An Improved Brake for Vehicles.
We, JOHN FRANKLIN SHEPARD, 609 Hamlin Street, Jackson, Michigan,
Blacksmith, CORYELL BARTHOLOMEW of 102 East Main Street, Jackson,
Michigan, Merchant and STEPHEN HENRY CARROLL of 126 East Cortland
Street, Jackson, Michigan, all of the United States of America, 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 invention relates to an improved attachment for operating brakes upon
vehicles, and is attached to the "hounds," or under gearing of the vehicle, and
operated in connection with a brake beam or other device for arresting by friction,
the motion of the wheels, and the object of the invention is to secure greater
leverage power in applying the brake, combined with simplicity of cost and
manufacture, and its adaptability for applying to any style of brake.
These objects are attained by the mechanism illustrated in the drawings,
in which,
Fig. 1, shows top view of the device attached to the gearing.
Fig. 2 shows side view of the same.
Fig. 3 shows top and end view of plates between which the attachment is
operated.
Fig. 4 shows top and side view of lever.
Fig. 5 shows top and side view of draw bar.
I is the brake beam extending across the vehicle and carrying the shoes J on its
outer ends. To the center of the beam I is secured the draw bar H which extends
back parallel with the reach K and on its outer end has bolted thereto a rack bar
formed with racks on its opposite edges of a width less than the width of the bar.
E E are plates arranged above and below the rack bar and having central
grooves in which the bar on either side of the teeth work and is closely held.
These plates are fixedly secured to a stationary part of the vehicle and have
pivotally secured at their opposite ends the levers F which are formed with
segmental racks on their inner ends meshing with the racks on the rack bar. The
levers are closely fitted between the plates and thereby held in engagement with
the rack bar.
M is a brake or connecting rod extending from the extension L of the levers F
to the end lever N which is pivoted on the frame or the box of the waggod.
This
lever is provided with a spring catch adapted to engage with the usual segmental
ratchet frame O on the body of the vehicle. The operator moving the lever N
will draw the connecting rod forward rocking the lever F upon its pivot and the
engagement of the segmental racks at its inner end with the rack on the draw-bar H
will draw the brake beam rearwardly, pressing the shoes tightly against the wheels
and thereby brake the vehicle.
