Abstract: A device for supplying webs of wrapping material to a cigarette making machine of the two rod type is constituted by a device for cutting a web of wrapping material into a first and a second web of identical width, and by deviation devices associated with each of the webs for the displacement thereof in a direction crosswise to that in which the webs move forward. Connected to the first and second web are detector devices provided for operating, through circuit elements, a motor for each of the three deviation devices in such a way as to cancel, moment by moment, any possible differences in width between the first web and the second web and any deflection thereof with respect to a given sliding position.

Abstract: An improved rotary cutting apparatus is provided for cutting vegetables, particularly such as potatoes, into a distribution of strip sizes not exceeding a predetermined length limit. The apparatus comprises a conventional rotary impeller having peripheral blades for carrying potatoes into cutting relation with a slicing knife on an impeller housing for dividing the potatoes into slices followed by subsequent cutting into strips by strips knives on an adjacent cross-cut spindle. The impeller further includes an axially centered divider ring defining a pair of annular chambers for potato passage outwardly to the slicing knife, wherein longer potatoes are required to orient with their longitudinal axes extending generally radially with respect to the impeller, and generally perpendicular to the slicing knife, to limit the maximum length of the cut slices and the resultant cut strips.

Abstract: Pneumatic impact hammer for driving a frost plug into an engine block. The hammer includes a port for interconnection to a supply of compressed air, a chamber, a trigger, an elongate tube, a mallet slidably mounted within the tube, and a driver extending from one end of the tube. Compressed air is received by the chamber. Upon depressing the trigger, the compressed air within the chamber is substantially instantaneously applied to the back of the mallet. Consequently, the mallet is driven down the length of the tube toward the driver. The mallet impacts against the driver which, in turn, drives the frost plug into the engine.

Abstract: A mechanical, infinitely variable blade speed drive for a band saw is provided with a speed control which includes a variable pitch drive pulley with axially adjustable sheave spacing to vary the drive ratio between the drive pulley and the driven pulley and a control shaft parallel to the drive shaft of the motor which carries the drive pulley. The control shaft extends to the front portion of the band saw so that the speed adjustment control carried thereon is readily accessible to the band saw operator without moving away from the front portion of the band saw during its operation.

Abstract: A hydraulic shearing machine for cutting steel sheets and the like in which the lower blade is fixed between two vertical end-plates of the frame while the upper blade is carried by a movable apron. The support provided for the lower cutting blade consists of a hollow box which extends horizontally between the vertical end-plates of the shearing-machine frame and only the ends of which are attached to the frame. The lower blade is fixed against one of the side walls of the support box so as to be displaced with respect to the theoretical center of rotation of said support box about its own axis. In consequence, the vertical forces exerted on the lower blade at the time of utilization of the shearing machine tend to produce a twisting movement of the support box, thus providing compensation for the horizontal flexural displacement of the box under the action of the horizontal forces.

Abstract: A kitchen or domestic food slicer having a flat bed surface over which the food is moved and a knife mounted essentially across that surface. The knife alone being pivotably mounted such that its sharp leading edge can be raised or lowered relative the bed surface to vary the thickness of cut. The pivoting of the knife is achieved by cam surfaces on a pair of bars one positioned either side of the bed surface, the bars being slidable lengthwise by a rotatable knob and the cam surfaces including inclined portions to cause pivoting of the knife as the bars slide longitudinally.

Abstract: Apparatus for cutting heavy wall tubing including vertical and horizontal mechanically driven rams operated in sequence to drive blades fully through a tubing section. Notching blades cut shallow notches in the section in advance of the main blade entries thereby to prevent dimpling.

Abstract: An improved tape dispenser/receptacle having complimentary oblong-shaped top and bottom portions adapted to mate with each other, wherein the improvement consists of: first and second spool-dispensing axes, each axes composed of ten pegs; longitudinally-oriented inner and outer sets of ridges, extending downward from underneath the device's top portion; a plurality of tape exist and flattening apertures; resilient tabs extending outward from the device's side walls, in one-to-one correspondence with the exit/flattening apertures; and a cutting surface. The spool-dispensing axes hold rolls of tape or other material which may be marked with identifying indicia. The inner ridges touch the radial surface of the tape rolls to keep the rolls from wobbling during dispensing, while the outer ridges act as means to keep the tape straight en route through the exit/flattening apertures.

Abstract: Apparatus for automatic coil feed of a sheet metal stock strip in progressive dies for punch press die operations which adjust the length of stock strip being intermittently fed to the punch press die while the press is operating. The apparatus comprises feed apparatus for feeding a predetermined length of stock strip to the punch press die which feed apparatus normally operates at a preset feed length. There is a control for maintaining the correct feed length of the stock strip being intermittently fed into the punch press die and includes a correction arrangement operable to mementarily change the preset feed length to supply a correcting length of stock strip to the punch press die. There are two longitudinal arrays of registration openings in the stock strip.

Abstract: Flexible, tubular and inflatable sausage casings are cleanly severed during continuous shirring operations without formation of troublesome loose tab-ends by impinging thin, high pressure, high velocity water jet(s) against casing sidewall. Severing may be performed over a shirring mandrel without damage to the same.
