Abstract: In ground engaging tools, reliable fastening devices are needed to quickly and effectively secure replaceable earth working tips to adapters. The fastening pin assembly should be configured in such a way as to prevent pin loss or breakage which causes the tip to be lost and/or the adapter damaged. This invention consists of two pins and an interconnecting and retaining means. When assembled, each pin will extend approximately to the middle portion of the adapter through axially aligned bores defined in both the tip and adapter. The interconnecting and retaining means is located in the middle portion of the adapter between the two pins and retains the pins in the adapter bore. This invention protects against pin loss/and or breakage and is beneficial to all type of earth working replaceable tip applications.

The adjacently disposed type carriers (12) are connected together by connecting webs (28) adapted to be sheared off. In the method according to the invention for assembly the stamp printing mechanism using a type carrier set according to the invention in which the type carriers are endless bands, the type bands connected together are separated from each other consecutively in each case on turning for the first time of the setting shaft by shearing off the connecting webs (28).

Abstract: A printer includes a main body having an upper opening. A platen is arranged in the main body such that it opposes the opening. A cover is mounted on the main body such that it is pivotable between a closing position, for covering the opening except for a portion above the platen, and an opening position, for exposing the opening. A cutter having a blade is supported on the inner surface of the cover such that it opposes the main body. The cutter is pivotable between a stand-by position, where the blade is located above the platen, a cutting position, where the blade abuts against the peripheral surface of the platen, and a housing position, where the blade is located at a side opposite to the platen, about the pivotal center of the cutter. The cutter is selectively urged by springs toward the stand-by position or the housing position.

Abstract: A printer housing which can be adapted for both cut sheet printing paper and continuous printing paper without replacing any of its paper guide members with any external paper guide members. The printer housing comprises a first cover which is pivotably supported at its front end and a second cover which is povoted to the first cover at its middle part and can cover an opening in the upper face of the printer housing main body by complementing the first cover. When the second cover is thus covering the upper opening of the printer housing main body in cooperation with the first cover, the printer housing is adapted for continuous printing paper. When the second cover is brought to an oblique position, the second cover can serve as a guide for feeding cut sheet printing paper into the printer. The printer is preferably provided with a tractor feeder which can be thrown backward to be out of way for cut sheet printing paper and to support the second cover at its oblique position.

The drive means is operable to decelerate the printing cylinder and then to cause the printing cylinder to regain its normal operating speed so that the web overtakes the printing by a selected distance before the next printing nip is formed.

Abstract: A backhoe bucket especially adapted for use in rock strata such as caliche, limestone and soapstone and plastic soils includes a shovel-nose configuration having a plurality of spaced-apart teeth symmetrically arranged along upwardly and rearwardly inclined leading edges of the angled bucket sidewalls. The sidewalls of the bucket to which the teeth are attached intersect a flat, horizontal bottom having a width substantially equal to the width of the tooth mounted thereto. The teeth are arranged in a symmetrical stair-step configuration with each tooth being above and behind an adjacent tooth closer to the center of the bucket. The teeth first fracture, then separate and guide material into the bucket. The rear wall of the bucket is a complex, curved panel which defines an internal volume shaped to receive and readily discharge spoil.
