July 23, 1935. s. T. WILLIAMS AIR OPERATED LIQUID TRANSFER SYSTEM Fil ed April 7, 1954 INVENTOR Pate'ntedduly 23, 1935 PATENT OFFICE Am ornnarsp LIQUID TRANSFER SYSTEM Selden '1. Williams, Bellerose, N. Y., assignor to A. Shrader's Son,

hi. Y., a corporation of New-York Incorporated, Brooklyn,

Application April 1, 1934, Serial No. 119,609

.6 01mm.- (01. 221 2a) The present invention relates to means and the method of transferring canned liquids-and more particularly to the transfer of lubricating oil from sealed cans to lubricant reservoirs or 5 other containers.

The practice of sealing lubricating oils for motor cars and other apparatus in sealed cans'so as to assure the purchaser getting what he asks for is rapidly, meeting with public favor. Toobtain in oil from such cans onee'nd thereof isll ually,

J I punctured or perforated, the oil drained therefrom and the can then discarded, the puncture made therein beingusually' of such character asto 'renderre-fllling of the can impracticable.

'5 An object of my present invention is to provide means for. facilitating --and expediting the discharge of oil and other liquids from hermetically sealed cans and simultaneously rendering the can non-refillable and non-reusable. A further object is to provide portable means for accomplishin: the transfer of a desired brand or? grade or ofl from asealed container. directly to a lubricant reservoir of an automobile or other device and thereby avoid multiple handling and insure v 25 against substitution pf the product desired.

- The foregoing and other objects ormy invention I accomplish by providing a portable carrier having a discharge passage leading therefrom, means for puncturing the can to permit the disto charge of its contents through said discharge passage and meansfor promoting said discharge} by fluid pressure'actin'g upon the can contents. The

- invention, which is herein disclosed in two preierred embodiments, will be. better understood 35- from the detaileddescriptionthereof which follows, when considered in conjunction with the accompanying drawing, wherein:

Plane 1 is a front elevation with parts broken away, showing one embodiment of my invention.

no, Fig.2- is a section taken substantially along the plane of the line 2-4 of Fig. 1, the can being Fig. 3 is a section taken substantially along the plane of the line 3-3 of Fig. 1.

as Fig. 4 is a section taken substantially along the plane of the line 4-4:: Fig. 5, showing another embodiment of my invention.

Fig. 5 is a section taken substantially along the plane of the lineS-S of Fig. 4. 1

Referring first to Figs. 1 to 3 of thedrawing, let A indicate a portable carrier of substantially rectangular form having a substantially circular basev 0 provided with a downwardly-extending central projection to and an upwardly-extending,

1 truncated, conical projection'la. adapted to function as a can-puncturing 'means', there being an axial opening 4a extending through said projections. The base on its upperface may be formed with radial ribs a upon which an endof a' can B may seat after being forced down over the projection 3a,.an d leading from the spaces between the ribs 5a are ducts 6a which connect with the axial passage 4a. If desired, the base a may be provided with an upwardly-extendingk'enclosing wall or skirt portion 1a.. The lower end of the opening to may be counter-bored and screwthreaded and may have connected thereinto a pipe of hose 2a, which, at its free end, may carry anozzle (not shown).

The top of the carrier is formed centrally thereof with an opening 8a through which is guided a threaded plunger C, which, at its lower end, carries a plunger head '0 having on its under face a central conical projection having a transverse opening therethrough which cornmunicates'with an axial: opening 40 extending through the plunger. {The under face of the plunger head- 0 surrounding the conical projection 2e may be provided with a disk of packing material for 'providing an air-tight seal with the top of the can B.

Screw-threadedly mounted upon the plunger Cabove the carrier'A is a hand wheel D having a hub formedwith a flange d which loosely seats in a recess provided by an overhanging flange 00 at the top of'the carrier whereby to provide a swivel mounting for the hand wheel D on the carrier. To prevent rotation of the plunger head 0 as it moves upwardly and downwardly due .to rotation of the hand wheel D, any suitable means such as a rib 9a extending into the opening 84 of the carrier for cooperation with a longitudinal groove in the plunger may be provided, as best shown in Fig. 3. 1

The upper end of the plunger C has connected thereto a coupling E carried by ailexible hose e leading from a source of compressed air or the like. For the sake of convenience, instead of this hose being directly connected to the source of fluid pressure supply, it is connected to a nipple. Illa on the carrier, and the carrier has a duct Ila extending therethrough, in which duct there is mounted a normally closed check valve lIa adapted to be opened by pressing inwardly upon a button Isa. The devicebeing a portable one, it is preferable that the valve operating button be conveniently accessible to the hand of shoperator which supports the device, and I have accordingly shown the carrier as provided. with an oflset. portion having an elongate opening Ila thereinto provide a gripping handle l5a, which is disposed directly below the valve operatingbutton "a soas to iacilitate'engagement thereof by the thumb of the operator.

In use, a can B from which the contents are to be discharged is held over theprojection 3a and the hand wheel D rotatedto move the plunger 0 downwardly so that the perforating'projection 2c thereon will penetrate .the top of the can, and

-.continued rotation of the wheel will force the can down over the perforating projection 3a to clamp the can between the plunger headand the carrier base a. As soon as the can bottom is puncturedvthe contents of the can will begin to flow through the openings to and 6a and may be checked by a suitable valve (not shown) placed in the discharge pipe 20., or said clamping action may be madeto take-place after the discharge nozzle is ingengagementin the lubricant reservoir to bercharged. After the can is properly clamped the valve [2a is opened by finger pressure upon the button 13a; whereupon air 'under pressure will be charged to the interior of the can through the hose e and ducts to and 3c. The air pressure will function to force the contents from the can and insure complete evacuation thereof; Afterith'e ca'n contents have been discharged, rotation of the hand wheel Din the oppositedirection will elevate the plunger head 0,-

.whereupon the punctured can can-be withdrawn from the'carr'ier and discarded. 1 1 1 In theembodiment of my invention shown in-.

. Figs. 4 and 5, the can, instead of being clamped between its ends, isadapted to be clamped around its sides and punctured atspaced points to render the can non-refillable or non-reusable. 'Acco'rding to this embodiment of my invention 1 provide an elongate'trough-like carrier 13" of arcuate cross-' section having end walls I. Substantially ce'n-'- tra lly of the carrier,- F on its convex side it is formed with a'depending lug or projection 2 having a duct 3 therethrough, in the .outer end .of which may be fitted a hose nipple or coupling -member 4) to which is connected at hose-'5 and to the other end, which extends into the concave, side'of the carrier, is fitted ahollow plug 6f-pro-. .vlded with a conical head I f having a transverse opening if .therethrough in communication with the ductif. The conical head 1; provides a spur for puncturing the side of a .can G when the latter is forced over said spur. To facilitate the clamping of a can in the. carrier, the latter .has

hand-grippingportion 9f, the said gripping portions' being provided with latching'*means.con-. sisting of a pivoted'link 3h carried by the portion in adapted to engage over the portion 9i and seat in a recess lof therein. Preferably the sum of the lengths of the arcuate components of the -carrier-F and the clamping arm H is less than the circumference of the can to be clamped therebetween so'as to permit the application or Y clamping pressure to saidcan.

Carried'by the clamping arm is a second can-puncturing means 4h of. similarconstruction 'to the can puncturing means If, the said memi I bet 4h; having a nipple portion extending through and beyond the outer face of the clamping arm H. Also carried by the clamping arm H and f 752 pivotally connected thereto at the point 5h is an arcuate member J disposed in substantially conf centric relation to said clamping arm and adapted for limited movement toward and away from said clamping member. Normally the member J is urged and held at its limit of movement away from the arm H through the medium -of a coil I spring 6h disposed around a pin in carried by the clamping arm and extending, through a slot 7 in the member J, the pin "1, having a head which limits the outward movement of'the member J Carried by the member J intermediate its ends and disposedfor cooperation with the outer end of the puncturing means "L is an air chuck K fof conventional construction having a. valve therein (not shown) which is normally held seated. by the air pressure supplied thereto through the hose k. The air chuck, "which is normally held out oferigagement'with the outer end offthe I puncturing means 4h,'is adapted to 'be brought into such engagement by downward pressure on the free end-01.2. the member J, whereupon-the K valve in said chuck will be unseated and an airtight seal will be made with the end of the puncturing means 411. to permit compressed air to flow,

therethrough. It willthus be seen thatin' order to discharge the contents from a can G it is first set in the trough-like carrier F, the clamping arm H is-moved to engage around the can, which act .functions to clamp the can to the carrier, and

substantially simultaneously puncture-the cans by both puncturing means If and in. To hold said can in clamped condition and relieve the operator from applyingmanual pressure thereto. continuously, the clip 3h maybe engaged'around -'35 the gripping" handleto seat in therecess. Inf therein. The member J is then pressed inwardly toward the carrier member to admit air under pressure to the interior of the-can above the surface of the liquid therein to promote the rapid and effective discharge of the liquid contents from clamping arm is unlatched and released, whereupon the punctured can may be withdrawn and discarded.

Fromthe foregoing detaileddescriptions it will eflicient portable means for transferring the liquid contents from a canto a receiving reservoirand for simultaneously rendering the can nonrefillable orreusable; It will also be appreciated .40 the can. -Whenthe canha's been emptied, the

45. be apparent that I have provided a noveland that while I have shown and described two em-' bodiments of my invention, I do not wislrto be limited to the details of construction disclosed since it will be apparent to those skilled in the art that such details ,ma'y be modified without departing from-the spirit of the invention.
