Improvements in Electro Metallic Depositing Apparatus.
Year: 1897

page_text: We, Jon EBORALL HARTLEY and HERBERT EDWARD HARTLEY, both of 13,
Saint Paul's Square, in the City of Birmingham, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in electro depositing apparatus and its
primary object is to provide a simple, cheap, and handy contrivance, which may
be easily used; principally where but small quantities are required to be plated
at the same operation. Also this improved contrivance, may be readily and in-
expensively applied to existing plants where there is no mechanical movement
imparted to the work.
A basket or cage is suspended vertically in such a manner that it has imparted
thereto a horizontally rotative motion. For small light work this may be effected
by a meat roasting jack or other similar contrivance, or by banding or gearing
from other suitable motive force.
Below the cage and preferably suspended therefrom and lying parallel thereto
is the anode or anodes, or, such may be similarly carried around the sides of
the basket.
More than one of such baskets &c. may be used simultaneously in the same
bath or more than one may be arranged, the one above the other from the same
suspension.
In some cases we may modify the means of carrying the work (cathodes) as
that a ring may be suspended having depending hooks or their like therefrom.
Also in such cases we may suspend a central anode. Also we may provide means
whereby (in the case of mechanical movement) an intermittent or occasional
tilting or jerking of the basket, ring or other cathode carrier may be effected.

Improvements in Electro Metallic Depositing Apparatus.
We, JOHN EBORALL HARTLEY. and HERBERT EDWARD HARTLEY, both of 13,
Saint Paul's Square, in the City of Birmingham, Manufacturers, do hereby
declare the nature of this invention and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement: —
This invention relates to improvements in electro depositing apparatus and its
primary object is to provide a simple, cheap, and handy contrivance, which may
be easily used principally where but small quantities of work are required to be
plated at the same operation. Also this improved contrivance may be readily and in-
expensively applied to existing plants where no mechanical movement is at present
imparted to the work.
In crder to more clearly explain this our invention, we have appended hereunto
illustrative drawings upon which are figures and numbers of reference.
Fig. 1, is a general view of this our invention, showing the anode carried hori-
zontally with the cathodes.
Fig. 2, shows a modification of this our invention, in which the anode is sus-
pended vertically, and further showing a modification in the carrying of the
articles to be plated.
Referring to Fig. 1, is the cathode carrier which is freely hung upon the
central revoluble rod 5, by means of chains or cords 6, and to which is given a
ratative movement about a vertical axis, by means of the revoluble rod 5, with
pulley 7, or other suitable driving means. Preferably the carrier 4, is made to
be raised out of and lowered into the bath by any ordinary device, but such rais-
ing and lowering mechanism not forming part of this our invention, we have not
illustrated any means of doing so. The rim or body of the carrier is made of
wood or other suitable non-conductive material, while the net work 9. constitut-
ing the bottom is usually made of copper, but in some cases may be made of
brass. 10, is the anode which is supported from the wooden carrier 4, by means
of the supports 11, which may be of any suitable material, so long as they form
no electrical circuit. In some cases if desired a further anode may be carried
above the carrier as indicated in dotted lines at 10. This anode 10%, may be
readily carried upon or from the cords 6, or by means of a light wooden frame
carried upon the chains 6, upon or across which the anode 10" (preferably) in
strips may be laid across, care of course being taken that they are insulated from
the cathodes. By one or both of these anodes it will be seen that a very equal
action is given off to the whole surface of the carrier.
Upon the carrier 4, we provide a camlike surface 12, and a roller 13. which
latter is fixedly carried from the side of the bath, so that as the carrier revolves
it shall be subjected intermittently to a shaking or stirring movement for the
displacement of the articles being plated.
In order to convey the current of electricity to the anode we employ the loose
collar 14, which encircles the (nonconductive) sleeve 5, (which is detachably con-
nected up to the rod 5) by hook stem 5°. The collar 14, does not revolve with
the sleeve 5º. To this collar 14, is connected the current wire 15. This collar 14,
is placed in electrical contact with the collar 16, which revolves with the sleeve 5º.
and consequently with the carrier 4, and anode 10 &c.. so that the current passes
from the wire 15, through collar 14, to collar 16, thence by wire 17 to anode 10.
It will be readily seen that when an upper anode 10, is used a separate wire may
be carried therefrom to the collar 16, or it may be connected up to the wire 17
as at 17. The current is conveyed to the cathodes by means of the wire 18, and
nonrevoluble collar 19, through the rod 5, and central hook rod 5º, and wire 20,
which electrically connects the rod 5. with the net work 9, of the carrier which
latter of course forms the connection to the articles placed therein.
Referring to Fig. 2, it will be seen that we have shown how the carrier 4, may
he rotated by a motor of the roasting jack type, although we do not claim such
means. In this view we have however arranged the anode 10b to hang verti-
cally and centrally with the carrier. In this case the work to be plated may be
carried in or upon the carrier 4, in any desirable manner, such for instance as
upon the hooks 21. In this case the current is carried to the anode by the wire 15.

page_text: thence electrically through the motor means 22, rod 5°, and wire 17; while the
current to the cathodes passes from wire through nonrevoluble collar 14, through
revolving collar 16, wire 20, which latter is made to communicate with the cathode
hooks 21.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
1. In electro-plating apparatus, the rotative cathode carrier 4, suspended freely
by cords 6, with rotative anode carried therefrom and electrical connections, all
substantially as set forth and shown in Fig. 1.
2. A vertically freely suspended cathode carrier 4, having the cam surface 12,
with fixed controlling roller 13, as set forth and shown and for the purposes
specified.
3. In an electro-plating apparatus, the combination with a revoluble anode
and cathode, of the revoluble nonconducting sleeve 5", a cathode connection pass-
ing through such sleeve, the conducting collar 16, attached to such sleeve, and
electrically connected to the anode, the collar 14, loosely encircling said sleeve,
and resting upon the collar 16, and an anode connection to said collar 16, sub-
stantially as set forth and shown, in Fig. 1.
4. The combination with a freely suspended cathode carrier of the vertically
and centrally suspended rotative anode, arranged substantially as set forth and
shown in Fig. 2.
5. In an electro-plating apparatus the combination with a revoluble anode
and cathode of the revoluble nonconducting sleeve 5, an anode connection
passing through such sleeve, the conducting collar 16, attached to such sleeve,
and electrically connected to the cathode; the collar 14, loosely encircling said
sleeve and resting upon the collar 16, and a cathode connection to said collar,
substantially as set forth and shown in Fig. 2.
