NITED STATES PATENT OFFICE,

JOHN DIEHL, OF FRANKSVILLE, VISOONSIN.

SPECIFICATION forming part of Letters Patent No. 396,272, dated January 15, 1889. Application filed August 24, 1888. Serial No. 283,653. (No model.)

T0 all whom it may concern:

Be it known that I, JOHN DIEHL, of Franksville, in the county of Racine, and in the State of Visconsiinhave invented certain new and useful Improvements in /Tehicle-Springs; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to vehicle-springs, being designed as an improvement on the device set forth in Patent No. 379,763, dated March 20, 1888, said invention consisting in certain peculiarities of construction and combination of parts to be hereinafter described with reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure l represents a side elevation of myimproved vehicle-spring with parts broken away; Fig. 2, a plan view of the same; Fig. 3, an under side view of an adjustable socket and guide that is secured to each end of the spring-bar, and Fig. 4 a detail plan view of a portion of my device.

Referring by letter to the drawings, A represents a bar having each end thereof provided with recesses B C, that are preferably extended through said bar. Over the openings thus formed are bolted or otherwise suitably secured metallic plates D; but it is obvious that the recesses B C may only extend part way through the bar A, and in such a case the plates D would be omitted. y

Bolted or otherwise suitably secured to the central portion of the bar A, and preferably between the latter and a stay-plate, E, is a semi-elliptic spring, F, having upwardly and outwardly curved ends, F, recessed, as shown at G, to straddle the adjacent standards II of a bolster, I, the latter being shown as provided with rub-irons I for said ends of spring' F. By havingthe ends of the semi-elliptic spring F straddlethe bolster-standards H there is no liability of said spring being displaced from the bolster I by any jarring or wrenching of a vehicle to which my device may be applied. Adjacent to the recesses Gin its ends the semi-elliptic spring F is provided with lugs J, and surrounding these lugs are spiral springs K, that extend up into the recesses O in the ends of the bar A.

Arranged in the recesses B in the bar A are spiral springs L, having their upper ends in the form of eyes L for rivets M, that pass through the metallic plates D and thereby suspend said springs.

Vertically depending from the stay-plate E, on each side of its center, is a short spiral spring, N, and these springs, on coming into play, bear upon a rub-iron, O.

Sockets P, provided with slots Q, are slipped onto the ends of the bar A, said sockets being ad j ustably held in place by means of set-bolts R passing through said bar and slots. The under sides of the sockets P are provided with recesses S, in order to obtain clearance for the spiral springs K, and the outer ends of said sockets are provided with lugs T, that come on opposite sides of the bolster-standards H, to prevent displacement of the bar A, said lugs having downwardly-projecting extensions T', designed to come upon the upwardly and outwardly curved ends F of the Asemi-elliptic spring F when the resistance of the latter and the spiral springs K, L, and N is overcome by a load. l/Vhen the lugs T come upon the ends F of the semi-elliptic spring F, a further elastic resistance is offered to the load, because by their peculiar shape said ends are springs in themselves, and the result of the operation just described is an equalization of the strain upon the main portion of said spring F.

By employing the adjustable sockets P the bar A is readily lengthened to accommodate the same to the slight differences in width between the bolster-standards H that occur in vehicles of different makes; and by the general construction and arrangement of parts above described it will be seen that I provide a very simple and durable spring capable of supporting heavy loads and not liable to be wrenched or jolted out of position.

It is obvious that the spiral springs K, L, and N may be omitted, and the sockets P employed in connection with a spring composed ofthe bar and semi-elliptic spring above described.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A vehiclespring comprising a bar, a semi-elliptic spring secured to the central portion of the bar, and sockets adjustably se- IOO cured to the ends of said bar and provided with lugs designed to come on opposite sides of bolster-standards, substantially as set forth.

2. A vehiclespring comprising a bar, a semi-elliptic spring recessed at its ends and secured to the central portion of the bar, and sockets adj ustably secured to the ends of said bar and provided with lugs designed to come on opposite sides of bolster-standards, substantially as set forth.

3. A vehicle-spring. comprising a bar, a semi-elliptic spring secured to the centra-l portion of the bar and having upwardly and outwardly curved ends, and lugs depending from said bar to come upon said ends of the seinielliptic spring, substantially as set forth.

4t. A Vehicle-spring comprising a bar, a semi-elliptic spring secured to the central portion of the bar and having upwardly and out` wardly curved ends, and sockets adjustably secured to the ends of said bar and provided with lugs having downward extensions, substantially as set forth.

5. A vehicle spring comprising a bar, the semi-elliptic spring I1", secured to the bar to have its ends rest upon the vehicle-bolster, and the springs L, arranged to depend 'frein the bar and be normally out of contact with said seinielliptic spring, substantially as set forth.

G. A Vehicle-spring comprising a bar, a single semi-elliptic spring secured to the central portion of the bar, and two spiral springs of different lengths arranged to depend from each endv of said bar, whereby one of the spiral springs ineach pair is always in contact with the seini elliptic spring and the other normally out of contact therewith, substantially as set forth.

7. A vehicle-spring comprising a bar, a single semi-elliptic spring secured to the central portion thereof, two spiral springs of different lengths arranged to depend from each end of the bar, and short spiral springs depending `froin beneath said semi-elliptic spring, whereby one of the spiral springs in each pair is always in contact with the semi-elliptic spring and the other normally out of contact therewith, substantially as set forth.

S. A vehicle-spring comprising a bar provided at each end with the recesses B C, the se1ni-elliptic spring F, the spiral springs K, arranged in the recesses C of the bar and iinpinged against the ends of said seinielliptie spring', the springs L, arranged in the recesses 13 of said bar and having their upper ends provided with eyes L', the plates D, and the rivets M, connecting said eyes and plates, substantially as set forth.

9. A vehicle-spring comprising the bar A, adjustable sockets P, arranged on the ends thereof and provided with lugs T, having extensions T, the semi-elliptic spring F, having the upwardly and outwardly curved ends F, and the spiral springs K L, of different lengths, suspended from said bar, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set iny hand, at. Oakwood, in the county of Milwaukee and State of Tisconsin, in the presence of two witnesses.

JOHN DIEIIL.
