PROVISIONAL SPECIFICATION.
Improvements in Means for Securing Slates in Position upon
Roofs.
We ARTHUR CALVERT, of High Green near Sheffield in the County of York
Slater and WILLIAM DURANT of Chapeltown near Sheffield aforesaid Electrician
do hereby declare the nature of this invention to be as follows:-
This invention relates to means for securing slates in position upon roofs, and is
more especially applicable to where repairs are needed. Hitherto when replacing
or renewing a slate of a roof it has been usual to employ lead lugs or straps or
copper wire, and to fasten one end of same to the lath, and bend the lower end
in hook fashion to support the slates; this arrangement has not proved satisfactory
in-as-much-as the hooked end of strap being exposed may be easily bent back or
broken off by falling snow or wind, thus allowing the slate to become displaced, or
a slater or other person moving on the roof may easily displace such slates to his
danger; the object of our present invention is therefore to adapt a simple and
effecient device which when fixed to a slate, the said slate can be easily passed
under a remaining slate until it arrives at its required permanent position when the
said device automatically secures the slate in said position; to attain which we
employ a device composed of zinc, copper or other pliable metal, having two or
more projections extending. from a broader portion or base, the said projections
passing through suitable holes made in the slate and bent over so securing the
device to the slate. Underneath the broader portion or base we connect thereto by a
suitable joint a fall piece or catch or catches, or we fasten thereto a spring or
springs. As soon as the slate is placed to the required permanent position on the
roof, the said fall piece or catch drops by gravity at the top side of lath aud so
securely prevents the slate from falling or becoming displaced. In a similar way
the spring or springs will spring out so as to bear against the top side of lath and
so secure the slate in position.
'
:
We prefer to arrange the parts of the fall piece, catch or springs which bear
against the lath with teeth or serrations or other projections so as to enter the lath
for the better securing of the slate.

We ARTHUR CALVERT of High Green, near Sheffield in the County of York,
Slater, and WILLIAM DURANT of Chapeltown near Sheffield aforesaid Electrician
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:-
This invention relates to means for securing slates in position upon roofs and is
more especially applicable to where repairs are needed.

page_text: Hitherto when replacing or renewing a slate of a roof it has been usual to employ
lead lugs or straps or copper wire and to fasten one end of sanie to the lath and
bend the lower end in hook fashion to support the slates; this arrangement
has not proved satisfactory inasmuch as the hooked end of strap being exposed it
may be easily bent back or broken off by falling snow or wind or a slater on the
roof could easily displace the same by the pressure of his foot, the object therefore
of our present invention is to adopt a simple and effecient device which when fixed
to a slate, the slate can be passed under remaining slates and when in position the
said device will automatically secure the slate in position to attain which I employ
in combination with an ordinary roof slate a device substantially as described with
reference to the accompanying sheet of drawings which are to be taken as part of
this Specification and read therewith.
Fig. 1 is a side view of one form of my improved device fastened to a slate and
Fig. 2 is a front view of same.
Fig. 3 is a side view of another form of our improved device fastened to a slate
and Fig. 4 is a plan of same showing position of two devices on slate.
Fig. 5. is a side view of device fastened to slate and such slate placed in secured
position on roof and Fig. 6. is a plan of same.
'
Fig. 7. is a plan of slate having a modified form of device fitted thereto and
Fig. 8 is a cross sectional elevation taken on broken line a a of Fig. 7. and Fig. 9.
is a side view of same.
Similar letters of reference denote corresponding parts in each view.
Referring to Figs. 1 and 2 we employ a device B composed of zinc, copper or
other suitable metal having projections 6 extending from a broader portion 63 and
passing through suitable holes inade in the slate S and bent over as shown so securing
the device B to the slate S.
Underneath the broader portion 62 we swivel a fall piece or catch b³.
Referring to Figs. 3 and 4 the device B is made of a spring piece of metal 63
having a serrated end and it is bent as shown and fastened to the slate S by either
a solid or hollow rivet or eye b¹.
1
Referring to Figs. 7, 8 and 9. The device is arranged to clip the edge of slate S
by its extensions 6 and is rivetted thereto as shown, the fall piece or catch b³
extending near the outerside edge of slate.
As soon as the slate S is placed or forced to position required on the roof the
fall pieces drop by gravity or spring down onto the top side of lath L see Figs. 5
and 6 and so securely prevents the slate S from falling or becoming displaced.
We would have it understood that we do not confine ourselves to the particular
shape of the fall pieces or springs 63 illustrated as it will be obvious the same could
be modified in a number of ways and that therefore our invention consists
essentially in fixing to a slate S, a device [B part of which falls or springs to the
back of a lath L subsequent to the slate $ being forced or placed to position,
required on the roof.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. In means for securing slates in position upon roofs the use in combination with
an ordinary slate S of a device B part of which will fall or spring to the back of a
lath L upon the slate being forced to or placed in position required upon roof and
by bearing in or against such lath secures slate in position.
