Specification of Letters Patent.
Pa nted J an 65 192 -v Applicationfilediuly 12, 191-9. 'Seria1JNc.'310,33,3.
To all whom it may concern:
Be it known that I, ToNJEs A. Born, a citizen of the United States, residing at StratforcL-county of Fairlield,- State of Connecticut, have invented an Improveme lt in Mechanical Movements, of which the following is a specification.
This invention has for its-object to provide a mechanical movement adapted for general use wherever it is required to'utilize either the constant or intermittent rotation or. oscillation of a shaftin producing corintermittent reciprocatory rotation of the shaft producing a movement 1n one dlrectlon of the reciprocating member, the essential feature being that no reciprocatory'movement takes place until a quarterrotation, more orless, has been imparted to the shaft, and that said movement is then made with aquick snap, the completion of the half rotation of the shaft being an idle movement. This movement is applicable to various uses rasin valve mechanisms, and in .making and breaking the circuit in electrical devices. It is immaterial so' 'farcasathe principle of the inventionis concerned whether the partsare so constructed and arranged that the shaft rlS adapted to rotate continuously (in either direction, 1 sin .one direction only, or to 0501113138.
With the; above stated and :other objects in:view, I have devised the novel mechanical movement which I will now describe referring-to the accompanying -,drawing forming a partof this specification and usmgreference charcters to indicate the several parts.
Fi ure ;1 -;is an elevation of my 6 novel Fig-2a section on the-line2 -2 in Fig.
1, looking in the'direction of the arrows, the spring being partly broken away;
Figs/3, 4, 5, '6 and 7 sections; on the same line illustrating;dilferentpositions of parts,
and
;F ig. 8 is-a perspective view of the actuating member, detached.
l0 denotes the shaft which is provided with-a doublecrank 11. The shaft isjournaled in a suitable frame, indicatedby '12,
which may .of coursebe of ,anyrequired construction, the crank lying between arms or branches of theframe. '13 denotes a rocker which is [pivoted between the v arms ofv the fir men-ad se f omp ise a m ying il opposite s des of the crank and eachvprovided w th ,a circular opening l4: through which the shaft passes; Th Special construction of the rocker is 'unimportantso far as the principle of the nvention is concerned. I have shown the arms of the rocker as connected at their pivot ends.
a better balanced construction. One-Term may, however, be dispensed with and a one armed rocker used, if preferred.
Lying between the arms of the rocker is an actuating member which comprises a head 15, arms 16;and shoes 17 --whi ch are adapted to travel around the wallsof the circular openings in thearms of thetrocker. Lying between the arms of' the ;actuating member" is a coilspring 20, "one end 'ofwhich bears against head 15 and the othen-against the pin 18 of the double crank, which lies between the free ends ofarms l-6. V
Each half rotation of the shaft causes the crank pin to carry the actuating member around with it, the crank pin at the same time moving inwardbetween arms 16 and compressing the spring, andthen outward again whenthe tension of the spring isra lieved, the shoes meanwhile travelingaround the circular ivvalls; which bound the openings in the arms of the rocker. Y
. The specialconriections. by which the :os-
cillations of the rocker are utilized in p'rothe invention isconcerned. Inthe present instance I have indicated that the connection may be made by means of aforkedlink 19 connected to the arms of the rocker.
, The operation is asfollows: The invention is equally operative if the shaft .is rotated clockwise, or}counter clockwise, or oscillated starting witha ,clockwise, .or .a coun-ten clockwise movement. tarting with. the partsin the positionishown in Figs. ,1 and 2, I will describeithe, operation ,when the shaft is rotated continuously ,in the clockwise direction. v In Fig. ,8 ,the parts areon the dead center, the pivotal point I of the rocker, the axis of the ,spring and the crank p in being in alinement, and flthe spring fully compressed by the inward movement of the crank pin between the arms of the actuating member. An instant later the dead center will have been passed, the tension on the spring relieved, and the spring will instantly throw the parts to the position shown in Fig. 5, the position in Fig. 4 being an'intermediate position showing the spring expanding and forcing the crank pin outward between the arms of the actuating member. In practice the movement from the position in Fig. 3 to that in Fig. 5 is instantaneous, the spring causing the actuating member, and with it the rocker, to jump ahead of the shaft with a snap, and the last quarter rotation, more orless, of the shaft being an idle movement. Continuing the movement of the shaft, Fig. 6 shows a position of the parts an instant after the dead center has been passed the second time, the spring'being at its fullest compression and about to expand, the movement of the rocker not having commenced.
Fig. 7 shows an intermediate position of the parts, in other words, a position of the parts in the second half rotation cor responding with the position in the first half rotation shown in Fig. 4. An instant later the parts will be in the position shown in Fig. 2, a rotation of the shaft having been completed, and a complete reciprocation of the rocker having been produced. The throw of the rocker is determined by the size of the opening or openings in the rocker through which the shaft passes, alternate opposite sides of the walls of the openings contacting with the shaft after the movements. These movements are con- 'tinuously repeated, each rotation of the shaft producing a complete reciprocation of the rocker and the movement of the rocker in each direction being made with a snap, jump or kick through the expansion of the spring the instant the parts have passed the dead center. Incidentally it may be noted that while the compression of the spring is the same in the first portion of each half rotation of the shaft the full compression of the spring is reached and the parts are at their dead center slightly earlier when the crank pin is approaching the pivotal point of the rocker i. e. in the second half rotation of the shaft, than when the crank pin is moving away from the pivotal point of the rocker. This, however,
7 is wholly immaterial so far as the principle of the invention is concerned.
Suppose now that the shaft is oscillated making half rotations in each direction and starting in the clockwise direction. The movement, as shown in Figs. 3 and 4, to
the position in Fig. 5, would be as before,
and on the return movement the movement would be as shown in Figs. 4 and 3 to that shown in Fig. 2. This half rotation of the shaft and back to its starting position would have produced a complete reciprocation of the actuating member as before.
Should the shaft be rotating counterclockwise, the movement would be from the 70 position shown in Fig. 2 through the positions shown in Figs. 7, 6, 5, 4E and 3 to that in F ig. 2. I i
Should the movement of the shaft be oscillatory starting in the counter-clockwise direction the movement would be from Fig.
2 through F i s.- 7 and 6 to that in Fig. 5 and then bac (ward through the positions shown in Figs. 6 and 7 to the positionin Fig. 2.

A mechanical movement comprising a rocker pivoted at one end andprovided with a circular opening, an actuating member consistingof a shoe which engages said opening, a head and arms, a crank having a pin lying between the arms, and a spring bearing against the head and the crank pin, movement of the crank causing the shoe to travel around the opening without imparting movement to the rocker, and causing the crank pin to move inward between the arms and compress the spring until the parts are on a dead center, continued movement of the crank causing the spring to expand instantly and the actuating member to throw the rocker to the extreme of its movement with a snap.
