SPECIFICATION forming part of Letters Pate t No. 547,656, dated October 8, 1895.

Application filed Me. 14, 1295.

To aZZ whom, it may concern;

Be it known that I, ALFRED L. BARON, of Tiffin, county of Seneca, State of Ohio, have invented certain new and useful Improvements in Can-Guards, of which the following is a specification, reference being had to the accompanying drawings.

The object of my invention is to produce improvements in cans or vessels for containing liquids, by which the cost of manufacture of the guarded can is diminished and its durability and compactness are increased, and also in coverings for cans by which the fragile material, usually of glass, of which the cans are made, is effectually protected against damage or injury from outside blows orshocks.

In the accompanying drawings, Figure I is a side elevation of my can. Fig. II is a cen- Fig. III is a bottom plan view thereof; and Fig. IV is a view of the lateral jacket detached, showing the means of forming the base or bottom part thereof.

Referring to the figures on the drawings, 1 indicates a can-body, which may be made of suitable shape, size, and material, usually glass.

2 indicates the head, preferably made of tin or other sheet metal and provided with a spout 3 and a screw-cap 4.. It is provided with a flange 5 surrounding a collar 6 of the canbody, to which it may be secured by suitable means-as, for example, plaster-of-paris. The periphery of the head is preferably screwthreaded, as indicated at 7, to receive and hold the flanged internally screw-threaded annulus 8, of which 9 indicates the flange.

10 indicates the jacket, which is preferably made of interwoven spring-wire, preferably consisting of aseries of interwoven springwire spirals 11.

In practice a cylindrical jacket of the material is manufactured to fit the size of the can to be protected, as illustrated in Fig. IV. It maybe made by the well-known machine for weavingbed-mattresses, where interwoven spirals are employed; but any suitable method of manufacture may be substituted therefor. When the cylinder is completed, the bottom part maybe formed by placing it over an Serial No. 541,771. (No model.)

7 iron cylinder 12. (Illustrated by dotted lines in Fig. IV of the drawings.) This cylinder corresponds in shape and size to the can for which the cylinder or jacket is designed to be fitted. A die (indicated by dotted lines and designated at 13 in Fig. IV of the drawings) is forced against the end of the iron cylinder, so as to compress'the end of the jacket and to mash the spirals thereof, thereby causing them to lie nearly at right angles to the side walls of the jacket after it is lifted from the iron-cylinder, as indicated by 14 in the drawings. It is then placed over the glass can or vessel, the inturned edges 15 forming the bottom protection for the same. Afterward the upper part of the jacket is gathered by suitable meansas, for example, a temporary confining-annulus, (notillustrated)-until the edges approach the periphery of the head 2. The annulus 8 is then screwed in place, its flange 9 serving to permanently confine the upper end of the jacket in place. When this has been accomplished, the an nulus8 may be secured in position, as by soldering, the tem porary annulus being no longer necessary, and the can properis completed. Inasmuch, however, as the raw edges 15 of the can-jacket are exposed and unless great care be exercised in the manufacture of the jacket they may tend to catch upon an obstruction with which they may come in contact, I prefer to employ thebottom peripheral bends or spirals 17 as spring cushions or yielding support for a plate-metal bottom 18. The bottom 19 of the glass receptacle is preferably concave, and the plate-metal bottom is also similarly formed so as to give a smooth, level bearing or supporting surface 20 around its lower periphery, its edge being turned up to constitute an annular groove for the reception of the convolutions of the jacket and thereby bringing the upper edge of the bottom plate substantially in line with the bottom of the can-body to form a neatfinish and to, prevent the lower convolutions of the jacket from coming in contact with the adjacent surfaces when the can is slightly tilted upon its edge. The platemetal bottom may be secured to the springcushions in 'a variety of ways; but I prefer to employ for this purpose a wire frame21, bent to span and conform to the contour of the bottom of the can-body, as indicated at 22, and thence passing upwardly through diametrically-opposite spirals 23 in the jacket, termi- 5 mating in eyelets 24: near the upper end of the jacket. An indented diametrical groove 25 in the bottom of the bottom plate serves by engagement with the frame not only to hold the bottom plate in position, but also embeds [0 the material of the frame 21, so as to protect it against striking any obstruction with which it ordinarily may come in contact. arrangement a convenient means of rigidly fastening the frame 21 in place may be conveniently provided. As additional means of seeming the frame 21, I prefer to employ radial loops 27, secured, as by soldering or otherwise, under the flange 0, through which the eyelets may be passed, the eyelets being free to slip through the loops when the parts are assembled. The engagementof the eyelets with the bends of the loops tends to hold the frame 21 in place, but an effective and reliable union of the frame with the loops may 25 be insured by inserting the eyelets 2S ofthe bail-piece 29 through the eyelets 24 at right angles to them, the eyelets 28 being in practice of sufficient size to lock the eyelets 24 in position within the loops.

A simple and convenient form of tilting handle consists of a wire frame 29, having its ends 30 bent at right angles to the frame and inserted through the meshes of the jacket before it is placed upon the can. After itis 5 in position upon the can it is firmly held in place by the pressure of the interiorwall of the jacket against the exterior wall of the can-body.

\Vhat I claim is- 1. The combination with a can body, abettom plate and intermediate yielding spring cushions, of a frame passing underneath the bottom plate, and mechanism upon the under side of the bottom plate co-operating with the 5 frame to hold the same in place, substantially as specified.

2. The combination with a can body, abottom plate and intermediate yielding spring cushions, of a frame passing underneath the bottom plate, and a groove in said bottom plate for the reception of said frame, substantially as specified.

3. The combination with a can body, of a concave bottom plate having its outer periph- 5 ery upturned to form an annular groove or seat, an intermediate cushion between the bottom of the can body and the bottom plate consisting of inter-woven springwire spirals, the convolutions of which adjacent to thepe- 6o riphery of the can body bottom being seated in the annular seat of the bottom plate, and means for securing the bottom plate to the can body, substantially as specified.

4. The combination with a can body, jacket composed of spring wire spirals, and cushions By this therein upon the bottom of the can body, of a bottom plate, a diametrical groove therein, a wire frame embedded in the groove and extending upwardly through opposite spirals in the jacket, and means for securing the wire frame in place, substantially as set forth.

5. The combination with a can body, jacket composed of interwoven spring wire spirals, and cushions below the can body, of a bottom plate, frame supporting the bottom plate, and a top jacket confining part confining the upper end of the jacket and supporting the frame, substantially as specified.
