HNItBImfr W. LIVINGSTON, orHaMILroN, ONTARIO, CANADA.-

To all wliom It concern:

Beit known that `I-,'HRBERTKW.

INGs'roN, a' subject of "theyKing of Great Britain, residingat Hamilton, in the county of Wentworthjand Province of yOntario, Canada, haveinve'nted certain new and useful Improvements in Liquid-Dlspensmg De vices, of which the Afollowing is a specification.

My invention relates to improvements in4 liquid dispensing devices, and more partielllarly to devices for dispensing'heavy oilsi and filling motor vehicle gear cases and dif ferentials, and consists essentially of a -bulk container` provided With a vertically disposed cylinder which extends throughA and to Within a suitable distance above the bottom of the container and havin a plurality of annularly arranged ports ag oil and filling gear cases', differentials and the like, and automatically measuring the l oil While it is4 being pumped.

A further object is to provide such a de vire which will be adapted to expeditiouslypump the heavy oil which is generally utilized for the above specified purpose, lWithout it being necessary to exert the exhaustiveenergy requisite in the usfe of hand pumps of prior design. A still furtherobject is t0 provide a device ofthe class specified which Will be simple,

durable,'efiicient in operation and inexpensive to manufacture.

These together with other'objects .nay be attained by the construction, combination and arrangement of the parts as. will be hereinafter more fully-described, illustrated in the accompanying drawing, and pointed out in the claims hereunto appended. l

Reference bemg had to the drawing,

indicates the. bulk container which is supported. by "legs 2, and is provided with suitable handlesY Sfor lifting land carrying purposes.

A cylinder B extends vertically from a base 4 connected to the legs 2 by straps 5,

through a corresponding concentric opening in the floor 6 of the container, and to a substantial distance above sa1d floor. The said cylinder is open at the top, and is provided plurality ofv annularly larranged yes phragm 8, to lill With the liquid within the container, at the time the plunger C is at its liighest elevation in the cylinder. y

The plunger C is fitted with a plunger rod 9 extending through a guide eye 10 in a strapv 11, or other suitable device rigid with the container, and through an orifice in the I Upp. of the container, and pivoted to a lever which is connected by a double link 13 at its fulcrum end to the body portion of the container. The opposite end of the said Ilever is provided with a handle 14.

The container is filled through la suitable filling cap 15 in the top thereof.

The plunger C is fitted with a sealing washer 16 and provided with a valve for the purpose of admitting liquid into the cylinder during the up stroke and preventing formation of vacuum therein. This valve comprises a plate 17 rigid with a stem l18 sleeved in a lowerportion of the plunger, and provided at its upper end part with a disk 19 held in positionby a. pin 2O passed through said stem. A spiral expansion spring 21 is .inserted between the said vdisk and-said lower portion of the plunger. and tends to retain the valve in closed position.

Liquid is admitted to the cylinder through ducts 22 in tle upper portion ofV the plunger and ducts 23 in the lower up' stroke thereof, the ducts 23 being closed by the plate17 during the down stroke.

portion during the The space within the cylinder between the diaphragm S and the lower `level of the alined ports 7 which is also the floor line of the container, V1s adapted to contain a de! the down stroke of'theplunger bypressurev effected by the liquor under pressure of the liquid by suction. Thisvalve comprises ail plate 24 vertically slidable upon asteni 25 rigid with the diaphragm S. A spiral eX- -what I claim and desireto pansion spring 26 is inserted between the plate 2d and the base el, and tends to retain the plate 24 in contact with the diaphragm 8 and seal the passages 27 therein, during thea up stroke of the plunger.

The lower end of the cylinder communi`r Cates with a pipe QS which is provided with a hose 29 equipped with a suitable nozzle 3() to be inserted in the place vin which the liquid is to, be injected.

In case it bcdesired to measure oli' a quantity of liquid less than the measure contains,the connecting rod 9 is provided with a number of holes in which may be insert-ed a pinl adapted to Contact with the strap 11 and prevent the plunger from forcing the entire amount of liquid out ot the' measure portion of the cylinder. The position of said pin holes isl graduated to measure proportionate quantities of the liquid.

Having now fully described my invention,
