Patented Mar. 19, 1918.

Application filed December 21, 1916. Serial No. 188,228.

To all whom. it may concern:

lie it known that I, JAMES M. Lnavnn, 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-Machine, of which thcfollowing is a specification.

The invention relates to an automatic bundling machine.

The object. of the present intention is to improve the construction of bundling machines, and to provide an efficient and c0mparatively inexpensive machine, designed for bundling cut lumber and various other materials, and capable of automatic operation to form bundles of uniform size. A further object of the invention is to provide a bundling machine, equipped with mechanism adapted to engage automatically a predetermined number of ieces of material in a magazine and capable of removing them from the bottom of a stack or pile and of presenting them in bundle form at a point beyond the magazine for binding or tying. Another object of the invention is to provide means for supporting the stack or pile in an elevated position during the feeding operation and the return movement of the feeding mechanism, and for lowering the stack to the bottom of the magazine for recharging the machine after the feeding mechanism has returned to its initial position. The invention also has for its object to provide mechanism of this character capable of ready adjustment to vary the size of the bundle and to arrange the parts to suit the length of the material bundled.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto ap ended.

Fig. 11 is a sectional view on the line 11-11 of Fig. 4, looking in the direction of the arrow.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

, The drawings disclose one embodiment of the invention, while the claims definethe actual scope thereof.

The accompanying drawings, which illustrate the preferred embodiment of the invention, show an automatic bundling ma chine designed primarily for use in Connection with the automatic binding and tying mechanism, forming the subject-matter of a companion application, but the bundling machine of the present invention is also susceptible of operation in connection with any other preferred form of bundle binding and tying mechanism, and if desired the bundles formed by the machine may be bound and tied by hand.

The main frame of the machine, which may be constructed of any suitable material, is provided at the base with front and rear transversely disposed I-beams 1, which may be either mounted on blocks'or sills, or equipped with. heavy casters to render the machine portable. The front and rear trans verse beams are connected at their ends by side longitudinal beams 2 and 3 at a point between their ends with an intermediate longitudinal beam 4. The side and intermediate longitudinal beams, which preferably consist of I-beams, are seated upon the upper flanges of the bottom transverse beams 1 and are bolted or otherwise secured to the same. The main frame is rovided at a paint intermediate of the en of the side m 8 and the intermediate beam 4 with front vertical columns and at the rear,

5 ends of the said beams 3 and 4 with rear vertical columns 6. The front and rear columns, which are bolted or otherwise secured at their lower ends to) the up er flanges of the longitudinal beams 3 an 4,

support spaced longitudinal beams 7, which are cited or otherwise secured to the upper ends of the

columns

5 and 6. The main frame is stiffened by an inclined transverse brace 8, secured at its lower end to the side lo 'tudinal beam2 and extending upwardly an inwardly therefrom to the up er lon tudinal beam of the ad'acent si e of t e frame and suitably secure at its upper end to the same. The main frame is also stifiened 80 by upper and lower inclined longitudinal braces 9 and 10, arranged in substantially the same inclined plane. The lower inclined brace 9 extends upwardly and rearwardly from the front end of the intermediate longitudinal beam 4, and is secured to the adj acent front column 5 at a oint intermediate of the ends thereof, and the up er brace 10 extends upwardly and rearwar y from the central rtion of such front column to the 80 undersi e of the 'top longitudinal beam 7, and its upper end is secured to the same near the center thereof. The top longitudinal beams 7 are connected at points intermediate of their ends by top transversely disposed I-beams 11 bolted or otherwise secured to the longitudinal beam 7- and loca at the front ends thereof and at a point ad jlacent to the rear ends of the same.

he main frame may, of course, be of any 40 other preferred construction, and the bottom transverse beams 1 and the top transverse beams 11 constitute rails and form transverse tracks for slidably mounting a plurality of laterally adjustable upper and lower auxiliary frames or en ports, which carry the mechanism for fee ingthe bundles. In the accompanying drawin two laterally adjustable sets of upper an lower auxiliary frames or supports are shown arso ranged at spaced points at opposite sides of the center of the machine, 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 adjustable frames simultaneously toward and from each other. The machine may be equl ped with any number of sets of 11 per and ower auxiliary frames, but when t ree sets of such frames are employed, one set will be located at the center of the machine and the central set will be stationary and the side sets will be adjustable toward and from the central set of the auxiliary frames or 05 supports The lower auxiliary frame of each set is provided at the bottom with spaced lon 'tudinal channeled bars 14 and 15 and at t e top with a longitudinal channeled bar 15, located above and in substantially the vertical plane of the lower chan- 10 neled bar 14 and connected with the same at the ends of the lower auxiliary frame by front and rear upright bars 16 and with the ends of the lower channeled bar 15 by inclined transverse braces 17. The lower channeled bars 14 and 15 are connected by transverse rods 18 arranged in airs and secured to the channeled bars at the inner faces thereof by screws 19, iercing the webs of the channeled bars 12 and 15 and engaging threaded sockets in the ends of the transverse rods 18, but any other suitable means may, of course be employed for connecting the channeled bars and for maintaining the same in spaced relation. 35

The longitudinal bars 14 and 15 of the a lower auxiliary frames are slidably connected at their front and rear portions with the bottom transverse beams 1 of the main frame by inner stops and outer clam s 20, 9o bolted to the bars 14 and 15 at the lower edges thereof and extendingacross the space between the same, and eac provided with an u per recess 21 to receive the outer uper ange of the contiguous transverse beam and extending beneath the said upper flange and equipped with an adjustable steel plate 22, which is forced into. engagement with the lower face of the outer upper flange of the transverse beam by a set screw 23, mounted in a threaded opening 24 in the recessed portion of the clamp 20. The front stop 25, which is spaced from and coiiperates with the front clamp, consists of a strip secured to the front portions of the channeled bars 14 and 15 and extending across the space between the same, and the rear stops are preferably formed by spaced transversely alined bearing blocks 26, se-. cured to the bottom flanges of the bars 14 and 15 at the rear ortions thereof. When it is desired to ad net the lower auxiliary frame, the plates 0 the clamps are loosened by unscrewing the set screws and after the proper adjustment has been made, the set screws are ti htened to cause the steel lates to grip firmfy the bottom transverse came of the main rams.

Each upper adjustable auxiliary frame or support is 1preferably composed of spaced longitudina y disposed angle bars 27, connected at their rear portions by transverse plates or bars 28, which are secured to the orlzontal wings or flanges of the angle bars 27 by vertical rods or bo ts 29, piercin hori- 126 zontal wings pr flanges of spaced angfc bars' 30, arran in pairs at opposite sides of the rear ortipn of theupper auxiliary frame and rming horizontal guideways. The horizontal wings or flanges of the angle bars 30 of the guideways are spaced apart by sleeves 31, and the lower angle bars of the guideways are sup orted by vertical tubes 32. The sleeves and the tubes are arranged on the vertical rods or bolts 29, and the tubes are supported upon the horizontal flanges of the side angle bars 27 of the upper auxiliary frame and are inter osed between the same and the lower ang e bars of the superim osed guideway, which extends longitudinal y of the said upper auxiliary frame. The side bars of the upper auxilia frame are also connected at their front en s by a transverse plate or bar 33, having terminal flanges oo ted or otherwise secured to the vertical wings or flanges of the side bars 27.

The u per auxiliary frame is slidably supported by the upper transverse main frame beams 11, fitting against the inner edge of the plate or bar 33 and against one of the transverse plates or bars 28 and engaged by adjustable clamps 35. The clamps 35, which are adjust ably secured to the lower faces of the bottom flanges of the side bars 27 of the upper auxiliary frame by set screws 36, have recessed engaging portions, which extend beneath the adjacent upper flanges of the transverse beams 11 of the main frame. When the screws 36 are tightened to engage the jaws of the upper transverse beams 11, the upper auxiliary frame is firmly gripped thereon.

The 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 cut lumber, or any other material of a similar character, adapted to be handled in bulk and tied in bundles. The magazine, which may be constructed in any desired manner, is illustrated in the accompanying drawings as consisting of outer xed vertical 'bars 39 and inner adjustable vertical bars 40, adapted to be moved to ward and from the outer fixed vertical bars to vary the size of the magazine. Each set of upper and lower auxiliary frames is equipped with a pair of these ma

zine forming bars

39 and 40 and the upper on tudinal channeled bars of the lower aux] iary frames constitute the bottom of the magazine. The fixed outer vertical bar 39 is secured at its lower end to the front end of the upper channeled bar 15 of the lower auxiliary frame, and the inner adjustable bar 40, which is arranged in the same longitudinal plane as the outer fixed 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 1n Figs. 1 to 3 inclusive, the inner vertical magazine bars 40 are arranged at the limit of their rearward movement to provide a bundle of the maximum width, and they are adapted to be adjusted for-- wardly from such position to decrease the width of the bundle. The inner ad ustable magazine forming bars 40 terminate at the side bars of the upper auxiliary frames to form an opening 43 at the lower portion of the inner or rear side of the magazine 37 to ermit the lower portion of the stack 38 to be advanced or'moved rearwardly from the magazine into a bundle receiving s ace or chamber 44. The upper longitu inal channeled bars 15" of the lower auxiliary frames constitute a su port for the material, and the bundle when ormed by the feeding mechanism about to be described is movable alon the channeled bars 15 to a int beyour the magazine to the position i1 ustrated in Fig. 3 of the drawin The feeding or bun le forming mechanism, which feeds the material from the bottom of the stack, comprises in its construction a lower longitudinally slidable horizontal bar 45, an inner vertical bundle engaging bar 4.6, a top horizontal stack supporting bar 47, and an outer vertical bar 48 extending u wardly from the outer end of the slidab e bar 45 to the outer end of the top stack supporting bar 47. The lower horizontal bar 45, which constitutes the slide. operates in the groove or channel of the top longitudinal bar 15, which forms a guide for the said bar 45. and 48 are suitably secured at their upper ends to the horizontal stack supporting bar 47, and their lower portions are adjustably connected to the slidable 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 adjustment. By this construction the effective length of the bundle forming bar 40 is varied to form a bundle of the desired height, and the stack supporting bar 47 is raised and lowered to arrange it in the proper position for supporting the stack left within the magazine during the feeding of the material in the formation of the bundle.

The inner or rear end of the slidable bar of the feeding device is pivoted to the upper end of an inclined connecting link 51. extending downwardly and rearwardly from the slidable bar 45 and pivoted at its lower end to the upper end of a cam actuated lever 52. The cam actuated lever 52 is of angular form. and when the feeding device is in its initial position, or at the limit of its outward or forward movement, as illustrated in Figs. 1 and 3 of the accompanying drawings, the upper portion of the lever 52 is arranged at an inclination and extends downwardly and rearwardly over a main transverse shaft 53 to a point in rear of the same, and when the lever is in such position, its lower portion, which is arranged at an ob- T he vertical bars 46 tuse angle to its upper portion, extends The vertically movable stack supporting I downwardly and forwardly to a transverse and charging devices are connected by links pivot 54 upon which the lever 52 is mounted. 64 with oscillatory arms 65 of a front trans- The pivot 54 is arranged in a suitable bearverse shaft 66, provided with a longitudinal 5 ing bracket 55, secured to the channeled bar groove or keyway 67 to receive keys for 14 at the lower web or flange thereof.

89 and 90 are mounted on the outer ends of the screws, which have reduced threaded inner terminals 91 receiving nuts 92 and washers 93 interposed between the adjacent bearings and the nuts, which are adjustable to take up any end motion of the right and left hand threaded screws. The upper and lower sprocket wheels, which receive the end thrust at the outer ends of the upper and lower adjusting screws, mesh with and are connected by a sprocket chain 94, which also meshes with a sprocket wheel 95 fixed to a rotary shaft 96, mounted in a bearing opening in the outer front column of the main frame of the machine and provided at its inner end with a collar 97, keyed or otherwise secured to the inner end of the shaft 96.. The sprocket wheel of the front lower right and left hand threaded screw is located at a point in advance of the up er front sprocket wheel, and the sproc et chain, which extends downwardly from the upper front sprocket wheel, passes beneath the sprocket wheel or pinion 95 and extends downwardly and forwardly at an inclination to the lower front sprocket wheel. The sprocket wheel 95 is arranged at a point intermediate of the shaft 96 and is located at the outer face of the said column. The shaft 96 is provided at its outer end with a suitable operating device preferably consisting of a crank handle 98, adjustably secured in a transverse opening in the said shaft by a set screw 99. The sprocket gear is adapted to rotate simultaneously the right and left hand threaded screws, which move the upper and lower auxiliary frames laterally o the machine to space them and the mechanism carried by the frames the desired distance apart to suit the length of the material to be bundled.

The cam wheel 58 is provided with an extended hub or sleeve 163, having a key 164 to engage a longitudinal groove or guideway in the main transverse shaft 53 to slidably interlock the cam wheel 58 with the same. The cam wheel 58 of the lower auxiliary frames is adapted to slide along the main transverse shaft when the auxiliary frame are adjusted laterally by the right and left hand threaded screws.

The machine may be driven by any suitable power, which is connected by a belt with a pulley 267 loosely mounted on a transverse driving shaft 268, journaled in suitable bearin 269 of the main frame and carrying a pinion 270 which meshes with a gear wheel 148. The bearings 269 are preferabl mounted on the longitudinal beams 2 an 4 of the main frame, and the pulley 267 is connected with the drivin shaft by a clutch 271, which may be 0 any preferred construction. The clutch 271 is connected with a handle or lever 272, fixed to a longitudinal shaft 273, from which de' pends an arm 274 having a projecting point 275, which is carried into the path of a lug 276 of the gear 148 when the pulley is clutched to the driving shaft.
