BUCKETBOX CONSTRUCTION.

Application filed December 16, 1922.

To all whom it may concern:

' Be it known that I, AUGUSTINE Davis, Jr a citizen of the United States, and resident of Covington, in the county of Kenton and State of Kentucky, have invented a new and useful Bucket-Box Gonstructlon, of which the following is a specification.

The invention relates to truck tanks and more particularly to the bucket-boxes provided at the rear ends of the tanks for carrying the buckets, funnels and other necessary equipment. The object is to produce a light-weight and comparatively inexpensive bucketbox, possessing a high degree of strength and durability, suitable particularly for the smaller and lighter class of tank trucks.

In the accompanying drawings, fornnng a part hereof:

Fig. 1 is a perspective view of the bucketbox and part of the tank; n

Fig. 2 is a central longitudinal section through the bucket-box and end of the tank;

Fig. 3 is a disassembled perspective View of the bucket-box, the lining and the bottom;

Fig. 4 is a plan view of the blank for the back sheet;

Fig. 5 is a plan view of the blank of the upper front sheet;

Fig. 6 is a plan view of the blank for the strip that forms the bottom of the doorframe; and

Fig. 7 is a plan view of the blank for the sheet that forms the bottom of the bucketbox.

The numeral 1 designates the rear portion of the shell of a truck tank, and 2 an attached bucket-box embodying the invention.

The body or case of the bucket-box is made of sections of sheet-metal fabricated and welded together by the autogenous welding flame, or by electric welding, as hereinafter more particularly described.

3 is a back sheet section having an upwardly curved top edge and side wings 4, the latter when bent forward on the lines 5 forming the sides of the box. Upward extensions 6 from the side wings are curved toward each other and welded at their ends to each other and at the back to the curved edge of the back section, forming an arched top. On the ends of the wings 4 are lips 7 which are bent at right angles on the lines 8,

Serial No. 607,453.

9, 1O toform side door-frame structures 21 i of Z-section.

An upper front sheet or section 11 having a curved upper edge and preferably a straight, horizontal lower edge is welded to the front edge of the top, andits lower. portion is bent reversely on lines 9*, 10 to form the top 22 of the door-frame. The bottom 23 of the door-frame is formed by a narrow sheet 12 welded at the ends to the lower portions of the front edges of the sides and having its upper margin bent reversely at right angles on the lines 9 10 The corners of the door frame thus constituted are welded. The doors are marked 24.

The back section 3 is cut out in substantial conformity to the rear extension of the tank and welded thereto, the welding being preferably at lugs 3 The bucket-box as thus far described is completely open at the bottom and free of inward projections from the back or sides which would interfere with the introduction of a wooden lining 13. This lining is an important element of these bucket-boxes, preventing rattling of the contents and striking of sparks and affording a suitable compartmenting of the interior; and as the boxes have heretofore been made the lining has had to be constructed within the box,-

thus requiring somewhat lengthy and we pensive hand fitting. In the present invention the lining 13 is built separately, of a floor 14, back 15, sides 16 and partitions 177, so as to fit th "interior of the metal box, and is then inserted upward as a unit through the open bottom. It is then supported by inserting and welding in a. bottom sheet 18. This bottom sheet corresponds to area of the metal box and has flanges 19 at the four sides which are turned downward and welded at their lower edges-to the inner faces of the back, sides and lower front sheet, the weld 20 being slightly above the lower edges of these parts so that the clean straight bottom lines of the enclosure arepreserved.

While the preferred form of the invention has been illustrated, it will be understood that numerous changes in form and detail may be made without departing from essentials.

hat I claim as new is:

1. A bucket-box for vehicle tanks comprising a welded sheet metal structure ineluding a back, top, sides and afront containing a door opening, the back being united to the rear end of a tank, a-unit wooden lining structure including a back, bottom and sides inserted upward int-0 the welded structure, and a bottom sheet inserted into the bottom of the welded structure and Welded thereto.

7 2. A bucket-box for vehicle tanks comprising a welded sheet metal structure including a back, top, sides and a front containing a door opening, a unit wooden lining structure including a back, bottom and sides inserted upward into the welded structure, and a bottom sheet inserted into the bottom ofthe welded structure, said bottom sheet having downturued flanges which are welded to the inner faces of the vertical Walls of the Welded structure.

3. A bucket-box for vehicle tanks comprising welded structure formed of a back, sides bent forward from the back, side-doorframe structures bent from the edges of the "sides, a top formed of two continuations of the sides having their ends united, a top front sheet welded to the top and sides, and a lower front sheet welded to the sides, and connecting them at the bottom, a wooden lining structure inserted upward into said welded structure, and a bottom sheet inserted into the bottom of the welded structure and welded thereto.
