A sheet deflector drive for driving a sheet-delivering deflector between a plurality of vertically stacked paper-receiving shelves, including a pair of deflector carrying belts for moving the deflector between the shelves; a rotatable drive shaft for driving the belts to move the deflector, rotation of the shaft in one direction moving the deflector upward and rotation of the shaft in the other direction moving the deflector downward; a bidirectional drive motor selectively engageable with the shaft for rotating the shaft to one or the other rotational direction; a cam connected to the shaft for rotation therewith and having three radially projecting lobes, the lobes having an angular spacing therebetween corresponding to the rotational movement of the shaft necessary to move the deflector from a sheet-delivering position adjacent to one of the shelves to such a position adjacent to an immediately neighboring one of the shelves; a pivoted cam follower arm biased toward the cam for engaging the lobes, the follow arm rotating the shaft upon disengagement of the motor to bring the follow arm into simultaneous engagement with two of the lobes, the cam and follower arm being aligned with the shaft to position the deflector in a sheet delivery position adjacent to one of the shelves when the follower arm engages the two lobes; and a selectively operable brake having an engagement member for moving into frictional contact with a free end of the follower arm when the brake is applied, the brake holding the engagement member in frictional contact with the free end with a force permitting movement of the follower arm away from the cam under the influence of the lobes, but sufficient to hold the follower arm at substantially the farthest distance the lobes move the follower arm from the cam. The release of the brake moves the engagement member substantially out of frictional contact with the free end to permit the biasing of the follower arm to move the arm toward the cam and to engagement therewith for positioning of the deflector.

An improved collator uses a novel sliding deflector assembly to allow greater spacing between the sheet conveyor 13 and trays 23. It also uses a novel sheet retention system which winds or unwinds as the sliding deflector assembly moves. The sliding deflector assembly may be driven with a double-clutch drive in increments in either direction. An improved plenum of the vacuum sheet-conveying system of the collator has a novel hole-spacing series to reduce noise and power demands for the vacuum system.

An improved sheet jogging apparatus allows for easier access and quicker maintenance by placing the primary components of the apparatus above the top panel of the bin unit of a collator/sorter. Quicker adjustment of the sheet jogging apparatus to accommodate different sizes and widths of paper is easily accomplished with a sliding shaft-slot-and-set screw means. Placing the components of the jogger on top of the panel alleviates problems of assembly where the limited space between the shelves of the bin unit and the top panel make work difficult and alleviates the problem of maintenance where the shelves must be removed for access to the components of the standard sheet jogging apparatus. A source of reciprocal motion mounted on top of the panel is connected to jogging bars which extend downwardly from the panel beside the shelves and which are capable of movement responsive to the source of reciprocal motion to jog the side edges of stacks of sheets on the shelves into alignment. A microswitch operatively associated with the jogging mechanism counts the number of jogging cycles through which the jogging bars move. A microprocessor responsive to the microswitch stops the source of reciprocal motion after a predetermined number of cycles.

A microfiche feeder 10 conveys isolated sheets of microfiche from a stack 30 to a collator 12, sorter, or other processing apparatus. The stack of microfiche is placed in a receiver. A drive wheel 34 contacts the lowest sheet of the stack 30 to increment the sheet forward by suction as the wheel revolves. Spaced separator rolls 44 and 46 adjacent the drive wheel 34 ensure that a single sheet of microfiche is incremented forward to drive rolls 52 and 54, which convey the sheet to other processing apparatus.

A sheet feeder with a feed wheel assembly for conveying an end sheet from a stack of sheets. The feed wheel assembly has a rotatable engagement wheel positioned to contact the end sheet of the stack, and operable to separate and convey the end sheet from the stack; a horizontally extending first shaft on which the wheel is mounted, with the first shaft being angularly movable in a generally vertical direction; a horizontally extending second shaft positioned spaced apart from the first shaft, the second shaft being mounted in a substantially fixed planar orientation to a support frame; and a pair of laterally spaced-apart first and second arms extending between the first and second shafts. Each of the first and second arms has a first portion retaining the first shaft and a second portion longitudinally spaced from the first portion and pivotally connected to the second shaft. The first and second arms are independently-pivotally movable about the second shaft within at least a limited range to permit uninhibited angular movement of the first shaft in a generally vertical direction during operation.

An improved drive system for a tandem collator obviates the need for multiple motors to drive the various components of the several modules. In a simple manner, the drive train of this invention achieves greater electrical efficiency with reduced maintenance by using a direct current motor to drive a shaft which extends into the primary bin of the primary module and which has coupling means to extend through the primary module into secondary modules attached in tandem. Power takeoff means associated with the line drive shaft power the various elements of each bin, particularly the deflector assembly. A preferred power takeoff includes a plurality of idler and drive sprockets associated with the drive shaft, a driven shaft which is transverse to the drive shaft, and a three-dimensional endless belt which runs between and around the various sprockets.

Submergible pumping apparatus for use in an oil or other well comprises, in a self-contained downhole unit, a double-acting reciprocating positive displacement pump for pumping well fluid, a reservoir containing power fluid for operating the double-acting pump, a rotary motor-driven positive displacement pump for supplying power fluid under pressure from the reservoir to operate the reciprocating pump, and a control valve for properly directing high pressure power fluid from the rotary pump to the reciprocating pump and from the reciprocating pump back to the reservoir so as to provide stroke reversal of the reciprocating pump.

A bit and sleeve have matching tapers and are pressed together so that in a working configuration the external diameter of the sleeve is stretched to slightly exceed the diameter of the bore into which the combined assembly is to be asserted. The sleeve is then partially removed from the bit to relax its external diameter so that the combined assembly can be placed into the bore. The bit and sleeve are then pressed into the working configuration in the bore until the sleeve has expanded radially into tight contact with the inner wall of the bore and the bit has seated itself on the end wall of the bore.A bit and sleeve assembly are pressed together and have matching surfaces which cause the exterior dimension of the sleeve to exceed that of the bore into which the assembly is to be inserted when the bit and sleeve are combined together in a working configuration. The sleeve and bit matched surfaces, however, are dimensioned to allow the external dimension of the sleeve to shrink to a dimension less than the inner dimension of the bore when the sleeve is partially removed from the bit.
摘要:
A conversion kit to adapt a single-feed continuous form paper press to dual-feed continuous form paper operation and thereby double production capacity. The kit includes infeed and outfeed bars which are attachable by their ends to corresponding pairs of drive pins of the infeed and outfeed tractors. Each of the bars is provided with a centrally located drive pin to project through overlapping perforated edge portions of both of the continuous form papers being printed. Infeed and outfeed support arms are provided which support infeed and outfeed guides. The guides are movable into and out of position over the centrally located drive pins of the infeed and outfeed bars to maintain the overlapping perforated edge portions of the papers entrained on the centrally located drive pins. The infeed and outfeed bars are provided with an aperture in each end portion which receives a corresponding one of the tractor drive pins, and a lock member is attached to each of the bar end portions to clamp the bar ends to the endless belt of the corresponding tractor. A supplemental paper collection tray is included to be positioned rearward of the main tray to permit the overlapping perforated edge portions to separate. A guide guides the rightmost continuous form paper to the supplemental tray.
