Improvements in Bioyoles.
I, SIDNEY AUSTIN GRANT, of 55 Sherman Street, in the City of Springfield,
State of Massachusetts, United States of America, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to Improvements in Bicycles of the class set forth in the
Letters Patent of the United States granted to me November 21, 1893, number
509,079; the object being to simplify the construction of the gear driving connec-
tions and to render the parts very easy of assemblage, and stronger and cheaper;
and to these ends the invention consists in constructions and combinations of parts
all substantially as will hereinafter fully appear.
The crank axle is mounted, as usual, in the "bracket" which is equipped with
suitable ball bearing parts, and the bracket is provided with rearwardly extended
lugs.
On the fixed rear wheel axle is mounted for rotation the hub of the rear wheel.
The axle is supported on what may be regarded as the rear fork legs of the bicycle
frame, the forward extremities of which have supporting engagements with the
aforesaid bracket lugs.
One of said fork leg members is tubular and is comprised in the machine, substan-
tially as in the aforesaid Patent, while the other fork leg member is a solid stay-
rod, and has its forward portion screw-threaded; it is formed with the enlarged
cylindrical and screw-threaded part, near its rear end, and has its rear end
formed with the squared and bifurcated part, the space between the separated
members thereof opening to the rear end of the said stay-rod.
The forward end of the stay-rod screws into the screw-threaded socket-lug of the
bracket, and said rod receives the one end portion of the rear wheel axle within the
inner boundaries of the space within the bifurcated part.

The block with the concaved forward edge sets closely between the extremities
of the members of said bifurcated part and is held by the bolt and nut which is
passed through the angularly turned rear end portion of the rear upper oblique
member, of the diamond frame, and through the perforations in the bifurcated' part
and said block.

The hub of the rear wheel has the bevel gear wheel thereon, and a bevel gear
wheel, is also fixed on the crank-shaft.
gears,
A tube surrounds the said stay rod and has at its ends the fixed bevel
engaging with other gears. Each of the gear wheels has its inner portion suitably
cupped, or concaved, to receive the bearing of the balls which are between it and
the cone, screwing on the threaded portions of the shaft, the extremities of which
cones serve as the direct parts of support for the gears, and the tube, connecting
them.
In the assemblage of the novel parts of this bicycle the internally threaded cone
(with its check-nut) is first slipped on at the forward end of the stay-rod and passed
rearwardly to a screw engagement on and well to the rear of the screw enlargement.
The tube and gears are next placed to surround the stay-rod and the cone for the
forward gear (with its check-nut) is then placed on the threaded part. The stay-
rod is then turned to screw engagement with the socket-lug of the bracket, and then

In this bicycle it will be seen that the axle for the rear wheel and the crank-
shaft bracket are strongly and rigidly united by the stay-rod, and that said rod
forms adequate and practical supports for the adjustable annular parts or cones
which impart the support to the gears and the tubular connection.

Improvements in Bicycles.
I, SIDNEY AUSTIN GRANT, of 55 Sherman Street, in the City of Springfield,
State of Massachusetts, United States of America, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to Improvements in Bicycles of the class set forth in the
Letters Patent of the United States granted to me November 21, 1893, number
509,079 the object being to simplify the construction of the gear driving connec-
tions and to render the parts very easy of assemblage, and stronger and cheaper;
and to these ends the invention consists in constructions and combinations of parts
all substantially as will hereinafter fully appear and be set forth in the claims."
The improvements are fully and clearly illustrated in the accompanying
drawings,―
Figure 1 being a side elevation of the bicycle with driving gears and the improved
connections thereon.
Figure 2 is a horizontal sectional view on a larger scale taken on the line 2-2,
Figure 1.
Figure 3 is a perspective view of the stay-rod and parts to which it is connected,
all to be hereinafter referred to.
Similar letters of reference indicate corresponding parts in all of the views.
In the drawings, A represents the crank axle mounted, as usual, in the
"bracket," B, which is equipped with suitable ball bearing parts, and the bracket
is provided with the rearwardly extended lugs, a, a².
C represents the fixed rear wheel axle on which the hub, D, of the rear wheel is
mounted for rotation.
.
The axle is supported on what may be regarded as the rear fork legs of the
bicycle frame, the forward extremities of which have supporting engagements with
the aforesaid bracket lugs.
One, b, of said fork leg members is tubular and is comprised in the machine,
substantially as in the aforesaid Patent, while the other fork leg member, d, is a
solid stay-rod, as seen in Figures 2 and 3, and has its forward portion, d', screw-
threaded; it is formed with the enlarged cylindrical and screw-threaded part, d',
near its rear end, and has its rear end formed with the squared and bifurcated
part, d, the space between the separated members thereof opening to the rear end
of the said stay-rod.
The forward end of the stay-rod screws into the screw-threaded socket-lug, a³,
of the bracket, and said rod receives the one end portion of the rear wheel axle
within the inuer boundaries of the space within the part, d.
The block, f, with the concaved forward edge sets closely between the extremities

page_text: of the members of said bifurcated part and is held by the bolt and nut, g, g², which is
passed through the angularly turned rear end portion, h³, of the rear upper oblique
member, h, of the diamond frame, and through the perforations in the bifurcated
part and said block.
The hub of the rear wheel has the bevel gear wheel, i, thereon, and a bevel gear
wheel, j, is also fixed on the crank-shaft.
A tube, k, surrounds the said stay-rod and has at its ends the fixed bevel
gears, m and n, respectively, engaging with the gears, i and j. Each of the gear
wheels has its inner portion suitably cupped, or concaved, to receive the bearings
of the balls which are between it and the cones, o, or p, screwing on the threaded
portions of the shaft, the extremities of which cones serve as the direct parts of
support for the gears, m, n, and the tube, k, connecting them.
In the assemblage of the novel parts of this bicycle the internally threaded cone
(with its check-nut, o³,) is first slipped on at the forward end of the stay-rod and
passed rearwardly to a screw engagement on and well to the rear of the screw
enlargement, . The tube and gears are next placed to surround the stay-rod and
the cone for the forward gear (with its check-nut, p³,) is then placed on the
threaded part, d. The stay-rod is then turned to screw engagement with the
socket-lug, a', of the bracket, and then the rear wheel being brought to its bearing
support the parts, d and f, and h³, are united by the bolt and nut, 9, I.
In this bicycle it will be seen that the axle for the rear wheel and the crank-
shaft bracket are strongly and rigidly united by the stay-rod, and that said rod
forms adequate and practical supports for the adjustable annular parts or cones
which impart the support to the gears, m, n, and the tubular connection, k.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a bicycle, the combination with the bracket with the socketed and screw-
tapped lug, a, and the crank-shaft with the gear, of a stay-rod having its forward
end threaded and entering with a screw engagement the said lug, and by its rear
end supporting the axle for the rear wheel, the rear wheel having on its hub the
gear, i, and the tube with gear wheels thereon, surrounding, and supported for
rotation by, said stay-rod, with its gears meshing with the crank-shaft and rear
wheel gears, substantially as described.
2. In a bicycle, the combination with a bracket, A, of a stay-rod having at its
forward end a supporting connection with the bracket, and having at its rear end
the bifurcated part, d', for constituting a one-end support for the rear wheel axle,
and the rear oblique frame member, h, having the angular extremity, h², the block, f,
and the bolt passed through perforations in said parts, h³, f, and d', substantially as
described.
3. In a bicycle, the combination with the rear wheel axle and the bracket, and
the rear wheel with 'the gear, i, and the crank-shaft with the gear, j, of the stay-
rod for supporting the rear wheel axle and having a supporting connection with the
bracket and having the screw-threaded portions, d* and d, near its ends, and the
tube with gear wheels thereon surrounding the stay-rod, the cones, o and p,-
Laving support by, and screw engagement with, the threaded portions of the stay-
rod, between which and the tube gears are included the balls, substantially as
described.
4. In a bicycle, the combination with the rear wheel axle, and the bracket having
the threaded socket-lug, a², and the rear wheel with the gear, i, and the crank-shaft
with the gear, j, of the stay-rod having the screw-threaded portion, d³, at its forward
end, partially entered in said socket-lug, and having the enlarged screw-threaded
portion, d, near its rear end and also having its rear end constructed for a one-end
sapport of the rear wheel axle, the tube, k, surrounding the stay-rod and having
the gears, m and n, and meshing with the aforesaid gears, i and j, the cone, o,

page_text: screwing on the enlarged screw-threaded part of the stay-rod, d³, and the cone, p,
screwing on the threaded part, d', to the rear of the socket-lug, between which
cones and the tube gears are comprised the balls, substantially as described.
