Specification of Letters Patent.

Patented April 9, 1907.

Application filed November 7,1906. Serial No. 342,414.

To all whom it may concern:

Be it known that I, DAVID L. MINIER, a citizen of the United States, residing at Ithaca, in the county of Tompkins and State of New York, have invented a new and useful Railway-Car, of which the following is a specification.

It is the usual custom to lock the doors of toilet-rooms when the trains approach stations and to unlock them after leaving the same; but this is often overlooked by the One of the principal objects is to provide automatic means of a simple, novel, and practical nature that will lock said doors While the ears are at a standstill and will automatically maintain the same unlocked While the invention is particularly applicable to railway-ears, it will be evident that it may be employed wherever found convenient or desirable on vehicles of other types.

The preferred embodiment of the inven tion is illustrated in the accompanying drawings, wherein- Figure 1 is a section through a portion of a car, showing a door and the novel locking means applied. thereto. Fig. 2 is a sectional view at right angles to Fig. 1. Fig. 3 is a view similar to Fig. 1, but showing the door unlocked. Fig. 4 is a detail perspective view of portions of the mechanism with the parts partially disassociated.

Similar reference-numerals designate corresponding parts in al the figures of the drawings.

In the portion of the car disclosed a wall 5 is provided with a doorway surrounded by a I easing 6 and closed by a door 7. The floor of the ear is shown at 8. The lock for the door consists of a reciprocatory bolt 9, slidably mounted in the casing, its inner end being received in a socket element 10, located in the edge of the door. The lock is preferably urged to closed position by a spring 11, the lower end of which is bifurcated, as shown at 12, and straddles the bolt, bearing against a pin 13 passing through said bolt. The bolt may be moved to an inoperative position by a key, as 14, the keyhole 15 being placed in the door-casing 6.

The outer end of the bolt 9 is pivoted, as shown at 16, to one arm 17 of a bell-crank le- 1 ver 18, the other arm 19 of said lever being i connected to the upper end of an upright reeiproeatory link 20, said link passing through the floor 8 and preferably guided ina plate 21, secured tosaid floor. The lower end of this link is in the form of an enlarged head 22, that is arranged between a pair of brackets 28, secured to the under side of the floor and hav ing their lower ends connected by a pivot or pintle 25. An upright slot 26, formed in the head, receives this pivot or pintle and per niits the vertical movement of the link, as will be evident.

A swinging vane 27 is carried by the pivot or pintle 25 and is disposed transversely of the car, said vane normally assuming a vertical position and having oppositely-extending curved fingers 28 at its upper end on opposite sides of the pivot or pintle, which fingers are disposed over a pair of rollers 29, carried by the adjacent portion of the head 22 of the link 20.

The operation of the structure may be briefly outlined, as follows: As long as the ear or vehicle is at a standstill it will be evident that the vane 27 will hang in a perpendicular plane and that the bolt 9 will be engaged with the door, so that said door will be locked against opening. If, however, the car is moved in either direction, the resistance of the air will efl'ect the swinging movement of the vane to a trailing position. Consequently the forward finger 28 will bear down upon the roller 29, disposed beneath it, thus moving the link downwardly, swinging the bell-crank lever, and sliding the bolt 9 to an inoperative position. It will thus be evident that as long as the vehicle or car is in motion the door will be unlocked, and, furthermore, it will be clear that when the eareomes to a standstill the parts will reassume their former position, or, in other words, the door 7 will be locked. Novel means of a simple nature aretlms provided for locking and unlocking the door during the stoppage and movement of the train, respectively, and, moreover, these movements are obtained without regard to the direction of movement of the ear.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-deseribed invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, prodescribed my invention, desire to secure by having one arm connected to the bolt, a

swinging vane, and a reciprocatory link operated by the swinging vane and having a pivotal connection with the other arm of the bell-crank lever.

2. The combination with a vehicle, of a door mounted on the vehicle, a reciprocatory bolt for locking the door, a swinging vane, and connections between the bolt and vane for effecting the reciprocation of the bolt on the swinging of the vane.

3. The combination with a vehicle, of a door mounted on the vehicle, a lock for the door, a pivot-support, a link having connections with the lock and having a slot that receives the pivot, and a swinging vane mounted on the pivot and having an engagement with the link.

4. The combination with a vehicle, of a door mounted on the vehicle, a lock for the door, a bracket having a pivot, a link having connections with the lock and having slots that receive the pivot, a swinging vane mounted on the pivot, and a crank-arm carried by the vane and having a movable engagement with the link.

5. The combination with a vehicle, of a door mounted on the vehicle, a lock for the door, an oppositely-movable vane, a single link having connections with the lock, and means operated by the vane to move the link in the same direction upon the movement of the vane in either direction.

6. The combination with a vehicle, of a door mounted on the vehicle, a lock for the door, an oppositely-movable vane, a single reciprocatory link having connections with the lock, and means operated by the vane to move the link in the same direction upon the movement of the vane in either direction.

7. The combination with a vehicle, of a door mounted on the vehicle, a lock for the door, an oppositely-movable vane, a single link connected to the lock, and devices rigidly carried by the vane and engaging the link.

8. The combination with a vehicle, of a door mounted on the vehicle, a lock for the door, an oppositely-swinging vane, a single link connected to the lock, and arms mounted on the vane and engaging the link on opposite sides of its pivot for effecting the movement of the said link in the same direction on the opposite swinging movements of the vane.
