PHILIP JEHLE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO MARTIN NIXON AND WILLIAM H. NIXON, BOTH OF SAME PLACE.

FORMER FOR PAPER BAGS.

SPECIFICATION forming part of Letters Patent No. 329,173, dated October 2'7, 1885.

Application filed December 2:2, 1884. Serial No. 150,976.

To all whom it may concern.-

Be it known that I, PHILIP J EHLE, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Formers for Paper Bags, of which the following is a specification;

My invention consists of a former, fully de scribed and claimed hereinafter, for creasing and folding a tube of paper prior to converting it into a bag.

In the accompanying drawings, Figure 1 is a perspective view of my improved former for paper bags; Fig. 2, an end view of the same looking in the direction of the arrow; Fig. 3, a view illustrating the mode of applying a tube of paper to the former; Fig. 4, a transverse section of the tube when it is pressed to the sides of the former; Fig. 5, a perspective view illustrating the progress of the tube over the former; Fig. 6, a transverse section'of the tube after it has left the former; Fig. 7, a view of the tube distended, and Figs. 8 and 9 views illustrating modifications of my inven- "tion.

The former, which is shown most clearly in Figs. 1 and 2, consists of an oblong plate, A, and two vanes, a a, attached one to one side and the other to the opposite side of the plate, the whole being preferably made of sheet metal. Each of the vanes is of triangular shape, the outer edge beinginclined in respect to the plate and merging into the face of the latter at m.

A tube, B, of paper to be converted into a bag is placed over the cruciform end of the former, as shown in Fig. 3, and as the tube is moved in the direction of the arrow the paper is pressed against all sides of the plate A and its vanes a a, so that the tube temporarily assumes the cruciform character shown in Fig. 4. As the movement of the tube is continued the portions which are pressed against the vanes gradually cease to be controlled thereby, and can be folded down, as shown in Fig. 5,

(No model.)

so that when the tube is withdrawn from the 5 former it will be in the folded condition shown in Figs. 5 and 6.

WVhen the tube is distended, as shown in Fig. 7, it will be of quadrangular shape, with a crease, indicated by a dotted line, on each of its four sides, and will be ready for conversion into a square or satchel bottomed bag.

While the above operation can be performed by hand, I propose to embodythe former in a machine by which the creasing of the tubes by the ends of the former and the operations for completing the bag will be effected automatically, this machine to be the subject of a separate application for a patent.

The former described above is intended for square bags, and the vanes are directly opposite each other. When a bag-blank of oblong section, as shown in Fig. 8, is required, the vanes are arranged out' of line with each other, as shown in Fig. 9, and in order that the fornier may be adjusted for creasing tubes for bags either square or oblong in section I prefer to make the vanes laterally adjust-able on the plate A, this opportunity for adjustment being effected in the present instance by making transverse slots h h in the plate and securing the flanged edges of the vanes by bolts passing through the slots.

I claim 'as my invention- 1. The within-described former, the same 7 5, consisting of a plate, A, and triangular vanes combined with the plate, substantially as set forth.

2. The combination of the plate A with vanes a a laterally adjustable on the plate, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence oftwo subscribing witnesses.

I PHILIP JEIILE.

HENRY BOSSERT, HARRY SMITH.
