SPECIFICATION formngvpart Of Letters Patent NO. 708,022, dated September 2, 1902.

Application tiled August 3, 1901. Serial No. 70,710. (No model.)

To a/ZZ whom it may concern,.-

Be it known that I, FRANK CARTLIDGE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to lubricators or oilers for lubricating machines of various kinds and is especially designed to furnish means whereby one or more bearings or devices may be supplied with oil fromacommon source of supply and means whereby the oil will be allowed to iiow when the machine is started and stopped as the machine is stopped or a determined amount of oil brought into position to be presented to one or more bearings.

It consists inl the novel combinations and such operative mechanism as will be more speciically described and claimed hereinafter.

In the drawings, Figure lis a sectional view of a lubricator embodying a portion of this invention. Fig. 2 is a plan viewof the same. Fig. 3 is a sectional view on the line 3 3 of Fig. l. Fig. 4 shows a modified form of construction. y Y

A represents an oil-receptacle adapted to contain a supply sufficient to run the machinel anydesired length of time. It is provided with lugs a a for attaching to a convenient support. A vertical valve-stem b, running through the receptacle, is secured to a valve B, provided with one or more chambers b' and a depending tubular extension h2 of smaller diameter. The valve B and' its extension b2 it in a casing o. at the bottom of the receptacle A. A by-pass a2 in the casing leads from the receptacle to a point below the valve and is adapted to furnish communication at times through an opening b3 in the tube h2 and from thence th rough a pipe C to the bearing to be oiled. Ports a3 in the casing register at times with the chambers b and furnish means for illing said chambers. As the valve is oscillated said chambers are brought to register with openings to outlet-pipes D D', which run to bearings to be supplied with a determined amount of oil. The upper end of the stem h passes out through a bearing in 5o the top of the receptacle A and has an armature E secured thereto. Electromagnets F F" are mounted on brackets f f on the receptacle A in such position as to attract the ends of the armature E and oscillate the stem b. AspringG holds the armature normally7 away from the magnets, and in this position the opening b3 is out of register with the by-pass and the chambers b' are in register with the ports 0.3, allowing the chambers to be filled; Whenv a current is sent through the coils of the electromagnets, the

armature is attracted, thc stem h is turned,

Aand the opening b3 brought to register with the by-pass, allowing the oil to iiow out through the tube C to the bearing. At the same time the chambers b' are brought to register with the openings to the pipes D D and their contents allowed to discharge. A set-screw e in the armature E is used to adjust the amount ofmovement of the stem, and consequently the iiow of oil.

In the moditied form of construction shown in Fig. 4 the lower end of the stem b is bored to form an outlet to the pipe C, and the oil is admitted through a lateral opening b3, which registers with an opening a4 in a seat (1,5, pro-V vided at the bottom of the receptacle for the stem b. Normally the passage is closed; but

when the stem is turned and the openings within the scope of this invention, which I do not limit to the exact construction shown; but

What Iclaim is- 1. vIn a lubricating device, the combination of a receptacle, a casing at the bottom of said receptacle, inlet and outlet ports in said cas-l ing, a valve in said casing with chambers communicating alternately with said inlet and outlet ports, a tubular extension on said ing, a valve in said casing with chambers communicating alternately with said inlet and outlet ports, a tubular extension on said valve, a by-pass leading from the receptacle to said extension, a lateral orifice in said extension adapted to register with said by-pass, a stem for said piston and means for turning said stem.
