APPARAIU FOR AND METHOD OF WI'IIPPING .STEANID ABC UT 1ft CORE.
Application filed August 29, 1924. Serial No. 734,883.
T 0 all whom it may concern.
Be it known that I, HALTER Sawnn' ihxmi, a citizen of the United States, residing at Berwyn, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in an Apparatus for and Methods of \Vhipping Strand About a Core, of which the following is 'a full, clear, concise, and exact description. I
This invention relates to an apparatus for and a method of whipping strand about a core, and more particularly to a method of and a mechanism for whipping telephone cords with strand material preparatory to securing terminals thereto.
An object of the invention is to whip cores with strand material accurately, speedily, and with a minimum amount of manual labor.
In accordance with the general features of the invention there is provided means for withdrawing a predetermined length of wire from a supply spool and winding it on a bobbin which spirally whips it about the end of a cord, positioned in the center thereof, the cord being moved along its aXisthe required distance for each turn of the wire wrapped or whipped on the cord.
Other objects and advantages .of the invention will morefully appear from the following detailed description taken in connection with the accompanying drawings which illustrate "a mechanism embodyingthe invention and'in which drawings,
Fig. l is a side elevation of the whipping mechanism;
Fig. 2 is a planview thereof;
Fig. 3 is a front view of the mechanism. a portion of which is fragmentarily shown in section;
Fig. 4 is an elevation, partially in section, taken from the side, opposite to that shown in Fig. 1 and showing a portion of the whipping mechanism;
Fig. 5 is a detail view of the bobbin which whips the. wire about the cord;
Fig. (5 is a detail view ofa' resilient guiding and catching device thereof;
Fig. 7 is a detail view of the stationary member showing the hook for guiding the wire; V
Fig. 8 is a view of the cord after it has been removed. from the whipping mechanisms d 3,
Fig. 9 is a diagrammatic View the way the wire is laid on the end of the cord.
It is believed that the method of whipping Located to one side of the supply spool 12 is a pulley 16, keyed to a shaft 17, and driven by a belt 18 connected to any suitable driving means (not shown). Also splined to the shaft 17 is a pulley 19, which through a belt 20 drives a pulley 24 keyed to a shaft 25 (Fig. 4). Contiguous with the pulley 24 and likewise keyed t0 the shaft- 25 is a cam 26, the cam surface of which is adapted to actuate a pin 2'? pivot-ally secured at a point 28 to a bell crank lever 29 (Fig. 4), pivoted at a point 30 to the frame 10. One arm of the lever 29 is bent upwardly in such a manner that its end 33 rides on top of a cord support 34(Figs. 1 and 2).
The cord support 34 is reciprocably mounted in the keyway 35 (Figs. 2 and Formed on the cord support 34'is a member 36, the end of one arm 37, of which rides in a cam like surface 39 of a cam 40. Integral with'the arm 37 is a pin 31, the end of which passes through a hole 32 in the frame 10. lnterposed between the member 36 and the frame 10 and surrounding the pin 31 is a compression spring 41. The cam 40 is keyed to a shaft 43 rotatably mounted in and carried by a bracket 44 secured to the frame 10. Splined to the other end of the shaft 43 is a gear 45 which meshes with the gear 46 keyed to the shaft 17. Also keyed to the shaft 17 is a gear 47 which meshes with another gear 48 which is integral with a rotatable circular member 49, both the gear 48 and the member 49 rotating about a stationary circular member 50 (Fig. Mounted on the rotatable member 49 is a resilient guiding, wire catching and retainon the pin are two washers T3 and Tl. Surrounding the "win 55 and interposed between the washer T3 and the washer T1 is a spring 57 secured at one end to the washer T 1- and at the other to the washer 73, which (llzlWs the member 5% inwardly against the surface of the rotatable member le f te-cured to the revolvable member it) is a pin 11% which tits in a hole 59 in the member 5' and serves to prevent the round member 5 from revolving. Likewise, f tened to the member -19 another pin (31 shgitly beveled at its end 9- which tits in a hole (53 in the member 51 and serves to prevent the wire 13 from leaving the device 5-13.
Also attached to the rotatable mem er if) is a small arm 60. the end of which is formed into a U-shapcd guide (il. l nding through the stationary member i is a hole ('35 in which is secured a U-shaped guide (so formed similarly to the U-shaped guide (l7; both of the guides being located at the center of the members -19 and 50 and the gear 48 6). Secured to the bottom of the forward part of the guide (36 i. a hook as shown in Fig. 7, which s rves to p operly guide the wire 13.
Integral with and surrtainding th her 4:9 is a cap shaped element (5? 1 which forms a bobbin denoter generally by reference nmneral C 1 and is providet with a slot (38. Positioned to the 121l ot the 8 and integral with the element (3? is a v. ing shaped member 69. Located between the member :9 and the cap 6? is an annular space 70 (Fig. in which the predetermined length of wire is wound as will be more fully described hereina'tter. It will be noted that the cord support 2-3-1 is provided with a V-shaped groove 72 which is in alignment with the guides (31 and (3G.
The operation of this mechanism is as follows: The ope 'ator withdraws the wire 13 from the spool 12 and threads it through the hole in the stationary member 50; the wire 13 passing through the center of the U-shaped guide (36. through the book To and through the center ot the U-shapet guide (31-. The wire 13 is then drawn along the bottom of the groove 72 in the support 3&- (Figs. 1 and 2) and over the end 3 of the lever 29. It is to be understood that bet'ore the machine is set in operation the operator must pull the wire 1;} outwardly from the stationary member .70 until its end is in line with the end of the frame 1t); the distance between the member 50 and the end of the frame 10 being approximately equivalent: to the predetermined length of wire required for one whipping operation.
Upon the application of power to the belt 18, the cam 26 is caused to revolve through the pulleys 9d and 19 and the belt 24). The cam 26 actuates the pin 27 causing the lever 29 to pivot upon the point 30. The lever 29 in pivoting carrier the wire 1 1 just laid on the end fl?) ot the lever upwardly. a shown by the dotted line.- in Fig. -l-. until th wire 1?; is caught by the clicllfil' mem er fit of the resilient guiding and catchin thri 53 secured to member in wh at. this time rotating by means ot the revolving T upon coming gears and 1-7. 1 he wire 1 into contact with the member 5t tween the member 5-1 and the la e ol the member 15) and the beveled end (3:: ol' the pin t'd assuming a position to the rear of the pin (51. the pin til prevents the wire 13 from tiying out from under the men'ilier 5t and the pin serves prevent the member from being turned by the wire 1 The wire 13 then enga ed by the wing (it) on the rotating member to which causes it to enter the slot. (38 in the cap (37 (Fig. .3). and to be vound in the space TO about the stationary member 50. The cam is of such a design that as soon as the wi e wound in the space i it permits the leve 9. throuu'h gravity, to fall bacl: into its or nal position on the support ll. A. cold is: then laid in and held in the groove T1. ot the support ill and on top (it the end 1 ot' the lever 2t and with its end. to be whipped. lying in the guides tit and (H3. whieh support the fOltl centrally ot the months. 111K150 and on top ot the wire i i. The member -14) in revolving about the stati narv member 50 and the cord In whips the wire about the end of the cord. The wire 13 used for the whipping is withdrawn from the space ot' the bobbin T1 and guided by the device 53. The wire 1 3 in being S ides trwhipped about the end of the cord is prevented nn pulling the cord t'rom its eert'al position in the guide (3t; bv the guide (it which revolves around with the mem ber 49.
The cam 10 through the gears, an is caused to revolve and its sin-lace t? is designed that as soon as the whipping ot' the wire 13 about the cord T5 starts. the pin 37 is actuated which through the member l i moves the cord support :i-l outwardlv causing the wire 12") to be whipped spirallv around the end of the cord. The cord sup-- poit l-- in being moved outwardlv compresses the spring 11: and the end 3 ot lever 29 rides along the top of support 31; under the cord i I 'hen all of the wire has been withdrawn from the bobbin Tl and whipped about the end of the cord spirally. the o ierator pulls the cord outwardly. drawing the wire from the spool 12 with it until the whipped end of the cord is clear oi the end ol. the support 31 at. which time the wire is cut. 'lhe cam 40 of such a design that it will cause the support 31- to he moved mtwar lly a distance just sutiicient to permit the whipping ot the end of the cord with the prcdeter lifi mined length of wire, the removal of the cord from the support 34 and the severing of the wire, whereupon spring 41 is allowed to expand forcing the support to be re turned to its original position.
The lever 29 is then set in motion by cam 26 causing the wire drawn outwardly by the support 3% and by the operator, which is the predetermined length of wire to be wound on the bobbin 71 as has already been described and the whipping operation is repeated.
