PAPER-BAG MACHINE.

SPECIFICATION forming part of Letters Patent No. 333,646, dated January 5, 1886.

Application filed June 1G, 1884.

To aZZ whom it may concern:

Be it known that I, WILLIAM A. LORENZ, of Hartford, Connecticut, have invented a new and useful Improvement in Paper-Bag Machines, of which the following description and claim constitute the specification, and which is illustrated by the accompanying two sheets of drawings.

This invention relates to the former of that part of a paper-bag machine which continuously manufactures a tucked paper tube from a continuous roll of paper.

That part of such a machine is elaborately shown in Sheets 3 and 4 of the drawings of an application for Letters Patent of the United States for a new and useful paper-bag machine led in the Patent Office by YVilliam A. Lorenz and Villiam H. Honiss, May 15, 1884, and is fully described in that application.

Not all the features of that part of such a machine are shown in the drawings of this application, nor are all the features which are shown in these drawings described in this specification, because the present invention relates to one portion only of that part of such a machine.

Figure 1 in the drawings is a cross-section of the tucked paper tube above mentioned. Fig. 2 is a plan View of my new former and of the adjacent parts of a paper-bag machine. Fig. 3 is a side View of the same. Figs. 4, 5, G, and 7 are cross-sections ou the lines NV W, and X X, and Y Y, and Z Z, respectively, of Figs. 2 and 3. Figs. 8, 9, and 10 are crosssections on lines X X, and Y Y, and Z Z` respectively, of Figs. 2 and 3, but showing a slight modiication of the form of the interior of the former. Fig. 11 is a plan view of another modiiication of my new former and of the adjacent parts of a paper-bag machine. Fig. 12 is a side view of the same. Figs. 13, 14, 15, 16, and 17 are cross-sections on the lines R R, and S S, and T T, and U U, andV V, respectively, of Figs. 11 and 12.

A is the rectangular part of the former. Under it are the roll B, the roll C, and the pressing-roll D, all three of which are identical in construction, mode of operation, and

function with the corresponding parts of the apparatus shown and described in the appli- 5o' cation of William A. Lorenz and William H. Honiss for Letters Patent of the United States for improvements in paper-bag machines iiled on the same day with this application.

E is the hollow part of the former, placed between the rectangular part and the drawingrolls F and G.

H and I are projections on the sides of the interior of the hollow part of the former. These are curved longitudinally, as shown in 6o Fig. 2, and they gradually increase in depth, and decrease in thickness at the base as they approach the drawing-rolls. At the extreme end nearest the drawing-rolls I prefer those projections thicker at their edges than at their bases, as shown in Fig. 7. i

The modiiied former shown in cross-section in Figs. 8, 9, and 10 differs from that shown in Figs. 2, 5, 6, and 7 only in being without the projections H and I. 7o

The modiiied former shown in Figs. 11 to 17, inclusive, differs from that shown in Figs.

2. 5, 6, and 7 in having its rectangular part much shorter, and its hollow part much longer, and also in having the form ot' its hollow part 75 somewhat different in cross-section, as shown in Figs. 11, 12, 14, and 15. That difference in cross-section consists in extending the projections H and'I on substantially the lines shown in that behalf in Fig. 11, and also in 8o making a cavity, J, for the accommodation of the borders of the paper before those borders are pasted together.

The mode of operation of this invention is as follows: The drawing-rolls F and G continuously pull the tucked paper tube out of the smaller end ofthe hollow former E, that former operating to give the tucked shape shown in Fig. 1 to the rectangulartube made by the rectangular former A shown in Figs. 2, 3, and 9o 4; or, if the modification of my invention shown on Sheet 2 of the drawings is used, then the drawing-rolls F and G operate as before, and the hollow former E not only operates to give the iinal tucked shape to the paper tube, but also operates to bring the` borders of the paper together, and thus causes the line of paste Vertical expanse continually diminishing from to make them permanently adhere to each one end thereof to the other, substantially as other. described.

I claim as my invention- WILLIAM A. LORENZ. 5 The hollow former E, open at both ends, Witnesses:
