To all whom it may concern.-
Beit known-that ALDRED K. WARREN, a citizen of the United States, and a resident of New Brighton, county of Richmond, and Statel .of New York, .n have invented certain new and useful Improvements in Commutator- Brushes, of which the following is a specifirlhis invention relates to commutatorbruslies for dynamos, electric motors, doc.,
the main object of the invention being to provide a brush adapted: to utilize the whole length of the contact material or body of the brush, such as wire, woven Wire, metal strips, or carbon, thereby avoiding waste which occurs in connection with brushes now in .common use, owing to the fact that when the brush is but partially worn away it becomes In the improved brush the outer end of the contact part when of wire, carbon material is-mad an extension-piece and securingdevice whereby almost the entire length of the contactbrush can be used.
In the d rawingmlligure l is a bottom plan viewof myimprovedv brush complete. Fig. 2
is a )similar view ofthe woven-Wire or other contact part of the brushdetached from the end extension. Fig. 3 shows the end extension detached. Figs. 4 and-5 are respectively ed gel Views 'of the partsshown in Figs. 2 and Fig. 6 is anend View of the part shown in Fig. 4:, looking from the right. Fig.
7 is an endview of the part shown in Fig. 5, looking .from the left; andFg. 8 is a connecting bolt or screw.
A is a commntator-brush body, B being the l end that in use bears on the commutatorcylinder or surface, and C beingv the outer reduced end, which is vadapted to be connected to an extension-piece F, which is preferanly of aluminium, but which may be of other metal or suitable material. It is bestto have piece F ot' the same width and thickness as the part A, so that when together their sides and edges shall lie in ycommon planes. The part F is preferably formed with two projecting arms G, grooved on the inner sides and similar yielding or fragile o l'id'and formed to receive Vhen'part A is subdivided or is of yielding or of fragile material, the end C of the brush for a considerable distance, say an inch or inch and a half, is solidifiedin a suitablemanner, as by dippingsaid end into molten metal in such manner that it Shall permeate the. interstices o'f said end, making itziirm and strong, as well as binding Athe separate layers or subdivisions together, similarly to soldering the ends-together, as has been proposed. The more lightly-shaded part `D. of
brush A indicates'the portion made solid, 4as l described. The hole E, the'wholezgof'the refduced end, and the'. shoulders `J are inthe solid portion. When partA isrstused, it may be without F, and when it becomes worn so as to be too short for vconvenient use by itself the extension F can be secured thereto and the contact part A utilized to the solid end D.' Parts A and F being of the saine or similar cross-section can each be held by' the same brushliolder. Only one bolt I is necessary in the construction shown, since the grooves in arms G prevent parts A and F-.turning independently of each other. Other means than that shown may be used to hold parts A and F in line with each other.
I claim l.. The combination ota cominutator-bL .ish of material adapted to rub on a commutator, an extension-piece of similar cross-section to the brush, and means for fastening the brush extension together. i 2. The combination of a commutator-brush of yielding or fragile "material, the outer end thereof being reinforced, an extension-piece fitted thereto, and means securing'the brush, and extension together. 3..- .The combination of a commutator-bljush of yielding or 'fragile material, the outerlend;
being made soiid or reinforced, said end behaving arms G, the iuzlc' sides of which are ing 'cduced and perforated transversely, au groove@ 0o it end C, and boit passing Io extension tted to the reduced end, and a thohgh amas@ and end C. n
ooit or pi passing through said eric-ration Signed this 5th day of Mey, lSQO.
