. FRUIT-TRAY.

Specification of Letters Patent.

Patented July 22, 1919.

Application filed September 30, 1918. Serial No. 256,200.

To all whom it may concern: l

Be it known that I, ALFRED M. LANE, a citizen of the United States,and a resident of the city souri, have invented a new and useful I111- provement in Fruit-Trays, of, which the following is a specification.

his invention relates to sheet metal trays.

for drying fruits and. particularly to trays with removable openwork bottoms adapted for facilitating the ventilation of the fruit. The principal objects of the invention are to produce a strong rigid, lightweight. tray of simple constructlon, which can be cheaply manufactured; to reduce the number of parts of the tray, and to provide 'for the easy assemblage of these parts; ,to facilitate the attachment and detachment of the removable openwork bottom; and also to pro vide a. means forstretching the removable openwork bottom over the tray frame and for securing the bottom in its stretched position to the tray frame.

The invention consists in the parts and arrangements of parts hereinafter. more fully described and claimed.

In the accompanying drawing, which .forms part of this specification and wherein like symbols refer to like parts wherever they occur,

Figure 1 is a plan view of a. fruit tray embodying my invention;

Fig. 2 is a side elevation of the tray;

Fig. 3 is an enlar ed cross-sectional view of the marginal portion of the tray;

Fig. 4 is a cross-section view showingthe parts of the tray in position to be assembled;

Fig. 5 is a side elevation of the strip'and of the tray be.- fore these members are bent into the desired shape; and I Fig. 6 is a side elevation of the clamping before being bent into the desired shape. p

The tray shown in the drawings comprises a continuous open main frame 7, a clamping frame 8 and woven wire bottom 9. The main frame 7 is preferably made from a continuous strip ofsheet metalrolled intoua strip 10 (see Fig. 5) substantially channel shaped in cross section and bent to the ,desired contour as hereinafter mentioned. At the side margins of the strip are sheet "metal "flanges-11 and 12.which project outmedia -er rightangles from the same face of St. Louis. and State of Mis- :tinuous strip of the strip,'thus forming an outwardly facmg longitudinal groove or channel 13. The longitudinal side flange 11 projects a greater distance from ,thebody portion of the strip than the opposite flange 12, and is rebent inwardly substantially parallel with the body of the strip, as at 14, and terminates 1n a flange15which is inclined obliquely outwardly away from the body portion of the strip. While the sheet metal strip is still straight, a flat bar. 16.is placed in the groove or channel formed in the strip 10 and is spot-welded at intervals to said strip as indicated at 17in Fig. 5 of the drawing. The outer surfaoeof the bar terminates flush with the longitudinal side flange 12 of the strip thus leaving a space between the rebent portion 14 of the side flange 11 and the outer face of the bar 16. The bar 16 is of "the same length as the strip 10 and is positioned therein so. as to" project a suitable distance beyond one end of the strip and to terminate short of the strip the same distance at its opposite end' leaving a space or pocket 18. The main frame 7 is. formed by bending the strip and bar intothe desired shape, which is preferably rectangular, the opposite ends of the strip and bar being brought together at one side so as to abut. This bringing of the opposite ends of the strip together causes the projecting end of the bar 16 to enter. the space or pocket 18 in the oppositeend ofthe strip, The abutting ends of the strip are preferably buttwelded; and likewise the abutting ends of the bar are butt-welded, the lines of the two welds being offset from each other.

The clamping frame 8 is made from a conof sheet metal rolled or shaped into a strip 19 (see Fig. 6) of substantially angular section. The longer leg of the angle-shaped strip l lls provided with a V- shaped rib 20 adjacent. to its outer margin.

he clamping'frame 8 is formed by bending the strip 19 into a shape corresponding to that of themain frame 7, the opposite ends of saidstrip being brought together and butt-welded In assembling the parts of the tray,.the main frame 7 is placed bottom side up (that is with the rebent flange 14L lowermost) as shown in Fig. 4 of the drawing. A woven wire fabric, which is. larger than the main frame and of a shape corresponding to that of the main frame, is then laid over the frame, and then the clamping frame 8 is positioned over the woven wire fabric with its longer, ribbed'leg extending downwardly. The clamping frame is then forced downwardly, the lower end of the ribbed legv engaging the woven wire fabric, stretching the wire fabric over the frame 8 and forcing its margin downwardly alongside of the 'fiat bar 16 of the main frame .T-untilIthe lower angle of the V-shaped rib 20 on the longer leg ofthe clamping fr me 8 seats against the outwardly inclined flange 15 of the mainframe 7. This forcing of-the clamping frame over the main frame firmly clamps the margin of the wire fabric betweenthe outer face of the main frame and the inner face of the clamping frame. While the clamping frame is frictionally held,in place on the main frame by being forced. over the same it maybe additionally held in placeby screws 21 which extend through the clamping frame and wire bottom, and-are threaded into the main frame 8, one screw being placed on each side of the frame. 1% the welded joints it is preferable --to locate a screw on each side of the joint-for strengthening purposes. a

Some of the principal advantages of a fruit tray constructed in accordance with h fQF g g d scr ption ,are its. great simplicity; its cheapness of manufacture; its great economy of materials; and thefacilit-y it affords for repair and replacement.

What I claim is:

1. A fruit tray comprising an open main frame having, an outwardly extending. top portion, said portion having agroove in its underside, an openwork bottom extending across the bottom of said frame and having its marginal portions turnedup along the outside faceof the frame,,and,a frame arranged outside of said main frame with its upper margin extending into said groove and clamping the marginal portions of the openwork bottom to said main frame.

2. vA fruit tray comprising-an .open.,main frame having; an outwardly projecting top portion, said portion havinga groove in its under side, an openwork bottom extending across the bottom of said, frame and having .its marginal portions turned-up, alongthe outside face of theframe, and a frame of angular section having a continuous rib formed therein, said frame. be ng arranged outside of said. main frame (with its, upper margin extending into said groove and clamping the marginal portionsof the openwork bottom to said main frame, and means for securing said, clamping frame to said main frame. V i 8 A. fruit tray comprising. anppen main frame having an. outwardly extending. top portion, said lportion having in itsunder side a groove whose. outside wall inclines. oute y d d v v a an remv rkf et of said bottom tom extending across the bottom of said frame and having its marginal portion turned up along the outside face of the frame, and a framefor clamping themargin to the frame, said clampin frame being adapted to embrace the outside and bottom of said main frame and having its upper margin extending intosaid groove.
