Specification of Letters Patent.

Patented Apr. 4, 1911.

Application filed July 18, 1910. Serial No. 572,431.

To all whom it may concern:

Be :itknown that I, WILLIAM G. VIALL, a citizen of the United States, and resident of Bridgeport, in the county of Fairfield and' State of Connecticut, have invented certain new and useful Improvements in Toy Elec' tric Movements, of which the following is a specification.

This invention relates to new and useful improvements in toy railway electric motors such as are employed in miniature forms of electric locomotives, electric cars, etc., and designed to operate upon a suitable third rail track. 7

It is the purpose of the invention to provide av special form of frame, that will be adapted to accommodate the magnet, armature, gears, etc., and whereby the same may be contained within a comparatively small space and thus placed within the regulation size toy locomotive or car body; to provide a movement frame that includes the usual side plate members'for the support of the magnets,gears, shafts, etc., an additional side plates secured to but spaced from the before mentioned plates, to form a support for the armature shaft and an intermediate gear shaft, and further to form these outer plates in such shape as to best accommodate the driving wheels of the movement and engage and support the body of the locomotive.

Upon the accompanying sheet of drawings forming a part of this specification,

' similar characters of reference denote like or corresponding parts throughout the several figures and of which,

Figure 1, shows a side elevation of a toy railway locomotive designed to be electrically operated upon a third rail track and driven through an electric motor sup orted in the improved form of movement rame. Fig. 2, is a detached rear end elevation of the movement and frame shown in Fig. 1.

Fig. 3, is a side view of the movement and .body of the locomotive.

The movement proper one on each side. This placement of the movement insures its up er portion being housed within the hollow ody while'the top horizontal edge 11 of the outcrside plates 10 rest against the longitudinal shoulder 11 of the body. The cut away portion or curved under'edge 11 of the side plates form a downward extended. portion 11 of the frame, 'Which is arranged intermediate of and above the tread of the driving wheels and on the outside of the'flange of such wheels so as to permit the plates and frame to be seated inside of the outer face of the driving wheels.

Of the

movement frame

12 and 13 indicate the inner side plates and 14 the cross studs, for securing the plates in position. The two axles 15 and 16 are journaled in these plates and thus serve to su port the movement upon the driving wlicels 17. Gears 18 are also secured to these axles for the purpose of operating the same through the medium of an idler gear 19 loose upon the stud 20. This idler gear meshes with and is driven by a smaller gear 21 attached to the motor shaft 22.

23 represents the magnet which is securely fastened in the frame and 24 the field magnets intermediate of which the rotary armature 25 is operated.

26 represents a flexible shoe that projects down from the movement for the purpose of engagin a third rail or track, not shown, for making electrical contact.

The outer side plates 10 are secured to but- 7 as shown and further serve to engage the This additional space formed inside of the outer plates form needed room for the commutator 27 and brush 28 upon the one side and the before mentioned gears 18 and pinion 21 upon the other. a

An electrical movement of this kind having capacity sufiicient to draw a train of toy cars and built in the ordinary way, with two side plates only, could not be put into the limited space of a regular size locomotive body, since in order to acco modate the ear mechanism, armature, commutator;

rush etc., the said plates would have to be placed too far apart. With the additional plates situated below the top portion of the inner plates and set off therefrom as indicated all the parts are amply provided for and a very satisfactory and useful movetrack.

scribed the: combination of a frame, comprising side plates and cross studs for supporting the magnets, gears and shafts, and additional side plates secured to but spaced from the before mentionedside plates for supporting the armature shaft.-

2. In an electric movement of the class described the combination of a frame, comprising side plates and cross studs for supporting the magnets, gears and shafts, and

additional side plates secured to but spaced from the before mentioned side plates having a straight top edge and two concaved under edges to conform to the shape of the driving wheels. I

3. An electric movementof the class described the same comprising a frame including side plates and cross studs for supporting the magnets, gears and shafts, additional side plates secured to but spaced from the before mentionedside plates, an armature shaft journaled in said last mentioned plates, a commutator mounted upon the a'r' mature shaft and intermediate the plates in one side and a brush also situated intermediate the said plates on one side.

4:; An electric movement of the class described the same comprising a frame including side. plates and cross studs for supporting the magnets, gears and shafts, additional side plates secured to but spaced from the before mentioned'side plates, an armature shaft journaled in said last mentioned plates, a commutator and brush intermediate the two plates on one side, and train of gears intermediate of the two plates on the opposite side for connecting the armature shaft and driving wheel shafts.

5. In an electric movement of the class de-. scribed, the combination of a frame, come prising side plates and cross studs for supporting the magnets,fgears and shafts, and additional side platessecured to but spaced from the before mentioned side plates having a port-ion extended downwardly and intermediate of the driving wheels.
