COMPLETE SPECIFICATION.
Improvements in Casters for Furniture.
We, KARL AUGUST KLOSE, and WILLIAM KOUNTZ SEWARD, Manufacturers,
both of Butte, County of Silverbow, and State of Montana, United States of
America 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 :-
Our invention relates to improvements in casters for furniture, and it consists
in the advantageous construction, novel combination and adaptation of parts
hereafter described and particularly pointed out in the claim appended.
In the accompanying drawing:
Fig. 1, is a perspective view of our improved caster.
Fig. 2, is a vertical section, partly in elevation, illustrating the caster as
connected to the leg of a piece of furniture, and:
Fig. 3, is a horizontal section taken in the plane indicated by the line a, a, of
Figure 2, with the small balls shown in plan.
Referring by letter to the said drawing:
A, indicates a leg of a piece of furniture, with a socket a, flared and rounded
at b; and B, indicates the shank of our improved caster.
This shank has a cup c,
formed on it which conforms to and is seated in the mouth b, of the socket and
said shank is also provided with the integral flange d, which bears against the
leg A, and extends inwardly to form a ledge e. Said shank B, has a depending
annular flange F, preferably flared as shown.
Arranged within the cup b, and above the ledge e, are four anti-friction balls C,
against which bears a large ball D, which also bears upon the floor as shown.
This large ball is retained in position by the concavo-convex cap E, which has a
central aperture g, of less diameter than the ball D, through which said ball
extends as shown.
The cap E, has a flange h, and this flange together with the flange d, of the
shank portion B, is provided with apertures i, for the passage of screws which
connect the cap E, and the shank portion B, and also connect the caster to the
leg A.
In assembling the parts of our improved caster, the small balls C, are placed
in the cup c, and the large ball D, is placed within the annular flange F, and
against the small balls as shown, after which the cap E, is placed over the large
ball and connected with the shank portion B, in the manner described. From this
it will be seen that the parts of the caster may be quickly and easily assembled
and also that the caster may be very easily connected to the leg of a piece of
furniture.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
A caster comprising the shank portion having the cup c, and also having the
ledge e, extending inwardly from the edge of the cup and the annular flange /
depending from said ledge, the plurality of balls C, arranged within the cup e,
and bearing against the interior of the same and the ledge e, and also bearing

page_text: against each other; said balls C; being free to race or move around upon the
ledge
and the large ball D, arranged within the flange f, of the shank portion
and bearing against the balls C; substantially as and for the purpose set forth.
