WILLIAM J. KENNEDY, OF ST. LOUIS, MISSOURI.
Specification of Letters Patent.
Patented Feb. 22,1916.
Application filed April 19, 1915. Serial m. 22,309.
To all whom it may concern:
'Be it known that I, WILLIAM J. KENNEDY, a citizen of the United States of America, a resident of the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in File-Boxes, of which the following is a full, clear, and exact description, reference being had'to the accompanying drawing, forming a part of this specification.
My invention relatesto a sheet metal receptacle particularly :adapted for use as a file-box, one of the objects being to produce a strong and simple file-box made of thin sheet metal. By forming the box of thin sheet metal, I produce a very light and in,- expensive structure, and the required strength is obtained by folding certain parts of the thin sheet metal. The invention also includes certain specific details of construction, and certain combinations of elements which will be hereinafter described. I
Figure I is a perspective view of my filebox, showing the closure members in their open positions. Fig. II is a perspective view showing the 'closuresin their closed positions. Fig. III isan enlarged transverse section taken on line III-III, Fig. II, the middle portion of the box being broken away. Fig. IV is a section on line IV-IV, Fig. III, showing the manner of interlocking the rear wall with a side wall of the box. Fig. V is a fragmentary perspective view showing a portion of the top wall, the hinge member interlocked with said top wall, and a portion of a side wall. Fig. VI is a-sec tion taken on line VI-VI, Fig. V. Fig. VII is a section on line VII--VII, Fig. V. Fig. VIII is a section on line VIII, Fig. II.
The body of the box I have shown comprises a topwall 1, a rear wall 2, a bottom wall 3, and a pair of side walls 4. The top, rear and bottom walls, designated 1, 2 and 3, respectively, are preferably formed of a single sheet of metal, and the side walls are secured to said single sheet of metal. The margins of this single sheet of metal are folded outwardly and backwardly to provide flanges 6, 7 and 8. The top margins of the side walls 4 are folded over the top Wall 1 to provide U-shaped members 9 which re ceive the flanges 6 of said top wall, as shown most clearly in Fig. III. The lower margins of the side walls 4 are folded under the bottom of the box to provide U-shaped members 10 which receive the flanges 8 on the inforce the structure.
bottom wall 3; and therear margins of the side walls are folded in a similar manner to produce the U-shaped members 11 which interlock with the'flanges 7. ,It will be noted that the flanges 6, 7 and 8 are formed integral with the single sheet of metal, which constitutes the walls 1, 2 and 3, and that the U-shaped members 9, 10 and 11 are formed integral with the side walls 4. Byfolding and flanging the metal in the manner shown and described, I securely unite the box walls and at the same time very materially re- Therefore, the box body may be made of very thin sheet metal.
The side walls 4 are provided with vertical front edges 12, and inclined upper edges 13 which extend from the vertical edges 12' to the top wall of the box body. These edges, or margins, 12 and 13 are reinforced by folding the metal backwardly as shown most clearly in Fig. VII. The front margins of the side walls 4 are effect at 14 and the inclinedv upper margins of said walls are offset at 15. I
16 designates a front closure member hinged at its lower end to the bottom wall 3,
and provided with flanges 17 adapted to overlap the offset vertical margins of walls 4.
18 designates an upperclosure member hinged to the front edge of the top wall 1 and provided with a depending front flange 19 and triangular side flanges20. When the closures occupy their closed positions (Fig. II) the flange 19 overlaps the front closure 16 to retain the latter in its closed position, and the triangular side flanges 20 overlap and engage the inclined edges 13 at the side walls 4.
The front margin of the top, wall 1 is folded downwardly and backwardly, Fig. V, to produce a flange 21 which lies within the box body. A hinge member 22, extending across the box, is folded to provide a U-shaped member 22' which interlocks with flange 21. The upper closure 18 is pivotally connected to the hinge member 22. By fold across the box body vided withtop,
and inclined upper and provided with a which interlocks with U-shaped portion 27 VIII. The
the flange 25, as shown in Fig.
ahinge member 26 serves as means for reinforcing the lower portion of the box.
28 designates a hinge pin connecting the front closure 16 to the hinge member 26. Y My-file-box' ispreferably in the form of adrawer adapted to be associated with a number of similar filing-boxes, and it is preferably provided with a flexible pull strap 29, Fig. '11. This pull strap 29 is preferably a loop which surrounds the hinge pin 28. I
30 designates a card receiving member secured to the upper closure 18, see Fig. 11.
