Abstract

A positive fastener-angling device for positioning an elongated fastener with respect to the face of a sheet metal connector and a wood member only at a preselected angle which is substantially less than 90.degree. by forming a slit-cut in the sheet metal connector by means of a die which progressively at the same station, forms a fastener guideway in the shape of a half cone. The fastener opening and the guideway are dimensioned so that the fastener can only penetrate the sheet metal connector at a preselected angle set at the factory.

Claims8

Dependent claims

In a positive fastener-angling connection comprising:

a. a wood holding member;
b. a wood held member having a generally planar portion;
c. a sheet metal connector attached to said wood held member and to said wood holding member;
d. said sheet metal connector includes
1.) a side member having a generally planar side face portion for close registration with said generally planar portion of said wood held member;
2.) a generally straight line slit- cut in said generally planar side face portion of said side member having an edge;
3.) guideway means die-formed in said side member in the general shape of one half of a cone having a curved wall, an apex and a base and said guideway means forming a pre-selected angle with said planar side face portion of said side member which is substantially less than 90.degree.;
4.) said generally straight line slit-cut and said guideway means form a fastener opening and guide;
e. an elongated fastener having a shank, a portion of which has a constant cross section dimensioned for insertion through said generally straight line slit-cut and guideway means and into said wood held member;
f. said guideway means in said side member of said sheet metal connector is formed with a wall having a length and strength sufficient to unyieldingly hold said shank of said fastener in combination with said edge of said generally straight line slit-cut at said preselected angle during the driving of said fastener into said wood held member;
g. said fastener opening in said side member of said sheet metal connector has the general shape of a triangle having an arcuate apex, two generally equilateral arcuate sides and a generally straight base;
h. said fastener opening is dimensioned to receive said fastener and is dimensioned generally equal to or slightly less than the diameter of said fastener shank portion;
i. said fastener shank when inserted through said fastener opening is engaged by said wall of said guideway means at least at two longitudinally spaced points and at least one point on said edge of said generally straight line slit-cut at a location radially spaced from said two longitudinally spaced points on said guideway means and at a location longitudinally between said two longitudinally spaced points on said wall of said guideway means, and
j. said shank of said fastener is held at said preselected angle of said guideway means only by said generally straight line slit-cut and said guideway means in said generally planar side face portion of said side member.
