CHABJLEE PURE, GE H63? i To all whom it 'may omieero:

Be it known that L (li-reame wora, a citizen of the United States, residing at Holyoke in the county of i'iazfipfien ami State ofg Maesaehusette2 have invente an improvement in Machines for Paper, of which the oiiowingg ie a speciiioa tion.

This invention has for its ohgieo't vision of pneumatic means which *my be applied to the ordinary ilo-uririni apermakingl machine5v to antoinaticaii] cari-5I across the end-portion of the web rorn the paperznaking wire to the iirst feit. @rtiinai-ily this operation has 'been Inanuafiiy performed. marinai carrying-over o?? the end-portion of the web reqnireeahighiym trained operative, het the automatic carri ing-over mea-ns involving my present iovemn tion can be set in.v operation other 'than a highly dexterons workmen This means embodying this invention has the great advantage of being enea to man ua/cture, and easy to apply to ela ang inaomnes.

In accordance with my inventiony means adapted to oreibiy deiiver a giet' air or other gaseous sniosfsanee, iii the form of a sheet, is arranged riireot said air agaiiis'c the Wire at one end theneo' win "i acte to detach the enfiportion of the weo rom the Wire and conjunction with 'the moroni-itum which is given to said enfioortioii 'by the moving Wire, conveys it a inw tervening space to 'the feit. his jet is applied to the Weo at poi i. vf ere the Wire makes its turn Aaround 'the' coiieiioii; around which the Wire passes, the coueiiy thua forms a baeiring or ahntiiient for the air, which assiste in When the web has been moved 'to 'the eii, the end-portion of 'the web is snostantiaiiy parallel to the felt and has a velocity substantially equal. in value and direction to that of the feit, andA1 therefore, the web is transferreol to the feit Without the creating of stresses tending to the web.

v my invent-ion, 1 ami. 2 represent the Couch* relisD couchroil 2 in the iilostration being the emi-rolf'. over or around which the paperinaiiing wire 3 passes. 4 represents one of the roils overv or around which the fel, 5, ordinarily caiied the firs felt? passes. 5 repreeen'e toe nenai Webelitter, which is einpioyoi to eiit the Yweb so as to form a narrow-eiidportion which subsequently may be Lidened to the ioii Width of the web. This cndqiortion is ciesigne 'to he cietacheci from what may' oe termeii the end of 'the Wire and carried across the intervening space to the rait. n high. speed nriachines9 this is a di'iiicnit task to be performed lman nelly, and the higher the speed, the more diieoi ber/eines Tthe task. The tendency is at the preeent time to greatly increase the speefi of theee machines, henoe the provision of aiitomatie means to perform ibis work. ie of acivantage. in view of the fact that many machines of thie type are now in. nee9 and that they are very expensive to inanefemore7 it ie a great advantage to devise automatic earrying-over means which may 'Koe appiied no existing; machines.

The automaeie carrying-over device, eene bofiying thie invention, has these qualities, and consists of a hollow shell orcase 10, aaiapteii for connection with an air orother gaseous unifier prsure, and having a delivery-end arranged to deliver a jet of or other gas in the forni of a thin sheet oi' the desired Width. Said device is arranged adjaoent the conch or other enfiV-roii 2, over or around 1(which the Wire passes, and its (ielivery orice is arranged to direet Said sh ,et in an upward (infection)g suo stantiaiiy tangentialV to the cylindrica sureee of the couch or other endroii about which the paper making Wire turns, although its angle with respect to said couchroli maybe varied more or less. The air or other gas which is forcibly delivered in a direction opposite to the movement of the Wire anfl paper forces its Way between the wire and paper and acts to detach the emi portion of the web from the wire, and to support said enfiportion in an elevateti position and in conjonction with the momenM torn imparted to it 'by the moving Wire, carry it across the intervening space he tween the wire and the felt, so that itv will engage the moving feit.
