I WALTER WARD of West End Dye Works, Halifax in the county of York, Dyer
do hereby declare the nature of this Invention to be as follows :-
My improvement consists of a lamp containing only one fixed wheel, which acts as
a brake wheel (by means of a brake rod and spring) upon the carbon feed, and so
simplifies the lamp.
For striking the arc 1 employ a small pivotted lever (above the coils) on which is a
pulley for the cord from the carbon feed rod to pass under; a bracket, and regulating
screw is fixed to regulate the movement of the lever, when the current pulls down the
lever in contact with the coil, it draws the carbon apart and thus establishes the arc.
Dated this Thirteenth day of October 1886.

page_text: I WALTER WARD of West End Dye Works, Halifax, in the county of York, Dyer,
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:
My improvements consist of a lamp containing only one wheel, which acts as a
brake wheel (by means of a brake rod and spring) upon the carbon feed, and so
simplifies the lamp; this wheel revolves on fixed bearings or centres, and may be
either plain or milled upon its periphery. The shunt coils draw down the lever and
take off the brake, and so feed the lamp.
The cord is attached to the top of the carbon feed rod, and passes over the top
pulley, several times around the boss of a ratchet wheel, (which is loose upon the
shaft of the brake or fixed wheel) and again to the top carbon feed rod or holder.
The ratchet and ratchet wheel prevent the brake wheel from revolving backward when
pushing up
the carbon holder to renew the carbon.
For striking the arc, I employ a vertical rod on which is a keeper over the main
coil, the rod is connected to a sliding bottom carbon holder, when the keeper is
brought in contact with the coil, it pushes down the bottom carbon holder, and strikes
the arc; suitable springs return the sliding carbon holder to its original position
when the current is cut off.
Fig. 1 is a front elevation of my improved electric lamp.
Fig. 2 is a side elevation in section of Fig. 1, on the line A. B.
Fig. 3 is a front elevation showing cord attachment of carbon holder.
Fig. 4 is a modification of my improved lamp.
C is the wheel revolving in fixed bearings or centres, which with the brake rod or
lever D, acts as a brake wheel upon the carbon feed, E is the spring, F is the cord
which is attached to the top of the carbon feed rod G, passes over the top pulley H,
several times around the boss of the catch or ratchet wheel J, and is again attached
to the carbon feed rod G, K is the bottom sliding carbon holder, to which is attached
the vertical sliding rod L, on which is the keeper M, over the main coil N; when the
keeper M is brought in contact with the main coil N, it pushes down the bottom
carbon holder K, and strikes the arc, the spring P returns the sliding carbon holder
to its original position when the current is cut off, R are shunt coils for feeding
the lamp.
For a cut out I employ an extra coil S with armature T upon a pivotted lever U,
the lever U has an arm V and spiral springs V1 and V³, so that if the carbons get

page_text: too far apart, the coil S draws down the lever U and brings the arm V in contact
with the blade spring W and by means of the connecting wire X cuts out the
current from the lamp, the spring V₁ being over the centre of the pivot of the lever
keeps it down when in contact, this arrangement will act either automatically or by
hand as a switch.
My modified lamp as shown at Fig. 4 has but one coil N¹, which is wound to act
both as shunt and main coil, the brake lever D is placed above the wheel C, the
cord F is attached to the bottom carbon holder which slides on guide rods, and passes
round the boss of the ratchet wheel J, and terminates with a weight; to strike the
arc, the top carbon rod G is drawn up by the keeper M in connection with the coil N¹.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
1. In electric lamps, the use of one revolving wheel in fixed centres with lever
acting as a brake upon the carbon feed, substantially in the manner hereinbefore
shown and described.
2. Regulating the carbon feed by means of the cord passing around the boss of the
ratchet wheel, substantially as shown and described.
3. For striking the arc, the use of the sliding rod and keeper, operating the bottom
sliding carbon holder, substantially as shown and described.
