Letters Patent No. 113,705, dated April 11, 1871.

IMPROVEMENT IN CA'RRIAGES.

The Schedule referred to in these Letters Patent and making past of the lame.

To al'l whom lit may concern:

Be it known that i, CHAUNCEY THoMas, of Boston, in the county of' Suffolk and State of Massachusetts, have invented Improvements in Oarriages; and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a descriptiono my invention suicient to enable those skilled in the artvtopractice My invention relates to the construction and arrangement of the carriage-body and spring-supporting mechanism .of four-wheeled vehicles, the invention as relates to the body having particular reference to the manner of uniting `a metal body toA a sunken wood bottom, and as relates to the springs, having particular reference to a provision for end movement of the rear parts of the springs of side-spring carriages.

The invention consists in mounting. or supporting a carriage or wagon-body upon side springs, the rear end of' each vot which is provided with au eye or runner that rests and slides upon a short rod, mounted in a stand, iixed upon the top'of the rear axle or axle-bed. Y

The invention also consists in a sheet-metal ,body,

having a sunken wood bottom united to the bottom l of the body sides by a anged connecting-plate, the upper flange of which extends over and rests upon an inwardly-turned iiange at the bottom of the body sides, (the edge of the plate-flange abutting against the inner surface of' the body sides,) and the bottom flange of which extends inward and forms a support for thewagon-bottom, the flange-plate being inclined or curved between its top and bottom flanges.

The invention further consists in u-prights for supporting the cross pieces for the seat, fastened to the body by metal-strap pieces, which are riveted upon the inner surfaces of the base-plate and to the inner surfaces of'i the uprights, so that the seat is supported without extending fastenings through the metal body sides,

The invention further consists in the manner `of making the corners of the iiange-plate where the end and side pieces are joined.

The drawing represents a carriage-body and springs embodying my improvements.

A shows the body and springs in side elevation;

B is a section on the line x :1;

O is a plan of' the body and springs; and

D, a reversed plan of the body.

E F and Gr are detailsillustrating thc manner of forming the corners of the bottom sides.

H is a section (enlarged) showing the manner of` connecting the vertical .body sidesand the wood bot-' tom by the bottom side or flanged plate.

a denotes the body or body sides, preferably formed of one sheet of metal, bent to proper shape, or into boi: form, and having at the bottom of' each side an inwardly-turned lip or fiange, b.

c denotes the bottom, made of wood, and deepening from the ends toward the center to form ample leg and foot room.

d denotes the bottom sides or the metal flangeplate that connects and unites the body` sides a and bottom b. y

This bottoni side piece is composed of end pieces e and side pieces f, connected together to form one frame. At the top of`v this bottom side or frame, and all around it-,is an outwardly-projecting flange, g, the edge of which ts against the inner surface .of the hodysides, this flange resting directly upon the body ila-nge or lip b, the two being fastened together by suitable rivets or bolts 11..

From this flange g the bottom side or Harige-plate inclines downinwardly, (being preferably made with a swelling-curved innersurfane,) and at its bottom it has another and inwardly-projeoting horizontal flange,

fi, extending all around its four sides, and upon this flange rests the bottom pieces b, cach piece b being chamf'ered or beveled at its edge, so that thenpper that the method of connection is such as to leave no open joints or prominences or uneven edges.

To efect a neat and substantial connection of the side and end pieces of the bottom side frame, I outout the abutting ends of the strips before bending them, as seen at E F, forming on one piece a tonguepiece, nl, that laps over and fits against and is riveted tothe inclined side of lthe other piece, the bottom edge of this tongue and the adjacent end of the flange of the same strip butting when' bent, the flange of the other piece extending under and being riveted to the first flange by a rivet, n.

The top fianges abut as seen at o, and the angle of the tongue 'm and the side piece from which it springs is in line with the end 12 of the incline behind it.

To obviat the necessity of bolt-ing through the body sides (which would mar the finish oi' the body) to secure the seat-supports, I place each vertical seatpost Ir against the inner surface-of the body side, as seen at B, and bolt them to metal-strap pieces s, which are bolted to and extend up from the bottom an eye-piece or runner, z, on the end of the spring.

Claims. Y

l. In combination with a met-al body, a, and wood bottom b, a connecting bottom side or frame, d, having a to'p ange, G, supported upon a flange or anges, b,

projecting inwardly from the bottom o` the body sides a, and a bottom ange, c', upon which the bottom strips arefsupported, substantially as shown and described.

2. In combination with the metal body' w, the seatposts placed against the inner surface of the opposite body sides, and riveted or bolted to vertical metalstrap pieces s, Whose lower ends are fastened to the bottom-sides frame d, substantially as shown and described.

of the bottom side pieces d, substantiallyas shown and described.

4. Side springs, tl1e rear ends of Which-have e'yepieces or runners z' sliding upon rods y, iixed in heads or Yplates x, on the rear axle or axle-bed, sub` stantially as shown and described.
