Specification of Letters Patent.
Patented Get. 29, 1912.
Application filediune 7, 1912. Serial No. 702,215.
T all whom it may concern.
Be it known that I, CAnLosL. THoniP- soN, a citizen of the United States, residing at Marshall, in the county of'Daneand State of Wisconsin, have invented certain new and useful Improvements in Bolster- Springs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to spring bolsters.
The first object of my invention is to provide a hollow metallic bolster containing a series of springs, with which cotiperates a cap resiliently supporting a wagon body.
The second object of my invention is to provide a spring bolster with non-frictional wagon body retaining means.
Other objects and advantages may be recited hereinafter and in the claim.
In the accompanying drawings which form a part of this application, Figure 1 is a front elevation of the front axle and sand bar of a wagon of my spring bolster applied thereto. 0n the line 2:2 of Fig. 1, and Fig. 3 is a sectional view on the line 3-3 of Fig. 1. Fig. 4 is a view showing a modification of the partitions for separating the springs.
Referring more particularly to the drawings in which similar reference characters designate corresponding parts throughout the several views, 1 represents the axle and 2 the sand bar or other supporting means carried thereby. These named elements form no part of my invention, being merely shown for the purpose of more clearly showing the application of my invention to the ordinary form of wagon.
Disposed above the sand bar 2 is a hollow bolster 3, within which are provided a series of partitions 4 for the purpose of forming suitable housings for the coiled springs 5. The central portion of the bolster is enlarged as at 6 to provide a housing for the large spring 7, the under side of said enlarged portion being provided with a bearing plate 8 adapted to cotiperate with a similar bearing plate 8 carried by the sand bar 2. The bolster 3 is secured upon the bearing plate 8 for rotation by a king bolt Fig. 2 is a sectional view 9. The bottom of the bolster 3 between each partition i is provided with an opening 10 to allow accumulation pf dirt or dust'to fall therethrough. As seen in Fig. 3, the springs 5 are of greater length than the height of the bolster 3, and projecting a distance from the upper end thereof.
Disposed over the bolster 3 and resting upon the upper ends of the springs 5 is a cap 11, having the central portion thereof enlarged to correspond with the enlargement 6 of the bolster 3. The cap 11 is formed from a section of substantially U- shaped metal which fits over the bolster 3 and has the opposite ends thereof cut away as at 12. Adjacent the opposite ends of the cap 11 are secured side standards 13, which are adapted to engage and retain a suitable wagon body (not shown) upon the cap 11.
To provide guides for the side standards 13 and cap 11, I provide the bolster 3 adjacent opposite ends thereof, with looped guide bars 14. Non-frictional rollers are rotatably secured between the opposite sides of the guide bars 14 for reducing the friction between the side standards 13 and the guide members 14 and for limiting the upward movement of the cap 11.
It will be seen in the foregoing that I have provided a durable and eflicient spring bolster which will materially reduce the shocks by absorption. It will further be seen that I have proi'ided a movable shock absorbing cap which will effectively and non-frictionally support a wagon body or name to this specification in the presence of two subscribing witnesses.
