Abstract: A safety device for a track stretcher of a tracked vehicle is disclosed. The safety device includes two half rings (14,15) held in a groove (16) of the tension rod (17) of the tracked vehicle by an elastic ring (20). The safety device prevents separation of the tension rod (17) from a support (2) connected to the roller wheel (1) upon failure of the primary thrust controlling stop device which includes a nut (22) screwed on the threaded end (21) of the tension rod (17).

Abstract: A wheel protector is formed as a tray to fit inside a dish-type truck wheel to collect lubricants and other material as an axle is removed from the truck without demounting the wheel from the truck.

Abstract: A wheel hub assembly includes an internally ventilated brake disc. The brake disc is mounted on a flange-like extension of the inner bearing ring of the assembly. Slots are formed in the flange-like extension and the brake disc acts as a cover over the slots forming cooling channels extending radially outwardly in the wheel hub assembly to the cooling apertures in the radially outer part of the brake disc. A heat insulated cover disc can be positioned between the brake disc and the slots in the flange-like extension.

Abstract: A covering ring for a vehicle wheel. The bead seating surfaces of a tire are mounted on the radially inner periphery of the rim. In order to prevent dirt and/or water from entering the space between the tire bead and the rim well, the covering ring has a width which covers the space between the tire bead, that portion of the rim which extends axially outwardly from the rim well, and the rim well. Also, provision is made that the radially inner surface of the covering ring, when viewed in the transverse direction, extends horizontally or is laterally inclined toward the outside. Also, provision is made that the radially inner diameter of the covering ring at no point of the space, which is to be covered, be greater than the radially inner diameter of the mounted tire in the bead region.

Abstract: A spare tire is provided for passenger autos to replace the usual fifth pneumatic tire and wheel assembly supplied as original equipment with autos. The tire includes a metal hub having an annular bulge to provide clearance for the brake calipers of an auto equipped with the tire. A series of rim segment assemblies with tread rubber thereon is mounted on the periphery of the hub member forming the tire rim. Each segment has a T-shaped metal member the T-stem of which is generally trapezoidal in shape and is vulcanized-bonded to a rubber block similar in shape which has an opposite surface vulcanized-bonded to a thin sheet metal segment. Each rim segment assembly is separately connected by suitable means to the hub member. A protective device guarding against tire collapse in event of failure of a bond between the rubber block and a metal member, engages the T-stem and hub member.

Abstract: A disc wheel for motor vehicles, including a disc defining equi-angularly spaced holes, screws for fixing the wheel to its support and engageable in said holes, and a hub cap attached to the disc, the improvement consists in the disc and the hub cap having cooperating bayonet-type connection means for connecting the hub cap to the fixing screws of the wheel.

Abstract: A convertible railway hopper car has parallel longitudinal beams defining the sides of a hatchway for filling the car with granular material from a spout, and hinged on the upper margins of the car sidewalls are cargo cover members which may occupy elevated positions in which they form a roof covering the entire car body except the hatchway, or idle positions hanging inside the car body. Hinged hatch elements are mounted on the cargo cover members at one side of the hatchway and are movable between extended positions closing the hatchway and secured to the cargo cover members at the other side of the hatchway, and open positions lying atop the cargo cover members upon which they are mounted. When the cargo cover members are in idle position the hatch elements hang below them.

Abstract: Apparatus adapted to be mounted on a vehicle frame for the purpose of increasing traction comprises an L-shaped framework, a first shaft rotatably mounted on the upper portion of the framework, a second shaft rotatably mounted on the framework and disposed below and spaced from the first shaft, spaced third, fourth and fifth shafts rotatably mounted on the framework and extending outwardly from the second shaft, a power source operable to rotate the first shaft, means interconnecting the first and second shafts to impart rotation to the second shaft, multiple wheels fixed in coaxial relationship respectively on the second, third, fourth and fifth shafts, track means mounted on the peripheries of the wheels, brake means associated with the first shaft and operable to fix the framework to the vehicle, and a second brake means operable to fix the framework to the second shaft.

Abstract: An aluminum or aluminum alloy wheel is disclosed for use in a back-to-back support wheel assembly in a track laying vehicle. Studs are embedded in the wheel rim edges 30 to reduce wear at the point of contact by the horns 34 of the track 36.

Abstract: A mechanism for protecting the tires of military vehicles from destruction y enemy small arms fire. The mechanism includes a plate or disk of armor material radiating from the vehicle wheel to a point slightly less than the expected radial deformation of the tire so that the disk is prevented from impacting against the terrain during severe jounce motions of the tire. As an auxiliary feature, a series of paddles can be retractably mounted on each disk for extension from the disk preferably when it is desired to operate the vehicle in mud, sand, or other soft terrains. The paddles tractively engaged the terrain to prevent wheel spin.

Abstract: A wheeled support structure for use in a vacuum cleaner or the like. The wheeled support structure includes a wheel mount on the body of the vacuum cleaner defining an outwardly opening recess having an inwardly facing lock surface. The wheel mount further defines a fixed annular bearing surface coaxially of the recess and spaced radially outwardly therefrom for journaling the wheeled support slidably concentrically mounted thereon. The wheel further includes a latch element extending inwardly through the recess and having turned latch shoulders arranged to be disposed inwardly of the lock surface for preventing axially outward removal of the latch element, thereby maintaining the wheel mounting surface slidably mounted on the bearing surface of the vacuum cleaner support wall.

Abstract: A protective member for use in securing metal coils to a transport vehicle or other support. The member is formed of hard, wear-resistant material having a coil contacting surface and an opposed surface. The opposed surface is grooved to receive a cable, chain or other securement member which spans the coil and whose ends are secured to the vehicle or other support. A plurality of magnetic strips are secured to the coil engaging surface of the block for positioning the block on a metal coil. Releasable chain or cable retaining means are carried by the member transversely of said groove.
