Improvements in Attaching and Detaching Projections to the Driving
Wheels of Traction Engines and the like, for Preventing Slipping.
I, SAMUEL GRAHAM, of 53 Esk Street, Invercargill in the Colony of New
Zealand, Farmer, 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 object of this invention is for the better securing when needed and the
detaching when not required, of those plates of metal that are fixed outside the
rims of the wheels of traction engines when used in soft or muddy places and
which I call mud climps or spuds. There are small ones that are permanently
attached to wheels, but my invention relates more to those that are larger and
more effective and which have to be often removed. The method at present in
use for this purpose consists of bolts that often work loose and the result is that
frequently both the bolts and climps are lost, or occasion delay in being refixed,
and the fixing and detaching of these climps and bolts not only takes much time
but results in many of the smaller parts being mislaid.
To obviate this I reduce the number of loose pieces to a minimum, thus reducing
the chances of loss, and most of my parts are fixed to the wheel of the machine. .
Referring to the accompanying drawing,
Figure 1 is a section of the tire and flange of one of the driving wheels of a
traction engine with my invention shown securing the climp.
Figure 2 is the same tire and flange with the climp and climp-bolt removed,
showing the parts that intend to remain in the wheel, pulled clear of the
climp-bolt and so held by the catch.
Figure 3. Is a side view showing the arm or projection secured in the catch.
Figure 4. Is the same with the arm released from the catch.
A is a bolt capable of sliding through convenient parts of the flange or spokes
of a wheel, the end of which projects so as to pass through and so secure one of
the bolts E. Each bolt A, ends in a convenient bend or handle, B, for working
same in or out of E.
C, is an arm or projection working in a catch such as shown at D for securing
the bolt A, away from E, when securing or loosening the same.
Fis any spring for keeping the bolt A, in the normal position as shown in
Figure 1. Any convenient form of spring may be used, or such as is shown.
G is a washer (when same is required) or the arm C, may be spread to a similar
form as thought best, for taking the pressure of the spring F.
His a mud climp or spud of any convenient section, and I, I, show the tire and
flange towards the spokes, of such a wheel as is being described.
In working, either in taking a climp or spud off or placing it on the bolt A,
is moved by B to the position shown in Figure 2, and the bolt E, is then free to
be taken out or put into its place to secure one end of the climp H, the other end
is secured by being turned or clipped over the rim or tire I, as shown. The
pin E may be of convenient section but I prefer it to be square so that the hole
comes opposite the end of the bolt A, with greater certainty.

page_text: Any required number of climps, and consequently of sets of bolts as here
described, may be used in each wheel.
Any suitable sizes or materials may be used in any part 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
In the driving wheels of traction engines and the like provided with removeable
plates for gripping and preventing the wheels from slipping in muddy or soft
places, the combination of such wheels with spring bolts (such as A. B.) capable
of being secured back out of the way and of securing the said plates or climps
by passing through bolts (such as E) and the arrangement (such as C, D, E, F Ġ)
all substantially as described and explained and as shown on the drawings.
Dated this 28th day of June 1897.
SAMUEL GRAHAM.
