ers for reels, of which the reuwggg specification. p

This in n nre a es teah lesr .fertq 'l such for instance as the like commonly used as an extension bit by electricians to carry an auger or boring toolv used in the making of holes for electric wires or conduits; and the object of this invention is to provide an improved form of one-piece binding nut or member which may be readily applied to the shank of the tool and screwed into the holder member to bind the head of the tool in its socket in the holder.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings.

Figure 1 is a sectional side elevation showing the holder with the head of a tool bound in the socket portion thereof by means of my improved form of binding nut.

Figure 2 shows the holder partly in section with the nut and tool removed.

Figure 3 is a view illustrating the helically shaped groove or opening in the nut and illustrating the angular position the nut must take in being applied to the shank of the tool.

Figure 4 is a side elevation of my improved nut showing the helically formed opening therein.

Figure 5 is an end view sectioned on line 55 of Figure 4, looking in the direction of the arrows and illustrating the extent of circular bearing of the threaded portion to be a large portion of a complete circle, which is due to the angularity of the cut through the same.

It is found in practice of advantage in the construction of devices of this character where a nut is to be applied to the reduced shank portion of a tool having enlargements at either end, to provide a bearing for the threaded portion of the nut as nearly a complete circle as possible to obtain. the maximum binding elfejctof the nut and at the sametiine forn'rfthe nut-of a single'pi ece of metal, whereby" it be quickly" positionedonf-th'e. shank of the tool and screwed into the holder 'to, bincl the tool in its socket and i as readily removed when-"it is desired to withdraw thei'too'l from-=its socket and the folltiwiiig' i's' 'a detailed-- description o' f'one construction of nut by which these advantageousresults may be accomplisheda T With lreference to the drawings, '10 designates the body member of the holder which is provided with an inner angular socket 11 and is-threaded at 12 at its outer end beyond the socket portion. This body is permanently connected to the extension bar 13 which may be of any suitable length to meet requirements.

This device is particularly constructed to receive the enlarged, tapering head end 15 of a bit or auger 14:, which bit ordinarily has a screw shaped cutting end, and in order to bind this head portion in the socket portion 11 of the body member, it is found to be necessary and desirable to apply a nut 16 to the smaller shank portion of the tool and screw it into the body to bind the bit in position therein and in order to apply this nut to this reduced portion, it is necessary that this nut shall be either slotted or made in halves to receive the reduced shank of the tool. Applicant has found it of particular advantage to form the nut in one piece and in tubular form and has found it i of especial advantage to provide an opening throughout the length of the side wall of this nut formed in helical shape as at 18,

whereby in applying the nut to the shank of the tool it must be set at an angle to the axis of the tool, as illustrated in Figure 3, thereby permitting the tool shank to be readily passed through the slot and into the' bore of the nut and by this construction it will be seen that when the nut straightens out on the shank and enters the holder as struction the threaded portion of the nut has a bearingmore nearly its entire circumference than can possibly be the case where the out is in a straight, line.

The inner end of this nut is formed to engage the shoulder 200i the tool to bind the head of the tool firmlyin its socket and the outer portion 21 of this nut is enlarged to be readily engaged by the thumb and finger of the operator to set it tightly into its binding position and to quickly remove the same when desired.

My improved form of binding nut is very simple in construction and efiective in its action and by its use a tool may be firmly bound in the socket of the holder and retained while the tool is being operated.

The foregoing description is directed solely towards the'construction illustrated,

internally screw threaded andformed with Y a socket seat to receive the end of a tool shank, and a threaded cylindrical retaining nut having a helical opening through its sidewall for the reception of the tool shank and adapted to be screwed into said body to bind thetool shank in its, socket seat.

2. A tool holder having a hollow body v portion internally screw threaded and having a socket formed beyond the threaded portion shaped to receive and fit the end of e the tool, and a screw threaded cylindrical sleeve having a helically disposed opening throughout its length .for the reception of the tool shank and adapted to be screwed into said body, its inner end being adapted to engage the shoulder under the head of the tool to force it to its seat in said socket and the outer end of said sleeve having, an engaging portion by which it is manipulated.

In testimony whereof I aflix my signature.
