JOHN BOULTBEE BROOKS of Birmingham in the County of Warwick
Manufacturer "IMPROVEMENTS IN THE CONSTRUCTION OF SADDLES OR SEATS OF
BICYCLES TRICYCLES OR OTHER LIKE PURPOSES".
My Improvements relate first to the Air Bags or receptacles used in saddles or
sents for Bicycles or Tricycles referred to in my application for Patent N° 5135
dated the twenty eighth day of October one thousand eight hundred and eighty
two and consists in constructing the said air bag or receptacle with a hole or holes
in the most suitable part so as to correspond with a perforation or perforations
inade in the leather or other covering of the saddle or seat thus producing complete
ventilation and greatly reducing the heat caused by the use of air bags or
receptacles in such Saddles or seats when riding. In manufacturing Saddles or
Scats of this description I use the perforated base plate as described in my said
former application
To further assist in producing the desired elasticity in such seats instead of
inserting the air bag or receptacle as described in my former application before
referred to between the ordinary covering and the metal base or frame, I form the
base of wood Iron or Steel and on the top of this base I secure at both back and
front a metal plate leaving a space nearly the whole length of the saddle between
the said base and plate This metal plate has an opening formed in it for inserting
the air receptacle or bag into the seat and being in a corresponding position to the
hole or holes in the air bag or receptacle the necessary ventilation is afforded, the
said opening in the metal plate being covered over when desired by a pierced or
perforated plate of suitable shape and secured by nuts and pins or otherwise. Tho
air bag or receptacle is covered with leather perforated in a corresponding position

page_text: to the hole in the bag and perforation in the metal plate or plates, thus completing
the saddle or seat thoroughly ventilated and yielding to the weight of the rider.
As a modification I may dispense with the air bag or receptacle in which case
the metal plate made of Steel or other elastic metal (pierced for ventilation or not
as desired) is secured to the base only at the back end the spring plate being
curved or corrugated to the front end from about the middle and resting on the
front end of the base which is shaped in a corresponding manner thereby leaving
the front end of the spring plate free to slide on the front end of the base according
to the weight or pressure of the rider the plate being covered with leather as in
the former case thus producing a most comfortable ventilated and yielding seat
If desired to assist in the elasticity of the seat I may introduce a suitable spring
or springs between the base and the spring plate.
As a further modification instead of securing the base and spring plate together
at the back end of the saddle or seat I secure them together at the front end,
leaving the back end of the base and spring plate free and between them I insert
a spring or springs secured to the spring plate or base which affords the necessary
elasticity to the weight or pressure of the rider.

by the said John Boultbec Brooks in the Great Seal Patent Office on the
9th July 1883.
JOHN BOULTBEE BROOKS of Birmingham in the County of Warwick
Manufacturer IMPROVEMENTS IN THE CONSTRUCTION OF SADDLES OR SEATS OF
BICYCLES TRICYCLES OR OTHER LIKE PURPOSES.
My improvements relate first to the air bags or receptacles used in saddles or seats
for bicycles or Tricycles referred to in my application for Patent No. 5135 dated
twenty eighth day of October one thousand eight hundred and eighty two and
consists in constructing the said air bag or receptacle with a hole or holes in the
inost suitable part so as to correspond with a perforation or perforations made in the
leather or other covering of the saddle or seat thus producing complete ventilation
and greatly reducing the heat caused by the use of air bags or receptacles in such
saddles or seats when riding-In manufacturing saddles or seats of this description
I use the perforated base plate as described in my said former application
To further assist in producing the desired elasticity in such seats instead of
inserting the air bag or receptacle as described in my former application before
referred to between the ordinary covering and the metal base or frame I form the
base of wood Iron or Steel and on the top of this base I secure at both back and
front or at the back only a metal plate leaving a space nearly the whole length of
the saddle between the said base and plate. This metal plate has an opening
formed in it for inserting the air receptacle or bag into the seat and being in a
corresponding position to the hole or holes in the air bag or receptacle the necessary
ventilation is afforded the said opening in the metal plate being covered over
when desired by a pierced or perforated plate of suitable shape and secured by nuts
and pins or otherwise-The air bag or receptacle is covered with leather perforated
in a corresponding position to the hole in the bag and perforation in the metal
plate or plates thus completing the saddle or seat thoroughly ventilated and
yielding to the weight of the rider.
As a modification I may dispense with the air bag or receptacle in which case
the metal plate which may be made of steel or other metal but not necessarily
elastic as the required elasticity is obtained by the insertion of the springs
between the base and plate hereafter referred to and more fully described and
illustrated by the accompanying description and drawings this plate pierced for
ventilation or not as desired is secured to the base by preference at the back end
the metal plate being curved or corrugated to the front end from about the middle
and resting on the front end of the base which is shaped in a corresponding manner
thereby leaving the front end of the metal plate free to slide on the front end of
the base or its equivalent according to the weight or pressure of the rider, the plate
being covered with leather as in the former case thus producing a most comfortable
ventilated and yielding seat-If desired to assist the elasticity of the seat I insert
a suitable spring or springs between the base and the metal plate
As a further modification instead of securing the base and metal plates together
at the back end of the saddle or seat I secure them together at the front end,
leaving the back end of the base and metal plate free and between them I insert a
spring or springs secured to the metal plate or base which affords the necessary
elasticity to the weight or pressure of the rider-But in order that I may be better
understood as to the details or manner of giving effect to my Invention I will
proceed to describe same aided by the accompanying Drawings reference being
mado to the letters and figures marked thereon

page_text: DESCRIPTION OF DRAWINGS
Figure 1. represents in top view the air bag or receptacle constructed according
to the first part of my invention with the hole or space left in centro marked A A.
for the purpose of ventilation but which may bo otherwise formed as there may be
a series of holes formed in same in suitable positions according to requirement as
indicated by the dotted lines a. a. B. represents the tubo and scrow mouthpicco
through which the air is blown when the bag or receptacle is being inflated
Figure 2 represents the underside view of a saddle constructed according to the
second part of my invention
Figure 3-is a section of same which consists of a rigid base or frame
marked C. C. which may be stamped cast or otherwise formed of any suitable
metal and to the rear part of which I attach by the screw bolts and nuts D. and E.
or their equivalents a metal plate marked F. F. the foro or front end being
connected or attached to the base C. by the end marked G. of the base C. engaging
or working in the socket of a corresponding shape marked H attached to the
plate F. by the rivets b. b. to complete the saddle, tho plate F. is attached by the
rivets c. c. c. c. to the under part or piece of the leather covering marked J. and K.
which consists of two pieces of leather or other suitable material sewn or connected
together in the ordinary manner thereby forming a connection for the plato F. and
a covering for the air bag or receptacle the saddle being thus completed (with tho
exception of the padding or stufling usually placed in same) it is ready for the
insertion of the air bag or receptacle which is readily effected by passing same
through the opening left for that purpose marked L. L. shown at the section-
Figure 3. also by the detached views of the plate F. at Figures 4. and 5. the opening
is then covered over by the perforated plate marked M. shown detached at
Figure 6. with the perforations marked m. m. m. m. the said plate is secured in
position by the end marked d. engaging in the slot f. on the supporting plate F.
also by the slots g. g. passing over the small bolts h. h. or their equivalents on the
plate F. and secured by the nuts k. k. the air bag or receptacle is then inflated by
aid by the screw mouthpiece and the saddle is ready for use-The opening A. A.
allows a free current of air to continually pass through to the body of the rider as
represented by arrows and dotted lines in the sectional view at Figure 3. the air
passing through the perforations m. m. m. m. in the plate M. and through the said
openings A. A. in the air bag and then through corresponding holes in the leather
covering K. the saddle is connected to a Bicycle or other velocipede by the screw
bolt N. in the ordinary manner
Figure 7. represents in full side view-Figure 8. in section and Figure 9. plan of
the underside of a saddle or seat for Bicycles or Tricycles constructed according to
the third part of my invention in this case the air bag or receptaclo is dispensed
with the part forming the seat or upper part of the saddle is constructed in the
ordinary manner consisting as before described of two or more pieces of leather or
other suitable material marked J. K. as in the former figures but in this case the
space between the two parts is filled or stuffed with suitable padding as shown in
the section Figure 8. this is supported by the plate F. connected to this part in a
modified form marked F. by the rivets n. n. n. n. passing through the said
plate F. the strengthening or supporting leather P. and the leather J. of the
covering, the fore or front end being connected by the rivets o. o. o. (which also
connects the socket H. to the said plate) this is then connected at the back end to
the Base C. by the screw bolts or pins D. D. passing through slots in the Base and
secured by the screw nuts E. E. as shown at Figures 8. and 9. the front or fore end
of the Base marked G. engaging or working in the socket H. of the plate F. as
before described to give the required elasticity to the plate F1 and thereby to the
upper part of the saddle or scat the spring Q. is placed in position between the
Base C. and plate F¹. as shown in the section at Figure 8. which is also assisted by
the small spiral or other suitable spring S in the socket H the spring Q. being kept

page_text: in position by the washer K. rivetted to the base C. thus completing the saddle or
seat, the parts marked p. p. p. p. are holes for ventilation
Figure 10. is a detached view of the plate F'. Figures 11. and 12 represent top
and edge views (partly in section) of a further modification of the plate Fl. and
Base C. constructed according to the fourth part of my Invention-In this case
I connect or attach the plate marked F". to the fore or front end of the base C. by
the end G. fitting into the socket H. this being kept in position by the rear or back
end of the said Base marked O. (which in this case is formed in corresponding
shape to the rear part of the leather covering or the back part of the plate F'.)
being connected to the upper or padded part of the seat by rivets or otherwise
The springs Q. and S. being placed in position as in the former figures 8. and 9.
and having the same effect as before described.
Having now described the nature and object of my invention it will be seen that
the same is capable of considerable modification without departing from the spirit
of my said invention but what I claim by these iny in part recited Letters Patent
is firstly the construction of the air bags or receptacles having a hole or holes
formed in centre or other suitable position for the purpose of ventilation also the
arrangement of the supporting plate and base for such saddles and seats as
represented at Figures 1. 2. and 3. of the accompanying drawings, secondly, the
general construction and arrangment of the parts for forining saddles or seats as
represented at Figures 8. 9. 10. 11 and 12. or any mere modification of same.
In witness whereof I the said John Boultbee Brooks have hereunto set my
hand and seal this seventh day of July in the year of our Lord ono
thousand eight hundred and eighty three.
