DE WITT RAMSEY SLIDING DOOR MOUNTING Filed Sept. 25, 1946 QINVENTOR. DE. I/VJTT RAMSEY ATTD R N EYE Patented Dec. 28, 1948 2 Claims.

This invention relates to improvements in sliding doors, and more particularly to the provision of a three member header for use on sliding doors.

It is an object of the invention to provide roughening of the track surfaces upon which sliding plates of sliding doors move.

A further object is to provide in a sliding door, a longitudinal slide track which enables smooth cushioned operation by reason of peaked points leveling off to a true slidable surface with a minimum of friction by contact when being operated.

A further object is to provide a slide track in which self lubrication is given to the slidable surface and groves by impregnation with lubricant, so that as the slidable surface wears down, the gliding unit comes in contact with additional lubricant.

A further object is the provision of a track in which suction is eliminated by roughening the surfaces to allow air to pass between the small glidable surfaces; and in which each peaked glidable surface acts as an individual wiper keeping the metal hanger glide plates wiped clean at all times.

These and other objects are attained by the novel construction and arrangement of parts hereinafter described and illustrated by the accompanying drawings, forming a part hereof, and

in which:

Fig. 1 is an elevational view of a slidable door embodying the invention.

Fig. 2 is a sectional view taken on the line 2--2 of Fig. 4.

Fig. 3 is a sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a transverse sectional view of the device.

Fig. 5 is a sectional view taken on line 5-5 of Fig. 2.

Referring to the drawings, the device for sliding doors is shown to comprise a hanger blade I having flanges 2 by means of which and a screw 3 it is attached to a sliding door. Passing through the upper portion of the blade I is a pin 4 which rests upon a slide plate 5, which is dish shaped having upturned side and end walls. At the upper end of the blade I is a flange 5 upon which rests afiat band I of non-corrosive metal, having downturned ends 8, long and Wide enough to cover the inside dimension of the slide plate 5, the downturnedends being confined in the upturned portions of the slide plate 5.

The band 1 provides a slide surface of sufficient surface area to allow safe and smooth sliding without danger of digging and binding when the upper portion II of the sliding door track is made of soft wood, and when exceptionally narrow doors are used which might cause upward pressure on the sliding units if the door is improperly operated.

The slide plate 5 slides on roughened surfaces II) of lower tracks 8 and 9. in the form of grooves cut or embossed at right angles, diagonal or circular on or across the 1ongitudinal slide surfaces of the track members in such a manner as to form a series of small surfaces upon which the slide plate 5 will slide freely.

These surfaces are treated with penetrating or retained lubricant for automatic lubrication as wear occurs. In the treatment of the roughened surfaces, parafilne is applied with heat to cause penetration to giVe a satisfactory lubricant. Similar lubricating agents can be used. Hardwood is a suitable track material, and certain forms of composition and plastics may be used.

It will be seen that there has been provided a slide device for doors which has a flat plate 1 to prevent digging and the like as stated above; and also a self lubricating sliding surface which F enables smooth cushioned operation by reason of the peaked points leveling off to a true slidable surface with a minimum of friction by contact when being operated. Also, the roughened surfaces with the lubricant eliminates suction allowing air passage between the small slidable surfaces, and also the peaked surfaces act as self cleaners by wiping over the metal slides, all of which insures easy operation.

The above description is to be considered as illustrative and not limitative of the invention of which modifications can be made without de parting from the spirit and scope of the appended claims.

The invention having been described, what is claimed is:

1. A device for sliding doors that are adapted to be used with a support having spaced parallel lower tracks, comprising a hanger blade attached to a door, adapted to depend below and through said tracks, a slide plate slidable on the tracks and having a slot through which the blade passes, a pin passing through the blade and engaging the plate, a flange at the upper end of the blade, a fiat band resting on the flange and having downturned ends engageable within flanges on the plate.

2. In a sliding door, a hanger blade having a flange at its upper end, an upper track and two spaced lower tracks, a dish shaped slide plate with upturned sides and ends, and a flat band The roughening is resting on the flange and having downturned ends Nunfiber Name Date positioned in the upturned ends of the slide plate. 1,583,913 Brlncil May 11, 1926 said band being adapted to engage the upper 1,827,737 Coolidge Oct. 20, 1931' track. 1 1,882,956 Sandler Oct. 18, 1932 DE WITT RAMSEY 5 r 2,187,626 Merriman Jan. 16, 1940 2,286,573 De Witt Ramsey June 16, 1942 REFERENCES CITED 2,292,772 DeWitt Ramsey Aug. 11, 1942 The following references are of record in the F 5 Mel'z 1946 fi of this Patent 1 v 1 -FQ N AT NT UNITED STATES PA'I'ENT$ i 1 i I b Number Name 5 427,965 Great Britain Apr. 30, 1935 773,264 Roe Get. 25, 1904 I 1,002,514 Hatfield 1 Sept; 5, 1911
