This invention aims to provide a novel tool adapted to be used inV finishing off the mortar joints of brick or other walls, the construction being such that the handle may be lengthened or shortened at will, when one tool is exchanged for another of a different length.

It is within the province ofthe disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts andk in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Figure 19 is an end elevation ofthe tool in use.

Referring to Figures 1, 2, 3, and 4, there is shown a tool which preferably is made of metal throughout. It includes a body 1 which is trough-shaped in cross section, the body being upwardly inclined at its ends, as shown at 2 in Figures 2 and 18, and being` tapered in width at its ends as shown at 3 in Figure 1, to facilitate the sliding move-A ment of the bodyl along the joint in the mortar. Cross pieces 4 are secured to the upper edge of the body 1. Standards 5 are attached to the cross pieces 4 and to the upper edge ofthe body 1, the standards being located parallel to each other and at right angles to the body. The upper ends of the standards are convexedly rounded as shown at 6, and the body 1 of the tool is convexedly v and transversely rounded, as appears at 7. There are elongated slots 8 in the standards 5. p

The handle for the tool is marked by the numeral 9 and is of loop shape, as Figure y1 will show, the handle 9 preferably being somewhat wider than the body 1 of lthe tool. The end portions of the handle are reduced in-width as shown at 10 so that there are openings 100 in the handle, near to the standards 5. The purpose of this construction will be explained hereinafter. The end portions of the tool are provided with end walls 11 which extend downwardly somewhat below the lower edge 12 of the handle 9. This appears clearly when Figure 2 is compared with Figure 4. The standards 5 on the body 1 of the tool and in contact with the inner surfaces of the end walls 11 of the handle 9. In the end walls 11, screws 14 are mounted, the screws passing through slots 18 in the standards 5, the construction being such that the handle 9 may be adjusted toward and awayjfrom the body 1. The heads of the screws 14 engage the inner surfaces of the standards 5 as indicated in Figures 1 and 2. Milled nuts k15 are threaded on the outer ends of the screws and bear against thev end wallsA 11 of the handle 9, tohold the handle and the bod'j7 1 of the tool assembled.

The screws 14 may bel loosened. and, then,

the handle 9 may be adjusted on the standards toward and away from the body 1, the screws moving in the slots 8. By tight-- ening the nuts 15, the handlef9 may be heldr in any position to which it may have been adjusted toward and away from the body 1 of the tool. By means of the handle 9, the body 1 of the tool may be moved alongl in a mortar joint between the bricks or the like, the mortar in thejoint willbe given the shape which is determined by the cross sectional contour of the body 1.

It is not necessarj7 that the body 1 be rounded transversely as shown at 7. ln Figures 6 and 5 of the drawingsparts hereinbefore described have been designated by numerals previously use'dwith the sufiix a. In' this' form ofthe invention, the body 1a is Vishaped in cross section, as shown. in Figure 6, andthe upper ends of the4 standa'rd's' are pointed, as shown at 6?; Figures 4"- a'nd 6 of the drawings make it. evident thatthe body of the tool, as to cross section, andthe standards, may be shaped in any desiredE way, depending upon the contour whichit .is desired thatl the mortar in the jonts'shall have. The body 1 is intende'd primarily for smoothing down the mortar inA the joint, and the standards 5, at their ends, are*` intended to plow out the mortar in' the joints, initially'. This, will be understood from Figures 18 and 19, wherein thetoolc is shown inverted and in plowing position, withthe roundedl endsY G of the standards 5 in" use. Here note that the longitudinal edges of thebody 1 slide upon the wall Wand act as a gage, whilst the rounded en'ds 6 of` the standard. are plowing out the mortar M, preliminary to the inversion of the tool from the position of Figure 18, and preliminary to the use of the body x1' as a smoother' for the joint that has been plowed out as aforesaid.

Referring to Figures 7, 8 and 91, the body of'the tool is markedv by the numeral' 16 and the base 17 of the body slants crosswise. Standards are marked by the numeral 18 and are provided` near to their upper ends with openings 79 for the receptionof the screws 14: shown in Figure 2. Guides 19 eX- tend. across the upper edges of they body 16 andn are secured thereto. The guides 19 have downwardly extended oit-set ends 2O which rideV along the surface ofthe brick work and act as gages' which determine the amount that' the base 17 of the vtool extends into the mortar joint. The ends of the body ofthe tool are upwardly inclined as shown at 21, so that thev body can ride smoothly along the mortar in the joints.

Referring'to Figures 10 and 11, theA body of the tool is in theform of a strip including an intermediate loop 22"andA end loops 23. The end loops 23 merge in to parallel standards 2&1., The base portions of the end loops are inclined so as to ride smoothlyl over the mortar in the joints, and the places where the loops 23 join the loops 23A are rounded as. at 25l to move` smoothly over the mortar. The standards have slots 26, so that the tool of Figure. 10, instead of being used alone, may ybe connected by the screws 14, for instance, to such a part as the body 1. As clearly shown in Figure 11, the end of vone of the standards 24 is olf-set laterally as shown at 27, the od-set standard being used to rake out mortar joints in angles in corners, whereas the straight standard is used to' rake out the mortar from bed and head joints in masonry.

AllV of the tools hereinbefore described may be supplied in adjusted lengths, and in. order tor work advantageously with tools of different lengths, recourse may ber had to thehandle shown in Figures 12 and 13, and, more especially, tothe handle shown in F igures 14 and 15.

En Figures 12 and 13, the handle includes an intermediate section 29 embodying side bars 30 and connections 31 joining the side bars. At the ends of the intermedi-ate section 29, the side bars 30 are formed into. out-1 wardly and laterally off-set fingers 32. An end section 33 is supplied` and is' ofy U shape, the end section 332 including side bars 3ft which are spaced apart transversely the same distance as the side bars 30 of the intermedi.- ate section 29. The side barsl 311 arereduced as at 35, to Jform openings 98.- It may be stated here that the openings 98, the openings l of Figure 2, the openings O5 of Figure 15; (hereinafter described) provide an exit for the loosened morta when the tool is used as indicated inr Fi yur- es 18 and 19, and because the handle, in the various forms of the invention, is loop-shaped, the mortar can fallI through it and is not smeared over the wall during the raking of the joint, as in Figures 18 and- 19. rlhe result is that the tool leaves a clean wall which is attractive in appearance,- the wall requiring' a minimum amount of cleaning off after the joints have been raked and smoothed y Reverting to the form of theinvention in Figures 12 and 13, and immediately under discussion, it may be stated that the side bars 34 are connected by a depending end wall 3G. This element has the same function as the'part 11 of Figure .fr and affords both a connection between the side bars of thehandle, and a good firm bearing on the standards 5 of Figure 2, for instance, when the nuts 15 are tightened up.

The innery ends of the arms 34 are receired between the fingers 32 and are held between the fingers by means of a securing device, such as a bolt 37. The shoulders `38A are formed in the fingers 32, andthe ends of the side bars 341; abut against' the shoulders, so that the end section 33 cannotswing on the bolt or securing device 37, the sections 29 and 33 being kept in alinement in this way, and a good rigid handle resulting.

The numeral 39 designates a U-shaped end section including side arms 40, oli-set fingers 41, shoulders 42, reduced end portions 43, and an end wall 44, as hereinbetore described. The side bars 30 of the intermedi- `ate section 29 abut against the shoulders 42 and are held thereagainst, and between the fingers 41, by a bolt or the like, marked by the numeral 45.

The intermediate section 29 may be dispensed with, and the sections 39 and 33 be used together, with one of the bolts 37 or 45. Likewise, one intermediate section k29 may be replaced by another ot a different length, the showing being the same, since the chain is in dimension, and in view of the fact that the intermediate section 29 is broken away in Figures 12 and 13. The construction is such that tools'of dil-ferent lengths may be accommodated, the body or main member 1 of the tcol, for instance, being` changed in length accordingly.

The handle shown in Figures 14 and 15 resembles the handle of Figures 12 and 13, in some particulars, and portions of the description relating to Figures 14 and 15 may be reduced to a mere catalogue of parts to avoid waste of words.

In Figures 14 and 15, the intermediate section is shown at 290 and includes side bars 300, joined by connections 301, and having outwardly oil-set fingers 302, the end section 303 including side bars 304, which are reduced at 305, to form openings 400, corresponding to the openings 98 of Figure 13, the depending end 306 corresponding to the part 36 of Figure 13. The shoulders in the side bars 300 are shown at 303. rlhe end section 309 has arms 310 corresponding to the parts 40, the lingers appearing at 311, and the shoulders at 312. The reduced end port-ion 313 forms an opening 320 that operates like the opening 98 of Figure 13, or the opening 100 of Figure 2. The end wall for the section 309 is marked by the numeral 314, and the part 315 corresponds to the element 36 of Figure 13, the part 315 having a hole 316 for the bolt 14 of Figure 2. rlhe modification in Figures 14 to 17, consists in providing the device with elements which replace the bolts 37, and 45, of Figure 12; and in this connection it will be observed that between the fingers 302 of each pair there are parts 321 that are left in the same plane with the side bars 304 of the end section 303 and are received in correspondingly shaped notches 322 that are formed in the ends of the side bars 304. Similarly, there are parts 323 between the fingers 311 of the end member 309, that are left in the same plane with the side bars 300,0f the section y290, and are adapted to be received in correspondingly shaped notches 324 formed in the ends of the side bars 300. The construction is such that when the bolts 14 of Figure 2 are engaged in the openings 316, of Figure 16, the sections 303, 290, and 309, will remain interengaged, without the use of such elements as the bolts 37 and 45 of Figure 12. It will be clear that the intermediate section 290 may be removed and be replaced by another section' of different length: moreover, the intermediate section 290 may be dispensed with, and the section 303 may be interengaged directly with the section 309, just as the section 33 of Figure 12 can be engaged directly with the section 39 of that figure, when the intermediate section 29 is dispensed with.

What is claimed is 1. In a device of the class described, a tool comprising a body provided with standards, a loop-shaped handle enclosing the standards, and means for holding the handle on the standards, t-he handle being cut away at its sides and at its ends to form clearance openings adjacent to the standards.

2. In a device of the class described, a tool comprising a body provided with standards, a loop-shaped handle assembled with the standards, the handle being wider than the standards to serve as a gage when the tool is inverted and when the ends of the standards are employed as mortar plows.

3. In a device of the class described, a tool comprising a body provided with standards, a handle adjustable on the standards toward and away from the body, means for holding the handle in adjusted positions on the standards, the handle comprising a plurality of parts, said parts having duplicated interengaged elements, whereby a part of the handle may be omitted, to bring about a shortening of the handle and an adaptation of the handle to a. mortar tool body.

4. In a device of the class described, a tool comprising a body provided with standards, a handle mounted on the standards, the handle comprising a plurality of members, and said members having duplicated interengaged elements whereby one member ol the handle may be omitted, to bring about a shortening of thek handle and an adaptation of the handle to a shorter tool body, said interengaging elements comprising oltset fingers on one member of the handle, another member of the handle being overlapped on the fingers, there being a part between said fingers, and said part being disposed in the same plane with said other member of the handle, said other member of the handle having a notch receiving said part.

In testimony that I claim the foregoing as my own, l have hereto aixed my signature.
