LATCH.

SPECIFICATION forming part of Letters Patent N o. 685,969, dated November 5, 1901.

Application tiled May 22, 1901.

To @ZZ whom t may concern:

Be it known that I, WILSON D. CAMPBELL, a citizen of the United States, residing at Autreyville, in the county of Golquitt, State of Georgia, have invented certain new and useful Improvements in Lat-ches; and Ido hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rllhis invention relates to latches ingeneral, and more particularly to that class used upon sliding car-doors; and it has for its object to provide a construction which will-be easy and efficient in operation and wherein when the latch is in engaging position there will be two points of attachment to the door and two points of attachment to the side of the car.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is an elevation showing a portion of a car and its door equipped with the present invention, the latch being in engaging position. Fig. 2 is a view similar to Fig. l and showing the latch part way through the keeper and with the bolt raised by the tongue, the keeper being broken away. Fig. 3 is a section on line 3 3 of Fig. 1.

Referring now to the drawings, there is shown a car 5 having a door-opening in its side, as is usual in freight-cars, and to cover which door-opening there is arranged a laterally-slidable door 6, the end of which is adapted to lie against the jamb 7, with the outer faces of the door and jamb flush. On the jamb is fixed a keeper 8 in the form of a U- shaped plate having the ends of its legs bent outwardly to form attaching-feet, secured to the jamb in the usual manner, and through the legs of the keeper are formed verticallyalining perforations 9 and 10 for a purpose to be presently explained.

Upon the car-door 6 is pivoteda latch 11, at the outer end of which is formed a head 12, and the rear faces of the head, which project both above and below the latch, form the abrupt shoulders 13 and 14, of which the shoulder 13 is nearer to the free end of the latch than is the shoulder 14. When the door is moved into closed position, the lower beveled edge of the head strikes against the upper Serial No. 61.479. llo model.)

face of the lower leg of the keeper 8 and in sliding thereover is raised, and when the shoulder 14 has passed the keeper the latch drops, so that the shoulder 14 engages behind the keeper to hold the door against rearward sliding movement.

A guard 16 is disposed over the latch 11, and in the lower edge of the latch is a notch 17, which when the latch is in engaging position receives the adjacent face of the guard, so that if strain is put upon the door to open it a part of this strain will be upon the guard and it will not be entirely upon the pivot of the latch.

To hold the door from sliding open if the latch should be thrown upwardly from engagement with the keeper, a bolt 1S is provided, and consists of a plate having spaced longitudinal slots 19 and 20, through which are passed attaching-bolts 2l, engaged with the jamb of the car-door, so that the bolt may have vertical sliding movement. This bolt has its lower end beveled and lies normally in such position that when the car-door is slid shut the end of the latch strikes the lower beveled end of the bolt and forces it upwardly to permit the latch to pass through the keeper 8. When the latch has passed into position to engage the shoulder 14 with the keeper, the shoulder 13 has passed beyond the bolt, and the latter then drops into engagement with the shoulder 13 and holds the latch against withdrawal. If, then, the latch be jolted or otherwise thrown upwardly, the bolt moves with it, but remains in engagement with the shoulder 13. The bolt 18 also serves by its Weight to hold the latch down, and being mounted independently of the keeper it Amakes a most strong and durable construction. It will be seen that when the latch is `in its engaged position it has two points of strain tending to open the door is correspondingly distributed. It will be noted that the latch has a vertical perforation 20 therein for alinement with the perforations 9 and 10 to receive a seal-wire when the latch is in engaged position.

What is claimed is- The combination with a car having a door slidably mounted therein, of a keeper mount- IOC ed upon the car, a sliding bolt mounted upon the car independently of and beyond the keeper, a latch pivoted upon the door to pass through the keeper when the door is closed, said latch having a depending projection for engagement behind the keeper and having a notch in its upper `edge for engagement by the bolt, said latch having also a notch in its lower edge adjacent to its pivot, and a second keeper fastened to the door independently of the latch, said second keeper being disposed over the latch to engage in the last-named notch thereof when the depending projection of the latch is engaged behind the first-named keeper.

In testimony whereof I hereunto sign my name, in the presence of two subscribing Witnesses, on the lst day of April, 1901.

WILSON D. CAMPBELL. Vitnesses:

M. A. BETHUNE, D. A. AUTREY.
