Abstract: A fastening device includes a rotational drive portion that rotationally drives a socket, an advance/retract drive portion that causes this socket to advance or retract along a rotational axis thereof, a magazine that retains a plurality of heads that retain bolts, and a switching portion that moves this magazine to selectively position one of a plurality of heads ahead and on the rotational axis of the socket. One of the heads is selected and positioned on the rotational axis of the socket by the switching portion, then the socket is advanced by the advance/retract drive portion and the head thus selected is retained by the socket, then the socket is advanced further by the advance/retract drive portion and the head to detach is detached from the magazine, and then the head is rotated by driving the rotational drive portion, thereby fastening a bolt retained in the head.

Abstract: An apparatus for aligned supply of fastening parts into an automatic assembling machine includes a rotary holding claw body, disposed at a lower position of a pressing punch, for gripping the fastening parts supplied in a position of a lateral direction by way of a supply passage, by passing through an intersection of an axial line of the pressing punch and an axial line of the supply passage, and rotating and displacing by a specific angle about a lateral axial line orthogonal to the both axial lines, and positioning and holding the fastening parts coaxially with the pressing punch at a lower position of the pressing punch. The rotary holding claw body has a pair of mutually opposing disk-shaped gripping claws, and the both disk-shaped gripping claws are forced to as to press push springs each other, and the fastening parts are gripped by the both disk-shaped gripping claws.

The assembly also includes a second body portion adapted to receive the pin scored by the first body. The second body includes a fluid actuated pin insertion mechanism responsive to the length of the pin having a pin receiver operatively connected to a punch which pushes the pin from the receiver until the pin exits the insertion head assembly.

Abstract: A machine is disclosed for feeding button parts from a magazine to an attachment position. The machine includes an arcuate sliding surface which guides the button parts to the attachment position, and a transport finger which moves along the sliding surface. The transport finger is spring-urged outwardly to move the button parts in one direction, but is shiftable inwardly to pass over button parts when moved in the opposite direction.

Abstract: An escapement mechanism for an automatic screw feeding machine is disclosed. A rotor within a housing receives a fastener from a track feed arrangement and delivers the fastener to a delivery opening in communication with a conduit leading to the driver head of the automatic screw feeding machine. A cutout within the rotor is specially sized and positioned and the motion of the rotor is arranged so that no edges are presented which may cause the fastener to hang up or cause jamming of the escapement apparatus. A reed valve is used to open and close the delivery opening so that pneumatic apparatus may be used to drive the fastener to the driver head.

Abstract: A device for driving fasteners such as nails, screws etc., including a fastener receiver and guide for receiving fasteners in a position for co-action with a fastener-driver and for guiding the fasteners toward the intended fastener-driving location. A fastener magazine having a fastener guide channel for guiding fasteners is arranged in side-by-side relationship toward the fastener receiver and guide and a feeder is provided for feeding fasteners arriving from the magazine to the fastener receiver and guide. The feeder includes a bifurcate member arranged to co-act with the guide channel in the magazine. The bifurcate member has an elongate groove formed by tines or legs of the bifurcate member.

Abstract: An apparatus for attaching a pair of fastener elements onto a garment includes a gripping mechanism for temporarily holding one fastener element and for releasing the latter immediately before a reciprocally punch arrives at the predetermined lowermost position in which the one fastener element is clinched to the other fastener element supported on a die with the garment sandwiched between the fastener elements. The apparatus may comprises a guide mechanism including a chute having a guide track for the passage of the one fastener element, and a speed reducing device disposed in the chute for slowing down the movement of the one fastener element prior to the arrival of the latter at a retaining portion of the gripping mechanism. An overturning device may be provided in the chute for turning over the one fastener element as the latter slides along the guide track.

Abstract: Stick delivery mechanism especially for but not limited to use in a candy floss machine for delivering a stick from a storage facility to a feed position from which the stick can enter a device which rotates the stick about its own axis.

Abstract: A machine for driving a pin into a hole in a work piece. The pins are fed by gravity in a continuous succession from a pin supply to a passage extending through a pin receiving rotor. With a pin in the rotor, the rotor is turned through a selected angle to bring the pin and the passage through the rotor into alignment with a pin driving punch. Upon actuation of the punch, the pin is driven from the rotor into a passage in an adjacent aligned sliding pin guide. Movement of the pin through the pin guide temporarily ceases when the pin encounters a resilient stop. Continued movement of the punch then moves the pin guide and the pin therein until the nose of the pin guide engages the work piece. The punch, continuing to move through the passage in the now stationary pin guide, drives the pin past the resilient stop and into the aligned hole in the work piece. Upon withdrawal of the punch, the pin guide aided by a spring returns to it original position adjacent the rotor.

Abstract: A turnover mechanism for turning a planar strip through one hundred and eighty degrees is disclosed. The turnover mechanism is particularly useful in the manufacture of tackless strips and is adopted for installation in a tackless strip manufacturing machine. The turnover mechanism includes a ratchet which is activated by the usual pin driving mechanism to rotate a turner in timed sequence with the pin inserting operations. The turner includes a groove and the turnover mechanism incorporates a cam to urge one end of each strip into the groove after the pins are properly seated in the strip. The turner turns over or flips each pinned strip in sequence to permit the tackless strip manufacturing machine to automatically apply a plurality of floor attaching nails in each strip in a direction opposite to the orientation of the pins.

Abstract: A screw feed mechanism includes a pivoting magazine positioned in a housing. The magazine includes a single throughbore which receives a single screw from a feeder hose and then pivots into alignment with a drive tool. The magazine is driven by a pneumatic cylinder.
