The present invention relates to drill cabinets and moreparticularly to theportable type.

The principal object of this invention 'is "to provide "a drill "cabinet of "novel :and improved construction, which is compact 'when closed, 'and upon merely opening "the cabinet, 'rows of drills housed therein, are automatically "shifted into such positionthateachidrill becomes readily displayed and easily and individually accessible, and upon ,closingof "said "cabinet-said rows of drillsjautomatically shift into superimposed relation to efiect, such a'desired compact article.

AFfurther-"object"hereof 'is to provide a drill cabinet 'of'the character set "-forth of novel and improved construction which is reasonably cheap to manufacture, convenient to use, certainin its automatic "actions aforementioned and *fiicient incarrying out the purposes for which-it is designed.

Other objects andv advantages will become manifest as this disclosure proceeds. In the accompanying drawings, comprising part "of this application, similar charactersof reference indicate corresponding-parts mall the views.

In the drawingsthenumerals'l-5 and I6 con sti'ti-ite a pair'of-telesccpic'bcxmembers inhinged relation atone of' theirrespective ends, at H. Member F5, *which is the inner one, is provided with slots-l3 at its remote'free side-ends so that front flange 15 so formed'may clamp with the front wall Hi, to maintain the box or cabinet in closed-con'ditionand yet easy to be opened. Provision is made so that member I5 can move but a little more than a right angle; edge l5" serving as a stop.

-However, in-such setup, meaning minus --the members oi Figs. .6- and '7.,.each. of said drill trays L9, 2.0. and -2.l.,'is free to be moved individually towards the doorzl 5. As a further-improvement therefora-Iprovide near-the top of each-said drill trays, A except the one first --to' enter the "box section It; and asapplied to therembodiment'shown, near-the top of each-of the drill' trays 2'0, and 2| is a hingedly"mounted'shelf'memberindicated by the numeral 29. in one instanceand'by the numeral'30 in'the othenthe'respective axis of such hinged "or pivoted connections being indicated'by' the numeral29' and'tfl'. Forward of shelf 3ll,'preferably "at eachendthereof, extends arr-arm "30'which connects as a hook to engage the drill tray 20. Likewise forward of shelf"29, preferablyat'ea'ch endthereof, extends an arm 29' which actsasa cam in a manner hereafter-explained. 'It is evident'that, as in Fig.

.1,'the'drill trays "I9, 20, and 2| are associated in'a morestable set upwhen said shelves 29 and 30 and their' associatedarms are included in the device. Said shelves may be utilized to carry drill's'izeindications corresponding to adjacent drill"socketsas shownin'theFigs. 2, 6 and 7.

In operation, to'open the cabinet it is rested on boxsection l6 whilecover I5 is swung upwardly from its position in Fig. 3, until it reaches its final rest position as in Fig. 1.

components because such is accomplished automatically as follows:

Referring to the Fig. 4, which shows a partially opened position of the cabinet, the drill trays l9, 20, and 2| and the shelves 29 and 30 will all droop downward due to gravity and the drills of series 26 will glide along the floor of the cabinet member l6 as will cam 29', while hooks 30' will glide along the shelf 29 until the amount of swing of the cabinet cover I is sufficient so that said hooks engage the drill tray while shelf 29 will set itself between the drill trays I9 and 20 and then, successively, the movement of the respective drill trays I9, 20, and 2| will be stopped by the door member l5 because of the beveled or other shaped bottoms of said drill trays. The device, now opened as in Fig. 1, displays all of the drills and each of them are readily accessible for withdrawal from their respective sockets and likewise easily replaceable therein.

In closing the cabinet, only the door I5 is swung to its position, as in Fig. 4, and then final- 1y as shown in Fig. 1, during which travel said door l5 at first carries along with it all the .drill trays I9, 20, and 2|, set up, spaced and associated as in Fig. 1, until tab 29' comes into contact with the floor cabinet section l6 whereupon shelf 29 is automatically swung upwardly thereby shifting hook 30' also upwardly, thus releasing the drill tray 2|. All the parts are now free to automatically assume the position as illustrated in Fig. 3, which they do as the cabinet finally is fully closed.

As modifications, the drill tray 20, for instance, may be relieved of that portion thereof under line A, and the interior cabinet components shall consist of either 20, 30 and 2|, or else, I9, 29 and 20. In fact only one of the drill trays need have such lower portion to act as a stop against l5, and depending which one that is, so will we need choose properly the members 29 and 30, for in some instances spacers 29 will sufiice, and in others, the hooking feature of member 30 becomes necessary.

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 patent shall cover whatever features of patentable novelty are herein disclosed: reference being had to the following claims rather than to the specific embodiments shown and described herein to indicate the scope of this invention.

I claim:

In a drill cabinet of the character set forth, a box member. a cover member hinged thereto. a number of drill trays positioned between the box and cover members, pivotally mounted near their lower ends to the cover member along spaced non-colinear axes respectively; all such axes being parallel to the line of the cover hin e connection and forward of each other; each drill tray having a point at-its bottom at a greater distance from the axis of its pivotal connection. than the shortest distance from said axis to the cover member, whereby upon opening the cabinet by an upward swing of the cover member, the drill trays will automatically assume spaced and relatively radial positions, and upon closing of the cabinet by a downward swing of the cover member, said drill trays will be automatically swung towards each other and become housed within the cabinet.

2. In a drill cabinet of the character set forth, a box member, a cover member hinged thereto, a drill tray positioned between said members, pivotally mounted near its lower end to the cover member along an axis parallel to the line of the cover hinge connection; said tray having a point at its bottom at a greater distance from the axis of its pivotal connection, than the shortest distance from said axis to the cover member, a second drill tray positioned between the first drill tray and the cover member, pivotally mounted at its lower end to the cover member along an axis parallel to the line of the cover hinge connection and forward of the axis of the pivotal connection of the first drill tray, and a spacer member positioned between said trays, hinged at one end to the second drill tray along an axis parallel to the line of the cover hinge connection, and having a forward element adapted to extend beyond the first drill tray; whereby upon opening the cabinet by an upward swing of the cover member, the spacer member will automatically fall between the drill trays and serve as a spacer between them, and the drill trays will automatically assume spaced and relatively radial positions, and upon closing of the cabinet by a downward swing of the cover member, said forward element of the spacer member, upon contacting any component of the drill cabinet, will be automatically shifted upwards, whereupon the drill trays will be automatically swung towards each other and become housed within the cabinet.

3. In a drill cabinet of the character set forth, a box member, a cover member hinged thereto, a drill tray positioned between said members, pivotally mounted near its lower end to the cover member along an axis parallel to the line of the cover hinge connection; said tray having a point at its bottom at a greater distance from the axis of its pivotal connection, than the shortest distance from said axis to the cover member, a second drill tray positioned between the first drill tray and the box member, pivotally mounted at its lower end to the cover member along an axis parallel to the line of the cover hinge connection and forward of the axis of the pivotal connection of the first drill tray, and a spacer member positioned between said trays, hinged at one end to the first drill tray along an axis parallel to the line of the cover hinge connection, and having a forward hook element adapted to extend beyond the second drill tray and engage same in hook fashion, whereby upon opening of the cabinet by an upward swing of the cover member the spacer member will automatically fall between the drill trays and serve as a spacer between them and the drill trays will automatically assume spaced and relatively radial positions and become secured to one another by said hook element, and upon closing of the cabinet by a downward swing of the cover member, said hook element upon contacting any component of the drill cabinet, will be automatically shifted upwards, whereupon the drill trays will be automatically swung towards each other and become housed Within the cabinet.
