' SPECIFICATION forming part of Letters Patent n8. 654,798, dated July 31, 1906;
' Applieatlen filed m 13, 1899. Serial No. 723,696. (NdmodeI-J To aZZ whom it may concern.-
Be it known that I, JOHN J. LEARY, a citi 5 New York, have invented certain new and useful Improvements in Reversing Mechaii ism, of which the following is a full, clear,
and exact description.
My invention relates to reversible friction- Io clutches, and more particularly to clutches used upon the divided shaft of a propeller and similar uses.
My invention has for its object means for driving, stopping, and reversing the propel- I 5 ler in connection with a driving-shaft which has a continuous rotation in one direction, and more particularly means for accomplishing these three operations which are at once simple and eificient.
While I do not wish to limit my invention to marine uses, it will be apparent to one skilled in the art that the above distinction is basic in marine construction and at once points out the vital requirements which I have met.
Referring to the drawings herewith, consisting of one sheet and two figures, in which like letters refer to like parts, Figure I is an end elevation with a portion cut away to show 0 the gear mechanism. Fig. II is "a longitudinal central section.
A is the driving-shaft, and B is the driven shaft.
0 is a friction-cone rigidly secured to the" 3 5 driven shaft B and provided with an external and internal conical bearing-surface.
D is a friction-sleeve splined to the shaft- A, as shown at g, which is free to move (within established limits) longitudinally upon the shaft A. The exterior conical surface of this sleeve D is provided with any desirable sur face to engage internally with the cone 0, as shown at a. p
E is a friction-sleeve which takes over the sleeve D and is free to move in rotation and axially within given limits. This frictionsleeve is in like manner provided with any desirable conical surface to engage internally with the friction-sleeve D, as shown at b.
F is a shell provided with an internal con- .ical surface to engage with the external surface of the friction-cone O, and this sleeve is also provided with an internal gear for the purposes hereinafter described.
G is a disk which takes freely over the sleeve E and is rigidly secured to the sleeve F, as
indicated by the screws 0'.
H is a spur-gear which is rigidly secured I to the sleeve E. In the drawings I have shown but one spur-gear J; butI preferably use two .or more.
I is a support with a central opening, through which the shaft A passes and which isproperly braced, as shown at e, and bolted or otherwise secured to a proper foundation.
To this support are revolubly secured spur gears J upon pivots f. These spur-gears mesh with the spur-gear H and the internal gear (I.
K andL are collars rigidly secured to the sleeve D by set-screws h and z. 70
M is a collar taking freely over the sleeve D and having an axial movement limited by the fixed collars K and L.
N is a lever pivoted at its foot and engaging with the collar M, by means of which the collar M is thrown into contact with the collar K or the collar L.
I 'Having thus indicated the several parts of .my device, I will now describe the, method of operation.
- The shaft A is driven continuously in one '1 direction by any suitable power.
Going ahead: By the lever N the collar M is thrown against the collar L, forcing the sleeve D into contactwith the cone 0, and
by friction imparts motion in rotation to the shaft B in the same direction with the shaft A. Thus in going ahead, which of course is the principal action, the driving and driven shafts are held up to action without other 0 friction in rotation than that necessarily arising from the thrust of the propeller.
Stopping: This operation consists in throwing the collar M in the opposite direction (to the left in Fig. 2) by the lever N and free- 5 ing the sleeve D from the cone 0.
Reversingi This operation consists in forcing the collar M against the collar K, drawing the sleeve D into frictional contact with r the sleeve E, which carries the spur-gear II. :00
Immediately the spur gear Hbeginstorotat'e in the same manner with the shaft A and meshing with the spear-gears J sets them in rotation in the opposite direction from the shaft A, and the spur-gearsJ meshing with the internal gear d the shell E is rotated in the 0p, posite directionfrom the shaft The gearing a'iid'- shell Fhowb'eing in motion, further pressure of the collar M against the collar K forces the inner face of the sleeve E against the face of thedisk G, which in turn carries the interior cone-surface of the shell F intone frictional contaetwiththe outercone-surface of the cone 0. Thus it will be seen that an initial motion is given to the reversing mech-' anism before the propeller-load is forced upon it, thus preventing shock to the gearing and strain upon the clutch.
Having thus described my invention, what I claim is V 1, In a reversible friction-clutch, a drivingshaft and a driven shaft having a common axis, a friction-cone rigidly secured to said driven shaft and provided with external and internal frictional surfaces for imparting motion to said driven shaft in opposite directions, a friction-sleeve secured in rotation with and movable axially upon said driving-shaft, a shell engaging frictionally with said fixed cone upon the driven shaft, a secondsleeve engaging frictionally with said sleeve on said driving-shaft, a disk' secured to said shell,
interposed gearing, and means for imparting axial movement to said sleeve held in rota tion with said driving-shaft, substantially as and for the purposes set forth.
2. A reversible friction-clutch, consisting of a driving and a driven-shaft and a cone secured to said driven shaft, providedwith a ern lan an inte ndwe lin -surf a sleeve splined to said driving-shaft provided witha face to engagewiththei'nternal surface of said cone;. a second sleeve taking over said sleeve splined to said driving-shaft and frictionally engageable with it, a spurgear on said second sleeve, a spur-gear meshing therewith and mounted on a fixed support, ahfexte'rnal shell provided with an in ternal gear meshing with said last-mentioned spur-gears and with an interior conical face to engage friction-ally with the external face of the cone upon the driven shaft, adisk secured to said shell, and means for throwing the several frictional contact-surfaces in and out of action through axial action imparted to the sleeve splined to the driving-shaft, substantially as and for the purposes set forth. 7 a r i In witness whereof I have hereunto set my hand, in the presence of two witnesses, this 23d day of June, 1899.
