    Abstract: A motor vehicle traction aid device including a plastic bag containing a sand mixture for insertion under a tire on a drive wheel of a motor vehicle for improving traction on ice, snow or the like. The bag is partially filled with the sand material and includes a foam or sponge rubber tab on one side. The bag is inserted between the driving surface and the tire of the motor vehicle such that the tab engages the tire. Rotation of the wheel toward the driving surface causes the tire to engage the tab, drawing the bag and the sand material under the tire in a rolling action, bursting the bag and dispensing the sand beneath the tire.

    Abstract: A device is disclosed for improving the traction of vehicle wheels, particularly for use with an automotive vehicle rendered immobile in snow or sand. A plate is provided with transverse T-shaped gripping members affixed to the plate on each surface for the entire width of the plate. Accordingly, positive traction is provided to both the vehicle wheel and the soft or slippery material, such as snow, sand, mud, or ice in which the wheel has become embedded. The invention is easily handled and used, particularly in emergency situations, and is durable under repeated conditions of hard use. Each T-shaped transverse bar constituting the gripping means is mounted preferably at an angle of about 25.degree. for presenting a positive gripping surface to enable the wheel to travel along the length of the traction device. Furthermore, the transverse bars provide rigidity to the device and are constructed to avoid damage to the tire. The device can be made of any suitable material, such as a lightweight aluminum alloy, high strength molded plastic, and like materials or combinations of materials.

    Abstract translation: 公开了一种用于改善车轮的牵引力的装置，特别是用于在雪或沙中不动的机动车辆。 板在板的整个宽度上设置有固定在每个表面上的板的横向T形夹持构件。 因此，车轮和软的或光滑的材料（例如雪，沙子，泥浆或冰已经嵌入轮子）中都能提供积极的牵引力。 本发明易于处理和使用，特别是在紧急情况下，并且在重复使用的条件下是耐用的。 构成抓握装置的每个T形横杆优选地以大约25°的角度安装，以呈现正的抓握表面，以使得轮沿着牵引装置的长度移动。 此外，横向杆为设备提供刚性并且构造成避免损坏轮胎。 该装置可以由任何合适的材料制成，例如轻质铝合金，高强度模制塑料，以及类似材料或材料的组合。

    Abstract: Vehicular road traction apparatus feeds a traction portion of an endless chain between a tire and the road surface and a recirculating portion of the chain is picked up aft of the tire and fed into a conduit which conducts it back to a point fore of the tire where it is fed continuously under the tire as the traction portion. The conduit is supported in position by arms and pivot pins so that the conduit may be moved between the aforesaid feeding position to a non-feeding position where the chain is held away from the tire. A cable moves the conduit between the two positions. The conduit may be hinged midway in its length so as to move its feeding and pick-up ends farther apart to stretch the chain taut in the non-feeding position. The conduit may be located outside or inside the tire. When located inside the tire, a skid plate and guide bar assist the supporting means to locate the feeding end of the conduit in proper feeding position.

    Abstract translation: 车辆道路牵引装置将轮胎和路面之间的环形链的牵引部分进给，并且链的再循环部分被拾取在轮胎的后部，并被馈送到导管中，该导管将其导回到轮胎的前方， 在轮胎下连续供给作为牵引部。 导管通过臂和枢轴销支撑在适当的位置，使得导管可以在上述进给位置之间移动到链条远离轮胎的非进给位置。 电缆在两个位置之间移动导管。 导管可以在其长度的中间铰接，以使其进给端和拾取端更远地移动，以在非进给位置拉伸链条。 导管可以位于轮胎外侧或内侧。 当位于轮胎内部时，滑板和导杆有助于支撑装置将导管的进给端定位在适当的进给位置。

    Abstract: An accessory adapted to be wedged under a traction wheel of a vehicle to allow production of traction upon rotation of that wheel. This anti-slipping accessory is characterized by cleats laterally offset from each other transversely of the accessory to preserve the tractive efficiency even though the supporting surface has been plowed by the cleats; and also, by having a leading end allowing convenient wedging under a roadwheel and gripping of its tire. This accessory includes two converging strips of bendable material, crossbars extending transversely of these strips and simply secured thereto, cleats projecting endwise from one face of these strips and laterally offset from each other transversely of the strips, a crossbar at the leading end adapted to engage notches of the tire of the roadwheel, a crossbar at the trailing end adapted to minimize throwing of the accessory, and advantageous securement of each cleat to both the corresponding crossbar and the corresponding strip.

    Abstract: A traction pad for an automotive vehicle having pneumatic tires, that comprises a flat, flexible mat formed with transverse treads on its upper surface. Studs embedded in the mat extend out of the smooth bottom surface of the mat for engagement with a slippery roadway. The mat is rectangular and has long beveled side and end edges to provide an incline on which the wheel can roll. Each stud has a cylindrical body with a reduced diameter cylindrical pin portion extending outwardly axially of one end thereof. Ridges are provided on the bottom surface between rows of protruding stud pin portions to cooperate with the studs in holding the mat in place on the roadway. The ridges elevate the pin portions from the carpet on the floor of the vehicle when the pad is stored thereover and being used as mat thereupon. Draglines may be attached to an end of the mat.
