Patent 24759 Summary

Claim lst. In a device for lubricating car-axles and similar journals, the combination of an endless screw to be rotated by contact with the periphery of the axle, or journal to be lubricated, a spring actuated or yielding support for the screw, and a worm-wheel engaging said screw, substantially in the manner and for the purpose set forth. 2nd. In a device for lubricating car axles and similar journals, the combination of a movable supporting plate, an endless screw journalled in bearings carried by said plate, and adapted to be rotated by contact with the periphery of the axle or journal to be lubricated, a worm-wheel pivoted upon the plate to engage said screw, and a spring adapted to carry and press the screw against the car axle or journal, substantially in the manner and for the purpose herein set forth. 3rd. In a device for lubricating car axles and similar journals, the combination of a supporting frame or base plate, a swinging frame or plate pivoted to said frame, an endless screw mounted to rotate in bearings carried bpi; said plate, a worm-wheel pivoted upon said plate to engage the screw, and a spring upholding the plate and adapted to carry and press the screw against the periphery of the axle or journal to be lubricated, substantially in the manner and for the purpose herein set forth. 4th. In a device for lubricating car axles and similar journals, the combination of a base plate or frame, a guard attached to the same to prevent it from turning, a swinging plate Car frame pivoted to said base, a spring to uphold the swinging plate or frame, an endless screw journalled in bearings carried by said swinging plate or frame, to be rotated by contact with the periphery of the axle, and a worm-wheel pivoted upon the swinging plate or frame to engage the screw, the base plate being adapted to be inserted in the axle box or reservoir for containing the oil or lubricant, and the worm-wheel so disposed as to be immersed, or partially immersed in the oil or lubricant when in position for use, substantially in the manner and for the purpose herein set forth. 5th. The combination with an axle or journal, of an endless screw adapted to be rotated by contact with the periphery of the axle or journal, pivoted arms between which the screw is journalled, a worm-wheel engaging said screw and carried by the arms, a base plate or support to which said arms are pivoted, a spring adapted to uplift the arms and screw, and carry the latter against the axle or journal, and a hex or reservoir adapted to oontairran oiler lubricant and from which the worm-wheel is supplied'with oil, substantially in the manner and for the purpose herein set forth. 6th. The combination of the base frame R swinging frame G, springs 0, worm-wheel L and endless screw N, substantially in the manner and for the purpose herein set forth. 7th. The combination of the base frame A, swinging frame U, springs 0, worm-wheel L and screw-threaded lubricating roller N, provided with a worm which is lost at each end P on the periphery of the, roller, substantially in the manner and for the purpose herein set forth.
