This invention relates to improvements in overhead door construction in which a series of doors arev separated by removable posts whereby, Whenthe doors are open, the vposts can' be removed to one side or the other, clearing the entire door space..

The objects of the invention are:

First, to provide such a structure with eiective removable door posts. A

Second, to provide improved locking means for retaining said door posts in place.

Third, to provide improved locking means to prevent4 the closing of the doors when the posts are removed.,

l5 Fourth, to provide improved transverse track and transporting means for transporting such posts to the side of the door. Objects pertaining to details and economies of construction and operation will ap- *0 pear from the\description to follow. A preferred embodiment of my invention is ilustrated in the accompanying, drawings, in which:

Fig: 1 is a front elevation view of aibuilding having/a broad door opening extending substantially the width of the bullding wlth a series of posts dividing the same into doorways for the operation of single door sections or single vseparate doors. v

Fig. Gis an enlarged detail perspective view of the stop and lock latch for the upper end of one of the posts.

The parts will` be identified by their numerals of reference which are the same in all the'views. e

1, 1 are the side frames or door jambe of the broad door opening. 2 is the top frame of the entire doorway. 3, 3, 3 are the removoverhead doors 4', suc as those illustrated at the left of Fig.'1, one door being entirely closed and the other partially open, the doors to the right being. entirely open. The doors '4 are flexible doors made up of a series lof horizontal panels hinged together so that they can travel in the vertical track 5, thence into the curved portion of track 6, and then into the horizontal portion 7 above, the parts being indicated particularly in Fig. 4.

A guide roller 41 is secured to each door panel section and projects to travel in the said tracks in the well-known manner of the door known as the overhead door., Each ldoor post` is made up of a pair of uprightf angle bars 31. These are held in spaced re'-` lation at' the top by plate 8 which projects inwardly from the posts into the building. A yfront plate 9 is secured to'the lforward edge of the plate 8 by a pair of angle brackets 91. The plate 9 is adjustable thereon by bolts 92 in the slots 93, see particularly Fig. 3. j A pair of outwardly projecting rollers 10 are carried on journal pins 101 fon plate ,9 and are disposed in the inclined cross track `11 which is carried on fixedparts above to be later described. This track is a very little j higher at the end toward which the4 disconnected posts are moved so that in movingithe' posts'they will clear the floor.

Fixed post members 12 corresponding to 90."

. inches for the width of an the angle bars 31, 31 are secured to the wall and are provided with supporting plate 1.3, corresponding to the plate 8 below. To this plate 13 are secured the curved portions of track 6, in the same relations as the vertical tracks 5 below, the lower ends thereof registering with the tracks 5 on the posts when the posts are in operative position. Transverse track 11 is secured to the plates 13 by angle brackets 131 in the inclined relation previously referred to. The incline is about two eight foot door. It will thus be seen that when the posts are released they can be removed along the track to the side of the doorway within the return wall and as many posts accommodated as space permits or as the door opening requires. I

The upper end of each post is provided with a stop plate 14, see Figs. 43 and 6, secured to the plate 8 and adapted to contact with one side of the lower edge of upper plate post in working position. On the opposite side of plate 8 is disposed latch bolt 15, suitably supported. to move into position and retain the post definitely in place. A vertically operating lock bolt 16 is guided between the lower ends of the angle plates 31 constituting the' post. Underneath the post is a floor plate 17 with a central slot or socket 172 to receive the lower end of thebolt 16. This floor plate 17 is provided with a stop rib 171 to receive and guide the `lower end of the post. The bolt 16 is provided with a perforated ear 1.61, and the lower end of bolt 15 is provided with an eye 151. A cir' cular pivoted actuating plate18 with handle 181 is pivotedat 182 on the inner side of each post. Links 162 extend upwardly from the bolts 16 to one side of this operating plate 18. Links 152 extend down from the eye,151 on the bolt 15 to the opposite side of the disk 18. It will thus be seen thatwhen the disk is moved to the position seen, at the left of Fig. 2, where the post has been released, both of these latch bolts have been withdrawn so that the post can be moved freely along the track When the post is in position, as seen at the right hand of Fig. 2, the lever is moved to a position at right angles to that appearing at the left and the bolts'a-re forced into engagement and retain the posts effectively in place. The action of these bolts could ofcourse be accentuated by springs but it is not necessary. The actuating means is like that often used for door bolts.

iBecause of the incline of the track 11 as above pointed out, the lower ends of the posts clear the floor until they'y are moved to their articular location. Because of this fact, t e lower ends of the postsv can swingy laterally of the supporting track 11 and into the room or building closed by the door, pivoting on their supporting wheels 10 in their 13 to secure the alignment of the door tracks 11, as seen in cross section in Fig. 4, and thus permitting the clearance of the upper ends of the plates 14 until the posts slide down to their'particular positions, when the upper end of plate 14 will engage the corre-` sponding plate 13 and the latch 15` may be permitted to engage.

This clearance can, of course, be accomplished by making the edges of the plates 13 successively ofslightly different` relative height, but the extent of the engagement is so small that this provision is not a necessity, the swinging of the lower ends of the posts being suiicient.

It will be very clear that when the doors are open under these circumstances and the posts removed, it would be a very serious matter if anyone should close one of the doors. It would drop down out of the ,curved tracks 6 and it might not be very readily replaced. At any rate the swinging door would be highly undesirable. I therefore provide automatic means for locking and retaining each open door in elevated position when the post is removed. s

To accomplish this I provide a pair of pivoted lock latches.19 supported' on rockshaft 191, each with a hookedv engagingv end 192 adapted to project through apertures 61 in the track 6. I connect spring 20 to the lower end of this latch and the opposite end of the spring to an eye 201 on the bracket 131. This tends to hold the latches always in engagement. The lower end of the left hand latch 19` I oii'set at 193, providing the same with a beveled cam surface disposed to be contacted with the outer edge of the vstop plate 14 on the removable post, so post is forced into position the edge of stop plate 14slides along the bevel 193 and cams and forces the lower end of the latch outwardly, withdrawing the engaging locking portion 192 from the track 6.

Thus it will be seen that automatically, when the door post is removed, land it can only be removed when the door is open, the lock latch 19 swings to position and locks the door in open position. This structure can be varied greatly in detail. The transverse track can be used with any sort of attaching and supporting means for the post, although it has special advantages in track might be dispensed with, and. as the posts are not unduly heavy they might be carried by an attendant and inserted in place. This, however, would be a matter of very considerable inconvenience.

The lever means for operating the bolts at top and bottom simultaneously mightbe'dispensed with but it is very convenient and automatically holds .the bolts in withdrawn position ready to be inserted when the post is set into place. All of this is of advantage.

Separate and distinct locks might be prethat when the lll the arrangement here shown. The

pared for locking the doors open, but it is far better to have this done automatically.
