1 UNITED STATES PATENT OFFICE JOHN HENRY BUGKLEY, OF MILLTOIVN, NEIV JERSEY.

CONE-G EARING.

SPECIFICATION forming part of Letters Patent No. 560,774, dated May 26, 1896. Application filed February 25, 18951. Serial No. 539,542. (N model.)

To all whom it may concern: Be it known that 1, Joan HENRY BUOKLEY, a citizen of the United States, and a resident of Milltown, county of Middlesex, and State of New Jersey, have invented certain new and useful Improvements in Cone-Gearings, of which the following is a specification, ref erence being had to the accompanying drawings, forming a part thereof, in Which similar numerals of reference indicate corresponding parts in all the figures.

The object of my invention is to provide an improved gearing for the transmission of power from an engine to a power-shaft or from a shaft directly geared or connected with an engine to a secondaryshaft, from which the power is transmitted to the machinery in the usual manner, whereby I may increase or diminish the speed of the secondary or power shaft at will; and the invention consists of what is generally denominated a cone-gearing, and in the construction shown and described the desired result is producedby a series of gear-wheels of different sizes arranged on adjacent shafts, the series of wheels on each shaft being so arranged as to present the appearance of a cone, the bases of which are in opposite directions, and means for locking the corresponding wheels on each shaft when desired and allowing the shaft to revolve within the others, all of which will appear in the following specification.

In the drawings forming part of this specification, Figure 1 represents a plan view of my improved gearing, Fig. 2, a vertical section on the line 00 so of Fig. l; and Fig. 3, a vertical section on the line y y of Fig. 2, looking in the direction of the arrow.

Referring to the drawings, the numeral 2 designates a shaft in connection. with aneugine or other rower-generator, (not shown,) and 3 a secondary or power shaft, from which power may be transmitted to machinery in the usual manner. In each of these shafts is formed a longitudinal groove or slot .4, in which is placed a lock or key 5, which is connected at one end with a collar 6, movably mounted on each of said shafts. Each of said collars is pr ovided with an annular peripheral groove 7, in. which is placed a divided clampring 8, to which are pivotally connected on opposite sides thereof arms or levers 9, secured at their other ends to a crankshaft 11, pivot a groove 13, (shown in Figs. 2 and 3,) which alines with the corresponding groove in the shaft 3 to receive the end of the key 5, which is secured therein, and twocollars or rings 14 are secured to each shaft at a predetermined distance from the center, one on each side thereof, which are designed to prevent the lateral movement of the gearwheels, which are placed between them.

A series of gear- wheels 15, 16, and 1.7 are arranged on the secondary or power shaft 3, as shown, decreasing in size in the order named and presenting the general appearance of a cone, and a corresponding series of gearwheels 18, 19, and 20 are arranged on the main or engine shaft, and which increase in size in the order named, and also present the appearance of a cone, the base of which is in a direction opposite to that of the cone first named. As shown in Fig. 2, the bore of each of these gear-wheels is provided with a groove 21,which corresponds with the groove 13 in the collar 6, and each of which alines with the groove 4 in said shafts when the gearwheels are in a position to admit of it.

' The key 5, the body of which is so formed asnot to project above the groove 4 when the keyis in position therein, is provided With a head 22, which projects above said groove and above the body of the shaft in which the groove is located, so as to project into the corresponding groove formed in the bore of the gear-wheels, as shown in Fig.2. It will be seen from this construction that by simply moving either of the collars 6 back or forth upon the rods 3 or 4 either of the gear-wheels located on said rods may be locked in its position and compelled to revolve with the respective shafts, It willalso be seen that when one of said gear-wheels is locked to the shaft and compelled to revolve therewith by means of said key each of L the other wheels will be independent of the lock and will revolve thereon; The key and its operating devices connected with the secondary or power shaft 3 are precisely the same as that connecied with shaft 2 and operate in the same manner, and the illustration thereof in section has not been deemed necessary.

The operation of this device is as follows: The engine or motor being in operation and it being desired to revolve the secondary or power shaft slowly, the collar 6 on shaft 2 is drawn backward until the head 22 of the key 5 enters the groove 21 in the gear-wheel 20, when said wheel will be locked to the shaft and revolve therewith. At the same time the key connected with shaft 3 is forced forward in the same manner by means of the collar 6 and its operative connections until the head on said key enters or meshes with the groove formed in the bore of the gearwheel 17. In this position of the lock the gear- wheels 17 and 20 are in operative connection with the shafts, and a comparatively slow motion will be transmitted to the powershaft 3. If now it is desired to increase the motion of the power-shaft 3, each of said keys will be drawn back until the heads thereof operate in connection with the grooves formed in the bores of the gear-wheels 16 and 10 to hold these gears in operative connection with the shafts. In this position and with these two wheels in operation the speed of the shafts would be substantially the same and the speed of the power-shaft greater than in the first instance. If now it is desired to still further increase the speed of the power shaft, the keys 5 are so operated as to secure the gear-wheels and 18 in operative connection with the shafts in the manner hereinbefore described, when the speed of the power-shaft 3 will be highly increased, and much greater, in fact, than with eitherof the former connections.

Though I have shown and described the key and its operative mechanism as connected with each of the shafts, it is evident that I may produce the same result by securing the wheels on one shaft rigidly thereto and have the key and its operative connections connected with the other shaft,'the wheels on said shaft being revolubly mounted thereon. As an illustration, the gear-wheels on the shaft 3 might be rigidly secured thereto in the usual manner, and those on shaft 2 revolubly mounted thereon, as shown, and pro vided with the key and its operative connections, as illustrated in Fig. 2. It is evident that with this arrangement exactly the same result may be produced as that herei'nbefore expense, and by an apparatus which is simple in construction and operation and not liable to get out of order, means for increasing or decreasing the speed of the powershaft at will, as the speed of said shaft may be controlled at all times by the number of gear-wheels employed and the differences in the diameters thereof, this being a matter that can be arranged or adjusted to any desired extent and within any reasonable limits. It is evident that many changes in and departures from the construction herein shown and described may be made without departing from the scope of my invention, and I do not limit myself to the exact form thereof herein shown; but,

Having fully described the same, its construction and operation, I claim, and desire to secure by Letters Patent, the following:

In a conical gearing, of the character described, the combination of' the main shaft provided with a longitudinal slot, a second shaft also having a longitudinal slot, a number of different-sized gear-wheels carried by said shafts and constructed to engage in pairs, and being provided with grooves corresponding to the slots in said shafts, keys provided with heads to enter said grooves and slots, a collar mounted upon each of said shafts to prevent the lateral movement of said gear-wheels, another collar upon each shaft having a central or peripheral groove and a divided clamp-rin g secured in said central groove, pivotal arms secured upon the opposite side of said ring, a crank-shaft connecting the ends of the arms, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 15th day of February, A. D. 1895.

JOHN HENRY BUCKLE Y.
