Sept. 13, 1938. ca. ZANINOVICH DOOR LOCKING BAR Filed Jan. 25, 1938 W/AcV/A WITNESSES W INVENTOR Gear-5e zaninovich/ ATTORNEYS Patented Sept. 13, 1938 UNITED states esrss'r @FFWE 3 Claims.
This invention relates to locking bars for doors and particularly to an improved construction for looking a sliding door, an object being to provide a simple construction which will clamp the door 5 against the building or its frame at both sides when the bar is fully functioning.
Another object of the invention is to provide a locking bar for sliding doors wherein the bar is pivotally mounted on the door and coacts with 10 interlocking members at each side.
A further object of the invention is to provide a locking bar for sliding doors which may be integral throughout or may be made in'two or more parts and adjustably connected together so 15 as to adapt the bar to doors of different sizes.
In the accompanying drawing Fig. l is a'side view of a bar in functioning position disclosing an embodiment of the invention;

Fig. 3 is an enlarged sectional View through Fig. 1 approximately on the line 33;
Fig. 4 is a perspective View of the locking bar shown in Fig. 1;
Fig. 5 is a view similar to Fig. 4 but showing a modified construction of bar;
Fig. 6 is a fragmentary sectional View through Fig. 5 approximately on the line 66.
30 Referring to the accompanying drawing by numerals, I indicates the side of a building, as for instance a barn, and 2 a door runway. A door 3 is slidingly mounted on the runway 2 so as at one time to cover the door opening and at 35 another time to expose the same.
Sliding doors similar to door 3 are old and well known and usually rather loosely contact the wall of building I. In the present invention there is provided a locking bar 5 which not only looks the 40 door 3 closed but causes the same to press against the building I as illustrated particularly in Fig. 3. The locking bar 5 is made from a piece of metal, as for instance steel, and is provided with a stiffening or reinforced rib 6 extending from one end to the other centrally except for the space I which is reserved for the head of a pivotal bolt 8 which extends through the aperture 9. Bolt 8, as shown in Fig. 2, extends through a sleeve I which is permanently fixed in the door 3 and 50 which is preferably made of metal. At one end the bar is formed with an apertured enlargement I I extending from one side of the bar. This enlargement is adapted to accommodate one leg of a U-shaped catch l2, which catch is preferably 55 slightly upset at I3 so that it cannot be removed from its position. The free leg I4 of catch I2 is adapted to be inserted into an eye I5 secured to the wall of building I in any desired manner, as for instance by having a bolt extension l6 extend therethrough and a suitable nut applied. 5 At the opposite end of the bar 5 there is provided a hinge knuckle ll which coacts with knuckles I8 on an L-shaped hasp I9. A suitable pintle 20 connects the knuckles together so that the hasp i9 may swing back and forth as desired. The 10 other end of the hasp is provided with a slot 2| which is adapted to readily slide over an eye 22 secured in place in any suitable manner to the wall I, as for instance similar to eye I3. The locking bow or shackle 23 of a padlock 24 is adapted to be inserted into the eye, as shown in Fig. 1, when the bar is in full functioning position. This prevents either end of the bar from becoming released and also acts with the catch I2 in holding the door 3 against the wall I.
When it is desired to open the door 3, lock 24 is removed and then the bar 5 is swung upwardly, for instance to the dotted position shown in Fig. 1. This upward movement will cause the leg I4 of catch I2 to move out of the eye I5. 25 The door 3 is then free to slide back and forth on the runway 2.
Instead of having the bar 5 made to fit only a certain size door, the same inventive concept could be arranged in a modified structure which would fit different size doors.
A modified form of the invention is shown in Fig. 5, in which it will be seen that the bar 5 is formed of a tubular part 25 and a rod part 26. These parts are each provided with apertures, namely, apertures 21 and 28. A bolt 8' is adapted to be inserted through any of these apertures after they have been properly aligned. It will be understood, however, that the sleeve 1 IE] is preferably central of the door whether the 4 door is large or small, and the adjustment of the parts 25 and 26 will take place before the bolt 8' is applied. Aside from these detail structures, the construction and arrangement of bar 5' is the same as bar 5 and the same reference numerals will be used.
1. A locking structure for a door comprising a bar adapted to extend from one side edge to the other side edge of the door, means for pivotally mounting the bar to the door, a catch structure arranged at each end of the bar body, a fixed eye interlocking with one of said catch structures, a second fixed eye interlocking with the second catch structure, and a padlock shackle extending through said second-mentioned fixed eye.
2. In a sliding door locking bar, a bar body having an aperture arranged centrally thereof, a tubular enlargement at one end, a substantially U-shaped catch having one leg rotatably mounted in said tubular enlargement, said bar body at the opposite end having a hinge knuckle, a latch formed with a pair of hinge knuckles coacting with the first-mentioned hinge knuckle, a pintle for pivotally connecting said knuckles together, said latch having an eye-receiving slot, a pivotal bolt extending through the central aperture of said bar body and the door on which the locking bar is mounted, means coacting with one leg of said U-shaped catch for holding said door in a given position, and auxiliary locking means ing position, a latch structure pivotally connected to the opposite end of said bar, a second eye member interlocking with said latch structure, and a padlock shackle for preventing disengagement of said second eye member from said latch structure.
