IMPROVEMENT IN RAILROAD-CAR SPRINGS.
Specification forming part of Letters Patent No. 166,179, dated July 27, 1875 application filed January 29, 1874.
CASE B.
To all whom it may concern Be it known that I, JOHN EASTBURN 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 specification My invention relates to the construction of that class of springs which are formed by the grouping of a number of spiral springs.
Figure l 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 0 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 metalic plates to which one end of the spiral springs A A A A and a a a a respectively are firmly attached.
The springs AA A A are made sufficiently large in their interior diameter, to contain within their coils the spiral springs or a a a. They are also made of greater length for a purpose hereinafter stated.
The springs A A A A being attached to the plate B, at such relative distances apart as may be desirable, similar relative distances for attaching springs to a a a to the plate b are then fixed and the springs united thereto.
The grouped springs or a a a. should respectively be passed into the interior of those of the group A A A A until the plate b comes in contact with the ends of springs A A A A, when the construction of the entire dual spring is complete.
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 to 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 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 manner herein described of combining them with the plates; but I do claim as my invention- In a car-spring, the outer spiral spring A firmly attached to the plate B, and having inside of it the spring a, firmly attached to the-plate b, all substantially as and for the purpose set forth.
