Patent 2,307,396 issued January 5, 1943, in the sliding
table top bracket of my Patent 2,659,641 issued Novem
ber 17, 1953, and in the adjustable bracket of my Patent
2,723,891, issued November 15, 1955.
An object of the present invention is to provide a uni
tary bracket having an adjustable bracket arm which
operates on a different principle than heretofore, ‘and
which is cheaper to manufacture.
This is accomplished by providing a unitary bracket,
preferably in the form of a metal stamping, wherein the
junction of the forward end of the base and the offset
portion leading to the bracket arm serves as a knee or
pivot point, with fastening means in the bracket adjacent
around the head of a screw 25, providing a swivel coupling
between the head of screw 25 and base 11. The sloping
wall 22 provides a bearing surface for the outer half of
notch 24, with end 23 having loose engagement with the
inner half of notch 24 so that base 11 can tilt with respect
to the axis ‘of screw 25. When the screw 25 is screwed
out, the inner half of notch 24 engages rounded end 23 to
push the base 11 outwardly. Base 11 is thus forced in
or out as the screw 25 is screwed in or out. The rounded
end 23 is offset outwardly from the plane of base 11 by
one half the height of notch 24, so that the base of the
head of screw 25 is ?ush with the inner surface of base 11
as shown in FIG. 5, whereby the base 11 will be in con
tact with the table top 1 when the screw 25 is screwed
at the outer end of the base to tilt the bracket arm to an 25 all the way in the table top.
