To all whom t may concern.'

Be it known that I. ALBERT VOIGT, a citizen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented new and useful Improvements in Drawer-Carriers, of which the following isa. specification.

This invention relates to carriers or supports for drawers and the like, such as drawers for wall or show cases and the like, and it is the primary object of the invention to improve the construction of carriers of this type to sim lify the construction and increase the e ciency thereof by reducing to a minimum the fric-tional resistance as a drawer is moved outward from and into its casing.

It is a further object of the. invention to provide a carrier of this type in which the drawer is carried or supported upon rollers wherebythe, drawer is rigidly supported in all positions onthe carrier and the drawer with the load carried thereby is carried upon the rollers substantially centrally thereof with the load at all times equalized upon the rollers.

A further object of' the invention is to provide a drawer carrier or support of this type in which the drawer is releasably connected to the carrier whereby it may be readily and quickly removed without the necessity of removing any parts such as screws or the like.

In carrying out the invention I provide a guide to loe fixed in the casing for a drawer, which guide is in the form of a channel bar, the flanges of which bar constitute opposite runways, and provide an eXtensible slide consisting. of releasable sections, one

section being in the form of a channel bar, the flanges of which also constitute opposite runways, to engage in the guide and supported by rollers upon one of the runways in the guide to have a limited to and fro movement and a roller carried by said slide section being adapted to engage with the runway of the guide opposite to that upon which the supporting rollers run. The other slide se'ction has a part to interlock with and slidably engage in the opening in the first slide section to havealimited to and fro movement with relation to said first slide section, and having an angle portion to engage with and support said slide section upon rollers adapted to ruii upon one of the fianges of its companion slide and having a roller to run upon the opposite flange of said guide, the latter slide section having a part to removably connect a drawerthereto and support the drawer thereby to have movement with said section. Means are provided to releasably connect the slide sections, whereby as said drawer is moved inward substantially midway into the casing -the slide sections will be automatically locked together so that the slide sections will be moved concomitantly into the casing to the full extent with the drawer supported and moving on the rollers in the guide through the extensible slide, and during the outward movement of the dra-wer it will be supported upon said rollers tosubstantially midway of this outward movement when the slide sections will be automatically released and during the further outward movement of the drawer it will be supported upon the rollers in the slide section of channel form through the slide section to which the drawer is connected.

In the drawings accompanying and formv ing a part of this specification Figure 1 is a cross sectional view illustrating an embodiment of my invention, the section of the drawer carried on the slide being taken oir the line D--D of Fig. 2 `and the carrier on the slideV being taken on the line C-C of Fig. 2.

Fig. 2 is a longitudinal sectionalz view taken on the line E -Eof Fig. 1 and looking in the direction of the arrow, and showing the position of the parts when they drawer is in its innermost position.

Similar characters of reference designate like parts throughout the different views of the drawing.

While a drawer carrier constructed in accorda-nce with the embodiment of the invention shown in the drawings in practice is used and applied to opposite sides of the drawer, these carriers are in duplicate'and identical and a detailed description of the construction and operation of only one of said carriers will suiiice for a clear understanding 'of the invention.

The embodiment of the drawer carrier as illustrated in the drawings has been designed to be particularly applicable to drawers for wall cases, and the invention has been illustrated and will be described in connection with such a structure, the casing being shown in a general way by 10 and ladapted to receive one or more drawers having sides 11, 11, a bottom 12 and ends 13, 13, the width of the drawer in the rear of the front end or wall beiiig less than the width of the4 chamber in which it slides to provide a space for the'drawer carrier at opposite sides ofthe drawer.

Thedrawer carrier consists of a channel bar guide 14 with the rear end 14"closed and securedvina vertical position to the side of the 'casing' with the opening in said bar at the side as shown. The upper flange is of slightly less width'than the lower flange, and the flanges have offset flanges 15, 16 whereby the channel bar fianges 14 constitute opposite runways for rollers to be hereinafter described.

The drawer is carried and supported by an extensible slide comprising a pair of sections 17, 18. The section 18 is bent up from a sheet to form substantially a channel bar with the rear end 18 closed and with one of the flanges, as 19, of less width than the opposite ange 20 and a depending portion 23 constituting a continuation or extension of the connection portion of the flanges 19 and 20. Each of the ianges has an offset flan- ge 21, 22 to-adapt the flanges of the channel bar as opposite runways for rollers. This slide section 18 engages in the gulde 14 and is so proportioned that the offset flange 21 will engage in the opening and be in line with the offset flange 16 of the guide, as clearly shown in Fig. 1. The slide section 18 has to and fro movement in the guide for which purpose it is supported upon rollers 24 running upon the lower fiange or runway of the guide, said rollers being pivotally supported and spaced apart or separated by a carrier 25. This carrier is of channel shape in cross section with the open side at the bottom and is of such size and the rollers pivotally supported thereby that it will clear the runway for the rollers and a peripheral portionV of the rollers will pass through openings therein to be engaged by the slide section 18 to support the v latter. Rotatably supported adjacent the rear end of the slide section is a roller 26, a portion of said roller extending through an opening in the upper flange 19 of said slide section to engage with the upper runway of the guide. During the to and fro movement of said slide section it will ride upon the rollers 24 and said rollers with their Carrier will ride along the lower runway of the guide, the inward movement of the slide section being limited by the engagement thereof with the end wall of the guide, a suitable cushion 27 taking up any shock as the slide section abuts against said end, and the outward movement is limited by the forward end of the roller carrier 25 engaging with a stop 28 removably secured in the lower. runway of the guide and a stop 29 depending from the slide section engaging with the rear end of the roller carrier 25, suitable cushions 30, 30 being carried at the ends of said roller carrier to take up any shock incidental to the abutting of the carrier against the stop 28 and the stop 29 abutting against the roller carrier. These cushions may be in the form of a felt pad carried by staples 31 engaging in slots in the 95 end of the roller carrier formed by bending the ends of the flanges of the roller carrier inward. The stop 28 carries a roller 32 rotatable on a vertical axis, a portion of the periphery of the roller passing through a slot in the offset flange 16 of the guide to engage with the side of the drawer to facilitate the sliding of the drawer into the casing.

The slide section 17 has a laterally extending flange portion substantially of channel shape in cross section, as shown at 33, in which the lower edge of the side of the drawer engages. The ends of the channel flange are closed, as at 34, with the closed end at the rear abutting against the rear end of the side of `the drawer and the wall to close the front end engaging in a transverse slot in the bottom edge of the drawer side. At the upper end the slide section 17 has a lateral flange portion substantially of channel shape in cross section, as shown at '35. It will be understood that this flange extends from the slide section opposite to the vflange 33. The flange 35 engages inthe open side of the slide section 19 and over a roller carrier 36, similar to the carrier 25, and is supported thereinito have to and fro movement upon rollers 37 rotatably carried and separated by the carrier 36. At the rear side the slide section 17 rotatably carries a roller 38 with a portion thereof passing through a slot in the iiange 35 to engage with and run upon the upper flange 19 of the slide section 18. .The outward move- .the roller carrier 36 to take up the shockfas the stops engage with the carrier, similar to the cushions at the end of the carrier 25.

The inward movement is limited ...by a

downwardly extending portion 43 of the slide at the end engaging with a vdownwardly bent portion 26 of the uppei` flange of the guide 14 of the section 18 to form the slot for the passage of the roller 26.

The extension support sections 17, 18 are adapted to be releasably connected by a hooked latch 41 pivotally carried within the section 18 adjacent the rear and has a depending portion 42 to serve as a counterweight to maintain the latch in the normal position shown in Fig. 5. The hooked end of this latch cooperates with the downwardly extending portion 43 of the section 17, (Fig. 5) to lock the sections together whereby the two slide sections move concomitantly and' the slide section 17 with the connected drawer supported by the slide section 18 upon the rollers 24.

The operation is substantially as follows Assuming a drawer is in its normal position in a chamber in the casing and the parts in the positions shown in Fig. 5 with the extensible supporting slide rsections 17, 18 locked together by the latch 41,. As the drawer is moved outward the connected sections with the drawer will ride along the rollers 24 until the drawer is moved out substantially midway when the movement of the rollers will be arrested by the roller carrier 25 engaging with the stop 28. Si-

multaneously with the engagement of the roller carrier with said stop the depending portion 42 of the latch will engage with the end of the roller carrier throwing the latch 41 out of engagement with the portion 43 of thev slide section 17 releasing the slide sections. The drawer at this time is substantially in the position shown in Fig. 7 and it will be noted that the drawer at this time is and has been during its outward movement up to this point supported substantially centrally thereof upon the rollers 24, 24 with the load equalized upon said rollers, the weight and load of the drawer at the forward end causing the roller 26 to enga-ge with the upper flange or runway of the guide 14 and preventing any frictional retardation of the movement of the drawer which would otherwise occur should the .lide section 18 be in slidiri'g and frictional contact with said runway of the guide. The slide section having been released the drawer during the further outward movement will be supported upon the rollers 37 running' upon the flange or runway 20 of the slide section 18, and will be supported upon said rollers to its outermost position, any weight upon the forward end of the ldrawer causingv the roller 38 to engage with and run upon the upper/runway or flange 19 of the slide section 18 thereby -overcoming frictional retardation of the outward movement of the drawer. The outward movement of the drawer is limited by the forward end of the roller carrier 36 engaging with the stop 39 and the stop 40 engaging with the rear end of the roller carrier 36. The drawer will also be supported upon the rollers 37 during theinitial inward movement of the drawer to substantially its midway position 'into the casing when the part 43 riding 'over the hook 41 will lock the two slide sections together and such part 43 engaging with the downwardly extending portionl'26 .of slide section 18 will move said latter section rear-` ward with the movement of the drawer, the drawer being supported upon the rollers 24 during this movement through the slide section' 18 the same as during the initial outward movement of the drawer.

In Figs. 8 and 9 there is shown a modiication of the slide section to which the drawer is removably connected and consists of a member 17 bent longitudinally and .substantially centrally thereof at right angles', as at 44, to constitute a runway to support said slide section upon the rollers 37, the portion 45 below said angle portion being adapted to interlock or interengage with the slide section 18 to engage in back of the roller carrier 36 and thereby prevent lateral displacement of the slide sections. This slide section 17 also has stops coperat-ing with the slide section 18 to limit the to and fro movement of the slide sections relative to each other, and means with which the latch 41 coperates to lock the sections together. The section also has at opposite ends portions 46, 47 bent at right angles and in opposite directions, the angle portion 47 to, engage with the back of the drawer and the portion 46 with the extending end of the front wall of the drawer. To releasably connect the drawer to the slide the drawer has clips 48 on the side wall to vengage over and in notched portions'ofI the slide. Theseclips in the use of a metallic structure may be' stamped `out directly from the material of the drawer, and in the use of a wooden structure are secured to the side of a drawer as shown.

Each of the roller carriers 25 and 36 carries within the channel thereof a pad 40 (Figs. 4 and 5) to extendv longitudinally thereof, and which 'preferably consists of strips of felt carried by said carriers and runways and carrying a roller at the rear' end to engage with the upper runway of the guide; rollers and a carrier therefor in the guide and upon which rollers said slide is supported upon the lower runway of the guide; a slide to which the drawer is con# nected engaging in the first slide and carrying a roller at the rear end to engage with the upper runway of said first slide; and rollers and a carrier therefor in the first slide upon which rollers said second slide is supported upon the lower runway of the first slide, substantially as and for the purpose specified.
