R. W. BAKER ARMATURE INSULATION CUTTIN MACHINE Original Filed March 15, 1926 2 Sheets-Sheet 1 Dec. 4, 1928.
R. w. BAKER ARMATURE INSULATION CUTTING MACHINE Original Filed March 15, 1926 2 Sheets-Sheet 2 into alignment with a plunger 48 whichis operated by the head of a unch press not shown.
' It will be understood t iat the horizontal bed I of the punch press supports the plate 42. In
this position of the base 41,the central aperture 31 in the block 30 will be located vertically above an aperture 49in the plate 42.
The punch press is then operated to cause the plunger 48 to descend in order to force the core 20 downwardly through the openings 31 and 49. During this down ward movement ofthe core 20, the wheels 26 will engage the armature insulation strip 22 as indicated .in Fig. 2 in order to cut the strip at theedges 23 i oi the armature core teeth.
j The plunger 48 is provided with a spherical recess 50 for receiving the overlapping portions 23" of the armature windings, and with a c lindrical recess 51 for receiving one end oft 1e arn'lature shaft 21. The plunger 48 is rovided with grooves 52 which receive t e cutting rollers 26 during a portion of the downward movement of the plun er 48. These grooves 52 divide the lower edge portion of the plunger 48 into segments 53.
These segments 53 are the only portions of the plunger 48 which engage the armature core 2 0 in order to move it downwardly as viewed in Figs. 3 and 6. V The windings are not injured by the apparatus since pressure is not applied to them; and the shaft 21 is not shifted relative to the core 20 by the operation of the apparatus since the plunger 48 does not apply pressure to the shaft 21.,
The punch press will-return the plunger 48 to the upper position shown in Fig. 6 so that it will clear the upper end of the shaft 21. Then the handle 47 may be grasped by the operator in order to move the block 30 toward the right so that the work may be inserted into the apparatus. The armature and thesuperfluous portions of insulation 25 which have been removed are received by a suitable hopper located below the opening 49 in the late 42. p
It will noted also that the rollers 26 will compact the windings 23 and will cause ortions 22 of the slot lining insulation to pressed against the windings as shown in Fi 2. j v ft is apparent that the present invention provides forrapidly iemoving the superfluous portions of insulating material from the armature core. This work can be done as rapidly as the operator can insert the work in the fixture andoperate the punch press. As considerable time has been saved, the cost of this portion of the manufacture of an armature is materially reduced.
While the form of embodiment of the pres ent invention as herein disclosed, constitutes a referred form, it is to be understood that ot ier forms might be adopted, all coming supported by the bed of a punch press, and
the moving means is a plunger adapted to be attached to the head of a punch press and is provided with recesses for receiving the armature shaft and windings and with surfaces which bearonly against one end of the armature core.
3. The machine as defined by claim 1, in 'WhlCl]. the.cutting means comprises a plurality of cutting wheels supported by the guide in radial alignment respectively with the slots in the core. 7 y
4. An armature core insulation cutting ma chine comprising, in combination, means for guiding the core, means for moving the core endwise through the guide and means entering the core slots and cooperating with the core teeth simultaneously to cut the insulationhat adjacent edges of side by side core teet 5. An armature core insulation cutting machine comprising, in combination, means for holding a slotted core member having sheet insulation adjacent its teeth and lining its slots, 21 member, adapted to enter a core slot and to cooperate simultaneously with adjacent peripheral edges of adjacent core teeth to sever the insulation, and means for producing movement of the core member relative to the severing member. Y
6. An armature core insulation cutting machine comprising, in combination, means for holding a slotted core member having sheet insulation engaging its teeth and lining its slots, a plurality of cutting wheels each adapted to enter a core slot and to cooperate simultaneously with adjacent peri heral edges of adjacent core teeth to sever t e insulation, a member for supporting said cutting wheels in radial alignment respectively with the slots ofthe core member, and means for producing movement of one of said members relative to the other. 7
7. The machine as defined in claim 6 in which each cutting wheel is so shaped as to engage the severed edges of the core slot lining insulation and to push the same into the core slot. i
In testimony whereof I hereto alfix my signature.
RUSSELL 1W. BAKER.
