My invention relates to holdersfor drill. bits and more especially sets of drill bits in which holders the bits are placed and retained in a .predetermined arrangement according to 'size.
One of my objects is to provide an economical and compact construction of drill holder;
' Another object is to provide a construction of holder whereby the drill bits will be held in predetermined positions in the holder, against accidental displacement. therefrom, regardless of the turning of the holder upside down or. sidewise, yet be easily individually removable from, and replaceable in, the holder; particularly to the end of permitting a workman to storerthe holder, with. the bits therein, in hi'stooLboX, withoutrisk of the bits becoming displaced from theholder and intermingled with each other and with'such other tools as may be contained inthe box, and which would require sorting and gaging of a number of, the. bits each time to, find the right one to use,;-and other objectsas will be'manifest from the following description. 2 ;;Referringjto the accompanying drawings:

Figure 7 is a broken'view, in side elevation, of the structure of Fig. 6.
Figure 8 is an end view of another embodiment of the invention.
Figure 9 is a broken view in side elevation of the structure of Fig. 8; and
Figure 10 is an end view of another embodiment of the invention.
Referring to the construction shown in Figs. 1-3, the holder comprises a base portion II of any suitable resilient material, such as for example, soft rubber, molded into the desired'shape, as for example as shown, and having a recess [2 in its upper surface affording a marginal'upstanding rim 15.
The holder also comprises a plate 14, as for example ofmetal, set into the recess l2 and secured therein in any suitable manner, as for exwhich extend through openings 16 inthe plate H and into .openings H. in' the base portion wherein they are firmly secured by. the gripping actionofthe rubber.
The holder .in this particular instance is provided for holdinga set of drill bits l8 the shanks of which, in accordance with common practice, are of progressively greateridiameter, and thus there. is provided in .the plate [4, which constitutes a gage plate, a series of holes 19 extending therethrough and graduated in size in accordance with the diameters of the shanks of. the drill bits. Eachlhole [9 with which is associated the gage member and diameter of .the particularsize of drill-bit as showntobe received therein, is. of a diameter. 'slightly largerthan the diameter, of the shank of such particular drill bit but smaller than .the;;di'ameter of the next larger size of drill bit soas': to permit it tobe readilyinserted into the proper one of the holes l9.
The resilientibase portion ll of the holder has aseries .of holes-20 which register, respectively,
with'th holesgm; in the plate I 4,fthe holes 21] beingof less diameter than the holes 19 with which they, respectively, register and ofsuch diameter, smaller than the shanks of ;the drill bits inserted through the holes 19in the plate l4 and into. the holes 2| in the base [I that the shanks'will be firmly gripped by the resilient material and sufiiciently frictionally held in place in the holder as to prevent the falling of thedrill bitsirom the holder when thelatter isinverted or turned sideways, yet permit of their removal from the holder by the workman as desired.
One of the advantages of the provision of the base member of resilient material as described is that .being of such material, damage to other tools coming in contact with the holder is minimized.
In the construction shown in Figs. 4 and 5 the body of the holder is formed of a rigid channel bar 2 I, as for example of metal, presenting upper and lower flanges 22 and 23, respectively, and a rigid bar 24 of angle shape in cross section located in the channel of the bar 2| and secured at its flange 25 to the web 26 of the bar 2|, its flange 21 being disposed substantially parallel with the flange 23 and spaced therefrom.
The flanges 23 and 21 contain alining holes 28 and 29, respectively, of progressively greater diameters from one end to the otherof the holder, as in the case of the holder of Figs. 1-3, for receiving the shanks of the set of drill-bits l8 to be assembled with the holder.
- In this construction the drill-bits are fricample by the headed push-pins shown at I5 tionally, releasably held ineplace in the holder by means which are located at one side of the drill bits and yieldingly laterally press against the shanks of the drill bits; the means shown for this purpose comprising a strip 30 of resilient material, as for example soft rubber, secured fiatwise to the flange 25 of the bar 24 and of such thickness as to become engaged, and compressed, by theshanks of the drill bits in the assembling of the drill bits with the holder to the position as shown in the drawings. The face of the strip 30 at which it is engaged by the drill bits is preferably of arcuate form in cross section as shown at 3|, to facilitate the assembling of the drill bits in the holder. 4 V
The construction shown in Figs. 6 and 7 exemplifies the invention as incorporated in a holder in which the drill bits, instead of projecting from one side only of the holder, projects from opposite sides thereof in staggered relation to each other, a feature which permits the holder to be made of less length than in the case where all of the drill bits extend at one side only of the holder, while permitting adjacent drill bits to be spaced apart the desired distance for easy introduction of the drill bits into the holder and selective removal of the drill bits therefrom.
In this construction the body of the holder is formed of a rigid channel bar 32 having upper and lower flanges 33 and 34, respectively, and a rigid channel-bar 35 located in the channel of thebar 32 and secured at its web 35 to the web 31 of the bar 32 'with its flanges 38 and 38 substantially parallel with the flanges 33 and 34 and spaced therefrom.
- The flanges 33 and 34 contain holes at intervals along their length to receive the shanks of the drill-bits IB as in the case of the flange 23 of Figs. 4 and 5, the holes in the flanges 33 being staggered with respect to the holes in the flange 34, and the flanges 38 and '39 contain holes for the shanks of the drill bits Which al'ih'e, respectively, with the holes in the flanges 33 and 34 whereby the drill bits are positioned in the holder to "alternately extend rrom opposite sides thereof as exemplified by the showing in I. 7 The drill-bit receiving holes in the flanges 33, 34,38 and 39 may be rogressively graduated in diameter for the set of drill-bits continuously from one end to the other of the holder or any other arrangement of graduations provided as desired.
construction is provided with means Io'r fl'ictibnally holdihg the drill bits in price in the holder as in the case of the construction shown in Figs. 4 and 5, the resilient strip provided for this purpose and shown at 40, being located in the channel of the bar 35 and secured in place to the web of this bar.
The construction shown in Figs. 8 and 9 is the same as that shown in Figs. 4 and 5 except that the means for frictionally holding the drill-bits in place in the holder instead of being provided as a strip of resilient material such as rubber, is in the form of a series of finger springs 4|, as for example of spring metal, shown as formed integrally with a connecting strip 42 secured to holes in said base portion.
the base of the holder, the several fingers 4|, respectively, registering with, and yieldingly bearing against, the drill bits 18 introduced into the holder. Those of the parts shown in Figs. 8 and 9 which correspond with similar parts of the construction shown in Figs. 4 and 5 are given the same designating numerals.
The construction shown in Fig. 10 is the same as that shown in Figs. 1, 2 and 3 except that the body of resilient material in which the drill bits are frictionally gripped at their shanks and represented at 43 is partially encased in a rigid channel bar 44 the web portion 45 of which corresponds with the plate H of Figs. 1-3 and is apertured as in the case of this plate, to receive the shanks of the drill-bits.
While I have illustrated and described certain specific embodiments of my invention I do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered and the invention embodied mother -forms of structure without departing from the spirit of the invention. 7 g
What'I claim as newand desire to secure by Letters Patent is':
l. A holder comprising a base portion of resili'ent material having holes to receive the articles to be held in the holder and a "plate secured to said base portion and containing holes registering with, and slightly larger than, the
2. A holder comprising a base portion of'resilient material having holes to receive the articles to be held in the holder and having a recess in it's upper surface, and a plate located, and secured, in said recess and containing holes registering with, and slightly larger than, the holes in said basejportion.
