AUGUSTE DESGOFFE, OF ODESSA, RUSSIA.

GOVERNOR FOR ENGINES.

SPECIFICATION forming part of Letters Patent No. 544,061, dated August 6, 1895.

Application filed November 10, 1891- Serial No. 411,525. (No model.) Patented in Belgium January 8, 1890, No. 89,115; in France January 23, 1890, No. 203,322, and in Italy May 20,1890,No. 27,538/81. v

and it consists of certain novel parts and combinations of parts, which will be specifically pointed out in the claims concluding this specification.

The following is a description of the gov ernor shown in the accompanying drawing;

but it will be understood that my invention is not limited to the precise devices and combination of devices here illustrated and described, as various modifications in the structure may be made without departing from the spirit of my invention and without exceeding the scope of the concluding claims.

' The drawing herewith filed illustrates a longitudinal section through a governor containing my present invention.

I will now describe the structure indicated in said drawing, which is one of the forms in which I at present prefer to embody my invention, while in the claims I will indicate the novel features of my invention and will specify the subject-matter covered by these Letters Patent.

2 is a base or bed-piece on which are set standards 3 3.

d is a shaft attached to any revolving part of an engine or other contrivance to which the regulator is applied.

5 is a piston keyed to the shaft 4.

6 is a cylindrical case provided with headpieces 7 and 8. The bottom head-piece 8 is provided with four perforated ears, two of which 9 9 are shown slipping over the standards 3 3 (only two of the four being shown) and free to rise and fall on said standards.

Each of the standards'o is surrounded by a spiral spring 10, which at one end bears upon the top of the ears 9 and at the other end against a collar 11, surrounding the standard 3, held in place by pin 12.

The head-piece 7 is provided with a pin having a screw-thread 13 on an enlarged section, forming a plugin the said head-piece and securing thereto an eye 14.

15 is a set-screw or plug stopping a hole in the cover 7. The cover 7 is provided with a flange, forming a ledge all around its top, to which a cylindrical envelope 16 is attached at one end. At the other end it is attached to a ledge on the bottom head-plate.

The space 17 is formed between the outer walls of the case 6 and the inner walls of the envelope 16. This forms an annular reservoir open to the air at 18.

The shaft 4 is bored at its upper end to receive the pin 19, provided with longitudinal groove 23, which, in connection with ears 9 and standards 3, form a guide for the case 6 as it rises and falls, as hereinafter described.

22 is a stuffing-bag surrounding the shaft 4: to prevent the escape of the fluid contained in the cylinder at the point where the shaft enters the case.

In certain applications for Letters Patent I have illustrated and described what I call the antispire systenyin which opposing surfaces, each provided with threads inclined in opposite directions, form, in general terms, the characteristic feature. To these specifications reference is here made for a fuller description of the general princi ples and features of structures operating on this principle. 1

- The piston 5 is provided with spiral threads 20 20, inclined in one direction, and the case 6 is likewise provided with spiral threads 21 21, inclined in the opposite direction, so that where the inclined surfaces are face to face these threads cross each other at a given angle, which angle, generally speaking, I prefer should be seventeen degrees forty minutes. As I have said before, the piston 5 is keyed to the revolving shaft 4, which is connected to any suitable moving part of an engine or other device to which it is attached, and, ac cording to principles fully explained in my said applications, it is obvious that if water, oil, or any other suitable fluid have free access ICO to the lower part of the case 6 the revolution of this piston will propel it against the upper head 7 of the cylinder 6 with a force proportioual to the velocity at which the piston revolves.

The operation of the device above described may be thus stated: The lower part of the cylinder-chamber 6 is filled with water, as is also the reservoir 17. This reservoir is open to the air at 18. Hence, the revolution of the piston 5, propelling the water against the cover 7, causes those parts of the structure to which the cover is attached to rise against the force of gravity and against the force of the springs 10 10. The elevation which it will reach is determined by the pressure of the water against the head, which in turn is determined by the speed at which the piston revolves. The eye 14 is connected, by suitable levers or other contrivances, with the valve controlling the admission of steam, gas, water, or whatever may be the substance operating the device, so that as the case rises the motive power is more or less diminished and as it falls the motive power is more or less increased. In this way perfect regulation of the speed of the device may be obtained.

It will be observed that in this regulator the use of all flexible or elastic parts is avoided, and that a non-elastic medium, such as water, glycerine, &e., is employed, so that every change of speed of the engine operates the governor, which instantly acts upon the valve controlled thereby. This governor is extremely sensitive and responds instantly to the slightest variation of speed of the engine controlled thereby. Indeed, its sensiti'veness is practically unlimited, owing to the fact that the oppositely-inclined grooves operate in a positive manner uponthe inelastic fluid under pressure. This regulator may be placed horizontally or in any inclined position. If inclined, preferably the annular reservoir containing the fluid should be in communication with a supplemental reservoir to supply it with such fluid.

The antispire grooves, their form, number, and dimensions, may vary according to the requirements of the device and they may be of any required inclination, although in general I prefer to give them, both on the piston and on the case, an inclination of seventeen degrees forty minutes. However, the opposite grooves need not have the same inclination. As is more fully pointed out in my said pending application, the essential relation between the grooves on the opposing surfaces is that they must form angles with each other, and it is not therefore necessary that the grooves of both surfaces have the same inclination.

In the foregoing specification I have described a few of the modifications which may be employed in the practice of my invention, but I have not endeavored to describe all the modifications which may be suggested, as the object of this specification is to instruct others skilled in the art to practice my invention in forms which are at present preferred, and to understand its nature; and it will therefore be understood that the mention by me of a few modifications is not intended to exclude others not referred to, but which are within the spirit and scope of my invention.

Certain details, illustrated and herein described, are not essential to the several features of my invention, broadly considered.

All this will be pointed out in the concluding claims, as the omission in a given claim of reference to an element, or the omission of reference to the particular features of the elements contained, will beunderstood to be a formal declaration of the fact that the omitted elements or features are not essential to the operation of the invention covered by said claim.
