WINDIVHLL CUT-OFF.
SPECIFICATION forming part of Letters Patent No. 692,392, dated February 4, 1902.
Application filed August 3, 1901. Serial No. 70,796. (No model.)
To all whom it may concern:
Be it known that we,RUFUs WHITE \VALDO and AUSTIN GRANT BONHAM, citizens of the United States, residing at King City, in the county of Gentry and State of Missouri, have in its operation, and composed of a minimum number of parts.
A further object of our invention is to provide a device which will easily and automatically throw the mill out of gear with the pump when the water in the tank has reached a desired height, thus insuring a fixed quantity of water always in the water-tank.
With these objects in view our invention consists in the novel arrangement of the operating mechanism and also in certain other novelfeatures of construction and in combination of parts, which will be hereinafter fully described and afterward specifically pointed out in the appended claims.
Referring to the accompanying drawings, Figure 1 is a perspective view of our invention in an operative position. Fi g. 2 is an elevation of the pump-rod, showing manner of adjusting lugs thereon.
Like numerals of reference indicate the same parts throughout both figures, in which- 1 is the base, and 2 the upright guide provided with the flanges 3, thus forming the groove 4, wherein the dog-rod 5 is adapted to operate vertically. Secured at some distance in front of the upright guide 2 is an upright standard 6, to which is pivoted the dog-lever 7 of the second degree. Pivoted to said doglever 7 is a dog 8, formed, preferably, as shown in Fig. 1 and constructed so that it will always tend to engage the dog-rod 5. Pivoted to the upright guide 2 is a dog-lever 9 of the first degree, and a dog 10, identical with dog 8, is pivoted to the shorter arm thereof, said dog also having a normal tendency to engage the dog-rod 5. Secured to said dogs 8 and 10 are wires 11, which connect with the floatwire 12, said float-wire 12 being fastened to a lever 13, to which is hung the float Within the tank 15.
16 indicates the pump-rod, which is adapted to reciprocate between the dog-levers 8 and 10. On the sides of said pump-rod we provide lugs 17, which engage the dog-levers 7 and 9. It will be noticed by referring to Fig. 2 that we can adjust said lugs at different points, so as to increase or diminish the movement of said dog-levers, and consequently control the throw of the dogs themselves. We do not, however, wish to limit ourselves to this manner of adjusting thelugs, as there are a number of ways for sliding said lugs to different points along said dog-levers.
18 indicates a spiral spring connected to the top of the dog-rod 5, and 19 is the cut-off wire connected to said spring.
2O indicatesa similar spring of less tension connected to the bottom of said dog-rod, the object of which will be hereinafter fully de scribed.
Having thus specifically set forth the'several parts of our invention, its operation is as follows: The cut-01f being in position, as shown in Fig. 1, let us suppose that the water in the tank is low. The float will follow the level of the water, and thus pull the float- Wire and dogs out of engagement with the dog-rod. The spring at the top of said dogrod immediately raises the same, the lower spring merely acting as a cushion when the dog-rod completes its upward movement and offsetting the jolt which would otherwise occur. The cut-01f wire goes up with said dogrod and throws the mill in gear with the pump in any approved manner. The pump starts to Work immediately and commences to fill the tank. When the water rises insaid tank to a certain predetermined distance, the float,which follows the level of the water, rises also and causes a slack in the float-wire. This allows the dogs to engage the dog-rod, and as the dogs are operated by the pump-rod they pull the dog-rod down notch by notch in the following manner: One of the dog-levers is of the second degree-that is to say, the lever is fulcrumed at its end and the resistance, which is the dog-rod, is between said fulcrum and the power, which is the pump-rod. The other doglever is of the first degreethat is to say, the fulcrum is between the resistance, which is the dog-rod, and the power, which is the pump-rod. It is therefore evident that when both dog-levers are raised the dogs themselves are moved in opposite directions, one up and one down, which is also the case when both dog-levers are lowered. Consequently as the pump-rod reciprocates up and down the dogs are alternately raised and lowered and alternately engage the ratchet-teeth in the dog-rod and force said rod down tooth by tooth, which throws the mill out of gear with the pump, thus preventing any more water being pumped into the tank-until the same is used, when the dogs are again pulled out of engagement with the do -rodand the mill again thrown in gear with the pump.
In order to secure a fine adjustment of the above-described mechanism, we have provided the lugs, which engage the dog-levers adjustably on said levers, so as to regulate the upward and downward throw of the dogs, which controls the rapidity with which the dog-rod is lowered.
Having thus described the operation of our invention, we do not wish to be understoodas limiting ourselves to the exact construction as herein set forth, as various slight changes might be made therein which would fall within the limit and scope of our invention, and we consider ourselves clearly entitled to all such changes in form and construction. V
What we claim, however, as our invention, and desire to secure by Letters Patent of the United States, is Y 1. In a windmillcut-off, the combination of a ratchet dog-rod, a spiral spring at the top thereof, a cut-off wire secured thereto, a spiral spring at the bottom of said dog-rod, a doglever of the first degree secured to one side of said dog-rod, and fulcruined in the guide of said dog-rod, a dog-lever of the second degree, secured on the opposite side of said dog- .rod, and fulcrumed to an upright standard located in front of and to one side of said dogrod, dogs secured to said dog-lever, and adapted to engage the teeth in said dog-rod, conmeeting-wires secured to said dogs, a float connected to a wire which connects with said connecting-wires and adapted to disengage said dogs from the dog-rod, a pump-rod having lugs thereon adapted to engage said doglevers, said lugs being adjustable so as to limit the throw of said dogs, substantially as and for the purpose set forth.
2. In a windmill cut-01f, the combination of a pump-rod, lugs adjustably secured thereto, a ratchet dog-rod secured ina guide, dog-levers of the first and second degrees, fulcrumed on either side of said dog-rod, dogs secured to said dog-levers, springs secured to the top and bottom of said dog-rod, a float, means for connecting said float with said dogs, substantially as described.
3. In a windmill cut-off, the combination of a pump-rod, a ratchet dog-rod secured in a guide, dog-levers of the first and second degrees fulcru med on either side of said dog-rod, dogs secured to said dog-levers,a float adapted to disengage said dogs from said dog-rod, the whole arranged so that said dogs operate in opposite directions when the pump is reciprocated, substantially as described.
In testimony whereof we affix our signatures in presence of two witnesses.
