PROVISIONAL SPECIFICATION.
A New or Improved Sandwich Board or Portable Advertising
Device.
1, DAVID FOSTER of "Burnside" Thorpe Road, Selby, in the County of
Yorkshire, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a new or improved sandwich board or portable
advertising device or appliance adapted to be carried on the back or in front or
both through the streets after the manner of the present well-known "sandwich
boards" only my present invention has many advantages over the ordinary
sandwich boards heretofore in use particularly in respect of being lighter and
easier to carry and morcover my invention is designed to exhibit a number of
advertisements (for instance six, ten, twelve or more advertisements on one device)
and having other improvements and advantages.
My present invention is as follows;-
I form a frame of any suitable material and size advantageously a wood frame
of oblong form of about the same size as the present sandwich boards.
At or near the top 1 journal or otherwise suitably mount a roller in any suitable
block or other suitable bearings and similarly provide another roller at or near
the bottom of the frame each such roller being provided with a grooved pulley*
around which an endless cord or chain of leather or gutta percha is passed-the
latter also passing round a winding or operating drum or pulley mounted at a
convenient point on the frame with a handle or other convenient means thereon
for the person carrying the device to thereby rotate said operating pulley and thus
revolve said rollers simultaneously. Or same may be revolved by simply pulling
the said endless cord or any other suitable or equivalent mechanism or means
may be provided by which to revolve said rollers either simultaneously or
independently.
The advertisement or advertisements are displayed on a long piece of canvas or
other suitable flexible material (for instance either painted or printed on said
material or mounted thereon) and one end of this material is secured to the
aforesaid top roller and the other end to the aforesaid bottom roller the whole of
the material (except of course the parts stretched between the two rollers) being
wound on one such roller and by operating the aforesaid winding cord or otherwise
rotating the empty roller in any suitable manner thereby the long length of
material is wound off one roller on to the other and in turn wound back again on to
the first roller (and so on backwards and forwards) so as to display in succession a
series of advertisements either relating to one or several matters or belonging to
one or several proprietors as desired.
Vertical grooves or other suitable guide-ways may advantageously be provided
on the vertical inside edge of said frame within which the edges of said long length
of canvas carrying the advertisement is guided and held in position or battens or
cross-pieces may be mounted on the back of said material to assist in keeping
same flat and guide same in such guide-ways as it passes from one roller to
the other.

page_text: I also provide an improved support or means of carrying such advertisement
"boards" or device as follows ;-
I let into or otherwise mount on the back of the frame (on each side) metal
devices having a vertical narrow slot therein with an enlarged opening at the
bottom of said slot and advantageously provide two or more such mounts down
each side so that the position of the support can be varied if desired.
The support or attachment to the person consists of a rod or arm curved round
at the top to fit over the shoulders of the carrier (sandwich-man) while at the
bottom of said arm a headed pin or stud is provided on the back thereof such head
or enlarged part of said stud passing through the enlarged hole at the bottom of
the slot in said mount and then the narrower part of said stud will pass up such
slot the enlarged head thus holding the support fast to the frame.
I do not however wish to confine myself to the foregoing special method of
supporting or carrying this advertising device as it will be obvious that any other
suitable means may be employed to support or carry said appliance as desired for
instance it may be carried by straps.
At left hand side of frame a handle may be placed if desired for the carrier to
hold the frame steady which may be hinged or be movable up and down and one
for the right hand also if found necessary.
Another advantage is that the material or medium on which the advertisement is
displayed may be of a transparent or semi-transparent character and a light
or lights provided at night-time behind said material would thus enable such
advertisements to be displayed after dark as well as in the daylight.

Improved Sandwich Board or Portable Advertising
Device.
1, DAVID FOSTER, of "Burnside," Thorpe Road, Selby, in the County of
Yorkshire, Merchant, 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 a new or improved sandwich board or portable
advertising device or appliance adapted to be carried on the back or in front or
both through the streets after the manner of the present well-known "sandwich
boards only my present invention has many advantages over the ordinary
sandwich boards heretofore in use particularly in respect of being lighter and
easier to carry and moreover my invention is designed to exhibit a number of
advertisements (for instance six, ten, twelve or more advertisements on one device)
and having other improvements and advantages.
I will now proceed to fully describe my present invention with reference to the
drawings hereunto annexed."
Fig. 1 is a plan of a double sandwich board according to my present invention.
Fig. 2 is a view of the inside-i.e. an elevation looking in the direction of the
arrow 1 Fig. 1.
vertical sectional view on line 3-3 looking in the direction of the
Fig. 3 is
arrow 2 Fig. 2.
Fig. 4 is a cross sectional view on line 4-4 Fiø. 2

page_text: Fig. 5 is
Jine 4-4.
a "local view on an enlarged scale of one corner of the frame-on
Figs. 6 and 7 are corresponding views to Figs. 2 and 3 respectively-showing a
modification i.e. a single board instead of a double one.
a is one frame (which I will term the front frame) and b is similar frame (which
I will term the back frame) these being connected by the side picces c at top and
bottom or the whole of the side may be enclosed if desired.
d is top roller and e bottom roller respectively mounted on the front frame a so
as to be free to revolve while fand 9 are corresponding rollers-also adapted to
revolve on the back frame.
def and g* are loose rollers to guide the length of material on which
the advertisements or other matter to be displayed is arranged as same is wound
off the top roller on to the bottom and vice versa which is effected by means of the
endless band or chain passing over the pulley or sprocket d¹ fixed rigidly to the
top roller d and the "idle" pulley or sprocket h¹ on the inside of the frame a-
the lower roller e being independently revolved by a separate endless band or chain i
passing over the pulley or sprocket e¹ on the said roller e and the "idle" roller t
on the inside of said front frame a. Thus by pulling round the band or chain h
the roller d is revolved and thereby winds the length of material off the roller e
while by pulling round the band or chain i the roller e is revolved and thereby the
material wound thereon off the roller d and thus the advertisement or other matter
displayed on said material is brought into view through the opening in the
fraine a.
In the case of the double frame and advertisements therein (i.e. back and front)
shown in Figs. 1 to 5-the back rollers ƒ and g may be correspondingly revolved
with and by the rollers d and e respectively as shown viz: by an endless band or
chain y passing round another pulley or sprocket wheel d² (fixed on the roller d)
and a pulley or sprocket wheel on the roller at the back and another and
separate band or chain z passing round a second pulley or sprocket e² on the bottom
roller e and a pulley or sprocket g' on the bottom roller g. Or said rollers d and e
may be revolved in any other equivalent or suitable manner and also motion may
be transmitted therefrom to said back rollers in any other suitable manner or said
back rollers may be independently revolved in any desired manner.
The frame a (and similarly with the back frame if used) is provided with a
vertical groove or equivalent on the inside edge of said frame to guide the flexible
material therein as it is wound backwards and forwards and this may advantageously
be formed by the removable bead a fixed in place by the buttons to screwed to same
and to the frame so as to be readily detachable.
vare cross-bars or bearers fixed to the back and front frames a and b Figs. 1 to 4
under which pads may advantageously be mounted to fit over the shoulders of
the person carrying this apparatus.
In the arrangement of the single device shown in Figs. 6 and 7-k is a cord or
strap fixed to-and a curved plate extending from-the frame a by the former of
which the apparatus is hung on the person carrying same while the fixed plate
rests against his body and serves as a distance piece or block to hold the frame
clear of the legs in walking.
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 apparatus for advertising or the like purposes-the combination with a
frame or case having an opening therein, of a roller arranged at each side of said
opening, a length of flexible material one end fixed to one such roller and the other
end fixed to the other said roller and adapted to be wound off one such roller onto
the other roller alternately, advertisements or other matter displayed on such
