CARRIAGE FOR DRAWER-S AND THEV LIKE. l

Application filed February 26, 1925,`Seria1 No. 11,774, and in Canada September 29, 1924.

The invention relates to improvements in carriages for drawers and the like as described in the present specification and shown in the accompanying drawings which form part ofthe same.

The invention has for its object to provide-a carriage for drawers or trays which will permit of their being pulled out almost clear of their containingcompartments in order thatv articles may be placed therein or removed therefrom with the utmost of ease. A further object is to construct and arrange the carriage in such a manner Vthat the drawer rests vupon extensible slides without making any actual physical Vconnection with the carriage that would hinder the drawer fromy being readily removed from its compartment. The drawer furthermore automatically locks in its extended position so ask to prevent it from sagging Or tipping. A still further object resides in the provision of means for causing the slides of the carriage to automatically travel with the drawer as the same is drawn open.

The invention consistssubstantially of a carriage having one or more slides upon which the drawer rests and extendingY alongside of these slides areguides for the purpose of preventing lateral shifting of the drawer and at the front. of the said guides interlocking means are provided for .the purpose of preventing the drawer from sagging when fully withdrawn, while at the rear of the guides lresilient catches are provided for the purpose of engaging the slidying members thereof in order to cause them to move outwardly with the drawer.

Referring to the drawings, Figure 1 is a typical illustration of the practical application ofthe invention as applied to a drawer of a bildet, which buffet is shown broken away at one end.

Figure 2 is a rear perspective view of a.

drawer fully extended upon its slides.

Figure 3 is a further perspective view depicting the drawer removed from its slides,

Aboth the drawer and the carriage being illustrated in aninverted position.

Figuref@ is a perspective view of the stationary member of one of the slides, the lrear end of which is shown broken away.

Figure 5 is a fragmentary view of a rear corner of the drawer and one of the guides illustrating the catch for causing the automatic travel of the slide with the drawer.

. Figure 6 is afurther perspective View of one of the stationary members of the slides exhibiting the stopblock at its end.

Like numerals of reference indicate corresponding parts in each figure throughout the drawings.

Inv the drawings, the buffet 1 shown in Figure 1 is provided with a substantial compartment 2 containing the drawer 3. This compartmenty is vclosed by a drop door 4 Va dovetailed groove l1 extending throughout its entire length constituting a mortice. At the forward end of each of` these stationary members is a tenon 12 in the form of a double. dovetail,one of which dovetails is fixedly secured in the groove 11.-

13 indicates the sliding members of each of the slides which are provided with similar grooves in their under faces as at 14.

Fitted in each of these grooves are further tenons 14a similar to those aforesaid, the said tenons being securely fastened in their respective grooves in any manner found convenient. Thesel sliding members 13 are assembled with the stationary members 10 by merely sliding the tenons 12 and 14a in their corresponding dovetailed channels, in

this manner being free to move longitudinally therein. By making the tenons of each of the slides of a certain length the Vsliding members can-be slid forwardly until they extend about half-way over the end of their respective stationary members, thus .providing a support for the drawer in its extended position and at the same time by means of this interlocking engagement .the sliding members cannot extend beyond the points of abutment of their tenons.

lnorder to prevent the'sliding members of the slides yfrom becoming dismantled,

.stop-blocks are provided at the rear ends of the stationary members, said stopblocks consisting of pivoted bars 15 rotatable about the axis 16 so that their ends may be swung in such a position .as to obstruct the mortice passageway 11 of their respective stationary members, thus forming an obstruction for the tenons lila.

rl`he drawer 3 is assembled on the slides 13 by merely resting it thereupon and, in order prevent the saine from shifting' laterally, longitudinally ext-ending strips 17 are provided on the underside thereof; one of such strips being positioned along the inner side of each of the slides. Each of these strips is recessed as at 18 at its rear end and fitted in suoli recesses are resilient clips 19 having an enlarged head 20, best discernible in lligure 5. Positioned in advance of these clips when the drawer is in its closed position are screws 21 carried by each of the sliding members 18 of the slides. These screws are so situated that their heads lie in the path of the clips 19. By this construction it will be seen that upon pulling the drawer outwardly these clips will engage their respective screws and cause the slides to move with the drawer until they reach their outermost position, when the clips will automatically release and the drawer continue upon its journey until it reaches its fully extended position. Upon closing the drawer, the reverse action ensues.

22 indicates a rabbet or channel extending longitudinally of the upper face of each of the sliding members 13, such rabbets eX- tending from the rear end thereof to a point intermediate of their lengths. Fitting in each of these rabbets is a bloclr` 23 which is fastened to the under surface of the drawer bottom at its rear end so as to provide a forward limiting stop for the drawer. At the forward end of each of the stationary members of the guides is an inverted L-shaped member 24 which engages a recessed block 25 that is securely attacl ed to the drawer bottom at the rear end. These members 211 and 25 interlock in the fully extended position of the drawer in order to prevent it from sagging or tipping out of its containing compartment.

In the operation of the invention, upon drawing out the drawer the clips 19 engage the heads of the screws 21 by means of their enlarged heads 20, thus inducing the sliding` members to travel with the draw r until they reach their outermost position, where they encounter the tenons of the stationary members 10, this obstruction preventing the members from further outward movement. As the drawer is further extended the clips on account of their resiliency automatically release themselves, and upon the bloclrs 23 encountering the terminations of the grooves 22 the drawer is automatically brought to a stop. The 5..-shaped blocks 2&1 engaging the recessed members 25 interloclr the drawer with its slides in its extended position and prevent it from sagging or tilting. 1n closing the drawer, the spring clips engage the screws 21 and carry the sliding members 13 baclr to their normal position again.y

lt will be readily seen that in order to remove the drawer from the carriage, it is merely necessary to withdraw it and raise the rear end slightly to avoid the L-shaped members 24, thus entirely removing the drawer from its containing compartment.

Wherein the inventionhas been shown and described in its employment of a pair of slides 9, it will be readily manifest that one or a plurality of the same may be Yemployed in this capacity and it is not intended to restrict the invention to any specific num.- ber of such slides, nor to their being positioned in any particular location as it is clearly apparent that they would function equally well were they placed at the sides of the drawers.

Whilst l have illustrated and described what l new consider to be the preferred embodiment of my invention, it is understood that the device may be modified in various ways Vvboth as to form and construction of the several parts and also as to the arrangement without departing from the spirit of my invention. l therefore do not` wish to restrict myself closely to the precise disclosure made, but wish to avail myself of all` such modilications as may fall within the scope of the appended claims.

W'hat l claim is I 1. ln adevice of the class described, th combination with a longitudinally extensible slide upon which a drawer both rests and nieves, of an interlocking member located at the forward end of said slide, and a complimentary interlocking member carried by the rear of the drawer, said interlocking members being arranged to engage each other as the drawer is fully extended upon the slide to preclude its sagging or tipping.

2. ln a device of the class described, longitudinally extensible slides upon which a drawer both rests and moves, a stationary member located at-the forward end of each slide, members carried by the rearward end of the drawer, one in the proximity. of each slide for engagement with its stationary member, the aforesaid members being constructed and arranged to automatically interloclr as the drawer is fully extended upon its slides in order to preclude its sagging or tipping.

3. ln a device of the class described, longitudinally extensible slides upon which a drawerboth rests and moves, an inverted L- shaped member aflixed to the forward end of each slide, recessed bloclrs carried by the rearward end of the drawer, one positioned in the proximity of each slide and arranged to automatically engage its L-shaped member as the drawer is fully extended upon said slides in order to preclude its .sagging or tilting.
