IMPROVEBEENT -INAG-OVERNORS FOR STEAM A-ND OTHER ENGINERY.

The Schedule referred to in these Letters Patent and making part of the same. v

To all whom it may concern Be it known thatI, J osnrn THEoDon Losser, of Wrzburg, in the Kingdom of Bavaria, have invented a new and useful Improvement in Power-Regulators; of which the following. is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of. this specication, in which- Figure 1 represents a sectional elevation of a powerregulator constructed in accordance with my improvement, and

Figure 2, a plan of the same.

Similar letters f reference indicate corresponding parts.

This, my improved power-regulator, which is applicable as a governor to control the throttle-valve of a steam-engine, and to other purposes, consists in a certain arrangement or combination of mechanism,

whereby, on rotary motion being communicated to a shaft from the engine, or other motor, said shaft, or spur-wheel carried by`it, is made vto set in rotary motion, by a pinion in gear with the spur-wheel, a secondary shaft, hung on or to turn in a balanced or weighted lever, which secondary shaft carries arms provided with vanes, so that, on the speed of the motor being increased or diminished beyond the velocityt is required to move, anI increase or diminution of resistance is met with by the 'fan against the air, which ca uses the lever carrying the secondary shaft to rise or fall, and in so doing to regulate, by an arm and other suitable connections, the speed of the n1ctor, as, for instance, by controlling the throttle-valve of an engine; and the 4invention furthermore consists in la combination, with such an arrangement, of a shell or airvessel,`connected with the lever carrying the secondary shaft, and open at its lower end, so that on immersion. of the openg end of the shell in a vessel containing water or bther fluid, said shell, by its expulsion of air from or within it, asV it rises and falls, will 'serve to correct the too great sensitiveness of the governor or regulator.

Referring to the accompanying drawing, A represents a column carrying a table, B, on which are erected journal-boxes C '0, thatserve, directly or indirectly, tof carry a horizontal shaft, I), which is `caused to revolve7 as indicated by the arrow zu, by or through a pulley, E, from the engine or other motor. This shaft I) carries a spur-wheel, F, which gears with a pinion, Gr, fast on a shaft, H, which has its bearings in a lever, I, that is free to vibrate or turn on the shaft D, and that,. by anextension-of its collar,

or bearing through the one journal-box C, carries an arm or lever, J, from which connection may be made tc'regnlate the throttle-valve of the engine or other device controlling the speed of the-motor.

- `The lever I has adjustable on it,` at its pinion-end, a weight, K, and if desired, a similar weight may be applied to the opposite end of said lever, while the pinion-shaft H, which runs in said lever, eariies arms L, having any desired number of vanes a. Connected with the opposite end cf the lever I, to which is the pinion G, is a shell, M, of an inverted-bucket form, being open below and closed above, or having its communication above, with theoutside air, established and regulated by a cock, b. This air-shell or vessel is partially immersedin avessel, N, containing water or otherl suitable fluid.

From this description it will be seen that the ,lever I, being balanced or set by the weight or weights on the end or ends of it, to occupy a fixed or certain position,

when the wheel F is rotated in direction of the airow x, at a velocity as acquiredl om the engine or motor, when running at its regular or desired speed, no motion of the lever J takes p lace to move the throttle-valve or other device, so as to alter the velocity of the en gine or motor, but, supposing the latter to be .unduly quickened, then the increased resistance, as encountered bythe vanes a of the arms L against the air, causes such a pressure or resistance to be thrown upon the pinion G, in its `gear with the wheel E, as that the pinion-end of the lever I is raised, and the lever -J moved to act, say, upon theV throttle-valve of the engine in such manner as to check the speed of the latter. l Ou the other hand, a lowering ofthe speed of the motor, causes, by the diminished resist ance encountered by the vanes c, of the arms L, the pinion-end of the lever I to fall, and so tov open the throttle-'valve to quicken and adjust the velocity of the engine. The air-bucket or shell M, as -it is raised or lowered by the action of the lever I within the uid in the vessel N, serves to operate as a check against too great sensitiveness on partof the regulator, and by the adjustment ofthe tap er cock b, so as to admit of av quicker or slower expulsion of air from the shell M, or more rapid or retarded suctionthrough it, the action of the shell M, as a regulator of sensitiveness, may be adjusted to the greatest nicety.

What is here claimed, and desired to beA secured by Letters Patent, is

l. The arrangement of the spun-wheel F, pinion G, weighted lever I, and vane-arms L, substantially as shown and described.

2. The inverted bucket or air-shell M, having an air-cock,b, 'and vessel N, in combination with the spur-wheel F, pinion G, weighted lever I, and vanearms L, substantially as herein set forth.

In witness `whereof, I have hereunto set my hand, this 25th day of July, 1868.

'y JOSEPH THEODOR LOSSEN.
