TO ALL WHOM IT MAY CONCERN:
Be it known that I, GUSTAV L. JAEGER, of 178 Fulton street, in the city, county, and State ot' New York', have invented a new and improved Paper-Bag Machine; and I do hereby declare that the following is a full, clear, and exact description thereowhich will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming a part of 'this specification, in whichi Figure 1 represents a transverse vertical section of this invention. l*
Figure 2 is a planer top view of'the same.
Figure S'is a detached plan of a bag when inished.
Similar letters of reference indicate like parts.
This invention consists in the arrangement of a movable former made of tin or other suitable material, in combination with two or more movable iin-ps or wings, which turn the blank over the former in such a manner that by the former itseli` the blank is heid in position, and a triangularpor square paper bag can be made with little trouble and expense. Tbevorrner is provided with a ridge, at those parts where the edges of the blank are to be joined, in snch'a manner that a pressure'is exerted on those'parts which are'tobe joined, and the ,operation ot' folding the blanks and securing their edges or ends is effected with ease and facility.
A represents a table, to the top of which is secured the formerB. This former is made of a thin 'piece of sheet metal, and itis connected to the table by suitable hinges a, and' springs b, which have a tendency to turn the same up in an inclined position, so that the blank can be conveniently introduced under said former'.
Behind the former is the gauge C, which is secured to the top of the table by screws 11 passing downithrough slots c, so that said gauge can be adjusted according to the size of the bags to be manufactured. After the blank has been adjusted under the former in the desired position, its edges are folded up, one after the other, in proper succession, by means'otl wings or iiaps D D which are hinged to the top of thev'table A, and operated by treadles E. The connection between said ila-ps and the table is made in such a manner that the aps have a tendency to open automatically, either by the action of springs, or by suitable weights, whenever the Vpressure of the foot on the corresponding treadlc stops. For triangular bags," the shape'of the former must, of course, be made triangular. 'The blanks are cut out square, and one edge of each blank is gummedprevious to introducing the same into'the machine. One blank after the other lis then placed on the table A', and under the former, one corner of said blank being held in contact with the gauge as shown in red outlines in iig. 2. After the blank has been thus arranged, the Hap D is made to turn up, then.. the outer corner is folded in by hand,`
and finally the ap D is made to turn up, and the gummed edge of the blank is made to adhere to the opposite edge, so that the bag is completed. To insure the gummed edge coming in contact throughout its whole length with the opposite edge, the former is'provided with a ridge,f, (see fig. 1,) and the ilap D is furnished at its lower surface with an elastic pad, d. A. notch, e, out in one edge of the former, enables the operator to take hold of the bag, after the same has been nished, and to remove the same from the former With ease and convenience. :For square bags the shape of the former has to be changed, and an additional folding flap has to be added.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent- The former B, in combination with the table A, gauge C, and flaps D D', worked and operating substantially as'and for the purpose described.
Also the notch e in the edge of the former, to facilitate the operation of removing the finished bags from said -fermer, as set forth.
