FIcE DRILL CASE Moses Daniel Nissenbaum, Brooklyn, N. Y., assignor, by mesne assignments, to General Hardware Mfg. (30., Inc., New York, N. Y., a corporation of New York Application May28, 1945, Serial No. 596,342

1 Claim. 1

The present invention relates to drill cases and more particularly to the'portable type.

lhe principal object of this invention is to provide a drill case of novel and improved construction, which is compact when closed, and

upon merely opening the case, a drill tray housed therein and carrying a plurality of drills, is automatically shifted to such position that'the drills In the accompanying drawing forming part I of this application, similar characters of reference indicate corresponding parts in all the views.

Fig. 1 is a perspective View of a drill case embodying the teachings of the present invention.

The device is here shown in open or use condition.

vice is shown in closed condition.

Fig. 4 is a perspective view of the drill tray member.

Fig. 5 is a perspective View of the cover member of the case.

Fig. 2 is a section taken at line 24 in Fig. 1.' Fig. 3 is similar to Fig. 2, except that the deits" I3 are associated in hinged relation with each other at one of their respective ends. Upon such assembly, the ends of the pin l8 are formed with heads in exterior abutment with the sides I2 of the box member [2.

In the embodiment illustrated, the box cover member i3 is formed with a front flange I3" and the slots or spaces l9, whereby upon closing the case formed by the box members I! and t3, the front wall l2" of the box member l2, will set within the slots |9, and flange l3" will engage the exterior surface of the wall I2, to maintain the case closed, with the box cover member I3 nested within the box member l2, and the drill tray ll nested within the box cover member I3.

The drill tray ll may be formed of a sheet metal body 26 having integral lugs I4 at its sides near its bottom edge; said lugs being each rearwardly bent perpendicular to its rear face. Extending from said rear face of the body 26, along its top edge, is a channel 20, having the series of aligned holes 2! and 22 for positioning a plurality of drills 23 the'rethroughf'the bottoms of said drills resting on a channel member 24 which is also carried on the rear face of said body member 26. Members 28 and 24 may be mounted or Fig. 6 is a similar View of the box, member of the case.

Fig. 7 shows the pin used for assembling all of said members into a unitary structure.

In the drawing, the drill case I Bcomprises a drill tray member designated generally by the numeral H, a box member 12 which has no rear wall, and a cover member designated generally by the numeral I 3, which serves as the box cover.

The box members [2 and 13 are in telescopic relation, the cover member l3 fitting between the.

sides i2 of the box member i2, while the lugs M of the drill tray member H, fit between the sides 13' of the box ,cover member 93. Holes 15 in the sides of the box member l2, holes its in the sides of the box cover member l3, and the holes ii in the lugs 14 of the drill tray member H, are provided in order to receive a pin l8 therethrough, whereby said members ll, 12 and secured to the body 25 in any suitable manner. The length of succeeding sizes of drills being progressively larger, and it being desirous that the upper points'of the drills 23 shall lie in a. line substantially parallel and near to wall l2, the drill rest element is preferably slanted with respect to the member 20. On the front surface of body element 26, the drill sizes or other indicia 21, may be marked to indicate drill positions and data relating thereto.

The box cover member l3 carries a drill tray carrying element 25, which is preferably in the embodiment illustrated, of arcual cross section, and extends from-said member terminating in an edge 25. The lug M is free to move within said arcual member 25, about axis pin l8. When the drill case I0 is closed as in Fig. 3, edge 25' is spaced from drill tray body 26.

In operation, to open the drill case I 0 from its closed position of Fig.3 to its open condition as in Fig. 2, the box cover member i3 is manually swung counterclockwise. When said cover member had travelled angularly the obtuse angle shown to exist between said cover member and the drill tray II in Fig. 2, edge 25 of the tray carrying element 25 will contact the rear surface of tray body member 26, and upon further continued movement of said cover member i 3, the

small sized drills and may be considered as shown full size.

To close, cover member I3 is manually swung in a clockwise direction. The angle between said cover member and the tray member will be main tained until the tray ll comes to rest on the floor of the box member I2, whereupon further movement of the cover member 13 to the position shown in Fig. 3, edge 25' will move away from the drill tray member 26.

This invention is capable of numerous forms and various applications without departing from the essential features herein disclosed. It is therefore intended and desired that the embodiment herein be deemed illustrative and not restrictive and that the patent shall cover all patentable novelty herein set forth; reference being had to the following claim rather than to the specific description herein to indicate the scope of this invention.

I claim:

In a drill case, a box member having a wall opening, a box cover member hinged to the box member on an axis near said opening, a drill tray positioned between the box and cover members, pivotally mounted at its lower end about said axis and a drill tray shifting member extending from the-box cover member in said wall opening and terminating at a position spaced from the drill tray; said drill tray shifting member being interiorly substantially concave and housing the lower end of the drill tray and having a path of movement between the drill tray and the box member, adapted upon opening of the case by movement of the box cover member, to engage the drill tray only after the box cover member has been moved an angular distance of an obtuse angle and upon further movement of the box cover member; to swing the tray member an angular distance of an acute angle.
