3 Claims.

This invention relates to structural members, and particularly to a device for use in the erecting of steel scaffolding. v

At the present time, steel scaffolding is used for many purposes, such as in the construction of ships, so that workmen may safely convey materials during a ship's construction, for use by stone or brick masons in the erecting of the wall of a building, for use by plasterers, and where interior scaffolding is used by painters, carpenters, or others who must perform work within a building.

Another use for steel scaffolding is exterior a building and over a sidewalk so as to protect pedestrians upon the walk and so that workmen may either demolish or erect a building using the scaffolding as a means of access to the work.

An object of the present invention is the provision of a device for use with scaffolding which allows scafiolding to be readily braced and also I permits the ready erection of the scaifolding within a minimum of time. Ordinarily, scaffolding includes struts which are spaced apart, with bracing between the struts. This bracing is secured to the struts in various ways and the present invention provides a structural member which allows the bracing to be secured to the struts or other members rapidly, quickly and securely.

Other objects of the invention consist in the provision of a structural member, which is inexpensive in cost of manufacture, and generally superior to devices now known to the inventors for securing structural members in working relationship.

With the above mentioned and other objects in view, the invention consists in the novel and useful provision, formation, construction, association, and relative arrangement of parts, members and features, all as shown in a certain emu bodiment in the accompanying drawing, described generally, and more particularly pointed out in the claims.

In the drawing:

Figure l is a fragmentary view of the improved device of the present invention shown in cooperation with certain structural members,

Figure 2 is a sectional detail on the line 2-2 of Figure l, and on an enlarged scale from said figure, and,

Figure 3 is an enlarged sectional view on the line 3-3 of Figure 1.

' Referring now to the drawing, the structural member is termed for convenience a gooser," and said device includes a half-round or U- shaped member I, provided with a shank 2 extending laterally from one side of the member I. This member may be solid or tubular and provided with a diametric bore 3. A keeper 4 includes a bar whichis longitudinally slotted at 5, and provided with a part 6 adapted to span the legs of the U-shaped member I. A part I of the keeper is enlarged as to thickness, and likewise provided with a concave surface 8. Thus the device comprises a substantially U-shaped member provided with a shank, and a keeper member adapted to be moved to position one end thereof between the legs of the U-shaped member.

The operation, use and advantage of the device are as follows:

In scaffolding, it is ordinary practice to utilize struts with laterals extending between the struts for the purpose of bracing the struts. In Figure 1, we have shown two spaced struts at 9 and I0, and a lateral at H. In order to secure this lateral to the struts, we provide two of the goosers, with the shanks 2 received within the tubular ends of the lateral; as shown in Figure 2. A bolt I2 is passed through openings in the lateral, and the transverse or diametrlc bore 3 in the shank 2. The usual washer and nut is carried by the threads of the bolt, and the concavity 8 of the keeper 4 permits this member to embrace the surface of the lateral. As the keeper 4 is slotted at 5, it may be moved so that the portion 6 overlaps the ends of the legs of the U- shaped member I, whereupon the nut may be tightenedupon the threads of the bolt to lock the keeper 4 against movement. The same procedure is performed for the opposite end of the lateral. If it is known that the struts 9 and II! are always to be positioned a certain distance apart, then th laterals may have the shanks 2 secured within the said laterals by welding, as shown at l3. The nutand bolt arrangement is retained, however, so as to lock the keeper 4 in position of service and so that the U-shaped member embraces the strut. For instance, in

' t Figure 2, the strut 9 is received within the confines of the U-shaped member I and the keeper 4, which is a slide-lock, holds the U-shaped member and the lateral carried thereby securely to said strut.

It is evident upon viewing Figure 1 that it makes no difference whether the struts 9 and I0 are vertical or are horizontal. In fact, the gooser may be a part. of a diagonal brace, and wherein a diagonal carrying the gooser extends between two laterals. The gooser" is adaptable to structural member and for securing two members in working relationship.

we claim: 1. A structural device as disclosed, including a tubular lateral, an open-sided housing at one end of said lateral. a keeper provided with a curved surface in engagement with the surface of the tubular. lateral, and means receiving the keeper to the lateral, the keeper being movable to close the open side of the housing.

2. A structural device. as disclosed, including a tubular lateral, an open-sided housing at one end of said lateral, a keeper provided with a curved surface in engagement with the surface of the tubular lateral, means for slidably mounting the keeper to the tubular lateral, said keeper being movable to close the open side of the housing, and said keeper being formed with a shoulder to engage the housing when the keeper is closed over the open side of the housing and to limit movement of the keeperin one direction.

8. Ina structural device asdiscloeed, a U- shaped connecting member for embracing a strut a shank projecting laterally from said U- shaped. connecting member to be projected into 'an end of .a lateral structural member, a slide lock constructed and arranged to engage the outside of said lateral structural member and to overlap the open side of said U-shaped connectingmember. and a-single bolt extended through said lateral structural member, shank and slide lock, and a nut on one end of said bolt for engaging said slide lock for securing said lateral structural member, shank and slide lock to-f gether.
