Total Claims: 11
Claim 1
Independent Claim
213 words
A machine for feeding pieces of linen onto a conveyor, comprising rails adjacent the conveyor, a movable carriage supported for linear movement on said rails, a clamping device carried by the carriage to clamp the fore-edge of a piece of linen and to draw said fore-edge to a position above said conveyor in a forward position of the carriage, said carriage having a retracted position on said rails in which said clamping device is positioned to receive a said fore-edge of a piece of linen, a driving drum disposed beneath said carriage in said retracted position For advancing linen in the direction of the conveyor, means for intermittently driving said driving drum, a pressing drum also located beneath the movable carriage in said retracted position and displaceable toward and away from said driving drum selectively to press a said piece of linen against said driving drum, and means to move the pressing drum toward the driving drum to press a said piece of linen against the driving drum and to deenergize said drive means for said driving drum after said fore-edge is in said clamping device so that the pressing drum and the driving drum rotate freely as the piece of linen is being conveyed forwardly by the advance of the clamping device.
Claim 2
Dependent Claim
213 words
A machine for feeding pieces of linen onto a conveyor, comprising rails adjacent the conveyor, a movable carriage supported for linear movement on said rails, a clamping device carried by the carriage to clamp the fore-edge of a piece of linen and to draw said fore-edge to a position above said conveyor in a forward position of the carriage, said carriage having a retracted position on said rails in which said clamping device is positioned to receive a said fore-edge of a piece of linen, a driving drum disposed beneath said carriage in said retracted position For advancing linen in the direction of the conveyor, means for intermittently driving said driving drum, a pressing drum also located beneath the movable carriage in said retracted position and displaceable toward and away from said driving drum selectively to press a said piece of linen against said driving drum, and means to move the pressing drum toward the driving drum to press a said piece of linen against the driving drum and to deenergize said drive means for said driving drum after said fore-edge is in said clamping device so that the pressing drum and the driving drum rotate freely as the piece of linen is being conveyed forwardly by the advance of the clamping device.
Claim 3
Dependent Claim
49 words
Feeding machine according to claim 1, comprising an actuating device presenting a double effect jack connected to the movable carriage to provoke its linear displacements, a jack provoking the opening and the closure of the clamping device and a double effect jack controlling the displacements of the pressing drum.
Claim 4
Dependent Claim
62 words
Feeding machine according to claim 1 in which the pressing drum is pivoted between two angularly displaceable arms and these two arms are connected by a plate along a portion of their length to receive the rear part of a piece of linen when its fore-edge is clamped in the clamping device and before a cycle of the feeding machine is started.
Claim 5
Dependent Claim
61 words
Feeding machine according to claim 1, in which the last-named means comprises a further a photoelectric cell detecting the presence of a piece of linen and controlling the through the intermediary of a control circuit the different movements of the movable carriage, of the pressing drum, the opening of the clamping device as well as the driving of the driving drum.
Claim 6
Dependent Claim
52 words
Feeding machine according to claim 1, in which the clamping device is constituted by a corner iron having unequal wings hinged along the edge of the greatest wing and the edge of the little wing of which is adapted to enter into contact with a counterpiece of a supple and resilient material.
Claim 7
Dependent Claim
30 words
Feeding machine according to claim 1, in which the clamping device comprises an upper part provided with a supple and resilient coating adapted to enter into contact with a counterpiece.
Claim 8
Dependent Claim
33 words
Feeding machine according to claim 6, characterized by the fact that the upper part of the clamping device is constituted by two halves extending each over half the width of the feeding machine.
Claim 9
Dependent Claim
42 words
Feeding machine according to claim 7, characterized by the fact that the actuating device comprises further a double acting jack controlling the linear displacements, in opposite direction, of the two halves in a direction parallel to the axis of the driving drum.
Claim 10
Dependent Claim
90 words
Feeding machine according to claim 1, in which the clamping device comprises further a brush mounted on the movable carriage and displaceable angularly between a service position in which it rests on the base of the movable carriage in front and parallelly to the clamping device and a raised rest position and in which the angular displacements of the brush are controlled during the linear displacement of the carriage by the cooperation of a roller carried by the brush with a cam carried by the frame of the feeding machine.
Claim 11
Dependent Claim
52 words
Feeding machine according to claim 1, in which the control circuit comprises at least one manual contactor for the closing of the clamping device and a locking hindering any displacement of the movable carriage out of its rest position as long as the pressing drum is not in its retracted rest position.
