Abstract: HAND BRAKE FOR RAILROAD CARS     Abstract of the Disclosure A hand brake for railroad cars comprising a housing including a front casing and a rear or back plate, between which an operating shaft is journaled (that bears the usual vertical hand wheel), and within which is mounted the brake drum in concentric relation to the operating shaft.  A ratchet mechanism permits winding of the brake chain in one direction only, and the winding of the brake drum is through a non-rotating but gyrating pinion that meshes with a ring gear that is part of the drum, the pinion being actuated through an eccentric sleeve that is journaled for rotation about the operating shaft.  The brake drum is journaled in concentric relation about the operating shaft on bearing plates res-pectively affixed to the housing front casing and back plate, with the housing back bearing plate having an integral annular flange in which the inner end of the operating shaft is jour-naled, and on which the eccentric is journaled.  The ratchet mechanism is also disposed within the annular flange and is clutched to the shaft through friction clutch cooperation with a nut threaded on the shaft that is splined to a jaw clutch member that cooperates with jaw clutch seats or pockets in the eccentric whereby  the operating shaft is releasably keyed to the eccentric to rotate the same for actuating the pinion for chain wind up purposes.  The jaw clutch device involved also is operative to establish the friction clutch relationship that the nut has with the ratchet mechanism whereby the tension acting on the brake chain keeps the ratchet mechanism operative to prevent rotation of the shaft in a direction which would unwind the chain.

Abstract: ABSTRACT OF THE DISCLOSURE             A readily assembled self-supporting structure for carrying an antenna and associated electronics apparatus includes a tripod base having support means for pivotably supporting a top mast on which the antenna and associated apparatus are mounted.  Pivotably joined with the support means, a mast engaging member is adapted to swing in a pre-determined direction to either raise or lower the mast.  A heavy battery pack used to power the apparatus is pendulously suspended from the member below the support means and stabilizes the structure against wind forces without re-quiring ground anchors.  In addition, the battery pack acting about the pivot erects the top mast in a perpendicular attitude irrespective of the slope of the antenna site.  The structure is held rigid by means of three guys between the top of the mast and the feet of the tripod.  One of the guys may be removed to allow the mast to swing when the battery is raised and the tripod legs are prevented from splaying at ground level by a continuous loop of wire rope passing through support pads on which the base rests.

Abstract: ROTA Y ENGINE OR PUMP CONSTRUCTION John S. Baer - Bar Harbor, Maine Abstract of the Disclosure A rotary engine or pump employs a block or housing having a cylindrical cavity along the axis of which extends a cylindrical drive shaft supported on the block to permit rotation thereof.  Within the cavity, parallel edge walls axially spaced apart from one another and rotatable relative to the shaft and the cavity define between them the bounds of energy chambers. Between these parallel edge walls are arranged an even number of outwardly directed imperforate movable walls with alternate movable walls being attached to and moving with one of the edge walls and intermediate movable walls being attached to and moving with the other edge wall, such that the edge walls and movable walls, the drive shaft and the cavity walls of the block form a plurality of essentially separate and non-intercom-municating energy chambers between the movable walls.  The movable walls of the energy chambers are rotatable about the axis of the shaft and rotate with and, in fact, drive the shaft. Inlet and outlet port means through said block are circumferen-tially spaced around the circumference of the cylindrical cavity to respectively admit fluid into the successive energy chambers which pass the inlet port means as the movable walls move apart and exhaust fluid from the successive energy chambers which pass the outlet port means as the movable walls close together. The oscillation movement of the walls with respect to the shaft is translated into rotational movement of a planet gear on a radial arm fixed to the drive shaft and driving the arm and the shaft, in turn, by its progressive rotation about a sun gear fixed to the block.
