Patented June 23, 1931 UNITED STATES HUGO BRTININGHAUS, OF BABMEN-WICHLINGHAUSEN, GERMANY METHOD OF AND APPARATUS FOR TYING PACKETS Application filed September 21, 1929, Serial No. 39 1,27 1, and. ineerman September25, 1928.

The invention relates to a method and an apparatus for tying packets and the like by means of wire or metal strips. The application of wire in tying chests or cases offers no difiiculties. In tying pasteboard packets or paper envelopes, however, the danger exists therein that the edges of the packet or enmeans of wire or metal strips, thin steel angle 9 pieces or bars are placed on the edges of the packet according to the invention which angle pieces or bars take upthe pressure exerted by the wire or metal strip merely dur ing the tyingoperation and are withdrawn after this operation has been terminated.

The protection afforded to the packet dur-' ing the tying operation by the steel angle pieces or bars enables the use of wire or metal strips of much greater thickness and of a hardnessso as not to expand. In spite of i this great hardness, with the present method the wire or strip can be placed onto the edges of the packet more tightly and at more correct angles.

The steelangle pieces or bars further may be shaped and applied so as to give way about as much as it corresponds to their thickness, so that after their removal the packet is so tightly tied as if tied without application of the angle pieces or bars. 1

In order that the invention can be more easily understood, an embodiment of amachine adapted to carryout the present meth od is diagrammatically illustrated in the ac-" companying drawing inwhich Figure 1 is a side view of the machine, Figure 2,is a front view thereof, 1 Figure 3 is a front view showing a modified form of the machine permitting adjustment for different packet sizes,' and a in such a manner that the steel angle pieces Figure 4 is a lateral View of Figure 3.

Referring. to these drawings, 1 denotes the supports interconnected by cross bars 2 and 3, so as to form'a stationary frame and having mounted thereon angle irons 4 and 5 which form rails for a frame 6 adapted to run thereon. The lower bars 5 on their rear ends carry stops 7 for the frame 6. On their front ends the rails 5 converge into fiat guides 8 that form a support for the packet 9. .16

I The movable frame 6 possesses rollers 10 interconnected by longitudinal bars 11, crossbars 12, and vertical supports 13, so that a box-shaped carriage is formed which can be shifted along the rails 4 and 5. This shifting 5 motion of frame 6 is exerted by means of a hand lever l l fulcrumed on apin 15 of an upper longitudinal bar 16 of the stationary frame of the machine. Lever 14 has a handle 17and is hingedly connected on its other end 5% tov a further crossbar 19 of frame 6. On another lower cross bar 20 of frame 6 is mounted a'hook 2l'having attached to it a cord 22 running on a pulley 23 mounted on a cross bar 24 fixed on the rails 5. Cord 22 i carries a weight 25 and tendsto shift frame 6 to itsforemost position. V

In this foremost position of frame 6 guide bars 26 which extend in the prolongation of the longitudinal bars 11 abut on the edges of :53 the packet 9 and in this position can be applied to the latter by the tyingmeans denoted by 2 As soon as, the tying means 27 have been applied, frame 6 is withdrawn by means '01": if hand lever 14:. When this takes place, stops 28 and 29 rigidly connected to the supports .1 come to abut both on the tying means and on the rear surface of the packet. The latter and the tying means 27 are thereby-pre-- i vented from taking part in the rearward motion of frame 6. The tied packet 9 thus re mains on the bars 8 from which it can be easily Withdrawn.

The stops 28 and 29 may be designed so as to be adjustable for different packet sizes, this arrangement, however being not shown for the sake of clearness.

fFurthermore, the machine may be designed or bars are stationary and the packet is moved out of the machine by frame 6.

In order to adjust the bars 26 for different packetsizes, a movable frame may be used as illustrated in Figures 3 and 4. The rollers of this frame are mounted on rings or any other suitable member which rings carry adjustable levers 31 pivoted on pins 32 and adapted to be fixed in the adjusted inclined position by means of clamp screws 33 guided in slots 34: of the rings 30, all as clearly shown in Figures 3 and 4. The levers 31 further carry longitudinally shiftable sleeves 35 adapted to be fixed on them by clamp screws 36 and carrying in their turn sleeves 37 which extend normally thereto and commonly carry the respective bars 26. By means of the clamp screws 38 the bars can always beset so as to correctly abut on the edges of the packet.

The movable frame as illustrated in Figures 3 and 4 may be used likewise in connection with the stationary frame fitted with the rails 4, 5 as illustrated in Figures 1 and 2. Of course, in other respects the construction of the movable frame 6 may be any other suitable one.
