The object of this Invention is to provide a new and improved rotary sample
stand for exhibiting samples of embroidery, photographs, pictures or any other
articles.
The apparatus consists of a reel shaped frame constructed of a pair of discs fixed
to the ends of a tubular body and tied together by rods, the said frame being
mounted to rotate on a vertical spindle rising from a suitable foot into the tubular
body of the rotary frame. Between the top and bottom discs of this rotary frame
skeleton frames or wings suited for holding the photograph or other article to be
exhibited are loosely pivoted by their upper and lower inner corners the said pivots
being received in corresponding sockets near the edges of the discs. The said frames
are easily removable from the central frame and the latter may be made without
the central tubular body above referred to the lower disc turning on the spindle and
the upper disc having a downwardly projecting central pivot which is received in
a corresponding socket in the top end of the spindle or standard.

page_text: The central frame in which the wings are
mounted and from which they
stand out on all sides, can be rotated by a clock-train contained in a casing beneath
the central frame and gearing therewith, or by any other suitable motor or by
band. A spring is mounted on any fixed support so as to project in the way of
the wings or frames so that when the stand is rotated the outer end of each wing
or frame will strike against said spring and be thereby detained so that the sample
upon the face of the wing can be distinctly seen. Or a U shaped spring may be
provided having small rollers at its ends which project in the path of the lower
edges of the wings or frames, said spring being fixed to the standard beneath the
rotary part of the frame and having its vertical shanks passing through guides in
fixed bracket arms.
If the frame be turned around rapidly, the centrifugal force will swing the wings
outward and their lower edges will strike the rollers on the ends of the spring and
will press the latter downward, thus permitting the wings to pass; but if any two
wings are to be held open when the frame does not revolve, the rollers hold the
wings.
Or a spring wire coiled to increase its elasticity and having its ends secured to
the standard is bent to a semicircular form and so placed as to press against the
lower edges of the wings and hold them in whatever position they may be placed

frame. Or a flat ring or segment of a ring is applied in the same position and is
carried on fixed arms by sockets sliding on the upwardly turned ends of said arms

ALEXANDER MELVILLE CLARK of the firm of A. M. and W. Clark of 53 Chancery
Lane in the county of Middlesex Fellow of the Institute of Patent Agents
"IMPROVEMENTS IN ROTARY STANDS FOR EXHIBITING PHOTOGRAPHS, SAMPLES,
AND ARTICLES FOR SALE." A communication to me from abroad by Christian
Augustus Schmidt, of the city, county, and state of New York, United States of
America.
The object of this invention is to provide a new and improved rotary sample
stand for exhibiting samples of embroidery photographs, pictures or any other
articles.
Reference is to be had to the accompanying drawings forming part of this
specification in which similar letters of reference indicate corresponding parts in all
the figures.
Figure 1, is a longitudinal elevation of the improved rotary sample stand, parts
being shown in section. Figure 2, is a plan view of the same. Figure 3, is a
sectional elevation showing a modification. Figure 4, is a sectional plan view of
the same. Figure 5, is a sectional elevation of another modification of the means
for holding the wings open. Figure 6, is a sectional plan view of the same. Figure 7,
is a sectional elevation of another modification.
A spindle A is secured on a base B which spindle is provided in its upper end
with a bearing for a disc D united with a like disc D¹ by rods E. The frame
formed by the discs D D¹³, and the rods E can turn freely on the spindle or
standard A. the bottom disc being provided with an aperture through which the -
said spindle can pass. The discs D D¹ are secured to the opposite ends of a tubular
shaft C into which the spindle A passes as shown in Figure 1. F F are frames or
skeleton wings which have short pivots G, formed upon or attached to their inner
lower corner, and long pivots H attached to or formed upon their inner upper
corners. The lower pivots G can pass into sockets or apertures in the lower disc D¹
near its outer edge, and the upper pivots H can pass into bearings or through
apertures J in the upper disc D near its outer edge. The wings F are made a littlo
shorter than the space between the discs D D¹, as shown, so that the said wings can
be detached by raising the pivots G out of their sockets or apertures I, then drawing
the wings outward and lowering them to withdraw the pivots H from their
bearings or apertures J. The frame formed by the discs D D₁ and the rods E, can
be revolved by a clock work mechanism L L' contained in a casing K surrounding
the spindle A or by any other suitable motor, or if desired, the device can be
constructed without any motor and be revolved by hand. To the wall of the room
or to any other suitable support or standard a spring M is fastened which projects
from the wall, so that when the stand is rotated the outer end of each wing F
can strike against the said spring and be detained so that the samples upon the
face of the said wing can be distinctly seen.
Referring to the modification shown in Figures 3 and 4 the spring M has been
dispensed with, and a U shaped spring N is held in a bracket arm N' projecting
from the standard, and on the upper ends of the said U shaped spring N small
rollers n are held. The vertical shanks of the U shaped spring N, pass through
guide eyes m, formed on the outer ends, of rods m¹ projecting from the standard A
If the frame formed by the discs D D' and the rods E is turned around rapidly,
the centrifugal force will swing the wings F outward and the lower edges of the
wings will strike the rollers n on the ends of the spring N and will press the

page_text: ends of the spring downward, thus permitting the wings to pass; but if any two
wings are to be held open when the frame does not revolve, the rollers n project
slightly above the lower edges of the said wings and hold the wings as shown in
Figure 3.
In the modification shown in Figures 5 and 6 spring wire O is coiled to increase
its tension, and has its ends secured to the standard A and the top part O' of the
wire is so located that it will be pressed against the lower edges of the wings F
and will also hold the wings in position in which they are placed. The friction of
this spring is not so great as to prevent the revolving of the rotary frame.
In the modification shown in Figure 7 a ring P or a ring section is held on a
series of arms Q projecting from the standard A, which ring is pressed upward by
springs R surrounding the vertical shanks of the arms Q. The springs press the
ring against the lower edges of the wings F so that the friction of the ring will be
sufficient to hold the wings in any desired position, at the same time permitting the
rotary frame to be revolved freely if sufficient power is applied.
The construction can be further modified in various different ways, but in all
cases the rotary frame carrying the wings is combined with a spring for holding
one or more wings open. Samples of embroidery, upholstery goods, knitted goods,
dry goods, hardware, cutlery, etc, can be held on the wings by suitable bands, or
can be cemented to the same. The rotary frame can carry any desired number of
wings according to the size of the apparatus.
Having described the nature of the said Invention and the manner of performing,
the same I declare that what I claim as the invention to be protected by the
herein before in part recited Letters Patent is :
1 In a rotary sample stand, the combination with a vertical spindle or standard,
of a rotary frame provided with wings, and of a spring device for holding the said
wings open so that the samples thereon can be seen, substantially as herein shown
and described.
2nd The combination with the spindle A, of the discs D D¹, united by rods E,
the skeleton wings F, pivoted to the discs D D', and a spring device for holding
the wings open, substantially as herein shown and described.
3rd The combination with a standard, of a revolving frame provided with
hinged wings, of a motor for revolving the rotary frame, and of a spring device for
holding the wings open, substantially as herein shown and described.
In Witness whereof I the said Alexander Melville Clark have hereunto set my
hand and seal this 29th day of March 1884
