摘要： The railway truck disclosed herein is provided with a split axle composed of two transverse aligned axle members each having mounted on the outer end thereof a rail wheel. The inner ends of the axle members in one embodiment are connected by means forming a movable joint between such inner ends to enable the axle members to be moved to raise the rail wheels from the tracks, such connecting means also including means to restrict the relative movements of the two axle members. In this embodiment the two axle members are pivotally connected to the vehicle by means which enables lateral movement of such members during such relative movements thereof. Means are provided to raise the jointed inner ends of such axle members to raise the rail wheels. In another embodiment, the outer end of each axle member is supported by a main load carrying floating bearing construction permitting movement of such member about a pivot point located directly above the rail. The inner end of each axle member is supported by a bearing construction slidably mounted in a housing to permit of transverse movement of such inner end about said pivot point. The housing includes means to restrict and cushion the transverse movements of the inner end of the axle member. In both embodiments, the axle members are disposed at an angle of less than 90.degree. to the vertical so that the wheels are tilted inwardly from the vertical. Further, the rail wheels each have a riding surface which converges toward the flange thereof so that a line projecting inwardly from such surface is disposed at a given acute angle to the central longitudinal axis of the wheel axle.THE INVENTIONThis application is an improvement over my original application Ser. No. 542,960, filed Jan. 22, 1975, now U.S. Pat. No. 3,945,326, issued Mar. 23, 1976, for Railway vehicle with additional subject matter.This invention relates to railway vehicles and provides distinct advantages for those urban and suburban transportation systems which are based upon the use of a vehicle designed for both rail and road operations such as the type of vehicle disclosed in my U.S. Pat. No. 3,434,432 granted Mar. 25, 1969.In the operation of the vehicle disclosed in my aforesaid patent, it made its transfer from the rail tracks to the roadway and vice versa, at given locations by means of ramps constructed to cause the pneumatic tires riding thereon to lift the rail wheels associated therewith onto and off the rails depending on the direction in which the vehicle was traveling on the ramp. This method of transferring the vehicle required major changes to the rail right of way, in the removal of switches and modification of the same, that were costly and impractical.A further problem, and this is not limited to the type of vehicle disclosed in my aforesaid patent, but applies also to the standard railroad cars now in use, is the side-cutting of rails and switches and the wear on the wheel flanges due to the construction of the present type of rail wheel. Not only is this resulting wear on tires and rails a costly burden to the railroads, but the sharp-edged tire flanges produced by this wear are the cause of many derailments. The high frictional resistance involved in such unwanted wear also generates a disconcerting wheel squeal and causes considerable resistance to the operableness of the train. The added drag to a train caused by this friction necessitates that the fuel consumption thereof be greatly increased over that otherwise required. The only known method presently employed to cope with this problem is lubrication of the tracks.One of the principal objects of the present invention is to provide in a vehicle of the indicated type an improved running gear construction that will enable the vehicle to be used on existing rail beds without necessitating that any changes be made in the latter or the use of ramps.Another object of the invention is to provide an improved rail wheel design which will lessen the disadvantages of the presently constructed rail wheel and enable the vehicle to operate satisfactorily without the front guide wheels provided on the vehicle disclosed in my aforesaid prior patent.

摘要： The vehicle disclosed herein is provided with a running gear composed of two transverse aligned drive units each provided with a wheel axle having mounted on the outer end thereof a rail wheel and a tire wheel. The inner ends of the drive units are connected by means forming a movable joint between such inner ends to enable the units to be moved from positions in which the rail wheels are operable and the tire wheels are inoperable to positions in which the tire wheels are operable and the rail wheels are inoperable, such connecting means also including means to restrict the relative movements of the two drive units. The two drive units are pivotally connected to the vehicle by means which enables lateral movement of such units during the pivotal movements of the latter in one direction or the other. Means are provided to raise the jointed inner ends of the drive units to transfer the drive of the vehicle from rail wheels to tire wheels and to lower such jointed inner ends of the drive units from their raised position to return the drive of the vehicle to rail wheels. The rail wheels each have a riding surface which converges toward the flange thereof so that a line projecting inwardly from such surface is disposed at a given acute angle to the central longitudinal axis of the wheel axle. The tire wheels have a tread surface which converges outwardly so that a line projecting outwardly from such surface is disposed at a given acute angle to the central longitudinal axis of the wheel axle. The tire is mounted on a frusto-conically shaped rim of such angularity that a line projecting outwardly from such rim is parallel to said projecting tread surface line.

摘要： A magazine-protecting, ambidextrous device for carrying a loaded spare magazine attached to a firearm buttstock in position for rapid removal and insertion into the firing position of the firearm. The loaded spare magazine is restrained within a well formed in the buttstock by a retractable latch pivotably mounted such that when the spare magazine is removed, the latch retracts below the exterior surface of the firearm buttstock, protecting the latch from damage and reducing the profile of the weapon. The spare magazine is carried in such a way as to protect the open end of the magazine and the ammunition carried therein from dirt and/or damage.
