To'aZZ whom it may concern.'

Be it known that 1,0110 BERGER, a citizen of the United States', and a resident of New York, borough of Manhattan, in the county of New York and State of New York, have made and invented certain new and useful, lmprovements in Lubricators for Elevator-Guides, of which the following is a specification. l

u My invention relates to lubricating devices for -applying and. more particularly to. lubricating devices of the eneral type disclosed in Letters Patent o. 1,007,422 granted to me upon the 31st day of October, 11911.wherein a lubricant is applied to the guides 4by means of a wi Ver moving lin contact-therewith, and whic wiper is supplied with oil from an oil well. through or by means of a tubular oil feeding member containing a wick; and, among the objects ofmy invention are to provide `a having oil applying means separate from the wiper; to provide a lubricatin- .device in which the upper end of the oil we l is open,as distinguished from those covered by elements of the oil applying means; to provide a lu" bricating device in which the quantitylor amount of oil supplied to the guidesmay be easily adjusted to suit the necessities of any particular case; to vice which will be sim le in form, and which may be readily 'and c eaply manufactured; and to provide such other and further -improvenients in and relating to lubricating devices for elevator guides as are hereinafter more specifically referred to.

Withthe objects of invention above onul merated in view, myI invention consists in the improved -lubiricating device for elevator guides illustrated in the accompanying drawin and hereinafter described and claimed, an in such variations and modifications thereof as .will be obvious to those skilled in the art lto which my invention relates.

In the drawing accompanying-and forming'a part 'of this application and wherein the preferred embodiment of my invention is illustrated: Figure 1 is a view showing a section of my improved lubricating device taken upon a vertical planeindlcated by the line 1-1, Fig. 2, and illustrating how ,the same may be secured to an element of .the elevator with which it is used; Fig. 2 is a View showing my improved lubricating deoil to elevator guides,`

lubricatingl device rovide a lubricating de# viee in plan.; 'Fig'. 3, isa view showing a section taken vupon a transverse horizontal plane indicated by the line 3 3, Fig. 1,

looking down; Fig. et is a view showing a,

section taken upon a 'vertical plane indicated by the line 4 4., Fig, 3; Fig-5 is av fragmentary view illustrating a modified form of one ofthe elements of my device; and Fig. .6 is a view showing the clamping and-support1ng means for attaching the lubricatoi` to an elevato1.-Y

Referring to the drawing the reference numeral 8f designates'a-'portion of a vertically'extending elevator portion of an elevator, to w is secured andwithin which a springI 11 is located, which spring acts to '.force ajshoe 12 toward and. keep it in contact `with `theguide, all as is common in 'elevator structures and to which" features my "invention 1n no way relates. y

My improved lubricating device will be supported from the elevator so as tov travel therewith by means of any'suit'able and appropriate bracket or equivalent supporting means, the vbracket `or support illustrated" guide, and 9 a ich a barrel 10` comprising' an lupwardly extending bar "13 the lower end of which rests upon and is secured to two clips 14 the lower ends of which cli-ps are curved to embracethebar-v rel 10, and the upper end of which bar is bent downward and serves'as the immediate support for' my im roved lubricatingdevice. My improved l'u ricating device'comprises a reservoir 15 adapted. to contain .a consid erabl'e quantity `of'oi'l as indicated in thev drawing, and which oil reservoir /is shown as rectangular incross-section, although the particular form or shape of the oil reservoir isy of secondary importance and is not in'- -volved in my invention. The `oil reservoir is adaptedto -support a. swab 16 of absorbent material and awiper '17 also of absorbentmaterial, said elements being independent of one another and spaced a' arti as shown. rlhe swab is kept saturate or moistened with oil, and the purpose thereof is to 'l lubricant to the elevator guide with it moves in contact', while the wiper ."ieives,N

t0 distribute the lubricant uniformly over the guides, and to scrape off excess lubricant` and dirt should any collect upon the gui e.

The swab 16 and wiper 17 are shown as located within two recessed extending portions or extensions 18, 19 having upwardly extending peripheral Aor side walls as shown,

. and the bottom walls of which extensions are provided each with a slot adapted to receive an elevator guide as illustrated in the .drawing The upper: of these extensions is shown as formed integrally with the wall of theoil reservoirgl, whilev the lower is shownl as formed se arate from the reservoir andas secured tA ereto by a screw 20.l Either or bothof saidexten'sions may however, obviously, be formed' integrally with Athe'reservoir 15,701' either or both of theml may -be formed separate therefrom and secured thereto in any way. l. I

The extension 1 8 4is preferably provided withanv upwardly projecting wall or ledge 2l, of less height thanvthe side walls of and extending around thev 'slot formed in the bottom wall of said extension, wherebyl an oil retaining spaceorpocketfis rovided in the .lower portionof said extenslon. There is thusa considerable 'quantity'fof oil present immediately beneath the swab 16 when the lubricator is in us whereby the swabis kept saturated wit 'oil or suiciently moist' to secureV a proper supply of oil to the cle-l 4vatorvguide, as .it will be understood that a portion of the'swab extends downward and into the oil as best shown in Figkft. A block of felt 22 is also preferably provided with which the wiper is in contact, as shown, which block serves as an additional means for keepin the swab a saturatedicondi tion or su ciently moistened withoil to secure1 adequate lubrication ofA the elevator 'I he swababove referred to will obviously be of alform appropriate to apply oil to the particular form of elevator guide .to be 111-. ricated,. and Athe form of' my Invention illustrated in the drawing shows two such swabs arranged to apply 011 to opposite faces of an elevator guide. The swabs are shown as resting upon the upper end ofthe ledgev 21 and blocks of felt 22', andas held in place by plates 23 made preferably of indurated fiber, through Whic vbolts 24'ex`tend. The wiper 17 is also obviously of vsucha formas to contact with and wipe the surface or surfaces of the elevator ide to be lubricated, asA willbe understoo and is held 1n lace Within the extension 19 Vb means of p ate's 25, also preferably of in lurated liber, and

Oil is supplied to the swab 16 through or by means of an oil feedin member comprising a tube within whic an absorbent material is contained, one end of which tube 'depends into, the oil within the reservoir 15 and the other end of which extends to and vterminates adjacent the swab, so that oil will pass along the absorbent material' and through thetube and to the swab; the absorbent vmaterial being preferably in the form of a wick as shown in the drawing, and the lower end thereofextending into the oil receptacleor pocket provided in the lower portion of the extension 18.

The tubular member above referred to is shown as Uv-shaped in form and as having a leg 28 depending into the oil-reservoir, and a second leg 29 extending through a hole in the bottom wall ofthe extension 19 and terminating adjacent the swab 16. The upper end of this oil 'feeding'member thus lies above lthe level of the oil in the oil reservoir, and the rends of the absorbent member or wick 30 thereof extend beyond then .lower ends of the legs, and into the oilv in the oil reservoir', and .intov the oil retaining space or pocket formed in the lower portion of the extension 18by` the .'ledge'21, as hereinbe- .fore explained. The oil feeding member is referablyprovided Witha spring 31, the ree upper end Of-W'hich may be pressed against the wick, by means of. a screw 32,

to thereby regulate .the quantity of oil pass ing along the wick to the swab.

My improved lubricating device is shown as provided with two separate oil feeding members, inorder to secure a more uniform and satisfactory su ply of oil to the swabs 16, although it wil be understood that a single oilfeeding member will supply oil to vthe oil retaining pocket at the lower end of the extension 18 and consequently, to

both the swabs 16.

While I have shown the' oil feeding mem bers as comprising each a single tube with a single wick therein, -I prefer to make the oil feeding members in the manner illustrated in Fig. 5 whereinthe same is shown as made up of a plurality of separate tubes 33, each of which contains a wick 34, land which tubes collectively form a single oil feeding member equivalent in function to one of the two oil feeding members with which my dcvice isshown as provided in the other iigures of the drawing With this form of oil feeding member a closer and more satisfactory control of thegsupply of oil may be secured; zas, if the supply is insuliicient an additional tube may be added, while if the supply i's too profuse a tube may be removed; it being understood that a plurality of these .separate tubes will benecessary in order to secure an adequate supply of oil to the swabs in all cases, and 4that such supply may be increased or decreased by small moaned ot and located above said swab and carried' by said reservoir; a tubular` lll-shaped oil :feeding memberfthenppe'r end of which lies above the level ot oil in said reservoir and one leg of which depends thereinto, and the other leg of which member terminates adjacent said swab; and a wick et absorbent material within said oil feeding member and through which oil is supplied to said' swab. l
