Apm'ilil 3? J. BAUER 23A ROUTER DOOR LATCH AND STRIKE PLATE TEMPLET SET Filed Jan. 5, 1955 INVENTOR. Joseph Bauer ATTD RN EYS United States Patent ROUTER DODR LATCH AND STRIKE PLATE a TEMPLET SET This invention relates to a methodof and apparatus for locating and positioning latches, locks and strike plates in a door or door jamb. I

The object of the invention is to provide a templet set which permits locks or latches and strike plates to be located in a door or a door jarnb without the necessity of chopping a recess in the door with a hammer and chisel.

Another object of the invention is to provide a router door latch and strike plate templet set which includesan alignment plug that has a pin extending therethrough, there being a templet providedwith a recess for receiving therein the plug, so that when the plug is removed a tool can be used for mortising the door or door jamb so that clearance or a cutout can be provided in the door or door jamb without the necessity of chopping with a hammer and chisel.

A further object of the invention is to provide a router door latch and strike plate templet set which is extremel simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout the same:

Figure 1 is a fragmentary perspective view illustrating a portion of a door, showing the holes in the door and showing the preparation of the door for using the present invention.

Figure 2 is a perspective view of the alignment plug.

Figure 3 is a perspective view with parts broken away and in section showing the alignment plug having its pin extending into one of the holes in the door.

Figure 4 is a perspective view illustrating the latch templet in place on the end of the door and with the alignment plug removed.

Figure 5 is a perspective view of a modification showing a templet for use in providing a cutout in a door jamb whereby a strike plate can be mounted in the door jarnb.

Referring in detail to the drawings, the numeral designates a portion of a door which is to be mortised for insertion therein of a door latch or lock such as a lock of the tumbler type. In using the templet set of the present invention a hole 11 may be drilled or otherwise formed in the door 10 and the hole 11 may extend in through one side of the door. A second hole 12 may extend into an end or edge of the door as shown in Figure 1, and the hole 12 may be of smaller diameter than the hole 11, the

holes

11 and 12 being arranged so that their longitudinal axis is arranged at right angles with respect to each other.

After the

holes

11 and 12 are drilled in the door 11 an alignment plug 14 is used. The alignment plug .14 can be made of any suitable material and includes a flat plate 15 which has its corners rounded as at 16 for a purpose to be later described. A pin 17 extends through the plate 15 and can be secured thereto in any suitable manner. One end of the pin 17 is adapted to be snugly seated in the hole or opening 12, while the other or outer 2 end of the pin 17 is adapted to be used as a handle as when the plug is to be removed.

The templet set further includes a router latch templet which is indicated generally by the numeral 18, and the templet 18 is in the nature of a flat plate which is provided with a recess or cutout 20 that snugly receives therein the plate 15 of the alignment plug I l. The corners of the recess 26) are also rounded as at 21. The numeral 19 designates suitable securing elements such as screws which can extend through apertures in the templet 18 for releasably or detachably connecting the templet 18 to the edge of the door 10. After the screws 19 are in place, the plug 14 is removed by gripping the handle 17 and then suitable router toolcan be used for mortising out the door to provide space for thedoor latch and then the screws 19 and templet 18 can be removed.

Referring to Figure 5 there is shown a modification wherein there is illustrated atemplet for forming a mortise in adoor jamb 27 so that a strike plate can be connected to the jamb 27. Thus, in Figure 5 the numeral 22 designates a strike plate templet which may be detacha'bly connected to the jamb 27 by suitable securing elements such as nails 23. The templet 22 is provided with a recess or cutout 24 which is adapted to receive the plate 15 of the alignment plate 14. A hole 28 is drilled in the jamb 27 for receiving the inner end of the pin 17. The templet 22 is constructed so that the corners of the recessed portion 24 are rounded as at 25, and there is further provided in the templet 22 a cutout portion 26 since in a strike plate, a projecting portion extends outwardly and this projecting portion will extend through the space in the door j-amb provided by the cutout 26. With the templet 22 in position, a suitable router tool can be used for mortising out the door jamb to provide clearance for the strike plate and then the templet 22 is removed from the jamb, after which the strike plate is mounted in the jamb.

From the foregoing it is apparent that there has been provided a method of and apparatus for use in mortising doors and door jamhs so that it is not necessary to use a hammer and chisel to cut out the door or door jam b. In use, the

holes

11 and 12 are initially formed in the door 10, then the plug 14 is arranged so that the pin 17 extends into the hole 12. The hole 11 is: adapted to b used for receiving the tumbler of a latch of conventional construction. After the plug 14 is in position as shown in Figure 3, the templet 18 is positioned over the plug 14 so that the cutout 20 snugly receives therein the plate 15, the rounded corners 16 of the plate 15 snugly seating in the rounded corners 21 of the templet 18. Then, the handle 17 is gripped and the plug- 15 is removed leaving the templet 18 against the end of the door as shown in Figure 4 so that suitable securing elements such as screws 19 can be used for temporarily fastening the templet 18 to the end of the door. Then, a suitable tool which may be power driven is used to cut out the space in the door exposed by the cutout 20 and due to the provision of the rounded corners 21 the tool can be easily worked or extended through the cutout 20 without having sharp edges to encounter. When the cutout has been formed at the sufficient depth, the screws 19 and templet 18 are removed leaving a cutout which is of the same size as the cutout 20 and this cutout in the door can be used for receiving the usual la-tch plate.

In Figure 5 the templet 22 can be used. in lieu of the templet 18 so as to form an opening in the door jamb 27 which has a shape that corresponds to the

cutouts

24 and 26. This configuration provides clearance for the usual strike plate which is mounted in the door jamb 27 after the templet 22 is removed.

The size of the parts can be varied as desired. With the present invention doors and door jambs can be mortised easier and quicker without the necessity of chopping out the door with a hammer and chisel. Furthermore, due to the fact that the openings in the templets have rounded corners, the plates which are inserted in the openings in the door or door vjamb .Will also have rounded corners so that they will be much more attractive and modern in design. Instead of using nails or screws for connecting the templets to the door or jamb, clamps can be used. Furthermore, by using a router tool, a more uni'form cut in the door will be provided.
