DEVICE FOR AERATING MILK.

SPECIFICATION forming part of Letters Patent No. 323,069, dated July 28, 1885.

(No model.)

To all whom it may concern.-

Be it known that I, J EPTHA DTA'rTERsoN, a citizen of the United States, residing at Abbotts, in the county of Cattaraugus and State of New York, have invented certain new and useful Improvements in Devices for Aerating Milk; and I do 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to a device for aerating milk; and it consists in the novel construction, combination, and arrangement of the several parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a side view of my device, the cylinder being broken away to show the piston. Fig. 2 is a detail view of the piston. Figs. 3, 4, 5, and 6 are detail views of the piston, all of which will be described.

The cylinder A is open at its upper end, and is contracted at its lower end to form a nipple, a, on which is fitted the air-disshorter than B, so by using first both see I tions, as shown, then removing section 0, and subsequently substituting section 0 for B, I am able to force air into three different strata of the milk. The number of sections may be increased to suit the will of the maker. I have only shown two sections, as they illustrate the spirit of my invention. The tubes being of a small diameter do not practically disturb the cream which may have risen on the milk. The air-piston D operates within the cylinder A, and has the arms (1 extended from the lower end of its rod D. The lower ends of these arms are threaded to receive the nuts cl. The disks E F are provided with perforations slipped over the arms d. Central concentric apertures, e f, are formed through these plates, the former, e, being the smaller, as shown in Fig. 3. A leather or other suitable elastic disk, G, is clamped between these plates by the nut (1 being turned up against the lower plate. I make the disk G of a larger diameter than the disks E F, so it will extend beyond said disks, as clearly shown, and form the packing between the same and the walls of the cylinder. The flap-valve g is out from the center of this leather disk, and is made of a diameter to fit and operate within opening f, and yet large enough to operate over the opening 6, around which the valve sits when closed.

The operation is simple, and will be readily seen. With the downward stroke of the piston the valve closes, and air is forced into the milk. On the upstroke of the piston the valve opens, permitting air to enter the cylinder,and preventing the piston from sucking the milk up, as will be understood.

By making the peripheral packing and the valve of the piston from the same piece of leather, a simple. and cheap construction is provided.

My piston can be easily taken apart for the purpose of cleansing or renewing any of the parts, as will be understood.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

The herein shown and described milk-cooling device, consisting of a cylinder contracted at its lower end to form a nipple and provided with interchangeable pipe-sections of varying lengths, in combination with a piston working in said cylinder, composed of a rod having arm-extensions branching from its lower end, threaded on their outer extremities to receive a pair of concentrically-apertured disks between which is interposed a disk of leather the periphery of which extends be- In testimony whereof Iaffix mysignaturein yond the edges of the disks the three being presence of two witnesses.
