UNITED STATES PATENT OFFICE.
JOHN E. WOOTTEN, OF READING, PENNSYLVANIA.
IMPROVEMENT IN RAILROAD-CAR SPRINGS.
Specification forming part of Letters Patent No. 166, [78, dated July 27, 1875; application filed January 29, 1874.
CASE A.
To all whom it may concern:
Beit known that I, JOHN EAsrBURN WOOT- TEN, of Reading, in the county of Berks and State of Pennsylvania, have invented certain Improvements in the Construction of Springs for Railroad-Oars, of which the following is a My invention relates to the construction of that class of springs which are formed by the grouping of a number of spiral springs.
Figure 1 is a perspective view of a spring embodying my invention. Fig. 2 is a plan of same. Fig. 3 is a sectional elevation on line C D. A A A A a a a a are spiral springs, which may be made of steel, iron, or other desirable metal. B B are metallic plates to which one end of the spiral springs A A A A, respectively, are firmly attached. The springs A A A A are made sufficiently large in their interior diameter to contain within their'coils the spiral springs a a a a. They are also made of greater length, for a purpose hereinafter stated. Before uniting the ends of the springs A A -A A With the plates B B, the springs 0i a at a,
respectively, are placed within the coils of springs A A A A, the ends of the springs aa a a being, however, kept free from any union or attachment to either of the plates B B.
As hereinbefore stated, the springs A A A A are longer than a a a a, the object of which is to permit them to receive the Weight of the empty car unassisted-by the shorter springs a a a a, the latter being only brought into action when the car is loaded, thus permitting a greater degree of spring action, and consequently reduced wear and tear, while the car' is running empty or with a comparatively light load. I
I make no claim to the use of a .group of spiral springs attached to a plate or plates, for I am aware that such a construction is not new. Nor do I claim, broadly, the employment of concentric springs, irrespective of the specific manner herein described of combining them with the platesybut I do claim as my invention- In a car-spring, an outer spiral spring, A, firmly attached at its ends to the plates B B, and having inside thereof the shorter spring a, free at its ends, all combined substantially as and for the purpose set forth.
JOHN EASTBURN WOOTTEN.
