SPECIFICATION forming part of Letters Patent No. 754,992, dated March 22, 1904;.
Application filed March 26, 1903.
To all whom it may concern:
Be it known that I, CHARLES A. GRABNER, a citizen of the United States, residing at -Warsaw,- in the county of Kosciusko and State of Indiana, have invented certain new and useful Improvements in Exercising Apparatuses, of which the following is a specification.
This invention relates to an improvement in exercising apparatuses.
The object of the invention consists in providing means for varying the resistance to the pull, so that the apparatus may be expeditiously adjusted for a light, medium, or heavy pull, and thereby rendering the invention suitable for the exercise of children, women, and
Finally the object of the invention lies in providing an apparatus that will be strong, durable, efiicient, and one simple and comparatively inexpensive to manufacture.
With the above and other objects in view the invention consists in the novel details of construction and operation, a preferable embodiment of which is described in the specification and illustrated in the drawings, where- 1n- Figure 1 is a front elevation of the apparatus. Fig. 2 is a side elevation. Fig. 3 is a detail view of one of the double blocks. Fig. 4 is a detail view of one of the springs in end elevation and showing the couplingbar to which it is attached, and Fig. 5 is a side view of the coupling-bar. Fig. 6 is adetail view of the spring-suspending ring. Fig. 7 is a similar view of a modified form of ring.
In the drawings the numeral 1 designates a yoke formed of stout wire bent and twisted upon itself to form the ring 2 and the eyes 3. Rods 5, formed with eyes 6 at their ends, are suspended from the ring 2 and support at their outer or lower ends pulley-blocks 7 The eyes 3 of the yoke 2 support a pair of double pulley-blocks 8, and below the blocks 8 are provided another pair of double pulleyblocks 9. The blocks 7 8, and 9 may be of any suitable style and material and are provided with eyes or swivels 10, by which they are supported. A pair of elastic or non-elastic cords 11, each provided with a suitable handle 12, are threaded through the blocks, as follows: each cord being passed through one Serial No. 149,672. (No model.)
of the blocks 7 over the forward pulleys of the blocks 9, around the forward pulleys of the blocks 8, then down again and over the rear pulleys of the blocks 9, thence up over the rear pulleys of the blocks 8, and finally down to the blocks 9, where they are secured to the eyes 10. It will be readily seen that a very even movement of the cords over the pulleys is obtained, thus prolonging the life of the cords and relieving the apparatus of all movement of a jerky nature when manipulated by the operator.
As a means of varying the resistance oflfered to the handles 12 coiled springs 13 are provided. These springs 13 are formed with hooks 1 1 at each end, which are adapted to engage at their upper ends the eyes 15 of the blocks 9, and at their lower ends are hooked to the loops 16 of the coupling-bars 17 The coupling-bars 17 are provided with integral rings 18, which pass through the eyes 19 of the yoke 20. The yoke 20 is similar to the yoke'2, being formed with a ring 21,- adapted to engage one of the suspending-hooks 22. The hooks 14 of the springs 13 are of such a nature as to be readily disengaged from the eyes 15 and the loops 16, and thus any or all of the springs may be used. For instance, should a resistance be desired, such as to cause a strong pull to be exerted upon the handles 12, such as aman would require, all the springs are employed; but should a medium pull, such as a woman would use, be desired the central spring is removed, and thus the resistance reduced, and should a light pull, such as would be suitable for children be required, the two outer springs are removed, leaving only the central spring to resist the pull.
From the foregoing it will be evident that the pull and resistance may be varied by the use of any number of springs to suit the clifferent persons exercising with the apparatus.
For suspending the apparatus suitable hooks 22 for the upper and lower ends are provided, and it is to be understood that the apparatus may be used in the position, shown in the drawings or that it maybe inverted, so as to suit the positions and movements of the operator.
In Fig. 7 I have shown a slightly-modified form of the ring 15 for suspending the springs 13. It will be noticed that the ring 15 provides for the spacing of the spring-hooks 14, so that the springs may be placed in substantially parallel planes by substituting the modified ring 15' for the coupling-bars 17 and ring 15. (Shown in Figs. 1 and 6;) In this last form there is no liability on the part of the springs to bind or rub against each other.
The operation of the apparatus is very simple and will be quite evident from the foregoing description and the drawings. A pull exerted upon the handles 12 causes the cords 11 to run over the pulleys, thus drawing the blocks together against the tension of the springs 13, which resist the pull and which resistance increases with the length of the pull. When the pull is relaxed, the parts return to their normal position.
1 do not wish to limit myself to the exact details of construction and operation as herein set forth, as I may make various changes in the same without departing from the spirit of my invention.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In combination witha pair of oppositelydisposed yokes, pulleys carried by one of said yokes, coupling bars carried by the other yoke, a resilient connecting means attached to said bars, pulleys attached to the said resilient connecting means, cords passing over all of the said pulleys, rods carried by one of said yokes and having their free ends formed with eyes and means supported by said eyes through which the free endsof said cords pass.
2. An apparatus of the type set forth comprising a pair of yokes, formed with an intermediate and end eyes, a coupling means engaging the end eyes of one of said yokes, pulleys engaging the end eyes of the other yoke, intermediate pulleys, a resilient connection between said coupling means and intermediate pulleys, a pair of rods engaging the intermediate eye of one of said yokes, pulleys supported by said rods, cords passing over the first-named pulleys, intermediate pulleys, and last-named pulleys, substantially as described.
In testimony whereof I aflix my signature in presence of two witnesses.
