An Improved Castor.
I, JAMES PERCY ERNEST PROUD, of 20 Westmoreland Street, Dublin, Ireland,
late of Fortal Killiney, Co. Dublin, Student Trinity College Dublin Engineering
School, do hereby declare the nature of this invention and in what inanuer the
same is to be performed, to be particularly desenbed and ascertained in and by
the following statement
-
My invention relates to casters for furniture and has for its object to provide a

page_text: caster which is much stronger; less liable to get out of order; neater in appearance
and operates more readily than casters as heretofore constructed.
My improved caster as its wheel mounted on a socket which tuins upon a cone
or pin fixed to the furniture whereby the lateral strain due to the weight carried
by the caster is distributed over a larger surface than in casters as heretofore
constructed
To enable my invention to be fully understood I will describe the same by
eference to the accompanying drawing, in which
Figure 1 is an elevation of a caster adapted to be applied to the legs of
furniture:
Figure 2 is a vertical section; and,
Figure 3 a horizontal section on the line 3-3, Figure 1
Figure 4 is an elevation of the cone or pin upon which the caster turns; and,
Figure 5 is a vertical section of the socket carrying the caster wheel, and,
Figme 6 is a plan of the same
Figure 7 is a vertical section of a caster for attachment to the flat bottom of a
piece of furniture.
a 19 the socket of my caster, and is the caster wheel which is mounted at one
side of the vertical axis of the socket to permit of the caster wheel readily taking
the dnection in which the piece of furniture is being moved in a well known manner,
the said socket being bored out internally to a couical forin, as shewn in Figure 5,
or parallel with a comical (or hemispherical) base, as shewn in Figme 7.
c is the cone or pin which fits accurately within the socket a so that the latter
turns freely thereon. This cone, in the airangement shewn in Figures 1 to 6, 18
made hollow so that it may be fitted on to the leg of a piece of furniture, as shewn
most clearly in Figure 2; whilst in the arrangement shewn in Figure 7 the piu or
cone c is formed with a flange at its upper end which is fixed to the flat bottom of
a piece of furniture With this arrangement it will be understood that the side
strain upon the caster due to the weight of the furniture, instead of being carried
by the surface of a simple pin as heretofore, is carried by a much larger sui face.
In order to prevent the socket from falling off the cone o pin c the latter is
provided with a grooved into which the ends of sciews e, e inserted in the walls of
the socket a project as clearly shewn in Figures 2 and 7.
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
-
A caster in which the wheel of the same is carried by a socket rotating upon a
cone or pin adapted to be fixed upon the furniture, substantially as described.
