Improvements in Brakes.
DAVID HAY CROLL 9, Stanley Road, Watford Herts Inventor do hereby
declare the nature of this invention to be as follows:-
A holder for brakes of velocipeds, motor-cars, and the like.
The brake is retained to any tension and is released automatically.
As on a bycycle a ratchet-bar is simply hooked loosely on to the handle and held
in position by a strap or band.
On this ratchet-bar a holder for the brake-lever travels. The holder is lifted along
with the brake handle, it engages with the ratchet, and holds the lever in any position.
When the weight of the brake is taken off the holder, its own balance causes it to
disengage from the ratchet and it drops to the end of the ratchet-bar.

COMPLETE SPECIFICATION.
Improvements in Brakes.
I, DAVID HAY CROLL, of 9 Stanley Road, Watford, in the County of Hertford,
Inventor, 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 for improvements in holders for brakes and similar levers of vehicles
and the like has for its object to provide a ready means whereby the brake or other
controlling lever can be retained in any position and if desired locked in that position,
and if not locked be easily and instantaneously released.
A lever holder constructed according to this invention consists of a bar suspended
from the fixed support and a rest for the end of the lever fitted to slide on the bar in
such manner that when pressure is applied to the rest the slide nips the bar but falls
down the bar automatically when the bar is released. The bar is pierced with holes
so that the rest can be locked and thus prevent it slipping further down the bar.
In the accompanying drawings which show this invention as applied to the brake
lever of a cycle,
Fig. 1 is a front view of the holder showing it suspended from the handle bar of
the cycle. Fig. 2 is a sectional side elevation of the same showing the rest supporting the
brake lever.
Fig. 3 is a similar view to Fig. 2 showing the rest just after the brake lever has
been raised out of the rest.
Fig. 4 is a similar view to Fig. 2 showing the rest locked in its upper-most position
and thus locking the brake lever.
Fig. 5 is a side view of the handle bar of a cycle fitted with a brake and provided
with the brake holder.

page_text: The corrugated bar a having a hook b at its upper end is hooked over the handle
bar c and is retained by means of an elastic ring d passing at the back of the bar a
and over the upturned ends e, of the hook b. The lower bifurcated end of the bar a
has its two parts turned in opposite directions. The rest g formed of bent sheet
metal as shown is perforated with holes h for the passage of the bar a but the ends f
prevent the rest g from entirely slipping off the bar. It will readily be seen that if
the brake lever be first raised and then the rest g be raised up under it as shown
in Fig. 4 and the brake lever i then released, it will act on the rest sideways and
cause it to nip the corrugated bar a and so hold the lever i in its raised position. If
now the brake lever i be slightly raised out of the rest as shown in Fig. 3, the
rest will slide down the bar a by gravity. Figs. 4 and 5 show the rest locked by
passing the hasp of the lock through one of the holes o in the bar a so that the
brake cannot be released, thus forming an efficient lock for the cycle. When not
in use the lock is carried on the ends e as shown in interrupted lines in Fig. 4.
The holder may be used for holding other levers than brake levers in position for
example the starting lever of a motor car and the action of gravity may be replaced
by a spring. Also the bar may be roughened instead of being corrugated or if not
subject to excessive vibration may be smooth.
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. A holder for levers sliding on a strap or bar and kept in position on the strap
or bar when in operation by the pressure of the lever on the holder.
2. The improved holder substantially as described with reference to the drawings.
