SPECIFICATION forming part of Letters Patent No. 286,331, dated October 9, 1883.

Application mea May 23, ross. (No model.)

To @ZZ whom, it may concern:

Be it known that I, BENJAMIN C. RICHARD- SON, of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Milk-Coolers; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form apart oi this specification, and in which-- Figure l is a vertical section of my improved crea-ming-can. Fig. 2is a perspective view of the refrigerati-ing attachment removed from the milk-can, and Fig. 3 is a vertical section of a modification of my invention.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to that class of milk-coolers in which the 'ice-receptacle is placed inside of the milk-can;r and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, A represents the body of the milk-can, inside of which rangement I keep the ice dry, so that it will the refrigerating attachment is placed. The can is provided at its upper part, near the neck, with two or more air-tubes, B B, for allowing the animal heat 'and gases arising from the milk to' escape from the can, the outer ends of the air-tubes being covered by screwthreaded caps B. A numberof holes (shown at b) are pierced through the sides of the screwcaps and the sides of the air-tubes, so that by turning the screw-threaded caps vuntil the holes b in the caps and the holes c in the airtubes register the animal heat and. gases arising from the milk may escape from the can without removing the caps entirely from the air-tubes.

C is the ice-chamber ofthe removable cooling attachment, and is connected by three or more tubes, D D D, to the drip-pan E. As the ice in the chamber C gradually melts, the water runs down through the tubes D vinto the drip-pan E, where it is collected. By this arlast twice as long as it would ifthe water were allowed to remain in the same chamber with the ice. LBy constructing the cooling attachy ment-in the manner described, I succeed in cooling the milk in an exceedingly short period of time. A cone-shaped stud, F, is attached to the inner surface of the bottom of the milk-can, and fits into a conical recess, F', in the bottom of the drip-pan, thereby holding the lower part of the cooling attachment iirmly in position. The cover of the milkcan. has an annular metal strip or ilange, G, soldered or otherwise fastened to the inner surface of the cover, so that when the cover is placed upon the can the annular strip or flange G will fit tightly between` the outer surface of the ice-chamber and the neck of the can, which arrangement, together with the cone-shaped stud F, fitting into the conicall recess inthe bottoni of the drip -pan, will serve to hold-the cooling attachment iirmly in position and prevent any displacement of the said cooler when the can is being roughly handled. On the outside of the ice-chamber, near its top, are two lugs or projecting pins, H H, adapted to fit into slots I I in the annular strip G. vlll-Then lit is desired to remove the cooling attachment from the can, the cover is turnedvor rotated to thelcft, when the lugs or proj ecting pins H H will enter the slots I I in the annular strip G, when the cooling attachment can be lifted out of the can by the handle of the cover.

Ii' desired, a small tube, J, may be inserted into thev bottom of the drip-pan, the free end of the said tube passing through an opening in the bottom of the can, said opening being provided with a washer of suitable material,

in order to make the opening water-tight when the tube J is passed through it. of the tube J is closed by a screw-threaded cap, J so that by removing the said cap the water in the drip-pan can be drawn offwithout removing the cooling attachment from the pan. The above construction is clearly illustrated in Fig. 3 of the drawings. When the tube J is used with my improved 'milk-cooler,

thelower rim of the can, on which the weight` of the can rests, is made of a sufficient depth to keep the screw-cap on the tube from coming in contact with the ground.

From the foregoing description, taken in connection with the accompanying drawings, the construction of my improved milk-cooler will readily be understood. without requiring The free end I IOO extended explanation. It will be seen that my improved milk-cooler is simple in construction, and is very convenient to handle in removing the Water from the cooler. .e

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- Y In a milla-cooler, the combination of the receptacle A, provided with suitably-constructed vent-tubes and caps covering the same, coni-y caln'stud or projection F, located centrally in the bottom of the can, removable refrigerating attachment composed of the ice-receptacle C, drain-tubes D,' and closed drip-pan E, having conicall recess F', adapted to t the stud F, 1`5 vand cover having a downwardly-projecting iiange, G, adapted to iit between the outside of the ice-receptacle and the neck of the can, the f whole constructed and combined substantially as and for the purpose shown and described.

In testimony that I claim the foregoingas my oWn I have hereunto affixed my signature in presence of two Witnesses.

BENJAMIN CLARK RICHARDSO.
