LUBRICATOR FOR WINDM ILLS.-

SPECIFICATION forming part of Letters Patent No. 652,785,dated Ju1y 3, 1900. Application filed October 14, 1899- Serial No. 733 ,621. (N 0 model.) 7

To all whom it may concern:

Be it known that I, HORACE M.KEITH,a citizen of the United States, residing at Commerce, in the county of Oakland and State of Michigan, have invented certain new and usefullmprovements in Lubricators for Windmills, of which the following is a specification.

Towers of windmills are constructed'for climbing as a means for reaching the bear ings of the working parts to oil them, and my improvements are directed to novel means whereby this may be effected from the ground by a single rope controlling means for lubri eating all the bearings, and the particular matters of my improvement will be pointed.

out in the claims concluding this specification, in connection with the accompanying drawings, in Which a Figure 1 is a side elevation of thereto. Fig. 2 is a vertical section of an'oiltank surm ounting the tower, having conduct ing-tubes and a Vertically-slidable and rock- I able bar of cups or cells in the position it 00- cupies within the tank to empty the cups.

' showing the cup-bar in the position it occupies in being raised to deliver the oil into the conducting-tubes through the tank-openings, and Fig. 7 shows the oil-tube connection with the crank-pin. v

In the'drawings I have shown so much of the head of a windmill as revolves about and upon the wear-plate of the tower; but my oiling device can be applied to any windmill.

The pump-rod 1 is connected by a pitmanrod 2 to the crank-shaft 3 of the w ndmill, and the bearings of these parts are sufficient to illustrate the application of my cup-bar oilfeeder.

An oil-tank 4; is supported and braced upon the head above the bearings of the working parts. and may be of any suitable construction, preferably of rectangular form. On one of its outer Vertical sides the tank has a numthe tower of a windmill having my improved oiler applied Fig. 6.

It may hold one or more gallons of oil tubes is a horizontal bar 8, containing cups and arranged to slide vertically in guideways 9 and to be rocked on ,the inner wall of the tank. This bar is preferably of wood, be-

cause of. its cheapness and lightness-and of square cross-section, so that it has a flat side slidable upon the wall of the tank. .At its ends 10 itis rounded at one corner, Fig. 4, of

the square, which maybecalled the rear lower angle, so as to permit itto'be rocked a quarter of a circle in itsguideways. The

cups or cells are formed by transverse bores 11, preferably obliquely to the square, and

have short spouts 12, so that when the bar is depressed and immersed in the oil'the spouts stand up and the cells or cups are filled, as in The inclination at which the spouts are set will cause their ends to rest against the tank-wall to prevent the bar from rock ing, so that the bar must rise with the spouts so standing to retain theloil. c. When, however, the feed-bar is caused to slide up in its guideways to bring the scoop-shaped endsof the spouts in the tankwall openings 6, itjis caused to rock or turn toward the wall, and thereby project the spouts through the said wall-openings, so as to pour the contents of the cups or cells into the conducting-tubes.

It is to allow the cup-bar to so rock that its ends 'are rounded; but the function of these rounded ends is only rendered possible when the spout ends are moved into the wallopenings and the force to raise the bar is exerted at a point thereon to cause it'to rock. This rocking movement is prevented as the cup-bar is being pulled up, and the cup-spouts arecaused to'retain their upright position by reason of the flat side of the bar and the ends of the spouts being held in contact with the inner wall of the tank. Referring, toliig.- 3, it is seen how the cup-bar retainsit's upright position on its Way up by the lifting action of the rope, as seenin Fig. 6, which constantly tends to cause the bar to turn toward the wall to cause its spouts to dip outward. As the spouts on their way up reach their respective openings their ends have no support to resist the turning of the bar and itis caused to rock, and the spouts are thereby turned down into the openings, as seen in Fig. 2. In Figs. 3 andt both ends of the cup-bar are shown as rounded to allow it to rock while being held in position by the guideways. In the construct-ion shown the normal position of the cupbar is at its highest when delivering the oil, and it is operated by a vertical rod 13, jointed to and rising mediately of the bar and passing through an opening in the top of the tank,

and which rod is connected to a rod-spring 14, secured to and rising from the tank, so as to constantly pull the cup-bar upward. To fill the cups or cells, a cord or chain 15, connected to the upper end of the rod or spring and extending to the ground, is pulled, which pulls or forces down the cup-bar to immerse its cups, and releasing the pull of the rope the cupbar is automatically lifted and automatically rocked orturned to place its spouts into and through the wall-openings to pour out the oil. It is the lifting function of the spring, the provision of wall-openings, and the capacity of the cup-bar to rock that give the automatic delivery of the oil from the tank to the bearings, and for this purpose the spring may be of any suitable kind and arrangement. Any other lifting means may be employed, and the normal position of the cup-bar may be at the limit of its descent, as it is evident that in these particulars my invention is not limited to the construction shown.

It is important to note that the cup-spouts when projecting into the wall-openings i11- cline downward and so are held by the action of the spring and are rocked back to the position in which they are caused to slide down against the tank-walls when the ground-rope is pulled. The tank-wall openings are arranged in horizontal line and the pouringthat when the spouts enter said wall-openings they are held in pouring positions. It is important also to note that the lifting-rod is hinged or jointed to that side of the cup-bar at 15, Fig. 6, opposite to its wall-bearing side, so that it is the lifting action of the rod that causes the bar to be rocked or turned to project its spouts into the wall-openings and the pulling down of the rod that causes the bar to be rocked back to withdraw its spouts from the openings. The jointing of the rod to the cup-bar at that side away from the spouts gives an eccentric action upon the bar to cause it to turn, while the rounding of one of the angles of the bar at its ends allows it to turn only a quarter of a circle back and forth.

In Fig. 7 is seen a funnel on the crank-connecting pitman-rod to receive the oil from the conducting-tube 5 during the vibration of the said rod.
