CARRIER FOR PNEUMATIC DISPATCH SYSTEMS Filed Sept. 2, 1951 "-INVENTOR ATTORNEY VICTOR H. JAcKsb/v f Patented Man, 28, 1933 UNITED STATES PATENT vIcironv n. JACKSON, 01* METUCHEN, NEW JERSEY, Assieivon so ivnw yonx srocx EXCHANGE, orivnw yonx, N. 11;"

CARRIER ron PNEUMATIC 'nrsrn'rori 'sarsr azirt s Application filed Septerhher 2,}931. Serial No. 560,697. j

This invention relates to an improved form of carrier or" container for'pneumatic dispatch systems in which papers and other small objects are placed in a carrier or container which is transported from place to "place infa system of tubing maintained'under a suitable airpressure, 1 j The use of carriers fabricated from metal, fibre and other materialshas been proposed for these systems and undercertain special conditions suchcarriers have been more or less satisfactory in operation, but Where a large number ofsuch carriers are-required their cost has been prohibitive. In certain other installations, particularly where the carriers are necessarily small and vast quantities of them are necessary, the difficulties attending the use of such carriers haveren dered their use impracticable. These{con-. tainers have heretofore been constructed of e such material that when the carrier is subjected toan'abnormal force, in any manner, it may be, and frequently is,per1nanently deformed. ,Thus a carrier may fall upi on thefioor, and being unnoticed, is stepped upon so as to deform the carrier slightly and make it depart fromits essential cylin-' 'drical cross section. Although this deformation may be so slight as not to be not1ceableupon a hasty examination, it has been p found that when such a carrier is again placed in the systeniit frequently becomes 7 jammed somewhere in the dispatch tubes, and temporarily,'at least, renders that por- 735 tion of the system inoperative and may re sult in considerable lnconvenience and expense. Needless to say,-this' expense isVastly greater than the cost of the'partlcular carrier causing the trouble,

" 40 Heretoforeit has been thought necessary to'provide the ends of'the'carrier With'felt or similar materialadapted'to contact more or less firmly With the inside surface's'of the tubes so as to prevent the passage of air around the carriers, and provide bearing surfaces While keeping the central portion of the carrier of such diameter as would permit it to pass around bendsin thetubes. A binding material is generally used to keep the felt'inrpositionon the carrier: It will i which, as 'before'xsta'ted," may be, and prefless diameter than the inside diameter of "the dispatch tubes. The diameter ;:and length of the-body portion andof thecar-v sharpestfbend in the system;

be appreciated that the construction of such .carriers entails" considerable expense and that a carrier of cheaper fconstructionaand .7 resultlngg in a savmgf noperating' expenses desired. p j

Therefore, the principal objecfio'f thepre"s{ 1 ent invention is" to provide a] unitary carrier of material which does not retain a"perma nent deformation when subject to abnormal and drawing in which a =1 Fig. 1 is a perspective vieW of apreferred embodiment of the invention, a

Eachband acts as a seal to prevent the passage of air between the end portions 2 and theinside surfaces of the dispatch tubes. As shown, the width of each band preferably corresponds with the length of theend portions 2 and thus 'more effectively-prevents leakage ofthe air, beyond the carrier when it travels around a bend when only the extreme ends of the carrier maybe in contact with the tube." 1

A hole 4 of relatively large diameter extends almost, through, the, carrier, leaving only a thin wall or closure 5 formed integrally with the otherparts oi'the car rier, and thus providing therequired space for; the articles to be transported. The

bandsB, of the twoends may suitably be dis-., tinguished by some. external. characteristics,

such ,as icolor, so that the two ends: of: the carrier may be; readily distinguished at a glance Thus the band adjacent the open end ofthe carrier may be red, for; example,

and the band at the closed end white so that the operator in picking up a carrierwhich is, lying on its-side may always place the open endinpositionto receive a slip.

It will .be readily understoodbyone-skille inf the artithat a- ,woodenacarrier of this,

form may be; very easily and cheaply made in. a few operations-and that-being constructed, ofwood, it will not retain apermanent deformation when subjected toap'ressure-but diameter" may be approximately 13/16 a while theoverall length of the carrier may will either return to itsoriginal. form or, if the force applied be large enough, be
