ATTACHMENT FOR WINDMILLS.
SPECIFICATION forming part of Letters Patent No. 337,421, dated March 9, 1886. Application filed November 13,1885. Serial No. 182,730. (No model) To all whom it may concern.-
Be it known that I, GEORGE WEsLEY BI-IL- LER, a citizen of the United States, residing at Glarinda, in the county of Page and State of Iowa,haveinvented a new and useful Improvement in Attachments for WVindmills, of which the following is a specification, reference being had to the accompanying drawing.
This invention relates to attachments for windmills for throwing the wheel into and out of operation, and its object is to provide mechanism possessing superior advantages in simplicity, convenience, and general effic1ency,by which the wheel will be automatically thrown into and out of operation by a float in a tank, and the water in the latter will be automatlcally kept at the same level.
This invention is an improvement on that for which Letters Patent of the United States were granted to me January 15, 1884, N 0. 292,030.
The accompanying draw ng is aperspective view of a machine embodying my invention.
A represents a portion of the tower or framework of a windmill,on the upper end of which is secured a wind-wheel,which may be of any preferred construction, but which s not here shown, as it forms no part of this invention. The wheel will be provided with mechanism by means of which it may be thrown out of the wind, said mechanism being controlled by a cord, B. To the lower end of this COId IS attached a bar, 0, which is provided on its outer edge with ratchet-teeth,and which slides on a stanchion, D, in the tower, and is kept in place on said stanchion by means of guidea s E.
W 11 represents the pump or plunger rod which is connected with the crank-wheel of the windmill, and which reciprocates vertically when the windmill is rotated in the usual well-known Wag rock-lever, G, is fulcrumed to the lower end of the stanchion D, and the outer end of said lever is connected or pivoted to the pumprod F, as shown. To the inner end of this lever is pivoted a pawl, H, whlch s maintained in a substantially vertical position normally, and has outwardly-extending parallel arms h, which extend on opposite sides of the ratchetbar 0 and the stanchion D, so as to guide the lower end of the said ratchet-bar, and on the outer ends of these arms are secured weights h. In between the guideways E is pivoted a downwardly-extending detent, I, which is provided with a right-angled weighted arm, K.
L represents a lever, which is pivoted at its upper end to the outer end of the guideway E, and is connected to the free ends of the detent and the pawl by means of cords M.
N'represents a sheave that is journaled to a bracket projecting from the stanchion D, and over which passes a cord, 0. A weight,l?, is attached to one end of this cord, and the cord is also connected to the lower free end of the lever L, and from thence passes through a bracket-eye. R, the outer lower end of the cord being attached to a float, S, in a tank, T. This tank is kept supplied with water from a pump or other water-elevator operated by the windmill.
The operation of myinvention is as follows: When the water is at a certain predetermined level in the tank,the float draws upon the cord 0 and moves the lever L outwardly, which keeps the free ends of the detent and the pawl out of engagement with the ratchet-teeth of the bar 0. The pawl H,being connected with the reciprocating plunger-rod by the lever G, 4
moves continually up and down while the wind-wheel is in operation. When the water rises in the tank above the required lever,the float is raised, which slackens on the cord 0 and causes the weight 1? to draw the lever L toward the pump-rod, and permits the detent and the pawl to engage with the ratchet-bar. The continuous reciprocating movement of the pawl on the teeth of the ratchet-bar draws the said bar downwardly, as will be readily understood, and the detent, by engaging with said teeth,h0lds the ratchet-bar in the lowered position. As the bar is drawn downward it exerts a pull on the cord B and causes the windwheel to be thrown out of the wind, and thereby causes the pump to cease to operate, thus preventing the water from overflowing the tank and being wasted.
Having described my invention,I claim-- 1. The combination of the movable ratchet bar, the reciprocating plunger-rod, the detent for engaging with the ratchet-bar, the pawl connected to the plunger-rod and reciprocated thereby, and the lever L,connected to the free ends of the detent and the pawl to keep the latter normally out of engagment with the ratchet-bar, substantially as described.
2. The combination of the ratchet-bar, the detent for engaging therewith, the reciprocating plunger-rod,the pawl connected therewith and reciprocated thereby, the lever L, connected with the free ends of the pawl and the detent, and the float connected to said lever, whereby the pawl and detent will engage with the ratchet-bar to move the latter when the float rises, and will release the ratchet-bar when the float descends, substantially as described.
3. The combination of the movable ratchet- L, connected to the pawl and detent, and the float connected to the said lever L, for the purpose set forth, substantially as described.
4. The cord or chain B, connecting with the wind-wheel, in combination with the pitman or plunger F, the movable ratchet-bar G on the end of cord B,the pawl H,engaging there'- with,the lever G,connecting the pawl with the plunger, and a float connecting with the pawl, as set forth.
5. The chain or cord B,connecting with the wind-wheel, in combination with the pitman or plunger F, the movable ratchet-bar O on the end of the cord, the pawl H,to engage the ratchet-bar, the float to keep the pawl in engagement when it ascends and force the pawl out of engagement when thefloat descends,the said plunger or pitman connecting with the pawl, for the purpose set forth.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
GEORGE WVESLEY MILLER.
