Application July 24, 1946,.Serial No. 685,996

bularlcasing providing a "housing for the various detachable implements and having an elongated cut-away portion intermediate its ends which is normally closed by aremovable. coveriormed to complete the tubular wall, a fixed, axially bored plug which with a spring loaded plunger movable radially in the plug provides a chuck in one end of the casing, and a ring-shaped member rotatable on the plug. and cut back from its inner edge to .form a segmental portion overlying the outer end portion of the cover, an object of the invention being to employ this ring-shaped member by rotary movement as a common means for first locking the cover in position on the casing and then operating the chuck to grip an implement inserted therein.

Another object of this invention is to provide an improved hand tool which will be relatively inexpensive to manufacture, simple in contruction, of a minimum number of parts, pleasing in appearance, compact, and very efficient and durable in use.

With these and other objects in view, which will appear as the description proceeds, there has been illustrated in the accompanying drawings a form in which the features and principles of this invention may be conveniently and practically embodied.

Figure '12 is a broken sectional view taken 'on 'the lines l2l-2 of Figure 11 Figure 13.15, a cross-sectional view'taken on the line l3-l3 of Figure 6;

Figure 14 is an end view of the tool clamped handle .and easing cover securing ring; and

Figure 15-is 'asideview of the said ring. Referring 'now to 'the drawings wherein like reference numerals designate like parts throughout the several views, the numeral l l denotes the tool 'handle in its entirety, and the numeral l2 denotes a device in its entirety which maybe detachably secured to the handle I I. The handle ll comprises a hollow cylindrical casing I3, having a detachable cover l4,v and a detachable hollow cylindrical end closing member IS. The cylindrical .handle casing I3 is open at one end to be closed by the member I5 and is closed at its other end by an implement shank receiving plug IS. The casing I3 is cutaway the greater part of its length intermediate its ends parallel with its axis and the cover I4 is formed "to cover this opening and to complete the cylindrical form. One end I! of the casing 13 is onehalf cylindrical in form and embraces a reduced end [8 of the plug I6, being secured thereto by soldering or brazing. The other end IQ of the casing I3 is completely cylindrical in form and embraces .a reduced end H of the cylindrical end casing member IS.

The cover l4 has a reduced end portion, or lip, 22 adapted to slip under the end portion IQ of the casing l3. A ring 23, embracing the plug I6 and the casing end I1, is cut away at 24 to allow the cover I4 to be disposed in position in the cutaway of the casing 13 and is rotatable about and upon the casing end I! and plug IE to dispose the remaining lip portion 25 of the ring 23 over the end of the cover I4. The combined action of disposing the cover lip 22 under the casing end I 9 and disposing the ring lip 25 about the end of the cover I4 will detachably and firmly secure the cover M to the casing [3.

The ring 23 is provided with a slot 26 in its ,full diameter portion to receive a nubbin end 21 of a plunger 28 mounted for radial movement in .a counterbore '29 in the plug IS. A spring 3| constantly urges the plunger 28 outwardly by reacting between a shoulder 32 on the plunger and the bottom of the counterbore 29. The nubbin end 21 of the plunger 28 detachably secures the ring 23 on the plug I6 and easing end ll and limits the rotative movement of said ring thereon in both directions by engaging. the ring at, the ends 3.3 and 34 of the slot 26. The ring 23 also has a hole 35 providedlthereinspaced from the end 33 of the slot 26, to allow a screw threaded end 36 of a hammer implement 31 to pass therethrough and be screw threaded into a thre'adedhole 3'8' formedin the plug I6, see Figure 5; The-plug IB is-of metal and aets 'with" the implement 31 to provide a weighted end for the tool to facilitate use of the same as a hammer.

The plug |6 functioning as a chuck is provided with an axial hole 39 which is generally circular in cross-section and has a flattened portion 4|. The hole 39 is adapted to receive the shanks 42 of the various implements which shanks are generally circular in cross-section and each having a flattened portion 43. The plunger 28 extends through the plug l6 into the hole 39 therein at the flattened portion 4| to have its end 44 engage against the flattened portion 43 on the shank 42, of the implement selected for use, to secure it to the handle As some of the implements require attachment to the handle against lengthwise movement relatively thereto, the shank 42 is also provided, at its flattened portion 43, with a cross groove 45 into which the plunger end 44 will seat.

The plunger 28 is pressed inwardly to cause its end 44 to clamp the implement shank 42 in the plug I6 by rotating the ring 23 on the plunger 28 to dispose the nubbin end 21, of the plunger 28, under the ring 23 in a shallow groove 46 formed in the internal peripheral surface of the ring beyond the slot end 34, see Figure 8. R- tating the ring 23 to dispose the nubbin end 21 beyond the end of the groove 46, see dotted lines in Figure 9, will press the plunger end 44 into the cross-slot 45 in the implement shank 42.

The arcuate portion 41 of the casing remaining after being cut away is provided with a multiple clip 48 formed from a strip of sheet metal by corrugating it to form

loops

49, and 52. The base portions of the

loops

49, 5|, and 52 are secured, as by soldering, or brazing, to the internal surface of the casing portion 41 and the outwardly extending arm portions of these loops are adapted to spring press against the sides of implements such as a tack puller 53, a pair of pliers 54, and a can opener 55, see Figures 6 and 10. The arcuate cover I4 is also provided with a clip 56 having a loop 51 in which the hammer shank 36 may be held. The ends of the clip 56 are secured to the internal surface of the cover l4 and the clip is tensioned to provide a portion 58 adapted to clampingly hold an implement such as a flat file 56 between it and the cover l4, see Figures 7 and 10. The outer peripheral surface of the cover M is provided with indicia in the form of a four-inch scale 6|, see Figure l, for use in laying out work, etc.

The casing end closing member I5 is detachably secured to the casing portion l3 by having the reduced end 2| thereof provided with diametrically opposite L-shaped slots 62 each arranged to receive a pin 63'secured to and extending inwardly from the cylindrical casing end I9, see Figures 11 and 12. One end of the L slot opens at the end of the member l5 to receive the pin 63 when the reduced end 2| of the member |5 is moved axially into the casing end l9 and the other portion of the L-slot extends peripherally along the reduced end 2| to lock it to the casing end l9 when the member I5 is rotated relatively to the casing.

The member l5 has a thickened end 64 at its outer end and from this end 64 a tube 65 axially extends to its open end. The thickened end 64 is provided with a concentric hole 68 to receive the reduced end of a flash-light bulb 61. The threaded metallic contact shell 68 of the bulb 61 has a coiled spring 69 threaded thereon which extends outwardly from the shell 68 to contactingly engage the end edge of the metallic shell 4 H of a dry cell 12 disposed in the tube 65 and, by spring tension reacting between the cell 12 and the bulb 61, to normally maintain a bulb contact stud 13 and contact stud 14 of the cell 12 out of contact. A plug 15 is disposed in the outer end of the tube 65. The plug 15 has a nubbin 16 extending outwardly therefrom by which the cell 12 may be pressed against spring tension to cause the

contact studs

13 and 14 to be engaged to energize and light the filament of the bulb 61.

Radiating from the tube 65 from its outer periphery to the inner periphery of the member |5 are a plurality of partitions ll separating this space into compartments 18 into which various implements may be placed. For instance in one compartment is a chisel T9 and in another a gouge 8|. A saw blade 82 and another implement 83 such as a brush is disposed in another of the compartments. Figure 13 shows the shank ends of these and other implements which may consist of drills, rat-tail file, reamers, etc., disposed in the compartments 18. A flat ringshaped cover 84, having a broken-away portion 85 is disposed over the open end of the compartments 18 and encircles the outer end of the tube 65. The ring-shaped cover 84 may be retained in place by spinning the outer edge of the tube 65 over upon the outer surface of the cover 84. The cover 84 is arranged to resolve about the tube 65 to uncover any of the compartments 18 from which it is desired to remove an implement, after first removing the saw blade 82, which, when in place, serves to prevent the cover 84 from revolving to uncover the compartments.

The plug 15 is retained in the tube 65 by a ring 66 which encircles the nubbin T6. The ring 86 has a tab 81 extending radially therefrom over the ring-shaped cover 84 to be attached thereto by a screw 88. The ring 86 is spring tensioned and, when the nubbin i6 and plug are depressed to cause the

contacts

73 and 14 to engage and energize the bulb filament, may be rotated on the screw 88 to overlie the nubbin 16 to hold the contacts 73 and T4 in engagement and the bulb lighted. The flashlight can only be actuated when the member I5 is detached from the casing portion l3, although after lighting the bulb the member l5 may be again attached to the casing for convenience in holding it.

The open slot 26 and the internal groove are in the axial plane of the plunger 28, the rounded outer end 21 of which always engages in one or the other and thus retains the ring member 23 against axial displacement. As the lip 25 disengages the cover |4 rotation of the ring in one direction is positively stopped by engagement of the end 33 of slot 26 with the nubbin 21. In order, however, to permit further rotation of the ring in the opposite direction, after engagement of the slot end 34 with the nubbin 27, the inner surface of the ring at the juncture of the groove 46 and slot 26 is slightly chamfered. This provides a slight cam surface which permits the rounded nubbin end of plunger 28 to ride under the ring into the groove 46 thus forcing the plunger 28 into operative position against action of the spring 3|. The relative circumferential positioning of the lip portion 25 of ring member 23 and the slot 26 is such that the cover I4 is always secured against removal during move- 1212:3111, in or out of the implement locking plunger The hand tool above described is particularly useful and practical, various implements always being available for general repairs in the home, shop, automobile, or boat. Due to the novel arrangement of the implement holding means, all

of the implements may be carried by the casing in a convenient manner and be readily available. The member I adapted for use as a flashlight and implement holder also forms an end closure means for the casing l3 and assists in retaining the cover I4 in place. The ring 23, while acting as cover 14 retaining means, is also adapted to clamp the various implements to the casing 13 in the plug [6 through the plunger 23 which, in turn, acts to retain the ring 23 in place by extending through the slot 26.

Due to the provision of the above described novel features, a particularly useful, practical, and efiicient hand tool is provided.

While there has been shown and described herein one form of hand tool in which the features and principles of this invention may be embodied in practice, it is to be understood that the same may be embodied in other specific forms without departing from the spirit and essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the claims rather than to the foregoing description to indicate the scope of the invention.
