Application March 17,

3 Claims.

This invention relates to stands or fixtures, more particularly adapted to hold various types of drill bits, wherein such drill bits are conveniently placed and retained in the order of their respective sizes.

A drill stand or holder of this general type may comprise a series of parallel plates of equal thickness, separated from each other by spacer bushings or other means, and held in such fixed relation to each other by rivets, screws or bolts. Two of the above mentioned plates may be provided with like series of holes, slightly larger than the diameters of the drills which they accommodate, said holes increasing or decreasing in diameter each from the other by an increment similar to that by which the drills differ in their consecutive sizes. The holes may also be arranged in their respective plates so that any two holes of like size are in vertical alignment with each other, whereby the drill of corresponding size is readily inserted therethrough, coming to rest on a third plate, not perforated, which forms the base of the stand or holder. The holder is desirably provided with fractional, numeral or letter size designations by which means the desired drill may be readily selected or replaced in the holder.

As a variation, the middle plate may be omitted, the bottom plate being of increased thickness over the top plate, and containing a series of holes extending only part way therethrough, and co-operating as already mentioned with a similar series of holes in the upper plate.

Drill stands constructed as just mentioned include a number of parts and may be relatively expensive to manufacture, but nevertheless have certain advantages over common forms of drill stands or holders, which have usually included simply a strip or block of suitable material provided with a series of holes extending part way therethrongh and adapted to receive the drills corresponding to the respective hole sizes. Such that they contain unnecessary parts, or too few parts to aiford adequate support, or are too heavy or unwieldy for convenient handling, besides being relatively expensive in construction due to the time required for production of the drill stand.

One object of my invention is to provide a drill stand or holder which is simple in structure and in which separate assembling means are unnecessary.

Another object is to provide. a drill holder which is light in weight and convenient to handle.

A further object is to enable the drill holder to be pleasing in appearance and inexpensive to manufacture, and which may thus be easily acquired by those to whom such a device is a necessity.

C. Failor, Upper Mont- 1932, Serial No. 599,605

Other objects and advantages of the invention will be hereinafter specifically pointed out, or will:1 become apparent, as the specification procee 5.

With the above indicated objects in view, the invention resides in a certain novel construction and combination and arrangement of parts, clearly described in the following specification and fully illustrated in the accompanying drawing, which latter shows an embodiment of the invention as at present preferred.

In the drawing,

Figure 1 is a top plan view of adrill stand embodying the present invention;

Figure 2 is a front elevation of the drill stand illustrated in Figure 1, showing a drill bit in place;

Figure 3 is a longitudinal sectional view, partly broken away, also showing a drill in place in the stand;

Figure 4 is an end view of the drill stand; and

Figure 5 is a partial bottom plan view showing a portion of a table of size equivalents desirably associated with the drill stand.

In the preferred form of the invention, the device includes a thin sheet metal base 10, substantially rectangular in shape. This base 10 is desirably slightly rounded at its corners as seen at 11, but may be otherwise shaped as well; and in this instance the base 10 is further provided with a downwardly extending edge or rim 12, which contributes to its rigidity without materially increasing its weight. At the mid-portions of its opposite short sides 13 the rim of the base is further provided with recesses 1 the purpose of which will presently appear.

A sheet metal top plate 15, similar in size to the base 10, is also slightly rounded at its corners as seen at 16, and is provided with an edge or rim 17 similar to the edge 12 of the base 10. This plate 15 is further provided with'two downwardly ofiset rectangular strap portions, of equal length, designated 18 and 18, integrally formed in one piece therewith, and equal in width to the recesses 14, with which recesses the strap portions are adapted to co-operate.

Midway between the base 10 and the top plate 15 is a third metal plate 19, having a depending rim 19 identical in size and shape to the base 10, and difiering therefrom only by the addition of a series of holes hereinafter referred to. Both the base 10 and the intermediate plate 19 are preferably metallically secured to the straps or

offsets

18 and 18 of the top plate 15 by soldering or spot welding or other equivalent means, the straps being secured, to the rims 12 and 19', the former at the lower ends of the onsets l8 and 18', within the depressions 14, and the latter at the mid-points of said ofisets, within the depressions 14', at the central parts of the ends of the respective plates, whereby the plates are held in amount of sheet metal employed in the construc-' tion.

The recesses 14 of the base 10 and the recesses 14' of the intermediate plate 19 serve to align their respective members with the offsets 18 and 18' of the top plate 15 during the welding process, and further enable the ends of the drill stand to be smooth, the straps 18 and 18' being flush with the outer sides of the several rim portions. since the depending rim portions 12 and 19' at the indentations or depressions present substantially straight faces against which the straight straps 18 and 18' abut.

The top plate 15 is provided with a plurality of holes 20 adapted to receive the various sizes of drills, and arranged in a series of parallel rows, in this instance four, the sizes of said holes decreasing or increasing by an increment equal to that by which the drills themselves differ between their consecutive sizes. The holes are further grouped conveniently according to the sizes of the drills, whereby the first row accommodates 12 drills, the second row thirteen, the third row sixteen, and the last row nineteen drills arranged in consecutive order from the largest size of this particular group to the smallest. The holes are preferably numbered by ordinals 21 which correspond to the respective sizes of the drills.

The intermediate plate 19 is supported midway between the base 10 and the top plate 15 and is likewise provided with a plurality of holes 22 arranged in a series of parallel rows, wherein the holes of a row in the centre plate 19 correspond in size and vertical alignment with the holes 20 of a row in the top plate 15, any pair of holes so aligned being of a size to receive a

drill

23 or 24 corresponding to the number appearing adjacent the hole of this pair located in the top plate 15. Drills inserted through the proper numbered holes come to rest on the base 10, which is not perforated.

The present drill stand is not limited to receive drills of the so-called number type, but is equally adapted to receive drills classified by fractional, or letter sizes or other classification, such as metric sizes or a combination of any of the above mentioned classifications. Likewise no limitation as to size of the drill stand is intended as the sizes and number of drills of a series of one classification may require more or less space than those of another.

I further provide on the under side of the base 10 a table 25 which may contain pertinent and useful information to the users of the device, such for instance as metric or decimal size equivalents; and I prefer to provide such table on the surface mentioned, where itv may be protected from undue wear or damage by means of the depending rim of the base plate, which thus forms a receptacle to house the table.

Considerable particularities of description, as

to materials, part details, dimensions, capacities and utilities may have been herein indulged in, but it will be understood that these statements, made with particular reference to that one, and the one now preferred, of the many possible embodiments of the invention which is illustrated in the drawing, are not in any way to be taken as definitive or limitative of the invention. Inasmuch as many changes could be made in the above construction, and many apparently widely different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing. shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language contained in the following claims is intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, mightbe said to fall therebetween.

In other words, the scope of protection contemplated is to be taken solely from the appended claims, interpreted as broadly as is consistent with the prior art.

What is claimed is:

1. A drill stand formed of sheet metal and including a top plate, a centre plate and a base plate, said top plate and centre plate having a series of vertically aligned apertures adapted to receive a plurality of drill bits and the like, said base plate constituting a rest for said drill bits, said top plate including integral strap portions downwardly projecting at opposite ends and metallically joined to said centre plate and to said base plate to maintain all said plates in spaced relation, and said base plate and centre plate having depending rim portions indented at opposite ends to receive said strap portions in substantially flush relation with the outer ends of said depending rim portions.

2. A drill stand formed of sheet metal and including a substantially rectangular top plate, a substantially rectangular base plate and a substantially rectangular centre plate, said top plate and centre plate having a series of vertically aligned apertures of progressively difl'ering size adapted to receive a plurality of drill bits and the like, said base plate constituting a rest for said drill bits, said top plate including a downwardly projecting rim portion extending around the top plate and a strap portion downwardly projecting at each of two opposite ends and integral with said rim portion, said centre plate and base plate having depending rim portions indented at opposite ends to receive said strap portions to maintain all said plates in spaced relation, said strap portions being joined to the rim portions of said base and centre plates, whereby said strap portions are retained within the indented rim portions in substantially flush relation with the outer ends of the latter.

3. A drill stand as set forth in claim 2 in which the indented rim portions at opposite ends of the centre and base plates are formed with substantially straight faces, and the downwardly projecting strap portions are straight and abut against the respective rim-faces at opposite ends of the stand.
