1 Claim.

This invention relates to cigar piercers, and the present application is a divisional from the earlier application for United States Letters Patent upon Cigar piercer, Serial No. 12,720, filed March 23, 1935, in which is disclosed mechanism for automatically piercing the head end of a cigar with an axial opening so as to render the latter ready for smoking, without first cutting or biting 01f the cigar end.

An important object of the invention herein disclosed is to provide coordinated means for first piercing a cigar and then enveloping it, preferably with a water proof material which will serve to prevent any tendency toward drying out through the perforated opening.

Still another object of the invention is to provide for automatically feeding cigars from a supply to a cigar transfer which carries them to a piercing position and further to an enveloping position.

With these and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then particularly pointed out in the claim hereunto appended.

In the accompanying drawing:

Fig. 1 is a view in side elevation, partly in section of the improved cigar piercer;

Fig. 2 is a view in end elevation, partly in section on line 2-2 of Fig. 1;

Fig. 3 is a view in cross-section on the line 3-3 of Fig. 1;

Fig. 3a. is a fragmentary detail View, partly in section, showing the piercing point;

Fig. 4 is a diagram in side elevation, partly in section, showing the arrangement of a piercing device in connection with a cigar enveloping mechanism; and

Fig. 5 is a plan view from line 5-5 of Fig. 4.

The apparatus illustrative of one way in which the piercing operation may be carried into effect may, as shown in Figs. 1 and 2, comprise the combination with a cigar support, of a locating thimble arranged to fit one end of the cigar, a piercer arranged centrally of said thimble and means for first moving the thimble and cigar relatively to one another to locate the cigar end, and then moving the piercer relatively to the end of the located cigar to pierce the same. Preferably a heater is arranged to heat the piercer to retain the hole caused by piercing, after the withdrawal of the piercer, and preferably the support comprises a transfer having a to and fro motion and including cigar gripping elements arranged to receive cigars from the delivery of the cigar machine and transfer them into the range of action of said piercer.

In the best constructions this transfer takes enveloping mechanism which may enwrap thecigars, including the pierced resistant material.

This apparatus may be varied widely in construction within the scope of the claims, for the particular device selected to illustrate the invention is'but one of many possible concrete embodiments of the same. The invention therefore is not to be restricted to the precise details shown and described, nor to the particular embodiment chosen as illustrative of the invention.

Referring to Figs. 1, 2 and 3, the frame lil of the cigar machine supports a shaft which carries the finishing knurler l2, an automatically operated part of the cigar machine.

The shaft H is rotated by a pulley l3 splined thereon and reciprocated axially by a lever I4 connected by a rod l5 to a lever (not shown) actuated by a cam (not shown) of the cigar machine. By means of a belt, a pulley l6 splined on shaft transmits the motion of shaft H to a pulley splined on a shaft l8 supported in a pedestal l9 and slidable in a sleeve 20 held by a pedestal 2|. The shaft I8 carries the piercing pin 22 and, is reciprocated axially by a lever 23 connected by a rod 24 to a cam lever 25 having a roller 26 held in engagement with a cam piece 21 by a spring 28.

A pin 29 carried by a block 30 slidable in a 1ongitudinal slot of lever 23 engages a slot 3|a; in a slide 3| supported by a guide 32 mounted on frame It]. To the slide 3| is fastened a rod 33 which is guided by a bushing in pedestal 2| and carries the header block 34. A spring 35 anchored to pedestal 2| and hooked to a post 36 in slide 3| tends to hold block 34 in its forward position shown in full lines in Fig. l, in which a locating device 34 engages and locates the cigar.

The pin 22 slides in a block 31 heated by an electric heating cartridge 38, the block 31 having a heat insulating covering 39 and being supported adjacent to pedestal 2| by a clamp bracket 40.

The cigar C is held in clamps or gripper fingers ends, in moisture 4|, 42 of a transfer arm which takes the same from the knurling position C and. delivers it to piercing position C (Figure 1). The transfer arm and its associated mechanism are the same as shown and described in my copending application, and since they do not form a part of my present invention, further description and disclosure is deemed unnecessary.

When a cigar has been delivered to position C the cam 2'! then advances the pin 22. allowing spring 35 to also advance block 34. The latter stops upon engaging with the head of the cigar C and pressing its tuck end against a stop 58 attached to frame l0, but, by virtue of the slot in slide 3|, the pin 22 moves on and enters the cigar. Cam 21 then withdraws pin 22 while block 34 remains in position until pin 29 of lever 23 has reached the end of slot 3 la when both pin 22 and block 34 recede together until they have reached the dotted positions shown in Fig. 1. The clamps 42 are then opened to discharge the pierced cigar by mechanism described in said above referred to application but not illustrated herein.

In a preferred form, Figs. 4 and 5, illustrative of the present invention, the improved piercing apparatus is provided with a turret cigar carrier and is also shown as embodying a cigar enveloping mechanism. Cigars C taken from a suitable source are advanced by the pusher fingers H of an endless conveyor 12 to a transfer arm 13 operating in conjunction with a pusher '14, such as shown in U. S. Patent 1,964,411 to R. J. Beutel.

This transfer inserts one cigar at a time into one of the holding pockets of an intermittently revolving turret 15, the jaws 16 of which are actuated by a stationary cam 11 and springs 18. In the entering position Cl, the cigar is turned at right angles to its original position C on conveyor 72. In position C2, at the next stop of turret 15, the cigar engages with the header block 34 and the piercing pin 22, the arrangement of the piercing apparatus being the same as in Figs. 1, 2 and 3. In position C3, after turning through 180 degrees from the entering position Cl, the shoulder 5 on a suitable cam on cam shaft S opens the jaw 16, and by the action of a pusher P moved outwardly by another suitable cam (not shown) on the cam shaft S beyond the turret the pierced cigar is discharged into a transfer 19 which after another degree turn into position C4, delivers the cigar to a second transfer arm and pusher combination 80, 8|, which in turn inserts the cigar into the receiving pocket 82 of a Cellophaning machine 83 such as described in the patent specification above referred to. When arrived in this position C5, the cigar has been turned on its axis one complete revolution since entering the piercer turret l4 and thus is in the same position as at Cl.

As it enters the turret 83, the cigar C5 is enveloped on three sides by the Cellophane web W, supported in guides 83a, the latter being subsequently lapped on the fourth side by folding arms 84, 85, and its ends tucked and creased by devices shown in the patent cited. In the Cellophaning turret 83 the cigar is turned through 2'70 degrees and the wrapped pierced cigar is finally deposited on a table by a 90 degree transfer similar to transfer 19 in the same position as when taken from the conveyor 12, with the wrapping seam at the bottom,

What is claimed is:

The combination with means including sets of relatively yieldable grippers for gripping cigars between their ends and intermittently forwarding them, of a piercer, means operating said piercer to axially pierce successive cigars in said sets of grippers during dwell periods in their movement, a locater for engaging the successive cigars in said grippers before they are pierced to center them with respect to said piercer and to locate them in proper endwise relation to a Wrapping mechanism, and mechanism for wrapping the pierced cigars.
