Specification of Letters Tatntl To (111 whom. it may concern Be it known that we, Enwnv M. MAOKIE and James A. THOMPSON, citizens of the United States, residing at Chicago, Cool: county, Illinois, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.
Our invention relates to lubricators and has more particular reference and application to lubricators for rock-drills and the like and the object thereof is to provide suitable and efiicient means for supplying the lubricant (such as oil) in such a manner as to insure a proper supply and an economical use of the oil and also to insure freedom from dust, grit and the like with which the oil is liable to become impregnated under ordinary systems of lubrication.
According to our invention. as hereinafter described, we provide a. closed oil reservoir from which the oil is supplied, at the will of the operator, in certain predetermined amounts, or doses so to speak, the oil being measured out from the oil supply and delivered to the motive fluid connections running to the drill without at any time be oming exposed to the air or to theentrance of dust, grit, etc.
The various features of advantage and utility in our invention will be apparent from the description hereinafter given.
'In the drawing, Figure 1 is a front elevation of our lubricating device; Fig. 2 a central vertical section thereof; and Fig. 3 an elevation thereof with a portion of the same broken away to illustrate the plug valve in 7 cross section.
'Referring to the embodiment of our invention as illustrated in the drawings, the lubricating device comprises a body areasring 1 in whose upper endis formed a chamber 2 adapted to contain a' supply of oil. This oil chamber is arranged to be filled from the top through a filling opening which is normally closed by means of a screw plug or filling cap 3. By preference we employ in the filling opening a screen or strainers; so that in case the oil chamber or reservoir should be filled at the place of use 0 of the drill where the atmosphere is generally charged with an abundance of dust and grit, the oil may be thoroughly strained. This strainer is removable so that ft may be readily cleaned when necessary. I
The casing is provided toward itsl central portion with a transverse bore or opening which is truncated conical 1n the section Patented June 3, 191a.
shown in Fig. 2 and is arranged to form an inclined or conical seat for the plug valve One end of this plug valve is provided with an operatingstem 5 extending beyond the surface of the casing and provided with suitable means whereby the plug valve may be manually operated such as the handlepiece or star-wheel 6, clearly illustrated in Fig. 1. The larger end of the 'bore in the casing in which the plug valve operates is' closed by means of a screw plug or cup 7.
The oil reservoir or chamber is arranged to communicate with the valve seat by means of the bottom opening or port 8 which is in position to register with any one of the four pockets 9 formed in the surface of the plug valve. There are preferably four of these pockets and the same are herein shown as located ninety degrees apart. These pockets may be of a suitable capacity dependent upon the amount of oil which the operator desires to feed to the drill at any one time. The lower side of the valve seat at a point substantially one hundred and eighty degrees from the port 8 is provided with a port 10 which communicates with a passage 11 in the lower end of the casing which passage is adapted t communicate with the motive fluid, air on steam, which operates the drill; In the present instance this con- 'nection consists of a T 12 having one 'connection with said passage 11 and having its othertwo connections. communicating respectively with the source of motive fluid and with the machine or drill.
It will now he evident that as the pockets are presented to the port Sthe same are filled with oil and that whenthe same are presented Fo, that is, are in register with, the port and passage l0,'they are emptied of their contents into the passa-ge'll and into the T from which the oil is carried by the motive fluid to the working parts of the machine or drill. Referring in detail to Fig. 3 the pocket whichis uppermost is now filled'with oil and assumin that the valve has been moved in a clockwise direction, the next adjacent pocket on the right-hand side is likewisefull of oil while'f the remaining two pockets are empty, the lowermost pocket having just delivered its contents to the passages 10 and 11 and the other pocket having previously delivered its contents and being of indicating and holding line.
ready to receive an additional supply or dose of oil When the valve shall have been given another quarter turn. In this manner the oil is supplied at the will of the operator in amounts or doses of a predetermined size and moreover the arrangement is such that the oil is delivered direct from the oil reservoir to the machine or drill without being exposed at any time to the atmosphere or to the possible entrance of dust, grit, etc.
In order that the registering of any one of the pockets with the ports 8 and 10 may be determined and indicated to the operator and in order also that the valve may be held in any one of its four positions with a yielding pressure, we provide suitable means as for instance the spring-pressed latch pin 13 which is movable in a chamber or cylinder 14 in the star-wheel and is normally held projected against the surface of the casing by means of a coiled spring 15. This pin is adapted to 1'( glster with and to engage any one of four sockets 16 arranged on the side of the casing at points corresponding to the pockets 9 with the result that when the pin 13 isin anyone of the sockets one of the pocketsis in communication with the port and passage 8 while another one of them is in communication or register with the other port or passage 10. According to the construction shown in Fig. 2 the spring 15 bears at one end in the soeketed end of the pin 13 and at the other end against a screw plug 17 screwing into the bore or chamber 14: in the star-wheel.
The plug valve'i nay be held firmly seated with a yielding pressure in suitable manner but for this purpose we prefer to employ the pressure of the motive fluid which is supplied o the machine or drill and to this end we 'pro\ide the casing with a small branch passage 18 extending l'roin the passageor connection ll to the space 15) on the lefthand end of the plug valve (Fig. 2) so that the pressure of the against this end of K to hold the atter seated as described.
ln addition to its above described function the valve to correct position for the delivery or receiving of the oihthe latching device has another function, that of holding the plug valve 5 to,its seat when the pressure is oil the line or inotive fluid conduit to the rock drill or the like, or to assist such pressure when on the It is to be noted that the latch pin 13 is spring pressedtoward the left with the result that, the star hub being spring pressed in the opposite direction or to the right, the plug valve is likewise held with such yielding pressure in such latter direction, to press it upon its seat. Consequently, even when the pressure is not on the line, the plug valve is held tightly seated and the oil is thereby prevented f om escaping or leaking from the oil chamber and out between the valve and its seat.
It will be understood that our lubricating device may be attached at any point in the hose connection which supplies the motive fluid by using an ordinary standard pipe nipple and T.
We claim:
1. In a device of the class described, a easing containing a chamber for a supply of the lubricant and having a valve chamber therebelow and communicating therewith, a rotatable plug valve arranged in said valve chamber provided With a plurality of pockets each adapted in one position, to receive the lubricant and in another position to deliver the same and means revolnble with said plug and extending parallel therewith for holding the plug to its seat and in different correct positions corresponding with the registry of the pockets and ports, said plug being tapered and said means engageable with said casing and acting in the direction opposed to the taper of said plug.
2. In a device of the class described, a casing containing a chamber for a supply of the lubricant and having a valve chamber below and at right angles thereto and comn'iunicating therewith, a tapered rotatable plug valve arranged in said chamber and ewheel and its i cry, sa1d plng stem proyectlng l outer wall of the casing having a plurality motive l'luid thus bearing 5 the plug valve will serve i" operating means for having a plurality of pockets in its periphvalve having an operating beyond the chamber, the
