Abstract: A textile card cleaning apparatus is provided which comprises a plurality of suction hoods disposed within the arcuate chamber defined by the continuous belt of flats disposed above the main cylinder of a textile card. The plurality of suction hoods is adapted so as to draw cotton dust and lint both from the arcuate chamber wherein they reside and up between the flats from the working space between the main cylinder of the textile card and the lower operative run of flats adjacent thereto. The cotton dust and lint is then drawn off to a remote location by suction means fluidly communicating with the plurality of suction hoods.
Abstract: An electrically lighted, vertically and laterally adjustable sight for an archery bow. The sight comprises an elongate battery housing for being mounted lengthwise on an archery bow. A pair of electrically conductive contact strips is carried by the battery housing on a dovetail flange, and at least one sight pin holder is mounted on the dovetail flange for selectively adjustable movement along the longitudinal extent of the contact strips. An elongate sight pin having a light emitter on one end is transversely slidably mounted on the sight pin holder and includes elongate electrical contact strips positioned thereon. A current conductor carried by the sight pin holder operatively interconnects the contact strips on the dovetail flange and on the sight pin.
Abstract: A mobile cleaning apparatus for removing dirt and debris from the surface of parking lots and the like characterized by the ability to quickly and efficiently remove debris from the surface to be cleaned and dump the collected debris into a remote upstanding trash bin. The mobile cleaning apparatus includes a mobile vehicle chassis and a pickup head for gathering the debris comprising a pair of forwardly swept, diverging arms including an air pressure port adjacent each opposing free end thereof and a suction port at the juncture of the arms so that dirt and debris dislodged by the air pressure ports tends to move toward the rearwardly positioned suction port. The mobile cleaning apparatus further includes a collection hopper which is movably mounted on the vehicle chassis having a positively actuated door in the bottom thereof and means for raising the collection hopper to a predetermined rearwardly raised position so that the door may be opened and collected debris dumped into a trash bin.
Abstract: A roller having a readily replaceable sleeve so as to allow replacement with a like sleeve and comprising a core with a suitable elastomer layer fixedly secured to the outer peripheral surface thereof and a removable sleeve adapted so as to longitudinally slide onto the core and frictionally engage the outer peripheral surface thereof so as to rotate with the core. The removable sleeve comprises a substantially rigid inner layer for engaging the peripheral outer surface of the elastomer layer of the core and an outer surface layer of a suitable elastomer fixedly secured to the inner layer. The outer surface layer of the core is compressed when engaged by the removable sleeve and imparts a compressive force to the inner surface area of the rigid inner layer thereof so as to maintain the core and the replaceable sleeve in concentric relationship to each other.
