BOX.

SPECIFICATION forming part of Letters Patent No. 695,618, dated March 18, 1902.

Application filed August 26, 1901. Serial No. 73,275. (No model.)

To all whom it may concern.-

Be it known that I,Auousrus F. MACK, a citizen of the United States, residing in the city of New York,borougl1 ofBrooklyn,county of Kings, and State of New York, have invented certain new and useful Improvements in Boxes, of which the following is a specification sufficient to enable others skilled in the art to which the invention appertains to make and use the same.

My improvements relate to boxes in which metallic frames are used to support and reinforce the bottom, side, and end boards, and are designed to be applied more particularly to boxes for the transportation of milk and other bottles where the boxes are subjected to rough handling and'soon wear out under ordinary conditions of use.

The distinguishing feature of my invention consists in a basic skeleton or frame made from a single continuous piece of metallic angle-bar bent to form parallel upper cross members, corner-posts, and floor members, the ends of this metallic angle-bar being rigidly united to constitute a one-piece frame, into I which the bottom, side, and end boards fit,

In the accompanying drawings, Figure l is an isometrical view of my rectangular skeleton box-frame in its simplest form; Fig. 2,

an isometrical view of the same upon a larger I scale, showing the addition of braces. Figs.

3 and 4 are respectively isometrical views of f f the side pieces of the box, showing the inner and outer surfaces thereof; Figs. 5 and 6, similar views of the end pieces of the box. Fig. 7 is a view, on a smaller scale, of a plain box-bottom made in two pieces, Fig. 8 is an isometrical view of the box with all the parts assembled. Fig. 9 is a transverse vertical section of the box, upon an enlarged scale, upon a plane passing through the handlebrace; Fig. 10, a horizontal sect-ion of the same; Fig. 11, ahorizontal sectional detail of a corner of the box upon plane of line 11 11, Fig. 9; Fig.12, avertical sectionaldetail upon plane of line 12 12, Fig. 10.

My invention involves as a fundamental structure the rectangular frame F, made of angle-iron or other metallic bars or rods substantially rectangular in cross-section, the concave surfaces facing inward, so as to constitute horizontal and vertical flanges for the reception, support,and protection of the edges of the'bottom, sides, andv ends of the box. The frame F is made of a single bar or rod of angle-iron or other metal cut and bent into the rectangular form shown, the ends of the bar being welded together, so as to create a continuous integral structure consisting of the floor members ff, the corner-posts f f, and the end cross-bars f f as shown in Fig.

l, in which form the frame may be used for the reception and support of the bottom section B or sections B B, the'edges of which it will fully protect, While strengthening and reinforcing the box as a whole. I prefer, however, in order to prevent the possibility of the spreading apart of the parallel members of the frame, as might possibly happen under undue strain, to use braces a and a, the opposite ends of which are rigidly secured, preferably by rivets, to opposed members of the frame. Thus in the drawings the end braces a a are shown as secured to and extending between the lower portions of the opposed flanges of the corner-posts) f, while the side braces a a are secured to and extend between the opposed flanges of the cornerposts at opposite ends of the frame, with the result that the end braces a a preserve the alinement of parallelism of the floor members f f, while in like manner the side braces insurethe alinement of the upper cross-bars 2 In this connection it is obvious that a like result may be attained, for instance, by securing the braces a a directly to the parallel floor members f f and the braces a a to the end bars f f so that I do not confine myself strictly to the identical structure shown, since various modifications andmechanical expedients may be resorted to without departing from the spirit and intent of my invention. I

The bottom 13 is preferably made in two or more sections B B to facilitate placing in po-' their upper edges at the corners s 3 being pressed under the horizontal flanges j j of the upper cross-bars f The end pieces are next placed in position with their lower edges 6 e resting against the bottom ,their vertical edges against the inner surfaces of the side pieces, and their upper edges under the flanges j of the end cross-bars f f It will thus be seen that the parts lock each other successively in position, it being only necessary to secure the end pieces E E against movement in order to insure the stability of the structure as a whole. This I accomplish, preferably, by means of corner-brackets (J 0, resting against the inner surfaces of the end pieces E E and side pieces S S at their point of intersection, as will be understood by reference to the last four figures of the drawings. These corner-brackets are preferably made of angle-iron, but may be made of wood or any other material in any desired form in cross-section, the essential feature being the use of strips or binders which may be secured rigidly to the frame F for the purpose of positively locking the sides S S and ends E E against movement. A simple and effective way of effecting this result is to rivet the corner-brackets C to the corner-posts f f, as shown in Fig. 10, in which 0 represents the rivets. Any other mechanical expedient may be resorted to in securing the corner-brackets rigidly to the frame F.

The bottom, side, and end pieces are made of wood or any other desired material. When made of wood of sufficient thickness, I rabbet the upper edges of the side pieces, as at s, and the lower edges of the end pieces, as at 6 to receive and overlap the braces a and a, respectively.

The frame, &c., may be used either with or without the handle-brace h, shown as riveted centrally to the side braces and as formed with extensions h h, which project downward in front of the side pieces S S.

By my improved construction the bottom particularly of the box, as well as its ends and sides, is secured firmly and rigidly in position against displacement, whereas in the case of boxes at present in use for the purposes indicated the bottom is the Weakest part of the box and frequently collapses, spilling the contents of the box. It will be seen also that the edges of the floor, sides, and ends are completely isolated and protected by the flanges constituting the angle-bars of metal,the frame F bearing the brunt of all strain and contact. Furthermore, in this connection it will be noted that the upper surfaces of the crossbars f f (and of the handle-brace h when used) constitute raised bearings upon which the bottom of another box may be safely placed without subjecting the sides, ends, or bottom sections of the box to additional weight or strain.

When for any reason it is desired to substitute or replace the whole or a portion of the bottom or a side or end piece, this may be easily accomplished by removing the corner-brackets temporarily, so that part may be removed from time to time and the life of the box as a whole prolonged indefinitely.

What I claim as my invention, and desire to secure by Letters Patent, is-
