PROVISIONAL SPECIFICATION.
Improvements in Rollers and Guide Pulleys.
I, HUGH MCCOLL, of 31, Hamilton Terrace, Milford Haven, in the County
of Pembroke, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to the manner in which I construct rollers and
guide pulleys for carrying and supporting the guiding or hauling ropes, chains,
cables and for like purposes, the object of my invention being to construct a
simple and substantial and truly balanced roller in an economical manner.
In carrying my invention into effect, I make the body of my roller of metal
in the form of a tube cut from ordinary gas, water or steam, iron or steel
piping, the length of the body being cut from an ordinary piece of tube to suit
the length of roller which is to be constructed. I mount the body or length of
tube thus cut to form the roller upon cast iron or other ends, the ends when of
metal being preferably shrunk into the open ends of the tube. I prefer to form
lips or retaining rings or rib pieces to secure the tube in position, and for
making a solid end to the roller. These ends I form with bosses for receiving
a shaft or spindle, the bosses being made of any desired length, shape and con-
figuration to suit any particular purpose. The spindles may be made fast to the
bosses when it is desired, or they may be arranged so that the rollers may
revolve upon the spindles. I provide for lubrication to the axles or spindles
when the rollers are to run loose upon them by making channels or other oil
passages through the bosses or through the spindles from the outside, for per-
mitting an efficient supply of lubricant being communicated from the outer ends
of the rollers. When forming my rollers of great length, I may arrange for an
intermediate supporting ring or rings between the extreme ends or bosses of the
complete roller, the rings being made either for the shaft or axle to pass freely
through or being made fast or tight upon the axle as may be desired.
Sometimes I attach my tubes to my end flanges by means of screwing the
surface of the entering ends, so as to permit the screwed internal or external
portion of the pipe or body of the roller to enter.
By another system of attachment, I make my tubes to rest upon the end
flanges and I drill holes through them and pass rivets or screws through the
tubes into the flanges or I cut gaps or serrations in the pipes or tube ends to
enter ribs or corresponding serrations formed in the flange ends for ensuring that
the flanges shall be rigidly connected to the tube bodies and that the tube shall
not revolve without the flanges.
I secure my axles to the bosses, when so desired, by keys, cotters, set screws
or by other ordinary means of attachment now employed for like purposes.
I do not limit the application of my invention to the construction of rollers
for any particular purpose, neither do I limit the ends to any particular metal
or material, as I sometimes employ wooden or other material ends having, when
so desired or where necessary, metal bushes or roller bearings within the wooden
or other flanges for wearing purposes.

I HUGH MCCOLL, of 31 Hamilton Terrace, Milford Haven, in the County
of Pembroke, Engineer, 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 :-
This invention has reference to the manner in which I construct rollers and
guide pulleys for carrying and supporting guiding or hauling ropes, chains, cables,
and for like purposes, the object of my invention being to construct a simple,
substantial and truly balanced roller in an economical manner.
In the accompanying sheet of explanatory drawings Figs. 1, 2, 3, & 4, are
sectional elevations of the methods of construction which I prefer to employ.
I make the body A of my roller of metal in the form of a tube cut from
ordinary gas, water, steam, iron, or steel piping the length of the body being
made to suit the desired length of roller which is to be constructed. I mount
the body or barrel A. of tube thus cut to form a roller upon cast iron or other
ends B. C; these ends when of metal being sometimes shrunk into the open ends
of the tube. I prefer to form lips or retaining rings D or rib pieces to secure the
tube in position and for making a solid end to the roller.
I provide these closing end flanges with bosses D' for receiving a shaft or spindle E,
the bosses being made of any desired shape to suit any particular length of bearing it
is desired to provide for the spindle.
The spindles may be made fast or secure to the bosses by means of hexagonal or
other collars formed upon them or by means of any ordinary keys and driving pins
or cotters; or they may be arranged so that the rollers revolve upon the shafts.
I lubricate the axles or bearings by means of ordinary lubricators attached to the
end of the spindles or to the flanges and having oil grooves and passages H formed
through the spindles or within the boss as may be desired.
When making my rollers of great length I sometimes provide intermediate
supports by means of a ring or rings carried upon the shaft in addition to the end
flanges or rings, these intermediate rings being made for the shaft to pass freely
through them or to fit them as may be required.
Sometimes I attach my tubes to my end flanges by means of screwing the surface
of the entering ends to suit a like screwed surface upon the roller. I also drill
holes through the tubes and rivet or screw them to the edges of the flanges.
I may cut gaps or serrations in the pipes or tube ends to enter and engage with like
recesses formed in the flange ends.
Instead of making a barrel from wrought metal I sometimes make it from chilled
cast iron or other metal as shown at F, the ends being plain flanges as at G or
provided with a bush or plug bearing as at J. I sometimes employ wooden ends
for closing the tubes or barrels and for forming the bearings for the spindles.
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. The construction of metal rollers having bodies formed from tube and having
bosses or separate ends or flanges secured to the ends of the tube substantially as
and for the purpose herein before described and as illustrated in the accompanying
drawings.

page_text: 2. The construction of guide or supporting rollers in which independent bearings
or shaft bosses are attached to the ends substantially as hereinbefore described and
as illustrated in the accompanying drawings.
