LUBRKCA'EIHG iifEiiRrrTUS.

invented new and useful improvements in Lubricating Apparatus Of'WillCll the "1- lo'wing is a specification My invention relates to apparatus for lubricating the guide rails of elevating machiner or the like and particularly to that type supplying lubricating fluid, at prccletermined points in the elevator travel, to suitable lubricant distributers of *lubricw tors which are located on the elevator carriage and bear against the exposed faces of the guides to be lubricated.

One object of the invention is to produce an ,appzrjistus oi the aforesaid type which adapts i self to the elevator side play in. such a manner as to furnish at each actuation of the apparatus a substantially uniform quantity of lubricant to the lubricators, thereby eliminating the disadvantageous feature in known apparatus of this type of supplying a continuously varying quantity of tiuicl more or less dependent upon the lateral t isplacement of the elevator with respect to the guides.

The invention further contemplates an apparatus whoseparts may be readily adjusted to supply the exact amount of lubricating fluid requisite for the particular elevator; whose parts are so constructed and arranged with relation to each other as to reduce to a minimum sudden jars and pounding lue to the operation of the apparatus; and further a lubricating appa futus characterized by its rigidity in'construction, by its simplicity in operation and parts, and by its reliability for service with a miniiriuiu of attention.

In addition to the above desirable features other advantages of my apparatus will pear lz-y reference to the following described drawings which are merely illustrative of one 1" rm of my invention, wherein:

This reservoir carries suitable luil'lCilE'iij distributors or lubr cators 3, similar to the distributers shown and illustrated in my former Patent No. 821,072., issued May 22, 1906, these distributers being suitably fired to the reservoir as by uprights 4e bolted to suitable lugs 5 on the bottom of the res ervoir 1 (Fig. 6). It is to he understood that a lubricant is supplied to theexposed faces of an levator guide rail (not shown) throw, ese distributers 3 and a collecting 5 cone 6, preferably incased in a Z? of glass, is provided with ducts lea lg to and supplying the various distrihuters 3, all in a similar manner to e disclosure in above mentioned goutent. go

slotted to straddle the disk 10. The disk is carried by a shaft suitably journaled in hang-- erslit extending downwardly into the tank no i from the collecting pan. To the shaft is also fixed u. pinion 12 which meshes with a those carried by the elevator or car.

segmental gear 13mounted on shaft l t, this shaft being journaled at one end in an upright from the collecting pan 8 and at the other end in a bracket 15 fixed as shown to the side of the reservoir. The segment extends downwardly through a slot in the bottom of the collecting pan into meshing gear with the pinion 12 for actuating the disk 10. The bracket 15 extends toward the left bey'ond the reservoir and near the end is pivoted the'reto a bell crank 16. One end of this lever carries a buffer or bumper wheel 17, preferably of elastic material such for instance rubber, and to the other end of the bell crank lever is pivoted a connecting link 18 connecting the lever to a crank arm 19,

fixed to the shaft 1 1; so that by rocking the lever 16 power is transmitted through con necting link 18 and crank arm 19 to the 20 rock shaft 14 which actuates the segmental gear 13 to revolve the disk 10 to supply oil to the collecting pan. The bell crank lever 16 has therein a slot through which projects a stop 20 fixed to the bracket 15, this stop 20 serving to limit the rocking movement of the bell crank lever 16 in either direction of rocking movement by engaging opposite ends of the slot. may be provided and screwed into the lever 16 so as to project within the opposite ends of said; slot for the purpose of adjusting the maximum rocking movement in either direction. The bell crank lever 16 is also provided with a cut-out portion 22 into which projects the free end of a spring 9.8,the other end of this being fixed to the bracket 15 in any suitable manner, as by means of a screw. The purpose of this spring 23 is to serve as a cushion means for the lever mechanism 4 when the mechanism is being actuated, as

shown .in Fig. 1, and also as a retractile means to bring the leverage system back to the normal idle position indicated in Fig. 7. All the parts heretofore described are F or actuating the disk 10 through the leverage gearing system above described suitable projections or bumpers are stationed at intervals along the elevator travel in the path of the bumper wheel 17. One of these bumpers 2% is shown in the drawing and is carried by aportion 25 of the guide rail frame work. As Qhe elevator passes this bumper the bumper wheel 17 comes into engagement therewith and the lever 16 is thereby caused to swing in a direction depending upon the direction of the elevator travel, thereby actuating the transmission gearing described above to actuate the disk 10 to supply lubri- 0 cant to the collecting pant, thence from the collecting pan through the conduits 9 to the collecting cone 6 and from there to the var-i ous distributers.

It is known that side play is always pres- 5 cut in an elevator due to either defects in Suitable set screws 21,

noeaeas 111g movement being dependent on the relative lateral positions of the budcr 24 and the bumper wheel. 17 at the time the elevator is passing. Such variations in rocking move ment would of course result in unequal quantities of lubricant being supplied by the disk 10 to the pan 8, as the quantity supplied at each actuation is more or less dependent upon the number of revolutions made by the disk, and in order to eliminate this disadvantageous feature which may be caused by the side play of the elevator I propose to mount the bumper 24 yieldingly on the guide rail frame work for lateral movement relative thereto and to make this latei al movement great enough to take care of the side play of the elevator. In this manner the lever 16 may be given itsmaximum rocking movement at each actuation of the apparatus regardless of the variations in the side play. To this end I fix to the portion 25 of the guide rail frame a suitable spring 26 preterably of the form shown, this spring being conveniently secured at its middle point by a set screw 27; and the bumper :24 is provided in its middle portion with a transverse slot through which projects a bolt 28 from the frame work 25 for limiting the lateral movement of the bumper relative to the;

guide rail. This bolt is provided with 'a suit-- able nut and washer for holding the bumper into sliding engagement with the guide-rail frame. The spring 26 as shown presses againbt either end of the bumper 24 to force it toward the right, the extreme limit, its movement in this direction being limited by the bolt 28 coming into engagement with the bumper in the left hand end of the slot.

In the position shown in Fi 1, the elevator is going in the upward direction and the bumper wheel 17 is now in the maximum rocking position for the upward direction of the elevation The bumper wheel 17 is just beginning to ,ride off the cam surface of th e'buinper 24, and the spring 23 is in tension to bring the parts back to the normal or idle position as shown in Fig. 7. If the elevator were going in the opposite di recti'on the lever 16 would of course be actuatedv in the opposite direction and the retractile spring 23 would be bearing against the upper surface of the cut-out portion 22 in the bell crank lever 16, tending to bring the parts back to idle position as shown in Fig. 7. It should be noted that the spring 26 serves a double purpose: first, as means to maintain the bumper in its extreme right hand position to impart to the lever 16 its nosaess maximum movement regardless ofiany side play of the elevator, and secondly, as cushion means for the apparatus to prevent sudden jars and pounding due to high speed of the elevator and other causes when the bumper wheel 17 strikes the bumper The transverse slot in the bumper 2% is preferably slightly longer than the maximum side play of the elevator in order that there may be a margin of lateral play of the bumper in all lateral positions of the elevator with respect to the guide rail for thespring 9-6 to serve as acushioning ineans all times.

It will be noted by reference to Fig. 1 that a float 29 is provided with a stern protruding upwardly out of the oil tank to in clients the oil level, thisoil level being shown in dotted lines. This stern passes upwardly through a funnel-shaped member 30 which serves as a means for introducing lubricant into the tank 1. A cover 32 or any. suitable fornris also illustrated for excluoing dirt, etc, froni'the reservoir and collecting pan. Referring to Figs. 4- and. 5, a guard 31 for the oil disk is shown for guarding against the splashing of oil when the disk 10 is driven at a high speed and for directing the lubricant into the collecting pan 8. This guard 31 may be provided with ears (only one being illustrated} cut therefrom. and bent inwardly as shown to facilitate the collecting of oil from the disk peripheryand directing it down the incline of the thickened portion 33 of pan 8 into the pan. The guard 31 carries the wiper 35, the latter being secured thereto by means of a screw 37. It is tobe noted that the lever arm 16 in the normal or idle position shown in Fig. 7 is in avertical position; that the crank arm 19 may be provided with a plurality 0f pivot points (two being shown) to which the connecting link 18 may be connected to vary the throw of the gear segment relative to the throw of the bumper wheel 17; and furthermore the gear segment is symmetrically arranged with respect to the cranl: arm 19 and made. large enough to avoid runningoff the pinion in the maximum rocking movement for which the apparatus is designed. The foregoing is illustrative or" only one of the many -Eorms which my invention is capableof assuming and it is to be understood that all changes in form that come Within the spirit or my invention are in tended to be covered by the claims appended hereto. For instance, inasmuch as the number of lifting disks employed in any particular case depends upon the demands for lubricant it may be desirable to provide a plurality of disks, as is illustrated in Figs. 8 and 9 where threedi re shown mounted on a, common she," driven by means of a pinion 1E1" jv vith asegment 13, this segment b b mounted in turn on rock shaft it. Each disk supplies l lubricant to a collecting pan 8 and from thence to an individual conduit 9" leading downwardly to an int 'vidual receiving cup 6, each one of these cups leading to a distributor 3 as shown in dotted lines.
