SPECIFICATION formingpart of Letters Patent No. 791,418, dated May 30, 1905.

Application filed April 13, 1904. Serial No. 202.941. I

To all whom it may concern.-

Be it known that I, WILLIAM A. HATGI-IER, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Lubricators; and I hereby declare the following. to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in lubricators, and pertains more especially to a lubricator comprising a lubricant-receiving receptacle provided at its lower end with several discharge-ducts arranged a suitable dis tance apart and in line laterally and means whereby the said ducts are successively supplied with grease or lubricant.

The primary object of this invention is to conveniently apply adequate power to the lubricant-feeding head or piston on top of the grease or lubricant within the aforesaid receptacle to adequately and positively feed lubricant from the said receptacle to each of the aforesaid ducts and to render the said receptacle chargeable with facility.

Another object is to construct a lubricator of the character indicated which is simple and durable in construction, conveniently operated, and reliable in its operation.

With these objects in view my invention consists in certain features of construction and combinations and arrangement of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation, largely in central section, of a lubricator embodying my invention and shows the lubricator connected with several lubricant-conducting pipes. Fig. 2 is a side elevation of the externally-screw-threaded gear-bearing shaft employed in actuating the lubricant-feeding piston or movable pressureexerting head of the lubricator and shows the said head ready to be removed upwardly from the lower end of the shaft. Fig. 3 is avertical section on line 3 3, Fig. 2, looking in the direction indicated by the arrow.

Fig. 1 is a top plan in section on line 4:4, Fig. 1. Fig. 5 is a top plan in section on line 5 5, Fig. 1.

Referring to the drawings, A indicates a vertically-arranged receptacle which is provided interiorly with a lubricant-receiving chamber a, which is circular in cross-section.

Within and centrally of the chamber a (see and centrally of the top of a horizontally-arranged box 13, which is integral with the receptacle A and arranged below the gear I). The box 13 afiords bearing to a correspondingly-arranged shaft O, which has also bearing in two boxes 14 and 19, which are formed integral with the receptacle A and arranged at and a suitable distance from opposite ends, respectively, ofthe central box 13.

The shaft B rests at its lower end upon the box 13 around the bearing 12, and the gear 6 is in mesh with the bevel-pinion 0, operatively mounted on the shaft O between the central box 13 and the end box 19, and the chamber a is enlarged downwardly, as at 15, between the said boxes and around the said shaft to accommodate the location of thesaid pinion.

The shaft O extends through the end boxes 14 and 19 and is operatively provided at the outer end of the box 19 with a hand-wheel O for turning the shaft. The receptacle A is provided at its upper end and exteriorly with screw threads engaged by corresponding screw-threads formed upon and interiorly of the depending annular flange d of a cap D, which closes the said receptacle. The cap D is provided at its under side and centrally with a depending bearing-forming cylindrical lug 16, which projects into and snugly but 12. By the construction hereinbefore described it will be observed that the lugs 12 and 16 afford lateral bearing to the shaft P.

The piston or head G is mounted upon the shaft B and has a hub 0r centrally-located sleeve 9 embracing the said shaft, which sleeve is provided interiorly with screw -threads engaging with screw -threads formed upon the shaft. The shaft B is screw threaded approximately its entire length. The head G fits snugly but easily within the chamber a and is movable, as will hereinafter appear, endwise of the said chamber. The head G is prevented from turning with the shaft B, so that the said head will descend or ascend, according as the shaft is turned in the one or the other direction.

The means employed for preventing turning of the head G with the shaft B (see Figs. 1 and 4) comprises, preferably, a metal strip 17, which is arranged vertically within and secured to the surrounding wall of the chamber rt. The member 17 extends the entire length of the path of the head G and engages with a recess 18, formed in the said head, and thereby prevents the said head from turning upon the shaft B during the rotation of the said shaft.

The shaftCis provided interiorly with apassage-way-forming bore 20, which extends longitudinally of the shaft from within the hand- Wheel-bearing end portion of the shaft to the outer end of the box 14, Where it is closed by an internally-screw-threaded cap a, which embraces the outer end of the said box and engages corresponding screw-threads formed upon and exteriorly of the said box. The shaft C is provided at the outer end of the box 19 with an external annular shoulder 22, which is overlapped by the inner end of a ring f, which loosely embraces the shaft C. The ring f is provided at its inner end with an internally-screw-threaded annular flange 23, engaging corresponding screw threads formed upon and exteriorly of the outer end portion of the box 19. It will be observed, therefore, that the cap a and the ring f prevent endwise displacement of the shaft (J.

The receptacle A is provided at its lower end and next below the shaft C with four downwardly-discharging ducts 24, 25, 26, and 27, arranged a suitable distance apart longitudinally of the said shaft and in line laterally, as shown in Fig. 1. The grease or lubricant supplied by my improved lubricator is forced from Within the chamber a to and through the ducts 24, 25, 26, and 27 into the tubes or pipes P employed in conducting lubricant to axles or bearings to be lubricated. As shown in Fig. 1, the ducts 25 and 26 are formed at the bottom of the central box 13 and the ducts 24 and 27 are formed at the bottom of the boxes 14 and 19, respectively.

The downward enlargement 15 of the chamber a. is in communication with the interior passage-way 20 of the shaft C through two ports 28, formed in the surrounding wall of the said passage-way at opposite sides, respectively, of the said shaft, as shown in Fig. 5. The chamber (I, is also enlarged downwardly around the shaft (J, as at 30, and the said downward enlargement 30 of the said chamber is in communication with the interior passage-way 20 of the shaft 0 through two ports 32, formed in the surrounding wall of the said passage-way at opposite sides, respectively, of the shaft. It will be observed that the interior passage-way 20 is continually in communication with the chamber (1/. The shaft U is provided also in the surrounding wall of its interior passage-way 20 with as many ports as there are discharge-ducts leading from the lubricator. The shaft U of the lubricator illustrated is provided, therefore, with four ports 34, 35, 36, and 37, adapted to register with the ducts 24, 25, 26, and 27, respectively. The ports 34, 35, 36, and 37 are arranged, therefore, at suitable intervals longitudinally of the shaft 0 and are spaced, furthermore, equidistantly circumferentially of the said shaft. The arrangement of the ports 34, 35, 36, and 37 relative to the ducts 24, 25, 26, and 27 is such that the ports 34, 35, 36, and 37 shall during the rotation of the shaft 0 successively communicate with the different ducts 24, 25, 26, and 27, respectively.

To facilitate the distribution of the lubricant within the passage-way 20, the ports 23 communicate with the said passage-way between the ports 36 and 37 and the ports 32 discharge into the said passage-way between the ports 34 and 35.

The operation of my improved lubricator is as follows: The shaft 0 is rotated. Power is transmitted from the shaft C to the shaft B through the medium of the pinion c and the gear 6. The receptacle (1. is charged with grease or lubricant (not shown) by removing the cap D and the head G, whereupon the head G is introduced into the chamber (6 and the cap Dis replaced. The head G is prevented from rotation with the shaft B, as hereinbefore described, so that the head G during the rotation of the shaft B will descend and exert pressure upon the grease or lubricant contained within the chamber (1/, and thereby force lubricant through the ports 28 and 32 into the interior passage-way 20 of the shaft C and thence into the ports 34, 35, 36, and 37. As already indicated, the ports 34, 35, 36, and 37 discharge successively during the rotation of the shaft C, and consequently lubricant is adequately, positively, and uniformly fed to the different ducts 24, 25, 26, and 27 during each complete rotation of the said shaft.

It will be observed that by the construction hereinbefore described the shaft B and the head G are free to be removed from the chamber aupon the removal of the cap D. The shaft B and its gear I) and the head G are together lifted from the chamber a when the said head has descended into its lowermost position within the said chamber.

The head G to facilitate its removal from the shaft B is divided centrally and longitudinally .of its sleeve 9 into halves or sections hinged together at the bottom and adjacent the joint between the said sections. Preferably each section of the head G is provided at its under side with cars 40, which are horizontally pivoted, as at 42,"to the ears of the other section of the said head. By this construction it will be observed that the sleeve g of the head G is when the said head is in the chamber (I held in operative engagement with the shaft B by the surrounding wall of the said chamber; but when the shaft B and head G are removed from the receptacle A, as shown in Fig. 2, the two sections of the head G are no longer held closed together by the said wall and tilt downwardly by gravity, so

as to laterally open the sleeve 9, and thereby become disengaged from the screw-threads of the shaft B and render the said head free to be lifted from the said shaft. In replacing the shaft B and head Gr within the receptacle A the shaft B is first placedin position with its gear 6 in mesh with the pinion c whereupon the chamber cr is charged with lubricant, and thereupon the head G is applied. The shaft B extends a suitable distance. above the upper end of the receptacle A and above the strip 17 and is preferably screw-threaded from its lower end upwardly to and above the said strip 17 to accommodate the placing of the head G with threads of the sleeve 9 in engagementwith threads on the shaft preparatory to the engagement of the recess 18 during the application of the said head with the aforesaid strip 17, and the head Ghaving been operatively mounted on the shaft B is adjusted circumferentially to bring its recess 18 opposite the upper end of the strip 17 and held in the required adjustment until the said recess during the lowering of the said head has engaged with the said strip 17 whereupon the cap D is applied. The central portion of the cap bulges upwardly, as shown in Fig. 1, to accommodate the extension of the shaft B the desired distance above the strip 17.
