ROLLER FOR SLIDING DOORS.

SPECIFICATION forming part of Letters Patent No. 330,339, dated November 10, 1885.

Application filed February 3, 1885. Serial No. 154,812. (No model.)

To all whom it may concern:

Be itknown that I, NOAH LUCAS, of the city of Norwich, county of New London, and State of Connecticut, have invented a certain new and useful Improvement in Rollers for Sliding Doors,whichimprovement is fully set forth and described in the following specification, reference being had to the accompanying drawings.

This invention relates to anti-friction rollers used to support and guide sliding doors, my immediate object being to provide rollers which will be comparatively noiseless, and which may be produced without adding materially to the cost.

In the accompanying drawings, Figure 1 is a view of a portion of a door suspended on one of my improved rollers. Fig. 2 is a vertical cross-section through the center of said roller, (somewhat enlarged,) and also shows the form of track or guide-rail used.

The method and means for securing my roller to the sliding door and operating the same are substantially the same as in the de vices now in common use-that is to say, said roller rotates on a stud secured to a metallic bracket, which in turn is secured rigidly to the sliding door.

My invention consists, in brief, of providing a flexible or yielding tire which encircles each metallic roller and is so shaped that the metal roller and the guidetrack in which said roller travels are kept at all times from contact with each other by said intervening flexible tire.

Referring to the annexed drawings, a represents a rolleror pulley; 12, its pivot or axle,

and 0 my flexible tire, held in an annular groovein the periphery ofsaid roller,as shown.

d is a rail, of metal or other suitable material, havinga semicircular longitudinal groove in which rests and travels the rubber tire c.

It will now be evident that as the door is moved to open or close it the tire 0 will follow said grooved rail, but as the metallic portion of the roller is thus kept from contact with said rail no noise is made.

The value of my invention will be especially apparent when applied to sliding doors in dwelling houses, where the slightest noise causes great annoyance. This new form of roller can be used equally well with doors sus pended on an overhead track, as described, or with a ground-track, in which latter case said rollers may be concealed in the usual way in mortises in the door, if desired.

I am aware of the patent to R. G. Hatfield, No. 38,387, dated May 5, 1863, and do not, therefore, broadly claim a rubber-tired roller.

What I do claim 1's The combination of a suitably-pivoted roller for sliding doors,having its periphery grooved, as shown, with an encircling tire of rubber adapted to fill said grooved roller, and a guidetrack of such size and shape that said roller may travel in and be guided by said track, but is held from contact with the pivoted. metallic roller, for the objects hereinbefore set forth.

NOAH LUCAS.
