Abstract:
A safety guard structure for protecting personnel from injury while operating a machine such as a punch press. The guard member is supported at three points for vertical movement between upper and lower positions. At two upper points the guard is supported on rollers which roll on vertically extending parallel guides and at one lower point the guard is centrally supported on the lower end of a vertically extending rod slidable in fixed bearings. The resulting structure is not only economical to build but gives optimum guiding effect for the guard. The embodiment disclosed permits the entire guard structure to be swung outwardly to a position permitting access to the machine above the protected area.
Abstract:
A vehicle mounted parking device for use on a front wheel drive vehicle of the type having motive means and at least two front and two rear wheels. An auxiliary wheel is mounted substantially between and equidistant from the rear wheels and is mounted so as to permit movement relative to the vehicle frame between an out-of-the-way position and a lower operative ground engaging and rear end of the vehicle lifting position such that the rear wheels are raised off the ground. Power means is provided so that the auxiliary wheel may be forced under the rear of the car to raise the rear wheels and to place the rear end weight of the vehicle on the auxiliary wheel. The auxiliary wheel, when in operative position, allows lateral movement of the rear end of the vehicle with a minimum of longitudinal vehicle movement. The auxiliary wheel may be mounted so that its axis of rotation forms an angle between approximately 20.degree. and 60.degree. with the longitudinal center line of the vehicle so that the axis of rotation passes between the front and rear wheel on one side of said vehicle. The rotation of both front wheels by the motive means will cause the lateral movement of the rear portion of the vehicle said auxiliary wheel when said auxiliary wheel is in the ground engaging and rear end of the vehicle lifting position.
Abstract:
A wheeled carrier particularly adapted for transporting suitcases and like or other articles. A support for the suitcase is provided with a pair of removable ground wheels which are adapted to be stored within the support when not in use. The support is provided with a pair of links for engaging a side of the suitcase substantially at right angles to the side engaged by the support. The links are swingably connected to the support in such a manner that the links and support cooperate to support the suitcase adequately although the parts may be made of extremely lightweight elements. The suitcase support is adapted to be manually manipulated by means of an elongated member such as a walking cane, umbrella, sectioned handle, or like article.
Abstract:
A flush valve of the tilting pilot valve type in which stops are provided for the manually or pedal-actuated handle so as to provide a low volume or a normal volume as desired. In one form an attachment having a low volume stop is provided on the conventional handle housing. In another form the conventional housing is replaced by a modified housing provided with the low volume stop. In still another form an attachment in the form of a clamp is provided on the handle to provide the low volume.
Abstract:
A door lock for use with an auxiliary door holding mechanism that is in addition to the conventional door lock. An auxiliary door holding plate is adaptable to be locked and unlocked from outside the door by means of a conventional key-actuated driver bar. The door holding plate may also be locked from inside the door. The door holding plate also permits the door to be held against further opening from a partially open position. In one of the embodiments of the invention a device is employed for swinging the auxiliary locking plate from an unlocked position to a locked position by the closing movement of the door. By another embodiment of the invention the auxiliary locking plate is moved from unlocked position to locked position from outside the door after the latter has been closed.
Abstract:
A device for retarding the timing of the spark during the initial phase of acceleration of an internal combustion engine. A bar is connected to the throttle operating linkage and to a valve. Motion of the bar operates the valve to connect carburetor suction to a spark retarding motor. A timing mechanism operates the valve to remove the suction from the retard motor after the initial phase of acceleration.
Abstract:
The ground wheels of a wheeled suitcase are provided with axles, and mounting means are formed on the suitcase to permit the axles to be readily secured and removed.
Abstract:
A device for temporarily changing the ignition setting of an internal combustion engine in response to a sudden change of the suction in the intake manifold. A suction operated motor is connected to the ignition timing mechanism to control the suction operated timing of the ignition in response to intake manifold suction changes. The action of the motor is controlled for a selected time interval to reduce the suction operated spark advance for a substantial portion of a normal level road acceleration in city driving as sensed by the change in intake manifold suction.
Abstract:
A carrier for use with a foldable garment carry-on bag includes a frame within the lower half of the bag. The frame extends through the bottom of the bag and is provided with a wheeled axle. In one embodiment of the invention the upper half of the bag is also provided with a frame to obviate the usual transversely extending stiffeners and to permit securing the folded bag by a single central fastener rather than the two or four fasteners usually used on such bags.
