Abstract
Abstract A machine for collating sheets of paper. A photoelectric-sensing device determines whether more than one type of a sheet has been fed, while a spring contact sliding against a roller determines the absence of a sheet. If either more than one sheet is sensed or the absence of a sheet is detected, an electrical path is closed by a cam operated by movement of the conveyor of the machine. This closing shuts down the conveyor and a machine operator can then correct the sensed problem.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
232 words
A machine for collating sheets of paper from a plurality of stations to form sets comprising, in combination: a plurality of inclined tables for supporting stacks of identical sheets, provided close to a conveyor which transports sets of collated sheets, each of the tables being provided with a feeding roller means adapted to withdraw the uppermost sheet of the stack and to drop it down onto the conveyor, at least some of the tables having a first sensing means for detecting feeding of more than a single sheet and formed as a photoelectric device, and a second sensing means for detecting failure to feed a sheet and formed as a contact roller and an associated sliding contact bearing against the contact roller and adapted to be disengaged therefrom by a delivered sheet passing between the contact roller and the sliding contact; and at least one conveyor-operated switch means for opening and closing a line, and coupling means for coupling said conveyoroperated switch means to said conveyor for intermittently operating said conveyor-operated switch means upon movement of the conveyor; further switch means operated by the first and second sensing means being effective to establish a connection upon no sheet or more than a single sheet being delivered by a said feeding roller means, and means for utilizing said connection for effecting stoppages of the conveyor upon subsequent operation of said conveyor-operated switch means.
Claim 2
Dependent Claim

A machine for collating sheets of paper from a plurality of stations to form sets comprising, in combination: a plurality of inclined tables for supporting stacks of identical sheets, provided close to a conveyor which transports sets of collated sheets, each of the tables being provided with a feeding roller means adapted to withdraw the uppermost sheet of the stack and to drop it down onto the conveyor, at least some of the tables having a first sensing means for detecting feeding of more than a single sheet and formed as a photoelectric device, and a second sensing means for detecting failure to feed a sheet and formed as a contact roller and an associated sliding contact bearing against the contact roller and adapted to be disengaged therefrom by a delivered sheet passing between the contact roller and the sliding contact; and at least one conveyor-operated switch means for opening and closing a line, and coupling means for coupling said conveyoroperated switch means to said conveyor for intermittently operating said conveyor-operated switch means upon movement of the conveyor; further switch means operated by the first and second sensing means being effective to establish a connection upon no sheet or more than a single sheet being delivered by a said feeding roller means, and means for utilizing said connection for effecting stoppages of the conveyor upon subsequent operation of said conveyor-operated switch means.
Claim 3
Dependent Claim
120 words
A machine according to claim 1, further comprising a second conveyor-operated switch means for turning said feeding roller means on and coupling means for coupling said second conveyor-operated switch means to said conveyor for intermittently operating said second conveyor-operated switch means upon movement of the conveyor, both coupling means including rotatable cam discs, the cams of the cam discs being angularly displaced relatively to each other, so that the second conveyor-operated switch means operates a determined period in the cycle of the machine before the first-recited conveyor-operated switch means whereby the conveyor continues to move for an interval after the feeding roller means is on, even though the second sensing means has sensed that a sheet has not been fed.
Claim 4
Dependent Claim
64 words
A machine according to claim 2, the feeding roller means of each table including a feeding roller, a drive shaft carrying the feeding roller, and an electromagnetic coupling means for coupling the drive shaft to a source of mechanical power, which electromagnetic coupling means is controlled by an electrical circuit including said sensing means and the conveyor-operated switch means controlled by the cam discs.
Claim 5
Dependent Claim
75 words
A machine according to claim 3, in which the contact roller, against which the sliding contact bears, is coupled to a relay having a normally open switch which lies in a holding circuit of a further relay adapted to be operated by said second conveyor-operated switch means, a contact of the further relay being electrically connected to the electromagnetic coupling means and another contact of the further relay being connected with the first sensing device.
Claim 6
Dependent Claim
55 words
A machine according to claim 1, said feeding roller means including a separator roller resiliently abutting the uppermost sheet of each stack, a feed roller, and a friction wheel, the separator roller being driven by its feed roller by means of frictional contact of the friction wheel with the separator roller and the feed roller.
Claim 7
Dependent Claim
33 words
A machine according to claim 1, further comprising forwarding rollers positioned adjacent the feeding roller means, the sheet fed by the feeding roller means passing through the forwarding rollers and onto the conveyor.
Claim 8
Dependent Claim
41 words
A machine according to claim 4, in which the relay, the further relay, the electromagnetic coupling means, and a relay in said means for utilizing are connected to an electrical supply source and through at least one more switch to ground.
Claim 9
Dependent Claim
51 words
A machine according to claim 7, in which the relay in said means for utilizing and the first-recited conveyor-operated switch means are provided in an end station, A groundable control line and a power supply line being common to all stations, the groundable control line including the first-recited conveyor-operated switch means.
Claim 10
Dependent Claim
28 words
A machine according to claim 8, in which the groundable control line and the power supply line which are common to all stations are interconnected by plug-and-socket connections.
Claim 11
Dependent Claim
31 words
A machine according to claim 1, in which the stations are provided with hand-operated switches by which the feeding roller means and the conveyor respectively may be switched on or off.
Claim 12
Dependent Claim
51 words
A machine according to claim 1, in which the first or the last station is provided with a counting relay means, operated by electric pulses generated in dependence on the sheets which are delivered, for causing the feeding of interleaving sheets after delivery of all the sheets belonging to a set.
