Abstract: A coin counting and packaging device in which a coin counting tube is precisely dimensioned so that a specified standard paper coin wrapper will just fit inside and accept the proper number of coins to fill the wrapper, the coins being fed through a loading cap which acts to sweep away any extra coins over and above the proper number, thus determining the correct count. While the coins are being loaded and counted they rest on a support pedestal projecting up into the coin tube from a base; when the tube is full, and raised off the base, the coins rest on a rim at the bottom of the tube. The coin tube has on its bottom edge a cam surface which cooperates with a mating cam on the support base, to raise the coin tube a distance such that the upper end of the paper wrapper may be pinched shut at the top of the tube, preparatory to removing the coin-filled wrapper.

Abstract: An apparatus particularly adapted to installation in large railroad diesels or other large diesel applications which provides heated coolant for circulation in the large engine during shutdown or layover periods, also providing heat for accessories and electrical charge for batteries. Main engine fuel supply is used to run a small diesel engine which drives an inverter and a centrifugal pump, the discharge of which is severely stifled or throttled, the inefficiency of the pumping action converting much of the energy of the pump into heat absorbed in the coolant which is then pumped through the regular cooling lines in reverse flow, and to accessories as desired.

Abstract: In combination with a miniature jewelers' screwdriver, or similar tool, a barrel made of a stiffly flexible material (preferably a specified plastic) incloses the shaft of the screwdriver. The barrel provides at its working or tip end a set of flexible elements combined with a head holding groove to provide a gripping head which securely holds miniature screws or similar fasteners registered with the screwdriver tip. At the barrel's other end a coil spring around the shaft of the screwdriver exerts pressure to extend the barrel's tip beyond the bit of the screwdriver so that it will act to engage and hold screw heads.

Abstract: The invention is intended for use with threaded fasteners, screws, bolts and similar devices, in their almost limitless applications to assembling objects and structures. These fasteners exist in many types, each requiring a special tool bit.On many occasions screws or other fasteners must be installed or removed in locations difficult of access and of which clear view may not be obtained, also where use of two hands is not possible. This invention is particularly intended for these situations.The invention comprises basically a combination of a barrel (11 or 811) and collar (20 or 201), preferably made of stiff but flexible plastic, which fit over and enclose a tool for threaded fasteners, either with a fixed bit or one which can accept insertable bits. The barrel (11) provides at its working or tip end a set of flexible elements (31) which act to grip screw heads and hold them registered with the tool.

Abstract: In combination with its own bit, or with a screwdriver, a barrel made of a stiffly flexible material, preferably a specified plastic, slides over the bit or screwdriver shaft, and provides at one end a gripping head for screw heads, and at the other a quick-lock clutch operated by a twist of a rotary collar. The gripping head can not only grip surely a screw head placed in it, as for starting, but can locate by feel an installed screw in a hidden recess difficult of access, and facilitate one-handed withdrawal of the screw, with sure retention of the head. The device can be made as a screwstarter, with a set of sizes and bits for all sizes and type of screws, or as barrels adaptable to the full range of available and existing screwdrivers. A split-barrel variant can be assembled with the use of threaded collars, one of which is the clutch collar and the other the gripping head, over the shaft of a screwdriver which has a widened blade, square shaft, or for some other reason requires a special adaptation.

Abstract: An emitter for ion generators or air ionizers shaped as a fan and provided with a boss which may also act as a socket, so that the emitter may be either rested on a vertical pin or needle or suspended magnetically from a fixture containing a suitable magnet. In either case, application of voltage will produce a corona discharge of electrons from points at the tips of the blades, and the emitter will revolve or spin from reaction to the forces produced by this discharge. In so revolving, it acts as a fan and induces a current of air to help disperse the ions produced.

Abstract: An improved downdraft furnace wherein two combustion grates are used, with the lower one being maintained completely covered with glowing coals, which totally oxidize combustion gases and particles passing through, with the result that the exhaust is free of smoke.

Abstract: This improvement in the field of portable winches or towing devices comprises a shell of heavy construction, which is easily movable on integrally mounted retractable wheels, and which when in its desired location and directional orientation can by its own vacuum pump, mounted thereon, create a vacuum within itself, developing thereby an immobilizing force equivalent to several thousand pounds of weight, enabling the winch mounted thereon to exert a pulling force of magnitude comparable to the immobilizing force, making possible the movement and relocation of heavy objects.

Abstract: A racket for tennis and like games which includes a handle having a substantially oval cross-section, with two flat opposite planar surfaces of dimension such that the grasp of the hand on the racket is more accurately aligned to control the orientation of the plane of the head than is the case with existing rackets. The handle may be constructed to receive a rigid hollow grip portion so that the grip portion may be quickly replaceable to change grip size or surface characteristics.
