HERMAN W. MARTIN, OF ILION, NEW YORK.

` MULTIPLE MOTOR.

SPECIFICATION forming part of Letters Patent No. 756,513, dated April 5, 1904.

Application filed March 2, 1903. Serial No. 145,729. (Nc model.)

To a/ZZ whom t `may concern:

Be it known that I, HERMAN W. MARTIN, residing at Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in MultipleV Motors, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to a multiple motor for the use of gasolene and the like; and I do declare that the following is a full, clear, concise', and exact description thereof, sufficient to enable one skilled in the art to make and use the same, reference being had to the accompanying drawings, in which like letters refer to like parts throughout.

My invention includes the arrangement of cylinders and operating parts connected therewith in juxtaposition and in their attachment to one main shaft or transmission device employing few parts in a simple construction and arrangement which permitsA ready access for repairing and adjusting the same, but at the same time produces a structure which has an advantage in power and.

steadiness in operation, together with other features.

My object is to produce a simple, cheap, compact, durable, and powerful engine with parts of simple and cheap construction so connected as to be readily adjustable and detachable for cleaning, replacing', or repair, one that is also of peculiar steadiness and smoothness in its operation and in which the length of travel in the pistons may be adjusted to the best advantage or the intermediate space be made different in the different cylinders, also in which the moving parts are steadied and supported in their operation by their close connection with and support and bearing upon the main castings of the engine.

In the drawings, Figure'l is a side view of my engine, and Fig. 2 is an end view. Figs. 3 and 4 are the top and bottom parts of a casing which I provide to inclose certain parts of the motor.

Referring to the gures in detail, I provide casting A, which is of suitable form and dimension for use as a cylinder. It has with it, integral or otherwise, a base-plate B,which extends a suitable distance outwardly from each end of the cylinder. It has also integral therewith the housing C, which extends from the body of the casting upwardly, presenting a general arch-like outline when viewed from the side, but which rises in companion parts, one on either side, so that there is a space between for the parts to be described. The top portion of this housing is prepared to receive a like part of a similar casting, such two parts being illustrated as fastened together on the line This similar casting A has its housing C', which is of the same general form and is made with duplicate parts, as is the housing of the lower cylinder, being likewise suitable for use as a cylinder and both of the parts A and A being properly finished to carry the piston-heads, which are not shown, but which travel on the inner ends of the piston-rods D and D. It will thus be plain that the type of engine whichI represent is that known as the center-explosion, wherein two pistons in two cylinders -are forced outwardly by a center explosion between them. I do not, however, show in this application the particular igniting device, as such is well known and can be applied by one skilled in this art.

As before stated, the housings O and C are provided with finished surfaces, so that one housing can be brought snugly against the other to hold one piston above the other,'as illustrated here. The two housings are then secured by bolts and nuts, (illustrated at c c.) On the lower casting I provide integral lugs a, and on the upper housing I provide integral lugs a. The lower lugs are tapped to receive the threaded bolts E, and near the lower ends of which are the nuts e. The upper lugs o are bored or tapped to receive the upper ends of the bolts E', which are secured therein by nuts e. By this arrangement I assist in firmly holding the upper and lower castings A and A in an exactly correct position, and I can adjust that position so that the operating parts will work smoothly and can take up any looseness in the connection in the housing and provide for any adjustment which may be made necessary after the machine has been used and still hold the cylin- IOO ders and housings as firmly together as though they were integral.

From the upper cylinder I extend horizontal arms F', which are bolted at f' onto the cylinder and are curved at their outer eX- tremity to carry the wheels f, which are made with a concave periphery to support the outer ends of the piston-rods D' in their play. From the lower cylinder I likewise extend horizontal arms F, which may be integral with or bolted to the casting A in the manner of arms F' and which carry on their oute1 end similar wheels f, employed for similar purpose. Of course the standards F and F' may be integral or otherwise with A and A', and the base B may be integral or otherwise with the casting A, though F and F' are preferably not integral withA and A', so that they can be'removed and the pistons readily drawn out. On the piston-rods D', I secure thel piston-rod arms G', and on the piston-rods D, I securethe piston-rod arms G, the free ends of those piston-rod arms located at one end or the other of the cylinders being brought together and secured by bolts g and g'. The ends of these piston-rod arms are made to support the ends of the crank-arms H in ordinary bearings, except that I cause the end of each piston-rod arm to overlap the end of the other piston-rod arm in its pair, so that by the bolts securingthem I can take up any wear and make at any time the necessary adjustment for the proper and free play of all the parts. rIhe pistonrod arms .G and G' may, however, be made integral with a longitudinal slot extending upward and downward from the bearing of the crank-arm H, in which case I still employ the bolts g and g'.

At y I illustrate one manner of holding the crank-arm on the piston-rod arm by an adjustable collar.

The housings C and C' are fashioned at their contiguous edges to furnish a bearing for the main shaft I, which is supported on each side of the engine by the housings and which has the cranks t' c'. About one end of the crank-shaft I provide pinion J, which engages the toothed wheels K and K', which are 'seated on the shafts 7c and 7c'. On the shaft I is also seated the balance-wheel L, which, however, in Fig. l is shown in broken lines. On each crank is mounted one end of each crank-arm H, the other end being, as stated, supported or connected to the piston -rod arms. The cylinders and other parts may of /course be duplicated as desired.

The toothed wheels or gears K and K' are employed for actuating the valves and other parts connected with the feeding and igniting devices; but Ido not here disclose the particular means I employ, as familiar forms and parts can be used for'such purposes.

I provide a casing to inclose parts of the motor whereby it is self oiling and clean. It

is comprised of two parts X, the lower` of which is of such form as to inclose the lower piston-rods, the main shaft, and the crank-arms. Around its upper edge it has inward corrugated line on which the upper part of theY l.
