IMPROVEMENTS IN ELECTRIC MANGERS FOR THE PREVENTION AND CURE OF CRIB BITING
Year: 1884

page_text: I BENJAMIN S¹ WESTON of 5 Parkholine Road Dalston in the County of Middlesex
and HENRY STAINES WILTON of 457 Oxford Street also in the County of
Middlesex do hereby declare the nature of our Invention for IMPROVEMENTS IN
ELECTRIC MANGERS FOR THE PREVENTION AND CURE OF CRIB BITING to be as
follows:-
To prevent the working parts of the electric manger cap being put out of order
.by water food & falling from the horses mouth we make the top or cap of the
manger in the form of an unequal ridge roof inclining towards the horse and pro-
jecting over the manger top front and back This roof is of metal and is divided
and insulated through the ridge with a strip of vulcanite, The roof is capable of
vibrating by means of hinges placed under the back end, upon springs placed
between it and the manger top, the horse bites the ridge of this roof which being
an obtuse angle necessitates a slight downward pressure to give him grip, this
downward pressure makes contact at the springs before mentioned with battery
and coil and a shock passes through the mouth of the horse, which has now closed
the secondary circuit between the insulated sides of the metal roof.

page_text: I BENJAMIN SAMUEL WESTON of 5 Parkholme Road Dalston in the County of
Middlesex Engineer, and HENRY STAINES WILTON of 457 Oxford Street also in
the County of Middlesex, Saddler, do hereby declare the nature of our invention
for IMPROVEMENTS IN ELECTRIC MANGERS FOR THE PREVENTION & CURE OF
CRIB BITING and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
To prevent the working parts of the Electric Manger Cap being put out of order by
water food & falling from the Horses mouth we make the top or cap of the Manger
in the form of an unequal ridge roof inclining towards the Horse and projecting
over the manger top front and back, this roof is of metal and is divided and
insulated through the ridge with a strip of vulcanite, the roof is capable of vibrating
by means of binges placed under the back eave, upon springs between it and the
Manger top, the Horse bites the ridge of this roof, which being an obtuse angle
necessitates a slight downward pressure to give him grip, this downward pressure
makes contact at the springs before mentioned, with Battery and Coil and a shock
passes through the mouth of the Horse which has closed the secondary circuit
between the insulated sides of the metal roof. To cure the habit of crib biting it
is necessary to remove all projections on the sides of the loose box, within the
Horses reach or otherwise to cover them with thin galvanized Iron, so that it is
impossible for him to crib anywhere except at the Manger, the cap of which we
construct with its edge at the most convenient angle to encourage the habit, the
angle of the cap A. Fig 1 is that best suited to the usual position of the Horses
mouth B when he sucks air.
Fig 2 is a transverse section of the Manger cap, A and A¹ being the front
and back Zinc plates forming the two sides of the roof insulated from each
other by the vulcanite strip C the under sides of the plates A are coated with
insulating composition and screwed upon the wood cap D by means of the screws B
and B¹ under the nuts of which the conducting wires are connected, the whole roof
cap is hinged to vibrate under the back eave at E upon the base board F which is
fixed to the Manger top G.
The Battery and Coil are detached from the Manger top but placed as near as
possible and out of reach of the Horse, we prefer to use 3 wires for the primary and
secondary current, Fig 3 shows the connections of the manger top, H and H¹ are
plunger springs enclosed in the base board F, these bear upon the adjustable
screws I and I¹ communicating with the cap plates and regulate the amount of
spring pressure sufficient to keep the contact J broken, these springs form the
permanent connection between the wires and the plates A and A¹ of the Manger
Cap. Fig 4 shows the disposition of the Battery, Coil and Manger Cap, one wire S
runs from the secondary coil C to the connecting spring H₁ another wire P & S
runs from the connecting spring H through both the primary and secondary screws
of the coil C the third wire P from the contact screw J which also communicates
with H, to the Battery B thence to the primary screw of the coil C. The secondary

page_text: wires therefore are always connected with plates A and A¹ and one primary also
with A¹ the other only when the slight downward pressure is exerted upon the
Manger Cap by the Horse in biting, when the secondary current passes between the
plates A and A¹ through the mouth of the Horse, 2 stops or buttons B placed near
the ends between the cap and base shown at Fig 5 limit the upward vibrating
movement of the Manger Cap, and allow it to be lifted open at pleasure exposing
the working parts for removing dust &c It will be seen that from the construction
of the cap it forms a solid close roof which prevents the droping moisture and food
in any way interfering with the electric action of the Manger Cap and the angle
formed by the cap ridge gives the Horse an inviting edge to crib upon, the Horse
must be kept in the one Stable until he is weaned from the habit of crib biting and
wind sucking.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim, is
The construction of a vibrating roof embodying the insulated conductors and
protecting the working parts and connections substantially as herein described.
