Liverpool, in the County of Lancaster, for the Invention of "AN IMPROVED
SLIDING STUD FOR FASTENING ZINC AND OTHER METAL SHEETS SO AS TO
ALLOW FOR EXPANSION AND CONTRACTION."
Sealed the 19th December 1876, and dated the 24th August 1876.
PROVISIONAL SPECIFICATION left by the said Charles Fredrick Elliott
and John Bayley at the Office of the Commissioners of Patents on the 24th
August 1876.
CHARLES FREDRICK ELLIOTT and JOHN BAYLEY, both of Liverpool, in the
County of Lancaster. "AN IMPROVED SLIDING STUD FOR FASTENING ZINC AND
OTHER METAL SHEETS SO AS TO ALLOW FOR EXPANSION AND CONTRACTION."
Our Invention relates to a novel form of stud, which is so constructed as to allow
for any expansion or contraction that may take place in zinc and other metal
sheets or plates when used for roofing and other like purposes, and consists in
forming the stud with a base plate, on which it is freo to slide. This is effected by
forming the base plate with a. slot, through which the stud is passed; the stud
having a head under the plate and a fixed washer over the plate so arranged that
the stud is free to slide the length of the slot
In the case of screw studs the stud is provided with a nut or cap, which screws
on, so that when in position the nut holds the sheet to be fastened firmly to the
base plate before mentioned, which plate is fixed by means of screws, or otherwise,
to the main structure, being the purlins, boarding, rolls, or framework. The zinc
or other metal sheets are thus fastened, and at the same time the sliding stud
allows for any expansion or contraction that may take place from variations of
temperature, or otherwise.
Our improved stud is adapted for fastening all kinds of metal sheets or plates
subject to expansion or contraction, and is particularly adapted to be used in
connection with certain improvements in fixing plates or sheets of metal, for
which Letters Patent were granted to G. Dibley on the 26th January, 1865,
No 232.

and the sheet is held to the roll, and at the same time the fastening stud A is free
to slide in the slot C, and thus allows for expansion and contraction of the zinc
sheets L. Each alternate fastener may be fixed as at O, Figure 6.
Although we have only illustrated our Invention as applying to zinc roofing
we would have it understood that our improved stud is adapted for fastening all
kinds of metal sheets or plates subject to expansion or contraction, and is par-
ticularly adapted to be used in connection with certain improvements in fixing
plates or sheets of metal, for which Letters Patent were granted to G. Dibley, on
the 26th day of January, 1865, No. 232.
It will be obvious also that our improved sliding stud can be used for other
fastening purposes and can be applied to other materials than zinc sheets.
That our improved stud may be known we have named it "the Nonpareil
Sliding Stud."
Having now described and particularly ascertained the nature of our said Inven-
tion, and the system, mode, or manner in or under which the same is or may be used
or practically carried into effect, we would observe in conclusion that what we consider
to be novel and original, and therefore claim as the Invention secured to us by
Letters Patent as aforesaid is,―
Firstly. The improved sliding stud (for fastening zinc or other metal sheets,
or other materials, so as to allow for expansion and contraction), consisting of a
stud, such as A, in combination with and sliding on a base plate such as B, and
provided with a nut, cap, or head, such as F, substantially as shown in the
Drawings and set forth in the before-going Specification.
Secondly. The method of applying the sliding stud, such as herein-before
described and illustrated, for fastening metal sheets, which are subject to expansion
and contraction, to roofing, as shown in the accompanying Drawings and set forth
in the before-going Specification.
In witness whereof, we, the said Charles Fredrick Elliott and John Bayley,
have hereunto set our hands and seals, this Eighth day of February, in
the year of our Lord One thousand eight hundred and seventy-seven.
