ROLLER MOUNTING Filed July 25, 1945 IN V EN TOR.

Patented Oct. 17, 1950 ROLLER MOUNTING Roy A. Stone, Rockford, Ill., assignor to National Lock Company, Rockford, 111., a corporation of Delaware Application July 23, 1945, Serial No. 606,502

This invention relates to rollers designed for use as the supporting rollers for the sliding drawers or trays of kitchen cabinets, stoves, refrigerators and the like.

Articles of furniture of this type usually have the tracks or slides made of metal, and in many instances they are enameled or provided with some type of finish. The supporting rollers have been customarily carried on pintles which were riveted to the supports. If attached to the supports prior to enameling or finishing, the rollers themselves became coated, which interfered with their operation, and, if mounted subsequently to the finishing, the riveting operation chipped the enamel and marred the finish of whatever type.

The primary purpose of my present invention is to provide a supporting roller of the character indicated which can be mounted on a previously enameled or otherwise finished article without injuring such finish, and which can be easily installed and by unskilled labor and without the employment of tools or gadgets of any character.

The advantageous features of my invention will be readily appreciated as the same becomes better understood by reference to the following description when considered in connection with the accompanying drawings.

Referring to the drawing,

'Fig. 1 is a side elevation of a roller embodying my invention and shown as mounted in operative position;

Fig. 2 is a plan view thereof;

Fig. 3 is a bottom view thereof; and

Fig. 4 is an elevation exemplifying the manner of mounting the roller.

On the drawing reference character Eindicates a supporting member, such as a stationary channel or angle bar, serving as a support for a slidable drawer or tray 5 or the slide. therefor. A

plurality of rollers constructed in accordance.

with my invention are employed for anti-friction purposes between the relatively

movable parts

5 and 6. i

The roller as illustrated comprises a sheet metal body and a roller wheel journaled therein so as to project beyond the plane of the body 4 Claims. (cine-6) l 2 the pintle without the bearings.

The central portion of the top wall of the frame is cut away to permit a segment of the roller to project above the frame, as shown in Fig. 1, and the end portions of this top wall are longitudinally extended to provide wings or projections l2 and I3 adapted to overlie the margins of an opening 14 formed in the member ii to receive the frame.

Immediately beneath the wing l2 the

side walls

7 and 8 are provided with a notch 15 adapted to receive an end wall of the opening M. The other wing I3 is continued into a down-turned extension [6 shaped to provide an integral latch formed by a locking shoulder l1 and an inclined surface l8 adapted to be inserted through a small opening 19 formed in the member 5, and to engage the margin of the member 3 at the opening l9, as shown.

In mounting the roller in the supporting member 5 the frame is slid into the opening l4 until it assumes the position shown in Fig. 4, with one end wall of the opening engaged in the notch l5, whereupon the other end is pressed downwardly to'force the extension l6 through the opening 19 until the shoulder I] engagesthe margin of the opening beneath the member 5 The resiliency of the sheet metal of which the frame and extension are formed causes the shoulder I! to act as a latch for retaining the roller frame against displacement from the opening l4. Should it be desirable to remove the roller from the support for purposes of repair or replacement, this can be easily accomplished by raising l the lefthand end viewing Figs. 1 and a, of the frame to withdraw the locking extension from the opening l9. Unless positively lifted out in this manner, the roller will be retained in mounted position and snugly held in its mounted position against rattling or vibration during use.

It will be apparent from the foregoing that I have provided a simple roller mounting which requires no tools for its assembly, but which can and carry the movable member. The sheet metal frame is made from a single piece of metal bent into substantially inverted U-shape to provide side members 'i and 8 between which the roller Wheel 9 is mounted upon a pintle H. The roller may be of metal and mounted on ball or roller types of hearing, or it may be of plastic, wood, or other suitable material, journaled directly upon be snapped into position by engaging the notch I5 with one of the openings in the support and pressing the other end of the frame downwardly to force the yielding extension l6 through the opening l9; The mounting may, therefore, be assembled after the supporting members have been finished and the assembly operation will in no wise mar or injure the finishof the support.

The structural details illustrated and described may be varied considerably without departing employment of special from the essence of my invention as defined in the following claims.

I claim:

1. In a mounting for a mechanical device, the combination with a support provided with a large opening and a small opening, of a devicecarrying frame mounted in said large opening, said frame being notched at one end to receive one end wall of the large opening and provided at its other end with a depending latch member adapted to be engaged with said support to hold said frame against displacement.

2. A roller mounting, comprising a frame provided at one end With a notch and at its other end with an extension terminating in a depending resilient latch member adapted to be engaged with a support to hold said frame in mounted position, and a roller journaled in said frame.

3. A roller mounting, consisting of a roller, a frame in which said roller is journaled, and a latch carried by one end of said frame and adapted to be engaged with a support to hold the frame in mounted position, said frame being provided at its opposite end with a notch adapted to receive the edge of an opening in a support in which said frame is mounted.

4. A roller mounting, comprising a frame formed of sheet metal bent into substantially inverted U-shape, a portion of the connecting wall of said frame being removed, a roller mounted in said frame and projecting above said connecting wall, the frame being provided at one end with a notch, an extension at the other end of the frame, and a latch member depending from said extension and adapted to yieldingly engage a support upon which the frame is mounted to hold the frame against displacement.

ROY A. STONE.
