LOCK FOB SLIDING DOORS.

Specification o Letters Patent.

Patented June ,29, 1909.

Appcaton filed March 10, 1909. Serial No. 482,446.

To all who/m it 'may concern:

Be it known that l, Janus n.. BnNnnire'r, a citizen of the United States, and a resident ol" the city oi New York, borough ot' Manhattan, in the cour and State ot New York, have invented a new and improved Lock for Sliding Doors, of which the following is a lull, clear, and exact description.

My invention relates to locks ter sliding doors, my more particular purpose being to produce a lock requiring no key and easily manipulated by hand for the purpose ot sccuring the door.

More particularly stated, my invention comprehends a plate mounted upon a movable door and sunken thereinto, Ythe plate being provided with a recess of a general annular term, and a hinge member mounted upon some stationary part adjacent to the doorway and provided with a pivotally mounted bolt tor engaging the plate by entering the recess thereof, the arrangement ot the parts being such that the swinging plate may be swung back into a normal position of inactivity or may be temporarily secured relatively to the plate in the movable door member.

Reference is to be had to the accompanying drawings forming a part otl this spcci'lication, in which similar characters of reference indicate corresponding partsin all the Vfigures.

Figure 1 is a sectional perspective showing my improved lock in use upon a sliding door, Fig. 2 is a substantially central horizontal section through the parts shown in Fig. l Fig. 3 is a horizontal section similar to Fig. 2, but showing the door as moved back and the swinging bolt as occupying its normal position ot' inactivity; Fig. l is a front view of the metallic plate which is carried by the movable door member Fig. 5 is an edge view ot the same; and Fig. 6 is aplan view ot' the hinge member complete.

Boards 7, S are so arranged and supported as to form a door pocket therebetween, and movably mounted within this door-pocket is a door member Q. Carried by the door member 9 and sunken into the same is a metallic plate 10 provided with a recess 11 having the general form of a wedge, and being bounded by a shoulder 12, as will be understood from Fig. t. The edge of the plate 10 opposite the shoulder 12 registers flush with the adjacent surface of the door member t),

as may be seen at 13, Fig. o.

A latch 14 is, by aid ot a pivot 15, mounted upon the plate l() and may bc turned by hand. rlho plate 1() secured upon the door member 9 by aid ol' screws 16. Mounted upon a stationary post 17 is a plate 1S, this plato being secured to the post by aid ot screws 1.9. Journalcd upon the plate 18 is a swinging plate 21 which is provided with a knob 22, this knob being ole proper size to easily enter a hole 20 in the plate .18.

rlVhe operation of my device is as follows: When it is desired that the door member 9 may be moved freely in either direction, the swinging plate 21 is turned into the position indicated in Fig. 3, the knob 22 entering the hole 20. 'lhe swinging plate 2]. is now completely out ot the way so as not to interfere with the tree .movements ot the door member. It', however, it be desired to secure the door 9, the door is moved into suitable position, as indicated in Fig. 2, and the swinging plate 21 is moved angularly outward so that the end ol the plate engages the shoulder 12. Any movement oi the sliding door Q toward the right, causes the swinging plate 21 to act like a pawl that is to say, to bite against the shoulder 12 and ellectively prevent any travel ot the door member toward the right. The operator next turns the .latch 14 into such position that it hangs downwardly from the pivot .15, as indicated in Fig. 1. The swinging plate 21 can not now be moved away from the plate 10 until the operator again turns the latch 141; into its normal position which is indicated in Figs. i and 5.

Having thus described my invention, l claim as new and desire to secure by Letters Patent:

1. A device of the character' described, comprising a door member movable in thc general direction ol its width, a plate mounted upon said door member and provided with a recess having the general lorm ot a wedge and provided with a shoulder, and a plate journaled upon a stationary member disposed adjaccnt to the path ot travel ot said door member and adapted to swing, said plate being provided with a portion for entering said recess and engaging said shoulder.

2. A device of the character described, comprising a movable door member, a metallic member sunken thereinto and provided with a shoulder, a stationary member disposed adjacent to said movable door member, a plate secured to said stationary Cil Cir

lOl)

member7 and another plete pivoted upon said last-mentioned plate and adapted to engage seid shoulder of said metallic mem- 3. The combination of a movable member adapted to travel in a door pocket, e ste.- tionary member disposed adjacent to said door pocket, a plete mounted upon seid stationery member and provided with en opening, e swinging plete pivotallv mounted upon seid inst-mentioned plete and provided with e, knob for entering said opening when seid swinging ple-te is turned for this purpose, and e Closure member disposed partially Within said door pocket and adapted to travel Within the seme7 seid door pocket being pro-.

vided Witli a portion having a shoulder for engaging the outer end of said swinging plate.

Ll. The combination of a movable door, a

i stationery member disposed adjacent to seid. door, a plete pivotally mounted upon said stationary member and adapted to be swung toward and from said door, and a latch mounted upon said door and adapted to engage seid plete for the purpose of holding the same in engagement With seid door.

ln testimony whereof l have signed my neme to this speoiiioution in tlie presence ol two subscribing Witnesses.
