VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 397,366, dated February 5, 11889.

Application tiled June 26, 1888. Serial No. 278,285. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN JARRELL, of Harper, in the county of Harper and State of Kansas, have invented a new and useful Improvenient in Vehicle-Springs, ot' which the following' is a specification.

My invention is an improvement in vehiclesprings, and seeks to provide a neat, light, and durable torsion-spring` construction which 1o will support the occupanti or occupants of the vehicle easily, and by which pitchingl and rocking ot' the vehicle will be avoided.

The invention consists in certain features et' construction and novel combinations of parts, as will be hereinafter described and claimed.

In the drawings, lfigure l is a plan view ot the under side of my improvements, the springs on one side bein g lapped and secured 2o together at their inner ends. liig. 2 is a detail perspective view, parts broken away, of one oi' the springs and its t'astenings. Fig. i shows a dit't'erent form of spring from that shown in Fig. 1. Eig. -i shows a differ- 2 5 ent construction, wherein the arms of the spring, instead ot' being bent from the same rod of metal, are separate and secured together by suitable connections; and Fig. 5 shows the connecting-arm formed integral 3o with the spring.

The body-sills A A and the :front and rear springwbars, B l5', constitute in the presentconstruction the framing, to which are secured the springs C G, which are arranged at the 3 5 opposite sides ol the ends of the framing and are independent oi' each other. Thus each part is self-supporting, which causes the vehicle to ride as easy with one or two passengers as with a full load, and to ride smooth and easy 4o on rough roads, a sudden shock or jar does not cause the vehicle to pitch or rock.

lVhere it is desired to stiiten the springs on heavy vehicles, the springs on the same side may have their inner ends lapped and connected together, the connection in the construction shown being a bolt-nut and washer. By s o connecting the spi-in the springs may be caused to equalize eitherin front or in rear, according to which springs are lengthened the 5o most in shiftin g them together. The front or rear springs may be made sti tf or limber by shifting them to lap them, as described, and the front and rear springs may be the same length by using heavy metal in one and light metal in the other.

The springs are formed et' a plurality of arms, c c', are secured rigidly at one end, l, to the framing, and have their other ends, 2,

j ournaled to the framing, so that they may be freely tu rued. 6o

These arms c c may be bent t'rem a single bar of metal, as shown in Fig. l, or may be formed separately and yoked rigidly together,

as shown in Fig. 4. Then desired, the spring, instead of being formed of two arms, may be made with three, four, or more arms, as will. be understood from Fig. lllanifestly, the longer the spring the sot'ter and easier it will be tothe rider. rlhe brackets or clips D are secured to the spring-bars and have sockets (l 7o for the ends l of the springs and bearings CZ,

in which the ends 2 oil such springs journal. The ends l. ot' the springs are secured in sockets d, it may be by wedge-bloclss (Z2, as shown,

or by clam ping-screw or other suitable elamp- 7 5 ing device.

The arm E, which forms the connection between the springs and the runningsgear, is united at its inner end directly with the spring at or near the turning end, 2, thereof, and is 8o iixed rigidly at such end to said spring, so that it can only move by giving a partial turn to the spri1\grod c.

ln Fig. 5 the connecting-arm E is shown as formed integral with and bent from the journaled spring rod or arm. Vhen thus constructed, it will be found desirable to employ a clip, j, 'fastened around the arm E close to its juncture with the spring proper, as shown in said Eig. 5. 9o

By my invention l overcome the disagree able squeaking ordinarily incident to the use of torsional springs, by reason of the attachment of my spring-rods in the manner shown and before described.

The constructions are simple, can be easily and cheaply made, applied, and adjusted, and will be found easy and durable in use.

Having thus described my invention, what I claim as new isl. The combination ot' the framing, the clip or bracket secured to said framing, and the torsion-spring, Consisting of a plurality of arms united or joined together, the free end of one arm being rigidly clamped in the elip or bracket, and the free end of the other arm being journaled in the bracket, thelatter arm being providedelose to the bracket and between the saine and its juncture with the other arm with the Connecting-arm, Substantially as Set forth.

2. A vehicle-Spring formed ot' a pluralituxvv of arms united together at one end, one of such arms being bent outward near its free end to form a connecting-rod, and provided beyond Such connecting-rod with a trunnion-like eX- x 5 tension, substantially as set forth.

3. The combination of the framing, the torsion-springs arranged at the opposite sides of the ends thereof, secured to the framing and projected inwardly toward eaeh other, the 'front and rear springs on the Same Side being lapped together at their inner ends, and e011 neetions for uniting the inner lapped ends of Said Springs, Substantially as Set forth.

EDWIN JARRELL.
