SPECIFICATION forming part of Letters Patent No. 366,958, dated July 19, 1887.

(No model.)

To all whom it may concern:

Be itknown that I, J ULIUs HERMAN HOLM- GREEN, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Improvement in Motors, of which the following is so full, clear, and exact a description as will enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, in which Figure 1 is a perspective of my improved device, showing the same attached to a sweep for running a drill, a vertical reciprocating saw, or a pump, or any device in which a re ciprocating motion is desired. Fig. 2 is a side elevation of my improved device. Fig. 3 is a front view of the same. Fig. 4c is a detail View of apart of an adjusting device used for adjusting the length of the stroke of the motor. Fig. 5 is a similar detail view of the serrated plate which meshes with the plate shown in Fig. 4 for forming the adjustment referred to.

The object of my invention is to construct a device which may be used for pumping, sawing, drilling, and other analogous purposes, which will be effective in its operation, and which will not be liable to get out of order, and the parts of'which will not be liable to get out of alignment with each other. To this end it consists in making the device triangular and mounting the fly-wheel on the shaft, which holds the upper end of the frame firmly to: gether.

Heretofore great difficulty has been experienced with devices of this ch aracterand great disadvantage has resulted from the wrenching and twisting of the parts and the frame, which resulted in lost motion and irregular movement, and my object is to obviate these disadvantages; and to that end it consists in construeting a frame triangular in shape, rigidly secured together, as will be hereinafter dcscribed,and the gear-wheels and the shafts upon which the same are mounted are to be mounted one directly above the other in the manner shown.

In the accompanying drawings, A A designate the main stays or side pieces, which are triangular in shape and which are bolted together at their lower extremities by the bolts or rods c a, and which are rigidly secured together at the top by the rod or shaft to. These stays are also provided with cross-braces A A.

which are in this instance formed integral with' the main stays. These cross-pieces are provided centrally with suitable journal-boxes, in which is mounted the shaft B. This shaft B is provided at one end with an ordinary knuckle-joint, O, and at its opposite end with a crank-arm, D, having a wrist-pin, D, to which is secured the lever E.

The rod a, which secures the upper portion of the frame rigidly in place, has looselyjournaled thereon a ily-whcel, B, the hub of which is provided with a pinion, B, which is rigidly secured to the fly-wheel B at its hub and may be formed integral therewith.

The fly-wheel may be flat to receive a belt.

The fly-wheel and the pinion B rotate to gethcr and are journaled on the rod or shaft a. Directly beneath the pinion 13 is a cogwheel, 0, which is rigidly keyed to the shalt B, journaled in the journal-boxes a" a, and this cog-wheel O imparts motion to the flywheel B through the medium of the pinion B. Motion is imparted to the device through the knuckle-joint O, which is connected in any suitable manner with a rotating rod, which may be run by horse-power, water-power, or

any other suitable motive power which it may be found desirable to use.

The crank-lever D is adjustable by' means of the corrugations D (shown in detail in Fig. 5,) and the two plates 1) D may be bolted together at any desired adjustment through the perforations d d and by a suitable bolt, (1, (shown in Fig. 3.)

From the foregoing it will be observed that the device is constructed triangular in shape and is securely and firmly held in place by rigid rods at its three extremes, which makes a very strong and compact device. In this instance the whole device is constructed of metal, the fly-wheel and pinion B being rig idly secured together and journaled loosely on the rod or shaft to in the top of the frame, making a device in which. the friction is comparatively slight.

It will also be observed that the main rods or shafts supporting the running-gear are mounted in the frame one directly above the other, thus preserving the center of gravity 1. In a motor of the character described,

the combination of the main stays made triangular in shape and rigidly secured together at their three extremes, the rod at the top of the motor which serves as a stay for the frame and forms a bearing for the fly-wheel, which is journaled loosely on said rod, a pinion formed rigidly with the fly-wheel, and a second rotating shaft journaled loosely within the frame directly beneath the fly-wheel and pinion, said rotating shaft having a gearwheel which imparts motion to the pinion and fly-wheel, all constructed to operate substantiall y as and for the purposes specified.

2. The main frame made triangular in outline and provided with two cross-beams midway between the extremities of the side pieces, and a rotating shaft journaled between the side pieces and within suitable journal-boxes, said rotating shaft having a joint at one end and an adjustable crank-arm at the other, and a cog-wheel rigidly secured to the shaft, with a fly-wheel and its pinion journaled loosely on the rigid shaft in the top of the frame, all constructed to operate substantially as and for the purposes specified.

In testimony that I claim the above as my invention Ihereunto set my hand in the presenee of two subscribing witnesses.
