Abstract: Fluttering of caster wheels having a swivel mechanism including ball-type or roller-type bearings is effectively prevented by substituting, for some of the steel rolling elements of the bearings, resilient rubber-like rolling elements of somewhat greater diameter. Flutter resistance and steering characteristics of the caster can be varied by varying the size of the resilient rolling elements, or the proportion of resilient rolling elements to steel rolling elements in the bearing.

Abstract: A fluid dispenser and a support shoe are mounted to bear on opposite sides of a box blank passing therebetween. A normally closed valve of a nozzle of the dispenser has means yieldably biasing the nozzle to a normal position to intercept a leading edge of a box blank to open the valve upon deflection of the nozzle. A predetermined longitudinally spaced-apart gap relationship of the nozzle and support shoe effects return of the nozzle to normal position and closing of the valve, in response to the nozzle biasing means, concurrently with a trailing edge of the box blank leaving the support shoe, to wipe the closed nozzle clean on a deflected trailing end portion of the box blank. Alternatively, the support shoe may be rockably mounted for movement to a retracted position providing clearance for deflection of the trailing end portion of the box blank by the nozzle biasing means.

Abstract: A roller train in a carding machine comprises first, second and third card-clothed rollers, the second roller having two sets of teeth pointing in opposite directions, and the relative surface speeds of the rollers being such that one set of teeth on the second roller has point-to-point action with the teeth in the first roller and the other set of teeth on the second roller has point-to-point action with the teeth on the third roller.

Abstract: Apparatus for advancing slivers of textile or the like fibres through all stages of a combing operation in which a track is provided, in which track an endless element such as a chain is movable, the element providing an anchorage for a plurality of combing units adapted to carry the slivers, and the track including at least one linear section. The linear section of the track carries combing components so that the combing operations on the sliver are carried out substantially while the sliver is transported past the linear section of the track.

Abstract: Process is disclosed which is suitable for high speed production of uniform, lightweight webs by air-laydown of textile fibers. A toothed disperser roll doffs the fibers into an air stream of high uniform velocity and low turbulence to form a thin fiber layer from which the fibers are deposited in web form on a moving screen. A curved disperser plate, shrouds a portion of the disperser roll up to the point of fiber doffing. By using a disperser plate with a rough surface, preferably one having lateral grooves, web uniformity is remarkably improved.

Abstract: A door support bracket includes a slide member telescopically inserted in a housing bracket member. The housing bracket member is attached to a horizontal hung door by means of a swivel bracket. The free end of the slide member is pivotally attached to the frame for the door. The housing bracket member is formed from an elastic material and cooperates with cam members on the slide member to hold the door in an open position.

Abstract: Waste from a textile machine is removed by providing an air channel having top, side and bottom walls. In the area where the waste settles, the top wall of the air channel is formed by one or more shutters movable between closed and opened positions. When the shutters are opened, waste which has accumulated thereon when closed or which comes directly from the machine, falls into the air channel. The shutters are then closed and an air current is produced in the air channel by suitable means to convey the waste away.

Abstract: Apparatus for and method of pneumatically traversing a linear fibrous element during its packaging in a rotated perforated canister as air is withdrawn from the canister through its sidewalls and bottom wall; the air moves downwardly through the package during package formation to prevent freedom of movement to the element in the package and air moves generally horizontally as it is withdrawn uniformly from all sides of the canister through its perforated sidewalls to reduce air turbulence in the canister to promote ordered collection of the fibrous element.

Abstract: A spring compressing tool including a plate having three spaced holes therein. A center hole is provided to allow access to the locking nut of the caster assembly and two other holes in the plate are in alignment with two already available holes in the caster flange. Two elongated threaded studs extend through the aligned holes in the plate and flange elements with nuts engaging the threaded portions above the plate and below the flange holding the spring compressed and the outer and inner cylinders in a fixed relative position while the locking nut of the caster is removed. Loosening of the nuts on the elongated studs allows the outer cylinder to move upward causing the pressure on the caster spring to be relived gradually until the spring is fully expanded and can be safely removed. The spring is replaced in the caster assembly by reversing the procedure outlined.

Abstract: A device for use with a bearing construction for a swivel caster mountable on a caster mounting plate and including a yoke having a swivel plate pivotal about a pivot axis. A securing device is provided for securing the yoke to the caster mounting plate. The bearing construction is composed of a ball bearing retaining structure which normally abuts against the underside of the caster mounting plate. An elastomeric member is mounted between the bearing construction and the caster mounting plate. The elastomeric member has a compressible characteristic sufficient to maintain the caster firmly connected to the mounting plate while simultaneously being capable of yielding to a sufficiently large force applied to the yoke to permit a relative movement between the mounting plate and the yoke to thereby prevent permanent deformation to the yoke when an abnormally high force is applied thereto.

Abstract: Apparatus for blending, paralleling and cleaning fibers such as cotton and synthetics. The apparatus comprises a work roll having its surface covered with metallic wire and an arcuate, metallic wire section cooperating with a portion of the periphery of the work roll. The fiber is fed between the roll and arcuate surface, accomplishing the improved results noted in the accompanying specification.

Abstract: A method is provided for manufacturing a dimensionally stable compressed article such as an absorbent catamenial tampon comprising compressed cellulosic fibers. The method comprises the steps of first radially compressing a cylindrical blank to form a radially compressed blank having a length in excess of the desired finished length; then axially compressing the blank in a heated chamber to a length less than the desired finished length; then allowing the blank to expand to the desired finished length; and then maintaining the blank at this length while still in the heated chamber until the blank obtains the desired stability.

Abstract: A device for cleaning textile fiber flocks, comprising a conveyor band of a material that is penetrable by air, means for continuously feeding textile fiber flocks onto the upper run of the conveyor band and means for sucking air from below through the upper run when covered by a layer of the flocks, and a rotatable roller having elastically flexible leaves that protrude freely in radial directions and are substantially parallel to the axis of the roller, in proximity of the delivery end of the conveyor band and running in the same direction in which the upper band run moves, at such a high speed that the circumferential speed of the ends of the leaves is somewhat greater than that of the band, the roller being arranged in such a manner that the ends of the leaves strike, during their rotation, a point of the conveyor band that is not supported. A gap or interstice is provided between the roller and the conveyor band. The invention also provides optional, additional features for the cleaning device.

Abstract: An improvement in an apparatus for treating seeds or other particles with a liquid. The apparatus includes a receiving chamber for receiving particles and liquid, and means for conveying consecutive batches of particles and liquid to the receiving chamber. Liquid is metered in batches through a liquid metering means which includes a container and a cyclic container transport. The latter is responsive to the conveyance of batches of particles to the receiving chamber and cycles the container between a dip position in a supply of treating liquid and a dumping position in which a batch of liquid is conveyed to the receiving chamber. The transport orients the container in its dip position so as to drain the container when the level of treating liquid recedes below the container. The retention of treating liquid in the container when the apparatus is not in use is thus avoided.
