To all lwho/2.12 ifmuy-cmicera: ,c

Be it Iknown that l, JULns ARMAND BLIN, t-'citizen of the French Republic, residing at Paris, France, lia-ve `invented new and useful Improvements in Drawer-Guide Construction, More Especially for Metal Fur- -nitures, of which the following fis ay specification.

rlhis invention vrelates to drawerV guide construction 'and `its object lis to provide means for safely guiding the drawer in its iarticle and for -holding it securely in its `position of maximum yopening without -any overh'anging and no matter what 1thel weight of the contents maybe.

This guideconstruction is especially well adapted forin'etal furnitures as `described in my vco-pending application fory Letters Patent Serial No. 515109, filed on November 14, 1921, of which Athe present case is a division.

A constructional form of the'invention is shown in the accompanying drawings wherein:

Fig. 1 is a side view of a drawer;

Fig. 2 is a sectional view of the same;

Figz is va planview'of the drawer and of its arrangement in the article to be used therewith Fig. 4 shows separately in longitudinal elevation, one of the fixed runners of the arrangement g Fig. is a face view thereof; l

Fig. 6 likewise shows separately and in longitudinal elevation one of the movable runners forming a guide for the drawer;

Fig. 7 shows in side view, the complete drawer and its guiding means;

Fig. 8 shows in cross section to a larger scale, the whole of one of the guiding arrangements for the drawer, and

Fig. 9 likewise shows to a larger scale one of the pins which limit the movement of the drawer.

rlhe body of the article of furniture which is to receive the drawers consists of two side panels b each comprising an aluminum plate suitably bent and shaped to form half the bottom b1, one of the lateral sides and a rigid upright head b2, slightly set back, against which the front plate of the drawer closes when it is fully pushed home.

The members for supporting the drawers consist ofmetal strips p in the form of thereof 'of the strip p, with two rollers g and q1 carried by spindles fr inthe side of rsaid strip and supported by bridge pieces r1 (Fig. 8).

The drawers are provided on each 'lateral side with rollers s and $1 mounted freely on spindles t, f1 and between which can engage a movable slide u comprising, simil'arly to the 'fixed slides, metal bands suitably bent over to form adouble guideway. These 'are kmovable slides and VAhave at each end removable pins o, o1 (Figs. 6, 9) held in position by rubber sleeves ai, aal and 9). These latteryconsist of rubber sleeves whose internaldiameter is equal -to or preferably, slightly lessin diameter than lthe pins t which they surround. It results that these sleeves, by reason of their resiliency, expand when theI pins pass into them and compress strongly onto such pins.

ln order to secure these to the movablev slides u, the sleeve 012 is rstengaged within the slide opposite circular holes formed in the edges of the guideways for thel passage of the pin, then this latter is introduced in the sleeve m2 until each of its extremities protrude by an equal amount above and below the guideways formed by the slide u. The sleeves a: and :r1 are then slipped on the protruding extremities of the pin.

This method of mounting the pins and their sleeves so as to form abutmentsavoids all fixing means, while yet enabling them to be put in place or removed quickly and easily.

r1`he drawer so constructed is placed in the article of furniture in the following manner.

Each of the movable slides u is engaged on the two rollers Q, Q1 carried by the fixed slides p1 so that these rollers can turn on their spindles inside the movable slides.

1V hen these latter are fully engaged, the rear pins '111, which penetrate into the sleeves .r2 which have irst been introduced into the movable slides, are fitted and then the sleeves a: and :c1 are placed on each of the eX- treniities of the pins which are thus held on the slides and at the same time ensure the connection between the movable slides and the fixed slides.

lt is then only necessary to push the drawer into the article of furniture by engaging it so that .its rollers s and S1 bear on each upper and lower edge of the movable slides a. When the drawer is sufficiently entered on the movable slides, the front pins e with their rubber sleeves m, w1 and m2 are put into position in the same manner as described for the rear pins.

The drawer is thus maintained inside the furniture by the rollers g and Q1 engaged in the movable slides u and by its rollers s, s1 which run on these slides.

lf the drawer is opened, the movable slides u move or. the rollers y, Q1 carried by the iixed slides until the rear pins @l abut against the rollers g1 which thus limit the .movement of the movable slides.

By continuing to pull out the drawer, the latter slides, by reason of its rollers s, s1, on the slideway formed by the movable slides a until the front rollers a and 81 abut against the sleeves and ail of the pins v in the direction of the arrow, F ig. 7. The pins and the rollers are disposed so that the drawer can be pulled fully outwards till the front rollers abut against the pins e. In this position of full opening, the drawer is eiliciently held or supported, without hanging down and immaterial of the weight of the contents, by the two movable slides with which its rollers are always in engagement, these two movable slides remaining engaged and held in the interior of the piece of furniture over the greater portion of their length, by the rollers g and g1 carried by the fixed slides j?.

`On the other hand, the rubber sleeves .fu and Q21 against which abut the pins v and 1v1 form shock absorbers and prevent noise.

I claim:

l. An article of furniture, a drawer guided therein, metal guide-strips having rolled edges fast to the internal side walls of the furniture and parallel with the sides of the drawer, fixed spindles and freely turning rollers mounted thereon on the external face of the lixed strips, a movable slide with rolled edges riding on and embracing each pair of rollers on each fixed guide strip, and a superposed roller and a pair of sublocated spaced rollers positioned on opposite edges of the movable slide and mounted along the sides of the drawer to run on the edges of each movable slide, as described.

2. An article of furniture, a drawer guid ed therein, metal guide strips having rolled edges fast to the internal side walls of the furniture and parallel with the sides of the drawer, fixed spindles and freely turning rollers mounted on the spindles on the eX- ternal face of the fixed strips, a movable slide with rolled edges riding on and em* bracing each pair of rollers on each fixed guide strip, rollers mounted along the sides of the drawer positioned to run on opposite edges of each movable slide, removable pins projecting through the edges at the ends of each movable slide, and rubber sleeves tightened on the middle portion and on the external portions of said pins, as and for the purpose described.
