UNITED STATES PATENT OFFICE.
SYLVANUS F. BOWSER AND AUGUSTUS BOWVSER, OF FORT IVAYNE, INDIANA.
MEASURING-PUMP.
SPECIFICATION forming part of Letters Patent No. 480,551, dated August 9, 1892.
Application filed May 2, 1892. Serial No. 431.417. (No model.)
T0 all whom it may concern:
.States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and usefullmprovements in Measuring-Pumps, (Case 0;) and we 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.
This invention relates to measuring-instruments, and especially to that class thereof known as measuring-pumps, and the object of the same is to effect certain improvements in the gaging mechanism for controlling the amount of liquid which the pump This object is attained by constructing said mechanism substantially as hereinafter more fully described, as well as by applying an index-hand for indicating the position of the mechanism, all as claimed below and as illustrated in the accompanying drawings, wherein- Figure 1. is a vertical section of a tank and pump, showing our improved gaging and indicating mechanism as applied thereto. Fig. 2 is a plan viewof a portion of the top of the tank, showing the indicator in. one position, and Fig. 3 shows it in the opposite position. Fig. 4 is a vertical section showing a modith cation of the construction illustrated in Fig. 1. Figs. 5 and 6 are plan views of the top of the tank, similar to Figs. 2 and 3, showing the index as used with the construction of Fig. 4. Fig. 7 shows an enlarged elevation and section of the gage-tube hereinafter described.
In United States Letters Patent No. 37 2,250, granted to us on October. 25, 1887, we employed an oscillatory stop-rod in connection with a plurality of stops thereon and a single collar on the pump-rod. Prior to that patent devices had been patented employing oscillatory pump-rods having radial stops adapted to pass through holes in the tank-covers or to strike beneath said covers. In an application filed by us of even date herewith, Serial No. 431,416, we illustrate and describea swinging gage-rod carrying the stops and holes in the top of the tank. The present invention differs from all these in' that it employsa tubular gage surrounding the pump-rod and a stop on the pump-rod adapted to strike the lower end of the tube or to pass up into a slot therein, according as the rod and tube are turned relatively to each other.
Referring now to the accompanying drawings, the letter N designates aportion of a tank of any approved pattern and within which is located a pump-cylinder W, communicating with the tank through an upwardly-opening valve V.
b is the solid head of the pump, and J is the delivery-spout.
F is the pump-rod passing up through the top 0 of the tank, and K is a handle on this rod, the construction being substantially the same as in the patent and application above referred to and the operation such that when the pump-rod F is forced down the liquid is expelled or forced upward through and out of the delivery-spout J, all as will be clear.
Coming now to the present invention, the letter D designates a gage-tube, whose upper end is annularly and exteriorly grooved, as at d. This end fits within a depending collar 0 of the top 0 of the tank, and a set-screw dpasses through said collar and rests in the groove, whereby the tube may turn, but cannot move vertically in the collar. Any other suitable means may, however, be employed for forming this connection so long as the result is the same.
In one side of the tube D is a slot E, Fig. 7, open at its lower end F, where it flares slightly. At the upper end of this slot We preferably secure an angle-iron 19, through which takes a downwardly-facing set-screw q, and to the side of the tube we also preferably secure another angle-iron r by means of a set-screw 8 taking through a slot in the iron and into the tube, as seen. These angle irons and set-screws may, however, be omitted, if desired; but we prefer their use as permitting the fine adjustment of the liquid to be measured, all as will appear hereinafter. The pump-rod F passes centrally and longitudinally through the tube D, and it carries a stop or lug I, which is adapted to strike the lower end of the tube tor the angle-iron there) or to pass up into the slot E and strike its upper end, (or the angle-iron there.) In Fig. 1 we have shown an index or pointer L secured to the upper end of the tube and moving over a scale M on the top Ofrom l to2. Vhen this index stands at 1, the lower end of the tube (or its angle-iron) is in the path of the stop I, and hence the rod can be raised hole H in a cross-bar G, mounted on the top of the pump-cylinder.
In Fig. 4 a slight modification of this idea is shown. In this case the rod F is round and the cross-bar G omitted, so that the rod may turn, the index L being secured upon the rod by the set-screw i, so as to turn therewith, while the tube D is stationary in the top 0'. The operation is the same, except that the index will rise and fall with the pump-rod.
In operation the tank is filled with the liquid to be measured and the cover applied. Vhen it is desired to draw one charge, (say one quart,) the index is set at the point which indicates that size of charge, the handle K grasped and raised, and then depressed, when the charge will flow from the spout J, which has previously been pumped full, as will be clear. If it is desired to measure out two charges, the index is set at 2 or 2 and the same operation gone through with, when the two charges will flow from the spout. If the an gle-irons and set-screws are employed, it will be obvious that the size of the charges may be adjusted to great nicety; but by making the other parts of proper relative sizes and shapes this may be avoided. However,we reserve the right to use them, if found desirable. Other changes may also be made in the construction without departing from the spirit of our invention.
We lay no claim herein to anything shown in our previously-issued patent, nor to the subject-matter of the application above referred to; but,
Having thus described our invention, what we claim as new is 1. The combination, with a pump having a stop on its pump-rod, of a tube surrounding said rod and having a recess adapted to receive said stop and means, substantially as described, for adjusting the rod and tube relatively, as and for the purpose set forth.
2. The combination, with a reciprocating surrounding the rod, the tube being slotted at its lower end to receive the stop, means, substantially as described, for adjusting the rod and tube relatively and axially to each other, and an index carried by the moving part and operating in conjunction with said scale, as and for the purpose set forth.
4. The combination, with a reciprocating pump having a stop on its rod, of a tube surrounding said rod and having a slot in one side open at its lower end and adapted to receive said stop, an angle-iron secured at the upper end of said slot, a set-screw therethrough, a second set-screw in the side of the tube, and a second angle-iron having a slot taking under the head of this setscrew, all as and for the purpose set forth.
5. The combination,withareciprocatingrod having a stop, of a tube having a slot in which said stop may pass or against whose lower end it may strike, means, substantially as described, for turning the rod and tube relatively and axially, and set-screws and angle irons at the upper end of the slot and at the lower end of the tube, as and for the purpose set forth.
6. In a measuring-pump, the combination, with a tank having a collar depending from its top and a scale marked on said top, atube supported and turning in said collar and having a slot in its lower end, and an index secured to said tube and moving over the scale, of a pump within the tank, having a delivery-spout, the pump-rod passing through said tube, means for preventing the turning of the rod, and a stop secured to said rod, as and for purpose set forth.
7. In a measuring-pump, the combination, with a tank having a collar depending from its top and a scale marked on said top, a setscrew through said collar, a tube swiveled in the collar and having an exterior groove engaged by the tip of said set-screw, the body of the tube being slotted at its lower end, and an index secured to the tube and moving over said scale, of a pump within the tank, having a delivery-spout, the pump-rod passing through the tube, means for preventing the turning of said rod, and a stop on the rod, as and for the purpose set forth.
8. In a measuring-pump, the combination, with a tank having a scale marked on its top, a tube swiveled in said top and having a slot in its lower end, and an index secured to the tube and moving over said scale, of a pump within the tank, having an angular pump-rod moving through said tube, a stop on said rod, and a cross-bar on the pump-cylinder, having a hole closely fitting saidv rod, all as and for the purpose hereinbefore set forth.
In testimony whereof we afiix our signatures in presence of two witnesses.
