice entails.

Another- 0 jeet of the invention is" ta provide for running an engine of the type recited on a comparatively low ade gas and f compression means other than such as are self-contained in the engine.

Another object of the invention is to provide a self-starting multiple cylinder engine operate properly without a fly: wheel or at any rate with a relatively small one.

Another object of the invention is to proengine in which the for effecting compres-' unobjectionable, simple employed for that purcrank case is not use and novel means are pose; and-other objects of the invention will appear from the following description.

To these and other ends herelnafter set forth the invention comprises the im rove- 'inders shown in Fig; 1, illustrating ments to be presently-described; and. ally The nature, characteristic features and scope of my invention will'be"more fully understood from the following description taken in connection with the accompanying drawings forming ;-part hereof-; and gin Figure 1, isa view inf" vertical section-- illustrating portions ofv aj multipleggglind'en internal combustion en in'e em ying features of the invention. ig, 2, isa' rear'elevatienal view of the cyl; the ports thereof; Fig. 3, is a side elevatlonal'view ofthe engine shown Fig. 1, and Fig. 4,-is.

' structionmaterially shortens and lowers the 11, by ineans of which I parted to 'the shaft12,

means-Bot exit for the pro tion', all'of which are too well understood to a View single embodying features of the invention and ar- I ranged for operation in drill or the like.

In the-drawings I have shown cylinders each having at its extreme ends explosion chambers l and 2, arranged in alinement and having intermediate of its ends an enlarged compression chamber 3. Good practice and machine design dictate that the chambers 1, 2 and 3, should be internally cylindrical and I that the cylindrical chamber 3, should be arranged eccentrica-lly in respect to the chambers l and 2, and such a construction is therefore chosen for the purposes of. illustration, but the invention is of course not intended to be limited to this particular embodiment. Arranged for cooperation with the described cylinder is a piston having its ends 4 and 5, properly fitted to tlie explosion chambers 1 and 2, and having an enlarged offset intermediate-portion 6, properly fitted to the compression chamber 3, which conconnection with a center of gravity of the engine. The ends shown as rovided with packing as externa ly cylindrical so as to suit them for cooperation with the parts 1,2 and 3. Furthermore the portion 6, is shown as dis.- posed eccentrically with respectto the parts 4 and-5.

Referring to Figs. 1 and 2, 7, is a pistonv rod applied to the intermediate portion of thepiston and working through the compression chamber 3,1so that its stufiing box orgland 8, is not exposed toan undue degree of heat and is thereforedurable and easily kept tight. The piston rod 7, reciprocates 'a cross-head 9, and the cross-head is connected with a" link rotary motion is imthrough the intervenrings and tion of a. drank 13.

jackets, and there are appropriate provisions-for 1gn1t1ng t e char nets of combusrequire 17, are I castings special description. 14, 15, 1'6 and ports illustrated as formed within 4 and 5, and the intermediate portion fi, are

in suitable ways 10, I

As illustrated, the cyl- 19 inders comprise sections of castings suitably secured together and they may be provided with spaces as shown which constitute water es and affording 106 18, secured tothe cylinders of the pression chamber 3, of one cylinder with the I ex' losion chambers l and 2, of the adjacent cy inder. The charge is of course introduced into the. compression chambers as at 19, and 20, represents exhaust provisions.

In Fig. 4, the piston rod is arranged in the compression. chamber and is shown as made in two parts 21 and 22, of which the part 21, is secured to the piston and the part 22', isarranged ,to carrya drill-or the like. 23-and 24, are the ports "which may be variously and appropriately arranged.

V It will be obvious to those skilled in the art to which my invention appertains that modifications may be made in detail without departing from the spirit thereof, hence the invention is not limited further than the state of the art may require, but

Having thus described the nature and Ob-v jects of my invention, what I claim as new and desireto secure by Letters Patent is:

1. In. an internal combustion engine, the combination with a cylinder having an eccentric compression chamber between its ends, and a piston in said cylinder-having an intermediate eccentric portion fitted to said compression chamber.

' 2; The combination in an internal combustionengine, of a pair of cylinders arranged side by side, having closed ends forming explosion chambers, and eachrhavs ving, intermediate between its ends, an enlarged compresslon chamber, pistons working in the said cylinders and having-their ends fitted to the said explosion chambers, and each havingalso an intermediate portion fitted to a compression chamber, and fluid conduits between the said compression chambers and the explosion chambers, a conduit leading from one end of each compression chamber to an explosion chamber of the other cylinder.

, 3. The combination in an' internal combustionengine, of a cylinder having closed ends forming explosion chambers, and having also intermediate between its ends an eccentric compression chamber, and a iston in the said cylinder havingits ends tted to .the said explosion chambers and having also an intermediate eccentric portion fitted to the said compression chamber.
