Application fueanay 2s, 191e.l serial No. 299,958.-

To all whom t may concern.' Y

Be it known that I, JOHANNES U. `:Rosas- HoLM, a citizen of Finland, and residing at New York, in the county of Bronx, and State of New York, have invented certain new and useful Improvements in Combination-Tools, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same. f

The object of this invention is to provide an improved tool of the class specified which will serve as a square, as an ordinary rule, as aplumb device, as a level device and as a bevel or miter gage device; and with this and other objects in view the inventionconsists in a tool of the class specified, constructed as hereinafter described and claimed.

vThe invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designatedv by suitable reference characters in each of the views, and in which 5- Figure 1 is a side view of my improved combination tool and showing the parts in position foruse as a square;

Fig. 2 a partial section on the line 2 2 ofk Fig. 1 and on an enlargedscale; .l

Fig. 3 a partial section on the line 3+?) of Fig. 2 and on an enlarged scale; and

Fig. 4 an end View of the toolV looking in the direction of the arrow 4, of Fig. 1. In the practice of my invention, I provide an elongated body portion a which may be of any desired length, and which is of I-beam form and comprises la central web portion a2 having side members a3;

The body portion is saw cut longitudinally at one end thereof to form a longitudinal slot a4, which communicates at one end with a rectangular recess a5, which is similarly formed, and the slot a4 extends longitudinally of the body portion over half of the length thereof, and this makes the parts a6 of the body portion formed by the slot a4 slightly elastic.

I also provide an ordinary rule b having an approximately rectangular head b2 which is pivoted in the recess a5 by means of a bolt c provided at one end with a thumb nut 02 and the rule o is adapted to be turned at right angles to the body of the tool as shown in Figs. 1 and 2, or to be folded into the slot a4 as indicated in dotted lines in Fig. 3.

Specification of Letters Patent. Y

Patented 1160.9, 1919.

The head b2 of the rule Z) isprovided with a projecting nose b3 andvr formed on the web portion of the body of the tool at one side Y thereof, and adjacent to the pivoted head of the rule b is a longitudinal shoulder a7 between which and the ladjacent side'c of the body portion of the tool'is p-ivoted a lever ci, the end of which adjacent to the head b2 of the rule b -is provided with Aa nose d2 adapted to be passed through an aperture a8 in thev web portion a2 of the body of the tool.

One side of the central web portion of the body of the tool is cut out to form a longitudinal aperture a in saidweb portion in which the lever Z is pivoted and in which it operates', and the inner end of said lever is provided with a knob or head cl3' and pressure applied to the outer end lof said lever Y will force it into the position shown in Fig. 2 in which the rule?) is locked in its operative position, or that shown in Figs. l and 2', while pressure on the knob cl3 will force said lever, or the operative end thereof, outwardly and allow the rule b to be folded into the body portion of the tool as indicated in dotted .lines in Fig. 3.` i j f Formed in the central part of the web portion of the body of thetool isa longitudinal aperture e on the opposite sides of which are placed spirit level tubes @2 and formed in the web portion of the body of the tool at the opposite ends of the aperture c are rectangularv apertures f, and in the aperture f farthest from the pivoted end of the rule Z) is secured a'` spring pawl 'g having a nose piece g2 adaptedl to engage or enter a recess b4 in the free end of the rule Z ,"asV indicated in Figs. 1 and 3, and this pawl tion so that it can be vengagedy by the lhand or fingers of the operator.

In the end portion of the body of the tool opposite thefpivoted rule b is another transverse aperture ,7i in which are placed and se cured to the transverse spirit level tubes z', and the operation of the device will be readily understood from the foregoing description when takenV in connection with the accompanying drawing and the following statement thereof.

The spirit level tubes c2 arranged longitudinally of the tool, or the body portion thereof, enable the device to be used as a spirit level with either side up, and the spirit level tubes c' arranged transversely of the tool, or the body portion thereof, enable the device to be used as a plumb with either end up; and by reason of the connection ofthe rule l) With the body portion said rule may be turned at right angles to said body portion as shown in Figs. 1 and 2 Where it may be locked by the lever (l, or it may be turned at any angle from Zero to 90o and locked in such position by the bolt c and thumb nut c2, and this enables the device to be used as a miter or bevel. gage, and by means of the construction shown and described, I provide a tool of the class specified which is simple in construction and operation and which may be easily. and conveniently used for all the purpose specified, and which Will not easily get out of order, or be broken or otherwise injured; and while I have shown details of construction Which I prefer in carrying my invention into effect. it will be understood that the said invention is not limited to the eXactdetails of construction herein shown and described, and changes therein and modifications thereof may be made, Within the scope of the appended claims, Without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, What I claim as new and desire to secure by Letters Patent, is l l. A tool of the class described compris ing an oblong body portion provided centrally thereof With an oblong aperture in which is secured two spirit level tubesl and in one edge portion thereof With a transverse aperture in which is secured two spirit level tubes, said body portion being also provided With a rule which is pivoted in one end portion thereof, and in one side edge portionvthereof With a longitudinal slot into which said rule is adapted to fold, means for locking said rule in its extended position, and means for locking said rule in its closed position.

2. A tool of the class described comprising a body portion composed of separate parts, said body portion being provided in one end thereof With a rectangular recess and in the other end portion thereof with a transverse aperture and in one side edge portion thereof with a longitudinal slot which communicates With said recess and with said aperture, a rule having'` a head pivoted in said rectangular recess and adapted to fold into said slot and into Vsaid aperture, and a lock device in said aperture for securing said rule in its closed position.

3. A tool of the class described comprising a body provided in one 'end thereof With a rectangular recess and in theopposite end portion with a transverse aperture, said body beingalso provided in one side edge portion thereof with a longitudinal slot which communicates with said recess andv with .said aperture, a rule having an approximately .rectangular head which is piv oted in said recess, said rule being adapted to fold into said slot and into said aperture, the head of the rule being provided With a projecting nose and a lever pivoted in the body and adapted'tooperate in connection with said nose to lock said rule in an open position, said aperture being also provided with a lock device for securing said rule in a closed position.

In testimony that I claim the foregoing as my inventionl I have signed my naine, 1nV
