BRIQKLAY'ERS TOOL.

exact description of the invention, such as" will enable others skilled in the art to which. it appertains to make and use'the same, reference being had to the accompanying draw ings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in bricklayers tools, my object being to pro vide a device adapted when a wall is once started to make it comparatively easy to continue the wall in a horizontal plane;

Under ordinary circumstances it is quite difficult for the workman 'to keep the, wall level, and in order to do so it is necessary for him to fre uently employ a spirit-level He is also cal ed upon to. exercise considerable care with reference to the amount of mortar used. This,.together with other difficulties well known to bricklayers, makes it quite difficult to kee a wall level or so that its upper surface shall be in ahorizontal plane,

The object of: my improved device, as before stated, is to overcome this difficulty, and

.my construction willbe hereinafter explained in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof In the drawings, Figure lis a top plan view of a wall, showing my improved device in use or in position for use. Fig. 2 is a side elevation of the wall with thedevice in position. Fig. 3 is an enlarged section taken on the line 3 3, Fig. 1, viewed in the direction of the arrow. Fig. 4 is a side view of a slightly-modified form of .myimproved device. .Figsi5, 6, and 7 are detail views in perspective illustrating different forms of fingers employed in connection with the device.

bar 5 maybe designated A, B, and C, respectively. They are substantially the same in construction, but are' given different reference characters for convenience of descrip tion. Any two adjacent members are connected by. an auxiliary bar 8, which passes through openings formed in lugs 9 and 10 with which the respective members are provided. The bar 8 may be locked to either member by set-screws 12. By loosening one of these screws the two members of the bar may be separated, thus making the ,bar extensible to any desired degree. If desired,

the construction shown in Fig.4 may be employed,in which the bar5 is composed of a plurality of distinct members slidable upon a bar 8? and locked in any desired position of adjustment by set-screws12.

v To the upper or horizontal part 6 of the bar 5 is attached a number of fingers 1 3,

which, as shown in the drawings, occupy a position parallel to the member 6 of the bar and project beyond the member 7, so that thesefingers when, the device is in use are adapted to occupy a position above and in contact with the top layer of brick, while the layer-of brick immediately above is placed in position. the same thickness, it is evident that if the wall is once properly started that is to say, if the first layer of brick has itsupper surface in a horizontal plane-by the use i of my improved device the wall may be subsequently built to any desired height with each laver of brick in a horizontal plane. Y

Upon the barof my improved device are l mounted two leveling-tubes, (designated 14 As these fingers are of precisely I and 15, respectively.) The tube 14 is mounted on the bar in position to determine horizontal surfaces, while the tube 15 is mounted on one end of the bar or in position to determine plumb or. vertical surfaces.

. The fingers 13, as shown in the drawings,

are connected with the bar 5 by means of screws 16, whereby they are, readily attach-' able and detachable. The bar is provided with a considerable number-of extra threaded openings 17, whereby'the position of the fingers 13 may be changed on the bar at will in order to-m'aintain the fin'gersin the same relative position with bricks of varying length. Hence by virtue of this construction the. device is adapted for use in laying bricks of different sizes or lengths. It is well IIO known that different brick manufacturers make bricks of different sizes. Hence it is evident that the adjustment of the fingers for laying bricks of one length might not be suitable for laying bricks of different length.

Hence the necessity for a construction where-r by the position of the fingers may be regulated at will.

The finger 13 at the corner extremity of the device should be movable on its screws, so that it may be thrown outwardly, as shown at the left in Figs. 1 and 2, in order to bring it in position to roperly separate the corner bricks of the walI.

My improved device may also be provided with means for separating the adjacent vertical extremities of the different bricks in the same layer, thus determining the space between these extremities. drawings, a rod 18 may be mo unted upon each member of the bar 5. As shown in the drawings, the extremities of this rod are bent downwardly and inserted in openings formed in the extremities of the horizontal part 6 of the bar member. Fingers 19 are slidably mounted on the rod 18, which forms a holder therefor. These fingers 19 are provided with eyes through which the rod 18 passes. Hence the fingers are allowed to slide freely on the rod and may be used or not, as desired. If it is not desired to employ them, they may be thrown out of position so that they will not come in contact with the layers of brick. These fingers 19 are not shown in the correct position for use in Fig. 1, since they should be in alinement with the space separating the extremities of the bricks 20. The fingers are purposely shown out of their normal osition in order to facilitate the proper i lustration of other features. Their use, however, will be readily understood from the foregoing explanation.

The fingers 13 should be so shaped that their uppermost surface or surfaces are inclined so that they will readily pass through the mortar, allowing the corners of the fingers to engage the bricks both above and below. Theform of these angular fingers is well illustrated in Figs. 5, 6, and 7 of the drawings. The exact cross-sectional area is not important so long as the upper and lower surfaces are inclined. In Fig. 7 the triangular shape is used. In this event the finger has inclined upper surfaces exposed, while the lower surface occupies a horizontal position. It is believed preferable, however, to use either the form shown in Fig. 5 or Fig. 6, since in this case both upper and lower surfaces are inclined to the horizontal, thus allowing the upper and lower corners of the fingers to pass readily through the mortar and engage the upper and lower brick surfaces.

From the foregoing description the use and operation of my improved device will be readily understood. Assuming that the wall has been started, as shown in Figs. 1 and 2, my improved instrument is placed thereon in As shown in the r the position shown in the said views. In this event the leveling-tube 12 will quickly indicate whether the upper surface of the wall is in a horizontal position at the time when my improved device is first used. Assuming that this surface is horizontal, the fingers will project outwardly over the layer of bricks 20 and engage the upper surface of the said bricks. As the upper layer of bricks is placed in position mortar is applied to their lower surface and the bricks are pressed down until their lower surfaces come in contact with the upper corners of the fingers 13. In other words, the pins are caused to pass through the mortar applied to the under surfaces of the upper bricks. In this way the thickness of the pins determines the s )ace between the bricks or the space to be filied with mortar. It will be readily understood that by the use of this device the upper surface of the wall may be easily kept level or in a horizontal plane. When the device is placed in position, the part 7 of the horizontal bar engages the inner surface of the brick wall, while'the pins project outwardly over the top thereof. This arrangement is best illustrated in Fig. 3. The dotted lines in Fig. 1 indicate the end joints of the layer of bricks immediately belowthe top layer. Hence the fingers 19 are shown in the position they would be in if employed to separate the ends of the bricks of the layer next below.

The bar 5 is preferably provided with two projections 21, forming handles to facilitate the manipulation of the device. One of these handles is provided with an orifice 22, whereby the device may be hung up on a hook or nail when not in use.

In the form of construction shown in Fig. 6 the finger 13 is wider in one direction than the other, and it is provided with two

openings

13 and 13, extendin at right angles to each other. Hence this finger may be fastened to the bar by placing it in position to have the fastening screw passed. through either opening, thus adapting it for use with layers of brick separated by different thicknesses of mortar, thus making the single set of pins answer in both cases.

Having thus described my invention, what I claim is 1 Abricklayers tool, comprising a bar provided with fingers angular in cross section, the faces of the fingers being inclined to the horizontal so that when in use the corners of the fin ers or apices of their angles engage the waIls.
