' FOLDER i on cnosme Tim ENDS-0'1? PAPER SHELLS.
To all whom it may Be it known that 1, JOHN OHnsNnY, a citi-- men of the United States, resi is afull, clear, and exact description, refer-' ence beingi had to. the accompanym drawform a part of this speci cation.
whic T he invention relates to devices forfolding or, crimping the. projecting ends\of shellsformed'on; the rotating mandrel of a shell machine for the purpose of closing the ends thereof. I
The object 'of the invention is to so construct the folder that the sheet from which the shell is formed will be so folded that one or more series of folds will be tucked'i'n beneath another series .of folds in order to more securel been 0 d to. attach to a wheel, secured to a;
close the end. Heretofore it has rotating shaft, a rotating folder or crim er comprising a lurality of radially extending fingers, s aced apart, adapted in their rotation, an during the rotation of the mandrel and the formation of the shell, to successively engage. the ed e of the paper rojecting beyond the man rel and form a p urality ofsucces'sivel overla ing triangular shaped folds. This orm of fb lder is extremely sunple in construction and effective in operation, but the foldin effected thereby is found to be more or ess insecure, and the more specific object of the present invention is to modify the construction of the folder of the character above set forthg'for the purpose of effecting the more certain and tight closure of the end of the shell.-.-'. This object is effected by means of a folder. or crimper folder ustrated in the accompanying draw-.
hereinafter described, in wh1ch i @iguresl, 2 3 and 4 each represent aside view of the folder in association with means for rotating the folder, the mandrel, the feed table, and the paper sheet-forming the shell,
Specification of Letters Patent. Application filed February 24, 1908. Serial No. 417,462.
Patented Dec; 8, loos.
lace the sheets ,of paper successively deivered to the rotating mandrel b, which isshown as turning 'in bearings c secured to the machine framed. Also-secured to the machine frame is a bea e in which turns the ear wheel to which 1s secured the folder.
a represents the feed table upon-which are.
he gear w eel f and the mandrel b are each actuated to continuously rotate by means of connections from .the main driving shaft, said connections not being shown nor de-' scribed, as they form no partof the invention.
The folder or crimper consists .of a plate 9 secured to and projecting beyond the periphery of the gearwheel The plate 9 is pro vided with two series of crimping fingers, the series h comprising seven fingers s aced apart and the series '1 comprisin spaced a art, the two senes of separate one from another by asubstantially greater space than'separates adjacent fingers of thesame series. Thefingers all project in a substantially radial direction rom the shaft of the gear wheel f and are so located with respect-to the mandrel that in their travel they successively 'ass close'to and in front of the forward emf drel.
In 0 oration the mandrel and .folder are rotate in the direction indicated bythe arrows. The sheets of paper 1' on the table a are successivel fed forward to the mandrel by means not s own, .and are preferabl held against the periphery of the mandrel uring rotation by means of air suction applied to four ger's gers being.
of the manthe interior of the mandrel, this suction be- I ing effective to so hold-the paper b means of I the perforations b' in the mandre The rotation of the mandrel and the rotation of the folder are so timed that, at a predetermined time after a sheet starts to'be wound npon the mandrel, the first finger of the series of fingers h will engage the forward edge of the paper sheet projecting beyond the forward en of the mandrel and form the initial fold, as shown in Fig. 1. In the continued rotation of the mandrel and the folder, the re- .maining fingers of the series ofifingers It will successively en age the edge of the paper sheet, thus ben ing it into a series of short, overlapping crimps or'folds, as illustrated in Fig. 2. 'As the folder and mandrel continue to revolve, the remainder of the paper sheet loo I time that the side edge ofthe paper reaches the mandrel, and this finger conseifiuentlya acts upon the corner of the aper she caus ing it to be folded in upon t e to of the series of folds formed by the fingers as shown in Fig. 3. Continued rotation of the mandrel andfolder causes the remaining fingers of the series of fingers i to act 'upon the over-' hanging forward end of the shell to bend it into a series of short, overla ping crimps or folds that bury or confine t e corner of the pa er sheet last fed to the mandrel, as shown m fiig. 4. Thus the end of the shell is securely folded or crimped by means of two or more series of overlapping crimps or folds, while the corner of the sheet last fed-to the mandrel is confined beneath the overlapping folds of the latter series, the effect belng to form What is ractically a double or triple bottom, thus fifilding in the end of the shell so securelythat there is no danger of its be coming accidentally opened in subsequent use.
Having now fully described my invention, what I claim and desire to protect by Letters Patent is:
1. A folder'for crimping the ends of paper tubes, comprising a rotatable plate provi ed with two series of fingers projecting therefrom, one series being separated from the other series by a substantial space. V 2. A folder for crimping the ends of pa er tubes, comprising a rotatable plate provi ed with two series of fingers projecting therefrom, adjacent fingers of each series being spaced apart and the two series of fingers'being separated by a space substantially wider than the space between adjacent fingers of the same series. v I 3. In a paper shell machine, the combination with a rotatable mandrel, of a rotatable shaft, 'a plate, carried by the shaft, provided with two series of fingers extendin substantially radially of the shaft and a apted, in the revolution of the shaft to travelinfront of, and in close proximity to, the'forward end of the mandrel, the two series of fingers being separated by a substantial space.
4. In a papershell machine, the combination with a rotatable mandrel, of a plurality of series of fingers and means to cause the same to pass successively in front of, and in close proximity to, the forward end of the mandrel, adjacent series of fingers being separated by a space substantially wider than the space between adjacent fingers of the same series.
In testimony of which invention, I have hereunto set my hand, at Paulsboro, onthis 3rd day of'Feby., 1908.
