COMPLETE SPECIFICATION
Improvements in Expanding or Extending Tables
I HERMANN RUIHKF, Cabinet Maker, of Breitestrasse 3 Stettin, in the
Empire of Germany, 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
-
nioved
This invention has the advantage, that in expanding or drawing out the
table leaves the upper or fixed leat or table top neel not be raised of
so that any shaking of the same and consequently of objects which may be placed
on it, is presented it also averts the danger of pinching the fingers during the
operation of drawing in or expanding said table Moreover the ari ingement is
such that it may easily be applied to tables of any kind and its construction does not
admit of drawing in the extended leaves until after the diseng igement of a locking
arrangement which insures the position of the leaves when extended
This table is represented in the annexed di wings in which Fig 2 shows a plan
view of the same, as seen from underneath, Fig 1 is a longitudinal section on
line XX, Figs 3 to representing details ou a luger scale
,
The upper pu mitic end. A of the lege connected in the usual manner by
the frame bai. B B C C the top plate D is fastened only to the longitudinal
bars B B in such manner that it is screwed on to the central cross piece E which
connects and is fixed to the bats B B Thu when the leaves FF' are pulled
out the top plate D is supported only by said cross piece and towards its ends
it is without support thus lying it an interval a from the upper edges of the sud
bars B B Each leaf F has undeine ith it the bearers G G for which the frame
bir is provided with corresponding grooves b b Io prevent a complete
pulling out of the let that is to say to prevent its entire removal from the main
part of the rable the bener Cr are provided at their car deeper ends with pins g
which but against the rear side of the cross bar H, which latter is supported by
means of the piece Kattached to the ci oss piece E
In expanding the table the exterior edges of bais KK serve as guides for the
sliding bearers G G So much is taken off the ends of H as the depth of the
ends of bearers (require
Subject to the hereinafter mentioned locking arrangement the leaf F is pushed
back by slightly pressing it downward thus iemoving it from the edge d of the
top plate D so that the bearers G rest in the notches bb and on the ends of bar H
respectively and turning about these points assume an oblique position If leaf F
is then pushed inwards the sloped inner ends of bearers G soon reach the edges
of the cross picce E, which edges are at the respective ends, also slanted, and
sliding downward along these slanted surfaces pass beneath the surface of cross
piece E so that the thickness of the leaf I is admitted into the space a
The leaf F is on the drawing represented in its original or closed position,
and the parts G' K' H'g' cor espond in iction with the parts G K H 7 of the
leaf F
It is evident that the leaves F F when drawn out either in consequence of
their own weight or at least of that of objects placed on them, would slide off the
edges d were it not for the above mentioned locking arrangement which is intended
to secure them in place The latter consists of a bolt L which for that purpose
lies in the projecting flange M of the bars Fig 3 shows a plan view of these

page_text: parts (the top plate D being supposed to be removed) Fig 4 is a section on
line y y as seen from the right, Fig 5 the same as seen from the left Fig 6 is a
interior view The bolt L has a lateral projection N provided with a pin O
passing through the frame bar B at the other end it has a nose P to which a
pin Qis fastened, the other end of which rests in the block R glued on to bar B
to strengthen the latter When the button is pressed the iod Q slides in its
guiding block thus compressing the spiral spring which acts upon it whereas on
diminishing the pressure on button O the position is that shown in Fig 3
Opposite the notches of the bar C, the bolt L has attachments S, the noses
at the lower ends of which engage in corresponding grooves m of the bearers G G
when the leaves F F' have been pulled out The bearers G G thus receive a
support from the noses S, and the pushing back of the leaves is only rendered
possible when the bolts L have been laterally displaced thereby removing the
projections S from under the bearers G G A similar locking device consisting
of parts O N¹ M' L' S₁ etc is arranged for the leaf 1
The locking arrangement may be provided for in different ways, as for instance,
by a bolt with a button, to be turned and thus engaging in re-pective openings of
the bearers G, and could be actuated automatically to engage in these holes
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim 15
-
1 Expand ng table the fixed plate of which is fastened on to a central cross piece E
connecting the two side frame bars B B whereas the expanding leaves F F' are
supported by bearer G G the extensions of which project when the leaves are
pulled out, downward beyond the fixed plate D to be raised on supports S, which
are fastened on to a laterally displacable bar or bolt L and engage in corre-
sponding grooves of the bearers G, so that the leaves F F¹ can only be pushed
back after this bar L has been displaced
2 An expanding table as de cribed with a locking arrangement for the bearers G
of the expanding leaves consisting of a laterally di placable bar L attached
underneath to the inner side of the end frame bai C, sud bar L, having supports S
for the bearers G, and hept underneath the latter by a spring acting on bar L and
in consequence of the action of that suring engage when the leaf For F' is drawn
out with its projections in grooves of bearers (r, so that the le if can only be
pushed back after the bar L has been brought into its former position
