Improvements relating to Engaging Devices for Olutches and other
Mechanism.
I, JAMES WILLIAM PAIGE, of No. 102 The Vincennes, corner of 36th Street
and Vincennes Avenue, Chicago, in the County of Cook and State of Illinois,
United States of America, Inventor, 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 statemont :-
My invention has reference and is applicable to all kinds of machines in which
any one or more working parts, normally at rest, are desired to be brought into
action at irregular intervals in harmony, with the regular moving parts of the
machine or with the primary driving mechanism thereof in such manner as to
avoid conflict with or injury to the connecting or coacting parts...
To these ends, my invention consists of an attachment in the form of tas
reciprocating slide in operative connection with the primary driving mechanism,
80 as to reciprocate continuously in synchronistic harmony therewith and provided
with a roller which is interposed between it and a surface, preferably flat, the
whole of which is adapted to normally occupy a given position with reference to.
the roller, but a part of which surface may be arbitrarily moved out of its normal
plane at any time at the will of the operator. Means, such as a spring, is
provided for pressing the roller against said surface, which, being unvaried
when in its normal position, permits the flat surface of the roller to slide thereon:
until a change in the surface occurs, when the roller upon reaching, in its regular
reciprocating movement, the varied part of the surface, is caused by such
variation, to rotate upon its axis:-thus moving the slide out of its normal plane
and into operative contact with the releasing mechanism adapted to release the
clutch or other device provided for controlling the mechanism desired to be
brought into action. The variation of the surface. which causes the roller to be
actuated, is under the arbitrary control of the operator and may be restored to its
normal condition at will; all of which is hereinafter more particularly described.
For the purpose of describing my invention I have shown it as applied to an
ordinary punching machine in which the tool is normally at rest while the driving
pulley is driven continuously.
In the accompanying drawings
Figure 1 represents a side view of a punching machine having my improved
synchronizing device applied thereto,
Figure 2 is an enlarged detail side view of a portion of said machine in which
the driving pulley is shown in section and a portion of the casing is broken away
to show the synchronizing attachment,
Figure 3 is a sectional view in detail taken upon the line 3-, Figure 2, as viewed
in the direction of the arrow there shown, and

Figure 4 is a detail view taken upon the same line but viewed in an opposite
direction from that of Figure 3.
.I will now proceed to give
operation of my improved device.
a detailed description of the construction and
Referring to the drawings, a represents the frame of an ordinary punching
machine having the jaws bc, between which the work is placed in order to be
operated upon by the usual working tool which is connected by means of a
pitman, Figure 1, to an eccentric e, which is rigidly attached to a driving
DJ7

page_text: shaft f. The latter, which is mounted in suitable bearings in the frame, has
loosely secured thereon so as to rotate independently thereof, a driving pulley g,
which is connected by means of a belt to a source of power and is intended to be
driven continuously. Keyed rigidly to the shaft f, is a collar i, Figures 1, 2
and 4, upon the inner face of which is formed a recess j, Figure 4, which is
adjacent to the hub h of the driving pulley. The hub is also provided with a
recess k, Figure 2, into which is loosely fitted a clutch bolt which is adapted to
engage with the notch or recess j'into which, when released, it is thrust by means
of a spiral spring m, Figure 2, placed within the recess, thus clutching the
driving pulley to the shaft and thereby actuating the clutching mechanism.
It is obvious that unless some means is provided to cause the clutch-bolt to be
thrust out at the proper instant of time with reference to the rotation of the
pulley and the relative position of the notch, there would be danger of either
failing to connect or of breaking or injuring the machine. It is to insure the
action of the clutch-bolt, positively or otherwise, at the proper instant of time and
in harmony with the driving mechanism, that my improved synchronizing
attachment is provided. The clutch-block is preferably provided with a notch in
its under face with which a detent n upon the arm o pivoted within a recess in the
hub as shown in Figure 2, is adapted to engage when the bolt is in its, normal
unclutched position. The arm ois preferably bent as shown and is provided with
an extension p, upon its outer end for the purpose hereinafter stated. Interposed
between the driving pulley and the frame and rigidly attached to the latter is a
in which is secured in vertical guides a bar r, connected by means of a
rod, to a treadle, which is not shown, but may be of any well known pattern.
A spiral spring interposed between the casing and a stop upon the bar r serves
to raise the latter and to hold it in a normal position. A horizontal armis
rigidly attached to the frame a and is provided with a bevelled working face as
shown in Figure 4 in operative proximity to the bolt, so that with each
revolution of the pulley g, the clutch-bolt is, if protruding, pushed back within
its recess and there retained by the detent n which is caused to engage the notch
in the bolt by means of a spiral spring o' acting upon the arm o. Fitted loosely
within the recess in the case q is a square block s which is connected with the
barr by means of an elbow lever pivoted within the casing. When the bar ris
in its normal position, the face of the block sis even with the face of the
casing, thus forming upon the latter an even smooth surface.
case,
:
Within a guide bearing on the casing q is also fitted a slide which is connected
as shown in Figures 2 and 3 by means of a pitman t to an eccentric upon the
hub h which causes the slide't to be reciprocated with each revolution of the
driving pulley. Pivotally attached at to the slide t, is an arm u which is
provided with a roller v preferably circular in form with the exception that it is
provided with a flat or cut away portion v. A spring u attached to the slide,
presses the roller v against the flat surface of which the block as stated, when
in its normal position, forms a part. A hook u³ upon the end of the arm u is in
position to engage the part p of the arm o when the roller is not resting upon the
Hat face v; but when so resting, the arm u may be reciprocated by the slide t
without bringing the hook into contact with the releasing arm. Assuming the
block s to be in its normal position, thus presenting a continuous flat surface to
the roller, the movement of the slide t causes the latter to roll
пров its, axis
until its flat surface is in contact with the flat surface, after which the roller
ceases. to rotate but merely slides upon its flat face. This action may be
continued as long as the block & remains in its normal position; but in case the
treadle is depressed and the bar thereby drawn down, the. blocks is withdrawn,
thus forming a recess into which the roller is pushed by the spring u³ as the
slide is reciprocated. This causes the roller. to rotate, thus moving its axis
further away from the fat surface and bringing the hook u³ into the path of
movement of the part p. The further movement of the slide t causes the detent.n
to be withdrawn which releases the clutch-bolt. As this action can only occur at

a time in the revolution of the driving wheel when it is safe to throw the clutch-
block, it renders the clutching action certain and free from danger of injury to the
engaging parts. Upon releasing the treadle, the bar is lifted to its normal.
position by the action of the spring, thus restoring the blooks to its normal
position, and upon the succeeding, revolution of the driving pulley, the clutch-
bolt is brought into contact with the bevelled face of the part, thus forcing
the bolt into the recess k where it is held by the detent n until the treadle is
again actuated and the hook u is again brought into contact with the releasing
arm as a result of the action of the roller v. It will be observed that the clutch-,
bolt, if released, will be sheared back with each revolution of the driving,
pulley.
'
I have termed the part va "roller" because it does, under abnormal conditions,.
rotate or partially rotate upon its axis; but as the sole object is to produce a
partial rotation upon the withdrawal of the blocks so as to increase the distance
of the axis from the surface and thus bring the part u³ into engagement with
the part p it is obvious that the part,u may be of any suitable form, such, for
example, as rectangular or polygonal, provided there is an angle thereon to.
engage with the shoulder of the recess formed by the withdrawal of the block & so
as to cause the partial rotation described. 1 will, therefore, in the claims,
designate the part vasia roller, with the understanding that it may be of any shape
capable of sliding or rotating according to the relative position of the blocks with
respect to the surface r.
Instead of employing the spring m to throw out the clutch-bolt when released
by the action of the arm o, it is manifest that one arm of an elbow lever may be
connected directly with said bolt, and the other arm placed in operative
proximity to the part when moved into an abnormal position. This would
enable the bolt to be actuated positively by the part at the proper time, after
which it could be sheared back into position by the positive means hereinbefore
described.
The hook may be dispensed with and the part.u made to actuate or release
the intermittently movable mechanism by contact with its end when moving in an
opposite direction from that indicated.
It is obvious that my improved synchronizing device may be applied to any
machine or mechanism in which it is desired to cause
use supplemental parts or
mechanisms to be brought into action in harmony with the regular movement of
any given part or with that of the primary motive power. The connections and
adjustment of the parts may be modified indefinitely without departing from the
principle of my invention, so long as the features of the continuously movable
part u in operative connection with the regular moving part of the machine, the
arbitrarily variable surface and the flat faced roller vare employed.
For example the part may be mounted upon a shaft and caused to rotate or
oscillate thereon while the roller is held with resilient pressure against a circular
or curved surface of which the blocks may form a part. The removal of the
block may change the regular continuity of the surface and thereby actuate the
roller and change the path of movement of the arm upon which the roller is placed
thus causing the intermittently movable mechanism to be brought into action.
My invention is especially applicable in connection with type setting and type
justifying machines in which it is necessary to so control the action resulting from
the arbitrary and irregular movement of key mechanism as to render it subservient
to and synchronous with the primary moving power.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. An automatic synchronizing attachment for harmonizing the co-action of
simultaneously and intermittently acting mechanisms, consisting of a continuously
moving device in operative connection with the regular moving mechanism and

page_text: also in operative proximity to the intermittently movable mechanism, a roller
having a flat surface upon its periphery, said roller being operatively connected
with said continuously moving device, a normally uniform surface forming the
tread of said roller, and means for arbitrarily varying the 'continuity of said surface
to cause the rotation of said roller and the resultant abnormal movement of said 5
continuously moving device and the consequent actuation of said intermittently
acting mechanism; substantially as described.
2. In an automatic synchronizing attachment for harmonizing 'the co-action' of
regular and intermittently acting mechanisms, the combination of' a continuously,
moving device in operative connection with a continuously moving part,' said
device being adapted to be brought into engagement with said intermittently!
moving mechanism, a roller upon said device, said roller having one or more flat
faces, means for pressing said roller against an adjacent and normally uniform
surface with a yielding pressure, a movable block adapted when in its normall
position to form a part of said surface constituting the tread of said roller, and'
means for actuating said block at the will of the operator so as to form a notch or
recess in said surface, substantially as described.
