LIQUID-MEASURING DEVICE.

SPECIFICATION forming part of Letters Patent N o. 690,936, dated January 14, 1 902.

Application lcd April 3, 1901. Serial No. 54.164. iNo model.)

To @ZZ whom, it may concern:

Be it known that I, CHARLES DYER, a citizen of the United States, residing at Osage City, in the county of Osage and State of Kansas, have invented certain new and useful Improvements in Liquid-Measuring Devices; and I 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 liquid-measuring devices, and has special reference to an improved device of this character designed for use in measuring liquids of certain specific gravity in vais, cans, or in tanks of uniform diameter.

In its general use the invention is particularly designed as an automat-ic milk-weigher to provide for automatically and accurately giving the correct weight in pounds of milk in a can or vessel, usually in the eight and ten gallon cans, which are ofV uniform shape and diameter.

To this end the invention contemplates a portable liquid-measuring device which is separate and apart from the can or vessel in connection with which it may be employed, so that the same may be readily inserted in and removed from the vessel without having any attachment or connection thereto.

With these and many other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts herein-V after more fully described, illustrated, and claimed.

rIhe structural features of the device are necessarily susceptible to a variety of modiiications without departing from the spirit or scope of the invention; but the preferred embodiment of the latter is shown in the accompanying drawings, in whichm Figure l is a perspective view showing the applied position of the device within a milkcan. Fig. 2 is a detail in perspective of the device. Fig. is a cross-sectional view thereof.

Like numerals of reference designate corresponding parts in each of the figures of the drawings.

In carrying out the invention in the construction thereof the device as an entirety is carried by a supporting-standard l, which is of'suificient length to reach to the bottom of a can or other Vessel of a given size in connection with which the same may be ernployed, and the. said supporting-standard, though susceptible to being formed of different material and constructed in different ways, may be conveniently made of' a suitable length of sheet metal, having the longitudin al side edges thereof folded inward at one side of the sheet-metal strip to form the inturned guiding-flanges 2, the adjacent edges of which are spaced apart to leave a longitudinal slot 3 at the front side of the standard. The construction described provides a supporting-standard with a longitudinal guide- Way extending the full length thereof and slidably receiving therein a sliding indicatorstem 4.

The sliding indicator-stem is preferably constructed of a single length of sheet metal of awidth permitting the same to loosely engage within the guideway of the supportingstandard, and in the preferable construction of the stem the sheet-metal strip constituting the same is formed with a central longitudinal fold 5, offset from one side of the stem and producing a longitudinal reinforcing rib, which stiifens and strengthens the entire stem and at the saine time projects through the slot 3 at the front side of the standard, and thereby assists in properly guiding the slidable stem as the same moves within the guideway of the standard. The said sliding indicator-stem 4 has rigidly fitted to the lower end thereof a float 6, preferably consisting of a hollow liquid and air tight disk, which is offset from the lower extremity of the rib 5, so as to be held for movement in front of the standard l.

An important feature of the invention resides in providing the sliding indicator-stem 4 with a graduated indicator-scale 7. This scale is arranged for cans or vessels of a given diameter and will accurately weigh any quantity of liquid in a can of a given diameter after a given number of pounds in such can have been taken as a standard. lith the graduations once accurately placed upon the stem 4.- the same will necessarily accurately indicate the weight in pounds of any amount IOO of liquid in cans or vessels of the same diameter.

The measurement is obtained by placing the device in a can or other Vessel, and as the milk or other liquid Hows in the iloat G will rise with the surface of the liquid, thereby elevating the stein and registering the Weight of liquid in pounds at the upper end of the standard.

From the foregoing it is thought that the construction, use, and many advantages of the herein-described device will be readily apparent without further description, and it Will be understood that changes in the forni, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A liquid-measuring device of the class described comprising a portable standard whose lower lend constitutes the rest for tho senese device and which is provided at one side With a longitudinal guideway, an indicator-stem of a size substantially equaling the guideway and slidably registering in the latter, said stem having graduations disposed solely at the upper end of the standard, and a float having a rigid connection with the indicatorstern and working Wholly at one side of the standard.

2. A liquid-measuring device of the class described, comprising a standard having at one side thereof inturned guiding-flanges, a graduated sliding indicatorstem Working Within the guideway formed by said flanges, said stem having an offset rib lying between said flanges, and a float carried by the lower end of the stein. y

In testimony whereof I afiix my signature in presence of two witnesses.

CHARLES DYER.
