Application July 1, 1957, Serial No. 669,157

Claims. (Cl. 25-131) same time provide for the application of finishing material for the desired smooth straight finish.'

This invention or implement is economical in use and is technically satisfactory in the finishing of concrete walls.

Other objects andadvantages will be revealed in connection with the detailed description-of the accompanying drawings," which constitute a part of this application.

In the drawings:

Fig. l is a fragmentary-plan view'of the implement.

Fig.l 2 is a transverse section of the implement taken on the'line 2-2 of Fig. l. y

Fig. 3 is a fragmentary sectional view showing how each bolt is applied to the implement.

Fig. 4 is a sectional view taken `on the line 4-41of Fig. 3.

Fig. 5 is a sectional view showing an adjustable means.

Fig. 6 is a sectional view showing the adjustable means,llike that of Fig. 5, taken on the line 6 6 of Fig. 5. Fig. 7 is a sectionalV view taken on the line 7-7 of Fig. 6.

Fig. 8 is a vertical section taken substantially on lin 2 2 of Fig. 1, with the concrete applied. t

This implement comprises a frame having two angle irons Vor steel bars 1 and 2 connected together fixeclly by tubes 'which are weldedat their ends to the upright webs of the angle irons or steel bars.

The nuts 4 are welded to the upright webs of the steel bars 1 and 2 inside of the connecting tube ends.

Longitudinal channel .bars 5 and 6 are provided to engagethe uprights 7 of the concrete fonn. The screw threaded bolts 8 must be long enough to span the uprights .7 and also to pass through the channel bars and the webs as well as engage the nuts 4. ,The bolts may be seven or eight inches long more or less.

The implement may be eight feet long more or less and frame units are made respectively for an eight inch structions represent the preferred form or species.

In the modification shown in Figs. 5, 6 and 7 the connecting tubes 9 and 10 for the angle bars are telescopic, so that the angle bars may be adjustably spaced from each other to accommodate a wall thickness of eight inches, ten inches, twelve inches etc.

This modified unit can take the place of, at least three units of the preferred form or species.

Awall, ten inch wall, twelve inch wall etc.V These con- In the modified ferm Figs. s, 6 and 7 the feleseope tubes 9 and 10 must be provided with a series of suitably spaced transverse apertures 11 and 12 to receive removably transverse locking pins 13 and 14.

When a concrete wall reaches the finishing phase and its top portion 9 is still soft this implement is applied to the top of the concrete wall, so that the angle bars 1 and 2 rest on the top of the wall. The channel bars 5 and 6 engage the uprights 7 on the outside thereof and when the implement is in proper position the bolts '8 are tightened sufficiently to straighten the wall and make it conform to the straightness of the implement frame and at the same time the desired thickness.

Finishing concrete material can now be applied ybetween the bars 1 and 2 and finished'off with a trowel substantially on a common plane coplanar with the plane defined by the lower surface portions of the horizontal webs of the angle bars 1 and 2. i

When the concrete is sufficiently set or solidified then guage and force the wall to V.the implement can be removed and thereby leaving a` substantially perfect finish to the top portion of the wall.

Fig.. 8vis similar to Fig. 2 but is a more detailed disclosure, besides the concrete is shown. The sheeting of the form `is indicated at 7' and the concrete is indicated by 8'.

Detailed modifications may be resorted to as longas they come within the purview of the metes and bounds of the claims presented. For example, the tubes may have screw threaded caps thereon (not shown). Each cap could be provided vwith a screw threaded aperture to receive the bolts. Each cap could be .welded tothe upright web of the angle bars or channel bars if substituted for the angle bars. Of course, channel bars could be substituted for the angle bars 1 and 2.-

This implement is a finishing device for a softl con'- crete wall and is not a complete wall form. This implement s applied to the top of a soft concrete wall While the wall is still pliable. The members 5 and 6 engage the uprights 7 on both sides of the wall retained by the usual form. The lower webs of angle bars IlV and 2 engage the top of the wall as evenly as possible. Of course, the horizontal webs of bars 1 and 2 engage the .top ofthe walleas much as possible and the lower surface portion of the webs of bars 1 and 2 define the top surface por- Ytion of the wall and may be finished by applying as much additional cement or concrete as may be necessary to finish the top portion of the soft concrete Wall. Y

Of course, if the wall is not straight the bolts 8 can be tightened accordingly` to straighten the wall and its form, especially the uppermost portion thereof While After a portion of Vthesorft wallrhas been straightened the implement can be shifted longitudinally a suitable f distance to straighten and treat an additional portion of thewall, and thus repeat the operation until the wall is completely straightened and finished.

Having fully described my invention and the operation thereof, what I claim is: t

l. In a masonry implement comprising a long substantially rectangular frame having suitably spaced inner bars connected by a plurality of substantially uniformly spaced means, in combination with screw threaded nuts and screw threaded bolts in further combination with a pair of outer bars, each outer bar being located on the outside'of the inner bars, said nuts being located on the inside of said inner bars and secured thereto, said inner bars having apertures therein in alignment with Patented Mar. 29, 1950' l said threaded nuts, said outer bars also having apertures therein in alignment with the apertured portions of said inner bars, said inner bars being adapted to lie on the to-p of the soft wall between the uprights of the usual form, said apertured` portions of-said outer bars carrying.v said adjustable screw threaded bolts in alignment, respectively, with said nuts and the `apertured portions` of the inner bars and adjustably connected thereto, whereby,` said frame may be placed on top of `a soft concrete wall with said inner bars on the inside of the uprights of the usual form and said outer bars on the outside of the uprights, said bolts may be adjusted in order to. straighten the soft top portion of the wall and simultaneously guage the thickness of the soft wall.
