5. Claims. 1 This invention: relates 'to-doorxfitting. j igs: .and more: particularly to a device ofithi's typerhaving guide; means. thereon for: facilitating shaping; of the edges and/or ends of a door in conformity with an opening into WhiChaitiStOifiI..

.Ingeneral, the; present invention is associated with an adjustable frame for obtaining a template. of: a. door opening; Such types ofiadjust- 'ablez frames are. not basically new but-heretofore the. template. created therebywastuseful; only as a scribingguide requiring compensationifonclearances; later" required between the door. and: the frame.v In other words, to compensate-for such clearances with they priornadjustable frames; the latter had to be-placedl overithe door to bescribed and the latter scribed along one edge afterwhich the adjustable frame had: to bershifted laterally of the'door: and resetrelative thereto beforescribing. the other edge of. the door; Thus it. willabe seen that the human element. entered into: the final; result and, consequently error could. occur.

The; present invention contemplates the elimination of. error due to resettingof' thetemplate or adjustable frame. andhasxas its: psincipal obijeict the provision of a guide means for a template whereby bothedges: of a door can be shaped without resetting of. the templateaor adjustable frame relative thereto.

Another object is to provide an adjustable frame with templateedges adaptedto-conform to-any deviations, arcs or curvatures in a: door frame relative to plumb.

It is anotherobject to iprovidea door jig with laterally adjustableslides; having. their:outer ends pivotally associated. with flexible; template edges and a: guide rail paralleling the latter.

Theseand other objects andadvantages ofw-the present invention will become apparent the followingv description when read in the; light. of the. drawings in which:

'llheseilaterally :extendable slide imem- Ebers 2"!+-'-28 tare guidediz'imz laterali sliding movement relative to the intermediate member I6 within guideways 30 formed on the solid transverse portions 20 of the intermediate member l6. In addition to the foregoing guide connection to the intermediate member, each slide 21-28 has a longitudinal slot formed therein for receiving a bolt 29 having its head end embedded in the intermediate member as seen in dotted lines Fig. 2. The outer ends of the bolts 29 are threaded and each carry a wing nut 3| by which the slides 21-26 can be secured in lateral adjusted position with respect to their respective guideways. outer end of each of the slide members 21-28 is provided with an aperture through which a threaded bolt 32 extends. The head end of each threaded bolt 32 is anchored suitably to its square cut head being seated well into the

guide mem ber

25 or 26 as the case may be.

Each of the threaded bolts 32 carries a wing nut 33 by which the free ends of the slide members 21-28 can be suitably secured relative to the adjustable side edges 25-26. However, when the nuts 33 are loosened there is pivotal action between the ends of the slide members 21-28 and their point of connection with the side edges 25-26.

For purposes of the present invention, the adjustable side edges 25-26 also carry a corresponding guide rail 35-36 respectively having a side edge 35'-36' respectively, running parallel to the outer edge 25'-26 respectively of the guide or side edges 25-26. As illustrated in the drawings, these guide rails 35-36 are so disposed that the bolts 32 extend therethrough so that any outward thrust of the slide members 21-28 during adjustment of the door jig within the opening I is impressed upon the guide members 35-36 as well as the side edges 25-26 of the door jig. In this manner the edges 25-26 are being pressed firmly against the inner faces of the side edges of the door frame l0 so as to form a template of any irregularities, curvatures or angular shapes therein.

In order to render the adjustable side edges 25-26 flexible for the purpose aforesaid, each side edge 25-26 is recessed on its inner face as at 40. This is done to narrow down these adjustable side edges at a plurality of points along their length, namely between the points of pivotal connection thereof by way of the bolts 32 with the free ends of the respective slides 21-28. In this manner, the adjustable side edges 25-26 are made springy so as to bow or curve as well as slant into any counter or shape as may occur on the inner faces of the side jambs A or B of the door frame l0. It will thus be seen that in the setting of the door jig within a particular door frame, some of the transverse slide members may extend a greater distance from the intermediate member 16 than do others of the slide members. In this manner, the guide rails 35-36 are correspondingly curved so as to run substantially parallel with the outer or template edges 25'-26' of the adjustable side edges 25-26 of the door jig.

After the workman has set the door jig properly within the opening provided by the door frame It, the jig l becomes a template conforming substantially with the opening provided by the frame I0. The jig member is then slid out of or withdrawn from the opening, all of the wingnuts being fastened down tightly so that the entire jig is now a fixed template ready for positioning on a door D in the manner as shown in Fig. 4. In this connection, the door jig I5 The which now comprises a template is placed upon the door substantially centrally thereof so as to leave adequate material beyond the template edge of the jig. The jig is then clamped down firmly upon the door D in the manner as shown in Fi 4.

The rough door D upon which the jig has been placed (Figs. 4 and 5) will extend slightly beyond the template edges of the side edges of the door jig and these extended edges of the door must now be cut down to conform to the shape of the template edges 25'-26' of the door jig. This is done by the use of a power tool such as an electrically driven plane illustrated at 50 in Figs. 4 and 5. This plane 50 is provided with a guide member 5| adapted to lie upon the upper front face of the respective side edges or 26 as the case may be when the plane is applied to the door edge that is to be cut. This guide member 5| is of a dimension calculated to span the entire upper surface of the door

jig side edge

25 or 26 and ultimately bear against the edges 35'- 36' of the

guide members

35 or 36 on the tem-- plate.

As illustrated in Fig. 5, the plane is adapted to take a depth of out upon each stroke of the plane member along the edge of the door until the guide member 5| of the plane engages against the edge 35 or 36' of the

guide member

35 or 36 as the case may be. The depth of cut taken by the blade of the plane as illustrated in dotted lines in Fig. 5, is such as to allow for the clearance required, for instance, of an inch at each side of the door when the latter is ultimately placed within the frame ID for hanging thereon.

As previously stated, the adjustable side or template edges 25-26 of the jig of the presentinvention are adapted to bow or curve in conformity with any curvatures or angles in the side walls of the door frame as created by the wedge members when the door frame is set in place, or as caused by any warping of these side members of the door frame, after it has seen set into the opening I I. Consequently, since the edges 35-36' of the guide rails 35-36 are disposed in parallelism with the template edges 25'-26 of the side edges 25 and 26, it will be seen that the guide member 5| on the plane 50 following any of the curvatures affected on the guide members 35-36 will reflect such curvatures into ultimate cuts made by the plane to the depth of the dotted line as indicated in Fig. 5.

Consequently, once the plane 50 has been run over the door edge in accordance with the guide edge of the

particular guide rail

35 or 36, the door will fit perfectly into the opening from which the template was made on the particular door jig. Moreover, since both side edges of the door may be planed without any readjustment or resetting of the door jig relative to the door, it will be seen that the ultimate cut of both edges of the door will reflect the exact shape of the door opening as formed along the inner surfaces of the side jambs A and B as well as the head H- of the door frame 10.

In connection with the latter, it will be noted that when the particular door jig has been set into the opening provided by the frame [0, the

pedestal member l8 being pressed firmly down against the floor will cause the upper end of the jig to bear tightly against the head H of the door frame H]. In this manner, the head of the door can be scribed accurately to conform to the line at which the door should be cut in order to fit within the opening provided by the frame.

Moreover, and by the same token, since the door jig l has been pressed firmly up against the edge of the opening provided by the frame Hi, there will be sufiicient space allotted at the lower end of the side edges 25-26 to enable the workman to scribe the slab door adjacent its lower end as indicated at 56 (Fig. 4) so that the door can be cut at its lower edge with a saw to line up with the floor and have sufficient clearance therefrom to enable the door to swing in and out of the opening after the hinges have been set to the same.

While I have described the door jig embodying the present invention in specific detail, it will be apparent that the same may be varied, altered, and/or modified without departing from the spirit of my invention.
