' CUT-OFF MECHANISM FOR CIGARETTE-MACHINES.

Specification of Letters Patent. 7 Patented Dec, 10, 1918,

Application filed June 21, 1917. Serial No. 175,993.

To all whom it may concern:

Be it known that I, ELBERON D. SMITH, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Cut -Ofi Mechanism for Cigarette-lVIachines, of which the following is a specification.

This invention relates to an improvement in cigarette machines of the continuous rod type, and it has for its main object the production of a simplified cut-off mechanism whereby a continuous rod is severed into individual cigarette lengths. A further object is the production of a cut-0E mechanism lighter than those heretofore known and better adapted for high speed on this account. The invention consists in certain parts, constructions and combinations which will be hereinafter fully described and then specifically set forth in the claims hereunto appended. v

In the accompanying drawings, which form a part of this specification and in which like characters of'reference indicate the same or like parts, Figure 1 is a front elevation, partly in section, showing a device constructed in accordance with the invention; Fig. 2 is a frag nental plan view taken on the line 22 in Fig. 1 and Fig. 3 is an end view taken on the line 33 in Fig. 1. The particular device selected to illustrate the invention is but one of many possible concrete embodiments of the same.

The invention, therefore, is not to be restricted to the precise details of the structure shown and described.

Referring to the drawings, 4 indicates the bed of a cigarette machine of the continuous rod type, and 5 indicates the legs at one end of the bed. Rising from the bed 4 are two supports6 and 7. The supports 6 and 7 are respectively provided with rectangular bearings 8 and 9.' Mounted in these bearings is a bar 10 having at each of its ends a rectangular block 11 secured to the bar by means of tapered pins 12. The bar is thus slidably but non-rotatably mounted in the supports.

Means for reciprocating the bar are provided, and this means includes a boss 13 pinned to the bar 10 and having a pendent boss 14 in which is secured a stud 15. Upon the stud 15 is mounted one end of a pitman 16, the other end of which engages a crank pin 17 secured on the disk 18, which disk is mounted upon the upper end of a vertical shaft 19. The shaft 19 runs in bushes 20 A fast in a sleeve bearing 21 supported by the bed 4 before referred to. Upon the lower end of the vertical shaft 19 is secured a bevel gear 22 and this bevel gear is in mesh with a bevel pinion 23 fast upon a horizontal shaft 24 which is one of the main power shafts of the cigarette machine. The bar 10 is thus reciprocated by the mechanism just described, and one complete turn of the 'crank pin is made for each cigarette severed from the continuous rod formed by other mechanism mounted upon the bed 4 but not here shown. A groove 25 is'formed on the lower part of the disk 18, and in this groove runs a belt-26. This belt is for the purpose of driving a pasting mechanism supported by the bed 4 but not here shown. Projecting from the boss 13 is an arm 27 inclined downwardly and terminating in a ledger plate 28 having an aperture 29 therein through which the cigarette rod moves. It will be readily understood that this ledger plate will move or reciprocate back and forth with the bar 10.

A cut-ofif device is carried by the bar, and a this cut-off device includes a sleeve 30 loosely mounted on the bar 10 adjacent the boss 13. Clampedto this sleeve at separated points 31 and 32 are two arms of a bracket 33 carrying at its outer end a shaft 34 running in suitable bushes held in posi tion by means of the clamp screws 35. The shaft 34 carries a circular knife 36 of well known construction, this knife being mounted at one end of the shaft. The other end of the shaft 34 is provided with a pulley 37 over which runs a' belt 38. The belt 38 also runs over a larger pulley 39 which is its driving pulley. The pulley 39 is driven by an adjacent pulley 40, the two being secured together or formed integrally. These two pulleys 39 and 40 are loosely mounted upon the bar 10 between one end of the sleeve 30 and the end block 11 adjacent the pulleys. The pulley 40 is driven by a belt 41 over-running it and a pulley 42 mounted on the shaft 24 before referred to. By means of the mechanism just described, the circular knife 36 is constantly driven at high speed.

Means are provided for moving the cut off device in and out of position to act upon the cigarette rod and this means includes what may be termed a controlling member comprising a casting 43 clamped to the sleeve 30, a stud 44 secured Within the casting, and a bowl 45 mounted upon the stud. IV hen the controlling member 4344-45 is oscillated in one direction, the bracket 33 will be oscillated downwardly and the circular knife 36 will be brought to the position shown in full lines in Fig. 3, which is the position it occupies when in engagement with a cigarette rod coming through the hole 29 of the ledger plate 28. The other end of the movement of the knife; that is to say, its position when it is out of engagement with the cigarette rod is indicated by the broken circle in Fig. 3. For the purpose of throwing the knife 36 out of position to act upon a cigarette rod, there is provided a spring 46, one end of which is hooked to the stud 44 and the other end of which is hooked to a post 47 rising from the bed 4 before referred to. For the purpose of moving the cut-0E device into position to act upon a cigarette rod, the bowl 45 lies between the jaws 48 of a forked lever 49 which is fulcrumed on a bolt 50 suitably secured in the bed 4. The end of the lever 49 opposite the forked jaws 48 carries a bowl 51, which bowl tracks on a cam 52 secured on the upper periphery of the disk 18 before referred to.

v The rise on the cam 52 is so positioned with respect to the crank pin 17 that the knife 36 will be moved into position to act upon a cigarette rod at about the middle of the forward movement of the cut-ofi device, at which time it has a traveling speed equal to that of the cigarette rod itself, so that a square out can be made. For the purpose of guarding the knife 36 there is provided a fixed guard 58 to which is hinged a movable guard 54; the fixed guard 53 is supported by the bed 4, and the movable guard 54 may be thrown down when access to the knife is desired.

In view of the foregoing, a detailed description of the operation of the device is deemed unnecessary and is therefore omitted in the interest of brevity.
