Letters Patent No. 98,351, dated member 28, 1869.

mrnovnmnzv'r m cnmmmn's camera The Schedule referred to in these Letters Patent and making p'u't oithe samc To all whom it may concern:

Be it known that I, BENJAMIN P. CRANDALL, of the city, county, and State of New York, have 'invented a new and useful Improvement in Childrens Carriages; and I do .hereby declare that the following is a full, clear, and exact descriptiouthereof, snfficient to enable others skilled in theart to which my invention appertains, to make and use the same, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a side view of a carriage, thelower portion being in section, as illustrative of my invention.

Figures 2, 3, 4, and 5, are views of detached parts, to be hereinafter referred to.

Similar letters of reference indicate corresponding parts in the several figures. Q

My invention consists in so pivoting the front axle, that the wheels thereof will conform to the inequali ties of the road, and, by means of a suitable spring, said axle will always be kept steady and square.

In the drawings A may represent the body of a carriage; B, the front wheels; 0, the hind wheels; and D, the reaches. which connect the front and rear axles, E F; all pf which parts may be of general form and construction.

G G represent the springs, which are of, elliptic form, as seen in fig. 4.

The ends of these springs are secured to longitudinal supports H, which are connected to the sides or hottcmot' the body A.

The crown or centre of the front spring G rests on a cross-piece, a, which is supported on the reaches D,

1 The rear spring G rests on a casting, H, which is made forked, soas to straddle the rear axle.

A bolt or pin passes through the crownof the spring G,' the casting H, and the rear axle, and thereby secures the spring in place, without the employment of the ordinary clips.

J represents a casting or block of wood, which is pivoted to the front' axle. It is constructed to stradper side,- grooves or spaces it, which fit or rest the forward ends of the reaches D.

The pivot 12 passes through the piece J, and the axle, and allows the axle to vibrate in a vertical plane,

the front wheels. It will be seen, that in using the perambulator, the

ities of the pavements, streets, or roads on which they may travel, and yet are kept directly to the front.

I arrange aspring, K, within the piece J, and connect it thereto, or to the reaches D, so that its two ends are free to point in opposite directions, and bear against the front axle.

It will be seen, that all shocks or jars on the front wheels are received by the spring K,'and prevented from reaching the body A. The spring also keeps the axle square. This is desirable in crossing gutters, holes, or ruts'.

In such cases, the hunt wheels andcorresponding parts of the carriage are lifted 'bodily from the ground. I

When they are returned, the wheels are caused to strike the ground fairly and squarely, and without .any shocks or jars.

The casting or block J may be dispensed with,'and, in lieu thereof, I canemploy bars 0, shown in dotted lines, fig. 1. These bars are pivoted to thereaches and the front axle, and are adapted to allow the oscillation of the axle, in a manner similar to that already described.

Other devices may be employed for the same pnr pose, the object in all cases being to admit the axle to l.

' oscillate in a vertical plane, in order to cause its wheels to conform to the inequalities of the ground, and thereby retain thebody of the carriage in a more horizom tal position than it assumes where the axle-is rigid.

The spring -K.is auxiliary to the springs G G. It not only keeps the front axle square, but assists the other springs to prevent shocks and jars reaching the body of the carriage.

Havingthus-described my invent-ion,

What I claim as new, and desire to secure by Letters Patent, is

1. In a childs carriage, the combination, with the bearing to which the reach is immovably secured, of the front axle, pivoted to said bearing, substantially as and for the purpose described.
