HAN D-OPERATED MOTOR.

SPCFCATION forming part of Letters Patent No. 654,986, datedJuly 31, 1900. Application filed November Z, 1899. Serial No. 737,573. (No model.) V

.To all whom, it may con/cern:

Be it known that LTnEoDoRE F. KRUEGER, a citizen of the UnitedStates of America, and a resident of NewYork,iiu the county and State of New York, have invented certain new and useful Improvements in Hand-Oper-A ated Motors, of which the following is a speciflcation. 1 j

This invention has reference to motors, and more particularly to liandoperated motors, in` which the rider by` means of a no vel mechani anism effects a continuous rotary motion and thereby locomotion.' l

The invention consistsespecially in a novel motor or driving mechanism characterizedV by a semilexible joint or connection forming part of the'movablelever through which the motion nof the vehicle is ini tiated.`V

It oonsists,'furth`er,in certain various novel vfeatures and in the arrangement and combil nation of the mechanical elementscomposing the motor. f 1 My new hand-operated motor is principally applied to tricycles and similar small and light:

vehicles which are used for outdoor pleasure trips. They are safe and convenient for chill dren and afford a great commodity during coni valescence. l

The invention is illustrated in the accom-` panying drawings, in which- Figure l is a view looking toward the rearV of the cycle fitted with a hand-motor embodyl ing my invention. Fig. 2 is a transverse sec tion of the same, aud Fig. Bis a detail view of certain portions of the motor or driving mechanism. b

Similar letters ot' reference denote like parts in all the drawings i f The drawings illustrate the bottom portion of the cycle. 'It is preferably a'tricycle3`but there may be any number of wheels as may be desired. I have shown two hand-'motors comprising suitable driving mechanism, one fitted to each oi' the large'driving-Wheels A -A, of which two'are shown." I will now proceed to describe one o f said motors or driving mechanisms, it being understood that the one shown onthe opposite side of the machine is a duplicate thereof-s B designates a lever loosely mountedlupon 5o the axle a of the driving-wheel A.

A' designates a pinion secured to rotate with the drive-wheel A.

C designates a spurgear loosely mounted on a stud-or pin o, secured to an uprising por-` 5 5 tion D'of the frame D. v f Eis a drivin g-pinion mounted upon a block l E-, which slides longitudinally inwiseiu the lever B.' rA spring b tends to pulltlie block iE' downwardly and retain the pinion-E in 6o "lever at the point f.

` ed, and hence adapted to rotatev Iwith same, is

a crank-disk G. This crank-disk carries a `wrist-pin g. The wrist-pin g engages with a slot h, arranged in the locking-bar I-I, as 75 shown. The lockinglbar `I-I isA mounted and arranged to slide in'suitable bearings b2 upon the lever B. I is a disk mounted upon the same stud upon which the pinion E is mountedand uponlthat'side OtftheIever'B as the 8o crank-disk G. The disk I has a plurality of pins or projections i, being'just about sufficientto receive the locking-bar H. The disk I being secured to the stud upon which is mounted .the pinion E is`of course arranged to rotate with same and when locked against rotation will prevent the rotationof the said pinion. i

f2-is`A aA spring which tends to return the handle F to its normal position after it has 9o been moved out of such position 4and released and to hold it in position against accidental displacement. i.

The above-described arrangement and construction of the handle F and the bar'B causes 95 the joint f to become a flexible connection. When the handle F-is grasped andi pulled in the direction of the arrow 1, the resistance in the direction of the arrow l will move the lever B in the direction of said arrow and by reason of the fact that the gear E is locked will cause the complete rotation in the direc-- tion of the arrow 2 of the spur-gear C. lThis will transmit motion in the direction of the arrow 3 to the pinion A', and the said pinion being fast upon the driving-wheel A will drive the said wheel forwardly in the direcf tion of the arrow 4. While the lever B is passing from the position shown in the drawings in Fig. 2 to the position illustrated by the dotted line X across the center line in said figure, the pinion E, consequent upon Athe differenceinl the arc described by the lever B from its center a and the top of the'spurgear C from its center c, will be given a mo-k tion longitudinally upon the bar B `against the tension of the spring 1). This motion does not interfere with the locking engagement of ythe bar H, the said bar being arranged to slide freely between the pins or projections/L- upon the disk I. When the lever has completed its stroke and is ready to return, the first movement on the opposite side of the arrrow, it will cause the handle F and the segment of the gear secured thereto to return to its normal position-and will withdraw the locking-bar H from between the pins and projections t' upon the disk I. This will free the pinion E,.and during the return movement of the lever B the said pinion will rotate freely, and the continued movement of the spufrQgear C inthe direction of the arrow 2, consequent upon the momentum of the drivewheel A-,will be permitted, fresh driving force being again exerted upon the said spur-gear upon following the movement of the lever B inthe direction of the arrow 1. The locking-bar His arranged, as shown, to move such a distance that it will clear the pins or projections t' upon the disk-I when out of-engagement therewith at any point-of movement longitudinal upon the lever of the pinion E. I c In the described manner a hand-operated motor or driving mechanism is produced which is simple and very eective and which `permits of the use of the most advantageous proportions in transmission-gearings.

, Having thus described my invention, I claim as new and desire to secure by Letters Patent-'- p1. A hand-operated motor composed of a pinion secured to the axle of the driving-Y contained in an uprising portion of the'frame and meshing the pinion, a lever with handle mounted loosely on the driving-axle, a driving-pinion mounted upon a block which slides longitudinally in ways in the lever, a spring below the block tending toretain the drivingpinion in mesh with the spur-gear, a disk mounted upon the stud of the driving-pinion provided with projections, and a driving-pinion-locking device cooperating with said projections, substantially as described.

, 2. In a hand-operated driving mechanism,

a lever mounted loosely upon the driving- 'aizle'and' provided'witli a semitlexible joint composed of a handle pivoted to the top of the lever, a spring below the handle tending to return same 'torits normalV position when released, a downward handle extension on the opposite sideot the pivot forming below a segment of gear-teeth,.a gear-pinion meshing with the toothed segment,a driving-pinion mounted upon a block which slides longitudinally in ways in the lever, a spur-gear meshing with the sliding pinion, a disk se cure on the stud of the sliding pinion'and provided with projections, a sliding-pinion locking device cooperating with said 4projections, and a connection between the gear-pinion and said locking device for operating the latter by the movement of the handle relative to the lever, as specified.
