This paper presents examples in the application of the curve-matching method to four-bar linkage design problems: (1) a linkage to indicate flow through an orifice, (2) a linkage to linearize the flow characteristics of a butterfly-type valve, (3) a linkage to replace a cam and oscillating follower, and (4) a linkage to replace sector gears.
New computer-drawn displacement curves have been developed which provide a means of approximating transmission angles. Exact transmission angles are given in computer tabulations.

Two methods are presented for the analysis of errors caused by play in the revolute joints of a precision function generating linkage. The error occurring in the output angular displacement of a four-bar linkage is shown to be maximum for a given angular input when the vectors representing the clearances are parallel to the coupler. If the input variable is within a given range, maximum error occurs when the transmission properties are the worst. An approximate formula for the error is also given, which can be used for specifying clearances to keep the errors within permissible limits.
It is found to be very useful in the analysis to replace a joint with play by an imaginary link with ideal joints.

In the paper under consideration the authors synthesize an oscillating cylinder mechanism for the case when the first and second order transmission functions are given, without specifying the position in which these functions are to be assured. After completing the synthesis, that is, after determining the link lengths, the position is also found in which the imposed transmission functions hold. Graphs are here presented which enable us to readily find the parameter λ (representing the relation between the length of the frame and crank), when R′3 and R″3 are given.

This paper suggests a simple graphical method for finding the angular accelerations of the follower crank and coupler of a four-bar linkage. No velocity and acceleration polygons are required. The present method is complementary to a previous similar one, so that it is possible to analyse accelerations of any four-bar linkage by either method to yield quicker and more accurate results than the polygon methods. The present method is even more useful since it yields both the linear tangential acceleration of the flower crank pin and the relative tangential acceleration of this pin with respect to the driving crank pin simultaneously.

Problems of practical design of a mechanism are very often transformed into those of generation or approximation of a prescribed path or function. Such a formulation proves incorrect in some cases because it limits the variety of possible solutions. A computer allows application of optimum seeking methods in solving practical problems directly from design requirements.
