VEHICLE.

SPECIFICATION forming part of Letters Patent No. 242,816, dated May 31, 1881.

I Application tiled February 19, 1881. (No model.)

To all whom it may concern Be it known that I, PETER I-InRDIo, of the city of Philadelphia, in the State of Penusyl- Vania, have invented certain new and useful Improvements in Vehicles, ot' which the following is a specification.

Myinvention relates to improvements in vehicles of the class having cranked rear axles, and especially pertains to the connections between the frontend rear axles and to the springs by which the body ot' a vehicle is connected with and supported upon the axles.

In Letters Patent of the United States granted to me April 20, 1880, No. 226,748, is shown a vehicle of the same class, generally considered, as that to which my present invention belongs. In accordance with the invention covered by my said patent a non-turning front axle-tree, provided at its ends with jointed axle-arms or turning stud-axles, is connected with a rear-cranked axle and maintained always parallel lherewith by means of a rigid braced reach.

My object now, mainly, is to dispense with the reach proper and to connect the front and rear axles by the vehicle bed or body and supporting and bracing springs, thus maintaining the axles in proper relative positions while avoiding injurious e'ects incident to the employment ot' a rigid reach or perch d ne chiefly to its unavoidable vibration, resulting in constant strains and in the loosening and wear of parts.

In accordance with my invention the rear main supporting-sprin gs are clipped or firmly mounted upon the cranked axle close to its upright portions or cranks, and are jointed, respectively, at their front ends, to the opposite ends of a cross bar or plate upon which the vehicle-bodyrests. Otherandlighterorweaker bracing-springs, which may be termed halfsprings,77 as they are ot' about half the length ot' the main supportin g-sprin gs, are rigidly connected at their rear ends, respectively, with the respective cranks of the axle, and at or near the tops or upper ends thereof, while at their front ends these tension and thrust or two- Wayacting brace-sprin gs connect by joints with the tops of angle-trusses or brackets at points respectively above and about in the vertical plan es ofthe respective jointed front ends ot' the main supporting-springs. Instead of bracing springs, braces consisting of bars jointed at their ends to the. trusses and axlecranks maybe employed. A second cross-bar for the body to rest upon is secured in front of' and parallel with that one to which the fronts ot' the supporting-springs are jointed. The trusses orbrackets connectthese two crossbars firmly, or, instead of two cross-bars, one broad barorplatemightbeemployed. Acrossspring connects the rear ends of the two main springs, orinstead of this cross-sprin g a simple bar may have the rear ends of the two main springs jointed to its ends. A supporting-piece on top ot' the cross-spring serves to connect with the vehicle body or bed at the rear in the usual way. rlhe vehicle-body is supported upon the front axle, and the front axle-tree or axle proper is connected with the body and rear axle by means of four springs or half-springs arranged in pairs, one pair serving as bracesprings, which arelocated above the other pair, or jointed bar-braces may be substituted for the pair of spring-braces. The lower springs are respectively rigidly-connected, at their rear ends, to or near the opposite ends of the beforementioned front cross-bar, and at their front ends are respectively jointed to the axle-tree near its opposite ends. The upper or bracing springs are jointed to the axle above the jointed connections therewith of the lower springs, and at their rear ends each of these bracing-springs is rml y and rigidly connected with the vehiclebody. The front and the rear bracing-springs are located, respectively, in or about in the respective horizontal planes of the axle-arms or wheel-journals of the front and rear axles, and the draft-strain is thus brought centrally, or nearly so, upon the Wheels of the vehicle.

My invention also relates to minor improvements in various parts. i

The subject-matter claimed will hereinafter be designated, after rst fully describing my improvements in connection with the accompanying drawings, in which are shown those parts of a suitable vehiclefor instance, the Herdic 7 coach, represented in my beforereferred-to patent, No. 226,748-which are deemed sufficient for illustrating and describing my present invention as preferably applied.

Figure 1 is a side elevation with the wheels IOO partially shown in dotted lines. Fig. 2 is a view in perspective of the axles, springs, &e., or the running-gear. Fig. 3 is a front elevation, showing the i'ront axle-tree and its independentl y mounted stud-axles or short-turning axle-arms. Fig. 4 is an elevation of parts shown in Fig. 3, the draft attachment heilig in part represented. Fig. 5 is a view showing the front axle-tree and the vibrating draft-bar in section with the vibra-tin g strap-bracket or device for attaching the shafts in elevation. Fig. Gis a plan view of the vibrating strapbraeket for attachment of the shafts.

The rear cranked axle, A, is made of any suitable material, has diagonal struts or braces a (t, for strengthening its upwardlyprojecting ends or cranks A' A', and has main supporting-springs 1? I3, mounted upon it near its cranks, and connected by joints at their rear ends with athird or cross spring, B', asin my before-recited patent. The front ends ot' the springs B B are jointed,respectively, to the opposite ends of a cross-bar, C, to which the vehicle bed or bodyD is suitably fastened. Lugs b b, on the under side ot' the bar O, serve to joint the springs to this bar. In advance of the bar C there is a second cross-bar, C', to which the bodyD is to be secured. Obviously a single broad metallic plate or wooden bar might be used instead ot' the two bars C C', or any suitable provision be made for connecting the body and the springs.

Suitable brackets or angle trusses E E, firmly secured at their bases to both et' the cross-bars C C', serve alone, or, by preference, in connection with braces d d, on the under sides of the cross-bars, to hold these bars rigidly in proper relative position or parallel with each other. Each bracket E and its adjacent brace-bar d may be made iu one piece, the ends of the bracket-base and the ends of the brace-bar joining in loop form to adapt the combined bracket and brace to be slipped on the ends ofthe cross-bars,to be secured in obvious way.

Suitable braces, in thisinstanee sp1-in g-braees or half-springs F F, are respectively jointed attheir front ends to or near the tops ofthe respective brackets E E, and each of these springs F is rigidly secured at its rear end to its respective crank or upright portion A of the rear axle, near its axle-arm or journalf. The jointed connections of the i'ront ends of the brace-springs, with the trusses or anglebrackets, are made by lugs c c and pins or bolts.

The bracketsupporting trame, formed by the cross-bars C C, is connected with the front axle-tree or axle proper, H, by springs G G extending from the front portion or bar, C', of the bracket-frame to lugs or ears on the axletree, to which the front ends of the springs are jointed. These lugs It h are shown as formed with the' metallic portion of the axletree on its under side and near its ends. Each spring Gis rigidlyconnected atits rearendlwith the bracket-frame. Two arms, g g, rigidly connected with and projecting from the front crossbar, G, of the bracket-supporting frame, one arm neareitherend of said cross-bar, is shown as provided for attaching the rear ends ot' the springs.

Above each spring G is a bracing-spring, I. Each of these springs I I is jointed at its front end to the axle-tree H, while at its rear end it is rigidly attached to the vehicle-body, or it might be both to the vehicle-body and crossbar C. By reference to Fig. 1 of the drawings it will be seen that the brace-spriligs I I connect by bolts at their rear ends with the front ofthe vehicle-body low down, and with a crossbar, I', beneath the seat for the driver or in advance ot' the body proper ofthe vehicle. The lugs 7i h by which the fronts ot' the bracing springs I I are pin-jointed to the axle are shown as formed upon the upper metallic portion of the axletree. Intermediate the upper and lower metallic portions or bars, J J, there is secured a wooden bar, J 2. This axle-tree may, however, be composed ot` any suitable lnaterial or materials instead ot' heilig constructed ex actly as above described. The springs I I, it will be seen, connect with the axle-tree at about the level of the axle arms or journals k 7.1 for the front wheels.

The axle-arms L k are formed with or properly attached to turning-posts K K. These posts, instead ot' being tubular or sleeve-like, asin my Patent No. 226,748, are, by preference, made solid and provided with rounded or semicircular top and bottom bosses, l l, from which project short threaded studs Z l', and the turning-posts, instead of being supported at their lower ends directly upon the axle-tree or axle proper, are supported at both ends in diagonal struts or braces jj', arranged in pairs and projecting above and below the plane of the axletree. the metallic bars J J. At their ends the struts have rounded bearin g seats or sockets to receive the bosses on the turning-posts, and the threaded studs l l of the posts pass through openings made through the tops and bottoms ot' the strut ends and colnmunicatin g with the centers of the sockets or seats therein. Nuts upon the threaded ends ofthe studs l l serve to hold the parts together.

A vibrating draft-attachment bar, M, is pivoted at its ends to the front ends of the forwardly-projecting braces N Nl N N', which are formed with or rigidly attached to the turningposts K K. A vibrating bracket or forked strap is pivoted to the axle-tree H and to a lugged clip, P, thereon, by a bolt passing through the axle and through the lug p. at the top ofthe clip, as well as through the lugs p' p', which embrace the axle and enable the one bolt O and nuts o o on its threaded ends to secure the lugged clip in place and pivot the bracket thereto. This bracket Q is provided with three arms or forks, two ot' them, q q, being horizontal and pivoted at their joined rear ends on top of the lagged clip, while the other arm, q', is diagonal, extending back downward- ICO These struts are formed by the ends of A ISO ly and terminating at its rear end beneath the axle-tree, where it is pivoted between the axle andthe bottom lug, p', of the clip P. At front the bracket is bolted to the bar M, and has perforated open lugs or sockets m m, into which engaging-lugs of shafts fit loosely and are pivoted, so as to be free to vibrate vertically, by means of one through bolt or pin or two bolts, one for each lug, as will readily be understood. The shafts, it will be seen, are in this way prevented from swaying horizontally except with the movements of the sway-bar M in turning the vehicle, and they may quickly be attached or removed. A tongue-provided with lugs to engage the socket-lugs m ai may be employed instead of shafts when desirable.

Instead of constructing the front axletree and its struts preciselyas above described, and as in part represented by dotted lines in F10'. 3, theI parts maybe modified somewhat, as, for instance, by making the struts j j j j' longer and the axle-tree correspondingly shorter, as represented by full lines in said ligure. In this way the turning-posts K K may be adjusted in place by springing apart the struts, if it be deemed desirable to so insert them, and the axle-tree and struts may be made wholly of steel or of iron, if preferred. Tubular turningposts and through-bolts may be employed in connection with the doubly-strutted axle-trees, as will readily be understood by referring to my before-mentioned patent.

Details of construction and arrangement of parts may be modified in various ways without departure from my invention. For instance, the springs may be altered in forni, the springs G G be extended back by shanks or arms beneath the cross-bar C and secured to it as well as to the bar C', the cross-bar arms g g dispensed with, and the springs I I connected with the truss-frame or cross-bar C' by means ot' suitable brackets, instead of being fastened at theirrear ends in the manner shown.

When suitable bar or rod braces are eniployed' in lieu of the springs F F and I I, such braces would be jointed in place at both ends, and would, as will readily be understood, occupy the saine or substantially the same positions in which the preferably-em ployed spring braces are shown by the drawings. Whether springs or bars are employed the braces have the same functions to perform.

I do not broadly claim spring-reaches or yielding or self-compensating connections between the front and rear axles of vehicles; neither do I broadly claim bracing cranked axles, for I am aware that one-way iexible braces, such as cords or straps extending from the axle-cranks forward to the vehicle-body, have been employed. Such braces are unlike mine, which, instead of acting merely as tensional braces, are both tensional and thrusting braces.

I claim as of my own inventionl. The combination of the cranked axle,the main supporting-springs secured thereto, and the two-way acting or teusional and thrusting braces located above said sp1-ings and having connection with the axle-cranks and the vehicle-body, substantially as andfor the purpose hereinbefore set forth.
