EDMOND PRUDHOMME AND PANTALEGN MOSES LEPROHON, OF

NEW YORK, N. X.

Leners Patent No. 90,193,1zated May 1s, 1869.

MROVED SLIDIN G- DOOR To all whom itmay concern:

Be it known that we, EDMOND PnUDHoMME and PANTALON Moses LEPROHON, of the city, county, and State of New York, have invented a new and useful Improvement in Sliding Doors; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference `being had to th'e accompanying drawings, forming part of-this specication, in which- Figure 1 represents a face View, partly in section, of our improvement in sliding door.

Figure 2 is an edge view, partly in section, of the same. v l

Similar letters of reference indicate corresponding parts.

This invention relates to a new means for retaining sliding doors between their guides, even if they should shrink or settle irregularly or evenly; and has for its object to overcome the frequent annoyance resulting from the working of the upper dowel-pins out of the groove, or track provided for them.

The invention consists in providing rollers on the upper edges of sliding doors, said rollers being hung in frames or bars, that rest on springs, provided on or in the door, so that by means of these springs, the rollers are constantly held up against the upper frame, and retained in the groove provided for them.

lf the door or frame should shrink ever so much, the upper rollers will always be retained in their grooves, or .on their tracks, and the door will consequentlyalways be properly guided.

A, in the drawing, represents a sliding door;

B is the side frame, between which it moves;

C isithe rail, on which it rests; and

D is the upper frame or lintel.

Rollers a a are arranged on the lower edge of the door, to travel on the rail O. b b are rollers, hung, with their axles c, in the bifurcated upper ends oi' metallic bars E, which bars are, with their shanks d, iitted into mortises, provided in the upper edge of the door.

Springs e e are arranged in these mortises, to snpport the bars E. By these springs the rollers b are held constantly against the lintel D, in the groove, or on the track provided for them, and if the door or frame should shrink `or settle, the rollers will adjust themselves up or down as they travel along under the lintel.

The door can thusnever work itself laterally out of the frame.

Having thus described ourinvention,

What we claim as new, and desire to secure by Letters Patent, is-

The rollers b, supported upon the springs e, in the upper end of a sliding door, substantially as described, for the purpose specitied.
