Application' led J' une y18, 1917. Serial No. 175,281.
broadly,=to provide af, tool which will be convenient in useforia varietyV of purposes-and will consist of 'fewfandsimple parts so that it may z be economically manufactured.
One of thespeciic objects of the invention graduatedframe which may be used asa straight edge, or measuring stick, or asa level. Another-object isto provide a tool which may' be used as an ordinary carpenters i square, f and another `specific obj ect lis toprovifde such a construction that acute or obtuse angles may be readily determined. The invention alsohas Areference tothe provision of a graduated slide for measuring' vobjects which have -a,-.greater` length than the length` Yof the frame, and which will cooperate ,withi otherl parts lmaintaining a .graduated blade in yfixed, adjusted relation with the frame when the-partsare arranged tor 4a. carpenters square, and has -reference to `certain inea-ns for makingy adjustments of the level.
With the foregoing-objects in view `and .othersto beiinentioned hereinafter, the invention presents -a,novell construction, combination Aand arrangementvoffparts as described herein and claimed, land. as illus-V tnatedf in thefaccompanying drawing, wher .fin,- e

F.ig.18 isa viewI showing the, reverse side ofthedevice, j Fig.-9 isabrokenaway detail -.showing the parts arranged for .use ywhen determining angles.V Fig. 10'is a sectional view through the housing-ring, the section 'being taken longitudinally through a part of the frame-on line 10j-10 of Fig. 8. -F ig.
11 -isasectional view-oniline -11-11 of Fig. S, to show a means for locking the graduated blade when it is disposedat right angles tothe frame.
Referring now to the drawing, I provide anfattenuated, -rectangular i graduated frame l, Yconsistingin part, of the pair of metallic strips 2, uniform in lengt-lr and of the saine width, eachbeing provided with outwardly projecting flanges at its edges,.indicated at c and b, best shown in Figs. 5 and 6. At 3k Vis indicated al graduated cap having the same length as thestrips, said cap being provided with angular flanges c near its edges, vsaid anges c being disposed outwardly of the flanges a and rigidly secured thereto by-any suitable means, and thereby providingfa framesubstantially of I-shape in cross-section having a channel t opening upon its ends and one longitudinal edge. Numeral 5 indicates a graduated slide simi-L lar to the cap 3, its angular flanges Z- being mounted to permit longitudinal movements on the anges Z), said slide lia-ving thevsame length as the strips 2.
The strips 2 are provided, adjacent to one- Iof their ends with circular openings 6 in -which is inserted a housing-ring7 provided with a circular flange 8 which is disposed between the side strips 2. Numerous apertures 9 are formed in thefflange 8,these being disposed in aiiiarc, substantially of 180 degrees, the ends Aof ythering 7 bearing suitable indices or characters 10, corresponding to the vapertures 9. Numeral 11 indicates a suitable holder for thecconventional transparent leveling bulb 12',V said holder Abeing provided with a segmental ,base-strip 13 adapted to be disposed -within the ring 7 and being seouredthereto-by a set-screw 14; and'it will be understood that the ring 7 may be manually rotated to 'dispose-the bulb at' any desired angle with reference to the longitudinal axis of the frame. -Means are-provided for'maintaining the bulb at any selected angle, consisting of the spring 15 Iprovided with a tapered pin 16, said spring being mounted on the side of one of ,the strips.2- its pin being adapted to engage in anaperture 9 .of the flange 8 after an, adjustment of the jlevel has been made, said pin entering an aperture L9 aft-er traversing an aperture 18 formed in a strip 2, a screw 19 .and wingnut 20 being used for this` purpose.
Numeral 21 indicates a graduated blade,
bearing on its respective sides any suitable lines or marks to indicate acute or obtuse angles or for determining lineal measurements, as best shown in Figs. 8 and9. By.
-provided,'near one of their ends, with apertures e (Fig. 11). Numeral 25 indicates a spring-latch which is secured at one of its ends upon the side of a strip 2, its lug 26, at its opposite end, preferably being angular in cross-section.
The slide 5 isy provided on one of its sides, adjacent to its recess 23, with an ear or plate 27 having an aperture 28 formed therein, to operate as a catch-member, said aperture being angular in plan, for receiving therein the lug 26 of the springdatch.
By means of .thescrew 29 which is disposed in yapertures e and threaded in the wing-nut 30, the spring-latch 25 may be vpressed downwardly so that its lug 26 may enter the aperture 28, and also may enter a corresponding aperture 31 formed in a strip 2, which revents any longitudinaly movement oft e graduated slide 5 with reference to the strips2.
It will be seen that any swinging move ment of the blade 21 from a right angle to the frame will be prevented after the lug of the latch 25 enters the aperture 28.l since a longitudinal movement of the slide will thenbe prevented by the 4lug 26, and one of the edges of the blade 21 will be disposed in engagement with the end walls of the recesses 22 and 23, a third bearingfor the blade 21 being provided by the screw 29 engaging in one end of the slot 24 of said blade.
When it is desired to use the device for the measurement of angles, the wing-nut 30 is rotated to permit the lug 26 to move outwardly from the aperture 28 of the plate 27 of the slide 5, and from the aperturey 31 of the strip 2. The slide is then moved longitudinally and outwardly of the frame to permit the blade 21 to be disposed transversely of the frame and at any desired angle indicated by the lines 32, best shown in Fig. 9, and, lasis obvious, either acute or obtuse angles may be readily determined by use of the device. It will be noted that when the slide 5 has been moved outwardly,
kthe blade 21 -may bear upon and be sup- W'hen it is desired to use the device as a leveling implement, the blade 21 is housed in that part of the chamber l between the leveling device and one end ofthe frame. Numeral 33 indicates a slot which is formed in the segmental base-strip 13, to permit adjustments to be made for the bulb-,holder 11.
It will `be understood that in some instances the graduatedblade 21 maybe used in conjunction with the level in determining angles, the level indicating whether or not the blade is disposed horizontally when the frame is disposed at a required angle,
The device as described provides three scale-strips, since, in addition to members 1 and 21, the member 5, when its plate 27 has been released, maybe extended by sliding it on the iianges b. It will be appreciated that the device may be manufactured economicallysince the parts are few and of simple construction. By referring toFig.
angles kto the graduated frame, and whenA the latch is pressed inwardly, its projection 28 will enter this slot, and aid in maintain-` ing said blade and frame at right-angles with reference to each other.y
I claim:
1. In devices for the purpose described, a rectangular, attenuated, graduated frame including a pairof apertured side-strips, a graduated'cap having a recess opening on one of its ends and rigidlyT mounted on'the side-strips at one of their longitudinal edges, a rgraduated slide having a krecess opening on one of lits ends and engaging the longitudinal. edges of the side-strips` opposite `to said cap, a graduated bladeprovided with a slot midway between its longitudinal edges'and adapted to be disposed in the recess of the slide intermediate the side-strips, a pivot-pin traversing the apertures of the side-strips and the slot of said nally of the frame to permit the blade to be disposed at selected langles with referv ence to said frame, and a latch on the pivotpin in engagement with the slide" for maintaining the blade and slideV in stationary relation with the frame.'
