To all whom it may concern:

Be it knownthat I, DWIGHT F. KILGOUR, a citizen of the United States, and a resident of Lexington, in the county of Middle.- seX and Commonwealth of Massachusetts, have invented an Improvement in Lubricators, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to lubricators for the guide rails of elevators and other purposes. I It is an-improvement upon the lubricator shown in Letters Patent N 0. 1,089,060, granted to me March 3, 1914.

The character of the invention may be best understood by reference to the following description of an embodimentthereof illustrating the invention shown in the accompanying drawings, wherein,

Figure 1 is a side elevation of an elevator guide shoe and rail and a lubricator illustrating the invention mounted on said shoe;

Fig. 2 is a plan of the lubricator with its neck removed; a v

Fig. 3 is a rear elevation of the lubricator shown in Fig. 1; a Fig. 4 is a plan of the lubricator;

5 is a front elevation of the lubricator;

Fig. 6 is a plan of'a modified form of wick-supporting neck;

Fig. 7 is a front elevation of the neck shown in Fig. 6;

Fig. 8 is a plan of another form of wicksupporting neck; and

Fig. 9 is a front elevation of the neck shown in Fig. 8.

Referring to the drawings, the lubricator shown therein as illustratingthe invention comprises a receiver 1, conveniently cast from metal in cylindrical-form with a top 3 preferably integral therewith. The reservoir may be provided with a thick wick 4 for conducting the-lubricant therefrom to the. rail 'or otherzthing to be lubricated. To support and guidethe wick a neck 5 is provided curved upward and forwardly from The lower end of said neck may terminate in an elongatedbas'e '7 having a flange 9 fitting into an elongated aperture inithe top. of the reservoir and serving as a covertherefor. The neck preferably tapers forwardly as well. shown in Fig. 4: to present a constricted portion 11 to Specification of Letters Patent. t t t 9 7 Application filed August 21, V

said neck. 1 1 a The neck may be readily-adjusted to expose the opening. in the top and'allow-lubricant, to he poured into the reservoir therethrough. To accomplish this the reservoir may-have a lug 13 (Figs. 1 and 5) cast thereon and the'neck may have a pair of ears 15 depending-therefrom connected to said lugs by a hinge pin 17 which may be detachable fora purpose to he described. The neck may readily swing in .a contraclockwise direction (Fig. '1)about said pin as a fulcrum and expose the top opening.

To normally hold the neck in position for use with its base closing said opening, suitable latch means may be provided, typified herein as a coil spring 19, having one end attached to an eye in a lug 20 on the reservoir adjacent the top thereof and its other end curved to present a loop adapted to be inserted in an openeye 21 in a lug projecting rearward from said neck. 1 This spring will hold the neck base securelv onto the reservoir top and prevent rattlingof the parts. but may bereadily released from the eye 21 to permit opening of the neck in a contraclockwise direction in case the wick or the forward edge of the neck in traveling alongan elevator guide rail. strikes an o struction, such for :example, as a shoulder at the union of adjacent rails. The spring will permit the neck to rock and prevent injury to the lubri cator from such cause. a I 1 Preferablv the neck is of cast-iron or other heavy construction. With thefulcrum pin adjacent the left endof said neck (Fig. 1) the preponderance of the weight thereof'is at the right of said fulcrum'pin and assists the spring 19 in holding the neck base normally seated over said top opening.

The lubricator is illustrated herein as cooperating with a guide rail 23 of an elevator well along which the'usual shoe 2510f an elevator car- (not shown) is adapted to slide.

same is used. a bracket 27 may be provided having-1a flange 29 with a pair of eyes throughwhichbolts -st are entered end ss cured to said shoe. A base member may be mounted on said bracket and be provided with tandem lugs 35 depending therefrom, adapted to slide in an elongated slot in said bracket and allow said base to be adjusted toward and from the rail to vary the distance of the lubricator therefrom as required. To secure said base to said bracket a screw bolt 37 may be tapped in one of said base lugs 35 and press a clip 39 against the bottom of the bracket. This clip may have sutlicient spring to allow the same to be ten sioned and securely hold the parts together.

The lubricator shown in my patent re ferred to was pivoted to its bracket by a single lug located centrally, laterally beneath the lubricator. This allowed more or Jess wabbling of the lubricator and did not give it the stability desired. To overcome this objection the lubricator shown herein may be provided with a pair of ears 41 depending therefrom, widely spaced and preferably adjacent the sides of the lubricator. The base 33 referred to may have a pair of bosses 43 projecting upward therefrom and a horizontal shaft 45 may be entered through registering holes in said ears and bosses and be secured in position by cotter pins 47. The ears 41 are located somewhat to the rear of a vertical plane passing through the center of gravity of the lubricator so that the weight of the latter will tend to rock the same automatically in a contraclockwise direction (Fig. 1) and press the wick against the rail. This will serve normally to maintain the wick against the rail with a desired nicety of pressure to feed the appropriate amount of lubricant from the reservoir through the wick to the rail.

To limit rocking of the lubricator away from the rail, a stop may be provided conveniently in the form of a spring arm 49 having its lower end secured to the lubricator base 33 and its upper end free and adapted for engagement with the reservoir.

Normally there will be a slight space between sa1d arm and sald reservoir. but if the reservolr swings backward away from the rail it willbelimited by said spring arm and from being drawn by capillary. attraction through the wick; tov the rail. .For this purpose; a leek arm-511mm be' nreridedefas neearoa on a shaft 53journaled in a bore in said base 33 and having a handle 55 for controlling the same. When the lubricator is in use said arm is rocked to its position shown in full lines in Fig. 1, but when it is to'be held out of operation, it is rocked in a clockwise direction up against the bottom of the reservoir to a position shown in dotted lines in Fig. 1, in which it is someu hat beyond the dead center of said shaft. In the course of this movement said arm "will rock said reservoir back against said spring arm a9 and thereby tension the latter so that said spring arm will serve to maintain the reservoir against said lock arm and hold the latter in its active position.

Various necks may be provided for the lubricator according to the form of wicks required. Y

In Figs. 6 and 7 is shown a neck 57 similar to that shown in Fig. 1 with the exception that instead of being flattened vertically it is wider and flattened horizontally. The base 59 of the neck 57 maybe the same as that of the neck 5, so that it may readily fit the opening in the top of the reservoir and be substituted therefor. To accomplish this substitution, it is merely necessary to release the latch spring 19, withdraw the pin 17, and substitute the neck 57 for the neck 5.

In some cases it may be desirable to have the wick engage not only the front edge of the rail, but also the sides of the rail. To accommodate such a wick a neck 61 may be provided as shown in Figs. 8 and 9. This neck has outer, tube-like portions 63 and an intermediate, tube-like portion 65. The former receive wicks 67 for engagement with the sides of the rail, and the latter receives a wick 69 for engagement witn the edge of the rail. The side wicks have ends projecting somewhat beyond the intermediate wick supported by extensions 63 at the outer sides thereof. The neck 61 may be provided with a base 71 similar to the bases of the first two necks described, so that the neck 61 may be readily substituted for the others.

It will be apparent that the parts are so standardized that the various substitutions may be quickly and readily made without any change in the construction or without the use of a tool."

While the lubricator has been described herein more particularly in connection with its use for lubricating elevator rails, it will be understood that it is not'limited thereto, but may be used for lubricating shafts and other purposes.
