IMPROVEMENT IN ADJUSTABLE SUPPORTING-SPRINGS.
Specification forming part of Letters Patent No. 127,569, dated June 4, 1872.
inders of vulcanized elastic gum or metallic spiral springs,which, respectively, abut against the outer sides of said end blocks, and are retained in position thereat by respective screwnuts on the ends of said tie-bar, and serve also as means of adjusting the distance apart of the two end blocks, and consequently the distance apart of the top and bottom blocks; the object of my invention being to produce a readily adjustable and easy supporting-spring for cars,wagons, carriages, or any other weight or burden which requires to be supported by a reliable and easy spring.
Referring to the drawing, AA are respectively the top and bottom blocks; B B, the end blocks; 0 O, the series of intervening bars; D, the tie-bar; E E, the end cylinders of elastic gum; and F F, the screw-nuts, whereby the relative positions of the blocks and bracing-bars to the tie-bars and elastic cylinders are adjusted and maintained. The blocks A A are each made of solid metal, and have two separate parallel recesses or transverse mortises, 2 2, with curved, concave, smooth bottoms in each of their two opposite sides, and into these are fitted the respective flattened and rounded inner ends 3 3 of the series of bracing-bars O C, so that the rounded inneredges of the said flattened ends will correspond with and bear accurately against the said curved concave bottoms of the recesses or mortises 2 2, and be retained therein loosely by pivots 4 4 and so, also, that the said rounded edges 3 3 of the bars will have an easy sliding bearing against the curved bottoms 2 2, when the spring is in use as such. The two end blocks B B and the respective outer ends 5 5 of the series of bracing-bars G O are articulated together, substantially in the same manner just described, as the top and bottom blocks A A, and inner ends 3 3 of the same series of bracing-bars O O. The end cylinders E E are, in this instance, each made of vulcanized gum-elastic, and with a hole longitudinally through its center of sufficient size to allow the cylinder to be slipped on to its respective end of the tie-bar D, which latter is a straight rigid bar of tough iron, screw-cut to the length of three or four inches from its respective ends, and fitted with traversing screw-nuts F F. The length of the bar I) should be such as will bring the connected bearing-blocks and bracing-bars into the relative positions shown in Fig. 1, where the elastic cylinders E E, or their equivalents, are abutted against the end blocks B B, and retained by the screw-nuts F F, with thin washers 6 6 between.
In the operation of this spring, the burden acts, first, upon the top and bottom bearingblocks A A, pressing them toward each other; secondly, through the series of bracing-bars G 0, upon the two end bearing-blocks B B, pressing them further apart from each other; and, thirdly, upon the elastic cylinders or springs E E, compressing them against the stationary washers 6 6 and screw-nuts F F and it will, therefore, be seen that the elasticity of my said improved spring depends upon the elasticity of the cylinders E E, or their equivalent spiral springs; and that the length of the movements of the burden in either direction will be considerably greater than the synchronous movements of the end blocks B B, and consequently of the longitudinal contractions and expansions of the elastic cylinders E E or their equivalents, and therefore the movements of the burden will be proportionately easier. It will also be seen that the elastic supporting-power of said spring can be readily and accurately adj Listed at any time to The adj List-able supporting-spring, constructsuit the burden which it is intended to suped and operating substantially as hereinbefore pert, at any difi'erent periods of time, by set forth and described.
