OIL-CAN.

Application filed April 3, 1906. Serial No. 309,588.

T 0 all whom it may concern:

Be it known that 1, HENDLEY W. HUB- BARD, a citizen of the United States, residing at Middletown, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Oil-Cans,

which improvements are fully set forth in the following specification.

This invention relates to improvements in devices of that class extensively availed of for injecting a charge of lubricant into a passage or openingdesigned to receive the same,

and more articularly to hand-operative de-' vices of t e class above mentioned, and whereby the injection of the lubricant is effected under pressure, such devices being commonly known as oil cans.

The object of this invention is to provide .juneture between its delivery-spout and the lubricant passage or opening into which said delivery-spout may be inserted, in practice; and which shall possess certain well-defined advantages over prior analogous devices.

The invention consists in the novel disposition and relative arrangement of the various elementary parts thereof; in certain combinations; and in certain details'of construction, allof which will be more specifically referred to hereinafter and set forth in the appended claims.

The invention is clearly illustrated in the accompanying drawings, wherein similar reference-numerals denote like'parts through out the respective views, and as to said drawings: Figure 1 is a side elevation of an oil can embodying my said improvements. Fig. 2 is a detail sectional view of a fragment of my improved oil can, the scale being enlarged, and there being shown in conjunction therewith a fragment of mechanism, as transmission mechanism, havin a lubricant passage or o ening, to better illustrate the practical app ication of the general construction.

In a general sense my improved oil can comprises a barrel, reservoir, or the like, for containing a lubricant, and a delivery-spout projecting therefrom, the latter having its free end enlarged laterally in all directions beyond the normal diameter of the contiguous portion of said spout.

Having reference to the accompanying Specification of Letters Patent.

Patented March 10,1908.

drawings, 2 denotes a barrel or reservoir for containing a lubricant, fitted at its respective ends with caps 3, 3, and provided with a delivery-spout 4 in direct communication therewith. I

5 is a piston-rod provided with a piston 5 at "its inner end, projecting through the cap 3 and provided at its out-er end with a hen-- dle 6, said piston being, accordingly, adapted to operate to and fro interiorly along the barrel 2, under proper manipulation. of the rod 5, as through the medium of the handle 6.

The parts thus far described arecommon and well kno n in the art to which my present invention appertains, and in practical operation, piston 5 is withdrawn, through proper manipulation of rod 5, from the devery end of barrel 2 to, say, its op osite end; barrel 2 is then charged with a ubricant, in any. convenient and well known manner, as by removing cap 3, or by suction during the operation of withdrawing the piston 5, as above stated, the free end of spout 4 being inserted in a body of lubricant; whereupon delivery of the lubricant thus contained in barrel 2, is efiected by manipulating rod 5, as under hand-pressure, so as to cause the piston 5 to move interiorly along barrel 2 in the direction of its' delivery end, as will be clearly understood.

In the practical operation of a construc tion such as thus'far described, the same having a delivery-spout whose free-,end portion is uniform, or approximately uniform, in diameter, lubrication of a wearing-surface by way of a lubricant'passage or opening 6,

(Fig. 2), cannot be effectively and satisfactorily accomplished, since such uniform spout seldom, if ever, snugly fits the lubricant passage or opening into which itis inserted, and hence there is ermitted a backflow of lubricant from sai passage or opening, under the pressure exerted on the lubricant contained in the barrel 2 and spout 4,

.which results in a material waste of the lubricant without the effective distribution adapted to exert a holding graspwvithin and at the entrance of 1111 oil-way. as 1'1. 'lhe sleeve 7 is formed as 11 distinct part, and adjusted to the spottt l l a telescopic movement. It is also, hy preference, 1111ifornily tapered front its greatest diameter towards the tip 111" spottt 4, and there pernianently held by any appropriate and ellknown means, annular nietallic stops 7 7, soldered or otherwise lirnily secured to spout 4, one closely at each end of the sleeve 7, being considered the most desiraltle. It ill he seen that a delivery-spout thus enlarged at its t'rceend may he urged snugly into a lubricant passage or opening 6, even if nonvarying in its diameter, and particularly so if the mouth of such passage be tlared, as clearly indicated in Fig. 2 of the (lravtings. Again, the tight juncture thus secured between the enlarged free-end of spout 4 and the lubricant passage into which it is inserted, by reason of the somewhat yielding character of the sleeve 7, not only 01:- viates all waste of the lubricant undergoing ejection from the barrel 2, hut by reason of the pressure brought to hear on the piston 1'), in the practical operation of the device, and which will he clearly apparent from the foregoing description of" same, a more etl'ective and satisfactory distribution of such luhricant over the \vearing-surface sought to he luhricated. is insured. llencc, it will he seen that my improved device is particularly \\ell adapted for the purposes for which it is designed, and further that the saute may he niodil'ied to 11 considerahlc extent. particularly as to the details of construction wherehy enlargement of the free-end ol spout 4 is attained, ithout materially departing front the spirit and principle of my invention.

Having thus descr1hed my lnvention, what I claim and desire to secure 11y Letters-Patent, is:

In an oil can. in cotnlxination, a barrel having a deliveryspont in direct communication thereuith, a piston operating in said harrel, a tapered, sonteuhat compressible sleeve telescopically adjusted to said spout at its free end, and adapted to exert 11 holding grasp ithin and at the entrance of an oil- \1 ay, and annular stops of rigid material adjusted along and fixed to said deliveryspout, one at each end of said sleeve, and hereby displacement of the latter in either direction along said delivery-spout, is prevented, suhstantially as herein specified.
