IMPROVEMENT IN FLUID-MEASURES AND PUMPS COMBINED.

Specification forming part of Letters Patent No. 1179,096, dated June '27, 1876; application tiled f May 3, 1876.

To all whom Iit may concern:

Be it' known that we, WM. H. GLARKand WM. J. CLARK, of Salem, in the county of Columbiana and State of Chio, have invented certain new and useful Improvements in Fluid- Measures and Pumps Combined; and we do hereby declare that the following is a full and complete description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figures l and 2 are side views of the apparatus. Fig. 3 is a transverse vertical section.

Like letters of reference refer to like parts in the seyeral views.

The above said invention is a pump for drawing oil and other liquids from barrels, tanks, and other vessels, and operating in connection therewith is a measuring device, whereby any certain fractional amount of the contents of the barrel may be obtained without the use of ordinary measures for that purpose. For a more full and complete understanding of the invention reference will be had to the following detailed description.

The pump alluded to consists of the barrel or tube A, Fig. 3, of which B is the pumprod; C, the valve attached thereto, and operated from the outside by a button, D. In the lower end of the pump barrel or tube A is a stationary valve, E, all of which are constructed and operated as an ordinary lifting-pump, or may be.

The pump-barrel A is fitted telescopically l in a tube, F, so that it can be extended therefrom 01 drawn therein as the depth of the barrel or other vessel may require, in order that it may reach the contents, while by means of this device the head or measuring apparatus remaips at a convenient height for operating it.

The tube F Vreferred to passes through the center of a receiver, G, and is secured to the top of the inside thereof, by soldering or otherwise, immediately under the stuffing-box H, Fig. 3, whereby the pump-rod is made tight. The tube is secured in vthe bottom of the receiver by a stufng box, I, into which is screwed a follower, J. It will be observed, 011 examination of Fig. 3, that the tube is smaller than the diameter of the follower through which it passes; hence, to enlarge it, so that it may till the follower, or nearly so, lugs aare secured to the side of the tube, which project so far as to reach to the sides of an overby suspension-rods Q, substantially as shown in the drawings.

The gage-tube K may be moved up or down to obtain the required adjustment for measuring any desired quantity, either with the hand or by means of a screw or other well-known mechanical appliances, among which the rack and pinion M N, as shown, a'ord a cheap and quick-acting device.

The gage-tube K, with its means of adjustment, or their equivalents, as described, viz: the stuffing-box I and follower J, collar L and rods Q, rack and pinion M F, may also be attached to and used to regulate the capacity of elevated tanks or other vessels Vindependently of any pumping device. When used, however, in combination with a pump barrel or tube, F, we prefer to have the gage-tube surround the pump-barrel, as shown, in order that greater compactness in the device may be secured thereby. A

Having described the construction and arrangement of the apparatus, the operation of the same is as follows: The pump-barrel A F 1s extended to its full length and inserted in the tank or other vessel until the lower end of Athe pump-barrel reaches the bottom, when by a downward pressure upon the receiver or upper section of the device the tube A is telescoped into the tube F, and the pump-barrel shortened thereby until the collar R rests in the bung-hole of the vessel, (or the support provided for it,) and the receiver is thus brought within convenient distance for operating it; or the pun'ip-barrel may be adjusted before placing it into the vessel to the proper length for withdrawing the uid without disturbing the sediment that may have collected in the bottom. The gage-tube K should then be adjusted by means of the rack and pinion M N, (or their equivalents, as described.) and a graduated scale, d, so as to limit the capaci-v ty of the receiver to the fractional part required to be Withdrawn from the contents ot' the vessel. The iiuid is then pumped into the receiver through the openings c, Figs. 2 and 3, in the upper end ot' the tube F, until the receiver is illed to a level with the top of the gage-tube K. The surplus arising from careless pumping Will ow over the end of the gage-tube and run back into the vessel from which the fluid is being Withdrawn, leaving in the receiver only the quantity for which the gage-tube has been specially adjusted. The

fluid thus measured may then be drawn off inl to the vessel to be filled by means of a faucet, A. When the gagetube is used in combination with an elevated tank or vessel (Whether directly connected with a pump, as shown, or entirely independent thereof) it 'may be adjusted to restrict its capacity to a desired quantity, or the upper end oi' the tube may be raised to the top of the vessel and the latter tilled full, when by lowering the gage-tube any desired quantity maybe dra-Wn oli' through it into other vessels requiring to be filled.

Vhat We claim as our invention, and desire Witnesses:

LUGIEN L. GILBERT, AR. J. THOMSON.
