Improvements in or connected with Fans for Attachment to
Bedsteads or Tables, or for use in other Situations.
I, ARTHUR HOWARD HIEATZMAN, of Baltimore City, in the State of Maryland,
United States of America, merchant, 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 invention relates to a portable fan, for attachment to bedsteads or tables, or for
use in other situations.
The object is to provide means whereby a fan, of any suitable kind, revoluble or
swinging, to be driven by a spring clock-work motor, may be attached to an article of
furniture such as a bedstead or a table.
The invention is illustrated in the accompanying drawings, in which-
Fig. 1 is a side view of a bedstead with the fan attached. Fig. 2 is a top view of
same. Fig. 3 is a side view of the brace-bar on a larger scale. Figs. 4 and 5 are
side and top views (the latter partly in section) of one of the clamps. Fig. 6 is a
view of the suspension-bar. Fig. 7 shows two views of a modified form of clamp.
Figure 8 is a view of a fan, its supporting arm, extension-bar and clamp adapted for
attachment to a table or a desk.
The ordinary bedstead A has head-posts b, and the supports of the fan are attached
to the posts by clamps C.
The fan D is preferably of the revolving pattern and turns on the spindle e, which
has bearings fattached to the board or arms G, which also has a spring clock-work
motor H. An endless cord I connects the pulleys of the motor with the spindle e of
the fan. It is unnecessary to describe the mechanism of the motor, as any such
motor now in use may be employed. Furthermore, it may be remarked that the fan
may be driven by any preferred power, such as a water or an electric motor. The
supporting arm G, at the opposite end from the fan, has two hooks j, which take over
a suspension-bar K, extending horizontally across the front of the head-board 7, and
serve as hinges. The ends of the suspension-bar are supported in bearings m,
attached to the clamps C. The suspension-bar K is extensible-that is, capable of
being lengthened or shortened-so as to fit beds of varying width. This extensible
feature is obtained by a tubular centre n and two end rods n¹, each inserted in
an opposite end of the said tube, as shown. A brace-bar O has one or
hooks P,
which take over the suspension-bar K, and the lower end of the brace-bar
sets down between the suspension-bar and head-board 1, and the bar has an inclined
position. A cushion on the extremity of the lower end prevents the head-board
from being marred. The top of the brace-bar O and the fan-supporting arm G have a
suitable connection ". This connection in the present instance consists of a jointed
rod r, and serves to sustain the arm G. The joint in the rod may be bent or
thrown up, and thus the arm G and fan D may be raised to get it out of the way
when it is desired to "make up" the bedding. This plan of securing the brace-bar O,
with its lower end below the suspension-bar K, gives it stability and fixedness, and
thereby the arm G and fan D are properly supported directly over the occupant of
'the bed.

The clamps C, for gripping the posts b of the bedstead, each have a jaw s attached
rigidly to the same plate that forms the bar-bearing m and also a movable jaw s¹.
These jaws are, faced with a suitable cushion t to prevent marring the posts. The

has a hole U, and the end of the suspension-bar K passes through this hole, and also
through the bearing m, and thereby the cam-lever is pivoted on the end of the
suspension-bar. The eccentric circular head w of the cam-lever fits in a ring *,

attached to the movable jaw s'. . By this construction the clamp-jaws will be moved
upon partly turning the lever u. This clamp will fit bed-posts of varying breadths.
A modification in the construction of the clamp is shown in Fig. 7. Here a set-
screw u¹ is employed to move the jaws s'. It is obvious that different forms of clamps
may be employed. It is therefore unnecessary to illustrate other modifications.
Instead of the upper brace-har O and rod r, connecting with the arm G, I may use
a lower brace like an ordinary bracket-brace, as indicated by broken lines in
Fig. 1.
This fan as shown in Figures 1 and 2 will fit any bedstead. It may be readily put
up and taken down, and when attached to a bed it may easily be raised above its
normal position to give unobstructed access to the bed-clothing when it is desired to
make up the bed.
The fan shown in Figure 8 will be readily understood. The supporting arm G
is attached to the upper end of the extension bar K, which, in this case is upright,
and the clamp C will grasp the edge of a table or a desk by turning the screw v.
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 :
1. In a portable fan, the combination of the arm G, the fan D, journailed in one
end of said arm, the suspension-bar K, the clamp C, in which said bar has bearings,
the brace-bar O, the connecting-rod r, and clamp mechanism, as described, wheroby
the suspension-arin is held in position over the bed, substantially as specified.
2. In a portable fan, the combination, with the arm G, secured to the extension-
bar K by means of hooks j, of the jointed bar r, brace-arm O, clamps C, and cam-
lever u, whereby the arms G and bars and O are held in an adjusted position,
substantially as set forth.
3. In a portable fan for bedsteads, the combination, with the arm G, suspension-
bar K, and jointed arm r, and clamps C, of the cushion q, secured to the end of the
brace-bar O, to bear against the head-board of the bed and prevent injury to the same,
as set forth.
4. The combination of a supporting arm, an extension-bar holding said arm, a
clamp; and a motor-driven fan attached to said supporting arm.
