AN IMPROVED FASTENING FOR DRIVING BANDS, OR BELTS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I GEORGE ROBSON of 33 Dobson Street, Cambridge Street City and County of
Newcastle on Tyne Engineer & Millwright do hereby declare the nature of my
invention for AN IMPROVED FASTENING FOR DRIVING BANDS, OR BELTS to be
as follows:-
It is composed of Gutta Percha and Moulded or Compressed into Shape as shown
in Section at d, Each end of the Band or Belt is holed with a sufficient number
of holes to equal the strength of the Belt and Countersunk to suit the Heads of the
Fastening, the Band or Belt is now_placed in position on the Machine, or Lathe, or
where it may be required, the Ends are now overlapped and the Fastenings
inserted into the Holes, the Ends of the Band or Belt are now firmly Compressed
together at each Fastening by the nessasary Tool as shown in Section, care must be
taken to compress the Band or Belt together by the External Screw first, so that a
Mould will be formed by the Upper and Lower Dies and Material of which the
Band or Belt is composed, the Fastening is now firmly compressed into the proper
shape by the Internal Screw.

Engineer & Millwright, do hereby declare the nature of my invention for AN
IMPROVED FASTENING FOR DRIVING BANDS, OR BELTS and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
5
The Fastenings are composed of Gutta-Percha, and Moulded into shape as shown
in Section at D, as Cylindrical, or an End Section of which may be Oblong, or
Oval, proper Moulds and Dies, being made as required, the Ends of the Band or
Belt, are overlapped, and Holed to Templets, supplied by myself, the Holes are
not to be cut and Countersunk by a sharp cutting Tool, but Punched through by 1
the internal Punch I, and compressed by Conical Dies, to form the Countersink,
the Dies G, & H, being removed for that purpose, where Cotton, Hemp, or other
composition Belt, is used a Conical pointed Punch, is inserted instead of the
Punch I, so that the Threads are not cut, the Fastenings being now inserted
into the Holes, the Belt is firmly compressed together between the Dies G, & H, 1
the internal Punch I, being kept clear of the end of the Fastening while doing
so, a Mould will now have been formed between the Dies G. & H. and the material
of which the Belt is composed, the Fastening is now compressed into the finish'd
shape as shown in Section at B.
A, Section of Frame of Tool, for compressing Fastenings.
B, Fastening in complete state.
C, Fastening in process of being compressed.
D, Section of Fastening when first Moulded.
E, F, Cross Section of the Ends of a Band or Belt, which are overlapping each other.
G, H, Section of Dies, shown as Circular but which may be Oblong, or Oval.
I, Internal Screw Punch.
J, External Screw Press.
Its advantages, are that either side of the Belt can be run next to the Sheave,
without damage to the Joint. A Tension Sheave may be run on the back of the
Belt, with the same facility as a Hand Sewn Joint It is superior to a Joint of
Leather Lace, Clam Bolts, Hiuges, or Clips, as should they become turned over
with the wrong side to the Sheave, they are quickly destroyed or in the case of a
crossed Belt shorn off There is no danger of the Workmans Hand being cut or
injured by it, when catching hold of the Belt while in motion, to change it from
one Step of a Cone, to another, the Joint can be quickly separated, to readjust the
Belt to any required length, by inserting a Knife between the material, and cutting
the Fastenings through by the middle without damage to the Belt, the Fastenings
will not cut or decay the material of which the Belt is composed, as is invariably
done by a Copper Rivet, the Tool required being light, a Workman can ascend to
the top of a Ladder and form a Joint, with the same ease as a Laced Joint, one
half the length of overlap being required, the Sectional area of the Joint being
increased to bear a Tensile Strain, and no part of the Fastening coming in contact
with the Sheave, except the Head, its durability is insured as long as any other
part of the Belt
