Improved Asphalte for Filling the Joints of Setts and Paving, 80, as
to Prevent it from Melting with the Heat of the Sun and not to
be Brittle in Winter.
JAMES WETHERILL of No. 5 Healey-Road-Batley-late-Borough Surveyor of
Keighley Yorkshire now out of business'do hereby declare the nature of this
invention to be as follows:—
The asphalte is composed of pitch put into an ordinary tai boiler and when
melted creosote oil or coal tar is then added to it in such proportions that when
cold it shall be made tough and not brittle in any way, this is the ordinary way of
making asphalte. I then add one third in weight more or less as required of fresh
slacked lime that has passed through a fine sieve and thoroughly mixed together
boiling hot it is then ready for pouring into the Joints of the sette or paving filled
up flush to the surface this addition will be of great public utility in preventing
the asphalte fiom melting with the heat of the sun and not being brittle in
winter.

JAMES WETHERILL 5 Henley Road Batley Yorkshire late Borough Surveyor
of Keighley Yorkshue. I do hereby declare the nature of this invention and
in what manner the same is to bo performed, to be particularly described and
ascertained in and by the following statement:—
The quality of the pitch used must be first tested so that if one ton of pitch
takes twenty four gallons of creosote oil or forty eight gallons of coal tar more oi less
to make it when cold tough, and not brittle any way Then the following pro-
portions are to be used in iny improved asphalte as follows viz. for Yorkshne stone
to one ton of pitch of the above quality put into an ordinary tar boiler and when
nielted twenty gallons of creosote oil or forty gallons of coal tai more or less must
be added and four hundred-weight more or less of fine sieved fresh slacked line
well mixed together and made boiling hot it is then ready for filling the joints of
the setts or paving.
Foi gianite or whinstone one ton of pitch nineteen gallons of cicosote oil or
thirty eight gallons of coal tar more or less and four hundred-weight more or less
of lime. For cicosoted wood paving one tou of pitch seventeen gallons of creosote
oil or thirty four gallons of coal tar more or less and five hundred-weight moio oi
less of lime.
When the lime is mixed with pitch tar or creosote oil, by its action it provents
the asphalte from being soft in summer and brittle in winter.

page_text: Having now particularly described and ascertained the nature of my said invon-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The addition of fine sieved fresh slacked lime mixed with the pitch tar or
creosote oil in a boiling state so as to prevent it from melting with the heat of the
sun and softening the same in winter so as not to be brittle in any way.
2. The reduction of the quantity off creosote oil or tar used for softening the
pitch.
Dated this Thirteenth day of June 1895.
