To all whom it. may concern:

Be it known that l, PATRICK J. CoLLINs, w citizen of the United States, residing st Scranton, in the county of'Lsckswsnnaand State of Pennsylvsrmt, hove invented certain new snd'usei'cl Improvements in Electricbsgrs or partitions arranged between the; srlnstcresce each axle, these bars or .parti- "by partitions-which form parts of the netic circuits. tor-truck similar to that shown in Fig. 1, the

This invention relates to improvements in electric-railway motors of the SllOWIl in rn'ycopending application, Serial No. 239,345, filed January 3, 190.5, of which this applicm tion is division] In the Ol'lglilitl' application referred l: have shown several forms of reilwsy-niotors in which s plurality of are sr ranged-upon tbefcsr sxles end the truckfra-nie forms pcrt of the magnetic drouit, the side bore of the truck frames being; connected by transverse psr'tit is arranged between the srmsturos on edjs 1i; axles which form parts of the nis ietio circuits.

These side bars are connected midway between the axles by a transverse steel or iron partition e, forming part of the maqnetic circuit for the four motors shown, an the end bars 6 are ""Jnnected to the central partition c by parmature.

The combined truck and field-1nagnet frame is thus divided into four. comparti rents C C C C. The axle 2 has two armstures D D, secured to it and arranged with-, in the compartments C and C, respectively, and the axle two srmstures D and D", secured to it and srrsnged within, the compartments v and 6", respectively. Pole-r pieces-8 ore arrmged upon the end bars 6 opposite the adjacent ermstures, and pole piec s 9, ha ing windi l0 thereon, secured to trensvr srtitions e and project toward the srrnstnres in the adj scent compartments of the frame. The partitions e form parts of the magnetic circuitsfor the two motors in the compartments at each side of said partitions. The partitions c in'Fig. l-nisy be provided with central bearings for the axles, if desired.

In Fig. 2 the construction and arrangement of the combined truck and field frame are the same as in Fig. 1; As shown in Figs. 2 and 3, however, befirings 5 are arranged in the lon gitudilial partitions c and the srmstures D and l) upon each axis are mounted upon sleeves 15, so tlietthey may rotate upon the .axles 2 end 3.

A car-wheel 4 is secured to each sleeve and rotates with the adjacent ar- It will be seen, therefore, that all of the car-wheels are driven independently by' the srmatures. The object of this construction is to permit the car-truck "to turn on sharp curves without slippage of the Any desired number of axles and partitions wiih pole-pieces between the axles may be added to the truck, and for such'purposes as transient-ables, whereextended-vies are providedwith more then two wheels to run on severg l tracks, more than two srmstures may be plirced on each axle, the pole-pieces on the transverse bars of the frame being correspondingly increased and thelongitudinel erti'tions being also increased, if desired,

W hat I claim as new, and desire to secure by Letters Patent, is i i I 1. In a motor-truclg the combination with parallel sides, and two arniatures, and wheels mounted on. each axle, of s combined field and truck frame comprlsln side bars supported upon the axles, ssi frame having" also transverse bars, connected to the side bars, arranged at opposite sides of each axle, pole-pieces upon said transverse bars opposite the several arniatures, and a partition extending lol'igitudinally' of the truck between ti '2 arinatures on the several axles and connect i to said transverse bars, said bars and partition forming parts of the magnetic circuits 4 2.
