Application filed March 7,

This invention relates to brick or stone:

I masonry tools particularly to a combination tool for working recessed mortar joints to' produce the very decorativevetle'ct commonly known as raked courses. An'object of the invention is to provide a simple combination tool which may bemanipu'lated to perform substantially all the necessary operations in producin the raked course effect inanyor all partsbif the wall. I I Further objects and features of theinvention will become apparent from the follow ng description relating to a the accompanying. drawing wherein I have shown my preferred form.

Usually separatetools are used for removing the surplus mortar from betweenadjacent bricks or blocks to the required depth and for afterward packing and smoothing the mortar. This is because the scraping, as matter of fact, calls for more than a simple tool inorder to make speed in operating on the joints in the more open parts of the wall and in order 'to reach the mortar in recessed corners and the lil fQI example where two wall faces join at aright angle, the smooth-. ing or finishing operation also calls for more than a. simple tool because the corner recesses and the .cross? that is the vertical joints, calls for a dilierent sortof tool shape than may he usedto advantage on the relativelyflong line joints, that is'to say the horizontally extending joints. Consequently as far as I knowtherehas not been developed a satisfactory'tool for performing all the necessary operations in producing the raked course ef'tectprevious to myinvention.

In its preferred form my invention is embodied inatriangularly shaped tool, one slde member-of the triangle being formed curved at both ends like alhockey skate runner, thls' being the smoothing tool. Another side or leg of the triangle is recessed to bold. are movable'and longitudinally ustable scraping tool. The third side or-leg bracesthe other two and functions as a gauge to dete mine the depth or thescraping tool; Inci dentally, thistriangle shape, while not entirely essential, is especially convenient becauseof clearance in using the tool in abrupt corners as when two wall faces join at right angles. The side first mentioned, namely the smoothing tool portion, serves as a handle while scraping, and the recessed side serves as a handle while smoothing, these sides be. ing preferably substantially the same size in 1927.. seriaino. 173,274..

order that the workman is not inconvenienced by changing from one size of the handle toanother.

In the drawing Fig.1 is a perspc'otive'view of the complete tool; Fig. 2 is a side elevation thereof; Figs. 3' and 4C are diagrammatic views showing the use of the tool in the of different character and location. 1

Referring in detail t'o the drawing, 1 is the smoothing portion ofthe tool; 2 is the re joints cessed handle member containing the adjustleg andthe baseand its smoothing surface 1 is substantially planular for a convenient distance and the ends curve inwardly as at 1 and 1?. I is less abruptly curved than the end 1 and is narrower from about the point 1- to the very end. This narrow portion begins before i the curve in order that the whole curved end may be usedv fo-rfsmoothing between the ,nar'

It will be noted that the end 1 row joints as "where the bricks areplaced closer together than the standard mortar joint-i 1 The portion 1? is sharpened at its end as atil 'to serve as a scraper, reference being had to Fig. 3 wherein this narrow'p'ointed end is shown as gouging. out excess motar in a recessed corner of the'wall, a portion of the horizontal mortar bed being indicated at'M and'the bricks'in the course below this mortar bed. at B. The desirability ofthe three sided tool becomes apparent in this figure as it will be seen that considerable rotatingmovement' may be given the tool while in this gouging out position, in order'to quickly remove the necessary amount of mortar.

I The opposite end of the member 1 is also sharpened as at l, to serve as ascraper if desired. However, this sharpened end 1 will be very'little used because when digging the mortar out of corners it is-much easier to use the narrower end of the tool.

The leg 2 maybe secured in any'convenient manner to the leg 1 as a screw, and similar fastening means mav be provided between the side 3 and leg 1 as at 3, the side 3 curving outof the leg at 3, the portion 3 beingwidenedas shown at Fig. 1' to serve as gauge, the gauge being wide enough to span two adjacent bricks on each side of themor tar joint. The side 3 may be secured in any convenient manner to the leg 2 as by welding.

As shown in Fig. 9., the leg 2 is hollow for a considerable Xtent to receive doub'leended scraper 5 which is longitudinally ad ustable handle while-scraping, the other of saidpor; trons serving as the handle wh le smoothing, V and means on one of said portions pro ecting :later'ally from the tool to serve as a depth prising two mutually rigid diverging mem- -i and preferably made of tool steel or the like I .for hardness and to allow slight flexibility.

,The preferredform of scraper is a flat piece of metal bent up at its endsas'at 5.

Suitably secured in a boss 2 is a 'set screw 6 shown enlarged at its end and knurled.

The inner end of the screw bears againstan intermediate portion of the scraping tool and slightly bends it in suchmannerthat the tool is bourne against the bottom of the recess in the leg 2 at two points, one ateachside of the screw. 'lhis arrangement insures hold ing of the scraper rigidly in place.

It. will be seen that the scraper may projected as "far beyond the gauge portion 3 as it is desired to scrape back the mortar. In

other words, the scraper may be adjusted for any depth of joint recess. and this depth will be maintained. by reasono'l the gauge portion 3* bearing againsttlie bricks on either side of the joint, and preventing the tool from gouging any deeper.

In usingthe tool, all the line courses may be efiectively scraped out by long strokes of the scraper tool 5, as well as the vertical'or cross joints. The joints at corners and recesses maybe scraped out by the pointed end 1? as previously mentioned and shown, inFig.

termediate. portion of the leg 2, sm oothing 8, and during this scraping the operator holds the tool. by grasping ,thel ntermed atc portions of the leg 1. For smoothing the opera tor simply reverses the'tool, grasping the inout the'line joints by the member 1, the cross joints either by the portion. n01; 1, pref- 0It1bly'I",$.S illiisti'atedin Fig.4. v

, WhileIhave described the tool as comrisin f three, eneral parts formin the leps I h \J O ofatrianglc, it'is tojbeiunderstood thatthis substantially straight but rounded at one end to serve as a mortar smoothing tool, and an other portion being formed to receive and support a longitudinally adjustable scraping tool, thefirstmentioned portion serving as the gauge forthe tool.

2. A tool of the character described combers, one member having a planular mortar smoothing surface and having one end curving inwardly from said surface toward the tool, said other member being recessed a metal tool, adapted for scraping mortarand qad ustably seated in said recess, and'means carried by said other member for clamping the tool in adjusted position.

t. A tool of thecharacter described,'comadjacent legs with the outer surfaces thereof I curving inwardly, there ,beinga depth gauge and a relatively adjustable scraping toolprojecting beyond the gauge for scraping the surplus mortar previous to smoothing the joints with said first mentioned leg, said depth'gauge and scraping tool being positioned at the inter-sectioniof said adjacent legs... i

5.- A tool of the character described comprising an open triangularly shaped member, one leg of the triangular member projecting beyond the adjacent legs of the triangle, and curving inwardly towardsuch legs, one curved portion being narrow and pointed to serve as ajoiner and scraper for short or. narrowmortar joints, and aremov able and ad ustable scraping tool supported by one of said adjacent legs,:and means rigid with this leg for clamping the tool in dad's j usted position.

6. In a device triangle being adapted for smoothing a 1nor- 'tar joint, another 'leg-adjustably carrying scraping tool, and the third leg extending in abutting relat1onto the second leg andexof the character described, an open triangular member, oneleg'ofthe tending latera'llyof the s'crapingtool whereby it serves as a depth gauge for the tool, said tool being reversible and" there being gmeansf to clamp the tool n ad usted position.
