WILLIAM STEWART, OF HARTFORD, CONNECTICUT.

IMPROVEMENT IN CHILDRENS CARRIAGES.

Specification forming part of Letters Patent No. 150,984., dated May 19, 1874; application filed January 2, 1874.

To all whom it may concern:

Be it known that I, WILLIAu STEWART, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Baby Carriages, of which the following is a specification, reference being had to the accompanying drawing, which is a side elevation of a carriage embodying my said improvements.

The carriage has two duplicate racks, a, rigidly attached to the rear axle b, and pivoted, at least by preference, to the front axle 0. Near the front of each reach starts a spring, d, attached to the under side of the carriage, and to the upper side of the reach.

Further back in each reach starts another spring, 0, attached to the top of the reach, and either to the bottom of the carriage at the rear, or to an arm, f, projecting therefrom.

The invention consists in the combination of the reaches, springs, and body of the carriage, the whole making a cheap and simple arrangement, giving a very elastic motion to the carriage body.

What I do not hereinafter claim I admit to be old.

Since making this invention I have been made aware of the United States Patent for childs carriage, to J. A. H. Ellis, dated June 22, 1869, and I wish to state expressly that I do not claim his invention as mine. In his case he makes springs of his reaches, and his springs, which connect these spring-reaches with the body of the carriage, cannot operate unless the reach is a spring; and he expressly claims as his invention a combination, one element of which is the parallel springs, meaning the reaches, and saying that they form the reach and sole connection between the front and rear axles. Now, in my invention I make these reaches rigid, with no spring, and i for the express purpose of preventing the reach from counteracting the effect of the springs, as it might do if it were elastic. Its springing motion would be mainly given by the passing of the wheels over stones and other obstacles in the path of the carriage, and the effect must often be to counteract and neutralize the springing motion of the other springs, and to cause the carriage body to stop in the midst of a gentle undulation with a motion much like asudden jolt. Not only this, but my springs are so disposed as to make the undulation of the rear part of the carriage, where the child sits, the greatest, this part being, so to speak, at the long end of thelever, thus softening, to the greatest possible extent, all jolts and jars; while if, as in Ellis case, the-springs are adjusted to throw both front and rear up and down alike, this softening of jolts and jars does not take place to the same extent.

The shape of my springs is essential to their complete success. It is essential that they should be lever-springs, in distinction from any other, or reflex, as in Ellis case, or elliptic springs; and it is essential that they be attached to rigid reaches; and

I claim as my invention The combination of the rigid reaches a, the lever-sprin gs d e, lying in the same line of direction with the reaches and the body of the carriage, all as and for the purposes set forth.

XVILLIAM STEWART.
