TOOL-HOLDER.

Specification of Letters Patent.

Patenten Nov. a, 1909.

Application filed August 6, 1909. Serial No. 511,589.

To all whom i 'may concern.:

Be it known that I, VVlLLIAM A. PECK, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented a certain' new and useful Improvement in Tool- Holders, of which the following is a specification. Y

The invention relates to holders for containing a plurality of small tools, as screwdriver bits, awls and the like, and presenting the desired tool or bit for service, and the object of the invention is to provide a compact, easily operated holder or magazine in which a number of tools are contained, with means for presenting either of the tools, re'- liably held for use, and for permitting a quick interchange of suoli tools from the magazine to the position for service.

The invention consists in certain novel features of arrangement and details of construction by which Vthe above objects are attained, to be hereinafter described.

The accompanying drawings form a partof this specification and show an approved forin of the invention as applied to aplurality of screwdriver bits.

Figure 1 is a plan view. Fig. 2 is a side elevation. Fig. 3 is an elevation of the rear end. Fig. 4 is an elevation of the front end. Fig. 5 is a longitudinal central section partly in plan view, the plane of section being the line 5 5 in Fig. 3. Fig. 6 is a corresponding axial section, at a right angle to the preceding figure, taken on the line 6 6 in Figs. 3 and 5. Fig..7 is a cross section on the line 7 7 in Fig. 6.

Similar letters of reference indicate. the same parts in all the figures.

is the handle which may be of general cylindrical form adapted to serve with a screwdriver blade or bit, having a flattened tube B of metal fitted axially therein and projecting at the front. The hollow interior of the tube is of rectangular cross-section and serves as a channel b for the reception of a series of screwdriver bits C inserted end-to-end therein with their body portions C1 of uniform size and matching thereto. The tube B is of such length, and the bits so proportioned. relatively thereto, that when the channel is filled with the bits in contact each with the. next, one bit extends beyond the tube at the front end in position for service. bit is subjected are received and resisted by The torsional strains to which such the rectangular tube. At the rear end of the tube B, on one of its flat exterior faces, is mounted a flat spring D secured to the tube by screws or rivets D2 D2 and having its free end bent at an approximately right angle to form a flange or lip D1 partially coverinor the rear opening of the tube, serving as the entrance to the channel; the edge of the lip is beveled or chamfered as at d and the opposite edge of the tube is also rounded as atl b1 to permit the bits to be introduced one after the other into the channel by forcibly raising the lip D1 in the act of entering the bit, the interior of the handle being recessed at a to permit the spring to rise correspondingly. Thus constructed the end thrust. on the .exposed bit when in use is transferred through the succeeding bits and is received on the. lipl D1 which with its spring D is strong' enough to resist. sui-.h strain.

As shown.. the points ofthe bits are ot different widths as may be required for different sizes of screws or other conditions; to protrude any desired bit contained in the maga-zine or channel, the exposed bit is withdrawn from the front end and entered point tirst. at the rear, and pressing against the rearmost bit moves the entire series forward in the channel, causing the second bit to be protruded at the front, this operation is repeated until the desired bit is presented.

ln order to prevent the escape of the bits at the front end when the holder is reversed. means are provided for engaginvr the body of the exposed bit and holding 1t in place. Any suitable gripping device may be employed but the means shown is preferredfor the reason that it also aids in resisting the end thrust to which the exposed bit is subjected. 1t consists of a leaf or flat spring F attached to the exterior ofthe tube B at the front and having a dog F1 on its under face extending through a hole b2 in the wall of the tube into the channel and enga ed in a hole or recess c in the body portion 1 of the bit. The set of the spring F tends to lift the dog out of en agement and it is held in such engagement y a slide or collar G encircling the ,front end of the tube and inclosing the spring, which when forced forward depresses the dog into engagement and when retracted permits the spring to rise and release the bit in making the interchange from one size to another.

Each bit is provided with arecess c prop erly located to receive the dog, and-.the lat-v `ter is beveled at the rear to facilitate the F2 F2 projecting laterally to prevent the collar or slide G passing over the end of the tube. The rear end of the spring F is receivedin a recess in the handle and 1s thus held and reinforced in addition to the fastening screw or rivet F5. H is av errule serving as a finish for and to strengthen the front end of the handle.

The bits are preferably of uniform length with the recesses o uniformly located so that each will be properly presented for 0engagement with thedog F1 irrespective of the order in which they are introduced to the ma azine.

he whole forms` a small compact tool, easily carried in the pocket and having sutilcient strength and ran e for general service.

Althou h the tool 1s above described as adapted or screwdriver bits it will be understood that awls, boring bits, or other articles may be substituted.

The cross-sectional form of the channel may be varied as may the sizes and proportions `of the parts, and the number of bits.

yI claim 1.In a magazine tool-holder, a tube, a plurality of bits matching thereto and lying end-to-end therein in series, the bit at one end projecting beyond said tube, and means for holding said bits in said tube and resisting end thrust and torsional strains thereon.

2. In a magazine tool-holder, a tube forming a continuous channel of angular crosssection, a plurality of bits ofcorresponding section matching said channel and lying endto-end therein in series, and a yielding closure at one end of said tube, arranged to permit the introduction of said bits successively.

3. In a magazine tool-holder, a tube forming a continuous channel of angular crossf section, a pluralit of bits of corresponding.'l

cross-section matcing said channel and'ly# ing end-to-end therein in series, with the bit at one end projecting beyond said tube, means at said end for holding such projecting bit against endwise movement, and a yielding closure at the opposite end of said tube, ar-

ranged to permit the introduction of said bits successively and to resist thrusting' strains thereon.

4. The magazine tool-holder described,

A releasing said projectin comprising' a tube of rectan lar cross-section formingnal continuous c annel, a'seriesA of bits matc g such channel and lying 1n end-to-end contact therein with the bit at l one end pvgojecting` beyond said tube, means at said end for holding such projecting bit against forward movement, a spring secured to said tube atv the o site end and having a lip servin as a yielding closure for such opposite en and receiving rearwardly directed thrusting strains delivered thereto through said series.
