STAY-ROLLER FOR SLIDING DOORS.

SPECIFICATION forming part of Letters Patent No. 308,177, dated November 18, 1884.

Application filed Jun To aZZ whom it may concern.-

Be it known that I, EMIL LAASS, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Stays for Suspended Sliding Doors, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of doorstays employed for guiding the bottom portion of a suspended sliding door.

The object of the invention is to provide a door-stay which shall be adjustable so as to adapt it for use in connection with doors of different thicknesses without changing the position of the guide-roller on its sustaining-arm, thus obtaining a more secure support for said roller.

The invention consists, essentially, in the combination of an attaching-plate, an arm device forretaining the arm in its position, and a bearing on the free end of the arm engaging the door, all as hereinafter more fully described and set forth in the claims.

In the annexed drawings, Figure I is an edge view of the bottom portion of a suspended sliding door guided by my improved door-stay. Fig. II is a front view of my i11- vention. Fig. III isa plan View of the same. Fig. IV is a plan view of a modification of the construction of the attachingplate. Fig. V is a side view of the stay-arm to be used in connection with said attaching-plate, and Fig. VI illustrates a modification of my invention. D denotes thebottom portion of a suspended sliding door.

B represents the attaching-plate of the doorstay, said plate being rigidly secured in any suitable and Well-known manner to the side of the building beneath the bottom edge of the door.

A is an arm pivoted or hinged on the plate B in such a manner as to allow the free end of said arm to be swung laterally. The plate B is provided with a serrated, corrugated, or notched surface, a, which may be either on top or on the edge of a projection, 12, on said plate,

j ection b, as illustrated in Fig. IV of the draw by corresponding serrations or corrugations on said arm engaging with those of the projection b or eye 6, as shown respectively in Figs. I, II, III, and IV of the drawings, or by a pin, 8, which may be either integral with the arm A or inserted removably in an aperture in said arm, and engages with one of the series of notches in the edge of the projection 12, as shown in Fig. VI of the drawings. By means of either a key or nut on the end of the gudgeon d, the arm A is clamped on the attaching-plate. The free end of the arm A is provided with a pivot, f, for the roller R, which bears on the door to guide and steady the same in its movement. The pivotal pin f may be either made integral with the arm A and the roller journaled on said pin, or the pin may be affixed to the roller and pivoted on the arm. In either case the said pin is maintained in one position and always at a uniform distance from the attaching end of the arm during theadjustment of said arm required to bring the roller to bear on doors of different thicknesses. Vhen it becomes necessary to adjust the arm A, as aforesaid, the clamping device which fastens the arm on the attaching-plate is to be loosened or removed. and either the arm is to be raised to liberate the serrated or corrugated bearings or the pin 8 is to be withdrawn from the notch a in the projection 22, (shown in Fig. VI of the drawings,) then after swinging the arm A laterally until the roller B touches the door, the arm 0 is to be again clamped on the attachingplate, and is thus retained in its required position.

It is obvious that an angular or polygonal gudgeon, d, on the arm A entering a corre spondingly-shaped eye, 6, in the attachingplate, will answer the purpose of the hereinbefore-described devices for locking the arm A in its position; hence I do not limit myself to any specific form of said locking device.

that I- claim as my invention isas shown respectively in Figs. I, II, III, and VI of the drawings, or in the eye 6 in the pro- 1.- As a new article of manufacture, an adj ustable stay for suspended sliding doors, conretain said arm in its required position, either In testimony whereof Ihave hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the I 5 county of Onondaga, in the State of New York, 1 this 6th day of June, 1884,

EMIL LAASS. [L. s]
