To all whom it may concern.-

Be it known that LPHILo G. BLAIsDELL, a

citizen of the United States, and a resident of Bradford, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Bundle-Tying Machines, of which the following is a specification. My improved bundle tying apparatus is designed more particularly for tying bundles of kindling wood with wire bands, but is also intended for tying bundles of other articles.

In the accompanying drawings, Figure 1 represents my improved bundletying machine partly in side elevation and partly in sectional elevation. Fig. 2 is asectional elevation on line 00 0c of Fig. 1. Fig. 3 represents part of the machine as seen in, Fig. 1, partly in side elevation and partly in section, and shows the position of the clincher at the completion of the operation of tying a bundle. Fig. 4 is a horizontal section on line y y, Fig. 1, showing the parts above said line inverted; and Fig. 5 is a sectional elevation of the tyingmandrel detached from the rest of the apparatus, with a piece of the tying-wire. It is drawn to a larger scale.

The broken piece a, at the base of Figs. 1 and 2 is to be understood to be part of a follower on which rests the saucer consisting of two jaws b, in which the pile of wood 0, or other articles is placed to be compressed and tied, said follower being subject to powerful upward force to compress the bundle between said saucer and the stationary yokes d, and hold it while being tied with a wire band e, which is first laid in the jaws which are grooved as shown at f, Fig. 2, for receiving it, and then the pieces of wood or other articles to be bundled are piled in the saucer on the wire. The wire hangs from a spool g, above and extends down through the hollow mandrel h, mounted vertically over the center of the saucer in the horizontal supporting bars 2', j, so as to revolve freely. The bars '5 and j, are supported on the standards 75, set upright in suitable relation to the compressing saucer and yokes. In the lower and enlarged head Z of the mandrel is a short longitudinal slot m, extending from the side of said head to the central bore for the wire, and on the end of the head a cam n, is pivoted suitably to grip the free end of the wire placed in said slot firmly against the side of the part of the wire extending out of the mandrel and around the bundle, and hold the two parts of the wire for being twisted together. The'free end of the wire is to be so placed and gripped in the slot by the attendant when the pile is completed and the bundle has been pressed together. The wires are then twisted as at 19, Fig. 2, this being effected by means of the sliding handle nut q, arranged to slide down on the mandrel and having a spurs, or it may be screw threads engaging the spiral groove 25, in the exterior of the mandrel in the well known hand drill contrivance, the parts being so adjusted that one down movement of the nut causes the requisite number of turns for completing the twist of an effective tie. Then the twisted and tied band is to be separated from the connected Wire, for which the cutters u are provided, said cutters being formed on the ends of suitably bent levers pivoted at U, to the cross bar '5, and extended upwardly in the diverging prongs w, suitable for being wedged apart by the lower end of the nut at or about the termination of the movement of the said nut downward, so as to eifect the cutting of the wire at or about the upper end of the twist, said cutters being arranged to take effect on opposite sides of the twisted portion of the two parts of the wire directly below the cam 71. When the handle nut q is raised again preparatory to the next operation the springs a open the cutters again. After thus cut-' ting the tie free of the connecting wire said tie is to be clinched as shown at b Fig. 3, for which the clincher c is provided, said clincher being a kind of hook head of a sliding bar at on the curved prong e of which the tappet f of the handle nut q takes efiect immediately after the operation of the cutters to cause the head of the clincher to thrust forcibly against the side of the twisted tie and bend it down sidewise as shown in Fig. 3, the head being normally at one side of the wires 'of which the twist is formed as shown in Fig. 1, suitably to be forced against and over the twisted wires as shown in Fig. 3. The reverse movement of the clincher may be effected by the attendant, or by a spring or other device, After the clinching, the tied bundle is released by descent of the fol- ICO lower and is discharged; The attendant then grasps the lower end of the wire e, which is left as seen in Fig. 3, and pulls the wire down and adjusts it in the jaws of the saucer preparatory to making and tying anotherbundle. The sliding bar d of the clincher is in this instance represented as mounted by the slotted arm f on the studs g for sliding to and fro, but it may be mounted in any other approved way, and I do not limit myself to the form of hook headed clincher shown, nor to the arrangement and manner of operating the cutters, and the gripping cams may be variously arranged.

I claim- 1. In a bundle tying machine the hollow rotatable mandrel having the axial guide for the wire, a cam gripping device at the delivery end of the mandrel for gripping the two parts of the wire together, and means for rotating the mandrel in combination with bundle holding mechanism substantially as described.

2. In a bundle tying machine the hollow rotatable mandrel having the axial guide for the wire, a cam at the delivery end of the mandrel for gripping the two parts of the wire to be twisted, means for rotating the mandrel and cutters for separating the tied bundle from the wire, said cutters located at the mouth of the wire guide in combination with the bundle holding mechanism substantially as described.

3. In a bundle tying machine the hollow rotatable mandrel having the axle guide for the wire, means for gripping at the mouth of the wire guide through the mandrel the two parts of the wire to be twisted, the handle nut for rotating the mandrel, and cutters adapted to be automatically operated for cutting the wire by the said handle nut for operating the mandrel, in combination with means for holding the bundle substantially as described.

4Q In a bundle tying machine, the combination with bundle holding mechanism, of the vertical spirally grooved hollow rotatable mandrel having the axial guide for the wire, handle nut for operating it, and the pivoted wire cutters adapted to take effect on the twisted wires at the mouth of the wire guide of the mandrel, and having the divergent prongs subject to the action of the handle nut for operating them to cut the wires, directly following the twisting of the wires through the instrumentality of said nut substantially as described.

5. The combination with the wire feeding and twisting mandrel having the axial guide for the wire, the operating nut of the mandrel, and with the bundle holding mechanism, of the wire tie clincher adapted to be actuated by the mandrel operating nut substantially as described.

6. The combination with the bundle holding mechanism of the hollow rotatable mandrel having the axial guide for the wire, and the slot in the end for reception of the free end of the wire, the cam on the end of the mandrel for gripping the wires, and the handle nut for operating the mandrel substantially as described.
