IMPROVEMENTlN GOVERNORS.

Specification forming part of Letters Patent No. 219,95L-dated September 23, 1879 application filed September 3, 1879.

To all whom it may concern:

Be it known that I, MATHIAS L. J AOQUEMIN, of Council Bluffs, in the county of Pottawatta: mic, and in the State of Iowa, have invented certain new and useful Improvements in Grovernors; and dohereby 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 engines, &c., as will be hereinafter more fully set forth.

In the annexed drawings, Figure 1 is a side elevation of my governor, showing the same connected to a valve-regulating mechanism. Fig. 2 is a similar view of the governor alone. Figs. 3, 4, and 5 are detailed views of the parts thereof. Fig. 6 shows a modification of a part of the governor.

A represents the foot or stand of the governor, the upper portion of which is slotted, and has a suitable plate or bed, B, which supports the hollow column O of the governor. Through this hollow column is passed a hollow tube, G, having a beveled cog-wheel, S, attached to its lower end immediately below the bed B.

On the upper end of the hollow tube G is attached a cap with frame H.

Between suitable ears on opposite sides of this frame H. are pivoted the governor-arms I 1. Each of these arms has an inward projection or extension, b projecting at an angle through a slot into the frame, and on the end of said projection are side pins, 6 which work between two slotted disks or collars, f f", on avertical rod, h which passes through the interior hollow tube G.

The governor-arms I are, by rods J, connected with a sliding sleeve or collar, K, on the governor-column C, and this collar is, by a suitable coupling, connected with a rod, L, the other end of which is connected to an arm projecting from .the mechanism for regulating the stroke of the cut-off valve.

M is the governor-shaft, having its'bearings in suitable,hangers from the bed-plate B, and receiving its motion from the shaft on which the valve regulating mechanism is placed by means of pulleys and belt or otherwise, as may be deemed most convenient.

On the shaft M is secured a beveled gearwheel, S, which meshes with the gear-wheel S on the lower end of the hollow tube G, and thus communicates rotary motion to the governor-arms.

The governor is thus connected directly with the device for regulating the stroke of the cutoff valve, which is, therefore, done automatically with the greatest precision and regularity.

On the shaft M is placed a loose bevel-gear wheel, S which meshes with the wheel S opposite to the wheel S said wheel S being formed with a clutch-hub, 2'

- On the shaft M is further secured a clutchcollar, 70 and a loose sleeve, N, having exterior worm-threads m The vertical rod h of the governor is, at its lower end by a bar, P, connected to the long arm of an elbow-lever, O, which is pivoted at its angle in the slotted portioh of the governorstand A The short or vertical arm of the lever O has at its end two side plates, n n which project on both sides and form guides for the ends of a wire spring, F, the center of which is coiled around the pivot r of the elbow-lever.

On the pivot r is further pivoted an arm or lever, B, the upper end of which is forked and straddles a double clutch, V, placed on the shaft M between the two clutches i and k From the arm R extends a pin, 5 upon which is placed a bar, W. This bar is formed with two arms, t2 and v The arm 15 is straight and passes through a suitable guide, Y, while the arm c is curved and formed with two projections, 50 and y, to be operatedby a lug, e, on the bar P, which forms the connection between the vertical rod h of the governor and the elbow-lever O.

In suitablebearin gs attachedto the governorbed B is placed a sleeve,-V, having interior screw-threads, and throughthis sleeveis passed a screw-rod, A, which may \be connected at one end directly to the arm or lever of the throttle-valve, or by means of an intermediate coupling, according to the location of the governor. On the sleeve V is a worm-gear, W, which engages with the worm m on the loose sleeve N on the shaft M. The loose sleeve N has two projecting arms, to, which fit in notches on afiange, 3 of the double clutch V, so as to be turned at all times therewith.

The normal position of the double clutch V is in gear with the clutch-collar k so that the said clutch and the sleeve N will rotate in the same direction as the shaft M. As the engine then is started, the sleeve N rotates with the shaft and turns the worm-gear W and sleeve V, moving the rod A in one direction to open the throttle-valve. As the speed of the engine increases and the governor-arms I spread outward by the centrifugal force, the lug 2011 the bar P arrives at the side of the lug .r on the arm n of the bar W.

The movement of the vertical rod h of the governor, through the medium of the bar P, turns the elbow-lever 0, so that if the speed of the engine still increases the lug z of said bar P will pass down below the lug .r, the spring 1) will turn the arm R, and thereby move the clutch V snfliciently far to disengage it from the clutch 1: The lug being now against the lug 3/ on the arm 1' of the bar W, the double clutch V remains between the clutches i and 70*. and with the worm-sleeve N stationary on the shaft and during this time there is no change in the position of the throttle-valve. Should, however, the speed of the engine still increase, the lug 2 on the bar I? will pass down below the lug y, and the spring 19 throws the double clutch entirely over and in gear with the clutch P. This clutch forming part of the wheel S which revolves in the opposite direction to the shaft M, it will readily be seen that the wormsleeve N receives a rotary motion in the opposite direction, to that of its former movement, and hence the rod A will be moved in the opposite direction so as to commence operating the throttle-valve and shut off the power.

As the speed of the engine decreases the bar P ascends again, and its lug z operates on the opposite sides of the lugs y w in a reverse manner, so as to first place the clutch in the intermediate position, and finally back in contact or gear with the clutch k By this device I establish an isochronous circle or determined zone of movement of the governor-balls, where no change is caused in the throttle-valve but as soon as the governor-arms pass either above or below this circle the valve commences to change.

In some cases a friction-clutch may be used on the governor-shaft M. My governor may be used with any kind of engine; also for water-wheels, 8:0.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a governor, the combination of a hollow column, 0, hollow tube G, with bevelgear wheel S, rod h governor-arms I, with projections 11 having pins 6 collars f braces J, and sleeve K, all substantially as and for the purposes herein set forth.

2. In a governor, a mechanism whereby an isochronous circle is established, and no change in the valve made while the governor-arms rotate in such circle, substantially as herein set forth.

3. The combination, in a governor, of the shaft M, loose wheel S having clutch i, the stationary clutch is, loose worm-sleeve N, with arms 10 and the movable double clutch V, with notched flange g substantiallyas and tor the purposes herein set forth.

4. In combination with the double movable clutch V, the forked arm It, elbow-lever O, double-acting spring pflbar P, with lug z, and the bar W, with arm v having lugs w 3 substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing 1 have hereunto set my hand this 1st day of September, 1879.

M.' L. JAGQUEMIN.
