UNTTEU @TATEfi FATE J EDWIN EWING, OF CLINTON, IOWA.

GO-CABT.

1,1as,o1e.

To all whom it may concern Be it known that I, EDWIN EWING, a citizen of the United States, residing at Clinton, in the county of Clinton and State of Iowa, have invented certain new and useful Improvements in Go-Carts, of which the following is the specification.

This invention relates to go-carts for children and has for an object the production of a simple, inexpensive, strong and durable go-cart of low cost and attractive appearance. Apparatus of this character as heretofore made, in so far as I am aware,

have always been provided with elliptical compression springs to resiliently support the seat where the same has been resiliently supported. These springs are very expensive and for that reason go-carts are frequently made without any springs at all, and are obviously uncomfortable and harmful to children riding .therein.

Another object of the invention is the provision of a novel spring system whereby the seat of the go-cart is resiliently supported by tension springs.

Another object of the invention is to prevent displacement of the tension springs due to bumps or sudden abnormal weights.

Another object of the invention is to pro vide a simple, economical and easily constructed rest for the go-cart.

Other objects and advantages of the invention will appear as the description to follow proceeds.

In the drawings: Figure 1 is a reduced perspective View of the go-cart complete. Fig. 2 is a front sectional view thereof. Fig. 3 is a side elevation of the go-cart with parts in section.

In the drawings: 1 represents the axle of the go-cart upon which is pivotally mounted the pulling handle 2 by means of the strap 3 which loops the axle, as shown in Fig. 2. Rigidly mounted upon the handle 2 and extending downwardly and rearwardly from the end thereof is the substantially triangular rest 4: which keeps the cart from tipping backward. Integral with the loop 3 and extending forwardly and downwardly is the rest 5 which is curved upwardly, as shown at 6, to join the handle and is secured thereto, as at 7. The rest 5 is provided with a pair of foot-rests 8 at convenient places. Supported upon the axle and affording bearings therefor, are a pair of arms 9 which are bent backward at their forward ends to Specification of Letters Patent.

form the loops 10, the axle being mounted in alined apertures in the loops 10, and thus giving a broad hearing at either end. The bent back portions of the arms are secured to the main portions of said arms, as indicated at 11, by pins 12 which form pivotal supports for the legs 13 of the U-shaped member 14:, the ends of said legs being mounted in the loops 10, as clearly shown in the drawings. The U-shaped member 14 is bent to form a loop 15 at the top middle portion thereof, in which loop 15 is pivotally mounted the rear end of the link 16, the forward end of which is connected to the handle 2. The seat 17 is secured to the support by the U-shaped member 14: and its weight is thus transferred to the arms 9 at a point spaced from the fulcrum of said arms upon the axle. The seat 17 is provided with a back 18 and with U-shaped side pieces 19 which terminate rearwardly in hook extensions 20 under the rear corners of the seat. Pieces 21 are provided to connect the back with the lugs 22 formed centrally of the side pieces 19. The arms 9 terminate at their rear ends in upwardly turned hooks 23. Between the hooks 23 and the hooks 20 are interposed coil springs 24;.

In operation, weight imposed upon the seat 17 will tend to depress the arms 9 rotating them upon the axle 1 without permitting the seat, and therefore the U-shaped member, to tip backwardly owing to the link 16 rigidly connecting the seat with the handle 2. The depression of the arms 9 will separate the hooks 23 and 20 expanding the coil springs 24; and thus resiliently support the seat.

I. have provided means whereby the extension of the springs 24: will be limited so as to prevent distortion of the parts or the straining of said springs in the event of sudden bumps or that an abnormal load is imposed upon the seat. This means comprises a flexible strap or thong 25 preferably made of leather but which may be a chain or any equivalent, which is longer than the coil spring 21 but short enough to become taut before said spring reaches a straining point or the parts of the machine can become distorted. The thongs 25 are attached at their ends to the hooks 20-23. The hooks 2023 are preferably formed by punching holes 20 and 23 in the corresponding parts and then making an inclined cut, as shown at 23 through the holes and then twisting the heads of the arms so as to skew the same with respect to the body thereof, after which the end of the spring can be easily slipped into the hole. After the spring is attached, the ends may be bent back into alinement with the body portion of the arms'9 or pieces 19, in which event the holes will be closed and it will be impossible for the spring to escape.

The legs 13 of the U-shaped member are partly cut through and offset as shown at 18; this prevents the arm 9 from swinging upwardly far enough to disengage the springs 24 when the carriage is wheeled rapidly over rough ground, or is subjected to sudden bumps. 4

Having now described my invention, I claim;

1. In a go-cart, an axle having wheels thereon, an arm pivotally mounted upon said axle, a seat supported upon said arm, an extension spring connecting said arm and said seat, the point of support of said seat on said arm being between said axle and said spring.

2. In a go-cart, an axle having wheels 7 thereon, an arm mounted on said axle, a

seat, a strut supporting said seat and pivotal ly connected to said arm, a coil spring connecting said seat to said arm and an offset on said strut to limit the movement of said arm relatively thereto in one direction.

3. In a go-cart, an axle, a pair of arms thereon, a handle and a rest mounted on said axle, a 'U-shaped member carried by said arms intermediate the ends thereof, a seat supported on said U-shaped member, a pair of springs connecting the-ends of said arms with said seat and a link connecting said seat with said handle.

4. In a go-cart, a pair of arms each having an end doubled back, alined apertures in.

said ends to ail'ord bearings, an axle in said bearings and having wheels, a seat, struts mounted on said arms and carrying said seat, springs connecting said seat with said arms and means on the struts to limit the movement of the arms relatively thereto in one direction.

5. In a go-cart, a pair of arms each having an end doubled back, alined apertures in said ends to afl'ord bearings, an axle in said bearings and having wheels, a seat, struts mounted on said arms and carrying said seat, springs connecting said seat with said arms and means on the struts to limit the movement of the arms relatively thereto in one direction, and means for limiting the movement of the arms in the other direction.

6. In a go-cart, an axle having wheels thereon, an arm mounted on said axle, a seat supported on said arm and an extension spring connecting said arm and said seat, and an unexpansible member connected to both ends of said spring to limit the extension thereof.

7. In a go-cart, a pair of arms having bearings for an axle, and said axle having wheels, a seat supported on said arms, coil springs connecting the rear of said seat with said arms, a handle and a link connecting the seat to the handle.

' In witness whereof, I hereunto subscribe my name to this specification in the pres ence of two witnesses.
