EDMUND WISEMAN AND JOHN HOLROYD, OF LUTON, ENGLAND.

HYDROCARBON-MOTOR.

SPECIFICATION forming part of Letters Patent No. 600,107, dated March 1, 1898.

Application filed May 27, 1897.

To all whom it may concern.-

Be it known that we, EDMUND WISEMAN and JOHN HOLROYD, subjects of the Queen of Great Britain, residing at Oheapside, Luton, in the county of Bedford, England, have invented certain new and useful Hydrocarbon-Motors, of which the following is a specification. r

The objects of this invention are to obtain a more perfect mixing, heating, and combustion of the charge, the prevention of fouling, a more regular supply of the hydrocarbon, and a ready means for starting the engine.

Figure 1 is a central longitudinal vertical section, Fig. 2 a transverse vertical section on the line 22, Figs. 1 and ,3, and Fig. 3 a plan, of so much of a motor as is necessaryto illustrate this invention. Fig. 4is a vertical longitudinal section, and Fig. 5 an end elevation, of the oil-supply apparatus. Fig. 6 is a side elevation, and Fig. 7 an under side view, of the lamp or burner Z. Figs.'8 to 11 show a modification. Fig. Sis a side elevation, and Fig. 9 a plan. Fig. 10 is a section on the line 10 10, Figs. 8 and 9; and Fig. 11 is a horizontal section on the line 11 11, Fig. 10.

a is the cylinder, carried on the hollow bed I), which forms an air-reservoir.

b is a pipe passing through the reservoir I), having an air-admission valve 19 at its lower end and a branch pipe 19 near its middle, with an emission-valve 6 leading into the reservoir b.

' a. a a a are annular passages formed in the walls of the end of the cylinder.

0 is a pipe opening into the reservoir Z2 and having two branches. 0 0 leading, respectively, into the annular passages a and a d is a pipe leading from the annular passage a to the end of the pipe 0, whose other end is open to the cylinder, and f is a valve between the two pipes.

g is a pipe leading from the annular passage 0t to the pipe (1, just below the valve f, and h is a valve on the pipe 9.

j is a casting on the top of the cylinder at and having within it a circuitous passage j, having its ends connected to the annular passages a and a is is the oil-supply apparatus. (Shown to a larger scale at Figs. 4 and 5.)

Air from the reservoir 12 is led by the pipe 0 to the annular passage a, in which it becomes heated, and then enters the circuitous passage j, at the commencement of which it meets with the oildelivered by the measurer k. The oil and air pass together through the circuitous passage j, the annular passage 01?, and pipe to the valve f, the vaporization of the oil being completed in traversing these hot passages. At the Valve f the hot mixture of air and vapor meets a supply of air led from the reservoir b by the pipe 0 into the annular passages a a in which it becomes heated and from whence it is conducted by the pipe (1 to the valve f. Z is' the lamp. Figs. 6 and 7.)

m is the exhaust-port, leading to a chamber in which there is an exhaust-valve n and an air-admission valve 0. The valve n is opened once in every two revolutions of the crankshaft by any ordinary gearing, which is not shown. The valve 71. is operated by the governor in the usual way, so that the supply of hyrdocarbon vapor is stopped when the engine is running too fast. The valves f and o are operated by the suction of the piston; but they may also be aoted'on by the governor to prevent the cooling of the engine when running light.

In Figs. 4 and 5, 7c is a reservoir having within it a conical shell through which are two diametrically opposite horizontal holes, one leading into the reservoir and the other to the air-pipe 70 and also two vertical holes, one leading to the bottom of the air-pipe it, connected to the reservoir 6, and the other to the top of the pipe is, leading into the passage j, Fig. 1. k is a solid conical plug in the shell k and having a hole passing diametrically through it, alternately connecting 70 with 70 (Shown to a larger scale at when the oil enters it and 71: with 16 when the oil is sucked out of it by the outstroke of the piston. Wis a spindle fixed to the plug 716 and carrying a pinion or quadrant k gearing with a pinion or quadrant it", to which an oscillating motion is given by means not shown. 10 is a collar fixed to the spindle is, and 70 a collar loose on it. 10 is a spring tending to force the collars 10 and Z0 apart, and so keep the plug 10 tight in the shell k 70 is a screwcap closing the end of the shell k and 70 is a hole admitting air to the top of the reservoir 7a.

In the lamp or burner shown at Figs. 6 and 7, Z is the base-plate, screwing onto the top of the pipe 6, Fig. 1, and Z is a passage formed in it which is connected to an oil-supply pipe Z and to the nozzle Z is a regulating-needle in the nozzle. Z is a tube fixed to the baseplate, and Z is a diaphragm of wiregauze in it.

In starting the engine the axial pipe or annular ohamber,or both,are heated in any convenient manner, and then as soon as the hydrocarbon in the passage Z vaporizes the burner lmay be ignited to assist in the heating of the engine, so as to obtain an earlier start. It is also used to maintain the heat of the engine when running light or during stoppages. In ordinary work, however, the engine is selfiigniting. The lamp Z may either be fixed to r the top of the axial pipe, as shown, or to the bottom.

The engine shown is designed to work with a four-stroke cycle, the instroke of the piston after an explosion sweeping out the products of combustion through the exhaust-port m and valve 77., which is automatically opened at this time. The ensuing outstroke draws in a heated mixture of hydrocarbon vapor and air through the valve f and of air through the valve 0. The next instroke compresses the charge, which automatically ignites and so completes the cycle. Some of the improvements are, however, applicable to engines working with other cycles. The reservoir 1) may also be dispensed with and the engine be made with an open-ended cylinder. In this case the pipe M, Fig. 4, is open to the outer air.

In the modification shown at Figs. 8 to 11 the annular passages a, 0. and a for heating the air are replaced by other ordinary means, and the block or casting j, containing the circuitous passage j, is brought into direct contact with the cylinder. In this case the air heated by the exhaust or otherwise is admitted at f directly to the valve f, while the oil (and, it may be, some air also) is led by the pipe from the nozzle 70 of the measurer, Figs. 4: and 5, which is not shown, into the circuitous passage j and from thence passes by the annular passage a into the pipe 9, made in one piece with the pipe 6, to the valves h and f and so to the cylinder.
