3 Claims. (Cl. 7l4.1)
This invention relates to wiring tools and more particularly to such tools including means for cutting an insulated wire to a specified length and for stripping the insulation from a portion thereof.
Devices of the general type to which this invention pertains are disclosed in the patent to H. A.'Miloche, No. 2,682,063, issued June 29, 1954 and the patents to Frank Reck, No. 2,743,502, issued May 1, 1956, and No. 2,765,684, issued October 9, 1956. In the above-noted patents means for cutting the wire and for mutilating the insulation in preparation for stripping are combined with means for Wrapping the stripped wire on a terminal in what is now termed a combination wire wrapping tool.
It is an object of this invention to simplify the structure of a combination wire wrapping tool and to facilitate its operation. A further object is to provide a combination tool in which all operations are performed solely by the rotation of a spindle member within a stationary sleeve.
One feature of the tool of this invention resides in the stationary sleeve member for anchoring the insulated wire. Another feature is the configuration of the sleeve member which enables passage of the insulated wire between the sleeve and spindle as the latter rotates, and further enables facile ejection of the stripped insulation.
A further feature lies in the arrangement and construction of the insulation cutting and wire guiding means.
The invention and its further features and advantages will be comprehended for clearly from the following detailed description taken in conjunction with the drawing, in which:
. Fig. 1 is a general perspective view of the assembled tool with a leng h of insulated wire loaded preliminary to wrapping a connection;
Fig. 2 is a perspective view of the stationary cutter member;
Fig. 3 is an end view of the head of the tool showing the wire in the loaded position before the commencement of the skinning and wrapping operation;
Fig. 4 is a similar end view showing the skinning action of the tool after a partial rotation of the spindle;
Fig. 5 is a perspective view of the head end portion of the sleeve member; and
Fig. 6 is a similar view of the spindle member showing a part of a terminal member upon which a portion of the skinned wire has been wrapped.
Referring to Fig. 1, the tool of this invention consists of three cooperating members: the fixed housing or sleeve 9, the stationary cutter member 10, and the rotary spindle 11. The sleeve member 9 tapers from the enlarged section containing the stationary cutter member 10 to a trough-like portion 12 and terminates in the head portion 18. The stationary cutter member 10, shown in Fig. 2, is a semicylindrical body fitting snugly within the sleeve 9 and fixed thereto by means of a locking screw, not shown, which may advantageously be placed in a hole through the underside of the sleeve into a tapped hole in the stationary cutter member 10. The
stationary cutter member 10 has a circular portion 13 containing the Wire cutting slot 14 and a flat portion 41 which provides a clearance space for the insulated wire inserted through the cutting slot 14. The rearward portion 42 is cylindrical and fits snugly within the sleeve 9. A central bore 43 through the stationary cutter member 10 provides a bearing for the spindle 11.
Thus, the spindle 11 rotates within the center bore 43 of the stationary cutter member 10 by means of rotative effort applied to the boss 17 on the spindle shaft. As indicated above, the circular section 13 of the stationary cutter member 10 includes a cutter slot 14 having a knife edge for cooperating with the rota-ting cutter 15 to sever the wire 20 to a predetermined length suitable for making the wrapped connection.
The head portion 18 of the sleeve, as shown in Fig. 5, has a reduced internal diameter forming the shoulder 30. Shown in Fig. 6 is the spindle head 34 which fits within and cooperates with the sleeve portion 18 of Fig. 5. For this purpose the collar portion 28 of the spindle head 34 of Fig. 6 engages the shoulder 30 shown in Fig. 5 and rotates within the portion 29 of the sleeve head 18. Thus, as shown in Fig. 1 the spindle 11 is retained between the shoulder 30 and the cutter face of the stationary cutter member 10 against which the rotating cutter 15 bears.
As shown in Figs. 1, 3, 4, and 5, the sleeve head contains a loading slot 19 and two wire anchoring slots 21. The spindle head is provided with an insulation cutter 25 in a cut-away portion of the collar 28 and a center bore 26 for receiving the terminal 27 upon which the wire is to be wrapped.
The skinning and wrapping functions of the tool of this invention are accomplished by the spindle and sleeve head portions and the cooperation of the respective parts thereof will be apparent from a description of the wrapping operation.
Preparatory to making a connection the insulated wire is loaded, as indicated in Fig. l, with the wire portion 20 which is fed into the cutting slot 14 along the spindle, into the slot 19 of the sleeve head 18, and into one of the anchoring slots 21. The initial rotation of the spindle 11 results in the revolving cutter 15 forcing the wire 26) against the cutting edge 14, severing the wire to a predetermined length. During the remainder of the spindle rotation the insulated portion 20 is carried around with the spindle 11. For this reason the clearance space 22 between the spindle 11 and the sleeve portion 12 is sufficiently great to enable passage of the insulation therethrough.
The end view of Fig. 3 shows the relative position of the wire 20 in the loading slot 19. As viewed from the terminal end, counterclockwise rotation of the spindle carries the insulated wire to a position between the surface 23 of the spindlehead and the surface 24 of the sleeve head 18. The slope of these surfaces is such as to force the wire into the cutting notch 25 to a position as shown in Fig. 4. As indicated in Fig. 4, the clearance between the inner wall 32 of the sleeve head and the insulation cutting surface 25 is sufficient to pass the Wire but not the insulation thereon. The insulation is thereby positively forced into the cutter and crushed for a considerable portion of its circumference.
As the spindle head revolves about the stationary terminal 27 the insulated wire portion 33 of Fig. 6 is held by the anchoring slot 21, thus drawing the free end portion 20 of the wire over the insulation cutting notch 25, thereby skinning the wire which is then wrapped about the terminal 27.
The facility with which a wrapped connection is accomplished by the tool of this invention will be indicated by a review of the steps involved. Loading the wire is a readily performed operation comprising placing the wire in theanchoring slot 21, the loading slot 19, and the cutting notch 14. The spindle 11 is then rotated while the sleeve 9 is held stationary. This may be accomplished by hand power or advantageously by portable power means applied to boss 17. Rotation of thespindlc cuts the wire to length, crushes the wire insulation in the cooperating means of the spindle and sleeve heads, and simultaneously withdraws the wire from its insulation sheath and wraps it around the terminal. It may be noted that where power means are used to rotate the spindle a single on-otf switch sufiices to control the operation of the tool. In addition, throughout the wrapping operation the connecting wire portion 33 remains securely anchored to the stationary sleeve, obviating any possibility of having the wire wrapped or entangled around a rotating spindle.
A further advantage in thus anchoring the wire is that the wrapping operation is, in effect, isolated from the connecting wire which is, therefore, not overtensioned, a feature of particular importance where the connecting wire path follows sharp bends around other terminals or dresser-s.
Although a specific embodiment of the invention has been shown and described, it will be understood that it is but illustrative and that various modifications may be made therein without departing from the spirit and scope of the invention. For example, it is apparent that the tool of this invention may be arranged for either counterclockwise rotation as shown herein or for clockwise rotation.
