RUNNING-G EAR FOR CARRIAGES.

SPECIFICATION forming part of Letters Patent No. 746,710, dated December 9 3- Application filed September 22, 1903. Serial No. 114,182. (No model.)

clear, and exact description of the invention,

such-as will enable others skilled in the art to which it appertains to make and use the same, 7

reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in running-gear for carriages,

and especially in the provision of side bars.

and metallic springs in com biuation with parallel wooden spring-boards connecting the axles of the gear and intersecting springbars so arranged as to prevent swaying of a carriage-box supported upon the springs and securely bracing and holding the springs against severe strain.

Another object of the invention resides in the provision of a running-gear for carriages in which metallic side springs and barsv are employed in combination with parallel wooden spring boards or bars and so arranged that the latter are held slightly bowed for the purpose of acting slower thanfthe metallic springs connected thereto, whereby the vehicle will efiectually take up sudden jars as it passes over rough roads.

The invention relates, further, to various combinations of parts and arrangements of details of construction, which will be hereinafter more fully described and then specifically defined in the appended claims.

My invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings similar letters of reference indicate like parts in the several views, in which- Figure 1 is a top plan view of a runninggear, showing my improvement. Fig. 2 is a side elevation of the invention, parts being in section. Fig. 3 is a top plan view of a slight modification. Fig. 4 is a view of the modified form, parts being shown in section; and Fig. 5 is a detail view.

Reference now being bad to the details of the drawings by letter, A designates the front axle of a running-gear, and'B the rear axle, and O and O designate parallel spring-board bars, the rear ends of which are fastened in A cross-bar Gconnects the spring-bars C and C at their middle portions, and metallic spring-bars H and H intersecting each other at K, where they are held together by means of a clip K, have their forward ends secured by means of bolts h underneaththe central bar G, while their rear ends are fastened by any suitable means to the rear axle adjacent to the bearing portions or wheels, as shown. At locations where said bars pass underneath the wooden spring-bars O and G they are fastoned by suitable clips h. v.

N N designate metallic side springs the ends of which rest in the socket members F and have slight play therein. The socket members on the forward end of the gear rest upon and are secured to the bar D,which is fastoned to the front axle and to the fifth-wheel,

while the rear end of said springsN rest in socket members F, which are fastened by clips or suitable means to the rear axle of the gear. In order to prevent the rattling of the springs in their movement in said socket members, pieces of leather or other suitable material are preferably placed in the bottoms of the socketmembers and upon which the springs rest. Aside bar M is fastenedto each of the springs N by meansof the clips 0, which clips engage plates M, receiving the bars G, as shown clearly in Fig. 2 of the drawings. 1

Connecting the ends of the two side bars M are the metallic bars Q, to which the body of the carriage is adapted to be fastened. By having the bars Q fastened as shown t-he weight coming upon the box is equalized and the strain evenly divided upon the springs.

In Figs. 3 and ll have shown a slight modification in the construction of my runninggear, in which two cross-bars E and E are provided which are fastened to the wooden bars 0 and O at locations at short distances from the rear and front axles of the gear, and in this modification I have shown socket members F as mounted upon the projecting ends of the bars E and E to receive the ends of the side springs N N, thus throwing the entire Weight of the body of the vehicle upon the two spring-bars C and 0 instead of partially upon the axles, as shown in Figs. 1 and 2. In the construction shown in Figs. 3 and 4: I make a'longer gear than is possible in the construction shown in Fig. 1, which latter makes a shorter gear, as the ends of the side springs rest directly over the axle.

Bythe arrangement of the spring as shown and described it has been demonstrated that the swaying of the carriage, which is common with the ordinary spring-bars common in the art, is dispensed with, while the parts are securely braced against severe strains, and by the provision of the wooden spring bars, which are held bowed by means of the arrangement shown, they will act slower than the side metallic springs, whereby effectual means isprovided for taking up sudden jars incident to the running of the carriage over a rough road.

While I have shown and described a particular construction of bevel-carriage,itis understood that I may make alterations in the details of construction of the same, if desired, without in any Way departing from the spirit of the invention.

Having thus fully described my invention,

1. In arunning-gear for carriages, the combination with the axles thereof having springboards supported thereon, of a central crossbar fastened to the upper faces of said boards, apertured plates M mounted on the ends of said cross-bar which project beyond the outer edges of the springboards, metallic leafsprings and side bars fastened to said plates adjacent to the outer edges of said boards, cross-pieces Q connecting the ends of said side bars, and spring brace-bars secured at their forward ends to said central cross-bar, intersecting each other, and secured at their rear ends to said axle, as set forth.

2. In a running-gear for carriages,the combination with the front and rear axles thereof, of a bolster secured to the forward axle, spring-boards fastened at their rear ends to the rear-axle of the gear and their forward ends secured to said bolster, flanged socket members secured upon the ends of said bolster and upon the rear axle adjacent to the outer edges of said spring-boards, a central cross-bar G fastened to the spring-boards, apertured plates mounted upon the projecting ends of said cross-bar, leaf-springs and side bars fastened to said apertured plates, the ends of said leaf-springs resting in said socket members and having a slight longitudinal play guided by the flanges of said members, cross-pieces connecting the ends of said side bars, intersecting brace spring-bars fastenedat their forward ends to said central cross-bar and their rear ends to the rear axle of the gear, as shown and described.

In testimony whereof I affix my signature in the presence of two witnesses.

PHILIP KLETT.
