MECHANICAL MOVEMENT.

Speciicaton of Letters Patent.'l

Patented May 18, 1909.

Application filed March 25, 1908. Serial No. 423,119.

To all whom (it may concern:

Be it known that I, PHILIP T. MCNALLY, a citizen of the United States, residing at Mandan, in the `county of Morton and State of North Dakota, have invented a new and usei'ul Improvement in Mechanical Movements, olwhich the following is a specification.

My invention is in the nature of a novel mechanical movement, for converting simple reciprocating motion into a modified reciprocating motion alternately in two diiierent planes, for various uses in the arts, and it consists in the novel construction and arrangement of the stationary frame provided with guides for the reciprocating member, in combination with a shifting switch acting automatically to direct the movement, as will be hereinafter more fully described with reference to the drawing, in which- Figure l is a front view, and Fig. 2 an edge view oi' the mechanical movement.y Fig. 3 is a centralr longitudinal section, showing theA position oi parts for directing .the reciprocating body into one plane of actlon. Eig. 3a is a similar section, showing the position ol' parts for directing the reciprocating body Fig. 4 is a Fig. 5 is a longitudinal section o n line 5-5 of Fig. 1 and Fig. 6 is a sectional detail of the auto-k into another plane oi' action. cross section on line 1*4 of Fig. 1.

matic shifting switch.

In the drawing, A B B represent a stationary mainframe with its guides, O is the shift# ing switch, and E is the reciprocating member whose plane oi reciprocation is directed alternately into the two paths of the guide slots h and h.y v

The main frame is composed oi a central piece A made wedge-shaped at one end and supported exclusively at the other end by screws s s which connect it detachably between the two legs B B of the outer frame portion. l each side so as to form, between its sides and the outer frame, slots h h which at their lower ends converge and merge into the single guide slot r which preferably bisects the angle of convergence of the slots 71, and h equally, and, as shown, the slots h and h are parallel and the plane of the slot r is parallel to the slots 7L and h and if extended the plane of slot r would be equidistant from the slots h and h.

The central piece A is recessed on The shifting switch O consists of a triangular metal block inserted in a slot in the wedge shapedend of the piece A and pivotally connected thereto by a pin g. Within a recess in one apex oi' the switch block O is pivoted uponits pin g a symmetricallyiormed switch tongue c which is maintained normally in a line bisecting the apex of the switch by two yielding iingers a a, one on each side or the tongue and bearing against it in opposite directions. The upper ends of these yielding fingers are pivoted in the recess of the switch block and the two iingers are drawn together by the tension of an interposed spiral spring fi which through the fingers aa exerts an equal pressure upon opposite sides of the spring tongue c which holds it straight and true, but allows it to yield in either direction.

The switch block O is capable oi tilting on its center. g, so as to cause its two upper corners to alternately extend across the guide .slots 7L and 7L and partially blockade the same. When the uppercorner of the switch block lies across the guide slot h, as seen in E ig. 3 then the yielding switch ton ue c will be thrown across the other guide s ot h just at the point where the two slots h h converge into .the slot r. In like manner when the switch block is tilted inthe other direction, as in Fig. 3a, so that its other upper corner lies across sloty h, slot h will be olpened above and will be closed below by t e tongue c.

The two positions to which the switch block C may bethrown are maintained by a brake or yielding detent, consisting of an elastic cross-head y' mounted on the end of a yielding stem d, sliding longitudinally in a central hole in the iece A and forced downwardly by a spira spring u arranged behindV the stem. The upper corners of the switch block are. formed with notches n n and when the switch block is turned, it forces the spring cross-head y' and its stem d back until the rounded portionI of one end ofthe cross-head drops into Vanotch n and thus xes and holds thev switch block in the )osition to which it may be thrown, until1 forcibly made to change its position again. When sufficient force is applied to the switch block in the opposite direction its notch n, pressing back the rounded end of the cross-head, causes the stem d to yield backward and let the notch pass and as the switch goes to the limit of its shifting move=V and then in the other of two different planes.

Assuming that the pin` E is the reciprocating traveler whose pathis to be changed' first into one plane and then into another', when the pin E rises and the switch is in the position shown in Fig. 3, it finds the tongue c lying across the entrance to the slot h. The pin E therefore in rising passes into the slot h across which the right hand upper corner of the switch block is at this time lying. Said pin therefore strikes this corner of the switch block and tilts it and its yielding tongue into the dotted position in Fig. 3 and full line position of Fig. 3a. When the pin E descends it strikes the spring tongue c and, as this yields to the left, the in passes by the same and down into the s ot r. Now on the next ascent of the pin E it finds the switch in the position of Fig. 3el and as the pin rises its entrance to slot 7L is blocked by the spring tongue c and said pin is therefore compelled to pass up the other slot h. As it rises therein it finds the left hand corner of the switch block lying across the slot 7L', and, striking the same, shifts the switch on its center to the full line position of Fig. 3 again. lt will thus be seen that the simple reciprocation of pin E, as or part of a machine, causes it with my devices to alternately enter first one, and then the other of the two paths` h and' h. As shown these paths are parallel, but it is obvious that they need not be so, but may be extended in any divergent directionfrom the slot r. l

ln the vedges of the device are formed slots t. These aredesigned to give passage to any two lever ends, pins, or other parts to which it may be desired to transmit motion alternately. The ends of two such devices in such case simply protrude through the slots t into the ath of the reciprocating member E, which a ternately acts first upon the device on one side and then upon the de'- vice on the other side. To render this more clear, l. have shown in Fig.' 1, in dotted lines, a lever l fulcrumed in the middle and having at its ends pull rods 2 and 4 with iii-turned ends 3 and 5, which extend through the slots t into the path of the reciprocating member E, the ends 3 and 5 being alter= nately lifted by said membervE. My device may be advantageously applied to the operactuated by any prime mover ation of electric switches and in various -other arts` where an-A alternate action is desired.
