An Improved Joint for Turnover Covers on Soup Dishes, Butter
Dishes, Biscuit Boxes, Spirit Frames, and the like.
I, JOIN NEWTON, 74 Woodstock Road, Sharrow, Sheffield, in the County of
York, Assay Warden, do hereby declare the nature of this invention to be as
follows:
My invention relates to improvements in the joints of turnover Covers for Soup
Tureens, Biscuit boxes and other revolving or semi-revolving covers or parta of
like receptacles, the object being to automatically control the movement of the
cover and counteract the effect of gravitation by an elastic resistance. In carry-
ing out my invention as applied to a Soup Tureen (for example) having a semi-
revolving motion upon two short axes, 1 construct the joints as follows:
The axis or joint pin upon which the cover is supported and upon which it
turns, is carried in a tubular bearing fixed upon the edge of the dishi at each side,
and after passing through the joint piece of the cover it enters a second bearing
outside the said joint piece. It is prevented from turning round by a projection
engaging with a groove or an open slot made in the tubular bearing.
The part of the joint pin which is held in the bearing, is of larger diameter
than that upon which the cover turns, thus forming a shoulder which abuts
against the side of the cover joint piece, and between these two surfaces, frictional
contact is produced by the action of a coiled spring, placed at the back of the
pin within the bearing, and secured by a screw-on cap, by which the requisite
resistance is obtained.
Where it is necessary to dispense with the second bearing above described, a
modification of the above arrangement is necessary.
In this case instead of the joint of the cover turning upon a pin, the pin is
formed upon it, and passes through a short sleeve or collar, friction being set up
between them by means of a coiled spring held between the opposite end of the
sleeve, and a nut screwed upon the extreme end of the pin.
A projection upon the outside of the sleeve, fitting into a recess within the
tubular bearing, prevents it revolving with cover.
For ease of manufacture I prefer to make the tubular bearing in two parts,
dividing it longitudinally, and securing them by means of a screw cap.

I, JOHN NEWTON, 74 Woodstock Road, Sharrow, Sheffield, in the County of
York, Assay Warden, do hereby declare the nature of this invention and in what
manner the same has to be performed, to be particularly described and ascertained
in and by the following statement :--
My invention relates to improvements in the construction of the joints of turn-
over covers for Soup Tureens, Biscuit boxes, and other receptacles having revolv-
ing or semi-revolving covers or lids the object being to automatically control and
regulate the movement of such covers or lids by counteracting the effect of gravita-
tion by means of elastic frictional resistance.
The accompanying drawings illustrate two methods of constructing my improved
joint.
Fig. 1, is an elevation of a complete joint made on the plan which I prefer.
Fig. 2, The axis and sleeve.
Fig. 3, The coiled spring.
Fig. 4, The two parts of the tubular bearing.
Fig. 5, Elevation (part in section) and end view of a joint with double hearings.
In carrying out my invention as illustrated in Figs. 1, 2, 3, 4, being a joint with
a single bearing, I construct a tubular bearing A, Figs. 1 & 4, which is afterwards
secured upon the edge of the dish D, or other receptacle, for facility of manu-
facture I prefer to make this bearing in two parts, the division A being longi-
tudinal.
In one part I make a groove or keyway B, and the outer end C, is screwthreaded
to receive a cap E, which is correspondingly threaded and holds the two parts
firmly together.
The axis F, Fig. 2, is made with a head or joint-piece G, to which the revolving
cover is affixed, as indicated at II, upon the axis F, I fit a short sleeve I, pro-
vided with a key or like projection J, to fit into the keyway B, by which arrange-
ment it is prevented turning round in the bearing.
Upon the exposed part of the axis marked F, I pass a coiled spring K, Fig. 3,
and adjust the tension or pressure against the sleeve by the regulating nut L,
and thus frictional resistance to the rotary movement of the axis which carries the
cover is set up between the joint piece G, and the sleeve I, which is held by the
key J, and is forced against G by the spring K.
One of these joints is secured to each of the opposite sides of the dish, and also
to the cover, as will be well understood by the trade.
The double bearing joint shown in Fig. 5, preferred by some makers, embodies
the same principle.
The parts A, and M, are affixed to the dish and form the double support to the
pin or axis F, upon which the cover H, revolvos. The pin F, is provided with a
central enlarged part I, upon which is a key J, which enters a koyway in the
part A, a coiled spring K, encircles the opposite end of F, and is regulated by
ineans of the screw cap E.
The action of the spring presses the face of I, against the part II, and that
against M, causing frictional resistance to the movement of H.
I do not bind myself to the design shown nor to the proportions as these may
be varied, but;

page_text: 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 I
claim is:-
1. The improved spring controlled friction joint for turnover covers and the like
as hereinbefore described and as shown in Figs. 1, 2, 3, and 4 of the annexed
drawings.
2. The improved spring controlled friction joint for turnover covers and the like,
as hereinbefore described and as shown in Fig. 5, of the annexed drawinga.
3. A joint for the turnover covers of receptacles having a bearing A, axis F,
sleeve I, regulating spring K, and cap E, constructed, arranged and acting together
us herein before described and shown.
