Application filed November 2, 1993. Serial No. 672,382.

This invention relates to an improved guide for folding doors which is ca able of easy adjustment and which is esigned to i provide a bearing fbr a roller which travels in a grooved rail and which is held in depressions or inequalities of the rail by reason of a spring which presses down on the ball and its holder and holds the ball in contact at all times with the rail but which under normal travel orpressureis relieved or any support of the door byreason of a limited upward movement of the ball sup.-

ort.

p The invention is illustrated in the accompanying drawings in which Figure 1 is a face view partly broken away of the partition with the doors in extended position to close the opening. Figure 2 is a section taken on line 2-2 in Figure 1 and Figures 3, 4, 5, and 6 are sections taken on line 33 in Figure 1 with the doors in various positions. Figure 7 is an enlarged sectional view of the frame and the door. Figure 8 is a similar view taken at right angles to Figure 7. Figure 9 is a section taken on line 9-9 in Figure 7 and Figure 10 is a perspective View of a pintle situated on the door. Figure 11 is a detail section of a roller on the end of the pintle and Figures 12 and 13 are detail perspective and top view respectively, of a modified form of latch.

In the drawing, the door frame is shown equipped with three sets of doors and on one end of the frame is seated a strip 10 to which I prefer to secure one of the doors which consists of the members 12 and 13 which are hinged together as at 14 so that they can fold, the member 12 being hinged as at 15 to the strip 10 since this set of doors need not be slid longitudinally in the frame.

The other doors, however, need to he slid to one side and then folded and I show two of such sliding doors, each consisting of a member 16 and a member 17 hinged together at 18.

At the top, the door frame is provided with a slot or groove 19 and each of the doors members 16 has at the top and on the side toward which the doors are slid toward the closed position, a pintle 20, the pintle thus holding the door upright and usually fitting somewhat loosely in the slot so that a roller 21 on the top of the pintle, can roll easily being usually provided with ball bearings 22 as will be evident in Figure 11. Steadying posts 23 are arranged at the free ends of the doors and have rollers 24 similar to the rollers 21 of the pintle.

The doors are shown extended so as to close the opening in the frame in Figures 1, 2,. and 3 and when the opening is to be opened for substantially its full width, the doors 12 and 13 are folded as shown in Fig.- ure at and then the next door which consists of the members 16' and 17 slid along the door frame until it is adjacent to the folded .door and at this point, I dispose a latch which is shown in detail in Figure 9. The latch is placed on the bottom face of upper rail or the upper member 25 of the door frame and comprises a plate 26 fastened by screws 27 or otherwise, and a swinging latch 28 which is pivoted at 29 to the plate 26 and is held by a spring 30 so that it normally rests substantially parallel with the direction of sliding movement of the door in which position it is maintained by a suitable stop such as the pin 31 shown in F i ure 9.

6n the pintle 20, I place a lug 32 which projects from the pintle so that when the door is swung, it swings the latch 28 so that it takes a position across the slot as will be evident from Figures 5 and 6 where I show at a the latch in its locking position which prevents any sliding of the door while folded as the luv extends beyond the pivot 29 of the latch. 'Ihe third door can then be similarly folded as shown in Figure 6.

A modified form of latch is shown in Figures 12 and 13 in which the fixed plate 33 is substituted for the plate 26 and the projecting plate 34 is substituted for the lug 32 and when swung to the dotted position shown in Figure 13, resists any sliding movement of the door while the door is folded.

At the bottom of the doorway, I place a rail 35 which rail is trough-like and at the bottom of the door at each end thereof, as will be seen from Figure 1, I provide a socket 36 which as illustrated, consists of side plates 37, top plate 38 and a bushing 39. The sleeve 40 is screwed into the bushing and is held in adjusted position by a locking screw 41* accessible from the edge or face at the end of the door.

Slidably arranged in the sleeve 40, is a stem 41 with a shoulder 42 which shoulder abuts on the sleeve 40 to support it and has a recess 43 to receive a ball 44 which ball travels in the rail 35. A spring &5 abuts on the top plate 38 andon the top of the stem 41 and when any inequalities in .the rail are present, in view of settling ,or other reasons, the rail becomes depressed at points,

the spring 45 acts to push down on the stem so that the collar and the ball and the rail are always kept in contact.

The ball is placed so'that it is substan-;

tially central with the axis of the pintle 20 at thehingeda end of the door and in, line withthe axis of the supportin post at the other end of the door so thatt- 1e two mem- V berstcomprising the door. are maintained sleeve, the shoulder havin a shoulder to abut on the lower end of the sleeve, a spring abutting on the top plate and extending into the sleeve and held thereby in engagement with the top of the stem, a rail witha' groove therein, and a ball in the groove and seated in the shoulder of the stemf 2. A .,guide for foldin doors, said guide comprism a socket inc uding a top plate and a bus ing spaced apart, a sleeve open from end to end and screw threaded into the bushing, a stem extending part way up into the sleeve from the bottom and having a shoulder to engage the bottom of the a a roller on the bottom thereof, and a spring seated in the upper part of the hollow sleeve and abutting on the top; plate and end of the stem.

In testimony that I claim thetforegoing, i

I have hereto set my hand, this 1st day of November, 1923. 1 a a v a a a l' J. c. KOOP. p
