SCAFFOLD BRACKET.

Application filed February 13, 1929. Serial No. 389,636.

This invention relates to brackets especially adapted for supporting a scaffold during the construction of a building, an object being to provide a bracket which may beused as a scaffold support when applying sheathing, sheathing paper and shingles, or brick and other veneer to the outside of a building.

Another object of the invention is the provision of a bracket of the above character which may be quickly adjusted for use, and in which the load will assist in holding the bracket in position.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings: v

Figure 1 is an elevation of a bracket con structed in accordance with the invent-ion and shown in position for use.

Figure 2 is a front view.

Figure 3 is a top view showing the studding of a building in section.

Figure 4 is a plan view of the clamp.

Figure 5 is an edge view of the same.

Figure 6 is a front elevation of the foot.

Figure 7 is a section on the line 77 of Figure 6.

Figure 8 is a fragmentary perspective view showing the outer end of one of the bars of the bracket.

Figure 9 is a detail perspective view of one of the stud engaging members.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates a pair of stud engaging members which may be formed as shown of a single length of material shaped to provide spaced apertured cars 11 for the reception of pivot pins 12. These pins serve to pivotally connect the inner ends of substantially horizontally disposed arms 13 to the stud engaging members 10 and the latter are held in posi tion upon the studs 14 by means of pins 15, or through the medium of pins 16 which pass through the sides of the stud engaging members and enter openings provided in the studs. The pins are secured to the stud engaging members by chains 17 so that they will not become lost and the pins 16 may be likewise secured if desired.

The arms 13 are adapted to extend outward and are shaped so that their outer ends are relatively close and are pivotally connected to a clamp which is indicated generally by the reference character 18 in F igure 4 of the drawings. This clamp comprises a wedge 19 having an opening 20 therein, while extending through this wedge are spaced cars 21 which carry a pivot pin 22. The outer ends of the arms 13 are pivotally secured to the wedge by means of this pin..

Movable freely within the opening 20 provided in the wedge 19 is a substantially T- shaped link 23 which extends beyond the inclined edges of the wedge and is provided with openings 24. The link 23 is also provided with an elongated slot 25 through which the pivot pin 22 passes, sothat the link which is received between the outer ends of the arms 13 has a sliding pivotal connection with these arms.

The openings 24 of the link 23 receive the outer ends of inclined bars 26. These bars are provided with notches 27 which are engaged by the link and their lower inner ends are mounted upon a pivot pin 29 which is carried by spaced ears 30. These ears form a part of a foot 31 which is adapted to bear against the sheathing or wall 32 which is carried by the studs 14. This foot is pivotally secured to the lower ends of hanger bars 33 whose upper ends are secured to the members 10 as shown at 34.

The foot 31 is provided with spaced lugs 35 having notches to receive the pivot pin 29 and these lugs serve to space the lower ends of the bars 26 apart.

In the use of the invention for applying sheathing to studding, the sheathing is applied in the ordinary manner to a desired height. The sheathing is then notched as shown at 36 in Figure 3 of the drawings, the notch being of a sufiicient depth to receive the stud engaging members 10. This permits of the stud engaging members being positioned so as not to interfere with the continuation of the sheathing. The bars 26 are then inserted within the openings 24 of the link 23, the said bars having a sliding fit within these openings. The link is engaged within the notches 27 and the weight of the scaffold (indicated by the dotted lines S in Figure 1 of the drawings) will act to force the wedge 19 between the bars so that the link will be firmly seated within the notches 27. The wedge may move independently of the link due to the sliding engagement between the link and wedge'and the elongated slot 25 in said link. It will be apparent that increased load upon the scaffold will only serve to force the wedge further outward between the bars 26 v and thus increase the clamping or gripping action.

\Vhile the bracket is shown and described in connection with a building under construction, it is obvious that it may be used by inserting the stud engaging members 10 through a window or other opening in a building and engaging these members with studding temporarily positioned within the window. The foot which carries the inclined bars 26 will then engage the outer face of the building.

The invention is susceptible of various changes in its form, proportions and minor details otconstruetion and the right is here in reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is 1. In a bracket, a horizontally disposed arm, means to removably secure the inner end of said arm to the stuclding of a building, a pair of pivotally mounted upwardly and outwardly extendingbars, means to support the pivoted ends of the bars from the studding engaging means, a wedge pivotally secured to the outer end of the horizontally disposed arm, and a link carried by said wedge and having a sliding connection with the pivotally mounted bars.

2. In a bracket, a horizontally disposed arm, means to removably secure the inner end of said arm to the studding of a building, a pair of pivotally mounted upwardly and outwardly extending bars, means tov support the pivoted ends of the bars from the studding engaging means, a wedge pivotally secured to the outer end of the horizontally disposed arm, and a link carried by and slidable with respect to the wedge and having a sliding pivotal engagement with the horizontally disposed arm and a sliding connection with the pivotally mounted bars. 7

3. In a bracket, a pair of spaced horizontally disposed arms, means to removably secure the inner ends of the arms to the studding ot a building, a pair of upwardly and outwardly extending bars, means to pivotally support the lower ends of said bars from the arm securing means, a wedge pivotally secured'to the outer ends of the horizontally disposed arms, and a link carried by said wedge and having a sliding pivotal engagement with the horizontally disposed arms and a sliding connection with the pivotally mounted bars.

In a bracket, a pair otspaced hori-' zontally disposed arms, means to removably secure the inner ends of the arms to the studding of a building, apair of upwardly and outwardly extending bars, means to pivotally support the lower ends of said bars from the arm securing means, a wedge pivotally secured to the outer ends of the horizontally disposed arms, and a substantially T-shaped link carried by and extending be yond the edges of the wedge and having openings therein to slidingly receive the bars, and also having a sliding pivotal connection with the horizontally disposed arms.

In testimony whereof I my signature.

JOHN ROMYAK.
