  • This type of machine being well knownin the art neither ing-of base 1, its inner end being in one with a movable ⁇ transverse member 3 slidable on two longitudinal guide rods 4 liXed to base 1.
  • Member 3 carries the vertical pivot 5 of a connecting rod 6 the other end vof which is pivoted at 7 on one of the linksof an endless chain8 supported by two sprockets 9 and 10 loose on xed vertical gudgeons 11 and 12.
  • Sprocket 10 is in one with a gear wheel 13 which meshes with another gear wheel 14 keyed on the shaft 15 of a pulley 16 connected by means of a belt 17 with another pulley 18 loose'- on a vertical driving shaft 19 rotated by an appropriate electric motor, not illustrated, which also drives the revolving knife disc not shown.
  • a clutch member 20 is slidably keyed on shaft 19, the said member being formed with lateral teeth adapted to engage corresponding teeth provided on the upper end of the hub of pulley 18.
  • sprocket 10 is rotated and transverse member 3 is reciprocated along. rods 4* togethe11with arm 2 and with the carriage supportedn thereby.
  • the normal position of stoppage is the Patented Mar. 31, 195g' XIIIT- position illustrated in Figs. 1 to 3, the carriage being at the end of its rearward stroke with respect to the revolving knife disc.
  • a casing 24 which rotatably supports a horizontal transverse shaft 25 carrying a ratchet wheel 26 at its outer end adjacent to member 3.
  • Wheel 26 has twelve teeth plus a blank space having the length of one tooth. In other words wheel 26 may be considered as a thirteen tooth wheel wherein one tooth has been suppressed.
  • Shaft 25 is connected by a pair of equal bevel gears 27 with a small longitudinal shaft 28 which protrudes from casing 24 towards the adjacent end side of base 1.
  • Shaft 28 is in turn connected by a universal joint 29 with an oblique shaft 30 which is passed through the wall of base 1, and on the outer end of this shaft there is keyed a wheel or disc 31 having a row of thirteen holes disposed along its periphery as the dial wheel of an automatic telephone apparatus.
  • the outer surface of base 1 under wheel 31 is formed as a lixed dial and bears twelve successive numbers followed by letter C, as shown in Figs. 4, Sand 10.
  • Shaft 28 is rotatable in a tubular shaft 32 which is itself supported by a bearing 1a fixed to base 1.
  • the outer end of shaft 32 is in one with a liat arm 33 which is bent twice at 90 to form in front of wheel 31 an abutment 33a (Figs.
  • the inner end of shaft 32 carries a cam 34 adapted to actuate a pusher switch 35 inserted on the circuit of the driving motor of the machine.
  • the arrangement is such that this circuit is closed when switch 35 is pushed (position of Fig. and that it is open when switch 35 is free (position of Fig. 4).
  • Wheel 31 carries a small pin 36 (Figs. 4, 5 and 10) which may act on the extension 33a of arm 33 for actuating the said arm at the end of the return movement of wheel 41, as explained below.
  • the movable transverse member 3 has a lateral downwardly directed arm 37 which carries a pawl 38 adapted to cooperate with ratchet wheel 26.
  • pawl 38 is in the form of a small two-armed lever pivoted at 39 and carrying at one of its ends a horizontal lateral iinger 40 adapted to engage the successive teeth of wheel ⁇ 26.
  • the other end of pawl 38 is loaded by a spring indicated at 41 in Fig. 6 and it also carries a horizontal lateral linger 42 (Figs. 2 and 3) adapted to cooperate with a gudgeon 43 (Figs. 1, 2 and 3) provided on the upper side of casing 24.
  • An abutment 33 is provided on the side of -arm 37 to limit the angular movement of pawl 38 under the action of spring 41.
  • the operator engages his foreinger in the hole situated in front of number 5 on the iixed dial and he rotates the dial wheel 31 clockwise until his forefnger has met extension 33a and has moved arm 33.
  • This angular displacement of arm 33 causes cam 34 to push pusher 35a and to actuate switch 35 whereby the electric driving motor is started.
  • pusher 35a limits the angular movement of arm 33 and stops the rotation of dial wheel 31. The operator then removes his linger from the latter.
  • the carriage is reciprocated and at each forward stroke thereof a slice is cut from the meat or other article supported by the said carriage.
  • the lower linger 40 of pawl 38 meets a tooth of wheel 26 (Fig. 7) and rotates the said wheel anticlockwise.
  • the upper finger 42 meets gudgeon 43 (Fig. 8) which causes pawl 38 to rotate about its pivot 39 against the action of spring 41 and to become disengaged from wheel 26 (position of Fig. 9).
  • the carriage is just at the end of its rearward or return stroke when this disengagement is effected and the arrangement is such that the angular movement of wheel 26 under the action of pawl 38 corresponds to one tooth of the said wheel.
  • Still another condition for proper operation of the device described is that the lower finger 40 of pawl 38 should not meet the mutilated portion 26a of ratchet wheel 26, i.e. the zone corresponding to the suppressed thirteenth tooth of this wheel. This is obtained by so timing ratchet wheel 26 with respect to dial wheel 31 that the said zone 26a is exactly in front of the last tooth actuated by finger 40 during the return or zeroizing movement of the counter device, i.e. the tooth which determines stoppage of the machine. l
  • the counter comprises a graduated knob 45 adapted to play the same role as the dial wheel 31 of Figs. l to 3.
  • Knob 45 is carried by a longitudinal shaft 46 which projects into the above-described casing 24 and which is connected by the bevel gears 27 with the transverse shaft 25 of the ratchet wheel 26.
  • the general arrangement of the carriage and of its driving gearing is quite the same as in Figs. 1 to 3, but the control mechanism of the clutch is quite dilerent.
  • the actuating fork 21 of the movable clutch member 20 is in one with an arm 47 (Figs. l2 and 14) connected by a link 48 with an arm 49 keyed on a transverse shaft 50 rotatably carried by bearings such as 51 secured to base 1.
  • a sleeve 52 On the end of shaft 50 opposed to arm 49 there is slidably keyed a sleeve 52 on the periphery of which? asva'srfi thenais provided ia longitudinally elagated 199th .5.24 which is bevelled, as indicated at 52b, at itsendreniote from the adjacent end of shaft 50.
  • Tooth 52 is adapted for cooperation with a small lever 53a associated lwith a micro-switch 53 inserted on the electric circuit of the driving motor of the machine.
  • Sleeve 52 extends beyond the end of shaft 50 in the form of a forkedfmember 54 substantially disposed in the vertical plane of shaft 50.
  • Member 54 embraces a cam 55 carried by a longitudinal shaft 56.
  • Shaft 56l also carries a second cam 57v which cooperates with a lateral lug 54a in onewith forked member 54.
  • -Lug 54a is provided with an vupperxtoot-h 54b adapted to be actuated by the carriage driving chain 8, as it will be explained below.
  • Shaft -56 is rotatably carried bybase 1 and its outer end has an actuating lknob 58 (Figs. 1 1vand 12).
  • Y i Y' For a given angular position of knob 58 cam 57 leaves lug 54a free to sink under the action of the driving chain, which causes ⁇ cle-clutchingof clutch member ⁇ 20 and stoppage of the carriage.
  • Cam 57 is then at such a position that Sleeve 5.2,A istat :its .foremost nesitieafgashatt 50, the end roller of lever 53a then being on the bevelled end 52b of tooth 52a; Switch 53 is thus open and the driving motor is at standstill.

  • ⁇ 'Ifn'owknob w58 is rotated through1 90 in a clockwise direction'from the position of Fig.1 15 ⁇ ,1scam 55- moves sleeve 52 on shaft 50 through about one'half of its full permissible stroke thereon, while cam 57 leaves lug 54a at the lowered position.
  • the bevelled end 52b of tooth 52a actuates switch 53 (position of Fig. 16) and the electric motor is started. But since fork 21 remains at the de-clutched position, the carriage of the machine remains at rest and the knife disc revolves ineffectively.
  • cam 57 raises lug 54a, thus causing rotation of shaft 50 whereby fork 21 is lowered and engages clutch member 20 with pulley 18.
  • Cam 55 pushes sleeve 52 somewhat further towards the rear of the machine (position of Fig. 17), switch 53 remaining at the closed position. The carriage is thus reciprocated and normal operation of the machine takes place.
  • knob 58 When knob 58 is rotated through a third angle of 90, cam 55 returns sleeve 52 to its foremost position, and cam 57 leaves lug 54a free to sink. But the arrangement is such that shaft 50 is frictionally retained in position whereby lug 54a is prevented to rotate under action of its own weight. The parts thus assume the position illustrated in Fig. 18. The end roller of the actuating lever 53a of switch 53 is on the bevelled end 52b of tooth 52a, but switch 53 nevertheless remains at the closed position. Operation of the machine thus continues as if knob 58 had not been actuated.
  • the first quarter of a turn of knob 58 starts the electric motor without starting the carriage, that the second quarter of a turn starts the carriage and that the third quarter of a turn causes automatic stoppage of the machine by action of gudgeon 59 on tooth 54b.

  • the operator When it is desired to cut a given number of slices, the operator first sets knob 45 to the corresponding position. Then he starts the machine by placing knob 58 to the position of Fig'. 17.
  • the ratchet wheel 26 is actuated at each return stroke of they carriage and when the said wheel reaches its zero position it drives sector 61 which through pinion 60 brings the parts to the position of Fig. 18. The machine is immediately stopped.
