App1ication filed February 7, 1910. Serial No. 542,519.

To all whom it may concern:

Be it known that we, Cosiio LIACI and ANGELO GIAMMATTEI, citizens of the United States-,residing at New .Haven, in the county 1 5 of New Haven and States of. Connecticut,

have invented a new and useful Means for Converting Motion, of. which is'a specification;

This invention has reference to improvements in means for converting motion and inent -whereby rotary motion may be converted into continuous rotary motion or .in-

termittentrotary motion differing from the speed andpower of the prime mover.

*" -The invention comprises a prime mover having a practically constant speed .and means' for converting the motion so gener- 2 0 power, and also into intermittent rotary moated intorotary motion of a different speedor speeds with commensurate available tion in different directions, and likewise provides-ineans for the storage ofpower until the accumulated poweribeoomes greater. than the power ofthe prime mover andlis then. utilized either rapidly, or slowly in accord-' aiice-with the workto' be performed.

The mechanism is reversible and therefore various types of motion maybe converted into continuous rotary motion.

- The invention will be best understood from aconsideration of the following detail description taken in connection with the accompanyiiig drawings forming a part of 'this specification, inwhich drawings Figures 1 and'2 taken together constitutea side elevation of the mechanism forming the subject matter of the present invention with some parts shown in section, the two figures over-lapping. together constitute a plan view of the mech- Figs. 3 and & taken anism shown in- Figs. 1 and 2, the two figures over-lapping. Fig. 5 is an end eleva- 4 foundation of proper construction,but which tion of the structure of Fig. 3.

Figs. 6 and 7 are detailviews of a clutch mechanism used in the structure. Figs. 8 and 9 are detail-views on a larger scale than in Figs. 1

and 3 of an inertia structure used in connection with the HIVQHUOIL' Fig. 10 is an elevation of a portion of a lever mechanism used in connection with the structure of.

Fi 1 f s b. I I q Referring to the drawings, there is shown a shaft 1 mounted in bearings upon suitable standards 2 which may be supported on a the following this block being sustained by a pivot'pin 6 so as to swing into and. out of the pocket as may be necessary, to overcome sudden resistance to the rotation of the fly wheel. The block 5 carries a spring? which when .the block is seated in its pocket 4: is under compression and tends to move the block outward around its pivot pin 6. Each block is formed with a cavity'S normally entered by one end 9 of a latch lever 10 mounted on the side oft-he rim of the fly wheel 3 and under the normal control of a spring 11 tending to'maintain the end 9 of the latch lever in the cavity 8 and so look the block 5 against movement about its pivot pin 6 under the action of centrifugal force.

At the end of the lever 10 remote from the end 9 there is a roller 12 designed to engage a fixed stop member 13 by which each lever 11 is carried in the rotation of the respective fly wheel or inertia member 3. The member 13 is carried by a post 'or standard 14 and is so disposed with reference to the respective fly wheel that when a lever 10 is moved past thestop member 13 the lever is turned on its pivot against the action of the spring 11 to an extent sufiioient' to withdraw the end 9 of the lever 10 from the cavity 8 and so release the block 5 to outward movement under centrifugal force and the initial impulse given by the spring 7. At another point in the movement of the fly wheel there is asecond stop member15 carrying an anti-friction roller 16 in position to engage the projected block 5 and turn the same on its pivot pin 6 to its seated position in the pocket 1 where itbecomes locked by the latch lever 10.

Mounted on the shaft 1 is a pulley 17 con nected by a belt 18 to another pulley 19 on ion 23 on the same shaft with a gear wheel 24 which in turn meshes with a pinion 25 on a shaft with a gear wheel 26 meshing with another pinion 27 on the same shaft with a gear Wheel 28 which in turn is in mesh with a gear wheel 29 on a shaft carrying another gear wheel 30, and the last 7 named gear wheel 30 is in mesh with a gear wheel 31 mounted on a shaft 32 having bearings in standards 33 erected on a suitable support which may be the same upon which the standards 2 are erected. The gear wheel 31 is in mesh with ,a gear wheel 34 on a shaft 35 mounted in hearings on standard 36, and the gear wheel 34 is in mesh with another gear wheel 37 in turn mounted on a shaft 38 having journal hearings in standards 39. The gear wheel 37 is in mesh with a gear wheel 40 mounted on a shaft 41 having journal bearings in' standards 42 and the gear wheel 40 is in mesh with another gear wheel 43 mounted on a shaft 44 having bearings in standards 45. Also the gear wheel 43 is in mesh with another gear wheel 46 mounted on a shaft 47 having hearings in standards 48. The gear wheel 46 is in turn in mesh with a pinion 49 mounted on a shaft 50 having bearings in standards 51 and also carrying fly wheels 52 against the rim of which there may be brought at will the active end of a brake lever 53. The pur pose of these several gear wheels will appear hereinafter.

Mounted on the shaft 32 on opposite sides of the gear wheel 31 are one- way clutches 54, 55, 56 and 57, best shown in Figs. 6 and 7 where it will be seen that each clutch comprises a casing 58 inclosing a ratchet wheel 59 fast on the shaft 32. In the inner wall of the casing 58 there is formed a cavity 60 housing a pawl 61 urged toward the ratchet wheel by springs 62. When the casing 58 is rotated in one direction the pawl 61 will ride idly over the teeth of the ratchet wheel and when the casing is rotated in the other direction the pawl 61 will engage a tooth of the ratchet wheel and the latter will participate in the rotary movement of the casing 58. The casing of each clutch 55 and 56 carries an arm 63 fast to the casing and having at its outer end a weight 64 which may be as heavy as desired and much larger in proportion than indicated in the drawings where the showing of the weight is simply typical or diagrammatic. The tendency of the weight 64 is to turn the casing 55 or 56 as the case may be in a direction to cause the rotation of the shaft 32. The weighted arm 63 is controlled by a lever 65 through a system of levers similar to a like system shown in- Fig. 2 and to be hereinafter described, and the lever 65 has its free end in the path of pins 66 on the hub of the gear wheel 34. Each time the gear wheel 34 rotates the two weighted arms 63 are elevated, the corresponding clutches 55 and 56 moving inactively. As soon as the pins 66 pass from engagement with the levers 65 the clutches 55 and 56 are released to the action of the weights 64 and a rotative movement will therefore be imparted to the shaft 32 through a distance agreeable with the movement of the weighted arms.

The two clutch members 54 and 57 have their casing provided each with an arm 67 projecting radially therefrom and at the free end pivoted to a post 68 rising from a head 69 lodged in a casing 70 containing a powerful spring 71. The head 67 is provided with anti-friction rollers 72 to ease its movement within the casing. The head 69 of each casing is provided with another standard or post 73 to which is pivoted a lever 74 at an intermediate point in the 'length of the latter, one end of the lever being pivotally secured to a fixed post or standard 75. The end of each lever 74 remote from its supporting post 75 is pivoted to another lever 76 which in turn is fulcrumed to a fixed post 77 while the other end of each lever 76 is in the path of radial arms 78 rotatable about the axis of the shaft 32, these arms being supported by said shaft but not secured thereto. The arms radiate from a hub 79 carrying at the end remote from the arms a worm wheel 80 engaged by a worm 81 on one end of a shaft 82 having journal bearings in a bracket 83 carried by a respective standard 33. It will be understood that there are two worm wheels 80 and worms 81 with their shafts 82 on opposite sides of the gear wheel 31. Each shaft 82 terminates in a bevel gear wheel 84 in mesh with a mutilated bevel gear Wheel 85 on the respective ends of a shaft 86 mounted in suitable bearings on the upper ends of standards 87. The shaft 86 carries a pulley 88 connected by a belt 89 to a pulley 90 on the shaft 1.

Power may be applied to the shaft 1 by means of a belt 91 traveling about a pulley 92 on the shaft 1 and coming from a pulley 93 on the armature shaft of an electric motor 94, but when the'power is applied to the other end of the structure then the motor 94 may be replaced by a dynamo from which electric current may be taken off.

Upon each shaft 38, 41, 44 and 47, there is a one-way clutch 95 with its casing provided with a radially extending arm 96 terminating in a weight 97 of suitable size though only diagrammatically indicated in the drawings. Each arm 96 is connected by a link 98 to one end of a lever 99 having a suitable fixed support while the other end of this lever is pivotally connected to another lever 100 having a fixed fulcrum support while the free end of the lever 100 is in the path of pins 101 on the hubs of the respective gear wheels 37, 40,43 and 46. When the gear wheels 37, 40, 43 and 46 are rotated then the pins 101 come into engagement with the respective levers 100 thus'rocking the levers 99 on their pivotal supports and elevating the respective weighted arms 96, the clutches then moving idly. As soon as the pins 101 move out of engagement with the levers 100, then the weights 97 become active to cause a rotative movement of the casings of the clutches 95. and this movement is transmitted through the ratchet wheels within the casings to the respective shaft- s 38, 41, 44 and 47 and rotative movement is imparted to the latter in a step-by-step manner, but because of the intermeshingof the gear wheels 37, 40, 43 and 46 the rotative movement of the shafts 38, 41, 44 and 47 will be in opposite directions one with relation to its neighboring shafts. If the motor 94 be energized rotative movement is imparted to the shaft 1 and to the fly wheels or inertia members 3 and movement will be imparted to the train of gear wheels 31, 34, 37, 40, 43 and 46 through the gear train 21 to 30 inclusive, the speeds of the gear wheels being proportionate to the relative sizes of the several transmission gear wheels. This will cause slow step-by-step rotative movement of the shafts 38, 41, 44 and 47 and these shafts may be connected to the work to be performed. At the same time rotative movement is imparted to the shaft 86 by the belt 89 and intermittent rotative movement is imparted to the shafts 82 by the mutilated gear wheels 85.

The showing of the drawings is in part diagrammatic, but it will be understood that the proportion of the mutilated gear wheels and of the gear wheels or pinions 84 as well as the worms 81 and worm gears 80 is such that the active portion of each mutilated gear wheel 85 will cause the movement of an arm 78 to an extent sufficient to compress the spring 71 through the lever systems 76 and 74 and then before the active movement of the mutilated gear wheel 85 ceases the lever 76 has escaped from an actuating arm 78 and then the spring 71 compressed by the active movement of an arm 78 is free to expand and so through the arm 67 and corresponding clutch 54 or 57 impart a rotative movement to the shaft 32.

The parts may be so proportioned that a strong impulse is imparted to the shaft 32 to cause its rotation in one direction by the expansion of one or both springs 71, depending upon the set of the mutilated gear wheels 85, and then the shaft 32 may be rotated in the opposite direction by the action of the clutches 55 and 56, and since the return movement of the shaft need perform little or no work, the said shaft 32 may be connected to work requiring a powerful movement in one direction and a comparatively weak movement in the other direction, and these movements of the shaft 32 will in no manner interfere with the continued though step-by-step forward movement of the shafts 38, 4'1, 44 and 47, though the rotative move ment of these last named shafts may be in reverse directions, but always in one direction so far as any individual one of said shafts 38, 41, 44 and 47 is concerned.

The present invention is useful in ma chines requiring various and complex movements for shaping or bending or both.
