VEHICLE- SPRING.
SPECIFICATION forming part of Letters Patent No; '387,1872, datd December 3,V 1901;
Application filed April 27, 1.901.
'o tif/ZZ whom, t may concern:
Beit known that LHEZEKIAH PRESTON COX, a citizen of the United States, residing at Marietta, in the county of Washington and State of Ohio, have invented a new and useful Vehicle-Spring, of which the following is a specification.
This invention relates to vehicle-springs, and has for its object to provide certain new and useful improvements whereby the body of a vehicle is maintained level wherever the load may be placed thereon and a light load is as effectively' cushioned as a heavy load. It is furthermore designed to arrange the device so that it may be applied to any ordinary wagon without altering the same and also to relieve strain from the axles when the wagon is heavily loaded.
With these and other objects in View the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the drawings, and particularly pointed out in the appended claims', it being understood that changes in the form, proportion, size, and minordetails may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention. Y
In the drawings, Figure l is a bottom plan view of the present spring applied to a vehicle-body. Fig. 2 is a longitudinal sectional view thereof in its normal position. Fig. 3 is a detail perspective view of one of the terminal spring members. Fig. 4 is a detail perspective view of one of the intermediate spring members. j
Like characters of reference designate corresponding parts in all of the figures of the drawings.
Referring to the drawings, 1 designates the bottom of an Vordinary vehicle-body, which is supported upon the front and rear axles `2 and 3, respectively, by means of the present form of spring. These parts are common and well known, and as they form no part of the invention their form may be varied at will.
In carrying out the invention there is provided a pair of duplicate terminal spring members mounted upon the respective axles, one of such members being shown in Fig. 3
of the drawings. Each of these members is Serial No. 57,824.. (Nomodel.)
formed from a single spring rod or bar, the intermediateportion of which is straight, as at 4t, and at the opposite terminals thereof the opposite spring-arms 5 extend forwardly in the same direction at substantially right angles to the rock-bar portion 4. Adjacent to the outer end of each arm the same is bent into a vertically-disposed spring-coil 6, and from the coil the rod is bent laterally inward, as at 7, and then bent outwardly into a link member 8, substantially parallel with the spring-arm and terminating in an eye 9, the opposite links being separated by a suitable space for the reception of the link of the adjacent intermediate spring member, as will be hereinafter explained. Each axle isprovided with one of these terminal spring members, the rock-bar portion thereof being disposed longitudinally across the top of the axle and mounted or journaled in suitable bearings 10, so as to swing vertically thereon as a pivotal center, the main portion of the member being projected inwardly from the axle and beneath the adjacent end of the vehicle-bottom. The cross-bars 7 lie transversely beneath the body and have their outer ends connected to the bottom thereof by means of the respective hangers 11, and their inner end portions journaled in the respective hangers 12- upon the bottom of the vehicle. As best indicated in Fig. 2 of the drawings, it will be seen that the link 8 inclines downwardly and outwardlyl in opposition to the side arms 5, so that these parts lie out of contact with the vehicle-bottom.
Between the opposite terminal spring members are a pair of duplicate intermediate springmembers, one of which has been shown in detail inFig. 4 of the drawings. Each of these intermediate members is formed from a single spring rod or bar, which is bentintermediate of its ends into a link 13, the rod portions lying close together, with theV bent end of the link formed into a longitudinallyelongated loop or eye 14,forming a slotted terminal. The opposite end portions of the rod are bent laterally outward in opposite directions into the cross-bars 15, which have their outer ends bent back in the direction of and substantially parallel with the link and forming arms 16, the outer terminals of which are flattened and perforated to form attaching- IOO bracket-s 17 for application to the under sideV of the vehicle-bottom, as shown in Fig. 1. Each intermediate spring member has its terminal brackets secured to the bottom of the vehicle, with its intermediate link projected outwardly and lying between the link members of the adjacent terminal spring member, the link 13 being inclined` downwardly and outwardly, so that its slotted terminal may normally lie in alinement between the corresponding eyes or slotted terminals of thelink members 8. A suitable pin 18 is passed through the alined slotted portions or eyes and normally lies at the inner terminal of the slot in the intermediate link.
When acomparatively light weight is placed upon the vehicle, the body thereof will move downwardly by reason of the terminal spring members swinging downwardly upon their pivotal connections with the respective axles, whereby the pins 18 will travel in arcs struck from the respective rock-bars 4 as centers,
thus drawing the pins outwardly through the slots of the intermediate links, the friction between the pins and the intermediate links retarding the downward swing ofthe terminal members and placing a torsional strain upon the intermediate spring members, thus giving elasticity to the Vehicle-body when supporting a light load. When the pins have traveled to the outer ends of the slots in the intermediate links, the respective pairs of ter-v minal and intermediate spring members become interlocked againstindependent movement and the strain is thrown upon the spring-coils of both terminal members for the support of a heavier load. Under the strain of a heavy load the spring-coils are contracted, thereby giving increased length to the terminal spring members and automatically compensating for the increased distance between the opposite rock-bars, and thus relieving strain from the axles.
From the foreging description it is apparent that the intermediate spring members are brought into action under the weight of a light load, while the outer terminal members are unaffected thereby and are only brought into action under a heavy load. This feature is highly important with the present invention, as the springs are especially designed for application to vehicles for transporting nitroglycerin in mining districts, wherein Y the original load is heavy and is supported by the terminal sprin g members. After'the load has been gradually diminished by unloading the torpedoes along the route of the vehicle the strong terminal spring members will become unaifected by the comparatively light remaining load, which ordinarily is a dangerous condition; but the light load aects the intermediate spring members and is effectually cushioned thereby and danger of explosions is thereby obviated.
What is claimed is-- 1. The combination with a vehicle-body, and the running-gear thereof, of opposite terminal spring members having their outer ends pivotally mounted upon the runninggear, and their inner end portions secured to the body, and provided with inwardly and downwardly inclined links, and a pair of intermediate spring members secured to the intermediate portion of the body, and having outwardly and downwardly inclined links, there being a slidable connection between the link of each intermediate member and the link of the adjacent terminal member.
