.-. `aolims. e (o1. 454-77) V'This invention relates `vto` improvements ,fin drawer constructions'and particularly to the supticles, which devices are commonly known in the trade as drawer slides. The Vinventionv may be considered as an improvement over the construction disclosed in'my prior United `States vLetters Patent'No. 1,344,845, issued February 9, 1932.

An object of the present-invention is to provide an improved drawerslide consisting of a'rail, a

slide slidable thereon, which intu'rn slidably sup-l ports a drawer, tray, or similar-article.

`Specifically the inventionhas ast one of its objects the provision of suitable bumpers or devices formed of relatively soft material adapted` to vengage to limit sliding movement ofthe slideirela'- tively to the-rail and to limit sliding vmovement of the drawer relatively 'to the slide. These bumpers orl devices formed of soft material on engagement are relatively noiselelssso that when parts ofthe constructionreach thelimits'of their movement no undesirable .noise is produced thereby. l e .y

Another object of the -invention is" to provide aniimproved drawer slide construction having a rail and a'slide, the rail andslidebeing of such design as to be capable of easy manufacture andv .f

installation, at the same time being relatively sturdy to form a solid, supportxfor'a. heavily loaded vdrawer or" tray. Y

Another object of the invention is to provide ar drawer slide construction having a railv and a slide with a drawer slidable j on theslide,theconstruction being such as to enable the'drawerjto assume a tilted position with respect to the'slide. Such a `construction is frequentlyfound highly desirable in 4les and various other cabinets.

`Another object of the inventionv is to provide a suitable form of slide construction whichjcan be advantageously employed in ,conjunction with grates or trays conventionally' employed in re-` frigerators and like constructions, enablingy the grate or trayv to be completelyjwithdrawn from the refrigerator, supportedin yhorizontal ,positionV f by the slide, and caused to slide into the refrigerator when'desired..

With theforegoing andother objects in View, which will be made 4manifest in the following de#- tailed description, andspe'cioally pointed out ini the appended claims,reference` is had to theac-`` companying drawings foranyillustrative embodiment of the invention, wherein:

.Theftf 'operationl 'and advantages -of the above describedconstruction are as follows. In closing thedrawer from the/position shown in Figure 1, the draweris merelycaused .to slide rearwardly. v,Sliding 'movement rstu takes place between the e drawer andthe slide until'front wall`42ferigagesy blockl 39g esl-ides arethenforced rearwardly by thedrawer'and sliderearwardly o nlthe .rails ntil;lug,31"engages'bumper 21.

of thedraw'er from the 'chamber the drawer slidesA outwardly von the slides until stop blocks 4D engagel the rear ,ends of blocks 39after. which the slides are caused" to slide forwardly on therails until lugs 3E engage bumpers 25. f Becauseof. this arrangement and the .application Vof'bumpers-very littleif any noisefis produced on sliding the drawer-'forwardly 'or rearwardly. y

I have illustrated the twodrawers in Figure 1 asbeirig separatedby a division strip 45 but the use of this division"'strip is notnecessary anclmayv4 be completely* omitted, in which event each drawer'is supported solelyby its rails'and slides on lthe 'side-walls vII of the drawer receivingv chamber. The ,top'offront `wall 4 2 of the lower draweris. preferably so arranged as to fitl snugly 'of the front wall 42 of 'the .up-.L

Figur'e. The. slides 52 are of substantially the same construction illustrated in Figure l'with'the exception that at the forward endsof these slides' instead of having clip 38and Vrubber'lolock 39 it. ismerely `an',.upstanding lug 1,53, fseef Figure '7,

whichis" integral'with the bottom or horizontal portion yof theslide; The drawer employed has sides 54, afrontmwallf55, abottoml 53 disposed above the b'ottom.of the sides 54 and"fron`t wall ,55, and a rear wall 51. Rear wall 5l isdisposed ferirefglyef the reeredsef heiem 56, were@ zoy frontali portions p `andhorizontal-portions of the rails, the `vertical rear ends'l or sides'll arerounded, as'in'dicated at; Stopblocks'S arefastenedto the bottom 55' near the side walls lland are-adaptedto enlgage `lug 53.

In` this construction when! the drawer is withdrawn into substantially fully with-V drawn position it is possible to tilt thedrfawer into 'the position' shown. On swinging the drawerxback into horizontal position it may be vcaused to slide into drawer receiving chamber 58; rst sliding on the vslide and then causing slide 2 to sliderearwardly on 'rail' 5i.y Y

vInthe modification shown in Figure Bthere is illustrated a refrigerator, the interior'oflwhich constitutes .a 'tr'ayireceiving chamber G. Rails 5i are secured to the sides of chamber G0, these rails being of the same construction previously f described in conjunction with Figure 3. The slides 82 are of substantially the same construction as disclosed in Figure 4 except that the rubber block 3S and clip 38 are omitted and in place thereof a pin 63 projectsinwardly from the vertical portion of the slide.` The grate or tray is indicated at 64% and has rods 65' secured thereto which are bent downwardly, forwardly and then upwardly, providing runners 56. Runners G6 are connected to the body of thetray by suitable struts or posts 6l and the rear ends of the runners are bent upwardly behind the pins 63. In

this construction it is possible to slide the tray on its runners forwardly, sliding movement taking place on the slides G2 until the pins `63 are engaged by the upwardly bent ends at the rear ends causes the slides t2 to 'be carried rearwardly by the tray and to slide rearwardly on rails 6 i.

In all modifications the hooks 2l -on the rails hold the slides in horizontal position so that althoughv considerable weight is placed on the forward ends of the slides they cannot tiltrelatively to the rails. l j

From the above described constructions it will be appreciated that an improved drawer slide construction is provided having several advantageous improvements incorporated therein rendering the slide virtually frictionless in operation and virtually noiseless. that both the rail and the slide can be constructed each of a single piece of metal and the bumpers and 21 and the block 39 which are formed of softer material applied thereto.

Various changes may be made in the details of construction without departingfrom the spirit or scope of the invention as defined by the appended claims. y
