After the frame setter has finished his job to the best of his ability, the door hanger must hang the door in the frame, and he attempts to shape the edges of the door so as to approximate the linear contour of the jambs and head of the frame. If the jambs are too narrowly spaced, a considerable amount must be planed off one of the door edges at considerable waste. If the jambs are warped, little can be done, and if they are not vertical, the edges must be planed to different depths along the edge to attempt to follow the inclination of the jamb.

The present invention provides an elongated vertical standard, generally designated 29 that is absolutely straight along its outer edge.

Inasmuch as the standard 29 must extend from substantially head 9 to floor 6, a distance usually in excess of six feet by about eight inches, or 6 feet, 8 inches, the same is preferably made in two portions, there being an upper portion 2| and a lower portion 22. These portions are preferably made from a good hardwood, such, for example, as mahogany. This hardwood is initially in strips or pieces that may be about one and one half by three and one half inches in cross sectional contour, and across one of the corresponding edges of said strips are metal face plates or strips 24, 25 respectively secured to strips 2|, 22 (Fig.

The strips or face plates 24,. 25 are preferably substantially wider than the edges of the wooden pieces 2|, 22 to which they are secured, hence they will extend oppositely outwardly of the opposite sides of said pieces as indicated at 2B, 21 in Fig. 2. The projecting portion 26 of each strip 24, 25 terminates in a right angle flange 28, and these projections are respectively backed by strips 29 that are triangular in cross sectional contour, and that may also be of wood and glued or otherwise secured to the opposite sides of the strips 2|, 22. These backing pieces merely fill the reentrant angles between the said opposite sides of the strips 2|, 22 and the projecting portions 26, 2'! of the metal strips 24, 25. The portions 2'! may continue over the outer exposed side of the strips 29 that are against said portions, as best seen at 39 (Fig. 3). It is to be understood that the triangular strips 29 and the flanges 28 do not continue past the adjacent ends of strips 2|, 22 when the latter are in end to end abutting relation (Fig. 5).

The strip 22, which is the lowermost strip of the pair, has an upwardly projecting dowell 32 at its upper end that is adapted to fit into a complementarily formed recess in the lower end of the upper strip 2| for securing said strips in longitudinal alignment with their outer corresponding sides and edges flush at the juncture between said strips. The lower end portion of the upper strip 2| is provided with a cross bolt 33 and the upper end of the upwardly projecting dowel 32 is formed with an upwardly opening slot 34 (Fig. 5) that is adapted to pass said bolt when said strips are together in alignment. Upon tightening the thumb nut 35 on said bolt, the two strips 2 I, 22 will be securely locked together.

The two oppositesides of the strips 2 I, 22 along the edges remote from the metal face plates 24,

25 are formed with outwardly opening grooves 36 (Fig. 3) that are rectangular in cross sectional contour, and that extend parallel with the edges and sides of the strips 2|, 22. The grooves each of the sides of strips 2| are in longitudinal alignment with the corresponding grooves in lower strip 22. The said grooves in the upper strip 2| have rectangular channel members 38 fitted therein with their open sides opening oppositely outwardly relative to the strip 2 I. Lower strip 22 has similar channel members 39 fitted in the grooves in said lower strip.

Channel members 38 terminate short of the lower ends of the grooves in which they are secured while the upper ends of the channel members 39 (Fig. 5) carried in the grooves in the lower strip 22 project upwardly, and are adapted to abut the lower ends of channels members 36 when the strips 2|, 22 are in longitudinal alignment. Thus the channel members 38, 32 are definitely in alignment at their junctures. Inasmuch as said channel members constitute guide ways for slidably retaining a gauge-arm on the standard 29 for sliding the length of the latter, it is essential that I the juncture between the channel members be in absolute alignment when the strips forming said standard are secured together. Screws 46, 4| may respectively secure the upper ends of channel members 38, 39 to the adjacent end portions of strips 2 I, 22 as seen in Fig. 5. This structure at the joint between strips 2|, 22 also materially contributes to the rigidity of the joint.

While, as above mentioned, the separation of strips 2|, 22 is made possible by the central joint connecting them, it is also submitted that this structure materially increases the accuracy of the standard as a straight edge, which is highly desirable. A single strip of metal or wood that is over six feet in length and that remains straight, is almost impossible to obtain, whereas it is relatively simple to provide a straight piece that is no more than three or four feet in length, and such shorter pieces will not tend to warp nor to become distorted if selected with reasonable care.

The opposite sides of the strips 2|, 22 may be relieved slightly by shallow central grooves or recesses 45 extending longitudinally thereof, and which recesses also provide finger grips for easily holding the standard by the hand.

The upper piece or strip 2| is preferably formed with a through opening 26 that extends longitudinally of said strip, and which opening is slightly below the eye level of the average man standing beside the standard when the lower end of the latter is upright and is supported at its lower end on the floor 6.

Extending across this opening and secured to said strip 2| at their ends are a pair of horizontal spirit levels 48, 49 (Fig. 5) that extend at right angles to each other and that are respectively parallel with two adjacent right angle sides of the strip. These spirit levels are fully protected against injury, as they are within the planes of the opposite sides and edges of the strip 2 I.

A bracket member 59 (Fig. 1) is provided or formed with upper and lower pairs of shoes 5|, with the shoes of each pair being inopposed relation (Figs. 1, 2) and fitting within the oppositely outwardly opening channel members 38, 39 carried by the standard 29 for sliding longitudinally of said standard. This bracket mem ber carries an arm 52 that extends at a right angle to the standard 29, and which arm is in two sections made up of a horizontally elongated laterally opening channel member 54, being a vertical, horizontally extending bottom or closed side 55 (Fig. 4), and upper and lower sides 5t, 5'! that extend convergently in direction transverse- 1v 0? th le g h oi the arm and away from the lIDBI'm-nd imwenredeeszozt the-hottormfiiwanda striptelescopicallymlidalblein-sagidzchannelm ber aswillbeilater described.

From the foregoing, 'itwill dbe. seen "that the strip. ill-sand zclrannelzmemben 51 provide two telescopic sections of: anarm that extends at rightangles to the-standard.- 29. and 'thati'the upper/edge of the channel. member omsectiorr 5d and the face plates-.24; .2 5 on "standard. 20 may simultaneously engage the. laterally inwardly facing 1 side of either :of the .jambs 1.5 8. and the lower surface of the head fil zwhen thefloracket carrying the section 15 3 is .atthe top of thestandand. as .seen: in Fig. l.

When the inner end of the strip 59; is evenwiththegraduation 36 or 3, according to whet-her thegraduations are in inches or in feet, and'fracti-onsthereof, the distance between the said oppositely outwardly facing surfaces o; said plates along al-i-or-izontal line will be thirty-sixinches or three feet. Thenext :step .setting the. door. .frame is to position the lower end of the standard 20 on the floor or sill adjacent one of the jambs. A downwardly directed pointed projection 14 011 the lower end of the standard, will engagethe floor to prevent slippagelof-said-lowerend.

late'will e a echecking operation; This may be done by placing the standard against jamb 8 and along the edge opposite the one that is shown as being engaged at the present time by flange 12.

The nailing of ajamb 8 to the member 2 that is alongside the same is readily accomplished during the procedure of moving the arm 52 vertically while flange 12 engages the edge of said jamb for the reason that there is ample space alongside the plate 70 for nailing. When the gauge is removed, and the jambs are set, another nail may be driven through the jambs and into members I, 2 to complete the proper degree of securement between said jambs and the building frame members adjacent thereto.

The operation of setting the jambs is one that is quickly performed and with the greatest accuracy. The door to be hung is, as has been explained, relatively accurate in its dimensions, hence the minimum amount of work remains for properly hanging the door. In ordinary practice, the Workman setting the jambs will take substantially less time to set the jambs by use of the present invention, than formerly, and a much higher degree of accuracy is obtained, thereby making it possible for the person hanging the doors to complete his work in a fraction of the time heretofore required, and to accomplish it with a much greater degree of accuracy than by the conventional methods;
