SPECIFICATION formingpart of Letters Patent No. 665,390, dated January 1, 1901.

Application filed August 5, 1897. serial No. 647,218. (No model.)

To all whom it may concern:

Be it known that I, JOHN WILSON BROWN, Jr., a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvementsin Registering-Pum ps, of which the following is a specification.

The main object of my invention is to construct a measuri ng-pu mp that will accurately measure the liquid pumped and which need not be primed.

A further object of the invention is to provide a pump that can be accurately and cheaply manufactured and which can be readily taken apart for cleansing or for repairs; and a still further object of'the invention is to so construct the pump that it can be inserted into a comparatively small opening in the barrel.

My invention is especially adapted for us in pumping molasses and syrups and like liquids from barrels, and it is a substitute for the measuring-faucet commonly used for this purpose.

In the accompanying drawings, Figure l is a view of my improved molasses-pu mp. Fig. 2 is an enlarged sectional view of the upper end of the pump. Fig. 3 is a sectional plan view on the line 3 3, Fig. 2. Fig. 4 is a vertical sectional view of the lower portion of the pump on the line 4 4, Fig. 6. Fig. 5 is a vertical sectional view on the line 5 5, Fig. 6. Fig. 6 is a sectional view on the line 6 6, Fig. 4; and Fig. 7 is a sectional view on the line 7 7, Fig. 4:-

The pump is made in three sections namely, a stem A, a head A, and a pumpcasing B. The head A is secured to the upper end of the stem A and has a tubular extension A forming the outlet-nozzle of the pump. Theheadalsocarriesthedrivingmechanism, as well as the registering mechanism, of the pump. The pump-casing B is attached to the lower end of the tube A and contains the pn mping mechanism proper, which is connected to the driving mechanism through a rod extending through the tube A. I make the outside of the pump-casing B concentric with the tubular stem A, so that I am enabled to reduce the amount of work necessary in manufacturing the pump and Y make it neat in appearance. Also by having the parts concentric the diameter of the hole through which the pump must pass into the barrel can be just the size of the casing, and the pump can be readily inserted into or removed from the barrel.

On the stem A of the pump is clamped a sleeve C, having flanges c, which are preferably secured to the upper head of the barrel, so as to prevent the pump moving when once placed in position. On the lower portion of the pump-casing B are spurs c, which rest on the interior surface of the bottom edge of the barrel, so that when the sleeve C and the spurs are fixed the pump is perfectly rigid.

The upper end of the stem A is screwthreaded in the presentinstance, and the head A is screwed upon this end of the stem, and there is a passage in the head communicating with the passage in the outlet extension A At the end of this extension is a valvechamber at, having a valve-seat at the nozzle, and in the chamber is a valve E for cutting off the flow of molasses from the pump in order to prevent dripping after the receptacle is filled with the required amount of molasses. This valve is flush with the mouth of the nozzle when it is closed, so that there are no exposed cavities at the outlet of the pump for the accumulation of the molasses, which would attract flies and other insects. By making the valve flush, as shown in Fig. 2, both the bottom of the valve and the nozzle can be wiped clean. The valve in the present instance has an inclined slot 6, in which rests a pin 6', projecting from the casing. The valve is provided with a suitable handle e so that on turning the handle the valve can be raised or lowered.

Projecting from the head A is a stud a, and on this stud is a bevel gear-wheel D, having a handle d, by which it is turned. This bevel gear-wheel meshes with the bevel-pinion D, having its lower bearing in the head A and its upper bearing in the present instance in a plate F, mounted in a case A which in this instance contains the registering mechanismf The axis of this pinion D is coincident with that of the tube A, and the lower bearing is provided with a suitable 10c packing or stuffing box d. This stuffing-box upper end of the hub is a socket h, and in the pass each other and to slide.

lower end of the bevel-pinion D is a socket.

Extending from the pinion to the hub is a shaft G. This shaft in the present instance is square, and the sockets in the hub and in the pinion are shaped to conform to the shaft, and as the axis of the pinion is coincident with the axis of the tube A and the hub is cocentric thereto the shaft G will be inclined or diagonal with respect to the axis of the tube. The connections are comparatively loose, so that the eccentrically-sitnated hub can be readily driven from the concentric bevel-pinion. Furthermore, the shaft is not attached to either the bevel-pinion or the hub, so that when it is desired to remove the pinion or the hub either one can be removed by simply withdrawing it from the shaft.

Sliding in the hub H are two blades h 7L2, fitting the cam -shaped chamber 13 of the pump-chamber, governing the sliding movement of the blades in the hub. The blades are cut away at the center to allow them to Other common forms of blades may be used without departing from my invention. The hub in the present instance rests upon a plate B and has its lower bearing in said plate, the upper bearing of the hub being in the casing.

B is the cap-section, which is screwed into the end of the casing B and holds the plate B in position against the casing. The inletport b is formed in the plate B and also in the cap-section B as indicated in Fig. 5. The inlet-port communicates with the chamber B at one side, while the outlet-port 19 formed in the casing, communicates with the upper portion of the chamber at the opposite side. The cap-section B in the present instance has feet provided with spurs, which are forced into the bottom of the barrel, so as to rigidly hold the lower portion of the pump, raising the cap sufficiently off the bottom to allow the molasses to enter the inletopening. I prefer to screen the inlet-opening, so as to strain the molasses as it enters the pump, preventing sticks and other foreign matter entering the chamber and clogging the pump and barrel. J is a screen within the cap section B for this purpose.

Above the pumping-chamber B in the present instance is the valve-chamber, in which is a valve-plate I. In this valve-plate are one or more seats itwo in the present instance for the valves I I. The seats are tapered, and

the valves are tapered to correspond to the seats and have stems which are guided by spiders carried by the plate, so that as the hub is turned the molasses will be forced up through the outlet-passage b into the valvechamber and will pass the valves and enter the tube A.

The valve-plate I is supported by the casing B and is held in place by a reducing-sleeve B which is threaded and is screwed into the casing B, and the lower portion of the stem A is also threaded and screwed into the threaded portion of the reducing-sleeve. It will be understood, however, that in some instances this reducing-sleeve may be dispensed with and the stem A screwed directly into the casing.

I will now describe the mechanism for registering the amount of molasses passing through the pump.

The bevel-pinion D, which is mounted in the head of the pump, has an eccentric-pin (1 on which is mounted a planet gear-wheel F. This wheel has two sets of gear-teeth ff, and the two portions of the wheel are of different diameters. The teeth f mesh with teeth f on the fixed plate F, and the teeth f mesh with the internal teeth f 011 the wheel F connected with the dial-hand F", so that the dial-hand will only move a Very short distance for each revolution of the bevel-wheel D. In the present instance the dial-hand moves one sixty-fourth of a turn to one turn of the pump. The arrangement of the teeth and the relative diameters of the wheels will depend upon the quantities indicated upon the dial and the capacity of the pump to lift a certain amount of molasses at each revolution.

It will be seen that the pump is so constructed that when it is wished to remove the pumping-hub from the casing the cap and plate at the lower end of the pump can be detached and the hub withdrawn, as it is not secured to the shaft, but simply loosely coupled to it. The same is the case with the driving-pinion D, mounted in the head of the pump, and this can be readily removed by detaching the plate F. Moreover, the shaft being detachably connected to the hub and removable through the bottom of the tube said shaft can be readily removed without disturbing or necessitating the removal of the driving pinion or wheel D or the packing.

The operation of the pump is as follows: On turning the handled bevel gear-wheel D the hub H and its blades are turned within the chamber B, and a given quantity of molasses will be forced up into the passage a in the stem and in to the extension A The valve E being lifted, an amount of molasses will be forced out of the nozzle equivalent to the amount pumped,and simultaneously with this action of the pump the registering mechanism will register the proper amount passing through the pump-in other words, the amount discharged from the pump.

By numerous experiments I have found that I can accurately register by the apparatus shown and described the amount discharged by the pump, and I can so regulate the gearing that a certain number of turns will be equivalent to a pint of molasses discharged, and this number multiplied will give the quarts and gallons, so that it will be seen that a retail grocer, for whose use this pump is mainly intended, can readily measure into any suitable vessel any quantity of molasses without having to first prime the pump or to provide a suitable measuring vessel to receive the molasses from the pump.

By arranging the pumping elements at the lower end ofthe stem I dispense with the need of priming the stem of the pump, and by locating the measuring elements at the upper end I keep them clear of the molasses, preventing clogging and insuring accurate measurement.
