KENNEDY, F LONG BEACH, CALIFORNIA, ASSIGNOR 0F ONE-THIRD TO WIL- LIAM FRANCIS KENNEDY, OF LOS ANGELES, CALIFORNIA, AND ONE-THIRD TO JANICE CAROLINE KENNEDY, OF LONG BEACH, CALIFORNIA ROLLER BEARING DRAWER some Application filed February 12, 1930. Serial 170.427,?98.

My invention pertains to roller bearing drawer guides and the construction of drawers utilizing such guides.

In the installation of sets of drawers in 1 built-in features, it is customary to reduce the guide bars for the drawers and have single fixed bars at the bottom and top of the drawer. In the ordinary practice the drawers are made to have a rubbing contact with these guide bars, but with such construction the drawers cannot be maintained properly aligned and considerable friction has to be overcome to operate the drawer and frequently they become. so much out of in alignment as to jam and prevent operation. .An object therefore of my invention is the employment of roller bearing guide elements to cooperate with the guide bars. These elements are, preferably attached to the inner part of the drawer and guide the drawer on both the upper and lower guide bars. This construction maintains the rear part of the drawer always in proper alignment with the drawer opening in the face of the 2b fixture. In this connection another detailed object and feature of my invention is forming a roller guide for the bottom rear part of the drawer, such guide having a plate or the like attachable to the back part of the drawer and this plate has a single roller operating on a horizontal axle, the roller bearing 'on the top of the lowermost guide bar and there being two vertical rollers on vertical studs engaging opposite sides of this lower guide bar. Such construction therefore supports the inner pair of drawers slightly above the guide bar and the drawer is guided both as to lateral and to a certain extent vertical 4 displacement. Cooperating with this I preferably use an upper guide roller secured to the upper inner part of the drawer and bearing against the upper guide bar. This roller is mounted on a horizontal axle and thus with the lower horizontal roller restricts up and down motion of the inner part of the drawer and reduces the friction of movement. V i 1 Another object and feature of my invention isvthe employment of guide rollers secured inside of the wall fixture having the drawer opening and positioned to engage the opposite sides and the opposite lower edge of the drawer. Thus at the drawer opening in the fixture, the drawer is guided to reduce frictional resistance when passing through the drawer opening and the rollers facilitate the sliding action of thedrawer as well as maintaining the drawer properly centered. 1

My invention is illustrated in the accompanying drawing, in which,

Fig. 1 is a perspective view of a drawer in thedrawer guides, taken from the inward part .of the drawer;'

Fig. 2 is a perspective view, of one form of the guide roller mounting to engage the bottom guide bar;

Fig. 3 is a perspective view of the roller mounting to engage the upper guide bar;

Fig. 4 is a perspective view of one of the guide roller mountings to engage the side and the lower edge of the drawer;

Fig. 5 is a perspective view of a modified form of lower guide roller mounting to engage the lower bar.

In the drawing, a section of a wall fixture is'designated by the numeral 11. Thismay be a constructionhaving a series of drawers therein and the drawer opening is indicated by the numeral 12, such. opening being shown as rectangular. There is a lowerguide bar 13 and an upper guide bar 14; extending inwardly from the'inside face 15 of the fixture 11. These are illustrated as being rectangular as is the .ordinarycustom., ljhe drawer designated generally at 16 has an 111 ner end" 17 opposite side walls 18,.afront 19 and a bottom 20.

The lower roller mounting to engage the lower guide is indicated particularly inFig.

Oil

2 and designated by the numeral 21. This is shown as having a flat plate 22 with an upward flange 23, there being if desired a pair of slots 24 for securing screws. A pair of vertical studs 25 depending from the plate 22 have vertical rollers 26 thereon and secured to the flange 23 there is a bent strap 27. This strap has one portion secured to the flange 23 and has ears 28. An axle 29 extends between ihese ears and :..on "this axle there is .a rotatable roller 30. This mounting for the rollers is secured on the rear board 17 and on .the bottomof the drawer, in which case the plate 22.'fits against the hottom'20 of the drawer and the fian'gei28 against the back board 17.

The vertical rollers 26 engage .opposite sides of the lower guide bar 13 and the roller 30 engages the upper tsurface of this .bar. This construction holds the bottom of the drawer with a suflicient clearance above the guide bar t'o-allow free sliding.

The bearing mounting to engage the upper guide bar 14 is illustrated in Fig. 3 'and designated generally by the numeral 31. This has an anglep'late with a vertical'section32 and .a horizontal section 33. The vertical section has a slot 34 and perforations 35' to be engaged'by screws or securing devices. A U-shaped strap 36 has a portionsecured to the hor i'zontal seiction 33 *an'd'upstanding cars 37 *with an mile 38" between the ears and the roller 39 on the a-xle. This isse'cured to the inner board :19 ofthe 'drawer and preferably with the vertical plate section 32 on the inside of the drawer an'd' with the section-33 resting on the top'edge 'ofthe board 17 This brings the roller 89' intoenga'gem'ent with the undersurface of the upper guide bar 14.

The side and 'bottom fbe'aring mounting illustrated-in Fig. 4, is designated generally by the numeral 4:0. This has an angleplate with a flatsid'e 41 with screw hole perforations theretlrrough and 'is designed to fit against the inner surface-of the fixture llhaving the drawer opening. There is an inwardly bent section 42 which hasan extension 43 in alignment *withthe portion 42 and with laterally 'turned ears 44 withapin 15 therethrough and on this pin there is a roller 46. In addition there is aistrap47 welded or riveted to the portion 42 of the angle. This straphasan underneath bent portion 48 with 'a single iupturned "ear- 49, there being-a pin "50 :between this ear and the portion 42 of the angle' with the zroller 51 operating on the pin 50.-

There are two of these units-mountedion the inside of th'e fixture'Tl as illustrated in Fig. 1 so that the roller- 46 comes in contact'with the outside-of the sideboard 18'ofthe drawer adjacent the lower portion of this side board and with the roller 51 extending underneath the drawer-and operating on the under'sur face of the drawer. These pairs of rollers son opside of the board 17. There are a pair of vertical pins 55 dep'ending'from the portion 5%,eachpin having 'aroller 56 thereon. In

-.addition a .U-shaped strap 57 having ears '58is secured to the undersurface of the portion -5.4,'and a,pin.59 therethrough with a roller 60. When this construction is utilized thewerticalrollers 56 engage opposite sides of the guide harlfiand the roller 60 operates on the upper surface of :this guide bar.
