- SPECIFICATION forming part of Letters Patent No. 288,978, dated November 27, 1883.

I Application filed August 31,1883 FNo model.\

To all whom, it may concern/.-

Be it known that 1, JOHN COX, of the city and county of Albany, in the State of New York, have invented certain new and useful Improvements in Apparatus fol-Drawing Liquids from Barrels, Gasks, &c., of which the fol.- lowing is a specification.

My invention relates to improvements in the construction ofsleeve-taps or pipes that are insertible in either the head or side of casks, barrels, and other vessels, and which are so arranged that compressed air may by them be conveyed into the cask or other vessel in such manner that the air, acting upon the surface of the liquid contained in the cask, will cause the liquid to pass up into and out of a dischargepipe which is contained in the sleeve-tap through which the compressed air is introduced into the cask.

The objects of my improvements are, first, to simplify the construction of the sleeve-tap and render it less liable to be injured during the operation of driving it into a cask; and, second, to provide proper facilities for the rapid removal and insert-ion of the dischargepipe out of and into the sleeve-tap. I attain these objects by means of the mechanismillustrated in the accompanying drawings, which form part of this specification, and inwhich- Figure 1 is a longitudinal section of my sleeve-tap and couplingdevice, the dischargepipe being shown in elevation; Fig. 2, a front elevation of the coupling device or clamp; Fig. 3, an inverted plan view, andFig. 4 a side elevation, of the same; and Fig. 5, a horizontal sectionof the sleeve-tap at the linew x on Fig. 1.

As represented in the drawings, the sleevetap A is made conical on its lower portion for the purpose of obtaining a close joint between it and the circumference of holes of various sizes that are formed in casks and other vessels for the insertion of devices for drawing th e con circumferential, as indicated by the complementary dotted line in said figure. The head a has in its upper end a chamber or recess for 5 containing an annular packing, B, of indiarubber or other elastic material, and the outer diameter of said packing should be made to fit snugly into the chamber for containing it, and its inner diameter should be sufficient to permit the discharge-pipeto slide through it without difiiculty. Below the head a the body of the sleeve-tap A has a side branch, (E, into which a nipple, G, is secured. Said nipple is formed so that an india-rubber or other flexible tube can he slipped thereon; and the inner end of said nipple is provided with an inlet valve, 0, which I preferably make of a single thickness of oiled silk that is drawn across the inner end of the hole through said nipple.

The discharge-pipe D is inserted longitudinally through the sleeve-tap A, and is fitted to slide easily through thebore of the head aand the annular packing B. Said discharge-pipe must be of sufficient length to reach closely to the bottom of the cask, andmay be extended outwardly to any requiredlength. The lower end of said pipe is closed over and provided with perforations that will permit liquids to flow into the bore of the pipe.

My coupling device is composed of the-following parts: A hub or nut, E, containing an internal screwthread, is connected by the side limbs, e, to a U-shaped flange, e, that is fitted to slide into the groove (1 of the sleevetap A. A hollow screw, F, is fitted to screw into the hub E, and is provided on its outer end with a head, f, or other means, by which a, rotatory motion can be imparted to said screw. A presser-foot, f, is loosely fitted to the lower end of the screw F, and is attached thereto in such manner that said screw can be rotated without imparting a like motion to the presser-foot. The screw F and its attached presser-foot are bored out, so that the discharge-pipe D can slide freely through them.

The sleeve-tap A, detached from the discharge-pipeD and the coupling device, is insorted into a suitable opening formed in the cask or other vessel from which the liquid is to be drawn, and is secured therein by striking said tap on its head a with sufficient force to make it hold by frictional contact. The coupling device is next attached to the sleevetap A by sliding the flange 0 into the groove a, and the discharge-pipe D is then; pushed down through the screw F, presser-foot f,

packing B, and head a until said pipe is inliquid, it will cause the latter to' pass out through the dischargepipe D. 'Thisappara tus can be readily removed from the cask by first slacking up the screw F, so as to permit the discharge-pipe D to be drawn out, and then detaching the coupling device, after which the sleeve-tap A can be easily displaced.

I do not broadly claim an apparatus com-- posed of a sleeve-tap provided With an elastic packing, a valved inlet air-opening, anda discharge-pipe, as I am aware that such a device is old in manifold forms; but

" What I claim as my invention is- The sleeve-tap A, provided witha head, at, whose boreis just large enough to permit the discharge-pipe D to slide therein, the said head being provided with an external groove, a, and a recess for containing the annular elastic packing B, as herein set forth, in combination with, the discharge-pipe D, contained in the sleeve-tap A, as herein described, and a coupling device composed of the nut E, having an open-sided flange, 6, formed to engage in the groove a, and ahollow screw, F, all constructed and arranged to operate as herein specified. 40
