EXTENSION-TABLE.

Specification of Letters Patent.

Patented Apr. 27, 1920.

Application fi1ed July 12, 1918. Serial No. 244,553.

To all whom it may concern:

Be it known that I, HARRY CRUMP, a citizen of the Dominion of New Zealand, and residing at 25 Park avenue, Auckland, in

the Provincial Districtof Auckland, in'thev Dominion of New Zealand, have invented certain new and useful Improvements in Extension-Tables, of which the following is a specification.

This invention relates to tables provided with means whereby they maybe extended so as to accommodate a greater number of sitters than normally use the table, and the object of the invention is to provide a table which is readily and instantly extended by merely operating false ends with which the table is provided.

According to this invention, false ends of a table are provided with slides which pass through the ends of the table frame and through guides at or near the center of the table. 7

The false ends are pulled out and pushed in by simple physical forces, or mechanism is employed whereby the drawing out or pushing in of one false end causes the other false end correspondingly to. be pushed in or pulled'out, or mechanism is employed and operated to push in or pull out the false ends simultaneously.

Mechanism employed when the operating of one false end operates the other false end comprises slides fixed to the false ends and provided with racks, and a pinion or pinions gearing with the said racks. When one false end is operated the motion is transmitted in a reverse direction by the pinion or pinions to the other rack or racks and false end.

In one construction, each false end has a central slide to which a rack is fixed, and slides at the sides of the table act as guides for the false ends.

In another construction, the central slide is dispensed with, and slides at the sides of the table are provided with racks and pinions.

Mechanism employed to operate both false ends in opposite directions comprises a pinion or pinions and racks, the said pinion or pinions being driven by turning a handle or key.

In one construction the racks are fixed to a central slide and gear with a pinion fixed to a spindle fitted with a handle or key at one or both sides of the table.

In another construction the central slides are dispensed with, and slides at the sides of the table are provided with racks gearing with pinions fixed to a spindle fitted with a handle or key at one or both sides of the table.

Each extension comprises a leaf fixed to and movable with the false end and other leaves flexibly connected to the said fixed leaf. The table top is supported upon brackets or slide boxes fixed to the sides of the frame, and the said sides are cut away to allow the flexibly connected leaves to pass beneath the table top when the false ends are pushed inward, and to pass from beneath when the said ends are pulled outward.

The invention may be conveniently and advantageously carried into practice as shown in the accompanying drawings, wherein z- Figure 1, is a side elevation with the extensions not drawn out,

Fig. 2, is a side elevation with the extensions drawn out, i

Fig. 3, is a plan with the false ends drawn out and part of the table top and the extensions removed, this view showing both brackets 27 and boxes 27* hereinafter described,

c Fig. 4, is an end elevation of the table, showing boxes 27 but not brackets 27,

Fig. 5, is a cross sectional elevation on line 55 Fig. 1

- Fig. 6, is a sectional elevation, and

Fig. 7, is a side elevation embodying the construction when the racks are operated by a pinion spindle and handle.

The false ends 10' and 11 are fixed to slides 12. which are supported by passing through the ends 13 of the frame of the table,,and through a bar 14 extending transversely between the sides 15 of the said frame. Broad leaves 23 are flexibly connected together by hinges, links or bands 24-, and the first of said leaves 23 is flexibly connected to a leaf 25 fixed to each false end 10 and 11. The sides 15 are cut away at the top and have sloping ends 26. The table top 22 is supported upon brackets 27, which are fixed to the sides 15 and bow outward to extend around the ends of the leaves 23 and then turn inward to support the table top, which is fixed to the said brackets.

A horizontal passageway 28 with inclined ends is thus formed between the sides 15 and'the table top 22, whereinto the broad leaves 23 may pass, moving along it in a straight line without inversion and lying fiat and horizontal therein, parallel to the top of the table. Instead of brackets 27 slide boxes or casings 27 may be employed, which cover the ends of the leaves 23 as well as support the table top 22.

Carriages consisting of bars connected together by a hinge 31, are connected at their other ends to the ends 13 of the frame and to the false ends 10'and 11 by hinges 32. The said carriages 30 open and close automatically on their hinges when the false ends 10 and 11 are drawn out and pushed inward, and form supports for the leaves 23, when the same are drawn out of the passageway 28.

' The false end 10 or the false end 11 and the leaves 23 can be pulled out or pushed in separately by simple physical force.

I The false ends 10 and 11 may be operated by providing central slides 16 and 17 provided with racks 18 gearing 011 diametri+ cally opposite sides with a horizontal pinion 19, the spindle 20 of which is operable by a. key passed through a small hole 21 in the table top 22, or is operable from below the table by a handle, key or wheel.

Again the false ends 10 and 11 may be operated by the mechanism, shown in Figs. 6 and 7 wherein a vertical pinion 35 is fixed to a spindle 36 extending transversely across the frame 15 and operable by a handle 37, a key or a wheel. Racks 38 and 39 gearing on diametrically opposite sides with the pinion 35, are fixed to the slides 12 and 12 respec tively, which are housed in a slide box 40. The slide 12 is reduced in depth at that part of the same whereto the rack 38 is fixed. The rack 39 is fixed to a stirrup shaped bracket 41 secured to the slide 12,

' the bottom of the bracket beingextended laterally to receive the said rack 39. A pinion 35 is provided at each side of the table when the racks are fixed to the slides 12 and 12 as described. may, however, be fixed to the central slides 16 and 17, in which case they are arranged close together and the racks and a single pinion are arranged as shown in Figs. 6 and 7.

The legs 42 are detachably connected, so that theymay be readily removed for the purpose of reducing space occupied by the table during transport. A bolt 43 project- The racks 38 and 39 ing from the end of each leg passes through a stretcher 44: extending transversely across, or longitudinally along, and fixed to the bottom of the frame 15. Or the said legs may be fixed to the stretcher by more than one bolt, or by brackets or otherwise. Also by fixing the legs to a stretcher as described, space is provided above the said legs for the passage of the slides 12 and 12.

Letters Patent of the United States is 1. An extension table having false ends supported fixedly and flexibly connected broad leaves arranged in series and attached to the said ends, said table being also provided in its middle part under its top with.

a horizontal passage and said leaves being arranged in shortening the table toeenter said passageway moving in a straight line therein without inversion and takeposition horizontally under said table top.

2. The herein described extension table,

having false ends to which flexibly connected leaves are connected, devices fixed to the frame of the table and supporting the table top, the said devices being bowed out ward and the sides of the frame being cut away, whereby a passageway is formed beneath the table top for the flexibly connected leaves, substantially as set forth.

3. The herein described extension table, having false ends to which flexibly connected leaves are connected, slides connected to the false ends and provided with racks,

' What I do claim and desire to secure by.

and a horizontal pinion gearing on diametf rically opposite sides with the racks, the spindle of the said pinion being operable by a key passing through a hole in the table top, substantially as set forth.

4:. The herein described extension table, having false ends fixed to slides supported by the frame of thetable, flexibly connected leaves connected to the said false ends, col---
