To all 1.0710112 it may concern:

-Be it known that we, LINNAEUS C. POND and GEORGE C. WAGNER, both citizens of the United States, residing at Los Angeles, in the county of Los-An eles and State of California, have invente new and useful Improvements in Windmill-Oilers, of which the following is a specification.

In a former patent issued on March 16, 1897, to Linnaeus C. Pond, No. 579,008, is shown a distributer for lubricating the bearings of a windmill, the oil being delivered to the distributer from a reservoir from time to time by suitable valve means which was operated by hand from the ground.

The object ofthe present invention is to provide for automatically delivering oil eriodically from' the reservoir to the distributer.

A further object is to cause the oil to be delivered from the reservoir to the distributer at such periods as will properly lubricate the bearings, the delivery periods being automatically determined by the number of revolu- .tions of the windmill, thereby securing just the amount of oil required according to the actual operation of the windmill.

The delivery of oil-from the reservoir to the distributer is controlled by a valve mechanism, and a further object is to provide means whereby when a relatively thick or heavy oil is being used the valve mechanism will automatically keep the valve open for a relatively longer time than when a relatively light oil is being used, in order to give the heavy oil the longer time requisite for its relatively sluggish flow from the reservoir to the distributer.

Another object is to provide a device whereby oil may be conveyed from the sta tionary distributer to the rotating hub or sleeve of the wheel.

Another object is to provide a flexible oil distributing pipe which.has extreme dura- 4 bility.

Another ob'ect is to provide for automatically positively closing the valve after it has been opened, even though the wind wheel is not operating.

The accompanying drawings illustrate the invention, and referring thereto :Figure 1 is a side elevation of the upper part of a windmill, showing the complete apparatus form+ ing the invention.

Fig. 7 is a detail view of the clamping device which supports the timingmechanism, reservoir, and distributer. Fig. 8 is a side elevation of the air regulating screw.

1 designates the upper part of the windmill tower upon whichis revolubly mounted a head 2. The head2 has a vertical arm 3 which supports a wheel spindle 4, upon which is mounted'the sleeve or hub 5 of the Wheel frame 6. The arm 3 has a journal 7 in which a shaft 8 is mounted carrying a gear 9- which meshes with a pinion 10 mounted on the s indle 4. The gear 9 carries a crank pin 11 w ich operates the pitman 12, to which the urn rod 13 is connected by links 14. The rear 2 has an arm 15 to which is pivoted a rock lever 16. The end of the arm 16 has lugs 17 which project into slots in links 14. Fastened to the rock arm 16 is a. block 18 to which is connected the lower end of a link 19.

20 designates the case of a timin mechanism which is fastened to a vertical rod 21 by bolts 22, as shown in Fig. 4. The rod 21 asses through an eye bolt 23, as shown in igs. 1 and 7,and is clamped in position thereby. The eye bolt 23 is supported by a clamping frame comprising two plates 24 The lates 24 and 25 are arranged on opposite si es of the journal 7, the plate 24 having teeth 26, which bite the metal of the journal, the lower ends ofthe plates 24 and 25 being forced tightly against opposite faces of the journal 7, by means of a threaded stud 27 arranged above the eye bolt 23. The plate 24 may also be provided with a set screw 28, to positively lockthe clamp on the journal 7.

The rod 21 may com rise a pipe, as shown, and its upper end or t at portion which lies above the casing 20 of the timing mechanism is constructedto form a distributer 29. A distributer of this type forms part of the subject matter of the atent above referred to and therefore wi only be described 7 upper bearing of the pitman 12, and pipe e of these oil tubes is unique.

briefly. The distributer 29 is provided with a number of discharge openings having nipples 30, which are located at definite levels. Connected to some of the nipples are oil pipes 31, which convey the oil from the distributer to the bearings to be lubricated. In the present case there are four bearings to be lubricated and consequently only four pipes 31 are employed, therefore the other nipples 30 may be closed by plugs 32. Connected to the upper end of the distributer 29 is a reservoir 33, while a valve 34 is arranged between the reservoir 33 and the discharge points of the distributer. The valve 34 is normally held closed by a spring 35, and has a stem 36 adapted to coact with a lever 37 to open the valve when the lever 37 is depressed.

As the discharge openings ofthe distributer are located atdiiierent levels, so that the surface of the lubricant passes them in succession, the supply of lubricant is cut off from'them insuccession, the quantity of oil which escapes through the discharge openings varies inproportion to their relative elevation; thus the oil pipe a, which supplies the wind wheel hearing which requires the greatest quantity ofoil, is connected with the lowest nipple of the distributor, the pipe for supplying the bearing requiring the least amount of oil is connected with the highest nip le, and the other pipes are connected to t e intermediate nipples according to the relative demands of the bearings which they supply.

As'shown, one of the pipes (1 leads to the leads to the lower bearing of the pitman 12. Pipe b leads to the journal 7 for oiling the shaft 8, and pipe a conveys to a distributing ring to be described later. The construction Each tube com rises a coiled wire, the coils of which lie 0 osely together. When first used an extremely slight amount ofoil works between the coils and collects dust which, being exposed to sunand. wind, combines to form a skinor leathery casing which effectually seals the cracks between the coils and thus a perfectly flexible tube is formed having er treme durability.

The timing mechanism for periodically operating thevalve 34, is shown in detail in Figs. 3 and 4, and is housed within the casing 20 before referred to, and within the casing are three shafts 38, 39 and 40. Loosely mounted on the shaft 38 is a ratchet wheel 41, the spaces between its teeth being formed concave as shown. The ratchet wheel 41 has a hub 42 which is provided with a single tooth or dog 43, which operates an intermediate ratchet wheel 44, which is mounted on the shaft 39. The ratchet wheel 44 has a hub 45 which is provided with a single tooth or dog 46, which is adapted to operate anment of the ratchet wheel 44.

other ratchet wheel 47, which is loosely mounted on the shaft 40. A. rock lever 48 is loosely pivoted on the shaft 38 and has a 'head 49, which' is provided with a recess 56 fprmin an inclined face 51 and a ball retaining wall 52. As shown in Fig. 4, the head 49 has a flange 53 which lies behind the edge of the ratchet wheel 41, thus forming an inclosure for a ball 54. As the rock lever 18 is moved in one direction, the inclined shoulder 51 moves the ball 54 bodily with the rock arm, and the ball 54 being seated in a concave recess between two teeth of the ratchet wheel 41, thus turns the ratchet wheel 41 a distance equal to the stroke of the rock lever. When the rock lever is moved in the opposite direction the inclined face 51 moves away from the ball 54, and as soon as the retaining wall 52 strikes the ball 54 it moves the ball 54 back with the rock lever, the ball riding up overthe rear tooth and passing as many teeth in this manner as the ratchet wheel has been advanced by the preceding stroke. the ball dropping by its weight behind each tooth as it passes overthe tooth. so that when the rock lever has reached the end of its recovery stroke the ball is seated and ready to advance the ratchet wheel upon the next forward movement of the rock lever. As the ratchet wheel 41 is rotated its tooth 43 is moved around therewith, and it turns the wheel 44 the distance-of one tooth for each complete revolution of the ratchet wheel -11. In the position shown in Fig. 3, the dog 43 is in position to o erate the ratchet wheel 44 the distance 0 one tooth upon the next stroke of the rock lever 43. As the intermediate ratchet wheel 44 is rotated, its dog 46 operates the ratchet wheel 47 the distance of one tooth for each complete revolution of the ratchet'wheel 44, and. in the position shown in Fig. 3, the dog 46 is in position to operate the ratchet wheel 47 upon the next move- A weighted retaining pawl 55 is mounted on the shaft 39 for reventing backward movement of the rate et wheel 41. The ratchet wheel 44 is prevented from reverse movement by a rctaining pawl 56, which is yieldingly held in lace by a flat spring 57. The ratchet 47 is held from reverse movement by a? retaining pawl 58, yieldingly held in place by a llat spring 59. The head 49 of the rock lever 43, as shown in Fig. 4, has a grooved recess which receives a rod 66, the rod 66 being clamped in place in the groove by a washer 61 and bolt 62. The rod 61 extends out through an opening 63 formed in the casing 29, and fastened to the rod 69 by .an adiuslabh. clam 64 is an extension rod 65, the end of whie 1 has an eye 66, which articulates with an eye 67 formed in the end of the operatin rod 19 before referred to.

68 designates a carrier formed preferably of sheet-metal and having anextcnsion 69.

steam the lower end of which rests the extension 69. One end of the double rod is formed with a hook 71, and a coil spring 72 is confined between the hook 71 and the extension 69, the carrier 68 being capable of an upward sliding movement on the double rod 70, the spring 72 serving to retract the carrier on the double rod 70. The other end'of the rod .70 is extended to the upper part of the casing andis fastened to astationary stud 73. Mounted on the carrier 68 is an air cylinder 74, provided with a hollow piston rod 75 anddetail in Fig. 8, having one-face tapered off at'79. By adjusting the screw 78 up or down,-the air escape opening formed by the face 79 may be increased or diminished to regulate the assage of air therethrough.

Soldered or ot erwise attached to the lower,

end of the piston rod 75 is an arm 80, to

which is pivoted a'link 81, the upper end ,of-

the link 81 being connected to the lever 37 before referred to. Mounted on the ratchet wheel 47 isan operating stud 82, which by the rotation. of the ratchet wheel 47, is brought against the under side of the extension 69, and during further movement of the ratchet wheel 47 lifts the carrier 68 and cyl inder 74, compressing-the spring 72, and as the cylinder 74 is thn's raised gradually, the air flows past the regulating screw 78, through the hollow-pistonjrod75 into the cylinder 74 above the piston 76.

After the ratchet wheel 47 has moved a fur ther distance sufliciently to move the stud 82 out from under the extension 69, the spring 72 quickly expands and forces down the cylinder 7 4, and as the air is restrained. in its passage by the regulating screw 78, the air 1s compressed to a definite degree above the piston 76, which results in forcing down the piston 76 quickly, and the latter through the pistonrod 75 moves down the arm 80, and the latter draws down the link 81, which rocks the lever 37 and opens the valve 34, allowing oil from the reservoir 33 to flow past the valve 34 and fill the distributor. After the valve 34 has been opened, its spring 35 commences to react and force out the stem 36, which acts upon the lever 37 to lift the link 81 and. elevate the piston 76, and as the spring 72 is stronger than the spring 35, the carrier 68 and cylinder 74 remain in their normal position, and only the' pist'on 7 6 and piston rod are raised by thesprin 35 at a rate pro orti'onate to the outflow 0 air past the regu atin screw 78. Thus .if the screw 78 is adjuste to allow the air to pass freely tubes 95 and 96 toward the sleeve 5.

Y the tubes.

into the hollow piston, rod, the closing movement of the spring 35 will be very quick, while if the passage of air past the regulating screw is restricted to a considerable extent, the closing movement of the s ring 35 will be relatively slower. It is obvious that the timing of the closing movement of the'valve adjusting the regulating screw 78, so that when using a heavy 'oil the valve 34 will remain open a requisite length of time to allow the distributer to become filled, after which the valve 34 will be closed, while if alight oil is employed the screw 78 may be regulated to close the valve 34 after it has been open'by a relatively short time. By this device the closing movement of the valve may be regulated to the proper degree suitable for any character or" oil.

In order to convey oil to the sleeve 5, I providev a device illustrated in detail in Figs. 5

v,and 6, in which designates an external ring having an internal annular concave groove, the ring 90 being secured to the arms 6 of the wind wheel. an inner ring 91 of similar form, as shown, which is split at 92 to enable it to be contracted when being sprung into place within the ring. 90. The ring 91 is detachably secured. when in place by a set screw 93. The external ring 90 is cut away at diametrically opposite points to form recesses 94 which enable oil tubes 95 and 96 to be connected'with the tinner ring 91, as shown in Fig. 5. The other ends of the tubes 95 and 96 are respectively connected to opposite sides of the sleeve 5 and communicate with oil holes therein. Thus as the wind wheel rotates, the two rings 91 and 90 together with the oil tubes 95 and 96 rotate as an integral piece.-

As shown in Fig. 1, the discharge end of the oil tube a is arranged at a point compassed by the distributer, so that it will discharge oil into the groove within the inner rin 91, and as the wind wheel rotates the centri ugal action will hold the oil within the groove in the ring 91 and cause'it to flow through {the this device distributes oil to the rotating perfect manner, and there being no working joints employed, there is no chance for leaka e. Moreover, it 'will be observed that w en the windwheel stops rotating, the device will cease feeding oil to the sleeve 5, owing to the absence of centrifugal force which is required to cause the oilto move through When this'device is to be used on a wind mill on which the Wind Wheel revolves in the direction opposite to that of the wind wheel shown in the drawings, the inner ring 9 1 may be removed by unscrewing the set screw 93 and then contractingthe inner ring to allow it to disengage from the groove in the outer ring. The ring may then be reversed Within the ring 90 is- 34 may be regulated to a nicety bymeans of i Thus l and sprung back into place in the outer ring so that the tubes 95 and 96 will curve in the opposite direction, thus causing the oil to be forced through the tubes to the wind wheel bearing.

The rods 63 and can be moved relatively to each other by means of the clamp 64 to adjust the distance of the eye 66 from the rock lever 48. If it is desired to open the valve 34 with greater frequency the eye 66 may be adjusted closer in, which will with a given stroke of the pitman operate the rock arm 49 through a greater length of stroke, thereby causing the ratchet wheel 41 and associated gearing to be more rapidly operated. By'adjusting the rods 65 so that the eye 66 stands farther from the rock lever 49, the stroke of the latter will obviousl be shortened and the train of gearing will be operated at a slower rate proportionate to the speed of the wind wheel so that the valve 34 will not be opened so frequently. It is manifest that by this adjustment the oiling periods may be very closely regulated. The term period is not here used in. the sense of a certain elapsed time, but refers to a certain number of revolutions of the wind wheel which take place between each automatic This ad-' opening and closing of the valve. justment likewise permits of accommodating various lengths of pitman strokes as found in various sizes or types of wind mills and is. an important feature for the reason that this apparatus is designed to be applied to any make or size of wind mill in use. The entire sup; port of th apparatus is by means of the single clampi g device shown in Fig. 7 which is so constructed that it can be applied to some part of a mill, even though it may not be applied to the exact part as shown in Fig. 1, while the attachment of the rod 19 can be made to any convenient part of the mill which has a reciprocating or rocking motion, while the distributor is provided with sufficient oil discharge openings to enable oil tubes to be connected to as many bearings as are ever employed.
