HANGING- CARRIAGE FOR CHILDREN.

Specification of Letters Patent No. 21,012, dated July 27, 18 58.

same.

Similar letters of reference indicate like parts in both figures.

This invention consists in forming the springs of the chaise and the axle or bearings-of the wheels of a single rod of iron or steel bent or curved in a peculiar way as hereinafter fully shown and described, whereby the construction of such devices is much facilitated and a superior article obtained.

To enable those skilled in the art to fully understand and construct my invention, 1 will proceed to describe it.

A represents the draft-pole of a childs chaise or gig, and B is a rod of round iron or steel which may be one-half inch in diameter. This rod is bent at the center to form a sort of loop a, to serve as a proper means for securing the rod to the pole A, which is done by driving staples 6, into the under side of the pole, the staples encompassing the loop. The rod projects at right angles from each side of the loop a certain distance, as seen at c, 0, Fig. 2, and is there bent so as to form coils d, to serve as springs; and each end of the rod is bent so as to project back nearly at right angles with the parts 0, c, as shown by e, e; and the extreme ends of e, are bent outward at right angles as shown by 7, said parts f, serving as arms for wheels C. This rod B, bent as described, forms in connection with the wheels C, G, the whole of the running gear of the chaise. This rod may be curved or bent quite expeditiously, and a much simpler and better article is obtained than by any of the usual modes of construction with which I am acquainted. A very elastic spring is obtained, and one wheel is allowed to yield or give independently of the other; so that, if one wheel is raised in consequence of passing over an obstruction, the other will not be tilted or cramped so as to be suddenly strained thereby.

The coils d, may be of any suitable diameter; but as the body I) is secured to the back end of the pole A, as shown in red, Fig. 1, and the weight is placed at a considerable distance from the coils d, a suflicient degree of elasticity will be obtained with coils of quite small diameter.

I am aware that spiral springs have been applied to vehicles and arranged in various ways, both singly and combined with other forms of springs. I therefore do not claim broadly and in the abstract, the employment or use of spiral springs in childrens vehicles; but

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

Forming the springs of the chaise and the axle or bearings of thewheels C, of the same, by means of a single rod B, bent and applied to the device as herein shown and described.
