SPECIFICATION forming part of Letters Patent No. 597,477, dated January 18, 1898.

- Application filed July 293 1897. Serial No. 646,357. (No model.)

To aZZ whom it may concern.-

Be it known that I, MILETUS J. INE, of the city of Viashington, in the District of G0 lumbia, have inventeda new and useful Measuring-Pump, of which the following is a speci fication.

The invention has relation to improvements in measuringpumps for drawing a determined quantity of a fluid from a reservoir or containing vessel and delivering it directly into the portable receptacle; and the objects are to simplify the construction and increase the efficiency of the mechanism and insure accuracy in movement.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, wherein- 'Figure l is a side elevation of the measuring-pump complete and vertical section of the pump cylinder and piston disposed in the fluid reservoir or tank. Fig. l is a detail of the delivering-nozzle, showing the valve secured therein. Fig. 2 is a plan view of the plate adapted to be secured to a floor above the tank and to which the pivot-ally-mounted stop is secured. Fig. 3 is a plan view of one of the cross arms or heads of the measuringframe and cross-section of the hollow pistonrod. Fig. 4 is a view in elevation of an auxiliary delivering tube or spout designed to be connected to the nozzle of the ump to fill deep or large cans.

This pump is particularly intended for use in measuring inflammable 11iidssuch as coal-oil, gasolene, and similar fluids-end is designed to be placed with the operating filling mechanism above a floorin one compartment, with the pump extending below the floor and into a tank secured and placed in a safe place.

Referring to the drawings, A designates a tank or reservoir of any suitable size and of a construction adapted to contain with safety an inflammable fluid. In this tank is secured a pump-cylinder 1 of any proper size and fastened in the bottom of the tank. This pumpcylinder is made of a capacity suited to pump and measure the largest quantity designed to be delivered at the nozzle of the pump at a single stroke. In the drawings I have shown the pump-cylinder as seated on a perforated stand or support 2, secured on the bottom of ends lodged on the flange of the stand and their upper ends bearing against the top or cover of the tank. A guide-frame for the piston-rod is provided, being composed of side rods 4 4, let through ears on the pump-cylinder, said rods being connected at their upper ends by a cross-piece 5, formed with a central hole through which the piston-rod slidingly operates and is guided.

In the bottom of the pump-cylinder is a suitable valve 6, opening upward in a wellknown manner. This part or portion of the pump above described I make no claim to, and it may be of other constructions suited to a measuring-pump having a reciprocating hollow piston-rod.

In the pump-cylinder is disposed the reciprocating hollow piston-rod 13, consisting of a metal tube of the desired bore to freely deliver the fluid through the nozzle. At the lower end of the piston is carried the pistonhead 7, fitted to the pump-cylinder and provided with a valve 8, opening upward, so that when the piston is moved upward the required distance to measure the required quantity of fluid and is then moved down to its limit of movement the quantity of fluid to be measured will be delivered through the nozzle into a can placed to receive it. The upper end portion of the piston-rod is curved over and directed straight downward, as at 9, and in the nozzle is placed a valve 10 to stop the drip, this valve being moved outward and away from the nozzle by the force of the dis charging fluid and returned to close the noz zle when the flow is completed or the pressure ceases by means of a retractile spring 11. On the nozzle end portion of the piston-rod is fixed a hook 12, on which is hung the bail of a light can while being filled, substantially as r causes the oontentstofroth andfoam rise outofthecan and. run down theoutcr surfacethereofonto thefloor, t-h us making a dangerous deposit, besides making'it neces 'sary to clean both the can and the door, To "allay this'produced :ebullition and prevent the overflow occasioned thereby limake'l the nozzle-piece let considerably longer: than usual, extendingwell downin-to the'can be ingfilled, so that thefluid will rise up and "around the lowergportion thereof and close the same and the can maybe filled to; come I pletion; withoutany appearanoeof the agitaused.

as the auxiliary nozzle piece is longenouglr to permit the reciprocationsofthe piston-rod. mThe upper portionof the tube is split, as

'- at 15 and is formed with a turn ord in flange I a, to take: over a head or ring on the 1102 I 'zler, WVhen large'vessel l st-measured into I and thedesired amount of fluid has beendis charged, the piston-rod may be lifted and the auxiliary tube or nozzle be detached therefrom and then withdrawn from the nozzle.

D designates a rectangular measuringframe secured to the piston-rod and so disposed thereon inrelation to the action of the piston that the limits of its adjusted and determined movements will cause the piston to discharge the requisite and desired quantity of fluid into the can or vessel at a single downstroke of the piston-rod. This measuring-frame D is of the following-described construction Referring to Fig. 1, l6 and 17 designate upper and lower cross pieces or heads, preferably consisting of duplicate alining bars (see Fig. 3) formed with oppositely-directed semicircular central recesses 18 18 totake in and hold the piston-rod and at the ends formed with recesses 19 19 to clamp and hold the respective ends of the measuring-bars. 20 and 20 designate the measuring-bars of the frame, having their upper and lower ends adjustablysecured in the cross-heads 16 and 17 by means of upper and lower nuts 21 21 threaded on the respective ends of the bars and disposed above and below the crossheads, substantially as shown in the drawings. The alining bars of these cross-heads are held together, clamped to the piston-rod by clamping bolts or screws 22 22 It will vb'ecreadi'lyperceivedthat these cross-bars 16 andllmay bemade;insingle'integral pieces formedwith apertures to takethepiston-rod and ,m'easuringbarsand secured to the pis ton rod by anysuitable fastenings. V r The 'measu'ringbars of the frame D are formed or provided withsuitable steps 23 23 7 designed to limit'rthelmovementof the p n mp and arranged therein or secured thereon at certain distances, determining: the-"required,

qu antities of liquid which are to be measured "bythe'moveinent of the piston, the distance be tween 'Jthe' stops or loops, and a stopping I i element-Tobe interposed int-heir path; The construction or formationof these stops in y theformofloopsinthemanner indicated in;

The stops or loops of the measuring-bars are disposed in alinement, with their inner ends adjacent to the piston-rod, substantially as shown in the drawings, and when the largest quantity is to be drawn they pass through the slots in the plate E, hereinafter described.

On the floor is secured a strong metal plate E, having a piston-rod aperture 24 therein through which the piston-rod works, and, from this aperture 2et, leads opposite the slots 25 25 through which the stops or loops may pass, or both of them, as when measuring a halfgallon. A

To stop the upward movement of the pump at the determined distances to measure a pint or quart, I pivotally secure on the plate E to move in the plane thereof a latch or stoppiece 26, formed with bent or curved arms 27 27 so formed and disposed that either may be moved ovelfthe slots in their path and stop the loops'in the measuring-bars from coming farther through the slots, and should it be desired to measure the full capacity of a stroke of the frame the stop-piece 26 is turned so that the ends of both arms thereof stand clear and away from the slots and thus permit both loops to move unimpeded therethrough. To hold the respective ends of the stop-piece 26 securely down over the slots, an overhanging flange 28 is formed on the plate IIC E around the pump-aperture, the overhanging part of the flange serving as keepers for the respective ends of the stop-piece when moved over the slots, as indicated in Fig. 2 of the drawings.

To adjust the frame to the measurements of the pint and quart, the upper cross-head of the frame is adjusted thereto by means of the adj usting-nuts on the upper ends of the measuring-bars, and the requisite adjustment for the half-gallon or greatest measurementis made by movement of the lower crosshead of the frame. After these adjustments have been made and ascertained the frame will need no further adjustment.

The operation and use of the pump are as follows: The pump having been set up substantially as illustrated and the measurement adjustments having been made as specified the vessel to be filled is hung on the hook on the nozzle. If a large vessel is to be filled, it is set on the floor, with the long nozzle-piece therein. The piston is then raised to the required and set distance and forced downward, when the determined and desired quantity of fluid will be discharged.

hat I claim is- 1. In a measuring-pump, the combination with a vertically-reciprocating piston-rod, of a measurin g-frame carried by the said pistonrod, composed of upper and lower cross-bars secured to the said piston-rod and measuring side bars, in the ends of the cross-bars, formed with loops disposed at determined distances in said bars, and means to limit the upward movement of the frame and piston-rod.

2. In a measuring-pump, the combination with a vertically-reciprocating piston-rod, of

a measuring-frame carried by the piston-rod, and composed of upper and lower cross-heads, secured to the piston-rod, and measuring side bars connecting the cross-bars and having stops therein disposed at determined distances, means to adjust the cross-heads on the side bars, and means to stop the upward movement of the frame and piston-rod.

3. In a measuring-pump the combination with a vertically-reciprocating piston-rod, of a measu ring-frame carried by the said pistonrod and composed of upper and lower crossbars secured to the piston-rod, and measuring side bars connecting the cross bars, and formed with integral loops disposed at determined distances; means to adjust the crossheads on the side bars, and means to stop the upward movement of the frame and pistonrod.

4:. In a measuring-pump, the combination with a vertically-reciprocating piston-rod, of a measuring-frame, carried by the piston-rod, having side bars formed with measuringstops, a suitably-supported plate formed with a piston-rod aperture and slots leading therefrom to'admit the passage of the measuringframe, and a pivotally-secured stop-piece formed with arms adapted to move over the said slots and stop the passage of the said frame.

5. In a measuring-pump, the combination with a vertically-reciprocating piston rod, of a measuring-frame secured to the piston-rod and having side bars formed with stop-loops, a suitably-mounted plate formed with a piston-rod aperture and slots for the piston-rod and frame-bars to pass through, and having a keeper-flange about the piston-aperture, and a pivotally-mounted stop-piece on the said plate formed with arms arranged to move across the said slots and under the said flanges.

In witness whereofI have hereto set my hand in the presence of two attesting witnesses.
