WILLIlkM P. LAWSON, OF FOUNTAIN CITY, TENNESSEE.

FASTENER FOR SLIDING DOORS.

Application filed April 3,

To all whom it may concern:

Be it known that I, WILLIAM P. LAwsoN, citizen of the United States, residing at Fountain City, in the county of Knox and State of Tennessee, have invented new and useful Improvements in Fasteners for Sliding Doors, of which the following is a specification.

The object of the invention is o provide a new and improved form of fastener for sliding doors which constitute independently movable sections, one of which slides in front of the other. The device comprises a hasp which when not in use lies flushed with one section so that that section may slide past the other section, the said hasp being extensive when in use so as to engage an appropriate cooperating member carried by the adjacent section.

A further object of the invention is to provide a piece of hardware of the character mentioned which is simple in operation, durable and effective in operation and inexpensive to manufacture.

Other and further objects appear in the following description wherein the invention is set forth in detail:

As shown and described a specific embodiment of the'invention is adhered to, but to this embodiment the right is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest in so far as such changes or alterations are compatible in spirit with the annexed claim.

In the accompanying drawings:

Figure 1 1s a view in perspective showing the practical application of the invention.

Fig. 2 is a view partly in elevation and partly in section showing the manner of attaching the improved hasp to one of the sections of a sliding door comprising a plural number of independently movable sections. Fig. 3 is an elevational view looking at right angles to that shown in Fig. 2.

Fig. 4 is a section on the line 44 of Fig. 2. Referring to the drawings, there are shown portions of a sliding door consisting of independently movable sections, such as mentioned above. In buildings having door openings almost the width of the building and where it is impossible to provide a continuous door which when in open position would completely free the door opening, it is customary to provide a door consisting of independently movable sections, each one Specification of Letters Patent.

provided with its own hinges and movable in its own track. Such doors have one section sliding behind the other and sections 1 and 2 illustrated are parts of a door of this character. The improved hinge is provided for locking the one section to the other when the door is in closed position, and to this end there is attached on one edge of the section 2 an L-shaped plate 3 one leg of which is provided with screw holes to permit the use of screws 4 in attaching the plate to the edge of the door. The plate being L-shaped, the other leg extends at right angles from the leg which is attached to the section 2 and thls leg is provided with a depending staple 5.

The section-1 is recessed on that face adjacent the section 2, as indicated at 6, this recess being formed near that edge of the section 1 which stands near that edge of the section on which the plate 3 is attached when the door is in closed position. The improved hasp is attached to the section 1 1n the recess or pocket 6 and this hasp comprises a plate 7 formed with screw holes to permit the use of the screws 8 in attaching the plate to the section 1. Pivotally attached to the plate 7 at its upper edge there is a second plate 9 and this plate may swing down against the plate 7 when it will hang within the plane of the adjacent face of the section 1. Also it may be swung outwardly to assume a position at right angles to the plate 7 and in such a position it is designed to engage the staple 5, being provided with a slot 10 through which the staple passes. hen the plate 9 is engaged with the staple 5, as above described, a lock may be attached to the staple and the plate 9 will thus be secured to the staple and the sections 1 and 2 will be secured against relative movement. lVhen it is desired to open the door the lock 5 may beremoved. when theplate 9 will drop down against the plate 7, thus permitting the section 1 to be moved independently of the section 2, as plainly apparent from a consideration of the drawings illustrating the invention.

The invention having been described, what is claimed as new and useful is:

The combination with a sliding door post of a plurality of independently movable sections which slide one behind the other, of an L-shaped plate attached to one edge of one section and having a projecting leg at right angles thereto,the saidprojecting leg being provided With a depending staple, the other section being formed on the face adjacent the first 'section with a recess or pocket, a plate secured to said o ther section in the pocket, and a second plate hingedly attached to the first plate at the upper edge of the latter so that it may be swung down against the same by gravity and hang Within the pocket to permit the relative movement when the said second plate is raised and the door sections in proper relation for said engagement between the plate and staple.

In testimony whereof I afliX my signature.

WILLIAM P. LAWSON.
