To mask the anchoring blocks which are suit
ably secured to the side rails and for ornamenta
tion in forming an unbroken or non-gap surface
between the two extension slides when nested,
and for bridging the space therebetween, are the
auxiliary rails 22 secured to the top as at 23.
The opposite ends of these rails 22 as at 22a may
serve asv stops for the rear edges of the exten
sion slides when in nested relation.
Any other suitable method of mounting the
table top upon the frame work and providing open
spaces at the ends of the frame immediately be
neath the top for nesting the slides may be em
ployed without departing from the broader fea
15 tures of this invention.
Extending from one auxiliary side rail 22 to
the other is an elongated member 24, the same be
ing secured to the table top as at 25. Portions 26
of the member 24, in depth, are approximately

Words, the depth of the opening between the
frame and the main top. The auxiliary rails 22
mask the ends of the member 24 at the extensions
26. rl‘he member 24 inwardly of the extensions
25 28 is of greater depth and includes spaced slots 27.
‘These slots 21 accommodate the slide bars.
Herein a pair of slide bars 28 is provided for each
top extension and is suitably secured thereto as at
EU. The slide bars for each extension are offset
relative to the bars for the other extension and‘

tom edge of a notch 42 in an end rail l2, as shown
clearly in the right hand portion of Fig. 2, to
maintain the slide extension I‘! in position as an
extension or continuation of the main top H).
The spring 3'! permits the cam like head 43 of
the member 39 to ride under a locking plate 44,
suitably secured at 45 in countersunk relation
upon the bottom of the table top. The counter
sunk portion communicates with the elongated 10
slot 46 which is provided to permit tilting move
ment of the member 39. A rod 41 is suitably se
cured to the member 39 as at 48 and is slidably
mounted in a groove 49 formed in the face of the
slide bar bearing or the slide. The rod 41 carries
at its free and outer end, a pull ring or similar
device 50.
The underface of each table top extension is
provided with a ?nger grip or groove 5|.

The slide is engaged by gripping the same at
5! and is pulled outwardly to remove the slide
from its nested position, shown in Figs. 1 and 2
at the left, and as it is moved outwardly, the block

that the movement is more or less. in an inclined

considerably deeper than the depth of the bars.
plane directed upwardly into the plane of the
main table top. Near the immediate end of the
extension movement, the depending portion 4| of
the hardware, engages the bottom surface of the 30
slot 42 in the end rail l2. When thus engaged,
the top extension is maintained in table top
extension-forming position. When it is desired
to nest the extension, the two pull rings 58 are
Each bar near its free end carries an inclined
member or block 38 which engages the bottom of
supporting position, permitting the extension to
the recess 27 and causes the slide in its extending
movement to be automatically elevated until the
full extending movement is obtained. Near the
40 end of the extending movement certain hardware,
the speci?c subject matter of the invention, auto
matically becomes operable to elevate the top
extension into the same plane as the table top
at the end of the extending movement and to
45 thereafter support the same in such plane until
subsequently manually and positively released.
Each bar intermediate its ends includes an in
clined block 3! which has one edge 32 adapted to
serve as a stop by engaging the inside of the end
50 rail l2 when the slide is extended.
In alignment with each slide bar and near the
free end thereof when the extension top is nested
and secured to the table top, is an inclined block
33 which serves to force downwardly the rear or
55 free end of the slide bar and also serves more or
less as a stop to prevent upward tilting of the ex
tension top in the initial extending movement
thereof. In other words, the end of the bar must
?rst clear the inclined member 33 before rela
tively great tilting or elevating movement in the
extending movement of the extension top is
possible. This prevents marring of the top ex
tension.
In Figs. 1 and 2 of the drawings, one, and the
65 preferred individual form, of the automatically
operable and manually releasible hardware for
elevating without retraction of the extension top,
illustrated. In said ?gures, the slide bar is
recessed as at 313 and suitably secured therein, is
a base plate 35. Said base plate has a tongue
struck therefrom to lie within the con?nes of
the recess 34.
Said tongue serves as an anchor
age for spring 31 secured .as at 38 to a depending
arm 35? of a member which is pivoted as at 123
75 on said plate. The member 39 has a depending
engaged which tilt the members 39 from their 35
drop downwardly and thereafter inward move
ment of the extension will nest the same beneath
the table top.
In the form of the invention shown in Figs. 1 40
and 2, at the end of the extending movement,
the upper portion 43 of member 39 having the
notch 52 therein, through the influence of spring
37, serves to receive the edge of plate 154 to fur
ther lock the extended leaf in the elevated
position.
The plate 35 has struck from it a stop 53 which
limits tilting movement of member 39 under the
in?uence of spring 31.
In Fig. 4 a modi?ed form of the invention is 50
illustrated and in said ?gure, numerals of the
one hundred seriesv are utilized.
In this form
of the invention, the additional sustaining means,
such as the plate 43, cam portion 633 and notch
52 of the member 39, are omitted.
In Fig. 3 a still further modi?ed form of the
invention is illustrated and the same may be uti
lized with either form of the invention shown
in Figs. 1 and 2 or Fig. 4. In this form of the
invention a single pull member is provided to 60
simultaneously actuate both of the automatic
mechanisms embodying the hardware, the sub
ject matter of the speci?c invention disclosed
herein.
