SPRING.
Application filed November 4, 1881.
To all whom it may concern:
Be it known that I, ROGER A. MOLEAN, of West Bay City, in the county of Bay and State of Michigan, have invented a new and useful Improvement in Springs, of which the follow ing is a full, clear, and exact description.
My invention consists of a box or well castwith vertical channels in which are loosely upon and across or at right angles to each to move downward either at their ends or in the center in answer to the load, the whole being surmounted with a suitable follower attached to or separate from the load.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.
Figure 1 is a plan view of my improved spring, the follower being removed; and Fig. 2 is a sectional elevation taken on the line was tion. t
A represents the well or box, which is prefresponding channels a a and b bin the opposite walls,andwiththecornerenlargeincntsorchannels d d; and 13 represents the wring-metal strips", which in this instance are all of the same size and length. These strips are placed loosely in the channels of the well or box in pairs, alternately at right angles to each other, and are arranged so that the pairs of parallel strips rest alternately upon the ends and near the center of'the strips, which are at right angles to them, as shown in the drawings.
Upon the pile of strips in the box or well is placed the follower D, which is provided with (No model.) 4
a downwardly-projecting flange, c, and which completes the spring. Thus formed it will be seen that the spring will be durable, as the strips are required to bend but slightly, simple to make, owing to the strips being plain pieces of spring metal and all of the same form and length, easily and cheaply repaired, as it is necessary only to supply the place of the broken strips with new ones, and requiring no mechanical skill, and that the spring will not.
be wholly inoperative and worthless should one or more of the strips become broken, as is the case with springs of ordinary construction. I am aware that it is not broadly new to arrange a series of plates at right angles to each other in a box, with the ends of one set resting in vertical grooves in the sides of the box;
and near the center of the p iirs of the box A,
pro\ided with the channels or grooves a b in its inner walls to receive the ends of theinner plates, and the corner enlargements or channels d to receive the ends of both sets of outer plates, substantially asand for the purpose set forth.
