The objects of this improvement are aszfol- First. To so onstrueta springbottom oiler that no soldered joint is required to connect 's uch spring-bottom with the sides of the res- `ervoir, thus rendering it less liable to become wvleaky by theiaction ofthe bottom, or by being placed in a hot position than spring-bottom.

oilers of 4theordinary construction.- This is Eaccomplished by'forming the spring-bottom and the sides of the' reservoir of one-piece, and

vjoining the sameto-'a rigid cover, the joint being. in an elevated position,4 where it cannotV be melted when the oiler. is placed upon a hot,

This annular space corresponds in depth to the movement to be given to the inner spring-bottom, and when the thumb is pressed on the external head, `Gr,the springsaid head rests'upon the flange of the 'rigid of the elasticity of the yielding or spring bot tom, and beyond which it cannot be forced.

rior or lower part thereof must approximate in form to a seiniisphcrc in orderfto form' a Amongfhc self-balancing oilels heretofore made one kind has the-entire external surface rigid oriuflcxiblc,'such i'igidity or inilexibility constituting its principal defect- .since the oil cannot be-c'xpelled by pressure against the side or bottom, butvcan only drop or flow out when it is inverted and shaken. Another kind has a se1ni-spherical bottom without seam or opening, and a ilexif ble' top, by compressing which theoil is ex'` polled. IThe position and operationof this flexible top-are its principal defects, it being extremely liable to become damaged :by 'bruisf ing and puncturing,.and is easily and quickly overstrainedinthe act of compressing itl to.

expel the oil. In order, therefore, to construct an improved self-balancedoiler in whichthe'se .defects shall be obviated, some part or portion must be made yielding or elastic, and yet such. elasticity must not be' in the top. Consequently, I inake the top of the oiler rigid, and since its lower part must be rounded or be made to approximate tothe forrnof a semisphere in order to become self-balancing, and

since, when metals are 'spunor stampedjinto that shape they become stiff Aand unyieldin'g,l

lit follows that the .desired elasticity 'cannot be obtained except by pe'rforating or forming an opening-in it andinserting anvauxiliary yield-` ing bottom in such aposition that it can be reached and compressed and operated' through the said opening. 'Such .auxiliary yielding part should be placed directly above .or over the perforation, .or in proximityto it, softhat 1t can be easily operated with the thumb and yet not interfere'with the automatic 'or' sel'ff rightingmovement of theoile'r. Suchauxili; ary yielding bottom may be secured in any suitable way, and in order to avoid a soldei-ed jointwithin the oiler nearits' lowel` part, v. where .it would be more or less' inaccessible,

and which might becomeleaky, -if theoiler is set on astoveodr other hot surface, it is advantageous to carry upthe edges'or sides of the yielding part high enough-to be'safe from injury from such acause. In tliisexarnple of my inyention lv have continued the sides of theyielding partnp to thefull-'height of the body of the oiler, thereby avoidinga soldered joint at or near the lower part of the oiler, and' pref.v

venting liability vto leakagetherefronr. The advantages of this arrangement andconstruction arethat the oilenwill not leak, nor is it liable to become leaky by use,'its-external surf face being rigid except at the point where the thumb-is placed.. It presents neither flexible nor yielding top or bottom to become injured from liability tobe puncturedfor bruised; it willalways standin averticalvpo'sition, or, if upset, will right itself and return to such position; its'yiclding bottom cannot. be injured or strained by compression; 'consequently it will always retain its spring, and is always in condition to eject the oil; it is vcrydurablo,

bruising or battering by'dropping or' rough usage not affecting its operation.

The letter- A designates the tube or nozzle 'of the oiler; B `its cover or top'. 'Thclat-ter isrigid in this example, and is connected to thetube or noz- `zie by a screw-joint. The parts AB C a're` seen 'together in Iig. 2, which represents an oiler complete vand ready for use without the lprotection of the shell D, which in thisexample forms its outer rigid and rollipg sur face.. `Vihen the bottom K is made to spring upward, oil will be forced. out through the end of nozzle A. The rigid exterior surface, l),

The internal head, H, of-.the button GHvisplaced within the rigid exterior, D,I so as to rest -on and be sustained by the ilange t', its center part, which is perforated, projecting down past the flange and fitting loosely within it. The thickness of the head `H is such that i't'will be about equal to the distan-ce between the flange i and the lowest part of the yielding bottom K when the said yielding bottom is placed .withili the rigid exterior D. -The external head, G, has a pin, O, projecting centrally from its upper surface, and which is pushed up through the head- H and riveted. The diameter of the head Gis greater than that part of thehead H which proj ects through the perforation, and itsedge consequently extends beyond in aline parallel with and below the flange fi, the length I of the centerpart' or body of .the head H Where it projects through .the perforation ,determin ingthe distance between the head Gand the- Vunder side'of theflang'e. It is not intended that the head Gshall touchthe supporting ness or-le'ngthof said head being such that.` when -it -isriveted tothe .head H it will not reach such'supporting-surface..`1 The -letterUdesignates the space left be `tween the ilan'ge and the upper face of the head G'when theoilen is-in a stateof rest; fand, since thehead Gcannot passthe ,flange that when thebutton', composed'cf the heads G Hxis pushed-.upward by the person using the oilerfit can only'm'ove' through thespaceor 'distance.U, and therefore the yielding surface cannotbe sprung o r moved upward a greater distance.

In carrying out that partof myv invention which consists in extending the flange oredge of the elastic bottom upward, and so forming both the sides andelastic bottom of one piece of metal, I had to secure a. considerable degree of hardness in one part and considerable softness in another part-that is tosay, the part forming the bottom is required to elastic, iu order t0 spring, while thepart in- "is made to approX1mat-e in form to a Sinni-,

surface on wll'ich the oiler stands, the thickwhenthe headis pushed upyrard, it .follows be hard and. Y

tended for the sides requires, on the contrary, to be soft to allow it to be spun. As the same sheet of metal doesnot possess these two opposite qualities, and a long series of experiments by the-methods ordinarily used in stamping, spinning, and partial annealing failed to produce the required shape from sheet brass possessing the requisitehardness for the springbottom, I invented the following process: Sheets of soft brass are first eut up into blanks of theA proper diameter. These blanks are then 'secured or 'clamped to the flat'fae'e of a chuck-placed on the mandrel of a lathe capable of revolving atahighveloeity. The clamp which confines theV blank to the face of the ehuck is in the form of an annular ring, the inner diameter eveeeding somewhat the diameter of the oiler-bottom. A compressing spin ning-tool is then pressed against the outer face of the revolving blank at its center, and is moved outward under a slightly-decreasing pressure until the tool comes in. contact with the inner circumference of the elampingring, when its motion isarrested. This operation has the effect of compressing and hardening the eentral portion of the blank to a diameter corresponding to that of the spring-bottom required. It also stretches the metal somewhat,

and the blank, when taken off, appears in seesoft soli.

*1 It is then placedin the die of a drop-press, and the bottom part, K, Fig. l, is'stampedA to the required shape. In this formit is clamped against the end of a revolving chuck, and the soft sides spun up to the required height. The edgeof the metal,

whether spun up or not, is united to the rigid vshell by any suitable means.4 i
