r "Thisinvention relates toiinprovements in cigarette machine cutoffs, particularly to-the type inwhich the cutoff blade is moved in an orbital path intercepting the path of the cigarette rod and at the same time following therod. v p

' The main object of the present invention is to provide a cutoff mechanism in which the cutoff blade and the ledger plate are carried by the sameframe for movement in unison,

thus avoiding thelnecessityfor separate reciprocation of the ledger plate as has hitherto commonly been the practice; In this man 7 ner, the ledger plate is given the same '16 smoothicircular motion that thefknife' receives, thus veliminating'one sourceof vibration: Moreover the extra parts for reciproeating the ledger plate are dispensed with.

Also when the ledger plate is separately l reciprocated, while the knife ispmovediinan orbital path, there is a-small but objectionable longitudinal differential movement bea tween the ledger plate. and theblade which varies the clearance between" the ledger plate 2 and knife and resultsin imperfectcuts Another object of theinvention is to provide simple and efi'ectivemeans for rotating the blade as it travels along its orbital-path. Still another object of the invention is to provide a three point connection between the I V b n Fig, 1, the cutoff s dr ven from the main I frame carrying the blade and ledger plate and the means supporting the 'frame for movement, in order to resist the tendency of p the frame to sidesway about two points as an axis and to .resist the torque resulting from driving the blade. 1 i j b With these and otherobjects not specifi cally mentioned in View, the invention con- L v p e p v ported 'by a' housing '22 andhousing cover 23 'inibearings 24 held by aj sleeve 25 on V sists of certain constructions andcomb'inations which will. be hereinafter fullydescribed and then specifically set forth in the claimshereunto appended. 7*

i In the accompany drawings {which form a partof this specification and in which like characters ofreference'indicate the same or like parts; Fig. l is a front elevation partly in section of a cutoff mechanism constructed 7 in accordance with the invention; Fig; 2 is a detail-view in front elevation and partly 1,- then-full lines showing the blade in cutting positionran'd the dotted lines in the mid-position between cuts; Figfi- 3 is": a side. elevation of thedevice' shown in Figj-lyFig'fd'isia planview'of the devicesho wnin Figill' In carrying? the invention into'efiect there-is provided a flying frame, a cutoff blade of the usual. kind and as cooperating le'dger plate both the cutoff blade and the cooperating ledger 'plate being carried by-*; 7 said frame for movement: in' unison therewith,; and means for moving said frame in an orbital path tocause the blade and the ledger plate to operate on' ther'od. In the best constructions said mansincludes cranks supportingtheframe; I Preferably the frame supports :th'efblade'and ledger plate respectively on uopposite sides of the: rod. The best constructions: further include mechanism for the; invention isbut one of many possiblec'oncrete emjbodimentsof thesame. gTheginvention therefore is not to be restricted to 1 the precise details of anddescribed.

the structure shown Referring nowio the drawings asshown drive shaft 10 @of (the cigarette; machine through gears 11 and-12 thelatter on the vertical drive shaft 13 which is'supported bybearings 14 and 15in a sleeve 16. On the=- 1 upper end-of the shaft 13 is mounted a gear '19 ,Whiclrthr'ougha bevel gear 20 drives the horizontal crankshaft" 21.; Thelatter i s-supshaft- 21.. I I g I Flying supports for the knife carrying 7 frame are provided consisting of crank pins '32}, 33 and34 on crankshafts 21 and '27, the latter two shaftsbeing journaled-in bearings 28 and 29 held in by sleeves 30 i "and 31,respectively. Crank pins 32;33 and 34 by ineans'ofbearings 35, 36am f.

I wjlrespec tively," support the frame; =38 for fly- '--50 2 in-section of the cutoff blade shown in: Fig, ting movenien't in a"; circular orbital path.

The frame 38 together with the cover 39 forms a housing'in which the bearings of crank pins 32 and 33 are mounted while in i a vertical extension of the frame 38 there mounted a spiral gear 44 driven from av spiral gear 45 fixedly mounted on the crank pin 32. The spiralgear 44 is integral with asleeve 46 supported by bearings 47 and carrying an arm L8 mounting the wafer cutoff blade 49. A cover 50- serves as. an oil catcher-to keep oil off the cigarette rod shafts 21', 26'a11d 27' have counterbalanees 51 to, balance the weight 'of the revolving frame 38'. I

A grinding wheel 52' is held by. a bracket 53 which is mounted on an adjustable rod 54 held by alug 5'5 slidable in a bracket .56 mountedontop of the housing- 22. Ad-

justment of the lug 55 -is accomplished by means of the'handwheel 57, the rod 58which is held by a bracket 56, which ro'd has its threaded end enteringinto lug '55.. The grinding wheel=52 is protected: by a cover 59 hinged ona stud 60, while a cover 61 hinged on stud62 protects the knife49. A

burr dressing wheel 63- is held by a fork- '64 ona rod 65, adjustably mounted in a bracket G'dattached to housing 67 which forms an extension of housing 22. A slot both-supported by saidframe, and means formoving said'frame in an orbital path 68 in thecover' 61 permitsthe latter to be opened without interfering with the rod 65. Stationary guide tubes 69 and 70 for the cigarette rod 0 are held byhousing 67. These guides are cut away at an angle on their undersides to provide afair way for the ledger plate tothe' rod. An advantage of the above construction is that shorts drop 'out there' instead of being delivered to the collecting mechanism.
