IMPROVEMENT IN PLATFORM-GEARS FOR VEHICLES.
Specification forming part of Letters Patent No. 154,584, dated September 1, 1874; application filed February 28, 1874.
V and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part 7 of this specification, and to the letters and figures of reference marked thereon.
Figure 1 of the drawingisarepresentation of a plan view of my buggy platform. Figs. 2 and 3 are sectional views of the same.
This invention has relation to the construction of platform-gears for buggies and other vehicles; and it consists in combining, with a 4 fifth-wheel, two cross-bars and four arched spring-extensions,and two connecting inverted arches thereof, which latter are secured upon the axle bed, and have attachments on their front ends for thills or a draft-tongue.
The following is a description of my invention.
In the annexed drawings, A A designate four arched spring-extensions, which are fitted, by their inner ends, into, and bolted to, the halved ends of the rigid bars b b, which form the central portion of the supports. Secured upon these bars I) b is, concentrically to the king-bolt, a fifth-wheel, C. These springs A A are suspended from the ends of side springs D D by means of stirrup-connections c c f, so constructed as to allow free play of the four springs, and also a ready detachment front ends are constructed with eyes, for the attachment to them of shafts or a draft-tongue. The draft is thus in line with the side springs D D, and directly from the axle-bed.
These side springs are of the semi-elliptic kind, and they may be composed of a number of leaves, secured together in the usual wellknown manner of making such springs.
The spring-extensions A A are composed of metal leaves a a, rigidly secured to the inflexible bars b b, which latter are, preferably, made of wood, and they have the ring or fifthwheel 0 secured to their upper sides. These rigid bars I) are strengthened, by means of trussed braces c g, so that they will uniformly transfer the weight put upon .them to the four springs.
It will be seen. from the above description, that Ihave an elastic platform-gear, the crossed springs of which are sustained by side springs, which not only serve as means for supporting said crossed springs upon the axle-bed, but they also serve as braces for the crossed. sprin gs. 7
What I claim as new, and desire to secure by Letters Patent, is-
The combination, with the side springs, fifth-wheel, and rigid bars I) b, intersecting at the king-bolt, of the spring-extensions a a, bolted to the ends of said bars I) b, and the truss-braces e g, substantially as specified.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
HARRY S. CLARK.
