Complete Specification Left; 14th Mar., 1895 Accepted; 22nd: June, 1895
residing at Fresno, in the County of Fresno and State of California, one of the
United States of America, Physician, having a place of business in Fiske Block,.
Fresno, do hereby declare the nature of this invention, and in what manner, the
same is to be performed, to be particularly described and ascertained in and by the
following statement:―
Figure 1 of the drawings is a representation of a bottom plan of the invention
applied.
Figure 2 is a side elevation of the same, with wagon body lifted off the
springs.
Figure 3 is an enlarged bottom plan of journal box and collar.
Figure 4 is a section on line x-x Figure 3.
Figure 5 is an end view of fork.
This invention has relation to certain new and useful improvements in vehicle
springs, the object being to provide a simple and efficient spring support for vehicle
bodies having means for preventing lateral motion of the body, and for preventing
the displacement of the attachment bolts; and the invention consists in the novel
construction and combination of parts, all as hereinafter described and pointed out
in the appended claim.
Referring to the accompanying drawings, the letter A designates the body of a
vehicle, to which I have shown my improved spring applied.
B, B', designate transversely extending torsional bars or levers, one of which is
provided near each end of the body upon the under side thereof. Said bars or
levers are each provided with side arms a, which are secured to the bolsters C of
the running gear, or directly to the axle-trees, by means of clips c', or by simple
pivot connections. The central portion of each of said bars or levers is formed
with cranks D, D, opposite cranks being connected by longitudinal helical
springs E.
Between said springs is a longitudinal bar F, baving a fork at each end
portion, said forks embracing respectively the portions of the bars between the
cranks.
At g, g, each of said bars is provided with journals, which bear in boxes h on
the lateral portions of the body A. Owing to the wear of these journals, the body
would be permitted a lateral or side sliding motion accompanied by more or less
rattle, and to prevent this I provide the collars j, which effectually prevent such
wear. The boxes consist each of a grooved block, bolted to the side of the body,
and having a removable bearing block h', held in place by a key h³ engaged by

page_text: the bent arm of a bolt h³. In order to prevent said bolt from becoming loosened
by the jar of the vehicle, and thus permit the body to be thrown off the spring,
I bend its end portion into engagement with a groove or depression h³ in the
block h. An oil hole i may be provided for said bearing, said hole extending up
through the body of the vehicle.
The forked ends of the bar F are preferably of the form shown in Fig. 5,
having each a groove k to retain lubricant.
It will be observed that the springs as above described while effectually
preventing lateral movement of the body, permit the latter a free up and down
movement, making an easy riding vehicle, the springs adapting themselves to the
different loads; also that the body may be readily removed and replaced upon the
springs.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is: :-
The herein described vehicle spring, comprising a pair of transverse torsional
bars or levers B, B', having loose bearings on the under side of the vehicle body,
and having each arms or cranks loosely connected with the running gear, said bars
or levers having also central cranks, the helical springs connecting opposite of
said cranks, the bar having its end portions loosely engaging said bars or levers
between their central cranks, and means for preventing lateral movement of the
said bars or levers and the displacement of the attachment devices which secure
them to the vehicle body, substantially as described.
Dated this 14th day of March 1895.
