JOHANNES TH. PEDERSEN, OF NEW YORK, N. Y.

LUBRICATOR.

Specification of Letters Patent.

Patented Nov. '7, 1905.

Application filed December 3, 1904:. Serial Ho. 235,296.

To (ti/Z whom it may concern:

Be it known that I, J OHANNES TH. PEDER- SEN, a citizen of the United States, residing at VVoodside, in the county of Kings, city and State of New York, have invented an Improvement in Lubricators, of which the following is a specification.

My invention relates to an oiling device of the visible-feed type adapted for use on machinery generally, and especially adapted and designed for automatic operation or working in connection with the exhaust-pressure from an engine or crank-case, particularly the engine and crank-case of an automobile. My improved lubricator or oiler is also by its particular construction equally well adapted for employment in connection with other different systems of lubrication, and the same may, if desired, be employed for the easy or quick oiling of machinery before the same is started, the automatic operation coming in evidence thereafter.

The object of my invention is to form adevice of the simplest and most efficient type.

In carrying out my invention I provide a suitable case or receptacle for the oil and regulatable means for admitting the same to said case. A pipe enters the receptacle and is adapted for connection to the exhaust-pressure of an engine or to air under pressure which enters the receptacle from any suitable source, and this pipe at its upper end is preferably provided with a gravity valve. A glass is provided for observing the height of the oil in the receptacle. Glasses are also provided for noting the visual feed. A device is provided for the quick release of too great a pressure. One or a series of pipes rises witl in the receptacle, passing through the bottom of the same, and within said pipes are needlevalves having seats in the base of the said receptacle and means for providing for the longitudinal movement of the said needle-valves to either seat or unseat the same in closing ofl the supply of oil or to regulate the extent of flow, and in connection with the device of my improvement I provide means so admitting the oil and controlling the supply of the same as to provide for an automatic starting and stopping pressure-feed, for gravity and pressure feed, and for gravity feed alone. My improved lubricator or oiler can also be employed in connection with a tank and pump system.

In the drawings, Figure 1 is a vertical longitudinal section and partial elevation representing my improved apparatus. Fig. 1 is a cross-section through the sleeve and inverted plan of the loose valve of Fig. 1. Fig. 2 is an end elevation. Figs. 3 and 4 are elevations at opposite sides representing details of the feeding mechanism. Fig. 5 is a vertical section and partial elevation, showing a moditied form of the invention. Fig. 6 is a sec tional plan at the dotted line a? w of Fig. 1, and in larger size for clearness. Fig. 7 is a vertical section through a case and devices of a modified form, and Fig. 8 is a partial vertical section and elevation of the central part shown in Fig. 7 and in the opposite position to said parts.

The case a is preferably of rectangular form and of cast metal and is provided with lugs a for securing the same to a suitable support or foundation. The front of the case is advantageously provided with a curved wall form ing a recess and containing a sight-glass tube (4 passing through the same and through the Walls of the recess at the respective ends thereof and communicating with the interior of the case or receptacle (0, in which the height of the oil may be visually noted. The case is provided with a cover 6, having a depending grooved edge for an intervening packing, the cover setting down upon the upper edge of the case and being secured thereto by tap-bolts 2. The case a centrally and along the bottom of the same is provided with a base-rib c perforated to produce an oil-channel 3, extending from which rib a is a tubular central projection a. The said oil-channel 3 is closed at the ends of the case by screw-plugs 4:, and the projection a maybe integral with or separate from the rib (0 The cover Z) is formed with a cylindrical flange 5, within which and integralwith the same and cover are radial arms and a central hub 6 The central hub is bored and interiorly threaded to receive the exteriorlythreaded neck 0 of the knurled cap 0. This neck 0 is hollow. The lower end is perforated and provided with a valve-seat, and a stem 5, having enlarged ends, passes clear through the neck 0 and knurled cap 0, the enlarged lower end of the said stern forming a valve against the seat at the lower end of the neck and the enlarged upper end of the stem projecting above the surface of the knurled cap to be pressed and forced down by the application of the finger. Surrounding the stem 5 and within this neck 0 is a helical spring 6, the function of which is to keep the enlarged lower end of the stem as a valve seated against the under surface of the neck.

The knurled cap a is provided with a radial opening 7, which bisects, or, in other words, communicates with the hollow interior of the neck 0. The eXteriorly-threaded portion of the neck 0 fits into the hub 6 and a washer intervenes between the upper edge of the flange b and the under surface of the cap 0 when the partsare screwed down tightly to place. will be appreciated that when the stem 5 is pushed downward by the finger against the action of the spring6 and the lower enlarged end of the stem unseated any pressure of air or gases within the casein excess of atmospheric pressure will then pass out through the hollow neck and through the radial communicating opening 7 to relieve the pressure within the case, as may be desired.

A pipe (Z, provided with a lower tubular portion cl, passes through the bottom of the f case at one side of the rib a and the same is secured to the bottom of the case, the pipe (6 rising within the case and being provided at its upper end with a valve 8, which seats against the upper end of the pipe. Connected with the lower end of the tubular portion d is a coupling (Z to which the end of a pipe is to be connected, extending from a suitable source of exhaust orfiuid under pressure which rises through the pipe (Z into the case.

Each sight-feed structure comprises a tubular body a with opposite apertures interiorly threaded at its lower end receiving a tubesection of glass 9, held in place by the sleeve h, which screws into the lower end of the tubular portion 6, holding in place the glass section 9, there being preferably washers at the respective ends of the said glass section to produce a tight joint. The upper end of the tubular body 0 is provided with a tapering neck 6, which passes into and, through the base-rib a" and bottom of the case. This taper neck 6 is provided with an opening to match or agree with the aperture 3 in the said base-rib, the upper end of the taper neck being provided with a screw-thread for a nut 10, which serves to hold the tubular body a and taper neck a firmly to the case and its base-rib, the tapering lit of the parts effecting a liquid-tight joint, obviating the necessity of a packing.

A pipe f is secured in the upper portion of the taper neck, and when the parts are in position this pipe passes through the case or receptacle a and at its upper end is secured to a sleeve 11, which forms a substantial continuation of said pipe, the said sleeve being exteriorly threaded and passing through the cover 6 and receiving thereon a nut 12, closing the aperture in the cover and tightly holding the pipe in position.

The tubular body a is centrally and axially provided with a nipple a, which extends down From the foregoing explanation it into the tubular portion, where the lower end is visible at the section-glass 9, and at the upper end of the opening passing through said nipple, and at the intersection of the same with the opening through the taper neck which agrees with the aperture 3 there is a seat for a needle-valve f". This needle-valve or pointed rod its the pipe f, passes through the same and through the opening in the tubular neck that agrees with the oil-channel 3, and at the upper end of the said nipple-valve means are provided for raising and lowering the same so as to bring the same to its seat at the upper end of the tubular body a or to raise the same above said seat. Alternate forms of such means are shown in Fig. 1. One means consists of a screw-cap f interiorly threaded to screw upon the upper end of the sleeve 11, the said screw-cap being pinned to the upper end of the needle-valve, so as to rotate the needle-valve with the rotation of the screw-cap. 1n the structure just described I prefer to form a packing-gland at the upper end of the needle-valve and upper end of the sleeve 11. The other means for raising and lowering the needle-valve comprise a screw-cap f centrally perforated for a prolongation of the needle-valve which extends through the same. This screw-cap f like the screw-cap f is received on the upper end of the threaded sleeve 11, and a lever-army is connected at the pivot 13 thereto to the prolongation of the needle-valvef, and a spring g is provided within the screw-cap f around the upper end of the needle-valvef, one end of which springis hooked toa pin of the needlevalve, (shown in Fig. 1,) and the other end bears against the under surface of the screw-cap. In the position of the lever-arm 9, Fig. 1, in line with the needle-valve, the same is raised off its seat at the upper end of the tubular body a. \Vhen, however, the said lever-arm r is turned down into a horizontal position, the pressure of the spring g will cause the said needle-valve to come tightly against its seat and close the aperture, passing through the nipple of the tubular body.

The sleeve b, whose upper end is exterior-1y threaded and received into the lower end of the tubular body a, is internallyshouldered at two places, the upper shoulder forming a seat for an internal ring It and the lower shoulder forming a seat for a loose valve if, said loose valve having a stem guided in the ring 7L and being forked or transversely cut through at its lower end, so as not to close off the opening from the sleeve in into the pipe end 15. This pipe end 15 is connected to the lower exteriorly-threaded end of the sleeve by a coupling 14. The lower end of the in; ternal ring 7/ is tapered to form a seat, and the shoulder of the valve if is likewise tapered, and this loose valve is free to rise and fall under pressure, as hereinafter described.

When in its elevated position, however, it

closes off the opening between the pipe end 15 and the tubular body (2.

The tubular projection or prolongation (K from the rib a is interiorly threaded, and connected thereto is a tubular body 2', having a valve or cook Z, and to the lower end of this tubular bod ye is connected a pipe end 15 and coupling 14 similar to the parts hereinbefore described. This latter pipe end, however, is to be connected to a pipe from a source of lubricating oil or fluid, while all of the other pipe ends 15 are tobe connected to pipes for conveying the lubricating fluid or oil to different parts of the machinery for their lubrication, the said cock or valve 2" being useful for closing OH or opening up communication through the tubular body e'. At the upper end of the tubular body Z there is provided a seat for the ball-valve 16, which is free to move in a chamber of appreciable area formed in the said tubular projection to.

I provide a pipe is, an exteriorly-threaded sleeve and nut 70 the sleeve 7r, nut 76 and pipe in being substantially an integral structure. The lower end of the sleeve ZJ is provided with integral projections spaced apart, and while the portion of the sleeve it" below the nut k is exteriorly threaded the portion of the sleeve 70' above the nut 70 and where the same surrounds the pipe Zr is tapering and provided at one side with a depression or recess 17 and at the opposite side with an opening 18, which passes clear through both the pipe and the sleeve. The lower threaded portion of the sleeve is provided with an opening 19, and this sleeve it passes through a threaded opening in the bottom of the case or receptacle and also through the bottom of the rib (Z3, the projections Z1 passing into the chamber at the upper end of the tubular projection a said projections 70 coming directly above the ball-valve 16 (see Fig. 1) and limiting the upward movement of said ball-valve when raised from its seat at the upper end of the tubular body Z. The location of these parts is advantageously central of the case or receptacle, and in view of the manner of connecting said parts to the case or receptacle the pipe/l: consequently rises within the said receptacle and it extends to near the cover thereof. Surrounding the pipe 76 is a pipe Z, which at its lower end is interiorly tapered to fit around the tapering upper end or inclined seat 76*, the lower end of the pipe Z havingan opening Z coinciding with the opening 18 and the base of the recess 17. A sleeve m, having a lower contracted portion exteriorly threaded, is adapted to pass through an opening in the cover Z, which is interiorly threaded to receive the same, and the taper end of the pipe Z passes up into the sleeve m. The upper end of the sleeve m is interiorly threaded to receive a sleeve-nut m, between which parts there is formed a gland for a packing.

The stem Z passes through the sleeve-nut m to a joint with the upper end of the pipe Z, so made that said stem Z and pipe Z turn together. At the upper end of the stem Z I provide a thumb-plate Z secured thereto in any desired manner, on one face of which thumbplate is marked the word Pressure, while on the other face the word Gravity is preferably marked. WVithin the pipe Z and above the upper end of the pipe 7a I prefer to employ a gravity-disk 20, which closely fits the. pipe Z, is provided with a small central perforation and an upper recessed face.

Figs. 8 and 4: are elevations from opposite sides of the sleeve 7; and the parts associated therewith. In Figs. 1 and 5 are shown in vertical section the relations of the said parts with the pipe Z, from Fig. 1 of which it will be noticed that the opening Z coincides with the recess 17 and that the opening 18 on the opposite side is closed off by the pipe Z, while in the view Fig. 5 it will be noticed that the opening 18 and the opening Z coincide and that the imperforate side of the pipe Zcovers or extends around the recess 17, the illustration Fig. 1 therefore providing a passage-way for the oil or lubricating fluid within the case or receptacle a through the opening Z up between the pipes Zn and Z, over the top of the pipe k, and down the same into the oil-channel 3, and from the oil-channel 3 by the central perforation of any tubular body, where the needle-valve is raised through said tubular body, where the dropping oil can be visually noted, past the valve If, and away by the pipe end 15. From the View Fig. 5 it will be apparent that the oil in the case or receptacle a may pass directly through the coinciding openings Z and 18 into the interior of the pipe 70 down into the oil-channel 3 for like use.

The receptacle or case a is preferably filled with oil or lubricating material from a supplytank by a gravity-flow or from a pump under pressure, the oil entering through the tubular body 2:, past the ball-valve 16, and through the chamber in which the same may pass into the oil-channel 3, up the pipe is, through the coinciding openings 18 and Z as shown in Fig. 5, into the case or receptacle until the same is filled to the desired extent, as will appear from the oil in the sight-glass a The seating of the ball-valve 16 or the closing off of the valve or cook Z, or both, will prevent such oil returning in the same direction. If the parts are now left in this position, the oil in the receptacle or case a will flow simply by gravity from said case or receptacle through the coinciding openings Z and 18 down into the channel 3 and therefrom to different parts of the machinery through the tubular body a and the parts connected therewith. This position may be advantageous in fully oiling-the different parts of the machinery before the same is started and before any pressure from the engine or exhaust is in evidence. To the operator this position is apparent by the word Gravity appearing on the face of the thumb-plate Z next to him. When the pressure fromthe exhaust, engine, or other source enters by the pipe (Z into the case above the oil therein and its effect is in evidence, the pipe Z is to be turned from the position of the parts Fig. 5 to the position of the parts Fig. l, in which the oil will pass by the opening Z up between the pipes Z and Z; and over the top of the pipe/t and down the same into the oil-channel 3. This rising oil contacts with the under surface of the gravity-disk 20, which is of appreciable weight and must lift the same from a seat on the upper end of the pipe 7a, and this disk 20 is raised in proportion to the pressure, and because of its central opening some oil will pass through into the chamber above the same and between it and the under surface of the stem Z, filling said chamber and producing therein a pressure equal to the pressure in the oil beneath the said gravity-disk, thus preventing the gravity-disk from rising too far and permitting the same, when the pressure is reduced, to seat on the top of the pipe 7; and the oil above the disk to gradually percolate through the opening in the disk 20 into the pipe in. This is the pressure position of the parts, (indicated by the word Pressure on the thumb-plate Z,) as shown in Fig. 1.

Should there be pressure in the case or receptacle ct'and a gravity-feed be desired with the pressure, the pipe Z is to be given a halfturn by the hand upon the thumb-plate Z bringing the parts into the position Fig. 5, where the oil will flow through the alined openings Z and 18. The tank may, if desired, be filled with oil or lubricating material by the removal of the knurled cap and its neck 0, which provide a passage down the flange 6. When the knurled cap 0 and neck 0 are in the position shown in Fig. 1, the case or receptacle a may be relieved of too great a pressure by depressing the stem by the finger placed on the upper end thereof, which unseats the lower end of the stem and forms a passage-way for the exhaust or other surplus pressure to pass through the hollow neck and through the lateral opening 7 in the cap 5.

In Fig. 5 and below the tubular projection cf 1 have shown that the device may be provided with a sight-feed like the sight-feed structure hereinbefore described and comprising the tubular body a and glass section 9, which is interposed between said tubular projection a and the tubular body 2', the valve if similar to the valve If, but reversed, having a seat at the upper end of the tubular body a. The form of invention shown in Figs. 7 and 8 provides an equivalent structure to the sleeve m, stern Z and tubular plate 2', stem 70/. and the openings Z and 18 and the functions performed thereby. In

these figures the case or receptacle is provided with a horizontal tubular part a from one side and merging with the bottom of the case and extending toward the center, bisecting the central portion. This tubular part is preferably provided with concentric collars, the inner one exteriorly threaded and the outer one interiorly threaded for the central outer pipe 0 and central inner pipe n, which are secured thereto. The inner pipe rises in the case to about the same height as the pipe 70. The outer pipe preferably extends through the cover and is terminated by a screw-cap 0 thereon and closed by suitable washers within said cap and between the same and the cover. The gravity-disk 20 is also advantageously employed in this construction. l/Vithin this tubular part a is a stem Z*, on the outer end of which is a thumb-plate Z This stem Z is provided with a transverse aperture 21, alining in a vertical position with the opening, which communicates with the oilchannel 3 and with the central aperture in the tubular part (Z5. The end of the stem Z* has a recess 22 and an aperture 24 passing through the same, communicating with the recess and also coinciding in one position with an opening 23 in the tubular part a communicating with the space between the pipes n and 0. The opening communicating through the bottom of the case with the oilchannel 3 is prolonged at one corner as a recess 26.

In the position shown in Fig. 7 the openings 23 and 2e coincide, so that oil in the case or receptacle a under pressure will pass from the case or receptacle and recess 22 through the openings 24 23 into the space between the pipes 0 and a, over the top of the pipe 71, down the same, through the openings 25 and 21 down into the oil channel 3, whereas if the stem Z" is given a half-turn, so as to reverse its position, the opening 2 1 is brought into coincidence with the recess 26 and the opening 23 closed off, as in Fig. 8, in which position, Fig. 8, the oil will flow by gravity from the case through the opening 24, recess 26, into the oil-channel 3.

In the foregoing similar characters of ref erence are applied to similar parts, and the parts in Figs. 7 and 8 not herein described carry the same characters of reference and perform the same functions as the same parts in the other figures and described in connection therewith.

The loose valve 7L hereinbefore described, normally rests upon the lower shoulder of the sleeve h, and its main function is to prevent the gases from the engine blowing back into the glasses and oil-receptacle. It is free to move up and down and it is kept in a more or less constant action through the vibration of the engine. This movement has a beneficial effect because the valve acts like the plunger of a pump on the oil in the pipes tending to force the same forward to and through the bearings.
