Specification of Letters Patent.

Application filed July 3, 1905. Serial No. 268,263.
To all whom it may concern: l
Be it known that I. Crmunns Ln G. Fon'rrsoon, a subjectof the King of Great Britain, and a resident of \Yilkinsburg, in g the county of Allegheny and State of Penn- 1 syli'ania, have invented a new and useful, Improvement in Coil-\Vinding Machines, of
My invention relates to means for formi ing and insulating coils for electrical apparatus and itlias special reference to means that are adapted for properly insulating strap conductors and forming them into transformer coils simultaneously.
The object of my invention is to provide means forautomatically and simultaneously insulating a conductor and guiding it into position on a winding form that shall be simple and durable in construction and effective in'op'eration.
'lransforiner coils are usually composed of strap conductors and, in the prio art. such coils were ordinarily either insulated by wrapping a relativclyshort section of the conductor with tape orother insulating material and then winding the insulated portion'onto the former, or previously insulated conductors were utilized, in which case an insulating strip was usually fed onto the former with the conductor, which formed an extra insulation between the turns of the coil. The manual process is necessarily slow and laborious and may be materially facilitated and cheapehed by the use of my invention, which automatically covers the conductor with insulating material, as it is fed onto the former, and makes the process continuous.
A further advantage lies in the. fact that' the operating parts of a machine embodying my invention lend themselves readily to multiple assembling on a. single machine, so that several coils may be wound either in a vertical or a-horizontal plane at the same time.
My invention is illustrated in the accompanying drawings, in which- Figures 1 and 2 are, respectively, an end and a side elevation of a machine constructed in accordance therewith and arranged formultiple 'coil windin in a vertical'plane, a portion of the guide p ate being broken away, in Fig. 1, to disclose a'coil in rocess offor;
tional view of a tucker or wrapper used in connection with the machine of Figs; 1 and 2 for folding the insulating strip around the conductor as it is fed onto the former or mold.
Referring to the drawings, a plurality of guide-plates l and coil-centering blocks 2 are rotatably mounted upon'a horizontal 1 shaft 3, which is journaled in a stationary base i and maybe driven by any suitable means. A plurality of guide-arms 5 are rotatably mounted upon a shaft 6, which is also supported from the base 4, and each' comprises a straight body portion that sup ports a tucker or folder 7, and a curved end portion that engages the insulated conductor as it is fed onto the coil.
Referring particularly to Figs. 3 and 4, the tucker or folder 7 comprises a tube one side of which is open for some'distance at one end and is curved downwardly at the end to form a tongue 8 over which an insulating strip Q may be fed. A strap conductor i0 is fed into the tube 7 on top of the insulating strip 9, which is made of sufficient width to completely .infold the conductor. The 'constructionfof the folder 7 is such that the insulating strip is automatically wrapped aboutthe,conductor 10 as they pass through, so that; the conductor comes from the opposite end of the tube completely wrapped in insulating material and may be wound directly onto the winding form or coil-centering block 2. A tucker or folder tube may be conveniently constructed to accomplish these results by foldmg over the edges of a strip of sheet metal so that an insulating strip of the desired I flanged side overlapping the other, through which the conductor may be fed after be ing insulated. At the other end of the metal. strip, where it is relatively fiat, the edges :are not turned over and the end is curved to form-the guide tongue- 8 for the insulating strip. A considerable length of metal strip is utilized in the evolution from the flat portion to the elliptical tube, so that the in; sulating strip may be gradually bent and by avoiding injury to the insulation and folded around the conducting strap, thereallowing the conductor to be fed to the ma chine more rapidly. As the insulated strap leaves the folder 7, it is forced against the edge of its supporting guidearm by a spreader 10 which serves to prevent the abrasion of the insulation by the guideplates and also serves to more closely press the insulating strip against the conductor.
Although I have shown and described a specific arrangement as a means to an end, I desire that structural variations which do not materially change the mode of operation or result shall be included within the scope of my invention.
I claim as my invention:
A folder for applying an insulating strip to a strap conductor, said folder comprising a downwardly projecting curved outer end provided with upright guide flanges at its edges. an intermediate, partially closed tubular portion and an elliptical tubular inner end.
In testimony whereof, I have hereunto subscribed my name this 28th day of June, 1905,
CHARLES LE G. FORTESOUE.
