HENRY HOWE, OF COUNCIL BLUFFS, IOWA.

IMPROVEMENT IN GOVERNORS.

Specification forming part of Letters Patent No. l 76,957, dated May 2, 1876 application filed February 21, 1876.

' To all whom it may concern.-

Be it known that I, HENRY HOWE, of Council Bluffs, in the county of Pottawatta. mie, and in the Stateof Iowa, have invented certain new and useful Improvements in Grovernors; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a governor for steam-engines, water-power, 850., as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains'tomake and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in whieh- .B, placed in a frame, 0, and actuated by means of a screw-shaft, b, said shaft beingv placed in suitable bearings on the frameO, and provided on its inner end with a vertical friction-wheel, D. d is the shaft, with pulley 0, through which motion is communicated to the governor, said shaft being, by miter or beveled gears ff, connected with the upright shaft E of the governor.

The upper end of the shaft E is hollow, and

has a rod, h, passing down into it. This rod.

has on its upper end a cap or knob, G, into holes in which the inner ends of the governor-arms H H are inserted, said governor-arms being pivoted to armsk, projecting from the upper end of the shaft E.

()n the shaft E is placed a tube, I, with two horizontal disks, J J, and this tube is, by a pin, 6, connected with the lower end of the rod h, said pin passing through a vertical slot in the shaft E. The position of the parts will be such that the disk J is below and the disk J above the friction-wheel D.

'tion is obtained under all circumstances.

When the governor revolves slowly the I slide in the proper direction for opening the valve by means of the lever A. When the governor revolves faster, and the arms H rise, the tube 1 is thereby depressed, causing thedisk J to come in contact with the friction-wheel, and rotate the screw-shaft b in the opposite direction, and thereby closing the valve. As the speed then decreases, the movement is reversed again. a

The head G will, in a working machine, be connected to the rod h by screw-threads, so that the tube, withits disks, may be raised and lowered at will, to increase or decrease the motion of the governor-arms, as the case may require.

By this governor a perfectly-regular mi)- t will keep exactly the same motion of the engine, whether the steam is high or low, only so that there is steam enough to give it the desired speed with the valve wide open, or whether there is much had to pull, or none at all.

In a working machine the friction-wheel D will be so close to both the disks J J that the least variation of speed will at once make the required change.

. The frame 0,111 a full-sized working machine, will be in a slide, with a spiral spring on top, so that in case the governor-belt should break or run ofi' the weight of the balls will force said frame upward, and thereby disconnect the slide from the crooked lever that -works'the valve-stem, so that the motion will by the same in such an event as if nothing had happened.

This governor, with a slight alteration, can be used as a governor for water-power as well as for steam.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The valve-stem a, sliding frame 13, both connected bv the bent lever A, the screwshaft b, friction-wheel D, and disks J J, all substantially as and for the purposes herein set forth.

2. The combination of the rotating governo'r-shaft E, with weighted arms H H, havhave hereunto set my hand this 25th day of ing their ends connected to the adjustable January, 1876. head G rod h, and tube I, with disks J J, friction wheel D, screw-shaft 1), frame B, lever HENRY HOWE A, and valve-rod a, substantially as and. for Witnesses: the purposes herein set forth. J. D. EDMUNDSON,

In testimony that I claim the foregoing I N. C. PERKINS.
