UNITED STATES PATENT OFFICE.

GURDON PENDLETON, OF GROTON, CONNECTICUT, ASSIGNOR TO THE THAMES MOTOR COMPANY, OF NEW LONDON, CONNECTICUT, A CORPORATION OF CON N ECTICUT.

EXPlLOSlVE-ENGINE.

Specification of Letters Patent.

Patented Feb. 27', 1906.

Application filed August 31, 1904. Serial No. 222,826.

To all whbm it may concern:

Be it known that I, GURDoN PENDLETON, a citizen of the United States, residing at Groton, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Gasolene-Engines, of which the following is a specification.

This invention relates to gasolene-engines of the type commonly used for furnishing a limited amount of power in launches and motor vehicles, my present purpose being to provide an extremely simple, strong, and serviceable crank-motion and guide for the same, all being described in detail hereinafter and illustrated in the accompanying sheet of drawings, in which Figure 1 is a central vertical sectional view of an engine-cylinder having mounted therein a piston and crank mechanism of my newlyimproved form. Fig. 2 is a side elevation of the said cylinder, the front wall being partly broken away to expose the crank mechanism. Figs. 3 and 4 are detached face and edge views, respectively, of the piston and crank connection. sectional view of the cylinder and crankplate, taken on line 4 4 of Fig. 1.

Referring to the drawings, the letter a denotes the cylinder proper, and a the cylinderhead, the latter being secured to the cylinder by screw-bolts 0. The cylinder at is provided near its lower portion with an annular flange a that is mounted upon and bolted to a like flange b, that is formed upon the upper end of a crank-chamber section b in such manner that when the parts are assembled, as in Figs. 1 and 2, the lower end portion of the cylinder is suspended in the said crankchamber.

0 denotes a crank-shaft that is mounted in bearings formed as hubs or bosses c c on the sides of the section b.

The piston-head is shown at d and may be of the usual or of any other approved form. Depending from said piston-head and preferably formed integrally therewith is a plate or frame 6, whosewidth is the same as the diameter of the piston-head and whose edge portions are formed as arcs of the-circle described by the bore of the cylinder at, so that said curved edges may engage and be guided In Fig. 5 I have shown a crossby the inner wall or bore of the cylinder as the piston moves upward and downward in said cylinder.

Bolted to the lower cross-bar e of the plate e is a bar f, and in the open space between said bar and the crossbar c is mounted to slide a traveler-block g, that is connected with the wrist-pin h of a crank it, which latter is keyed or otherwise secured to the shaft 0, already referred to. When the engine is in operation, each explosion in the upper end of the cylinder drives the piston and connected plate 6 downward and the traveler-block g imparts rotary motion to the crank and to the shaft 0, the crank-action being substantially that of the commonly known Scotchyoke type.

My described piston, piston -plate, and crank connection provide a very simple and strong construction, and one which I find in practice shows no appreciable wear and does not require frequent lubrication.

Having thus described my invention, I claim 1. In combination, a crank-chamber section, a cylinder mounted upon and depending within said section, a shaft revolubly mounted in said section, a piston in said chamber, said piston being formed with a depending plate whose opposite edges are curved to conform to and engage the bore of the cylinder, a bar secured to the lower cross portion of said plate, with a space between them, and a crank and a traveler-block movable in said space and connecting the said plate and shaft.

2. The combination with the crank-chamber section, of a cylinder detachably mounted thereon and extended therewithin, a piston movable within said cylinder, a plate depending from and in addition to said piston and movable in said cylinder, the width of said plate being the same as the diameter of the piston-head and having its edge portions formed as arcs of a circle described by the bore of the cylinder to conform to and be guided by the inner wall of said cylinder, a crank-shaft revolubly mounted in said section, and crank mechanism connecting said shaft and piston through said plate.

3. The combination with a crank-chamber section and a cylinder mounted thereon and extended into said chamber, of a piston movable in said cylinder, a plate in addition to and depending from said piston into said chamber, a cross-bar detachably secured to the lower end ofsaid plate, a traveler-block mounted to slide between said cross-bar and the lower end of said plate, a crank-shaft revolubly mounted in said crank-chamber section and connected with said block all m substantially as shown and described In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
