Application February 5, 1951,

1 Claim. (Cl.,33-- 8 This invention pertains to new and useful improvements in aligning devices and has for its primary object a means for determining the error or deviation of intermediate portions of a masonry wall relative to the ends thereof.

An important object of this invention is to provide a wall aligning device having a means for leveling a course of a masonry wall, thereby preventing sag in the center of the wall.

Important features of this invention are to provide a sighting level simulating a telescope, a target having cross-hairs for alignment with the sighting level and intermediate longitudinally adjustable set of cross-hairs for alignment with the sighting and target levels.

These, together with various ancillary features and objects of the invention, which will later become apparent as the following description proceeds, are attained by the present invention, a preferred embodiment of which is illustrated, by way of example only, in the accompanying drawings, wherein:

Figure l is a front vertical view of a portion of a masonry wall and showing the application of the instant invention thereto;

Figure 2 is a top plan view of Figure 1;

Figure 3 is a fragmentary vertical view showing a section through the sighting block as taken along the plane of the section line 3-3 of Figure 2;

Figure 4 is a vertical sectional side view taken along the plane of the section line 4-4 of Figure 1;

Figure 5 is a vertical sectional side view taken along the plane of the section lines 5-5 of Figure l; and

Figure 6 is a vertical sectional side view taken along the plane of the section lines 6-6 of Figure 1.

Referring now to the accompanying drawings, wherein like numerals indicate similar parts throughout the various views, it will be evident that the numeral l0 denotes a portion of a masonry wall constructed in a conventional manner of a plurality of courses l2 of building block, brick or the like.

It is well known that the task of maintaining each brick in a single course at the same level or what amounts to the same thing, a plurality of levels or horizontal courses one above the other is indeed very arduous. Heretofore, as seen in the patent to W. H. Batchler, No. 2,505,- 935, the method of aligning intermediate blocks in a course was effected by tautly stretching a guide line between the ends of the course. This method could offer no assurance that a course was level, but merely that Serial No. 209,439

all points along the course were in the same line; even the latter could be erroneous if a slight amount of slack or sag occurred in the guide line.

To alleviate these disadvantages, the instant invention provides a pair of guide line holders or end blocks l4 and it having aguide line l5 stretched therebetween.

Block M has a substantially .L-shaped contour but one leg diverges inwardly, as at 20, for a purpose believed to be well-known but nevertheless to be explained in subsequent description. The transverse leg l8 also contains a medial slot 22 cutting through the central longitudinal cross section of the same. The leg 24 1s provided at its upper surface with a longitudinal recess 26 opening on both ends of the leg.

With the exception that its construction is reversed,the block [6 is identical, having a longitudinal leg 28 with a recess 39 and-an inwardly divergent transverse leg 32 with a slot 34. The reason for making one block the reverse of the other is clearly seen from Figures 1 and 2, where the blocks are illustrated in position on the masonry wall.

In either of the blocks, as M, there is slidably emplaced in the recess 26 a sighting means 36 comprising an elongated body 38 having open ends and being constructed of some suitable material. At one end of this body there is a window gauge 40 having, thereon a plurality of graduations as at 42. At this same end and disposed on the top side 24 of the body 38 is a spirit level 46 of a known and conventional construction. Separating the level Mi from the interior of the body is a glass pane and immediately below the same is a reflecting surface 50 mounted on an angular support 52.

At the opposite end of the body 38 is an eyepiece 5 1 of conventional nature and which, if desired, could assume the lens. It will now be evident that by looking into the eyepiece 54, it will be possible to see both the spirit level 46 and the graduated window gauge 40.

Since for the purpose of discussion, the block [4 has been chosen to receive the sighting means, the block 16 will be assumed to receive the target means 56. It should be understood that either block l4 or l6, could, if desired, receive either the target or sighting devices. At any rate, the target means 55 consists of an elongated solid block 58 slidably received in the recess 30 and having inscribed on one end 60 a set of crosshairs, as 62.

From the foregoing, it will be apparent that.

However, since numerous modifications be necessary to test the heighth of each block and changes will readily occur to those skilled in a course whereby the latter may be adjusted in the art after a consideration of the foregoing to provide a horizontal or level wall. With the specification and accompanying drawings, it is guide line l5 stretched tautly, the sighting block 5 not desired to limit the invention to the exact I4 is placed on the corner of the wall adjacent construction shown and described, for all suitany desired course to be tested.
