To all whom it may concern:

Be it known that 1, JAMES M. LEAVER, Jr., a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented a new and useful Automatic Bundling and Tying Machine, of which the following is a specification.

The invention relates to an automatic bundling and tying machine An object of the present invention is to provide an eflicient machine designed for bundling and tying cut lumber and various other materials, and'capable of automatic operation to form bundles of uniform size, to bindthe bundles with wire and tie the ends of the wire-without overt-axing the ,wire or distorting the same or putting undue tension on any part of the band or knot so that the terminal strain will be not greater in the knot than elsewhere on the wire, and there will be no liability of weakening or breaking the wire. An additional object is to provide a novel knotting mechanism, one which differs from all others in coiling one end of a wire about a sect-ion of the wire, and which insures a tight knot such that no amount of strain can untwist. provide adjustable mechanism for auto matically engaging apredetermined amount of relatively incompressible material in a magazine, removing it therefrom and resenting it in bundle form to the bin ing means, and binding the material under a constant tension without slackening or loosening the bands, therebyinsuring a compact and perfectly formed bundle when non-expansible or inelastic material is handled. It is also the object of the invention to enable bundles to be tied with any desired number of bands spaced the proper distance apart, and to bind and tie the bundles tightly Without either drawing the wire over the material and injuring the same, or allowing any slack afterjthe knot is tied, thereby making a firm, compact and strong bundle. Furthermore, the invention is de-' signedito provide a machine in which no skill is required in tying the bundles-and in which there will be no danger of breaking the wire by reless operation of the ma (him The machine of the present invention is fundamentally designed to bind material of an inexpausible and incompressible nature,

the binding is completed and the com- A further object is to" compressing the material and afterward allowing it to expand againstthe binding elements. The resent application is limited to means for inding and-tying definite objects, examples of which area bundle of shocks, a box, and the like; Baling presses take bunches of loose material and pack them in layers in a bundle-formingchamber, which also constitutes the bindin chamber. lVhen the bundle is complet pressed material expands against the. loose bands to form the bale. The present invention takes bundles or articles of a predetermined size and sha ties them without changing their size and shape. The mechanism for fo the bundles shown in the accompan lugs and described below is in act a separate and distinct invention capable of embodiment in a separate machine and forming no rt of the present invention. The materiaf bi' article to be bound by m machine is an entity before it is move into and binds and (the binding chamber, and mecwarily so since the present machine pushes the material or article against .a wire or wires maintained under a, considerable and co stant tension.

The invention will behest understoodv from a consideration of the following detailed description taken in connection with i the accompanying drawing forming part of this specification, with the understanding, however, 'that the invention is not confined to any strict conformity with the showing in the drawing, but may be changed and modified so long as such changes and modifications mark nomaterial departure from the salient features of the invention as expressed in the appended claims.

The front and rear transverse beams are connected at their ends by side longitudinal beams 2 and 3, and at a, ,point between their ends by an intermediate longitudinal beam 4. See

Figs, 4 anl 5. The main frame is provided at a po ntivi-ntermediate of the ends of the.

side beam, 3 and intermediate beam -l with front vetical column 5, see Fig. 2 and at the rear. ends of said beams 3 and 4 with rear vertical columns 6. Figs. 1 to 4. The front and rear columns, which are secured at their lover ends to the upper flanges of the longitudinal beams 23 and 4. support spaced longitudinal beams 7, which are secured to the upper ends of the columns 5 and 6. The

main frame is stiffened by an inclined trans verse brace '8, see Figs. i and 4, secured at its lower end to the side longitudinal brain 2 and extending upwardly and inwardly therefrom t5; the upper longitudinal beam of the adjacent side of the frame and suitably secured to the same. The main frame is also stiffened by upper and lower inclined longitudinal braces 9 and 10, Fig. 1, arranged in substantiall the same inclined plane. The lower incllned 'brace 9 extends upwardly and rearwardly from the central portion off qsuch front column to the underside of'the adjacent top longitudinal beam 4 and is secured to the adjacent front col- 'umn 5 at a point intermediate of the ends thereof, and the upper brace 10 extends upwardly and -rearwardly from the central portion of such front columnto the underside of the adjacent top longitudinal beam 7, and its upper end is secured to the same near the center of the said beam 7. The top bundles, placing the bands around the same ward and from each other.

In the aocom anying drawings, Figs. 4 and5, two late y adjustable sets of upper and lower auxilia frames or supports are shown for tying {bundle at spaced points at opposite s des of the center, and these auxiliary frames are adjustable by means of upper and lower right and left hand threaded screws 12 and 13, which, when operated by the means hereinafter described, move the sets of frames as units simultaneously to- The machine may be equipped with any number of sets of upper and lower auxiliary frames. When three sets of such frames are employed, one

' set may be located-at the center of the machine and there held stationary, while the fade sets of auxiliary frames or supports will 40 'set' 5 auxiliary frames or supports.

ad'ustable toward and from the centlrkal n alternative arrangement would be to have one end set stationary, and the other two sets relatively adjustable.)

The lower auxiliary frame of each set is rovided at the bottom with spaced longituinal channel bars 14 and'15, see 3 to 9, and at the to with a longitudinal channel bar 15", locate above-and in' substantially the vertical plane of the lower channel bar '14 andconnected with the same at the ends of the lower auxiliary frame by front and rear upright bars 16 and with the ends of the other lower channel bar 15 by inclined transverse braces 17. The lower channel bars 14 and 15 are connected by transverse rods 18, arranged in pairs and secured to the channel bars at the inner faces thereof by screws 19, piercing the webs of the channel bars 14. and. 15 and engaging threaded sockat; in the ends of the transverse rods 18, but any'other suitable means may, of course, be ,em loyed for connectin the channel bars an for maintaining t e same in spa ed- O5 relation.

' gaged by, adjustab The longitudinal bars 14 and 15 of the lower auxiliary frame are slidably connected at their front and rear portions with. the bottom transverse beams l of the main frame by inner stops hereafter described and outer clamps 20, see Figs. 3 and 8, bolted to the bars 14 and 15 at the lower edges thereof and extending across the space between the same. Each clamp is provided 'with an upper recess 21 to receive the outer upper flange of the contiguous transverse beam 1 and is equipped with an adjustable steelplate 22, which is forced into engagement With the lower face of said flange by a set screw 23, mounted in a threaded opening 24 in the recessed projecting portion of the clamp 20. The front inner stop 25, which is spaced from and cooperates with the front clamp, consists of a strip secured to the front portions of the channel bars 14 and 15 and extending across the space between the same, and the rear inner stops are preferably formed by spaced transversely alined hearing blocks 26, secured to the bottom flanges of the bars 14 and 15 at the rear portions thereof. When it is desired to adjust the lower auxiliary frame, the clamps are loosened and after the proper adjustment is effected the set screws are tightened to clamp the frame in position. l

Each upper adjustable auxiliary frame 0 support is preferably composed of spaced longitudinally disposed angle bars 27, Figs. 1 to 5, connected at their rear portions by transverse plates or bars 28, which are '100 The sleeves 32 are supported upon the horizontal flanges of the side angle bars 27 and are interposed between the same and the lower angle bars of the superimposed guide ways, which extend longitudinally of the upper auxiliary frame/ The side bars are also connected at their front ends by a transverse plate or bar 33 (see Fig. 5) having a central vertical n "dle bar guide 34, the 0 plate 33 being bobb d to the yertical flanges of the side bars 27. v

The upper auxiliary frame is slidably supported by the upper transverse main frame beams 11, fitting against the inner 5 edge of the plate ori bar and against one of the transverse. lites or bars 28 and ene lamps35. The clamps in, which are. adjustably secured to t lower faces of thc;'bo ttom flanges'of the side bars 27 of the upper auxiliary frame by screws 36, have recessed engaging portions. which extend beneath the adjacent upper flanges of the transverse beams 11 of the main frame. lVhen the sdrews 36 are tightened to engage the jaws with the upper transverse beams 11.. the upper auxiliarv frame is firmly gripped thereon.

he machine is equipped at the front with a vertical magazine 37.-adapted to receive a stack 38 of material. which may consist of pieces of lumben'or any other material to be handled in bulk and tied in bundles. The magazine. which may be constructed in.an v desired manner. is illustrated in the drawings as consisting ofouter fixed vertical bars 39 and inner adjustable .vertical bars 40.. adapted to, be moved toward and from the'outer fixed vertical bars to varv the size of the ma azine. Each set of upper and] lower auxiliary frames is equipped wit'ha pair of these magazine forming bars 39 and ll), The bar 35) is secured at its lower end to thefront end of the upper channel bar 15* of the lower auxiliary frame, andthc inneri lu ijustable bar 40. which is arranged'iu the same longit-udinal .plane as the outer bar 39. is provided'at its end with a rearwardly extending horizontal arm 41. which is adjustably secured by bolts 42. or other suitable fastening devices. to one of the angle bars 27 of the upper auxiliary frame (see Fig. 5).

As shown in Figs. 1 to 3 inclusive. the inner vertical magazine bars 40 are adpistcd to PIOVldB a bundle of the maximum width.

niit the lower portion of the stack '38 to be advanceduor moved rearwardly from the magazine into a bundle receiving space or chamber 44. The upper longitudinal channel bars 15" of the lower auxiliary frames are spaceda part transversely and constitute a support for the material or bundle; and

the bundle, islmoved'along' the channel bars 15 to the position illustrated in Fig. 3 where it held during the binding thereof.-

The bundle forming or moving mecha{ nism. which feeds the material fromthe bottom of the stack. comprises lower longitudinally.slidable horizontal bars 45; inner vertical bundle engaging bars 46, top horizontal stack supporting bars 47, and outer vertical bars 48 extending upwardly from .the outer ends of. the slidable bars 45 to the outer ends of the stack supporting'bars47. The lower horizontal bar .45, which constitutes a slide, operates the groove or channel of the channel bar 15",whih forms a guide for the said bar 45 and therefore guides the bundle moving means. The vertical bars 46 and 48 are suitably secured at their upper ends to the stack supporting bar 47, and their lower portions are adjustably connected to the slida ble bar 45 by clamping plates 49, secured. by bolts 50, or other suitable fastening devices to the/bar 45 and adapted to clamp the bars 46 and 48 in vertical ad: justment. By'this construction, the effective length of'the bundle forming bar 46 is Y varied to form a bundle of the desired height. and the stack suplmrting bar 47 is raised and lowered to arrange it in proper position for supporting the stack left within' the magazine during the feeding of the material. 1

The inner orrear end of the slidable bottom bar of the feeding device is pivoted to the upperfeud of an inclined connecting link 51; Figs. '1. tot. 8 and 9, extendin lownwjardly and rearwardly from the sli able bar 45 and pivoted at its lower end to the upper end of'a cam actuated lever 52. The cam actuated lever 52is of angular form and when the feeding'device is in its initial position. illustrated in .Figs. 1 and 3, the upper portion of the lever 52 is arranged at an inclination and extends downwardly and rearwardly I over a main transverse shaft 53 to a point in rear. of the same and when the lever is in suchposition its lower portion. \\'lll('ll arranged at an obtuse angle to its upper portiom'extends downwardly and forwardly to a transverse pivot 5+ upon which the lever 52 is mounted.
