BASKET-MAKING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 722,962, dated March 17, 1903. Application filed September 17 19 02. Serial No. 123,725. (No modeL) To all whom it may concern:

Be it known that I, CARL ENGBERG, a citizen of the United States, and a resident of St. Joseph, in the county of Berrien and State of Michigan, have invented new and useful Improvements in Basket-Making Machines, of which the following is a full, clear, and exact description.

This invention relates to. a machine for stapling hoops on baskets, and is especially.

intended for putting into place the bottom hoops of bushel-baskets, which baskets have rounding bottoms, the hoops serving not only to strengthen the baskets, but also to form a. flat bottom surface, allowing the basket to stand upright. 7

The machine in its general Iformembodies two work-holding devices, including means for feeding the hoops with a step-by-step motion, and a single stapling mechanism, which is mounted to work alternately over the workholding device, so that one basket may be operated on while another is being adjusted into position on the other work-holder.

This specification is a specific description of one form of my invention .while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indi-- cate corresponding parts in all the figures.

Figure 1 is a; side elevation of the machine. Fig. 2 is a side elevation with parts broken away. Fig. 3 is a plan view. Fig. 1 is a vertical section. Fig. 5 is a detail section of the feed-basket wheel. Fig. 6 is a detail section of the anvil-pin, and Fig. 7is a detail view of the adjusting or gage bar.

10 indicates the table or base of the machine, which is suitably supported on legs 11 and which has a rigid upwardly projecting bottom portion 12, forming a box in which turns the tubular shank 14 of the arm 15 of the stapling mechanism. This arm projects forwardly and is arranged to turn with the tubular shank 14 to a position either to the right or left of that shown in Fig. 3, said view illustrating the arm in its intermediate orinactive position.

16 indicates the shaft which operates the stapling-head 17, this shaft being vertically movable in the'tubulaushank 11 and connected at its lower end by a link l7 with a strap of an eccentric 18. Said eccentric 18 hasan axially elongated hub 19, mounted loosely on the drive-shaft 20 and carried in a box 21 beneath the table 10. The hub 19 carries at its outer end a'cam 22, the purpose of which will be hereinafter described.

23 indicates a band-wheel on the shaft 20. 6o

Formed on or fastened to the eccentric 18 is a clutch member 24, wherewith coacts a member'25, fastened on a sleeve 26, which sleeve is splined on the shaft 20 and is connected with the forked end 27 of a lever 28. This lever has its lower end fnlcrumed on a stud-shaft29, carried in the framing below the box 21, and the upper end of said lever is connected by a link 30 with an arm 31, carried on a collar 32, fastened securely to the lower end of the tubular shank 14E.

7 33 indicates a retractile spring connected with the arm 31 and fastened to the front of the table 10, beneath the same. The arm 31 lies in vertical plane with the arm 15, and the spring 33, connected as described, tends to hold said arm 15 in the intermediate position illustrated. In this position the clutch member 25 is disengaged from the member 24 and the shaft 20 rotates idly in its bearings. When, however, the arm 31. is thrown to either side, the upper end of the lever 28 is thrown rearward and the clutch members 25 and 24 are engaged, thus turning the elements 18 and 22 with the shaft 20. The consequent rotation of the eccentric 18 imparts a verticalreciprocating movement to the parts 16 and 17, and thus operates the stapling mechanism. This mechanism may be of any desired form and does not in itself constitute 0 a part of the present invention.

Pedestals 34: are mounted on the table at each side thereof, and each pedestal carries revolubly a work-holder 35, said work-holders being adapted to have the baskets placed 5 thereon in inverted positions, as shown by dotted lines in Fig. 2.

At each side of the machine and at the rear thereof are mounted two pairs of standards 36. In each pair of standards is mounted a I o fulcrum 37 of an elbow-lever 38. The long arms of these levers project forwardly to a of its operating positions.

point directly over the respective work-holders, and the short arms incline downward and rearward and are formed with slots 39 therein. In the slots 39 pins 40 play loosely, and these pins are carried on arms 41, said arms being mounted fast on the respective shafts 42, carried in the beforementioned standards 36. To the shafts 42 are respectively fastened elbow-levers 43, the long arms of which project forward at each side of the machine and are provided with handles 44, facilitating the manual operation of the levers, while the short arms of said elbow-levers 43 have retractile springs 45 connected thereto, which springs serve to hold the levers yieldingly in either one of their two positions. The front ends of the levers 38 each carry a vertically-disposed box 46, and in these boxes are mounted to turn vertical shafts 47, (see Fig. 5,) each shaft 47 carrying on its lower end a hoop-feeding ratcheted or notched wheel 48 and on its upper end a ratcheted Wheel 49. The wheel 48 has slight spurs 48 on its under side to engage and turn the basket, as will be fully described hereinafter. Each shaft 47 has an upward and laterally-turned extension 50, which turns with the shaft, and these lateral extensions 50 are adapted to engage the hooked ends 51 of levers 52. Said levers are fulcrumed at each side of the arm 15 on a transverse shaft 53, the levers being fastened to this shaft and one lever extending rearward to a point back of the arm 15, where it is connected with a vertically-movable lock-bar 54. Said lockbar is mounted to move in an arm 55, projecting rearward'from the arm 15, as best shown in Fig. 3, and 56 designates a spring pressing down the rear end of the lever. When the stapling mechanism swings to either one of its operative positions, the extension 50 of the shaft 47, toward which the stapling mechanism is moved, will strike at the end of the stapling operation the hooked end 51 of the adjacent lever 52 and throw said lever down into position shown by full lines in Fig. 2, whereupon the stop-bar 54 will be raised. This bar extends down to a rearwardly-disposed bracket 57. Said bracket is formed, as best shown in Fig. 3, with two openings 58 therein, and in these openings the stop-bar'54 is adapted to enter, whereby to hold the stapling mechanism in either one When the stapling mechanism is thrown to one side, the spring 56 automatically throws the stop-bar 54 into one of the openings 58, and this holds the stapling mechanism against further swinging movement. The extensions 50 of the shafts 47 are so adjusted that at the end of the stapling operation said extensions will ride over the ends 51 of the levers 52. This withdraws the pin 54, and the spring 33 then acts to throw the stapling mechanism in its intermediate or inactive position.

59 indicates a handle which is attached to the arm 15 to facilitate throwing said arm from inactive to active position. As pointed out above, the arm is automatically thrown from active to inactive position.

Attached to the bearings 46 by means of arms 60 are the tubular guides 61 for the hoops. These hoops are indicated by the letter a. in the drawings. The guides 61 are disposed tangentially to the toothed feedwheels 48, so that the hoops are fed to the periphery of these wheels, and the rotary movements of said wheels cause the hoops to be drawn over the basket.

62 indicates standards which are mounted on the table 10 alongside of the work-holders 35, and these standards carry anvil-pins 63, against which the stapling mechanism Works. (See Fig. 6.) The anvil-pins 63 have a concave top 63. The pins 63 are sustained on the standards 62 by springs 62", and 62 indicates pins which are carriedrigidly on the standards and fit loosely in the longitudinally-orificed anvil-pins. The movement of the pins 63 is limited by a screw 63", which plays in a groove 63. The basket is held up against the under side of the hoop-feed wheels 48 by means of springs 64, which are attached to the said standards 62 through the medium of the screws 63*. In the stapling operation the staple is first struck on the concave end 63 of the pin 63, and as this yields it turns the points of the staple inward, and finally these points strike the top of the pins 62,-and the clenching operation is thus completed.

In Figs. 1 and 3, 65 indicates the devices for feeding the wire of which the staples are formed, and this device is operated, as best shown by the dotted lines in Fig. 4, by a pawl 66, connected with one arm of an elbow-lever 67. Said lever is fulcrumed at the point 68 and is operated by a link 69, attached to the vertically-reciprocating arm 17. The rocking of the lever 67 drives the pawl 66 reciprocally.

The shafts bearing the hoop-feed wheels 48 are driven by pawls 70, which work with the ratchet-wheels 49, said pawls having guides 71 loosely engaging the top and bottom faces of the ratchet-wheels, whereby to hold, the pawls in operative position and prevent them from falling out of. engagement with the ratchet-wheels 49. ward and are attached to links 72, which in turn are connected by pins 73 with the arms 74 of a forked lever 75. crumed at the point 76. (See Figs. 1 and 4.) The pins 73 are loosely engaged by the links 72, and 74 indicates springs which are coiled around the pins and press the links yieldingly against the arms 74. This allows the pawls 71 a slight lateral movement and normally holds said pawls disengaged from their ratchets. (See Fig. 3.) Fastened to each side of the arm 15 is a spring-arm 77, these arms carrying at their free ends rollers or the like 78, which rollers are opposite the respective pawls 70, and when the stapling Said pawls extend rear- Said lever is fulmechanism is thrown to one side or the other the roller strikes the adjacent pawl and throws it laterally into engagement with its ratchet-wheel. With respect to these parts it will be observed that by throwing down the levers 43 the arms 38 may be raised into vertical or approximately vertical positions, these arms carrying with them the guides 61 and wheels 48 and 49. The pawls also move upward, turning around the centers of the pins 73. The purpose of this is to uncover the work-holders 35 and enable the basket to be placed thereon, the springs holding the levers 38 either raised or lowered. The lever engages its lower end with the cam 22, and by means of this cam the lever is rocked, which rocking movement of the lever drives the pawls 70. These pawls are not however active with the wheels 49 until they are pressed sidewise by the spring-arms 77, as above explained.

79 indicates arc shaped adjustingbars, which are carried on longitudinal reciprocal arms 80. Said arms extend forward and backward and are mounted suitably in the standards 36. The rear end of each arm is turned upward, as indicated at 81, and these upturned ends are engaged, respectively, with the ends of the arms 41. The arms 80 have upward extensions 82, (see Fig. 7,) which bear against the forward side of the slotted arms 39 of the levers 38, and thereby throw the arms 80 forward into active position when the levers 43 are thrown down, thus holding the adj usting-bars 79 forward to engage the basket and position it properly on the work-holder. When the arms 43 are thrown up to return the levers 38 to their lowered position, the ends of the arms 41 bearing against the upturned ends 81 of the arms 80 withdraw the arms 80 and move the adjusting-bars 79 rearward out of engagement with the basket.

In the use of the invention the hoops are placed in the guides 61, and the basket is adjusted on the work-holders 35, the levers 38 having been raised previously to placing the basket in position. The raising of the levers 38 results in the movement of the adjustingbars 79 forward into active position in the manner before described. The baskets having been placed on the work-holders against the adjusting-bars, which gage the position of the baskets, the levers 38 should then be thrown down into operating position, the adjusting-bars 79 moving out of the way, so as not to interfere with the turning of the hasket on the work-holder. The spurs 48 engage the basket and cause it to turn as the disk 48 turns. After this has been done the stapling mechanism is thrown toward the side on which is located the basket to be first operated upon. Assuming that the stapling mechanism be thrown to the right in Fig. 3, this movement will result immediately in driving the eccentric 18 and cam 22. The right-hand pawl will be engaged with its ratchet-wheel, and the elements 49 and 48 at the right-hand side will be driven with a stepby-step motion, imparting a like movement to the basket. Simultaneously the arm 17 is reciprocated, and the stapling operation is thereupon carried on. When the first staple is driven, the hoop is thereby attached to the basket, and as the basket turns the hoop is drawn through the guide 61. During this movement the hoop is caused to run around the periphery of the disk 48, which thereby gages the position of the hoop on the basket. The notches in the periphery of this disk are provided to allow the stapling mechanism to work through the notches. This operation continues until the basket has been turned once on the work-holder, and the hoop will thereby be placed in a circle around the basket. At this period the lateral extension 50 of the shaft 47 strikes the right-hand lever 52 and throws upward the stop-bar 54, and the spring 33 then moves the parts into the position shown in Fig. 3. The operator then throws the stapling mechanism toward the left, and the operation is repeated, as above described. During this second operation the right-hand lever 43 should be thrown down and the right-hand lever 38 thereby raised, so that a third basket may be placed on the right-hand work-holder in readiness for a repetition of the operation.
