Improvements in Mud Guards for Pneumatic and Solid Rubber or
Composition Tyres.
We, SAMUEL DUNLOP, Blacksmith, and GEORGE HENRY OATWay, Merchant,
both of 31, Moray Place, in the City of Dunedin, in the Colony of New Zealand,
do hereby declare the nature of this invention to be as follows;—
Our invention relates to an improved appliance for scraping and deflecting
mud, water, sand or the like from the tyres of wheels, and from a point near the
ground. The scraper is held in position by rods or tubes on each side fixed, to
a suitable part of the frame and it is preferably resilient.
Referring to the accompanying drawing:
Figure 1, is a general view of the appliance in position.
Fig. 2, are various details being a plan and side view of the appliance with
some methods of obtaining suitable adjustments of the scraper.
;
Fig. 3, is a brush scraper either an ordinary brush or the scraper may be split
to the form shown, to the outline of wheel in all cases.
Fig. 4, is a hard scraper yielding to inequalities by springs, as shown.

do hereby declare the nature of this invention and in what manner the same is
[Price 8d.1

page_text: to be performed to be particularly described and ascertained in and by the
following statement:-
Our invention relates to an improved appliance for scraping and deflecting
mud, water, sand or the like from the tyres of wheels and from a point near the
ground.
:
The scraper is held in position by rods or tubes, preferably, one on each side,
fixed to a suitable part of the frame, body or axle carrying the wheels, and is
adjustable as to its distance from the tyre, and is preferably resilient.
The adjustments may be in the rods, scraper or both.
Referring to the accompanying drawing; and also to the drawing lodged
with the Provisional Specification:-
Figure 1, is a general view of the appliance as fixed to any wheel, a part of
such wheel being shown.
Fig. 2, are details of construction, and consist of a plan of the appliance with
a side view of same and some methods of obtaining suitable adjustment of the
scraper.
Fig. 3, is a brush form of the scraper and is either an ordinary brush or the
scraper may be slit approximately as shown and in all cases it is made to con-
form to the outline of the tyre.
Fig. 4, is a non-resilient form of scraper which has an adjustment of springs
to yield to the tyre as required by inequalities of pressure. Fig. 5, is a spring
tilting adjustable scraper. A, is the scraper, A¹, is the part of same projecting
behind as an apron, to deflect the intercepted substances to the ground. A", is
the brush form of same. B, B, Fig. 2, are slots in the scraper A and B° 1°
are pins on the supporting rods F the said pins engaging the slots B B and
allowing of adjustment of the scraper. In Figure 4, B', are springs in the
slots B for use with a hard scraper. C, is a right and left handed thread, and
hand nut adjustment and D), is a socket adjustment, both allowing of the
instant removal of the scraper. E, is an end fixing to the wheel spindle to fit
a square, E¹, is a slot adjustment to fit the same place, and E, is a collar to
secure to any part of the frame when greater rigidity is required. F, are various
forms of tubes or rods forming a frame for holding the appliance in place G, is
a swing scraper pivoted to the rods F and adapted to be adjusted to and held
at any angle by means of a screw engaging a slotted quadrant G₁; H, is a swing
scraper secured in position by a pin passing through a hole in the frame and
in the scraper. J, Figure 5, is a spring for normally holding the scraper when
of a swing form in a horizontal position, one end of the spring being attached
to.. the scraper and the other end to the frame F. The said spring may be of
any form for this purpose, K, Figure 5 is a lever cam pivotted to the frame F
for moving the scraper into the position shown on the drawing and thus remov-
ing it from contact with the wheel.
It is obvious that in these varieties the same object is intended, and any suit-
able materials or sizes may be adopted.
Having now particularly described and ascertained the nature of our said in-
vention what what manner the same is to be performed, we declare that what
we claim is :-
The combination with a pneumatic and solid rubber, leather, or composition
tyred wheel, of a scraper (such as A, A¹) or a scraper formed as a brush (such
as A, A¹) held by fixed or adjustable rods (such as F.) all substantially as
described and explained and as shown in the drawing.
