Referring'by numerals to the accompanying drawings, 10 indicates a rigidrectangular trame comprising a pair of vertically .disposed members 11 and a series of cross members 12, which latter are secured at their ends S to the respective vertical members 11. Each vertical member 11 has slidably mounted thereon and extending therethrough at a number of .points spaced from each other a q series of tubular members 14 which are disposed transversely of said members 11. The outer ends of these tubular members have iixed `,thereto side members 15.` Each side member 15 is arranged adjacent to vertical member 11 and is movable substantially in parallelism relatively thereto'.

The inner ends of tubular members 14 engage and slide upon guide vrods 16 which are fixed to and project Jfrom members 11 in opposed relation with the respective tubulary members 14. The inner ends of said transverse members 14- terininate short of the 0pposed vertical members 11 and interposed therebetween and threaded on the respective guide rods are coiled compression springs 17 which, when tubular members 14 are re leased. tend to move the side members 15 into extended positions away from frame 10. Preferably each end of tubular member 14: terminates in a collar 1d which provides an efficient bearing for the respective ends of spring 17 and also limits the outward movement of members 14C and 15.

Side members 15 can be held immovable either in expanded positions or `in retracted positions by locking bars 18. These bars are each disposed longitudinally of each vertical member 11 and areslidably mounted in bearings 11a extending transversely therefrom. At each point where bar 18 crosses tubular member 14: an opening 19 is formed in member 11 adjacent to bar 18 and the latter is provided at these points with inclined rearward ly presented projections orvcams 20 which extend inwardly into members 11 (see Fig. 7 These cams, when bar 18 is moved longitudinally, (in the present case upwardly) are brought against tubular members 14 and holdA the same against movement by frictional engagement as shown in Figure 7. i i

Each bar 18 is provided with a rack portion 18LnL with which is meshing a pinion 21 fixed to a shaft 22, which latter is journaled in bearing 23 arranged on one side of member 11. A hand wheel 24E is fixed to shaft 22 adj acent to pinion 21 so that by operating pinion 21, through said hand wheel 24, bail i8 can be actuated longitudinally either to'bring the cams 2() into frictional engagement with tubular members 14 and lock the respective side members 15 in position or to disengagel said cams from members 14 and permit the latter to move into extended positions under the influence of their respective springs. Bars 18 extend substantially the entire length of vertical members 11 and are adapted to engage all of the tubular members 14 arranged on that side.

Side members 15 are arrangedto contact with the vertical members of a door frame or other opening. The upper member of the door frame is engaged by a horizontally disposed top or end member 26 which is arranged above the upper end of frame 10. Ex-

` tending downwardly from top member 26,

near the ends thereof, are bars 27 which are slidably mounted in the upper ends of vertical members 11. A coiled spring 28 is interposed between the upper end of each vertical member 11 and the underside of member 26 so as to maintain the latter in yielding extended position. A screw 29 is screw-seated in the outer face of member 11 and extends thereinto and has its inner end adapted to bear against bar 27. rlfhus by turning said screw 29 in the proper direction the inner end thereof is brought against said bar 27, clamping the latter in position. Preferably a collar 8O is arranged on the upper end of each member 1l to provide eflicient bearing for the lower end of spring 28.

A horizontally disposed bottom member 31 having upwardly extending barsv B2 is arranged on the lower end of the 'frame and is moved into extended position by coiled springs 33. A. screw BA1 is arranged near the lower end of each member 11 for engagement with respective bar 82 whereby memberY 31 can be locked in proper position.

Members

15, 26 and 31 are used to define the exact size of the opening into which the closure member, suoli as a door, is to be fitted. ln order to provide clearance between the lower end of the door and the floor in cases where a rug is used, member 31 has mounted thereon a member 35 which is disposed parallel to the first member a suitable distance therebelow and is adjustable relatively thereto by means of screws 36. Thus by n'ianipulat ng said screws, 'the distance between

members

31 and 35 can be regulated so to keep member 8l a suitablev distance above the V'ioor and provide the necessary clearance between the door and the rug placed on the floor.

After the

members

15 and 26 are moved into extended positions, it is necessary to retract s(u d members before thetemplate can be used again. lnmy device, the means'for 'effecting this retractile movement consists of a single hand wheel 37 which is manually operable. Thus by turning said wheel in proper direction,

members

15 and 26 can be simultaneously retracted. This hand wheel is carried by a stud shaft 38 which is revolubly mounted in a bearing 39. rihis bearing is fixed to one of the cross pieces 12, as indicated at 39a. The inner end of shaft 38 carries a beveled gear Ll0 which meshes with a beveled gear Ll1. A vertically disposed shaft l2 extends substantially the entire height frame 10 and is `iournaled in bearings d8 formed on cross members 12 and iii a bearing dlllvformed in bearing member Beveled gear lll is fixed to said shaft 4t2 above beveled gear d() so that by actuating hand wheel 87., shaft 42 is rotated in the desired direction. 4

A stud shaft ed is fixed in bearing member 89 in axial alignment with shaft 88 and in opposed relation thereto.v A beveled Ll5 is arranged on saidshaft and meshes with beveled gear d1. A spur gear 16 is conjoined to beveled gear d5 e...d meshes with.

ment of the corresponding transverse members 14 in opposite directions.

Shaft 42 is provided with a series of beveled gears 48, similar to beveled gear 41, and each of said beveled gears 48 meshes with a beveled gear 49, journaled in a bearing 50 and having a spur gear similar' to spur gear 46 which meshes with rack portions 47 of the corresponding pair of transverse members 14 so that when shaft 42 is actuated by hand wheel 87, all of the transverse members 14 are simultaneously operated to extend or retract said members 15.

The operative connection betweenlshaft 42 and the top member 26 is effected by means of a beveled gear 51 engageable with the upper end of said shaft and a beveled gear 52 fixed to a horizontally disposed shaft 55, which. latter is slidably mounted in bearings 54 arranged on the upper ends of vertical members 11.

Gear 51 is revolubly mounted in a bearing l2a carried by the uppermost-cross member 12. Gear 51 is revoluble in said bearing but is held thereby against axial movement. Shaft 42 extends slidably through said gear and is provided with pins or diametrically opposed projections 55 which are adapted to be seated in diametrically disposed seats 56 formed in the face of gear 51 (see Figures 8 and 9). Shaft 42 is movable longitudinally and when it occupies .depressed or lowermost position, projections 55 are seated in seats 56 so that gear 51. is interengaged with said shaft and is capable of transmitting rotating movement to shaft 53. This shaft is provided near each end with a pinion 57 which meshes with a rack portion 58 of each bar 27. lllhen shaft 58 is actuated, bars 27 of member are caused to move longitudinally tirough the interengagement of gears 57 and rack portions 58.

ln order to permit side members 15 and top member 26 to move under the influence of respective springs into contacting posi-r tions with the walls of the opening, it is necessary to disconnect the driving connection between` the shaft 42 and the

gears

44, 48 and 52 so that the

transverse members

14 and 27 are free to move outwardly. To this end, shaft 42 is slidably mounted in its bearings and is movable upwardly by means of a handle 59.

Gears

41 and 48 being arranged above the beveled gears with which they are meshing are displaced upwardlv by the upward movement of shaft 42 and the transverse members 14 are not impeded in their outward movement.

VlVhen shaft 42 is raised, projections 55 carried by the upper end thereof are moved out of seats 56, thereby disengaging said shaft from gear 51. It is desirable to disengage gears 57 from rack portions 58 of bars 27, so. that member 26 can adjust itself freelyto the contour of the door lintel. ,Inorder'to' face 61 presented toward gear 52 and engaging a collar 62 fixed on said shaft 53. Thus when shaft 42 is raised, the cam face 61bears against thecorresponding face of collar 62,

thereby causing'longitudinal displacement of shaft 53 and the gears carried thereby.

As soon as shaft 42 is moved to its normal position, shaft 58 is restored, whereby bevelec gears 51 and` 52 Vbecome interengaged. Shaft 53'is restored to normal position, preferably by means of a coiled spring 68, one end of which bears against a fixed bearing 64 fixed to one side of member 11 and the other end of which bearing bears against a collar 65 .fixed to shaft 53. A coiled spring 66 is used to assist shaft 42 to retain normal position. @ne end of this spring bears against one of the bearings 50 and the other end of said spring bears against a collar 67 fixed on shaft 42.

The outwardly presented face A of each contact member is provided with a reduced portion B, thereby forming shoulder C. Zhen the template is placed within the door frame, "the face A is brought in contact with the face of the door frame member D (see Figure 14). lV hen the template is placed in position on the door, the edge of the reduced portion B is placed on the face of the door and a scriber or marker used to mark the outer face of said edge on the face of said door. Thus it will be seen that the door so marked is slightly smaller than the size of the opening as defined by the face A, and the difference between the tvo dimensions, as indicated by X in Figure 16, provides the necessary operating clearance between the door and the door opening.

The marker 69 comprises a blade 7 O attached to a handle 71. The shank of the handle is provided with an oiferhanging portion 78 which extends over the outer edge of the contact member and engages the inner face thereof so that the marker is held and guided in proper marking positiony thereon. Preferably the outer edge of blade 70 rides upon the shouldered portion C.

The marker is used only when the template is inposition on the door and is detached from the template after use.

The vertical members 15 are provided with hinge markers 74 by means of which the height ofthe hinge on the door jamb is marked. Each marker comprises a plunger 75 slidably mounted in a bearing formed on member 15 and provided on its outer end with a blade 76. This blade is'normally held in retracted position by means of a coiled spring 77 which is interposed between the bearing movement of the locking bar.

pression on the tace ot the j amb showing the exact location of the hinge.

ln the modiiied form shown in Figure 17, a locking bar 79 is shown` mounted on vertical member 1l. This locking bar is provided with a rack portion 8O which meshes with a pinion 81 manually operable by a knurled member .81"1. A plurality of screws 82 are screw-'seated in vertical member l1 and adapted, when turned in tlieproper direction, to move against the appropriatel member 14 and secure them in position. Each screw 82 is provided on its outer end with a pinion 83 which meshes with a rack portion 84 formed on locking bar 79. Thus when said bar is moved longitudinally all the screws 82 arev simultaneously actuated, either to lock the transverse members lll in position or to release them, depending upon the direction of The device is held in position on the door by a series of clamps 85. VEach clamp consists oi"- an arm 86 pivotally mounted at 87 on the inner side and near each end of each member l5. Arm 86 is considerably longer than the thickness of the door and the free end ot each arm is presented laterally and inwardly in spaced relation with the face of the door. A clamp screw 88 is arranged in said end and can be actuated to bear against the respective Jface ot the door and draw members l5 against the other face thereof and thereby securely hold them in position thereon.

The contact or

marginal members

15 and 26 are flexible so as to enable them to follow the contours of the walls ot' the door opening. As the bottom member 3l is generally not brought into contact with the floor or threshold member, this member can be rigid or have a lesser degree ot flexibility than the first mentioned member.

Each transverse member la is movable independently of the other members, thereby insuring the proper disposition of the side members l5. Vertical members 27 are also movable independently of each other as are also members 32 ot' the bottom member 3l. Thus it will be observed that the contact or marginal members are adjustable independently ot each other and that portions of said marginal. members are also adjustable independently of the remainder oit such members. This insures accurate litting of the door and registers any irregularities in the faces ot the door openings.

An important feature and a very decided advantage of my device the single manually operable member .tor retracting said marginal members l5 and 26. The bottom member 31 is not operatively connected to the restoring members since vit supports the entire device when the latter is located in the door openino'. Member 31 is adjusted only when it is desired to increase or decrease the height of the device. The lloor member 35 is disposed relatively to the member 3l to compensate for the thickness of the floor covering` near thel door opening.

The ends of the contacting or marginal members terminate short of each other, the corners ot' the door opening being delined by the extension ot the lines scribed on the face ot the door. This eliminates complicated corner construction of the template without impairing the usefulness thereof.` The template is of light construction and its operating mechanism is arranged so that it may be manipulated by one man in an eflicient .man-

ner. i
