1, THOMAS JENNER of Lebonah, Rochester in the County of Kent, Brewery
Manager, do hereby declare the nature of this invention to be as follows:-
Within the holder tube or other enclosing part of the holder I provide two or
more, but preferably three, dises or rings made of metal, wood or other suitable
material, the middle ring or all three being in some cases made of insulite, a soft
metal alloy or the like for exerting a soft grip upon the article to be held.
Through these dises is formed a hole bored eccentrically to the circumference.
The top and bottom rings are attached to the holder tube while the middle ring
can be made to turn by hand and may for this purpose be formed with a inilled
edge or with a knob or knobs or other projections protruding through a slot or
slots or openings in the holder tube. For entire rings I may in some cases
substitute segments. The lead pencil, carbon rod, flower, bouquet, candle, needle
or other part or article having been inserted through the holes in the three dises
while the middle ring is fair with the other two is held or gripped tightly or more
or less so as desired by turning the middle ring partly round.
In flower holders and the like I preferably form the upper ring in the tube or
holder proper with dish-shaped upper surface or bevel the edge of the hole to
make the flower stalk enter readily or I may bevel all the inner edges of the rings
to avoid injury to the flower or other object held. The outer tube or water vessel
(wherein the aforesaid inner tube or holder proper can be slided up and down with
a little holding friction aided or not by a nipping spring) is held in the board or
foundation by a ring with a flange, rotatable in a circular recess therein and
provided with eccentric hole through which the water vessel passes and is held at
any desired height by turning the ring partly round; this ring being comparatively
deep suffices in this case to hold the water vessel between it and the hole in the
lower part of the board so that I can dispense with the third ring. Sometimes I
provide stops for determining the fully open position of the discs or the arc of
rotation and this may be done by the length of a slot in the outer case or in a
Hange in the outer vessel or by making the discs or segments indented into each
other with freedom to rotate to the required extent.
In risers for bicycle seats I may provide grooves or milling in the inner surface
of opening in the middle ring and a corresponding grooving of the rod of the
saddle support. Or I may provide similar grooving in the upper and lower rings
instead, or in all three rings.
The invention is applicable to many other holding appliances and will have to
be modified in some cases to suit the requirements.
Dated this 25th day of June 1894.

1. THOMAS JESSER of Lebonah, Rochester, in the County of Kent, Brewery
Manager, 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 :-
Within the holder tube or other enclosing part of the holder 1 provide two or
more discs or rings such for instance as the rings a, b and c in the sectional elevation
Fig. I made of metal, wood or other suitable material. The middle ring & or all
three rings are in some cases made of insulite or a soft metal alloy or the like for
exerting a soft grip upon the article d to be held. Through these dises is formed
a bule bored eccentrically to the circumference as shewn in the plan section Fig. 2.
The eccentricity is in this and the following cases shewn exaggerated for the sake
of clearness The top ringa und the bottom ring are attached to the holder
tube or either or both of them made in one piece therewith while the middle
ring can be made to turn by hand and may for this purpose be formed with a
milled edge as shown on one side in Fig. 1 or with a knob as shewn on the other
side in dotted lines, or knobs or other projections or handles protrading through a
slot or slots el ur openings in the holder tube. When a cover ƒ is provided one of
the rings a or b, or both of them may be omitted; in Fig. 3 is shewn the latter
arrangement. In both cases the ring is turned in one direction or the other for
gripping or for rebensing the article'd, by means of the thumb and finger applied
to the two opposite sides of the ring or by the thumb and finger applied to the
knob. The parts a band Fig. 1 need not be entire circular discs, but may
form portions of same as may in each case be needful.
r
Fig. 4 is a vertical section through a flower holder. The upper ringa is fixed
in the tube or holder proper e: the upper surface of this ring is by prefere see
formed dish shape or with bevelled inner edge to make the flower stalk bouquet
enter readily. The bottom ringe is also fixed in the holder e The middle ring b
is free to turn and is for this purpose formed milled, grooved or roughened outside,
the slots being provided for taking hold of it by finger and thumb; or it might
be provided with a knob or knobs like Fig. 1. All the inner eiges of the
rings a, and may he hevelled to avoid injury to the flower or other object held.
y is an outer tube or water vessel wherein the tube or holder e can be sliled up
and down with a little holding friction aided or not by a nipping spring or by a
gripping appliance made according to this invention. This water vessel is held
on the board, flower stand or founaation & be a ring 4 with a flange rotatable in a
circular recess therein auf provided with eccentric hole through which the water
vessel y passes, into a hole in the board & which hole is bored excentric to the
recess for the ring and is held at any desired height by turning the ring partly
round; this ring being comparatively deep suffires in this case to hold the vessel
between it and the hole in the tower part of the board so that I can dispense with
what would answer to the ring a. Sometimes I provide stops for determining and
indicating the fully open position of the discs or the are of rotation, and this may
be done by the length of the slut in the outer case, or in a flange in the tube e or
outer vessel g, or by making the discs or segments indented into each other with
freedom to rotate to the required extent." is a stop which works in a part

be in the shape of a flower stand board provided with one or more flower
holders e, g, but may form part of a vase wherein the vessel is partly
concealed.

standard connection between the carbon holder and the frame of the lamp. This
handle and the ring are by preference made of or covered with asbestos, insulite
or other nonconductor. Fig. 7 shows the position of release and Fig. 8 in an
exaggerated form the position of gripping the carbon d.
Figure 9 shews a needle bar of a sewing machine. The lower end of this needle
bar is formed like the upper end of the candlestick Figure 5. The body of the
needle bare has a recess which contains the ring, the latter being held therein
by the ring or cap d.
The needle d has a conical end which bottoms in the recess
and is formed as usual with a flat or feather to ensure its right position.
Figure 10 is a longitudinal and Figure 11 a cross section through a grip for a
cable such as is used for hauling trucks in mines and other places. The rings a
and are made in halves (see the detail sectional view Figure 1A) one half fixed
to the one half of the tube e and the other half to the other half of the said tube
these tube halves being hinged together and held together by rings at each end.
The ring has a lateral slot for entering the cable see Figure 11. By means of
the lever handle the ring can be turned to grip or release the cable d. By
suitable bell-crank connections between the lever and the thin broad gripper
holder now used for endless cable traction for streets my invention can be applied
to such tramways, where the said thin holder works through a inch wide slot
between the rails. This form of grip holder is also applicable to ropes on board
ship and elsewhere, submarine telegraph cables, for the purpose of gripping the
same during paying out for the automatic checking of lifts cages and other similar
purposes.
Figures 12 and 13 are longitudinal section and end view of a door handle. The
knobe has a central hole which is round at the inner end and square at the outer.
The knob has a boss, eccentric thereto and upon this hoss is placed the ring b
having a recess eccentric to the circumference and broken through in the form
of a slot at the outside. The stem d is round at one end and square for the
rest of its length. It is formed with notches on one or more corners and when
the ring has been turned so that the edge of its slot fits into one or
these notches, which is the right one for the thickness of the door, then the ring
is in position for being fixed by means of a set screw m.
two of
In risers for cycle seats provide grooves or milling in the inner surface of
opening in the middle ring and a corresponding groove in the rod of the saddle
support. Or I may provide similar grooving in the upper and lower rings instead
or in all three rings.
The invention is applicable to many other holding appliances such for instance
as holders for test tubes, sliding rods for ventilators, surgical appliances, telescope
toasting forks, and stands and hangers for displaying articles for sale in shop
windows, counters and other places.
