DRAWER-LIFTTNG SUPPORT.

My invention relates to articles requiring to be withdrawn, or opened, and returned to place, or closed, by sliding movement in suoli manner as to prevent Jamming, or working stiiiiy in the housings in which they slide, said articles being of the type in which an extensible arm of the kind known as lazy tongs is employed at the side, or both sides of the article, the present invention being more especially intended for application to drawers which are sliddeii into, and from, a chest in which they are housed and, in describing my invention, I will presume that it is so applied, from which its application to analogous articles (such for instance as the specimen cases of cabinets) will also be understood.

According to my invention there is connected to the forward part of the drawer, (and usually, for ease of movement at each side of the drawer) one end of the extensible arm, the other end of which is engaged within the housing in the chest with a guide, which will impart an upward tilt to the forward end of the said arm, so as to lift, or tend to lift the drawer as it is withdrawn and relieve it from the friction, or some of the friction, incidental to its slidingmovement from, and into, the chest.

I will describe, with reference to the accompanying drawing, a construction in accordance with my invention.

Figures l and 2 are both side elevations partly in section one shewing the drawer closed and the other shewing the drawer opened.

At each side of the drawer A is an extensible arm consisting of a system of links b connected together, at their mid-parts and at each end by pins in the mannerl of the devices known as lazy-tongs, the foremost c2 of the pins C being mounted in a plate Z secured to the forward part of each side of the drawer, whilst the rearmost and the third of the pins (those marked respectively 03 and 04) are capable of-sliding in, or on,

guides secured inside the chest B and ofsuch inclination as'to somewhat tilt the forward end of the said lazy-tongs arm when the drawer is being opened. The said guides are preferably slots, f, f2 in line -with each 730,648. and in Great Britain July '7, 1924.

other, in a plate g, secured to the inside o-f the chest-housing for the drawer, in line with the centre-pin attachment (c2) to the forward part of the drawer A. The centrepin 05, between the rearinost pin c3 and the third pin c4 of the lazy-tongs arm, is mounted in the aforesaid plate g inside the chest so that this pin c5 constitutes a longitudinally fixed centre between the two slots j" f2 upon which centre the lazy-tongs arm turns sufficiently as the aforesaid rearmost and third centre-pins c3 and c4 move along their respective slots f2 and f to give the aforesaid lifting, or tilting, movement to Jthe drawer A. The sides of the drawer are suliiciently recessed, or set inwards, to accommodate the lazy-tongs arms and their connections and the upper edges of the said sides are sufliciently reduced in height (as shewn at a) to allow of the said lifting, orl

tilting, movement. It is understood that there are also similar devices at the other side of the drawer A. When the drawer A is shut, or slid, into the chest B, the lazytongs arms will collapse, as shewn in Figure 2, and the drawer A takes up the closed position upon its supports in the chest B as the rearniost and third centre-pins c3 and o* move toward the pin o5 in their respective slots f2, in the plate g secured to the inside of the chest B.

In the following claims it is to be understood that drawer includes also analogous slidable objects, lazy-tongs arm includes also any suitable extensible and retractable device of an analogous character and chest7 covers also any equivalent housingfinto, and from, which the drawer, or other object, slides.

IVhat I claim is l. For use with drawers and analogous slidable articles housed in a chest, having a lazy tongs arm providing a support for the slidable article, pins connecting the elements of the lazy tongs arm, in combination with a guide having two slots mounted in a side wall of the chest, an intermediate one of said pins being fixed in said guide between the two slots, and another of sai-'d pins on each side of said intermediate pin sliding in a slot.

2. For use with dra yvers and analogous from one end of the lazy tongs arm being slidable articles housed in a. chest7 having a liXed in said guide between the two slots, lazy tongs arm poviding a support for the and the first and third of said pins sliding 10 sliclahle article, pins connecting the elements in the two slots, substantially as'desoribed.

5 of the lazy tongs zum, in combination with u En testin'iony whereof I have signed my guide having two slots mounted in a, side mime to this specification. wall of jthe chest, the second of said pins ROBERT HENRY COLLEN.
