JOHNSON M HOOPER, SR., AND JAMES R. DANIELS, OF SAN ANTONIO, TEXAS.
TRUCK.
SPECIFICATION forming part of Letters Patent No. 623,669, dated April 25, 1899.
Application filed December 19, 1898. Serial No. 699,719. (No model.) ,To all whom it may concerm:
Be it known that we, JOHNSON M. I-OOPER,
Sr.,'and JAMES R. DANIELS, citizens of the
United States, residing at San Antonio, in the
5 county of Bexar and State of Texas, have in-
vented a new and useful Truck, of which the
following is a specification.
The invention relates to improvements in
trucks.
To The object of the present invention is to
improve the construction of trucks and to pro-
vide a simple, strong, and inexpensive one
adapted to be arranged in a low position to
receive a load and capable of readily elevat-
15 ing the same to enable the load to be conven-
iently transferred from it to a wagon, car, or
the like.
A further object of the invention is to pro-
vide a truck of this character which can be
20 readily employed as a jack for lifting vehicle-
axles to enable the wheels to be removed and
replaced
The invention consists in the construction
and novel combination and arrangement of
25 parts, as hereinafter fully described, illus-
trated in the accompanying drawings, and
pointed out in the claims hereto appended.
In the drawings, Figure 1 is a perspective
view of a truck constructed in accordance
30 with this invention. Fig. 2is a longitudinal
sectional view of the same, the upper or load-
receiving frame being shown elevated in full
lines and lowered in dotted lines. Fig. 3is a
transverse sectional view. Fig. 4 is a detail
35 sectional view illustrating the construction
of the ratchet mechanism.
Like numerals of reference designate cor-
responding parts in all the figures of the draw-
ings.
40 1 designates a lower rectangular truck-
frame,which is connected at its sides by a series
of links 2 with an upper load-receiving frame 3,
which is adapted to be lowered to the position
illustrated in dotted lines in Fig. 2 of the ac-
45 companying drawings to receive a load and
is capable of being elevated to the position
shown in full lines in the said figure for the
purpose of enabling the load to be readily
transferred to a wagon or car. The lower
50 frame 1, which is rectangular, is provided atopposite sides with bearings for axles 4, hav-
ing wheels 5, and although a pair of axles is
illustrated in the accompanying drawings, yet
it will be clear that three or more may be em-
ployed, according to the character of work for 55
which the truck is designed to be employed.
Each pair of links may be constructed of a
single piece of metal; but they are preferably
composed of separate bars connected by a
transverse rod 6, arranged at their upper ends 6o
and passing through eyes thereof, as clearly
illustrated in Fig. 3 of the accompanying
drawings. The lower ends of the links are
bent inward to form pivots 7, which are ar-
ranged in suitable perforations of the side 65
bars of the lower truck-frame 1. Instead of
arranging the transverse connecting-bars (
at the top of the links, they may pass through
the side bars of the bottom frame, and their
ends are threaded for the reception of nuts 8. 70
The lower frame 1 is supported at a point
between its ends by a transverse rod 9, and
it has pivoted between the front ends of its
sides a pole or tongue 10, which forms a lever
for elevating the load. The pole or tongue10 75
is provided at its inner end with a transverse
bar, which forms the pivot, its ends being re-
duced to form journals 11 to fit in bearing-
openings of the frame 1; but any other suit-
able means may be employed for fulcruming 80
the combined tongue and lever 10 on the bot-
tom frame. The tongue 10 is provided at its
lower face with a series of notches 12, ar-
ranged at intervals adjacent to its inner end
and adapted to receive a bail-shaped rod or 85
connection 13, which is pivoted to opposite
sides of the front end of the upper frame 3.
When the connecting rod or bail 13 is en-
gaged in one of the notches of the pole or
tongue, uhe latter is adapted to be swung out- 90
ward and downward to elevate the upper
frame, which is locked in its adjusted posi-
tion by a longitudinal ratchet-bar 14. The
ends of the bail-shaped rod or piece 13 are
bent inward to form pivots for engaging bear- 95
ing sockets or openings of the upper frame 3,
and the central portion of the bail-shaped
rod or piece is bent into substantially rectan-
gular form to fit the tongue or pole, which is
provided at its lower face with a longitudinal ioo
