IMPROVEMENT IN PATENT Orrrcn.

BROOKLYN, NEW YORK,

BABY-CARRIAGES.

Specification forming part of Letters Patent No. 136,607., dated March 11, 1873.

To all whom it may concern:

Be it known that I, SAMUEL MGINTIRE, of Brooklyn, Kings county, New York, have invented certain Improvements in Baby-Garria-ges, of which the following is a specification:

The object of my invention is to produce a carriage of highly tasty appearance, which shall be cheap and durable, as also peculiarly easy in its motions when subjected to concussions in all directions. The device for supporting the top is stronger than any other with which I am familiar, and allows peculiar facilities for adjustment, for inclining the top in difl'erent directions, and for instantly removing and replacing it when desired. The invention relates to a mode of attachingthe shafts to the parts which correspond to the perch and to the springs; to provisions for mounting and connecting spiral springs; to sockets for receiving a removable top; and to the construction of an adjustable top, adapted to be thereby supported.

The following is a description of what I consider the best means of carrying out the invention.

The accompanying drawing forms a part of this specification.

Figure 1 is a perspective view of the entire carriage on a small scale. Fig. 2 is on a larger scale. Its right side is an elevation, and the left side a section through some of the parts. Fig. 3 represents a portion of the top detached.

Similar letters of reference indicate like parts in all the figures.

A is the body; B B, the axles; O, the bent portion, which I term the perch, and the rear elevated ends of which support the handle by which it is operated by the attendant; and D, the wheels. The body is supported on four spiral springs, m. The top is supported by the curved wires 1) p, which match into sockets P P formed in the carriage on each side of the seat. E are four castings, which, respectively, embrace and connect the axles, perch, and springs. Each is traversed across the base by the tight-fitted axle B, and immediately above,

transversely thereto, by a tight-fitting perchpiece, 0 and above this each supports one of the spiral springs m by being threaded so as to receive the spring in the manner of a screw.

As I have represented these castings, the

springs m are screwed into threaded sockets;

if preferred, be made to receive the spiral spring on its exterior instead. In this latter 'case it is provided with a little screw-thread equally adapted to match the spiral spring.

The upper end of each spring m is correspondingly threaded into or upon a casting, Gr, screwed firmly to the body A. The hold taken by the springs min the castings E and G constitutes a firm support, and allows the springs m to yield not only vertically, but also laterally in all directions. Each hub Dis provided with two chambers, as shown. The spokes d are threaded obliquely into the ridges on the hub, as shown, so as to stand bracing, and may continue the same oblique direction, where they are threaded, into the rim D, with a conical or rounded face to the nut 01, which tightens the contact or, preferably, these spokes are bent just enough to bring their positions exactly radial at this point, so that an ordinary plain-faced nut may bear fairly. In either case the nut is slackened to allow the introduction of the spoke, and is set outfirmly against the rim to finish the wheel. The axles B are formed of gas-pipe. A short fillingpiece is welded in at each end, and the bearing is drawn, under a hammer or otherwise, to the proper tapering form, and turned and polished.

The body A may be made of wood, or of various other materials, and may be variously modified in form to suit the taste of the designer or the fashion of the period; but, in either case, the sockets P, which may be of small brass tube, are inserted in the positions shown, so as to be firmly and permanently set with their upper ends flush. These sockets receive the straight ends of the curved wires 0 p. The upper ends of these are threaded into a crossshaped casting, B, the vertical part of which supports the stem or standard tof the parasol T. The stem tis made of metal tubing, and is provided with the proper adjuncts for operating the parasol. The nut T is used to adjust the position. The threaded ends of the stem t firmly. Both wires 12 are formed with right-hand threads. It follows that when both are fitted so as to bear with proper force against the stem t thelatter, with its attachbut the upper portion of each casting E may,

curved wires 9 serve as set-screws to hold the ment,including the casting B, may be changed in inclination", or turned 'forward or backward at will, according to the direction of the sun or wind. Any change in the inclination of the casting R tends to draw in one of the threaded ends 19, and, to an exactly'corresponding extent, liberate the other.

The arching support formed by the bent wires 19 presents a-tasty appearance,'and gives great strength and firmness to the construction with a small amount of material.

A thumb-nut, Q, provided on one side, may

- be employed to tighten the contact and increase the friction between the wire 1) and the casting R if it should, by long use, tend to turn one or more screws, or like device, would, in consequence of thewrenching strain caused bythe passage of the vehicle overrough places, be liable to be torn from its fastenin gs.

I claim as my invention- 1. The castings E, receiving and connecting the axle B, perch O, and spring m, as herein specified.

2. In combination with the bodyA and axles B, the spiral springs m, connected to. castings above and below by screw-threads corresponding therewith, substantially as herein specified.

3. The bent supports 1), in combination with the parasolT and two sockets, P, fixed in the opposite sides of the body A, as herein specified.

4. The casting R, connecting the shank t of the parasol with the side supports 1), the connections being formed by screw-threads, arranged to serve as herein specified.

In testimony whereof I have hereunto set my hand this 16th day of September, 1872,in the presence of two subscribing witnesses.

SAMUEL MOINTIRE.
