PROVISIONAL SPECIFICATION.
Improved Foot Ball Cover.
I, DAVID NELSON, Kingswear, Devon, Diver, do hereby declare the nature of
this invention to be as follows:-
An improved foot ball cover made from canvas calico felt yarn leather or any
suitable materials either woven twisted or knitted I prefer calico thoroughly
impregnated with any suitable adhesive waterproof preparation I find india rubber
dissolved with any of its well known solvents with the addition of any suitable
colouring matter or vulcanizing agents answers well I take the prepared calico and
cut into parts of any suitable shape which when put together will form shape of
foot ball cover either round or oval I have moulds made from wood or other
suitable materials I find brass answers well I make moulds plain or with any
desired pattern on them I make the moulds in any suitable number of parts of any
suitable size and prefer making with three parts which I find forms a nice shaped
ball I take the parts of mould and give one or more coats of the prepared water-
proof material and proceed to place the prepared calico on moulds I lay flat and
stretch out smooth over mould I put several plies on top of first picce until I have
formed the desired thickness. I roll or press all together or
may use leather in
place of the woven fabric. If so I thoroughly clean mould and take any suitable
leather I prefer calf skin either shaved or split which has only been through the
tanning process and freed from all oil or fat or any foreign matter I steep in
water and cut into parts allowing for seams I place on moulds and rub smooth all
over and roll or press and cover with calico and fasten over moulds when dry
I roughen flesh side and give several coats of the preparation I may further cover
any suitable lining with the waterproof preparation and place over leather or
several plies leather until I have desired thickness I may further vulcanize in any
convenient way well known to manufacturers of india rubber I trim the edges the
size and sew or stick together in any convenient way I make welts from any
suitable waterproof material I prefer tubing made from india rubber about one
quarter of one inch diameter and sew between leather. I roll or press seams and
form two holes at ends where seams has left off at and insert flat buttons and
cover over with leather or india rubber I finish in the usual way and insert foot
ball bladder inside and blow up with air in the usual way and tie and lace I give
extended ball several coats of the waterproof material and have yarn either twisted
woven or knitted and waterproofed with the waterproof material and wind round
the extended ball a number of times several ways until I have added more strength
to ball cover I roll or press together and let air out from rubber bladder turn the
cover and finish in the usual way which will give me a nice shaped ball cover
which will keep the shape.

I, DAVID NELSON, Kingswear, Devon, Diver, do hereby declare the nature of
this invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-

page_text: suitable materials either woven twisted or knitted I prefer calico thoroughly
impregnated with any suitable adhesive waterproof preparation I find india rubber
dissolved with any of its well known solvents with the addition of any suitable
colouring matter or vulcanizing agents answers well I take the prepared calico and
cut into parts of any suitable shape which when put together will form shape of
foot ball cover either round or oval. I have moulds made from wood or other
suitable material. I find tinned brass answers well, make moulds plain or with any
desired pattern on them, make the mould in any suitable number of parts and any
suitable size but prefer making them in three parts which forms a nice shaped ball.
I take the parts of mould and give one or more coats of the prepared waterproof
material and place the prepared calico on mould lay it flat and stretch out smooth
over moulds put several plies on top of first piece until I have the desired thickness
roll or press together. I may use leather (2 or more plies) instead of woven fabric,
if so, I thoroughly clean mould and take any suitable leather, prefer calfskin either
shaved or split which has only been through the tanning process and freed from oil,
fat or any foreign matter, steep in water and cut into parts allowing for seams,
place on mould and rub smooth all over, roll or press, I roughen flesh side and give
several coats of the waterproof preparation. For welting, I cut thin leather into
strips about five eighths of an inch wide, coat same with the waterproof preparation,
put length of wire or cord in middle of it then double over leather, leaving wire or
cord in, which is cemented together by the waterproof material. When dry I
withdraw wire or cord, which leaves one leather tube with flange to sew between
the parts of material forming the football cover the tube part is heated & pressed
which gives the welt a T shape thereby protecting the stitches. I finish in the
usual way, insert football bladder, inflate lace and tie and have now a most
endurable football cover.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. Moulding into shape calico leather or other fabrics.
2nd. Waterproofing same either before or after moulding.
3rd. Placing together same to form football cover.
4th. Improved welt to protect stitches.
