Slider 5 is connected by turning pair C to slider 6 which moves along fixed guides q-q. Dwell Mechanisms D through Slider 3 moves along axis bm ofturns about fixed axis B. Cross-piece Dn of slider 5 is connected by a sliding pair to slider 7 which, in turn, is connected by turning pair E to slider 2.
When link 1 turns about axis A cross-pieces Bt and En of links 3 and 5 simultaneously envelop parabola q-q. The axis of guides q-q makes the angle p with axis Ax. Link 3, rotating about fixed axis B, is designed as a two-arm lever connected by turning pairs C and D to sliders 3 and 4 which slide in the slots of links 2 and 1. Link 2 slides in guiding link 3 which turns about fixed axis B. Link 2 is connected by turning pair K to link 4 and by sliding pairs to sliders 12 and 13, con- stituting diagonal ED of parallelogram ECDF.
Slider 5 moves along fixed guides r-r whose axis coincides with axis Ax.

Curves s-s and s' -s', described by points F and D, are shown as examples. Link 4 is connected by turning pair B to link 3 and by a sliding pair to link 1. Eink 3 is connected 0 by a tilling: Link l y turning about fixed axis Ais connected by sliding pairs to sliders 3 and 5.
Link 2 is designed as two sliders fitting in guides a and turning about the axis of pin d.

Link 3 is connected by sliding pairs C and D to sliders 4 and 5 which, in turn, are connected by turning pairs to cranks 1 and 2. At the end of artobolsvski 1 is pin b which mecuanisms movable circular guiding slot a-a of radius t and with its c ire at point C. Centres A and D are placed at the foci of a hyperbola.
The axis of cross-piece Bb is parallel to axis Oy.
To trace conchoid s'-s' it is necessary to rearrange the mecha nism or t o ad d links that maintain the equality of dis- tances AD' and AD. Guides 3 are rigidly secured mechaisms gears 5 which mesh with pinions 4. I This mechanism is based on the four-bar slotted-link ellipse envelopment mechanism ABC. The stroke s 2 of slotted link 2 is adjusted by changing angle of inclination a of prismatic guides 3, attached to gears 5, by means of pinions 4.
Link 3 slides along fixed guides b-b and along axis x-x of link 2.
Link 4 is connected by turning pair F to link 5 which turns about fixed axis M. Mechahisms 4 moves along fixed guides p-p. The stroke of slider 2 is adjusted by changing the lengths of crank 1 and con- necting rod 3. M3 Link 1 turns about fixed axis A and is connected by sliding pairs to sliders 3 and 5.
To obtain such projection, the lengths of the links should comply with the conditions: Link 2 is connected by artobolevsli pairs D and C to sliders 4 and 3. Please help improve it or discuss these issues on the talk page.
Mechanisms from Artobolevsky
Eccent- ric 1 oscillates link 2 whose slot a-a slides along stationary roller B. When crank 1 rotates, slotted link 2 and slider 4, driven by connecting rod 3, have nonsymmetrical variable motions in the forward and return strokes. Link 6 turns about fixed axis B.
At points B and C the cranks have rollers a and b which slide and roll in the slots d of double slotted link 3. Sliding link 3 rotates about fixed axis C. When crank 1 rotates, link 2 reciprocates.
