PROVISIONAL SPECIFICATION.
An Improved Pedal or Treadle for Velocipedes and Light Machinery.
I, DANIEL PEGLAW of Division Street, Buffalo, New York State, United
States of America, Mechanic, do hereby declare the nature of this invention to be
as follows:-
The object of this invention is to produce a treadle of light construction and
operation for velocipedes generally and for light machinery and which will be
interchangeable and capable of use at either side of the velocipede. The treadle
or pedal consists of a frame having horizontal top and bottom plates, transversely
bored vertical end pieces connecting said plates and a central vertical plate
connecting and bracing them. This vertical plate is bored and grooved to receive
balls forming the bearing for the pedal supporting shaft which is secured in the
vertical plate by means of a nut and washer. In this construction only a single
central ball bearing is employed as a support for the pedal or treadle as distinguished
from the usual double bearing.

An Improved Pedal or Treadle for Velocipedes and Light Machinery.
I, DANIEL PEGLAW of Division Street, Buffalo, New York State, United
States of America, Mechanic, 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 :-
The design of this invention is to provide a treadle for velocipedes generally, and
for light machinery, whereby less material than is customary is employed in the
construction, the treadle or pedal is lighter and a single central ball bearing
support given to the treadle or pedal in contradistinction to a double bearing, one
at each end, and whereby said treadles or pedals and their supporting shafts are
interchangeable and capable of use at either side of the velocipede.

piece with the frame or separate and attached thereto by screws or other suitable
means. Similarly the counterbalance 2 may be in one piece with, or separate, and
secured to the frame 1. Where the frame 1 is solely adapted for a rat trap pedal

with the tread, but where desired said ends 4 may be cast or otherwise formed with

be journalled. It will thus be seen that my improved treadle may be used
interchangeably in connection with either rat trap or rotary rubber treads.
Instead of a metal tread plate 3, or suitably attached thereto, a strip of rubber
may be employed upon which the foot of the operator may rest. The end plates 4
have openings 8, through which the treadle or pedal supporting shaft may be passed
on to the central bearing.
10 is the central bearing frame for the treadle shaft 9. This frame may be in
one piece with or separate from and attached to the frame 1. When separate it is
formed at top and bottom with outwardly extending flanges 11 rivetted or otherwise
secured to the top and bottom longitudinal plates 12 of frame 1. The central
bearing frame 10 has a central bore 13 to receive the treadle shaft and in the bore
a recess 14 to receive and hold the balls 15 constituting with the cone 16, the ball
bearing. By forming the circumferential recess U shaped in cross section, the
balls are securely retained in position without interfering with their operative
qualities. The shaft 9 is threaded at each end, thread 17 serving to connect with
the crank of the wheel (not shewn) and thread 18 at the other end to receive the
cone 16 and cone retaining nut 19. 19 is a washer placed between the cone 16
and nut 19. 20 is a stop collar with flat edges for wrench grips. 22 a collar on
shaft 9 which abuts against the central bearing frame 10 and serves to insure the
correct position of said shaft, the collar being formed at its inner end with a
bevelled face 23 which within the bore 13 comes in contact with the inner end of
the cone so as to form with the bevel of said cone a frictionless bearing for the
balls 15. The outer end of the cone 16 may have either Hat wrench gripping faces
or it may be milled.
It will be obvious that my treadle is adapted for use in connection with
velocipedes of every description and that it can equally well be employed in
connection with other mechanism in which pedals are used or required.
By arranging the bearing frame in the middle of the pedal frame this latter is
additionally braced.
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 1
claim is―
1. A treadle composed of a frame having horizontal top and bottom plates,
transversely bored vertical end pieces connecting said top and bottom plates, and a
central vertical frame connecting and bracing said top and bottom plates and
having a circumferentially grooved ball receiving bore, a treadle supporting shaft
connected at one end with the customary crank and at its other end having bearing
in the central frame, a cone consisting of a bevel ended stop collar secured to said
shaft and a bevel ended nut adjustable on said shaft, and friction balls contained
within said grooved bore, substantially as described and shewn.
2. A treadle composed of a frame having vertical end pieces with transverse
openings, and longitudinal top and bottom plates, a central bearing connected with
said top and bottom plates and having a central bore provided with a circum-
ferential ball receiving recess of U shape in cross section, balls contained within
said recess, a treadle supporting shaft extending from one end of said frame to the
central bearing therein, and having a bevel ended stop collar and a cone and cone
clamping nut mounted on said shaft, substantially as described and shewn.
