By this present invention the aforesaid members are tied to each other in the
following manner :
The struts C C are attached to the front post A which is provided with vertical
slots a in each of which are inserted two clip-plates c c arranged side by side and
forming an outward projecting stem c¹.
The inner portions of said plates are spread apart and bent to forin a segmental
head c which is permanently secured to the interior of the post. The struts abut
against the post and the abutting end of each has a longitudinal slot a'. The
stem c¹ is inserted into the strut and enters the slot a' in which it is brazed. To
the sides of the stem are brazed angle-plates d d formed with flanges d' d' which
are brazed to the interior of the strut and with end flanges dd brazed to the
exterior of the post.
The upper strut C and the adjacent braces D D are attached to the central
post P by clip-plates e e as shown in Fig. 4 of the drawings.
These clip-plates are formed with segmental central portions e¹ which jointly
embrace the post P and are brazed thereon. The end portions of each of said clip-
plates extend radially from the post and are brazed to the end portions of the
adjacent clip-plate and thereby form the stem e".
The ends of the braces D D and strut C abut against the exterior of the
segmental portions e¹ and are preferably slotted longitudinally to receive the
longitudinal edges of the stems ei which are inserted into the ends of said braces
and strut. The stems are brazed in the slots and the attachment is reinforced by
the angle-plates d d herein before described brazed to the stem ell within the
strut C and to the interior of the latter and exterior of the segmental portion e' of
the clip-plates.

A is the front post, P the central post tied to the front post by struts C C',
B the steering-fork F the hanger for the crank-axle and D D₁ the rear braces.
By this present invention the aforesaid members are tied to each other in the
following manner:
The struts C C are attached to the front post A which is provided with vertical
slots a in each of which are inserted two clip-plates cc arranged side by side and
forming an outward projecting stem c¹.
The inner portions of said plates are spread apart and bent to forin a segmental
head c¹ which is permanently secured to the interior of the post. The struts abut
against the post and the abutting end of each has a longitudinal slot a'. The
stem c is inserted into the strut and enters the slot a' in which it is brazed. To
the sides of the stem are brazed angle-plates d d formed with flanges d' d' which
are brazed to the interior of the strut and with end flanges dd brazed to the
exterior of the post.
The upper strut C and the adjacent braces D D are attached to the central
post P by clip-plates e e as shown in Fig. 4 of the drawings.
These clip-plates are formed with segmental central portions e¹ which jointly
embrace the post
and are brazed thereon. The end portions of each of said clip-
plates extend radially from the post and are brazed to the end portions of the
adjacent clip-plate and thereby form the stem e".
The ends of the braces D D and strut C abut against the exterior of the
segmental portions el and are preferably slotted longitudinally to receive the
longitudinal edges of the stems el which are inserted into the ends of said braces
and strut. The stems are brazed in the slots and the attachment is reinforced by
the angle-plates d d herein before described brazed to the stem ell within the
strut C and to the interior of the latter and exterior of the segmental portion e' of
the clip-plates.

page_text: The foot of the post P and adjacent ends of the lower strut C₁ and brace D¹
are attached to the crank-hanger F in the manner illustrated in Fig. 7 of the
drawings i.e.
Three sets of clip-plates c c c are employed, one set for each of the members to
be attached to the hanger F. Each of said sets
constructed to form the
segmental cross-head e¹¹ which is brazed to the interior of the banger F and has
the stem c¹ extending through a slot in the side of said hanger and inserted and
brazed in the end of the tubular member which abuts directly against the exterior
of the hanger F, the attachment being reinforced by the angle-plates d d in the
manner bereinbefore described.
The steering-fork B is constructed of two flattened tubes ff constituting the
limbs of the fork. These limbs are united at their upper end by tie-plates 9 g, the
ends of which pass through vertical slots g' g' in the inner sides of the limbs ff
and extend across the interior thereof as shown in Fig. 9 of the drawings and are
permanently secured therein by clip-plates similar to the clip-plates c c herein-
before described, and brazed to the end portions of the tie-plates and to the interior
of the limbs ff.
These tie-plates are formed in one piece of sheet steel folded upon itself and into
the shape of a cylindrical sleeve i along the line of folding, as illustrated in Fig. 10
of the drawings. The base of the steering-fork B¹ provided at opposite sides with
vertical slots through which the tie-plates g g pass and in which they are
brazed. The sleeve i also passes through correspondingly shaped orifices in the
sides of the aforesaid base and limbs of the fork.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
1. The combination, with two metal tubes, one of which abuts with its end
against the side of the other, of a metallic coupling consisting of a stem formed at
one end with a segmental cross-head projecting laterally in opposite directions from
the end of the stem and secured contiguous to the inner peripheral surface of one
of the tubes, the stem of the coupling passing through the side of said tube and into
the abutting end of the adjacent tube, and angle-plates on opposite sides of the stem
and brazed to the interior of the latter tube as set forth.
2. The combination, with two metallic tubes, one of which abuts with its end
against the side of the other, of a metallic coupling consisting of a stem formed of
two plates fastened together side by side passing through the side of one tube and
into the abutting end of the adjacent tube, angle-plates on opposite sides of the
joined plates and brazed to the interior of the latter tube, the opposite end of the
combined plates being spread apart and bent segmental shape to conform to
the inner peripheral face of the first named tube and fastened thereto as set forth
and shown.
3. The combination, with two metallic tubes, one of which abuts with its end
against the side of the other and both slotted longitudinally at their junctions, of
a coupling consisting of a stem formed at one end with a segmental cross-head
secured contiguous to the inner peripheral surface of one of said tubes, the stem
passing through the slot in the side of said tube and into the slot of the abutting
end of the adjacent tube, angle-plates on opposite sides of the stem having
longitudinal flanges seated on the interior of the latter tube and formed with end-
wings lapping onto the exterior of the other tube inside of the abutting tube, and
brazings uniting all of said parts substantially as described and shown.
4. In combination with the central post P, the clip-plates e e e formed with
segmental central portions embracing said post and each of said plates having its
end portion extending radially from the post and contiguous to those of the
adjacent clip-plate, the strut C and braces D D abutting against the exteriors of
the aforesaid segmental portions and provided with longitudinal slots in their
abutting ends and receiving in the slots the end portions of the clip-plates, and the

page_text: angle-plates brazed to opposite sides of said end portions and to the interiors of the
strut and braces as set forth and shown.
5. The combination, with two metallic tubes, one of which abuts end wise against
the side of the other, of a metallic coupling consisting of a stem passing through
the side of one tube and formed at its inner end with a segmental cross-head
conformed to and brazed to the interior of said tube, the outwardly projecting stem
being inserted into the end of the abutting tube, and angle-plates brazed to opposite
sides of the stem and formed with longitudinal flanges brazed to the interior of the
abutting tube, and with end-flanges brazed to the side of the companion tube,
substantially as set forth.
6. The combination with the steering-post, of the fork B formed of flattened
tubes ff united by tie-plates g g passing through the inner sides of the tubes and
across the interiors thereof, clip-plates hh brazed to the end portions of the tie-
plates and to the interiors of the tubes, said tie-plates being formed in one piece
folded upon itself and formed with the cylindrical portion i along the line of folding
and passing through corresponding slots and orifices in the base of the steering-post
substantially as set forth and shown.
