Rotatable blade mechanism (20) is translatable in corresponding U-shaped slots between anchor stations. At a particular anchor station (A or B), a rotatable anchor arm (22 or 24) locks the pivoted fastening joint (38) of rotatable blade mechanism (20) into the relevant set of vertical legs of the corresponding U-shaped slots. With a hose inserted into one set of the corresponding support openings, the blade mechanism (20) may be rotated to cut the hose.
Abstract: A corrugated thin metal strip is advanced through a cut-off mechanism having a movable upper blade and a lower stationary blade. A curtain of air is directed downwardly against the tip of the corrugated strip to momentarily arrest its movement with a return bend between a pair of adjacent convolutions of the strip centered over the stationary blade. The upper blade descends and shears the strip transversely along a return bend.
Abstract: A pneumatically operated feeder for punch presses and the like and having a feed slide that is adapted to be moved automatically through successive feed and index strokes. Instead of using a limit switch type device for sensing for the physical presence of the feed slide when the latter has reached the end of an operative stroke thereof, an improved control means is provided to identify the completion of such an operative stroke and to thereby cause said feed slide automatically to initiate its next operative stroke. When pressure fluid is applied to the main fluid motor of the feeder in order to produce say an index stroke of the feed slide the effective fluid pressure in said motor will not normally reach line pressure until after completion of said index stroke.
Abstract: This device for causing elongated cylindrical objects such as cigarettes delivered in the form of a continuous line to penetrate successive recesses formed in a rotary drum is of the type wherein a transfer device is interposed for accelerating the velocity of translation of the cigarettes in order to separate them from one another while imparting thereto a transverse velocity equal to the peripheral velocity of the drum recesses; this transfer device comprises a single vertical cam of which the operative portion engages the cigarette moving past underneath, when the leading end of the cigarette penetrates into a corresponding recess of the drum. The combined action of the cam and drum cause the cigarette to move transversely and parallel to itself.
Abstract: An apparatus for punching of symbols into template material with a punching tool. The punching tool has punching pins selectable by corresponding selector means. An operating mechanism, after selection of the punching pins by the corresponding selector means presses the punching pins through the template material in a grid arrangement characteristic of each symbol to be punched into the template material. The punching tool has several parallel rows of punching pins, of different punch sizes for punching of symbols in different sizes of lettering and/or types of lettering. The selector means selects and operates the punching pins of only one punching row, in any desired combination for punching of symbols according to a straight-line dot grid.
Abstract: There is disclosed an apparatus for punching packages of paper money and other securities for defacing them, the apparatus preventing the sticking together of individual sheets of said packages in order to permit a subsequent mechanical counting of the punched sheets of the package.
Abstract: A machine for trimming the edges of metal containers in which a plurality of upstanding, vertically disposed cams are positioned upon a table. A plurality of sliding cutters are provided equal in number to the cams. The cams are driven up and down by a vertically reciprocating platen below the table by means of a power source, a crank shaft and an arm coupling the crank shaft and platen. Various cam face shapes and cam followers are disclosed to provide the cutting sequence of the cutters.
Abstract: Apparatus for cutting a running web of paper or the like has a rotary disk-shaped first knife and a driven counterknife. The first knife is rotatable on a shaft which constitutes the piston rod of a double-acting pneumatic cylinder and piston unit. The cylinder of such unit is connected with a second piston rod forming part of a single-acting cylinder and piston unit. The control system for the two units includes a shutoff valve which can admit compressed air to the single-acting unit whereby the pressure in a first conduit which connects the source of compressed air with the single-acting unit rises when the second piston rod reaches an end position in which the marginal portion of the first knife overlaps but is remote from the marginal portion of the counterknife. A second conduit thereupon admits compressed air to the double-acting unit in order to move the first knife axially against the counterknife.
Abstract: On a power saw of the type having a circular saw blade which is operatively moved against a stationary workpiece to perform a cross cutting action thereon, a lighting device is provided on the saw to cast the shadow of the blade edge on the workpiece ahead of the saw whereby the operator can manipulate the workpiece so that a mark or point thereon comes into aligned registration with an edge of the shadow.
Abstract: A card which a customer receives at the time of driving the vehicle into a parking lot and which bears encoded information denoting the date and time of entry is processed when the customer desires to remove the vehicle. At such time, the card is inserted into a housing to be automatically advanced in a first direction past a reader which decodes the information and supplies signals to a computer which actuates a perforating device serving to apply legible information to at least one portion of the card. The card is thereupon moved in the opposite direction into the range of a severing device which separates the one portion from the remaining portion of the card. The one portion is removed by the customer to serve as a customer receipt, and the remaining portion is transported away from the severing device and into a safe to serve as an operator's receipt. The legible information normally includes the cost of parking.
Abstract: Apparatus for cutting paper sheets wherein a first knife, which is freely rotatable on a shaft, is movable sideways toward and away from a driven counterknife. The shaft is reciprocable in a carrier which is connected with one end of a reciprocable and turnable piston rod. The piston rod extends into a cylinder and is reciprocable by a spring and a membrane-like piston. The orientation of the first knife with respect to the counterknife can be changed by turning the piston rod with reference to the cylinder so that the piston rod can assume and is held in any one of several angular positions. To this end, the piston rod is rigidly connected with a radially extending projection which is disposed between two rollers mounted in the cylinder for movement at right angles to their axes. One of the rollers is biased against one side of the projection by a helical spring, and the other roller is movable at right angles to its axis by an adjusting screw which meshes with the cylinder.
Abstract: A dispenser for cards which are withdrawn by customers at the entrance of a parking lot has a housing for a supply of coherent cards which are transported seriatim by advancing rolls toward an outlet opening for withdrawal by customers. On its way toward the outlet opening, each card is provided with legible information by a matrix printer which can apply such information in response to a signal from a computer while the card is in motion. The thus imprinted card then advances between the matrix and the perforating tool of a punching apparatus which applies one or more holes while the card is in motion. The matrix and the tool are mounted on a plate which is secured to a fixed bracket by a first parallel motion mechanism so that it can move in and counter to the direction of movement of the card between the tool and the martrix. The plate is pivotable about a fixed axis by an oscillating crank gear so that the tool moves along an arcuate path to which the adjacent card is tangential.
Abstract: A method and apparatus for acting on angle irons or the like. A vertical stack of angle irons is provided and the angle irons are fed one at a time to a punching position. At the punching position a hole of selected size is punched in the angle iron, and the angle iron is fed from the punching position in a linear direction of movement to a cutting position. The length of the angle iron to be cut is determined by measuring the length of angle iron in the direction of movement past the cutting position, and the angle iron is cut at the cutting position. Cutting is accomplished using a crankshaft with at least one cutting blade operatively connected to the crankshaft at a portion thereof offset from a line between the bushings, guide structures being provided for guiding the linear movement of the cutting blade. Each cut angle iron is removed from the cutting position in a direction normal to the linear direction of movement of the angle iron to the cutting position.

Abstract: An anti-skiving device used for beveling an edge of photographic film so that when the film is processed the emulsion or anti-halation backing on the base of the photographic film will not flake or skive. The device eliminates flaked or skived material from the edge of the film from being processed on the film itself, which heretofore caused an unsightly appearance on the processed film.
Abstract: Apparatus for subdividing a running paper web into sections of desired length has a first motor which drives the web at a constant speed and a D.C. motor which drives an orbiting knife at a speed which varies during each angular movement of the knife through 360 degrees. A detector which monitors the speed of the web transmits signals which are utilized to insure that the speed of the knife matches the speed of the web during that stage of each orbital movement when the knife cuts the web. The length of intervals between successive cutting operations is adjustable by connecting the knife with any one of several graduated disks whose graduations are monitored by a second detector which controls the speed of the knife during intervals between successive cutting operations.
Abstract: A cutter block for attachment to a rotatable drive shaft is composed of two semi-circular elements which are connected to one another and together form a torus. Each element has a cavity therein which is defined on the radially inner side of the element by a flexible membrane. To attach the block to the shaft, the block is slid over the shaft and the cavities are then pressurized to distort the flexible membrane. The cavities are connected to one another in gas-tight manner by a passage sealed by an O-joint.
