This invention appertains to tool'holders or racks and more particularly to a novel ldevice for holding a set of dilerent sized twist or like One of the primary objects of my invention is to provide an improved rack or holder for a set of different sized drill bits with novel means forming a part of lthe rack or holder for permitting the convenient Vselection Vand. grasping of any desired drill bit.

Another important object of my invention is the .provision of a drill holder or,AV rack embodying a plurality' `of pivoted sockets for receiving,

. the different sizes of drills with means consisting of spring rpressed. keys for engaging and operating any one of thesockets. to move the same to an elevated position outof alignment-with the otherv sockets wherebyr the drill can `be conveniently taken from its'socket.

A further important object of my invention is the provision of resilient means carried by the rack or holder for engaging the sockets and for holding the sockets against accidental movement either in their raised vertical position or in their lowered horizontal position.

A still further object of my invention is to pro-v vide an improved holder or rack for drills of the above character which will be durable and eiiicient in use, one which will be simple and easy to manufacture, and one which can be-placed upon the market at a reasonable cost and readily carried in a tool chest or case. l

With these and other objects in view, the in vention consists in the novel construction, ar-

rangement and formation vof parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which drawing: 1

Figure 1 is a fragmentary top plan view of my improved drill holder or rack showing parts thereof Vbroken away and in section.

Figure 2 is a transverse section through my improved drill holder or rack showing one of the Vdrill sockets in its elevated position for permitting the removal of the drill therefrom. Y

Figure 3 is a similar view showing the drill socket in'its normal position, and

Figure 4 is an enlarged detail sectional view showing the top wall of the case or rack with the guide opening therein for oneoperating key of a drill socket. Y l

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates my improved drill bit holder or rack which comprises a longitudinallyextending flat bottom wall IU, kwhichcan f be'formed of sheet metal ofthe desired'gage,l if` preferred.- Arranged -in spaced relation to the bottom Ywallll is a top ,wall ri I, whichcanlike- 5 wise be formed of sheet metal of the desiredgage, Y if preferred. The bottom and top walls IIO `and Il are connected together by sidewalls orblocks I2 and it is to be noted that the top wall:v Il terminates slightly short ofthe front edge of 10 thev bottom wall. I, for a-purpose, vwhich will be later described. l v Extending longitudinally of the holder or rack 'isfa' pivot shaft I3, which shaft is located substantially-e-qui-distantly from the bottom and top 15 walls it) and II and forwardly of the front edgeV of the'topwallf'l I. This lpivot shaft I3. has its ends anchored in the side walls-'for blocks ,Iad-V jacent' to" the front ends thereof.' Rockably p mounted on the pivot shaft I3 is a-plurality `of 20 sockets I4 for. receiving the different sizesof drill bitsV I5. These sockets are provided-with fiat inner walls I6, for a purpose, which will be later described. It is to be also noted that each socketY I4 carries a leaf spring Il, the free resilient end 25 of which extends through a slot I3 in the socket for frictional contact with the-drill bit carried thereby. so as to respectively hold the drill bits against accidental displacement from the sockets.

It is to be also noted` that the pivot shaft I3 is 30 llocatedv intermediate the ends of thesockets I4, but preferably closest the rear end of the sockets than the front ends thereof. Normally` the sockets I4 are swung in a horizontal plane in longitudinal alignment with one another and the forward ends 35 thereof rest upon a longitudinally extending horizontally disposed rest rod I3 which rod can be supported by end brackets 2U secured in any prel ferred way to the lower wall IU, as shown, ortov the end blocks I2.

In order to provide means for facilitating the selection and grasping of the ldesired size drill bit, I provide a plurality of selector keys 2 I. These selector keys 2| extend through suitable openings 22 formed in the top wall II and each selector 45 as shown in Figui-e im facilitate the application thereof to the `top wall H vand the upper faces of the keys canl carry suitable indicating indicia removed-from the sockets, in view of the fact that the same is held in an elevated plane aboveU the other drill bits.- After thedri-ll; bitfjhasj'fbeeni used, the same is replaced in the socket and then swung manually to its'lowered normal'posit-ioniH In order to prevent the iaeoidental sw-ingingjY movement of the sockets when'the same are in their lowered horizontal'position or whenv'the- Y be engaged by the springs and thus the springs 25 willhold the same in their elevated positions. From the foregoing description, it can be seen that I have provided a .novel` drill bit holder or rack in which not only will the bits vbe kept'in proper 'placei andY held' against movement but means by which any desired'sized drill can be readily seleetedand removed yfrom said rack.-

Changes in details may be made without de'- parting from the spirit or the scope of this invention, but:-

What I claim as new is:

1. A holder for drill bits of different'sizes com- `prising a casing including a top and bottom wall, a plurality of independently pivoted sockets for receiving the drill bits, spring means engaging each socket for normally holding the sockets against swinging movement, resilient key bars mountedyin' the casing normally arranged about the rearv ends'of .the drillr socketsin-rear of the pivotv points thereof, andkeys for operating the resilient key bars slidable through the top wall of'the casing.
