Grayson County, Texas, United States of America, do hereby declare the nature
of this invention to be as follows:
The object of the present invention is to provide a bicycle attachment whereby
the rider is enabled to support the feet while travelling or to support the bicycle
in a vertical position when not in use to securely lock the wheel to prevent the
machine from being stolen.
a rod
The Invention consists principally of brackets each mounted on
movable on the fork of the steering wheel. Near the lower end of each of the
members of the front fork is secured a clip connected by a pivot with a lug formed
on another clip preferably made in two parts and adapted to clamp two rods
forming a frame adapted to be locked in a vertical position by a catch secured to
the first mentioned clip and adapted to engage with its cam edge a part of the other
clip at or near the middle. The frame is further arranged to engage with its
upper end a spring catch secured to a clip adapted to be attached to the upper
part of a corresponding member of the fork by a set screw for clamping the clip in
place on the member of the fork and for securing the catch to the clip. By
mounting the frame to swing on a pivot the said frame can be swung into a lower-
most position to form a bicycle support or to an uppermost position to form a foot
rest as presently to be described..
On the two rods of each frame is fitted to slide a bracket formed with teeth
on its upper edge similar to the teeth on the foot rests as now used and provided
on its outer end with braces formed at their inner ends with eyes for engaging
with the rods so as to enable it to slide up or down thereon. The eyes are adapted
to rest on a clamp preferably made in two parts clamped on the rods at any desired
height so as to bring the brackets into the proper position to suit the convenience®
of the rider. The eyes are also adapted to engage in notches formed in the rods
near their free ends so that when the brackets are in the lowermost position the eyes
will engage in the said notches to prevent the brackets from accidentally slipping
upward on the rods during the time the bicycle is supported in a vertical position
The outer or lower ends of the frames

are provided with transversely extending rods formed with right and left hand
screw threads engaged by a turnbuckle to permit of moving the two frames
towards or from each other at their free ends according to the thickness of the
bicycle wheel tyre which extends between the two frames. The rods are also
formed with upward extensions adapted to be connected with each other by a bar
passing between adjacent spokes of the wheel, the said bar being connected at its
free ends with a padlock to fasten the two frames as well as the wheel together to
prevent unauthorized persons from riding off with the machine.
By the arrangement described the rider is enabled to readily swing the two
connected frames into a lowermost position to cause the brackets to slide downward
on the rods to rest on the ground and thereby form a support for holding the

page_text: bicycle in a vertical position. When the bicycle is to be used the rider can readily
swing the connected frames into an upward position so as to engage the upper
ends
of the frames with the spring catch and the cam catch to securely hold each of
the frames in this uppermost position. When the frames move into this position
the brackets slide downward on the rods until the eyes rest on the clamps the
brackets then forming a rest for the rider's feet...
I may provide the outer ends of the rods with longitudinally extending foot
pieces adapted to bear on the ground when the device is in a lowermost position,
to assist in holding the bicycle in an upright position. These foot pieces are
preferably curved so that when the frame is in an uppermost position they can be
used for hanging bundles and other articles thereon.

Improvements in Bicycle Attachments.
I, AUGUST ZINTGRAFF, of 701, West Gaudy Street, Denison, in the County of
Grayson, and State of Texas, 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:
The object of the present invention is to provide a new and improved bicycle
attachment, whereby the rider is enabled to support the feet while "coasting" or
to support the bicycle in a vertical position when not in use to securely lock the
wheel to prevent the machine from being stolen.
The invention consists principally of brackets, each mounted on a rod movable
on the fork of the steering wheel.
The invention also consists of certain parts and details and combinations of the
same, as will be fully described hereinafter and then pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding
parts in all the figures.
Figure 1 is a front elevation of the improvement as applied and in the position
for supporting the bicycle;
Figure 2 is an enlarged perspective view of the improvement, with parts in.
section and in the position to form a foot rest for the rider ;
Figure 3 is a similar view of the improvement in position to form a support for
the bicycle;
Figure 4 is an enlarged sectional plan view of part of the improvement on the
line 44 of Figure 2;
Figure 5 is an enlarged plan view of the spring catch for holding the frame in
place when forming a foot rest, and
Figure 6 is a side elevation of a modified form of frame with the foot brackets in
section.
Near the lower end of each of the members of the front fork A of the bicycle
is secured a clip B by means of a set screw C. The clip B is also pivoted at D to.
a lug E¹ formed on a clip E whereby it may be clamped upon a pair of parallel
rods F¹ forming a frame F hereinafter referred to.
The clip E is preferably formed by two plates E³, E³, drawn together by a set
screw E so as to clamp the rods F¹ tightly between them,

page_text: Attached to the clip B by the set screw C is a catch plate G adapted to be
sprung into engagement, by means of its cam edges with the inner member Eª of
the clip E, at or near the middle of said member, so as to lock the frame F in a
substantially vertical position.
.
The frame F is further arranged to engage with its upper end a spring catch H
secured to a clip I adapted to be attached to the upper part of a corresponding
member of the fork A by a set screw I', for clamping the clip in place on the
member of the fork and for securing the catch H to the clip. See Figure 5.
By having the frame F mounted to swing on the pivot D, it is evident that the.
said frame can be swung into a lowermost position to form a bicycle support, or
to an uppermost position to form a foot rest, as presently to be described.
On the two rods of each frame F is fitted to slide a bracket J, formed with teeth
on its upper edge similar to the teeth on foot rests as now used. Each bracket J
is provided on its outer end with braces J¹, extending inwardly and formed at
their inner ends with eyes J2 engaging with the rods F¹, so as to enable the bracket,
with its braces, to slide up or down on the rods forming the frame F. The eyes J
are adapted to rest on a clamp K, preferably made in two parts fastened together by.
set screws and clamped on the rods F1 at any desired height, so as to bring the,
brackets J into the proper position to suit the convenience of the rider. The
eyes Ja are also adapted to engage in notches F2, formed in the rods F¹ near their
free ends, so that when the brackets J are in the position shown in Figures 1
and 3, the eyes will engage in the said notches to prevent the brackets from
accidentally slipping upward on the rods, during the time the bicycle is supported
in a vertical position by the brackets resting on the ground, as will be readily
understood by reference to Figure 1. The outer or lower ends of the frames F are
provided with transversely extending rods L, formed with right and left hand
screw threads engaged by a turnbuckle N, to permit of moving the two frames F.
towards or from each other at their free ends, according to the thickness of the
bicycle wheel tyre which extends between the two frames, as shown in Figure 1.
The rods L are also formed with upward extensions L' adapted to be connected
with each other by a bar O, passing between adjacent spokes of the wheel, the
said bar being connected at its free ends with a padlock P to fasten the two frames
F, as well as the wheel, together to prevent unauthorized persons from riding off.
with the machine.
Now it will be seen that by the arrangement described, the rider is enabled to.
readily swing the two connected frames F into a lowermost position, as shown in
Figures 1 and 2, to cause the brackets J to slide downward on the rods F¹, and rest'
on the ground and thereby form a support for holding the bicycle in a vertical
position. When the bicycle is to be used, the rider can readily swing the con-
nected frames F into an upward position, (as shown in dotted lines in Figure 1
and in full lines in Figure 2) so as to engage the frame F with the spring catch H
and the cam catch G to securely hold each of the frames in this uppermost position.
When the frames move into this position, the brackets J slide downward on the
rods F until the eyes J2 rest on the clamps K, as indicated in Figure 2, the
brackets then forming a rest for the rider's feet.
In the frame F', shown in Figure 6, the outer ends of the rods F5 are provided
with longitudinal extending food pieces F6, adapted to rest on the ground when
the device is in a lowermost position, to assist in holding the bicycle in an upright
position. The foot piecu Fe are preferably curved, as shown, so that when the
frame is in an uppermost position the said foot pieces can be used for hanging
bundles and other articles thereon, thus forming a bundle carrier.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
:-
1. A bicycle attachment composed of frames and brackets adapted to slide
thereon, means for pivoting said frames to the front fork of the machine and
