COMPLETE SPECIFICATION.
An Improved Bicycle Stand.
I, RALPH DE CLAIRMONT, of the City and County of San Francisco, State of
California, a citizen of the United States and a Colonel and Staff Officer, my
present address being 330 Sutter Street, Room No. 3, at said City of San
Francisco do hereby declare the nature of my invention and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement :—
This is an apparatus, or stand, for keeping the so-called safety bicycles, when not
in use, in a safe, firm, upright position, allowing the wheels to revolve, whilst
cleaning, or adjusting, the machine. The same apparatus, being adjustable to all
kinds and sizes of wheels, can be used for both the front and rear wheels; or two
of the stands may be used, one for each wheel, for still greater convenience.
The drawing, in duplicate, accompanying this Specification, consists of five views,
or figures.
Figure No. 1 represents the base, or bed plate, made of cast iron, 18 inches long
and 9 inches wide.
Figure 2 represents one of two entirely equal uprights made of cast iron,
16 inches high from base, 3 inches wide on top, 5 inches at base and inch thick,
to be set parallel on the base plate.
Figure 3 represents the lower end of the 2 uprights with D cross braces, or
projections, to insure solidity and prevent side shake;
Figure 4 represents the upper end surface of each upright, having 2 grooves, or
sockets, one side being beveled from the center one inch down; and
Figure 5 represents the dock, or stand, when set up and ready for use.
DETAILED DESCRIPTION.
Figure 1.-Base, or bed-plate.--To be made of cast iron, 18 inches long and
9 inches broad, hollow underneath, with 6 feet, or projections, (see Figure 5),
inch high by one inch long; bed-plate to be inch thick and inch rim all around
the plate underneath, so that the base-plate, when laid on the ground, will be
inch high by inch hollow underneath. The edges of the bed-plate, all around
the upper surface, will be slightly rounded off. The bedplate is marked "A."
The 4 circles, marked "a," represent 4 circular holes through the bed plate,
inch in diameter, to receive the screw-ends of the uprights, that is to say one of
the two uprights (see Fig. 2 & 3 "F"), the other upright fitting into the two
open slots B, 34 inches long by inch wide, the two slots being semicircular at
their inner ends; these slots "B" receive the two screw-ends of the upright.
The circular holes "a" being one inch apart from each other in the long
direction of the base-plate, allow the one upright to be shifted one inch to the left,
and the slots B allow the other upright to be shifted any distance to the right up
to 3 inches, so as to be able to receive any size wheel, according to the width of
the hub, or axle. The dotted lines, forming 2 crosses, represent the lower ends
of the 2 uprights, when screwed down in their original places, 34 inches clear from
each other, inside. The curved lines in the bedplate and the 2 open spaces are for
the purpose of reducing the weight of the plate. The right and left hand ends of
the baseplate will be 24 inches broad and the 4 other sides but one inch broad each.
The open spaces at the right and left ends of the baseplate will be 1 inch from the
edge of the plate, the left hand opening being larger, there being no slots on that
side of the plate. Therefore the left opening will be 3 inches long and the right
hand opening 14 inches long. The space on the narrow part of the bed plate

page_text: between the 2 inner holes and the inner slot-ends, will be about 6 inches across, and
here is, where the wheel of the bicycle will be rolled in before lifting it into the
grooves of the uprights.
Figure 2.-The uprights.-Made of cast iron, 16½ inches high from bedplate,
3 inches wide on top and 5 inches wide at the base; inch thick. The lower end
of each upright, which are entirely alike, as given in Fig. 2, and of precisely the
same dimensions, are provided with 2 screw-ends, inch in diameter and inch
long, 3 inches apart from each other, said screw-ends "F" fitting into the
holes "a" in Fig. "A" and into the slots "B" in Fig. "A." The screw-ends
are tightened underneath the bedplate by means of square nuts, a trifle less
than inch thick: 4 nuts being required in all. The upper end of the uprights,
3 inches wide and inch thick, is provided with two semicircular grooves, or
sockets, 1 inch long by inch deep, inch distant from each other and 1 inch
from the corners. These grooves are for receiving and holding the axle-nuts, or the
hub-ends of the wheel, which will thus be suspended in said grooves and revolve
clear from the bed plate. There are 2 braces projecting from the lower center of
each upright, one outside, 2 inches long and one inside, one inch long, as shown in
Fig. 3D"; these braces are for the purpose of placing the uprights solid on the
bedplate, (see dotted lines Fig. 1 and "D" Fig. 3).
Figure 4. represents the top surface of each upright, showing the 2 grooves, or
sockets. One half of this top is beveled off from the center to the edge of the
upright, 1 inch down, to inch in width, in order to leave room for certain
attachments ending in the axle-end of the wheel in certain makes of bicycles.
Figure 5 shows the dock, or stand, set up for use: A is the bed plate, "a" the
circular holes, B the slots, C the 2 uprights, D the side braces and E the grooves,
or sockets. The screw-ends F are not visible in this figure, being inside and
underneath the bedplate, secured by nuts.
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 :
1st. That the two uprights, as represented by Fig. 2, allow the wheels of the
bicycle to be suspended on the grooves, or sockets, marked "E," and to revolve,
when thus suspended, instead of standing fast on the ground.
2nd. The adjustability of the uprights to any width of axle, by means of the
circular holes "a" and the slots "B," in the bedplate Figure 1.
T
3rd. The double grooves, or sockets, on the top ends of the uprights, Fig. 2 "E,"
which enable the dock, when adjusted to the corresponding width, to be used for
the rear wheel as well as for the front wheel of the bicycle.
4th. The peculiar construction and weight of the dock, or stand, will keep the
bicycle in a firm, secure and upright position, without any danger of falling
sideways.
5th. The dock, or stand, when unlimbered, occupies a comparatively small
space and is easily packed and transported.
