LUBRICATOR.

No. 820,821. v

To all whont 'llt may concern Be itknown that l, JOHANNES TH. PannasEN, a citizen of the United States 0f America,

residing at Woodside, in the county of Queens,

city and State of New York, have invented an Improvement in Lubricators, of which the following is a specification.

My invention relates particularly to the class of f orce-feed or power-actuated oil-feeding devices or lubricators especially adapted to supplying lubricating-oil to the machinery of motor-vehicles,motor-boats, &c.; and the object of my invention is to providel a lubricator of simple construction and in which springs', check-valves, and other small and uncertain parts that are liable to get out of order are dispensedwith, and also to provide in the one structure avdevice which while I normally actuated by the power of the machinery being lubricated may also be manually operated, if desired, to supply oil previous to starting up the machinery and without disturbing the connections or devices for mechanically o erating the lubricator.

My improve lubricating device comprises,

" essentially, a revoluble shaft, a reciprocating tons in one position they draw the oil from the said sight-feed and in the other position force the said quantities of oil to the parts of the machinery to be lubricated. The pistons of the series are moved longitudinally by a rocker, which at the same time is actuated by an engaging revoluble member to reci rocate the series of pistons in ways provide therefor. These parts are contained in a receptacle holding the lubricating-oil and from .which the oil is drawn and forced to the sightfeed and from which the oil received is forced to the machinery and parts being lubricated.

The guides of the reciprocating series of pistons are provided with ports at each side and the difference in length between the pistons and their cylinders and the diameter of the parts regulate the quantity of oil moved Specification of Letters Patent. v

by each piston at each stroke.

Patented May 15,1906.

The sight-` 5 feed structure is provided with a regulatable oil-feed controlling the quantity of oill delivered to be forced to the machinery `and with means for returning the' surplus thereof to the oil-receptacle. devices and discharge-pipes agree with the number of places to be lubricated.

In the drawings, Figure l is a vertical lon- The number of feed 6o gitudinal section and partial elevation of the devices of my lmprovement. Fig. 2 is a ver- 65 tical cross-section at right angles to Fig. 1. Fig. 3 is a plan of the parts within the oil-receptacle with the cover broken o en and a horizontal section through the regu atable oilfeed devices, an end view of the slide, the 7o slotted rocker-shaft, and an elevation and partial section of the piston, together with a section of the slotted rocker-arm. Fig. 4 is /an elevation of the regulatable sight-feed device. through t e upper portion of the sight-feed. and through the regulating devices and in opposite positions,the same being of exagj gerated size for clearnes's.` Fig. 7 is an end elevation of the slide, showing the bearings 8o for the slotted rocker-shaft. Fig. 8 is a sectional end View of the slide, the slotted rockershaft, and an elevation and partial section of the piston, together with a sectiony of the slotted rocker-arm. Fig. 9 is a plan of the 85 v slotted rocker-arm. Fig. `10 is an elevation of thesame; and Fig. 1l is a sectional plan at the dotted line :n shown in Figs. 1 and 2.

Fi s. 5 and 6 are sectional plans 75 The receptacle for lubricating material is usually composed of the bottom a, back a', 9o

front a2, and ends a3, and formed therewith are lugs 4 for attaching the same to a suitable support.

b represents the cover, preferably with a groove in the under surface, whereby the 95.

cover fits down over the upper edge of the body, the cover being held tothe body by the screws 2 at the corners. one end is rovided with an aperture interiorly threa ed to receivethe filling-nozzle b', which is screwed thereto, and the aperture o'f the nozzle is interiorly'threaded to receivey The cover at IOO the threaded plug or stopper b2, and I provide Y..

a sight-tube b3 at the front of the oil-receptacle to indicatethe level of the oil therein.

c represents a shaft, and c a wheel or sprocket on the outer end of the same, said shaft passing through a suitable bearingsleeve c2, secured, preferably, to the back a of the oil-receptacle and held in position by a nut 3 and provided with a packing 4. A belt or chain 5 passes around the wheel or sprocket c for rotating Vthe shaft, power and movement being communicated by the mechanism that the device of my improvement is employed to lubricate, and while I have shown in the drawings awheel and belt it is obvious that a sprocket and chain may be employed in their place.

y On the inner end of the shaft c-that is, Within the oil vessel or receptacle-there is a worm c3, and passing through the oil-receptacle vertically there is a shaft d. This shaft passes through the cover in an opening provided therein for the shaft, the bearing at the lower end being a bracket 8, secured as hereinafter described. Upon this vertical shaft d is a loose worm-wheel d', With which the worm c3 is in mesh. Around the vertical shaft d and secured thereto is a ratchet'dz, by its hub 6 above the ratchet, pinned to the shaft d, and the bearing-bracket 8, coming below the loose worm-wheel d. These parts are held in position on the shaft. Up'on this loose worm-wheel d there is a spring-held pawl d3, mounted upon a stud 7, secured to the loose worm-wheel, the said pawl b earing and meshing with the teeth of the ratchet d2.- At the lower end of the shaft d and secured thereto in any desired manner below the bracket-bearing 8 is a slotted crank-arm e.

I employ a frame secured within the oil receptacle or vessel and to the bottom thereof, which frame comprises the parallel side members ff and cross-connecting members f near the bottom of the vessel and coverplates f2 upon the upper edges of the side members f and between which cover-plates and the si e members are formed slideways for a reciprocating frame of cylinders, hereinafter described. In these side members f f are series of ports at predetermined places. (See especially Figs. 2 and 11.) In the lefthand side member f, Fig. 2, there are a series of inlet-ports 9, four m number, agreein with the initial position of pistons hereina ter described, and shown in Figs. 1, 2, and 1 1, and through which ports 9 the oil from the reservoir enters. In this same side there are a series of intermediate ports 1( which rise and communicate with the pipes 11. These ports 10 are also four in number. In the opposite or right-hand side member f, Fig. 2, there are series of intake-ports 12 directly opposite the ports 9 and which communicate with ipes 13, rising from the right-hand side memgerf, and there are other ports, four in number, opposite to the ports 9 and which may be desi nated asdischarge-ports 14, which are in ine with pipes 15, that extend to the parts to be lubricated, and it is to be remarked that while I have shown four series of port-s in each of the side members there may be any number of ports in the series, as the ports of the series must in all cases agree in the lubricating device of my improvement with the number of places to which the oil is forced for lubricating the machinery. The bracket 8,hereinbefore described, is to be secured to or formed in one with the coverplate f2 at the right-hand side for support.

g represents a reciprocating frame of cylinders, each of which cylinders is centrally and longitudinally slotted in the u per surface g', being end bearings on the game g. This frame of cylinders is received between the right and left hand side members f f and between surfaces prepared thereon and the under surfaces of the cover-plates f2. I provide a rock-shaft h with trunnion ends in the bearings g, which rock-shaft is longitudinally slotted in the under surface, as appears from Figs. 1 and 2. This rock-shaft has a pin h secured thereto and projecting from the upper surface. This pin passes through the slot of the crank-arm e and is advantageously provided with a roller (shown in Figs. 1 and 2) contacting with the inner surface of the slot of said crank-arm. The slot in the said rock-shaft is indicated at 16. In the cylinders of the reciprocating frame g I place pistons i, which are shown as plain cylinders of metal each provided with a pin i', extending up through the slot of its cylinder and entering the slot 16 of the rock-shaft h.

The sight-feed devices for the oil and in which the movement thereof is visually indicated are shown as extending above and attached to the cover b. This is for convenience and compactness; ,but it is obvious that these sight-feed devices may be located anywhere in the line of pipes conveying .the oil. These sight-feed devices are alike, and similar parts therein carry the same letter of reference, and the description of one will suffice for all. In each of these, c represents the cylindrical glass section of the sight-feeding device, at the lower end of which is a metal annulus 7c', secured in an aperture of the cover preferably by overturning the lower edge and by the shoulder above the cover, while at the upper end there is an annulus k2.

In the lower part l represents a thimble centrally receiving the pipe A'13, the center of the thimble being made funnel shape for the discharge of the oil into the pi e 13. At the upper end there is also a thim le Z, which is o conical configuration centrally perforated. This thimble Z comes within the annulus k2 and extends above the same and is securely held in position by the nut Z2, which screws upon the outer surface of the same down to the upper end of the annulus k2.

m represents a curved pipe the lower end of which passes into the pipe 11, secured to the left hand of the side members f, Fig. 2, and the upper end of this curved pipe m passes up Within the sight-feed, `through the riorly and agrees in its taper with the conical interior of the thimble Z, and said valve'r is rovided with a central perforation 17 and a ateral perforation 18 and with a circumferential by-pass 19, the center of which is in the same horizontal plane with the centerv of the lateral openingel. This particular construction is amply illustrated in Figs. 1, 5, and 6, and. the horizontal plan through the by-pass 19 and lateral opening 18 agrees with.

the upper ends of the pipes m and' n, which are made inclined, the upper end of the valve v1^ being provided With a kerf for a screw-driver,

by which the Same may be turned, or any other suitable mechanical contrivance may be employed for turning the said valve and indicating its position.

In the operation of my improved liibricating device and after oil has been filled into the vessel or receptacle the rotation of the shaft c and its worm @"irotates the worinwlieel rl and by its pawl di* the ratchet Z2 and shaft d. The slotted crank-arm e turns with the shaft l and by its rotary 'movement' actu- -ates the pin Zi and slotted rock-shafti to impart reciprocatingr movement to the pistons i ofthe series, all of the pistons moving simultaneously .in'the same direction. F rom the peculiar eonstruetionof this'l slotted crankarm c and its relation to the slotted roekshaft h and with s ecial reference to F 2 and 3 it will be noticed that following the direction of rot-ation indicated by the arrow the further movement of said crank-arme cannot further swing the shaft Zz', because the same hasreached its extreme movement with thepistons. Consequentlythenexto eration will be to move the reciprocating amel of cylinders g along in the slidewayr provided therefor in the side members 1n this movement the piston-cylinders will go from the series of ports 9 on one side to the series of ports 10 on the same side and on the other side from the series of ports 14 to the series of ports 1 2, (see Fig. 1 1,) and after reaching this position the further movement of the said crank-arm e will be above and over the rockshaft Zz., swinging the saine fronrthe position shown in Fig. 2 to its opposite position and in so doing move the pistons i from the position shown in Fig. 2 to their opposite position. In the movement of the reciprocating frame of cylinders and pistons from the positions shown at the ports 9 to the position at the `pipe 13 to the ports 1() the oil drawn in at the ports Qwill be moved to the ports 10, and with the swinging ofthe rock-shaft Zzy and the moving of the pistons to the op )osite position (shown` iii Fig. 2) the oil will e forced into the ports '1"0 and pi es 11, and so into the pipes m and up into t ic sight-feeds, passing'either partlyT through the lateral opening-18 and by-pass 19, as in Fig. 5, or entirely by the by-pass 19, as in Fig. 6, or, if thevalve r is soset, the. entire amount of oil Will ass -bv-the openings 18 and 17 in the sighteed,"aiid soI b v the' o positie end o t ere With the return movement of the reciprocating frame of cylinders and pistons which will take place with the further movement of the slotted crank-shaft e on the opposite side of the position shownin Fig. 3, returning said parts to the osition shown in full lines, Fig. 3, after wliic i the further movement of said slotted crank-shaft to its position shown in Fig. 3 will swing the rock-shaft Zi, and move the pistons into the positionH shown-in yfull lines, Fig. 2, in which the oil drawn from the sight-feed devices will be forced through the pipes 15to the parts of the machinery to be lubricated. It is apparent that in this operation if the valve 1" is in the osition Fig. 6 all of the oil raised throng the pipe lm will go by the b v-pass and the )ipe n andy be returned to the receptacle, an( it.y is also obvious, referring to Fig. 5, that a part ofthe oil will goby the bhv-pass 18 and pipe n' and return to the receptacle, while the other part will go by the openings 18 17 throiigh the sight-feed into the pipe 13 to be forced for lubricating the machinery, and it will be also apparent that if the lateral opening 18 is in line with the pipe n the entire quantity of oil raised will pass by the openings 18 and to be forced to the machinery for lubricating.

I have shown in Fig. 3 the peripheriesof the nut Z2 and cap 0 as kniirled, so that the saine mayl be grasped and turned by the iingers in case it is essential to separate the oilfeed devices and cover from the oil-receptacle and other parts, in which movement the thiinbles Z and Z, being firmly eonneeted'by the pipes m and 1i, come awa-y with said pipes and the pipe 1B, leaving the. annulus Z" alone secured to the cover, 'and they may be replaced in the reverse manner. The movements herein described are continuously repeated so long as the machinery tobe lubricated is running, driving the belt or chain 5, and it is also obvious that Ythespeed at which ports tobe drawn into the: the pistons and be retained .ICO
