MANUAL-TREINING APPARATUS. 4
Specification of Letters Patent. Patented Mar. 21, 1916.
Application filed April 2%, 1915, Serial No. 24,199. Renewed December 24, 1915; Serial No. 68,581.
To all whom it may concern:
Be it known that I, WILLIAM. J. HART- NETT, a citizen of the United States, residing at Austin, in the county of Travis and State of Texas, have invented certain new and useful Improvements in Manual-Training Apparatus, of which the following is a Specification.
TlllS lnventlon relates to new and useful.
improvements in a manual training apparatus.
The object of the invention is to provide a device of the character described which is specially designed for teaching the art of swimming and may also be used as a physi cal exerciser generally.
With the above and other objects in view, the invention has particular relation to cer tain novel features of construction, operation and arrangement ofparts, an example of Which is given in this specification and illustrated in the accompanying drawings, wherein:
Figure 1, is a side elevation of the device in use. Fig. 2, shows an enlarged Side/ 813. vation thereof, partially b-rokenaway. Fig. 3, shows an end view thereof, and, Figs. 4 to 8, inclusive, show. detached views of the operating parts. I
Referring now more particularly tot-he drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1, refers to the mat or body rest, composed of the frame -2, and
cushion 3, and which is mounted upon the tripod formed of the front legs 4, 4, and the rear leg 5. The upper ends of the legs 4, 4, are connected by the "arch '6, whose side is arcuate and sustains the front end of the frame 2, which is pivoted to the center thereof. The upper end of the leg 5, is pivoted to the rear part of the frame, 2, so
that the mat may have a limited lateral rocking motion and interposed between the arch 6, and frame 2, on each side, are the coil springs 7, 7, which serve as cushions and normally hold the mat level. U shaped levers 8, 8, are provided whose forward ends are pivoted to the rear end of the fra'me2, on each side and the free ends ofthe levers have the'flexible collars 9, 9, se-
cured thereto and provided to be strapped around the ankles of the learner,
Projecting forwardly from the legs 4, 4,
15, 15, and turn the be imparted through the shaft 11, the links 13, 13, and the levers 8, 8, to the lower links and fixed thereto are the brackets 10, 10,
pose later to be set forth. provided which has the wrists 12, 12, to which the forward ends of the respective links 13, 13, are pivoted and the rear ends of these links are pivoted to the corresponding levers 8, 8. The cranks 14, 14, are provided having inwardly turned ends which pass through the bearings of the brackets 10, 10 and are connected by universal joints to the respective ends of the shaft 11, and have the grips 15, 15, by means of which the cranks and shaft 11, are rotated.
uponthe mat wit-h the collars 9, 9, fastened around his ankles, and grasp the grips cranks. Motion will and these body movements will be very similar to the movements of the body in swimmmg; and by practlce, one will soon become accustomed to the movements which he must make'in swimming in water. The practice is also a healthful exercise in addition to acquiring the ability to swim. What I claim is: Y 1; A device of the character described including a body support, legs upon which the same is mounted, levers pivoted at one end to the support, "a shaft,-wrists carried thereby, links pivoted at one end to the wrists and at the other to the -means for rotating said shaft.
2. A device of the character described including a mat, supporting legs upon which the same is pivoted, so as to rock laterally,
levers pivoted at one end to the mat, a shaft,
wrists carried thereby, links pivoted. at one end to the wrists and at the other 'to the levers, and means for rotating said shaft.
rocklaterally, a pair of levers pivoted atone end to the mat end, collars carried by the free ends of the levers, ash fl; rgtatabl A shaft 11 is levers, and
The learner should lie, face downward I 3. A device of the character described in- I 2 1,176,365. v n v a mounted at the other end of the mat, Wrists name to this specification in the presenee of carried thereby, links pivoted at their .retwo subscribing witnesses.- vspective ends to said wrists and the corv responding levers and cranks connected by v v 5 universal joints toflthe respective ends of. W1tnes'ses:
