Specification of Letters Patent.

Patented Jan. '7, 1919.

Application filed August 6, 1917. Serial No. 184,575.

INDoE, a citizen of the United States, re-

siding at Philadelphia, in the county of Philadelphia and State of- Pennsylvania, have invented certain new and useful Improvements in Oilers, of which the following is a specification.

The ob ect of my invention is the construction of an oilr or lubricator for elevator guide rails and the like, which will be simple and comparatively inexpensive to manufacture, durable in use, and which will not clog nor drip, and such other purposes as may hereinafter appear, and to that end consists in the novel features of construction, combination and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, wherein the preferred embodiment of my invention is illustrated,

Elevator oilersemploying fabric wicks as a means for conveying oil to elevator guide rails may be described as being of two types, viz: the straight capillary type and the capillary-gravity type.

In the former the wick contacts against the rail and as the oil is removed from the end of the wick by the' mechanical. action of the elevator, that is the movement of the elevator up and down the rail, the oil continues to rise. This method is more or less unsatisfactory as the pressure of the wick against the rail and its being moved at a rapid speed in contact, and the dust and dirt usually prevalent in elevator shafts, to a greater or lesser degree, causes the part of the wick bearing against the rail to become glazed, thereby mterrupting the circulation of the oil from the lubricator to the rail,

making it necessary to either replacewith new wicks, or to remove the glazed wick, and immerse it in kerosene, gasolene or some similar fluid to remove the hardened surface from the wick in order to'make the lubricator again operative. As to the second type described as capillary-gravity, thistype was designed to overcome the defective operation of the straight capillary type, and while the glazed wick defect has been corrected, another element of defectiveness is apparent, namely, the inability to control the flow of the oil causing a circulation of oil to the rail as long'as any remains in the lubricator. This actlon occurs at all times, especially at increased temperatures, no matter if the car is running or at rest. It is therefore obvious that when the car is in the pit at night, Sundays and holidays, the oil continues to flow in proportion to the carrying capacity of the wicks, and trickles down the guide rails, not only wasting the oil, but making it necessary to' employ drip pans, or placing bunches of waste to absorb the oil, the latter being, to a partial degree, an element of fire risk.

This present invention, known as the under-feed oiler, because of the position of the distributers, (being beneath the lubricant), is of the capillary-gravity type.

As capillary circulation cannot ,be controlled unless either the discharge end of the wick is disengaged from the rail or the submerged end is removed from the oil, I have designed the distributers in my lubricators to store the oil that has circulated during the idle periodsof the elevator and apply this oil to the rail on the first trip the car makes out of the pit. The advantage of this being. that I make good use of the oil that would have been wasted in other types of capillary-gravity oilers that do not provide storage typedistributers,

Another feature .of my device is the ability to use heavy oils or fluid grease and adjust a port so that the wick saturation can be maintained to a maximum that will not be affected by the low temperatures of' winter or the heat of summer; this is an important feature as numerous freight elevators while loading are exposed to low temperatures in winter.

While it is admitted that the co-efiicient of friction of oil is not as low as the 00- efficient of grease, and that the lubrication of vertical surfaces such as guide-rails of elevators is more diflicult owing to the inability to efficiently use a circulating system on accountof the oil running down the'surface, yet the construction of my lubricator is such that oil wastage is prevented, and that a maximum saturation of the wick is maintained, and that as the wicks which I employ do not contact with the rail surfaces, and are concealed and protected from dust and dirt, it produces a lubricator having many polnts of superiority, over the lubricators of the same type now in use.

Referring to the drawings the letter a represents a body, reservoir or receptacle for the oil, preferablyv of..the design shown, secured to the elevator shoe in any suitable manner; As here illustrated by means of a drilled pad (1 with the set screw 6 to any suitable attachment to elevator shoe.

Said reservoir a is provided with a suitable cover 6, hinged as shown at 0 to permit of ready ingress and egress to the interior of said reservoir.

A central distributer f is positioned equidistant between side distributers g and g as shown, the three distributers being grouped within the under part of said reservoir a. Said central distributer f is slidably mounted in pocket h recessed in under side of body a.

A spring 2' is provided between the rear wall j of pocket It and the rear part of said distributer f, for the purpose of holdin said distributer in contact with the rail and allows for free movement thereof for any lateral motion of the elevator, and holds said distributer so that it will not leave its contact with the rail in order that it may lubricate the face of said rail. Distributers g and g are slidably mounted in the lower part of reservoir (1 as shown, directly opposite each other. They are provided, in the same manner as the distributer f, with springs m and m positioned as illustrated, the reservoir or body a being bulged as at Z to provide s aces therefor, for the purpose of holding said distributers in contact with the rail is and they allow for free movement thereof for any lateral motion of the elevator, and hold said distributers so that they will not leave their contact with the rail in order that they may lubricate the sides of said rail.

Directly above pocket h an auxiliary pocket n is provided, as illustrated, in the under portion of the body a for the purpose of providing means of access for the wicks o to the distributers and for the purpose of allowing adjusting space for the tube 1).

These tubes p contain ports 9 drilled in a threaded portion of said tubes as shown, the opening being exposed to the oil reservoir a when the tube is turned upwardly permitdrawings, showin distributer f, a brldge wall t, having a slopting the oil to enter said port to increase the saturation. of the wick or to permit the oil to run by gravlty into the pockets at, thence to the 'distributers, if so desired. A metal strip 7* is employed to keep the wicks '0 taut. Limit stops 8 are provided to prevent the distributers g and g from being displaced ing surface, 1s provided as shown, the lower portlon thereof terminating at the face of said distributer to permit the oil to flow to the guide rail without interruption. Said bridge wall 25 also acts as a wall to the storeage space u, but does not extend to the full height of the distributer I so that theoil can flow over the top of the bridge wall into the space to withoutflowing over the top of the dlstributer, as when the distributer f is in contact with the guide rail is the storage space u is directly under the reservoir outlet. Passages v are provided to drain the oil that has been stored in space M permitting theoil to be applied to the rail as the elevator is in motion. Distributers g and 9' have the same construction in this respect as distributer f. The wicks o extend from the-bottom of the reservoir a upwardly and above the surface of the oil into, down and through the internal tubes p, emerging from the lower end of said tubes into the pocket n, thence to the distributer as illustrated.

A slot '10 is provided in the upper end of internal tube 39 to facilitate adjustment. I

As described the distributers have a double feed, one being an inclined surface taking the ordinary wick delivery, the other..com-

prising apassage or passages so formed as to drain the surplus oil saved during idle periods and delivering same to the guide.

The wicks 0 are a fixed part of the construction'and are not exposed to the dirt or dust, nor contacts with the rail, and are therefore not an active working part; that is, the distributers can be replaced without having to use new wicks, or dismantling the wicks. I

The distributers afford greater protection to the elevator shoes by picking up the grit instead of riding over it-this-reduces the wear of elevator shoes to a marked degree.

The ports 11 provided in the lower end of each tube 11 can be concealed by turning the tube downwardly, as they are drilled in the threaded portionof the tube, and when so concealed, make the operation strictly of the capillary gravity type using the lighter grades of oill The wicks 0 are mounted on metal strips, or on wire for ease of assembling and passed down through the cavity or socket n provided immediately above each istributer pocket or cavity h for the delivery or discharge end of the wick, which 'in practice comes to and lies at the outer eredduring the idle periods'of the elevator.

Passages or channels are provided to convey to the rail the oil thus saved during said idle periods, thereby increasing the lubrication as compared. with other types of oilers now in use.

In general practice one tube and one wick are provided for each surface, although a single wick and a single tube, as illustrated in Fig. 6, canbe used for lubricating the front surface of the guide rail-a lesser de- 20 gree of efiiciencv resulting.

I do not restrict myself to the exact de tails ofconstruction, combination and arrangement herein set forth, it being obvious that minor variations thereof not involving the exercise of invention may be made by the skilled mechanic, and such departure from what is herein described and claimed not involving invention I consider as within the terms and scope of my claims.
