page_text: We, THEO ENDEAN, photographer and FREDERICK GEORGE CLARK, broker, both of
Cleveland, Ohio, 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 :-
Our invention relates to chairs for sitters in photographer's galleries and consists of
the peculiar construction and combination of parts herein described. Reference being
made to the accompanying drawing in which
Fig. 1 is a side elevation of the chair with part of the pedestal B broken away to
more fully exhibit the details of construction.
Fig. 2 is a plan of the chair.
Fig. 3 is a side elevation of the arm rest with the infant attachment adjusted
thereto.
Fig. 4 is a plan of the infant attachment.
Figs. 5, 6, 7, 8 and 9 are parts of the chair as indicated by the letters thereon.
Fig. 8 shows the ring U in section and fig. 9 a plan of the same.
B is a
In the drawings A is a platform which we make preferably in circular form and
is mounted on castors a, a, for the convenience of readily moving it about.
hollow pedestal secured to the central part of the platform A.
C is a revolving seat supported on the pedestal B, by means of a central spindle D
which has a shouldered and reduced portion d' the latter being encased in a spiral
spring E which rests on the platform A with its upper end bearing against the
shoulder d on the spindle D and supports the seat C a short distance above the top of
the pedestal B as shown in fig. 1. The lower end of the spindle D protrudes below
the platform A and engages with one end of a lever F fulcrumed at about its center
to a short hanger secured to the bottom of the platform A. The other end of the
said lever F carries a brake pad G which is made to bear upon the floor upon which
the chair stands by means of the spring g. The purpose of this brake is to prevent
the chair from moving while a person is stepping on the platform and while not

page_text: seated and the arrangement is such that the weight of the sitter depresses the lever F
and lifts the brake pad G from the floor so that the operator can easily move the
chair and sitter about for adjustment of position.
At the back of the seat C is attached a double bracket H to which is pivoted an
upright arm I which supports the adjustable back rest J. The arrangement is such
that by means of the spring pawl and the sliding motion of the back-rest J a perfect
adjustment of the back-rest to the height and position of the sitter may be obtained
and when the chair is used with the infant attachment, as hereinafter described, the
back-rest and arm I may be turned down out of the way.
On the lower side of the seat C is fixed a spring-pawl or catch O which by engaging
in the notches in the top flange of the pedestal B holds the seat in any required
position. The opposite end of the pawl O projects beyond the seat C in the form of
a handle o by which means the pawl may be disengaged when it is required to revolve
the seat for adjustment of position.
At one side of the seat Cis attached an adjustable arm rest consisting of a bracket K
having a slot for the upright rod k which supports the arm rest and thus by means
of the sliding head and set screws m, m the arm rest can be adjusted to the desired
height and distance from the seat. To the upright rod k is attached an arm M with a
socket and set screw m² on its outer end for retaining and adjusting the upright rod N
to which are fastened the adjustable clamps n, n and n¹n and the head rest n¹¹.
M, m³, N n, n, n', n' and "n¹¹ constitute what we for convenience term the infant
attachment.
In photographing infants the arm rest L is used for them to sit upon, with their
feet resting on the seat and they are held in position with the clamps n n adjusted
to fit around their hips and the smaller clamps n', n², adjusted under their arms, while
there may be used any desired form of head rest as n".
To the platform A is attached an adjustable head rest support Q which is a hollow
post suitable for the reception of any desired form of head rest. The post Q is
adjustably attached to the platform A by means of a swinging arm P which is pivoted
at or near the center of the underside of the platform A and is guided in its swinging
motion by the small rollers s, s, 5, 8, two of which are carried by a cross arm pp
attached to the arm P in such a manner that they roll on the under curved edge of the
platform A when the head rest holder is moved from side to side, and the other two
rollers 3, s, are attached to the post Q by means of the cross head bar R in such a
manner that they traverse the upper curved edge of the platform A on the metal
track s¹, s¹. A brake or lock is provided for holding the hoad-rest in position at the
side of the platform, consisting of the lever T pivoted through post Q and so arranged
that its inner end passes through a hole or slot in the bar R and by means of the rod t
and cam lever t¹ may be made to bear on the edge of the platform A, thus locking the
post Qin a fixed position. To the pedestal B is attached an adjustable screen holder
consisting of the loose ring U the fixed ring u' and the rods V W, w and X. The
ring U is fitted on a journal or ledge on the pedestal B and kept in position by means
of a fixed ring u or by any suitable method so that the ring U may revolve freely
around the pedestal B and yet sustain an extended arm to which a screen may be
attached. On one side of the ring U is a lug u shown in enlarged size in figs. 8 & 9.
The lug u is so constructed that a rod or arm V may be hooked into it as shown in
the dotted lines V₁ and that when the arm V is lowered to a horizontal position, it
will be thus sustained and kept from rolling on its axis like a fixed arm on the ring U
and yet be easily detachable at will. To the outer end of the arm V is joined at va
hollow tubular rod W in which slides a smaller rod to the top end of which is joined
the arm or handle X of any desired form of screen Y.. It will be readily seen that
the revolving ring U will enable the screen to be turned to any side of the chair at
will and the joints and being arranged to clamp with set screws and the arm
composed of the rods W and w to lengthen and shorten, the screen may be easily set
in any fixed position to obscure or reflect rays of light as may be required.
The seat, back-rest and arm-rest may be upholstered and the platform carpeted
making a very neat comfortable and convenient chair for photographer's use.

page_text: Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is:
1. In a photographer's chair the combination with the platform A supported on
castors a, a, of a pedestal B supporting a revolving seat C adjustable to position by the
spring pawl O and having a central spindle D setting in the pedestal B upon the
spring E said spindle also coming in contact with and operating the brake lever F
and brake pad & substantially as specified.
2. The combination of a revolving seat C provided with an adjustable back rest J
supported by the several parts I i and H substantially as described.
3. The combination with the seat C of the adjustable arm rest L supported by
the several parts K, k, I and m m substantially as set forth.
4. The combination with the arm rest L of the infant attachment consisting of the
several parts M m¹ N n, n n', n' and n" substantially as specified.
5. The combination with the platform A of the adjustable head rest holder made up
of the various parts P, Q, R, S, T, p, s¹ s¹t and t¹ substantially as described.
6. The combination with the pedestal B of an adjustable screen holder consisting of
the several parts U, u, u³, V, v, W, w, X, x, and Y substantially as set forth.
