D. H. BITNEY STRUCTURAL UNIT Oct, 6, 1931.

Filed Aug. 16, 1929 ll INVENTOR fi'z/ny /7. 5/7/76 6% ATToiE yi Patented Get. 6, 1931 nnrren s'rA'rEs PATENT OF E DEVEY H. BITNEY, OF ALBION, MICHIGAN, ASSIGNOR- 'IO' UNION STEEL PRODUCTS COM- PANY, OF ALBION, MICHIGAN STRUCTURAL UNIT Application filed August 16, 1929. Serial No. 386,281.

The main object of this invention is to provide an improved structural unit adapted for the attachment of sleepers or furring strips to reinforcing bars or beams in concrete structures.

A-further object is to provide a structural unit of this character which may be quickly attached to its supporting element without the aid of tools, and is adapted for the engagement of supporting elements of considerable variation in size.

Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of my invention is clearly illustrated in the accompanying drawings, in which:

1 is a. fragmentary perspective view of a structural unit embodying the features of my invention, a joist or reinforce beam and a sleeper being shown by dotted lines in operative relation to the structural unit.

Fig. 2 is a fragmentary section on line 22 of Figs. 1 and 2.

Fig. 3 is an enlarged detail of the structural unit.

Fig. 4 is a fragmentary plan view illustrating the springing of the longitudinal memher to permit engagement of the unit with the supporting element.

In the accompanying drawing 1 represents an I beam and 2 a sleeper. My improved structural unit comprises a longitudinal rod 3 and a plurality of support engaging members 4 disposed transversely of the longitudinal rod and secured in fixed relation thereon by welding as indicated in Fig. 3. These support engaging members 4 are arranged in spaced pairs, the members of the pairs being spaced to receive an element to be attached such as a sleeper furring strip or the like indicated at 2.

The support engaging members are provided with hooks 5 adapted to be engaged with the flange of the I beam 1, the hooks of alternate pairs of the members 4 being oppo sitely disposed to engage opposite edges of the beam.

The members 4 terminate in eyes 6 at their upper ends adapted to receive nails 7 whereby the sleepers 2 are secured thereto.

In use these structural units are engaged with the beams prior to the pouring of the concrete and the members 4 are of such length that their outer ends project from the surface of the concrete to receive the members to be attached such as the sleepers 2.

By this arrangement the sleepers or other elements attached are directly connected to the beams or joists. This not only provides very secure anchoring means for the attached elements but they are accurately positioned.

The longitudinal supporting rod may be sprung to permit engagement of the hooks 5 with the supporting member and also to adapt the unit to supporting members of different widths.

I have not attempted to illustrate or describe other embodiments or adaptations of my improvements as it is believed that this disclosure will enable those skilled in the art to embody or adapt the same as may be desired. 1

Having thus described my invention what i I claim as new and desire to secure by Letters Patent is:

1, A structural unit comprising a longi= tudinal supporting rod of springable mate rial, and a plurality of support engaging members disposed in spaced coacting pairs transversely thereof and fixedly secured thereto and having hooks at their lower ends adapted to be engaged with the flange of a beam or like structural element by springing the longitudinal rod and held in engagement therewith by the resilience of the rod, the hooks of adjacent pairs of support engaging members facing oppositely, the upper ends of said support engaging members terminating in eyes facilitating the attachment thereto of a sleeper or like element.

2. A structural unit comprising a longitudinal supporting rod of springable material, and a plurality of support engaging members disposed in spaced coacting pairs transversely thereof and fixedly secured thereto and having hooks at one end adapted to be engaged with the flange of a beam or like structural element by springing the longitudinal rod and held in engagement therewith by the resilience of the rod, certain of the hooks facing oppositely, the other ends of said support engaging members terminating in eyes facilitating the attachment thereto of an element to be attached.

3. A strhetural unit comprising a longitudinal rod of springable material, and a plurality of transversely disposed support en- 'gfigihg members fixed to said rod in spaced coacting pairs and having hooks at one end engageable with a supporting structural element by springing the longitudinal rod and held in engagement therewith by the resilience of the rod, part of the hooks facing in one direction and part in the opposite direction whereby they may be engaged with opposite edges of the supporting element, the opposite ends of the support engaging members constituting attaching members for an element to be attached.

In witness whereof I have hereunto set my hand. W
