PATENT OFFICE.

The innovations relate to the replacement of the lever construction for the cutting movement the knife and the resulting change in the knife angle, on the simplification the friction inhibition, as well as the application and construction of the meat turner.

The attached drawings show:

Fig. 2 is a side view with a partial section,

The letters to designate the known parts are chosen in the same way as in Main patent, so that only the innovations are described in more detail below to need.

The complex lever mechanism by which the knives were given the rocking motion is here achieved by the direct connection of the slides m ¹ m ¹ with the knife holders 11 by means of the tie rods η η . The peculiar movement of the chopping knife does not allow the fixed pin connection between the heads of the tie rods η and the knife holders t \ are therefore ft fastened ¹ to the blade holders, in which the head spigot of the tie rods in respective sliders receive a rotating and sliding movement with slits provided connectors. These connecting pieces are attached to the knife holders 11 by means of wedges t "* 1 ² , which only need to be loosened if the knives P are to be dismantled for cleaning or grinding. This arrangement also makes it much easier to remove the knives.

By moving the points of application of the knife movement causing pull rods also the so-called blade angle of the main patent, are eliminated, and the segments are ί s with the rollers uu now only for lateral guidance of the blade against the rails ν ψ. The other peculiar knife guidance through the curved and straight slotted guide piece w, in which the pins attached to the middle knives and the segments ί ί are guided by means of the pin w ¹ , are retained from earlier. Likewise, the suspension of this guide piece on a sleeve y which can be displaced on the axis K and which is supported by the spiral spring ζ .

The friction inhibition of the wheels //, originally caused by an eccentric with a weight load, now consists of a curved, strong spring h, which is wedge-shaped into the groove of the wheels ff and allows the wheels to turn in only one sense.

The arms i ° i ° carrying the movement mechanisms for the meat turner QQ move with the frame J, but are also rotatably mounted around the central cylindrical part of the latter at i ¹ and P.

This rotary movement of the meat turner is conveyed by the waves α α; one sits on each of them through the action of one

Spiral spring s ¹ in spring and nut displaceable wheel /, which has only four teeth on one sixth of the circumference.

The after the vertical axis of rotation. The hub of this wheel facing the machine is provided with a groove in which the fork-shaped end of an arm of the angle lever r engages. The end of the other, the shorter arm rests on a leg of the right angle to the previous arranged and r ¹ supported angle lever ^r%, which slides with its tooth-like projection on the teeth of the crown wheel q and latches to require the relevant tooth gaps. The crown wheel q, which is fixed on the vertical shaft d of the worm wheel c driven by the worm /, is provided with four tooth gaps. If, for example, the worm wheel c now has 28 teeth, the tooth-like projection on the arm of the lever r ^{1 would} face the tooth gap of the crown wheel q with every seventh rotation of the shaft α. At this moment, through the action of the spiral spring s ^1, the tooth of the angle lever r ² latches into a tooth gap of the crown wheel q , while at the same time the four-toothed wheel / is shifted on the axis α until it enters the tooth segment P of the parallel to r ² mounted in double-P, equipped with weight loading lever L P enters for engagement.

The outermost end of the lever arm P is attached to the pull rod P by means of a universal joint, which communicates the jerky movement transmitted to the lever arm P by the gearwheel / by means of the tooth segment P to the support arm z '° of the meat turner Q. This jerky forward movement of the meat turner only takes place when the chopping knives are in a horizontal position. The meat turning means have completed their movement when the blades are on the extremest tip and then the mentioned mechanisms by means suddenly brought back into their former position by the lifted weight L of the lever P now comes into effect, and by the pull rod P the support arm z ° throws back together the meat turner associated with him. For pushing back the tetradentate wheel / and for tensioning the spring s ¹ is a b on the hub of the worm wheel of existing thumb b °, which, against the upwardly curved leg of the angle lever; - ² urgent, the tooth-like projection of the other arm from the tooth gap of the Crown wheel q , thereby simultaneously activating the angle lever r , which brings the wheel / into the previous position in an easily recognizable manner.

The shovel-like shaped meat turner Q touches the working surface of the block A1 with its receiving edge while it takes part in the slow rotating movement of the frame / . Below the shovel surface, two pivot pins are attached to each meat turner, which respectively in the adjustable guide rod m ^2. the lifting rod m ^{3 are} stored. The guide rod m ² is attached to the support arm z '° and mediates the previously described movements of the latter on the meat turner Q. The rotation in one sense is mediated by the segment P, lever arm P and the pull rod P ₁ the backward movement is initiated by the weight L attached to the tooth segment P.

The lifting rod m ^{z of} the meat turner is also connected to the support arm i "in such a way that a slot at the upper end of the lifting rod receives a pin attached to the support arm i ° , which allows the lifting rod m ³ to slide up and down, causing the meat turning Q to obtain a tilting movement. its upper end carries this lift rod nor p is a small roll, which imaginary in the earlier sudden rotation of the support arm i ° from the fixed to the carriage vP oblique run-on surface ο urged raised and consequently the tilting of the meat turning conveyed.

The meat turner works as follows:

With every quarter turn of the wheel q the tooth-like projection of the angle lever r ^{2 is} latched in the manner described in the corresponding gap of the wheel q; as a result, the wheel / is brought into engagement with the P segment. With further rotation of the shaft α , the support arm z '° with the meat turner is now caused to rotate about the axis K by approx. 90 ° by means of the segment P, lever P and the pull rod / *. The meat turner Q is filled with the meat located outside the respective work surface on the block until the roller fi hits the inclined contact surface 0 ; the lifting bar m ^s comes into action, which quickly overturns the meat turner Q. This rapid lifting is mediated in two ways: first, by sliding the roller p up onto the inclined surface 0, second, by the surface o, which is still rising with the carriage m , so that the meat tilts at great speed, causing it to stick to the meat turner Q is avoided. As soon as the meat turner is completely tipped over, the last tooth of the wheel / the segment / 'leaves, and the weight L mediates the falling back of the meat turner into its original position, while at the same time the tooth-like projection of the lever r ² - from the corresponding tooth gap of the crown wheel q excavates. This will keep the wheel out of engagement with the. Segment / ¹

brought until the same process is initiated again after rotating the shaft α seven times. The four teeth of the small wheel / must therefore be arranged in such a way that the last tooth leaves the segment at the moment when the corresponding slide m1 has reached its highest position, i.e. also the corresponding knife side has reached its highest position.
