Abstract
Abstract A device for conveying fowl from one point to another includes a conveyor chamber through which air under pressure is forced, a fowl inlet to the chamber having a conduit section extending longitudinally downstream and terminating within the chamber and conduit means exiting from the chamber and having an upstream end positioned closely adjacent but longitudinally spaced apart from the termination of the conduit section of the fowl inlet. A flow separator disposed within the chamber upstream of the termination causes the air to accelerate in flowing thereabout and to thereby create an area of reduced static pressure at the termination of the conduit portion.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
222 words
A fowl conveying device comprising: a conveyor chamber having an upstream opening at one end and a downstream opening at the other end; air supply means communicating with said upstream opening for supplying air under pressure thereto; inlet means communicating with said chamber intermediate said openings for introducing fowl therethrough, said inlet means comprising a truncated conical inlet portion joined to an Lshaped conduit portion, the horizontal element of said L-shaped portion extending downstream and having a termination within said chamber; conduit means communicating with said discharge opening for receiving the fowl from said inlet means and conveying it to its destination, the upstream end of said conduit means positioned closely adjacent but longitudinally spaced apart from the termination of said element and coaxial therewith; flow separator means in said chamber upstream of said termination, whereby air under pressure entering said chamber is caused to diverge around said separator means and to converge downstream of said termination, said flow separator means comprising a fin circumferentially disposed about and extending into said chamber from at least the upstream facing portion of the periphery of said conduit portion, said fin forming a downstream opening acute angle with the longitudinal axis of said chamber; and baffles laterally disposed at a plurality of points within said conduit means to slow the rate of fowl movement therethrough.

Claim 3
Dependent Claim
25 words
A fowl conveying device, as claimed in claim 1, wherein said chamber and the horizontal element of said L-shaped portion are circular in cross section.
Claim 4
Dependent Claim
25 words
A fowl conveying device, as claimed in claim 1, wherein said element and the upstream end of said conduit means are coaxial with said chamber.
Claim 5
Dependent Claim
64 words
A fowl conveying device, as claimed in claim 1, wherein each of said beffles comprising a resilient disc having a central aperture therin and a plurality of slots extending radially from said aperture defining a plurality of flaps therebetween, whereby said flaps are adapted to deflect in a generally downstream arc out of contact with the fowl as the fowl pass through said baffle.
Claim 6
Dependent Claim
22 words
A fowl conveying device, as claimed in claim 1, wherein said element is concentric with said chamber about the longitudinal axis thereof.
Claim 7
Dependent Claim
25 words
A fowl conveying device, as claimed in claim 1, wherein said fin forms a downstream opening acute angle with the longitudinal axis of said chamber.
Claim 8
Dependent Claim
35 words
A fowl conveying device, as claimed in claim 6, wherein said fin extends circumferentially about and extends into said chamber from the sides and upstream facing portion of the periphery of said L-shaped conduit portion.
