JOHN OESTREICH, OF NORTH PLATTE, NEBRASKA.

AUTOMATIC LOCK.

Application filed May 19, 1915.

To all whom it may; concern Be it known that I, dorm OESTREICH, a citizen of the United States, residing at North Platte, in the county of Lincoln and State of Nebraska, have invented certain new and useful Improvements in Automatic Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will. enable others skilled in the art to which it app'ertains to make and use the same.

This invention is an improved automatic lock especially adapted for use for locking the door of a freight car but also adapted for other analogous uses, the object of the invention being to provide an improved lock which when a door is moved into contact therewith will automatically engage and hold the door, and prevent it from being casually opened, a further object of the in vention being to provide a lock of this character which may be used for securing a door either in a closed or in an opened position, so that when two of the locks are arranged for use in connection with a door, the latter may be secured in either of its two positions.

The invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings ;Figure 1 is a side elevation of a portionof a freight car wall provided with a pivotally swung door and with two of my improved locks, one adapted for securing the door in closed position, and the other for securing the door in opened position, the door being shown in the last named. position. Fig. 2 is a similar view, showing the door in closed and locked position.

one of the locks, showing the same in looking position. Fig. i is a similar view of the same at right angles to Fig. 3 and partly in section.

For the purposes of this specification a wall of a freight car is indicated at 1, the door opening at 2 and the door at 3. The door is pivotally connected to the wall at the upper right hand corner of the door so that the door may be moved angularly in a vertical plane, turned to the left to a vertical position to close the door opening and may be turned or swung to the right, and to a horizontal position, to uncover the door I opening and lie against the wall as indi- Specifieation of Letters Patent.

Fig. 3 is a detail elevation on a. larger scale than that of Figs. 1 and 2, of

cated in Fig. 1. To efiect this pivotal hanging of the door I provide the door with a hanger 4. A pivotal bolt 9 is attached to andextends through and projects to the other side of the car wall 1 and passes through the eye 7 and coacts with the hanger topivotally mount the door. The head of the bolt is connected at 9, the nut at 10 and washers 11, 12 are respectively on the inner and outer sides of the walls. On the left hand side'of the door opening is a stop 13 and at a suitable distance from the right hand side of the said opening and in a somewhat more elevated position than the stop 13 is a stop 14. The door is provided with a handle 15 near its lower left hand corner, and which operates as hereinafter described.

A lock 17 is arranged for securing the door in open position and a similarly constructed but a reversely arranged lock 18 is provided for securing the door in closed position. Each lock comprises a swinging locking bolt19 a gravity acting latch 20 and a lever 21 for releasing therlatch and also for coaction. with a sealing hook 22 to lock the latch and cause the latter to hold the locking bolt in locking position. The locking bolt comprises an arm 23, an arm 24 at the lower end of and at right angles to the arm 23 and a shoulder 25 on the opposite side from the arm 2i and at the lower end of the arm 23. The latch 20 is a bar which is pivotally mounted at a point intermediate its ends as at 26 and the upper movement, of which is limited by a stop 27, said latch, when lowered, engaging the outer side of the arm 23 and bar on the shoulder 25.

The lever 21 has a slot 27 extending longitudinally thereof and is pivotally mounted by a pivot pin or bolt 28 which also forms the pivot for the locking bolt 19 and passes through an opening near the up per end of the arm 23 of said locking bolt. The lever is hence arranged on the outer side of the locking bolt and for sliding as well as for pivotal movement on the pivot 28 and one end of said lever is pivotally connected to the latch 20 as at 29. The pivot which connects the lever and latch of the lock 18 is provided at its outer end with an eye 30. The said look also has a sealing hook 22 which is pivoted at 28 and the bill 31 of which is adapted to be passed through the eye when the bolt 19 of said lock is held in looking position by the latch 20, ,to'secure said bolt and latch in locked position, the said hook bill having an opening through a sealing Wire 32 may be passed as shown in Figs. 2 and 4E.

The levers are employed for raising the latches to cause the latter to release the looking bolts. Assuming-that this has been done the locking bolts assume an inclined position by gravity and are arranged at the limits of movement of the door. moved toopen position by swinging-it upwardly and in one directionas indicated in Fig. 1 it engages the upper portion of the locking bolt 19 of the lock 17 and turns said bolt to a vertical position so that the shoulder 2% thereofengages under the door and at 7 this instant the latch of said bolt drops on the shoulder 25' at the outer side of the locking bolt thus holding the, locking bolt in this position as indicated. When the door is moved to closed position, after having been released by the lock 17 its left hand edge engages the upper end of the locking bolt 19 of the lock 18 and turns said bolt to vertical position so that its arm 23- engages under the door, the said bolt is then engaged by this latch and if it be desired to seal the door in closed position the bill of the sealing hook 22 is passed through the eye 30 and a sealing Wire and seal applied as hereinbefore stated. 7 p

The handle 15 not only serves as a handle to enable the door to be moved but also operates the latch 20 through the lever 21 when the-door is opened or closed, the said handle throwing the lever 21 up and outward far enough to permit the latch 20 to fall in locking position.

Having" thus described my invention I claim '1. In combination with a door mounted for pivotal movement in a vertical plane a lock comprising a pivotally mounted look ing bolt to engage one corner of the door, a gravity acting latch to hold said locking When the door isbolt in engaged position, and apivotally and slidably mounted lever to release the latch.

2. In combination with a door mounted for pivotal movement in a vertical plane a lock comprising a pivotally mounted locking bolt to engage one corner of the door, a gravity acting latch to hold said locking bolt in engaged position, and a pivotally and slidably mounted lever to release the latch, the pivot of the locking bolt also forming the pivot for the lever and said movement on said pivot, a sealing hook also mounted on said pivot, and having a bill at its free end, the pivot which connects the lever With the latch having an eye for engagement by the bill of the sealing hook.

a In combination with a door pivotally mounted at one upper corner for vertical angular movement, and reversely arranged locks one for securing the door in closed and the other for securing the door in opened position, each of said locks comprising a pivotally mounted bolt to engage under one corner of the door, a latch to hold the bolt in engaged or locking position, and'a lever pivotally and slidably mounted and also pivotally connected to the latch.

In testimony whereof I aiiix my signature in presence of two itnesses.
