CARPENTER'S TEMPLATE Filed April 13, 1955 2 Sheets-Sheet 2 INVENTOR STEVENS w. BOATWRIGHT ATTORNEY Patented Apr. 20, 1954 UNITED STATES PATENT OFFICE 9 Claims.

The present invention relates to a carpenters tool or template for locating and marking hardware locations on doors or the like.

Although templates have heretofore been used they have not been satisfactory to perform the necessary functions for doors of different sizes and have not met with approval by the trade.

This application is acontinuation-in-part ,of my pending application Serial No. 225,805 filed May 11, 1951, entitled the Carpenter's Template.

An object of the present invention is to provid a deviceparticularly useful for carpenters for accurately marking the, location of a door lock, hinge, or other door hardware used in building construction.

A further object is to. provide locating means for door locks of different dimensions so that a single tool may be used for doors of different sizes.

Another object is the provision of a tool having a removable lock location mean which may be secured to the tool atone time and removed therefrom at another.

A further object is to provide a tool for marking the hinge location and'the lock keeper location on a door jamb as well as the door stop strip and door jamb trim.

Other and further objects'will appear upon reference to the specification and the drawing, wherein:

The present invention broadly includes a front plate with a side plate extending at substantially right angles thereto with an opening in the side plate for marking the location of a door lock. The front plate is provided with a rib of greater thickness than one plate of a hinge and such rib separates the front plate into two areas, of a size useful in marking hinge locations of different sizes of hinges. The rib includes a scriber edge for marking the amount of a door to be cut out for the butt hinges used therewith. Thefront plate may also include an opening for location for other types of door locks as well as apertures for locating other parts of door hardware. A removable element is supplied for attachment to the side member for locating a specific part of a door lock.

Referring more particularly to the drawing a front plate I 0 of metal or other suitable material has integrally formed therewith a side plate I I extending at right angles to the front I0 and including top and bottom bar I2 and I3 with rear bar I4 and front bar I5, the bar I5 bein integrally attached to the front ID. The front II] has its side edge I 6 projecting beyond the side member II by an amount substantially equal to the thickness of the front member. An integral rib I1 is formed on the front surface of the front member and extends from edge I6 to edge 24R and has its lower edge substantially parallel to the bottom edge I8 of the front member. The rib I1 is provided with a cut-out portion I9 adjacent side edge I Ii which leaves a cutting edge 20 which is in the plane of the bottom surface of the rib I1. Projecting upwardly from the ends of rib H are lugs 2I and 22 and projecting above lug 22 is a knife edge 23. It will be noted that the upper surface of lugs 2I and 22 determine an imaginary line which is substantially parallel to the upper edge 24 of front plate It and the cutting edge 23 of lug 22 projects upwardly a slight amount above such imaginary line as shown in Figure 4.

The front plate It is provided with apertures 25, 26 and 21 and a rectangular cut-out 28 is also provided through the front plate above the rib.

A removable bar 29 of substantially the same thickness as side member I I is provided with a semi-conical frustum 30 at each end thereof. The front and rear side bars I4 and I5 are provided with semi-conical frustum-shaped recesses 3|, 3! for cooperation with the frustum portions 36 of the bar 29 for accurately locating the removable bar .29 relative to said front and rear bars l5 and Id respectively. The removable bar 29 is provided with apertures 32, 33 which are used in locating a center of a drill in making the opening in the door for receiving the look. It will be noted that bar 29 is flush with the bars I4 and. 15.

Another form of the invention is shown in Figures 5 and 6 in which the body thereof may be made of a plastic type material which may be slightly deformed for removably holding the lock recess locating bar. The front ;'plate Ldfi thereof may be similar to front plate [Wand includes the longitudinal rib andtheprojecting lugs, but a blade element 3! made .of.steel or other material is secured to the front lug 21 by screws 42.

It will be understood that the blade 4! is recessed into the rib and lug'in an-obvious manner and a single blade may be used so that the lower edge d3 thereof serves the function of scribing edge as of the first amodification and the other upper edge id serves the-function of the other upper marking edge 230f -the first modification. Obviously a'separateblade may be used on the lug corresponding to'edge 2 3 if desired.

Another difference over the first modification is the means forsecuring the-removable bar 45 to the rear and'front side bars M'and I5. The ends of the removable'guidc bar 45 areprovided with V-shapednotches ,6, 45 at itsends. It will be noted that the distance between the apexes of the notches is substantiallyequal to the distance between the front and rear side bars 15' and M respectively. The front and rear side bars at their central locations are cut away to define a dihedralangleat l -tiwhich is substantially similar to the dihedral angle formed by the V-shaped notches d6, iEi in the ends of removable bar 45. Theremovablebar 45 may be removed-by a.slightzdeformation of the front and rear side bars l 1 5 and M'- to permit the -V-shaped notches -tolbecome disengaged from the dihedral angle portionof: the sidebars. ,The removable bar itis prov-ided with apertures 48 and 49 which are similar to apertures Hand .33 of the first formof the-invention.

In one use of the present.invention,:the tem plate is applied to'the edgef 'a doortin the manner shown in Fig. 21 with'the'ifront plateil fl in engagement withone-surface 'of:the..:door.=an'd the side member ll in engagement with a side edge of the door. The .templateis located-at the desired height of the .door lockdand the removable bar 29 is omitted. Aiscriberorknife edge is then moved along theinsideedges of bars [2, l3, Hi and I of the sidemember'thereby defining the location of the lockzplateinadoor of 1% inch thickness. TheremoVableJbar 229 is .then positioned inthe-template with thetemplate in the same location and the location .of aperture 32 is marked :on the door. edge. bysmeans of a pointed instrument such as a nail, compass point, or icepick. Then, while the templateis still held in the same location the location of apertures 25, 26 and .21 may besimilarly. indicated for determining the location of the door knob and attaching plate therefor. .Thetemplate is then removed and the necessary openings are drilled and other material removed by-a'chisel in a conventional manner, using the outlines for accurately determining the :edge-of the recess formed in the door. The advantage of the removable bar 29 should be apparent since by its removal, there is no interference With marking along the front and rear bars l5 and E4 the complete length thereof thereby keeping sharp edges. Also if a knife is used as a scriber there is no middle bar to engage the knife edge and consequently the knife does not become dull when used with the present invention.

The front andrearibars :[5 andl l are substantially of an inch thick in each direction and spaced apart one inch making the device specifically suited for a door of 1% inch thick- .ness andthe Width of the plate in a conventional door lock is one inch. However, some doors are 1 /4 inch in thickness and such doors may be marked with-the .present invention by using the back edge of rear bar Hi for marking of the edge plate of the lock. The template is then applied to the rear surface of the door and the back edge ofbar M then marks the front-edge ofthe plate ofthe door lock. The-bottom and topio'f the door lock plate maybe marked byusing-a knife or scriber ch mp and bottom-bars I Z'and 3. The location of the hole to be drilled may be determined by the location of aperture 330f bar 29 for the 1% inch door.

For marking the outline of a hinge, thefront surface of front plate IQ is positioned on the edge of a door at the hinge location and (if it is a four-inch hinge) lug 2! and 22 will engage a surface of a door to be adjacent thepintle of the hinge and the-outline of the hingecan be marked by a scriberpassing along the top edge 24 of the front plate, the side edge l e of the front plate and the rear edge 14R of thetemplate. The amount of material to be removed maybe indicated by drawing the markingiedge23 along the surface of the door leaving a small mark between the lines formed by .the scribing tool which has previously marked the topandnbottom boundaries of the hinge.

In the event that a 3 /2.inch..hinge.isbeing used,:the front plate Iilispositionedonthe edge of the door to receive the hinge and the bottom surface of .the rib H is made .-to:engage the surface of the door to be adjacent -.the pintle and the outline of the,hingeisfletermined-by passing. a scriber; knife or the like along-the side edge I6, bottom edge 58 and :a rear edgeil'fiRpf' the front plate. To marktheamount of material;to beremoved, the'templateuis moved .sothat the rib I'Lextends .at anangle-to-the front sur-' face of the door while the front surface of plate- 10 engages-the .edge of tthe door"lthereby bringing marking edge 20 into engagement with -th'e front surface .of the door andupon movement of the template from the line indicating one -en'd of'the. hinge to the line indioatingithe otheri-end of the hinge the mark made thereby shows the amountof material to be removed.

The openings 28 separated by bar-=28arprovided in the front plate. illisusefuliforilocatingadoor k.On.IGIatlVGIYLthlILidOOIS such as screen doors, storm doors or the like. In use the frontface of the iplate l B engages .the :edge of ithe door -..and lugs 2i and 23 engage. a :surface of the .door thereby locating the opening .28 at the (desired distance from the surface of the door-an'd the' outline .ofthe. doorlock .plate -is made by passing a knife, a scriber, or the like along theedges of the openings 28. An aperture-5282): serves -to locate a center for a drill forthe removal of material' to provide anopening for the doorlook.

The present invention. is also: useful "for mar-king the location of a keeper on the door lamb and this may be accomplished by positioning the side plate H against the door jamb and inthis use the projecting edge It of front plate I is positioned against the edge of the jamb. The side plate ll may be provided with marks M on the back thereof which may be used to mark the top and bottom edges of the keeper since the keeper is normally of less vertical dimension than the plate of the lock. The template may then be moved so that a top or bottom bar 12 or l3-may have one edge in registry with the mark previously made and the outline of the keeper may be accurately made with a knife, scriber, or thelike.

The invention is also useful for locating the conventional door stop strip and this maybe done by positioning the side member II in surface engagement with the jamb of the door with the front plate It] extending into the opening for the door in a position parallel to a closed door and the side edge I6 of the front plate engaging the room side of the jamb. The location of the adjacent surface of the door stop may be marked by using a pencil, scriber or other mark means at the back surface of the rear bar l4.

7 The modification of the invention shown in Figs. to 9 inclusive, may be made of a synthetic resin or other plastic material and the cutting blade 4| may be replaced when necessary and a new blade substituted therefor.

In Fig. 7 the removable bar 50 is similar to removable bar but the notch at one end is made with a cam-shaped portion 5! which materially assists the insertion and removal of the bar between the side bars I4" and I5 in this modification. There is a minimum of distortion of the side bars l4" and I5 and the bar may be inserted with the cam-shaped surface toward the inside or the outside and the outline of the door lock is maintained with an unbroken edge as described above.

Referring to Figs. 11 to 14, the main plate 52 is separated into two rectangular areas by a rib 53 approximately high and cutting edges 54 and 55 are provided at the bottom and top of the rib and such cutting edges are within the thickness of the rib so that they normally do not produce a mark on the edge of the door, but may make a mark when the rib 53 is positioned at an angle as described in the relation of cutter 20 to rib H in the first modification. The side plate 56 is provided with frusto-pyramidal recesses 57 on the front and back bars thereof and removable bar 58 is provided with frustopyramidal projections 59 at each end thereof for cooperation with the recesses for accurately positioning the bar 58 and locating the aperture 60 thereof in proper position for locating a door look. It will be apparent that the removable bar 58 is positioned so that the surfaces are flush with the surfaces of side plate 55 and the cooperation of bottom 51' of the frusto-conical recesses and the cooperation portion of the projections 59 serve as stops for properly locating the removable bar 58.

Referring to Fig. 11, the outline for a 4 inch hinge may be indicated by placing the rib 53 against a surface of the door and the upper portion BI of the front plate on the edge of the door so that the hinge outline may be marked around the periphery of the upper portion 6| in a manner described above. The amount of material to be removed may be marked by cutting edge 55 in a manner described with relation to. cutting edge 20. i I

Door lock for a 1%" door may be marked by placing the upper portion SI of the template in engagement with the edge of the door and the rib 53 in engagement with the surface of the door and the outline of the lock may be marked by forming a mark around the inner periphery of the recesses 62 and 53 which are separated by a bar 64 with an aperture 55 therethrough to indicate a drill location. The dimension of the upper section 5| from the rib to the upper edge is 1 and the apertures 62 and 63 with bar 66 define an opening 1" by 2 and such openings are spaced from the rib 53 and A from the upper edge. It will be noted that side plate 55 has its lower edge substantially flush with lower edge of front plate 52.

The lower section of front plate 52 is designed for marking a 3 inch hinge similar to that above.

It will be obvious to those skilled in thear-t that various changes may be made in the invention' Without departing from the spirit and scope thereof, and therefore the invention is not limited by that which is shown in the drawing and described in the specification, but only as indicated in the appended claims.
