Improvements in Extension Tables.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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:
The invention consists in the peculiar construction of the connection between
the leaves which are adapted to be stored in receptacles formed above the end
portions of the table, and in the construction, arrangement and combination of the
various parts.
In the accompanying drawing,
Figure 1 is a bottom plan view of my improved table, showing the table extended
and the leaves in position.
Figure 2 is a vertical section through the table showing it in the act of being
'closed.
Figure 3 is a detached, perspective view of a part of two leaves showing an.
enlarged view of the connecting strap.
Figure 4, is a vertical central section through the table showing it with the leaves
stored.
Figure 5 is a cross-section, and
Figure 6 is a longitudinal section showing a modified form of connection.
A and B are the two end sections of the table having the stationary slides C
and D. respectively, to which the movable slides Ę are connected.
The stationary slide C is provided near the end of the section A with an inclined
portion F which extends from the guide rail G at the lower edge of the section A
near the top of the table, as plainly shown in Figure 2.
The tops of the end sections are provided with outwardly flaring depending
flanges, H, within one of which is formed a storage receptacle I for the leaves J,
of a width greater than the width of the leaves, as shown in Figure 5.
The leaves when not in use are designed to be stored in the receptacle I and
when in use they rest upon the top of the slides E and are held together by the usual
dowel pins.
In the drawing, I have shown two sets of leaves ab arranged in tiers, one above
another in the receptacle. It is evident, however, that one set alone may be used
where a shorter table is desired. Each set comprises two leaves connected
together and the connection between these leaves consists of a leaf spring K secured
at one end fixedly to one leaf and at the other end provided with a slot L
through which a large headed screw M engages, whereby a substantially rigid
connection is had to allow a limited sliding movement of the leaf upon the spring.
This sliding movement is not necessary if the edges of the leaves are bevelled, as
shown in Figure 6.
The two sets of leaves are connected together by a flexible strap O. The upper
tier of leaves may be guided upon guides at the side of the receptacle, or any other

page_text: means may be employed to prevent their scratching the under leaves in moving
therein, such for instance as felt strips P on the under face.
The part being thus constructed and the table extended in the usual manner, as
shown in Figure 1, to close it, the edge of the first leaf is detached, allowing that
leaf to rest upon the incline F of the stationary slide C and pressure is now
brought at opposite ends of the table. The first set of leaves a will be forced down
the incline, the second one will follow it because the weight of the first leaf acting
through the spring K will tip the leaf as it comes to the edge of the incline.
The succeeding leaves of the set b will follow in the same manner moving upon
the top of the set a.
In drawing the leaves out the operator separates the two
end sections of the table and in doing so the leaves will be drawn from the recep-
tacle upon the incline F to the top thereof, by means of the flexible spring K¹
connecting the end section B with the leaf J, the operator then engaging the
dowels in the apertures provided for them the leaves will be held in line with the
top. After the first section is withdrawn the second section will be caused to follow
by the connecting strap O. The slot L in the spring allows of moving the leaves
laterally sufficient to engage the dowels.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
•
A table having leaves for extending the length thereof, constructed, arranged,
and operating substantially as hereinbefore described with reference to the
drawing.
