6 Claims.
My invention relates to a strike plate for door locks.
One of the principal objects of this invention is to provide a strike plate for doors which is very simple and economical to manufacture, proportionate to its functions.
A very important object of this invention is to provide a strike plate which is particularly easy and economical to install whether th door is hung true or not, or even if it is warped.
An important object also is the provision of very simple means of securing the strike plate in position, and in which the securing means is substantially hidden from view, and also one which, when in place, is very strong and rigid and which will not readily deteriorate, loosen, or get out of order.
With these and other objects in view as will appear hereinafter, I have devised a strike plate for door locks, having certain novel features of construction and a novel combination with the door casing, or jamb, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawing and to the characters of reference thereon, which form a part of this application, in which:
Fig. 1 is a fragmentary transverse section of a door and a door casing or jamb, showing my strike plate installed in the latter, and showing by dot and dash lines, the means for marking the location of the strike plate from the holes in the door;
Fig. 2 is a side view of my strike plate shown mounted on the door casing;
Fig. 3 is an inner side view of the strike plate;
Fig. 4 is a sectional view of the strike plate mounted in the door casing, the section being taken through 4--4 of Fig. 1;
Fig. 5 is an elevational view showing the hole and slotted portion preparatory to the installation of my strike plate; and,
Fig. 6 is a perspective view of the device for marking the drill hole in the casing for the reception of the strike plate.
My strike plate is preferably molded in one piece and consists of a plate I, and an inward projection 2. The plate is elongated transversely and is semi-circular at the inner end, as indicated by The opposite or outer end, designated l is bent or curved inwardly, as in conventional construction, for engaging the bevelled end of a bolt (not shown) for causing retraction of the latter when the door is closed. The plate has a rectangular opening I at the semi-circular end for receiving the lock bolt. The projection 2, above referred to, is hollow, and is substantially in the form of an enclosure, having an opening the size and shape of the opening l and registering therewith. The surrounding walls of this closure are confined in'a circle of the radius of the semi-circular portion I.
In order to install my strike plate, a hole B is drilled in the side of the casing or'jamb B. A shallow slot or channel is made between the hole and the front edge of the casing or jamb. The projection 2 fits into the hole B while the plate I is positioned in and by the slot 13. This slot B permits the plate to be seated flush with the outer face of the casing. The edges or corners of the projection 2 preferably fit the walls of the hole B so as to seat the strike plate securely in the door casing.
The strike plate is secured in position by a single screw 3 which extends through the bottom wall of the projection 2. Thus, the strike plate is securely held in position even though the projection 2 does not extend to the bottom of the hole B as shown.
In the installation of the door lock C, the door D is provided with a large transverse hole D and a smaller hole D extending into the door from the free edge thereof and intersecting the former hole. I have provided a special marking-tool E, shown in Fig. 6, and by dotted lines in Fig. 1, which is inserted with an enlarged portion E into the hole D and then pressed with its rearwardly extending shank E into the door casing B. A point E at the axial portion and outer side of the enlarged portion E is pressed into the door casing, producing a mark for drilling the hole B above referred to, for the reception of the strike plate.
Though I have shown and described a particular construction, combination, and arrangementof parts and portions, and a certain combination with a door casing, and a particular method of installing the strike plate, I do not wish to be limited to the same, but desire to include in the scope of my invention, the construction, combination, and arrangement of parts and portions, substantially as set forth in the appended claims.
I claim:
1. In a strike plate of the class described, for a door casing having a relatively deep drill hole and a shallow transverse slot from the hole to the outer edge of the casing, a plate with a semicircular end, adapted to be positioned over the hole with the semi-circular end fitting the wall at one side of the hole, and the opposite end portion of the plate being adapted to fit the shallow slot, said plate being provided at its back side with a hollow bolt-receiving projection adapted to fit into the hole.
2. In a strike plate of the class described, for a door casing having a relatively deep drill hole and a shallow transverse slot from the hole to the outer edge of the casing, a plate with a semi-circular end, adapted to be positioned over the hole with the semi-circular end fitting the wall at one side of the hole, and the opposite end portion of the plate being adapted to fit the shallow slot, said plate being provided at its back side with a hollow bolt-receiving projection adapted to fit into the hole, the edge at the semi-circular end and the adjacent edges being inwardly bevelled.
3. In a strike plate of the class described, a long plate having substantially parallel opposite edges connected at one ;end with a semi-circular portion, said plate being provided intermediate its ends and at itsbackside-witha hollow oltreceiving projection,gsaid ,opPQSite edges and the edge ofithe SEmi-circular :portion being inwardly bevelled.
4. In a strikeplate of the class described for a door casing'having a relatively deep drill hole and a shallow transverse slot from the hole to the outer end of the casing, a plate with a semicircular end adapted to be positioned over the hole with the semi-circular end fitting the wall at one side of the hole, and the opposite end portion of the plate being adapted to fit the shallow slot, said plate being provided at its back side with a hollow bolt-receiving projection adapted to fit into the hole, a portion of said projection being substantially flush with the periphery of the semi-circular end and also adapted to fit the wall at one side of the hole.
5. In a strike plate of the class described, a long plate having substantially parallel opposite edges connected at one end with a semi-circular portion, said plate being provided intermediate its ends and atits back side with a hollow boltreceiving projection, a portion of the projection being substantially flush with the periphery of said semi-circular portion.
6. In a stike plate of the class described, a long plate having substantially parallel opposite edges connected at one end with a semi-circular portion, said plate being provided intermediate its ends and at its back side with a hollow bolt-receiving projection, said projection being substantially rectangular and two corner portions thereof being substantially flush with the periphery of said semi-circular portion.
