SIGNORS TO \VESTERN CLOCK COMPANY, OF PERU, ILLINOIS, A CORPORATION ILLINOIS TOY OUTBOARD MOTOR DRIVING AND STEERING MECHANISM Application filed May 23, 1931. Serial No. 539,620.

Our inventionrelates to toy outboard motor driving and steering means and has for its objectthe production of such a driving and steering means which includes a motor and a propeller combination which is extremely simple to produce, using sheet metal in all its parts so that it can be manufactured and assembled at an exceptionally low cost. A further object is to produce a mechanism that can easily be taken apart and re-asse-mbled by the usual small boy without injury to any of the parts. 4

We accomplish these objects by the means shown in the accompanying drawings in which, 7

Fig. 1 is a top view of our toy mot-or driving means. I

.Fig. 2 is a: partial sectional view of our propeller driving means. I

Fig. 3 is a partial sectional view of the frame plate construction along a line 2 2 of Fig. 1. I

Fig. 4 is a cross sectional view along a line Fig. 5 is a front view of its driving means. 5 Y

Similar numerals represent the same parts throughout the several views. r

In the drawings 1 represents the main the propeller and 'frame plate and 2 an intermediate frame plate of the motor. The plates '1 and 2 are held together in proper positionon the shouldered pillars 4, 5 and 6 by means of the sleeve members 7 and 8 on'thesmaller part of pillars '4 and 5 respectively and the nuts 9, 10 and 11 on the lower threaded parts of pillars 4, 5 and 6 respectively.- An upper plate or strap 3 is held and positioned with respect to intermediate frame plate 2 on the upper part of 'pillars'4 and '5, said pillars 4 and 5' being staked or riveted into said plate. 3 as shown (see Fig. 3).

Formed in secondary plate 2 is a depressed part 12 forming a recess 13"for. the spring ratcheting means, described below.

Journaled in the intermediateframe plate 2 and strap 3 is the spring arbor 14 which is rotated in the usual manner. by the key 15. Said key 15 isdetachably mounted on arbor *14' "by mean's ofthe screw-threads 16. The

arbor 14 has the usual spring attaching pin 17 by means of which the driving or power spring 18 is fastened to said arbor 14, the other end of the power spring 18 being fastened on the pillar 4 as shown (see Fig. 1).

The spring arbor 14 has a ratchet gear 19 fastened on it adjacent to the gear wheel 20 which gear wheel 20 is journaled .on the spring arbor 14 and connected with ratchet gear 19 by means of the pawl 21 which is r journaled on the rivet 22 fastened to gear wheel 20, and furthersaid pawl 21 is resiliently held in engagement with the ratchet gear 19 by means of the click spring 23 shown (see Fig. 1). Said gear wheel 20 is held in .2, which shaft 30, also has mounted thereon,

the gear wheelv3l which engages with a pinion 32'0n the shaft 33 and which is journaled in

frame plates

1 and 2. Gear wheel 34 is further mounted on said shaft-33 whichgear wheel 34 is fastened to one end of. the pinion 32 as shown.

' Rota'tably and frictionally mounted in frame plate 1 is drive shaft tube 35 to which is fixed by means of collar 36 the steering wheel 37 which has the formed edge shown. Said drive shaft tube 35, may be moved to any steering position in azimuth by means of said steering wheel 37 and is yieldingly and frictionally held in said any given position by means of the friction washer 38 which is on tube 35 and held between the steering wheel 37 and the frame plate l.

Fastened to drive shaft tube 35 as shown, is one end of'e'xtension tube 39 into the other end of which. is removablv fastened the sleeve '40. Said sleeve 40 frictionally and removably holds in position the shank portion of the two members41 and 42which members form a splithousing for the

miter gears

43 and 44, and also form the lower bearing for the drive shaft 45. Said split housing is axially positioned with respect to drive shaft 45 by means of stop collar 46.

The upper end of said drive shaft 45 is journaled in frame plate 2 as shown (see Fig. 4). Said drive shaft 45 is driven by pinion 47 which is threaded on upper end of said drive shaft 45 and held by lock nut 48 in position of engagement with gear wheel 34 by which said gear wheel 34 said pinion 47 is driven.

At the lower end of drive shaft 45 is fixed the miter gear 43 which assists in positioning said drive shaft 45 axially and engages with miter gear 44. Said miter gear 44 is fixed on propeller shaft 49 which shaft is journaled in the split

housing member

41 and 42 andto one end of which propeller shaft 49 is fixed the propeller 50 by means of the hub 51. Said propeller shaft 49 is held in proper axial position by means of collar 52 as shown (see Fig. 4)

It is to be noted that

miter gears

43 and 44 are constructed in a novel manner, namely,the teeth being stamped out of the thin part of a turned metal blank and then cupped or dished to bring said teeth to the proper 45 degree angle.

When the power spring 18 is wound by means of the key 15 the mechanism can be held against rotation by means of a brake lever 53 journally and frictionally mounted on frame plate 1 by means of headed rivet 54 staked in said frame plate 1, the other end of said lever 53 engaging the teeth of the gear wheel 34. Said brake lever 53 may be used to start and stop the mechanism as desired. Q

Mounted on winding key 15 is a cupshaped member the function of w hich is merely to simulate the flywheel of a commercial outboard motor. The motor mechanism is encased by a drawn sheet metal casing 56 as shown, said casing fitting closely around frame plate 1 and held in position by means of

screws

57 and 58, which screws are threaded into suitable apertures located in frame plate 3 as shown (see Fig. It is evident that the removal of said

screws

57 and 58 permits easy access to the motor mechanism when required also the built up or divided'construction of the miter gear casing having the

parts

41 and 42, is such that is readily taken apart and put together again by the usual boy.

This devicevis fastened to the toy boat in the usual manner by attaching the frame plate 1 to the boat. In operation the spring is wound in the usual. manner by means of the key 15, the brake lever 53 being in position to give the boat the movement desired by means of the steering wheel 3?, when the boat with the complete mechanism is placed in the water and the lever 53' is moved so as to free the gear train, the propeller will move the boat accordingly.

It will be understood, of course, that while we have shown one form of our device that we do not wish to limit ourselves to the exact structure shown but wish to have it taken in a sense illustrative of all the forms that come fairly within the scope of our claims.
