V This invention relates to a bell ringing unit for embodimentin toy locomotives of eitherthe mechanically or electrically "driven type to simulate the soundof the bells on large passenger and freight service-locomotives now infgeneral .use, and has for its general object to provide a practical unit of this character which is. of relatively simple, inexpensive construction, which may readily be installed on existing-types of toy locomotivessubstantially without alterations there to, andwhichis thoroughly reliable, positive and efiicientin operation.

i Another object of theinvention is to provideza bell ringing unitwhich is strong and durable, which is readily capable of being mounted in a concealed and protected position within the usual cab or at another convenient point on a toylocomotive, which derives its actuating power-from the propulsionmotor of the locomotive, and which requires only anegligibleiamountof power'for its actuation. v {Withthe foregoing and: other objects in view, which will become more fully apparent; as the nature of the invention is better/understood, the same consists in the novel features of construction, .1 combination and arrangement of parts as willbe hereinaftermore fully described,illustrated in the accompanying drawing'aiid'defined inthe appended claims. m..-" -f ,r l

Present insmn e hw we innite' .is illustrated as a spring; motonmounted in a -frame 1 0 and inclusive of a. driveigear 1f1" operatively. connected through; gearing, designated generally as 12 ,with the axle 13fof one pair of the locomotive. :drive wheels, 14.

' The bellringing unit O comprisesvessentially a bell 15 and a cooperating clappenltl.

In the present instancelthebell ismounted on the supporting arm17 of a substantially L-shaped bracket 18, whoseattaching arm -l9is suitably secured to the power unit frame '10, or to some other convenient part of the locomotive structure, to dispose the bell ina suitable operative position. For example, as shown, the arm. 19 of the brac-ket 18 is secured across the top of the frame atlthe rear end thereof to support the bell in a protected and substantially concealed position within the cab 20 of the'locomotive,

The clapper 16'Inay conveniently be formed from a length ofheavy wire bent as shown into substantially Y shape, one arm 21 thereof constituting a striker forfcontact with the bell 15, and the other arm 22thereof being of relatively greater length and constituting a finger for cooperation with lugs 23 carried by thegear wheel 11 whereby striking move-' mentsof the efi'ected- Q The clapper 16. is resiliently supported arm 21 against the bell. 1.5 are lromthe arm 19 of the bracket 18 through the instrumentality of a spring arm 24, said arm" being secured at its forward end by. arivet arm and at its rear endbeing bent into, U-

'andiswing the arm 22 to actuate the clapper.

That is tosay, when the clapper is in its normal position as illustrated by full lines in Fig. 4:; the free end of the c'lapperarm is disposedlinthe 'pathof movement of the-lugs 26, and the length of theclapper arm 22 and the spacingof'thelugs 23 is suchthat the arm 22 Will. be moved a limited amount by each lug and then will spring by said'lug to its normal or substantially its normal. position to be pi'ckedfup and again moved in the same ma-nnerby-each succeeding lug. In this connection it will .be "observed by referencev to 1. .i'g..3 that'the arms21,2:2 ofthe clapper are bent to extend laterally outward relative to each other whereby the'striker arm 21 6K. tends within'the'bell for cooperation therewith and the arm 22 extends across the edgefl of the bell into cooperative relationship with th g 2 Y i i 1 .The operation of the device is apparent and asfollows: Assuming the clapper to be in its normal position as shownin full lines I in Fig. 4' and'the gearwheel ll to be rotating in thedirection of the arrow a, which is the directionof rotation of said gear. wheel when the locomotive is moving forward, it will be observed thatthe free, end of the arm 22 will be engagedand moved by one of the lugs 23 tofthe dotted line position as permitted by u ward flexing ofthe spring arm 24 with consequentmovement of' the free end of the striker arm 21to' a position spaced from the bell .15. Upon slight continued movement o'fithe gear,- wheel 11 the lug in engagement with the arm'22. moves acrossithe free end of said? armQand releases the same, whereupon the energized spring 24- inreturning the clapper to its normalipositioncauses thefreeend oft he striker arm 21 to strike the bell and produce .a ringing sound'siinulating the soundofthe bell of a large locomotive. At

' the same time the spring arm 24L acts to cause the arm 2l'to strike the bell it returns the arm 22,.to..its normal full line position .where itfis picked up by thenext lug 23 and the ..opera 'tiOn i'srepeated; so that during travel of the They are. disposed locomotive the bell is repeatedlyrung is manifest. Inthis connection it is to be noted that the lugs 23 aresospaced apart that as the arm 22 returns to its normal position",

during normal travel of the locomotive and rotation of the .gearwheel-ll at a normal rate of speed, each successive lug engages the arm 22 substantially simultaneously with or immediately following striking of the bell by the arm 21. "Consequently any chattering of the" striker "arm against the bell and any dulling of the ringing; sound due to'the striker arm remainmgin contact with the 7 bell is effectively avoided In" other words, each lug 23 operates to produce only a single blow of the striker arm. against the bell and as a consequence theringing sounds are sharp and clear andnentirely separate and distinct from one another. r

substantially the same operation takes place as has just been recounted The gear wheel 11 l andfthe arm 22 is. picked, upz -by 'eachisucc'es sive lug 23 being. elevated by each lug to flex thespring '24s upwardly and move: the striker arminto' aipositi'on spaced from. the
