CARPENTER S GAUGE.

Application filed September The object of this invention is to provide a gauge for use in fitting thresholds, moldings for door and window frames, and many like purposes.

A further object is to provide, in connection with an extension bar, formed of two or more slidable elements, a plurality of end pieces to be temporarily secured in the required adjusted position for determining the length of the piece to be cut and the type of cut to be made at each end.

A. still further object is to provide in such a device, a'plurality of sets of end pieces, for use under different conditions.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of elements described, illustrated and claimed, it being understood that modifica tions may be made within the scope of the claim without departing from the spirit of the invention.

In the drawings, which are a part of this application, Fig. 1 is a plan View of the device; Fig. 2 is a view showing one of the end pieces; Fig. 3 is a perspective View of a bar employed as an extension device, when necessary, between the longitudinal elements of Fig. 1, the studs of Fig. 3 then passing through the longitudinal slot for engagement by wing nuts. 1

I employ a flat bar of wood or metal, and of suitable length, the bar having secured thereto and extending perpendicularly thereof threaded studs or screws 11, 12, adapted to project through a longitudinal slot 1% in bar 15, and to be engaged by wing nuts 16, bearing on bar 15, or directly on washers 16 encircling the studs. One or more intermediate bars, such as shown in Figure 3 and designated 18 may be employed when a considerable distance is to be cov- 7, 1923. Serial NO. 661,495.

ered, as when measuring for long shelving and for thresholdsrof double doors. When bar 18 is so used, fixed threaded elements 11 and 12 pass through the apertures at the left hand end of this bar, and are to be engaged by wing nuts, and the threaded elements shown at the right hand end of bar 18 pass through longitudinal slots 14 and are to be engaged by wing nuts in the same manner as in the structure of Fig. 1.

For fitting a mitered head casing or molding, after the sides are in place, I use the end pieces '30, 31, each including a fiat bar with threaded stud 32 and end flange 33 extending at an angle of degrees with reference to the long side edges of the bar and projecting about one half of an inch at 34;, from the straight edge 35. This form saves much time in making the required cut, and an absolutely correct fit can be made.

t will be understood that the end pieces are moved outwardly into direct contact with each element against which the stock to be cut, is to fit, and the wing nuts are then tightened up, and the device used as a gauge and guide in marking the stock.

What I claim is r A device of the class described, comprising relatively adjustable bars, end pieces, and means for pivot-ally connecting the end pieces with the bars, said end pieces each comprising a flat plate and an end flange extending perpendicularly with reference to the surface of the plate and at an angle of approximately degrees with the lateral edge of the plate, and adapted to lie parallel with the edges of the bars when the end pieces are approximately perpendicular. to each other.

In testimony whereof I affix my signature.

JOHN HARRIS EDMONDSON.
