7 Claims.
This invention relates to guide shoes for vertically sliding fireproof elevator doors. It has for its principal objects to devise a simple, economical and efiicient guide shoe which can be readily secured in place and adjusted to obtain the desired play between the door and the door guides, which will facilitate replacement of worn parts, and which will prevent binding of the door when the door guide and parts cooperating therewith expand due to heat in the event of fire. The invention consists principally in the improved door guide construction and in the combinations and arrangements of parts hereinafter described and claimed.
In the accompanying drawing, which forms part of this specification and wherein like symbols refer to like parts wherever they occur,
Fig. 1 is a horizontal cross-section on the line l-l in Fig. 2 through the adjacent side frame members of an elevator door guide construction embodying my invention,
Fig. 2 is an interior, fragmentary side elevational view of the parts shown in Fig. 1,
Fig. 3 is a vertical section on the line 3--3 in .Fi
Fig. 4 is a view similar to Fig. 2 with one of the adjustable plates removed to disclose the combustible shim,
Fig. 5 is a view similar to Fig. 2 showing the position of the guide plate when the combustible shim becomes disintegrated due to fire,
Fig. 6 is a view looking at the inner face of the adjustable guide plate,
Fig. 7 is a perspective view of a bearing plate for the adjustable guide plate; and
Fig. 8 is a perspective view of the combustible shim.
The accompanying drawing illustrates my invention in connection with a fireproof elevator door construction comprising a metal clad closure or door section A arranged for sliding movement across the door opening B in an elevator shaft. As shown in the drawing, the door section A is provided along each vertical edge with an angle bar side. frame member C, whose outstanding flange l is slidably arranged between the spaced parallel flanges of angle bar guides D and E, which are rigidly secured together and to the adjacent jamb member F of the door opening. This elevator door construction is well known and it is considered unnecessary to illustrate it in detail. Mounted on the free outstanding flange I of the door angle is a guide shoe comprising a metal inner plate 2, which bears flatwise against said flange and overlaps the adjacent side face of the free outstanding flange 3 of the guide 1 extend horizontally through circular holes 8 provided therefor in the inner guide plate 2 and through elongated oblique slots .9 and it provided therefor in the outer plate 4 and shim li, respectively, and are provided at their outer ends with nuts H and suitable lockwashers I 2. As shown in the drawing, a bearing plate It extends from stud to stud between outer guide plate 4 and the lock washers E2, the studs extending through holes provided therefor in the ends of said bearing plate.
The side of the rib remote from the edge of the flange 3 of the guide angle E is provided opposite the inclined slots 9 and Ill, with similarly inclined surfaces l4 adapted to slidably engage similarly inclined surfaces IE on lugs I ti formed integral with the inner guide plate 2 of the guide shoe. As shown in the drawing, the slots 9 and I0 and the cooperating surfaces 14 and i5 slope downwardly and outwardly away from the vertical edge of the free outstanding flange 3 of the 1 guide angle, whereby the bearing rib 5 of the outer guide plate moves toward said edge of said flange when the guide plate is moved upwardly and away from said edge when the guide plate moves downwardly.
By the arrangement described, the outer guide plate 4 of the shoe may be readily adjusted to take up wear and to secure the desired play between the bearing rib 5 thereof and the Vertical edge of the free outstandingflange 3 of the guide angle E by raising or lowering said plate, after which said plate may be locked in the desired position of adjustment by tightening the nuts I I. The adjustable guide plate 4 is preferably made in the form of an iron or steel casting and the plate l3 against the outer surface thereof is preferably made of galvanized metal so as to prevent binding or sticking of the two plates due to rust.
2 ment thereof, said plate can be replaced separately and conveniently. In the event of fire, the effect of heat will cause the fiber shim 6 to burn out or become disintegrated, thereby freeing the outer guide plate from the clamping action of the nuts ll, thereby permitting said plate to drop downwardly and away from the longitudinal edge of the free outstanding flange 3 of the guide rail E at an oblique angle corresponding to the inclined surfaces IS on the inner guide plate 2 and thus prevent binding of the door when the metal parts of said door expand due to such heat.
What I claim is:
1. The combination with a frame member and a sliding closure member therefor, of a guide for the sliding closure member comprising two separate guide plates mounted on one of said mem bers and overlapping the opposite side faces of said other member, one of said guide plates having a portion disposed opposite the adjacent edge of said other member, said guide plates having cooperating inclined surfaces adapted upon relative movement thereof to vary the space between said edge of said other member and said portion of said last mentioned guide plate.

The combination with a frame member and a sliding closure member therefor, of a guide for the sliding closure member comprising two separate guide plates mounted on one of said members and overlapping the oppositeside faces of said other member, one of said guide plates having a portion disposed opposite the adjacent edge of said other member, said guide plates having co operating inclined surfaces adapted upon relal5 of the lugs tive movement thereof to vary the space between said edge of said other member and said portion of said last mentioned guide plate, means for clamping said plate in the desired position of adjustment, and means for rendering said clamping means inoperative when said door guide is exposed to fire, said last mentioned means comprising a combustible shim interposed between said plate.
5. The combination of a frame member and a sliding closure member therefor, of a guide for the sliding closure member comprising two separate guide plates supported on said closure member and overlapping the opposite side faces of said frame member, one of said guide plates having a portion disposed opposite the adjacent edge of said frame member, said guide plates having cooperating inclined surfaces adapted upon relative movement thereof to vary the space between said edge of said frame member and said portion of said last mentioned guide plate, a combustible shim interposed between said guide plates, and means for clamping said guide plates and shim together and to said closure member, said means comprising spaced studs fixed to said closure member and extending through openings provided therefor in said guide plates and said shim, and nuts on said studs.
