I f "Application october 16, 1950,;Seri al No. 190,326-

The present invention relates to a novel roller bearing drawer guide, and is an improvement directed to simply, economically and effectively providing rollers for elimination of friction in the structure of drawer guide, shown inimy Patent No. 2,519,623, granted August 22, 1950.

It is a primary object and purpose of the present invention to providethe novel drawer guide structure with rollers for eliminating friction for e of m emen s? ll1' lid 1 guides, Whether h Wal 6. 1.15 em 9- T... to provide a novel s tructure ofroller mounting in connection with the drawer guide which, when assembled in place securely holds and retains the rollers against disengagement, though in the assembly each roller is merely slipped over the free end of a bearing pin to carry the roller, and such free end of the bearing pin is neither enlarged by riveting, upsetting or otherwise, the roller being retained and held against disconnection from the bearing pin through entering a retaining slot in a part of the drawer guide on which it is mounted.

An understanding of the invention may be had from the following description, taken in connection with the accompanying drawing, in which,

Fig. 1 is a side elevation of the drawer guide of my invention showing the movable member thereof partly withdrawn.

Fig. 2 is a fragmentary enlarged elevation, with parts broken away and shown in vertical section, illustrating one of the rollers and its mounting and the retaining slot through which it passes, and

Fig. 3 is a vertical section substantially on the plane of line 3-3 of Fig. 2.

Like reference characters refer to like parts in the different figures of the drawing.

In the structure of the guide, a length of sheet metal is formed into a generally Z-shaped form, having a vertical leg I, at the lower edge of which is an integral web 2 extending horizontally for a distance, and continued in a downwardly extending leg 3 in a vertical plane ofiset from the leg I, at its lower end portion being bent into a U-bend 4, the drawer guide member terminating in an upwardly extending leg 5 spaced from and parallel to the leg 3 with its upper edge being located a short distance below the web 2 as shown in Fig; 3. Such drawer guide member may be secured, one at each side of a drawer and at the outer side thereof, though it is to be understood that the attachment of the drawer guide members, one at a side of the drawer and the other at a side of the case or cabinet which 3 cla (chaos-3.3

receives the drawer, may be reversed without changing the principle of operation of the structure.

' flhe cooperating drawer guide member is of a substantially similar structure havinga vertical leg 6, similar to the leg I, from the upper edge of which an integral horizontal web I extendsfor a distance and is then extended upwardly in a leg 8, at the upper end of which is an inverted U-bend 4a, and continued from which is a terminal leg Q'spaced from and parallel to the leg 8. Such drawer. guide members are assembled together by sliding one at one end 'wi'thi'nthe other, with the leg 5 received between the legs 8 and 9 and the leg 9 between the legs 3 and 5.

The leg I adjacent its inner end is provided with a roller I0 and the leg 6 adjacent its outer end with a roller I I. The upper roller I0 and the lower roller II extend through slots I2 made in the webs 2 and I, the lower portion of the upper roller I0 passing through the slot in its adjacent web 2 for bearing engagement against the inverted U-bend 4a. The lower roller II extends at its upper portion through the slot I2 for bearing engagement against the U -bend 4.

Both rollers are mounted upon fixed bearing pins I3 which are permanently secured to the legs I and 6. Such legs I and 6 have openings to receive reduced end portions of the bearing pins, such reduced end portions after passing through such openings being headed over by riveting as shown in Fig. 3.

In the assembly of the rollers with the drawer guide members they are placed over the outer or free ends of the pins I3, the rollers entering their respective slots I2 in the webs 2 or I and the reduced end portions of the pins I3 passed through the openings in the legs I and 6 and permanently secured by rivet heading over of the free ends of such reduced portions. This maintains the rollers I0 and II against disconnecting with respect to the bearing pins I3 on which they are rotatably mounted.

It is evident that the rollers I0 and II will ride against the U-bends of the drawer guide members on which they are not mounted. For assembly with a drawer, having the legs I permanently secured thereto, when the drawer is moved outwardly the lower bends 4 will bear upon the rollers II and the rollers I0 upon the upper U-bends 4a. If the weight of the drawer at an outer position is such that the center of gravity of the drawer and its contents is moved out beyond the axis of rotation of the rollers II, the rollers I0 may be lifted slightly and the upper edges of the.

legs 5 irictionally bear against the inner sides of the upper U-bend 4a, this having a beneficial eifect in checking outward movement of the drawer so as to slow down such movement when the drawer is approaching its outermost position.

The structure described is very practical and useful and is of an especially economical structure and one made at low cost.

The invention is defined in the appended claims and is to be considered comprehensive or all.

forms or structure coming within their scope.

I claim:

1. A drawer guide structure comprising, an upper horizontal member having an upper vertical leg, a horizontal web extending at right angles therefrom at its lower edge, a second vertical leg extending downwardly from the web and C911! tinued in a return U -bend and terminating in a at one end to the vertical leg of the member which terminal vertical leg spaced from the second mentioned vertical leg, alower member having a vertical leg, a horizontal web extending therefrom at right angles at its upper edge and a sec-' and vertical leg on the lower member extending upwardly from said horizontal web alongside the terminal leg of the first member, said last mentioned vertical leg of the second member being continued in an inverted U-bend, and terminating in a downwardly extending vertical leg located between the second mentioned vertical leg and the terminal leg of the first member, each horizontal web having an opening therethrough, and a roller mounted to turn on a horizontal axis carries it, and havin a free end portion extending through its associated roller and over which said roller is adapted to freely pass, said rollers being maintained in position against disengagement from said bearing pins by the portions thereof extending through the openings in the horizontal webs of the members on which mounted.
