I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN MECHANICAL MOVEMENTS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
This invention relates to a mechanical movement applicable to presses and other
machinery where a dwell is required for feeding and other purposes.
In the accompanying drawing
Figure 1 is an end elevation of a mechanical movement embodying this
invention.
Figure 2 is a top or plan view thereof.
Figure 3 is a vertical section on the line x, x, Figure 2.
Figure 4 is a vertical section on the line y y, Figure 2.
Similar letters of reference indicate corresponding parts in the several figures.
A is a housing or frame on which is mounted the driving shaft B, the latter
having attached to it a pulley C and a pinion D. Meshing with the pinion D is a
mutilated pinion E, which is secured to a shaft F, the latter being also mounted on
the housing or frame A.
To one side of the pinion D is fixed a cam G, which is so disposed that when
required it may act on an arm or finger H, which is movably connected with the
pinion E. Encircling the shaft F is a clutch or sleeve J, to which said finger H is
attached; and projecting from the side of the pinion E are lugs K, forming guides
between which the finger H is fitted and plays, the finger thus being adapted to
rotate with said pinion E.
L represents a shipper or lever which is employed for moving the finger H in
opposite directions for the purpose of throwing it in and out of gear with the
cam G.
Secured to the pinion D on the side opposite to the cam G is a wiper M, so
located that it acts upon a spring arm or bar N which is connected with the housing
or frame A, and provided with a recess or opening a to receive a pin or stud P
projecting from the side of the mutilated pinion E opposite to the finger H.

page_text: Power is applied to the shaft B, whereby the pinion D is rotated and the lever G
is properly shifted so as to force the finger H towards the pinion E it being noticed
that the cam G is in advance of said finger H. The pinion E receives rotation from
the pinion D until the teeth of the latter reach the mutilated or untoothed portion
of the former, when said pinion E, and consequently the shaft F, becomes stationary,
and thus a dwell is imparted to the machinery with which the shaft F is connected
or in communication, thus allowing time for feeding and other purposes.
"
During the dwell," the spring arm engages with the stud P, thus tightly
holding the pinion E. The pinion D continues its rotation making the second
turn, and as the finger H is now in the path of rotation of the cam G, it is struck
by the latter. Simultaneously therewith or just in advance of the same, the
wiper M enters between the arm N and the wheel E, and forces said arm from the
stud P, and thus as the finger is pressed by the cam G, the pinion E is rotated and
the teeth of the pinion D again mesh with those of the pinion E, the latter thus
being fully rotated until the teeth of the pinion D reach the mutilated portion of
the pinion E, when another dwell is occasioned as hereinbefore stated.
The lever or shipper L may be connected with other parts of a machine in order
to be automatically operated, or the finger H may be a fixture of the pinion E, so
that the said pinion may be automatically stopped and started as long as tho
machine is running.
The pinions may be changed in their relative sizes, in order to be adapted for the
machines to which they are applied, observing the rule that when the mutilated or
driven pinion is to revolve revolution for revolution with the other pinion or driver,
and stop one revolution, it should be as much larger as will leave as many teeth as
the driver after it has been cut away to clear, said rule being applicable in any
multiple or division of relative sizes.
The mechanical movement may be applied to printing, punching, shearing or
stamping presses, and other machines where a given time is required for feeding or
other purposes, and by the use thereof the reciprocating or other movements of a
machine may be shortened, thus giving more leverage or power.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign Correspondents, I declare that what I claim is
First. A pinion and a mutilated pinion, provided respectively with a cam and a
finger, substantially as, and for the purpose, set forth.
Second. Pinions, substantially as described, in combination with a stud on one
of the pinions, a wiper on the other pinion, and a spring arm, said arm engaging
with said stud, and being released by the action of said wiper, for the purpose set
forth.
Third. Pinions, substantially as described, in combination with a clutch, guides
secured to one of the pinions, a finger connected with said clutch, and a cam on the
other pinion, said finger being movable in the guides and rotatable there with as
stated.
