COMPLETE SPECIFICATION.
An Improved Timber Wagon.
I, GEORGE HUGHES, of 23, Coleman Street, London, E.C., Patent Agent do
hereby declare the nature of this invention (a communication to me from abroad
by Walker Julian Bond, of Atoka, Indian Territory, in the United States of
America, Inventor) and in what manner the same is to be performed to be par-
ticularly described and ascertained in and by the following statement:-
My invention relates to timber wagons and has for its object to provide such
vehicles with improved means whereby the whole load of timber may be dumped
at once.
In carrying my invention into effect I proceed in or in about the following man-
ner making reference to the accompanying sheets of drawings in which Fig. 1 is
a plan of one of my improved wagons seen from above. Fig. 2 is a longitudinal
section through line 2, 2 of Fig. 1, with a load of timber thereon, the front part of
the timber being shown as broken away. Fig. 3 is a longitudinal section on the
line 3, 3 of Fig. 1 also with the load of timber thereon, the timber being also
shown in its tilted position by dotted lines. Fig. 4 is an enlarged perspective
view of the front cage or frame and holster. Fig. 5 is an enlarged perspective
view of the rear bolster and roller looking at the front thereof. Fig. 6 is an
enlarged perspective view of the rear bolster and roller looking at the rear thereof,
the central portion of the hinged bar being broken away.
Like numerals of reference mark the same parts wherever they occur in the
various figures of the drawings.
Referring to the drawings by the numerals, 10 and 11 indicate the front and
rear wheels, mounted as shown, upon the axles 12 and 13, the usual bolsters 14
and 15 being mounted respectively on the front and rear axles.
The coupling pole 16 is connected to the front axle by the king-bolt 17 and
passed through a mortise 18 in the rear bolster 15. 19 and 20 represent the front
and rear hounds, the rear hounds being provided at their front end with a sleeve 21,
through which the coupling pole 16 freely passes, the said coupling pole being
prevented from being drawn forward through the mortise 18 in the rear bolster
by means of a pin 22. Upon the front bolster is mounted a cage or frame 23 and
from the rear bolster bearings 24 project forward so as to receive the pivots of
the roller 25 extending from end to end of the bolster across the wagon and pro-
jecting slightly above the upper surface of the bolster. A cross-bar 26 is con-
nected to the rear bolster by means of hinges 27 and in its normal position as
shown in Figs. 2 and 6, it rests upon the upper surface of the rear bolster, the
upper surface of the said hinged bar being slightly higher than the upper surface
of the roller 25. A slide-bolt 28 secured to the rear side of the hinged
bar 26 serves when in its normal position, as shown in Fig. 6, to hold the hinged

page_text: bar in its normal position upon the upper surface of the bolster, but when the
bolt 28 is withdrawn upwards the hinged bar 26 will be free to turn on its
hinges.
The operation of my improved timber wagon is as follows. In loading the
timber upon the wagon the forward ends are laid upon the front bolster and
project into the cage 23 while near the rear the timber rests upon the upper sur-
face of the hinged bar 26 which at this time is in its normal position as shown in
Figs. 2 and 6 with the bolt 28 pressed downward. When it is desired to unload
the timber from the wagon the rear wheels are chocked by means of a stone or
other obstruction, as at 29 or by a chain around the spokes of the rear wheel and
braces 30 are provided to connect the front bolster 14 with the coupling pole 16
so as to prevent the front axle turning on the pole. The team is now backed,
which will cause the front wheels to be moved backward while the rear wheels are
stationary, the engagement of the front end of the load of timber with the frame 23
causing the timber to be moved backward also. In the meantime the bolt 28 has
been knocked upward so that the first motion backward of the timber while resting
upon the top of the hinged bar 26 will cause the said hinged bar to be tilted upon
its hinges and the timber to rest upon the surface of the roller 25 by which means
it can be more readily forced backward with the front axle. As soon as the timber
has been pushed backwards sufficiently far to bring the centre of gravity of the
load in the rear of the roller 25 the rear end of the load will drop to the ground as
shown in the dotted lines in Fig. 3 when the team can be pulled forward, drawing
the wagon out to its full length and then drawing the rear wheels, axles, bolsters
and roller out from under the load, permitting the forward end to drop upon the
ground, so that the whole load is dumped in one operation thus dispensing with
the necessity of unloading it piece by piece and greatly economizing the time of
the driver. The usual standards 31 and 32 are provided upon the front and rear
bolsters respectively to prevent the displacement of the load sideways.
While I have described and illustrated the best means now known to me for
carrying out my invention I wish it to be understood that I do not restrict myself
to the exact details of construction shown, but hold that such slight changes as
might suggest themselves to the ordinary mechanic would fall within the area
and scope of my invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In a timber wagon, comprising the usual front and rear wheels axles and
bolsters, the combination therewith of a coupling pole pivotally connected with
the front bolster and slidably connected with the rear bolster, a cage, mounted
upon the front bolster to receive the forward end of the load of timber and a
roller mounted parallel with the rear bolster upon bearings projecting therefrom
and having its upper surface slightly higher than the upper surface of the bolster
substantially as described and illustrated.
2. The combination in a timber wagon of the usual front and rear wheels,
axles and bolsters, a coupling pole pivotally connected with the front bolster,
rear hounds projecting forward from the rear axle and provided at their forward
meeting ends with a sleeve through which the coupling pole passes and a pin in
the coupling pole in the rear of the rear bolster substantially as described and
illustrated.
3. The combination in a timber wagon of the rear bolster the roller mounted in
bearings thereon parallel with the bolster and having its upper surface slightly
higher than the upper surface of the bolster and a cross bar hinged to the holster
parallel with the roller and having its upper surface slightly higher than the
upper surface of the roller substantially as described and illustrated.

page_text: 4. The combination in a timber wagon of the rear bolster, the roller mounted in
bearings thereon parallel with the bolster and having its upper surface slightly
higher than the upper surface of the bolster, a cross bar hinged to the bolster
parallel with the roller and having its upper surface slightly higher than the
upper surface of the roller the normal position of the cross bar being upon the
top of the bolster and a vertically sliding bolt mounted on the hinged bar in its
normal position substantially as described and illustrated.
