DOOR FRAME SETTING JIG Filed Dec. 2, 1966 I6 INVENTOR.

ELMER F. GIRARDIN 5g. Z.

United States Patent U.S. Cl. 29--200 4 Claims My invention is directed toward a door frame setting 11g.

It is an object of my invention to provide a new and improved door framing jig adapted for the quick and accurate setting of door jambs and similar frames.

Another object is to provide a new and improved door framing jig of the character indicated which can be used to set the jam or frame. v

Still another object is to provide a new and improved door framing jig of the character indicated which can be manufactured easily and inexpensively.

All of the foregoing and still further objects and advantages of my invention will now be explained with reference both to this specification and to the accompanying drawings wherein:

FIG. 1 is a perspective view of my jig in position installed in a rough opening; and

FIG. 2 is a front detail view of a portion of my jig.

Referring now to FIGS. 1-2, there is shown a door receiving opening formed in a wall by parallel vertical studs and 10 spaced apart resting on floor 12 and joined by a horizontal header 14.

My jig comprises a first vertical elongated member 16 having at each end extending horizontally from the same side thereof upper and lower horizontal extensions. Each extension includes a first horizontal member 18 secured to member 16 and having a centrally disposed horizontal slot 20. A second like horizontal member 18' is disposed behind and aligned with member 18 and has spaced apart transverse screws 21 extending horizontally and perpendieularly out of member 18 through the slot and held in position by wing nuts 22. Hence by use of screws and nuts 22, member 18 can be slid in slot 20 to elongate or shorten the horizontal extension and can be locked into place by the nuts. Alternatively both members can have aligned slots 20 with bolts 21 and nuts 22 extending therethrough. A second elongated vertical member 24 is disposed adjacent the free ends of both horizontal extensions.

In use, member 16 is disposed adjacent stud 10` with the upper extension in contact with header 14 and the lower extension in contact with the floor. First and second U shaped securing brackets 26 operated by thumb screws 28 are then used to secure member 16 to stud 10. The lengths of both extensions are then adjusted as described above to set the proper width of the jamb. Member 24 is then disposed adjacent the free ends of the extensions to be and the stud 10 and is secured to this stud by additional clamps or brackets 26. Member 24 carries horizontal an vertical levels 28 and 32 which are then used in skimming the structure level. The jamb is then held rigidly and securely for setting and nailing.

My invention saves time and money in use and further increases accuracy. It can be set and used by a carpenter without any assistance. It is light in weight and can be made of wood, plastic, metal or fiber glass.

While I have described my invention with particular reference to the drawings, my protection is to be limited only by the terms of the claims which follow.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A door frame setting jig adapted for use with a door recovery opening defined by first and second parallel vertical spaced apart studs resting on a horizontal floor and joined by a horizontal header, said jig comprising:

(a) a rst vertical elongated member adapted for detachable engagement with one of said studs;

(b) a second vertical elongated member adapted for detachable engagement with the other stud; and

(c) upper and lower horizontal extensions secured respectively at the upper and lower ends of the second member and extending toward the first member, the upper extension being alignable with the header, the lower extension being alignable with the lloor, each extension being adjustable in length.

2. A jig as set forth in claim 1 wherein each extension comprises rst and second horizontal members disposed one behind the other, the first horizontal member being secured to the corresponding end of the second vertical member, each horizontal member having a horizontal slot, spaced apart screws and nuts engaging said slots whereby the second horizontal member can be slid toward and away from the second member to shorten or lengthen the corresponding extension.

3. A jig as set forth in claim 2 further including bracket means detachably secured to each vertical member for detachably securing same to the corresponding stud.

`4. A jig as set forth in claim 3 further including horizontal and vertical levels secured to said first member for use in skimming.
