ANTHONY ISKE AND ALBERT ISKE, OF LANCASTER, PENNSYLVANIA, ASSIGNORS OF ONE-FOURTH TO ISRAEL L. LANDIS, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 242,454, dated June '7, 1881.

Application filed February 8, 1881. (No model.)

To all whom it may concern:

Be it known that we, ANTHONY IsKE and ALBERT IsKE, citizens of the United States, residing at Lancaster,in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Motors; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specificatiou.

The object of this invention is to provide a new and improved motor, by utilizing the principle of the pulse-glass or pulsometer, for the working of machinery and other purposes.

In the accompanying drawings, Figurel represents an elevation of a wheel embodying our invention, and Fig. 2 represents a detail view of one of the alcohol-tubes attached thereto.

A designates the hub of the wheel, and B a series of tubes attached thereto at the middle part of each tube. These tubes are provided at their ends with bulbs b b, the bulb b at one end of each tube being turned in the opposite direction from the bulb b at the other end thereof.

0 designates a lamp or other calorific device arranged under said wheel, so as to heat the bulbs when they reach their lowest position. Said tubes are partly filled with alcohol or other volatile liquid, and the air is exhausted from the interior of said tubes by an air-pump, or any other well-known and convenient means, after which the tubes are closed, as in the case of the ordinary pulse-glass.

As each bulb comes above the fire at the lowest point of its revolution it will receive sufticient heat therefrom to vaporize a part of the alcohol orotherliquid, which, pressing upon the remainder of the alcohol in said bulb, will force it up through the tube and into the other bulb. When the amount of liquid in this latter bulb outweighs the amount in the bulb next the heat, the former will descend and the latter will ascend, giving to the tube, as a whole, a rotary motion about its middle point. This action is repeated as each bulb of the different tubes is successively presented to the heat, and in consequence the wheel to which they are attached is kept in continuous rotation. The flow of the liquid from bulb to bulb is Very rapid, and the momentum of the wheel prevents even the slightest stoppage or delay.

Of course, any suitable substance may be substituted for the glass commonly used in tubes of this sort, and the size and general construction of the motor may be varied at will.

The above description presents simply a very convenient form in which we have embodied and applied our invention 5 but we do not wish to be confined thereto. The same principle maybe utilized in constructions differing considerabl y therefrom, though effecting the same result and coming fairly within the scope of our invention. For example, a disk may be provided with tubes which have bulbs at both ends, but on the same side of each tube, the disk or wheel, as a whole, being inclined at an angle of about thirty-five degrees. Also, we may use a conical drum, or a large wheel and a small wheel corresponding thereto, said wheel or drum having tubes attached to them in an inclined position, and each tube having one or more bulbs on each end, two heaters being used.

In almost all cases there is a decided advantage in having the bulbs on opposite sides of the tubes, and thisis absolutely necessary when the rotation is in a vertical plane, as first described. Otherwise each bulb would reach a point where the pressure of the vaporized liquid would not operate to drive the liquid through the tube. Moreover, there would be nothing to cause one end of the tube to tilt downward and the other upward, so as to give the continuous rotation desired.

When the wheel form of motor (that shown in Fig. 1) is used, I ordinarily employ a troughshaped reflector curved ,longitudinally to the shape of a quarter-circle, and arranged just inside of that fourth of the wheel where the heat is to be applied, so as to be over the bulbs from the time they reach their lowest position until they reach the end of the first quarter of their rotation. This reflector is designated by the letter E, and preferably made in two longitudinal halves, one of which is shown in Fig. 1.

It isslotted longitudinally along its convexity or arch, to allow the passage of the stems of the tubes as they rotate. Its edges and concavity are presented outward and downward. Its office is to concentrate by reflection the heat of the calorific device 0 upon the bulbs, and thus increase the eflicacy of said device, and of the motor itself.

Other forms of heat directors, reflectors, and the like may be used for a similar purpose, and with other forms of motor.

A current of cold air may be directed on the bulbs at one side of the wheel and a current of warm air on the other side.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A motor consisting of a tube or tubes having a bulb or bulbs at each end, and provided with liquid arranged to be vaporized and driven from bulb to bulb on the principle of the pulse-glass.

2. A tube containing volatile liquid and having a bulb at each end, said bulbs being on opposite sides.

3. A wheel provided with a series of alcoholtubes having a bulb on each end, but on different sides, as set forth, in combination with a calorific device applied under said wheel.

4. The method of operating a motor, consisting of forcing a vaporizable inclosed liquid, by the action of heat, into an upper space from which the air has been exhausted, and using its weight and downward motion, as set forth.

5. In combination with a calorific device and a motor operating by heat and gravity, substantially as described, a heat director or reflector, operating to throw the heat of said device on the bulbs of said motor, for the purpose set forth.

6. The combinationotcurved concave trough E with a tube or tubes having bulbs at each end and containing volatile liquid, said tube or tubes being arranged and adapted to operate as a motor.

In testimony whereof we atfix our signatures in presence of two witnesses.
