BALING-MACHINE.

Application filed. December 19, 1913.

To all whom it may concern Be it known that 1, CHARLES M. Ennis- LING,a citizen of the United States, reslding at Cleveland, in the county of Cuyaho-ga and State of Ohio, have invented certain .new and useful Improvements in Baling- Machines, of which the following is a specification.

This invention relates to baling machines and is especially adapted and intended for the purpose of bundling or baling bags, such as empty cement bags, but it is capable of other uses if desired.

The object of the invention is to provide an improved machine which will apply binding wiresto a bundle of bags or the like, the construction being such that a plurality of wires may be applied to the bundle at each operation, the ends of the wires being twisted and broken off by mechanical devices.

By means to be hereinafter described the bundle is first compressed and the wires placed around the same, by means of a pair of pivoted arms which also act as guides for the wire, and these arms place the ends of the wires between twisting jaws which are rotated by turning a crank, to twist the ends of the wires together.

I am aware that bundling machines for bags or the like have been used, in which the wires are placed around the bundle, and then their ends are twisted by pliers or the like, operated by hand. By means of the present invention the wires are applied and twisted by the machine, the use of other tools being unnecessary.

The invention is illustrated in the accompanying drawings in which- Figure 1 is a top plan view of the machine. Fig. 2 is a side elevation with the arms closed. Fig. 3 is a similar view with the arms open. Fig. 4: is an end elevation. Fig. 5 is a detail in section through one of the twisters. Figs. 6 and 7 are enlarged details of the twister jaws. Fig. 8 is a section on the line 88 of Fig. 7.

Referring specifically to the drawings, 6 indicates a stand or table, the top of which forms a bed for the bundle of bags or other material to be bundled, the bags being placed between

uprights

6 and 6 at opposite sides of the table.

7 indicates a pair of arms pivoted at one end to the uprights 6 and arranged to swing over to the uprights 6 These arms are Specification of Letters Patent.

curved to correspond to the shape of the bundle to be formed, and they are also grooved. on the underside, as indicated at 7, to receive the wire indicated at W. The arms are connected by a cross bar 15, from about the middle of which projects an arm 15 adapted to be engaged at its outer end by a hook 16 at the upper end of a vertically movable rod 16 connected to a treadle 17. Thisrod lfiworks through a guide 30 on the frame and is normally raised by a coiled spring 21 confined between said guide and a collar 22 on the rod. Each arm 7 is provided at its end with a fork 7 under or through which the wire is threaded, and which acts to place the ends of the wire between the jaws 9 and 9 of the twister which is indicated as a whole at 8. The fixed jaw 9 is attached to a rod 10 which is tapped into the hub of a pinion 12, mounted to turn in a bearing 31 at the top of a standard 6, the rod 10 being eccentric to the axis of the pinion. The movable jaw 9 is fixed to the front end of a rod 10, the rods 10 and 10' being pivoted together between their ends by lugs and a pivot pin 8 so that the j aw 9 may swing toward or from its companion jaw 9. The jaw 9 is provided with a latch 18 the outer end of which is beveled, and this latch works in a groove in said head, with a coiled spring 19 behind the same which tends to advance the latch across the space between the jaws. The movement of the latch is limited by the pin 20 working in a slot 20* in a cover plate 20 over the groove. The jaw 9 has a projection 11 at the lower edge thereof which by contact with the jaw 9 maintains a slot 32 between the jaws to receive the ends of the wire. As shown, there are two arms 7 and two of the twisters 8 and associated parts, to apply two wires to the bundle at once. The rear end of the rod 10 is beveled as indicated at 33, and 1% is a pin which extends through the axis of the pinion 12 and is provided with a wedge head 34 which works between the

rods

10 and 10 and when advanced or pushed in acts on the beveled end 38 to close the jaws. This rod 14 may be pushed in by hand or otherwise. The pinions 12 are rotated by means of a gear 1?) turned by a crank 13 attached to its shaft. The gearing is inclosed by a suitable casing 35.

In operation, the arms 7 are opened or thrown back as shown in Fig. 3', and the twisters 8 are so located that the slot 32 be tween the jaws 9 and 9 is presented upwardly. One end of each wire tie is threaded through said slot, and the wire is then carried around in the groove under the arm'7, with its other end between the fork 7 The pin 14: is then pushed in to close the jaws.

arms 7, and the latter are then swung down upon the pile. until the arm 15 is engaged by the hook 16 The treadle 17 is then depressed, compressing the bundle of bags by pulling down the arms 7, and this action forces the ends of the wires, guided by the under.

forks 7 into the slots 32 between the jaws, the catches 18 yielding under the pressure to permit the ends of: the wires to slipv there- These catches then hold the ends of the wires in the slots between the. jaws, then release the pressure on treadle and swing back the arms 7. The crank 1.3? is then turned, revolving the pinions 12 and the. twisters 8, and the ends of the wires between the jaws, Q and 95* are twisted around each other, thereby fastening the. ends of the ties together, and finally breaking 0d the super.- fiuous ends of the. ties.

The plates 9 and 9 are set at a slight angle so that the inner lower edges where the jaws meet are closer together than are the outer edges of said plates, this gives the jaws a cutting edge which causes the Wire tie to break ed at points coming in contact with these edges when the ends of wires have been sufiiciently twisted. It will be understood that these breaks will take place in the immediate end proximity of the tie wires, the cutting edges nipping off the ends of said wires. It might be further explained in this connection that the ends of the baling wires are bent in such a manner as tov form a small knot, which is for the purpose of holding the wires securely, one end in the forks 7? and the other end in the slot 32 oi the jaws formed by plates 9 and 9 After the end of wire in fork 7? has been delivered into the jaws of twister, the knotted ends of said wires extend just be.- yond the inner edge of the, jaws and it is at this point that the ends of wires are clipped oil" by the cutting. edges of said jaws. The jaws can then be opened by retracting the, pins 1.4-. and the clipped ends of wire which may adhere between the jaws will fall out. The bundle of tied bags may now be, removed and the machine is ready for the neXt operation.
