page_text: Improvements in Standards or L "Pillars for Supporting the
Seats or Saddles of Velocipedes.
I JOHN HARRINGTON of "The Enamel and Cradle Spring Works," Coventry in
the County of Warwick, Manufacturer, do hereby declare the nature of said
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :—
The invention has for its object a novel construction of standard or L pillar for
enabling a seat or saddle to be supported at any required inclination.
For this purpose instead of making the two arms of the L pillar in one piece
I form them in separate pieces and connect them together by means of a suitable
joint in such manner that the horizontal arm can be turned upon the upright and
fixed at any desired angle thereon.
And in order that my said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view of a standard or L pillar constructed according to my
invention.
Figure 2 is a plan thereof..
Figure 3 is an end view looking towards the right hand side of figure 1.
Figure 4 is an opposite end view.
Figure 5 is a vertical transverse section thereof and
Figures 6 and 7 are separate views of parts.
In the various figures of the drawings like parts are marked with similar of
reference.
a represents the vertical arm of the standard or L pillar and b is the horizontal
arm thereof.
These two arms a and b are connected together with capability of movement one
upon the other by means of a bolt 6' passing through the flattened head a¹ of the
arm a and screwing into the corresponding part 6' of the arm b.
The enlarged or flattened part 61 is formed at right angles to the arm b and
at its lower part it is provided with a curved alot 68. A binding screw or set
screw a² is passed through the slot b³ in the head b¹ of the arm band screwed into
the head a¹ of the arm a a washer a³ being interposed between the head of the
bolt or screw a' and the part b¹.
By this construction of standard or L pillar the horizontal arm 6 may be moved
upon the connecting bolt 63, which is virtually a centre or axis of motion, into either
of the positions shown by the dotted lines in Figure 1 or into any position
intermediate thereof where it may be securely clamped by the aid of the binding
screw or set screw a*.

adjusted to and fixed at any required inclination within certain limits.
I would here remark that I do not confine myself to the precise construction of
standard or pillar herein shown and described as such is given merely as an
example of one method in which my invention may be carried into practice and it
is evident that other modes equally efficient may be devised without departing from
the peculiar nature thereof.
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 is
A standard or L" pillar for supporting the seats or saddles of velocipedes
constructed in such manner that the horizontal arm can be turned upon the upright
arm and fixed at any desired inclination thereto substantially as herein shown and
described.
