Abstract: Shotgun barrel retainer in which the barrel is pivotable about a hinge pin supported by the laterally spaced arm portions of the gun frame by means of a depending barrel lug disposed between the arms of the frame and having a semi-cylindrical recess engaged with the forward portion of the hinge pin. A coil spring urges the barrel outwardly to maintain the barrel lug firmly engaged with the hinge pin having at one end a shoe or saddle member engaged with the cylindrical surface of the hinge pin opposite the barrel lug and being compressible between the hinge pin and a second barrel lug toward the fore-end of the barrel. A resilient leaf spring is carried on the hinge pin and is disposed between the frame and the barrel lug. The leaf spring, in combination with the coil spring and shoe member, serves to retain the barrel in fixed position on the frame and prevents undesirable relative motion therebetween when the barrel is pivoted to an open position.

Abstract: A system for distributing successively formed groups of glass gobs from a feeder bowl to the several individual sections of a Hartford I.S. type glassware forming machine includes a single scoop for each gob in the group, and mechanism for rotating the scoops between successive positions wherein each is aligned with a chute associated with a particular mold cavity in each machine section. A "double-gob" installation is described and the two scoops have associated annular spur gears which are driven in unison by a reciprocable rack gear through a predetermined schedule of angular displacement to successively align the two scoops with several sets of paired chutes according to a particular order and to then repeat this schedule. A cam follower connected to the rack gear causes programmed movement thereof in response to rotation of a cam having lobes of predetermined height to produce the predetermined schedule of angular displacements of the scoops.

Abstract: A drive for moving a container processing apparatus at a substantially uniform speed with a line of containers advancing on a conveyor is disclosed in a machine wherein glass bottles are to be pressure tested and the processing apparatus comprises at least one pressure testing head. The pressure testing heads are cyclically swept along a segment of a moving conveyor on which the bottles to be tested are carried and, in order to substantially synchronize the speed of the pressure testing head with the uniform speed of the bottles on the conveyor, the pressure testing head is mounted on the orbiting link of a parallel crank, four bar linkage which is rotated by means of a rotational drive mechanism having an elliptical gear set. The gear set provides a variable drive ratio and, when driven by means of a constant speed motor, modulates the speed of the orbiting link and the pressure heads so that the heads sweep into engagement and accurately track the bottles during the pressure testing portion of the orbit. The elliptical gears also cause the pressure heads to travel along the return portion of the orbit at a more rapid speed in preparation for the next pressure testing cycle.

Abstract: Individual precut and prescored tray blanks are withdrawn from a stack and fed to an infeed station of the machine, each blank being provided with adhesive while enroute to said infeed station, and each blank being oriented with its end flaps in radially spaced relationship with respect to the axis of rotation of a mandrel which moves upwardly from beneath the blank to engage it at the infeed station and move it upwardly against four fixed corner tab deflecting plows. The inner radial edge of the blank is engaged by a pair of pivotally mounted fingers which fold the inner end flap through 90* as the blank is moved downstream by the mandrel. Projecting portions of these fingers also fold the corner tabs through 90* with respect to the inner end flap, while a pair of resilient leaf spring elements fold the outer end flap at substantially the same time. The outer pair of corner tabs are folded solely by the above mentioned fixed corner tab engaging plows. A pair of opposed side walls have upstream edges for supporting these flap folding elements, and also for supporting fixed side flap folding members so arranged as to engage the side flaps of the blank as it travels between the axially spaced side walls. The continuously moving mandrel then carries the folded tray through substantially 180* of its rotation to set the adhesive prior to arrival at a discharge station, where an eject cylinder carried within the mandrel, punches the tray downwardly so that it drops downwardly onto a take-away conveyor.

Abstract: Segregated groups of articles are mated with an initially flat blank which is then folded into a U-shaped configuration around the bottom, front and top sides of the group articles. A pocket chain conveyor receives the U-folded case, with its article group, and each pocket includes a rear gate for folding a trailing bottom flap upwardly against the rear side of the article group. An overhead flight bar then folds a trailing top flap, or rear panel of the blank, downwardly so that a second rear gate on the pocket chain can hold both top and bottom rear flaps in place prior to folding the laterally opposed side flaps inwardly against the sides of the case. The trailing top flap, or rear panel, has side flaps which must be folded forwardly, and this is done by spaced elements on the flight bar. These elements engage the rear panel side flaps adjacent their respective fold lines so that the rear panel is not only folded downwardly as described, but so that as the rear panel abuts the rear of the case, further forward movement of these elements creases the side flaps at their respective fold lines to fold them forwardly. The remaining side flaps are folded in a conventional manner by fixed ploughs or the like.

Abstract: Noncircular articles are fed in a single line on a primary conveyor, and a pair of take away conveyors are provided on either side thereof for receiving articles diverted from the primary conveyor. A pair of pocket chain conveyors have facing runs traveling downstream at a slightly slower speed than that of the primary and take away conveyors. U-shaped pockets are mounted at staggered locations on these pocket chain conveyors, and move inwardly to releasably grip the articles to be diverted, and once an article has been so gripped these pockets move outwardly to divert the article onto an associated take away conveyor. An article-stripping bar acts on the article so diverted, releasing it from the U-shaped pocket, which pocket then travels upstream for diverting another article. With two take away conveyors, every third article is allowed to pass between the pocket chain conveyors and three discrete lanes of articles are provided.

Abstract: At the blank mold or parison forming station of a glassware forming machine a neck ring mold mates with a blank mold to form an inverted parison cavity with a top opening into which a molten glass charge is dropped. A vertically reciprocable plunger is arranged to close the bottom of the cavity and a baffle subsequently closes the top opening. A plunger operating mechanism then raises the plunger to force the molten glass charge outwardly against the walls of the cavity, and especially into the neck ring mold, after which the plunger is withdrawn, and the blank mold and baffle are removed. The neck ring then swings the inverted glass parison over to a blow mold station for further forming. The plunger is free to float laterally in its holder to accommodate variations in alignment therebetween, and the baffle floats vertically to accommodate variations in the size of the molten glass charge.
