Abstract: A blind riveting tool of the type employing a reuseable mandrel carrying a plurality of headed rivets to be successively installed has its nose portion provided with members closeable to abut the heads, respectively, during rivet setting and openable to permit passing of a rivet between the members. A part at the front of the tool is conveniently shiftable to hold the members open for reloading of rivets, or for maintaining the members closed during a rivet setting stroke.

Abstract: A punch press comprising multi-station, progressive die tooling, for providing metal covers with easy-open closures, is fitted with a work transfer mechanism facilitating successive positioning of the covers, the tooling employing features thereof to precisely locate and align the covers in the respective stations. More especially, in addition to cover operating dies and work supporting members facilitating lateral accommodation and positioning of the covers to avoid unwanted deforming stress therein, correct vertical alignment of the tooling at successive stages to produce the closures is economically assured.

Abstract: A fastener, for instance a wide staple having holes in its legs, is heated to a temperature above the softening temperature of the material of a heel to be attached to a shoe. The fastener is then inserted through pre-formed slots in an insole of the shoe and pressed into the heel so that heat from the fastener softens the plastic and the fastener becomes embedded in the heel to hold it attached.

Abstract: A drive chain cooperative with a guide for successively advancing can bodies (or the like) coaxially is pivotally fitted with longitudinally spaced driving lugs adapted to grip the respective trailing ends of the bodies and thus prevent their unwanted shifting about their longitudinal axes. Each lug, in addition to its projection for gripping the trailing end, has a flat portion, slidably engageable with the guide to insure non-deviation of side seam body joints from alignment with a solder applicator. A sprocket beyond the guide and the applicator, and with which the chain is in mesh, has circumferentially spaced protrusions which pivotally actuate the lugs to release the can bodies for further processing.

Abstract: A method of rapidly heat setting a shoe on a last wherein the shoe is subjected to dry air at elevated temperature, the air moving at a velocity at the shoe exterior of not less than five (5) meters per second for not more than three and one-half minutes. The method achieves shape retention in a lasted upper with improved efficiency.

Abstract: Apparatus for applying solder to the inside openings of successively fed can body side seams comprises a heated stub horn extension housing a reservoir for molten solder, a solder applicator for directing solder downwardly from the reservoir to the seams, a valve for controlling solder flow from the applicator, and an automatic mechanism operable when no cans are present thus to be soldered for rapidly resupplying the reservoir with solder from a main supply pot. Can body feeding is automatically restarted when a desired solder level in the reservoir is attained.

Abstract: A novel method of making an easy-open can end closure for insuring better control over the integrity of the closure, especially in tougher sheet metal such as steel, comprises the steps, after forming and longitudinally scoring-to-fracture the closure, of (a) providing a swageable strip of the metal extending along an edge of the line of fracture and overlying that edge, and (b) then swaging and dilating that strip radially into more intimate overlapping relation to the line of fracture to cause it to tightly close.
