To all whom it may so a-cm it known that l, Paras G. MacGnnoon, a citizen of the United States, and resident of the city, county, and State of New York,

have invented certain new and useful improvements 111 Contact-Odors, of which the iollowing 1s a specification.

This invention relates to a device for oil-, mg the contact members or an electric clr-j cuit closing device.

The object of the invention is to provide a device or an attachmentespecially adapted for use with street car controllers for reducing the wear and friction between the contact members.

standard construction.

In the drawings like parts or the several views have been given the same reference numeral.

Figure 1 is a sectional plan view of a por-' tion of a controller showing the oiling device attacheo thereto. Fig. 2 is a side elevation of a portion of Fig. 1. Fig. 3 is an enlarged sectional view on the hue 3-3 of Fig. 1. Fig. i is an enlarged sectional View of the controller, such as 1, 2 and 3, are rotatively mounted upon a shaft 4 and op:

erated in the usual. manner by means of 'a hand cranlr or lever. not shown. The contact lingers 5 and 6 are carried by resilient members, such as 7, upon a suitable support 8 attached to the base of" the controller. These parts may be of any standard construction for a device of this natureand no novelty is claimed for these features.

The oiling device consists of a number of blocks of absorbent inate1'ial,'such as felt, shown 9 and 9, the block 9 may be partially inclosed on two sides by a strip of in sulating material 10 and mounted at one end of a resilient member 11, which is attached at its opposite end to the contact finger 5. The resilient member 11 is preferably formed so that when the same is in position,

the surface of the block 9 projects ing a portion of the oil or lubricating material with which it is saturated to the surface thereof and then as the contact is rotated the oil will be distributed over the face of the contact. It will be understood that a number of these absorbent blocks are provided and positioned over each series of contacts, as shown in Fig. 2.

For supplying oil or lubricating material to the absorbent blocks, a flexible tubular member 12 is provided. This flexible tubular member extends through the series of absorbent blocks, as shown in Fig. 2, and is provided at its upper-end with a funnel shaped member 13. At the points where the flexible tubular member 12 passes through the absorbent blocks, a series of openings, such as shown at 14 vand 15 in Fig. 3, are provided. These openings decrease in size from the upper to the lower end so that when the oil is poured into the receptacle 13, filling the flexible tubular member 12, the same will be supplied to and absbrbed by the blocks in substantially uniform amounts. As the oil is absorbed the level of the same in the tubular member 12 falls so that the period of time during which the same is supplied to the upper block is less than that for-the lower blocks. The decreasing size of the openings thus provides for a uniform supply of oil.

In the modification shown in Figs. 4 and 5 a cover 16 of insulating material is positioned over the contacts and the absorbent blocks 17 project through openings therein so as to engage the contacts of the controller in the manner just described. The absorb ent blocks are mounted in a movable holder 18 and are resiliently held in position by means of a spring 19 positioned in a retaining member 20 mounted upon the cover 16. A flexible tubular member 21 supplies the oil to the absorbent blocks in the manner just described.

In the modification shown in Fig. 6, the construction is similar to that described and shown in Figs. 4 and 5, except that the cover 16 is omitted and an insulating support 22 substituted, which carries the series of absorbent blocks.

g isms is It Will thus be seen that each series of contacts is provided with an independent oiling device and that the flexible tubular member provides "convenient means for supplying a uniform amount of oil to the absorbent members simultaneously and at the same time permitting an independent rela the movement of the blocks when the contacts of tlie'controller are rotated Whatl claim is;

Lin a device of the class described, the combination with' a series of movable. contacts, of a series of absorbent members each positioned to engage one of said contacts, and means for supplying oil simultaneously to said absorbent members, said means being adapted to permit an independent movement of said members.

2. In a device of the class described, the

combination with a series of movable contacts, of a series of absorbent members each positioned to engage one of said contacts, and means connecting said members and adapted to supply oil simultaneously thereto and to permit an independent movement thereof.

3. In a device of the class described, the combination with a series of movable contacts, of a series of absorbent members in sulated from each other and each positioned to engage one of said contacts, and means for supplyin oil simultaneously to said absorbent members, said means being adapted to permit an independent movement of said members.

4. In a device of the class described, the combination With a series of movable con tacts, of a series of absorbent members each positioned to engage one of said contacts, and flexible members connecting said mem bers and adapted to supply oil simultaneously thereto. and to permit an independent movement thereof.
