SPECIFICATION forming part of Letters Patent No. 716,292, dated December 16, 1902.

Application filed March 10, 1902. Serial M91423. on. model.)

have invented certain new and useful Im provements in Windmill-Oiling Apparatus,

of which the followingis a specification.

The objects of my invention are to provide a device capable of being applied in the way of an attachment to any ordinary windmill,

to which it is firmly secured in such a manner that it will not in any way interfere with the usual functions of the windmill proper, and when applied to the windmill the operator may, by manipulating a pump attached to the windmill-base,-supply lubricating-oil to all of the operative parts of the windmill at the top of the tower, and when a sufficient amount of oil has been supplied to the various bearings the oil in the supply-pipe will all return to the pump at the base of the Windmill, so that there will be no leakage or waste of the oil and so that no oil will be left in the oil-supply pipes to harden under various atmospheric conditions or clog the supply-pipes.

My invention consists in certain details in the construction, arrangement, and combination with a windmill of the various parts. of the attachment whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 shows in perspective the upper and lower portions of the windmill-tower with my invention applied thereto as required in practical use. Fig. 2 shows an enlarged detail sectional View through a portion of the annular collar and connected parts at the top of the windmill-tower.

Referring to the accompanying drawings, I have used the reference-numeral 10 to indicate a corner-post of the windmill-tower; 11, the platformat the base thereof. At the top of the windmill-tower is a metal cap 12, such as is usually provided to cover the tops of the corner-post of awindmill-tower. Mounted on this cap 12 is an annular metal collar 13, made of two parts, which divides the collar into two semicircular pieces, which pieces are connected by the bolts 14. The top surface of this collar is flat, and a series of bolts 15 are passed through the collar to engage the cap 12, so that the collar is firmly fixed thereby to said cap, and the collar stands normally in a horizontal position. The cap of the windmill-tower is usually smallest at its top, and hence a collar such as 13 will fit upon caps such as 12 of the various sizes because it does not matter how near the top the collar rests.

Bolted to the inner periphery of the collar 13 is a series of fiat metal guides 16, their upper ends projecting some distance above the collar 13, each end being pointed at right angles and slotted to admit a sliding bar 17. In the top of each of the bars 17 is a bolt 18, and a roller 19 is rotatably mounted on said bolt. At the bottom of each of the bars 17 is a wire 20. gle wire 21, which is attached to the lever 22, fulcrumed to the base of the windmill-tower, and the hook 23 pivoted to said base is designed to engage the lever 22 to lock it atits downward limit of movement. Obviously when the lever 22 is pressed downwardly all of the rollers 19 will be forced downwardly at the same time.

The reference-numeral 24 indicates a twopart annular metal ring, the parts of which are connected by means of the bolts 25, and said ring is substantially the same size as the collar 13. On its under surface is an annular groove 26, and the ring 24 rests upon a flexible cushion or washer 27, which. washer or cushion rests upon the top of the collar 13. The said guides 16 engage the inner surface of the ring 24, and the rollers 19' engage itstop surface. Hence all movements of the ring 24, except rotatorymovements, are prevented. Fixed to the ring 24 is a pipe 28, having communication with the annular chamber 26 and projecting upwardly and provided with a number of oil feeding pipes 29. Thesaid pipes 29 may be connected with the various oil-holes of a windmill-wheel and turntable. In this connection it is to be remembered that because the various makes of windmills are provided with oil-holes at different points hence the pipes 29 are preferably flexible, so that they can be connected direct These wires connect with a sin with the various oil-holes of the Ordinary windmills, and the feeding-pipe 28 will obviously rotate with the wind-wheel upon the turn-table thereof, the rollers 19 providing this movement.

Fixed to a portion of the windmill-tower near its base is a pump 30, having a handle 31 fulcrumed to the support 32,and connected with the pump-rod'33, fixed to the bottom of the pump, is a pipe 34, which extends through the collar 13 and through the washer 27 to discharge its contents into the annular chamber 26.

g In practical use the device is attached to a windmill as follows: The parts 13 and 24: are divided and placed on opposite sides of the windmill-tower and then the parts of each are bolted together, with the washer 27 between them. Then the collar 13 is bolted to the top of the windmill-tower, as described, and the supply-pipe 34 is connected with the pump 30, and the supply-pipe 28 is secured to a portion of the windmill-frame that turns in a horizontal plane, so as to move in unison therewith, and the branch pipes 29 are then permanently connected with the oil-holes of the windwill, and obviously the collar 13 is permanently fixed to the tower, and the ring 24 will freely rotate with the turn-table of the wind-wheel. Assuming that itis desired to oil the working parts of the windmill and turn table, the operator first presses the lever 22 downwardly and secures it in position. This will press the edges of the ring 24 firmly into the Washer 27 and prevent oil from leaking through between the ring and the collar. Then the operator manipulates the pump 30, which is filled with oil, thereby forcing the oil through the pipe 34 into the annular chamber 26 and from the annular chamber 26 through the supply-pipes 28 and 29 to the oil-holes. When a sufficient quantity of oil has been supplied to the work ing parts, the pump 30 is stopped and obviously all of the oil in the supply-pipes will return into the pump. After the oil returns the lever 22 is released, and the windmill is again ready for use and there is no oil remaining in quantities at the top of the windmill-tower, where it will be liable to leak or be affected by atmospheric conditions.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is-

1. Animproved windmill-oilingapparatus,

comprising in combination a collar to be pei manently fixed to the top of the windmilltower, a ring having an annular chamber therein rotatably mounted on top of the collar, a pipe leading from the annular chamber to the ring to discharge into the oil-holes of the windmill, a pump at the bottom of the windmill-tower and a pipe leading from the pump to the annular chamber of the said ring, for the purposes stated.

2.

3. An improved windmill-oiling apparatus, comprising in combination a two-part annular collar the parts of which may be bolted together and firmly fixed to the top of the windmill-tower, a series of guides'fixed to the inner surface of the annular collar and projecting above it, slots in said guides, rollers mounted in the tops of said slots to project over the annular collar, means for simultaneously directing the slots downwardly and holding them in position, a washer on top of the annular collar, a two-part annular ring and means of securing the parts together, said ring having an annular chamber in its inner surface and also having a flat top surface upon which the said rollers bear, a supply-pipe fixed to the annular ring and communicating with the annular chamber thereof and designed to communicate with the'oilholes of the windmill, a pump to be fixed to the base of the windmill-tower and the supply-pipe passed through the annular collar to discharge into the annular chamber, substantially as and for the purposes stated.
