ICHI'LDS CARRIAGE.
EPECIFICATION forming part of Letters Patent No. 351,818, dated November 2, 1886.
Application filed January 29, 11-386. Serial No. 190,150. (No model.) I
and elegant appearance, that in its construction combines simplicity, strength, and durability; and for that purpose my invention principally consists in connecting the axles by side reaches formed of metal tubing; also, in forming the handle and its reaches of a single piece of metal tubing,of which the axle-reaches may be an elongation and solid therewith; also, in the device of connecting ,the axles to these reaches by sleeve-couplings, and, finally,in the peculiar construction of the body-springs and in the devices for securing them to the sleevecouplings, all as hereinafter will be more fullydescribed and specifically claimed.
In the accompanying drawings, Figures 1 and 2 represent a side elevation and a plan view of the running-gear; Figs. 3 and 4, a longitudinal section and a plan view of the sleeve for coupling the axle and leaf-spring to one of the reaches, and Fig. 5 a perspective viewof the twin wire spring as secured to. an axle coupling-sleeve.
Corresponding letters in the several figures of the drawings designate likeparts.
A A denote the axle-reaches; B B, the hand1e-reaehes,'and O the handle proper, all of which consist of a single bar of metal tubing bent to the required shape, so as to be one continuous piece.
Over the axle-reaches A A are passed malleable-iron sleeves D and E, each secured in.
proper position bya rivet passed through a hole in such sleeve and tubing. Each such.
sleeve D and E has a hub,-b,-cast to its bottom side, through which hubs are passed the axles F and G, and are rigidly secured therein. As
will be readily seen, the reaches thus formed solid with the handle and connected with the axles in the manner described will compose a very stiff and rigid frame that requires no bracing of any kind, and metal tubing being very light relative to its strength this metal frame will weigh less than running-gears for such carriages heretofore made of wood.
Although I prefer to form the axle and handle reaches of a continuous single piece of tubing with the handle, yet it is not essential for my purpose, since I can make the axle-reaches separate pieces rigidly coupled to the handlereaches by the sleeves E.
H is an 'S-shaped leaf-spring attached to sleeve D by providing one end of such sleex e with a loop, l2, through which the end of such spring is passed, and is'secured in position by a screw-bolt, (2, passed through a hole in the spring, sleeve, and tubing, and tightened by nut e.
I is a double spring formed continuous of a single piece of wire, in a manner that each side consists of two coils, f and g, each such coil of about one and One-half turn, and both coils separated by an inclined 'or nearly horb zontal connection, 0, with the upper continuation of both springs connected by cross por tion 2', that forms the coupling-hinge to the carriage-body, and with the lower horizontally-extending ends of both springs being rectangular] y bent toward each other. For attaching this spring Ito sleeve E, I cast upon one end of such sleeve a tubular cross-bar, m, for inserting therein from both ends the rectangularly-bent ends j of the double spring, and upon the opposite end of such sleeve E, I cast a cross-bar, n,'having notched-outends for receiving the shanks of the spring ends, and for securing them therein by clinching the notch-prongs of bar a over the spring-wire.
Instead of applying springs H to one end and springs I to the other end of the runninggear, either style of springs may be used entirely.
The handle C may be covered with any kind of material that is a non-conductorof heat, as shown in dotted lines.
Although having described herein tubular metal bars, I may use metal bars of other seetional shapes that will be applicable for my purposes, andtherefore I do not wish to be restricted to the'use of such tubular bars.
axle-reaches, of suitable springs and a carriage-body, the springs secured to thebody and r 5 the sleeves, as set forth.
4. The combination, with an axle and a sleeve, E, the latter provided with tube m and notched barn, of a spring and a carriage-body, as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
OTTO UNZICKER.
