Abstract
Abstract A device for controlling the standstill period of intermittently moving elements as a function of the speed of continuously moving mechanical members. These members operate a first disc of a clutch slipping on a second disc, which is normally kept stationary by a latch and carrying in turn a ratchet which, when said latch is released, concurrently with the stop of said elements, and the second disc rotates along with the first disc, acts upon a switch controlling the movement resumption for said moving elements.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
209 words
A device for controlling the standstill period of intermittently moving elements as a function of the continuous movement of mechanical members, comprising a first rotating body firmly rotably driven with said continuously moving mechanical members, a second body freely rotable about an axis coincident with the axis of rotation of said first body, frictional seals interposed between said first and second bodies and fast with one of said bodies, yielding eleMents urging one of said two bodies against the other, at least one detent fast with said second body, at least one locking member acting under inoperative or rest conditions on said detent to prevent said second body from rotating, a device for moving said locking member relative to the detent, at least one limit switch acted upon by the intermittently moving elements at each end of stroke thereof, generating a pulse operating the control device of said locking member by causing it to temporarily move away from said detent and causing said intermittently moving elements to stop, at least one ratchet carried by said second body, and at least one rod operable by said ratchet and connected to members controlling, under the conditions said rod is operated by the ratchet, the movement resumption for said intermittently moving elements.
Claim 2
Independent Claim
209 words
A device for controlling the standstill period of intermittently moving elements as a function of the continuous movement of mechanical members, comprising a first rotating body firmly rotably driven with said continuously moving mechanical members, a second body freely rotable about an axis coincident with the axis of rotation of said first body, frictional seals interposed between said first and second bodies and fast with one of said bodies, yielding eleMents urging one of said two bodies against the other, at least one detent fast with said second body, at least one locking member acting under inoperative or rest conditions on said detent to prevent said second body from rotating, a device for moving said locking member relative to the detent, at least one limit switch acted upon by the intermittently moving elements at each end of stroke thereof, generating a pulse operating the control device of said locking member by causing it to temporarily move away from said detent and causing said intermittently moving elements to stop, at least one ratchet carried by said second body, and at least one rod operable by said ratchet and connected to members controlling, under the conditions said rod is operated by the ratchet, the movement resumption for said intermittently moving elements.
Claim 3
Dependent Claim
38 words
A device as claimed in claim 1, wherein said yielding elements urging said first and second bodies to each other comprise a spring, one end of which is acted upon by a nut mounted on a threaded shaft.
Claim 4
Dependent Claim
30 words
A device as claimed in claim 2, wherein the continuous movement of said mechanical members is a rotary motion and the intermittent movement of said elements is a reciprocation motion.
Claim 5
Dependent Claim
43 words
A device as claimed in claim 3, wherein said intermittently moving elements are driven by a mechanical drive, in which a clutch is connected as operated by a control member, and the disengagement of which causes said elements to come to a stop.
