DOOR.

Specification of Letters Patent.

Patented Apr. 5, 1910.

Application filed January 9, 1909. Serial No. 471,432.

To all whom 'it may concern:

Be it known that I, JOHN H. VAN ZANDT, a citizen of the United States, residing at Fort Worth, Texas, have invented certain new and useful Improvements in Doors, of which thefollowing is a specification.

This invention relates to doors and more particularly to doors which rotate on a vertical axis, and the object is to provide double doors for a bath-room by which access may be had to the bath room from either one of two rooms.

As a matter of economy it is desirable that one bath room may serve two adjoining rooms.

The object of this invention is to provide doors which will permit entrance from either one of two adjoining rooms to the bath room but which will not permit entrance from one of the adjoining rooms to the other and further to provide means which will prevent a party in one of the adjacent rooms from entering the bath room while the part-y from the other adjoining room is already in the bath room.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application and specification.

Figure 1 is a plan view of the door with sections of the wall structure of the adjoining rooms and of the bath room. Fig. 2 is a vertical section of the doors and of the cooperating sealing walls or guards. Fig. 3 is a horizontal section of one of the unlocking devices in perspective. Fig. 4 is an enlarged horizontal section through the locking devices carried by the doors, showing the construction of the doors about the locks. Fig. 5 is a port-ion of one of the segments, the view being an exterior of that part of the segment which carries a releasing device 25. Fig. 6 is a broken vertical section of one of the locks which are carried by the guard wall 11, and showing a section of one of the segments taken on the line .frof Fig. 5. Fig. 7 is a vertical section of a lock which is carried by the guard wall 12 and showing the locking bolts engaging the beveled groove in the segment 2. Fig. S is a vertical section of the lock which is carried by the guard wall 13, and also showing a section of the segment 3 taken along the line w of Fig. 5, thesegment 3 being rotated far enough to be adjacent to the lock 27. Fig. 9 is a vertical section of an unlocking device 25 which is carried by the segment 3.

Similar characters of reference are used to indicate the same parts throughout the several views.

This invention includes an oscillating or rotating partition 1 which carries segments of cylinders 2 and 3 and this partition 1 is mounted on a vertical shaft 4. The shaft 4 is mounted in a frame 5 which has upper and lower arms 6 and 7, the shaft 4 being j ournaled in the upper and lower arms with ball bearings 8, the ball bearings 8 at the upper end of the shaft being included between the arm 6 and a nut 9 which is screwed on the upper end of the shaft 4. A jam nut 10 holds the nut 9 in place. Normally the partition 1 closes the passage from one guestl chamber to the other.

In operation the wall sections 11, 12, and 13, which are concentric with the segments 2 and 3, coperate with the segments 2 and 3 and the partition 1 to close the passage from one guest chamber to the other. Normally a guestin either chamber can enter the door passage. A guest walks into the door passage and unlocks the segment 3. He can then turn the partition so that the segnient 3 will close the passage behind him. Segment 2 will pass around far enough to open the passage into the bath room. If the guest comes from chamber A, the segment 3 will be locked to the guard 12 and the segment 2 will close the passage from chamber B. As the guest from chamber A passes out of the bath room, he must step within the circle of the door segments and unlock segment 3 from guard 12 and then rotate the segment 3 back to its normal position before he can pass back to his room. Means are provided for preventing the rotation of the partition 1 more than 180 degrees. An upstanding lug or stop 14 is rigidly mounted in the ioor and the partition carries depending lugs 15 and 16 which are adapted to engage the stop 14 so that the partition cannot be turned farther after one of these depending lugs strikes the stop 14.

Means are provided for locking the door in the several different positions. Locks 17 and 18 are mounted on the sealing wall or guard 11 and serve to lock the door or the segments 2 and 3 in their -normal positions.

CJI

The edges of the segment 3 opposite the locks 17 and 18 have slots 19 therein. The locks 17 and 13 have bolts 20 and 21 which are projected normally in the slots 19 by springs 23. Guards or stops 24 are attached to the segment 3 and form shoulders or locks Which prevent the guests in the adjoining rooms from turning the door to effect an entrance from one guest chamber to the other adjoining' guest chamber. A guest in chamber A has no Way of unlocking the lock 1T on the side of the chamber B and the guest in chamber B has no Way of unlocking the lock 1S on the side of the chamber A.

An unlocking device 25 is provided for each guest chamber and the unlocking devices carried by segment 3. Then the guest in chamber A steps into the passage Way and 'thrusts the bolt 21 out of the segment 3 With the unlocking device 25, he can turn the door in the direction to permit him to enter the bath room, but he cannot turn the door in the opposite direction on account of the bolt Q0 and the stop 24. The guest in chamber B can step in the passage Way and unlock or thrust the bolt 2O out of segment and turn the door in the direction for him to enter the bath room, but he cannot turn the door in the opposite direction on account of the bolt 21 and the stop 24. rThe bolt Q1 or the bolt 2O Will be pressed far enough outwardly by the unlocking devices Q5 to permit the stop or shoulder 24 to pass under the bolt when the door is to be used and it is apparent that either bolt will fall back into its normal position immediately When the segment 3 assumes its normal position. rllhe metal forming the shoulder or step 24 may extend entirely back of the segment 3 to form a track for the bolts so that these bolts Will not press against the surface of the segment The stops 24 may thus be one piece of metal. As the guest from chamber A turns the door to enter the bath room, the edge of segment 3 soon passes the guard 12 and is automatically engaged by a lock iti and the door is operated in the same manner by the guest in chamber B, the edge ot the segment 3 passing behind the guard 13. The unlocking devices 25 are again used for releasing the door from either the lock 2G or lock 27. The unlocking devices 25 are made double, or rather they are made so that two separate and distinct motions are necessary for exit and entrance purposes. rlhe particular construction is necessary to prevent designing parties from nullifying the etllect of the locking bolts in the exterior guards or sealing Walls.

A casing 2S is bolted to segment 3. A handle Q9 which is in the form of a double bellcrank lever is journaled in the casing 28 by means of a fulcrum bolt 30. This handle is provided with arms 31 and integral therewith. T he handle 2S) is used to depress two depressing levers 33 and 34 which are pivotally connected to the sides of the casing 2S. rllhe lever 33 is pivotally connected With a bolt The levers 33 are tor the purpose of operating the locking bolts 20 andZl7 there being a lever 33 for each unlocking device 25. The bolt 2O or the bolt 21 is operated simply by pulling the handle 29 in the proper direction which the guest does when he Wishes to operate the door. The lever 34 is pivotally connected to a bolt 3G. The bolt 36 is used for operating the lower one of each ot' the lockingl bolts hereinafter described which are located in the guard Walls 12 and 13. Springs 37 hold the levers 33 and 34 in their normal positions so that the bolts 35 stand at the entrance ot the holes through the segment 37 and as the locking bolt Q0 or 21 stands normally projected into the segment 3 from the guard 11, the bolt for unlocking either one ot the bolts Q0 and Q1 is ready to take etteet thereon as soon as the handle Q9 is moved.

The locks 27 and 26 are similar and only one will be described. Each lock has a casing 3S attached to the guard ' alls 12 and 13. TWO bolts 39 and 40 are mounted in the casing 38 and both bolts are projected inwardly by springs 41. There is no slot or hole in the segment 2 for either one of the bolts 39 or 40. The edges ot the segment 2 opposite the bolts and -l-O must be beveled as shown by dotted lines in Fig. 1 so that these bolts will ride up on the outside ot segment 2 as one of the edges ot segment 2 comes against these bolts. The edges of segment 2 must also be beveled at the same place so that the bolts Q0 and 21 Will ride up on the outside of segment The function of the bolt 39 is to prevent the rotation of the door When no person is in the passage way, consequently a person on the outside of the passage Way cannot rotate thedoor farther than to make the stop 24 come against the bolt 3S). But a person Within the passage Way can use the unlocking device 25 to shove the bolt 3.) out of the Way of lock 24 and thus pass on to the bath room. The function of the bolt 40 is to engage a slot 42 in the edge of the segment 3 to lock the door against movement While a person is in the bath room. The bolt 40 will ride up the bevel 43 on the edge of segment 3 and drop in the slot 42. The slot 42 is long enough for the segment 3 to rotate far enough to permit the party to enter the bath room. The guest from chamber B could enter the bath room. The guest in chamber A might turn the door slightly, but he could not turn the door tar enough even to see into the bath room because the bolt 40 would catch against the shoulder 44 or shoulder 45 at the ends of slot 42. lVhen @sages the party desires to leave the bath room, he can step within the door passage and by means of the unlocking device 25, with bolt 36, shove or thrust the bolt 40 out of slot 42. The function of bolt 36 can now be understood. The function of the double bell crank lever or handle 29 will now be understood. @ne motion of this handle operates bolt in entering the bath room and the other motion of this handle operates bolt 36 in leaving the bath room. The bolt 40 is provided with a handle 46 for use in case of accident. If a party should become helpless while in the bath room, a person in the chamber from which the party went could use the handle 46 to release the bolt 40 so that entrance could be had to the bath room. The bolts 35 engage springs 4S to thrust bolts 20 and 21 and 39 out of segment 3, and the bolts 36 engage springs 49 which operate in slot 42) to thrust bolts 40 out of the slots 19. Springs 48 and 49 are attached to the segment 3. The springs 48 operate in slots 19.

It may be desirable at times to make the bath room private to one of the two adjoining rooms. For this purpose a lug 47 is placed on the exterior surface of the segment 3. A lock 50 is mounted in the partition wall of the room on the side of chamber B whereby a key may be used to thrust a locking bolt 51 in the path of the lug 47 so A that a guest in chamber A cannot open a passage way to the bath room. In like manner a lock 53 may be mounted in the partition wall on the side of chamber A whereby a Akey may be used to thrust a locking bolt 54 in the path of lug 47 so that a guest in chamber B cannot open a passage way to the bath room. The lug 47 must be in a different horizontal plane from the locking mechanism previously described.
