Bicycle Stand.
I, FREDERICK VAN GERPEN, of 241, E. 78th Street, New York, in the County
and State of New York, Bookkeeper, 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 stands for bicycles in which the frame for holding the
bicycle is pivoted on its support so that the said bicycle may be turned into any
position for the purpose of repairing and cleaning; and has for its object to
provide a holding frame to which any bicycle can be secured with the greatest ease;
a further object being to provide a pivotal connection between the frame and
supporting standard of special construction whereby the stand can be manufactured
at a very small cost.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which the similar parts of my improvements
are designated by the same numerals of reference in each of the views, and in
which-
Fig. 1, represents an elevation of my improved bicycle stand;
Fig. 2, is a view of the pivotal connection on an enlarged scale, the same being
partly in section, and also shows a part of the holding frame with a plan view
of one of the clamping devices; and,
Fig. 3, is a view of my improved stand showing a bicycle secured thereto.
Referring to the drawing, 5, represents the foot, which may be of any convenient
form, 6 is the supporting standard, preferably tubular in form, 7 represents the
socket, which is composed of two parts 8, and 9 bolted together at 10; the part 8
being provided with a base 11, having a flange 12, and cylindrical extension 13,
adapted to fit in the tubular standard 6, as clearly shown.
The socket 7 is provided on the upper side thereof with a slot 14. 15, represents
the ball, and 16 a cylindrical standard secured thereto, or integral therewith;
and to the standard 16 is secured by means of a bolt, or screw 17, the holding
frame 18.
The frame 18 is T-shaped in form, and is provided at each of the free ends
with a longitudinal slot 19. On each of the free ends of said frame, I mount
a sliding block 20, provided with a screw-threaded shank 21, on which I mount
a nut 22, by which the said block may be secured in position, as will be readily
understood.
Each clamp consists of two semi-circular jaws, 23, and 24, pivoted to the block 20
at 25, and adjustably connected together at the free ends by a bolt and thumb
nut 26; but I have shown this form simply to illustrate one method of attaching
the frame of a bicycle to the holding frame. Any clamping device may be used,
the only object being to provide a clamping device which would be adjustable in
each of the slots 19.
I also provide a set screw 27, which is mounted in a tapped hole in the spherical
socket 7, and is provided with a handle 28, and the inner end is adapted to bear
against the ball 15, as will be readily understood.
The operation of my device is as follows: by reason of the adjustable clamping
device at each free end of the T-shaped frame, any form of bicycle frame may.

page_text: easily be secured to the holding frame, and in any required position, which would
not be the case if only one of the clamping devices were adjustable. When the
bicycle is secured in position, the same may be turned around in a vertical plane by
reason of the cylindrical standard 16, or may be swung into a horizontal plane by
reason of the slot 14, in which the said standard 16 is free to move.
The ball 15 is preferably made of cast iron, while the set screw 27 is preferably
made of hardened steel adapted to cause a slight abrasion in the ball 15 when
turned tightly against the same; and by this construction the ball 15 may fit quite
loosely in the socket, and need not be smooth; but the interior of the socket and
the ball may be used as they come from the mould, and by reason of the abrasion of
the ball by the set screw 27, a slight recess will be formed therein in connection
with which the said ball will be held fixed in any position by the said set screw,
and with it, the holding frame and bicycle mounted thereon.
"
By this construction I am able to produce a stand possessing. the
advantage of stands of more complicated construction at a cost much below
those now on the market and I do not, therefore, limit myself to the exact con-
struction and arrangement of parts, but reserve the right to make all changes
which fairly come within the scope of my invention.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a bicycle stand, a ball and socket joint, consisting of a ball, a socket
in which said ball is loosely mounted, and means to hold said ball in a fixed
position in said socket, consisting of a set screw, the end of which is adapted to
engage the ball and abrade the same, substantially as herein specified.
2. In a bicycle stand, a holding frame T-shaped in form, and provided with
adjustable clamping devices in each of the free ends thereof, substantially as
herein specified.
3. A bicycle stand, comprising a support; a holding frame pivotally connected
therewith, said pivoted connection consisting of a ball and socket joint; and
means to hold the holding frame in any relative position consisting of a set screw
mounted in the socket of said ball and socket joint, the end of which is adapted to
abrade the surface of said ball, and hold the same by the recess formed by said
abrasion in conjunction with the frictional contact of the ball and opposite wall of
the socket, substantially as herein specified.
4. A bicycle stand, comprising a support; a spherical socket mounted in the upper
end thereof; a ball mounted therein; a set screw adapted to abrade said ball, said
ball being provided with a cylindrical standard which extends through a slot
formed in the upper side of said socket; a holding frame secured to said standard,
said frame being T-shaped in form; and adjustable clamping devices mounted on
the free ends of said holding frame, substantially as herein specified.
5. A bicycle stand, comprising a support; a spherical socket mounted in the
upper end thereof, and provided with a slot in the upper side thereof; a ball
mounted loosely in said socket, and provided with a cylindrical standard adapted
to pass through said slot; a T-shaped holding frame mounted on said standard,
and provided with a longitudinal slot in each of the free ends thereof and a clámp
adjustably mounted in each of said slots; and a set screw mounted in said socket,
the end thereof being adapted to engage the surface of said ball, and abrade the
same, substantially as herein specified.
