l; Claim.

This invention relates to tool. handles and particularly to handles for tools of the push drill type in which a tool element is placed ina chuck secured at the end of the tool and the element caused to rotate in rst one direction and then the other when the handle of: they tool is pushed.

towards the working surfaceand allowed to return again to its normal position.

An object of the invention is to proviclea sturdy magazine handle for a tool with compartments for receiving a number of different tool elements, the tool elements being visible through the handle.

Another object of the invention is to provide a magazine tool handleA of the type described in which any one of a plurality of to-ol elements carried by the handlemay be selected quicklyand easily therefrom and the toolhandle maintainedv ready to receive the-tool element afterit has been used.

Another object of the invention is toprovide a magazine handle for a tool of thepush` drill type with a rigid, solid structure from theouter end of the handle where pressure isapplied to the rotation controlling mechanism.

Still another object of the invention is to pro*- vide a magazine handle for a tool of the push` drill type with a single rotatablemember to select the desired toolA element which is independent of the pressure transmitting portions of the handle.

The. invention accordingly. comprises thev fea:- 1i

tures of. construction, combinations of elements,

and arrangement of parts, which` will beexemplined in the constructions hereinafter set forth,

and the scope oi the application of which willbe indicated in the claim.

For. a fuller understanding of the nature and4 objects of the invention. referencesllould be had,

to the following detailed description taken in connection with. the accompanying drawings,` in which:

Fig. l is a side elevational View of a pushdrill embodying my invention;

Fig. 2 is a top View of thedrill.' shown in Fig. l;

Fig. 3 is an enlarged sectionalview ofthe main portion ofthe handle taken on the line 3-3 of' Fig. 7 is` an exploded View of the several parts forming the handle ofthe invention.

Although theY invention is applicable to any tool of the push drill type, such as screw drivers, reamers or the like, I have illustrated it in connection with a push drill.

My improved push drill, as shown in Fig, l, comprises a handle member it to the endof which is connected a tubular member I I into which the shank I2 carrying the chuck I3 is arranged to telescope movement of the shank I 2 into and out of the member II causes rotation of the chuck andvtool element when the tool is operated. The present invention is concerned with the magazine handle I0 and not with the operating mechanism of the tool which may be of conventional design.

The handle IIJ comprises a central core member I 4 which is rigidly secured in any desired manner on the endof a sleeve I5. The sleeve is provided at approximately its midpoint with a rib or bead I6 against which the core member I4 rests. The other end Il of the sleeve I5 is externally threaded to receive the tubular member I I which is` screwed.` tightly against the rib I6 and acts to hold the operating mechanism of the push drill in position upon the handle. The sleeve I5 is provided with internal helical grooves I8 which engage the helical ribs (not shown) on the handle ndlllif the shank I2 within the tubular mem- The core member Iii is hollow but has a solid ber, the lower end of the spring passing downV into the hollow core of the shank i2 to urge the shank andthe chuck I3 away from the handle. A central. rod2I of wood or other suitable material may be provided inside of the spring, with a nob 22. at the top thereof to separate the upper end of' the springfrcm the solid portion I9 of thecore member I4 and at the same time to prevent the spring from distorting sidewise. The shank l2 is prevented from being pushed out of the lower end ofthe tubular sleeve l! by the restricted end 23 ofthe tubular member I I which is smaller in diameter than the helical teeth on the shank 21.

AsV above, constructed, when the core memberl I4 is forced toward the chuck i3, the shank I2 will move into the sleeve IE and into the hollow interior of the core member against the tension of thespring 26. At the same time the helical ribs or teeth on the shank I2 will engage the helical grooves I8v of the sleeve I5 and cause the shank to rotate in a given direction. Release of the pressure cn the core I4 will permit the spring to force the shank outwardly and the helical teeth on the shank will cooperate with the helical grooves in the sleeve I5 to cause rotation of the shank in the opposite direction.

The core member I4 may be made of any suitable material and is provided with a plurality of longitudinal grooves 25, extending for approximately two thirds of the distance from end to end thereof. These grooves are spaced equally around the outside of the core, leaving webs or partitions 26 between them. I have shown the core I4 divided into nine equal spaces, with the grooves 25 occupying eight of these spaces and the ninth space left solid and provided with a hole 28 extending longitudinally a short distance into the material from the outer end of the core. This hole contains mechanism for a purpose to be later described.

The end 29 of the core I4, adjacent the sleeve I5, is cylindrical and has a diameter approximately equal to a circle drawn through the inner surfaces of the grooves 25. The ends of the partitions 26 taper down toward the end of the core. A quil1 32 of suitable material is provided with a circular opening 33 to t over the end 29 of the core member, the circular opening having a plurality of grooves 34 to receive the tapering ends of the partitions 26, the arrangement being such that the quill 32 will have a tight friction nt upon the end of the core member. It may be secured thereon in any other desirable manner. The end of the quill towards the core member is slightly larger in diameter than the overall diameter of the core member, and the outside of the quill is curved and tapered to a diameter at the other end which is slightly larger than the diameter 0f the bead I6 on the sleeve I5.

A shell 36 is provided to t over the core member I4. This shell is long enough to reach from the quill 32 to approximately the outer end of the core member and may be provided with a plurality of longitudinal grooves 38 to receive the outer edges of the partition members 26 and thus prevent the shell 36 from rotating. The outer surface of the shell 36 is preferably provided with a plurality of flat surfaces 36, there being one flat surface for each of the grooves 25 in the core member and one for the solid space containing the hole 28. This makes nine ilat sides, the intersections of which are aligned with the grooves 38 for the partition members 26. The shell 36 cooperates with the core member I4 to form a plurality of compartments formed by the grooves 25 and the partitions 26, and I preferably make the shell of transparent plastic material so that the tool elements 45 which may be contained in these compartments will be visible from the outside.

The central portion 42 of the core I4 is extendi ed slightly beyond the remainder of the core and is circular in cross-section to receive rotatably a disc 44 having an opening 45 in the center to ii't over the portion 42 and having an outer diameter which is slightly larger than the overall diameter of the shell 36. The outer edge of the disc is preferably milled, as at 46, so as to provide a gripping surface for the iingers to permit rotation of the disc manually with respect to the core member I4 and the shell 36. The disc is also provided with a hole 41, spaced from the central opening 45 so as to align successively with the grooves 25 in the core member I4 when the disc is rotated. The disc is also provided with a plurality of equally spaced indentations 48 on one side thereof, positioned the same distance from the center hole 41 which distance corre.-`

sponds to the distance of the hole 28 from the center of the core member 44.

A cap 50 is provided on the outer end of the handle to hold the disc in position. This cap may be rigidly secured to the core member I4 in any desired manner. I have shown for this purpose an extended portion 5I on the central portion 42 of the core I4 which is square in crosssection and is adapted to fit into a square opening 52 centrally located in the cap 50. A screw 53, the head of which seats in a counter-sunk opening 54 in the cap, passes through a central hole 55 therein and engages a tapped hole 56 in the outer end of the core I4. The inner surface of the cap 50 is arranged to permit clearance between th cap and the disc 44 when the screw 53 is tightened, so as to secure the cap 5D rigidly against the core member I4 but permit the disc to rotate.

By this arrangement the disc 44 may be rotated by manual engagement of the milled surface 46 thereof without rotating either the sleeve 36 or the cap 5U which remain rigidly connected together. The cap 5l) is provided with a plurality of holes 58 spaced in a circle around the cap at the same distance from the center thereof as the hole 41 in the disc 44 is spaced from the center of the disc. There is one of the holes 58 for each of the compartments formed by the grooves 25 in the core I4 so that there are eight holes with one large space. The holes are aligned with the compartments and the space with the hole 28.

A plunger 68 is provided in the hole 28 and has a conical outer end 6I. A spring 62 is compressed between the plunger and the inner end of the hole 28, so as to urge the plunger against the disc 44. When the hole 41 in the disc is in alignment with the hole 28 in the core, the pointed end 6I of the plunger 60 extends up into the hole 41. However, the plunger is prevented from moving upwardly any farther by the solid portion of the cap 58. This engagement of the plunger with the hole 41 holds the disc 44 in position with all of the compartments, formed by the grooves 25, closed by the disc, but a little extra rotational pressure on the edge of the disc will cause the plunger to compress the spring as the edge of the hole 41 in the disc rides over the conical end of the plunger. The disc may then be rotated to align the hole 41 with any one of the compartments formed by the grooves 25, and as this is done the plunger is forced upwardly, snapping into each of the indentations 48 as the particular indentation passes over the plunger. When the hole 41 is aligned with the desired compartment, one of the indentations 48 is aligned with the plunger which moves upwardly into the indentation and holds the disc against accidental movement.

In the operation of the push drill described to illustrate the invention, a plurality of drill elements 48 are positioned in the compartments of the magazine handle. When it is desired to use one of these drill elements, the disc 44 is rotated until the hole 41 is aligned with the hole 58 corresponding to the compartment which contains that drill element. In order for the operator to know that the hole 41 is thus in proper alignment, I provide a notch 66 on the edge of the disc 44 adjacent the hole 41, which notch may be given a contrasting color, if desired, so that the operator need only rotate the disc until the notch 66 aligns with the particular drill element, as viewed through the transparent shell 36. The

indentation 48 on the disc, which is then over the plunger 60, will receive the end 6I of the plunger, to thus position the disc so that the hole 41 is in proper alignment with the compartment and with the corresponding hole 58 in the cap t. By tipping the tool so that the handle is pointed downwardly, the particular drill element may be moved by gravity from its compartment in the handle and then inserted in the chuck I3 for use.

While the drill is being used, the handle is grasped by the ngers with the heel of the hand pressing against the cap 50. Since the cap is rigid with respect to the core member I4 and also with respect to the shell 36, there will be no tendency for the disc 44 to be rotated, and after the tool has been used, the notch 66 in the edge of the disc will still be found to be aligned with the compartment from which the tool element was removed and will indicate the position of the compartment. Therefore, the tool element can be returned to its proper compartment with the greatest of ease and the disc rotated again to bring the plunger 6B into engagement with the hole 41 which thus locks all of the compartments so that the tool elements cannot be removed.

It will be seen from the above description that I have provided a magazine handle for a tool of the push drill type which permits the tool elements carried thereby to be clearly visible at all times and by means of which any one of such tool elements may be removed easily and quickly for use in the drill, while the compartments from which it was removed will be left open during the use of the tool, so that the tool element may `be just as easily returned to its proper compartment, without the necessity of any additional adjustment of the handle parts. The rigid construction of the cap and core member permit hard usage of the tool Without damage to the moving disc which controls the selection of the tool elements.

Since certain changes may be made in the above construction and 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 drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claim is intended to cover all of the generic and specic features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

A magazine tool handle comprising a handle member, a, plurality of compartments arranged longitudinally in said handle member with openings in the end thereof equally spaced from the center thereof, a cap member, means rigidly to secure said cap member upon the end of said handle member, means to space the outer edge of said cap member from the end of said handle member to form an annular groove around the end of the handle, said cap member having a plurality of holes spaced at an equal distance from the center thereof and arranged to align with the openings of said compartments when said cap is secured to said handle member, there being a separate hole for each opening, a ring member rotatably mounted in the groove between said member and cap, said ring member having one hole therein which is adapted to align successively with the openings of said compartments when said ring member is rotated, and resilient means to retain said ring member with the hole aligned with any one of said openings or, alternatively, in a position where it is not aligned with any of said openings, said ring member being lightly larger in diameter than said handle member and said cap whereby said ring member may be manually operated.
