CHILDS WHEEL-ED VEHICLE Filed Sept. 19, 1934 2 sheets-sheet 1 l VENT) Patented Feb. 18, 1936 STATES 6 Claims.

--This invention relates to improvements in toys and more particularly to vehicles for children.

The main object of the present invention is to provide a simple, efilcient and inexpensive vehicle for children designed to stimulate in the child operating the same a healthy muscular condition of the body and to bring into use all the faculties of the child for wholesome recreation.

The conventional toy vehicles designed for children particularly toy scooters, velocipedes and similar arrangements are at fault when considered from the standpoint of physical culture for the child; the leg muscles alone are exercised in the course of foot-pedaling the vehicle, while other muscles lie dormant. Children as a general rule to not exercise themselves properly when at play. In order to provide a type of vehicle which is designed primarily to exercise most muscles of the body I have devised the present invention.

A further object of this invention is to provide a vehicle so shaped, constructed and designed that it is propelled by a body movement of the child which exercises all of the back muscles, leg muscles, muscles of the arm, of the neck and other parts of the body, including the abdomen. The operation of this type of vehicle by the child produces a movement forwardly of the machine and a swaying movement of the body of the child, at the same time, so that it will readily be seen that the physical culture value of the vehicle is stressed keenly.

Another object of this invention is to provide a vehicle for children in which the seat is given a fore and aft movement as the vehicle is propelled forwardly so that the torso of the childs body undergoes a wide range of muscular movements in the act of vehicle propulsion. As a result of the operation of this vehicle it will ,be seen that it is inevitable for the child to be in afit physical condition after using the vehiole for a short period of time, thereby bringing about a healthy invigorating condition in the child as a result of mere play.

. A still further object of this invention is to provide a vehicle in the nature of a velocipede which is propelled by the seat portion of the vehicle instead of by means of crank pedals which is the usual method.

--Another object of this invention is to provide a velocipede which provides an up and down movement of the seat thereof for the purpose of stimulating muscular activity of the childs body.

A further purpose of this invention is to coordinate the operation of the foot pedals of ,a velocipede with the seat movements thereof so as to cause the seat to reciprocate as the vehicle moves forwardly or backwardly.

Another purpose of this invention is to provide a vehicle which has running boards upon which the feet of the child rider can rest while other portions of the childs body motivate and operate the propulsion mechanism of the vehicle.

A final object of the present invention is to provide a three wheeled vehicle with steering mechanism for exercising the muscles of the hands of the rider, and seat operating mechanism acting in time with the propulsion mechanism of the vehicle for exercising other parts of the childs body so that as the vehicle is put into use progressively the rider experiences physicaLac tivity.

With the above and other objects in view my invention consists in the combination, arrangement and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

Figure 8 is a top plan view of the vehicle shown in Figure 4, and

Figure 9 is a front elevation of the vehicle shown in Fig. 4, some parts appearing fragmentarily.

I have found after considerable experimentation that a vehicle in the nature of a child's velocipede can be constructed in such a manner as to be a source of pleasure from a recreation standpoint and also a source of physical betterment for the child at the same time. I find that the seat of the vehicle is that part which can be made to conduce most towards a fitting physical stimulation of the muscles of a person's body when movement is imparted to the seat and to the riders body resting thereupon or vice versa.

In the present drawings I illustrate various forms of vehicles in which the physical culture idea of vehicle propulsion is carried out. One form of such invention will now be described and reference will particularly be made to Figures 1, 2 and 3. The main body portion of the vehicle is box-like in construction and is hollow inside and has opposing side walls It and II and the inclining rear wall I2; this box is open at the bottom if desired. There is a rear shaft axle l3 designated to be rotated as hereinafter set forth. At the ends of this shaft axle are a pair of tired wheels I4 fixed to turn therewith. There is a top plate I5 which closes the box here and is removably secured by means of suitable fasteners IE to the top of the box. There is a crank shaft I! mounted inside of the box slightly to the rear of the center thereof, whose ends are operatively journaled in the side walls l0, ll of the box, the crank proper thereof being designated I8. A pitman I9 is pivotally connected at one end to the crank i8 and extends upwardly so that its other end may be connected to a seat 22, and particularly to a depending post or rod 2| to which the seat is secured. The lower porinternal bore is conical and tapers upwardly so that the post 2| is free to swivel in this bore in amanner soon to be described. At the ends of the crank shaft I1, outside of the frame or box of-the vehicle are fixed a set of crank pedals, the cranks being designated 26 and the pedals 21 thereof, being of usual construction. Inside of the box is a sprocket 28 fixed upon the crank shaft 11, and fixed upon the rear shaft axle I3 is another sprocket 29, and a chain 30 is trained upon both sprockets 23 and 29 respectively so that when the crank shaft [1 is actuated the rear wheels 14 will turn to propel the vehicle.

At the front end of the machine is a steering post 3| carrying the usual handle bars 32 of a velocipede. At its lower end this post is operatively journaled in a member 35 being shaped from a metal strap and arranged as shown in Figure 3. This metal strap has one end secured upon the front piece 34 of the machine, its intermediate portion doubled upon itself to provide a U-shaped part 35 through the arms of which the post 3| projects, and the lower portion of the metal strap is secured to the incurvate portion of the front of the machine. At the lower end of the post 3| is a fork 36 which straddles the steering wheel 33 of the machine when actuated by the handle bars 32 held by the operator of the machine. The axle 31 for the steering wheel is mounted in the fork 36. l

I refer now to the construction of parts of a changed vehicle illustrated in Figures 4, 7, 8 and 9 respectively. In this new form of vehicle I endeavor to show that the seat instead of moving up and down has a to and fro swaying action. The box and main body portion of the machine is the same as in connection with the vehicle already described. The box is hollow interiorly and has a bottom M cut away so as to provide a slot N therein. The seat 22 of approved construction carries a depending post 38 which is adjustably fitted into a sleeve 40 and locked adjustably into the latter by means of a set screw 4|; this sleeve is mounted upon a pivot pin 39 fixed upon the side walls It and H of the main box body of the vehicle. Secured rigidly at right angles to the lower end of the sleeve 40 is an arm 42, which may be forked out at one end and pivotally secured to a lever 43 which in turn is pivotally secured upon a crank 44 upon a crank shaft 45 whose opposing ends are secured to the side walls It] and II of the machine. The top board or plate l5 of the machine has a suitable slot P in which the sleeve 40 may swivel. Fixed upon the crank shaft 45 is a sprocket 46, and fixed upon the rear shaft axle I3 is a larger sprocket' tl, and there is a sprocket chain 48 which is trained upon both sprockets at the same time whereby when the crank shaft turns the chain will impart motion to the rear wheels.

The construction of the steering wheel mechanism of the vehicle is the same as that described in connection with the type of vehicle already illustrated in Figures 1, 2, etc. There is a still further type of vehicle which supplies different mechanism for propelling the vehicle shown in Figures 4, 7 and 8.

Instead of the direct chain drive from the crank shaft to the rear drive shaft or axle of the machine I now describe a combination of parts which will more efliciently answer the same purposes; Reference will now be had to Figures 5 and 6.

The seat with its post and pivoted sleeve 40 are constructed in the same way illustrated in Figure 4. The pitman 54 is pivoted at one end to this sleeve, and its opposite end is pivoted directly to a crank 52 fixed upon a crank shaft 51 whose opposing ends are journaled in the side walls I3 and I l of the vehicle. Fixed so as to rotate on this crank shaft is a small sprocket 5|, which meshes with a smaller sprocket 59 fixed upon the drive axle [3 of the vehicle. Therefore a more positive drive connection is provided for propelling the rear wheels I4 of the machine than the chain drive set forth herein.

In operation when it is desired to propel the type of vehicle shown in Figure 1 it is accomplished as follows. The child is seated upon the seat 22, with his feet upon the pedals 2! of the propulsion mechanism. As the pedals are caused to turn the crank shaft I! the crank l8 actuates the pitman or pusher 23 which in turn lifts and lowers the post 2| which carries the seat so that the child is lifted and lowered successively at the same time that the vehicle is moved forwardly. The child can himself accelerate the propulsion of the machine by his up and down bodily movement upon the seat concurrently with manipulating the pedals of the foot control for same.

In order to propel the type of vehicle shown in Figures 4, '7, and 8 as well as 9 the child will occupy the seat 22, with his feet idle upon the running boards 49 of the vehicle and by working the seat 22 back and forth, or'to and fro reciprocatingly he actuates the crank shaft 45 and turns the same so that by means of the sprockets and sprocket chain the rear drive axle turns and so do the wheels M for propelling the vehicle. As the sleeve swings upon the pin 39 it pushes forwardly in a cycle of movement a rigid arm 42, which has a swivel connection with the crank 44 of the crank shaft so as the sleeve swivels back and forth the crank completes one revolution and so in this manner the vehicle is propelled efficiently.

The construction of parts shown in Figures 5 and 6 permits the same swivelling to and fro action of the seat 22 and sleeve 40 to take place because it is evident that as the sleeve is propelled back and forth by the body of the driver that it actuates the pitman 54 which in turn actuates the crank 52 so that sprocket 5| turns and as it meshes with sprocket 50 the latter turns with it and in this way it will be seen that the rear driving axle and shaft turns continuously as the sleeve 40 is worked back and forth.

From the foregoing it will readily be seen that no matter which form of vehicle or velocipede is used the child propelling the same undergoes muscular activity in a manner not now permitted where the conventional velocipede is used. For as the seat rises and falls the center of gravity of the child is shifted and every muscle becomes active and removes tediousness and promotes exercising. Where the seat moves to and fro this motion serves to transmit propulsion to the vehicle and the body of the rider is again rendered active in point of muscular exercising. I do not confine myself to the exact details of construction save as pointed out in the appended claims.
