IMPROVED MANUFACTURE OF LATH BACKING FOR PLASTER WORK
Year: 1885

page_text: I HORATIO CLEAVE of 3 Cavendish Road, Aylestone Park, Leicester in the
county of Leicester, Commercial Traveller do hereby declare the nature of my
invention for "IMPROVED MANUFACTURE OF LATH BACKING FOR PLASTER WORK"
to be as follows:-
The object of this invention is to utilize strips of cheap wood to take the place
of expensive laths now used. By this method moreover a ceiling may be covered
ready for the plasterer in a much shorter time than is usually occupied.
It may be seen that laths usually split by "renders" present a polished surface
and being sometimes of great width there is frequently too great a space to form a
proper key to hold the plaster.
This method includes the use of sawn strips which present a rough and therefore
very suitable surface to produce adhesion and the strips being narrow a satis-
factory key for the plaster is given in less space than is usually occupied by the
lath.
By this process shrinkage of material is avoided and in case of vibration cracking
of the ceiling is prevented.
The strips of wood are preferably say three feet long and are bound together by
brass, iron or otherwise, or other, suitable binding so that there may be sufficient
room between each lath to afford good key space.
These laths may be bound together in suitable lengths or widths to suit the size
of any ceiling or the like for which it may be intended to use the same.
When produced the "mats" of laths are held to the space to be covered, placed
so that the ends cross the joists or pillars to which they are to be attached and
nails or hooks having T heads or otherwise suitably formed may be driven in at
convenient distances. This method shows. a great saving in nailing, time, and
material.
It is estimated that a ceiling may be covered in this way at half the present
price for ordinary lath work.

Improved Manufacture of Lath Backing for Plaster Work.
I HORATIO CLEAVE of Cavendish Road Aylestone Park, Aylestone, near Leicester
Timber Agent and Traveller do hereby declare the nature of my invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of the invention is to utilize strips of cheap wood to take the place
of expensive laths now used. By this method moreover a ceiling may be covered
ready for the plasterer in a much shorter time than is usually occupied.
It may be seen that laths usually split by "Renders" present a polished surface
and being sometimes of great width there is frequently too small a space to form a
proper key to hold the plaster,
This method includes the use of sawn strips which present a rough and there-
fore very suitable surface to produce adhesion and allow of a more satisfactory key
for the plaster than is usually given by the ordinary lath.
By this process shrinkage of material is avoided and in case of vibration cracking
of the ceiling is prevented.
The strips of wood are preferably say 3 feet long and are bound together by
brass iron or other wire or other suitable binding so that there may be sufficient
room between each lath to afford good key space.
The laths may be bound together in suitable lengths or widths to suit the size of
any ceiling or the like for which it may be intended to use the same.
"
When produced the mats" of laths are held to the space to be covered placed
so that the ends cross the joists or pillars to which they are to be attached and
nails or hooks having T heads or otherwise suitably formed may be driven in at
convenient distances. This method shows a great saving in nailing, time, and
materials.
It is estimated that a ceiling may be covered in this way at half the present
price for ordinary lath work.
Referring to the accompanying drawing A shows the laths lying parallel to each
other but with a suitable space between each lath.
These laths are bound together by brass iron or other suitable binding B prefer-
ably wire.
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 herein described lath backing for plaster consisting of a number of laths
or strips such as A of rough wood flexibly joined by wire or equivalent fastenings B

specified.
2. The method of forming a backing for plaster which consists in joining
together a number of laths or strips substantially in the manner and for the purpose
specified.
