SPECIFICATION formingpart of Letters Patent No. 237,728, dated February 15, 1881.

Application led June 29, 1880. (No model.) .4

To all whom it may concern:

Be it known that I, BENJAMIN F. CARD, of

, the city of Brooklyn, county of Kings, State of 'N ew York, have invented a new and useful Improvement in Motors, of which the following is a specification.

This invention relates especially to that class ot' motors in which the vapor of bisul-z phide of carbon is utilized to obtain a force or pressure.

It is a well-known fact that the material referred to is a powerful solvent-of the oils or. fats generally used for lubricating purposes, while it evaporates quickly at ordinary tem` peratures, and to these properties thereof is due mainly the failure of its successful introduction into use up to the present time. In other words, all motors permitting the use of a vapor, as of bisulphide of carbon, demand the liberal use of lubricants to overcome friction,or are productive of loss or waste by the escape of thevapor.

The general object of this invention is to ob-l tain a motor adapted to the successful and economical use of the vapor of bisulphide of carbon-namely, by the combined effects. of minimum friction and a maximum confinement of the vapor.

This invention is illustrated in the accompanying drawings, in which Figure l represents a vertical section. top View, partly in section. Fig. 2it is a detail view of the supply-valve. Fig. 3 is a horizontal'section on the line x m, Fig. 1. Fig. 4 is a similarY section on the line y y, Fig. l. Fig. 5 is a vertical section of the vaporizing-chamber. Fig. 5* is a side view of the drivingwheel. Fig. 6 shows a modification of the core of the vaporizing-chamber, corresponding to Figs. 8 and 9. Fig. 'i' is a detail view of the cut-oft'. Figs. S and 9 show a modification of the invention.

Similarletters of reference indicate like parts in all the figures.

rlhe letter A designates a chamber, to which the bisulphide of carbon is admitted. For the admission of the bisulphide of carbon to this vaporizing-chamber A, I make use ot' a valve, B, which is arranged at the top of such chamber, and constructed with triple ways a, more Yor less, (see Figs. 2 and 2*, whereby steam or atmospheric air, or both, may be admitted Fig. 2 is a plan or alternately with the bisulphide of carbon. The shape of the vaporizing-chamber A is that of an annulus, and into the same is fitted a driving wheel or drum, O, which turns on a vertical axis, as hereinafter more fully described, and which is constructed, essentially, ofia series of blades, bent or curved substantially similar to those of a turbine, such blades be' ing connected together at the top and bottom by suitable heads or rings, with the spaces beltween them left open orfvacant.

Communicating with the vaporiZing-chamber A is a condenser, D, through which a stream of water or other liquid is kept running by means of pipes a a. for the condensation ofthe vapor, while between thevaporizin gchamber and such condenser is interposed a cut-off, F. This cut-off consists of disks b b, one of which has ports b', (see Fig. 7,) arranged in a circle concentric to the disk, while the other is constructed with gates b2 for closing the ports. In the example shown the number ofthe gates b2 is unequal to that of theports b', so that the two do not register with each other in any position of the cut-oft' disks, and it follows that the communication between the vaporizing-chamber A and condenser D is never entirely cut-off. If desired, however, the ports and gates b b2 may be so arranged as to be capable of registering with each other.

One of the cut-oftdisks b b constitutes the lower head or ring of the driving-wheel O, and hence it partakes of motion of such wheel, while the other disk is a iixture of the partition-platebetween the vaporizing-chamber A and the condenser D, as shown in Fig. 1, so that it is immovable; or it is attached to the core Gr of the vaporizing-chainber, as shown in Fig. 8, where such core is movable or arranged to turn, as hereinafter more fully described.

Surrounding the vaporiZing-chamber A is a heating-chamber, O, to which are connected pipes c c, for the admission and discharge of steam or other heating agent. v

On the inner surface ot' the wallv ofthe vaporizing-chamber A is formed a series of blades,

In the example shown in Fig. l, the core Gr.'

of the vaporizing-chamber is fixed, the same being secured to a rod, H, rising from the bottom of the condenser D, and the drivin g-wheel C is mounted on a shaft, I, projecting therefrom in opposite direction, the lower part of' such shaft being tubular, and being stepped in a block, do, at the base of the rod H, which latter passes through it, while the upper part of such shaft passes through a stuffing-box, c, at the top of the vaporizing-ehamber.

In the example shown in Figs. S and 9 the core G of' the vaporizing-chamber is secured to a shaft, I', while the driving-wheel C is mounted on gudgeons I2, the lowerone ot' which turns in a block, d', resting on the bottom of the condenser D, and constitutes a step for the lower end of the shaft I', while the upper gudgeon is a fixture of a bevel-wheel, J, which is geared with a similar wheel, J', keyed on the shaft I by means of wheels J2.

On the surface of the core Gr of the vaporiZing-chamber is formed a series of blades, c, which extend in longitudinal or vertical directions when the core is fixed, as in Fig. l, and which are bent or curved, but in opposite direction to the blades of the driving-wheel C, as clearly shown in Fig. 6, when the core is lnovable, as in Figs. S and 9.

On the upper or outer portion of the shaft I or Il is mounted an eccentric, K, having a rod,j`, whereby it is connected to a rock-shaft, N, carrying the supply-valve B to the vaporizing-chamber, so that an oscillating motion is imparted to this valve by lneans of the shaft.

rlhe ways a ofthe supply-valve B are arranged in the are of a circle of which the roekshaf't N is the center or axis, and hence such ways are alternately brought into play in the motion of' the valve.

In the condenser D is arranged an agitator, I), consisting of bars which are attached either to the lower part of the shaft I, as in Fig. l, or to the lower gudgeon, I, as in Fig. S, and which carry arms z, projecting downwardly therefrom.

In applying the apparatus to use, bisulphide of carbon, together with steam or atmospheric air, or both, arc admitted to the vaporizingchamber A, wherein the bisulphide of carbon at once takes the form of vapor, which impinges against the blades of the driving-wheel C, and imparts to the latter a rapidly-revolving motion. The action of the steam admitted to the valiorizing-chamber A is to heat said chamber, and to increase the expansive properties of the bisulphide of carbon, while that of the air is to intensify such action. After the vapor has exerted its force on the drivingwheel C it escapes into the condenser D, wherein it isfat once condensed or reliquefied, together with the steam, and whence it esscapes with the water through the pipes a. The escape ofthe spent vapor from the vaporizing-chamber A to the condenser D is regulated bythe cut-off F. The vapor is caused to take a downward course in the vaporizingchamber A, and is reflected upon the driving- Wheel C through the medium of the vertical channels formed therein by the blades d on the wall, and also by the blades c on thecore of such chamber when the blades last named are arranged as in Fig. 1.

When the blades c are bent or curved and the core of the vaporizing-chamber is arranged as in Figs. S and 9, the vapor has a like effect on the core as on the driving-wheel C, the niotion ofthe core, however, beingin an opposite direction to the driving-wheel.

The, effect of the heating-chamber O is to prevent waste or loss of heat from the vaporizin g chamber A by radiation, While the action of the agitator P is to produce waves on the water flowing through the condenser D, and thus to increase its cooling-surface, a revolving motion being imparted to the agitator by its support.

It should be remarked that my apparatus is capable of other modifications than those herein described, one such modification being to make the block d and rod H and core G tubular, and the upper end of the core Gperfor-ated with small holes, so that the bisulphide of carbon or other liquid or vapor may be inliected into the vaporizi11g-chamber A when the apparatus is arranged as in Fig. l.

IVhat I claim, and desire to secure by Letters Patent, is-

1. In a motor, the combination of a vaporizing-ehamber, a driving-wheel fitted in to such chamber, and a condenser communicating therewith, the whole constructed and adapted to operate substantially as described.

2. In a motor, the combination of a vaporizing-chamber, a supply-valve to such cham'- ber having triple ways, more orless, a drivingwheel fitted into the vaporizing-chambcr, and a condenser communicating therewith, the whole constructed and adapted to operate substantially as described.
