Abstract

Abstract A corrugating machine includes a series of longitudinally axially elongated rods and two generally parallel chains, and means interconnecting the ends of the rods with chain links of the two chains so that the rod ends can swivel relative to the links to which they are connected, and including a universal joint between each rod end and associated link, the joint including a member having axially slidable telescopic connection with the rod end.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 98 words
In a corrugating machine, the combination comprising a. a series of longitudinally axially elongated rods and two generally parallel chains, b. means interconnecting the ends of the rods with chain links of the two chains so that the rod ends can swivel relative to the links to which they are connected, and including a universal joint between each rod end and associated link, the joint including a member having axially slidable telescopic connection with the rod end and wherein said telescopic connection is defined by a bore in the rod end, the member rotatably received in the bore.
Claim 2
Dependent Claim 98 words
In a corrugating machine, the combination comprising a. a series of longitudinally axially elongated rods and two generally parallel chains, b. means interconnecting the ends of the rods with chain links of the two chains so that the rod ends can swivel relative to the links to which they are connected, and including a universal joint between each rod end and associated link, the joint including a member having axially slidable telescopic connection with the rod end and wherein said telescopic connection is defined by a bore in the rod end, the member rotatably received in the bore.
Claim 3
Dependent Claim 44 words
The combination of claim 1 wherein said joint includes first and second parts having tongue and groove interfit, and a transverse pin interconnecting said parts for relative pivoting about a transverse axis normal to the longitudinal axis defined by said rod and said member.
Claim 4
Dependent Claim 28 words
The combination of claim 2 wherein one of said parts is integral with said member, and the other of said parts is removably connected with a chain link.
Claim 5
Dependent Claim 31 words
The combination of claim 3 including a stop shoulder on said one part and engagable with the end of the rod to limit axial penetration of said member into said bore.
Claim 6
Dependent Claim 101 words
The combination of claim 3 including a first vertical frame and means for swingably mounting said frame on a vertical axis, a second vertical frame and means for swingably mounting said second frame on a vertical axis and in confronting and spaced relation to the first frame, upper and lower sprockets carried by each frame in parallel relation thereto, and a pair of conveyors mounted on the sprockets so as to present confronting sections, the conveyors including said rods operable to change their angularity when the frames are swung on their respective axis and mounted to interlace at the confronting sections.
Claim 7
Dependent Claim 14 words
The combination of claim 3 wherein said parts are external of the rod end.
Claim 8
Dependent Claim 29 words
The combination of claim 6 including a stop flange on said one part and located in spaced relation to the rod end, said flange directly facing the rod end.
