LUBRICATOR.

Drignal Ne.^`l,186,643, da

lubricators are frequently located, by necessity,- at places Where d n't and grease ac-' 4cilmulate on. thennfso thattheir" operation is frequently very dlstasteful as Well as dit- Vticult'and thereA is a tendency onf` the part of the operatorto neglect them/'This is especially true in motor cars and other pou'er driven vehicles. '1

lt is the object of my present invention to make the operating 'of a hibricator easier and less distasteful. to avoid any exposed grease. which invites dirt to aecumulate. and to make the handlingl of thwpply of-lulni cant easy and not unpleasant.

In accomplishin;r this object I put up the lubricant in collapsible tubesi preferably' nozzles; and connecting v these collapsible tubes to the apertures of the lubricator cups `by'such nozzles. rlhen by 'compressing the tube the lubricant maybe fed to the surface' to be lubricatethas required. This compression may beobtained in any desired manner, but most conveniently by a. suitableI key. Vhen the tubefis emptied a full tube may be easily substituted for it.

The accompanyingdrawings illustrate my invent-ion.

Figure 1 is .a sectional. View of one form of the lubricator with a collapsible tube ot lubricant associated ivithit; i

i a collapsible Fig. 2 's 'a View"showingi tube oliiluln'icant` with an yextended nozzle; and i lligsji and 4 are sectional and plan views respectively of a grease cup with Wl1ich`the dericesliown in Fig. 2' may be removably associated. f

ln the arrangement shown in Fig. l. there is a grease cup if), whichl is shown as hav im;y anexternally screw-threaded projection il by which it may be associated with the device to be lubricateth there being a duct 12 which extends through such projection ll to conduct the lubricant to the vsurfaces ted January 4, 1917 Serial No. 834,583, filed reissue led April 27, 1922. Serial No. 557027..

'openingh not in use itsl outletl may be suital April 2'?` 1914. `Application for to be lubricated. collapsible tube l13 forthe lubricant is removabli7 associated in any desired grease-tight manner with the ,grease f cup 10. so .that when compressed it will discharge 'lubricant into and through lthe aperture 12 to the surfaces to be lubricated.- This tube forms a lubricant container which hermetically sealed sare at the discharge opening.v In the arrangement showlnthe collapsible tube 13 is provided with a noz zle 14 which fits into an opening 15 at the inletend ofthe duct l2; the nozzle 14: andc 15 conveniently being screw-4 threaded to provide a conven attachment. Y If desired. a 'washer 16 may be l'ilaced between the' collapsible tube and the ient means of 2 rrease cup to seal'the joint-more efectivetv, l

`in is forced through the duct 12to'the'sur-v f faces to be lubricated. 4A convenient Way of compressingr the tube is by a key '17;'-f

ulrich fits "over the permanently closed 'end o'l' the tube in a welll-'known manner and when turned tlattens the tube and. iv'inds it up on itself. thereby forcing out 'the con-` tents ofthe tube.h l i' lhe grreaseicup may have associated there- "with a removable cap -19 for inclosing the" collapsible tube, this cap beingA f:`istened to,r

b v having a spring' fit over al flange lllot th'ejA `"reasc cup. lt' desired, the'cap v15% 'maybe' longitudinally slotted to receive the key 17. the slots serving as guides for the key. 'ith 48,5- the grease cup in any suitable manner, as v,

this.arrangement no lulu'icant can escapeff' from the tube to exposed parts. so that coinparativc cleanlinessy is maintained, andthe operation 'of the lubricator is renderedfless distasteful. When a tube is emptied, the cap 18 may be removed. the empty:tube'detached, and a fulltube attached in its place, and the cap 118 replaced. ln case lubricant of different cmrsislen `ies is used. as inhot and cold'- weather` thev tubes may be changedtritliont waste and/with ease as desired. vPractically' all contact with dirt and z i'rease is avoided both. in connection with the grease cup and' in dealing, with the. tubes.

ily covered,` as by an internally screw-threaded cap 20 fitting the nozzlelk In the arrangement just described th collapsible tube is ordinarily left in place until empty unless it is desired to remove it W'hen a tube is' i sooner as for changing the tubes. 'here it is not' desirable to lave the collapsible tube in place the arrangementv shownin Figs. 2, 3, and 4 may be used.. Here insteadA of the slotted cap 18 of F ig. 1, a fiat cap 25 is .provided for the grease cuplf), for closing the latter, and the collapsible tube ,13 is put in place only when the ca) Q5 is moved y,to exposethe inlet end of tl'ie aperture of the grease cup, and is removed when the desired amount .of lubricant has been forced, as bv the keyl-. vto the surface to be'lubricated.

If desired. a nozzle extension 26 may be provided for the collapsible tube, such nozzle extension conveniently having one end in the forni of a socket 27 adapted to receive the discharge end of the tube and the other end adapted to be associated with the inlet e-nd of the aperture through the grease cup 'and also to receive the cap 20. The nozzle exvtension may be'otl any suitable shape, and either stiff or flexible This nozzle extension greatly facilitates the reaching of the more inaccessible grease cups.

Itis not necessary that the part vvhicliI l have called 'the grease cup be nonfintegral with the associated pait of the mach-ine hav- 'ing the surface .to be lubricatedA` for by the terni grease cupi I mean merely a device having a. duct for leading yto a-surface to be lubricated. l
