AN IMPROVEMENT IN SADDLES FOR BICYCLES, TRICYCLES, VELOCIPEDE BOATS, AND SUCH LIKE VEHICLES OR VESSELS
Year: 1885

page_text: J, JAMES ALFRED LAMPLUGH of the firm of. Lamplugh and Brown of
Birmingham in the County of Warwick, Saddle Manufacturers, do hereby
declare the nature of my invention for "AN IMPROVEMENT IN SADDLES FOR
BICYCLES, TRICYCLES, VELOCIPEDE BOATS, AND SUCH LIKE VEHICLES OR VESSELS "
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :—
In the Specification of my Letters Patent dated the 2nd August 1884 N° 10899
I described a construction of saddle for bicycles and other like vehicles, in which
the leather of the seat is stretched over curved elastic pads at the rear of the
saddle, these pads being held in hollows formed in a bent metal plate which forms
the framing of the saddle. My present invention relates to an improved con-
struction of the saddle frame and of the adjustments for stretching the leather as
I will describe referring to the accompanying drawings. Fig. 1 is a plan of a
saddle according to my present invention, Fig. 2 is a plan looking froin below,
Fig. 3 is a longitudinal section on X X and Fig. 4 is a transverse section on Y Y.
The frame consists of a steel plate from the middle part A of which extend three
arins, one B to the front and two CC radiating towards the rear. The metal of
each of these three arms is bent round so as to form a tube. Within each of the
arms B, C, C, is accommodated a screw b, c c each fitted with a nut D which is
embraced between two collars of a yoke E one of the collars in each case being
fixed to the end of the tube. Thus while the nut D is prevented by the two sides
of the yoke from moving longitudinally, the screw can be made to move in either
direction by turning the nut the one way or the other. The front end of the
leather is rivetted to a tail piece F projecting from the front screw b. The rear
edge of the leather L terminates in tags and beut round a pad G of caoutchouc
or other suitable elastic material which lies in a shallow curved trough H of metal.
The central tag is secured to this trough by a screw, the other tags are
clamped by screw studs M between the metal H and tail pieces N N extending
from the rear screws c c. Vhen by turning the nuts D the screws b c c are caused
to travel outwards, the leather L is thereby stretched to such degree as may be
desired. The tail pieces N N are made with slotted holes through which pass the
studs M to admit of the divergence of the screws c c when they are extended

page_text: radially outwards. The leather L is perforated by numerous holes or slits for
ventilation as shewn in Fig. 1, a number of these holes being preferably arranged
along the marginal bends of the leather, so as to give greater flexibility in those
parts of the saddle.
By employing the three screws b c c each of them inclining upwards from the
middle of the frame, I am enabled not only to regulate the tightness of the
leather L-but also to adjust the slope of the saddle. Thus if I draw back the two
rear screws cc and extend the front screw b, I can raise the front and lower
the rear of the saddle; or, by drawing b back and extending cc I can lower the
front and raise the rear. I can also, by, differently extending the two screws bb,
give the saddle a cant to the one side or the other as may be desired by the rider.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim, in respect of saddles for bicycles and the like, is
1. The construction of frame having three tubular arms provided with screws for
tightening and adjusting the leather, substantially as herein described.
2. Attaching the radiating rear screws to the curved pad frame by studs passing
through slotted holes to admit of divergence, substantially as herein described.
3. In combination with the tubular arms and their tightening screws and nuts
the yokes E for preventing movement of the nuts lengthwise.
Dated this 4th day of February 1885.
