Patent number: 8764367Abstract: A separator separates sheets from a bundle. Slack in the strap used to raise and lower a clamp is used to determine when the clamp reaches the bundle. A non-horizontal conveyor tilts beneath the clamp to receive multiple articles, and then tilts over another bin to deposit the articles. The second bin includes an angled surface, which is straightened to shift the articles for clamping. The clamp is supported by, but not attached to, a support connected with the drive. When the clamp reaches the pile, the clamp stops but the support may continue to move. The clamp is tiltable. The article is transferred by an air jet onto a surface with a roller separated from the surface. Upon transfer, the roller forms a nip with the surface. The article is deposited on an exit conveyor having a flexible, raised portion.Type: GrantFiled: June 1, 2011Date of Patent: July 1, 2014Inventor: Stanley G. McCabe

Publication number: 20100003114Abstract: A lug tender includes a conveyor belt-type feed bed having flexible conveyor belts for transporting lugs from a first, feed end, between side guard rails to a hopper or dumping end. At the hopper end, the side rails are omitted so that a grasping mechanism can address the side walls of the lug, grasping same and rotating the lug, inverting the lug over a feed hopper. Fruit carried by the lug is thus deposited in the feed hopper. A guard placed over the feed hopper prevents the lug from entering the feed hopper. A pusher bar displaces the lug across the guard to free up the hopper for the subsequent lug. The emptied lug can then be removed either manually or mechanically for recycling.Type: ApplicationFiled: July 7, 2008Publication date: January 7, 2010Inventor: John Mather

Patent number: 6250871Abstract: A conveyor (20) for transporting and inverting strap pans (22) or other pans used for baking. The conveyor includes a closed-loop drive chain (26) to which a number of pan cars (54) are pivotally attached. The pan cars are provided with magnetic bars (36) that create attractive force to hold the strap pans to the pan cars. The conveyor also includes an incline guide (204). When the conveyor is actuated, the pan cars run against the incline guide so as to cause the initial inversion of the pan cars. As the pans cars are inverted they abut against a positioning rail located along side of the drive chain. The positioning rail is shaped to control both the rate at which the pan cars are inverted from their normal upright position and then it is further shaped to force the pan cars to then return to their initial upright position. The inversion of the pan cars causes a like inversion of the strap pans secured to the pan cars.Type: GrantFiled: February 10, 2000Date of Patent: June 26, 2001Assignee: LeMatic, Inc.Inventors: Dale J.

Patent number: 5086947Abstract: The dispenser comprises a feed belt (C) provided with transversely-arranged, equally-spaced tubes (3) receiving the articles to be dispensed which are held therein by stationary boundary walls. While being transferred between two magazines (1-2) in which it is to be stacked, the feed belt is submitted to a slight temporary torsion in the longitudinal direction, so that one end of the tubes will be directed downwards and upon passing in registry with an underlying opening (9) it will permit the articles housed within the tubes to be discharged by the action of gravity. In the upper portion of the guide (F) submitting the charger to said torsion, there is provided an opening (13) with which the top ends of the tubes on the feed belt become aligned during the step-by-step movement of the latter in a direction opposite to the dispensing direction, in order to fill the tubes with new articles to be dispensed.Type: GrantFiled: April 19, 1991Date of Patent: February 11, 1992Inventor: Giorgio Bragaglia

Patent number: 5086790Abstract: A method and apparatus for opening cigarette packs involving minimal contact with the cigarettes in the pack and little likelihood of damage or degradation of the tobacco contained in the cigarettes. The invention includes conveying packs to a first location where they are received, moving the packs to a second location where they are pressurized and expanded, moving the pressurized expanded packs to a third location where one end is cut off, moving the packs to a fourth location where impulse is applied to the pack as a whole, resulting in the transfer of the pack to a fifth location, where the motion of the pack itself is stopped, but the inertia of the cigarettes themselves is conserved sufficiently that they are transferred to a conveyance for further processing. The empty packs are disposed of at a sixth location. The method and apparatus is intermittent, involving regular starting and stopping motions.Type: GrantFiled: April 23, 1990Date of Patent: February 11, 1992Assignee: R.

Patent number: 4944647Abstract: A high capacity machine cuts the tops of plastic bottles and inverts the bottles for discharging their contents. Bottles are conveyed through the machine by a feed screw. At the cutting station means are provided for standing the bottles erect so that they engage a stationary knife just below the top for cutting off the caps. Guides downstream from the cutting station maintain the bottle in the screw and invert it underneath the screw for dumping. The cap is not completely severed but a minor portion of the circumference is left intact to serve as a hinge between the cut bottle and cap. The cap is kept more or less erect as the bottle is inverted to avoid interference with discharge of the contents. At the cutting station a support screw is rotated synchronously with the feed screw by interengaging teeth on the crests of the threads of the two screws.Type: GrantFiled: April 29, 1988Date of Patent: July 31, 1990Assignee: Alpha Therapeutic CorporationInventors: John C.

Patent number: 4454807Abstract: A storage system for large quantities of flowable, granular materials, such as grain. The material is covered by flexible cover sections which are spread out on an impervious support surface and thereafter laced together to define a cover having a centrally located opening. The cover is grasped in the region of the central opening and lifted to a predetermined fill height; the perimeter of the cover being free to pull inwardly as necessary accommodating the lifting. Thereafter, the granular product is introduced into the opening until it reaches the predetermined fill height and defines a pile extending downwardly toward the support surface along a natural angle of repose. As the pile grows, it raises the cover while sweeping it upward away from the center of the pile. By this means the entire finished pile is conformably covered by the cover.Type: GrantFiled: July 6, 1982Date of Patent: June 19, 1984Inventor: Paul P. Wolstenholme

Patent number: 4294292Abstract: An automatic tumble dumper for automatically removing the electrolyte from lead-acid storage batteries and particularly batteries intended for automotive use is disclosed. The device comprises carrier means adapted to transport the batteries through the system. Once the batteries are inside the unit, upset means automatically turn them first onto their side and then invert them so that the bulk of the electrolyte passively drains out. To achieve complete electrolyte removal, the batteries are jostled via a jostling means which cooperates with said carrier to actively shake the batteries as they travel through the device. At the conclusion of this shaking, now drained batteries are returned to an upright position and travel out of the machine for further processing.Type: GrantFiled: November 1, 1979Date of Patent: October 13, 1981Assignee: General Battery CorporationInventor: William J.
