GUIDING AND SUPPORTING DEVICE FOR DOORS.

SPECIFICATION forming part of Letters Patent No. 296,629, dated April 8, 1884;.

I Application filed February 6, 1884. (N0 model.)

To ctZZ whom it may concern:

Be it known that we, Auos SANDERS and Boone S. Hnnnnnson, citizens of the United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in Guiding and Supporting Devices for Doors, &C., of which the following is a specification.

The object of vour invention is to provide a cheap, simple, and effective substitute for the usual combination of pivoted arms and levers for guiding and supporting doors, windows, &c.; and this object we attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a side View of a door with our improved device for guiding and supporting the same, the frame of the doorway and one of the studs of the wall or partition also being shown. Fig. 2 is a sectional plan on the line 1 2, Fig. 1; Figs. 3 and 4, sectional views of the guides for the top and bottom of the door, respectively; Figs. 5, 6, 7, and S, detached views of diiferent parts of the device, and Fig. 9 a view showing a modification.

Referring to Figs. 1 and 2, A represents the door, B one of the posts of the doorway, D D the opposite posts between which the door slides, E one of the studs of the wall or partion, F F the covering of said wall, G the ceiling, and H the floor, all of these parts being constructed in the usual and well-known manner. A slotted bar, J, is secured at the front end to one of the posts D, the inner end of said bar having an adjustable plate, a, the projecting end of which is pointed, so as to penetrate the stud E and support the inner end of the bar J, the plate, before the bar is fitted to its place, being adjusted on said bar to such a position as may he demanded by the distance of the stud from the posts D, and then secured in this position.

To the inner portion of the door A are secured two brackets or hangers, I), each carrying a pulley, d, and to a plate, f, secured to one of the posts D, is attached one end of a rope, 9, preferably a wire rope.

Hereafter, in alluding to this element of the combination, we shall call it a rope; but it should be understood that we are not limited to the use of a rope, as a chain, a leather strip, a flexible band of metal, or other equivalents of the rope may be adopted, and are included in our invention. 3

The rope 9 passes from the plate f under and around the rear of the lower pulley d, thence in front of and or er the upper pulley d, thence around a bearing on the plate a, or it may be through an eye thereon,) and thence to a slide, it, to which it is secured. This slide is guided on the bar J, and is adjustable thereon, so as to take up any slack in the rope, the adjustment being effe cbed by means of a screwrod, 45, which is confined longitudinally to bearings m m on the bar, and is adapted to a nut, it, on the slide 72', the front end of the rod being constructed for the reception of a suitable tool, whereby it can be turned to cause the adj ustment of the slide. (See Fig. 6.)

By passing the rope around the bearing on the plate a, and thence to a slide which draws forward in order to take up the slack of the rope, an extended movement of said slide is permitted; but this construction is not absolutely essential to the carrying out of our in-" vention. For instance, in Fig. 9 we have shown a plan in which the plate a is discarded, the inner end of the bar J being sharpened and projected into the stud E, and the rope 9 extending directly to the slide 71 which is moved inward in order to take up the slack; or this feature of our invention may be further modified by permanently connecting the upper and inner end of the rope g to the stud E and taking up the slack at the lower and outer end, where the rope is adapted to a socket, f, on the plate f, and is held therein by means of a wedge, f. (See Fig. 7.)

Secured to the rear edge of the door at the bottom is a bracket, 10, carrying a roller, 8, which runs upon a track, 8, upon the door and supports the rear portion of the door, the

balancing of the door being effected by the strain of the rope 9 upon the upper pulley d, which resists any tendency of the door to tip forward, and insures the traveling of the door in a plane parallel with the rail 8.

Lateral guidance of the upper portion of the door is effected by dowels t, projecting from the upper edge of the door and into a groove in a guide-strip, t, and lateral guidance of the lower portion of the door is effected by a roller, 2:, adapted to a groove in the lower IOO edge of the door, and carried by a pin on a plate, 12, secured to the floor between the posts D D.

When it is desired to remove the door, it is necessary to drop the same to such an extent that the dowels twill be free from the groove in the guiding-strip t,- hence we make the bracket 19 of the roller 8 vertically adjustable, the bracket-plate 19 being secured to a plate, 19 on the door by bolts p and being slotted, so that it is free to move vertically when the bolts are loosened, the adjacent faces of the plates being serrated or roughened, so as to prevent accidental shifting of the plate 10 when the door is in use. (See Fig. 8.)

If desired, the bar J may be utilized as a guiding-track for the door, a roller on the doorbeing adapted to said bar, and in the case of heavy doors a bar on each side of the door may be used, there being in this case two ropes g and two sets of pulleys d.

The brackets b are preferably constructed as shown in Fig. 1, so as to form hoods or shields for the pulleys d, and prevent the rope from leaving the same.

We claim as our invention-- 1. The combination of a door, A, with a rope, g, secured at its opposite ends, and passing over pulleys d at the rear of the door, as set forth. 7

2. The combination of the door and its pulleys with the rope g, secured at one of its ends to an adjustable fastening, as set forth.

3. The combination of the door and its pulleys, the rope g, the-fastening for one end of the same, and a bar, J, having an adjustable slide, h, for the opposite end of the rope, as set forth.

4. The combination of the door and its pulleys, the rope g, the bar J, having an adjustable slide, h, and the adjustable plate a, as set forth.

5. The combination of the door and its pulleys, rope g, the bar J, having a bearing for said rope, and an adjustable slide, h, as set forth.

6. The combination of the door and its pulleys, the rope g, the bar J, the screw-rod z, longitudinally confined thereto, and the slide -h, having a nut, n, adapted to said screw-rod,

as set forth.

7. The combination of the door A and its pulleys, the rope g, and a guide-wheel and rail for supporting the rear of the door, as set forth.

8. The combination of the door A and its pulleys, the rope g, the guide-rail s, and the Wheel 8, carried by an adjustable bracket, 1), as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
