Claim 1
Independent Claim
213 words
A connection system for steel beams comprising a. a pair of abutting fittings, one designed to be fastened to a support beam or column and the other to a framing beam, each fitting being provided with a plurality of parallel grooves on each of its sides, and each fitting having a notch in that face which abuts the other fitting, said notches matching to form a hole extending through the abutting fittings, b. a female tongue plate provided with parallel tongues which enter the grooves on one side of the two fittings when axially aligned with each other in abutting relationship, and having a hole extending through the plate, c. a male tongue plate provided with parallel tongues which enter the grooves on the side of the two fittings opposite the female tongue plate when the grooves of the two fittings are axially aligned with each other, and having a stud projecting from the plate for extending through the hole formed by the matching notches in the fittings and the hole in the female platE, and d. a nut on the free end of the stud drawing the tongue plates toward each other and connecting the plates fittings together to thereby connect the support and framing beams to which the fittings are fastened.

Claim 3
Dependent Claim
24 words
The connection system defined by claim 1, in which the grooves of the two sides of each fitting are staggered relatively to each other.
Claim 4
Dependent Claim
30 words
The connection system for steel beams defined by claim 1, in which the grooves on each side of the abutting fittings extend parallel to the axis of the framing beam.
Claim 5
Dependent Claim
52 words
The connection system for steel beams defined by claim 1, in which the notches on abutting faces of the fittings are semicircular in shape to form a round hole extending through the fittings and axially at right angles to the grooves in the fittings, and the said stud has a round shank.
Claim 6
Dependent Claim
52 words
The connection system for steel beams defined by claim 3, in which the fittings are provided with additional grooves on opposite sides which extend at right angles to the grooves which are parallel to the axis of the framing beam, and the tongue plates include ribs for seating in said additional grooves.
Claim 7
Dependent Claim
62 words
The connection system for steel beams defined by claim 1, in which one of the fittings is provided with an attachment plate parallel to the abutting face of the fitting for attachment to a support beam, and the other of the fittings is provided with an attachment plate parallel to the web of a framing beam for attachment to said framing plate.
