Improvements in Hay Cock Weather-shields.
We, JOHN ALBERT SYMMES, and LUTHER RICHARDSON SYMMES, both of the City of
Sherbrooke, in the Province of Quebec, in the Dominion of Canada, Wood Pulp
Manufacturers, do hereby declare the nature of our invention for IMPROVEMENTS IN
HAY COCK WEATHER-SHIELDS, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
Our invention has for its object to afford protection from rain to cocks of hay or
sheaves of grain in stacks, while in the field, and our invention consists of a concavo-
convex paper pulp shield, either radially crimped or plain, having eyelets near the
circumference and painted on the convexity or otherwise waterproofed to prevent
saturation by water, guy ropes knotted to the eyelets, and tent pegs attached to the
ropes, whereby the shield will allow circulation of air to prevent mildew, and shed
rain when placed on a cock of hay or stack of grain, and the ropes and pegs maintain
the shield in position to resist a storm.
Fig. 1 represents a view of our improved weather-shield corrugated, and applied to
a cock of hay, and Fig. 2 is a like view showing our improved weather-shield not
corrugated.
A, is a concavo-convex circular shield or cover molded from a sheet of paper pulp
by compression between dies after the sheet is taken in a soft or wet state from the
roll of the paper machine, and subsequently dried, whereby the shape of the mold will
be maintained. The shield or cover is then waterproofed or painted on the convex
surface to prevent saturation by water, and being molded to one shape will nest
together compactly for transportation, or stowage from season to season, and under
fair treatment will be durable for many years.
The dies may be of such form as to mold the shield whereby radial corrugations B
are formed as shown in Fig. 1, or the dies may be plain to make the surfaces of the
shield smooth or without corrugations.
When the shield is corrugated it may fit closely over the top of the cock or stack,
as the air will circulate through the corrugations not in contact with the hay.
When the shield is made plain or without corrugations, it should have less con-
cavity, whereby the edge of the shield will stand out from the top of the cock or stack

page_text: to allow air to circulate under the shield and prevent mildew attacking the hay or
grain.
C, are eyelets at suitable distances apart inserted near the circumferential edge of
the shield to receive guy ropes D, which are fastened to pegs E driven into the ground
to keep the shield from being blown off the cock or stack during a storm.
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. A shield, to place upon the top of cocks of hay, &c. for protection from the
weather, when made of a sheet of paper pulp, molded to concavo-convex form, and
corrugated from the edge radially, as set forth.
2. A circular concavo-convex shield or cover made of paper pulp, as set forth.
3. A concavo-convex shield, constructed of a sheet of paper pulp molded in a moist
state between dies, and dried and waterproofed or painted on the outside, and provided
with holes near the circumferential edge, for the purpose set forth.
4. The combination of the concavo-convex paper pulp shield A, having eyelets C,
near the circumferential edge, guy ropes D, and pegs E, as set forth, for the purpose
described.
