COMPLETE SPECIFICATION.
Improvements in Extension Tables.
We, JOHN PINTHER (Cabinet Maker), MORRIS SAUBER (Clerk), and JACOB
GREENBERG (Treasurer) all of 96 Church Street, New York, in the County of
New York and State of New York, United States of America, 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 extension tables, and the object thereof is to provide
an improved device of this class which is simple in construction and operation,
and which may be drawn out or extended when desired, and also compactly folded
together when a long table is not required.
The invention is fully disclosed in the following specification of which the
accompanying drawing forms a part, in which;-
Fig. 1, is a side view of our improved table with a part of the side thereof
broken away;
Fig. 2, a transverse vertical section on the line 2, 2, of Fig. 1;
Fig. 3, a longitudinal section showing the table extended;
Fig. 4, a bottom plan view of an endless apron which we employ; and,
Fig. 5, a bottom plan view of a slide which forms a part of our improved table,
and which will be hereinafter described.
In the drawing forming part of this specification the separate parts of our
improvement are designated by the same numerals of reference in each of the
views, and in the practice of our invention we provide a table which when not
extended, is preferably practically square, as shown in Fig. 1, but when extended
is oblong in form, as shown in Fig. 3.
Referring to Figs. 1, 2, and 3, of the drawing, we have shown at 5, the opposite
sides of the main part of our improved table, and at 6, the ends thereof, and this
part of the table is supported by two legs 7, at the outer end of the table, and a
central leg 8, at the inner end thereof, but there may also be two of the inner
end legs if desired, and the extensible part of the table is supported by two
legs 9, and the upper part of the legs 9, of the extensible part of the table are
also provided with an end board 10, which is adapted to close up against the
corresponding end 6, of the main part of the table.
The extensible part of the table is provided with a stationary table board 11,
and secured to the bottom thereof longitudinally of the table, and near each side
are bars 12, and supplemental bars 13, are connected therewith, by means of a
tongue and groove joint, and are adapted to slide thereon, and said supplemental
bars are also connected with the sides 5, of the main part of the table by a tongue
and groove joint as shown at 14, and the supplemental bars 13 are free to slide
on the bars 12, and in the sides 5, of the main table.
The bar 12, is provided on each side with a cross plate 15, as shown in Fig. 5,
which is secured thereto and overlaps the supplemental bar 13, and the supple-
mental bar 13, is provided with a cross plate 16, which is secured thereto, and
which overlaps the bar 12, and the object of these plates, which are the same on
both sides of the table, are to guide and brace the brace bars 12, and 13.

page_text: Formed in the inner surface of each of the sides 5, of the stationary part of
the table, and at the upper part thereof near the outer end is a curved groove 17,
and these grooves are continued downwardly at the outer end of the said sides 5,
and then backwardly and horizontally thereof, and then upwardly and then
forwardly again as shown in Figs. 1, and 3, and coiled around the inner wall of
this groove and extending throughout its full length is a strip of metal 18, and
these strips of metal after leaving the groove 17, rest on the top of the sides 5,
of the table, as shown in dotted lines in Fig. 3, and in full line in Fig. 2, and
terminate at the inner end of the main table as shown in dotted lines at 18".
The slot which forms a part of the tongue and groove connection between the
supplemental bars 13, and the sides 5, of the main part of the table, is continued
along said sides 5, as shown at 19, in Fig. 3, and we also provide an apron which
consists of transverse strips 20, the vertical thickness of which is equal to that
of the board 11, of the extensible part of the table, and these strips are connected
on their under side by flexible bands or straps 21, as clearly shown in the
drawing and the inner ends of these flexible bands or straps are secured to the
table board 11, as shown at 22, and the ends of the strips 20, are formed as shown
in Figs. 2, and 4, being provided with extensions 22, which move in the grooves 17,
and these extensions are formed by cutting. out the under sides thereof, and
formed in said strips at the ends of said extensions, are transverse grooves 23,
which form a continuous groove throughout the length of the apron, as shown
in Figs. 1, 2, 3, and 4.
The main part of the table is also provided with a supplemental table board 24,
which is hinged to the outer end thereof, as shown at 25, and which is provided
with a transverse end piece 26, on the lower side thereof, with which the hinges 25,
are connected, and said end of the table, is also provided with a pivoted arm or
lever 27, which is designed to hold the supplemental table board 24, in the
position shown in Figs. 1, and 2, and by turning said arm or lever 27, the
supplemental table board 24, may be turned down so as to permit of the operation
of the table as hereinafter described.
The supplemental bars 13, as hereinbefore described, are free to slide on the
bars 12, and also in the sides 5, of the main table, said sides 5, being provided
with the grooves, 19, for this purpose and the inner end of the table is provided
with openings 28, through which the bars 13, pass, but the length of the apron
is such that these bars, cannot be entirely detached from the extensible part of the
table, or from the main table, and the said bars 13, are provided at their inner
ends with downwardly directed pins or projections 29, which operate in con-
nection with catch plates 30, secured to the inner end 6, of the table, in order
to prevent the separation of these parts.
The operation will be readily understood from the foregoing description when
taken in connection with the accompanying drawing, and the following statement
thereof.
By turning down the lever 27, and depressing the outer edge of the supple-
mental table board 24, the extensible part of the table may be shoved in, and
in this operation the apron will move downwardly and around the grooves 17.'
In this operation the extensible portion of the table may be shoved inwardly,
or to any desired extent, and at any point, the supplemental table board 24, may
be turned down into the position shown in Fig. 3, and the lever 27, operated to
hold it in this position, and it will thus be seen that the table may be extended
to any desired point, within the limits of the length of the apron, or said apron
may be entirely drawn out if, desired, until the supplemental table board will
strike against the end strip 20, of the apron.
When the table is extended or partially extended, the end extensions 22, of
the straps 20, of that portion of the apron which is drawn out, rest on the sides 5,
of the main part of the table, and on the sliding bars 13, as will be readily
understood, and as clearly, shown in Figs. 2 and 3, and the sides of the table
board 11, of the extensibe part of the table are also provided with grooves 31,

page_text: shown in dotted lines in Fig. 3, to correspond with the grooves 23, in the strips 20,
of the apron, and these grooves 31, in the sides of the table board 11, are adapted
to receive the ends of the strips 18, when the table is entirely collapsed ör
folded together.
Our improvement is simple in construction and operation, and perfectly adapted
to accomplish the result for which it is intended and it will be apparent that
changes in and modifications of the construction described, may be made without
departing from the spirit of our invention, or sacrificing its advantages.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
