Description: |
| Abstract:
This invention relates more particularly to means for governing the speed of explosive engines by stopping the ignition mechanism and holding the exhaust valve open.
The primary object is to provide novel means of an exceedingly simple and effective nature, whereby the valve or ignition actuating member is locked in an inactive or inoperative position when the speed of the engine reaches a predetermined limit, and another important object is to provide means, whereby this limit of speed may be readily varied without the necessity of stop ing the engine or otherwise interfering with its operation.
Claims:
1. In governing mechanism of the class described, the combination with a reciprocatory actuating member having a slot, of a supporting element disposed transversely of the actuating member and passing through the slot, a reciprocatory latch slidably mounted on the supporting member and movable into and out of co-action with the actuating member, and a centrifugal member for sliding the latch upon the support.
2. In governing mechanism of the class described, the combination with a movable actuating member, of means for operating the same, a governor shaft, a governor driven thereby, and a non-rotatable latch mounted on the shaft and slidable thereon into and out of co-action with the actuating member, said latch being moved by the governor.
3. In governing mechanism of the class described, the combination with a movable actuating member, of means for operating the same, a governor shaft, a governor mounted thereon, and a reciprocatory latch separate from said operating means, slidably mounted on the shaft and movable into and out of co-action with the actuating member to hold the same in inoperative position with respect to the operating means, said latch being operated y the governor.
4. In governing mechanism of the class described, the combination with a movable actuating member, of means for operating the same, a shaft, centrifugal arms pivotally connected to and rotating with the shaft, and a latch comprising a sleeve slidably mounted on the shaft and operated by the arms, said sleeve having a tooth that is movable into co-action with the actuating member to hold the same inactive.
5. In governing mechanism of the class described, the combination with a reciprocatory actuating member having a slot and a notch, of a shaft extending through the slot, an outer bearing for the shaft, a collar secured to the shaft and journaled in the bearing, weighted arms pivoted to the collar, a sleeve slidably mounted on the shaft, said sleeve being actuated by the arms and having a tooth movable into and out of the notch of the actuating member, and means for resisting the swinging movements of the arms.
6. In governing mechanism of the class de scribed, the combination with a support including a casing plate, of a bracket secured to the casing plate, a reciprocatory actuating member disposed in rear of the casing plate, said member having a slot therethrough, and a notch in its outer side, a shaft extending through the slot and through the casing plate, a sleeve slidable on the shaft and having a tooth on its inner end that is movable into and out of the notch of the actuating member, said sleeve slidably en aging the casing plate and being held there y against rotation, a collar fixed to the shaft and journaled in the bracket, and centrifugal arms pivoted to the collar and having portions that engage the sleeve to effect its sliding movement on the shaft.
7. In governing mechanism of the class described, the combination with an engine shaft, of a wheel geared thereto and having a cam, a reciprocatory actuating member engaged and operated by the cam, a governor shaft geared to the wheel, a centrifugal governor mounted on the shaft, and a latch also mounted on the shaft and operated by the governor, said latch being movable into action with the actuating member to maintain the same inactive.
8. In governing mechanism of the character described, the combination with an actuating member, of a reciprocatory latch movable into and out of engagement with the actuating member for holding it against operative movement, a centrifugal governor engaging the latch for moving it in one direction, a lever fulcrumed between its ends and having one end engaged with the latch, and a spring for placing variable tension on the lever, said spring being secured to the other end of said lever and through the lever operating against the centrifugal governor.
9. In governing mechanism of the class described, the combination with i an engine shaft, of a wheel geared thereto and having a cam, a reciprocatory actuating member operated b the cam, a shaft geared to the wheel, a catch slidable on the shaft into co-action with the actuating member to maintain the same in inoperative condition, a centrifugal governor operated by the governor shaft and operating on the latch to move the same into co-action with the member, a lever having an engagement with the latch to move it out of co-action with the member, a spring connected to the lever, a tensioning lever connected to the spring, and a gage plate co-acting with the tensioning lever. and having a scale thereon.
