t This invention relates to---cuto1fs for continuousrod cigarette machines, particularly to cutoffs of thetype in which the cutoff blade is moved in an orbital path oblique to the cigarette rod to cause the edge ofthc blade totraverse the rod andto follow 1t s movement, without the necessity for longitudinal reciprocation of theblade and its driving'parts. v The principal object of the inventlon s to produce a cutoff of this type in which all the moving. supporting. and driving parts for the cutoff blade have smooth rotary motion such that the cutolf. is. substantially 'Vibrationless at. very high speeds, as 2000" or morecuts per minute. Another objectis'to prov de such acutofi inwhich all heavy rotating parts are inherently balanced, thus'eliminating vibration and the necessity for extensive counterbalancing. Another important object is to insure a square cut by providing, driving Inea-nsfor the blade which maintains the blade perpendicular to the cigarette-rod during the oblique orbital movementofthe blade. With these and other objects not spec1fi cally mentioned in View, the invention con sists-in certain constructions and combinations which will be her-einafterffully described and. then, more particularly pointed out in the. claims hereunto appended} i V In the accompanying drawings which form apart ofithis specification and. in whichllke characters of reference indicate the same or like parts: a a v "Fig. 1 is a; sectional plan vi-ew'of a cutoff constructed tion; V Fig. 2 is asideelevationof the cutofi, part- 1yv in section, with certain parts broken away Fig. 3 is anuend viewalong theline 33 'of Fig. 1,.a*lso partly'brokenaway; V

In the best constructions; said offsetaires are parallel toeach other; In the preferred form, the spaced flying mounts are carried on spaced parallel disks rotating respectivelyyon the offset axes The various means referred to may be widely varied in construction; with} in the scope of the claims, for the'particular device selected to illustrate the invention is but one of many possible concrete embodimentsfof the -same.

en axes'laterally olfset Referring to the drawings: The [table V of'the cigarette machine carries a stan-d' ll 7' Whichfsupports bearing. pedestals 1 2 and 13. A housing 14 is securedtobearinglQ, a flange 15 of thebearing 1.3Qfittingloosely into a ring 16 attached to the shaft 17 rotates i n'bearing12 andsupports at its innerenda circular disk 18 which, together with the similar paralleljcirculardisk similarly mounted on the shaft 19 inthe bearing 13,. drives the cutolf blade as herein: after described; The aXesIof the shafts-l7 and 1 9 are oblique to the'cigarette rods and are parallel and laterally offset from each" other, as shown in Figs. 1, 4E and 5, The two disk 20; A',l1orizont- al disks 18 and 20 are connected shy studs 21,. I

each of-which'has two olfset'bearing p01} tions in bearing'plates 22 and QZ-3-securedin thetdiskslS and 20 respectively; Thesestuds serve torimpart the driving movement given to disk'18,by means hereinafter described, to the otherdisk 20, and atthe sametime maintain the disks in The disks 18" and 20 carry respectively spaced flying mounts "26 for the shaft 24, on which shaft the knife 25 is rigidly mounted. These mounts have spherical bearing predetermined relationship.

portions for receiving the spherical ournals 24a and 246 on the shaft 24. The cooperating spherical bearings and journals proe vide a flexible universal connection between the knife shaft and the disksat each mount. A pin 28is attached to the shaft 2 1- and fits loosely into the block 28a, slidable in an axial slot ofdisk 18, thus preventing the shaft 2l from rotating about its own-axis. It is obvi- Since the disks are parallel and rotate together on parallel axes, the knife shaft will be held parallel and the 'blade'per'pendicular to the cigarette rod at all times and a per- .fectly square cutwill be made. i I

For lubrication purposes,the cover 80 of the bearing 13 is provided with an oil reservoir 31 and'disks 18 and 20 have annular oil grooves 32 connected by oil holes 83 with the bearing surfaces of the studs 21 and the shaft24. p I

For the purpose of driving the disks 18 and 20, the shaft 17 is provided with a gear 35 meshing with a gear 36 on vertical shaft 37 supported-in a housing 38 fixed at 39 to the bearingpedestal 12. The shaft 37 is also supported at its lower end by a bearing 40.

The'housing 38 terminates in a sleeve 41 which pro'ects into a lower housing 42.; The

upper en ofthe bearing {l0 projects into this housing 42 and carries suitable bearings for thesupport of the shaft '37. Thisshaft 37 has an eccentric portion 43 on which, by hearing 44, is mounted'a ring 45 connected with a slide 4L6 on a shaft {l9 ifor'recip rocating the ledger plate in synchronism with the rotation of the knife carrying disks18 and P 20. A sleeve 47 surrounding shaft 87 terminates in a recessed flange 4:8.which catches the oil dripping from the housing 38 and leads it to the bearing li, 1

The tubular ledger plate 54ismounted in suitable lugs-52 integral with the'slide46. Motion is imparted to the shaft 37 from the main shaft 'of the cigarette machine by a gear 55 meshing with a gear 56 mounted on a horizontal shaft 57 connected to .said maln shaftof the machine.

A suitable grinding disk 58isprovided in the path of the edge of theknife 25. This disk rotates on a shaft 59 adjustable on its 7 support 61 by a thumb screw 63 and is driven by the belt 69.

w It will be seen from the foregoing that a cutoff has been provided in which the cutofi blade is perpendicular to the rod and in which its edge follows the movement of the rodduring cutting, all without any reciprocating parts in 'the cutoff drive; and that in this cutoff the main driving parts are two smoothly rotating disks which are inherently balanced and vibrationless. In view of the foregoing further description of the operation ofthe improved cutoff is deemed unnecessary and is omitted in the interest of brevity.
