OSCILLATING GEAR FOR WAGONS.

SPECIFICATION formingpart of Letters Patent No. 247,365, dated September 20, 1881.

Application filed March 21, 1881.

To all whom it may concern Be it known that I, HORACE L. KINGSLEY, residing at Racine, in the county of Racine and State of \Visconsin, have invented a new and useful Improvement in Oscillating Gears for Platform Spring-Wagons, of which the following is a full description, reference being bad to the accompanying drawings, in which Figure 1 represents a plan; Fig.2, a side elevation; Fig. 3, a side view of the parts shown; Fig. 4, a side view of the parts shown; Fig. 5, a cross-section at line 00 of Fig. 3; Fig. 6, a cross-section at line y of Fig 1. Fig. 7 is an end view of the parts shown. Figs. 5 and 6 are enlarged.

It has been found desirable to use an oscillating gearin platform sprin g-wagon s, to which gear the wagon-bed is connected, the object being to prevent the twisting and straining of the gear and springs which must result when the gear is rigid, it the road is uneven or the wheels pass over obstructions.

My invention consists in a certain novel construction and combination of parts forming an oscillating gear.

In the drawings, A represents the central bar of a platform gear for a spring wagon, which gear may be made in any suitable manner and of proper length.

B is a circle, which is secured to the plat form-gear and receives the fifth-wheel, as usual.

0 is the fifth-wheel.

a is a friction-plate upon the bar A.

D is a longitudinal metal bar, the upper surface of which is convex.

b is the king-bolt plate, which is cast with the bar D. This bar D is secured to crosspieces E, which are secured to the fifth-wheel.

F is another cast bar, the under surface of which is concave to fit the upper surface of .the bar D.

G is a short bar permanently secured to the cross-bars H, which are riveted or bolted to the metal bar F. These bars H support the wagon-bed. The bars G and F both have a central hole large enough for the head of the king-bolt I to pass through, as seen in Fig. 6. U The bar F is hinged to the bar D by means of the loops or clips 0, which pass through holes Model.)

(I in the bar D, and up through the bars F and G, to which these loops 0 are riveted. In use the concave lower edge of the bar F rests in the convexity in the upper edge of the bar D, and is held there by the loops 0; but the bar F can rock upon the bar D, keeping the wagonbed practically level, although the wheels pass over obstructions or over an uneven roadway, thus taking the strain off from the springs and gear.

I have not shown the platform upon which the oscillating gear is placed, nor the springs which support the platform, but they can be made in any known suitable manner.

As shown, the bar has a groove extending its whole length, in which F rests. This isnot essential, but I think such the best construction.

The desired oscillating movement could be obtained by making the lower bar, D, concave on top, and the upper bar, F, correspondingly convex; but I prefer the construction first described.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

1. In an oscillating gear for platform springwagous, the center piece, D, in combination with the bar F, both formed and connected together substantially as described, whereby one can rock upon the other, substantially as and for the purpose specified.

2. In oscillating gear for platform-wagons, cross-bar D, formed with king-bolt plate I) and with a convex upper surface, and the recessed or concave bar F, carrying the supports of the wagon -bed, substantially as shown and described, combined for operation as set forth.

3. The bars G, H, and F, connected to form a support for the wagon-bed, the bar D hung on the king bolt, and the clips 0 connecting the bars F D, all substantially as shown and described, and combined to form an oscillating gear.

HORACE L. KINGSLEY.
