To all .whom t may concern:

'Beit known that I, lRickman E. Bosn- WARNE, a citizen of the United Sta-tes, and a resident of Covington, in the county of Kenton and btate of Kentucky, have invented certain new and useful Improvements in Cutter Heads for Cigarette Machines, of which the following is a full, clear, and eX- act description, reference being had to the accompanying drawings, forming partwof this specification. Y

My invention relates to cutting mechanism for severing predetermined lengths yof a continuously moving stock of material and has special relation tosuch cutting` devices when applied to sever into fixed lengths the. continuously i moving cigarette rod formed on .the cigarette machine in which the. paper covering4 .is wound around the rod of tolbacco and the-rod delivered to the severing mechanism continuously. tube ultimately severed into individual cigarettes of. the desired uniform length.

For such cutting mechanism it .is obviously .necessary that the cutter shall be moved not only transverse the rope, but also lengthwise synchronously with the advance.

of the stock. The usual methods to accomplish these movements have been to provide for an orbital movement of the knife: at right angles to the lengthwise movement and to mount t-he cutting knife with its transverse actuating devices on a proper carrage and to shift the entire carriage by crank throw or cam devices which must carry the weight ofl the cutter mechanism, necessarily causing a shock and undesired lvibrations with each recip-rocation of .the carriage, and obviously placing a serious limitationin the speed with which the mechanism can be operated, in addition to causing undue wear and necessitating heaviness and weight of parts to withstand the shocks.

lt is theobject, therefore, of my invention to furnish a construction of a minimum numberV of parts, in which the highest speed may be lmaintained'without shocks and jars due to reciprocation, and in which the usual weight of the parts is avoided with minimum wear and with readily renewable wearing parts.

One 0f ythe important features of my inventionconsists of the constructionin which 1922. Serial N0.I.5'49,.349.

the necessity for the reciprocation cf Vany carriage 'forthe cutting mechanism is obvia-tcd and the knife isgiven an orb-ital movement ,parallel with and at the same speed as the longitudinal movement ofthe cigarette rod, so that with a single throw of the actuating crank, the transverse and longitudinalmovement of the cutter is atta-ined.

Another feature of importanceis that the cigarette. tube through which the cigarette rod is fed is the only part'ofthe mechanism which requires reciprocation, and this tube may bei made. exceedingly light so that there is no' appreciableshock or jar in the opera.A tion and a. very high speed may beattainedV without detriment or undue wear. j

Another .feature of improvement consists. inthe use of the. connecting rod through which the cutting ,knifeis givenits orbital movement for connection with thecigarette tube toiolotain the reciprocating movement and the. location. of this coupling near the center of thetu-be so as to obtain afsubstantiallyvertical transverse movement for the knife at its cutting edge'by controlling the angular position of the knife cutter head on the connecting rod.

Another feature of the invention relates to the adjustment of the knife relative to the cut-off tube opening, so as to make the cut at t-he tangential angle on the orbit of the actuating crank required for the length of the cigarette andthe longitudinal movement of the cigarette rod.

Still another feature relates to the construction of the knife ledger of such a size that the cutting knife may be adjusted at its lower edge to match for automatic operation.

These features and others will be more specifically referred to in the course of the description that follows, in connection with the drawings, in which- Figure l is a side elevation of the right side of the machine;

vThe cuttakes place on a tangent to the crank pin circle andas the cigarette rod is moving at a constantrate ofspeed, when the reciprocation of the cutter is increased this` tangent vwill be'more nearly vertical than when the reciprocation of the cutter is decreased. I am able therefore by adjustment of the cutter head vertically to raise or lower the cutting edge of the knife with reference to the ledger disk so as to obtain a vertical cut of the cigarette. After the knife has severed the cigarette rod it will then swing slightly away from the ledger plate and in its upward movement to pass the advancing cigarette rope, it will then be moving longitudinally, somewhat faster than the rod, so that there is no danger of interference.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
