Improvements in Wagons.
I, MARCUS WHITMAN MONTGOMERY, a citizen of the United States of
America, residing at No. 45 Warren Avenue, Chicago, Cook County, Illinois,
U.S.A., Gentleman, 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 :—
My invention relates to certain improvements in wagons especially designed for
the transportation of coal or other aricles of the kind, in which the ease of loading
and unloading is of particular importance, and it is particularly desirable that the
wagon itself be so constructed as to be handled with the greatest facility in a
small space.
My improvements are illustrated in the drawings by means of four figures, of
which,
Figure 1 is a side elevation of a complete wagon showing a portion of the rear
box in central vertical section ;
Figure 2 is a plan of the same wagon;
Figure 3 is a front elevation with portions removed; and
Figure 4 is a detail of one of the parts which are removed in Figure 3.
In these drawings, the wheels are lettered A, the front axle B, and rear axle C,
the forward box, D, and the rear box, E. Both of these boxes have inclined
bottoms slanting downward toward the middle of the wagon, and both are supported
directly from the axle, so as to be raised or lowered thereon for the purpose of
loading or unloading. Each one of the axles is provided with an upwardly
extending pin, F, (see the rear box in Figure 1). About these pins are hollow
screws, G, internally screw-threaded to fit the pins which are also threaded; and
said hollow screws are also externally threaded to fit nuts, H, secured in the bottoms
of the boxes. The threads upon the hollow screws run in opposite directions, and
said screws are provided at the top with heads, g, provided with holes, g', adapted
to receive a bar by means of which the screw may be turned. By reason of the
oppositely threaded outer and inner surfaces of the screws, the turning of the
screws in one direction raises the boxes upon the screws, and, at the same time,
raises the screws upon the pins. By this means the boxes may be raised to a con-
siderable height without requiring the screws to be made unnecessarily long so as
to project too far above the boxes when the latter rest upon the axles directly.
As soon as the boxes are raised sufficiently to clear the other parts of the wagon,
they can be turned easily upon the screws so as to discharge their contents in any
desired direction.
From the rear axle upon opposite sides of the box, two rods or bars, 1, 11, extend
forward and upward and are connected with an annular plate, J, of sufficient size
to encircle the forward box. This plate is large enough to allow the forward box
to turn easily in it, and also is arranged at a sufficient height to allow the forward
wheels to pass under it in cramping the wagon. From the forward axle two
rods, K, K, extend backward and unite behind said box to support a pivoted bar, k,
arranged to oscillate vertically and provided at its opposite ends with pulleys, or
rollers, k¹, running upon the inner edge of the annular plate, J. Another pair of
rods, K2, K³, extend forward from the front axle and unite in front of the box to
support a similar pivoted bar, A, bearing similar rollers, ³, also running upon the
inner edge of the plate. The annular plate together with the four rollers and the
parts by which they are supported from the front axle comprise a fifth-wheel large
enough to encircle the box, so that the latter can be both raised and turned in it.
Extending forward from the rods, K2, K³, are bars, K, K', supporting vertical

page_text: ways, K', K', in which a block, L, is supported and clamped in any desired vertical
adjustment by means of set screws, 1. This block, L, is hollowed out upon its
forward surface to fit the rump of a horse and it is made vertically adjustable as
before stated, so that it may be adjusted to any position desired. The wagon here
represented, is intended to be drawn by a single horse pulling within the shafts, M.
The adjustable block or abutment, L, is designed to assist the horse in backing,
and to give him a much better purchase upon the load than the common devices
now in use.
The deeper ends of the two boxes are provided with end-gates of ordinary con-
struction, so that when the boxes are in the position seen in Figure 1. both loads
will be dumped at the middle of the wagon. The provision for raising the
boxes is to enable the loads to be dumped into a chute at a sufficient elevation to
be carried by the latter to the point desired. When it is necessary, as it often
happens, to dump the load at the side of the wagon, the boxes may be elevated
sufficiently to clear the other parts and be swung in any direction desired.
I recognize the possibility of more or less variation and therefore do not desire
to limit myself, except as particularly specified in the following claims :-
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
1-The combination with the wheels and front and rear axles of a wagon, of
separate boxes mounted upon said axles, a frame secured to the front axle, a reach
secured to the rear axle, and a fifth-wheel of sufficient size to encircle the forward
box secured to said reach and pivoted to the frame upon the forward axle ;
substantially as described.
2-In a wagon of the class described, the combination with the encircling
annular plate, J, of the pivoted bars, k, k², supported from the front axle and
provided at their ends with rollers running upon the inner edge of the encircling
plate; substantially as described..
3-The combination with the frame of a wagon, of a suitable block or abutment
upon the forward portion thereof adapted to be pressed against by a horse in
backing the wagon; substantially as described.
4-The combination with the frame of a wagon of a suitable block or abutment
supported upon the forward portion thereof and adjustable thereon, said block or
abutment being adapted in form to be pressed against by a horse in backing the
wagon; substantially as described.
5-The combination with the wheels and axle of a wagon, of a vertical pin
extending upward from the axle and secured thereto, and a box pivoted upon said
pin substantially as described.
6-The combination with the wheels and axle of a wagon, of a screw-threaded
pin extending upward from said axle and rigidly secured thereto, a hollow screw
internally threaded upon said pin and provided with means for turning it upon the
latter, and a box carried upon said screw by means of a nut secured to the box
and threaded to the exterior of the screw; the threads upon the interior and
exterior of the screw being cut in opposite directions, so that when the screw is
turned in the direction to raise the box upon itself, it raises itself upon the pin.
