ANTHONY ISKE AND ALBERT ISKE, OF LANCASTER, PENNSYLVANIA.

MOTOR.

SPECIFICATION forming part of Letters Patent No. 253,868, dated February 21, 1882.

, Application 'inea November 1, 188i. (No modela To all whom it may concern:

Be vit known that we, ANTHONY IsE and ALBERT IsKE, citizens of the United States of America, 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 appertainsto make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to motors which operate by the shifting of inclosed volatile liquid in 'vacuo from one chamber to another and higher chamber under the iniiuence of heat and its own gaseous pressure and by the gravin the same line, which improvement consists in the combination of an oscillating tube having at each end a receptacle for volatile liquid with acaloriic chamber or chambers into which these receptacles dip alternately.

The invent-ion further consists in providing each end of said tube with a.cover which extends over the receptacle at that end and which closes that side ofthe caloritlc chamber as said receptacle descends into it, thereby prevent ing waste of heat.`

The invention further consists in providing the calorifc chamber with a gate or analogous device and connecting the same with the os cillating tube aforesaid in such manner that the descent of either receptacle causes said gate to cut off the hot air entirely from the other receptacle and give the full effect of the cnr rent to the descending one.

The invent-ion consists, finally, in certain pealamp, B, or other calorilic device.

culiarities of combination and construction of the devices hereinafter set forth. A

In the accompanying drawings, Figure 1 represents a rear perspective view of ourimproved motor embodying the presentinvention. Fig. 2 represents a vertical section of the same, taken longitudinally through the axial line of the tube. Fig. 3 represents a front elevation, showing the pump-operating mechanism.

The same letters of reference designate the same part-s in all of the above figures.

.A designates a hollow casing, preferably of metal, which constitutes .the supportin g-frame for the motor and also incloses the caloric chamber. This casing is open at the bottom and also at each of its upper corners, these upper openings forming entrances a a for each of the receptaclesv hereinafter described. In the front of said casing, atthe bottom thereof, is a door, iA', for the insertion and removal of A V- shaped partition, A2, converging downward from the top of the casin g toward the lamp, divides the caloric chamber into two diverging passages or apartments, one extending from the lamp to entrancea and the other to .en trance a. On thek top of said casing aretwo standards, C C, which afford bearings for truun io ns c c', that are formed with Ya sleeve, D, rigidly secured on the middle part of a tube, E.

This tube is of' sheet metal or other stift' material, and has at its ends cylindrical recepta- The heat is thus prevented from escaping, and

also is reflected upon the top of said receptacle.

Trunnion c, before referred to, carries in front of its standard C a gear-wheel, G, which meshes with two racks, H H, formed. on the upper ends of piston-rods I I, which operate in pump IOC) cylinders J J, supported on a ledge, j, attached to the front of casing A. Of course any other form of mechanism may be operated instead of these pumps by said cog-wheel and pinion or by cranks or other suituable devices.

The other trunnion, c', which, if desired,'may be in one piece with trunnion c, forming a continuous shaft,) carries a crank-arm, 7c, which is connected by a long rod or pitman K to a erank-arm, l, on a rock-shaft, L, journaled in the front and rear walls of said casing A. This rock-shaft carries a depending gate, M, which Vibrates from side to side as the tube E oscillates on its trnnnions or transverse shaft.

rlhe operation of the machine is as follows: When receptacle E is within the calorific ch ainber and receptacle E2 at its highest point the gate M is in position to direct the entire body of heated air against the former receptacle. The liquid in this receptacle becomes partly vaporized 5 but as the end of the tube E is extended nearly through this receptacle the vai porized liquid is obliged to drive by expansion the remainder ot' the liquid before it through said tube in order to nd room. This results in transferring bodily and almost instantly the whole supply of fiuid from the lower receptacle to the upper one. The latter then preponderates, and therefore descends to becomethe lower in its turn. During this descent the trnnnioucranks and connecting-rod or pitman v 'above described cause shaft L to rock in the opposite direction, so that the gate M cuts oft' the hot air from entrance a and allows it to flow to entrance a. Receptacle E2 then passes within or through said entrance containing the alcohol, again liquefied by descending through scribed in the second of our earlier patents hereinbefore referred to.

Of course other forms of cut-olf. mechanism maybe substituted for the gate above described and its operating shaft-cranks and pitman. It is, however, a very convenient and satisfactory device for the purpose designed. Hot water may be substituted for hot air as a means of partial vaporization.

Of course the receptacles may be duplicated, or the tube, or both.

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

l. An oscillating tube having at each end a receptacle for volatile liquids and a cover, in combination with a caloritic chamber provided with an entrance for the admission ot' said receptacles, each entrance being adapted to be closed by the appropriate cover after the receptacle has entered.

2. In combination with an oscillating tube and a pair of receptacles for volatile liquid, attached to the ends of said tube, a calorific chamber divided into two parts or passages, and a gate or valve within said chamber connected to said tube in s uch manner that the oscillation of said tube cuts off the hot air from one of said parts or passages and directs it into the other.

3. In combination with tube E and terminal receptacles E' E2, the casing A, the gudgeons or pivot-shaft for said tube, rock-shaft L, gate M, and the cranks and pitman or connectingrod, whereby the oscillation of said tube is enabled to automatically control the vibration of said gate, substantially as set forth.

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