IMPROVEMENT IN VEHICLE-SPRINGS.
Specification forming part of Letters Patent N0. 153,908, dated August 1l, 1874; application filed January 21, 1874.
Be it known that I, ASA PIERsON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Springs for Gars, Garriages, Locomotives, Ste.; and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawing.
My invention relates to improvements in springs for cars, carriages, locomotives, and other vehicles; and consists in the employment of projecting ribs made in one piece with the longest leaf, whereby the strength of the spring is increased, and by such construction I am enabled to make a spring with less leaves than ordinarily employed, without decreasing its strength or elasticity, and at the same time render it much lighter than other springs of the same size and strength. The additional leaves of the springs are constructed in the usual manner, and are placed one above the other in the interval between the projecting ribs of the main leaf, as hereinafter described, and shown in the accompanyin g drawing.
In the said drawing, Figure l represents a top view; Fig. 2, a side elevation; Fig. 3, a
transverse section on line A B of Fig. 1, andV Fig. 4 a transverse section on line C D of Fig. 2. Fig. 5 is a transverse section of the main leaf, taken on an enlarged scale.
Similar letters refer to similar parts wherever they occur in the drawings.
a represents the longest or main leaf of a metallic spring. On each side of the said leaf is formed a projecting lip, b, extending at right angles from the main portion, and formed in one piece therewith. 'Ihe ribs b b are made of a sufficient height in the middle to give the required strength, while they taper toward their ends to give the necessary elasticity thereto. The additional leaves c d, one or more, are formed without flanges and placed over each other in the space between the flanges b b, by which arrangement they are held L in their relative positions without the aid of guide-pins, Slot-holes, Ste., usually employed. A clasp, e, is shrunk over the middle ofthe whole spring in the usual manner.
- found deficient in By the employment of the said flanges on i the main leaf I am enabled to reduce the number of leaves of a spring, and consequently make it much lighter than the ordinary sprin g without decreasing its strength, durability, or elasticity.
My improved spring weighs much less than springs as ordinarily constructed of the same strength and elasticity, as it contains less leaves, and can therefore be made at a less expense. It will also retain its strength and elasticity longer than the old kind of springs,
owing to the increased resistance and dura bility ofthe lianges b b.
I do not claim a spring composed of one or more leaves. or pair of leaves having each of their edgestlanged, or formed with uptnrned margins, as I am aware that such is not new; and, besides, a spring so made, while affording the greatest stiffness and strength with the minimum amount of material, does so at the sacrifice of its elasticity while a spring composed of a like number of untlanged leaves, although presenting the requisite elasticity is seeks, by combining the iianged and uniianged leaves, to produce a spring which shall possess both the requisite degree of stiffness and elasticity.
The vehicle-spring having a base leaf or pair of leaves, with projecting anges b b and one or more supplemental unanged leaves, c d, combined as shown and described.
