Abstract
Abstract A self-training exercising device to develop the proper limb movement for swimming comprising a central box support and two triangularly shaped arm units, all of which enclose a geared wheel mechanism, chain drive and reduction gear linked by the chain drive to a horizontal bearing shaft, the user of the device placing his body on the box support and stretching his arms to the arm units. The user''s legs fit into reciprocating adjustable lever-supported foot rests which are attached to a horizontal shaft. The recirpocating leg levers and leg supports move alternately along vertical planes parallel to each other to provide the proper leg movement for crawl stroke and back stroke and the hand movements are carried out by movement of the arms which grasp a handle member moving along an elliptical track or guideway. A motor serves to drive the leg and arm levers.

Claim 1
Independent Claim
222 words
A self-training exercising device to develop the proper limb movements for swimming comprising: a housing means having a center portion to support a body and two side portions each to house an arm training means, each of said arm training means comprising a hand grip, means to move said hand grip in a generally elliptical path in a plane inclined to the vertical to thereby simulate the arm movements of a swimmer executing the crawl stroke, said means to move the hand grip in an elliptical paTh comprising a flexible, endless drive means trained over a series of wheels to shape the endless drive means in a general elliptical configuration, attaching means to secure the hand grip to said endless drive means, and a support plate for mounting said wheels, said support plate being so mounted in a plane inclined to the vertical and thereby cause the hand grip to move in a plane inclined to the vertical, two leg training means extending from the central portion of the housing and each carrying a stirrup means to be engaged by the feet of the user, power means and mechanical drive means connecting said power means to said means to move said hand grips and to said leg training means to oscilate the same to simulate the leg movement in a crawl stroke.
Claim 2
Dependent Claim

A self-training exercising device to develop the proper limb movements for swimming comprising: a housing means having a center portion to support a body and two side portions each to house an arm training means, each of said arm training means comprising a hand grip, means to move said hand grip in a generally elliptical path in a plane inclined to the vertical to thereby simulate the arm movements of a swimmer executing the crawl stroke, said means to move the hand grip in an elliptical paTh comprising a flexible, endless drive means trained over a series of wheels to shape the endless drive means in a general elliptical configuration, attaching means to secure the hand grip to said endless drive means, and a support plate for mounting said wheels, said support plate being so mounted in a plane inclined to the vertical and thereby cause the hand grip to move in a plane inclined to the vertical, two leg training means extending from the central portion of the housing and each carrying a stirrup means to be engaged by the feet of the user, power means and mechanical drive means connecting said power means to said means to move said hand grips and to said leg training means to oscilate the same to simulate the leg movement in a crawl stroke.
Claim 3
Dependent Claim
37 words
The device as set forth in claim 1, wherein the endless drive means is a sprocket chain and one of the wheels is of the sprocket type operatively connected to the power unit to be rotated thereby.
Claim 4
Dependent Claim
37 words
The device as set forth in claim 2, wherein the attaching means comprises elongated, relatively movable, interconnecting members whereby the overall distance between the hand grip and the sprocket chain is adjustable to fit various arm lengths.
Claim 5
Dependent Claim
58 words
The device as set forth in claim 3, wherein the elongated members comprise a sleeve member having an offset end secured to the flexible endless driving means and a rod telescoping within said sleeve, the rod carrying the hand grips and an elliptical trackway engaged by said offset end to guide the hand grips in an elliptical path.
Claim 6
Dependent Claim
75 words
The device as set forth in claim 4, wherein each of said leg training means comprises elongated, relatively movable, interlocking members to adjust the overall length of said leg training means, means pivoting said leg training means intermediate its ends, cam means engaging the end remote from the end carrying the stirrup means to oscilate said leg training means, and drive means connecting said power units to said cam means to rotate said cam means.
Claim 7
Dependent Claim
43 words
The device as set forth in claim 5, wherein said elongated members comprise a sleeve member mounted for pivoting movement and having one of its ends engaged by the cam means, and a rod member telescoping within said sleeve and carrying the stirrups.
