WAGON RUNNING-GEAR.

srncrrrcnrron forming part of Letters retentive. 291,468, dated January 1, 1864.

Application filed April 28, 1883; (No model.) i

To all whom it may concern Be it known that I, Brennan CHAPMAN BLAonwnLL, a citizen-of the United States, and resident of Henderson, in the county of 5 Henderson and State of Kentucky, have invented certain new and useful Improvements in Wagons, of which the following is a specification.

My invention relates to wagons of that class in which the tongue is flexible that is, pivoted between the hounds, so as to allow it vertical oscillation upon said pivotas acontradistinction to wagons of another class having a stiff tongue, or where the tongue is 1 rigidly secured between the hounds, so as not to allow of the aforesaid oscillation with relation to the hounds. The object of my invention is to allow of pivoting the forward end of the reach to thercar end of the tongue, while providing for said oscillatory movement of the tongue, the feature of pivoting the reach and tongue togetherbeing known before this invention.

In the accompanying drawings, Figure 1 rep resents a longitudinal vertical section of the front part of a wagon, taken on the line 2 z of Fig. 2, and seen in the direction of arrow 1. Fig. 2 is atop view ofthe same. Fig. 3 is detail cross-section on the line a x of Figs. 1 and 2. Fig. 4 is a partial section of the bolster and sand-board,taken on the liner yof Fig. 2. Fig. 5 is a perspective view of a hinge-bolt for connecting the bolster and the sand-board. Fig. 6 is a rear view of the front portion of awagon, partly in section through the line yy, and illustrating the intended operation of my present invention when the wagon is tilted. Fig. 7 is a top view of the bolster with the hingebolt applied.

A designates the axle; B, the head-block or sand-board; O,the bolster; D, the tongue; E, the hounds, and ethe bolt connecting their rear ends; F, the reach. The tongue I) is pivoted between the forward ends of the bounds by a bolt, d, passing through the said forward ends and the tongue simultaneously. The forward ends of the hounds in front and rear of the pivot cl are connected together on the upper sides by cross-plates a a, the plate a being fiat 50 and straight and the forward plate, a, being raised or bail-shaped in the center above the tongue, so as to allow the forward end of the said tongue a free movement a sufficient distance upward. An opening is made in the center between the axle and the head-block, 5 5 through which opening the forward end of the reach projects in front of the axle, and is pivoted to the rear end of the tongue, a bolt, f, passing through the reach and through lugs h 71., which lugs are secured, respectively, to the lower and upper surfaces of the tongue; but the lug h is bent upward and then rearward, so that the distance between the two lugs h h at the point at which theloolt f is inserted through them is much greater than at 6 the point at which they are attached to the tongue, or in this case greater than the thickness of the tongue, thereby allowing the rear end of the tongue to be depressed and its forward end to be raised, as it needs be-for instance, in driving up hill-the bolt-plate a, forward of the pin (1, presenting no hinderance to such movement, while a movement of the forward end of the tongue too far downward,

or near to the ground, is prevented and 7 5 stopped by the straight plate a engaging with the upper surface of the tongue in the rear of the pivot. By the aforesaid construction of the coupling h hf the reach can be pivoted to the tongue when desired, while yet allowing the tongue to be oscillatednpon the pivot d to raise or lower its forward end.

I lay no claim to coupling tongue and reach together by means of lug and pin, but to the construction, in combination with the reach 8 5 and pivoted tongue, which allows of raising and lowering the latter.

In order to enable the bolster to retain a comparatively horizontal position during the tilting motion of the axle A, I have provided means-for making the bolster laterally oscillable upon that surface around the pivot of the sand-board upon which the bolster rests; For this purpose the hole in the bolster by which the latter is pivoted upon the pin 6., secured in the sand-board, is made widening upward toward the upper sides of the wagon, while the front and rear sides of the hole are parallel with each other, suitably to receive a metal thimble, c, of the aforesaid shape-or, that is I03 to say, of theshape of a flattened hollow truncated cone inverted, and placed so that the long axis of its base coincides or is parallel with the center line drawn through the length of the bolster, as shown in Figs. 2 and 4C. The lower opening in the thimble fits snugly, though not tightly, around the pivot b, while the upper end of the thirnble is suitably widened laterally, thus allowing of free oscillation of the bolster 0 upon the surface of the head-block or sand-board B adjacent to the pivot b, on which the bolster rests.

Instead of the thimble c and a rigid bolt, 1), a flexible bolt, G, formed of two rigid sections, 9 g, hinged together, as shown in Fig. 5, may be used, in which case the hole in the bolster may be made cylindrical, and fitting the bolt, as shown in Fig. 6, thehinge in the bolt allowing of the oscillatory movement before stated. To insure, however, that the bolt shall be re tained in tho proper position to present the I hinge as in Fig. 6, allowing no other oscillation of the bolster than sidewise, the head 9 of the bolt G is made oval or oblong, and countersunk into a similar-shaped recess in the bolster O, as shown in Fig. 7.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In combination with the tongue D, pivoted at cl in the hounds E, the reach F, loosely c0nnected to the rear end of said tongue by the parts h h f, the flat platea, and the bail-plate a, for allowing play to the tongue, as set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in pres ence of two witnesses, this 20th day of November, 1882.
