Specification of Letters Patent.
Patented Sept. 7, 1915.
Application filed. March 2, 1915. Serial No. 11,514.
To all whom it may concern:
Be it known that I, WILLIAM W. Conny, a citizen of the United States, residing at Hartford, in thecounty of Hartford and State of Connecticut, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.
This invention relates to lubricators, the primary object of the invention being to provide means of this character which is simple in construction, effective in action and by which an adequate supply of lubricant to the part to be lubricated can be maintained. The invention involves other features of novelty and advantage which with'the foregoing will be stated at length in the following description, wherein T will set forth in detail that one of the several convenient forms of embodiment of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. This showing has been provided to enable those skilled in the art to practice the invention. 7 I do not restrict myself to such disclosure; 1 may dopart therefrom in several respects within the scope of the invention defined by the claims following said description.
Referring to said drawings: Figure 1 is a side elevation partly in section of a metal 1 working machine provided with a lubricator constructed in accordance with my invention, the intermediate portion of the machine being broken away and the ends brought together. Fig. 2 is a top plan view of the same, parts being also in section. Fig. 3 is a side elevation of a duct constituting part of i the lubricator, and, Fig. 4 is a transverse section on the line l4l: of Fig. 1, looking in the direction of the arrow, this particular view being on a larger scale than the three preceding views. 7
Like characters refer to like parts throughout the several figures.
A lubricator comprising my invention can be utilized with advantage in many different connections; for instance and as shown it may be incorporated in or form part of a metal working machine. Inthis particular employment it can be utilized for supplying lubricant to a member on or forming part of a movable carriage. It is inconsequential what the character of movement be. In Figs. 1 and 2 the metal working machine is intended for boring work with the aid of a drill, the drill being sustained by a carriage 1n the nature'of a slide. There is a lubricator now in use involving a duct or conductor consisting of telescopic sections, one of which is connected with a carriage. In this old conductor there is no provision for securing a balance of the lubricant, the consequence being that the pressure of the lubricant is directed against the carriage which has to work against said pressure which is a matter of disadvantage. In addition to this accidents have been known to occur with this old type of duct or conductor. I provide a construction wherein there is a balanced supply member from which the lubricant, of whatever nature the same may be is led or supplied to the traveling carriage whether the movement ofthe latter be a slidable, oscillatory or rotary one, the nature of movement of the carriage not being material. As will be inferred'the lubricant may be of any suitable kind, for example oil or soda Water, these being merely two of several illustrations. While the lubricator as I have termed my improvement is of especial utility when employed in connection with a traveling carriage, it may be used with advantage when the part to be lubricated is stationary.
Referring now to Figs. 1 and 2 the numeral 2 denotes the base or bed of a metal working machine which has ways for supporting for reciprocation the carriage or slide .3, furnished with a drill 4, secured in the drill holder 5 by means for instance of a screwv 6, the drill holder 5 having a journal portion 7 supported for oscillation in the bearing 8 rising from the slide 3. In a machine such as shown the lubricant is to be supplied at thecutting zone, the drill 4 having a longitudinally extending channel 9 for the passage of the oil or other lubricant to the cutting portion or portions of the drill, the latter being in communication with a pipe as-lO which receives its supply of lubricant as will hereinafter appear. It is'quite common to supply lubricant through a drill. by means of a pipe 10 orits equivalent, for which reason these details are not further described, although it should be noted that the pipe 10 has a connection with "the carriage 3; for example its inner terminal may be tapped into the upstanding be'aringS of 10 to the drill 4:.
I To convey the lubricantto the pipe I :provide a duct or conductor such as that denoted-in ageneral way by 11 said duct'or conductor 11 being supplied with oil under pressure as from the pump 12 mountedon the bed 2 and delivering it in turn to the ;-pipe, 10. Theduct or conductor asillus- 1 trated comprises'the main element 12 shown as stationaryand in the form of a tube or pipe, the auxiliary supply member 13 being also in the form of a pipebut of greater diameter and surrounding the mainpipe or supply member 12 which latter as shown is connected atone end as by means of the pipe connection 14 with the deliverysideof the pump-12". ,It will, therefore, be understood that the oil is initially supplied into the main'itube or pipe 12 which as illustrated is practicallycoextensivefwith the base or bed 2. will be clear there is a space between the outer surface'of the main supply member or 'pipe12 and the inner wall of the auxiliary 'or movable supply member 13 and into thisspace' lubricant can flow from the pipe 12 for example by way of the port or perforation 15in said stationary or main pipe 12," the ends of the auxiliary or movable pipe 1 3.bein g closed by stufling boxes as 16which prevent the escape of oil from the ends of saidouter or movable pipe 13, which I might note at thistime has what are known as stations'from which lubricant can be taken. I
shouldstate that'the object'of providing several stations in or on the traveling or movablelubricant supply member 13 is to insure supply of the lubricantto the carriage 3 in the different adjustments thereof.
. Therejmay be cases where I should provide for taking away the oil'fromthe member 13 or; its equivalent at but a single place. By
providing several places, however, I provide means for readily conforming to the posi- By'providing the plurality of stations or discharge points I. insure proper supply of lubricant under the conditions mentioned. The parts are so proportioned of course, that the port 15 will never be uncovered by' the movable supply member 13. In Fig'fil the carriage 3 is shown at almost its extreme movement totheright, the closed left end of the part 13, however, not uncovering the (port. On the extreme movement of the car ri'age3 toward the left in said Fig. 1 the. closed right end of the pipe 13 will not cross 'theport 15. It will be clear'that lubricant is supplied to the "conductor 11 underpressure, thegoil initially, by way of the pipe 141 entering "the inner pipe 112 and passing through the port 15 into the space or interval between said pipe 12 and companion pipe 13.
The lubricant flows oppositely in the pipe 13, its pressure being directed evenly or equally against the two closed ends of the pipe 13,the consequence being that the latter is balanced as is also the carriage 3 which as will hereinafter be pointed out receives thelubricant from the pipe 13 by way of the pipe 10 through any one of several connections'with which the pipe 10 is adapted for interchangeable connection. There is, therefore, no resistance offered by the lubricant to the movement of the carrier 3. The outer end of the pipe 12 is provided with the usual relief valve 17 and overflow device 18, both quite common, the relief valve opening when the pressure of the oil exceeds a certain amount and the oil thus relieved passing into thepar 18 afterthe customary fashion.
The movable balanced supply member 13 has three discharge stations each denoted in a general way by 19 all alike and one shown in detail in Fig. 4. In Figs. 1 and 2 the pipe 10 is connected with the outermost station 19. Each of the stations 19 comprises a sleeve 20 fitted around the pipe 13 in a liquid tight manner, the stations as will be clear being disposed longitudinally of the pipe 13 at suitable points. From each sleeve the tubular extension or boss 21 extends, the opening of the boss 21 being in register with aport or hole 22 in the pipe 13. The tubular extensionsi21 have tapped holes 23 and 24 at the outer end thereof which intersect the passages of the respective tubular extensions, the tapped holes of the respective stations being as shown at right angles to each other, the holes 23 being approximately horizontally disposed and the holes 2 L vertically disposed. The holes 23 and 24 are adapted to receive interchangeably the-tubular extensions 25' of the unions 26, the
In the construction shown the oil or other lubricant is supplied by the pump 12 to the pipe 12 and from thence to the space or chamber between said pipe 12 and pipe 13 flowing from said space through the particular station (19) in use and thence by the pipe 10 to the drill, the lubricant being balanced before the slide is reached so that the pressure of the lubricant has no disturbing effect upon the carriage.
What I claim is:
1. A lubricator comprising a main pipe, an auxiliary pipe surrounding the main pipe and slidable thereon, the ends oi the auxiliary pipe being closed, the two pipes being separated and the main pipe having a port in communication with the space between the pipes, one of said pipes having an inlet and the other having an outlet.
2. A lubricator comprising a main pipe, an auxiliary pipe surrounding and slidable on the main pipe, the two being separated to provide a lubricant receiving space, the main pipe having a port opening into said space and the auxiliary pipe being closed at opposite sides of the port, means for supplying lubricant to the main pipe, and means for delivering lubricant from the auxiliary pipe.
3. A lubricator comprising a main pipe, an auxiliary pipe surrounding and slidable on the main pipe, the two being separated to provide a lubricant receiving space, the main pipe having a port opening into said space and the auxiliary pipe being closed at opposite sides of the port, means for supsure to said slide, comprising means for balancing said pressure before the lubri- V cant reaches the slide.
6. The combination of a movable element, a balanced lubricant supplying member in communication with and movable with said movable element, and means for supplying lubricant to said lubricant supplying member.
7. The combination of a movable element,
whereby the second pipe and movable element can move together, and a pump for supplying lubricant to the first pipe.
In testimony whereof I my signature in presenceof two witnesses.
