PROVISIONAL SPECIFICATION.
Improvements in Devices for Supporting and Protecting Rollers of
Salt or the like for Horses or other Animals.
I JOHN JAMES MASON of 3 Scott's Terrace Trafalgar Road Peckham in the
County of Surrey Clerk do hereby declare the nature of this Invention to be as
follows:-
The object of my Invention is to provide a device for supporting and protecting
rollers of salt or the like such as are known as Spratt's Patent Salt Rollers
which device whilst presenting no sharp corners or edges likely to injure the animals
or projecting parts which the animals can sieze and so injure the device also protects
the roller from injury by the weather when used in open situations and means are also
provided by which the roller can be readily removed and replaced.
According to my Invention the device consists of a bracket or hood with flanges
or the like for fixing it in position and having a curved top and front extending
over and in front of the roller in a curve which leaves no sufficient space between
its front edge and the roller to enable the animals to sieze the front edge in their
mouths. The sides extend down so as to cover and protect the roller ends. The
spindle which passes through the roller and forms the axis upon which the roller
rotates in the bracket or hood projects a greater distance from the roller at one
end than at the other. The shorter end is provided with a screw. The roller is put
in place in the bracket or hood by inserting the longer end of the spindle in the
hole or bearing for it in the one side of the bracket, and then it is moved
lengthwise so that the shorter end of the spindle enters the hole or bearing for it
at the other side of the hood or bracket. A screw nut or cap is then screwed
onto the screw of the shorter end of the spindle and secures the roller in place,
the said nut or cap preferably having a reduced part at its inward portion to form
a journal entering the hole or bearing of the bracket.
When the cap or nut is unscrewed the roller can be moved slightly in the
direction of its length until the shorter end of the spindle leaves its bearing
and the roller can be at once removed. The screws are preferably made in such
a direction that they are not loosened as the roller is rotated by the animals
using them.

Improvements in Devices for Supporting and Protecting Rollers of
Salt or the like for Horses or other Animals.
I, JOHN JAMES MASON of 3 Scott's Terrace, Trafalgar Road, Peckham in the
County of Surrey, Clerk, 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
which
The object of my Invention is to provide a device for supporting and protecting
rollers of salt or the like such as are known as "Spratt's Patent Salt Rollers
device whilst presenting no sharp corners or edges likely to injure the animals nor
projecting parts which the animals can seize and so injure the device, also protects the
roller from injury by the weather when used in open situations and means are also
provided by which the roller can be readily removed and replaced.

page_text: I will describe my invention with reference to the accompanying drawings Figure 1
being a perspective view, Figure 2 a front elevation, Figure 3 an end view and
Figure 4 a plan of a device according to my invention.
The device consists of a bracket or hood A with flanges a or the like for fixing it in
position against a wall or other support and having a curved top and front as shown
at 6 extending over and in front of the roller B in a curve so as not to leave sufficient
space between the front edge of the hood and the roller to permit of the animals
seizing the front edge of the hood in their mouths. The sides of the hood extend
down so as to cover and protect the roller ends. The spindle which passes through
the roller and forms the axis upon which it rotates in the bracket or hood A projects
to a greater distance from the roller at one end d than at the other end d². The end d²
of the spindle is provided with a screw thread. The roller B is put in place in the
bracket or bood A by inserting the longer end d of the spindle in the hole or bearing
for it in the one side of the bracket and then it is moved lengthwise so that the shorter
end of the spindle enters the hole or bearing for it at the other side of the hood or
bracket. A screw nut e or cap is then screwed onto the screw of the shorter end d² of
the spindle and secures the roller in place, the said nut or cap preferably having a
reduced part at its inward portion to form a journal to work in the hole or bearing in
the side of the bracket. The roller may be readily removed from the hood A by
unscrewing the cap or nut e and then moving the roller slightly in the direction
of its length until the shorter end of the spindle leaves its bearing.
The screw on the spindle is preferably inade in such a direction that the nut
or cap will not be loosened when the roller is rotated by the animals using it.
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
1st. A device for supporting and protecting from injury rollers of salt or the like
for the use of horses and other animals consisting of a bracket or hood having no sharp
corners nor edges likely to injure the animals, and no projecting parts which the
animals can seize, substantially as hereinbefore described with reference to the
accompanying drawings.
2nd. In means for supporting and protecting from injury rollers of salt or the like
for the use of horses and other animals, providing the roller with a spindle arranged
to project further from one end of the roller than it does from the opposite end
thereof, the shorter projecting end of the spindle having a screw thread thereon for
the reception of a nut or cap to secure the roller in its bearings in the hood or bracket
and whereby the roller may be readily placed in position and removed substantially as
herein before described with reference to the accompanying drawings.
3rd. The general construction and combination of parts constituting a device for
supporting and protecting from injury rollers of salt or the like for the use of horses
and other animals substantially as herein before described and illustrated by the
accompanying drawings.
