Abstract
Abstract A conveyor flight is connected to a roller link conveyor chain by a pair of spaced pins which project transversely from the chain. The pins are removably supported in transverse sleeves of the chain and have end portions which are removably received in spaced parallel bores in the end of the flight, with grooved portions which project into opposite sides of a transverse opening in the flight. A latch member on the flight has a portion projecting into the transverse opening, and said latch portion is dimensioned to releasably engage the exposed grooves in both pins to releasably latch the flight to the pins. The opposite sides of the latch portion are notched adjacent to the grooves in the pins, and the notched portions are positioned to be moved into alignment with the pins, when the latch member is manually depressed, to release the pins so that the flight can be quickly detached.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
153 words
In combination with a conveyor including at least one conveyor chain mounted for movement along a conveyor path, and including at least one conveyor flight extending transversely of said chain and connected thereto, the improvement wherein the means for connecting said flight to said chain includes a pin projecting laterally from said chain, a bore in said flight slideably receiving said pin, and cooperating latch means on said flight removably connecting said flight to said pin, said latch means including a groove on said pin and a manually operable latch element on said flight having a portion positioned for releasable engagement with said groove on said pin, said latch element including a manually operable yieldable portion which is normally positioned in releasable engagement with said groove, there being means in said yieldable portion adjacent to said groove which is movable to a position to permit said flight to be withdrawn from said pin.
Claim 2
Dependent Claim
153 words
In combination with a conveyor including at least one conveyor chain mounted for movement along a conveyor path, and including at least one conveyor flight extending transversely of said chain and connected thereto, the improvement wherein the means for connecting said flight to said chain includes a pin projecting laterally from said chain, a bore in said flight slideably receiving said pin, and cooperating latch means on said flight removably connecting said flight to said pin, said latch means including a groove on said pin and a manually operable latch element on said flight having a portion positioned for releasable engagement with said groove on said pin, said latch element including a manually operable yieldable portion which is normally positioned in releasable engagement with said groove, there being means in said yieldable portion adjacent to said groove which is movable to a position to permit said flight to be withdrawn from said pin.
Claim 3
Dependent Claim
45 words
The combination defined in claim 1 in which the means in the yieldable portion adjacent said groove is a recess, and in which said recess is movable to a position of alignment with said pin to permit said flight to be withdrawn from said pin.
Claim 4
Dependent Claim
59 words
The combination defined in claim 1 wherein there are two pins projecting laterally from said chain and two bores in said flight for receiving said pins, and wherein said latching means includes a groove in each of said pins and a manually operable latch element on said flight having means for releasable engagement with both of said grooves simultaneously.
Claim 5
Dependent Claim
61 words
The combination defined in claim 3 and further comprising an opening in said flight extending transversely of and intersecting said two bores to expose inner portions of said pins, said grooves being on the exposed portions of said pins, and said latch element being positioned within said opening and having opposing side edge portions which are releasably engaged with said grooves.
Claim 6
Dependent Claim
46 words
The combination defined in claim 4 wherein said opposing side edge portions of said latch element are recessed, with said recesses dimensioned and positioned to be movable into alignment with said pins to enable said pins to be easily withdrawn from said bores in said flight.
Claim 7
Dependent Claim
45 words
The combination defined in claim 5 wherein said latch member is L-shaped and made of yieldable material, with one portion projecting into said opening and another portion positioned on top of said flight and attached thereto beyond the margin of said opening in the flight.
Claim 8
Dependent Claim
41 words
The combination defined in claim 6 wherein the portion of said latch member which is on top of the flight is bent upwardly away from said flight to provide for yielding movement of the latch member in response to manual pressure.
Claim 9
Dependent Claim
90 words
In combination with a conveyor including at least one conveyor chain mounted for movement along a conveyor path, and including at least one conveyor flight extending transversely of said chain and connected thereto, the improvement wherein the means for connecting said flight to said chain includes two pins projecting laterally from said chain, two bores in said flight slideably receiving said pins, latching means on each pin, and a single manually operable latch element on said flight having means for releasable engagement with the latching means of both pins simultaneously.
Claim 10
Dependent Claim
90 words
In combination with a conveyor including at least one conveyor chain mounted for movement along a conveyor path, and including at least one conveyor flight extending transversely of said chain and connected thereto, the improvement wherein the means for connecting said flight to said chain includes two pins projecting laterally from said chain, two bores in said flight slideably receiving said pins, latching means on each pin, and a single manually operable latch element on said flight having means for releasable engagement with the latching means of both pins simultaneously.
Claim 11
Dependent Claim
111 words
In combination with a conveyor including at least one conveyor chain mounted for movement along a conveyor path, and including at least one conveyor flight extending transversely of said chain and connected thereto, the improvement wherein the means for connecting said flight to said chain includes a pin projecting laterally from said chain, a bore in said flight slideably receiving said pin as a result of pushing movement longitudinally only of said flight, and means including cooperating latch means on said flight and pin, one of which is yielding, removably connecting said flight to said pin when the latter has been fully inserted in said bore by said longitudinal pushing movement.
Claim 12
Dependent Claim
111 words
In combination with a conveyor including at least one conveyor chain mounted for movement along a conveyor path, and including at least one conveyor flight extending transversely of said chain and connected thereto, the improvement wherein the means for connecting said flight to said chain includes a pin projecting laterally from said chain, a bore in said flight slideably receiving said pin as a result of pushing movement longitudinally only of said flight, and means including cooperating latch means on said flight and pin, one of which is yielding, removably connecting said flight to said pin when the latter has been fully inserted in said bore by said longitudinal pushing movement.
