Serial No. 339,692.

It is the purpose of my invention to supply an apparatus which, while adapted to use in connection with mechanism of many kinds, is especially adapted to the oiling of the moving parts of automobiles, motor boats and the like. Generally stated, my invention consists in a suitable reservoir or receptacle which shall be supplied, automatically or otherwise as desired, with oil, and an indicator easily accessible to the operator, whereby upon moving a pointer to appropriate points thereon, oil will be supplied at the desired time and in the desired quantity to the point designated on the indicator.

The apparatus herein illustrated and described disclose two forms of many in which my invention may be embodied. One of them simpler and less expensive than the other, will be described iirst.

Referring to thedrawings Fig. 1 is a vertical sectional view, certain parts being shown in elevation, of a simple form of apparatus embodying my invention; Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1 and looking in the direction of the arrows;

Fig. 3 is a plan View of the apparatus shown in Fig. 1; Fig. 4 is a plan view taken on the line Al--ft of Fig. l; Fig. 5 is Ea vertical seotional View, certain of the parts being shown in elevation, of a more elaborate form of apparatus embodying my invention; Fig. 6 is a vertical sectional view of a part of that which is shown in Fig. 5. taken at right angles thereto; Fig. 7 is a plan View taken on the line 7 -7 of Fig. 5; Fig. 8 is a plan View taken on the line 8-8 of Fig. 5; Fig. 9-is a plan view of the upper or index plate of Fig. 5; Fig. 10 is a horizontal sectional viewtaken through the several discharge ports of Fig. 5.

Referring first to Figs. 1 to 4, both inclusive, 1 represents a reservoir or tank, preferably of metal, provided with a filling plug 2. 3 is the cylinder of a pump within the tank provided with a piston 4, preferably 'having a cup leather 5 as its packing, which through connecting rod and eccentric 7, isoperated by a crank 8 on the out-side of the reservoir. 9 is the inlet port for the pump which discharges through its open lower end 10. 11 is a shaft ioosely journ alled near its upper end in the top of the reservoir, as at 12, and at its lower end is a bearing 13 in the pump casting 14. 15 is a disk fast `on the end of the shaft 11 and provided with a seating spring 16 and a series of holes 17, see Figs. l1 and 4', each of which registers with an appropriate tube 18, which extends to the part of the mechanism to be lubricated by it. It will be noted that the tubes 18 are so `located that each registers with its proper opening 17 in the disk, but that they are not spaced in straight line as are the holes. This is so that there may be more space for the proper engagement of the tubes with-the bottom of the pump castlng 14 and also so that thetubes may extend therefrom to the parts they are respectively to lubricate more directly and conveniently than would otherwise be possible.

19, see Figs. 1 and 3, is a pointer on the upper end of the shaft 11 which co-acts with an indicator plate 20 on the upper side of the reservoir, which plate has a series of indicia 21 designating the parts-fan shaft, steering gear, etc.-to which the tubes 18 extend respectively.

The operation of the parts thus far described embodied in a simple form of apparatus is as follows:

Oil is put in the reservoir 1, wholly or partially filling it as desired. The pump is ordinarily submerged in the' oil. At such time as the operator desires, which will depend upon the time that has elapsed since the last vpreceding oiling, the extent to which lthe mechanism has been in motion and the character of the work performed by it, the operator. moves the pointer 19 in succession to such `of the indicia 21 on the index plate 2O as designate the parts respectively he desires to lubricate, and as the pointer reaches the desired indicia in succession and comes to restthereat, the operator turns the crank 8 such number of times as will generate the requisite pressure in the oil chamber below the pump to inject oil through the approf prite tube 18 to and upon the part to be lubricated. After lubrication of the desired parts the pointer will be returned to its primary or a neutral position midway between any two of the indicia, as shown in Fig. 3.

When the pointer is in this position the holes 17 in the disk 15 will likewise be at a neutral point, i. e., not in registration with the tubes 18, so that there will be no passage of oil through them and thus none to thevparts in excess of the am'bunt desired by the operator.

Referring nowto Figs. 5 to 10,1both inclusive, 22 represents the reservoir, 23 the shaft, 24 the pointer and 24u the index plate provided with indicia 21. These parts are or may be substantially the same as above described. 25 is an oil inlet pipe which connects with the usual oil pump of the engine diagrammatically shown as a pump similar in construction and operation to that illustrated in Figures 1 and 2 and having its corresponding parts designated by similar reference characters. The pump is referably driven fromv the engine crank sha by gearing, although it may be handoperated as shown in Figures 1 and 2. p At each reciprocation of the piston 4 oil is injected through' the pipe 25 into a chamber 26, see Fig. 7, which is in effect a pump barrel or cylinder, because within it a piston 27 is located which at each injection o oil through the pi e 25 is pressed toward the opposite end o the chamber, compressing a spring 28 and uncovering an oil port 29 through which the oil enters the interior of the reservoir 22, and asthe oil pump of the engine makes its back stroke, the action of the spring 28, causes the piston 27 to make its .return movement into substantiall the position shown in Fig. 7. The vpiston 27 is attached to a piston rod 30, which is pivoted at 31 to a link 32, which in turn is plvoted to a bellcrank lever 33, which is pivoted as at 34 to a xed bracket 35. The lever has on its other end a pivoted pawl 36. 37 is what I term a pan valve, because it is made in the general form of a dish or pan, the walls 38 whereof extending upwardly, terminate'in an annular upper edge upon which are located equally spaced series of equally spaced ratchet teeth, with which teeth the pawl 36 engages.\ Between each series of 'ratchet teeth is a smooth or toothless section 39 on the upper edge of the pan valve and in the wall of the pamvalve at a suitable distance from its bottom, as shown best in Figs. 5 and 10, is an opening 40, and somewhat above it and .likewise in the wall of the pan valve is a series of openings 41. As shown in Fig. 5, in the same horizontal plane as the o ening 40 is a seriesV of tubes 42, which lead, respectively, to the parts which are to be lubricated, one of such parts being illustrated as a bearing 42, The openings 41 are preferably equal in number and spacing with the tubes 42.

The openings 41 connect with a pipe 43 which leads back to the oil pump of the engine or to the reservoir therefor. In the center of the pan valve there isan upwardly presented boss 44, which acts as a bearing or than that of the sim ler form of apparatus first described and 1s as follows:

When not in operation the pointer 24, the

same as in the instance of the simpler apparatus, will be left on the indicator plate 24a ata neutral point between two of the indicia,

in which Iposition the arm 45 on the shaft 23 will be resting against the pin 46. When the parts are in this position the oil pump of the engine will at each of its reciprocations inject oil through the pipe 25-which will actuate the piston 27, which through the train of connecting devices will in turn actuate the pawl 36; but inasmuch as at this time the pawl is on one of the smooth toothless sections of the upper edge of the pan valve, there will be nothing but an idle back and forth movement of it, and the oil injected into the pan valve will flow back again through that one of the openings 41 in the pan valve as is then in registration with the return ipe 43, to the engine pump or reservoir. n other words, the entire apparatus will be idle except for the stated Howing of oil into and out of the reservoir 22.

When, however, the operator desires to lubricate any part he will move the pointer 24 to that one of the indicia 21 as designates the art to be lubricated, and this movement of t e pointer 24 will bring the arm 45 in contact with the pin 46 and rotate the pan valve in such manner that an opening 40 will be brought near a tube 42 which 'leads to the part to be lubricated and, 'at the same time, some ofthe teeth on the valve into active relationship to the pawl 36, so that oil will pass from the pan valve to such-part until the pawl has made as many forward movements as will coincide with the number of ratchet teeth in the series with which it is then in registration, and when the pawl has reached the end of that particular series of teeth, it will passupon the smooth adjoining surface 39 and there will then be no further rotation of the pan valve, but by that time the opening 40 therein will have passed away from the oiling tube 42 with which it has just been in registration and the further supply of oil thereto will cease, and it will be noted that because the openings 41 are preferably equal in number and spacing with the tubes 42,

that by the time the operation of the pawl has f I l which oil has just been sup lied, will have turn of the pan valve to primary position by handat the termination of each lubricating operation. -I prefer the construction shown and'described, because if present the pulsations of the oil pump of the engine automatically perform all the requisite operations, thus avoiding necessity for watchfulness and care on the part of the operator. 4

The operator lwill thereupon move the pointer to such other of the indicia as designate the other parts which he desires to lubricate and the above described operation will then be repeated.

It will be obvious to those who are familiar with such matters that the two apparatus which I have herein described and illustrated are two forms only of many inwhch my invention may be embodied, and that the details of construction may be changed without departing from the essentials of the invention. As an example of such vmcdilication, instead of'the valve plate 15 shown in Figs. 1 and 4 having a radial line of openings 17 therein, theremay be a single opening as shown. at 40 in Figs. 5 and 8. If so, the

tubes 18 must be arranged upon a concentric circle, so that the single hole in the valve plate will engage with them during the rotation of the plate. I prefer, however, for the simpler apparatus, the constructionshown in Figs. 1 and 4, because it will then be possible to provide additional oiling tubes l18, should the same be desired, and also it will be possible to have any two or more of the holes ,17 regis- ,ter with the oil tubes connecting with vtwo or more similar parts,- as,for instance, with the four springs, or with the two king pins, and the like. I therefore do not limit myself to the detailsnor to the particular embodiments of the invention herein described and illusbricant, to close said va ve.
