' applicati@ inea septembegio; 192s. serial im. 305,070.

This invention pertains generally togovernors and particularly to a-governor adapted for use with a iiuid engine, and'is a modication of the structure disclosed in my coending application Serial No. 271,492, led pi'il An object of applicants invention is the production of a governor for a fluid engine whereby the fluid passing into the engine is regulated to control the speed of the engine.

Another object of the invention is the production of a governor which is adjustable so that the maximum speed of the engine may4 be increased or diminished as desired.

, A further object of the invention. is the production of a device wherein the controlhingi mechanism is actuated by the moving provision of an auxiliary valve to'v relieve the drop 'across vthe device under certain conditions.

A further object of the invention is the production ofL a device of this kind which is simple in construction, of a small number of parts, easy to. manufacture, durable, reliable and highly satisfactory for its intended purpose.

Many other objects and advantages ofthe construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end lmy invention consists in the novel construction, arrangement and combination of parts herein shown and described and more 'particularly pointed out in the claims. f7

Applicants device includes a plate or disk having a plurality .of radially extending spokes and a second plate axially aligned with and movable relative to said irst-ingentionedv plate, and also having a plurality of projecting spokes preferably the same in .number as the spokes of the first disk. The spokes are made of substantially the same width as the open spaces therebetween, and means is provided for rotating the rst disk so as to` brin the spokes and intervening spaces into an out lof alignment with the corresponding spokes and intervening'spaces of the second- Still another object of the invention is the mentioned plate. The maximum speed of the engine is regulated by bringing the spaces between the spokes of the two disks or plates into and out of complete register. The disks are either in contact or in close proximity at the greatest speed of the engine, and the registering spaces between the spokes of the rel v spective disks provide passageways for the iow of uid past the disks. An auxiliary valve is provided to relieve the drop in the 6o pressure across the governor at certain speeds of the engine.

In the drawings, wherein like reference chzla'acters indicate like or corresponding pa s:

F1 2 is a sectional elevation of the same showing the governor connected to passages leading from the carburetor and to the engine Fig. 3 is a section on line 3-3 of Fig. 1;

Fig. 4 is a section on line 4--4 of Fig. 2;

Fig. 5 is a view of the immovable disk or plate; and

Fig. 6 is a view of the` movable disk or plate. l 75 Referring no'w to the drawings, the numeral 1 indicates a overnor which includes a casing 2 mounted tween a tubular member 3 leading from the carbureter and a tubular member. 4 leading to the engine. The casing 80 2 is attached to the tubular members 3 and`4 by means of bolts 7 extending through flanges 5 and 6. A support 9 extends across the passage 8 of the cas1ng2 and is provided with an enlargement 10 at its mid portion. A bore 85 11 extends through the enlargement 10 for the accommodation of a stem 12 which is attached to a movable disk or plate 13. A resilient member 14 is positioned between the disk 13 and the enlargement 10. A stop 15 90 comprises a burr which threadedly engages the stem 12 and is normally in contact with the enlargement 10, thereby limiting the movement of the disk 13 under the force of the resilient member 14. The casing 2is pro- 95 vided with a shoulder 16 which is engaged by a disk 17, said disk being held in position by a sleeve 18 disposed between the disk and a face of the casing 2. The stem 12 andspring 14 pass through an aperture 33 at thecenter 10 of the disk 17. The sleeve 18 is held in position by the flange of the tubular member 3 and is preferably provided with oppositely disposed recessed projections 19. The projections 19 are each provided with a recess 20 which form guides for projections 21 which are oppositely disposed on the movable disk 13. The recesses 20 form runways for the projections 21which permit the disk 13 to move in the direction of the longitudinal axis 3f 1its stem 12 but prevents rotation of the The casing 2 is provided with a hollow projection 22, the hollow portion 23 of which accommodates a projection 24 from the disk 17 The disk 17 is adjustable circumferentially by means of screws 25 and 26 which threadedly engage opposite sides of the projection 22 and abut opposite sides of the proection 24 on the disk 17.\

The disk 13 is providedwith a recess 27 into which open a plurality of converging channels 28 which have openings spaced about the stem 12. A recess 29 within the stem 12 accommodates the stem of a valve 30.A The valve 30 is provided with a spring 31 where, by the head of the valve normally engages a valve set at the end of a tubular member 32 which is positioned within the aperture 27.

30 When the valve 30 is opened,'the channels 28 establish communication between the carburetor side and the engine side of the governor forming a vacuum release opening.

The disk 13 comprises a central solid hub 35 portion to which the stem 12 is connected. A plurality of spokes 3rradiate from the hub portion of disk 13. he spaces 36 between the spokes 35 are preferably of substantially the same width as the corresponding por- 40 tions of the spokes. The disk 17 comprises an outer rim portion from which a plurality of spokes 37 radiate inwardly. The spokes 37 terminate short of the center and form the boundary of the aperture 33. The spaces 38 between the spokes 37 `are substantially the same width as that of the adjacent portions of the spokes 37. The disks 13 and 17 each have the same number -of spokes and the spokes 35 of the disk 13 are substantially of tle same width as the spokes 37 of the disk Each space 36 of the disk 13 is in alignment with a corresponding space 38 of the disk 17 to form a passageway through the disks for the fluid, said passageways having their maximum capacity when the spaces and spokes are in exact alignment. The fiow` of the fiuid through the spaces 36 and-38 operates to force the disk 13 toward the disk 17 aqgainst the resistance of the. spring 14.y The disks 13 and 17 are broughtinto contact or into close proximity by the flow of fluid when the fmotor reaches its maximum speed. The

A spokes 36 and 38 being in alignment and thev 6 disks 13 and 17 in contact provides the condition by which the maximum flow of fluid is attained. By turning the screws 25 and 26, the disk 17 may be rotated so that the spaces 36 and 38 are only partially in register thereby restricting the size of the passageways and the possible flow of fluid therethrough. It is obvious that by thus narrowing` the registering portions of the spaces 36 and 38, the flow of fiuid through the engine can be controlled at will and is made adjustable over a very large range. At low speeds of the engine the flow of the fluid through the device is not substantially affected by an adjustment of the disk 17. The effect of adjustment of the disk 17 becomes more pronounced, for speeds near to the maximiun which is the casevwhen the disk 13 is in close proximity to the disk 17. In canse the load on the motor is increased when operating at maximum capacity, the speed of the motor tends to reduce and demand more power for the motor to maintain the maximum speed under the increased load. The valve 30 opens and instantaneously reduces the drop across the governor by releasing disk 13 from disk 17, thereby permitting a larger flow of fluid to the engine. Without the valve 30 the speed would have to be substantially reduced before the disks 13 and 17 would be sufficiently separated to reduce the efi'ect of the restricted passageway.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
