. is a specification.
My invention relates to improvements in electro-dynamo machmes, and it consists 1n the combinatlons. constructions, and ar- 1 rangements herein described and claimed.
IAn object of my invention is to provide an economical means for constructing elect-ro-dynamic machinery, such as direct and alternating current generators or motors, these devices being constructed largely of rolled, or die pressed sheet metal, the sheets being punched or presed and the parts generally being provided with strengthening flanges.
A further object of my invention is to provide a device of the type described in. which the parts which are usually made of heavy solid metal, such as the forms for holding magnetic core of the armature,the saddlesor base portions for supporting the machines, the boxes or bearings, the commutator bar support, the hangers for holding the boxes or hearings in position, the pal-- leys, the brush holders, are made almost entirely of pressed and flanged sheet steel, certain of the parts, however, such as the armature core support the boxes, etc., being arranged to hold the heavier metals such as cores and bearing linings.
A further object of my invention is to provide a construction of the type described by means of which the various parts maybe more easily assembled or taken apart.
A further object of my invention is to provide devices of the t described which are relatively light in weight in comparison with their efliciency.
Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawings forming part of this application, in wh1ch Figure 1 is a central sectional view through a machine showing one embodiment of my invention.
Fig. 2 is a section at right angles to Fig. 1.
Fig. 3 is an end view of the device.
Fig. 4 is a side view of one of the bearing supports and its hanger.
F Fig. 5 is a section along the line 5-5 of Fig. 6 is a perspective view showing one form of the base or saddle.
Fig. 7 is a perspective of the base plate.
Fig. 8 is a perspective view of the brush rocking device.
Fig. 9 is a perspective view for the armature core.

Fig. 12 is a sectional view showing a manner of supporting the machine.
F Fig. 13 is a section on the line 13-13 of Fig. 14 is a perspective view of a modified form 'of saddle.
Referring now to Figs. 1 and 7, I have shown therein a base plate 1 which is provided with bolt openings 2 bordered by flanges 3. Supported upon the base plate is a saddle 4 like that shown in Fig. 6, this saddle being held to the base plate by means of bolts The saddle l is provided with stamped guide sockets 4 arranged to receive the flanges 3 of the base plate. At 4 the saddle is cut away to permit access to the bolts 7. Carried by the saddle is a ring 6 of conducting material such as iron or steel. this ring being secured to the saddle of a support by means of bolts 7 which also secure the on both sides as shown in Fig. 5. The boxes 10 are made of presed metal each half having any form or any number of offsets. desired which can also be used in the construction of pulleys and shaft hangers for all purposes, there being a portion on each side of the hanger 9 secured by welding. screws or rivets, these portions inclosing bearing pieces 11, which are held in position by means of screws 12. The lower rtion of the boxing is formed into an oil c amber 13 into which an oil ring 1i dips. As will be seen from Fig. 1, I may provide a strengthening member'15 which is secured to the hangers 9, thus adding strength and stability to the bearing supports.
Disposed centrally of the device and ex- Fig. in which two sections I or pressed out and joined together, or one Section alone wil entirely suficient tion to force a smaller cross section against the to crowd the insulation into the dove-tailed,

I ma he in two pieceslikethat shownin Fig. 14 at Fig. 1, to this sleeve fits into thereduced lportion 21- of flanges arranged to crowd ins ating tending through the bearings is a shaft 16. This shaft is whose construction may be that shown in are stamped l form a pulley whichis for some purposes.- Disposed on the shaft 16 is a sleeve 18 which is-provided with a pressed keyway 19 into which a key 20 may be inserted, see key it to the shaft 16. One end of a commutator support 22. helatter is threaded externally at one end to receive a flanged U-shaped ring 23 havin dove-tail material 24 into the dove-tailed recesses of the commutator bar 25 or parts 21 and 2 2 may be combined in one piece. At the opposite end of the commutator support 22 it is threaded internally to receive a. ring 26 which is substantially Z-shaped in crosssec= ring 27. of shaped recess at this end of the commutator bar, thus holding the bars securelyin position.

In Fig. 14 I have shown a modified form of the-saddle portion of the base.' In this form making the saddlein one piece as 51, or the two pieces could bemade in one as at Fig. 6. In-each instance, however, the

F1 8 I have shown a portion of a brush holder yoke or rocking device consist- .ing of a body portion 30 having a single sleeve 31 pressed therefrom, said sleeve being provided with'slots 32. The body portion is provided with arms 33 for supporting rods 3l, see Fig. 1, which bear the brush holders proper. The sleeve- 31 of the yoke is rotatably mounted on one of the bearings 10 and may be adjusted thereon by unscrewin and then tightening the set screws 35 whic extend through the slots 32 in the bearing.
