Patent number: 10046328Abstract: Provided is a jaw crusher driving device in which a driving torque can be transmitted reliably to a rotation driving shaft to perform a crushing operation by strongly fixing a hydraulic pressure motor between a body frame of a jaw crusher and a flywheel. The jaw crusher includes a fixed tooth, a movable tooth, a rotation driving shaft rotatably supported on a body frame, and a pair of flywheels provided in the rotation driving shaft. The driving device includes: a hydraulic pressure motor in which a rotation shaft portion can rotate in relation to a motor body when pressure fluid is supplied; a connector for connecting one flywheel of the pair of flywheels and the rotation shaft portion; and a torque arm provided between the body frame and the motor body so as to prevent the motor body from rotating about an axis of the rotation driving shaft.Type: GrantFiled: February 24, 2015Date of Patent: August 14, 2018Assignee: NAKAYAMA IRON WORKS, LTD.Inventors: Hiroshi Nakayama, Hideki Tominaga

Patent number: 9169728Abstract: Bolted together first and second flanges include bolts disposed through first bolt holes in the first flange. The bolts extend at least partially through second holes in the second flange. Bolt include bolt heads, threads, and shanks therebetween. Crushable spacers disposed around the shanks of a first plurality of the bolts and contacting and axially extending between the bolt heads and the first flange. Bushings disposed around a second plurality of the bolts and contacting and axially extending between the bolt heads and the second flange. A shank outer diameter may be smaller than a thread diameter and heat shrink tubing may be disposed around the bolt shanks of at least some of the spacers. First bolt holes may extend into an open annular slot on first flange and second holes may extend partially through a forward extending annular rail of second flange with rail received within slot.Type: GrantFiled: December 8, 2011Date of Patent: October 27, 2015Assignee: General Electric CompanyInventors: Thomas Tracy Wallace, William Joseph Simpson, John Howard List, Jason Jianxin Tao, Tod Robert Steen

Patent number: 8733239Abstract: A food processor includes a base, a container having a side wall and an open end including a rim, and a lid for engaging the open end of the container in an operating position and a storage position. The lid has a top wall with a first and second principal surface, an annular ledge with a first and second side, and a food chute extending from the first principal surface generally parallel to a longitudinal axis of the top wall. The food chute has a length and extends away from the container with the second side of the annular ledge contacting the rim of the container when the lid is in the operating position. When the lid is in the storage position, the food chute extends into an interior of the container with the first side of the annular ledge contacting the rim of the container.Type: GrantFiled: July 16, 2009Date of Patent: May 27, 2014Assignee: Hamilton Beach Brands, Inc.Inventor: Michael W. Allen

Patent number: 7338000Abstract: An inner shell, which is intended for use in a gyratory crusher and which during crushing will rotate around its own center axis in a first direction, has at least one additional crusher surface. The additional crusher surface has, in horizontal projection and as seen in the first direction, a decreasing distance to the center axis. Large objects can be introduced between the additional crusher surface and an outer shell near a first end of the additional crusher surface in order to, near a second end of the additional crusher surface, be squeezed between the additional crusher surface and the outer shell and be crushed.Type: GrantFiled: March 20, 2006Date of Patent: March 4, 2008Assignee: Sandvik Intellectual Property ABInventors: Torbjörn Nilsson-Wulff, Christian Trulsson, Richard Bern, Björn Loven, Rolf Silfver

Patent number: 5323971Abstract: The materials to be treated, for instance, molded resin articles with resin films coated thereon are treated by relatively simple means to separate and remove the resin film coatings from the surfaces thereof, and are further treated to recover them as a raw-form of resin material or a resin material regulated such that its particle diameter lies within a given particle diameter range, or the materials to be treated, for instance, powder materials are pulverized and granulated. A molded resin article is crushed to small pieces, to which compression impacts based on fine vibrations are in turn applied for squeezing, and resin film coatings separated off the small pieces are removed. The thus treated small pieces are further re-pulverized, and frictional crushing impacts are applied to the thus pulverized pieces as well for polishing and size-regulation.Type: GrantFiled: October 22, 1992Date of Patent: June 28, 1994Assignee: Ein Co., Ltd.Inventors: Sadao Nishibori, Yuzp Itakura

Patent number: 4702425Abstract: Vibratory crushing apparatus is disclosed including a mandrel support housing suspended on a frame structure and providing floating support for a vertically arranged mandrel. Upper and lower collar housings are arranged upon the mandrel support housing and define upper and lower faces for crushing interaction with the mandrel. A shaft extends along the mandrel axis on bearings with opposed eccentric masses attached to its ends by hinges. The circumferential face on the upper collar is tapered for receiving relatively large materials to be crushed. Components of the crusher are of modular construction to facilitate repair and maintenance and a cylindrical ring secured to a central portion of the mandrel functions in combination with the upper and lower collar members to form a passage for conducting material to be crushed through the apparatus.Type: GrantFiled: January 28, 1986Date of Patent: October 27, 1987Inventor: David P. McConnell, Jr.

Patent number: 4588137Abstract: A vibratory crusher and method of operation are disclosed wherein an elongated mandrel has a rotatable shaft extending along its axis with eccentric masses mounted in balanced and opposed offset relation on opposite ends of the shaft, the mandrel being supported in a manner permitting floating gyratory motion of its ends which are arranged in spaced apart relation within first and second relatively fixed reaction collars or cones, the shaft being driven in rotation whereby the eccentric masses cause the ends of the mandrel to gyrate relative to the reaction collars or cones for producing a vibratory crushing effect therebetween.Type: GrantFiled: February 28, 1984Date of Patent: May 13, 1986Inventor: David P. McConnell, Jr.
