IMPROVEMENT IN CHILDRENS CARRIAGES.

Specification forming part of Letters Patent No. 145,298, dated December 9,1873; application filed August 26, 1873.

To all whom it may concern.

Be it known that I, J osEPH N. HAZELIP, of the city of Baltimore and State of Maryland, have invented certain new and useful Improvements in Garriages and other like vehicles, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to carriages and other spring vehicles, but moreparticularly to childrens perambulating carriages, and has for its object furnishing a cheap, simple, and desirable method of attaching the bodies and ar ranging the springs to the running-gear of said vehicles; and my invention consists of a separate metallic bracket-piece, having also a vertical box, for receiving the spring and the axlebearing stem, and these, being independent of the curved carriage-brackets, are manufactured and soldto the trade as carriage hardware, and,

- being a complete device, require only to be screwed onto the under side of the carriagebrackets and the axle inserted into the bearing-stems to make the attachment, without cutting into the bracket ends for the spring and bearing-seats, which not only increases the-expense, but renders the curved brackets Weak. and constantly liable to be broken ofi' at the ends; whereas the separate casting forms a firm seat for the carriage-brackets, and renders the carriage stronger and cheaper than hitherto made.

In the accompanying drawings, Figure 1 is a perspective view of a childs perambulating carriage with my improvements attached. Fig. 2 is a modification of my invention, showing the manner of hanging the body to the runnin ggear when elliptical springs are used without the aid of perchcoupling. Fig. 3 is an enlarged view of the spring-coupling used upon the front axle of childs carriage.

In Fig. 1, a, a are wooden brackets or arms, for coupling the body of the carriage to the front axle. Heretofore the front axle, with its wh eels attached permanently, has been coupled rigidly and without springs to the arms or braclc. 4ets a a, while the hind axle has been arranged to the body with springs. The front coupling at the axle, being unprovided with springs,

causes thecarriage, which is propelled from behind, to have a rough jolting motion, while the action of propelling it from behind deing one or the other of its front Wheels to ride up oi the ground almost continually. To avoid these and other objections to the usual mode of constructing this kind of carriage, I provide the wooden brackets or arms a a with box-spring couplingB B b b, as shown in Fig. l. These box-spring couplings serve the purpose of springs as well as that of securing the front running-gear to the carriage-body.

It will be observed that one of these couplin gs is connected to each end of the front axle, and forms a spring-bearing for its journals, the connection being made through means of spring piston-rod c, as seen in Figs. l and 3. It will also be seen that spring piston-rod c is provided with and operated by a spiral spring, c', confined within a case surrounding its upper end, and both the spring c and rod c are acted upon by the motion of iront wheels and axle. Now, the front axle being provided at its ends with a separate spring to act upon veach of its wheels independently, the tendency,

method of coupling the front running-gear can be readily used in connection with any of the usual modes now in use for attaching the hind spring and axle to thebody of the carriage.

My method of securing the hind ruiminggear to the body of the carriage may be readily understood by reference to Fig. l. E E are iron frame stays or brackets bolted securely to the bottom ofthe carriage-body. Each of these stays or brackets is so constructed as to receive guide-rod h, which passes through it vertically, and having a movement like that of a piston-rod. These guide-rods are for the purpose of coupling the hind axle of the carriage to the stays or brackets E E, the construction and arrangement of the brackets and guide-rods being such as to allow the body of the carriage to act vertically upon its springs, atl the same time preventing it from having a forward or lateral movement, which would tend to upset or rupture them.

The springs may be arranged to the carriage by placing them Within the rectangular opening in the stays or brackets E E, as in Fig. 1, Where they are secured to and operated by the guide-rod. This arrangement of the springs is a cheap and efficient one, particularly for childrens carriages; but Where it is desirable, the elliptical springs may be attached after the manner shown in Fig. 2, Where, it Will be observed, it is accomplished Without the aid of the perch-coupling in general use.

The casting for the spring is made in one piece, with a curved branch7 e, for attachment to the under side ofthe carriage-bracket a, and

a vertical box, B b, Within which the spring and bearingstem c are made, and between these a sea-t, f, is formed for the end of the bracket a, which render-s the attachment of the independent easting B conveniently and quickly made, and protects the carriage brackets from being broken ofi'.

Having thus described my invention, what I claim is- .lhe cast-iron bracket e and box B b, in com bination with bearingstem c and spring c', for attachment to and to form seats for the curved brackets a of childrens carriages, as and far the purpose set fort-h.
