eUIoKuDnMoUNTABLE Application led July v9,

This invention relates to quick deinountable toy constructions andfis fully described in the following specification and shown in the accompanying drawings,y in which: 6 Figure 1 is a front elevatioinvpartially in section, of a front wheel Of a pedal car embodying the invention;

Fig. 2 is a vertical -section on the line 2v of Fig. 1; e

Fig. 3 is a horizontal section on the line 3 of Fig. 1;

Fig. 4 is an enlarged vertical section through the front wheel;

Fig. 5 is a section on the line 5 of Fig. 4;

Fig. 6 is a partial section similar to Fig. 4, but showing a modified forln of the circular construction;

Fig. 7 is aside elevation of the axle;

Fig. 8 is a sectiony on the line 8 of Fig. 6; and

9 is a detailed view of the inner end of thev p-edal crank as viewed froin line 9 of Fig.r 6. y f n The enibodiinent illustrated in Fig. 1 coniprises a front wheel 10, journaled as will later bedescribed, between front fork meinbers 11 which are secured to a tube 12 by ineans of a bolt 18. rlhis tube is journaled in a bearing consisting of a sleeve 14 and upper and lower dish-

ed plates

15 and 16, the whole being secured to Lthe platform. 1i" by means of bolts 18.

The tube 12'preferably 'terminates flush with the top of the sleeve 14 and is readily a insertable in .and removable from this sleeve.

A steering shaft 19 is insertable into the hollow tube`12 and has a slot 2O in the lower end which passes over the bolt 13 so that as the boy operating the device grasps 'the Lie handles 421 he inay turn the shaft 19 and through this the front forks 11 and front wheel 10 to .steer the pedal car shown.

A spring 22 (Fig. 2) issecured to the lower end of the tube 12 by ineans of av rivet 245i and carriesv a plunger 24 which passes through an opening in the side ofthe tube 12 and is adapted to engage a recess or de pression 25 in the shaft 19. The washer 26 is placed above the flanged sleeve 14 and te a y.snap ring 27 is placed a little above th-e washer in a groove 28 in the shaft 19.

To assemble the device as shown the tubel 12 is inserted from below into the sleeve 14 v34 areengaged by the plungers 35 w TOY CONSTRUCTION.

and the shaft 195 and is inserted from yabove and pressed down until the plunger 24 snaps into the rec-ess 25.' f f To reinove'fthe steering shaft and front fork lthe operator pulls up on the steering shaft 19 until the recess 25 is withdrawn from beneath the plunger 24 when the shaft and front forlr can be removed' froin kthe sleeve 14. Thus a quickand easy inethod is provided for assembling and disassembling this unit of a toy vehicle such as the pedal car here illustrated. rilhis is ofl considerable importance in vehiclesof this type to ship the parts disassembled .and to quicli-kv ly and easily assemble them before using.

In Fig. 4 is .shown a somewhat similary method for dissfsseinblingy the front wheel 10 froin its pedal cranks and fronithe steering fork 11. rlhis wheel consists of tw'o ,oppositely dished disks 29 which arey mounted upon ay hollow shaft 30 preferably of polygonal cross-section. A spacer Slis secured to one side of this shaftby means of a rivet 32 and serves asv ay spacer for the disks 29.

Cranls'of a squareor otherpolygonal cross-section are fitted intothehollow shaft 30 `and have recesses 34 therein which are se n adapted to 4engage plungers 35 which are carried` by springs 36, the springs being fitted to the shaft 30 by ineans of a rivet 37.

The .crank 33 is given a fairly7 clos-e iit in the inner race ineinber 38 of a ball bear-v Y ing 39 which is' carri-ed in .a housing 40. the

latter being secured to the lower end of the l fork 11.

.To disasseinble the construction'shown in F igj4, the cranks 33. are removed by a strong pull on each which withdraws it from the shaft 30. thereby pfn'niittingthe wheel 19 to be withdrawn from the fork 11. ln ree assembling, the wheel 10 is placed in the position shown in Fis; r4 and the eranlrfi` S3 inserted freni the side so that the rece es u hich will retain the cranks in place until suf-- ficient force is again used to withdraw them. @wing 4to the squared section of the oranlr'f; 33 and the squared hole into which these lit? thecranlrs will cause the shaft 30 to turn with them and this in turn, owing to its squared cross-section fitting into the flat-tened hole in the disks 29 will drive the front wheel 10.

lll() ln Fig. 6 is shown a modilied form of this device in which the shaft- 30a is provided with turned journals 80" which fit into suitable bearings in the ends of the :front forl-s lla. llotches 30C `are form-ed in the turned ends 30" which are adapted to receive ears 33h on the round cranks 33a.

are yieldingly held by the same means as that which is shown in Fig. et and which has previouslj)7 been described. The outer surface of the shaft 30?L isjmade hexagonal. and a positioning plate BlfL secured thereon by means of a rivet 32e.

ldlhile I have shown andfdeseribed but a few embodiments of this invention, it is to be understood that it is capable of many modifications. Changes therefore in the construction and arrangement may be made which do not depart from the spirit and scope of the invention as disclosed in the appended claims.

I claim:

l. In a quiclndemonntable toy construction, a hollow member, a driving member inserti'ble therein, coacting means for preventing relative rtation of said members, and yieldable means for holding said driving member in said hollow member but permitting its withdrawal when a pull of more than a predetermined amount is exerted.

2. In a quick-demountable toT construction, a hollow member, a driving member insertible therein, coacting means for preventing relative rotation of said members, and a spring-pressed plunger carried by one of said members and 'engageable in a depression in the other for holdingksaid driving member in said hollow member 'but permitting its The cranksy withdrawal when a pull of more than a predetermined amount is exerted.

3. in a quick-demountable to)7 construetion, a hollow i iember, a driving member insertible therein, enacting means for preventingl relative rotation of said members, a spring-pressed plunger carried by one of said members and engageable in a depression in theother forholding` said driving,I member in said hollow member but permitting its withdrawal when a pull of more than a 'predetermined amount is exerted, and means -imiting the inward movement of the driving member into the hollow member.

4. In a toy vehicle, a shaft, bearings therefor, a wheel, said shaft having' longif tndinal splines fitting into corresponding: openings in said wheel for securing` said wheel on said shaft.

5. In a toy vehicle, a shaft ha fing longitudinal splines, and a double disk wheel, said disks having openings fitting said splines and means for positioning` said wheel long ritudinall'jyv of said shaft.

(i. ln a tov vehicle, a shaft having longitudinal splines, a double disl wheel, said disks having openings tting; said splines and means for positioning` said wheel longitudinally of said shaft, and bearings at the ends of said shaft.

T. n a toy vehicle, a shaft having longtitudinal splines, a double disl: wheel, said disks havingi openings fitting said splines and means for positioning said wheel longitudinall57 of said shaft, the ends of said shaft being turned to form journals, and bearings thereon.
