LOCKING ATTACHMENT FOE DOORS.
Application filed April 25, 1322. Serial No. 556,468.
T 0 (LE whom may concern:
Be it known that I, SEBASTIEN ULnIoH, a citizen of the United States, residin at Akron, in the county of Summit and Estate of Uhio have invented certain new and useful Improvements in a Looking Attachment for Doors, of which the following is a specification.
This invention pertains to a locking attachment for doors the object being to provide a simple and strong device wherewith to fasten and look a door independently of the lock and key generally provided in doors. Door frames are usually provided with moldings or shoulderedL portions which make it difficult to use a supplemental locking device at the desired place opposite the ordinary lock and handle of the door, and my device is particularly constructed to facilitate attachment at that place and to effect square seating and a strong lock notwithstanding the limited room and varying forms and sizes of door moldings and projecting frame portions in general use.
In the annexed drawing, Fig. 1 is a horizontal section on the line 1-1 of Fig. 2 of a portion of a door and its frame, together with my locking attachment in looking position thereon. Fig. 2 is a front view of the parts shown in Fig. 1, and Fig. 3 is an elevation and section on line 83 of Fig. 2. Fig. 4 is an enlarged detail view, partly in perspective and partly in section, of the locking attachment. Fig. 5 is a front view of the yoke member alone. Fig. 6 is a perspective view of a modified form of locking plate and screw.
The invention comprises three main parts, a yoke member 2, a locking blade 3 having a round screw extension l, and a thumb-nut 5 adapted to engage the screw extension. Yoke member 2 is made of a flat piece of sheet metal of heavy guage pressed int-o a U-shape with a flat top portion 6 and with short. flat feet '7 at the bottom of each straight leg 8. A slot or opening 9 made in the flat top 6 at one side of its center and near one edge 10, and this feature is important in that it permits the device to be applied to door casings 11 wher the seating ledge 12 is exceedingly narrow on account of the molding or face board 13 which is generally secured to or forms an integral part of the door casing or frame, see Figs. 1 and 2.
. In seating yoke member against ledge 12 the flat feet 7 span the vertical joint between the door 14 and casing 11 and the major portion of the yoke overlaps the door and bears against it. The metal iamb or striking plate 15 which is usually countersunk within the inner face of the door casing has a bolt guiding tongue 16 projecting forwardly beyond ledge 12 and the legs of the yoke are spread apart sufficiently to permit the yoke to be seated flat against the ledge without interference with this tongue, see Fig. 3. In this connection it should be noted that the legs of the yoke are above and below the tongue in spanning the joint, and that the laterally offset slot or opening 9 in the yoke is directly opposite the door joint in line with the upper bolt opening 17 in jamb or striking plate 15. The lower rectangular opening 18 in the jamb or striking plate accommodates the locking bolt controlled by the key and the yoke and its locln ing parts are located above this bolt opening 18 so that a key may be used to lock the door independently of this device if desired.
But assuming that such a key is missing or the occupant of a room. or residence desires a safe-guard independently of the key and lock in the door, the locking blade 3 is thin enough to permit it to be placed in the space between the upright and the door in hook engagement with the amb or striking plate 15. This is done before the door is closed and upon closing the door the screw extension 4 is exposed to permit the yoke to be cleaved thereover in spanning seating position upon ledge 12 and the door. The thumb nut 5 may then be screwed upon extension 4: against the flat top of the yoke thereby effectively locking the door.
In Figure 6, I show a two part locking blade consisting of a hook plate 20 having a separate screw member 21 hinged thereto. This device may be used in lieu of locking blade 3, and being made in two hinged parts it is more easily applied to a swinging door where hand room is limited or crowded.
The locking blade is preferably made of sheet metal with two integral. wings or ears 19 bent in the same direction from opposite edges thereof to provide hooks at one side of the blade to permit them to be easily entered into hook engagement with the striking plate 15.
What I claim is:
1." A locking attachment for doors, comprising a flat, wide sheet-metal yoke having an opening in its cross connecting portion relatively near one side edge thereof and offset in respect to the longitudinal medial line, a blade having hook portions at one end integral with the side edges and bent at right angles to the flat side of the plate and a round screw-threaded extension at its opposite end adapted to project throughthe opening in said yoke member, and a thumbnut adapted to engage the-screw threaded extension of said blade.
2. A hinged door and acasing therefor having a striking plate provided with a boltrreceiving opening,-in combination with a pairof locking blades having hook por-- tions bent at right angles; from opposite side edgesadapted to occupy said opening in locking engagement with said plate and provlded with a screw-threaded extension adapted to "project beyond the face of said door and easing, a wide flat sheet-metal yoke having fiat sea-ting extremities adapted to seat upon said casing and door in straddling offset position to the jointand having an opening offset in respect to the longitudinal medial line of said yoke relatively near one sideedge thereof in its cross-connecting portion adapted to receive the screwthreaded extension of said lockingblade, and a thumb-nut adapted to engage said screw threaded extension.
In testimony whereof I afliX my signature in'presence of two witnesses.
SEBASTIEN ULRICH.
