In the manufacture of electrical apparatus such as is used, for example, in the telephone and radio art, a fiat'type of terminal l5, as illustrated in Figs. 7 and 14, is frequently used and in order to make an electrical connection therewith, a. connector wire [6 is wound in spiral fashion tightly around the terminal for several convolutions, and the junction is enclosed. in solder to provide an. effective and protected electrical connection.

' The winding of'the c'onnectorwire [6 about the terminal I5, which heretofore has mainly been a manual operation, may be greatly facilitated by the use of portable wire winding devices of the type herein disclosed.

Referring now to the embodiment of the invention disclosed in Figs. 1 to 6, the device is disclosed as a pistol type of winding tool comprising a housing 22 having a hand grip 24 extending downwardly therefrom. Secured in an aperture 26 (Fig. in a stationary boss 28 within the housing 22, as by means of a set screw 30, is one end of a stationary rod or shaft 32. The rod 32 extends outwardly through an aperture in the housing and is provided at its forward end with a rectangular recess 36 for receiving the end of the terminal I5 therein. A sleeve member 38 rotatably mounted on the stationary rod 32 is secured by means of a set screw 40 at its rear end in telescoping relation to a bushing M, which, in turn, is mounted for rotation on the rod 32 and within a bearing member 42 secured to the housing 22.

At its rear end, the bushing 40 means of a pin 44 to a bevel gear 46, which is freely rotatable on the rod 32 and meshes with a bevel gear 48 having a cylindrical hub 50, which is rotatably mounted in a bearing aperture in the bearing member 42. A pinion gear 52, secured to the bevel gear 49 for rotation therewith, meshes with a gear sector 53 mounted for movement about a pivot pin 54 and having an operating or trigger lever 56 extending therefrom through an aperture in the housing 22. The sector 53 is stressed for rotation in a clockwise direction about its pivot 54, as viewed in Fig. 1, by a spring 51, the rotary movement of the sector in this direction being limited by a stop pin 58 engageable with the arm 56. It will be apparent, from the description thus far, that, upon engagement and actuation of the lever 56 in a counter-clockwise direction, the sleeve 38 will be caused to rotate through a predetermined number of revolutions, and, upon disengagement of the lever 56, the spring 51 will serve to rotate the sleeve 38 in the opposite direction and restore it to its normal position, as indicated in Figs. 5 and 6 of the drawings.

At its forward end the sleeve 38 is provided with a longitudinal and radially extending slot for receiving a winding finger 62. The winding finger 52 is pivotally mounted intermediate its ends on a pin 64 and has its forward end 65 positioned slightly beyond the end of the rod 32. A spring 66 engaging the rearwardly extending portion of the winding finger 62 stresses the finger for rotation about the pin 64 to urge the forward end 65 into engagement with the end of the rod 32. Extending longitudinally of the winding finger 62 from the forward end 65 thereof is a recess or aperture 68 for receiving the connector wire 16 therein. The bore 66 is formed in the winding finger as by drilling while the forward portion of the winding finger is straight, and after the bore 68 has been formed, the forward end 65 may be bent radially inwardly as shown in the drawings.

To enable the end 65 of the winding finger 62 to move into close proximity to a terminal member I5 positioned in the recess 35 of the rod 32, portions of the forward end of the rod 32 are cut away forming pairs of oppositely disposed inclined surfaces '|0-10 and I2-'|2 arranged in rectangular formation about the rectangular recess 36. The inclined surfaces 19-10 and 12--12, in addition to providing clearance for is secured by the movement radially inwardly of the end 65 of the winding finger 62, form a cam track to guide the forward end 65 radially in and out, as the sleeve 38 and the winding finger 62 are rotated, to follow a rectangular path correspondmg generally to the rectangular cross-section of the terminal I5.

' In using this device the operator while holdmg the device in one hand inserts with the other hand the bared end of the connector wire I6 into the aperture 68 of the winding finger 62 as indicated in Fig. l and then moves the winding tool or device relative to the terminal to cause the end of the terminal to be positioned within the recess 36 of the stationary rod 32. The conductor wire I6 may then be bent downwardly, as indicated in Fig. 6, and held there while the operator engages and moves the lever 56 to actuate the driving mechanism and rotate the sleeve 38 and the Winding finger 62 through a predetermined number of revolutions, approximately three and one-half. As the winding finger 62 is revolved about the rod 32, the forward end 65 thereof will guide the bared end of the connector wire I6 about the terminal and, as successive convolutions are laid or wound on the terminal l5, they act to push the preceding convolutions longitudinally thereon so that, on completion of the winding operation, the end of the connector wire I6 will be Wound in a spiral form in tight engagement with the terminal and with the convolutions thereof in tight engagement with each other as shown in Fig. 7.

In the embodiment of the invention illustrated in Figs. 8 to 13, the Wire winding device is shown as being of the manually operated pistol type tool comprising a housing having a han-- die or pistol grip 9|. A rod or shaft 84, secured in a recess in a member 86 (Fig. 12) formed as a part of the housing 80, extends outwardly from the housing and, at its forward end, is provided with a recess 88 for receiving one end of the terminal member I5, as illustrated in Figs. 10-13. A barrel or sleeve 90 is rotatably mounted on the shaft 84 and is provided, at one end, with an enlarged aperture for telescopingly receiving therein a bushing 9|. Pins 92-92, fitting in apertures 93, and longitudinally extending slots 94 in the bushing 9| and the sleeve 90, respec-- tively, operatively connect the sleeve 90 for rotary movement with and for axial movement relative to the bushing 9|. The bushing 9| has fixed thereto, as by being pressed therein, a bevel gear 95, which meshes with a bevel gear 96 mounted for rotation in a bearing member 98. Fixed to the bevel gear 96 for rotation therewith 1s a gear I00, which meshes with a gear sector IOI mounted for oscillating movement about a pivot pin I02. The sector IOI has an operating arm I04 extending outwardly from the housing 80 and is stressed for rotation in a clockwise di rection, as viewed in Fig. 8, by a torsion spring I06, and a stop pin I01 serves to limit the rotation of the gear sector in this direction.

Screw threads Ill! formed in the shaft 84 are engaged by the threaded end of a plug I I I (Fig. 12) secured to the sleeve 99 by a threaded member I I2 and serves to form a threaded connection between the rotatable sleeve 90 and the non-rotatable shaft 34. Upon actuation of the operatmg arm I64, the drive is actuated to impart movement to the sleeve 99, causing it simultaneously to rotate through a predetermined number of revolutions and to move rearwardly on the shaft in a helical path. Upon release of the operating arm its, the torsion spr n I 6 a s, throu h the drive, to restore the sleeve to its normal position. A coil spring II l, interposed between the end of the bushing 9i and shoulder in the sleeve 90, serves to urge the sleeve longitudinally away from the bushing 52 and maintain the sleeve in its normal position, as indicated in Figs. 12 and 13.

At its forward end, the sleeve 98 is provided with a radially and longitudinally extending slot for receiving a winding finger I I8 therein for r0- tation with the sleeve 98 and for pivotal movement about a pin no carried by the sleeve. A head I 26, formed on the forward end of the winding finger I I8, is positioned. axially beyond the end of the stationary shaft 8d and extends radially inwardly toward the axis of the shaft as into close relation with a terminal positioned in the recess 38 of the stationary shaft. A transversely extending groove I 22 is formed in the head IZQ for receiving the bared end of the connectar wire I6 therein and for guiding the connector wire I about the terminal I5. A spring iZd, engaging the rearwardly extending portion of the winding finger I It, stresses the winding finger for rotation in a counter-clockwise direction about the pivot pin lit to urge the head I29 thereof into engagement with the terminal member I5.

In order to align the connector wire It with the groove I22 in the winding finger IE8 and to support it during rotation of the winding finger, a stationary support and guide member I25 is positioned at the forward end of the shaft 84 and the sleeve 9 The guide member I25 is formed on the forward end of the bracket I25 secured to a portion of the housing member 89, as illustrated in Figs. 8 and 9. The guide member I25 has an axially disposed central aperture to provide clearance for rotation and radial outward movement of the head of the winding finger I I8. In the upper wall of the member i25, a longitudinally extending slot IE8 is formed having an end wall engageable with the end of the connector wire It to locate the wir It in a predetermined position relative to the head I26 of the winding finger I It and to a terminal I5 positioned in the recess 85. In the lower right-hand portion of the guide I25, as viewed from the front (Fig. 11) a relatively wide recess I29 is formed to provide clearance for the reception of the free end of the i connector wire I5. When located in the end of the slot I28, as indicated in 10 and 11, the connector wire It is positioned adjacent the teriinal E 5 about which the connector wire is to be wound in alignment with the groove I22 in i the head I26 of the winding finger H8.

The other end of the winding finger IIB is inclined to form a cam surface I 32, which coopcrates with an annular conical cam surface I3 l formed on a sleeve 35 mounted for reciprocable movement on the sleeve 5i). A ring I secured to the inner portion of the barrel I35 forms a shoulder for receiving the thrust of a coiled sprin I33 which reacts against the shoulder I39 on the sleeve 99 and serves to urge the sleeve I35 rearwardiy to its normal position where it engages a portion of the housing 38, as shown in Fig. 13. A lever use, pivoted at its upper end I 32 to the sleeve E35 and fulcrumed intermediate its ends at I53 to the bracket 5%, has a finger piece I4 3; by means of which the lever may be actuated to impart forward axial movement to the sleeve I35 and cause the rocking of the winding finger H8 to a position permitting the application or insertion of the connector wire H6.

. nal in the recess 88 of the non-rotatable shaft 84 as illustrated in Figs. 12 and 13. With the index finger, the operator may then rock the actuat-' ing lever I68 to advance the sleeve I35 and rock the winding finger H8 to its open or inoperative position, with the head I20 thereof spaced from the terminal I5, after which the hatred end of the connector wire I6 may be placed in front of the guide I20, aligned with the slot I28 therein and moved axially into engagement with the end thereof, after which the actuatin lever I40 may be released to permit the retraction of the sleeve I35 and the movement of the winding finger I I8 to its normal position. As the head I23 of the winding finger I I8 moves radially inwardly, it engages the connector wire IS in the groove I22 thereof and urges it into firm engagement with the terminal I5. The upper portion of the conhector Wire I6 may be bent transversely and manually held in a fixed position on the supporting guide member I25, as indicated in Figs. 10 and 11. The operator may then engage and actuate the lever Illi which through the gear drive imparts rotation to the sleeve 953 through approximately three and one-half revolutions and simultaneously therewith causes an axial movement rearwardly of the sleeve relative to the stationary shaft and the terminal I5. During this rotary and axial movement of the sleeve, the winding finger IIS moving therewith serves to wrap the iree end of the connector wire I6 spirally and tightly about the terminal I5 and with the convolutions thereof in spaced relation to each other as indicated in Fig. 14. Since the downwardly extending free end of the connector wire It, a portion of which is shown in Fig. 11, is longer than the radius of the central axial aperture through the guide member I26, the connector wire it is bent into a loop by the head I253 of the winding finger H8 as the winding finger II8 rotates to wind the Wire IE about the terminal I5, and the free end of the loop gets progressively shorter as the wire I5 passes through the groove I22 as it is progressively wound onto the terminal. On completion of the winding operation, the winding device may be withdrawn axially from the terminal IE and the connection formed thereon by the connector wire I6.

It is to be understood that the above-described arrangements are simply illustrative of the application of the principles of the invention. Numerous other arrangements may be readily devised by those skilled in the art which will embody the principles of the invention and fallwithin the spirit and scope thereof.
