IMPROVEMENT IN ADJUSTABLE MEASURES.

Specification forming part of Letters Patent No. 58,838, dated October 16, 1866.

To all whom it may concern:

Be it known that I, HENRY KRAUT, of St. Louis, county of St. Louis, in the State of Missouri, have invented a new and Improved Mode of Constructing Adjustable Measures; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the combination of a receiving'cylinder, O, and a hollow measuring-piston, A, either of them movable and adjustable, so that by the draw ing out of the piston A or lowering of cylinder 0 the space for the substance to be measured can be extended in a desired proportion.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct a metallic or other cylinder, 0, Figures 1, 2, 4-, 5, with a fumielshaped end provided with an outlet valve or cock, (I. I insert in the same a hollow piston, A, provided on its top with an inlet-slide, c, Fig. 1, or cock 0, Fig. 2, and at the lower end with an extension, a, which closely fits the cylinder 0, and which, in those of my apparatus wherewith liquids shall be measured, is provided with any of the known tight packings. The inletslide 0, Fig. 1, or cock 0, Fig. 2, are opened and closed in any of the already known manners.

I further provide the receiving-cylinder C with an apparatus for lowering and raising, ft, with ropes or chains passing over rollers ff to a notch-wheel, g, Fig. l, or by means of a sliding coulisse, h, on an upright shaft, m, Fig. 5, to which, for producing an exact measure, an adjusting-screw, a, may be attached.

The application of my invention is as follows, to wit: The measuring-piston A, when resting with its lower end on valve or cock (1, contains a certain quantitysa-y, for instance,

one bushel of grain or five gallons of liquid substance. I shut the exit valve or cock at and open the inlet slide or cock 0, whereupon the grain or liquid will run into and fill up the space inside of the piston A. When filled I shut up the inlet slide or cock- 0 and open the exit valve or cock (I, whereupon the contents of the piston A will empty into the receptacles kept ready for filling.

If two bushels of grain or ten gallons of liquid shall be measured with the same apparatus, I lower the cylinder 1) in a manner, as stated above, so that between valve or cook d and the lower end of piston A there is a room left which will hold exactly one bushel or five gallons, as the case may be. If the apparatus is arranged in that way I can measure every time exactly two bushels or ten gallons at once. By further lowering the cylinder 0, I can increase the room for the quantity to be measured at once.

It is obvious that scales have to be provided showing the exact position of the receivingcylinder when containing the quantities to be measured, as will be seen in Fig. 4 and Fig. 5.

The advantages of my adjustable measures over the old telescopic measures are that a smaller space is needed for the same; that they can be adjusted quicker and with the utmost accuracy, and that by few movements several measures can be adjusted at the same time.

I claim as my invention and desire to secure by Letters Patent The combination of the movable and adj ustable receiviugcylinder O and hollow measurin g-piston A.
