PROVISIONAL SPECIFICATION left by the said John Edis at the Office of
the Commissioners of Patents, with his Petition, on the 22nd March
1864.
JOHN EDIS, of 146, Shoreditch, in the County of Middlesex,. Upholsterer,
do hereby declare the nature of the said Invention for "AN IMPROVED METHOD
or FASTENING TABLE TOPS WITHOUT THE AID OF THUMBSCREWS,'
to be as,
follows:-
The present method of fastening the tops of tables to the block is by means
of thumbscrews and a spring catch. This Invention consists of two metal
platės forming a lock, as shewn in the Drawing, namely, Figure 1, A, a metal
plate containing two apertures C, C; and Figure 2, B, another metal plate
containing two metal studs D, D. Figure 1 is fixed upon the block of the
table, and Figure 2 is fixed upon the clamp of the table top, the two plates
fitting together and fastening the table without the aid of screws, as shown by

FASTENING TABLE TOPS WITHOUT THE AID OF THUMBSCREWS," upon the condition
(amongst others) that I, the said John Edis, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.

NOW KNOW YE, that I, the said John Edis, do hereby declare the nature
of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained.in. and by the following statement
thereof, that is to say :-
The present method of fastening the tops of tables to the blocks is by means
of thumbscrews and spring catches so arranged as to admit of the tops of
tables being turned into an upright position, on the thumbscrews when the
spring catches have been drawn back or unlocked..
This Invention consists in the application of two metal plates forming a
lock, as shown in the Drawings hereunto annexed.

DESCRIPTION OF THE DRAWINGS.
One of these plates A is

a plan and edge view of the other of the two plates.
shown with a flange, but this may be dispensed with.
are formed with two sides or edges parallel, and one of the ends at right angles,
whilst the other end is curved or rounded off at one angle. It may, however,
be stated that the forms of these plates may be varied; and at Figures 3 and 4
plates A and B of a like kind are shown to be of a triangular shape, and the
plate A is made without flanges.

page_text: A and B, where there is only one aperture C and a recess C¹ therein to receive
the two studs D, D', carried by the plate B, whilst in each of the plates A
previously referred to there are two separate apertures to, receive like studs
D, D. Figures 7 and 8 show similar plates A, B, to those shown in Figures 5
and 6, but they are of a triangular form, and the plate A is without a flange.
Each of the plates B is shown to have two studs D, D', fixed thereto; the
larger stud D is, when applied to a table, to act as an axis when it is at the
lower end of the principal aperture C, whilst the smaller stud D' enters the
smaller aperture C¹ in the plate B, or it enters the smaller recess or aper-
ture C¹ which is formed near the upper end of the aperture C in the plates A
in Figures 5 and 7, where the two apertures are combined together and not
separate one from the other, as in Figures 1 and 3. Two pairs of these plates
A and B are used to each table, and they are respectively fixed at two angles
of the rounded back edge of the block of a table, as will be understood by
reference to Figures 9, 10, 11, 12, and 13, where two blocks E and tops F of
two tables are shown. In Figures 9 and 10 the plates A and B of Figures 1
and 2 are shown affixed; and in Figures 11, 12, and 13 the plates A, B, of
Figures 7 and 8 are shown; but whatever be the forms or shapes of the
plates, in each case in one there is a suitable aperture or opening C to receive
the principal or larger stud D, which forms one of the axes on which the
top F of the table turas when raised from the horizontal into the upright
position.
Having thus described the nature of the Invention, and the manner of
performing the same, I would have it understood that what I claim is, the
combined arrangement of the parts A, B, C, D, as herein described.
In witness whereof, I, the said John Edis, have hereunto set my hand
and seal, this Twentieth day of September, in the year of our Lord
One thousand eight hundred and sixty-four.
