' FOLDING JAR-RACK.

Specification of Letters Patent;

I Application filed May 13, 1918. Serial No. 234,237.

To all whom it may concern:

Be it known that I, HENRY A. HILDRETH, a citizen of the United'States, residing at Boston, in the county of Suffolk and (10mmonwealth of Massachusetts, have invented a new and useful Improvement in Folding J ar-Racks, of which the following, together with the accompanying drawings, is a specification.

The object of my invention is to provide a rack for holding jars in the process of canning fruit or vegetables, which consists of a single piece and is capable of being folded so as to lie flat; Jar-racks have hitherto been proposed capable of being folded, but such racks so far as we are aware are either constructed of two or more pieces, or when folded are so bulky as to be objectionable. The rack forming the subject of my present invention consists of a single piece properly hinged together so that it can be folded into a position in which the sides and handles lie substantially flat with the bottom of the rack, with the handles included within the area of the folded rack thereby taking up but little space, and when carried in stock by the dealer, are capable of being folded into a small compass forming substantially fiat packages which can be stored upon a shelf one above the other.

In the accompanying drawings,

Figure 1 is a side View of my improved jar-rack, showing jars held therein which are represented by dot and dash lines.

Fig. 2 is an end view.

Fig. 3 is a plan view, and

Fig. 1 is a plan view of the folded.

Similar reference characters refer to similar parts in the different figures.

My improved rack comprises a platform or base 1, preferably consisting of a heavy wire rim 2, in the present instance having straight parallel sections 3, 3 and. round ends 4, 4: inclosing an oblong space which is filled with a Woven wire fabric 5. The woven wire fabric supports the jars 6 when placed in the rack in the position shown, represented by dot and dash lines.

Spaced above the base 1 IS a frame 7 corresponding in outline with the base 1, and having straight sections 8 and round ends 9 corresponding in size and shape to the ar-rack when base 1 and forming a framework which is divided by a central longitudinal bar 10 and

transverse bars

11, 11 into compartments, in the present instance eight in num her, in which the jars 6 arerplaced. Hinged to the straight sections of the wires 2, by means of eyes 12, are the upright wires 13 forming sides to the rack which are stiffened by the wires 14:. The frame formed by the wire 7 and the

cross wires

10 and 11 is likewise hinged to the upright wires 13 by. eyes 15. The upright wires 13 extend a short distance below the eyes 12 and are preferably curved at their lower ends at 16 to form feet, which rest upon a table or shelf when the apparatus is in use. The upper ends of the upright wires 13 are provided with eyes 17 in which are pivoted the curved bails 18, capable of swinging toward each other and lying flat upon the frame formed by the wire 7 and the

cross wires

10 and 11. The ends of the base 1 are also provided with legs 19.

In order to simplify the structure and to allow it to be collapsed and to lie flat, I form each of the uprlghts 13 of single short pieces of wire looped at the ends only, as at 16 and 17. The eyes 12 are rigidly attached to the uprights and extend inwardly to inclose the peripheral wire 2 of the base section, and similar eyes 17 are rigidly attached to the uprights 13 and extend inwardly to inclose the peripheral wire of the frame 7. The

eyes

12 and 15 obviate the necessity of forming additional loops between the looped ends of the uprights and permit the structure to lie flat when collapsed. The upright wires 13 upon both sides of the device are capable of swinging on the straight sections of the

wires

1 and 2, causing the framework consisting of the

wires

7, 10 and 11 to fall down and rest upon the base 1, one of the bails 18 folding inwardly and resting upon the top of the frame and the other bail folding inwardly above it, the whole apparatus assuming the position shown in Fig. 4 and forming a fiat package which can be conveniently inclosed in a paper wrapper or placed in a shallow carton.

In order to place the parts in position to be used, the wires 13 upon each side of the apparatus are raised in a vertical position, and the bails 18 are turned outwardly to permit the jars to be placed within the com- Patented Sept. 30, 1919.

and enables the jars thereby to hold the apparatus from collapsing. The bails 18 may then be utilized to" submerge the rack in a kettle of boiling water until; theicontents of the jars are suificiently heated. The rack lmay then belifted byithez bails 18- and thehermeticallysealed covers applied to the jars.

I claim,

1. A folding jar-rack, comprisinga base 1 section of woven wire, an upper' frameworkr havin com artments toireoeive the 'ars a r pair'or uprights on the opposite sldes-of the jar-rack. and spaced; inwardly-from the ends thereof having loops formed intheir ends,-- I and'eaeh having a pair-of eyes formed independently of the uprights. and rigidly attached: to .i said uprights between their looped ends,- with said eyes extending; inwardly and pivotally attached to said base section and the jar-rack and spaced inwardly from the ends thereof, each having a loop onits lower end to form a foot, and a loop on its upper end toleceive-as,10ml, a pair of eyes rigidly attached to each of said uprights with said eyes extending inward-1y with the lower 7 most of said eyes 'pivotally connected with said; base section; and with the uppermost t of said eyespivotally jcon'nected; with; said upper framework,and a pair of balls pivotally connected; withthe upper looped ends ofsaid upnigl1ts,- and. each of i said bails adapted: to foldinwardly. upon'said framework and legs at the ends of the jars-racial Dated thissixthzday of-"May, 1.918. 1 vHENRY AFHILDRETHL VVitnesses V RUFUS-z-B.
