An Improved Cart or Wagon for Lifting and Transporting Heavy
Articles or Objects.
A communication from CONRAD HEER, of 49, Maxfeldstrasse, Nürnberg, in the
Empire of Germany, Mechanician.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil Engineer 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 :-
The appliance shown in Figs. 1 and 2 of the accompanying sheet of drawings is
for lifting and transporting heavy articles or goods of various kinds and shapes, for
instance blocks for building purposes, caska, missiles, etcetera.
Fig. 1 is a vertical section and Fig. 2 a plan view of the improved cart or wagon.
The object of the invention is to do away with the difficulties and inconveniences
attendant on the loading or unloading of such kind of heavy goods.
The new or improved appliance is constructed as follows:-
A clamping appliance, resembling a pair of tongs, is connected with a two
wheeled cart or wagon in such manner that the levers a a, forming the jaws of the
tongs can turn on the cross bar g.
The continuations a¹ a¹, of these levers serve for handles when the appliance is to
be used, and as will be seen these handles are on the one side of the pivots 2 21
which form turning points. The short arms of the levers a a₁, on the other hand,
have at the front end checks or jaws b b₁ which may be of any suitable shape but
are preferably shaped to suit the kind of article which is generally to be carried by
them.
i
It will be understood that the weight is clamped in between these cheeks or jaws
and is then raised by depressing the levers a' a. In order that the article can be
seized and clamped, and finally deposited, by the cheeks or jaws, there is provided
a spindle c having a hand wheel 1, the screw m of the spindle is seated on the
framework of the cart or wagon. The front end of the spindle is connected with
the levers a a, by means of hinged braces d d₁ so that the levers a a₁ can therefore
be turned by means of the spindle c on the pins zz₁. The distance between
the jaws or tongs can therefore be increased or diminished according to the
direction in which the spindle is turned. In consequence of the great leverage
obtained by the spindle c and the levers d d₁ the weight 1, which in this case is a
building block, can be clamped fast between the jaws b b₁ with a comparatively
small expenditure of force, so that there need be no fear of the weight slipping in
course of transport.
With this new appliance a heavy weight may be clamped, raised and transported
by a single person without any other special appliance or tools being requisite
for these purposes.
In order to secure the utmost possible use of the same appliance when the
articles to be transported are of very varying sizes, the clamped pieces b b₁ may
be made adjustable in regard to the levers a a, so that in this manner also the
distance between the jaws may be increased or diminished.
This new appliance if necessary may be employed to take the place of a crane
for raising and transporting heavy articles, such for instance as parts of machinery.
The appliance is also suitable for carrying casting pots and similar heavy

page_text: vessels, the cheeks or jaws b b₁ being then suitably formed for taking hold of the
handles which are fastened to the pots.
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 :-
A cart or wagon for lifting and transporting heavy articles or objects of any
shape, having a pair of shafts which act as tongs (a a) mounted upon a portable
framework, the jaws bb₁ of which tongs, which grip the load, can be opened and
closed by means of the devices c d d₁.
