GRUMBACH A TTOR/VE Y5 BACKGROUND OF THE INVENTION In fitting mortise locks to wooden doors, it is necessary for the lock installer to form a mortise or cavity in the front surface of the door-stile to a certain depth and over a given vertical distance, the mortise itself generally taking the form of an elongated slot for accomodating the mortise lock. For the average carpenter or lock installer, the forming of such mortises is a time consuming operation and requires careful measurements to assure that the slot is centered. While there is existing machinery for fonning the desired slot, such equipment for making mortises is normally beyond the practical reach of an average lock installer. As a consequence, mortise locks themselves are losing favor in spite of their superior qualities.
BRIEF DESCRIPTION or THE PRESENT INVENTION The present invention provides a mortising device which greatly simplifies the forming of mortises in door-stiles without requiring expensive machinery and which is sufficiently versatile as to be useful for all makes of wood door mortise locks. Further, the device can be produced at a low enough cost to be practical to the average lock installer.
More particularly, the mortising device comprises a frame means positionable on the door-stile. A guide means in turn is mounted on the frame means for vertical movement and is arranged to support a drill holder for movement towards and away from the door-stile. With this arrangement, a series of round holes, slightly overlapping, may be drilled in the end of the door-stile. The uncut waste between the round holes can easily then be cut away by moving the supported drill vertically along the length of the mortise leaving clean straight sidewalls.
In accord with an important feature of the invention, the drill holder takes the form of a U-shaped yoke member, the yoke arms being receivable in suitable slots in the vertical guide means. These slots provide for the in and out guided movement of the drill holder. The drill itself is rotatably mounted between the arms of the yoke in parallel relationship thereto but slightly closer to one yoke arm than the other. The yoke can thus be removed from the slots, turned over, and the yoke arms reinserted into slots so that a mortise can be formed at the exact center of either of two door-styles of widths differing by twice the amount that the axis of the drill is closer to one of the arms the other. Since most wooden doors are provided in two standard widths, the device is thus useful in all normal situations for forming a desired mortise.
BRIEF DESCRIPTION OF THE DRAWINGS A better understanding of the invention will be had by referring to the accompanying drawings, in which:
FIG. I is a perspective view of the mortising device of this invention preparatory being secured to a doorstile for forming a mortise;
FIG. 2 is an enlarged fragmentary view partly in cross-section taken in the direction of the arrow 2-2 of FIG. 1;
FIG. 3 is another enlarged fragmentary view partly in cross-section taken in the direction of the arrow 3-3 of FIG. 1; and,
FIG. 4 is an end view of a portion of a door-stile in conjunction with certain components of the device useful in explainingan important feature of the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 1 there is shown a portion of a door-stile l0 illustrating in dotted lines a partially completed mortise 11. The mortise device itself is shown exploded away from the door-stile 10 and comprises a positioning frame 12 having opposed parallel plate members 13 and 14 for receiving and sandwiching the door-stile 10 therebetween. The frame includes upper and lower cross members 15 and 16 for securing the plates 13 and 14 in their spaced opposed parallel positions.
In order to accomodate door-stiles of different widths, there are provided upper and lower holding pads 17 and 18 on the inside surface of the plate member 14 with cooperating exterior tightening knobs 19 and 20 for urging the pads 17 and 18 against the side of the door-stile to securely hold the positioning frame to the door-stile when sandwiched between the plate members.
A guide means in the form of a yoke carriage 21 is slidably coupled to the frame 12 for vertical movement along the length of the frames. As shown, this carriage includes guide slots 22 and 23 adjacent to the outside surfaces of the plate members 13 and 14. A tool holding means in the form of a yoke member includes yoke arms 24 and 25 receivable in the guide slots 22 and 23 of the carriage. The cross portion 26 of the yoke member defining the U-shape rotatably mounts a drill spindle 27 terminating at its inner end in a drill bit 28. The axis of rotation is indicated at A and lies between and parallel to the yoke arms 24 and 25. With this arrangement, the drill may be moved inwardly towards or outwardly away from the door-stile by sliding the yoke member in the guide slots 22 and 23 as indicated by the double headed arrow 29. It will be noted in FIG. 1 that the axis A of the drill is positioned slightly closer to the yoke arm 24 than to the yoke arm 25, the respective distances being indicated at DI and D2. The purpose for this off centering of the drill axis will become clearer as the description proceeds.
Referring particularly to the carriage 21, the structure includes a vertical guide plate 30 which overlaps the forward edge of the plate member 13. This guide plate in cooperation with a second guide bar 3| secured to the carriage 21 provides for precise vertical sliding movement of the carriage 21 along the plate members, the guide plate 30 and the guide bar 31 stabilizing the carriage 21 in all vertical positions such that the inward and outward movement of the yoke member and thus the drill will always be normal to the front end of the door-stile.
To control vertical movement of the carriage 21 in a precise manner, there is provided a rack 32 secured to the outer side of the plate member 13. A suitable pinion operable by knob 33 permits precise upward and downward movement of the carriage 21 relative to the plate members. A stop 34 may be clamped to the lower portion of the rack 32 as illustrated in FIG. 1 to limit the downward movement of the carriage 21. This stop 34 may be repositioned on the rack so that the limit of downward movement can be changed as desired.
FIG. 2 illustrates in detail the rack 32 wherein there is shown a cooperating pinion member 35 operable by the knob 33 of FIG. 1. The guide plate 30 and guide bar 31 can be integrally formed with or simply welded to the adjacent portion of the carriage 21 as indicated by the cross hatching.
FIG. 3 shows in greater detail the means for urging the holding pads against the side of the door-stiles to lock the frame member in a desired position. As shown, the tightening knob 19 is secured to a threaded shaft 36 passing through a threaded opening 37 formed in the frame such that threading movement of the shaft will urge the pad 17 into or out of engagement with the side of the door-stile. The knob 20 and corresponding holding pad 18 are similarly designed.
The particular feature of off centering the axis A of the drill with respect to the yoke arms 24 and 25 heretofore referred to with respect to FIG. 1 will be understood by now referring to FIG. 4. With the drill axis A closer to the yoke arm 24 a round hole indicated by the solid line I] will be formed in the front end of a door-stile having a standard width of 1% inches. If now the yoke arms 24 and 25 are removed from the guide slots 22 and 23 in FIG. 1, turned over, and reinserted in the guide slots, the drill axis will be spaced further from the left side of the door-stile as viewed in the drawings thereby resulting in a round hold depicted by the dotted lines 1]. This hole position would be used for the second standard width door of 1% inches as indicated at the D. Thus, mortises can be formed at the exact center of either of two door-stiles of widths differing by twice the amount that the axis A is closer to the one arm than the other. In the particular example shown in FIG. 4, the difference in spacing; that is, the distance D2 minus D1 would be 3/ l 6 inch.
OPERATION The operation of the mortising device will be evident from the foregoing description. To cut a mortise in the form of a vertical channel or slot, the lock installer will first sandwich the doorstile 10 between the plates 13 and I4 and then tighten the knobs l9 and to snuggly secure the frame 12 to the door-stile in a desired position.
Thereafter, the worker can simply chuck to the spindle 27 a conventional power tool to rotate the drill bit 28. A series of round holes, slightly overlapping, as indicated by the dotted lines for the partially completed mortise 11 in FIG. 1 are then formed by successively moving the carriage 21 in a vertical direction by the knob 33 and effecting in and out movements of the yoke member 26, the extent of inward movement being determined by the desired depth of the mortise.
The uncut waste between the round holes can easily be cut away by moving the drill bit 28 along the length of the mortise while it is rapidly rotating within the cavity thereby leaving clean scraped side walls.
If the door-stile is of a standard width D of I36 inches, the yoke member 26 will be received in the guide slots 22 and 23 as illustrated in FIG. 1 wherein the drill axis A is closer to the yoke arm 24 than to the yoke arm 25. The dimensioning of the yoke is so designed that the round hole cut in the end of the doorstile will be exactly centered for such a 1% inch width door. On the other hand, if the door is of a second standard type having a width of D of 1% inch, the yoke member 26 is removed and turned over, as described heretofore, and the yoke arms 24 and 25 reinserted in the slots thereby positioning the axis of the drill to assure an exact center cutting of a round hole in the wider door.
The stop 34 described in FIG. 1 may be initially positioned on the rack such that the limit of vertical movement of the carriage 21 is defined by the desired vertical dimension of the mortise.
From the foregoing description, it will be evident that the present invention has provided a greatly improved mortising device which can be economically manufactured and easily used by the average lock installer.
