I WALTER BRAMPTON of the Firm of Brampton Brothers, Oliver Street
Birmingham in the County of Warwick, Manufacturers do hereby declare the
nature of my said invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
My invention has for its object improvements in saddles for cycles and other
such like purposes and relates in particular to the construction of the boss at the
underside of the saddle which embraces the under frame of the saddle and also holds
the bar and is capable of adjustment upon the frame. This invention is really
an improvement in detail upon my previous Patent No. 16899 A.D. 1895 and
refers to the formation of the boss B mentioned therein.
In order that my invention may be clearly understood and more easily carried
into practical effect I have appended hereunto a sheet of drawings upon which
the boss B is clearly illustrated in connection with the underframe A. It must
however be understood that the boss as shown may be applied to saddles of various
builds and designs and to those built upon springs.
Figure 1 is a side elevation of a portion of the underframe A showing the boss B
mounted in the said frame, the figures A and B referring to the same parts in the
specification as in my previous patent herein before mentioned but the frame A is
simply shown to make clear the connection, my present invention merely referring
to the particular construction of the boss B in reference thereto.
Figure 2 shows a metal stamping in plan as it comes from the stamping dies
and before it is bent or worked round into the shape shown in side elevation at
Figure 1.
Figure 3 shows a metal stamping in plan similar to that illustrated by Fig. 2
but modified in the details as hereafter to be more fully explained.
Figure 4 is an end view of the boss B with the letter N representing the
position the bar N would take and as shown in the specification of my previous
patent hereinbefore referred to.
In the case of my previous patent the curved grooves 6³, ³ are formed out of the
solid metal as a continuous groove and have to be machined with a circular cutter
the whole length of the said grooves or they must be otherwise so manipulated or
worked so as to fit the sides of the frame A. A. accurately which causes considerable
expense and time and tools. Now according to my present invention the projecting
parts 64 and 67 are so formed that the ends 6, 65 and 66, 66 only bear against the
side frame A the intermediate part standing quite clear of the frame A so that the
circular cutting tool has only to operate upon a very greatly reduced surface
on each side the groove b³ thus saving much time and cost in the renewal of the
tools.
The modification shown by Figure 3 only varies from Figure 2 in that the
shoulders or bearing portions 65 and 66 66 are simply projecting studs solid with the
stamping B or they may be tapped in as separate pieces but I prefer to make them
solid with the stamping but they may of course be square or other shape other than
round as shown. The parts 68 and 59 are hollow spaces and do not touch the slides
or frame A

page_text: 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 :-
In saddles for cycles and other such like purposes the particular construction
of the adjustable boss B so that the bearing parts 65 and 66 constitute and
establish the groove for the purpose of ensuring a bearing against the frame
bars A and to reduce the cost of construction and weight of this particular part
substantially as herein set forth and as shown upon the accompanying sheet of
drawings.
