HENRY E. MARCHAND, OF ALLEGHENY, PENNSYLVANIA, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO WILLIAM J. BEGKFELD, OF SAME PLACE.

AUTOMATIC LIQUID-MEASURE.

SPECIFICATION forming part of Letters Patent No. 232,527, dated September 21, 1880.

Application filed June "23, 1880. (Model.)

To all whom it may concern Be it known that I, HENRY E. MARGHAND, a citizen of the United States, residing at Al legheny city, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Automatic Liquid- Measuring Apparatus, of which the following is a specification.

This invention has for its object to provide a liquid-measuring apparatus which, when set for operation from the outside, will receive from a connected source of supply and autol matically discharge a definite quantity of liquid, the inflowing liquid operating devices for sounding an alarm when a proper quantity has been received, and for registering the number of measurements.

It is especially dapted for use in measuring oils, molasses, and other liquids liable to soil the bands and clothing.

It consists, first, in the combination, with the receiving-casing of a liquid-measuring ap paratus, of an inlet-valve and an outlet-valve, a float arranged to operate said valves automatically through intermediate devices for closing said inlet-valve and opening said outlet-valve, and a device for opening said inletvalve from the outside of the casing at the commencement of said measurement, all con structed and arranged for the accomplishment of desired object, substantially as hereinafter described; second, in the combination, with the receiving-casing of a liquid-measuring apparatus, of an inlet-valve and outlet-valve, and a float arranged to operate said valves automatieally through intermediate devices for closing the former and opening the latter simultaneously, and subsequently closing the latter .when a definite predetermined quantity of liquid has been discharged from the casing; third, in the combination, with the casing, float, and automatically-operated measuringvalves, of a registering device arranged upon the outside of the casing and an operating lever or arm arranged inside the casing in the path of the float and istering device.

In the accompanying drawings, Figure 1 is a front view "of the apparatus with some of in dotted lines.

connected with said reg the interior parts indicated Fig. 2 is a vertical section 011 line a: a; of Fig. 1. Fig. 3 is a rear view of the apparatus with its back wall removed. Fig. 4 is a horizontal section on line 9 y of Figs. 1 and 3. Figs. 5, 6, and 7 are detail views.

The letter A designates the walls of the easing, transversely on the bottom of which is arranged a frame,B, for supporting the valves, valve and alarm operating devices.

0 designates an induction-nozzle passing through the bottom of the casing and base of the frame B, and having arranged within it a valve, 0, Fig.7, which is normally held against a seat, 0, by means of a spring, 0. I

From the valve 0 rises a stem, 0 passing upward through suitable guide passages formed in the crossbars b and I) of the frame 13, and at its upper end, which extends above the cross-bar l), the stem 0 has secured to it a horizontal arm, D, extend cross-bar toward the front of the casing, its front end being widened, and having a vertical opening, d, (see Figs. 5 and 6,) formed through it, to permit the passage of the stem 6 of a valve, E, which normally rests by grav- 7 5 ity upon a seat, 0, formed for it at the mouth of the discharge-spoutE, which passes through the bottom of the casing and the base of the frame B in the same manner as does the nozzle O.

The stem 6 is provided with a projecting head, 0 under which is arranged to take a latch, F, mounted on a pin, f, passing loosely through the arm D, and acted upon by a spring, f, to cause the latch to move under said head of the stem. Thislatch is provided with a tail, f extending rearward, for a purpose to be hereinafter explained. For detail view of latch, see Fig. 5.

A standard, G, projects upward from the 0 top cross-bar, b, ofthe frame B, and through an opening in the arm D, and from this standard Gr projects rearward a short stud, 9, under which is arranged to catch a shoulder, h, formed on a dog, H, pivoted in a slot formed 5 in the arm D, and havinga forwardly-extending head, h, which overbalances it to cause it to fall forward by gravity. (See Figs. 2 and 6.)

When the arm D is depressed, thus forcing roo ing above said 70 down the stem 0 and carrying valve 0 away from its seat, the dog H falls forward, and the shoulder h catches under the stud g, thus locking the valve open. When the parts are thus situated the latch F is caused, by the sprin g f to take under the head of stem 0, as shown in Figs. 5 and 6.

For depressing the arm D a bell-crank lever, I, is pivoted at its angle to a standard, I, mounted on the frame B, the short arm 2' of said lever extending forward over the arm D and provided with a toe, 2', while the long arm 2' curves upward and terminates in a head or hammer, i arranged to strike. a bell, 1 From the head or hammer i a loosely-connected rod, 70, leads through the front wall of the casing and terminates in a knob, 76. When the rod is drawn outward the bell-crank lever will obviously act upon the arm D to force it downward. From the top of the front portion of the frame B rises a standard, I, carrying at its top a horizontal sleeve, L. Into the rear portion of the sleeve L is fitted a cylindrical arm, N, held rigidly in position by a binding-screw, n, and extending rearwardly over the arm D to the middle of the latter. Upon the rear end of the arm N is fitted loosely a cap, N, in opposite portions of the wall of which are cut oblique slots 11, into which pins project from the arm N, the slots being in such position that when the cap is turned to the right, as viewed from the front, the studs, acting on the walls of the slots, force the cap rearward, when its head or closed end will strike the head of the dog H and force its shoulder h out of engagement with the stud g, when the arm D will be permitted to rise, throwing the bell-crank lever backward,so that the hammer on its long arm strikes the bell to announce the completion of a measurement.

From one side of the cap N projects a thimble,n ,into which is secured an arm,0, extending from a float, O, and from this thimble a cam, 42 projects downward. WVhen this float is caused to rise by the admission of a liquid into the casing, the cap N is turned on its arm, so as to beforced rearward, as before described, and when said float has reached a predetermined point, on being permitted to descend by the drawing off of the liquid, the cam n will strike the tailf of the latch F and cause said latch to become disei'igaged from the head of the stem 0, so that the valve E falls to its seat and closes the discharge-spout. Both the discharge and inlet valves will then be closed, and the knob must be pulled outward to place the parts in position to commence a11- other measurement.

A registering-dial, P, having a marginal series of numbers, is arranged upon the wall of the casin g, and from the center of this dial a screwnipple, 19, (see Fig. 2,) extends through the wall of the casing to receive a nut, P, between which and the dial the wall is firmly clamped, as shown in the sectional view, Fig. 2. Through the nipple p is passed a spindle, Q, carrying at its front end, in front of the dial, a pointer, Q. A pin, q, secures the spindle in the nipple. Upon the rear portion of this spindle is rigidly secured a ratchet-wheel, R, and loosely pivoted upon said spindle is a bifurcated arm, S, having its arms 8 s on opposite sides of the ratchet-wheel. Between these arms is pivoted, upon a pin, t, a pawl, T, the tongue of which rests upon the periphery of the ratchet-wheel at a point slightly above the pawl-pivot, in order to give the pawl a purchase upon the teeth of the said wheel.

Through the outer end of the lever S is arranged an adjusting-screw, U, the point of which stands in the path of the float O, sothat when said float rises it will strike the screw and raise the lever S, causing the pawl T to turn the ratchet-wheel and spindle Q, thus movingthe pointer in front of the dial to register the number of times the float rises, and consequently the number of measurements made.

The downward movement of the lever S is limited by a stop, 21, fixed to the wall of the casing, and ,by adjusting the screw U the throw given to the lever by the float may be so regu lated that the pointer will be moved the desired distance to properly count on the dial.

It will be understood that the movement of the float may be so arranged as to cause it to trip the valve-operating and alarm devices when the casing has received and-discharged any desired definite quantity ofliquid, which will form the unit of measurement of the apparatus.

The operation is as follows: The operator draws the rod 76 forward, and thereby causes the toe of the bellcrank lever to depress the horizontal arm D, which, in its downward movement, depresses the valve-stem and valve 0 0, thereby opening said valve and permitting the liquid to flow into the casing through the induction-pipe 0. Upon releasing the rod of the bell-crank lever the said valve 0 is held open against the upward pressure of the spring 0 by means of the dogH, which, during the descent of the horizontal arm D, swings forward so that its shoulder h will catch under the lug or arm 9 of the standard G. While the liquid is flowing into the casing the outlet-valve E is closed by gravity, and as the liquid rises in the casing the float is caused to rise.

During the depression of the horizontal arm, as just described, the latch F will be forced by spring-pressure between the said horizontal arm and the head 0 of the valve-stem e of the outlet-valve, as shown in Figs. 5 and 6. As the float rises the cap N will be turned on its arm, the walls of the oblique slots in the cap acting on the pins in said arm, so that the cap will be forced inward or toward the rear wall of the casing, and when the said float has reached a certain height in the casing the cap N will strike against the dog H, thus freeing the dog from engagement with the lug or arm IIO of the dog, which The s rin c u on such disen a einent J P 1 e has heretofore locked the valve 0 in an open position, immediately forces the said valve up against its seat, so as to cut off the inflow of the liquid, such action necessarily causing the valve-stem and the horizontal arm D to have a like upward movement. As the arm D risesit acts upon the toe of the bell-crank lever I, so as to cause said lever to strike the gong, and it also raises the valve-stem 6, so as to open the outlet-valve E. As the liquid now flows out through the discharge-spout the float descends, and when the said float has reached a predetermined oint the cam a of the thimble n connected to the slotted cap N,rwill strike the tail f of the latch F and cause said latch to become disengaged from the head of the stem of the outletvalve, thereby permitting said stem and valve to descendin order to close the dischargespout. Both the discharge and inlet valves will then be closed, and the knob must be pulled outward to place the parts in position to commence another measurement.

The number of measurements made are indicated by the pointer Q in front of the dial P, as hereinbefore described.

The apparatus herein described is intended as an improvement upon that which forms the subject of Letters Patent No. 221,333, granted to me November 4, 1879.
