SPECIFICATION forming part of Letters Patent No. 288,707, dated November 20, 1883.
Application filed August 18, 1883. (No model.)
.ToaZZ whom, it may concern:
Be it known that I, RICHARD J AOKS, a citizen of the United States, residing in Meadow Valley, county of Plumas, State of California, have made and invented certain new and use ful Improvements in WVagon-Reach Couplings, of which the following is a full, clear, and exact specification, the accompanying drawings forming a part thereof. 7 I
Myinvention relates to a novel coupling for connecting reach to axle inrunning-gear of wagons. The coupling partakes of the character of a universal joint. It is constructed and provided for the purpose of permitting free swing and independent movement within limits of the reach and axle, while at the same time it affords a strong and effective fastening for these parts together. I
The manner in which I proceed to produce, construct, and apply my said invention is as follows, in the drawings referred to Figure 1 being a perspective View of the front axle, bolster, and reach; Fig. 2, a top view ofsame; Fig. 3, a longitudinal section in elevation.
A represents the front axle of a wagon, and B is the reach connecting the front and rear axles.
The hounds are seen at c c, and the sway-bar at d.
E is a stirrup-plate bent into semicircular form, and having two screw-threaded ends, 6

the circular part. They are also of equal length, and extend backward from the broad The plate E is secured to the back of the axle, at the point'wherethe reach is to be attached, by passing the ends 0 0 through holes in the axle, or through apertures between the axle andthe bolster-bar f, that is clipped to the axle. A strong and secure fastening is insured by using plates 9 9 upon the front and rear, and then screwing down nuts h, and, if necessary, using This mode of fastening is seen in Figs. 1 and 2 of the drawings.
Over the end of the reach B is secured a strap-iron, H, having an eye, h, for a couplingbolt, I, to pass through The bend or loop of the stirrup E is slotted also for the passage of this bolt the slot being wide enough for free play of the bolt, and extending from side to side to give sufficient lateral movement as well. The head of the coupling-bolt is curved on the back face, so as to fit the curved bend or loop of the stirrup. This head consists of a convex 5 5 saddle-block, J ,with a square hole in the center, through which the shank of the bolt having corresponding form is inserted. In the rounded face are recesses j, to receive frictionrollers k k, that are placed in line, one above and the other below the bolt-shank. These rollers are employed to take the friction from the saddle-block. The bolt and saddle-block can be one structure; or they can be detached or separable parts, as I have represented in the drawings. In such construction the shank of the bolt will beheaded on the outside, and the face of the block that it bears against will be flat.
the reach and to the middle of the axle, respectively, the saddle-blockbeing slipped into place, with the coupling-bolt extending through the slot, before the part E is secured to the axle.
The two parts E H are secured to the end of The parts. of the coupling are then united by passing the end of the coupling-bolt through the eye in the part H, and screwing down a nut, Z, placed on the threaded end of the bolt. The strap H is fixed to the reach to give sufficient room between the head of the strap and the end of the reach for placing and removing this holding-nut.
A rubber spring or thick elastic washer, m, is interposed between the parts of the coupling,
and when they are drawn together by the coup- 8 5 'or jointed coupling in this manner, the rack and strain upon the running-gear of vwagons will be greatly reduced, and their durability and greater comfort and ease in riding as wellfg 5 are increased to a high degree beyond that which is attained in and by rigid connection of these parts.
Having thus fully described my invention,
what I claim, and desire to secure by Letters 10c Patent, is
1. A jointed or flexible reach-coupling for running-gear of Wagons, consisting of the parts. ,E, having means for fastening it to the axle, lo I E H, adapted to be fixed to the end of a reach of the saddle-block J ,with fricti0n-r011ers,and
and the middle of the axle, respectively, the the coupling-bolt I, for making attachment of c0up1ing-b01t I, saddle-block J, and spring m. i said saddle-block with the end of the reach.
2. The combination of the stirrup-plate E,
having the slot for the play of the bolt, the lnOHARD O saddle-block J the strap H, and the c0up1ing- XVitnesses: bolt I. LEWIS STARK,
3. The combination, with the stirrup-plate J M. CHAPMAN.
