- INVENTORI 2Z @fi Patented July 8, 1930 PATET' GFFICE GEORGE B. BOSGO, OF CHICAGO, ILLINOIS T-HEAD BRACKET Application filed May 23,

The main objects of this invention are to provide improved means for securing two timbers together in abutting relation; to provide an improved form of head bracket for securing the cross piece of a T-head to the post; and to provide an improved head bracket of this kind which will permit the cross piece and post to be quickly assembled and dis mantled.

An illustrative embodiment of this invention is shown in the accompanying drawing, wherein Figure 1 is a side elevation of a T-head to which an improved bracket is applied, part of the post being broken away.

Figure 2 is a transverse section taken on the line 22 of Fig. 1.

Figure 3 is a section taken on the line 33 of Fig. 1.

Figs. 4 and 5 are perspectives of the two sections of the improved bracket.

The improved bracket to which this invention is applied is adapted for securing abutting timbers together in various structures but, in the construction illustrated, it

is applied to the T-head of a shore, such as are commonly employed in concrete construction work.

In the form shown, the T-head comprises a cross piece 1 and a post 2, which are preferably 1X41 timbers.

The improved bracket comprises a pair of complementary sections 3 and 4 arranged in substantially parallel spaced relation to each other, so as to embrace the timbers 1 and 2. The sections 3 and 4 are preferably metal castings and each comprises a base part 5 and a pair of upwardly diverging arms 6 and 7.

Formed in the ends of the arms 6 and 7, are apertures 8 for receiving bolts 9 extending through the cross piece 1. Formed on the inner faces of the arms 6 and 7 adjacent the apertures 8, are teeth 10 adapted to cut into the cross piece. Shoulders 11 are formed on the outer faces of the arms 6 and 7 of the section 3 for engaging the bolt heads to secure the bolts 9 against turning.

Formed on the inner faces of the base parts 1 5, is a pair of inwardly projecting ledges 12 1929. Serial No. 365,486.

which abut against one face of the post 2. Engaging the opposite face of the post 2, is a wedge 13, seated in slots 14 and 15 formed in the sections 8 and 4: respectively.

Extending between the sections 3 and 4, adjacent the wedge 13, is a spacer sleeve 16 mounted on a bolt 17, which is supported on the base parts 5. Shoulders 18 are mounted on the outer face of the section 3 in position to engage the head of the bolt 17 for securing the bolt against turning.

The base parts 5 are offset outwardly from the planes of the arms 6 and 7, so as to permit the bracket to fit around posts which vary slightly in width.

In operation, the sections 3 and 4 are bolted to the cross piece 1 and then, when it is desired to assemble the T-head, the post 2 is inserted into the bracket between the shoulders 12 and the wedge 13. When the two timbers are in abutting relation, the wedge 13 is driven into firm engagement with the post 2.

I claim:

1. A head bracket for securing a pair of F abutting timbers together comprising a pair of separately formed sections arranged in substantially parallel spaced relation to each other so as to be adapted to embrace the timbers, means for rigidly securing said sections to one of the timbers, said sections having openings forming a keyway, a wedge seated in said keyway for engaging one side of the other timber, a pair of inwardly projecting flanges integrally formed on said sections for engaging the opposite side of said other timber, and spacing means located between said sections adjacent said wedge.

2. In a head bracket for securing the cross piece to the post of a T-head, a pair of separately formed complementary sections arranged in substantially parallel spaced relation to each other so as to be adapted to embrace the cross piece and post, each of said sections comprising a. base member and a pair of diverging arms, bolts extending through said arms for attachment to the cross piece, the base members of said sections being offset outwardly from the planes of said arms, a pair of inwardly projecting ledges integrally formed on said sections for tions.

Signed at Chieago this 21st day of May,

GEORGE B. BOSCO.
