Complete Specification Accepted, 16th Nov., 1888
1 ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
M.I.M.E. do hereby declare the nature of this invention to be as follows:-
The present invention relates to improvements in umbrellas and consists in replacing
the silk or cotton cover hitherto used by a cover of india-rubber coated' fabric or even
by pure india-rubber in one single piece.
The cover may consist of a certain number of triangular pieces of india-rubber
coated fabric which are either cemented or sewn together immediately above the ribs
of the umbrella and the joints or seams are hidden and rendered water-tight by india-
rubber strips which are cemented over them and are provided with imitation stitches
for ornamentation. The free side of each of these pieces is hemmed by an india-
rubber strip cemented thereon to prevent tearing.
The cover is fastened to the ribs of the umbrella frame which is of the usual kind
by means of small loops sewn to the latter or by a strip which runs along the seam
and forms so to say a sheath for the rib which it entirely covers.
The cover may also be of a single piece of pure india-rubber. The edges of this
cover are bound with a strip cemented thereon and the centre is provided with a disc
of canvas or equivalent strengthening material to prevent the metal of the frame
from injuring the india-rubber. Small triangles of canvas are also fastened to the
points of the cover where the latter is fastened to the points of the ribs which are
fastened to the cover by india-rubber loops cemented thereto.
