To NATIONAL BRAKE & ELECTRIC COMPANY, OF MILWAUKEE, WISCONSIN, A coRPORATION of WISCONSIN. DYNAMO-ELECTRIC MACHINE. No. 893,681. specification of Letters Patent... Patented July 21, 1908. Application filed December 13, 1908, serial No. 347,611. To all whom it may concern: - - - axis, then along vertical plane. 11 between it known that , WILLIAML WATERs, horizontal pole 4 and bearing parts 10, citizen of the United States, residing at Mil. then horizontal plane 12 which is below the waukee, in the county of Milwaukee and pole 4. With this construction there is noth State of Wisconsin, have invented a certain ing in the path between the opposite edges in 60 new and useful Improvement in Dynamo the various planes, and each path of the casing Electric Machines, of which the following is a can be laid on a machine bed and milling or full, clear, concise and exact description, ref planing tools can be carried SE aCOSS erence being had to the accompanying draw to practically cut and finish the edges in one ings, forming a part of this specification. operation, and the finishing of the edges, 65 EEE relates to dynamo electric therefore, becomes a-very simple matter, the machines, having for its object improved g being also true, thus insuring a tight features of construction and arrangement, and perfect fit when the halves are brought particularly of the field magnet and inclosing together. It will be noticed that the halves 5 of the bearings are also finished during the 70 My invention is of particular importance same operation. With this separation of and utility in inclosing motors or dynamos in the parts, the upper vertical and right hori which it is necessary to have a perfect ma Zontal pole i the EPE bearing halves chine fit between the top half and the lower may be cast integral wit the upper section, . 20 half of the frame which incloses the armature and the lower vertical and left horizontal 75 and which supports the field poles. To ob poles and the lower bearing section may be tain this perfect fit, the edges of the castings cast integral with the lower or base section. must be machined, but this in machines of This Ege is very useful in that when the prior art is very difficult to perform, ow the top half is removed, as shown in Fig. 2, 25 ing to the fact that the field poles and the the armature shaft with the armature can bearings interfere with finishing the machine. 80 I, therefore, have the line of separation be bearings.. readily be inspected or lifted from the tween the upper and lower halves of the cast I do not wish to limit my invention to the ing in such position that the poles and bear particular form of machine here shown, as it 30 ings will be cleared and straight uninter may be applied to machines of other con 85 rupted paths offered for the finishing tools, struction. and the arrangement of my invention will be I claim as new and desire to secure by Let best understood by reference to the accom ters Patent: . . panying drawings in which 1.
