SPECIFICATION forming part of Letters -:Patent No. 261,611, dated July 25, 1882.
Application flied Decemter 1,1881. V(No model.)
To all whom it may concern: y
Be it known that I,- SAMUEL IDE, of Medina, Orleans county, New York, have invented acertain'new and useful Improvement in Bolster-Springs for Wagons; and I do hereby declare that the following is a full, clear, and exact description ot' the same, reference being had to the accompanying drawings, in which- Figure lis a front elevation of the spring and the bolster upon which it lits. Fig. 2 is a plan ofthe spring, one end of the upper bar being broken away to show the ends of the several leaves. Fig. 3 is a sectional View of one end of the sp1-ing on an enlarged scale. Fig. 4 is a cross-section in line a: w, also enlarged.
My improvement relates to a' spring device made as an independent attachment applicable to the bolster ot' a common farm-wagon, and
removable at pleasure, so that the wagon can be used either with or without springs. The invention consists in the peculiar construction ofthe spring, as hereinafter more fully described.
In the drawings, A indicates the bolster of an ordinary farm-wagon, and B B are the side stakes. The independent spring, which I will describe, fits down upon the bolster and, -is held in place bythe stakes, and the wagonbody is placed between the stakes, resting on top of the spring. The construction ot' the spring is as follows:
C U are two flat wooden bars, one vforming the bottom andthe other the top of the independent sprin g. The ends ofthe bars are provided with square notches a a, which lit over the stakes,'and by this means both bars are secured in place and held in line, while the upper bar plays up and down under the vibration of the wagon and the elasticity ot' the springs interposed between the bars.
D D are two metallic socket-pieces at the ends of the lower bar and tirml y secured thereto. Each of these socket-pieces has a horizontal bar, b, and two side lugs, c c, which serveV the double purpose of a stiiener tothe bar and a guide and stop to the two lower leaves of the spring, as will presently be described.
Between the bars are interposed a series of half-elliptic springs, 1, 2, 3, andY 4, the outer ends of which are entirely free, as shown in Fig. 1. The lower spring, l, is narrower in cross-section than the others, and its loose ends rest against the bars b and between the lugs c c of the socket-pieces, as shown in Fig.
. 3,by which means it is kept in place, and has great stiffness and strength, with a certain degree of elasticity. The other three springs are all secured together and to the upper bar, C, by means of two encircling irons, ff, which form clips, the several springs having washers g g interposed between them, by which they are kept at proper distance apart. The spring 2, which is the lowest one of those clamped together, has a greater degree of con vexity than spring 1 below, and its ends, which are free, simply rest upon the top of the bars b I) and between the side lugs, c c, so that as the spring is borne down by the weight it will slide 0n the smooth bars b b and will be kept in place by the side lugs, c c. The Vspring 2 is longer and overlaps the ends ot' 'spring 1, and the other springs,3and 4,are of gradually decreasing length. A greater or less number of the springs may beused at pleasure. Under a very light load the spring 2 sustains the weight alone, its ends playing between the lugs c c and expanding and contracting under the vibrations. A still heavier load brings down Uspring 3, and a still heavierrone spring 4, so
that the weight is shared by'all of them. The spring 1, beinglstayed at' its ends, forms a bumper and stay to the vibrations of the upper springs, serving to receive the shocks, which it does by reason ofv its stiffness and strength, having, however, suticient elasticity to break the concussions. When it is desired to use a stiff wagon the spring device is removed from the.bolster.
Having thus described my invention, I do not claim broadly a series of h alf-elli ptic springs clamped to the spring-bar and having l'ree ends but A bolster-sprin g consisting of the two springbars C G, fitting loosely between the'stakes' and upon the bolster of the wagon, the spring l, resting upon the lower bar and against 'the stops b b at opposite ends, and the series ot' springs 2 3 4, attached to the upper springbar and having free ends, the lower spring being independent of the upper ones and serving as a bumper to the same, as herein shown and described.
In witness whereof I have hereunto signed my name in the presence of two subscribing Witnesses: SAMUEL IDE.
