Abstract: Chuck provides for each jaw an action bar extending substantially longitudinally of the chuck axis and rockable in an action plane radiating from the chuck axis and intersecting the jaw, and a pair of first and second slides for each action bar, with said slides being guided for movement in the associated action plane in opposite directions normal to the chuck axis, with the first slide pivotally supporting the bar intermediate its ends about an axis normal to the action plane, the second slide having with one end of the bar a floating pivot connection with its pivot axis extending normal to the action plane, and the other end of the bar having with the jaw a floating pivot connection with its pivot axis extending normal to the action plane, so that on moving the first slide relative to the other slide in opposite directions the bar is rocked about its floating pivot connection with the second slide as a fulcrum for opening and closing the jaw, and on moving the second slide relative to the first slide in opp

Abstract: The drum drive in a rotary shear includes a pair of driving and driven surge gears and a coupling of which the driving and driven companion members are drivingly connected with the driven surge gear and with one of the drums. The shear is adjustable for varying the length of stock cut on each revolution of the drums, and such adjustment also requires shear synchronization with the fed stock which is accomplished by disconnecting the coupling members and angularly adjusting the surge gears relative to the drums. The coupling of featured lock type has companion members with cylindrical surfaces which are normally in such an interference fit with each other as safely to transmit without slippage torque in excess of the maximum required for stock-cutting operation of the shear, yet these coupling members are disconnectible for shear synchronization by applying pressurized fluid to their cylindrical interface.

Abstract: Action disabling device in a firearm having among its conventional components a spring-closed breech bolt, a tubular magazine, and a pivoted cartridge lifter. The disabling device is in the form of an operating arm pivoted with one end to a fixed part of the action so as to be swingable with its other end into active and inactive positions in which the same is in and out, respectively, of the closing path of the breech bolt, and is normally spring-urged into its inactive position, with this operating arm being, on overtravel of the lifter in lift direction for lack of a cartridge thereon, engaged and taken along by the lifter into its active position to stop the breech bolt on partial closure of the same. The operating arm is one of the arms of a double-arm lever the other arm of which projects to the outside of the receiver and is there accessible to an operator's finger for swinging the operating arm to its inactive position.

Abstract: The outer prongs and inner expander of an anchor bolt are formed from a cylindrical metal blank with an axis, by lengthwise cutting the blank in planes which subtend different parts of the blank periphery and are inclined inwardly toward one end of the blank at identical wedge angles to the axis, whereby the blank is divided into separate prongs and a common expander, with the prongs and expander having plane companion wedge faces, respectively, and the prongs having cylindrical gripping surfaces.

Abstract: Wedge chuck having grooves in the sides of each jaw and in the adjacent sides of its way in the chuck body, of which the grooves in all jaws form a given angle with a common plane normal to the chuck axis in which all jaws move, and the grooves in each way lie in a plane normal to the common plane and to the median plane of the associated way in which the chuck axis lies, and a jaw actuator guided in the chuck body for movement in the direction of the chuck axis and carrying sets of follower keys of which the keys of each set are received with a sliding fit in the grooves in a jaw and in the grooves in the associated way, whereby on back and forth movement of the actuator the grooves and follower keys cooperate to move the jaws to and from the chuck axis.

Abstract: Method of forming a cartridge chamber in the bore of a firearm barrel, which comprises driving into the bore of the barrel from the butt end thereof a mandrel of the surface configuration of the peripheral wall and mouth of the cartridge chamber, whereby the bore metal is squeezed into close form-fit with the mandrel, and then retracting the mandrel from the barrel bore.

Abstract: Knee brace of unfolding type has a wrap-on pad with quick-fasteners on opposite sides for initial pad application to a knee, and tapes for finish application of the pad to the knee, with the pad also having stays to lend it rigidity over part of its knee-enveloping expanse while permitting ready natural flexure of the braced knee.

Abstract: Mailbox has a hinged front gate with a casing receiving a flag with lateral play for movement into raised and lowered positions to indicate "no mail" and "mail delivery", respectively. Provided on the flag and box are two ferromagnetic strips, respectively, of which at least one is a permanent magnet, with these strips being coordinated to be in the raised flag position in magnetic engagement for supporting the flag, and the strip on the flag will on opening of the gate turn with the latter and thereby disengage from the strip on the box for release of the flag for its gravitational drop to its lowered position.

Abstract: Controls for lights in a room with a swinging door for entry into and exit from the room, providing a main circuit for the lights, including a main switch normally closed to close the circuit, a time delay relay adapted, when energized, to hold the main switch in closed position for a preset time period and then shift the same to its open position, and a relay circuit, including a featured master switch of push button type having its push button in the form of a latch bolt, with this switch being mounted on the door so that the push button may serve as a latch bolt by being projectible into and retractible from an associated catch on the door jamb inside the room, with the master switch being closed to close the relay circuit when the latch bolt is retracted, and being open to open the relay circuit when the latch bolt is projected.

Abstract: A wrist brace having a wrist holder and an attached fastener strap, of which the holder is in the form of a flat sleeve for slip-on application to a wrist, with the sleeve having a thumb aperture and a length which is split to form a wrist-covering cuff.

Abstract: Semi-automatic reloading firearm is provided with a signal button which is normally urged into prominent projection from an aperture in the receiver to thereby foretell firing response of the firearm to the next pull on the trigger, and this signal button is operatively linked to the hammer of the firing mechanism so that on the firing stroke of this hammer the signal button is retracted into the aperture in the receiver to thereby foretell non-firing response of the firearm to the next trigger pull.

Abstract: Journalled in a peripheral groove in an operationally turning chuck body is a non-turning fluid coupling ring of which opposite side faces confront opposite side walls of the groove. Leading from annular ports in the groove walls are fluid passages which extend to chuck-closing and chuck-opening ends of a cylinder in the chuck body, and provided in the ring are fluid supply passages which lead to the opposite ring faces where they are in line with the ports in the confronting groove walls. The coupling ring has some lateral play in the body groove and acts as a shuttle valve in being operationally backed with either face into sealing engagement with the confronting groove wall by the pressure of operating fluid admitted to the port in the groove wall confronting the opposite ring face.
