The paper exhaust detector of the paper feed tractor includes a microswitch with an upwardly biased plunger, and an actuator pressed upwardly by the plunger and pivotable between a first position in which it detects the presence of paper and a second position in which it detects the absence of paper. The cover of the present invention includes a plate, and elongated ribs projecting downwardly from the bottom surface of the plate on opposing sides of an elongated slot formed through the plate.

Abstract: A reel spring for use in a magnetic tape cassette has an elongated central base portion and adjoining end portions extending out of the plane of the base. The spring has first and second parallel side edges and terminates at transversely extending tip edges. The tip edges are joined to the side edges by cutout edges such that the width of each tip edge is less than that of the overall spring. The method for making the reel spring includes the steps of feeding a continuous strip of spring material into a shaping die for cutting and forming the strip into a finished spring. An end portion of the continuous strip material is severed from the continuous strip to form an individual spring blank. This is done by removing a pair of facing cutouts from the side edges of the strip at the appropriate location and slitting the strip in the area of the two cutouts. The blank is then formed into a finished spring.

Abstract: An apparatus of the type for the supply of webs to a processing station is described, in which by means of a controllable drive mechanism, each of several webs is advanced to the processing station in superimposed guide channels. The front portion of the web, following processing, is cut from the web and the front end of the web, following separation, is retracted out of the processing station. For this purpose, the controllable drive mechanism can be selectively engaged with one web in the vicinity of the guide channel of the web for the complete forward and return transport of the web before and after a processing operation. The drive mechanism preferably has reversibly drivable rollers. For producing an engagement between a web and a drive roller the guide channels are preferably pivotable with respect to the rollers. The processing station is generally a printing means, in which, for example tickets of differing color are to be printed.

Abstract: A system for passing long fan-folded documents and corresponding copy paper through a reproducing apparatus and including a collapsible, upright stand which carries a pair of copy paper roll supporting elements, a pair of paper guide plates pivotally and detachably connected to the top of the stand, and a guide bar for guiding copy paper from a roll on the stand to the guide plates. The system further includes an improved, two-part feed tray detachably mounted on the reproducing apparatus. Each part is selectively positionable on the reproducing apparatus to facilitate containment of a fan-folded document to be reproduced. Each feed tray part includes a base plate having a downwardly extending strap to locate the tray on the reproducing machine, and at least one upwardly projecting stop rib spaced from a paper discharge slot at the front side of each tray part, and acting as an indexing abutment for contacting and positioning the fan-folded document in the tray.

Abstract: A perforated paper feed mechanism such as a tractor has an optical system for detecting the presence of the form and particularly the motion of the form and utilizes a reflector which may be mounted on the lid of the tractor at one end of the tractor (where the paper enters or leaves the tractor). The optical system may be implemented by a prism which folds the path of light from a light source (an LED) to a photo detector (a photo-transistor) the path is aligned with the perforations in the paper. Since the perforations are spaced, the photo transistor provides a train of pulses as the paper is fed by the tractor. A pulse detector responds to the presence or absence of pulses within a given period of time comparable to the time when perforations are fed past the optical path. An output from the detector thus indicates whether the paper is in motion and is being fed by the tractor. Failure to receive pulses indicates either the absence of paper (paper out) or a jam in the feed.

Abstract: A webbing retainer plate retains an end portion of a length of belt webbing within a seat belt retractor spool. The spool includes a spindle and a hollow sleeve spaced outwardly of the spindle and rotatable with the spindle. An opening in the sleeve allows the end of a length of belt webbing to extend into the sleeve. The end of the belt is sewn in a loop and encloses a central portion of the webbing retainer plate. The central portion of the plate clamps the webbing loop against the sleeve and against the spindle, to block the belt end portion from being withdrawn from the sleeve. The webbing retainer plate has two arm portions which extend from the central portion. The plate arm portions engage the inner peripheral surface of the sleeve to maintain the plate in position lodged within the sleeve. The end portion of the belt webbing, including the sewn loop, is located within the outer peripheral surface of the sleeve. This allows the belt webbing to be wound smoothly on the exterior of the sleeve.

Abstract: A container for dispensing thin line, such as tippet material used for fishing, includes a housing having a flat end wall and a cylindrical peripheral wall which together define a cavity for holding several spools of the line. The lines pass from their respective spools through a slit in the peripheral wall. The slit has elastomeric liners along its edges, and these liners serve to grip the line, so that its ends are presented for gripping beyond the container. The housing also has a spindle which projects from the end wall of the housing through the spools, beyond which it has a screw thread. An end plate extends across the cavity where it opens out of the housing, this plate being attached to the housing at the screw threads on the spindle so that it can be turned down to clamp the spools between it and the end wall of this housing. This controls the resistance with which the spools will rotate when dispensing line.
