Abstract: The invention relates to a coupling (110) for connecting a compressed air source to an air motor, comprising a housing (116) with a housing channel leading to a compressed air connection (118) and a piston (124) axially adjustable in the housing channel (122) and force-loaded by a spring element (126) having a piston channel (132) which, when the coupling is connected to the air motor, merges into a connecting channel (138) present in a pin element (140) of the air motor. The piston can be adjusted in the direction of the compressed air connection by means of the pin element against the force applied by the spring element. The spring element (126) runs between the compressed air connection (118) and the compressed air connection side area of the piston (124). Radial openings (34, 36, 134, 136), through which compressed air flows, extend from the compressed air connection side area of the piston channel (132).

Abstract: A quick release fastener for a hand-operated band saw with a saw band run on wheels in a housing, which has a base tray and a hinged lid and on which there is a handle. The handle is fixed to an upper angled edge of the lid and located below the handle there is a spring-loaded handle bar with two bent ends. The one end is fixed at the edge of the lid and the other end engages in a groove in the base tray through a recess in the edge.

Abstract: A slide block for a saw band in a bandsaw machine, which is disposed as a pair at a distance to one another and between said pair a slot is present, through which the saw band is guided, and the frictional forces of the running saw band are absorbed on the edges of the slide blocks, whereby the slide block is made of a hard ceramic.

Abstract: A quick release fastener is provided for a hand-operated band saw with a saw band run on wheels in a housing, which has a base tray and a hinged lid and on which there is a handle. The handle is fixed to an upper angled edge of the lid and located below the handle there is a spring-loaded handle bar with two bent ends.

Abstract: A handheld skinning device having a tooth roll, which is retained motor-driven in a housing with side arms and rotating about an axis, and having a blade which in an operating position is positioned with a gap parallel to the tooth roll and is retained in a blade mount, which is formed by side parts fixed to the side arms of the housing and a blade holder. The blade mount in the operating position is fixed in the side arms by releasable locking, and in an opened position of the blade mount the blade can be removed from the blade holder. The locking of the blade mount in the operating position occurs by two spring-loaded locking pins in the arms, which are releasable together via a disengaging plate and in the opened position the blade holder remains connected to the arms of the housing.

Abstract: A circular blade with stand for cutting and portioning animal products. The circular blade rotates about a rotational axis on a vertical cutting plane and the blade is driven by a drive motor. The device includes a horizontal working plane on which the product to be cut is supported and guided in a transverse manner in relation to the vertical cutting plane. The drive motor driving the circular blade uses an angular gear and is held in a fixed position on the stand above the circular blade so that a free working area is provided on both sides of the circular blade for the uninhibited handling of the product to be cut.

Abstract: A coupling has a safety lock and receives a flexible driveshaft with a tube into a hand-tool. The coupling contains a pinion as part of a drive transmission of the hand-tool and a lever on a handle. An opening of the pinion can be connected to an end of the driveshaft, and the lever engages into a retaining groove of the tube as long as the lever is gripped together with the handle. In a drive position, a direct positive engagement between the driveshaft and the pinion is produced, and the transmission is thus driven. The coupling contains a spring that pushes the driveshaft into a rearward rest position as soon as the lever on the handle is released, whereby the positive engagement between the driveshaft and the pinion is disengaged and the transmission is thus set to rest.

Abstract: A quick-change system for blades of a meat trimmer, which is used as a cutting tool in the stripping or cutting of meat and the like, includes a handle with a connecting housing to which a ring-like blade holder is attached. A ring-like blade is held inside the blade holder and rotated by a driving gear. The connecting housing has arm-like projections on both sides, on which the blade holder is mounted and has a separation point between the projections. The ring-like blade holder is fixed to a projection in an operating position by the head of a releasable bolt. When the bolt is loosened, the blade holder is bent open from an operating position to a blade change position in which the ring-like blade can be changed without tools in a very short time, without the necessity of readjusting the blade holder after its return to the operating position.

Abstract: The invention relates to a device for cutting and stripping meat (1), said device being used to divide up an animal product (28) to be cut. Said device comprises a cutting bench (2) that is mounted on a trestle (3) and a circular blade (6) that is mounted on said bench. A motor (10), which is equipped with a gear (11) that is attached to a flange, is connected to a rotating shaft (12) to produce the drive and is positioned above the rotating shaft (12) on one side on a pivoting arm (8), which is fixed to the trestle in a discharge zone (2A) behind the circular blade (6). Said pivoting arm is narrow (8), extends in approximate alignment with the circular blade (6) and is mounted on the trestle (3) by means of a pivoting articulation (19) that is fixed to the cutting bench (2). The pivoting actuator (29) of the pivoting arm (8) is a spindle drive (29), which is connected in an articulated manner to the pivoting arm (8).

Abstract: The invention relates to a device for severing a spare rib (RR) from a backbone (R), whereby the split backbone is conveyed inside a guideway (2), which is comprised of two guide plates (21, 22) and which delimits a wedge-shaped channel (23) through which the spare rib (R) projects each time and a cutting edge (10) of a cutting device (1) traverses past on the side of the rib. The cutting device (1) is a rotary blade with a cutting rim (10), which is tapered to form a sharp edge, and its cutting blade (11) is arranged nearly parallel to the guide plates (21, 22) whose distance from one another can be adjusted.
