Referring more inhdetail to :the? drawing, the present marking gauge embodies wan elongated-sheet .meta-l or other suitable abar 5hav-- 'ing a:straightrlongitudinal marking edge 6 and provided-witlrend portions '1 bent at right angles to' the mainibbdy portion to: form contacts zorfabutments toiengagez an; edgeiof a board or casing member to which-the board .abutments 7. are inithesameg' plane as c t-he straight edge, 6 of the-bar .5, :andsaid abut- ,ments 7 are, provided'with i'nturned' terminal flanges 9 so as to havemoreeffect-We and firm contact with: the :casing.

i The gange constructed-as thus -,fan described; is suitable for; severlalmnethods 1 of use,-examplesof-zw h'ich are: shown in Ei-gures- 5 and 6. --In'E;i-gu-re 5 the gangeis. illustrated in use for ma-rlri ng the linefor cutting a'base board 12 for-fitting itbetweenthe corner of a 13 of adoorcasingor'frame having azstrai'ght edge lLconti-nuecb to the floor of the room. In this use,-the endi0i the-base board r12w-hich is not shown is; temporarily iengaged'with' the preceding section oivbase boardnat a corner of the room. \vhiletheend of. the base-board 12 which-is shown isplaced against the lower end of the side casing member, 13as.illustrated. The bar 5 is previously placedacross the base board with the fixeduend 1 abutments projectingabeyond"saidbaseboardatthe 20 The marking bar is then laid across the upof a door frame isoften constructed at its opposite edges of the latter as shown, the bar 5 being of greater lengththan the width of the board 12 to permit this positioning of the gauge. The gauge is then forced toward the side casing member 13 until the edges 8 of the abutments 7 engage the adjacent straight edge 14 of the casing member 13. A suitable I marker, such as a pencil,'1nay then be drawn along the straight edge -6 to mark the exact line for cutting the .base board or sawing the end of the same off whereby it willbe accurately and closely fitted against the edge 14 of the side frame member 13.

V In Figure 6, the gauge is. shown inuse for marking a side member 15 of a window casing or frame, in which case the memberbr i board 15 is temporarily supported at its bot- 1 bottom edge of the frame member 17. The

tom upon the bottom'member 16 of the window frame, while its upper end is swung against the upper member 17 of said frame.

per end of the casing member 15 and pushed upwardly until the abutments 7 engage the pencil vor other marker is then drawn along the' straight edge 6, which is uppermost, so as to mark the exact line where'the frame mem-- ber 15 is'to be sawed off to accurately fit it between the frame members 16 and 17. p

I As shown in Figuree, the side member 1300 lower end with apart 18 whose outer edge projects or is offsetoutwardly of themain straight edge 14a of said side member 13a of the door frame or casing. As this member or part 18 is usually of considerably less height than the length of the marking bar 5, the

abutment 7 which is uppermost cannot be engaged with the adjacentedgeof the part or member 18 for properly plumbing the gauge so that a line may be properly marked on. the base board 1200 for accurately fittingthe latter against the adjacent outeredge of said memvide the same with a longitudinally adjustable her or part 18. In order to adapt the gauge for proper use under these conditions, I- proabutment or contact. As shown, this adjustable contact consists of an angular strip of metal providing an attaching arm 19 adapted to be flatly disposed against theinner face of the marking bar 5 transversely of the latter 7 and provided with a central opening 20 to receive a clamping bolt 21 which also passes slot 22preferably extends substantially from through a central longitudinal elongated slot 22 in the marking bar 5 and receives a clamping nut 23 by which the adjustable contact is fixed in any of its adjusted positions. The

Y end to'end of the marking bar 5 so that the adjustable contact may be employed in conjunction with eith'erend fixed contact or abutment 7 at any required distance from the same.

Theangular strip from which the adjust-able contact is formed also provides a contact arm or abutment member 24L projecting at right vention as claimed.

angles to the attaching arm 19in the-same direction as the abutments 7 and attached to the marking bar 5 so that its outer face isin the same plane with the straight edge 6. Any suitable means may be provided for maintaining the adjustable abutment againstrotation about the bolt 21 andwith the outerface of j the contact arm 24 parallel with the plane of the edge 6, such as outwardly projecting lugs 25 on the upper and lower edges of the at taching arm 19 adapted toslidably fit in the longitudinal slot 22 of themarking bar 5-.

V In the use of the invention as shown in Figure the gauge is positioned as shown and the upper fixed contact '7 is located above the top'of theframe part 18, the gauge maybe properly plumbed for utilizing the straight edge 6 in markingfa lineon the base board parallel with theouter edge of the frame part 18, whereby an, accurate fit will be had when the base board is sawed off I along this line marked thereon. I Obviously, the adjustable abutment maybe readily adjusted upon loosening the nut'23, whereupon the same may be secured in the desired adj usted position by again tightening said'nut.

The gauge constructed as above described is simple and durable in construction, economical to manufacture, and capable of being readily placed into practical and efficient use,

Minor changes may be made without de parting from the spirit and scope of the in What I claim as new is: 1 1. A marking gauge of the character de;

scribed, comprising a marking'barfhaving a straight longitudinal marking edge and a .pair of fixedprojecting end abutments, said marking bar being adapted to extend across. the board to bemarked and to'project beyond a the oppositeedges of said board to permit the" end abutments to engage the edgefof the :board or object to which thefirst mentioned board is to be fitted, anda further abutment carried by and adjustable longitudinally of said marking bar, said adjustable abutment being adjustable substantially from'rend to end of said marking bar for selective. cooperation with either one of said'fixed end ments, substantially as described.

abut- 2. A marking gauge for the frames of door casings and the like comprising a sheet metal marking bar 'having a straight longitudinal marln'ngedge and provided withend portions bent at right angles to the body' portion thereof to form end abutments, the marking edge 7 face of said contact arm of the adjustable abutment and the marking edge of said marking bar being in the same plane.

, 3. A marking gauge for the frames of door casings and the like comprising a sheet metal marking bar having a straight longitudinal marking edge and provided with end portions bent at right angles to the body portions thereof toform end abut1nents,'the marking edge of said bar and the adjacent side edges of said fixed end abutments being in the same plane, and a further abutment carried by and adjustable longitudinally of said marking bar, said adjustable abutment comprising an angular strip of metal having an attaching arm and a contact arm, said marking bar having a longitudinal elongated slot extending substantially from end to end thereof, a clamping bolt extending through the attaching arm of said adjustable abutment and the slot of the marking bar for slidably connecting said adjustable abutment to the latter, the outer face of said contact arm of the adjustable abutment and the marking edge of said marking bar being in the same plane, the attaching arm of said adjustable abutment having projecting lugs on the side edges thereof engaging in the longitudinal slot of said marking bar to prevent turning of said adjustable abutment about said clamping bolt. I

In testimony whereof I affix my signature.
