Be it known. that Louis A. STEAUBEI.. a citizenI of the United. States, andresident of Green Bay? in the county of Brown tain new and useful improvements in Paper-Folding); Machines; and l do hereby (ieclarc that 'the Foiiowing is a iuii, ciear, and. exact description. thcrsoi 10 This invention relates to intesi-folding inan chinos and is particuiarly directeii to double, od, intciziifoiding machines which are adaphed to produce packages of intcri'olded sheets of paper. l5 The primary purpose' of this invention is to produce an interoiciing machins Whicii will hohl. the paper at each oid immediately a-L'L'ter the told has been produced, alici which 'will hold the central portionoif the 2c folded paper 'to prevent buiging or unfolding, thas adapting the machine 'to the filing' oi" eren the thinnest kinds oi paper such as toilet paper for instance.

in generai this invention is an improve- 25 ment over that disciosefi in .my United, States Patent Number 1,423,276 of July 18, 1922, for paper'foldingi'nachines and hasthe sanne. geneliai objects as those sst iiorth in the shove noteo patent.lx in addition "so so the, speciic objects enumerated; above.

Further objects src to provide an i.nter '.tfoidina; machine in which several ho'iding oeps-esser- .iaps and tuching bia-(ies arc operated in a regnisr manner hy extremely simple, mechanism having Vsry 'few parts., sncf; so formed`1 that 'ail or" the parts are rug vgsd and reishie sind are not likely to get ont of order. y hnrthsr objects are to provide an inific prot/eci. iorn of hoider plates for the folded paper which are so constructed that the paper is securely hehi against shifting, even at the time timing which the inici is maris, thus insuring the production of, a package is oi' uniform Width although formed of inten iioldcci separate sheets. 4

Furthsr objects ars to provide a machins for producing inter-foiciefi sheets oi' this psper in which a` combination olif iong and 5o short presser flaps :is employed, the former to hoid the okied portion of the paper ininieciiatciy after' ing and thc latter to hold :in intermediate portion of the Loioeci 'paper to prevent isengsgement of th@ inst im or loos@ Sh, and t0 'thus .keep such shect and. Statco "Wisconsinj have invented ce1.

An cmhociiment of the invention is shown in thc accompanying drawings, in windu-- Figure l is a 'fragmentary View of the rams and osciilsting mechanism therefor, and of the cani. folios/'ers showing in dotted lines the position of thc ifec. roiiers Figure y2 is an eie'vationai View hooking;n `in at the front of the machins, said View showing certain .or the parts in section for clcarness ci illustration. 4

The machine is of snhstantiaiiy the same form as that disclosed in my shove noted jpatsnt and the details ot the machins which ars similar to the patented strnctnrs nee/ii not therefore he iiereiops.

.in interiohing machines forming @srt of this inreniiong a crank shaft l is oro Viced Vand driven through the medium of a goar F2 connects-n with 'the :iced and. other ortions of the machins snel coirecti inefi therewith. 4
