WILLIAM P. BRETT, OF DECATUR, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 780,932, dated January 24, 1905. Original application filed October 14,1895,Seria11lo. 566,607. Divided and this application filed January 26, 1901. fierial No. 44,945.

To atZZ whom it may concern.-

Be it known that 1, WILLIAM I BRETT, a citi-,

This application is a division of application Serial No. 565,607 for windmills, filed by me October 14, 1895, and relates to means for the automatic'lubrication of the pitman in that class of windmills known as the vertical or upright wheel windmill, in which the pitman operates in either a vertical position or at an incline-from the vertical; and the objects of my improvement are, first,'to reduce friction; second, to dispense with the necessity of frequently climbing the tower to oil the windmill, and, third, to provide means whereby there is no waste of oil by its drip.- ping away from the oil-receptacles as it lubricates the journals or bearings that are ar ranged to operate therein. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a, front view of a windmill with the wheel removed and shows the pitman in an angular position; Fig. 2, a vertical section on line a 2, Fig. 1; and Fig. 3 a front view of the pitman and in vertical sectionshows the oil-receptacle Ql.

Similar characters refer to similar parts throughout the several views.

Referring to Figs. 1 and 2, the casting F constitutes the principal part of the-main frame of the windmill and is provided with the crank oil-reservoir 15. The crank-shaft 14: is carried by this frame, and the crank 14 is so mounted thereon as to revolve partially within the oil-reservoir in such manner as to dip the wrist-pin secured thereto in the oil contained therein when the wheel is in motion. 14: (shown in all three figures) is the pitman and when in a vertical or inclined posion, as shown in Figs. 3 and 1, is provided with the downwardly-projected portion 23 at its upper part, with the wrist-pin or pivotal bearing 23 formed at the lower extremity thereof, the other wrist-pin or pivotal bearing 23 being formed at the lower extremity of the pitman. Thus it is seen that both wrist-pin bearings of the pitman are formed at the lower extremity of downwardly,'

projected portions thereof. For the purpose of giving greater strength to this part of the pitman it is divided and made to pass upward on opposite sides of the upper wrist-pin bearing and uniting above at a-point from which the downwardly projected portion 23 extends. This division of the body part of the pitman forms a large opening through it, which may be made as large as desired to accommodate any size or shape of oil-receptacle into which the downwardly-projected wristpin bearing is adapted to operate. The most essential distinguishing feature of this pitman is its downwardly-projected portions with wristpin or pivotal bearings at the lower extremities thereof, whereby said bearings are adapted to be operatively projected into oil-receptacles during the operation of the wind-mill, and this feature can be made applicable to many modified forms of pitman-body parts and oilreceptacles without departing from the spirit of this invention. One of the wrist-pin bearings of this pitman is eccentrically pivoted to the crank or rotatable member of the windmill 14', and the other is pivoted to a wristpin 2& which is carried by the reciprocating part and is surrounded by a reservoir or oil- 'receptacle 24:, that is mounted to move therewith. 6 is a cross-head or reciprocating part of the windmill and is mounted to slide on

posts

5, and 24 is adownwardly-projected portion of it to which the wrist-pin 24: is secured, and 24' is the oil-receptacle, carried by said reciprocating part and is so mounted as to surround the wrist-pin 24: and'the part to which it is anchored.

The vertical-wheel windmill as they have been made for many years have been divided into two classes, one of which is the windmill designed for operating a double-acting pump in which the center line of the wheel-shaft and the center line of the recip- Y rocating wrist-pin and pump-rod are in approximately the same vertical plane. The other class is the one in which the wheel-shaft is mounted to one side of the vertical plane of the center line of the reciprocating parts, so as to give the pitman connected thereto a more direct pull on the working stroke of the single-acting pump, and by some builders of windmills the wheel is mounted to one side, so that it acts in the capacity of a side Vane as a regulator for the speed of the mill, and this pitman and means for itsautomatic lubrication are as applicable to the one class as the other. In my drawings 1 have shown a directstroke windmill; but it will be readily seen that the mechanism here illustrated and described is as applicable to the geared mill as to the direct-stroke type.

In operation the crank end of the pitman is lubricated by being dipped in the oil in the crank oil-reservoir at each revolution of the crank and the reciprocating end is lubricated by the bearing thereof beingimmersed in the oil in the reservoir that is mounted to move with the reciprocating part of the windmill, and as the motion of these parts of the windmill is very slow there will be no loss of oil by splashing from the receptacles containing it, and as both of the pivotal connections of the pitman operate in or directly above the oil-reservoirs it is readily seen that there can be no loss or waste of oil by its dripping therefrom.

Having thus described my invention and a mode of its operation, what I claim as new, and desire to secure by Letters Patent, is
