Abstract: A connecting device for releasably securing an axle on a support plate comprising a bushing member rotatably receiving the axle, said bushing member being disposed in an aperture of a support plate, which aperture has an opening to the edge to form a narrow throat which has a dimension less than the diameter of the aperture. The bushing member has a cylindrical body with portions removed to form at least one flat surface and a retaining lever connected to the switching body in a relationship so that with the lever in a first position the body can be inserted through the narrow portion of the throat into the aperture and then rotate it to a second position locking the bushing member in the aperture.

Abstract: In an apparatus having a comparatively heavy exchangeable element there is provided a clamping device for the element with a bayonet coupling and with grips which can be folded down only after the bayonet coupling has been brought into an engaged position. When the grips are folded down, a spring is activated so that a locked clamping coupling is obtained.

Abstract: A tool holder having a bent handle and having first and second ends. The holder comprises a head comprising means for receiving the tool. The head is arranged at the first end of the tool holder. The holder further comprises an operating knob arranged intermediate the first and second ends of the holder and securing means for securing the head to the holder. An auxiliary operating knob is arranged at the second end of the holder on the handle. A multiplier system provides for the desired magnitude of movement of the tool in response to movement of the operating knob.

Abstract: A locking device for two parts, mutually displaceable telescopically, e.g. a rod glidable in an outer tube, and including a washer with resilient serrations or teeth bent slopingly upwards out of the plane of the washer, which is retained in one part while its teeth engage the other part. An operating means is adapted for urging an annular lifting means into engagement with the teeth on actuation in one direction, so that the teeth are deflected out of engagement, allowing free movement between the parts, until they regain their engagement when the operating means is moved in the opposite direction.

Abstract: Several forms of latching mechanism are disclosed incorporating a pivotal cam and a spring-loaded plunger. In the preferred form, a lock pin is also included. The latching mechanism is particularly suited for latching interfitted members at least one of which is tubular. In one preferred form, the members are prevented from being interfitted by the lock pin which bars entry into the tubular member. The lock pin may be withdrawn only when the tubular member occupies a preselected orientation relative to a fixed frame member. When so oriented, the plunger's hose is received within a recess. This allows pivotal movement of the cam lever, and permits withdrawal of the lock pin. After the members have been interfitted, the lock pin is reinserted by pivotal movement of the cam lever. In its reinserted position, the lock pin enters aligned slots in the members, thereby locking the interfitted members together.

Abstract: A coupling device for containers adapted to retain the containers in a correct position in relation to each other and/or the walls in the holds of a ship wherein a turnable shaft having a locking head at each end thereof facing in opposite directions and being angularly displaced in relation to each other in turnable through three distinct positions by means of an operating handle to lock the device in place.

Abstract: A gas pump lever blocking member including an elongated member with a first end adapted to engage the lever and a second end adapted to engage the lever guard in a plurality of positions corresponding to varying gas flow rates through the pump. The elongated member has a stepped portion proximate its second end defining a plurality of guard engagement surfaces lying in planes disposed along an elongation axis of the member.

Abstract: A specialized sign fitting together with the process of using said sign fitting to install signs on sign supports, such as walls, is disclosed. The specialized sign fitting includes a threaded male member having a protruding attachment member, such as a wood screw, for fastening to the back of the sign. The fitting has an overlying female member having the external configuration of a bolt. This mounted bolt configured female member is used to rotate and fasten the male member at the protruding attachment member into the sign. With a plurality of fasteners installed on the back of the sign, the female members are removed to expose male member mounted scribes. In the shop, these female member mounted scribes are then impressed with the sign iself onto a sign mounting templet. In the field, the templet containing both the scribed locations of the sign fasteners as well as typically an outline of the sign is first hung on the sign mounting location.

Abstract: A quick attachment device for a tractor which has lift arms for supporting an implement, such as a loader bucket, lift fork, or the like. The rear side of the implement has two spaced-apart attaching portions in the form of hooks faced toward each other, and an attachment plate is held by the tractor lift arms and the lower edge is first positioned into the lower implement hook and then the plate is slid upwardly until the upper edge is engaged in the implement upper hook. A spring-loaded pin then automatically falls into a hole in the implement to secure the plate relative to the implement and thus attach the implement and plate together. A release cam is attached to the pin for withdrawing the pin and the attachment plate can then be manuevered out of the implement hooks to be removed from the implement when release is desired.

Abstract: Drilling apparatus mounted on a self-propelled base equipped with a joint to permit use on uneven terrain and drilling at various angles with respect to the terrain surface; embodiments of the invention feature suction apparatus for removing drill cuttings, and foldable masts.

In the field, the templet containing both the scribed locations of the sign fasteners as well as typically an outline of the sign is first hung on the sign mounting location.

Abstract: A torque transmitting coupling of a type having a housing with an opening therein which has a plurality of longitudinal splines along one part thereof and having another portion thereof which is circular. A sleeve is rotatably disposed within the circular part of the opening in the housing and this sleeve has a plurality of splines around the inner periphery thereof. The sleeve has a pin attached thereto which extends through a radial slot in the housing. A collar is slideably received on the exterior of the housing and is slideably movable in a longitudinal direction only and is biased to one position. Camming means are formed in the collar for moving the pin attached to the splined sleeve and thereby for rotating the splined sleeve from a first position which locks a shaft into the coupling to a second position which unlocks the shaft to be used in conjunction with the coupling. A free spinning shield is disposed around the housing.
