IMPROVEMENT IN GEARlNG AFORl WAGNS.

The Schedule referred 1:o n these Letters Patent and making part ef the samev i,

the drawing Iwhich accompanies and forms part of this specification,is a description of my invention suicient to enable those skilled in the artto practice it. u My present invention is for improvements upon the buggy-gearing patented to .Ihe'iirpatent No.-102,905, dated May 10,1870, and antedated January 13,1870.

Myimprovementsconsist;V

`4:-,' 4 First, in connecting together by a rigid rod the two fpivoted links upon the cli psemployed on the hind axle, vso-that, when, the weight .is upon' one spring, both springs, by reason of the connectngfrod, shall be 4causedto work together; thus preventing the roll.

Also, in constructing the steel axle with an inverted V-shapcd` space'or cavity lengthwise of the same, on

its under side, thus materiallyligl'itening the axle and saving stock, while leaving the axle in the best lfori for strength.

Also, in combining with compress a rubber pad placed between the bottom of the wheel and the under lugon the brace, and Apre vent rattling'.

Also, in the employment of braces running from the bolster, and preferably bolted to the fth-wheel,over which they pass, and firmly secured to the reaches',

Also, incertain details, hereinafter mentioned. Inthe drawing- Eigure 1 represents a side view of my improvements,

the springs being shown in two positions, to show the j action of my improved clip connection;

The rod which connects together the swinging links i on the hind axle is shown at G, the clips being seen at and the links at Il a fifth-wheel lugs atiits middle, which, in conjunction with a lug and` bolts' upon the brace connecting it with the bolster, serve to' DD arethe reaches connecting the bolster and hind i "To al@ whom 'it may concern: l

Be it -known that I, JOHN B. Aucun, of Pough- "keepsie', in'the county of rDutchess and State' of vNew f York, have invented certain Improvements inGear- -ing for Buggiesand other vehicles; and I do hereby declare that the following, taken in connection with The rod G is turned down at each end, to pass through the eyes of the links and through the clips, and is threaded at each extreme end','to receive a nut, g, This rod` turns in its bearings in the clips, the links having square or equivalent openings in their inner eyes, to receive a'correspondinglyfshaped portion of the rod. This insures a positive rocking of the rod upon its axis whenever either link is swung 'forward or back bythe action'of its own spring, and' positivelycompels (through the agency of the rod) the simultaneous and equal movement, and with positiveness, of both the links, and, as a consequence, an equal action of both springs of the vehicle, even'though all l the=weight may be upon onel side. In short, one spring cannot act without foreingtheA same action upon the 'otherpand hence, the weight is brought to bear upon both'ends of the axle. Anything like a roll is prevented, andv there is no' undue ystraining or contorting "of thesprings', axle, `or any other parts.

` Instead ofliaving` the connecting-rod serve also as theaxisfor the swinginglinks,-it may be made sepa- `rate ly,a`nd' connect the links at a point above their ,certelsof motion.4 I prefer, however, the construction shown, as it condnces to greater strength and seb curity, and certainty of action.VV

Instead f makingv theaxle hat or square at the bottom,` as describedfin my above-named patent,jI

'formi-t on its under'side'gas shown at h in the draw# weight' and costof the metal, and inasmuch as the axle is still left of suicient vertical thickness to withstand fall the requirements of au axle, and is less clumsy, is found to be a great advantage.- The form given to the cut-away part impart-s to the axle the' properties and strength of the arch, and it is actually lessliable to break, and can better withstand and resist severe shocks than if made without the groove. This groove need not necessarily be made angular Vin cross-section, but may be in the form of a gothic, or of a 'true arch, the same general principle existing in either form, and the same advantages owing therefrom, for the purpose intended. c

The space in the groove admits of thc insertion, if desired, of a correspondingly-shaped piece or fillet of wood, to form a bed or bottom for the axle, and the same will be, when used, securely held to place against side, and the lower part l is made in one continuous piece, of about the same lengt-h as the upper part or circle, and continuously convex on its upper side;

.it almost entirely from the jars and jerks to which it is subjected under other known constructions, and from the risk of damage or accident likelyto result' vtherefrom,l and insures, also, an equal distribution of the wear throughout -the whole of the concaveor grooved surface, and causes much less wear than it" the convex portion was made in two short segments like brackets, and placed' distant from each other on opposite sides of the center ofthe holster, as has been heretofore practiced. By my construction, also, each circle steadies the other, and braces it most effectively; and, at the same time, I' have all the advantage due to the prevention of any accumulation of 'dustbetween the circles, as it must drop away by its own gravity', because of the double inclined or arch form of the upperl side ot' the lower circle which prevents any dirt or dust from vremaining thereon.

Lugs m, upon the upper partil at its center, are connected with a similar lug, n, upon the piece or bracket, K,which extends from beneath the king-bolt, and bolts and nuts, o p, as secu, serve to clamp together these lugs and the interposed lower part l, .ot the tifth-whcel, so as, nevertheless, to permit the latter to move as may be required.

Between the lower lug n and the part l I placca rubber or equivalent pad, q, which, by means of the nuts upon the bolts, may be screwed as tightly as may be found desirable, in order to avoid direct contact 'of the parts l and n, and thus prevent their rattling, the

same compression which ei'ects this serving, at the same time, to keepin sufficiently close contact'the concave and convex parts of the wheel, which vthus cannot rattle. l

Rigidly connected with, and forming one with the bolster G, I4 employ two braces, F F, extending therefrom to the reaches D D,to which they are firmly secured, as seen. Thesc braces pass directly across the stationary part of the fifth-wheel, and may be fastcned also to it','thus adding to their irmness and eniciency, and each bracing the other.

In tig. 2 the springs conceal the reaches D D, and one onlyis visible vin fig. 1

The front axle is shown of form similar to the back one,'and may, if. desired, have a similar wooden bed. The bolsteralso may be' made of similar arched form on its under side, and for the same. purpose The dotted lines in g. 1 show thel positions of the buggy-body, springs,'andpivoted links, under the action of any weight, the springs and links on both sides ot the carriage descendingequally, whether the weight be on one side or not.

1.- The herein-described method of equalizing the vaction of springs of vehicles, anddistribnting the Weightl of the load.

2. The combination of the pivote'd links with a rod ,connecting the same, the rod compelling both links to move inunison, as land for the purpose described.

. 3. An axle or bolster having its under side cut away orarched, as and for the purposes described. 4. In combination with an axle or bolster having s'uch an under side, a wooden bed, arched or' A-shaped on its upper side, to adapt-it thereto'. f

A 5. A fifth wheel, constructed as shown and dcscribed, that is, with a concave under side on its up-k per part or circle, andwith a continuous convex upperside on its lower part oi' circle, the two having an unbroken or continuons bearing-surface, one upon the other, and operating together, as and for the purpose -sct forth.
