- .'Be itknown that I, LEMUEL S. Frrnmrr, of theftown'of East'New York, county of Kings, and State of "New York, have invented new and useful Improvements in a Device for Communicating and Multiplying Revo- '1ntions'.;lround an Axis and I do hereby declare the followingto he a full, clear, and exact description thereof, which'willenahle' others skilled in the art to make and use the same, reference being bad to the accompanying plate of drawings, as forming apart of this specification. I 7 QflThe inventionfor which I desire to secure Letters Patent consists of anew and novel arren'gementof parts, whereby the velocity of rotation on a shaft can he more rapidly increased or decreased, and with'greater'economy; of space and power than with the ordinary combination of cogged wheels; i 7
r Thefdev'ice consists of a hollow cylinder, at reversing-wheel, a shaft, a. seriesof multiplying ivhels, and a .series of: intermediatewheels, with a. stand orframe, which supports the shaft.
,In the accompanying plate of drawings my improvements are illustrated.
Fignre I is a section of 'the device, .talrerithrough the axis of the shaft,
' Figure II-is an interior view of one end of the cylinder, showing the mechanismof the parts, wherebv the cylinder v is given a reverse rotation.
* j -f.- Fignre III shows the arrangement oftheintermediate wheels. e Y I The: hollow cylinder, 0. O, is provided with a partition, 0 0, nearone extremity, by means of which it is held in place on the shaft S S, whose axis is coincident withits axis. The concave or interior surface of the cylinder iscogged on both sides of the partition, the cogs extending parallel with'the axis of thefcylinder;
, -A coigged wheel, is attached to the axis.-. The diameter of this wheel is a little less thanthat of the cylin'deiy'the spacebetween the two being occupied by an intermediate wheel, 6, whose cogs mesh with those of R andC, onopposite sides. The direct revolutio n'of the wheel R gives the cylinder a reverse motion, whiohis" equal to the ratio of the interiordiameter' of the cylinder to the diameter of the reversing-wheel. 4.
0n the opposite side of the partition, a lever, L, isattached to the shaft. This lever carries at its outer extremity an intermediatewheel, P,"whose c'ogs mesh with those of the cylinder, and those of a multiplying: wheel, D, thelatter turning freely on the shaft S. '.To.th'e mnltiplyingwheel D, an arm is attached that carries an intermediate wheel, P. V The cogs of P mesh with those-of the cylinder, and those of the wheel E. Alever or armof carries-an intermediate"wheel, 'P' whose cogs mesh with those ofa third multiplying-wheel, F, and those of the cylinder.
The intermediate wheclsb, P, P, and P revolve in straps or clasps, g, and on rivets, whose ends are firmly held or secured by the straps, and for thelatter purpose'the straps are made to enclose the intermediates.
B is a stand or support, through which the shafts passes, and which also-secures the intermediate wheel 6; From the description-given, it must be evident that, if the shaft carrying. the reversing-wheel R and the lever L be-revolved in either direction, the hollow cylinder 0 C will be made to revolve in the opposite direc= tion with a velocity'whieh will bear the ratio tothe velocity of the shaft of the coggeddiameter of the reversing wheel It to the interior diameter of O, and that the wheel D will revolve with avelocity due to the direct velocity of L, the reverse velocity of C, and'the ratio of the diameter ,of' the wheel D to the interior diameter of the cylinder 0. 1 I In the drawings herewith submitted, t he diameter of the wheel Bis onehalf of that of the cylinder G, and
therefore, for each direct revolution of the shaft, the cylinder will make one-half of arevolution in the opposite direction. The diameters of the multiplying-wheels D, E, and F are one-half of the diameter of the-cylinder. The wheel D revolves four times, the wheel E thirteen times, and the wheel]? forty times, for each revolution of the shaft. By comparinggthese numbers, the law of increase of velocity of rotation will. be evident, vii,
the velocityof any wheel is equal to unity increased by three times the velocity of the multiplying-wheel next preceding. I 1 I 'By' increasing the ratio of the interior diameter of the cylinder to the diameter of the reversing-wheel'lt,
the reverse motion ofB will be correspondingly increased; as also the direct motion of D, E, and F. The cyl incler C may be given a rversovelocity great-er than the direct velocity of the shaft, by so a rranging the inter, mediate, I), that it shall mesh with a circle of cogs on the wheel R, larger than the'circle of cogs on C. with which it meshes. This may be done in any one of several obvious ways. t to By increasing the ratio of the diameter ofthe cylinder to the diameters of themultiplying-wheels l) E, and F, a. furtherincrenso of velocity may be obtained without increasing the number of wheels.
I do not intend to limit myself to t he mtios herein given, nor to the number of wheels explained above.
I claim as new, and desire to secure by Letters Patent, asfollows, viz-z I 1. I claim the combination of the reversing-wheel R, partitioned, revolving cylinder Cnvith one or more sets of m iltiplyiiig" and intcrmoili'nte wheels D and P, with'stro p s, g y, when combined"substantilillyas herein set fortli. w
2. I claim the straps g, g, g, and g, and their equivalents, when employed to sustain and strengthen ,the ends of the axes on whiehthe intenn'edinte wheels P, P, and P revolve.
3. I Claim the reversible hollow' cylinder 0, by moons of one or more wheels, R and b, one having an axis coincident with the axis of the shaft, and the other or others parallel therewith.
