MEANS FOR ATTACHING HINGED LIDS TO RECTANGULAR METAL BOXES.

Application filed October 9, 1922.

To all whom. it may canoe mt:

Be it known that ANDREW FRANCIS Nnr, a subject of the King of Great Britain, residing at Glenelg, Edward Street, East Kew, in the State of Victoria, Commonwealth of Australia, has invented new and useful Improvements in Means for Attaching Hinged Lids to Rectangular Metal Boxes, of which the following is a specification.

This invention refers to rectangular metal boxes with hinged lids such for instance as are used for containing vestas tobacco or chocolate. Such boxes are punched in one side witha pair of aligned'h'inge pops into which are respectively inserted the ends of a hinge pin adapted to be engaged by the curved hinge tail of the lid, which hinge tail is clamped to embrace the pin, said operations except that of forming the hinge pops and bending the hinge tail having hitherto been effected by manual labour.

The primary essential features of the invention consists of mechanical means for auton'latically fitting a hinge pin into the pops of the tin body, feeding the lids to said pins, and bending the tail piece about the same, the pin fitting, and lid feeding and bending operations being effected in sequence by associated means controlled and actuated in tuned relationship.

A further characteristic feature of the invention consists in the association with said primary features of means for feeding from a reel, the wire to form the hinge pins, the straightening and cutting of said wire into hinge pins of uniform length, said operations being followed by the pin fitting and lid attachment operations mentioned and all in conjunction with an intermittent box body feeding means, the whole of the functions being performed in tuned relationship controlled by a single cam shaft.

T he accompanying drawings illustrate an apparatus which will perform in a practical manner, all the essential features hereinbefore mentioned.

Referring now to these drawings Fig. 1 is a plan and Fig. 2 a side elevation of the machine with parts broken.

According to this invention the bodies of the boxes B are caused to travel intermittingly by a chain carrier 1 in a channel guide way 2 past the various mechanically operated parts of the machine. The hinge wire 3 is supplied on a reel 4 and drawn from same through straightening pins 5 by means of grippers 6 (Figs. 1, 2, 24 and 25) one part being mounted on pivoted arm 7 and the cam grip 7, which opens and closes on the wire, is connected with an arm 8 operated by pivoted lever 9 having a roller 10 actuated by cam 11 on the main shaft 16. As shown in Figs. 24 and 25, the wire gripper arm 7 is bifurcated and carries the gripper block 6, beneath which the wire 3- is fed. The cam 7 is operated bythearm 8 and lever 9 to press the block 6 on the a guillotine device the knife13'of which is pivoted at 13 and has at its lower end a roller '14 operated by a cam 15 on shaft 16 so that said knife is reciprocated past thestationary member 12 and shears the wire into the requ'ired'lengths or pins PI The"-wire pin P-is fed through a stationary hollow guide 17 (see Fig. 11) inclined towards the box and the box carrier chain 1,

and engages a guide groove 18 (Fig. '9) in a clamp 19 while its forward end p enters the advanc'ehinge pop 29 of the box (Figs; 3 and g The front end 39 of the pin}? (Fig. 5) enters the'box and is gripped against the side-thereof by means of a gripper 30 having a serrated face (Figs. 6, 7, 8 and 10) said end p-abuttingfagainst a shoulder or abutment 31- on said gripper 30. The latter isprovided'on the end of an arm'36, pivoted on a bracket on a carrier 2 1,'the latter being.

reciprocated on 'the base plate 22 parallel with the boxes by means of levers23y24, 25

(see Fig 2) the latterbeingifixe'd'to a'slide 109 carrying roller26 engaging slotted cam 126 *on shaft 16, said levers 23"and 24; being formed respectively with slots 100, 101. The clamp 19 is mounted'on a verticalpivot pin 20 (Figs 9 and 11) on'the carrier 21- has an offset arni 27 ,'an'd is urgedtowar ds the rear endofthe pin and the boxes by a spring 28 1 on the pivot 20, said-clamp 19 is also provided 'ontop with a pin 32 adapted to contact with a stop 33 (see-Figs. 7, 11 and'12).

Gripper-3O iscontrolled by a spring3 4- (see Fig. 6) and is provided at-the endiwith the arm 36 of the gripper andsupported on a horizontal rail 37' supported on standards 38' vertically slidable in bearing sleeves-39 (Figs, 2 and 6) onthe base plate 22.

These standards are connected together by" a horizontal rod 40 (see Figs; 2 and 21) and this rod'passes through a slot 120 in a pivcted arm 41 controlled-by a spring-42 and carrying'two' rollers 43,-4d engagingre'spem tively canis45' and 16 (Fig. 2) on the shaft 16. Cam 15 operates to slightly lower the rail 37 and release the gripper 30 and cam 26 completes this movement. v

7 -designates a stop for the 29 engagesa guide slot 54L formed in a bar 55- (Figs. 6, '7, 15 and16) on the-carrier to ensure said popbeing in correct position to receive the end of the hinge pin and the box is kept down 'in" 'thel'guide wayibyithe overlying hold down plate 56 (Figs. 1 and 7).

Assuniingthepart's to be in the position shown in Figs. 1 and 2 i. e. with the pin P in the advance hinge'pop 29 and gripped by gripper 30;at the 're'ar end the pin is cut" away from the reel by the guillotine knife 13 andclamp 19 with the rear end of the pin in line with 'the' rearmost hinge pop 52.

Lever'2d operates "to reverse the movement of the carrier 21,bu.t there'is a slight idle stroke on account of theslotlOO (Fig.1 2) in lever 23. hen the carrier starts to move back wards, at which time the box carrier chain is stationary, the shoulder 31" 011 gripper '30" pushes the pin backwards to engage thehinge pop-52 asinFi'gS. 3 and 4 and-then the gripper swings on its pivot and releases its hold thus permitting the box to advance. The backwardmovement of the carrier continues'and finger 48 advances in the path of offset 27 of the clamp'l9 whichswings the clamp away fromthe box till it bears against the frame 53 of the guillotine or other abutment as in Fig. 11. Finger48 then retires as the carrier a gain moves forward and when theclainp freeathe'" frame*-53 its spring swings it sharply inwards as in F ig.; 12 when pinj32 contacts with stop 33 thensliding off saine impinges the rear end of the pin 7) against the box and'in linewith therear most pop 52 Prior to'this latter movement the gripper 30 has moved into position to receive thefrontendof the 'pin against its g of the lid attaching mechanism." The lids'L a concave roller 35 longitudinally slidable onare 'fed down an inclined chute overlying the boxes and the lowermost"lidcomesto rest on afiange'dsupport 58" (see FigzilT) on the side of the-guid'ewayin an angular position overlying"the-box; and with its lower edge belowthe hinge'pin: The cai'- rier 21 is provided'witlra pusher 59 projecting therefrom (Figs. 15, 16) formed with an extended fingerGO which supports the at 62 to receive the curved hinge tail 63 of the lid.

The lid is supported in correct inclined position i. e. leaning towards the box by a flange 7 4 on the elevator (see Fig. 14) and also by means of a reciprocating hook 75, (Figs. 1 and 2.) on an arm 64 controlled by means of lever 65 having an arm 66 provided with a roller 67 engaging cam 68 on shaft 16.

The elevator 61 is spring controlled and pivoted on pivot 69 (Fig. 13) and is reciprocated vertically by means of arm 70 carrying roller 71 engaging cam 72. As the elevator rises the edge 93 of the hinge tail 63 (Figs. 13 and 14) passes upwardly between the hinge pin P and the side of the box after which hook 7 5 draws the lid back past a vertical plane through the hinge so that it falls and swings into full open position and as the box is advanced, curved arm 7 6 iixed 011 the base ensured the lid coming down flat on the edge of the guideway 2. During the operations of connecting the lid to the hinge pin on the box, the latter is prevented from rising by a reciprocating plate 77 on lever 78 operated by arm 79 carrying roller 80 operated by cam 81. .Also while the lid is passing the curved arm 76, the box is held down by a plate 82 fixed on the base.

The box with its lid is now advanced to the mechanism for bending the hinge tail around the hinge pin. and this mechanism is illustrated in detail in Figs. 18 and 19.

This mechanism consists of a presser foot 83 having a ledge 84 at the bottom and formed on a spring controlled lever 85 with its upper portion bent approximately horizontal and its lower or approximately vertical portion provided with a roller 86 in engagement with a cam 87 on the shaft 16. Operating in conjunction with the presser foot is a reciprocating backing block 187 adapted to descend in the box and bear firm- 1y against the side thereof to which the hinge pin is connected. The bilock is mounted on a lever 88 connected with an arm 89 having a roller 90 contacting with cam 91 on shaft 16. Fixed to the block 187 are angle plates 92 that hold the box in the channel guide way 2.

As the box advances to this mechanism the edge 93 of the hinge tail of the lid slides along the ledge 84 and when the block 187 is in the box the lever 85 operates and foot 83 descends and by reason of its shape and position of its pivot at the same time moves towards the box thus bending the edge 93 of the hinge tail to enclose the hinge pin I as in Fig. 20.

The box with its hinged lid is advanced another step and passes under a hold down plate 94 and is subjected here to pressure in the side opposite the hinge to ensure that said side will not be bulging out suliiciently to prevent the lid from closing. This means consists of a spring controlled horizontal slide 95 reciprocating in a guide 96 and operated by a lever 97 and an arm 98 having a roller 99 actuated by a cam 103.

When the box proceeds the lid engages the inclined arm 104 which raises said lid and swings it over on its hinge pin till it drops in closed position on the box.

A spring controlled arm 105 bears on arm 104 and permits the latter to yield if neccssary.

The chain carrier 1 passes over sprockets 106, 107 and as it turns down over the sprocket 107 the boxes with closed lids are deposited on and carried away by a travelling belt 108.

Slide 109 operated by cam 126 on shaft 16 carries a dog 110 (Fig. 2) engaging a ratchet Wheel 111 integral with sprocket wheel 107 thus causing intermittent movement of the carrier chain 1.

Motion is transmitted to shaft 16 by pinions 112 113, the former being fixed on the main drive shaft 114.

From the foregoing it will be appreciated that the steps necessary for the fitting of a hinge pin to a box, the attachment of a lid to said pin the bending of the hinge tail of the lid round saw pin, the closing of the lid and final delivery of the box with closed lid are all performed in regular quence and the operations can be carried on continuously and with a degree of speed and accuracy unattainable by hand labour. The performance by mechanical means of the said sequence of steps has not so far as known previously been effected.
