Description

W. MF'PLIE TOOL FOR FORMING INSULATORS Filed Ami]. 4. 1921 ill till
lipplicatlon flied .ttpril it, W21.
To all whom it may concern:
Be it lrnown that it, Vrironn'r Gr. llrrrn, a citizen of the lllnited ldtates, residing at Dayton, in the county oi" Montgomery and State of @hio, have invented certain new and useful improvements in Tools for Forming insulators, oil which the following is a specification.
The invention relates ing insulators.
One oi the objects of the invention is to provide a tool for forming insulators oi insulating sheet material and ior inserting them in armature core perforations or slots.
Uther, further and more particular objects oi the invention will become readily apparent, to persons slrilled in the art, from a consideration oi the iollowing description when taken in conjunction with the drawings, wherein ltig. l is an isometric perspective view oi the tool and a sheet ct insulating material inserted therein.
Fig. 2 is a similar view showing the in sulator termed on the tool. Fig" 3 is a sectional view of the tool.
lhig. d is a fragment of an end cit an armature core showing two of the insulators in slots.
in all the views the same reilerence characters are employed to indicate similar parts.
The insulator is intended for use in in sulating lbar wound armatures in which two bar conductors are to be contained within each slot or periloration oi the core.
The tool not only terms the insulators hut also serves as a convenient means tor inserting the insulators within the slots while the termed sheet is still on the tool.
The tool consists preferably oil a single piece oi steel having a shank 5 and handle it. There is a shoulder l at the junction oi the handle and shit toserve a useful purpose. The shunt: has a slot extend mg its lull length into which to insert one to tools tor iorrm the armature core.
herial lilo. llidfiltlll.
edge ot a sheet oi insulating material 9 as at 10, in l ig. 1. The depth of the slot 8 should equal the width of the opening in The tool is now rotated with the right hand while the left hand of the operator presses the sheet 8 into contact with the shank oi the tool.
The end view of the insulator then formed is indicated in Fig. 4 showing two separated openings 11 and 12, one for each loar conductor that are to occupy the respective slots or perforations in the core of the armature.
After the insulator has been formed in the manner described, and While yet on the tool, it is inserted in the opening in the armature core.
The shoulder 'i' prevents the insulator from moving axially on the tool while it is being inserted in the core.
After the insulator has heen placed in the core the tool is withdrawn and another insulator is tormed and inserted in like manner.
The insulator as an article of manufacture is disclosed and claimed in my Patent No, 1,284,552, dated November 12, 1918.
Having described my invention what ll claim as new and desire to secure hy Letters Patent, is 2-- l. A tool for forming and inserting armature insulators made of sheet material, comprising a shank and a handle with a shoulder at the junction oi the members, said shank being transversely slotted to receive the edge ot the sheet.
2.. ll tool for forming and inserting armature insulators made of sheet material, com prising a shank slotted longitudinally and at an angle to its transverse diameter to receive one edge of the sheet and a shoulder near the inner end of the slot,
in testimony whereof ll hereunto suhscrihed my name,
