PROVISIONAL SPECIFICATION.
Improvements in Means for Operating Hammers by Steam or other
Motive Power.
We, WILLIAM WHITTAKER and ISAAC PARKER both of Laneshaw Bridge,
near Colne in the County of Lancaster, Machine Makers, do hereby declare the
nature of this invention to be as follows, that is to say :-
It relates to improvements in means for operating hammers by steam or other
motive power and consists of constructing and arranging the parts forming these
said means so that the operations of said hammers may be effected in a more
desirable and efficient manner than heretofore.
The object of this invention is attained by mounting or attaching an extra arm
upon or to the oscillatory shaft upon or to which the arm or handle of the hammer
is mounted or attached, and upon this extra arm, which is made to extend in the
direction of the hammer's head, is mounted a stud carrying a conical bowl.
Mounted in bearings, that extend above the oscillatory shaft and hammer is
a rotary shaft (operated in any of the well known ways but preferably by being
coupled with gearing to another rotary shaft carrying a balance wheel and
receiving its motion from any prime motor) upon which is mounted an eccentric,
the same being arranged to operate a rod extending downwardly so that a hook,
formed in a suitable position near its extremity, may lay hold of the conical
bowl above described.
By suitably formed guide pieces, carried by the framework, this hook on the
rod is made to lay hold of said bowl, when said rod is in its lowest position, it
is also made by these guide pieces to maintain this hold while said rod is being
raised thus raising said bowl (and its arm as consequently also the hammer) and
until it is approaching its highest position at which part it is forced out of contact
therewith, so that the arm and the hammer are suddenly liberated and by gravity
descend so that the hammer may strike anything placed on the anvil beneath as
will be well understood. This rising and falling of the hammer being effected at
cach revolution of the eccentric.
To increase the effects of the hammer's blows that are given when the said
hammer descends by the action of gravity alone, instead of relying entirely upon
said gravity for causing its descent a spring or springs might be employed for forcing
it, when liberated, to fall.

COMPLETE SPECIFICATION.
Improvements in Means for Operating Hammers by Steam or other
Motive Power.
We, WILLIAM WHITTAKER and ISAAC PARKER both of Laneshaw Bridge
near Colne in the County of Lancaster, Machine Makers, 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, that is
to say :-
It relates to improvements in means for operating hammers by steam or other
motive power and consists of constructing and arranging the parts forming these

page_text: said means so that the operations of said hammers may be effected in a more
desirable and efficient manner than they have been heretofore.
In the accompanying sheets of drawings
Figs. 1 and 2 are side and front elevations of our improved means for operating
hammers.
Fig. 3 is side elevation of certain of 'the motor parts but the framework for
supporting same is omitted so that these parts may be more clearly seen.
Figs. 4, 5, 6 and 7 are drawings in detail illustrative of parts hereinafter
described.
Similar letters and figures refer to similar parts throughout the several views.
The object of this invention is attained by attaching or mounting (rigidly or
otherwise but preferably rigidly) the arm a' of the hammer a upon the oscillatory
shaft carried by the framework c upon this arm a¹ being mounted the bowl d by
means of its stud d'.
Upon the bearings formed on or attached to the framework c, is mounted a
rotary shaft e which is operated in any of the well known ways but preferably
by being coupled with the gearing wheels f, g and h so that it may be rotated
by the shaft k upon which are mounted the balance wheel and fast and loose
driving pulleys m m¹. Rotary motion is imparted to this shaft k through its
pulley m from any prime motor.
The shaft e has the eccentric n mounted upon it for the purpose of operating
the rod p vertically as well as laterally. This rod p has a hook p' formed at
or near its lower extremity for the purpose of laying hold of the bowl d.
By the guide bowl r (see Fig. 3) which is supported by the framework so as to
be rigidly held yet free to rotate, the hook p, on the rod p is made to lay hold of
the bowl d when the said rod p is in the position shewn in broken lines Fig. 3,
and said hook p' maintains this hold on the bowl d until, by the motion of the
eccentric n (in the direction indicated by the arrow 2) it, the said rod p, is moved
into the position approaching that shewn by full lines in said Fig. 3 in which
position it will have moved the hammer a into its highest or raised position shewu
by broken lines.
As the eccentric n continues to move, carrying the rod in a lateral as well as
vertical direction, the contact of the rod p with the guide bowl causes the hook p¹
to be moved clear of and from holding the bowl d on reaching their respective
positions shewn in full lines Fig. 3, and so the hammer a is free to fall by gravity
or said fall may be accelerated by the springs s. The rising and falling of the
hammer a is thus effected during each revolution of the eccentric n.
In order to arrest the hammer a in its raised position and hold it there during
the stoppage of the rotary motions of the eccentric n, a holding catch t is hinged
upon the stud u carried by the framework. On the same stud u is mounted the
lever and the hubs of this lever v and the catch t are so formed, by having
projections and recesses (see Fig. 7) that the lever v may operate the catch t in the
direction indicated by the arrow t' while in the other direction, when freed by the
lever v, the catch is operated by the spring w. The downward movement of
the lever v is effected by the spring a, which is of sufficient strength to overcome
that of the spring w, and the upward movement of said lever vis effected by the
incline y formed on or attached to the sliding rod y¹ which the belt guides for
moving the driving belt from the fast to the loose pulley m² when same are
operated by the handle lever z through the medium of the rod and forked
lever z².

When the handle is operated so as to move the rod y¹ to bring the belt from
the fast pulley m on to the loose pulley m', the incline y¹ is moved clear of the
lever and so the spring a pulls or draws same downwards causing the catch t to
move as described by which means it is in position for laying hold of the stud a² on
the arm a' when same is raised into contact with it, while when the handlez is
again moved to put the eccentric n into operation, the lever v is raised from pressing
the catch t and so its spring w may draw it clear of the stud a².

page_text: In the accompanying drawings the framework is shewn as carrying only one
hammer however it will readily be seen that two or more hammers and their
operating eccentrics may be mounted within or upon the same framework and
operated by one and the same. rotary shaft, but in this case but in this case the
retaining hooks, for suspending the hammers when not desired to be operated, will
have to be placed into and out of position by the operator and by a separate
handle instead of operating same automatically on operating the belt guide as above
described.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The arrangement and combination of means herein described whereby a
hammer is or may be operated by steam or other motor power substantially as
specified.
2. The method of operating a hooked rod by an eccentric and guide bowls so
that it will lay-hold-of, raise and liberate the arm of a hammer substantially as
specified and for the purposes set forth.
3. The combination of the hammer a, the hooked rod p, the eccentric n, the
hook t, lever v, sliding rod y and the incline y', all these parts being formed and
arranged to operate substantially as specified.
