Application filed October 16, 1920. Serial No. 417,340.

To all whom it may concern Be it known that I, HENRY J. SHAvnns, a citizen of the United States, residing at Goldsboro, in the county of Wayne and State of North Carolina, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

My invention relates to a new and useful improvement in lubricators that are designed to force heavy oil and flake graphite to the cylinders of a locomotive.

An object of the present. invention is to provide a lubricator wherein the oil and flake graphite is first poured into a funnel or large cup from which it is drawn into a reservoir in the form of a cylinder. In this cylinder is a piston which is to be under a slight pressure, and in the bottom of the cylinder is a port with an adjustable valve therein so that the amount of oil or graphite fed therefrom may be regulated as desired. From the first mentioned cylinder the oil is led into second cylinders from which it is forced out by compression to a pipe leading to the cylinder of the loc0mo tive. These last two mentioned cylinders being operated by a small motor.

Still another object of the present inven tion is to provide a lubricator that is very compact in nature, highly efficient and capable of forcing the oil and graphite under compression to the cylinders of the locomotive.

Still another object of my invention is to provide a lubricator that is simple in operation, relatively cheap to manufacture and quickly and readily assembled.

With these and other objects in view asv will be disclosed as the invention proceeds my invention consists of certain new and novel constructions and combinations of parts as will be hereinafter more fully described and pointed out in the drawings.

Figure 1 is a side elevation partly in section of my improved lubricator;

Fig. 2 is an end view partly in section; and

Fig. 3 is a detail of the worm and crank arms for driving the lubricator.

Referring now in detail to the several figures there is shown a base 1, on which is mounted a motor 2, although it is to be understood that any form of driving means may be employed.

A standard 3 is shown in which is mounted the worm gear at which is driven by the worm 5 of the motor shaft.

Two crank arms (5 are revolved bv the gears to which cranks are secured and connecting rods 7, the same in turn being con nected to the head 8 mounted on the slide bar 9. I

This bar is supported at its one end by the standard 10 and at its other by the malrrhousing 11 of the lubricator. I

Th1s housing 11 is in turn supported by the brackets 12 which are bolted to the base 1, as shown. Mounted in this housing are the two cylinders 13 and l t to which are bolted the heads, 15 and 16. As the cylinders and heads and cooperating plungers are identical a description of one will suflice. Referrmg now in particular to Fig. 1 it will be seen that the head 16 extends inwardly for a greater portion of the cylinder, is provided with the packing rings 1? and is beveled at its inner end and provided with the projecting portion 18.

Operating in the cylinder is the hollow plunger 19 which is provided with the upper or lnlet port 20 and with the larger outlet port 21 formed in its under surface. Connected with this plunger is the rod 22 which extends through the cylinder head 23 and the stuifing gland 24 and is fastened to the heretofore mentioned sliding head 8.

This hollow plunger snugly fits the head 16 so that when the same is operated it will compress the air in the plunger on its for wardstroke and form a vacuum on its rearward or back stroke.

Extending through the lower portion of the cylinder is the neath the same is the check valve 26 secured to the coupling 27 in one side of which may be secured a jet pipe 28 while another pipe 29 leads to the cylinder of the locomotive. Also leading to this coupling 27 (Fig. 2) is the pipe 30 which is an auxiliary oil feed provided in case the operating plungers should be in any way damaged or become inoperative.

Referring again to the several figures, it will be seen that bolted to the housing 11 is the reservoir cylinder 31 in which is provided the piston 82, and entering the head of this cylinder is a pipe 33 for admission of a slight amount of steam. Secured at one side of this feed cylinder is the filling cup 84 with the valve 35 therein.

Extending through the base of the cylinport 25 and directly be der 31 is the central discharge opening 36 and across which is placed the valve 37 which. is regulated by the movement of a handle 38 connected therewith.

Below this valve is placed a sight tube 39 so that the flow from the reservoir cylinder may be seen and regulated as desired. Be

neath the valve 37 there is a small port 40 for the admission of a slight amount of'air, this port being connected to a check valve 51.

From the opening 36 extend the two feed channels e12 which lead to the two cylinders 13 and Also extending from the sides of the cylinder 31 are the two pipe lines 30' in which are the valves 43 and the sights 44: to which are connected the aforementioned pipes 30 so that an auxiliary feed is provided, if ever necessary.

The operation of the lubricator is therefore as follows: Oil and flake graphite or any other proper lubricant will be first poured in the cup 34 and the piston 32 raised which will draw the same into the cylinder 31, the valve of course afterward closed. Steam will then be admitted to the pipe 33 so that a constant pressure will be kept on the piston.

The flow or feed of the lubricant will then be regulated by first looking through the sight 39 and turning the handle 38 on the valve 37, until the proper feed is determined. The motor will be started and presuming the plunger 19 is in the position shown in Fig. 1, as it is driven forward by the revolving of the worm gear 4 and its cooperating parts, the air and the oil that has passed through the several ports, and has been drawn by the rearward movement of the plunger through the inlet port 20 into the plunger will be compressed. That is, as soon as the port 20 passes the projection 18 and the feed channel 42, and the piston will continue to compress until the discharge port 21 alines with the port 25 when it will 7 be forcibly blown into the pipe 29 leading to the cylinder of the locomotive. The jet pipe 28 being used if desired, to further force the lubricant to the cylinder.

As the plunger begins its rearwardv stroke the check valve 26 will close and a vacuum will be formed in the plunger until the inlet port 20 registers with the feed channel, when the oil will be drawn into the plunger and the operation repeated. A small amount of air will be drawn from the port 40 along with the oil from the reservoir which is desirable. It will be seen that the flow of the lubricant is partly by gravity, partly by pressure of the piston in the feed cylinder or reservoir, and partly by the vacuum caused by the return stroke of the plunger, thereby assuring a proper feed of the lubricant; while the flow to the cylinders of the locomotive is assured by subjecting the oil and air to compression in the plungers and by providing a blower if found desirable.

From the foregoing it will be seen that I have provided a lubricator that is positive in action; may be quickly regulated as to the proper feed, compact in nature, and efficient in service.

Also an auxiliary feed is provided so that in case of a break-down of the lubricator the cylinders of the locomotive may still be sufliciently lubricated until the lubricator isrepaired.

Many slight changes might be made in the arrangement and positioning of the parts without in any way departing from the spirit and scope of the invention.
