Improvements in Shafts for Vehicles.
I, WILLIAM JOHN POHRER, of 2757 Gravois Avenue, St. Louis, Missouri,
U.S.A., Physician and Surgeon, 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 :-
My invention relates to improvements in "shafts," or more especially safety
shafts and consists in the novel arrangement and combination of parts as will be
more fully hereinafter designated in the claims :
In the drawings :
Fig. 1, is a perspective view of my invention.
Fig. 2, is a longitudinal section of one of the shafts with parts broken away,
especially designed to show the bi-sectional construction of the same.
:
Fig. 3, is a cross section of the cross pieces uniting the shafts taken medianly
through said cross pieces.
The object of my invention is to construct safety shafts for the use of vehicles.
The same being so constructed that when an animal is hitched to said shafts and
becomes frightened the driver may readily disconnect the sections of said shafts
and release the animal from the vehicle thus preventing any injury to said vehicle
or its occupants.
In order to achieve this end I employ bi-sectional shafts, the rear sections
whereof being united to the front axle of the vehicle in any desirable and mechanical
manner and the front sections or the sections to which the animal is hitched being
united to said rear section and adapted to be readily disconnected by the driver, in
a manner as will be more fully hereinafter described.
Referring to the drawings:
1, indicates the shafts which are similar in construction and are exact duplicates
of each other.
Said shaft 1, is composed of two sections-the rear section 2, and the front
section 3, or in other words said shaft is bi-sectional.
The rear sections 2, are secured to the axle of the vehicle in any well known
and desirable manner, and are connected together by means of a cross piece 4,
made of wood or any other desirable material.
The front sections 3, are secured or fastened together by means of a cross piece 5,
in any suitable and mechanical manner.
Secured to the center of said cross piece 5, is an elastic plate 6, the same being
provided or that is, carrying a ring 7, and a pin 8 (see Figs. 1, and 3 for illustra-
tion).
Mounted on the cross piece 5, in any suitable and mechanical manner is a single
tree 9, of the usual construction and also employed for the usual purpose.
10, indicates an iron socket or hole which is formed in the cross piece 4, and in
which the pin 8, is adapted to snugly fit and is held therein by the elasticity of the
plate 6, it being noted in this connection that the plate 6, is approximately
S-shaped.
Mounted on the sections 2, of the shafts and secured thereto by means of
pins 11, or in any other suitable and mechanical manner are cylindrical sleeves or
collars 12.
The sleeves 12, are securely and substantially secured to the sections 2.
13, indicates eyes which are secured to or cast integrally with the sleeves 12, for
the purpose more fully hereinafter described.
Secured to the lower surfaces of the sections 3, and projecting beyond the rear
Di

page_text: ends of the same are plates 14, the rear ends of which are adapted to pass through
and snugly fit in the eyes 13, as illustrated in Fig. 1.
The rear ends of the sections 3, are adapted to fit in the sleeves 12, but may be
readily placed in or withdrawn from the same, and also the plates 14 may be readily
placed in and withdrawn from the eyes 13.
Secured to the ring 7, is a rope, wire or rod 15, which may be manipulated by
the driver.
Having given a mechanical description of the construction of my invention; as
well as briefly stated its object, I will now proceed to describe the operation of the
same.
Conceive the shafts to be made and put together as described and the animal
hitched to the same in the usual manner (it being prefaced that the shafts are
secured to a vehicle), and also imagining the animal to become frightened-the
driver by pulling on the cord 15, and lifting the pin 8, out of its appropriate
socket the sections 3 will then be disconnected from the sections 2, secured to the
vehicle and thus the animal may flee released from said vehicle.
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. Bi-sectional shafts for vehicles adapted to be disconnected from the vehicle,
substantially as set forth.
2. Bi-sectional shafts for vehicles, sleeves or sockets mounted on the rear sections
of said shafts in which the front sections are adapted to fit, a spring plate provided
with a pin or similar device carried by the front section of said shafts and adapted
to engage with and be disengaged from a socket carried by the rear sections of
said shafts, substantially as set forth.
3. Safety shafts for vehicles composed of sections, a cross piece such as 4, for
connecting the rear sections, a similar cross picce such as 5, for connecting the
front sections, sleeves 12, mounted on the rear sections, an elastic plate 6, carrying
a pin 8, adapted to engage said cross piece 4, and means adapted to be manipulated
from the vehicle for disengaging said pin, substantially as set forth.
4. Safety shafts for vehicles composed of sections, a cross piece such as 4, for
connecting the rear sections, a similar cross piece such as 5, for connecting the
front sections, sleeves 12, mounted on the rear sections, means for connecting and
holding the front and rear sections substantially together, and means adapted to be
manipulated from the vehicle for disconnecting the front sections, substantially as
set forth.
5. Safety shafts for vehicles composed of sections, a cross piece such as 4, for
connecting the rear sections, a similar cross piece such as 5, for connecting the front
sections, sleeves or sockets 12, mounted on the rear sections adapted to receive the
rear ends of the front sections, an elastic plate 6, carrying a ring 7, and pin 8,
the latter adapted to engage said cross piece 4, and a cord, wire or similar device
for disengaging said pin, substantially as set forth.
6. Safety shafts for vehicles composed of sections, the front and rear sections
being suitably united, sleeves 12, provided with eyes 13, mounted on the rear
sections, said eyes adapted to receive plates or bars 14 carried by the front sections,
an elastic plate 6 carrying a pin 8 adapted to fit into a socket 10 formed in the
connecting piece of the rear sections, and a cord 15, for disengaging said pin,
substantially as set forth.
