7 Claims. (01. 19s-21j This invention relates to an automatic feeding device and is directed more particularly to cigar feeding means adapted for use in connection with 5, av cigar banding-machine to feed cigars to said machine for banding application. v

Au'tomaticIfeeding devices have been heretofore proposedfor feeding cigars to the banding machine. However, such devices as. far as I am 10 chine, or in other words, both the foiling machine and the feeding device for the banding machine The are operatedbya common prime mover. feeding device has also been connectedor synchronized with means for'moving' a body of cigars to-' wards said device; The objection to having the cigar feeding device for the banding machine operated or controlled for operation directly with thelfoiling machineor the means for moving the my body of cigars is that said feeding device will op- "erate regardless of theposition of the cigars and thatparticular care mustbe taken to synchronize The primary object of the present invention is to overcome these objections and to provide a feeding device which is controlled entirely by the cigars moved towards the feeding device of the banding machine, thereby insuring the correct positioning of the cigar before injecting the same by. the feeding plunger into and underthebanding Another object of the invention resides in the provision 'ofa feeding device and abanding machine which are synchronized in motion with each other and rely upon the flow of the cigars tov 45 "regulate the successive delivery of said cigars to the banding! machine. 7

It is also an object to combine the feeding device of the banding machine with a cigar foiling v v,machine, wherein the cigars after being foiled are moved in a body side by side and horizontally over a table by the ejecting mechanism of the foiling machine. This arrangement is particularly desirable in that the'b'ody of the cigars thus forms g and thecigars may thus'be discharged from the aware, have been synchronized with a foiling ma-- ,aconnecting elementbetween the two machines foiling machine at regular intervals or intermittently and fed to the feeding device of the banding machine in the same manner eliminatingthe necessity of having the feeding device of the banding machine in operation during the idling:

operation of the foiling machine.

'A further object of the invention is 'tocontrol the banding machine and the associated flcigar feeding device therefor electrically by inserting a switch in the path of the moving body of cigars with which the cigar nearest the feeding device engages to close a 'circuit, whereby through the provision of an electromagneticdevice, the feeding device will be operated, but by the absenc of by spring action to an open circuit position.

It is also an objectof the present invention to:

provide an automatic feeding device of this character which will obviate the necessity of an opera: tor for feeding the cigars to thebanding macl'iine'.

a cigar adjacent the switch the latter will move;

I With these'and otherobjects in view,which appear as the description proceeds, the invention? consists in the novel features. ofvpconstruction,

combination of elements and arrangemen t ofij parts hereinafter to be more fullyfldescribed an'd pointed out in the appended claims.

Referring more particularly to the drawings the numeral l designates generally the banding machine; the numeral 2 the cigar carrying table and the numeral 3 the cigar foiling "machine whichin this instance forms the meansfor feedf ing or moving the cigars overr'the table-2. A

The foiling machine, which is of common construction, includes a rotatable carrier 4 having spaced movable finger elements 5 mounted there- 'on between which the cigars 6 are held and acted 5 upon by mechanisms (not shown) for applying the foils or wrappers to said'cigars, the mecha- ,nism of the carrier 4 and the fingers 5 being such as to discharge or release the cigars at the end of thetable nearest the carrier 4 andat which 10 point other mechanism including a reciprocatory,

From the structure sofar described, it'will be noticedthat 1thebanding machine and the feeding device therefor is directly connected for. simultaneous operation or 'driven from the same 20 motor.

The banding machine and the feeding device are thus continuously operated during the flow of the cigars towards the finger '38. However, upon an interruption in the'fiow of cigars the finger 38 will be free to moveto a position separating the contact points. 44.and.45 andbreaking the circuit, thus stopping the operation of the banding machine and. the feeding plunger II. The arrangement of the clutch mechanism is. such that the machine completes the cycle and causes the plunger to cometo rest at its retracted position free from engagement with the cigars. It will be noted'by referenceto Figures 6 and 7 that the plunger II is positioned or elevated above the cigars, thus permitting the incoming cigars to move into engagement with the finger 38' without interfering With the plunger upon its rearward or retractedstroke. Thecigar-engaging piece G5 which is hinged at the forward end of the plunger II will, due to its hinged connection with the plunger ll, swing upwardly and slide over the cigar the full length thereof until free from the end of the cigar at which time the piece I5 will drop to a vertical position. This cigar engaging member I5, which is illustrated in Figure 5 to best advantage, has its upper end pivoted or hinged within the slot 54 and. rounded as at 55 permitting of the free outward and upward movement of the member 15 but is prevented from swinging rearwardly and under the plunger due to the fact that the straight face 56 engages the inner end of the slot 54. This will retain the member l5 vertical and at right angles to the plunger I l during the feeding of the cigars under the banding head. This arrangement is thought novel in that it permits the cigars to move into engagement with the finger 38 and keeps the circuit closed while the plunger is moving to its retracted position.

It will be noted that the cam 3| only functions to move the plunger element II to its retracted position and the spring 36 serves to move the plunger forward on its cigar injecting stroke. This is highly desirable in that in case the cigar gets out of alignment with the plunger and becomes caught in the guideway or the ejecting mechanism 51 of the banding machine fails to function properly, the damage to the cigar will be less than if the plunger were moved positively in this direction by the cam.

By pivotally mounting the contact carrying finger 46 flexibility is provided between the points 44 and 45 and permits the point 45 to move after being engaged by the other contact point, thus assuring more efficient contact therebetween. The points 44 and 45 which may be formed of any suitable metal are adjustable within their sockets and may be removed therefrom for replacement. To prevent undue sparking or arcing between the ends of the contacts 44 and 45 a condenser is positioned between the leads 48 and '49. This will increase the wearing life of the contact points and assures more effective operation of the switch device. In case the foiling machine is not in operation the row of cigars may be moved by hand longitudinally of the table until all of the cigars have passed through the banding machine by means of the feeding device, before described. In order to keep the banding machine in operain one direction will engage a spring anchoring screw 6! of the finger 38 and cause the spindle" M3 to rotate effecting the closing: ofthe circuit Ezi due totheengagement of the points 44 and.45.: I
