To all whom it may concern:

Be it known that I, SAMUEL TELFORD DUT- TON, a subject of the Queen of Great Britain and Ireland, residing at Marl Bank, in the city and county of Worcester, England, have invented certain new and useful Improvements in Measuring-Pumps, (for which I have obtained patents in England, No. 4,977, dated April 3, 1888; in Belgium, No. 85,073, dated February 19, 1889; in France, No. 196,176, dated February 19, 1889; in Germany, No. 3,730, dated February 18,1889; in India, No. 206, dated June 17, 1889; in New South Wales, No. 1,626, dated August 14, 1889; in Victoria, No. 7,012, dated August 20, 1889, and in (Janada, No. 31,040, dated April 4, 1889;) andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists of apparatus the parts of which are constructed and arranged and worked substantially in the manner hereinafter described to be used for rapidly and conveniently charging without waste the oil cisterns of lamps and for supplying a regulated quantity of oil to the said cisterns according to the time of year the lamps are in use or the length of time the lamps are intended to burn.

The said apparatus may also be used for charging and regulating the charge of liquid supplied to other cisterns and vessels to which it is applicable; such for example as oil cans and feeders.

I will describe my invention as applied to the charging of oil cisterns of lamps.

The apparatus constituting my invention consists essentially of a base plate carrying a pump barrel, valve chest, and valves, a hand lever for working the pump and appliances for regulating the stroke of the piston of the pump together with pendent suction and delivery pipes on the under side of the said base plate. The said apparatus is preferably mounted upon the tank or store vessel containing the oil or liquid combustible, the pendent suction pipe of the apparatus descending into the said vessel and taking a bearing in a socket on the top of the tank the said suction pipe being capable of pivoting in the said socket as a center when a partial rotation is required to be given to the apparatus. To

facilitate the motion of the apparatus the base plate carries rollers or feet which bear upon 1 the top of the tank.

In the valve chest are two clack valves, one at the top of the pendent suction pipe and the other between the pump barrel and the pendent delivery pipe. The clack or supply valve at the top of the suction pipe prevents the raised liquid returning to the tank and the intermediate clack valve insures the filling of the pump barrel from the tank on the lifting of the piston, the descent of the said piston closing the supply valve and opening the intermediate valve and causing the liquid to be forced from the pump barrel through the open intermediate valve to the delivery pipe which projects beyond the margin of the tank. The pendent delivery pipe is furnished with a valve which is raised and opened by the bottom or other convenient part of the cistern to be filled coming in contact with a soft button or projection at the bottom of the valve stem projecting beyond the bottom of the delivery pipe.

The hand lever by which the pump piston is worked is jointed to a vertical strut or arm on the base plate or pump barrel. The end of the hand lever projects beyond the joint on which it turns and to the said projecting end a coiled spring is attached. By means of this coiled spring the hand lever is lifted and the piston raised in its barrel thereby causing the said barrel to be refilled with the oil ready on the descent of the said piston to be forced into the delivery pipe. By means of an adj ustable stop arrangement the quantity of oil delivered at each stroke of the piston may be regulated. The stop mechanism may consist of a vertical arm on the pump barrel pro- Vided with a series of holes into one of which a stop pin may be inserted and locked in its adjustable position. The hand lever in its as- 5 or partly surrounding the supply tank may be used. On this bench or table the cisterns to be filled are placed and as they are within 1 easy reach of the hand of the attendant they may be rapidly charged and replaced on the bench, the operation during the charging operation being turned on its pivot from time time so as to bring the delivery pipe within 7 easy range of the cisterns on the bench or table."

charged without waste than by the method burn and hence considerable economy will be effected.

Fig. 6 represents in plan a modified delivery spout. Fig. 7 represents in section drawn to a large scale the delivery valve and pendent spout represented in Fig. 1 the said Fig. 7 exhibiting the said delivery valve pressed up and opened by the pressure of the lamp cistern and in the position to deliver oil into the said cistern. Fig. 8 represents a portion of the apparatus showing the application to the top of a circular tank upon which the apparatus may rotate. Fig. 9 represents in section, Fig. 10 in end elevation, and Fig. 11 in plan the apparatus arranged to be fixed on a bench or table the cask containing the liquid to be delivered being stationed beneath the said bench or table. Fig. i

Fig. 13 represents in longitudinal section and Fig. 14 in plan the apparatus fixed to a store tank or other vessel from which quantities of liquid are to be supplied.

The same letters of reference indicate the same parts in the several figures of the drawings.

I will first describe the arrangement of the In Fig. 2 the bot- Fig. 4. represents in elevaapparatus represented in Figs. 1, 2, 3 and 7. A is the cask, tank or vessel containing the oil (or other liquid) to be supplied to the oil cisterns of the lamps, and a is the suction pipe of the apparatus screwed or otherwise fixed below the suction valve b; b is the intermediate valve and b is the delivery valve, the said valves 1), b being situated in the valve chest d and the delivery valve 12 being situated at the top of the pendent delivery spout c the stem of the said delivery valve passing down the said spout. The bottom of the stem of the delivery valve 1) has fixed to it a soft button or projection 6 The man- By the use of the said apparatus and ap-; pliances, lamp cisterns and other vessels can not only be more expeditiously and accurately v ner in which the delivery valve 19 is lifted and opened by the pressure of the bottom of the oil cistern 1) upon it is seen in Fig. 7, where it will also be seen that the pendent delivery spout c is connected with the valve passage in the valve chest cl at c, the top 0 of the spout c forming a seat for the said delivery valve b Z is a guard forprotecting the pendent spout and delivery valve from I will now proceed to describe with referl piston e ispreferably furnished with leather washers on either side for causing it to accurately fit the pump barrel. The suction valve 1) at the top of the suction pipe at prevents theraised liquid returning to the tank and the intermediate valve b insures the filling of the pump barrel from the tank on the lifting of the piston e, the descent of the said piston 6 closing the supply or suction valve 5 and opening the intermediate valve 1) and causing the liquid to be forced from the pump barrel d through the open valve 19' to the delivery spout 0; his a coiled spring connected to the projecting end of the hand lever 9. By means of the said spring h the hand lever g when loosened, or the pressure on it relaxed, is lifted and the piston eraised in the pump barrel d thereby causing the said barrel to be refilled with oil ready on the descent of the said piston to be forced into the delivery spout c. The hand lever 9 works between the forked stop guide 2' (see Figs. 1 and 13). In the guide i holes 2" are made, into any pair of which the stop pin i may be placed. The pin 2' acts as a stop for the hand lever g for the purpose of regulating the quantity of liquid to be delivered at each stroke of the piston.

In Figs. 4, 9 and 10 other arrangements of adjusting stops for regulating the upward motion of the hand lever g are shown. In the arrangement Fig. 4: the edge of the forked bracket 1' is furnished with teeth with which the sliding adjusting stop '6 can be engaged and clamped at any desired height. In the arrangement Figs. 9 and 10 the adjustable stop for the hand lever g is marked 2' and is clamped at any desired position on the bracket i. In each of the arrangements the guide may be marked or graduated for indicating the quantity of liquid delivered according to the travel of the piston and the stop arrangements may also be used for regulating the downward motion of the hand lever. n is a tray for catching any drippings and returning the liquid so caught to the cask A. The said tray carries the filling apparatus and is furnished with a bush or hollow pivot 91 which is capable of turning in a hole in the cask A for the purpose of turning the delivery spout 0 into the required position during the filling of the oil cisterns. Instead of raising the piston in its barrel by means of a spring at the extended end of the hand lever g, the said piston may be raised by a spring under it as shown in Figs. 4:, 9 and 13 where the said spring is marked 4". The pendent spout and delivery valve may be constructed in the manner represented in Figs. 9, 12 and 13 for filling oil cisterns having long necks. In these modifications the delivery spout is made of the fixed outer part c and the inner sliding part or spout proper c the latter part carrying at its top the valve 17 The part c is tubular and constitutes the stem of the valve. Holes at j, j are made at the top and bottom of the combined spout and valve stem 0 to allow when the valve is raised from its seat of the entry of liquid into it from the valve passage d and the escape of the liquid from the bottom of the spout into the lamp cistern. On the bottom of the sliding delivery spout c is a soft button b for the oil cistern to press against for raising the valve from its seat. To prevent leakage between the two parts 0, c of the delivery spout, a hexagonal collar 7: provided with a leather washer or packing Z is screwed to the bottom of the fixed part c of the delivery spout. The delivery valve may be held in its open position by the arrangement represented in Fig. 13. In this arrangement the part c of the delivery spout is capable of sliding and is furnished with a hook m and the valve case with a second book m with which the hook 1% may be engaged and disengaged at pleasure by raising and lowering the said part c.

The parts of the modifications Figs. 4c, 5, 8, 9, 10, 11, 13 and 14 which I have not described are marked with the same letters of reference as corresponding parts of the arrangement Figs. 1, 2 and 3 and their action is the same.

Having fully described myinvention, what I claim, and desire to secure by Letters Patout, is-

1. In a charging apparatus, the combination with a hand pump provided with suction and delivery valves,and a suction pipe adapted to be inserted within the storage reservoir, of a spring for forcing the pump piston to its raised position thereby charging the pump barrel with liquid, an adjustable stop limiting the upward movement of the piston, and a delivery pipe provided with a tappet valve normally preventing the discharge of liquid from the said pump barrel, and provided with a central stem adapted to be pressed upward when the said delivery pipe is inserted in the reservoir to be charged, substantially as and for the purpose set forth.-

2. In a charging apparatus, the combination, with a hand-pu mp provided with suction and delivery valves, of a spring for forcing the pump piston to its raised position thereby charging the pump barrel with liquid, the base plate for supporting the pump and provided with a tray for catching the drip, asuction pipe passing through the said base plate and pivoting the said pump upon it, and a delivery pipe provided with a tappet valve normally preventing the discharge of liquid from the pump until swiveled around clear of the said tray and inserted within the service reservoir, substantially as set forth.

3. In a charging apparatus, the combination, with a single-acting hand pump provided with suction and delivery valves, of a spring for automatically working the pump in one direction, an adjustable stop for limiting the stroke of the pump so that it may discharge a prearranged quantity of liquid at each outstroke, a hollow base plate or tray for catching the drip provided with a nozzle for returning said drip to the service reservoir, a suction pipe pivoted in the base plate and passing centrallythrough said nozzle,whereby the pump may be swiveled around upon the said base plate, and a depending delivery pipe provided with a separate discharge valve adapted to be opened automatically when the said delivery pipe is inserted within the reservoir to be charged, substantially as and for the purpose set forth.
