WAGON-SPRING.

Specification of Letters Patent.

Patented Get. 31, 1916.

Application filed March 8, 1916. Serial No. 82,978.

To all whom it may concern Be it known that I, CrmRLn-s A. GoINs, a citizen of the United States, residing at Tulsa, in the county of Tulsa, State of Oklahoma, have invented a new and useful Wagon-Spring, of which the following is a specification.

The object of this invention is to provide a wagon spring that may be readily attached or detached to the ordinary bolster, so that the wagon body may be. used with or without the springs and so that, in cases where it is desired to utilize the wagon truck without the body the springs may be readily detached and the bolsters will. then be free for any of the conventional uses.

A further object of this invention is to construct a wagon spring of a plurality of spring units of variable tension, each of the units being independent and interchangeable.

A still further object is to provide a spring of this type not only with units of variable tension but wherein the independent elements are constructed so as to have a graduated tension.

With these and other objects in view, reference will be had to accompanying drawings, forming a part of this specification, and wherein like characters of reference designate corresponding parts throughout the several views, in which Figure 1 is a fragmentary perspective of the spring carrying element showing one of the springs in position. Fig. 2 is a front view of one of the bolsters showing the spring in position. Fig. 3 is a fragmentary perspective showing another form of catch, and Fig. t is a perspective of a portion of the base of one of the springs showing the locking rod in dotted lines.

Reference character 1 indicates a bolster upon which is seated a spring carrying member in the form of a beam or bar of rectangular cross section, indicated by 2. This bar or member 2 is secured in position on the bolster by means of U-shaped clips 3 which seat in and engage the grooves i. The king pin 5 is in this instance shown passing through the spring carrying member, however this feature is immaterial as the clips form a satisfactory fastening means.

The spring carrying member is provided with cups or pockets 6 to receive the springs. These pockets 6 are formed in the top of the member 2 and are spaced in a relative predetermined manner according to the type and tension of the springs used. These pockets are of sufficient depth to securely pocket the ends of the springs and one of the walls of each of the pockets adjacent to one of the longitudinal edges of the said spring carrying member 2 is cut away to form a passage or opening to allow the placing or removing of one of the springs from the side. The bottom of the pocket may have an inwardly inclined face as shown at 6 to cause a more effectual seating of the spring. Such a provision is not necessary because of the fastening means provided.

The fastening means may be in the form of a longitudinal. rod 7 which extends through the carrying member 2 in such a manner as to engage one of the coils of the springs, which latter may or may not be provided with a depression for the seating of same.

The springs are preferably of coiled formation and the thickness and strength ofeach of the springs gradually decreases from the base upward, so that resistance against depression gradually increases. The springs are of varied length and tension, the longer springs 9, 9 being located near the extremities of the spring carrying member 2, and the intermediate springs, which may be of any suitable number, are of ever increasing tension and decreasing length as they approach the central spring 10. This latter being of greater strength acts not only as a spring but as a buffer or stop for the wagon body when the other springs have been depressed to their limit. In the present instance there are shown seven springs, including the central or buffer spring 10. As previously stated the other springs gradually increase in length outwardly and tension inwardly, the two springs next adjacent the buffer spring being of equal height and tension, etc., and each of the other sets of corresponding springs on the opposite sides of the buffer spring being approximately equivalents.

In use it will be seen from Fig. 2 that the wagon body indicated by the reference character A normally rests on the longer springs 9, 9 which are secured near the ends of the spring carrying member. When additional weight is placed in the Wagon body these springs will be depreessed and the body will engage and rest upon the second set of s rin s and this movement of the P a: V

' wagon body due to increased weight will the bar 2 continue until finally the body will rest upon the central spring 10 which is of such excessive tension as to act as a buffer and to prethis latch 12 is of resilient material to enable more convenient disengagement from the catch 14:.

Various changes may be made in the details of construction and arrangement with out departing from the spirit of the invention. V V \Vhat I claim as new and useful and desire to secure by Letters Patent, is

1. In a device of thecharacter described comprising a bar springs mounted on said bar, one of the springs being located approximately the longitudinal center the said bar, the remainder of said springs being arranged in pairs, each of the springs of each pair being located on opposite sides of said central spring and each pair of said springs being of equal size and similar tension the size of said springs being gradually increased toward the extremities and the tension of said springs being gradually increased toward the center of said spring carrying bar, and fastening means for said springs.

2. In a device of the character described comprising a bar, pockets formed in said bar, springs mounted in said pockets, the bottom of said pockets having inwardly inclined faces for the reception of the base of springs one of the walls of each of said pockets adjacent one of the longtiudinal edges of said bar being cut away to allow the placing and removal of said springs, one of said springs being located approximately the longitudinal center the said bar, the remainder of said springs being arranged in pairs, each of the springs of each pair being located on opposite sides of said central spring, and each pair of said springs being of equal size and similar tension, the size of said springs being gradually increased toward the extremities and the tension of said springs being gradually increased toward the center of said bar, and means for locking said springs in position comprising a rod extending longitudinally through said bar and engaging same.
