My invention relates to certain improvements invariable-speed counter-shafts, their starting, stopping, and reversing mechanism.

I claim as my invention:

1. In a motional gearing, the combination, with a longitudinally-movable rotatable shaft having a disk at one end thereof, of a carriage adjacent to and movable in a plane parallel with the face of the disk, a rotatable shaft journaled in said carriage having a disk at one end, the face of which is at an angle to said first-mentioned disk, mechanism intermediate the carriage and the longitudinally movable shaft for automatically moving the carriage when the first-mentioned shaft is moved longitudinally, and means for moving the shaft so as to place the disk into or out of contact, substantially as set forth.

2. In Motional gearing, a rotatable shaft having a disk mounted thereon at one end thereof, slideways at right angles to said shaft, carriage reciprocally movable on said slideways, a rotatable shaft journaled in said carriage and having a disk secured thereto and adapted to contact with said first-mentioned disk, two bevel-wheels mounted on said first-mentioned shaft, a bevel-wheel adapted to gear with either of said two bevel-wheels and having secured to its shaft a drum with a spiral grooved periphery, and cords connected with said drum and said carriage, said bevel- wheel shaft having its bearing movable on said first-mentioned shaft, said parts being combined substantially as described.

3. In a motional gearing, the combination, with a driven disk and a slideway adjacent thereto and parallel therewith, of a movable carriage upon the slideways, a driven disk upon the carriage at a slight angle to the other disk and adapted to be moved entirely across its face, a lever for moving the disks into and out of engagement, and automatic means for moving the one disk across the face of the . other when the lever is operated, substantially as set forth.

4. In a frictional gearing, the combination, with two disks, one of which is movable entirely across the face of the. other, of a shifting bar capable of movement in two directions, at substantially right angles to each other, and means for connecting the bar with the disks, whereby the movement of the bar in one direction will place the disks into or out of contact, and a movement in the other direction will vary the direction and rate of speed of the disks relatively to each other, substantially as set forth.

5. A variable-speed counter-shaft, consisting of a supporting-frame, a driving-shaft mounted therein, a driving-disk at its forward end, an arm or lever pivoted to the rear hanger, a yielding spring engaging with said arm, means for adjusting the force of said spring, a pivoted box, a thrust-bearing connecting the lower end of said arm. with the rear end of the driving-shaft, a shifting bar and connecting mechanism for moving1 the driving-disk away from the driven disk, or allowing the spring to act and bring the driving-disk into f notional contact with the driven 5 disk, substantially as set forth.

6. In a variable-speed counter-shaft, the combination, with supporting-hangers, of a driving-shaft mounted in suitable boxes in said hangers, a driving-disk at one end of said shaft, an arm pivoted to the rear hanger, a yielding spring engaging with said arm, a boss pivoted in said arm below its pivotal center, a thrust-bearing connecting said arm with, the opposite end of the driving-shaft, a toggle-joint having one end of one of its members located within a recess in the lower end of the pivoted arm, and the other member having one end located in a recess in the lower portion of the rear hanger, and a pivoted shifting bar having depressions at each side of its top end in which are located the two opposite ends of the toggle-joint bars, for moving the driving-shaft and its driving-disk away from the driven disk, substantially as described.

7. In a variable-speed counter-shaft, the combination, with a driving friction-disk, its driving-shaft and operating mechanism, of a supporting-frame, a slideway mounted thereto on, at right angles to the driving-shaft, a sliding carriage mounted on said slideway, a driven disk on said carriage facing the driving-disk at a slight angle thereto so that a portion of one side only is in contact therewith, two driving bevel-wheels on the driving shaft, a vertical shaft between said wheels, a beveled driven wheel and winding-drum mounted thereon, cords or cables connecting the winding-drum with the driven-disk carriage, and a pivoted shifting bar and its connecting mechanism, for moving the driven bevel-wheel to or in engagement with one or the other driving bevel-wheels, and thereby causing a movement of the driven disk the face of the driving-disk, substantially as set forth.

8. A variable-speed counter-shaft, consisting of a supporting-frame, a driving-disk capable of a rotary movement in its bearings, two bevel driving-wheels and a driving friction-disk mounted on said shaft, in combination with the supporting-frame, a transverse slideway, a carriage thereon, a driven friction-disk mounted in said carriage, at a slight incline to the working face of the driving disk, so that a portion only on one side of its center is in frictional contact therewith, a driven bevel-wheel, means connecting it with the driven friction-disks, a shifting bar, and means for bringing said driven bevel-wheel into engagement with one or the other bevel driving-wheels on the driving - shaft, and thereby causing a movement of the driven friction-disk on the face of the friction driving-disk, substantially as set forth.

9. In a variable-speed counter-shaft, the combination, with a depending supporting frame, of a driving-shaft mounted therein, capable of a longitudinal and a rotative movement in its bearings, a driving-disk rigidly secured to the forward end of said shaft, an arm pivoted to the rear frame-piece, a spring for moving said arm on its pivotal center in one direction, means for adjusting the force of said spring, a pivoted box, a thrust-bearing connecting the lower end of said arm with the rear end of the driving-shaft, and a shifting bar and connecting mechanism for moving the pivoted arm in an opposite direction against the force of said spring, and thereby operating the driving-disk, substantially as set forth.

10. In a variable-speed counter-shaft, a depending supporting-frame, a transverse slideway mounted on said, frame, a movable carriage mounted on said slideway carrying a driven disk mounted on a shaft so as to be capable of rotation, boxes on said carriage, in combination with a driving-disk rigidly secured to a driving-shaft set nearly at right angles to the driven-disk slideway and mounted in bearings in a depending frame, the driven disk being adapted for contact with a portion of its face on the driving-disk, means including bevel-gearings connected with and operated by the driving-shaft for moving the driven-disk carriage in its slideway and thereby moving the driven disk on the face of the driving-disk, a support for the shaft of one of said bevel-gears, mounted on the shaft of the driving-disk, and a shifting bar for bringing said bevel-gearing in to or out of engagement, substantially as set forth.

11. In a variable-speed counter-shaft, the combination, with the driven-disk carriage and slideway on which it travels, of a clamping device, a spring for closing the same and holding the carriage to the slideway at any point to which it may be adjusted, a carriage releasing bar and means for operating it and no opening the clamp and releasing the carriage, and moving the latter, substantially as set forth.

12. In a variable-speed counter-shaft, the combination with the driven-disk carriage and a slideway upon which it slides back and forth, of a pivoted clamping-bar and a closing spring for locking the driven-disk carriage when adjusted to the desired point, and means substantially as above described, whereby the driven-disk carriage is released just prior to being moved and instantly locked the moment the desired adjustment is made, substantially as set forth.

13. In a variable-speed counter-shaft, the combination, with a driven friction-disk, of a carriage upon which it is mounted on a rotatable shaft, and a track or slideway secured in a depending frame for said carriage to move on, a driving-shaft mounted at right angles to the carriage-slideway in boxes in a depending frame, and capable of a rotating and a longitudinal movement in its bearings, two bevel driving-pulleys mounted on the driving-shaft, a shaft mounted below the driving-shaft in boxes and capable of a longitudinal movement only in said boxes, an upright standard mounted: rigidly on said shaft, a vertical shaft journaled in said standards, a winding-drum and bevel-gears secured to said vertical shaft, ropes or cables connected with said winding-drum and with the driven-disk carriage, grooved friction-pulleys for keeping said ropes in position, and means for moving the driven bevel friction wheel from one to the other driving bevel wheels and thereby causing the movement of the :driven friction-disk across the face of the driving-disk, substantially as set forth.
