CARRIAG E-G EAR.

SPECIFICATION forming part of Letters Patent No. 416,436, dated December 3,1889.

Application filed anuary 21, 1889. Serial No. 297,064. (No model.)

To all whom it may concern.-

Be it known that l, \VILLIAM BOUGHTON, of

Mansfield, Richland county, State of Ohio,

have invented certain Improvements in Carriage-Gear, of which the following, taken in connection with the accompanying drawings, is a specification.

In the accompanying drawings, Figure 1 is a plan View of a mechanism embodying this invention. Fig. 2 is an elevation of a vertical central section on line 2 2 of Fig. 1. Fig. 3 is a perspective view representing the bottom face of the top member of the fifth-wheel, and Fig. 4 is a similar view representing the top face of the bottom member of the fifthwheel. Figs. 5, 6, 7, and 8 represent parts of the mechanism detached, and will be further de scribed and identified hereinafter.

The top member A of the fiftlrwheel is provided with a V-shapedgroove a. in the bottom face of its outer rim,which is adapted to receive a V-shaped rib b on the top face of the outer rim of the bottom member E of said fifth-Wheel. (See Figs. 3 and 4:.) Said members are further provided with central hubs d 6, respectively. Said hubs are provided with an opening to receive the king-bolt B. (See Fig. 2.) The contiguous faces of said hubs bear upon each other to form a support at the center of the fifth-Wheel.

The hub d is provided with a downwardlyprojecting lip f on the outer circumference of the hub, whereby is formed a chamber in the hub to receive the hub e, as shown in Fig. 2. The lip fis by this arrangement allowed to pass over and bear upon the periphery of the hub 6, whereby is formed a bearing intermediate the central journal (the king-bolt) of the fifth-wheel and the outer circumferential bearings thereof, whereby the lateral strain incident to the turning of the fifth-wheel is withheld from the central shaft or king-bolt Secured to the reach H is a reach-iron K, that extends upward and forward to the head block G, as shown in Fig. 2. Said iron is represented in perspective by Fig. 6 of the drawings. It is provided with a suitable opening for the king-bolt, and is chambered out to receive the central hub of fifth-wheel, as shown in Fig. 2. It is secured to the reach H and obvious fastening devices.

The king-'boltis represented in perspective by Fig. 7 of the drawings. On its top end is a clip adapted to pass over the carriagespring, to which it is secured by a bolt 72, as shown. It extends downwardly on the rear side of the head-block, passing first through the reach-iron K, next through the hubs d 6, next through a bottom axle-iron N, and then through the bottom reach-iron M, and is socured by a nut on its bottom end, all as represented in Fig. 2.

The axle-iron M is represented in perspective by Fig. 8 of the drawings. Said iron has on its end face a bearing-surface 4., also a V- shaped rib 5 and a central conical projection 6. The rib 5 and projection, 6 are made to enter the counter formations'in the bottom reach-iron M, while the surface 4 bears upon the contiguous face of the reach-iron M. The king-bolt passes down through said iron N cent-rally, as shown in Fig. 2, and on its bottom end is a nut that turns upward against the bottom face of reach-iron M, whereby the parts are held firmly together. The bottom axle is supported by this arrangement on the bottom reach-iron M through the intermediate aXle-iron N, and turns about the king-bolt as a pivot-journal, to which end the said bolt is made to pass centrally through said iron N and the hub 6. Lateral strain incident to the turning of the axle and fifth-wheel is withheld from the king-bolt by the above-described hub formation of the fifth-Wheel, and still further by the axle-iron N being socketed to turn in the bottom reach-iron M, as described, and provided with an end formationto co-operate with the reach-iron in resisting lateral strain. This feature of my invention I consider of great importance. It prevents the cramping and consequent cutting and twisting of the king-bolt. It keeps the axle from tipping or tilting, and consequently from rattling when the parts become Worn, and fa cilitates the turning operation by reason of the joint formed between the axle-iron N and the bottom reach-iron M.

I have described the iron N as having a bottom facial formation composed of a beart-he head-block G by suitable bolts or other ing-surface 4, an annular rib 5, and a conical projection 6, these parts being socketed into a counter formation arranged in the bottom reach-iron, whereby a duplicate fifth-wheel is formed intermediate the axle and the bottom reach-iron. The formation I have described is what I consider the most advisable, although I am aware that modifications thereof maybe employed without departing from the spirit of my invention.

It will be evident that in use, the bearingfaces of the central hubs e (I will become worn, and that by reason of wear incident to the parts a l) f 4: 5 G the said parts will in time become loosened and more or less operated relatively to each other, so that it becomes desirable to take up the said parts and prevent rattling noises incident thereto when loosened. To this end the plate N is adjustably secured to the axle S. The adjustment is obtained by causing the attaching bolts 7 S to pass through slotted openings 9 10 of the plate N. The bolts are secured in the axle S and hold the plate N by clamping the same to the axle by means ofla nut on the outer end of the bolts.

To obtain a vertical adjustment of the plate N it is only necessary to turn backward the said nuts, whereupon the plate may be moved vertically to a position desired, whereupon the nuts are again tightened to secure and firmly hold the plate to the axle S. The plate N is beveled from the top downward, whereby any downward settling movement of the axle wedges the axle and its supporting-iron N more securely. The top reach-iron K being chambered out to receive the hubs c (I, and being a separate iron, enables the builder to adjust it to the desired height relatively to the reach H and head-block G. The bottom reach-iron M has its forward end bent upward through an opening in the top member of fifth-wheel, and on the end thereof is a nut, whereby the position of the fifth-wheel is maintained substantially as shown in Fig. 2. The rear end of said reach-iron M engages with the hind drop reach-iron T. The engagement is made by setting the end of the iron M into a trough formed in the iron T, whereby is formed a splice-joint adapted to resist lateral strain. Said irons are secured to the reach H by means of bolts, as shown in Fig. 2. 011 the top of the reach is a strengthening-bar \V, which is held by the same bolts that hold the irons M T, and which co-operates with said irons to strengthen the reach, and to that end said iron has its rear end milled into the iron T, as shown in Fig. 2. The iron T is provided at its upwardly-turned rear end with a horizontal plate adapted to receive the rear axle-bar and clip-ties. It also has an upwardly-extending spur 12, that bears on the front of said axlebar, and is bolted thereto, so as to give strength and support to the same.

Having thus described my invention, I claim 1. In combination, in a carriage-gear, the axle, the lower member of the fifth-wheel supported thereon, the head-block having the other member, the lower reach-bar extending beneath the axle to the front and connected with the upper member A of the fifth-wheel, said reach affording a bearing for the axle, and the king-bolt extending from the lower reach and havinga tu r11 ed-over en d connected with the head block, substantially as described.

2. In a carriage-gear, in combination with an axle, as S, and reach-iron M, the intermediate plate IT, adjustably secured to the axle and bearing its bottom end on the reachiron, and a king-bolt support-ed from above and extended downwardly through the plate N and reach-iron, substantially as described.

In a carriage-gear, in combination with an axle, as S, the plate N and reach-iron M, and king-bolt, as B, supported from above and extended downwardly through plate N and reach-iron M, and the bottom end of said plate N being socketed into the reach-iron, substantially as and for the purposes described.

1'. In a carriage-gear, the king-bolt B, having its top end formed wih a hooked clip to embrace the carriage-spring, and a downwardly-extendingshaft having on its bottom end a screw-thread and nut, substantially as described.

5. In a carriage-gear, the axle, the headblock, the two members A E, the king-bolt, the lower reach, and the plate N, secured to the axle, said plate having a conical bearing end in a socket ot' the reach, substantially as described.

6. In a carriage-gear, the coi'nbination, with a reach-bar, as II, a head-block, as G, and a king-bolt, as B, of an axle, as S, said axle being pivotally connected with the king-bolt by an intermediate plate, as E, adapted to surround the king-bolt and interlock with a plate, as A, on the head-block, so as to relieve the king-bolt from lateral strain, as set forth, and also by an intermediate plate, as N, adapted to surround the king-bolt and bear downwardly on a reach-iron, as M, and having its end face socketed or stepped into the reach-iron M, whereby lateral strain is further obviated and the axle prevented from tipping, substantially as described.
