摘要： Disclosed is a mechanism for shifting the rack of a selection mechanism for a single element printer from one position to another in timed relationship to the translation of a barrel cam which provides the necessary mechanical input to control the amount of rotation of the typehead. The control of the rack shift mechanism is a cam arrangement operated in timed relationship with the translating barrel cam to provide for the shifting of the rack at the beginning of each print cycle, if necessary, and the retaining of the rack in its shifted position at the completion of the cycle, thereby eliminating the necessity to provide for the time required to shift the rack back to its home position at the end of the cycle. The elimination of the restore operation of the rack provides more time during the cycle to operate the selection mechanism and accomplish printing or conversely provides for a smaller amount of time being required for the necessary functions thereby providing the capability of operating the remainder of the mechanism at a faster rate.

摘要： A print mechanism is described which has a constant current driven solenoid acting against an arch-shaped hammer to power the hammer through an arc of powered flight followed by an arc of free flight. The solenoid/hammer engagement point removes the solenoid to a position which does not obstruct print line visibility and the hammer rest position is withdrawn to improve print line visibility.

摘要： In a typewriter, a ribbon is contained within a cartridge which is in turn placed upon the ribbon mechanism support of the typewriter. The cartridge is maintained rigidly clamped to the support but readily releasable by means of operator actuation of a release lever. The cartridge may either be a single cartridge or may be stacked such as where two cartridges are utilized together, one containing a print ribbon, the other containing, for example, a correction ribbon. The cartridge containing the print ribbon is provided with a bottom plate or surface which is formed to define an aperture therein for the admission of a clamping member attached to the support. The clamping member is inserted into the aperture and then caused to rotate about its axis a part turn at which point the clamping member engages an inclined surface on the interior of the cartridge causing the cartridge to be wedged downward against the support. In so wedging, the hold down mechanism is capable of retaining the cartridge in a fixed position to oscillate with the support.

摘要： The blower is made separate from the rest of a self-ventilated range and is installed prior to the installation of the range. The blower can be selectively mounted for through-the-wall or through-the-floor discharge and is located so that the hole in the wall or floor misses the studs or joists, respectively. After the blower is installed, the self-ventilated range is set in place over the blower and the blower is connected to the plenum by means of a flexible pipe. In this way the plenum can be made thinner providing more room for the oven cavity.

摘要： A typewriter correction tape cartridge for holding and feeding correction tape for a correcting typewriter is improved by the addition of a beam spring cantilever supported such that one end of the beam spring wipes the correction tape onto the takeup spool. This will act to eliminate bubbles, wrinkles and crimps in the tape as it is placed in a new convolution on the spool and will thus reduce the outside diameter of the ultimate disc of used tape. The advantage of this spring is that a reduced size cartridge may be used while utilizing the entire volume of tape supplied on the supply side of the cartridge and, secondly, a more reliable takeup is accomplished due to the elimination of irregularities in the takeup disc. Where space considerations dictate that the spring be bent back sufficiently to accommodate a full spool without contacting the disc of ribbon accumulated on the takeup spool, the cross section of the spring, at a point near the anchor point, may be reduced by notching to provide a stress concentrated flex point and allow the spring member to still perform its function without premature engagement with the disc at a point other than at the wiper end.

摘要： Disclosed is a proximity ventilated cooking range adapted for countertop installation in a conventional stack-on kitchen cabinet. The surface heating units and ventilating air intake rest over a cut-out portion of the cabinet countertop with a ventilating air plenum and motor driven fan depending from the top surface of the range and disposed in the underlying cabinet. A housing enclosing an electronic air filtering unit is mounted closely adjacent the ventilating air plenum with a duct connecting the discharge of the fan and the interior of the filter unit housing. After moving through the filter unit, the air exits from the housing through a discharge opening at the front of the cabinet into the kitchen environs.

摘要： In a typewriter ribbon cartridge, it is necessary to maintain tension on the span of ribbon extending outside the cartridge to prevent tangling and to insure high print quality during machine operation. One technique for insuring that adequate tension is maintained is disclosed herein as an anti-backup back check device. Connected to the takeup spool of the ribbon cartridge is a disc member supporting thereon a pair of thin flexible resilient arms with outwardly oriented pointed ends. These ends formed in the shape of points engage ratchet teeth formed around the interior surface of a cylinder. The cylinder is formed as a part of the ribbon cartridge and, thus, is permanently positioned and fixed with respect to it. As the takeup spool disc and arms are rotated by the ribbon feed mechanism, the arms will flex and permit a rotation of the disc and takeup spool with a minimal drag force. Upon reversal, the points on the ends of the arms engage the ratchet teeth and the arms become compression columns resisting the rotation of the disc and spool. The center of the disc and the takeup spool are free floating within reasonable physical constraints. The teeth of the arms are positioned such that they are one-half tooth pitch out of phase to insure that one tooth is always in engagement with a tip of one of the two pawls.
