This invention relates to drill cases and deals more particularly with cases for storing a set of drills of graduated size whereby they may be displayed for selective removal and carried without fear of dislodgement.
A set of drills usually 'runs' sixty in number. APrevious attempts to store such a number of drills resulted in a packagey box, or case of some oonsiderable bulk` with the added disadvantage of piece-meal access to only a portion of the drills in the set. Certain of the previous structures were so designed as to entail the necessity of inverting the package, box or case to dislodge the drills therein so that a selected one may be removed. Frequent spilling of the contents resulted. Other structures were so designed as to4 have the drill set arranged in separate groups or rows where access to a back row could be had only by first removing the front rows. Still other structures incorporated a drill stand in cavities of which the drills were set, the stand and drills being placed in a oase to obviate inadvertent dislodgement of the drills.
Recognizing the faults of the prior known structures, this invention seeks to provide an improved drill case in which the drills are held against inadvertent dislodgement when said case is in folded condition and which when opened, displays all of the drills for equal access to any of them.
The invention also seeks to provide a drill case in which the movement of the drills therein is limited to obviate rattling and undesired nicking and wear.
More specifically, the invention contemplates a compact, at case comprising hinged parts each designed to carry a number of drills, said parts being foldable for convenient carrying of the case and when unfolded, being adapted to be set upon any flat surface to provide a display rack giving ready access to any drill in the set.
The foregoing and many other objects, features and advantages of the invention will be set forth or will become apparent as the following detailed specification progresses. The accompanying drawing which serves as a basis for the specification, illustrates a preferred form of the invention as at present conceived.
In the drawing- Fig. 1 is a perspective view of a drill case, in folded condition, and constructed in accordance with the invention.
Fig. 2 is a vertical sectional view as taken substantially along the plane of the line 2-2 of Fig. 1.
Fig. 3 is a perspective View of the drill case in open condition and set up as a rack.
In that form of the invention which is illustrated in the drawing, the drill casevcomprises the parts 5, 6, and l, the parts 5 and 6 being hinged together as at 8 and the parts 5 and I being hinged together as at 9. The parts 5 and 6, when the case is folded, comprise the outer covers thereof, the part 'I being disposed therebetween.
The part 5 preferably comprises a side wall I0, end walls Il and I2, and a bottom wall I3. In a somewhat similar manner, the part 6 comprises a side wall I4, end walls I5 and I6, and a bottom wall I'I. Formed in this manner, the end walls II and I6 form one end wall of the case, the end walls l2 and I5 form the other end wall of the case, and the bottom walls I3 and I'I form the bottom wall of the case.
It will be noted that when folded as in Fig. 1, the parts 5 and 6 form a flat, compact and easily handled case. Means may be provided to maintain the parts in folded condition and may comprise a member hinged to one of said parts and adapted to be swung into interlocking engagement with the other of said parts. However, as shown, it is preferred to provide a separate locking part such as the part I8 which is provided with edge channel portions I9 for slidably engaging the flanges 20 provided along the upper edge of each part 5 and 6. This locking structure is best seen in Fig. 2. For easy manipulation of the locking part I8, it may be provided with a grasping handle 2|. It is evident, from Fig. 1 that the drill case is neat, at, and compact, and may be easily carried and stored.
The mentioned set of sixty drills is arranged in the case above formed in the following novel manner:
Each part 5 and 6, on the inner face of the walls I0 and I4, and the part 'I on one face thereof, is provided with means for holding drills. These drills are graduated in size and vary in length according to their size. Hence, the drill holding means are designed to hold the largest and longest drill at the left end (Fig. 3) of the part 5, and the smallest and shortest drill at the right end of the part 1, the remaining fifty-eight drills being held, in the order of their size and length between these two points.
The drill holding means on the part 6 preferably comprise the spaced channels 22 and 23, each identically formed with a series of holes 24 and 25 graduated in size from the largest at the left for holding drill size No. l, to the smallest at the right for holding, for instance, drill size No. 14.
The channels 22 and 23 are preferably positioned with respect to each other and to the top and bottom of the case so as to engage suitable intermediate portions of the drills set in the holes 24 and 25 thereof. The larger drills-No. 1 and 2, for instance, will rest upon the bottom Wall l1'. In order to have all of the drill tops substantially in line, an angularly disposed ledge 26 formed by an angle xed to the part 5, is provided to form a support for the bottoms of the remaining drills. The angle at which the ledge 26 is disposed is determined by the varying lengths of the drills which it supports.
In a similar manner, the part 5 is provided with drill holding means comprising the channels 2l and 28 having graduated holes 29 and 3i?, and the drill support ledge 3l. The channels and .ledge are arranged to support the drills, in this case sizes No. 15 to No. 32, so their top ends are substantially Valigned and in line with the drills carried by the part l.l
This construction is also carried out on the part l, the drill holding means comprising the channels 35 and 34 having graduated holes 35 and 35, and the drill supporting ledge 3l. This part `'I carries the smaller drill sizes from No. 33 to No. 60 in the same manner as above described.
Fig. 2 reveals the position of the drills in the case when said case is in folded condition, showing how the drills are held and limited in their movement. This gure, together with Fig. 1, villustrates the compactness of the device and the ease with which it may be handled. When a drill is to be selected, the top plate I8 is removed, the
three Darts 5, 6, and 'l opened as shown in Fig. 3 and set upon any flat surface. All of the drills are now exposed and ready of access. The danger of spilling the drills is practically nonexistent and contact which may cause nicks, obviated.
While the device disclosed deals with a drill case, it is obvious that it may be employed for burrs, bits or other elongated items. It is evident then that modifications of the invention may Well be made Without departing from the spirit and scope thereof as claimed.
, What I claim as new and desire to secure by Letters Patent is:
A case for drills and the like comprising a central part, a lateral part hinged at each side of said central part, said parts being adapted to be folded to form a case in which said central part and one of said lateral parts comprise the outer Walls thereof and said other lateral part being disposed therebetween, xedly positioned means on each part for supporting drills and the like in freely accessible condition, said means comprising a pair of spaced members each having graduated holes for receiving a row of graduated drills, and an angularly disposed member providing a support ledge for the bottoms of said drills, the high point of a ledge member of one part being in line With the 10W point of a ledge member of an adjacent part, and a sliding cover engaged With said central part and said outer lateral part for maintaining said parts in folded condition.
