Abstract
Abstract An open end carrier construction for conveying folded paper or paper-like slips between terminal stations in pneumatic tube systems. A hollow carrier body is formed with open ends, one end of which is closed by a disc and cap. The carrier body is doubleconcave and forms a narrow inner passage or slot intermediate the carrier ends through which folded slips extend and in which the slips are securely gripped when inserted in the carrier body through the uncapped end.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
104 words
Pneumatic tube system carrier construction including a hollow carrier body terminating in front and rear ends, one end of which is open; the carrier body having top and bottom concave walls and hourglass-shaped side walls forming a narrow, laterally elongated, generally central, oblong passage portion intermediate the carrier ends; and said carrier body having an increasingly larger oblong cross-sectional shape toward either end beyond said oblong passage portion; wherein a folded slip of material inserted into the body through the open end is retained within the body and is gripped at said narrow central oblong passage portion by the top and bottom concave walls.
Claim 2
Dependent Claim
104 words
Pneumatic tube system carrier construction including a hollow carrier body terminating in front and rear ends, one end of which is open; the carrier body having top and bottom concave walls and hourglass-shaped side walls forming a narrow, laterally elongated, generally central, oblong passage portion intermediate the carrier ends; and said carrier body having an increasingly larger oblong cross-sectional shape toward either end beyond said oblong passage portion; wherein a folded slip of material inserted into the body through the open end is retained within the body and is gripped at said narrow central oblong passage portion by the top and bottom concave walls.
Claim 3
Dependent Claim
114 words
Pneumatic tube system carrier construction including a hollow carrier body terminating in open front and rear ends and having concave top and bottom carrier walls and hourglass-shaped side walls forming a narrow, laterally elongated, generally central, oblong passage portion within the carrier body between said top and bottom walls and intermediate the ends; the carrier body having an inCreasingly larger oblong cross-sectional shape toward either end beyond said narrow oblong passage portion; and removable closure means for the open rear end; whereby a folded slip of material inserted into the body through the front open end is retained within the body and gripped by the top and bottom walls at said narrow passage portion.
Claim 4
Dependent Claim
114 words
Pneumatic tube system carrier construction including a hollow carrier body terminating in open front and rear ends and having concave top and bottom carrier walls and hourglass-shaped side walls forming a narrow, laterally elongated, generally central, oblong passage portion within the carrier body between said top and bottom walls and intermediate the ends; the carrier body having an inCreasingly larger oblong cross-sectional shape toward either end beyond said narrow oblong passage portion; and removable closure means for the open rear end; whereby a folded slip of material inserted into the body through the front open end is retained within the body and gripped by the top and bottom walls at said narrow passage portion.
Claim 5
Dependent Claim
27 words
The carrier construction defined in claim 2 in which the open front end is generally rectangular in shape and the open rear end is circular in shape.
Claim 6
Dependent Claim
61 words
The carrier construction defined in claim 2 in which an annular collar surrounds the carrier open rear end and is formed integrally with the carrier body; and in which the collar has a rear edge which projects outward from the carrier body; whereby the end closure may engage the collar rear edge to secure said closure means to the carrier body.
Claim 7
Dependent Claim
53 words
The carrier construction defined in claim 4 in which a shoulder is formed within the collar; in which a disc complementary in shape and size to the collar and shoulder is telescoped within said collar and seated upon the shoulder; and in which the end closure means retains the disc within the collar.
