The typical mechanism is based on the induced centrifugal forces and it achieves to convert rotary motion to unidirectional motion. Extending from the guide member I2 there is a shaft I'I which is journaled in a bearing I8 provided in a housing I9 which encloses the crank mechanism. 11, 1950 Stdt?

Pre-electricity sewing machines often had a foot operated treadle that was used to drive a wheel. 82.? motors. These guide members are positioned opposite to each .other `and rotated about axes which extend substantially parallel .to each other and which can vbe spaced in non-coaxial relation to each other. It is achieved by connecting a slider and a crank with a rod. Another objectro the invention is. Stated more specifically linkages may be used to convert: Continuous rotation into continuous rotation, with a constant or variable angular velocity ratio. The mechanism may also include a rotary variable speed device which can be made to alternately accelerate and slow down the rotation of the guide members so as to vary the rate of travel of the reciprocating guided member in one direction from that in the other direction. III. April l 1, 950 J. R. HEFLER NEORANISM FOR CONVERTING ROTARY MOTION TO LINEAR REOIPROOATING MOTION 2 Sheets-Sheet l Filed July 4, 1945 INVENTOR J0 /2. In case of a constant angular velocity, we derived closed form analytical expressions for all mechanical quantities related to the motion of an object to which the inertial mechanism is attached. The easiest and simplest means of creating motion in a machine is to use a motor. This mechanism transmits the Reciprocating motion into rotary motion. The basic mechanism design is explained by using this mechanism. crank and slider mechanism title objective to obtain the displacement, velocity and acceleration diagram for the motion of crank and connecting rod assembly. The velocity oithespeeding upandslowing down may be varied" by changing the relative angularity between the` coupling. A collar 28 is secured to the shaft and engages against a shoulder 2I surrounding the bearing I8 and prevents lateral movement tending separation of the guide members. Since the crank pin is free to move relative to each guide member and is equally moved thereby, its center will assume a position at the center of intersection of the grooves I5 in all positions of rotation. Any application that requires a constant oscillation can have this design applied to it. VIn general the invention comprises a crank mechanism in which .twocranks are provided and which arehereinafter designated as guide members. This is due .to the fact-.that in a circleallinscribed anglessubtended by the same are are equal and therefore the locus of the apex of a xed angle between two points-will be :the arc of a circle connecting the two points. Pull the crank of this mechanism and you will see that it transfers rotary motion into translation. This in effect provides for the crank pin to be driven or moved equally by each guide member. 5 the plotting of the crank pin center as it will occur due to various positions of angu larity or rotation of guide members is illustrated. 6. This changes the eyes on the front of the card. In order to provide for overloads on the crank mechanism, the member 400. is connected to member 38 by means of a weak link device such as a shear pin 40e. The most common obvious one for the crank rocker in the automobile is the windshield wiper. It will be noted that for each half revolution of the guide members I2, i3 a complete revolution of crank pin center about its axis of revolution will be had. In Fig. Every application is specific and each design must be custom tailored to suite it’s needs, but the underlying basic design and function of these 4 bar linkages is the same. 4i A' mechanismjfor" converting rotary motion to'linear reciprocating motion comprising a link, a guidedmember attachedto' said link and reciprocated thereby, means for reciprocating said link including rotary guide members operatively connected to said link, one end portion of said link rotating in a path intersecting the axes of rotation of said guide members, a bearing movably mounted and in which one of said guide members is journalled, and means for moving said bearing for varying the axial spacing between said guide members for shifting the location of the axis about which said end portion of the link rotates.

Most engineers are faced with the task of designing a machine or device that accomplishes a specific function. A connecting rod, eccentric strap or other linkage is provided for operatively connecting the crank pin to a member guided for linear reciprocating motion, which may be straight line or curvilinear as desired. The angle formed at the center of intersection of the grooves I5 will be a fixed right angle at all positions of rotation. In the mechanism means are provided for moving the axes of rotation of the guide members in relation to each other so as to decrease or increase the throw of the crank pin by predetermined amounts. A knob 3l is secured to the member 28 for manually rotating the same. Each guide member is provided with a guide element I4 therein, which in the present instance is in the form of a groove I5 that extends diametrically across the face thereof, with the groove in one member positioned opposite and at substantially right angles to the groove in the opposite guide member. l AL mechanism for i convertingv rotary motion toi-linear:reciprocating motiony comprising a link', a guidedl member `attachedI tosaid` link and' reciprocated thereby; means for rotating one-end portion of saidi'link i'n a'circulary path., andi-means includingv anormally stationary member manue ally operableforshifting the axis about which said linkf'end'rotates.'.

For linear motion the general approach is to use a rack and pinion design, but for oscillating applications there are two specific designs that engineers use; the crank rocker or the crank slider. Therefore, in accordance with the geometrical fact that an angle inscribed in a semicircle is a right angle, the crank pin center will move in a circular path passing through the axes of the guide members I2, I3. A slider-crank mechanism is a typical design which converts rotary motion into linear motion. Rotary tools ripple through ruggedly as they spin at extremely high speeds. In Fig. 2 `is an elevational view partially insection or the crank mechanism .shown in Fig. Motion. The yoke has an elongated slot 80 through which the crank pin 14 extends and is also provided with oppositely extendingarms 8|, 82. Adjusting these can result in a power stroke in one direction that uses more of the power from the motor while the returning stroke uses less power. This is a critical design that is used extensively in automation systems where products are pushed and moved on a production line. The motor provides the crank and the wiper oscillates back and forth wiping water and debris from the wind shield. In the assumed position B and Cv will be coaxial to each other.
