LUBRIQATOR.

i, Naeoaml.

i 'To a/ZZ whom, it may' cora/caw@` Beit known that I, ALBERT L. MATTn'soN,a

citizen ofthe UnitedStates, residing at`Bat- 4'tlecreelL in the countyv of'Calhounand State of Michigan, have invented a certain new and useful Lubricator, of which the following is `a specication, reference being had therein to 'the accompanying drawings.

be associated with Athe steam-supply pipe to convey o il directly to the cylinder and which is capable of being easily regulated Vto raise the lubricant to the desiredtemp'erature and maintain it in a properly-heated condition, so

that the same will be eifectivelyliquefied inl the coldest weather, thus insuring the feeding of the-oilin proper condition at all times to the cylinder.

' Thev invention relates particularly 4to the construction of the lubricator, the manner in which the heating of the oil and its maintenance in a properly-heated condition is con-l trolled and regulated, and in connection therewith the means by -which the water of condensation is supplied to the oil-reservoir and sight-feed tu be and maintained atl the requisite temperature, and in the manner in which the oil is delivered from the lubricator and its liquefaction maintained up to the instant of its discharge from the lubricator.

A further objectof the invention is to provide, in connection with acondensation and oil-discharge pipe, a steam-heating chamber for the oil-reservoir and meansl for regulating the supply of steam to said chamber and also cutting off said supply altogether. f

' With the above and other objects in View, the nature of which will more fully appear as' the description proceeds, the invention consists in the novel construction, combination, and arrangement of parts, as hereinafter fully described, illustrated, and claimed. In the accompanying drawings, Figure 1 is a diametrical longitudinal section through a lubricator embodying the present invention. Fig. 2 is a similar section taken at right angles to Fig. 1. Fig. -3is atop plan View of the lubricator. Fig. 4 is a'cross-section-through the lubricator, taken in line with the oil-discharge tube. Fig. 5 is a cross-section taken through the lowerportion of the lubricator.

lThe lubricator-contemplated in this invention comprises an'oil-reservoir 1, which is preferably of cylindrical form, as shown, although any desired shape may be given thereto. This reservoir in carrying out the present invention is provided in its upper end' with a condensation-chamber v2 and in the bottom with an automatic steam -heating lchamber 3, the said chambers practically covering the entire cross-sectional area of the top and bottom of the reservoir, as shown.

Extending between the chambers 2 and 3 is a combination condensation and oil-dischargel pipe 4, which communicates with both of said chambers and-is preferably cast or formed integrally therewith and in one piece with the body of the reservoir.

'Thereservoin the Walls of the chambers 2 and 3, and the condensation and oil-discharge pipe 4, above referred to, are all made in one piece under the preferred embodiment of this invention,

A globe-shaped condensation-chamber 'extends upward from the top'of vthe reservoir and communicates at its bottom with the internal condensation-chamber 2, 'as'shown, and a condensationt1p1be 6 extendsfrom the upper end of the pipev 4 upward into the upper portion' o f the chamber 5. L

7 represents the oil-pipe, which connects at its lower end with the valve-casing 8, located adjacent to the lower end of the' reservoir and carrying.- the feedcontrol needle-valve 9 and the drain-valve 10. The opposite upper end of the oil-pipe is arranged near the top of the reservoir to receive the oil as it is raised by the water of condensation and overflowsinto said pipe. f

Communicating with the upper'portion of the reservoir is an oil-dischargepipe orftube 11.V This tube leads from thefcentral pipe 4 outward through the'reservir, where it connects With a coupling 12, which receives the upper, end of 'a sight-feed glass or tube 13, the lower end of whichconnects with the valvecasing 8, above' referred to.

14 designates an oil-dropping tube or nozzle extending from the valve-casing 8 upward into the sight-tube 13.

15representsthe tube which receives the water of condensation from the chamber 2 and carries the same into the bottomof the oilreservoir 1, the same being controlled 4by a Water-admission valve 16, located at the upper end thereof, as shown in Fig. 1. In the IOO IIo

bottom of the reservoir, beneath the pipe 15, is arranged a drain-plug 17.

At one side of the reservoir 1 is arranged an oil-gage 18, which communicates with the top and bottom portions of the reservoir and indicates the oil-level therein. The reservoir is also provided with an oil-filling plug 19.

2() designates a union at the bottom of the reservoir, by which the lubricator is connected into the steam-supply pipe leading from the boiler to the cylinder or steam-chest, said union communicating directly with the steamheating chamber 3 and the pipe 4.

The oil in the reservoir is heated by the steam in the heating-chamber 3, which is advantageously located in the bottom of the reservoir, covering the entire bottom thereof and draining itself automatically into the steamsupply pipe, the walls of said chamber being thus constantly maintained in a highly-heated state.

Water is supplied to the oil-reservoir and sight-feed glass through the combination condensation and oil-discharge pipe 4, through which the oil also passes on its way to the steam-supply pipe and cylinder of the engine. The oil does not passoutside of the lubricator-body eXcept as it passes through the sightfeed glass` so that it is impossible for the oil to become chilled on its way to the cylinder. This makes it practicable to use the heaviest oils inthe coldest weather.

By locating the heating-chamber in the bottom of the reservoir the heat therefrom riseseasily and rapidly. A great advantage of the invention also lies in the fact that it requires only one pipe to furnish condensation for both the oil-reservoir and the sight-feed glass, heating the water of condensation and providing means for conveying the oil to the steam-supply pipe and cylinder without any liability of the oil becoming chilled on its way.

The pipe or tube 4 where it extends through the chamber 3 is provided with a small hole 21, and said hole is controlled by a hand-operated valve 22, 'which provides for cutting on communication between the pipe 4 and chamber 3, the stem of said valve passing through the chamber 3, as shown in Fig. 2. When the valve 22 is opened, the chamber 3 fills with steam and raises the oil to a scalding heat in a very short space of time. By adjusting said valve the /degree of heat may be varied to suit conditions. In very hot weather the valve 22 may be entirely closed, leaving the lubricator as cool as the ordinary lubricator.

It Will be observed that the lubricator is simple in construction and free from narrow and tortuous passages, an objection to whichl many lubricators are open.

Having described the invention, I claim as new- ,l

1. Alubricator comprising an' dil-reservoir; a steam-heating chamber located injthe bottom thereof; a condensation and oil-discharge pipe extending through the reservoir and steam-heating chamber, and means for controlling communication between the said pipe and steam-heating chamber.
