Abstract: The invention relates to an assembly machine having a frame, an upper plate vertically displaceable, a table, an annular transfer plate, a cam-shaft and a driving device for said cam-shaft. Said machine comprises working units of three kinds, the one fixed onto the upper plate and the others fixed onto the table either inside or outside of the transfer plate. All working units fixed to the upper plate and the ones fixed to the table inside the transfer plate are controlled by cams carried by the cam-shaft and corresponding mechanical linkages passing through a control opening provided in the table of the frame.

Abstract: A paint roller cage assembly apparatus in which a group of four cage wires are held and affirmatively positioned generally as if at the corners of a square; a cage wire cap with sockets for the cage wires is then applied to one end of the cage wires, and a similar cage wire cap is next applied to the other end of the cage wires, thereby automatically assembling a paint roller cage; the apparatus includes cage wire feeders, and a plurality of cage wire holders in the form of pivotably associated links which may be pivoted to position the wires for the application of the caps.

Abstract: An apparatus for use in continuously assembling joinable ring shanks and ring settings into a corresponding unitary jewelry type ring comprising supporting means; advancing means operatively connected to the supporting means including at least one work holding means which removably receives a ring setting and ring shank for successively and incrementally advancing the work holding means, as well as ring shank and setting, from at least a loading station to a plurality of discrete working stations, including at least a ring shank testing station, and a bonding station, ring shank testing means located at the ring shank testing station for accurately testing for the presence and correct alignment of the ring shank with respect to the corresponding ring setting in the work holding means; and bonding means situated at the bonding station for selectively bonding the aligned jewelry ring.

Abstract: A rotary conveyor for moving work pieces mounted on a mandril through a plurality of work stations is provided where the manufacturing steps at each work station require different time intervals to carry out; to reduce the dwell time of the rotary table, the work tool requiring the longest dwell period is mounted directly on the table at each mandril position so as to be movable through all of the work stations with each work piece; a cam surface and cam follower arrangement are provided for moving the work tool into and out of the working position at selected work stations.

Abstract: An improved method and machine are described for automatically loading a scroll of interwound photographic film and backing paper into a film cartridge. The cartridges are opened for scroll insertion by an initial relative movement of the cartridge halves in one direction and by a further separating movement in a differing direction. The machine has a rotatably mounted turret supporting a number of separate loading heads each of which supports a film cartridge and performs a two direction cartridge opening and closing action. The turret carries the heads through a series of stations where successive head loading, cartridge opening, scroll insertion, scroll to spool attaching, cartridge sealing, torque testing and winding, marking, and head unloading operations are performed. The heads and stations are controlled in their operation by a combination of direct cam control and multi-channel programable logic system control.

Abstract: Casting ladle gate valves of the type which are designed to be installed and removed from the ladle as a unit, are rebuilt in a work area which includes a disassembly station, a first assembly line including a revolving table for renewing the movable slide parts and a second assembly line including a revolving table for renewing the slide housings, and reassembling the slide parts, slide housings and clamping lids into renewed gate valve units. By preference, the disassembly station, both revolving tables and a conveyor for carrying the units to the work area from the foundry or steel work, and back are served by a slewing crane.

Abstract: A base-supported rotatable frame assembly that defines four upwardly and inwardly extending side frames. A pressurized fluid-actuated mechanism intermittently rotates the frame assembly through first, second, third and fourth stations. Stringers are removably placed in fixed positions on a side frame when it is at the first station, and deck boards are placed in abutting contact with the stringers when the stringer-supporting side frame is at the second station. The deck boards and stringers are nailed together at the third station to provide a single face pallet, which pallet is removed when the supporting side frame moves to the fourth station. A second of the inventions may be used to transform the single face pallet to a double face pallet if desired.

Abstract: A method and apparatus for assembling an aerosol valve which are intended to assemble a valve made up of a valve body, a spring, a stem, a sealing disk and valve cap. In assembling the valve, two vertically disposed sets formed in sequence are indicated by a first "sealing disk-valve cap" set and a second "valve body-spring-stem" set. The sets are disposed one above the other so that their original orientation is retained, and are brought together so as to place the components into a specified position relative to each other in the valve, then the sets are interlocked by deforming the valve cap. In the apparatus employing the method, namely in a mechanism for bringing the sets together, a tip adapted to grip, transfer and dispose the first set above the second one is provided. By virtue of such an arrangement, the assembling of valves involves a minimum of operations and a high-capacity apparatus has been developed.
