Patented ct. 27, 1931 UNITED STATES PATENT OFFICE ALBERT F. DILLON, OF RICHMOND, VIRGINIA, ASSIGNOR TO P. LORILLARD COMPANY, OF RICHMOND, VIRGINIA, A CORPORATION OF NEN JERSEY TRANSFER MECHANISM Application led August 17, 1929. Serial No. 386,628.

This invention relates especially to a mechanism for transferring foil wrapped cigars from a foil wrapping machine to what is known as a banding machine. However, the transfer mechanism is applicable to other uses than this specific one.

Specifically, the invention consists in the provision of a mechanism for transferring the cigars from one machine to the other, thereby reducing the cost of the cigars to the consuming public, because the use of such transfer mechanism will reduce by two the number of operatives now employed as attendants to a pair of wrapping and banding machines.

In a broader aspect, the invention consists in a transfer mechanism wherein the articles, while being delivered from one machine to another of successive machines, are turned endwise so that they are reversed end for end between one machine and the next machine by which they are handled.

A still further object is to produce such a transfer mechanism consisting of a comparatively few number of parts, all of simple construction and arrangement.

lVith these and other objects in view, the invention consists incertain details of construction and combinations and arrangements of parts, all as will be hereinafter more fully described and the novel features particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a plan view of the transfer mechanism, a portion of the foil wrapping machine and the banding machine being shown more or less in outline;

Fig. 2 is a side elevational view of the apparatus illustrated in Figure 1;

Figs. 3 and 4 are plan and elevational views, respectively, of the table for the transfer mechanism;

Figs. 5 and 6 are plan and side elevational views of the loader and ejector;

Figs. 7 and 8 are plan and elevational views of the transfer turret; and

Figs. 9 and 10 are plan and elevational views o-f the banding machine feed which constitutes a part of the transfer mecha nism.

The foil wrapping machine 10 and the banding machine 11 are shown more or less i n outline, as before mentioned. Intermediate these two machines there is a table 12, constituting a support for the transfer mechanism proper. This transfer mechanism preferably consists of a turret 13 having a series of supports or pockets 14 arranged in pairs at diametrically opposite points thereon. Said turret is mounted on a shaft 15, journaled in a bearing 16 in table 12. The turret is located above the table and below the table there is a Geneva disk 17 mounted on shaft whereby the shaft and turret may be intermittently rotated by a cam 18 on a cam disk 19 periodically engaging in the recesses 2O of the Geneva disk. 10 hold or lock the turret stationary during the interval between its successive movements, disk 19 has thereon an arcuate shoe 2l adapted to succesively engage the curved surfaces 22 of the Geneva disk. v

The cam disk 19 is mounted on a shaft 23, journaled in bearings 24, 24EL in table 12, and a plate 25, respectively, supported below said table by a depending bracket 26. Cam shaft 23 has a bevel gear 2T, which meshes with a similar pinion 28 on a shaft 29, journaled in a bearing 30 in bracket Shaft 29 also carries sprocket 30 that is driven by a chain 3l from a sprocket 32, mounted on one of the shafts 33 of the wrapping machine. VVth the connections thus far described, it will be seen that in the form of apparatus shown in the present instance, the turret 13 will be intermittently moved, each movement thereof carrying one of the pockets or supports 14 through an arc of 90. Formed in the upper surface of table 12, there are a pair of grooves 34 for a pair of loading and ejecting slides 35. These slides are continuously reciprocated by connections operative from a shaft 36, this being the shaft that is ordinarily used for operating the ejector fingers commonly found in the standard foil wrappingmachine on the market today. As shown in Figs. 2, 5, and 6, the operating connections between the shaft 36 and the slides 35 consist of a drive lever 37 mounted on said shaft and connected by a link 38 to an operating lever Y 39 pivoted on a shaftl40 which is journaled Y 1y extending projections 44, and projecting 'Y io in brackets 41 depending from table 12. Operating lever 39 is connected by a link 42, pivotally attached to a cross bar 43 which connects the two slides together. Projecting from the slides 35 at their ends nearest the foil wrapping machine, ,are a pair of upwardupwardly at the opposite end of said slides are projectioiis45; As shownin Figs. 1 and 2, the cigars are delivered from theio'il wrapping machine onto the slide 35 somewhat in advance of what may be termed the loading projections 44, so that upon reciprocation of the slides in a direction to move the loading proj ections toward the turret, ,one of the cigars .would be moved y onto Yone, of the ysupports-,14`pofjthe turret. "At the same time, r

the ejector extensions-45 at the opposite end ofthe/*slides will engage and ejecta cigarl carried byV the support 14v of the turretthen locateddiametrically opposite the support on whichthe kcigar is being loaded.` In this way, there is a simultaneous loa/ding and discharging of cigars from'a pair of diametrically opposed supports 14 of the turret, and as the cigarl discharged will have passed through an arc of 180O from the point at which it-was placed on said support, it will be seen that the discharged cigar, when it reaches the zbanding machine,will have be n turned end-ior'endas compared vwith t e position it occupiedfwhen delivered from the foil; wrapping machine.

io lfacilitate feeding. the ycigars to the banding machine after they have been discharged rom the pockets or supports of the turret,;, each cigar, after `it has been so discharged, is given anv endwise movement as illustrated infFigure 1. VThis is accom- 54 ,is mounted on a lever 56, which, in turn, is,

mounted o n ashaft 57, journaled in bearings 53m table 12 and plate 25. Also mounted on by reason of the spring being interposed between'said head and the arm 47.

To retain the cigars onthe supports or ypockets 14 of the turretrwhile being transferred from the oil wrapping machine t0V the banding machine, each pocketisprovided with whatV will be termedv a door 63, located above `.the supports 14 but spring pressed downwardly so as to rmly grip a cigar positioned on the'y support-.1Y However, as! cigars.

are being pushed onto-the successivesupports as. the latter comey into registry with the "loading devices, doors 63 are slightly elevated by a cam surface 64 on the cross bar 43 of the slides, engaging a roller 65 journaled in depending arms66roi a lever 67, pivoted at a suitable pointbeneath the turret.Y The free extremity of said lever 67 is adapted to beslightly 'elevated by said carin surface, into engagement with the doors 63, sofas to also slightly raise them andhold them in raised position until a cigar has been .pushed onto the support 14 andthe next movement imparted to the turret.V
