PROVISIONAL SPECIFICATION.
Improvements in Shoes for Skidding the Wheels of Road Wagons
or Lorries.
I MICHAEL MOORE HOBSON, of Catchgate, Lintz Green, in the County of
Durham, Miller, do hereby declare the nature of this invention to be as follows:-
My invention has for its object to provide an improved road wagon or lorrie shoe
to more effectually give lateral gripping power on roads more especially during
snow and ice, by fitting longitudinally one or more iron, steel or metal plates at
right angles or other angle to the bottom of the shoe, and to convert the said shoe
to answer the same purpose as ordinary shoes; by making the plates dovetailed or
at such an angle as to receive and hold a plate or plates also dovetailed on or
between the former plate or plates thus making the bottom like an ordinary shoe.
The onward motion of the wagon and the friction on the road keeps the plates
firm in the dovetail.
Dated this 7th day of October 1891.
COMPLETE SPECIFICATION.
Improvements in Shoes for Skidding the Wheels of Road Wagons
or Lorries.
I, MICHAEL MOORE HOBSON of Catchgate, Lintz Green, in the County of
Durham, Miller, 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 has for its object to provide an improved road wagon or lorrie shoe
to more effectually give lateral gripping power on roads more especially during
snow and ice, by fitting longitudinally one or more iron, steel or metal plates at
right angle or other angles to the bottom of the shoe, and to convert the said shoe
to answer the same purpose as ordinary shoes, by making the plates dovetailed or
at such an angle as to receive and hold a plate or plates also dovetailed on or
between the former plate or plates thus making the bottom like an ordinary shoe.
I will describe my invention with reference to the accompanying drawings
wherein―
Fig. 1. is a side view of a shoe with one of my device applied thereto, ▲ shewing
the former and B the latter with a gap C in it to form the heel D which is to
prevent the shoe from slipping in front of the wheel when first entering the shoe.
When the vehicle moves forward the plate B cuts a groove in the ice to run in thus
preventing any lateral movements.
Fig. 2. shews a cross section of the shoe A with one plate dovetailed and section
of convertion piece E with a dovetailed groove to admit the former plate and hold
the same.
The groove may have an end in it to prevent the convertion piece from
slipping off or may be tapered from end to end so as to tighten as it is put on, or as
the friction on the road effects it.
Fig. 3. shews a cross section of a shoe A with a section of the convertion piece F
between two plates G only one side of those dovetailed to admit and hold F dove-
tailed on the outside. To prevent F from slipping off, the pieces G may be closer
to each other at the heels forming a taper, or may have projections on the convertion
piece F to catch G thus preventing its slipping between.

page_text: 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.―
First: One or more plates B or G with or without the gap C constructed in one
piece and fixed to A substantially as herein before described and illustrated in the 6
accompanying drawings.
Second: The convertion pieces E or F as hereinbefore described and illustrated
in the accompanying drawings.
