Improvements in and connected with Pedals of Velocipedes.

Improvements in and connected with Pedals of Velocipedes.
I, PHILIP LOUIS RENOUF, Engineer, of the Holford Engineering Works, Perry
Bar, near Birmingham, do hereby declare the nature of this invention to be as
follows:-
Whereas on pedals the centre or barrel of which forms the bearing, the end-
plates are invariably pressed over the ends of the barrel, I form cylindrical pro-
jections on the end-plates & press them into the recesses in the ends of the barrel,
thus keeping the total diameter down. The holes for admission of the pedal pins
are then made much smaller than usual & a more dust-protected & oil-containing
bearing produced without the aid of washers or other supplementary pieces.
Sometimes the outer-end plates are left solid & form the end dustcaps. To obviate
forward slip of the foot I usually provide toe-clips so formed that they can be
attached & adjusted without any additional screw or clamp.
These toeclips
have each a long springy blade or stalk or a pair of such blades or stalks; these are
provided by raising, punching or other means with ratchet like projections. The
stalks are simply forced across the pedal through the side-plates & over the barrel;
the ratchet like projections engage on one or the other of the side plates & afford
any required adjustment. Where the pedals are to he adapted to carry rubber,
felt, leather or other non-metallic foot bars I bend the teeth of the side plates alter-
nately backwards & forwards so as to form an undercut through for the purpose of
containing the bars; the teeth may he left sharp as usual, so that when no supple-
mentary bars are used, a four-row rattrap pedal is produced.
Dated this 20th day of August 1896.
COMPLETE SPECIFICATION.
Improvements in and connected with Pedals of Velooipedes.
1, PHILIP LOUIS RENOUF, Engineer, of the Holford Engineering Works, Perry
Bar, near Birmingham, do hereby declare the nature of this invention and in what
manner the same is to be perforined, to be particularly described and ascertained
in and by the following statement:-
Whereas on pedals the centre or barrel of which forms the bearing, the end-
plates are invariably pressed over the ends of the barrel, I form cylindrical pro-
jections on the end-plates and press these into the recesses in the ends of the
barrel, thus keeping the total diameter down and allowing the foot of the rider to
get closer to the central liue of the pedal. The holes for the admission of the

page_text: pedal pin are then made much smaller than usual & a more dust-protected & oil-
containing bearing produced, without the aid of washers or other supplementary
pieces. Sometimes the outer end-plate is left solid & forms the end dust-cap. To
obviate forward slip of the foot I usually provide toe-clips so formed that they
can be attached & adjusted without any additional screw or clamp. These toe-
clips have each a long springy blade or stalk or a pair of such blades or stalks;
these are provided by raising, pressing, punching or other means with ratchet-like
projections. The stalks are simply forced across the pedals through the side-plates
& over the barrels; the ratchet-like projections engage on one or the other of the
side-plates & afford any required adjustment.
Referring to the drawings: Fig. I shews a complete pedal in section, A being the
pedal-pin, B the adjusting cone acting also as a locknut to fasten the pin to the
crank; C, C are the slide-plates connected to the centre or barrel F (shewn
separately in Fig. 5) by the outer end-plate E and the inuer end-plate 1) shewn
separately in Fig. 4. These end-plates are provided with a projection each, e and d,
turned to fit tightly into the end or bearing recesses of the centre piece F. By this
means the foot of the rider can come closer to the centre of the pedal than if the end
plates were pressed over the centre piece as has been done hitherto and at the
same time these projections in combination with the bearing recesses form internal
grooves or races capable of retaining the lubricating oil. Sometimes the outer
plate E is pierced to allow of admission to the bearings and closed up by a dust
cap G as shewn in Fig. I or in Fig. 2; sometimes however the plate E' is left solid
& forms the closing piece of the bearing, as shown in Fig. 3. In this case the
balls must be placed in the hearings before the pedal body is joined. One end of
the barrel F is preferably provided with a slot or keyway as shewn in Fig. 5 & the
end-plate with a projecting key f, Fig. 4 to fit the above slot or keyway thus
obviating all possibility of the barrel being loosened by turning round. Fig. 6
shews the side elevation of toe-clip II, & Figs. 7 or 8 the plan of the same. The
toe-clip has either one lower blade K Fig. 8 or a pair of lower blades K, K" Fig. 7.
On this part are formed by pressing or otherwise a series of teeth I I, so that on
inserting the blade or blades through the slots usually found in pedal plates and
over the centre or barrel F' as shown in Fig. 6, the clip is mounted securely on the
pedal & prevented from slipping out by the teeth II I engaging with plate C
To shorten the reach of the toe-clip, it is pushed further over the pedal & to lengthen
or detach it the intended part is sprung out of gear with the side plate.
Having now particularly described & ascertained the nature of my said.
Invention, & in what manner the same is to be performed I declare that what I
claim is
1. In pedals for velocipedes, where the pedal-body is composed of more than one
piece, supporting the end plate or plates by projections on the same resting inside
the extremities of the centre piece for the purpose and in the manner substantially
as described.
2. Suspending the centre piece of a pedal over a suitable projection on an end
plate for the purpose and substantially in the manner described.
3. A toe-clip for pedals of velocipedes provided with teeth as shewn and described,
such teeth in combination with the plain slots in the pedal plates affording the sole
means of mounting and adjusting the toe-clip.
4. On toe-clips a series of teeth or similar projections for the purpose described.
