Recent Gas Engine and Motor Patents.

581.816. Motor Vehicle.-Robert J. Gibbons and Margaret A. Wilcox, Chicago, Ill. Filed March 14, 1896. Serial No. 583,220.

This relates to the transmission and control of the power in a motor vehicle. In this case a gas engine is assumed as the motive force, but any other source of power may be used.

The inventors claim that they have produced a motor-vehicle, which from the simplicity of the mechanism for starting, stopping, etc., can be managed without special skill or learning, and that the vehicle has great advantages accruing from the use of the variable speed gearing, especially in the quick way in which it answers any change of the operating wheel, and in its quick reversing, as the engine itself continues in its motion. Then by use of the automatic starter they provide a vehicle which is practically self-starting, and thereby are enabled to place all the operating parts in a complete housing, so that they will be unaffected by bad weather, etc.

In lieu of the valve for controlling the supply of gas and air to the gas engine a "controller" may be used to feed current to an electrical motor, and the shaft would then be used to operate this controller in a similar manner to that in which the valve is operated.

582,073. Gas or Oil Engine. -Frank S. Mead, Montreal, Canada. Filed Sept. 23, 1895. Serial No. 563,450.

Claim. In a gas or oil engine, a power cylinder, a working piston, an air-compression chamber, a spraying device, a connection from the working cylinder to the compression chamber, an independent connection from the working cylinder to the spraying device, a connection from the oil-supply tank to the spraying device, a direct connection from the aircompression chamber to the spraying device to supply the latter with compressed air, and a connection from the air-com

pression chamber to the oil-supply tank to force the oil to the spraying device by air-pressure, substantially as described. 582,108. Explosive Engine.-Alexander Winton, Cleveland, O. Filed March 18, 1896. Serial No. 583,840.

One object of this invention is to provide an explosive engine with a mechanism for using the exhaust for the backward stroke of the piston, thus producing a compound engine and a considerable increase in the power and efficiency thereof, and at the same time a muffle for the exhaust to prevent the usual noise therefrom.

Another object of the invention is to provide an air cylinder for controlling admission of air and gas, and thereby the force of explosion, power and speed of the engine.

A further object of the invention is to provide a feeding arrangement or mechanism for the fluid of gasolene or other similar engines to prevent flooding, and yet always insure an adequate supply of fluid for the working of the engine.

Claim. The combination with an explosive engine of a hydrocarbon feeder comprising a U-shaped pipe having one end open to the atmosphere, the opposite end in communication with the cylinder, a fluid supply at a point near the open end of said pipe, a fluid tank, a pipe opening into the air and fluid supply pipes at a point opposite the fluid-feeder to receive the excess fluid and deliver it to the tank, and a pipe in communication with the doubled portion of the U-shaped pipe and the tank, the parts adapted for the purpose described.

581,783. Gas Engine.-Thomas Small, Camden, N. J., assignor to George J. Richardson, trustee, Philadelphia, Pa. Filed April 11, 1896. Serial No. 587, 184,

Claim. The combination in a gas engine, of a cylinder having air and gas inlets, and a main exhaust port for exhausting the main portion of the products of combustion at the completion of each forward stroke of the engine, said port opening into the cylinder at or about a point coincident with the line of travel of the inner face of the piston when full forward, means for inducing the flow of an explosive charge into the cylinder at the completion of each forward stroke of the piston as the products of combustion are withdrawn from the cylinder, a piston in said cylinder, a high-pressure exhaust port to permit the escape of the products of combustion above the pressure of the atmosphere and an automatically operated one-way check valve provided in said port constructed to open before the main exhaust port is opened.

581,784. Gas Engine.-Thomas Small, Camden, N. J., assignor to George J. Richardson, trustee, Philadelphia, Pa. Filed April 11, 1896. Serial No. 587, 186.

Claim.-A double-acting gas engine having two alternatelyoperating power cylinders, each having a reciprocating piston, automatically-operated air and gas inlet valves provided at or near one end of the cylinder, high-pressure escape valve, an exhaust port for exhausting the remaining products of combustion, and simultaneously drawing in a new charge, means for automatically igniting the charge when under compression, a double-acting pump, the opposite ends of the cylinder of which are connected with the exhaust ports of the power cylinders respectively for exhausting the products of combustion at or about the time the reciprocating piston of each power cylinder approaches the lower end of its said cylinder or full forward stroke, crank-shaft and connecting-arms and parts connecting the respective pistons to the said shaft.

The Roser-Mazurier Motor.

A recent issue of La Locomotion Automobile gives a description of a novel motor in which the exhaust is utilized in a special cylinder, resembling a hot-air motor. It comprises two cylinders A and A1, constituting the petroleum motor proper and operating on the Otto cycle, and a third cylinder C of the same diameter. (See Figs. 1 and 2.) The burnt gases coming from the two cylinders at a high temperature are employed to heat a quantity of gas previously compressed in the hot-air cylinder C. This previous compression, it is claimed, increases the efficiency and prevents a sudden expansion when the burnt gases reach the cylinder C.

The cylinders A and A1 have admission valve c and c1 and exhaust valves d and d1, which conduct the burnt gases to the second motor C where the valve k regulates their admission. All these valves are mechanically operated by levers / and cams g acting upon friction rollers h (Fig. 3.)

The shaft has three crank throws at 90°, with balance weight P. It is désaxéo by contact with the cylinders with the object of avoiding back pressure.

The cams g, regulating the motor by their automatic action upon the different valves are mounted on a rod g moved by the pinions p, o, n, l, in connection with the motor shaft o (Fig. 2.) The pinion being twice as large as the pinion o, the cam rod 9 turns half as fast as the motor shaft. Hence an explosion is obtained, in each cylinder every other revolution, and motive impulse on the shaft every revolution.

The cylinders A and A1 exhaust alternately into the hot-air

cylinder C, which exhausts at every revolution through the valve e.

This motor is said to work equally well on gas, gasolene or kerosene, ignition being effected by the hot tube. Great economy is claimed for it, the inventors putting the saving at 30 per cent., the consumption of fuel not exceeding 300 grammes per hour per horse-power.

It is the intention to apply this motor to vehicles, and to this end a transmission by friction discs has been devised, represented in Figs. 5 and 6.

Three shafts, D, H, Q, are placed at right angles in the same plane, resting in four bearings. The shaft H carries two discs, the fixed discs I and the movable disc X guided by a key working in a groove.

To change speed the disc X is away from the centres of A and O. motion is reversed.

moved either toward or When the centre is passed

To disconnect the power the lever is thrown back, moving the disc away, while the two rods V bring the disc A out of contact. If the same lever is thrown further back the brake is applied, for the pulley A' then acts on the brake shoe B1 whose two extremities are fastened at B' and D1. To diminish friction the disc A is provided with ball bearings. As the disc I is loose upon the shaft and has a tendency to work away from the centre, one ball bearing is sufficient.

In a new construction, which the inventors have devised the hot air cylinder, will be placed between the other two in order to secure greater compactness. The three-horse motor, it is estimated, will then weigh only about 140 pounds..

The Flying Machine.

WE take pleasure in presenting to our readers in this issue an article from the pen of Mr. A. M. Herring, of Chicago, Ill., who for several years has been associated with Mr. O. Chanute, of the same city, in the study of the principles involved in the flying machine. His statement that motors of sufficient lightness and power for the propulsion of flying machines have already been produced, both for steam and gasolene, should silence those doubters who think a successful carriage motor an inventor's dream. The great difficulty yet to be overcome, however, is the changeable winds to which the machine must automatically accommodate itself to maintain its equilibrium. This is the task which the two Chicago aeronauts, in common with other

themselves. That they are able to report so much real progress in so short a time gives good ground for the hope that complete success is near at hand.

The Prevention of Noise.

AT last we are beginning to realize that there is a noise nuisance in our modern civilization, and a society known as the Society for the Prevention of Noise has been organized in New York to mitigate it.

The work is a most commendable one, worthy of the co-operation of all good citizens. The disastrous effect upon the human nervous system of the thousand and one discordant noises that make a Eedlam of a great city is not appreciated. The actual waste of time and strength due to this cause would foot up many millions of dollars annually, yet it seems to be accepted like scores of other nuisances and burdens under which the race groans as a necessary evil due to the multiplied activities. of our modern life.

Under

This is only partly true; noises may be generally divided into classes, useful and pernicious. the first class come the various warning signals which are found necessary for the protection of life in populous centers, and which, apparently, must grow in number as population increases and street locomotion keeps pace with its needs.

Of the pernicious noises the horse and the rough pavements provided for him are a most prolific source. The impact of horses' hoofs and the clash and clang of iron tires make up a large part of the disagreeable noises of a great city. Smooth pavements and motor vehicles running upon them will reduce this class of street noises to a minimum,
