Improvements in Levelling Devices for use in connection with
Billiard or like Tables, or other heavy Furniture.
We, JOHN WILLIAM ROCHE, of No. 341, Kearny Avenue, in the Town of Kearny,
County of Hudson, and State of New Jersey, Inventor, and JOHN BERNS, of
No. 119, Johnson Avenue, in the said Town of Kearny, County of Hudson, and
State of New Jersey, Machinist, both in the United States of America, do hereby
declare the nature of our invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention has reference to a novel device to be used under the leg of a
billiard or pool table, or other heavy furniture, for the support of the same, when
arranged upon uneven flooring, and certain parts of the device being capable of
vertical adjustment, and other parts being capable of a rocking or oscillatory
motion, whereby the piece of furniture can be placed in a perfectly level condition
upon the floor.
The primary object of this invention therefore is to provide a device for the
support, more especially, of heavy furniture, the parts of the device being capable
of quick and easy adjustment to cause the piece of furniture to set perfectly level.
The invention consists in the novel construction of leveling device hereinafter
fully set forth, and also in the novel arrangements and combinations of the parts
thereof, such as will be clearly described in the accompanying specification and
finally embodied in the clauses of the claim
The invention is illustrated in the accompanying drawings, in which:-
Figure 1 is a side view of our novel construction of leveling device, illustrating
its application to the leg of a billiard table.
Figure 2 is a longitudinal vertical section of the device, on an enlarged scale ;
and Figure 3 is a top view of the same.
Similar letters of reference are employed in all of the above described views,
to indicate corresponding parts.
In said drawings, A indicates the complete device, which comprises a base-
plate a provided with suitably arranged points a¹ for holding said plate to the
floor, and preventing its turning or slipping thereon, when the device is operated.
As will be seen from Figure 2, said plate or base a has a central and tubular
post a³, which is provided with an internal screw-thread a³.
Into this screw-threaded post a³, is screwed the downwardly extending and
screw-threaded portion a' of an upper plate or cap a5, which has an annular rim a6
provided with suitably disposed holes a', or other suitable means, for the reception
of a wrench, to raise or lower said cap upon the post a³, as may be desired.
In the upper part of said screw-threaded portion a' is a socket as adapted to
receive a pivotal support or post 6 of a suitable plate b adapted to be placed
beneath the leg of a piece of furniture.
The action of the several parts of this construction of the device and its advan-
tages will be evident from an inspection of said Figure 2, there being very little

page_text: friction between the rotating parts, and the pivotal plate b, by its arrangement
in the socket as having a rocking or oscillatory motion, will permit of the table
or other piece of furniture supported thereon, in many instances, to be set level
without previous adjustment of the plate or cap as upon the post a² of the base a.
As shown, said plate 6 may be provided with small holding points 63, but these
points may be dispensed with, if desired.
It will be evident, that the device herein shown is of a very simple construction
and perfectly operative to raise or lower the end of a heavy table or other piece
of furniture and cause the same to set perfectly level upon an uneven floor.
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:-
1. A leveling device, for the purposes stated, comprising a base adapted to be
arranged upon the floor, a cap rotatively arranged on said base and vertically
adjustable thereon, and a socket as in said cap, and a plate b having a post b¹
adapted to fit in said socket, for supporting said plate on said cap so that it may
rock or oscillate, substantially as and for the purposes set forth.
2. A leveling device, for the purposes stated, comprising a base adapted to be
placed upon the floor, having an upwardly extending tubular portion provided
with an internal screw-thread, a cap rotatively arranged on said screw-threaded
portion and vertically adjustable thereon, and a socket as in said cap, and a plate b
having a post 61 adapted to fit in said socket, for pivotally supporting said plate
upon said cap so that it may rock or oscillate, substantially as and for the purposes
set forth.
3. The herein described leveling device, comprising a base a having points a¹,
and a tubular post a² provided with an internal screw-thread, a cap a³, having an
annular flange a, provided with holes a, a screw-threaded portion a vertically
adjustable in said post a², said portion at having a socket a8, and a plate 6 having
a post adapted to fit in said socket, whereby said plate b is pivotally arranged
so that it may rock or oscillate, substantially as and for the purposes set forth.
4. The herein described leveling device, comprising a base a having points a¹,
and a tubular post a² provided with an internal screw-thread, a cap a³, having an
annular flange a, provided with holes a, a screw-threaded portion a vertically
adjustable in said post a², said portion at having a socket a8, and a plate b having
a post adapted to fit in said socket, whereby said plate bis pivotally arranged
so that it may rock or oscillate, and said plate 6 being provided with pins 62, sub-
stantially as and for the purposes set forth.
