MOUNTING FOR SLIDING DOORS.

To all whom it may concern:

Be it known that I, ALBERT Vors'r, residing in the borough of Brooklyn, in the count-y of Kings, city and State of New York, a citizen of the United States, have invented new and useful Improvements in Mountings for Sliding Doors, of which the following is a specication.

This invention relates to the mounting of sliding doors, such as sliding doors for show cases and the like, and relates particularly to the carriage for carrying and separating the series of rollers upon which the doors are supported, and it is the object oit the invention to provide a mounting1 for a sliding door of this character which is simple and cheap in construction and eflicient in operation.

Further objects of the invention relate to the construction of the doors and runways in which the rollers engage.

In the drawings accompanying and forming a part of this specification, Figure 1 is a perspective view, partly in section, of a portion of a show case and a pair of sliding doors with my improvements applied thereto. Fig. 2 is a sectional end view illustrating one manner of constructing the runway and the supporting of the doors on the rollers. Fig. 3 is a similar view illustrating a modied form of runway. Fig. 4is a view similar to Fig. 2 illustrating a still further modification of runway. Fig. 5 is a side elevation, partly in section, of the rollers and carriage, illustrating wipers at the ends thereof to clear the runway of any obstruction. Fig. 6 is a view similar to Fig. 5 but illustrating the carriage as consisting of sections and the manner of releasably connecting them together. Fig. 7 is a detail to illustrate the manner of coupling the two sections shown in Fig. 6. Fig. 8 is a side elevation of a modiiied form of carriage. Fig. 9 is a sectional end view of the carriage and rollers shown in Fig. 8. Fig. 10 is a detail end perspective of the carriage shown in Fig. 8 and illustrating means to prevent the accidental uncoupling of the sections. Fig. 11 is a detail in side elevation of the carriage shown in Fig. 8 and illustrating a modified form of wiper connected thereto. Fig. 12 is a sectional detail in perspective of a portion of the runway illustrated in Figs. 1 and 2; and Fig. 13 is a sectional detail in perspective of a portion Specification of Letters Patent.

of the binding member of the door shown in Figs. 1 and 2.

Similar characters of reference designate like parts throughout the different views of the drawings.

In the drawings I have illustrated my invention in connection with the mounting of sliding doors of show cases, and have shown only so much of a show case 14 as is essential to an understanding of the invention.

In Figs. 1 and 2 the show case is provided with a pair of runways consisting of juxtaposed metal strips of channel section 15, l15 in which engage a pair of sliding doors 16, 16, one for each runway, which are slidable relatively to each other in the usual manner. rIhe doors in said figures consist of glass having a metal binder 17. The doors are supported in the runways upon rollers 18, which are carried and separated by a carriage 19, which in Figs. 1 to 6 consists of a` metal strip channel shaped in cross section with the open side toward the bottom of the runway, the said carriage being of less height than the diameter of the rollers and provided with cut-out portions 2O through which the rollers project. At each end the carriage is provided with a pivoted wiper 21 normally resting upon the bottom of the runway to remove any obstruction which may be in the path of the rollers.

If desired the carriage may be T-shaped in cross section, as shown in Figs. 8 to 11, and may be constructed by securing two pieces of angle iron together as shown in Fig. 10 with portions cut out, as at 20', through which the rollers may project, or bent up of one piece as shown in Fig. 9. In this latter construction the rollers are preferably in pairs one at each side of the carriage. The carriage is preferably made up of sections to be connected or coupled up in any length required, and when constructed as shown in Figs. 1 to 6 each section is provided with a hook-shaped member 22 at one end and a laterally projecting pin 23 at the other end to be engaged by the hook, the sections being coupled together as shown in Fig. 7. l

When the carriage is constructed as shown in Figs. 8 to 11 each section is provided at each end with a hook shaped portion 24, the hooks being reverse to each other. In this latter construction to prevent the accidental uncoupling of the sec- CIV tions I provide a clip 25 substantially of U- shape to engage over the coupled hook portions.

In Fig. 3 the runways 15 are constructed by providing an intermediate wood section 26, in which case it would not be necessary to have the metal pieces of channel section, as in Figs. 1 and 2; in this instance the doors are shown as consisting of wood or wooden frames for apiece of glass. In Fig. 4 the runway is formed p by providing a channel shaped groove in the base of the case and also in the bottom oit' the door.

Variations may be resorted to within the scope of the invention.

Having thus\described my invention, I claim:

l. In a mounting for sliding doors, the combination with a runwayand a door slidably engaging therein, of a series of rollers engaging in the runway and upon which the door is supported, and a carriage to carry said rollers, said carriage comprising releasably connected sections.

2. In a mounting for sliding doors, the combination with a runway and a door slidably engaging therein, of a series of rollers engaging in the runway and upon which the door is supported; a carriage to carry said rollers, said carriage having no engagement with the runway or door; and wipers pivotally carried at the ends of the carriage to engage with the bottom of the runway to clean the runway of any obstruction as the lrollers move to and fro.

3. In a mounting for sliding doors, the combination with a runway and a door slidably engaging therein, of rollers engaging in the runway and upon which the door is supported, and a carriage to carry and separate the rollers, said carriage comprising sections having hook-shaped portions at the ends, said hook-shaped portion at one end of a section being reverse to that of its companion section whereby to releasably couple the sections together.

4. In a mounting for sliding doors, the combination with a runway and a door slidably engaging therein, of rollers engaging in the runway and upon which the door is supported, and a carriage to carry and separate the rollers, said carriage comprising sections having hook-shaped portions at the ends whereby they are releasably connected together, and a clip to engage over the connection of the sections to prevent accidental separating thereof.
