VARIABLE BECIPBOCATING TEAVERSE MECHANISH. Application tiled Aug-ult 22, 1921. Serial No. 494,410. (Gm m28. THE 2110171810118 F THE ACT 0F MARCH 3, 1921, 41 STAT. L., 1318.)
To all whom it may concern.'
Be it" known that I, STANLEY ROBERT Warum', a subject of the King of Great Britai and resident of Rawdon, near Leeds,n7Yorkshire, En land, have invented certain new and use u1 Improvements in and Connected with Variable Reci recatdriven unidirectionaly. e 1
ing Traverse Mechanism (for which have obtained a patent in Great Britain dated May 29, 1919, No. 149,104), of which the following is a specification.
This invention relatesto that type of reciprocating traverse mechanism vfor coil wlnding machines in which the wire or thread guide is reciprocated across the face of the spool by means of a continuous band One object of the invention is to provi mproved means in a mechanism o the above type for operatively connecting the wire or thread guide to such a band.
Another object is to .provide means for automatically varying the shape of the coil according to varying requirements.
Other objects and advantages will appear hereinafter.
In order that the invention may be clearly understood the same will now be described by aid of the accompanying drawings in which Fig.v 1 is a plan view of part of a coil windmg machine to which this invention is applied.
F1g. 2 is a side of the same. f
l Fig. 3 is an end view of Fig. 2.
Fig. 4 is a section of a magnetic pulley used in connection with the .inventionI in the present example of the same.
Fig. 5 is adiagram of the electrical connection of the apparatus.
According to the practical application of the invention shown in the drawings and as applied to a coil winding machine for repartly sectional elevation ciprocating the wire or cotton traverseA guide, the constant speed single direction motion is obtained from a motor not shown and is imparted to one. of the band carryin pulleys a through the medium of beve gears c, which', in the present application, re lace the usual cam.
o obviate slipping of the band under the net. The other end o the endless band 1s supported by an idler pulley b which is held 1n variable spaced relation withI the magnetic'pulley by tie-rods f which also serve as slides or guide bars for the magnet carryin member g.
This mem r, in the present example, carries a palr of ma ets l. andi connected in serles the poles y of which are in vertical ahgnment with each other, the outer faces y1 of such eachap reaching to within a small distance of t e inside faces of the top and bottom runs respectively of -the steel band d. In conjunction `with each magnet pole is a p-ivoted armature lo each of which is disposed with the respective run of the steel band interposed between such armature and its pole.. Upon alternate energization of the magnets the respective runs of the steel band are correspondin ly attracted thereto and augmentation of t 1s grip is obtained by th'e subsequent attraction of the respective armatures-with the result that the magnet carrying member is re1 ciprocated upon its guide bars.
Two links la* pivotall connected at their ends to opposite lugs 2 res ectively rojecting from the hinge mem rs to w 'ch the armatures k are rigidly attached, are provided for ensuring that the upper armature shall be lifted clear of the endless band d when the lower armature a is attracted to its corresponding' magnet.
Alternate energization of the magnets is e'ected by means of a pair of contacts Z lsee Figs. 1 and 3, which are mounted in adjustable connection with a fixed rod or rods m which are insulated for the purpose so as to reside one upon each side of the magnet carryingmember g. These adjustable contacts are caused to alternately be engaged by corresponding faces n on a contact secured to-in the present example-the wire guide o of the coil winding machine.
This wire guide is pivotally connected to the magnet carrying member as at p so as net is cl and forms a grippin two mets are pl to move therewith and in a plane at right ngles to the anis oi the coil to be wound.
n face of the lined contact and the corresponding adjustable contact rits in the short-circuiting of one of the magnets and full energzati'on of the other with the result that the armature of the energized magconnec tion with the corresponding run o the steel band and weer like movement of the maet rryin member.
1 @n traversing the full distance allowed by the other ad'ustable contact the process is repeated wit a consequent reverml of motion.
The electrical connections between the contacts and a g1 ets will be seen from Fig. 5 are such that whilst traversing thespace intermediate the two ad'ustable contacts the ,in series with one another. The resulting dur is suliicient to simultaneously operate the other whilst the current is out down to enable the coils to remain cool.
As indicated in dotted lines in the drawing, the pivot wire guide o rests ainst the periphery of the coil being Wound, therefore as the diameter oi the coil in-a creases, the pivoted wire guide is caused to corresmndingl turn about its pivot. This results in the acesl oitie fixed contac eina 'n pro ssive i erent points o `t e djgiistble gcbentact ysurfaces. This feature is utilized to automatically obtain varia.-
-tons in the shape of the wound coil, such shape being a replica of the shape deined by the opposing edges of the adjustable contacts, which eds also control the length of traverse o the mat carrying member and, as a consequence, the length of traverse et the wire guide. Thus in the embodiment illustrated, as the coil grows the wire guide will be turned about Vthe pivot p in a counter clockwise direction (according to Fig. 3) and lthe contacts n will engage with t e contacts Z for effecting reversal of the wire guide, after strokes of progressively diminishing am litude. The length of traverse will accor ingly diminish' with the result that a coil with beveled ends will be produced.`
Had the contacting surfaces of the contacts l been at right angles to the stroke of the wire dguide, it is obvious that a straight ende coil would have been produced.
What l claim and desire to secure by Letters-Patent is 1. A traverse mechanism tor coil winding machines, comprising a reciprocable guide for the material to be wound, electromagnetic means associated with said guide and movable therewith', an endless belt, of magnetic material adapted to be driven uni operation the engagement between one.
