HENRY` J. HEIDER, OF CARROLL, IOWA, ASSIGNOR TO HEIDER MANUFACTURING COMPANY, OF CARROLL, IOWA, A CORPORATION OF IOWA.
Gassman-weeen.
To all lwlwm it may aoncem:
Be it known that I, HENRY J. Hmmm, a citizen of the United States, residin at Carroll, in the county of Carroll and tate of Iowa have invented a new and useful Coaster-Wagon, of which the following is a s ecification.
his invention has reference to coaster wagons, and its object is to provide a pivot or automobile axle for coaster wagons whereby liabilit of upsetting either in coasting or hau ing loads is practically eliminated.
In the ordinary type of fifth wheel wagons a short turn causes the front axle to move toward alinement with .the longitudinal centerline of the wagon, thereby greatly reducing the spread of the su porting base of the wagon, wherefore, t e wagon very easily upsets. In accordance with the invention stub vaxles are provided at the ends of a rigid bolster structure and these stub axles are so constructed and mounted that when the wagon makes a turnthey move out of parallelism so that there is compensation for the difference in turning movement or travel of the two wheels. The result is that the wheel base crosswise of the wagon is not materially shortened when the wagon is making a turn and the stability of the wagon remalns constant whether moving straight ahead, or making the shortest turn of which the wagon is capable. This is an important consideration in coaster wagons because such wagons are customarilyA used by children in their lay and children are liable to be hurt y the upsetting of their wagons. Also, when the wagon 1s used for conve ing loads upsetting is not infrequent 1n making short turns.
The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

Fig. 1.
rig. 4 is a section on the line 4 4 of F ig. 1. `ig. 5 is a perspective view of one of the wheel spindles and its pivotal bracket.
Referring to the drawings, there is shown a bolster 1 of a type used in to wagons, bolster may conveniently, t ough not necessarily, be made of wood. Fast to the bolster 1 is a skeleton sub-bolster 2 shown in the drawings as composed of flat bars 3, 4 respectively, separated by spacer sleeves 5, 6, the spacers 5 being arranged in s aced relation to each other on opposite sides of the center of the sub-bolster, thus bein on opposite sides of the central spacer 6, w ich latter may be shorter than the spacers 5 to accommodate certain parts.
Traversing the bolster l from top to bottom and also traversing the bars 3 and 4 and the spacers 5 are long bolts 7 provided at one end with heads 8 and at the other end with nuts 9. The bolts 7 serve to rigidly connect the bolster 1 and sub-bolster 2 so that these two structures together effec tively constitute a single bolster.
Extending between the end portions of the bars 3 and 4 are upright bolts 10 constituting pivots for brackets 11 each having an outstanding wheel spindle 12 thereon.
The brackets 11 may be in the form of castings or forgings of a length to extend from the bar 3 tothe bar 4, and each casting 11 has at one end an angle extension 13 comprising two arms 14 and 15 at substantially right angles to each other. At the other end of the bracket 11 is another arm 16 extended in the same direction as the arm 14. The arms 14 and 16 have registering perforations 17 and 18 respectively, which, in the assembled structure, are traversed by the pivot 10 connecting the bracket 11 with the bars 3 and 4 of the sub-bolster 2, so that the bracket 11 may turn about the bolt 10 as a pivotal support. In the assembled structure the arms 15 project in a a link 19 at the front of the bolster so that the two arms 15 together withl the brackets 11 and spindles 12 are constrained to move simultaneously in one direction or the other. The junction between the link 19 andthe arms is by way ofpivots 19,
The spacer 6 is mounted between the bars 3 and 4 by means of a bolt 20 which also serves to hold the corresponding ends of two straps 21, 22 to the sub-bolster between the spacer 6 and the bars Brand 4. The link 19 is also held to the strap 21i by means of a pivot pin 23 having a certain amount of play len thwise of the strap 2l by reason of a longitudinal slot 24 formed in the strap 21 and traversed by the pivot pin 23. The straps 21 and 22 extend forwardly of the structure, the strap 22 rising toward the strap 21 and the two straps being joined at their forward ends to a yoke 25 introduced between them, rivets 26 servin as the fastening means, A pole or han le 27 is pivoted by a bolt 28 to other straps 29, in turn connected to the arms of the yoke 25 by a pivot bolt 30. Thus the pole or handle 2 is flexibly connected to the yoke 25 with the latter rigidly connected to the straps 21 and 22. The straps 21 and 22, constituting a steering bracket, are movable about the bolt 20 as an axis and such movement is imparted to the wheel brackets 11 simultaneously, whereby to impart steering movements to the front wheels.
When the vehicle is going straight ahead the wheel spindles 12 are in substantial alinement crosswise of the vehicle (Fig. 1) but have a slight slant their outer ends (Fig. 4) because of the differencein length of the arms 14 and'16. This is advantageous in making the vehicle steer easier than if the wheels stood upright and parallel.
When the vehicle is turning to one side or the other, the spindle on the inside of the turn has a different turning radius from that on the outside of the turn. In order to cause the proper turning of the wagon the inside spindle, that is the one on the side toward which the wagon is turning, is moved about its axis of turning to a greater extent than the outside spindle, since the outside spindle is further away from the center of a given circle of turning than the inside spindle and consequently requires a longer radius to tollow the line of circle truly. This produces movements in turnino* carrying the link 19 out of parallelism with the bar 3 in front of which it is located and it is for this reason that the slot 24 is provided to allow for the lack of parallelism between the parts in turning.
A feature of the invention in which it distinguishes from other devices is the turning of the spindles simultaneously to differ- -generally forward direction and are joined downwardly toward A holsters together, brackets at ent extents upon their'axes so that the wheel toward tlieinner side of the turn hasashorter radius of turning than the outside wheel. 'l'lie structurev provides for the maintenance ot' a broad basic support in turning, thereby preventing the narrowing of the basic support and the lack of stability inherent in fth wheel types of front axles. Another feature is the arrangement of the tongue pivoted at the rear to the front bolster in the longitudinal center line of the vehicle and extending forwardly and there connected tosteering mechanism controlling both front wheels for steering so as to move the inside wheel to a greater extent'than the outside wheel in the turn, while the joint in the tongue permits the use of the tongue for drawing the wagon or for steering the wagon by an occupant thereof, with the steering in either instance of such stability that there is no danger even at high speeds of the wagon upsetting sidewise on making a relatively sharp turn. The joint in the tongue is sufficiently far in advance of the front wheels'to provide for the steering of the wagon solely by swinging the steering bracket to one side or the other, at the same time providing for pulling the wagon'by means of the outer end of the tongue.
