Specification of LettersPatent.

Patented J 111 14c, 1914.

Application filed February 2, 1914. Serial No. 815,972.

length of two sections of the rule, and having a normal position of repose which admits of the jointed sections being folded in usual manner; and has for another object the provision of an improved form of friction locking-device pivotally connected to the slidable gage and involving a wedge-like portion arranged to enter the space between the gage and the section of the rule, on which the gage slides, thereby to frictionally hold the gage in any position it may be set, said locking-device having an outwardly extended finger-engaging portion which is readily accessible, in order that the device may be easily and quickly operated to lock and unlock the gage; and has for another object to marker in a recess of a shape corresponding to the shape of the marker, which recess is formed in the end of one of the sections, said marker normally occupying a position in the recess in the plane of the section and being entirely housed thereby, and when turned on its pivot into a position at approximately right angles to said plane both of its ends will project to serve as marking points.

Figure 1 is a bottom plan of a jointed pocket rule having a gage and marker embodying this invention. Fig. 2 is a top plan of the same. Fig. 3 is a bottom plan of an end-portion of one of the sections with gage and marker thereon. Fig. 4: is a side view of the same. Fig. 5 is a bottom plan of the gage with locking-device shown in full lines. Fig. 6 is a longitudinal section of the same. Fig. 7 is an end view of the gage and transverse section of the rule on dotted line 7--7, Fig. 4:. Fig. 8 is an end view of one of the sectlons of the rule illustrating the marker in front view and in normal osition. Fig. 9 1s a simllar view, the mar or i sponding to :of the sections of the rule and the projections 15, 15, arranged to enter the rabbets '8 8. placed on 1 easily, the side-portions 13 and 14: terminatbeing turned on its pivot into vertical posltion for use. Fig. 10 is a detail view of one end of the joint-connection.

1, 2, 3, d represent four sections of an ordinary jointed pocketrule, 5, 6 and 7 representing the jointconnections or hinges. The gage here shown is arranged respectively in connections with sections 1 and 2, and said sections are formed at each side along the bottom with a rabbet 8, which rabbets extend throughout the entire length of each section or thereabout, and afford runways for the gage.

The gage comprlses a base 12 and a pair of side- portions 13, 14, with inwardly extended projections 15 at their extremities, the spaces between the side-portions correthe transverse sectional shape The gage thus constructed may be and slid along on the sections 'ing flush with the bottoms of the sections. The top of ;;it an inclined face 16, and the plate 17 is arranged on said base, at the inclined face :thereof, which is pivoted to the base at 18 Band is made wedge-shaped, and said plate arrange a pivoted double-ended joccupies a position between the side-pori tions 18 and it and projects beyond the base ;-at one end thereof, and its projecting porition is upturned to form a finger-engaging i portion 20. The pivot of the plate is located at one side of the center of the plate swinging in an outward directhe base is slabbed off to give to tion as represented by dotted lines Fig. 5. Movement of the plate on its pivot from the dotted to the full line position, shown in Fig. 5, acts to cause its wedge-shaped portion to enter the space between the base 12- and the surface of the section of the rule and by a wedging action thus produced will frictionally lock the gage in any position it may be set. Movement of said plate into the dotted line position Fig. 5 acts to free the gage from frictional engagement with the section, permitting it to be slid along. Both ends of the members of the hinge 5 or joint-connection are formed with grooves 25 extended diametrically across them, see Fig. 10, so that the sections 1 and 2 when moved into alinement as represented by full lines Fig. 10, the grooves in the ends of the hinges will be brought into alinement, and

thereby admitting continuous runways thereby provided between the sections 1 and 2, permitting the gage to be moved from one to the other section.

It is designed and intended that the gage shall have a normal position of repose, as represented in Fig. 1 wherein this position is selected as near the end of the section 1, and the side of the adjoining sectionet, at such place, is formed with a shallow recess 30, to receive .the side of the gage, so that the two sections 1 and 4 may be arranged in juxtaposition as usual when the sections are folded.

The end of. the section 1 and also if desired the end of the section 4, is provided with a marker, which, as here shown, consists of a small plate or blade 35 which is pivoted at 36 at a point intermediate its length to the end of the section, and has a marking point at each end as 37, 38, and the. end of the section to which it is pivoted is formed with a recess corresponding tothe shape of the plate which admits of the plate being housed in said recess, its outer face being flush with the end of the section, said marking-plate normally occupying a horizontal position as represented in Fig. 8,

when out of use, but may be turned on its pivot into vertical position, as represented in Fig. 9, to cause its marking points to project. 7

One of the many uses to which the device may be put is the following :the gage will be setat a predetermined point andthen the marker moved into marking position and then the rule will be slid along over the face of a board with the gage in engagementwith the edge thereof while the marker makes a line on the face at apredetermined distance from the edge. v

I claim 1. The jointed sectional rule herein described having one or moreof its sections formed with rabbets at each side, a gage consisting of a base with a pair of side-portions having inwardly extended projections attheir ends, the space between the sideportions corresponding ,to the transverse sectional shape of the section of the rule, whereby the gage may engage the section and slide along thereon, the top of the base of the gage having an inclined face, and a lo'cking-plate'pivoted to the top of the base having a wedge-shaped portion which cooperates with the inclinedface thereof and the adjoining face of the-rule to lock the gage in adjusted position, and also having a finger-engaging portion foroperating the locking-plate. I

2. The jointed sectional rule hereindescribed having two of its sections formed with rabbets at each side and its hinge formed-with grooves at its ends arranged to be brought into alinement with said rabbets thereby to form continuous runways, and a gage arranged to slide along on said sections having means to engage the runways and topass through the grooves in the hinge, and a locking-device associated with said gage for looking it in any position it may be set on both sections.

3. The jointed sectional rule herein described having a gage slidably arranged on the sections thereof, the end of one of the sections having a recess, and a pivoted double-ended marking-plate arranged in said recess, said recess corresponding in shape to the shape of the thereby to house thesame'when notiin use yet admit of both ends 1 of the marking plate projecting inopposite ways when said plate is turned on itspivot.
