To all whom it'vnmy concern:

Jr., .a citizen of the United States, residing in e city of New. York,. county of Kings, andv State of New York, have invented certain new anduse'ful T Improvements in .Games and Toys, of which the following is aspecification, reference be-g ing had therein to the :accorgpanying drawings,-which-form a, artthere y Y My invention re atessto amesuand toys,;

and more particularly :to'ia c 2.551 of electrical toys. 1 v Y he main objectof niyinvention is to pro; yide an electrical vtoy s'imulating a 'rotarye'nk gine wherein a rotaryflarmature associated" with a balance-weight as a lily-wheel will be actuated from affixed electromagnet, which vmagnet will be energized and denergized synchronously with the rotation of the armature .in a manner to impart motion to the ah mature in suchrapid succession through the intermittent attraction of the armature by the magnet as to give with the aid of said balance-weight continuous rotary motion thereto.

Afurther object is to provide a toy electric motor which may be run with a very low e'lectrornotive force. 2 l

A stillfurtherobjecti s. to provide in'a tbf of this description a simple make-and-brea mechanism to intermittently energize the a "magnet.

still further object is w ovid a ma e and-break 1 mechanism .which may "he adusted as to advance or retard thelc'los'ing of the circuit energizing the electromagnet to control within "limits ture rotation.

the speed of the arms-1 A still further. obj ectis to'prov'id'ean armature which will be strongly attracted by the magnet and yet will not be so influenced by the residuary magnetism as to retard its rotation; and a, still further-object is to provide a scientific toy which will 'be simple and inex pensive to manufacture, which ma be ap-' plied to various uses requiring sma' 1 power,

1 and which will not be subject "to such disarrangemenths will permit of its readily' get-' ting out. of order.

The invention consists in such novel features of construction and combination of parts as are hereinafterset forth and de- Patent; V Y .'lpplicatlon mists, mime. Sariil'li'o. 296,291;

P tented-"Sept. 11, 19GB scribed, and more particularly pointed out in the'dlaimsfliereto appended;

Referring to the drawings, Figure 1 is a -front elevation of a toy embodying myinven .tion. Fig.2 is a sideelevation thereof. Fig.

.3is a section onthe line 3 3 hi Fig. '1. Fig. 5'1 is an enlarged view of the-ma'ke-and-break .60. mechanism,-and Fig.5 is a view 'fa modified -form o'fzthearmatureiand fly-wheel construction.

' Like letters theseveral views; 4

In theem'bodiment of my invention shown 'in the drawings I- employ an electromagnet comprising score a, havi spool-heads a" and fa permanentlysecured thereto anda wind- I 1 'ing '1) of insulated wire upon said core for en- .ergizing same. The core a and head a". are

refer to like parts throughout y Y preferably of steel, and the head a is prefer- :Ebl of brass and thinner than the head a"..

Inc osing the winding -b is a sheet-iron cylindrical jacket 0." The terminals'of the wind- .ing 1) are res ectively'in electrical connection i with one po e of .a source of electrical ener .as a 'batterycell (indicated at d) .and e head at. One poleof the core a, as a, passes through and projects beyond the head 6..

1 The head a carries oppositely-disposed fbr'ackets e e, one or both of whichis or are in, electrical connection/therewith, said brackets having suitable bearings therein for a shaft or axle f, made of me'ta-l, or placed in electrical connection with either or both of jsaid Lbrac'kets 0e. Mounted on said shaft-or axle f, 'between said brackets e (if and'extend- 'ing into-close juxtaposition to the protruding p0 e 0, of the core a, 'is an armature g. This armature is preferably composed olia plural- 'ity of steel laminae, as shown, forming a ce'ntral hub, and webg, carrying about the pertphery thereof asuccession of raised sections g spaced at" oints equidistant from eac'h other and pre erabl three 'innumber. The surface ofeach raise section preferably extends from'the web g" and rises in .-a gra ual curve in the direction of rotation of the armature to its hi hest point, descending substantially radial y of the armature to the startin -point of the next such section, 'formv oulder, as shown, although, as shown 5, if desired, said raised sections may each mere a portion projected from the web 5}, having a curved surface of 5:5 (not s provide-means va V, the engine, which 6 5 petsk with the brush h, thusei varying radii, as before described. This ar-' rangement and construction of the raised- 'sections '9 is designed to counteract any 7 effects of residual magnetism in the core c,v

5' tending to impede the continued rotation of the armature under acquired m'omentu'm.

' Whilethis armature is preferably laminated,

it may be cast or drop-forged in a single piece 15 not and energize it again to cause the attraction of the succeeding raised section 9 to,

continue the rotary movement of the entire armature. The requisite balanced weight may be in the nature of a heavy web gr in the :0 preferred form or in the form of a balance or or other means whereby the small power de- %y wheel 9 as shown in the modification in i 5. It is apparent that the armature 9 may be rotated solely through successive im-. pulses on the raised sections by the mag- 2 5 net and that to accomplish'tixis it is requi site that themagnet-core a should be energized and denergized during each complete the armature asmany times as rotation of I there are spools on said armature and that 0 the period or interval at whichit is energized each time must be at a time when. any two successive raised sections gfare unevenly spaced with relation to the protruding pole a? of the core a with the approaching raised 3 5 section the nearer in order to avoid the equal attraction of both such sections.- This makeand-break mechanism, preferably comprises, a brush h, mounted .on a bracket '11, from which it is insulated by arubber or vulcanite 40' bushing 71, said bracket preferably being mounted on the jacket 0, and a tappet-pla'te mounted on the shaftor axle f, comprising a plurality of tap ets k, so set as torespectively contact with the. brush h These tap- 4 5 pets corres 0nd in number with the raised sections 9 an are so set relative thereto and tothe shaft f as to cause their contact with the brush h to be as describedwhen the raised section approaching said core is the nearest 5o thereto, t e exact ositionih of said tappets varying with the ocation'o port. I V

The battery-terminals d d are connected direct] or throu h interposed-binding-posts ii own) with the terminal-'6 and;with

the screw orother means 71/, securing the brush it to the bracket i, respectively, so that the circuit will'be closed throu h said brush 1, the ta pet k,- the shaft or arse either of 6c the brac ets e e, and the head a.- Itis desirable-inn toy of thisdeicription .to g the speed rpowerof accomplish by means for regulating the instant of contact of the tap desire the brush-supingior retarding the energizing of themagnetrc corea and increasin or diminishinthe duration of the period 0 attraction. w1th a corresponding diminution or increase of the denergized period wherein-the armature rotates under momentum. This means comprises a bracket m, carried by the screw or other meansattaching'thebrush.h tothe; I

bracket '5, in the offset arm of which is a thumb-screw n, acting against. the tension of the brush. It will be observed that the" screw n is in circuit. withsaid brush, thus avoidinglany possibility of short-.circuiting and the necessity for insulating it. The herein-described make-and break mechanism is emgloyed becauseit is reliable and serves all t low cost. The shaft f is provided with a crank-arm 0 veloped=may be utilized in various relations, as for driving a propeller-shaft or the run: ning-gear of a'toy, beingin thenature of an impact-coupling common'to variousmechanlca toys.

trical toy is substantially as follow the proper batter connections having been 3 11181111612. It has been demonstrated that a single dryIbattery-cell, developing approximately one and one-half volts and eighteen amperes, wills flice torrun a toy for The operation of the herein-described elec-' e purposes required of it, whilev capable of-being produced ata very adein any a perlod in excess of ten ours. To start the toy, it is necessary to rotatethe armature hand until one of the tappets '70 contacts w1t the brush h, whereupon the circuit is closed, fiowingfrom the battery (1 andits terminal d to the screw h, the brush h, the tappet 7c to the axle or shaft f, either bracket .e e to'the head a, and through the coil bt the other batteryterminal (1 and the other battery-pole. As said circuit is 'closed a shoulder of one of the raised section 9 is approaching the protruding pole a of the core a and is attracted thereby. I As the highest point of the raised section assesfrom directly beneath said pole a? or t e. forward edge of said section ,so

passes the circuit is opened bythe escape of the tappet from said brush, thus permlttrng the armature "to-rotate under momentum of the Weighted Web g or'of the fly-wheel-g ,Any residuary ma pensated for by t.

ctism in said core is comi gradual increase of the gap between the pole aiiand the raised sec-"- tion.g,'dueto the-shape of the. latter, which result is accomplished without unduly diminishing the size of -the section.' As 'said section passessaid pole a the succeeding tappet :contacts with-the brush" h, again plosing the "circuit, with the result, as aforesaid, w th-the p succeeding raised section'g, thus contlnuing the rotation of the armature by ,aseries of impulses derived through the intermittent her advancenergizing of the electromagnet. If it be desired to increase the-velocity of rotation of the toy, the thumb-screw n is retracted, permitting the brushh to spring in close to the develops sufficient momentum to carry the armature during the interval when the magnet is denergized. t

It is not my intention to limit the invention to the precise details of construction shown in the accompanying drawings, as it is apparent that such may be varied to so adapt the toy as to develop motive power for various contrivances,
