Claims.

My invention relates to a roller bearing mounting which, although adaptable to other uses, is more especially adapted for use in connection with the metal drawers of metal cabinets employed in domestic kitchens and has for its object the provision of an easily operable antifriction bearing for the cabinet drawers as well as a readily adjustable bearing adapted to compensate for'any undue play between the drawers and the cabinet walls.

The invention also for its object the provision of a thrust bearing whichmay be regulated and the desired amount of tension on the drawer obtained for the purpose of controlling the movement of the drawer.

The object and advantages of my invention will all be readily comprehended from the following detailed description of the accompanying drawing, wherein:

Figure 1 is a detail perspective view of a portion of one wall of a cabinet provided with my improved bearing and a portion of a drawer and trackway; the forward end of the drawer and trackway being broken away to disclose'the bearmg. a

Figure 2 is a perspective view of a portion of the cabinet side wall and drawer guideway and bearing with drawer removed.

Figure 3 is a horizontal sectional view through the cabinet side wall with the roller bearing and one side of a drawer.

Figure 4 is a cross-sectional view taken on the line 44 of Figure 3.

My invention relates to a bearingand guideway for the metal drawers of sheet metal cabinets; and although the invention is especially designed for kitchen cabinets, it is apparent that the invention is adaptable to other uses.

In the particular exempliflcation the forward portion of one side wall of a cabinet is shown at Ill, made of sheet metal and bent into the boxlike or column forming portion H. Disposed horizontally on the inner side of the wall If! is a bearing holding track or guideway 12 consisting of a preshaped metal strip formed with a flange l3 along its lower longitudinal margin and with a longitudinally extending shoulder portion M at a slight distance from the upper longitudinal edge of the strip. The forward end of the strip is shown secured to the column portion of the cabinet by means of screws If); it being understood that the rear end of the strip or trackway is also secured in place so as to maintain the trackway in horizontal position.

ficiently spaced apart to provide a channel therebetweenfor reception of the roller bearing and the guideway which is attached to the drawer, as willbe hereinafter described.

The track forming strip I2 at a predetermined distance from its forward end preferably is provided with vertically spaced partially severed portions which are bent inwardly toward the rear side of the track strip to provide a pair of off-set tongues l5, 16 whereby the rear end of the bearing carrying metal plate I1 is clamped in place as shown in Figure 3; and the forward end of the track strip [2 is provided with an opening l8 for passage of the roller bearing l9 therethrougha The roller bearing I9 is of cup-shape and .interiorly provided with a race-way 2-9 for the ball-bearings 21 which are held in place by the pin 22 provided at its outer end with a head while the inner end is reduced and secured to the metal plate ll; the bottom or inner vertical face of the cup-shape bearing 1 9 being provided with a hole somewhat larger'than the head of the pin 22 so as to be out of frictional engagement with the pin .22.

The metal plate I1, adjacent its inner end, is provided with a transverse crimp 24 to provide a fulcrum point. for the metal plate whereby the forward or roller carrying end of the metalplate is normally forced away from the track member l2; while the forward end of the metal plate a short distance from the roller bearing has an opening punched therein so as to leave sufficient metal, as at 25,.to effect screw-threaded relation with the set-screw '26 which loosely extends through a hole in the track member I2. As is apparent from thevconstruction shown in Figure 3, the forward end of metal plate ll may be positioned close to or farther away from the track member l2 upon suitable rotation of set-screw 26 and thereby control the extent to which the roller bearing I9 extendsthrough the track member and hence into lateral relation with the vertical face of the channeled guide strip 21 secured lengthwisely on the side wall 28 of the drawer 29.

The guide strip 2! is shown provided with an outwardly disposed fiange-3ll at its lower longitudinal edge which extends beneath the bottom of the'drawer 29 and is secured thereto; and this strip, slightly removed from its upper-longitudinal edge, is channeled outwardly as shown at 3| to have sliding engagement with the top of the roller bearing IS; the channeled portion 3| fitting between the top of the roller bearing IS The lower flange l3 and the shoulder M are sufand theoutwardly disposed corrugation or shoulder Id of the track member I2, see Figures 1 and 4, so as to support the forward end of the drawer on the roller bearing l9 and provide a non-friction sliding relation between the drawer and the cabinet walls with the Weight of the sliding drawer transmitted to the roller bearing.

In order to prevent vertical shifting movement of the forward or roller carrying end of the plate I1, I prefer to flange the upper and lower longitudinal edges of the plate I! as shown at 32 with the flanges in overlapping relation with the outwardly disposed portions of the track member [2, see Figure 4.

With the guide member 2! flanged at its bottom and the flange 30 secured to the bottom of,

the drawer 29, it will be noted that smooth uninterrupted surfaces are presented toward the track member [2 and to the roller bearing I9 and easy operation of the drawer is provided.

In the event of too great lateral play between the sides of the drawer and the side walls of the cabinet, the spaced relation between the roller carrying plate I! and the track member l2 may be altered by properly screwing the set-screw 26 so as to cause the roller l9 to be moved out- Wardly toward the side of the drawer; the flat surface of the roller bearing l9 and enlarged head of pin 22 thus constituting a thrust hearing adapted to take up the lateral play of the drawer. It it also apparent that the freedom of sliding movement of the drawer may thus be regulated in keeping with the wishes of the user; the axial depth of the roller being such that more or less in and out movement of the bearing may be had and still present sufficient bearing surface for the channeled or shouldered Portion 3| of the drawer guide strip 21'.

The upper surface of the corrugation or shoulder portion H! of the track member 2 is shown with an upwardly disposed offset portion 33 (see Figures 1 and 2) adapted to engage a suitable struck-up lug or pin 34 on the rear end of the guide member 21 which prevent the drawer being drawn completely out of the opening in the cabinet; and in order to prevent the drawer, when pushed inwardly, from making forcible contact with the rear wall of the metal cabinet, I prefer to provide the channel portion of the track member [2 with a struck-up portion 35 disposed in the path of the channeled portion 3| of the guide member 21 and thereby prevent further inward movement of the drawer.

I have shown what I believe to be the simplest embodiment of my invention which I have described in terms employed for purposes of description and not as terms of limitation, as structural modifications may be made without, however, departing from the spirit of my inven tion as defined in the appended claims.
