Improved Method and Devices for Securing and Fastening Roofing
Slates and Tiles.
I, ARTHUR READ POLLARD, of 18 Warwick Place, Worthing, in the County of
Sussex, Master Sign Writer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to roofing tiles and slates, and consists in an improved
method and devices for securing the same in position. It presents the following
advantages; that no holes need be bored through the slates except in the first courses,
and the end slates of each of the other courses; the slates or tiles when once fixed
are perfectly secure, and the projecting parts of the roof are not of a character to
injure the persons or garments of workmen employed on the roof, even if they slide
down upon it.
The improved devices consist of a locking strip, the upper end of which is nailed
or otherwise fixed to a batten, and which strip is covered by the slate, except at its
lower end, in which a slit or slot is formed of such a size that the web of a clip can
enter it. The flange or flanges of the clip are disposed underneath the slates with
the web projecting upwardly through the slit in the locking strip. A notch is formed
in the web into which the lower edge of a slate enters, and the point of the clip
above the slate being hammered or bent down the whole is fixed firmly in
position.
The clip and locking strip are made of metal or other suitable material which can
be bent.
The method of using these devices is as follows:-A row of slates having been
placed in position, the locking strips are nailed or otherwise fastened to the batten.
The web of a clip is inserted between the joint of two slates and slipped up,
with the flanges underneath the slates, until the lower edge of the slate above it is
reached. The slotted end of the clip having been bent up, the notch in the clip
engages with the slate edge and the end of the strip is bent down so as to allow the
slit or slot to pass over the web of the clip. The locking strip end is thus brought
flat and close to the slate, the point of the clip is bent down and the whole is fixed
firmly.
In some cases instead of slipping the web of the clip up between two already laid
slates, the clip is placed in position with one flange under a slate, and then the next
slate is laid to cover the other flange.

Improved Method and Devices for Securing and Fastening Roofing
Slates and Tiles.
I, ARTHUR READ POLLARD, of 18 Warwick Place, Worthing, in the County of
Sussex, Master Sign Writer, 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 roofing tiles and slates, and consists of an improved
method and devices for securing the same in position. It presents the following
advantages; that no holes need be bored through the slates except in the first courses,
and the end slates of each of the other courses; the slates or tiles when once fixed
are perfectly secure, and the projecting parts of the roof are not of a character to
injure the persons or garments of workmen employed on the roof, even if they slide
down upon it.
In order that my invention may be fully understood and ascertained I append
drawings in which:-
Fig. 1 is a plan of a portion of a roof shewing the device in three stages of
fixing.
Fig. 2 is a plan.
Fig. 3 is an end elevation, and
Fig. 4 is a side elevation of a clip as used.
Fig.
5 is a view of a locking strip.
Fig. 6 is a modified arrangement adapted to new slating.
Fig. 7 is a vertical section on the line of Fig. 6 on an enlarged scale, and
Fig. 8 is a plan of the clip when adapted to broad guage slating.
In Fig. 1a number of slates A are shewn placed in the usual well known manner
so as to overlap and break joint. They are arranged in the same relation as shewn,
to the batten B, and the locking strips C are of such a length that they can be
fixed or fastened to the batten at a point c which is near the nails c¹, by means of
which the slates are attached to the batten. The lower ends of the strips C (which
may be of any suitable material) have slits or slots c2 formed in them of such a size
that the vertical member or web of the clip can enter the same. The clip D is
composed of a web d and two flanges d¹, and may be cast or otherwise formed in any
convenient manner, and of any suitable material, but is shewn as bent up from one
sheet of metal, the weh d being of two thicknesses of the same plate as the
flanges d¹.
It has a notch cut from it so as to leave a point d³ which can easily
be bent down as shewn in dotted lines in Fig. 4.
The Fig. 1 shews a portion of a slated roof with one slate detached and also
shews the method of securing the slate to be replaced in three phases; the left
hand strip C is shewn fixed to the batten B, and the clip D inserted between the
joint with the flanges underneath the slates A, the centre strip is shewn fastened
with the slate replaced and the strip bent up with the clip D inserted in the slit c²
the right hand strip C is shewn bent down over the clip D, the point d is hammered
or forced down, thus the slate is securely replaced.
The slates are fixed in position by means of the clips and strips in the following
manner-
A row of slates having been fixed in position a locking strip is fixed or fastened to
the batten B as shewn. The web of a clip d is inserted and slipped up the joint
between two slates, the flanges being underneath these, as shewn in Fig. 1. The
next slate is then placed in position; and the end of the strip C being turned up,

page_text: the clip D is pushed up against the edge of the slate so that the latter enters the
notch. The end of the strip C is then turned down over, enclosing the web d
of the clip D. and the point d is hammered or otherwise forced down
slate: thus the whole is fixed firmly and rigidly in position.
In Fig. G the slates A are shewn placed in the ordinary manner for new slating,
that is when they are fixed in succession from the eaves upwards. The first and
second row of slates are placed in the usual manner to overlap one another and are
nailed or secured to the roofing battens B by nails, screws, or other suitable device,
at points . The clips D are placed in position along the first row of slates during
the operation of securing the second row. The locking strip C is then secured to
the next slating batten in the manner described in Fig. 1, and the slot c² is passed
over the vertical web of the clip D. The next slate above can now be placed in
position overlapping the joints of the slates underneath in the ordinary manner.
The bottom edge a of the slate A now rests in the notch of the clip, and the point ³
of the clip D is hammered or forced down in such a manner as to firmly hold the
slate in position. Another clip D is now placed with one flange under the slate in
a position to receive the bottoin edge of the next row of slates, and the next slate
is placed to overlap the other flange of the clip and is secured in the manner already
described above. The locking strips are now secured between the points of the two
adjacent slates to the batten next above, and the slots passed over the web of the
clip D, these being now ready to receive the next row of slates. The operation is
then continued in this manner till the whole of the required slating is finished. The
corners of the flanges d¹ of the clip D may, if preferred, be rounded. The top
edge of the web d of the clip, including the point d³, may be formed with a bead
if preferred as shewn in dotted lines Fig. 3.
In broad guage slating the clip D is made with right handed or left handed
flanges d as required; Fig. 8 shewing a left handed clip,
By this method the slates or tiles may be fixed firmly upon a roof in a simple
and economical manner, while securing all the advantages set forth in this
specification.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that
what I claim is :-
1. The method of securing and fastening roofing slates and tiles in position,
substantially as described.
2. The method of securing and fastening roofing slates and tiles in position,
which consists in slipping a clip between the edges of two already fixed slates or
tiles; bending over it the slotted part of a strip, the upper end of which is fixed to
the butten above; and then bending or forcing down the point of the web of the
clip, substantially as described.
3. The method of securing and fastening roofing slates and tiles in position
which consists in fixing the clips in position with their flanges underneath adjoining
slates in the same row; then passing the slit of a locking strip over each of the webs
of the same, then fastening the upper end of the locking strip to the batten
above and forcing down the point of the clip upon the slates, substantially as
described.
4. For use in securing and fastening roofing slates or tiles, a clip consisting of a
web d, and one or two flanges d', the web having a noteh d2 formed in it in such
manner that a point is left which can be hammered down upon the slate,
substantially as shewn and described.
5. For use in securing and fastening roofing slates or tiles, a strip having a nail
or screw hole in one end, and a slit or slot in the other, end, substantially as
shewn and described.
6. For use in securing and fastening roofing slates or tiles, the combination of a
clip D, the web of which has a notch de formed in it, with a strip C having a slit or
slot c² of such shape and size that it fits over the web d of the clip D in such manner

page_text: that the point d³ can be bent down upon the slates, substantially as described and
shewn.
