Filed Aug. 24, 1959, Ser. No. 835,641 6 Claims. (Cl. 77-62) top of the drawer or door. So called finish carpenters usually install these drawer and door pulls, and in some large home building tracts a crew of finish carpenters does nothing else but install the cabinets and apply the hardware thereon.

, The present invention contemplates the provision of a drilling fixture for use in quickly and accurately installing door pulls on the doors of kitchen and other cabinets.

Another object of the invention is to provide a drilling fixture for use in drilling holes for the mounting screws for door cabinet hardware, and which will facilitate uniformly positioning the door pulls on a number of similar cabinet doors, either single or double.

Another object of the invention is to provide an im proved and simplified drill fixture for use in installing the door pulls on double cabinet doors.

vals to receive a positioning slide 17, which is insertable in any selected one of the slots 15.

A selected number of transversely aligned, symmetrically paired, drill guide holes 18 and 19 are provided in the

wing portions

12 and 13, respectively.

The slide 17 supports the fixture A in adjusted position on a corner of a door 20 as shown in FIG. 2, and, by using a selected pair of the holes 18 and 19 in the

wings

12 and 13, holes may be drilledin similar, but reversed,

. position in a pair of doors 21 and .22 .(FIG. 5). When I door pulls 23 and 24 are installed with their usual mountportion 17b. projects on the other side.

Patented July 4, 196 1 ing screws 25 inserted in a usual manner in these holes, the pulls will be in matching position.

Referring to the drawings in detail, in the fixture A the front plate 10 is of suitable, and preferably light weight material, such as, for example, aluminum alloy or plastic material. The narrow upper portion 11 of the front plate 10 may be integral with the pair of similar, oppositely extending

wing portions

12 and 13 at its lower end.

A plurality of similar, and similarly spaced, holes 18 and 19 of a size to receive a desired drill 27 therein, is provided in each of the

wing portions

12 and 13. Each of the holes in one wing portion, for example the hole 18a, is paired with a similarly located hole 19a in the other wing portion.

The rectangular back strip portion 14 is fixedly secured to the rear of the narrow upper portion 11 of the front plate 10, and is centrally aligned therewith. The back strip portion 14 may be either molded integrally with the front plate 10, or may be secured thereto as by screws 18 (FIG. 2) or a suitable adhesive material, not shown. The side faces 29 and 30 of the back strip portion are perpendicular to the rear surface of the front plate 10 and parallel to each other, and the axes of the drill'guide holes 18 and 19 are aligned to define a plane 31 perpendicular to the front plate 10 and the parallel side faces 29 and 30 of the back strip portion 14.

The slotted openings 15 through the back strip portion 14 are identical to each other, and are parallel to the plane 31 defined by the axes of the drill guide holes 18 and 19. The lower sides of successive slotted openings 15 are spaced from the plane 31 defined by the axes of the drill guide holes by selected measured increments, for example, one inch. The lowermost slot 15 in the illustrated form A of the invention maybe two inches from this line, since door pulls are not ordinarily mounted with their mounting screws closer than that to the top of; a door.

The positioning slide 17, with its flat, lower face 32, has a shank portion 17a of a size for fitted insertion into any selected one of the slots 15, preferably with a snug sliding fit so that it will not fall outby its own weight. A thicker head portion 17b is provided on the slide 17, which limits the insertion of theslide into the slots 15 to substantially the extent shown in FIG. 3. In this latter position of the slide17, the shank 17a projects outwardly from one side of the back strip portion 14, while the head By manually grasping the head portion 17b the slide 17 may be Withdrawn from any slotted opening 15 in which it may be inserted, and may be reinserted, flat side downwardly, into any selected one of the slotted openings .15. Thefiat under face 32 of the slide 17 will then be located a selected number of inches, or other selected incrementof measure, up from the plane 31 defined by the axes of the drill guide holes 18 and 19. An index number 33 is provided adjacent each slotted opening 17 indicating'its distance, inthe selected increments of measure, from the plane 31 of the hole axes. In using the fixture A it will be assumed that the three pairs of

holes

18a, 19a, and 18a and 18b, and 18c and are, respectively, one, one and one-half, and two inches from the side faces 29 and 30, respectively, of the back strip portion 14, and that the slotted openings 15 are spaced from the plane 3-1 of the drill guide holes 18 and 19 by increments of one inch, beginning at two inches. It will be further assumed that it is desired to mount the pair of door pulls 23 and 24 (FIG. 4) four inches down from the top, and two inches in from the free edges of the pair of

cabinet doors

21 and 22.

The slide. 17 would then be withdrawn from any other slotted holes, such as, for example, the one designated by the numeral 2 shown in FIG. 1, and would be reinserted in the slotted hole designated by the numeral 4. The fixture A would then be positioned on one of the doors in the manner shown in FIG. 2, with the slide 17 resting. on the top edge of the door, the side face 30 of the back strip portion '14 pressed firmly against the free edge of the door, and the wing portion 13 closely overlying the external face of the door. A drill 27 would then be inserted in the outermost hole 19c, which, as stated previously herein, is assumed to be the desired two inches from the side face 30 of the back strip portion 14. Using this hole 190 as a guide, the drill 27 would be driven through the door, thereby drilling a hole in the door. A usual door pull screw 25 would then be inserted from the inside of the door through the hole thus drilled, and screwed into the door pull 24 in a usual manner. The other door pull 23 would then be similarly mounted on the other, or left hand door (FIG. 4), using the corresponding hole 180 in the other wing portion 12. The door pulls 23 and 24 would thus be mounted symmetrically on their respective doors.

While the fixture A shown in FIGS. 1-3 and 5 may be used for a long time without damage providing the drill is inserted in the guide holes 18 or 19 before starting the drill, still it may be desirable to face the holes 18 and 19 with a suitable hard material, such as, for example, case hardened steel. In such case a bushing 34 of such material may be fitted into the holes 18 and 19. Such reinforcements may be desired particularly if the entire fixture A is to be made, for example, of unitary molded plastic material, which material is usually easily cut by an edged tool.

If it is desired to use door pulls such as that 35 shown in FIG. 6, and having two mounting screws, the fixture A would be used as shown in FIG. 2, wherein a first hole is drilled with the fixture in its solid line position, and a second hole is drilled with the fixture in its broken line position Aa. Obviously for such use, the slotted openings 15 would have to be spaced apart in increments corresponding to the spacing of the screw holes in the door pull 35 to be mounted.

The invention provides a simple, accurate and easily used drilling fixture, which greatly facilitates the mounting of door pulls, and which may be carried in a mechanics tool box where it occupies little space and is always ready for use.

While I have illustrated and described a preferred embodiment of the present invention, it will be understood, however, that various changes and modifications may be made in the details thereof without departing from the scope of the invention as set forth in the appended claims.

Having thus described the invention, what I claim as new and desire to protect by Letters Patent is defined in the following claims.
