LORENZ A. DEUTHER, OF BUFFALO, YORK.

ICE-CREAM CARRl ER.

SPECIFICATION forming part of Letters Patent No. 593,322, dated November 9, 1897. Application filed November 11, 1895. Serial No. 568,588. (No model.)

To all whom it may concern.-

Be it known that I, LORENZ A. DEUTHER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Ice-Cream Oarriers,of which the following is a specification.

The object of my invention is to produce a simple and cheaply-constructed ice-cream carrier whereby ice-cream may be carried a long distance or kept a comparativley long time without injury, and it will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which Figure 1 represents a perspective view of my improved ice-cream carrier. Fig. 2 represents a vertical central section on or about line a a, Fig. 4. Fig. 3 is a central sectional elevation showing the manner of securing the cover in place. Fig. 4: represents a horizontal section on or about line b b, Fig. 2. Fig. 5 is an inverted perspective view of the cover.

Referring to the drawings in detail, the outside portion or shell of the body is designated by the numeral 1. It is in the form of a cylindrical shell. At the top and bottom separating- rings 2 and 2 are securely cemented to the top and bottom of said shell. Inside of the rings 2 and 2 is secured by cement or in any well-known way an interior cylindrical shell 3, thereby leaving a non-conducting air-space 4 between the inner and outer shells.

It is preferable to form the outer case of two cylinders, one'within the other, substantially as above described, as by this means the heat is not only prevented from reaching the refrigerating material, causing it to melt faster, but the cold is prevented from coating the outer surface with condensed moisture and thus presenting a disagreeable chilly wet exterior. It also greatly strengthens the cylindrical shell and renders the whole structure more substantial and durable. Within the inner shell are secured the end pieces 5 and 6, each secured in place by cement or other well-known means. In the top end pieces 6 is a square opening in which is secured a pendent rectangular box 7. This box is preferably made square in cross-section and extends down'into the receptacle to within a short distance of the opposite end 5, leaving room in which to place the surrounding refrigerating material, as will more clearly appear farther on. The end portion 6 is provided at each side the square opening, into which the box 7, with an angular slip of metal 8, (see Fig. 3,) fits. These pieces of metal are either secured between the two thicknesses of material, as shown, or they may be riveted thereto. Their office is to provide'a convenient means for securing or fastening the cover in its place. The cover 9 is square and provided with a series of flat separated portions 10, thereby leaving air-spaces 11 between them. The separated square portions 10 are made just large enough and of a shape corresponding to the receptacle 7, so as to enter and fit nicely therein, the cover 9 resting on top. The metallic slips 8, which are in the position shown in Fig. 3, are then bent over on the cover, substantially as shown in Figs-.' 1 and 2, thereby securing it thereto. At the end 5 is a round opening in which is removably secured in the ordinary way a stopper or cork 12. (Shown in Fig. 2.) The separate parts of the cover are secured together by means of a metallic slip 1O or an ordinary fiat-head fastener which is passed down through the several parts and the ends then turned over, substantially as shown in Figs. 2, 3, and 5. By referring to Figs. 2 and 3 it will be observedthat the strips separating the flat portions 10 decrease in size from the top portion 9 downward. This locates the largest air-space nearest the cream. Each flat portion is increased in stiifness from the bottom upward by the increase in size of the central separating-strips, and the joints between the edges of the fiat I portions and interior of the cream-holder are thereby increased in firmness, tightness, and closeness from the bottom upward.

When using this device, the cork or stopper 12 is removed and broken ice and salt, if required, are put in through the opening, which is then secured by the cork or stopper 12. The ice-cream isthen put into the box 7. The cover is then put in place, so that the pieces 10 pass in, and the cover 9 rests on the top 6. The ends 8 of the metal fastening shown in Fig. 3 are then bent over onto the cover, substantially as shown in Figs. 1 and Ioof 2, thereby securing it firmly in place. In this condition ice-cream can be kept for a long time without melting. The air in the surrounding space 4 acts as a non-conductor and tends to protect the ice from the outside heat.

The air-spaces 11 also act as non-conductors of heat.

When it is desired to remove the ice-cream, all that is necessary to do is to bend or turn up the parts ,8 and remove the cover. The receptacle is then turned over to one side far enough to allow the block of cream to slide out into a proper receptacle. I

This device is constructed of waterproof paper as the cheapest and best material for the purpose and may be made waterproof in any well-known way.

It will be noticed by reference'to Fig. 2 that when the protecting-cover 9 is secured in place substantially as shown in that figure the lower portion of the said cover projects vinto the mouth of the ice-cream receptacle sufficiently to allow the refrigerating material to cool the air-spaces in the said cover.

By forming the cover in the novel manner described I not only eifectually protect the mouth of the compartment, but also provide a series of air-spaces formed by the inner wall of the compartment and the separated fiat portions of the cover.

As the fiat portions of the cover are made so. as to fit tightly in the mouth of the icecream compartment, the flexible springy character of the waterproof paper composing the said portions causes them to form a tight joint. By this method the cream is protected on all sides and the same even temperature exists in all portions of the same.

It will also be perceived by reference to Fig. 2: that the cover 9 and the stopper 12 are substantially fiush,or nearly so,with the ends of the device, their outer faces being raised but a very slight distance above the ends of the outer protectin g-case when they are seated in the openings in the said ends that they are adapted to fit and seal. The device can therefore be very easily wrapped or done up in paper, as there are no projecting portions to interfere with or hinder the operation or break through the papers.

What. I claim, and desire to secure by Letters Patent, is

1., A cover formed of waterproofed paper, and composed of a series of flat layers separated from each other at or near their centers by separating-strips, each of said strips beinglarger than its adjacent preceding strips from the bottom upward, and fastening devices for securing the said cover portions together, as set forth.

2. In anice-cream carrier, the combination with the creanrholding compartment hung pendent from one end of the cylindrical pro- 5 tecting-case, and provided with an open Z mouth, of a cover comprising an outer flat portion larger than the said mouth, and a series of fiat portions separated from each other by separating-strips and of a size and shape adapted to fit tightly in said mouth, and there by form confined air-spaces between the outer fiat portion and the interior of the creamholding compartment when the said cover isseated in said mouth, as set forth.v

3. An ice cream carrier, comprising an outer protecting-case formed of two cylinders, one slightly larger and within the other, circular separatin g-rin gs interposed between the said cylinders at the top and bottom thereof, end pieces composed of two portions fitting closely in the bottom and top of the said inner cylinder of the protecting-case, an open-t ing in the bottom end piece, a stopper for. closing the same, an opening in the top end piece, an ice-cream holder provided with an open top end and hung pendent in the pro tecting-case, the edge of the upper end of the cream-holder being secured to the edge surrounding the opening in the top end of the protecting-case, a cover composed of flat portions separated from each other by interp0sed strips, said fiat portions fitting closely in the open top end of the cream-holder, an outer top portion larger than the separated flat pertions and projecting over the surrounding edge of the said open top end,.a fastening device passing through the said top portion, the

separated fiat portions and the interposedstrips, and metallic slips having one end w cured between the two parts of the top end of the protecting-case and the other bent over the outer top portion of the cover to secure it in place, as set forth.

4. Aportable ice-cream carrier, consisting of a cylindrical box provided at one end with j a square opening through which is introduced and rigidly secured a rectangular ice-cream receptacle adapted to receive a hard frozen brick of ice-cream of substantially the same form and shape as the said receptacle, a cover consisting of flat portions separated from each other at or near their centers by separatingstrips, a fastening device for securing them together, metallic slips for fastening the said cover in its place, an opening at the opposite end of the said cylindrical box, for the introduction of refrigerating material and a stopper for the same, the rectangular receptacle being so arranged in the cylindrical box that the refrigerating material can be placed equally on all sides thereof except the top and as the top cover is formed of several separated layers and projects down a short distance into the ice-cream receptacle, all portions of the cream are kept at the same equal I temperature, as set forth.
