UNITED STATES PATENT OFFICE.
JOHN HENRY SMALE, OF ST. THOMAS, CANADA.
WAGON-BOLSTER SPRING.
SPECIFICATION forming part of Letters Patent No. 506,887, dated October 17, 1893.
Application filed December 15, 1892. Serial No. 455,275. (No model.)
T0 at whom it may concern:
Be it known that I, JOHN HENRY SMALE, a citizen of Canada, residing at St. Thomas, in the county of Elgin, Province of Ontario, Oanada, have invented certain new and useful Improvements in Wagon Springs, of which the following is a specification.
My invention relates to improvements in wagon springs, in which the spring bar having adjustable lugs or plates on each end, operates in conjunction with a semi-elliptic spring having two or more leaves, and a relieving spring, and the objects of my improvements are, first, to provide aremovable spring which may be adjusted to conform to the varying widths of different vehicles; and second, to provide a removable spring for wagons or other vehicles possessing as nearly as possible universal elasticity. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the entire spring placed on the bolster of a wagon. Fig. 2 is a side elevation of the several leaves which compose the spring, and as it appears after all other parts are removed. Fig. 3 is a cross section through the center of Fig. 1. Fig. 4 is a detailed side elevation of the center of Fig. -1. Fig. 5 is a detailed plan of the end of the top part of the spring. Fig.'6 is a detailed elevation of the same.
Similar letters refer to similarparts throughout the several views. 7
A. is the bolster of a wagon, and B. B. are the stakes.
O. is a spring bar, curved upward from the center to the extremities, and being made of steel is capable of carrying light loads.
D. is a relieving spring, which whenthe vehicle is heavily loaded is brought into contact with C. and assists in carrying the load,
E. and F. are semi-elliptic springs, which rest on the bolster of the vehicle and are bound to G. and D. in the center as hereinafter explained.
G. is a clip or case which covers the top and sides of O, D, E, and F. at their points of contact, in the center of their several lengths.
H. H. are adjustable .plates or lugs arranged to be adjusted horizontally to accommodate the varying widths of different vehicles.
I is a belt which passes through the clip or case G, the spring bar 0. the relieving spring D. and the semi-elliptic springs E, and F. and is provided with a nut on the lower end thereof, enabling the said bolt and the clip or case G. to hold the several parts securely in position.
J. .I. are bolts provided with nuts which pass through the ends of the spring bar 0. and the slots in the plates or lugs H. H. (both of which are corrugated at their points of contact as shown in Fig.5) and hold the said plates or lugs in position.
If it is desired to construct a spring capable of carrying a heavier load than usual, additional semi-elliptic spring leaves may be used,
each one conforming to the one on which it is placed.
I am aware that prior to my invention bolster springs have been made with semi-elliptic springs. I, therefore do not claim such a combination broadly, but-- What I do claim as my invention, and desire to secure by Letters Patent, is-
1. In a wagon spring, the combination of a spring bar 0, two (more or less) semi-elliptic springs connected with the bar and adapted to bear upon a bolster or other base, and a relieving spring interposed between the semielliptic springs and the bar and having its ends curved or extended upwardly so as to engage the bar when the same is depressed, substantially as specified.
2. In a wagon or vehicle spring, the combination of a bar having a series of corrugations at its opposite ends; of lugs or plates H, mounted on the ends of the bar and having corrugations adapted to engage those of a bar, and a suitable means for fixing the said lugs or plates in position, substantially as specified.
3. In a Wagon spring, the combination with a bolster and standards or stakes rising therefrom; of a spring bar carrying lugs or plates at its ends adapted to engage the standards or stakes, two (more or less) elliptic springs bearing on the bolster, a relieving spring interposed between the semi-elliptic springs and the spring bar and having its ends curved or extended upwardly so as to 5 engage the spring bar when the same is de- Witnesses:
springs, and a connecting bolt taking through the spring bar, relieving spring and elliptical spring, substantially as specified.
JOHN HENRY SMALE.
pressed, the clip or case G, embracing the 1 W. L. WICKETT, spring bar, relieving spring and elliptical D. D. LONG.
