The sifting box is adapted to nest or stack in the base box. Opposing outer portions of the sifting box bottom are inwardly sloped at an angle which is less than 90.degree. relative to the bottom of the box and the sifting perforations are confined between these sloped opposing outer portions.

Abstract: An easily assembled pre-milled railing system having upper and lower rails supported between spaced newel posts and a plurality of balusters disposed between the upper and lower rails. The balusters have upper and lower ends with respective parallel aligned spline grooves that continuously extend across the balusters ends. The upper rail is provided with a continuous elongated spline groove extending along the bottom side thereof. The lower rail is provided with a continuous upwardly projecting spline tongue that extends therealong on the top side and penetrates the lower end spline grooves of the balusters. An elongated spline has an upper side continuously received in the upper rail spline groove and the lower side of the spline is received in the upper end spline grooves of the spaced balusters. The elongated spline is first secured to the upper end of the balusters by nailing downwardly through the spline into the upper ends of the balusters.

Abstract: A collapsible push up exercise device having hinged flared sides which, when opened for use, form an inverted V-shape. A plurality of spaced holes are provided on the front sides of the hinged framework for the reception at selective heights of hook-like extensions of two partially closed rings which rings encircle and support a push up bar.

Abstract: A hollow single die, of a pair of dice for carrying an object and having a ring attached to one corner, to which ring is connected, one end of a flexible carrying chain, the other end of the chain being attached to a key carrying ring.

Abstract: A sportsman's mitten which has a flexible hand enclosing glove member that is adapted to enclose and confine a human hand therein in a non-extended closed configuration. An outer-most distal end of the mitten enclosure is slit open to provide an opening for permitting extension of the enclosed fingers of the hand such that they can extend therethrough and beyond by merely extending ones fingers outwardly from the closed configuration. A conventional hook and loop fastener mechanism temporarily closes this distal end opening and is adapted for easy quick opening again by mere extension pressure applied thereto by the outward extension of ones fingers from the closed or fist-like configuration.

Abstract: A portable masonry pier constructed of a used steel drum, a reinforcing rod frame which surrounds the drum in a masonry wall which is laid up around the frame and secured with mortar to the frame. The mortar is also internally confined by the drum. Removable fasteners secure the frame to the drum and are provided with lifting rings to lift and move the composite pier structure as a unit.

Abstract: An apparatus for pressurizing a pneumatic tire mounted on a vehicle wheel which includes a displacement type air pump having a spring loaded piston and cylinder combination for generating air under pressure. The air pump is axially attached to the vehicle wheel and an air pressure connection conduit introduces air under pressure generated from the pump into the pneumatic tire. A cam and cam follower arrangement is mounted in the housing for the pump for creating relative cam actuated movement therebetween which is utilized for driving the air pump. A pendulum is mounted for free axial rotation relative to the pump housing and the pendulum is connected to one of the cam or cam follower, and the other is secured to the pump housing for rotation therewith to provide this cam actuated driving movement. The axis of piston reciprocation in its cylinder is substantially aligned axially with the wheel axis of rotation.

Abstract: An adjustable snow making tower structure which includes a device for warming the tower structure for preventing ice and snow buildup and for precooling the water before it is supplied to the tower for manufacturing snow. The snow making tower is usually an elongated pipe configuration which is secured at its lower end to the support arm, and the snow making nozzles are provided at the upper end of the pipe tower. The support arm is utilized for raising and lowering the pipe tower between horizontal to vertical. The support arm is made of heat conducting tubing and is connected to a remote water supply and is connected for conveying water under pressure through the tubing of the support arm to the bottom end of the pipe tower. Accordingly the water being conveyed through the support arm warms the support arm and is precooled prior to being conveyed to the snow making nozzles at the top of the tower to provide better quality snow with greater efficiency.

Abstract: An automated system to draw detailed networks for use in various types of engineering analysis. A set of active node sites are available that are specified by entering the node number and selecting the desired node. Unused node sites can be removed or shown again as necessary. Elements between nodes are then automatically drawn by specifying the node start and node end of each element and selecting a draw command by utilizing stored data arrays and coordinate based graphical system software. Elements can also contain various attributes types that are automatically drawn if selected. Values stored in the unique data arrays are available for use in engineering computations, as well.
