Abstract: A plurality of truss-like supports are secured, as by welding, and in spaced relationship, to the underside of a screen cloth. The supported screen cloth is then removably secured in position in a vibrating frame to form therewith a vibrating screen. Each truss-like support includes a support rod formed of wire rod of predetermined diameter disposed with a major portion thereof spaced from and substantially parallel to the plane of the screen cloth, and with end portions thereof merging into the plane of the end pieces of selected wire rods forming the screen cloth and being welded thereto. A spacer wire, formed from wire rod of a diameter less than that of the support rod and to an approximate sinusoidal configuration, is disposed so that the upper tips, formed by the sine configuration, are welded to the bottom surface of the screen cloth and so that the lower such tips are welded to the upper surface of the support rod.

Abstract: A plurality of weighted springy arms are formed integral with, and so as to extend laterally, to one or both sides of, a resilient mounting strip that is disposed beneath, and in contact with, the lower surface of the screen deck of a vibrating screen. The intended vibrating action of the vibrating screen induces an oscillating movement of the weighted springy arms to effect a rapping action of the weighted ends of the arms against the undersurface of the screen deck to loosen material which may have lodged in or plugged the screen openings and to unclog same.The resilient strips disposed on the extreme sides of the screen need only have weighted springy arms on the side thereof towards the central portion of the screen deck if space on the other side of the strip does not permit proper disposition and action of such an arm; while the strips disposed in the central section of the vibrating screen have arms extending from both sides of the resilient strip.

Abstract: Plates, of steel or other suitable material and which are appropriately sized, are welded together to form a fabricated swing jaw body for a jaw type crusher. The barrel, disposed proximate the upper extremity of the swing jaw body and which houses the bearings and shaft that operate the swing jaw, is formed either: from a continuous plate rolled into a cylinder of proper size and welded into the swing jaw body; from a number of plates welded to each other and to the swing jaw body to form therewith a cylinder like enclosure for said bearings and shaft; or from a number of plates with openings formed therethrough and stacked and welded one against the other and to said swing jaw body to form said enclosure. A piece of non-rectangular bar stock is secured proximate the bottom of the swing jaw body and has formed therein a seat for the toggle plate mechanism of the crusher jaw.

Abstract: A web of flat polyethelene stock is drawn from a supply roll by a web feed mechanism, to be fed thereby up over a tube former then down, in tubular configuration, about a material fill pipe and then to and through pouch forming and weighing stations. A first spring biased nip roller, of the web feed mechanism, urges the flat polyethelene stock into engagement with one side of an appropriately powered drive roller, of the web feed mechanism, to effect the unreeling of the stock from the supply roll and to direct same up towards the tube former; while a second spring biased nip roller, of the web feed mechanism, urges the tubular stock into engagement with the other side of said drive roller to draw the stock down through said tube former and to and through said pouch forming and weighing stations.

Abstract: Two embodiments of a keeper for retaining the ends of a pair of idler rolls within upwardly opening apertures in a bracket having a pair of outwardly extending ears are disclosed; both embodiments are executed in a malleable metal that retains a set once it has been manipulated into locking engagement with the ears on the bracket. The first embodiment of the keeper comprises two interlocking metal members of substantially similar configuration, each member having a body with a shallow crease, a leg with an aperture defined therein depending from one end of the body, and a tab projecting from the opposite end thereof. The members are interlocked with one another by inserting the tabs into the apertures in the opposing member. The second embodiment of the keeper comprises a unitary member having a body with pivotable legs at opposite ends and depending flanges at opposite sides thereof. The legs have apertures defined therein so that the keeper can be secured in locking engagement with the ears on the bracket.

Abstract: A heat and pressure consolidated laminate in which the back most sheet has fused thereto a surface film composition of polyvinyl alcohol, animal glue or starch which serves a glue line to which conventional glues adhere, the film being adhered to the back most sheet during heat pressure consolidation of the laminate by transferring the same from a release layer to the back most surface of the laminate and fusing the transferred film to the thermosetting resin impregnated in the back sheet.

Abstract: This invention relates generally to a handling system and method of arranging a group of cans into a predetermined pattern and thereafter transferring successive groups of arranged cans to a pallet to form a series of layers of cans thereon. More particularly, this invention includes an endless conveyor means for successively feeding a series of cans along a first predetermined path with means located adjacent said endless conveyor for arranging cans moving along the endless conveyor into two rows of longitudinally staggerd cans as they move along the conveyor. Operatively associated with the can feeding and orienting means adjacent one end thereof is pushover mechanism for moving substantially simultaneously the two rows of the oriented cans from the conveyor onto an accumulator tray. A receiving pallet means is supported adjacent the can accumulator means.

Abstract: A tubular member of predetermined length is arranged in an ornamental fasion, such as a helix disposed in conical or cylindrical configuration or as a festooned member, and is adapted to contain a first fluid, such as water, and to receive a second fluid, such as air, which is lighter than water and which passes through the first fluid in pockets separated one from the other. Seat defining means are carried by the tubular member as either a continuous or discontinuous strip and so as to receive illumination means which when illuminated coacts with the first fluid and the second fluid, as it passes through the first fluid, to provide a pleasingly aesthetic effect. A conduit member may also be carried by said tubular member to act as a return for the second fluid; and suitable pump means are provided to inject said second fluid into said first fluid. If desired particles of reflecting material may be dispersed in said first fluid.

Abstract: A control system is provided for stopping the operation of a bulk material conveyor system in response to an indication that the speed of either drive or driven elements thereof are above or below acceptable amounts, that the output speed of a particular material handling component falls below an acceptable difference from the input speed to said component, or that the speed of an upstream material handling component falls outside an acceptable difference with respect to the speed of a downstream material handling component feeding material to said upstream component. Speed indication is provided by the electrical signal output from dc tachometer-generators associated with the drive or driven shafts of the component whose speed is being sensed.

Abstract: A series of flexible, substantially cylindrical tubes communicates with the hollow central shafts of adjacent idler rolls so that lubrication introduced through a grease fitting at one end of the idler roll assembly can be distributed evenly to all of the rolls. Each tube is secured in position by insertion of its opposite ends into the adjacent ends of the hollow shafts of the idler rolls. Conventionally, such shafts are counterbored and tapped at each end and thus require a thicker material shell with a smaller bore to suit the tap size; thus requiring more material and cost.

Abstract: A keeper for retaining opposite ends of a pair of idler rolls fixed within apertures in the first and second supports of a common bracket. Keeper is unitary rigid member including a planar body with a raised rib on its upper surface and a pair of shallow, substantially triangular legs depending therebelow. Such legs extend away from the body at an obtuse angle and the apex of each triangular leg is flattened slightly to form a run parallel to longitudinal dimension of the body so that legs can span the distance between the supports of the bracket and engage the wrench flats at the ends of a pair of idler rolls. Keeper is forced into locking position by simple manual tools, and once in position, the rib on the keeper is trapped between the opposite walls defining the apertures in the bracket and the reaction of the idler rolls presses on the legs of the keeper so that the keeper exhibits a self-captivating characteristic.
