Specification of Letters Patent.
s tellites Jan. a 912 fipplication filed July 10, 1907. Serial No. 383,050.
To all wl'wm may concern: V
Be it lmown that I, MATHIAS PrA'rIsoHER, a citizen of the United States, residing at Eavcnne, county of Hudson, State of New soy, have invented certain new and use-- QVEEUQZliES in Commutators;' and I reby declare the following to be a full, clear, and exact description of the inventi 2:, 51161 as Will. enable others skilled in the to which appertains to make and use the i The object of the invention is to improve mechanical construction and reduce the of commutators for dynamoelectric cry, the improvements relate cularly to the construction or? the cornnutator bars, which are made up of a con made of metal having a high supporting structure terial which is cheaper than ;.:cc and Whicl preferably is resisting mechanical itererring to the drawings which illustral c red ccnstructions Figure l is a c Nikon of a commutator made up or commutator bars constructed in accordance with my invention; Fig. 2 is a cross i ig. 3 is a central for simplic r a modified our} H g. e is a ectiozi of the same, and i i-g. 5. is
section of single commutator bar of is made igs. l the Cfllfiilllltalr r outer cijsnfi mg con-- which tile c rent colins; hrs and which is preferably 46 ide copper and of suiiicient depth to serve the p rposes of conduction and to allw tor reasonable amount of Wear and sing. conducting st p is Welded A per a i 2 plei" of steel, in s shaped gagged by the clamps l on the shaft of the commutator. It understood that these commutator place-d in position separated by insnlaticn and clamped in any 3* own to the art; and that their of support and clamping and insuorn'is no of the present invention in the construction illustrated in Fi s. 3
section of the same, the parts being broken s U Hill section or commutator liar- 4: and 5, the same contact conducting strip 1 is used, but in place of the strain resisting supporting strip 2 made in a solid piece, I have substituted a supporting structure made up of two pieces of metal 5 and 6 suflici'ently thin to be stamped, and separated by a spacing piece 7 the pieces 5 '6 being WQldQd to the conducting stripes before. This construction is snl'iiciently rigid for all purposes and besides being light is extremely cheap, since the pieces 5 and 6 may be stamped in appropriate shapes and the necessity'for machine tooling is done away with.
What I claim is 1. A composite commutator bar for dynamo-electric -machines made up of an outer contact sect-ion of a material having good.
conductivity, joined at its base to a plurality of thin metallic plates forming an oer supporting structure, substantially as clescribed.
2. A compositeconnnutator bar for dy name-electric machines made up of an outer contact section of a material having good conductivity, joined at its base to a plurality of thin metal plates forming an inner supportingstructurc and shaped for locking engagement with the commutstor clamps, substantially as described. I
3. A composite commutator bar for dynamo-electric machines made up of a contact section of copper supported by two thin metallic plates spaced apart and shaped "for lockin en 'a-enient Witb' tlie commutator J b clamps and elded to the copper, substsutislly as desori i. A composite commutator bar made i of the copper contact section 1, the supporting plates, it and 6, Welded thereto, and the spacing piece Y, substantially as described.
5. A composite commutator bar for dynamoelectric machines made up of an outer contact section of a material having good conductivity, oined at its base to a plurality of stamped metal plates forming an supporting structure substantially as described.
