is fastened is preserved. 2nd. Moisture or wet is prevented from touching the
sole of the boot or shoe which is at a height of from 20 millimetres (about 3/4 of an
incb) to 25 millimetres (about 1 inch) from the ground. 3rd. The wearer is
enabled to walk on ice or the most slippery pavements or roads without fear of
slipping. 4th. It prevents mud from being thrown up on to the trousers or dress

foot is placed on the patten, and a spring hinged to the heel piece of the patten
is turned so as to bear on the back of the boot or shoe, the top ends of the spring
being provided with an elastic, leather, or other strap which passes round the top
part of the boot or shoe, as shown in Fig. 1 in the accompanying Sheet of Drawings.
Figs. 12, 13, and 14 show details of two different forms of straps for this purpose.
The patten is made adjustable so as to adapt itself to different sized boots or
shoes, for which purpose it is made in two pieces, the heel piece being secured to
the sole piece by means of a bar forming part of the heel piece, the inner end of
the bar being provided with a series of holes and entering into a socket on the
sole piece. A screw passing through a hole in the socket secures the two pieces
together by passing through one of the holes in the said bar; Fig. 5 is a plan of
the two pieces joined together; Fig. 6 is a plan of the heel piece with its bar;
Fig. 15 is a side elevation of the same showing the spring hinged to the heel piece
turned down; Fig. 8 shows a front view of the hinged spring; Fig. 10 is a side
elevation of the heel piece; Figs. 7 and 9 show respectively the screw for securing
the heel and sole pieces together, and the pin to form the hinge of the spring fixed
