L.. HAMMOND DYNAMITE BOX Filed Sept. 13. 1923 LAURENCE HAMMOND, 0F SPNGLEB, PENNSYLVANIA..

DYNAMITE BOX.

Application led September 13, 1923. Serial No. 662,490.

To all 'whom t may comem: l

Be it known that I, LAURENCE l-LaMMoND, a citizen of the United States, residing at Spangler, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Dynamite Boxes, of which the following 1s a specification. v

This invention relates to an improved box for carrying dynamite and which, when constructed in reduced size, may also be employed for carrying caps and fuses.

The invention seeks tov provide a strong tight wooden box wherein nails or other metal parts will be absent.

The invention seeks, as a further object, to provide a box embodying interli'tting joints throughout, so that moisture will be excluded. I

And the invention seeks, as astill further object, to provide a box embodying a handle at one end thereof so that the box may be readily carried and wherein .the door will be so arranged with respect to the handle and the legs of the box that the door will be normally disposed to gravitate to closed position for maintaining the box closed.

Other and incidental objects will appear hereinafter.

In the drawing:

Figure 1 is a perspective view of my dynamite box;

Fig. 2 is a vertical sectional View takenv medially through the device;

Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 2, looking in the direction ofthe arrows, and

Fig. 4 is a detail sectional view on the line 4 4; of Fig. 2, looking in the direction of the arrows.

In carrying the invention into effect, I

lembody a box body including side walls 10,

top and bottom walls 11 and 12a-nd a back wall 13. The top and bottom walls are connected to the side walls by dovetail joints 14 while tongue and groove joints 15 are provided between the back'wall and the side walls as Well as between the back wall and the top and bottom walls. In this connection, it is to be noted that the grooves in the rear margins of the side walls open through the upper end edges of said walls so that the back wall may be assembled between said side walls by shifting the back wall'downwardly therebetween, while the top wall 11 1s, as particularly brought out in Fig. 2,

p walls are extended below the bottom wall to form legs 17 for the box body and are continued above the top wall to define spaced upstanding wings 18 preferably having curved upper edges. Extending between said wings medially of the box body in spaced parallel relation to the top wall 11 is a handle 19 provided at its ends with re- 'duced portions 2O projecting through said wings. Since thev side walls 10 are held against separation by the top and bottom walls, displacement of the handle will be prevented and, as will be seen, I provide a box body which is not only closed at the joints between the walls thereof but which will be ltight and exceedingly rigid. Formed in the side walls 10 at their forward margins are vertical grooves 20 and slidable between said walls is a door 21 provided at its longitudinal edges withv tongues 22 fitting in said grooves. At the upper endsI of the grooves 20, the side walls 4are cut away, as indicated at 23, to facilitate the introduction of the tongues of the door into said grooves while attheir lower ends, said grooves are closed beneath the bottom wall 12 by filler strips 23. Formed in thedoor near its upper end is a finger notch 24 defining a shoulder at the upper end of the notch for engagement to lift the door.

As previously intimated, the present box is formed entirely 0f wood and, as will now be seen, the door 21 will normally gravitate downwardly to rest at its lower edge against the bottom wall 12 for maintaining the box closed while the legs 17 will serve to space the bottom wall from the ground and thus reduce the liability of moisture reaching the bottom wall. The handle 19 provides, of course, a convenient means of carrying the box and attention is directed to the fact that a finger of the hand grasping the handle may be engaged in the notch 24 of the door for lifting the door when the other hand of the operator may be inserted beneath the door and employed to push the door upwardly and remove the contents ofV having side walls continued to form legs extending beneath the box vbody as Well` as wings upstanding. from the box body, a hanclle extending between said wings, and a' vertically movable door gravitating to normally close the box body. Y.

2. In a dynamite box, the combination of a vbox body having legs extending therebeneath, a horizontallyl disposed handle mounted above the box body, and a vertically movable door gravitating to normally close the box body, the upper end of the door being engageable by a finger of the hand grasping the handle for lifting the door.

3. 'In a dynamite box, the combinatior of .an oblong box body having side walls continued at one end of the box body to form legs and also continued at the opposite end of the box bod to form pstanding wings, a handle exten ing between said wings, and a door slidably mounted upon the side walls to normally, gravitate downwardly to closed position. e

4. A dynamite box including a box body comprising side, back, top and bottom walls having intertting jointed connection, the i side walls being continued below the bottom wall toform legs and also being continued above the top wall to form upstanding wings, a handle extending between said wings, and a door slidable upon the 'sidewalls and normally gravitating to close the box body.

In testimony whereof I aix my signature. LAURENCE HAMMOND. [n s.]
