(Cl. 131-61) This invention relates to the manufacture of filter tip cigarettes and more particularly to improvements in or modification of the type machine shown and described in the specification copending application S. N. 696,206 now Patent 2,604,099 filed September 11, 1946, by Hyman Policansky and. is directed specifically to a means for feeding filter plugs to the transfer wheel forming part tobacco length, said pins being subsequently withdrawn It has been found that the presence of these pins and their subsequent withdrawal tends to hinder a proper abutment of the succeeding tobacco length with the filter plug.
vOne of the primary objects of the'present invention is to overcome the above difliculty, and to this end mechanism for feeding filter plugs to the transfer wheel is provided to present them to said transfer wheel and mechanism operative upon rotation timed relation to said impaled upon said pins.
In order that the invention may be clearly understood, reference is directed to the accompanying drawings, wherein": x

Figure 2 is a section on the line 22, Figure 1.
Figure 3 is a sectional elevation of the transfer wheel shown in Figure 1. Y b
Figure 4 is a longitudinal section at right angles to Figure 3.
of the transfer wheel With reference to the drawings particularly Figure 1,
tobacco issuing from the hopper of a continuous rod cigarette making machine, and having been compressed into rope form enters the peripheral groove 5 of a'section wheel 6. The section wheel 6'is rotated and cutting knives 7, operating in transverse slots 8 cut tobacco rope and carry forward the severed tobacco length to present it to a transfer wheel 9 which is rotated, and
ultimately deposits the tobacco length upon a"continuously moving paper web 10, a filter plug 11 being interposed between the adjacent ends of the cut sections 12a of tobacco rope by apparatus hereinafter described.
' The foregoing mechanism forms part of the invention the present invention is of said transfer wheel in, pins whereby the presented plug is through the 1-2 of disc form having-a radial. abutment 13 which converts the member 12 into a con-" I revolves about particular device selected to illustrate the invention is by comparison 2,742,907 Farmed Apr. 24, 1956 ice veyor, an enclosing casing 14 being furnished and conretaining fingers employed for the purpose of keeping the last plug slightly above the veyor 12.
It is conventional in the art of dispensing to position a number of articles in a vertical column within a housing in such a manner as to facilitate the release of inperiphery of rotating condividual articles as a pusher member is moved in po-:
sition to engage such article for moving the same to another location as shown in many U. S. patents, such as 2,077,896 granted to C. E. Quick on April 20, 1937, and 740,998 granted October 6, 1903 to J. A. Williams.
The conveyor 12 and the transfer wheel 9 are driven in timed relationship with one another by suitable gears 36 and 38 respectively. As indicated in the drawings of the diameters of the plug conveyor gear and the transfer wheel gear, it is apparent that the ratio of the gears is 1:2. The abutment 13 conveys the plug to a point where it is presented to the periphery of the transfer wheel 9, the casing of the conveyor being broken at this part (see Figure 2) to permit the passage of the abutment 13 and feed of the plug. The transfer wheel 9 is fitted with retractable pins as herein-after described, which at the moment of presentation of the filter plug 11 are protruded to engage in the plug and carry it around the transfer wheel 9 until it is introduced between successive tobacco segments 12a, as delivered from the section wheel 6, determined point in the circle of rotation of the transfer wheel where it is retracted to an inoperative position,.
protruded to pick up the next filter plug Figure 1, the transfer wheel 9 is provided with two sets of rectilinearly retractable conveyor pins 20, 20a, one set shown in its retracted or inoperative position and the other in its protruded or operative position. The pins 20, 20a are mounted in slide blocks 21, which are restrained by slide block guides 22. The slide blocks are actuated by a cam 23 and cam follower rollers 24 and by springs 25. The cam 23 has an elongated boss which may be bushed to provide a bearing for drive shaft 26 to which the transfer wheel is pinned at 27 through the transfer wheel boss 28. The cam 23 clamped in a bracket stand 29 and the transfer wheel the stationary cam. A cover plate 30 completes the seal against escape of lubricant and entry of dust.
The invention hereinbefore described may be varied in construction within the scope of the claims, for the but one of many possible embodiments of the same. The invention, therefore, is not to be restricted to the precise details of the structure shown and described.
The foregoing construction is similar to that disclosed in the aforesaid copending application Serial No. 696,206
