To all whom it may concern:

Be it known thatI, RICHARD E. Bosn- WARNE, a citizen ofthe United States, and residing at Covington, in the county of Kenton and State of Kentucky, have invented a new and useful Improvement in Cutter- Heads for Cigarette-Machines, of which the following specification is a. full. disclosure.

This invention relates to severing devices for severing a continuously moving work into determined or measurel lengths, having utility in cutting ropelike cigarette stock inclosed in a paper easing into cigarettes, to which the invention is primarily directed.

The cutter has a rotary motion and during its rotation is carried in an orbital or circuitous path around a work guiding member to intervally intersect the work guiding spout for severing the work into determined or measured lengths. The cutter therefore has a planetary motion, rotatively about its own aXis and about the axis of its rotating support, as well as a lateral or longitudinal movement in motions of reciprocation and in one direction at a rate coincident with the feed of the Work. The guiding spout moves unitarily with the cutter in its reciprocating motion, but'non-rotatively confined. This provides'for a continuity of motion of the moving parts and work.

An object of my invention is to provide a severing device wherein the general organization adapts itself to the use of a plural number ofcutters moving as a unit in an orbital path to successively intersect a work feed spout in either the singular or plural number, with the cutting edge of the cutters continuously guided in a circular path and when bisecting the spout.

Another object of the invention consists in providing a stationary journal or axle member as an axis about and upon which planetary cutters are rotatively and trans- V verselv movable, in either the singular or plural number, adapted to be intersected by plural'number and as a support for a feed spout member in either the singular or the rotating cutters, and moving as a unit therewith transversely or longitudinally.

the work or cigarette stock during a severing interval.

Various other features and advantages of the invention will be more completely disclosed in the description of the accompanying drawings, said drawings forming a part of this specification, containing letters of reference with like characters denoting corresponding parts throughout the several views, of which Figure 1 is a top plan view of the severing device illustrating two cutters as a unit revolving ina common orbital path ecccntrically about. a feed table which the knife successively intercepts for severing the material moving through the feed tube. Fig. 2 is an end elevation thereof with the carrier devices for feeding the stock to the feed tube omitted. Fig. 3 isa partial section taken on line Fig. 2. Fi 4 is an elevation of a modified form of stock guiding or feeding member illustrating a plural number of feed tubes. Fig. 5 is a view similar to Fig. 2, illustrating the cutter devices in the singular number. and Fig. 6 is a partial sectional view on line 66 Fig. 5.

Referring to Figs. 1, 2, and 3 of the drawings, which illustrate the preferred embodiment of the invention in the employment of a plural number of cutters, 1 indicates a main frame structure supporting the severing devices and comprising a component of acigarette machine.- The cigarette stock in the nature of a rope-like strand is fed from the forming devices not shown upon a belt or tape 2 having one of the loops engaged overthe pulley 3 properly located so that the cigarette stock is fed in alinement with the feed tube of the cutter or severing devices;

A bracket is secured upon the main frame 1 having an arm 5 projecting forble of sliding axially thereon. The hub 16' or series of feed spouts.

wardly for supporting a bearing member or axle6. The bearing member 6 engages into a bore formed into the hub end of said bracket arm 5, and is rigidly secured to the arm by the screws 7 Adjacent one end of the bearing member 6 I provide an annular non-rotative axially movable spout member 8 having a stud 9 axially projecting from one side and extended into a bore 10 formed in the end of the bearing member and concentric therewith. The spout member 8 has a tubular spout 11 projecting eccentrically from its opposite side with the spout bore extended through said member 8 and continuing with a tube 12 secured to and project-ing from said member 8 and guidin 'ly extended into va bore 13 longitudinadly through the bearing member or axle 6. The

stud 9 and tube 12 serving as means for nonrotatively mounting the spout member upon the bearing member, but free to slide thereon axially. The mouth of the spout and axis of the guiding bore through the bearing member is located in alinement with the moving cigarette stock fed from the carrier tape 3.

A cam wheel 14 which also serves as rotative support for the circular cutters or knife 15 is concentrically j ournaled upon the periphery of the bearing member and capaat one end is provided with a coupling collar 17 fitting into anannular groove formed in the periphery of spout member 8 for connectingsaid member with the cam wheel to axially reciprocate the same and move the guide spout with the moving cigarette stock at a corresponding rate of motion'during a severing period, necessary for 'making a straight out across the moving stock. A gear 18 is secured upon the opposite end of the hub of the cam wheel in mesh with a gear 19 suitably journaled and supported and preferably provided with an enlarged or elongated face to maintain a constant full width mesh with the gear 18 in its sliding motion. The gear 19 is driven from a suitable source and at a proper speed. con1- mensurate for cutting the continuous cigarette stock into determined lengths.

The construction of the parts above described for the purpose herein is applicable to any of the styles for severing device shown in the various modifications, for either a single or plural number of cutters operating across a single feed spout or tube and from a general aspect, for the double In the latter instance provision need only benmade in the bearing member for the requisite number of passages through the spout and bearingmembers. In all instances due regard should be had for such mechanical variation required as to the design of cam out meant/e upon the cam wheel and therefore a detail description of one will be suiiicient for the purposes herein. The web of the cam wheel is provided with a laterally extended ear 20 having one side surface in plane with a wall of the opening 20 formed in the cam wheel web, to receive and support the bearing block 21, which issecured, adjustable radially, by the screws 22, 22, respectively passing through oblong slots in the ear 20. The bearing block 21 supports a shaft 23 axially coplanar with the axis of the cam wheel and longitudinally confined by the shoulder of an annular boss 2i integral with the shaft, at oneend of the bearing, and by a collar 25 at the opposite end of the bearing. The end of the shaft 23 projecting beyond the annular boss 2 1 provides a screwhreaded stud 26 for supporting the circular cutter 15 which is securely clamped to the shaft 23 by a nut 27. The cutting edge of the cutter extends into an annular concentric groove 28 of the spout member 8, so that it will intercept the spout bore in its orbit. As illustrated the plane face of the cutter at its cutting edge engages with the adjacent groove wall serving to guide the knife, avoiding any vibratory motion of the knife, and provides a shear action across the spout bore in addition to the rotary cutting action of the cutter. It is desirable to pendent of its orbital motion whereby the cutter has a planetary motion. The cutter t and its shaft are independently rotated by a belt 29 which engages around and into the annular groove 31 formed around the periphery of the shaft boss 24: and in a single cutter severing device the belt loops around and engages into an annular pulley groove 32 formed upon the periphery of the nonrotating spout member 8.

In the double cutter form of severing device the belt runs engage with the pulley groove of the spout member and upon opposite sides thereof, with the belt loops respectively connecting with the belt grooves of the cutter shafts as shown in Fig. 2. The orbital motion-at the belt loops imparts a driving motion to the belt by reason of its frictional engagement with the non-rotative spout member, with the diameter of the belt surface of the knife determining the rate of rotation of the cutter upon its own axis, which is preferably a high speed rate.

With a single cutter and single feed tube or spout intercepted by the cutter, only one severance is made to each revolution of the cam wheel. The severing performance however can be increased by either multiplying the number of feed tubes within the orbital path of the cutters or by multiplying the number of cutters operating across a single feed tube or spout, or either a combination in the plural of both cutters and feed tubes. Thus it will be apparent that in a unitary compact structure the capacity can be materially increased over the type of cutter heretofore employed for cutting cigarette stock into definite lengths.

In Fig. 4 a .double spout or feed tube member is illustrated, with their feed bores arranged relatively diametrically upon opposite sides of the common axis, and of duplicate construction and as heretofore de-. scribed in the singular, noting however, that the bearing member 6 must be provided with longitudinal guiding bores 13 in number equal to the number of feed tubes employed to guide the severed lengths to a point of delivery.

It will be observed that the feed or guide spouts are located between the axis about which the cutter revolves and the axis of the cutter, enabling the cutter edges to be continuously in mesh and guided within the groove 28. This enables the cutter edge to be adjusted to approximately contact with the bore edge of the spout imparting a shear action uponthe material to be severed,- producing a sharper cut of the paper casing inclosing the cigarette stock.

To translate the guide spout and cutter longitudinally with the feed of the work, the cam rim 33 of the cam wheel 14 is provided with opposite cam surfaces 34, 34, intervening and respectively engaging the non-translating or relatively stationary guide rollers 35, 35, (see Fig. 1) suitably journaled upon the bracket 4. The cam surfaces as a unit are of such outline or pitch as to move the cutters longitudinally with the work when they intersect the guide spout and in a retracting or opposite direction during a non-severing interval, and the nonsevering interval coordinates to the feed rate of the work for determinate lengths into which the work is to be severed. It will be understood that by forming the cam faces at various angles the transverse or reciprocating movements of the cutter and feed spouts will be regulated to cut the-work into any desired lengths, and that various constructions and outlines could be used with the apparatus herein to meet the various demands commensurate with their rotative speed, and number of cutters. It will also be understood that various forms of transmission means may be employo'd for the cut-' having a iii ters, but the use of a belt is preferred when possible, by reason of its smooth running and noiseless qualifications.

Having described my invention, I claim 1.
