REFRiIGERTING-COVEB EOE MILK-(JANS.

Specification 'of Letters Patent.

Patenten May 2e, 1914.

Application filed December 24, 1912. 'Serial No. 738,472.

To all whom it may concern Be it known that I, SAMUEL SHArIRO, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Retrigerating-Covers for Milk-Cans, of which y the following is a specification.

y ticles of dirt and foreign matter coming into Contact with the can cover, so that when the cover is opened, there is no danger of 'the dirt falling into the milk.

A'further object is to provide a `cover of' this character which may be manufactured and sold at an extremely low price, which may be quickly applied to a `milk can, and which will most eciently perform the functions for which it is intended.

With these and other objects in view, the

'invention consists in certain novel features of construction and. combinations and arrangements of parts as will be moreffully hereinafter described and pointed out in the claim.

In the accompanying drawings: Figure 1 is a view in elevation partly broken away l illustrating my improvements- Fig. 2 is a view in longitudinal section through the cover, and Fig. 3 is a fragmentary view in section on an enlarged scale on the line H of Fig. 1.

1 represents an ordinary milk can, 2 the neck, and 3 the cover. Cans of this character are ordinarily formed with an annular bead 4 Wherethe upper portion of the can -joins the bead of the can, and this bead is located usually above the handles 5.

While I have illustrated my improved cover in connection with a can of this character, it is of courseto be understood that it is adapted for use on any ordinary lmilk can, but the bead lif'serves a very useful'purpose in connection with my cover as will be hereinafter explained. l Y Myimpr'oved cover 6' is tubular in form, open at both ends, andA composed of some its binding rope, the ice will liexible material, for example, heavy canvas. Around the lower end of the cover, a strap 7. is secured by lines of, stitching 8. rIhese lines of, stitching terminateshort of .the free ends of the strap, and a buckle 9 is provided which connects the ends of the strap. By thusl terminating the stitching short of the ends of the strap, when the ends of the'strap are drawn tight by means of the buckle, the,`main portion of the lower end of the cover -will lle smooth, and only that portion under the buckley will be wrinkled. This allows suiiicient slack in the cover to permit it to be readily positioned on the can l with the strap portion 7 below the bead 4, and when the strap is secured tight by means of the buckle, the cover will be rmly held to the can under the bead and constitute a closure for the lower end of the cover. This also prevents any possibility. of the cover being drawn off the can, While 1n use.

The upper end of the coverG is hemmed as shown at 10, the hem inclosing a rope 11 so that this 'upper edge of the cover is reinforced by means of the rope ll. A binding rope 12 is secured near one end to the cover as' shown at 13, and this binding rope is adapted to be wound around the cover when the latter is collapsed at the top land securely tied. The rope 11 insures an enlargement at the upper end of the cover, so that the `binding rope 12\ cannot slip over the end of the cover. The rope 11 also 'reinforces the cover and strengthens the same for its ordinary use.

In operation, the cover is positioned on the can and the strap 7'securely held in the buckle 9. Ice illustrated at 14 is then positioned in the coverand entirely surrounds the neck of, the can, is supported at the upper end of the can, and incloses the`cover of the can. When the upper end of the refrigerating cover 6 is secured b means of e confined around this portion of thecan, and will keep the contents of the can cool.

This invention utilizes the well known fact that the warmest part of the milk or cream is at the top and by keeping cool the upper portion of the can, the entire contents are maintained at a low temperature. It will furthermore be noted that the refrigerating cover not only confines they ice about the can, the neck, and the cover, but also excludes dirt .and dust from the milk.

Hence, when the can is opened, there will be no accumulation of dust or dirt thereon to fall into the can, and the refrigerating cover 6 therefore acts as a dirt and germ excluder asv Well as an ice holder.

While l have illustrated 'my improvements in connection with small pieces of ice in the cover, it is of course, to be understood that if desired a large piece of ice may be placed upon the` can cover 3, and the invention is not limited to the particular details set forth, but l consider myself at liberty to make such changes and alterations as fairly fall Within the spirit and scope of the appended claim.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is:

A refrigerating cover for milk cans comprising a tube of flexible material, a strap arranged flat against said tube adjacent yits lower end and secured thereto throughout the entire circumference of the tube with the exception of a relatively small space, and said strap having free ends adapted 'to bridge said relatively small space and to be secured together to clamp the tube around a milk can beneath an annular shoulder thereon, and means for binding together the upper end of said tube, substantially as described.

In testimony whereof I have signedmy name to this specification in the presence of two subscribing Witnesses.
