We CLEMENS WEAVER, of Easton, Pennsylvania, United States of America,
Engineer, and THOMAS PAUL DUNN, of 65 Fulton Street, Pittsburg, Pennsylvania,
United States of America, Engineer, do hereby declare the nature of our said
invention to be as follows:-
The object of our invention is to provide an improved description of covering or
coating for the peripheries of driving pullies; also improved means of attaching
the same to the pullies, and rendering the same waterproof.
In carrying out our invention, we first apply paper, in one, two or more layers.
If the pulley is not sufficiently convex, the necessary convexity may be supplied
by reducing the width of the successive layers. Brown paper of good quality is
preferred, but other suitable kinds of paper may be used.
We use a special kind of cement for causing the paper and other materials
to adhere to the pulley, which cement consists of the following ingredients and
proportions:-
1 pound of flour.
12
a pound of glue.
an ounce of borax.
an ounce of alum.
2 ounces of isinglass.
an ounce of sal ammoniac.
These materials are boiled together and well-mixed.
In some cases the coating of paper will suffice for the purpose, but where a
stronger surface is required we lay and attach a covering of cloth, or other woven
fabric, upon the paper, which is caused to adhere to the paper by means of the
aforesaid cement.
:
We next prepare and apply a coating of waterproofing material, consisting of
crude rubber dissolved in glycerine. This coating soon becomes dry, and renders
the whole covering firm and binding; and capable of transmitting or receiving the
power carried by the belting without slipping.
It will thus be understood that our invention consists of the application to
driving pullies of paper; or paper and woven fabric; or paper, woven fabric, and
waterproofing; which materials are attached to the pullies by our improved
cement, before described.

Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. The method of covering or coating the working surfaces of driving pullies,
with paper, substantially as herein before described.

with paper and woven fabric, substantially as herein before described.
3. In covering or coating the working surfaces of driving pullies as aforesaid,
the addition thereto and application and use of waterproofing materials, sub-
stantially as herein before described.
4. In carrying out the aforesaid method and means of covering or coating the
working surfaces of driving pullies, the application and use of the improved
cement for the purpose of causing effective adhesion, substantially as herein before
described.
5. The application and use of the several materials ingredients and mixtures,
together constituting our improvements in the method and means of covering or
coating the surfaces of driving pullies, substantially as herein before described.
