L'UBRICAT'OR.

To all 'whom 'it may concern Be it known that I, HARRY VissumNG, a citizen of the United States, and a resident of 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.

My present invention relates to lubricator devices in general, and more particularly to oil cups which are employed to furnish an intermittent feed of-oil to metallic bearing surfaces.

It has specialv reference to the provision of an improved type of cup of the character referred to by means ofjvhich oil is fed`to the bearing only while the machine is in operation and in `which such flow ceases upon stoppage of the machine. Devices so characterized are especially useful in connection With intermittently operated machinery, suchv as locomotive engines, automobiles, pumps, compressors and other machines in whichv guides, rocker boxes, stuffing boxes and non stationary bearings not only require continuous lubrication while moving but are otherwise not conveniently to be oiled by hand. Lubricating devices actuated by gravity alone are not satisfac tory in such situations, since, when the machinery is inoperative the lubricators must also be made', inoperative by closing a valve .and if such shutting-off be neglected even occasionallyor for a short time waste of oil is incurred.

The principal objects of my invention are the provision of an efficient and inexpensive device of the kind above specified, one which is to be cheaply manufactured, of low cost of maintenance, unlikely to become out ofV order or in need of repair and one which is uniform and certain in its operation; the provision of such a device having improved adjusting means whereby the oil feed mayy be regulated or controlled with much precision` and nicety and adjustment made without the use of tools; the provision of improved means whereby the device may be quickly and conveniently opened for replenishingor for direct feed to the bearing Whee required, without disturbance of the normal feed or the adjustment thereof; the

provision of improved means for holding the casing cover in'place .in order to prevent accidental displacement with possible consequent entrance of dust or foreign mat- Specication of Letters Patent.

ter injurious to the device or its operation or lto thebearing supplied thereby; together with such further objects as may be hereinafter disclosed.

In the attainment of the objects above stated, as well as certain -addi'tional advantages which will be apparent to those who are skilled in the art to which my invention pertains, I have provided the constructions illustrated in the accompanying drawings, wherein-- Figure 1 is a vertical sectional view of a device embodying my invention; Fig. 2 is a horizontal sectional view taken on the line lI-*II of Fig. 1; Figs. 3, 4 and 5 are vertical sectional views of further devices embodying my invention; Fig. 6 is an elevational view of the device of Fig. 5 taken at a `right angle thereto, and Fig. 7 is an uridei plan view taken on the line VIII-VIII of Fi l Ftefeiring now more particularly to Figs. 1 and 2 it will be noted that in carrying out my invention, I make use of a hollow body or shell 10, preferably of cast metal, here shown as" provided with a shank 1()a by means of which itmay be inserted in place. For a threefold purpose, viz.: to afford a seat for, and means for maintaining in place, the gravity actuated shut off device 11 and to provide means for a direct feed of oil I form in the floor of the shell an upstanding flange 11 by which the inverted cup or bell shaped member 12, havinga stem 13 with a passage 13 is supported. The chamber i4 foi-ined by the said flange 11n and bell 12 and containing the ball 11 is provided with a sloping bottom 15 which communi cates with the main oil reservoir 16 by means of a assage 17, formed in the floor 18 of the casing 10, and with the bearing by means of the passage 19 formed in the shank, 10.

i 'lo provide means for closely regulating the flow of oil from the main oil reservoir 16 through the passage 17 into the chamber 14, I employ a needle valve 21 seated at the point 22 where the passage 17 communicates with the reservoir 1G. The said needle valve -21 is adjustable vertically by means of its threaded engagement at 23 with a projecting web 24 formed across the to of the casing 10, the upper end 25 of the va ve stem being ,provided witha thumb nut 26 fixed thereupon whereby it may be rotated.

"fo .th .nd the casing l@ iii-ay be ing substantially the sama) viz.: The bear tu' ep-tti closed the entrance of ing is lubricated initially, (and thereafter foreign and to prevent accidental when required) by lifting the cover 29 and adjustment of the needle valve change Without the use of a lool; nut,-set screw or the like, employ the peculiar cover construction here shown, wherein it will be 'g J i. .1 .I 1.

n einen t adapted to cooperate vini the a beveled edge is the 2.9 haring a 'flange iwoppositely contact thermv th.. io prevent tilting of the com-:r 2Q it provided at its extreme edge opposite the point indicated at 30, with a ilat heel 3l. ilhc plate is also provided with a housing 32 ior a spring 33 thc upper end of which seats in the thumb piece 526. The said spring 33 being inserted under compression exercises, as above suggested, the double function of'eierting a downward pressure, holding the cover in position upon the casing and a lift on the stern 25 tending to prevent accidental change of adiustrnent of the valve 2l..

it" will `be apparent upon reference to Fig. l that the vertical disposition of the valve stein 23 and its arrangement relatively to the cover plate 29 here shown is advantageous in that the valve stern is less likely to beconie broken or bent in service than if it were arranged at-tlie side of the casing and that but a single spring (53) is requiredto maintain the valve and cover in position.

Referring now incre particularly to igs.

8 and 4f, it will be seen that the devices here illustrated are similar to thatof F ig. l save that the beveled surfaces 28a and 30g in Fig. 3 are "disposed in directions opposite to those shown in Fig. l, and that in l? ig. d instead, oi' surfaces beveled on one face only l einand insert-,between the spring 33 andthe bottom of the housing an antifriction bearing comprisingjballs 36 carried in, a groove 3f! andga bearing Aring 38 upon which the spring 33 is supported, the cover.' being. cut

away-as indicated a-tBS to facilitate ytipping thereof.'

'llhe operation ofthe'device oflig. l is as-follows, (the operation of'the other ein-- bodiments illustrated in Figs;t 3, .4: and 5 beturning it about the stern 25 'as may be desired, and inserting the spout of the oil can in the passage 18a. @il then dischanged will How into the chamber le and thence around the ball l1 into'the discharge pas llto the bearing. The needle valve 21 haring been previously adjusted for the desired volume of feed, lthe reservoir 16 is filled and the cover 29 replaced. The passage l? will then fill and as soon as the machine is put into operation the ball ll will be thrown off its seat, allowing oil to flow into the chamber ld until it reaches the level of the top of the passage 19^When it will be discharged therethrough, thus al lowing a continuous feed during the operation of the machine. jarring is sufiicient-to throw the ball ll ed its seat, such ball opposes no obstacle to the iow of oil While the machine is in operation,
