This invention aims to'provide anovel device whereby a builder may erect means for determining the corners of a building, and .whereby he may have atj his command va means by wh'ichhe can bef assured that the.. vcourses of brick, tile or the like, are arranged ln the drawings 1,- Y Figure 1` shows in elevation, adevice con. structed in accordance with the invention;

In carrying out the invention, there are provided four posts, but since the posts are of like construction, the description will prof? ceed in the singular number as tothe-posts.

` Each post 1, then, may bemade of any suitable material. Each post 1 is calibrated longitudinally, as shown at 2, the unitsl of calibration being large. The post 1 has an outstanding upper arm 3 and an outstanding lower arm 4. There is an opening 5 in the arm 3, and the arm 4 is provided with an` 8 opening 6.

yThe openings

5 and 6 are the same distance from the longitudinal center of the post 1. The numeral 7 marks a plumbline. The upper end of the plumbline 7 is mounted in the opening 5 of the arm3. A

Vbob 8 is mountedfon the lower end ofthe plumbline 7. The bob 8 4cooperates 4with the opening 6 in the lower arm 4 to show when the post 1 is vertically disposed. The post 1 may be provided with a level 9, whereby the post may be used, `if desired, to lay horizontals.

The numeral l0 marks a' foot, having upstanding ears 11, between which theflowerf end of the post 1 is disposed. A pivot element 12, such as avbolt, is mounted in the ears 11 and extends through an opening 14 formed in the post 1 near to the lower end of thefpost.: Azpiece of board, marked by the numeral 15, islmounted on the groundl, or on any jpart of the building `which may be accessiblei By ineansof'securing elements 17,.the foot 10v is secured tothe member 15. rider 18, in the form ofa U-shaped mem- 1 ber, -is mounted on the post 1 for'adjustment f longitudinally ofthe post. Oppositely disposed clampsc'rews 19'and 2O are threaded into the armsof therider 18 and areadapted to-bind upon or extend intothe post `1. `A third clamp screw 21is mounted :inthe'end 1 Vof the rider18 and is disposed at rightangles totheV clamp screws 19 and. 20'. .Braces .22 and 23 areiprovided, andare located .at right angles to each other.` The brace 23A is held .onfthe rider 18v by the clamp-:screw 211,and

the clampscrew 19 holds .the brace,22;on the rider. For the 'sake of'adjustment, the upper ends of the

braces

22 and 23 are supplied withelongat'ed slots 24 in which the bolts 19` and 21, respectively, are mounted. At their lowjer ends,v the

inclined braces

22 and 23 are provided withenlarged feet 25 having open,-

ings 26 adaptedto receive stakes 27 or other fastening devices, whereby the lfeet may be connected to the ground 16 ortolanything else that is available. .Owing tothe `fact that thebraces 22 andv 23 have `.slots 24, and

because theanchorage at 27 is not absolutely immovable, and because the post 1 has some.V movement on thebolt 12, the post 1 may be swungA around in any 4 desired direction, f enough to plumb it, byfmeans of the line 7 v and the bob 8, andfwhen the post 1 is in a truly vertical position, as nearly, as the same can 'bedetermined withinpractical limits, the

screws

21 and 1 9 aref'tightened up, and, then, thebraees A22 and 23will hold the post 21 in a verticalk position at ,the corner 'oi the'wall- 45 which is to be built.

A loop-shapedslide 28 is mounted for ad-V justment on the post 1, longitudinally of the posts;V The slide 28h`as an Voi-set socket 29 in which is mounted a rule 30, the calibrations oftherule being iiner than the calibrations 2 of the post 1. A set screw` 31 is threaded into the socket 29 of the slide 28 `and serves to press the rrule 30 againstthe post 1 for the double purpose of holding the ice rule 30 in any position to which it may have been adjusted longitudinally, and of holding the socket 29 in any position to which it may have been adjusted lengthwise of the post l. The slide 2S has a fastening device 32, such as a hook, to which may be connected one end of a line 33, shown in Fig ure 3, the line 33 being extended horizontally to another slide 28 on a post corresponding to the post l. The position of the slides 28, considered vertically, may be regulated approximately by means of the large calibra tions 2 on the post 1, and, then, the positions of the slides 28 can be determined more accurately by using the rules 30, with small calibrations, in connectionv with the marks shown at 2in` a way which will be obvious when Figure l of: the drawingsis noted.

It will be obviousthat the device forming the subject matter of this application may be used not Onlytokeep the 'corner ofthe wally vertical, but it may be used, also, to keep all'of the bricks, tiles, or other building elements in a horizontalv position in any particularcourse, the slides 28 being moved upwardly and being re-set, as one course after another is laid;

l/Vhat is claimed is 1. In a device of the class described, a substantially vertical post, a plumbing device carried by the post, a foot, means for connecting therlower end 0In the post pivotallyA with the foot, a rider adjustable on the post longitudinally` thereof, means for holding the rider inadjusted positionslongitudinally of the post, braces inclined withl respect to thepost, meansfor connecting the upper ends of the bracesadjustably with the rider to permit plumbing of the post, and means anchoring the lower ends of the braces.

2. In a device of the class described, a substantially vertical post, means for mount# ing the post at its lower end for swinging movement, means carried by the post for plumbing the post, adjustable means for holding the post in plumb position, a slide adjustable longitudinally ofv the post and provided with means for` holding a horizontal line, a rule within the slide and adjustable longitudinally in the slideand a clamping device carried by the slide and engaging the rule to press the rule against the post and to hold both the rule and the slide in adjusted positions, the post having calibrations wherewit-h the rule cooperates.

In testimony that I claim the foregoing as my own, I have hereto aliXed my` signature.
