Abstract: A damped hinge and angled mounting bracket are provided to mount the damped hinge to a bin so that the lid of the bin opens freely and closes in a damped fashion. The damped hinge includes a housing and a sprocket support. The sprocketed support connects to a supporting wall. The angled mounting bracket includes a first leg and a second leg. The first leg mounts to a lid of the bin, and the second leg fastens to the housing of the damped hinge. The lid then moves freely to an open position and in a damped fashion to its closed position.

Abstract: A packing machine includes a supply conveyor arranged for advancing articles to be wrapped; a first motor drivingly connected to the supply conveyor; a second motor arranged for advancing a wrapper sheet codirectionally with the advance of articles; a sealing unit for periodically providing a transverse sealing seam in front of and behind each article subsequent to wrapping the article; and a third motor drivingly connected to the sealing unit. There is provided a circuit arrangement operatively coupled to the sealing unit for regulating a rotational position of the third motor. The circuit arrangement includes a computer having an input connected to the first motor for receiving data on consecutive rotational positions. To the computer there are applied data on dimensional characteristics of the articles and the wrapper sheet. The computer calculates, from the data, synchronous rotary positions of the second and third motors at least during periods when the sealing unit is in contact with the wrapper sheet.

Abstract: A coil spring making machine wherein the advancing rolls for the wire are driven intermittently by a transmission which receives motion from a timing shaft through the medium of a reciprocable input element and two one-way clutches so simultaneously that the rolls rotate in opposite directions (one clockwise, the other counter clockwise). The knife which severs the wire at intervals so as to separate successive coil springs is driven by the timing shaft through the medium of a chain transmission and a link which causes the knife to travel along an endless circular path and to sever the wire while the advancing rolls are at, or close to, a standstill.

Abstract: A spring coiling machine wherein the wire is fed lengthwise and is acted upon by a tool receiving motion from two coaxial rotary disc cams through the medium of follower levers which track the respective cams. One of the cams controls the position of the tool during the initial stage or stages and the other cam controls the position of the tool during the remaining stage or stages of the making of each of a series of springs. The angular position of each cam with reference to the other cam is adjustable to thereby change the timing of transmission of motion from the adjusted cam to the tool during each cycle of the machine. The positions of the follower levers with reference to the associated cams are also adjustable to thereby vary the extent of movement of the tool during each cycle.

Abstract: A grinding machine with two spaced-apart coaxial grinding wheels wherein the workpieces are transported through the space between the neighboring parallel active surfaces of the grinding wheels. A gauge monitors the length of workpieces which issue from the space and closes a microswitch when the monitored length of workpieces reaches a predetermined value which is close to or equals the upper limit of the acceptable range of lengths. The microswitch completes a circuit which causes a motor for one of the grinding wheels to move the one grinding wheel nearer to the other grinding wheel. The distance between the active surface of the other grinding wheel and a fixed reference point in the space between the wheels is monitored by a transducer which causes a motor for the other grinding wheel to move the latter toward the one grinding wheel when the aforementioned distance reaches a preselected maximum permissible value while the gauge closes the microswitch.

Abstract: Apparatus for heating coil springs or other metallic commodities has a furnace defining a chamber for one or more upright cylindrical supports which form part of a conveyor system for moving an endless chain or band lengthwise so that successive holders of a series of equidistant holders for coil springs on the chain or band advance through the chamber. The chain or band is trained around the cylindrical support or supports in such a way that it forms at least one helix during travel through the chamber, and around one or more pulleys or sprocket wheels located outside of the chamber and being driven by a variable-speed motor. The helical configuration of the chain or band portion in the chamber of the furnace lengthens that portion of the path for the holders which is located in the chamber and thus prolongs the intervals of dwell of successive springs in the furnace.
