    • 436,269. Exercising - apparatus. TOLCHIN, J. M., 150, Riverside Drive, New York, U.S,A. Feb. 2, 1935, No. 3481. Convention date, Feb. 5, 1934. [Class 132 (i)] An abdominal exerciser comprises an element on which the user kneels secured to a guide in which a handle is slidably mounted, the user moving from a crouching to an extended position in reciprocating the handle which is preferably biassed by means tending to restore the handle to the inner (crouching) position. The user kneels on pads 16 fixed to a base plate 12 secured to a casing 14 housing a slidable handle-bar 24 ending in handles 28. The bar 24 is rigid with a trolley 22, rollers 20 and 42 on which coact respectively with a guide rail 18 and groove 40 in the casing and a light compression spring 30 mounted on a rod 34, which in an alternative construction, may comprise the sole guiding means, assists return of the trolley to the inner end of the casing. The plate 12 may be angularly adjusted relative to the casing 14 by means of a screw 50 so that the user may exercise each side of his body separately. A pointer 56 and scale 54 indicate this adjustment and a further scale 58 indicates the movement of the handle-bar 24. A tension spring may be used instead of the spring 30 to return the trolley.
