Specification of Letters Patent.

Patented Dec. 13, 1921.

Application filed March 29, 1920. Serial No. sea r71.

To all whom/it may concern:

Be itknown that I, GEORGE P. YOUNG, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Elevator- Oiling Mechanism, of which the following specification is a full disclosure.

My invention relates to a guide lubricator for elevators. Y

The object of the invention is to provide a stationary sight feed lubricator for do livering a properly alined flow of oil to the medial portions of the vertical guides of an elevator, and to deliver the same to the bearing surfaces of the elevator shoe, the latter carrying wipers to remove superfluous oil and to distribute the oil film uniformly throughout the vertical length of the guide.

Heretofore, the sight feed cup has been placed on top of the elevator or upon the counter-weight, where it is difficult of access for the proper adjustment of the oil flow, the result being that the said flow is generally incorrect and that it is generally made too great because of the difficulty of adjustment, and as a result oil collects on top of the elevator.

The features of the invention are more fully set forth in the description of the accompanying drawings, forming apart of this specification, in which:

T Figure 1 is a fragmentary elevation. of an elevator guide, showing my improved lubricator attached thereto. 7

Fig. 2 is a plan section of one of the guides, showing the arrangement of the oil passages therein.

Fig. 3 is a fragmentary front elevation of a guide showing oil grooves.

Fig. 4; is a front elevation, showing the relation of the wipers to the guide and to the oil passages therein.

Fig. 5 is a side elevation of the structure shown in Fig. 4.

Fig. 6 is a plan section through the rail shown in Fig. 4.

Without showing more of the apparatus than is necessary to disclose the invention, 1 represents the roof of the shaft, 2 the vertical guide-way to be lubricated. 3 the elevator car, 4 the'car shoe having a three-face bearing on the guide, and 5 represents spring-pressed wipers, (see Figs. i and 5), secured to the upper end of the shoe on .opposite sides of the guide, the wiping members'being suitable oildistributing pads or blocks. 1

At the upper end of the shaft is the sightfeed oil cup 6, having the usual drop adjustment into the upper end of a vertical conduit 7, placed at'the rear and adjacent the guide and preferably terminating at approximately the medial portion of the guide. At the lower end is an elbow 8 communicating with the horizontal ducts 9, the said ducts in turn communicating with the distributing ducts 10, in the bearing surfaces of the guide. I

The cup being stationary and accessible, can be easily adjusted to keep the oil flow constant and in proper quantity, avoiding waste, the danger of oil accumulation on the elevator, and at the same time enabling a far more uniform and efficient distribution of the oil to all portions of the guide bearing surfaces throughout theirlength.

In order to additionally guard against the accumulation of oil overflowing into the top of the car, I preferably form the top of the shoe with the chamfered portions 11, which act to wipe the oil inwardly toward the guide surfaces, and further function to flow any superfluous oil downwardly and inwardly instead of outwardly and downwardly on the outer surfaces of the shoe, from which oil would drop onto the top of the car.

Not only is the adjustment made and maintained properly and the oil flow efficiently distributed, but the oil is thereby definitely and positively confined to the shoe and to the guide surfaces to be lubricated.

This invention though simple, produces increased economy, efficiency, convenience of adjustment and constancy, also constitutes an added element of safety and lessens the gaged with said rail and wiper carried by said car engaging said rail bearing surfaces.

2. An apparatus for elevator lubrication comprising a stationary sight feed drop lubricator at the top of an elevator shaft, a vertical guide having bearing surfaces, a shoe on the car sliding on the guide and having wipers contacting the bearing surfaces, a vertical conduit dropping from the lubricator cup to an intermediate portion of the vertical guide, a conduit transversely through the guide, communicating with said vertical conduit and having terminal ducts delivering to the bearing surfaces of said guide, and means preventing the oil accumulation upon the shoe.

3. An apparatus for elevator lubrication comprising a stationary sight feed drop lubricator at the top of an elevator shaft, 2.

vertical guide having bearing surfaces, a shoe on the car sliding on the guide and having wipers contacting the bearing surfaces,

a vertical conduit dropping from the lubricator cup to an intermediate portion of the vertical guide, a conduit transversely through the guide, communicating with said vertical conduit, having terminal ducts de livering to the bearing surfaces of said guide, and the upper surface of the shoe be ing chamfered to drain superfluous oil inwardly toward the bearing surfaces.

' In Witness whereof, I hereunto subscribe my name, as attested by the two subscribing Witnesses.
