SPECIFICATION forming part of Reissued Letters Patent No. 12,204, dated March-15,1904. Original No. 654,515, dated July 24,1900. Application for reissue filed June 30, 1903. Serial No. 163,829. I

Be it lcnownthat I, anew Dam: (Ynsrriw Lmrn acitizenot' the United States. residing at Los Angeles, county of Los Angels, State 1 of California, have-invented a ccrtair'tncw and ,useful Improvement in Paper-I olding Mal chines; and I declare the following to be a .full, clear, and exact description of the inven- ;tion,: i 1chas will enable others skilled in the art to which lt pertains to make and use the same, reference being had to the accompanying dra\\-'ings,wh1eh torn a part of this specilication. This IIIVQIIEIOII relates to paper-folding inachines', and has for its OlJJOQt an improved machine adapted to 'fold a number of long ribl bons of paper, givingto each ribbon a s ngle fold alongitslongitudinal middle line, and so arranging the consecutively tolded ribbons that each ribbon except the two outside ones embraces between itsadjaecnt faces the edges .oftwo adjacent ribbons of paper, one of which lies partly within and partly without on the one side and the other of which liespartly within and partly without on the other side. If thefold or? crease of each ribbon be considered a midrib and the portions of the ribbons of paper. at eacli side of the midrib be considered wings, then the consecutive ribbons of paper will take a positionsuch that if the first ribbon have the midrib upward and-the wi-ngs'turned downward the second ,a-"f wings turned upward.

ribbon will have the midrib down and the at the right of thegsecond ribbon will underlie the downturned wingat' the left of the first ribbon and th( upturned wing at the le'ftof the second ribbon] will underlie the downturned wing at the right ofthethird ribbon.

and the third ribbon will have its-m'idrib up.

ward and its wings, turned downward, so that the downturned right wing of the first ribbon and the .downthrned deft wing of the third' ribbon lie between, the upturned wings of the second ribbon; and the upturned right wing of the second ribbon andthe' upturned left The upturned Wing,

downturned wings of the third ribbon, and sol C on indefinitely for as many ribbons as-ma be desired. t

The machine which is shown in the drawings is adapted to crease and :fold twelve ribi bons at a time, sixof which are creased at the right end of the machine and six of which are creased at the left cngl of the machine, and the 5 5 two bundles of ribbo'ns'are engagedtogether,

sothat the last ribbon of onebundle engages with the first ribbon of the second bundle,

' and after being engaged together the bundles are cut and other bundles of ribbons drawn 0 fronrthe'right and left ends of the machine are la'ifid alongsidethe second bundle, and the assembling is continuous'until' a large niimb'cr ot' bundles have been brou'ght into the described relation. lhe resulting long bundle of ribbon is then cut into short bundles,each

one of, which contains a ni nnbcr. of rectangul lar and nearly-square sheets of pap'er, each.

of which sheets is'engaged withtwo adjacent sheets in the way described. The short bun- 7 dles of paper are placed in a box which is covered, ."and. the cover of which is provided with a central slit-that runs parallel to the i'olded edges otthe sheets of paper that are in the box. The end of one sheet of paper is pulled 7 5 throughthe slit, and when it is pulled farther through theslit and out of the box it draws with it the end of a second fsheet of paper, which is left projecting through the slit in the box. The paper prepared and-presented in 3 this Way can be drawn a sheet ata time from the box, but no faster. I.

In the drawings, Figure v1 is a perspective of the machine. Fig. 2 is a diagram indicating the position assurncdby the ribbonsof' 5 paper when partially folded. Fig. 3 is a dctail of, a drawing-die by which the paper is folded. Fig. 4: is a detail ofa head-block over which the ribbons are drawn. Fig. 5 indicates the position of the two parts of the foldingm'achine assembled at the ends of a table on which the'bundles of paper are gathered.

. The right and left endsof the rnachine are alike, and the two partsare united by-a trough in which the bundles of ribbons drawn from the right-end of the machine and those drawn from the left end of the machine are assembled and gathered during the progress of the work of'making the large .bundle mentioned.

dies are similarin construction, and each'consists of. an under die-block, (shown in det 'il in Fig. 3,) and the underdie-blOckhaS a numher-of serrations or teeth that rise above its surface. Hinged to the under block 4 is an upper block 3, which is 'also' serrated, and the serrations of-the lower block 4 engage in the notches. between the serrations of the upper block 3, andthe serrations ofthe upper block 3 engage in the notches of the lower block 4;. Thesurfacewt the serra'tion's'of the one partdo not, however, touch the surfaces of the serrations of the other part. The block?) is' hcld to block 4 by hinge 5 and by book 6, and

when'the two. parts ,of the drawing-die are closed together there is between thema corrugat'ed or wavy opening through which the I iribbons of paper are drawn. There 'arepref- "er-ably several drawing-dies, the outermost of. 'which has serrations with broad bases -and shallow notches and the innermost ofwhich;

I has serrations of narrow bases and deep notches, the intermediatedrawing-dies having serrations of. which the bases are narrower than the first and :less'narrow thanjthe lastf and the notches deeper than the'first and less deep than the last die- C, and each reel is provided with ajournal i that'is supported inbear'ings D' D. atthe end of the table I Preferably the bearings'are on an :arched support and are equally distant fromvertical guides H Hthatllie at the i'n-f .ner end of this section of therhachine. Be-

tween the"reel-supports D'and the first di Z the ribbons pass overheadblocks' E, E, E
