Abstract
Abstract The disclosure describes a support for a stationary drainage element for a paper machine extending across the Fourdrinier wire. The support comprises a flaring tenon for a dovetail slide incorporating means to adjust the distance between the flaring walls. The drainage element has a mortise slot for cooperating with the slide. The flare of the slide is adjusted by means of an actuator mounted at one end of the support. This abstract is intended neither to define the invention of the application, which is to be measured by the claims, nor in any way to be limiting as to the scope of the invention.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
124 words
A flaring tenon for a dovetail slide having side walls which extend in a first direction and diverge transversely to said first direction from a narrow part to a wide part of said tenon, said side walls being made of sheet-form wall members in a position providing a first distance between them at said wide part, a base member and means mounting said wall members on said base member at said narrow part, adjusting cam means movable in said first direction within said wide part of said tenon and cooperating means on said tenon for engaging said cam means and thereby altering the distance between said members in the vicinity of said wide part when said cam means is moved in said first direction.
Claim 2
Dependent Claim
124 words
A flaring tenon for a dovetail slide having side walls which extend in a first direction and diverge transversely to said first direction from a narrow part to a wide part of said tenon, said side walls being made of sheet-form wall members in a position providing a first distance between them at said wide part, a base member and means mounting said wall members on said base member at said narrow part, adjusting cam means movable in said first direction within said wide part of said tenon and cooperating means on said tenon for engaging said cam means and thereby altering the distance between said members in the vicinity of said wide part when said cam means is moved in said first direction.
Claim 3
Dependent Claim
124 words
A flaring tenon for a dovetail slide having side walls which extend in a first direction and diverge transversely to said first direction from a narrow part to a wide part of said tenon, said side walls being made of sheet-form wall members in a position providing a first distance between them at said wide part, a base member and means mounting said wall members on said base member at said narrow part, adjusting cam means movable in said first direction within said wide part of said tenon and cooperating means on said tenon for engaging said cam means and thereby altering the distance between said members in the vicinity of said wide part when said cam means is moved in said first direction.
Claim 4
Dependent Claim
124 words
A flaring tenon for a dovetail slide having side walls which extend in a first direction and diverge transversely to said first direction from a narrow part to a wide part of said tenon, said side walls being made of sheet-form wall members in a position providing a first distance between them at said wide part, a base member and means mounting said wall members on said base member at said narrow part, adjusting cam means movable in said first direction within said wide part of said tenon and cooperating means on said tenon for engaging said cam means and thereby altering the distance between said members in the vicinity of said wide part when said cam means is moved in said first direction.
Claim 5
Dependent Claim
142 words
A flaring tenon for a dovetail slide having side walls which extend in a first direction and diverge transversely to said first direction from a narrow part to a wide part of said tenon, adjusting cam means slidable in said first direction within said tenon between said side walls and cooperating means on said tenon for engaging said cam means and thereby altering the distance between at least a portion of said side walls, actuating means located at one end of said tenon for sliding said adjusting cam means in said first direction within said tenon, the cross-section of said actuating means in a plane parallel to a transverse section of said tenon being smaller than said transverse section, so that a body having a mortise slot cooperating with said tenon can pass over said actuating means while sliding on said tenon.
Claim 6
Dependent Claim
142 words
A flaring tenon for a dovetail slide having side walls which extend in a first direction and diverge transversely to said first direction from a narrow part to a wide part of said tenon, adjusting cam means slidable in said first direction within said tenon between said side walls and cooperating means on said tenon for engaging said cam means and thereby altering the distance between at least a portion of said side walls, actuating means located at one end of said tenon for sliding said adjusting cam means in said first direction within said tenon, the cross-section of said actuating means in a plane parallel to a transverse section of said tenon being smaller than said transverse section, so that a body having a mortise slot cooperating with said tenon can pass over said actuating means while sliding on said tenon.
Claim 7
Dependent Claim
153 words
A flaring tenon for a dovetail slide having side walls which extend in a first direction and diverge transversely to said first direction from a narrow part to a wide part of said tenon, said side walls being made of sheet-form wall members providing a first distance between them at said wide part, said wall members each having a flange extending toward the other, an elongated flat adjusting member disposed between said wall members with one of its long edges located in each of the corners formed by said wall members and said flanges for altering the distance between said side walls in the vicinity of said wide part, at least one of said long edges being a cam edge, and cooperating means on said tenon located to cooperate with said cam edge to spread said wall members apart when said flat member is moved in said first direction between said wall members.
Claim 8
Dependent Claim
153 words
A flaring tenon for a dovetail slide having side walls which extend in a first direction and diverge transversely to said first direction from a narrow part to a wide part of said tenon, said side walls being made of sheet-form wall members providing a first distance between them at said wide part, said wall members each having a flange extending toward the other, an elongated flat adjusting member disposed between said wall members with one of its long edges located in each of the corners formed by said wall members and said flanges for altering the distance between said side walls in the vicinity of said wide part, at least one of said long edges being a cam edge, and cooperating means on said tenon located to cooperate with said cam edge to spread said wall members apart when said flat member is moved in said first direction between said wall members.
Claim 9
Dependent Claim
29 words
A tenon according to claim 1 in which said adjusting means is a flat cam that is slidable in said first direction within said tenon between said side walls.
Claim 10
Dependent Claim
24 words
A tenon according to claim 4 including actuating means located at an end of said tenon for sliding said adjusting means within said tenon.
Claim 11
Dependent Claim
59 words
A tenon according to claim 1 in which said wall members are each made from a separate shallow V-shaped piece of flexible material having first and second flat portions, the first flat portions of each member being fixed to said base member, and the second flat portions extending from said base member flaring outwardly therefrom to form said tenon.
Claim 12
Dependent Claim
43 words
A tenon according to claim 2 in which said actuating means comprises a first element fixed relative to said tenon and a second element fixed relative to said adjusting means, and operator means to move said second element relative to said first element.
