Abstract: The invention relates to a slicing machine (1) for cutting food slices by means of a carriage (2) that can be moved back and forth and a rotating cutting blade (11), wherein the slice thickness can be adjusted by means of a stop plate (12). For cleaning purposes, the carriage (2) can be emptied by tipping the carriage. In order to reduce the risk of injury during cleaning work, a blocking device is provided, which allows the carriage to be emptied by tipping the carriage only in a certain position and while the stop plate is blocked. Said safety feature is provided by means of a blocking slide (41), on which two mechanical safety precaution elements act independently.

Abstract: A multipurpose blind cutting machine is constructed to include a machine base, a first cutter unit and a second cutter unit mounted on the machine base and stacked with each other. The first cutter unit has a circular cutting blade and a cutter drive adapted to rotate the blade and to move the blade in a direction substantially perpendicular to the feeding direction of a blank blind to be cut. The second cutter unit has a locating molds having a plurality of positioning through holes for the positioning of parts of the blank blind to be cut, a cutting-off tool, and a cutter drive adapted to move the cutting-off tool in a direction substantially perpendicular to the feeding direction of the blank blind. A control unit is adapted to selectively control the operation of the first cutter unit and the second cutter unit.

Abstract: This invention is primarily a device to help prevent inadvertent carriage travel while using a radial arm saw and to facilitate feed speed control of the saw carriage, allowing operators with limited experience to use the saw with greater confidence.

Abstract: A rotary slicer 20 for comestible products. A stationary magazine 26 supports a product upright as a rotary table 38 carries a rotary knife 40 in an orbit that passes beneath the magazine. A freely rotatable center plate 80 of the blade facilitates movement of the blade through the product. Orbiting movement of the blade is automatically stopped with the blade remote from the magazine and electrical interlocks 109, 112 prevent operation without all protective safety covers 24, 102, 106 in place. A removable sharpener 172 is attachable to the top of table and operates with the blade flush with the table top. A product follower 118 within the magazine holds the product in place and urges it downward during slicing. The follower in part extends outward between the magazine 26 and magazine cover 106 to allow manual movement and release from a latched raised position, after the magazine cover is closed.

Abstract: A slicing machine for slicing food products, particularly meat and other meat products 7 comprises a rotating blade 1 which either has a spiral cutting edge or a circular cutting edge and is mounted for planetary motion, and a pushing mechanism 8, 9, 11, 12 to feed the product towards the blade 1 so that upon each rotation or gyration of the blade a slice is cut from the face of the product 7. The slicing machine also includes a cam and proximity switch 34, 35 for monitoring the position of the blade 1 and outputting a signal when the blade is in a predetermined position, an event counter 19 for establishing when the blade 1 is cutting the slice to form the last slice in a group of slices and outputting a signal indicating this condition, a manually operated interrupt switch 27, and a computer 18 to interrupt the feed of the product to be sliced towards the blade 1 of the slicer.

Abstract: A hand guard for a table mounted cutting tool. The guard includes a grooved underside adapted to rest on top of the work, and further includes a vertically movable heel for engaging the edge of the work to be advanced past the cutting tool.

Abstract: A shut-off device (104) controlling the operation of the motive means such as an electric motor which powers a tool such as a chain saw (12) having a housing (14) with a brake (34) therein operative to stop the chain saw (12). The shut-off device (104) includes a switch (54) biased off and shiftable on. A pivotable or shiftable trigger (72) is shifted toward but remains out of contact with the switch (54). A link (92) is caused to shift responsive to the brake (34) when the brake becomes operative, but the link is otherwise disposed intermediate the switch (54) and the trigger (72) to permit the trigger (72) movement to actuate the switch (54). However, on brake actuation the link is removed from a path of motion between the switch (54) and trigger (72) thereby to restore the switch (54) to "off" position. Once the link (92) is removed from the path of motion it cannot be reinserted therein until after the trigger (72) is released.

Abstract: A brake apparatus is disclosed for a motor driven saw blade, and includes a hub threadably attached at one end along its centerline axis to a drive motor, and attached to a saw blade via a flange formed on the other end of said hub, said hub having the shape of a cylinder. Also included are two brake shoes, one situated on each side of the hub, with each shoe including a brake pad portion thereon, such that when said brake shoes are actuated by brake actuation means operatively connected to said brake shoes, said shoes are caused to squeeze together to thereby brake rotative movement of said hub and therewith said saw blade. Means are also provided for adjusting the extent of brake shoe displacement during actuation as needed due to brake pad wear.

Abstract: A guard barrier in front of the exposed portion of the blade of a band saw is raised or lowered responsive to the elevation of the portion of the non-planar workpiece which is approaching the blade to be cut so that the varying length of exposed blade is continuously guarded without interfering with the cutting operation. A pneumatic cylinder controls the position of the guard barrier. Cam followers at the bottom end of the barrier ride along the uneven surface of the workpiece acting as a cam and follower movements operate a throttle valve which controls the pressure in the pneumatic cylinder to cause the barrier to move to and hover at its guarding location. An auxiliary valve is provided for rapid raising of the barrier to accommodate a steep rise on the workpiece, to broaden the range of useful operation in relation to workpiece profiles, and for manually controlled lifting of the guard.An electric system is coordinated with the pneumatic system to provide control and safety features.

Abstract: A press control includes a pair of pushbuttons each operating a pneumatic pump means to form a pair of signal pulses and an integrated valve to form a pair of binary logic pressure signals. A press position sensor provides a binary pressure signal related to the press position. The pushbutton and sensor signals are connected to fluidic logic gate means to compare and detect the actuation of the pushbuttons as well as the status of such pushbuttons and the press cycle. The logic output is connected by a plurality of logic gates to actuate a flip-flop output unit to generate an extend output or a retract output. The flip-flop output unit has an input connected to a latch input control to provide automatic reset to the retract output if release of the button signal sources occurs during a hazardous portion of the extend cycle. Once the non-hazardous portion of the extend cycle is reached, the latch is complete for the terminal portion of the extend cycle.
