.ART OF ARMATURE CONSTRUCTION.
Toalla/hom z't 'may concern:
Se it known that I, VINCENT G. APPLE, a citizenpf the United States, residing at Dayton, 1n the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in the Art of Armature Construction, of which the following is a specification.
My-invention relates to the art of armature construction and has especial reference to a method of welding armature conduc- 4 to a commutator segment.
tors together in pairs and simultaneously One of the objects vof my invention is to rovlde a new and improved method of joiningfthe terminal ends of armature conductors together and simultaneously to appropriate commutator segments or bars.
Other andv .further objects of my invention will become readilyv apparent from a consideration of the following; description when taken in conjunction with the drawf ings, wherein and commutator showing the manner of connecting the armature terminals to the commutator bars.
rig.y 2 is an enlarged section taken on line 2-2 of Fig. l.
Fig.Y 3 shows a fragment of the completed work. l
Fig.` 4 isa conductor bar connector.
' l In all the views the same reference characters indicate similar parts.
In the example illustrated the armatureconducting bars '5V and 6 constitute a pair adapted for connection together and to a comment and serves as a filler.
therefore provide a connector 8 (see Fig. 4) having a cross section in outline resembling the letter H. This connector is preferably made of copper and is slipped in between Figure 1 1s an end view of an armature Specication of Letters Patent. Patented Allg. 27, 191.8. Application filed February 1:1, 1.918. Serial No. 217,152.
. isl slipped. over the rear end of the commutator and vthe screw 16 is turned down on to a block l17.y A conducting stripv 18, havlng, preferably, the shape of the conductor connector 8,v but preferably of substantially non-weldable metal,- at `the relatively low temperature at 'which copper softens, is placed over the top edge of the terminal 5 and the screw tightened. The lower edge of the terminal 6 having been placed fin a groove cut into the rear end of the commutator bar 7.
The 4conducting strip 18 is connected to a source of current supply, not shown, by the wire 19.
Another" ring 20 having an insulating lining 21, is placed over the front end of the commutator and the screw 22 is tightened connected. The'wire 23 is connected to the source of current supply and thecircuit closed. So soon as the terminals 5', 6 and the connector 8 begin to soften, pressure is applied to complete thev weld'. This may be done by turning the screw 16.
Other welding apparatus, difering from that shown, may be used. That shown is of the simplest conventional form.
After one set of joints have thus been made, the next adjacent members are likewise welded together land so on, until each pair of terminals has been welded to its commutator bar until all have beenjproperly joined.
Having described my invention, what I claim is 1. The art of joining radially disposed pairs of spaced-apart armature terminals to commutator segments, which consists in placing an alining filler block between the terminals; placing one edge ofone of the pair of terminals in contact with a commutator bar; passing a current of electricity through the commutator bar, the terminals and the block, and applying pressure as the metal softens,`.to weld the four elements together.
2. The art of joining relatively wide and thin, radially disposed, spaced-apart arma'- ture terminals to commut-ator segments which consists in' preparing a filler guideblock which will hold the terminals in a common radial plane; placing the block materially p terminals; placing one of said terminals in contact with a commutator bar; placing a substantially non-weldable electrically conducting block in Contact with the other terminal connecting'said. eommutator bar, said terminals and blocks in an'electric circuit; closing said circuit andy-.applying pressure `to the parts to be Welded.
3. The art of joining radially-disposed pairs of spaced-apart armature termina/ls after they are in place on a core of "the armature which consists in placing an alining filler block between the terminals; Weltling both terminals t0 the filler, then weldjng the terminals and ller to 4a commutator In testimony.whereof I hereunto set my VINCENT G. APPLE. l
