ADJUSTABLE SPRING.
SPECIFICATION forming part of Letters Patent No. 759,507, dated May 10, 1904.
Application filed July 29, 1903.
To alZ whom it may concern.-
Be it known that we, JOHN MARSHALL ERIC- SON, CHARLEs ROBERT BERRY, and LUAoINn WILLIAMS Hoes, citizens of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented a new and useful Adjustable Spring, of which the following is a specification.
This invention relates to certain improvements in springs for carriages, wagons, railway-cars, and other vehicles and all other places where springs are used, and more espeoially to novel means for strengthening the spring and regulating the tension thereof.
One object of the invention is to provide a simple, inexpensive, and cificient device of this character by means of which the spring may be lengthened or shortened at will and the tension thereof regulated to meet the varying conditions under which it is used.
A further object of the invention is to provide a double bow-spring, the opposite ends thereof being pivotally connected to a common adjusting-rod, so that when the rod is lengthened or shortened the spring will expand or contract, as the case may be, and the resiliency thereof increased or diminished accordingly.
The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in form, proportions, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
In the accompanying drawings, Figure 1 is a side elevation of aspring constructed in accordance with our invention, showing in dotted lines the adjusted position of the same. Fig. 2 is a top plan View of the same, part of the spring being broken away to show the construction of the adjusting-rod; and Fig. 3 is a detail perspective of a portion of the adjusting-rod and springs detached.
Similar numerals of reference indicate cor- Serial No. 167,447. (No model.)
responding parts in all the figures of the d rawings.
1 designates the spring, which may be of any desired shape or construction and made of metal or other suitable material, being preferably formed of two independent semi-elliptical or bow- shaped springs 2 and 3, pivotally 5 5 connected to a central longitudinally-disposed adjusting-rod 4, as shown. The adj usting-rod 4: is preferably formed in two sections, the inner threaded ends 5 being connected by a turnbuckle 6 and by means of which said rod is lengthened or shortened to regulate the tension of the springs 2 and 3, as will be more fully explained hereinafter. The outer threaded ends of the rod 4; are provided with substantially rectangular-shaped heads 7, held in position thereon by means of jam-nuts 8, each head being provided with oppositely-disposed recesses 9, defining outwardly-extending perforated ears or lugs 10, adapted to receive loops or eyes 11, formed in the ends of the springs 2 and 3, a pin 12, passing through said loops or eyes and the perforations in the cars, serving to pivotally connect the ends of the springs to the adjusting-rod, as shown.
When it is desired to increase the tension of 7 5 the springs 2 and 3, the adjusting-rod is short encd by turning the turnbuckle 6, which causes the heads 7 to draw inwardly on the ends of the springs, decreasing the length thereof and causing the springs to eicpand laterally, as clearly shown in Fig. 1 of the drawings, the pivotal connection between the springs and adjusting-rod allowing lateral play of the springs and preventing undue strain thereon, while regulating the tension thereof. 5 It is obvious by lengthening the adjusting-rod the length of the spring will also be increased and the tension thereof accordingly diminished.
From the foregoing description it will be 9 seen that we have provided an exceedingly simple and inexpensive means for regulating the tension of carriage-springs and the like, the relative disposition of the several parts being such as to permit of a double adjustment-namely, through the medium of the turnbuckle and by adjusting the heads longitudinally on the connecting-rod and clamping the same by means of the jam-nuts.
It is obvious that the springs 2 and 3 instead of being formed, respectively, of a single piece of metal bent into desired shape may be formed of several superposed plates fastened together in the ordinary manner, and various other changes may be resorted to within the scope of the appended claims.
Having thus described the invention, what we claim, and desire to secure by Letters Patent, is
1. The combination with a bow spring, means for eflecting a positive adjustment of the length of the spring, and a pivotal connection between the spring and the adjusting means.
2. The combination with a bow-spring, of an adjusting-rod forming a rigid connection between the ends of the spring, securing-heads longitudinally adjustable on said rod, a pivotal connection between the spring and the secluring-heads, and means for adjusting the roc 3. A device of the class described comprising a spring having its end portions bent inwardly, means for effecting the positive adj ustment of the length of the spring, and a pivotal connection between the ends of the spring and the adjusting means.
4. A device of the class described comprising a pair of springs having their end portions bent inwardly in approximately parallel relation to each other, means for effecting the positive adjustment of the length of the springs,
and a pivotal connection between the springs and the adjusting means.
5. Adevice of the class described compris ing a pair of springs having their end portions bent inwardly in approximately parallel relation to each other and provided with terminal eyes or loops, an adjusting-rod formingarigid connection between the ends of said springs, adjustable heads carried by the rod, said heads being provided with oppositely-disposed recesses adapted to pivotally support the terminal eyes or loops, and means for adjusting the rod.
6. A device of the class described comprising a pair of semi-elliptical or bowed springs having their end portions bent inwardly in approximately parallel relation to each other, an adjusting rod provided with terminal threads forming a rigid connection between the ends of said springs, adjustable securingheads engaging the terminal threads of the rod, jam-nuts adapted to clamp the heads in the adjusted position, a pivotal connection between the ends of the spring and the securing-heads, and a turnbuckle for adjusting the rod.
1n testimony that we claim the-foregoing as our own we have hereto aifixed our signatures in the presence of two witnesses.
