IMPROVEMENTS IN COUNTER-SHAFTS
Year: 1885

page_text: I THOMAS NIGHTINGALE PALMER of 62 Lansdowne Road, Dalston in the County
of Middlesex, Patent Agent do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN COUNTER-SHAFTS a communication to be as follows:-
3J
This invention has relation to counter-shafts and is applicable to all kinds of
machinery where reversible motion is required and where the motive power is
communicated by belting.
The object of the invention is to provide a simple, strong and positive con-
struction, adapted to be used with a single belt, to secure the forward or backward
motion of the counter-shaft.
The invention consists in the construction and novel arrangement of devices as
hereinafter described.
In the accompanying drawing the letters A, B, and C indicate mitre-wheels and
G the casing inclosing them, which is provided with a door. H is the shaft, which
passes through the casing G. D, E and F are three pulleys on the shaft, the
pulley D, however, being placed on the extended hub c of the mitre-wheel C, and
being secured thereto by the key &.
I is a stud or hanger-pin, having a collar r. The horizontal mitre-wheel B turns
on this stud, and engages on one side the mitre-wheel A which is secured to the
shaft H by the key k and on the other side the mitre-wheel C, which turns on said
shaft, but is secured to the pulley D. The stud or hanger-pin I is provided at its
lower end with branch arms, which extend one on each side of the shaft H, and
are connected therewith by means of transverse set-bolts extending through
apertures in the said branch arms. The pulley E is a loose pulley, and is located
between the pulley D and the pulley F, which is secured to the shaft H by the
key Q.
On the shaft H is a collar p, which is designed to reduce the friction between the
pulleys D and E.
A bracket is provided through which the shipping-rod passes and a suitable
handle is provided for the belt shipper. If the backward motion of the shaft is

page_text: designed to be more rapid than its forward movement, this can be accomplished by
the introduction of an extra wheel.
L indicates the sleeve arranged upon the shaft H between the mitre-wheels A
and C, and the said sleeve is provided on its upper horizontal side with vertical
apertures b, which are enlarged at their mouth portion, so that they may readily
receive the oil or other lubricant as it falls from the upper horizontal mitre-wheel, B,
the same being carried to this gear through the engaging vertical mitre-wheels as
shown. Thus it will be seen that when oil or other liquid lubricant is placed in the
box G the vertical gear-wheels therein will convey it to the horizontal engaging
gear-wheel from whence it will fall into the apertures of the sleeve L and be
readily discharged and distributed throughout the main shaft, thereby lubricating
the various parts of the device as well as the gear-wheels within the oil-box. The
oil is placed in the box through the door in the said box.
The operation is as follows: When the belt is on the loose pulley E the other
parts remain at rest. When the shaft is to be revolved forward the belt is shipped
from the pulley E to the pulley F. To reverse the motion the belt is shipped on
the pulley D.

Figure 2 is a side view of the same.
Figure 3 is a transverse sectional view taken through the hanger-pin and
oil-box.
In the drawing, the letters A, B and C indicate mitre-wheels and G the casing
inclosing them, which is provided with a door O. H is the shaft, which passes
through the casing G. D, E and F are three pulleys on the shaft, the pulley D
however, being placed on the extended hub c of the mitre-wheel C and being
secured thereto by the key s.
I is a stud or hanger-pin, having a collar r. The horizontal mitre-wheel B turns
on this stud and engages on one side the mitre-wheel A which is secured to the
shaft H by the key k and on the other side the mitre-wheel C which turns on said
shaft, but is secured to the pulley D. The stud or hanger-pin I is provided at its
lower end with branch arms, which extend one on each side of the shaft H and are
connected therewith by means of the transverse set-bolts a a extending through
apertures in the said branch arms. The pulley E is a loose pulley, and is located
between the pulley D and the pulley F, which is secured to the shaft H by the
key Q.
On the shaft H is a collar p, which is designed to reduce the friction between the
pulleys D and E.
J represents a bracket through which the shipping-rod passes, and h is the
handle of the belt-shipper. If the backward motion of the shaft is designed to be
more rapid than its forward movement, this can be accomplished by the introduction
of an extra wheel.
L indicates the sleeve arranged upon the shaft H between the mitre-wheels A
and C, and the said sleeve is provided on its upper horizontal side with vertical
apertures b, which are enlarged at their mouth portion, so that they may readily
receive the oil or other lubricant as it falls from the upper horizontal mitre-wheel B,
the same being carried to this gear through the engaging vertical mitre-wheels as

page_text: shown. Thus it will be seen that when oil or other liquid lubricant is placed in
the box G the vertical gear wheels therein will convey it to the horizontal engaging
gear wheel, from whence it will fall into the apertures of the sleeve L and be
readily discharged and distributed throughout the main shaft, thereby lubricating
the various parts of the device as well as the gear wheels within the oil-box. The
oil is placed in the box through the door O.
The operation is as follows:-When the belt is on the loose pulley E, the other
parts remain at rest. When the shaft is to be revolved forward, the belt is shipped
from the pulley E to the pulley F. To reverse the motion the belt is shipped on
the pulley D.
I am aware that it is not new to arrange upon a counter-shaft two vertical bevel-
gears to engage a horizontally-suspended bevel-gear, the said shaft having pulleys
adapted to be fixed and allowed to remain loose upon the said shaft, and therefore
do not claim such devices, broadly.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
First. The combination, with the hanger-pin provided with the branch arms,
and means, as described, for connecting the same to the shaft H, of the oil-box,
mitre-gear wheels arranged within the same, and the sleeve L upon the said shaft,
having vertical apertures, whereby the oil may be caught and distributed to various
parts of the shaft after being carried to the upper horizontal gear wheel by the
vertical gear wheels, substantially as specified.
Second. The combination, with the shaft H, carrying the pulleys D, E, and F,
of the oil-box connected with the sleeve of the said shaft by means of the trans-
verse bolts, and the oil-box supported by means of the hanger-pin, substantially as
specified.
