OPEN D'OUBLE PLUMB-RULE.

Specification of Letters Patent.

Patented March 20, 1906.

Application flied April 13, ifiilfii Serial No. 255.269.

To all whom it may concern:

Be it known that I, AARON VREELAND, a citizen of the United States, residing at Singac, county of Passaic, and Stat s? b ew Jersay, have invented certain new and useful 1m rovementsinOpen Double Plumb-Ruies ful y described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present invention relates to certain improvements in the plumb-rule shown in my Patent No. 761,430, granted May 31, 1904, and particularly to the form of' plumbrule in which the body of the rule has open in s in the sides for sighting the plumb-line.

he invention includes a construction for the plumb-rule by which the interior is ac cessible, and the side next to the brickwork for laying the brick and striking the joints, also means for protecting the edges of the rule from wear, for making theplumb-rule of skeleton construction, and for mounting project above the same and for bracing and steadying the rule when thus mounted.

The invention also includes a box plum brule having marks also the edge next the wall indicating the love s of the successive courses and having a wire wrap ed around the rule at such marks to show t 1e levels of the successive courses.

The invention also includes a movable stand for holding a guideline in conjunction with the plumbq-ule. i

In the drawin Figure 1 is a perspective view of a box unibrule mounted upon a wall and rovicibd with all of the improve ments. ig. 2 is a cross-section on iine 2 2 in Fig. 1. Fig. 3 is an elevation of the lower end of the plumb-rule shown in Fig. l, and Fig. 4 is a diagram showin the cornerof two vertical walls with plum rules applied to the inner and outer corners of the same. Fig. 5 shows the stand forthe guide-line.

Figs. 1 2, and 3 show a box plumb-rule with side casin sa,connected at each of their opposite endsiy two crosslates b band intermediate to their ends y narrow braces or cross-bars c at the outer side of the box, the inner sides of the cross-bars being connected by brace-rods d to the inner edges of the casings. The inner edges of the casings, as shown in Fig. 2, are eveled upon the inner side, and strips of hoop-iron e are secured the plumb-rule upon a wall to upon theouter sides of the casin s and form the edges in.c0ntact with the was Slots g are formed in the casings to sight the plumbline, and a plumb-lino h is hung from the top of the box upon a line with the inner sides of the slots, as is cioarly shown in Fig. 2. The upper sides of the cross-bars c are formed with central lines o to coincide with the plumbline when the plumb -rule is set vertically, and the. cross plate 5 at the bottom is formed with cross-marks e to indicate an approximate setting of the plumbbob i, and the exact setting of the plumb-rule is secured by finally sighting the line it across the inner edges of the slots 9 and adjusting the marks c to coincide with the line.

The lumb-rule may be made twelve feet in heig it and supported next to the courses already laid by driving a wedge or platei (see Fig. 1) or large nails in into one of the coursejoints and setting the plumb-rule upon the same. A clamp-bar l is shown at tsched to the base of the plumbrule in Fig. 3 by bolts m and set-screws nprojected through nuts n in the base to inch the plates against the clamp-bar. en the base of the plumb-mic is thus secured, the top may be braced, as shown in Figs. 1 and 4, by wooden braces p, extended'fioin the top of the plumb rule to difierent points upon ioists o, secured upon the inner or outer sides of the wall.

The joists are shown in Fig. t upon the inner side of the wall and the braces ivoted upon the to i of the piumbu'ule by olts g 'oists. The

and extended orizont ly to the before the lmnb-rule is seglperfecti'y vertica races are secur to the ioists.

a brace 12 is shown in one leaf of a hinge r, the other leaf of which is ivotetl upon the side casing of the plumbru e by a bolt 8, so that the race is alwa s associated with the lamb-rule and maye turned longitudinal y of the same when packed for transportation.

Fig. 2 shows that, owing form of the box plumb-rule, the box of the rule is wholly open upon the inner and outer sidea'so that a workman standing inside the wall can gain access to all the outer goints of the brickswhen laying one course a to the skeleton ove the other, whiie'a workman standing upon a platform outside of the wall can operate through the plumb-rule itself to lay the Fig.1 attached to courses of bricks and to strike the the courses.

To fit the box plumb-rule for use upon the inner corner of a wall, the box is made with two side casings a, each having slots 9, the inner ed es of which serve to sight the plumbline, thc iocation of which is indicated by the cross a". In Fig. 1 a scale of marks t is shown upon the edge of the easing next to the wall, the marks being spaced to correspond with the upper corners of the bricks in the successive courses, the initial mark at t being set even with the course last laid and the successive marks thus indicating the proper level for the superposed courses.

In Fig. 1 a wire is shown wrapped around the plumb-rule and stretched in successive lines a between the casings a upon the inner side of the plumb-rule coincident with the scale-marks t, and when the plumb-rule is set vertical such lines extend perfectly level and guide the laying of the Fcourses between the casings. The casings o the box plumbrule may be made twenty, thirty, or forty inches apart, as may be desired, and even made wider to fill the entire space upon a wall between buttresses, so as to plumb the buttresses at the same time that the wires a guide the bricklayer in leveling the successive courses.

Figs. 4 and 5 show a portable guide-line stand having uprights 1) attached to a base y and set u on the wall at such a distance from the p umb-rule that guide-lines may be drawn from one to the other and a section of the wall thus built up as far as the bricklayer can reach. The uprights -v of the stand are shown braced to the base 1 by bars at and the base loaded with a pile of bricks 2 to hold it firmly in position. with guide marks or holes w, coincir ent with the guide-marks t upon the plumb-rule, and a nail inserted successively in such holes serves to set a uide-line level with the corres onding mari upon the plumb-rule.

uide-lines u are shown in Fig. 1 extended from the side of the plumb-rule, and two of the guide-lines are shown in Fig. 5 fixed to nails '0 upon the u ri hts at a suitable .distance above the wa 1 courses. The guide-line shown in Fig. 5 can be removed, if desired, when one course of brick has been laid between the plumb-rule and the stand and transferred to the next space above for laying the succeeding course, and one guide-line or a series of uide-lines may thus be kept in use between t 1e lumbrule and the stand until the section 0 wall is completed, when the stand would be transferred to a more remote point and lines stretched from the stand to the joints of the courses in the section last finished.

B making the guide-line stand with a base 3 a a ted to rest directly upon the top of the wall, t we stand may be set in any desired pojoinfs of sition and secured temporarily in such The bars 12 are provided to lay the succeeding P vesition by loading the base, as with the pi lc of bricks z.

Having thus set forth the nature of the invention, what is claimed herein is l. A box plumb-rule having edges to contact with the brickwork and open upon the side next the brickwork, to permit the laying of bricks and striking the joints adjacent to l the rule.
