EXERCISlNG-MACHINE.

SPECIFICATION forming part of Lettrs'latent No. 740,443, dated October 6, 1903.

Application filed August 7, 1901. Serial No. 71,140. No model.)

To all whom it may concern:

Be it known that I, J OHN CHARLES KORTH, a citizen of the United States, residing at Harrison, in the county of Westchester and State of New York, have invented certain new and useful Improvementsin Exercising-Machines, of which the following is a specification.

My invention relates to exercisers or exercising-machines; and its objects are to improve upon the construction of such machines and afiord greater facility for dilferent kinds of exercises with one machine.

f Further objects of my invention will hereinafter appear; and to these ends my invention consists in an exerciser for carrying out the above objects constructed and arranged and having the general mode of operation substantially as hereinafter fully described in this specification and shown in the accompanying drawings.

In the accompanying drawings, Figure'l is a view in elevation of the rear of an exerciser or an exercising-machine embodying my invention and showing in dotted lines a modified form of handle. Fig. 2 is a detail view, partly in section, of a form of detachable coupling 'embodiedin my invention. Fig. 3 is a detail view, partly in section, which is taken on the line 3 3 of Fig. 1. Fig. 4 is a detail view showing a modified form of exerciser, which may be made from parts of the exerciser or exercisingmachine shown in Fig. 1. Fig. 5 is a View showing a modified form of compressible handle. Fig. 6 is a viewshowing a modified form of support. Fig. 7 is a detail view of parts of Fig. 5.

Similar letters of reference designate corresponding parts in all of the forms.

A A represent two inelastic cords, though there may be only one such cord. One end of each cord is connected to a support a and the other end of each cord is connected to an elastic cord A Compressible handles 0 are connected to the other ends of the elastic cords A The inelastic cords A A intermediate their ends are passed about pulleys a Q The upper pulleys a are suspended from the support a, and the lower pulleys are detachably connected to main elastic'cords A The lower ends of the main elastic cords A are connected to a. support or supports B.

I The support a is here shown as consisting of wire, which is bent to have a suspending eye a and two other circular eyes a a the former being for the pulleys and the latter two eyes for the ends of the inelastic cords. Instead of this form of support the form of support 13 (shown in Fig. 6) may be employed. In this form the eyesa" a are omitted and the ends of-the wire joined together and one end provided with an eye b, to which the ends of the inelastic cords may be connected. This form of support also permits of a single inelastic cord being used instead of two inelastic cords A A. If a single inelastic cord is used, it is secured at its middle either to the eye 19 or to the two end portions b 22 The end portions of the single cord are then passed around the pulleys a a, as shown in Fig. 1.

In making the connection between the cords A A A A and handles or grips C detachable couplingsD in the form of snap-hooksare used. A preferable form of coupling'is illustrated in Fig. 2. As here shown, this coupling consists of a wire one end portion of which is wound in a spiral d to secure it to the end of an elastic or inelastic cord. The other end of the wire is bent to form a hook d, and working on the end of the hook is a cylindrical-cap (:3 which is pressed against the spiral portion at by a spring 01 Thus a closed eye is provided which will prevent any of the parts being accidentally disconnected from one another. In making connections between the several parts of the exerciser or exercising-machine a ring (1 may be employed, or eyes may be provided with which the couplings D may be connected. I preferably provide a ring d between the couplings D of the inelastic cords A A and the elastic cords A To one of the rings (1 I secure a detachable coupling d, which, as here shown, consists of a hook. This coupling 01 is for the purpose of connecting thetwo rings 01*. This serves as a connection between the ends of the two elastic cords A farthest away from the handles, so as to provide for exercises which will involve the stretching of these elastic cords at an angle to or in line with each other. The detachable couplings also permit of various changes being made in the grip c, to which the ends of the stirrup are detachably connected. The stirrup may be provided with a single eye a or with a plurality of eyes 0 as shown in dotted lines, Fig. 1, and full lines, Fig. 4. In case of providing the handles 0 with a plurality of eyes the elastic cords .A A may be disconnected from theother parts of the exerciser and connected to the two handles, as shown in Fig. 4. I preferably employ in connection with each handle 0 a compressible part 0 in the form of a hand-piece or grip. The two handpieces or grips c O are capable of rotating as a whole relatively to the stirrup. This provides for a wrist-exerciser or grip-developer which can be used in connection with the exerciser when the arm or hand isin any position. In the use of such a handle in connection with the machine of Fig. 1 the grip C may be left free and the handle used in the ordinary manner. The two grips c 0 may be connected with each other by a wire 0 the ends of which are inserted in the two grips c O and which is provided intermediate its ends with a spring-hinge in the form of a coil 0 having a tendency to separate the two grips c C away from each other. As will be seen from Figs. 1 and 3, the ends of the stirrup 0 may be disconnected from the grip 0'. One end of the grip is recessed to receive an end of the stirrup, and the other end of the stirrup may he provided with a yielding hook c to receive and support an end of the wire 0 which passes through. said hook and is inserted to agreater or less extent into the other end of the grip c, as shown in Fig. 3. This permits of the two grips c 0 being disconnected from the stirrup and used independently, or, if desired, the stirrup 0 may be disconnected from the elastic cord A and the two grips c 0 used independently. Since the Wire 0 may be inserted into the grip c to a greater or less extent, greater or less leverage may be obtained in compressing the grips O 0' together.'

Instead of the form of handle shown in Fig. 1 being used the handle E (shown in Fig. 5) may be substituted. In this form of handle a ]-bail part 6, to which the ends of the stirrup are connected, (see Fig. 7,) is carried by the grip c. The grip C is provided with eyes 6 at its ends, which eyes carry sleeves 6 through which the ends of the bail part c extend. Springs .6 are provided between the collars e and the collars e, which are fixed on the part c. This form of handle may be used independently of the exercising-machine.

It is obvious that various modifications and slight changes may be made without departing from the spirit of my invention.

What I claim as my invention is v 1. An elastic hand-grip for an exerciser comprising a stirrup, a rotatable grip forming part thereof, a second grip and a bent spring connecting one end of the grip with one end of the handle, leaving the other end of the grip free, whereby said grip may be rotated relatively to the handle about an axis transverse to its length.

2. An elastic hand-grip for an exerciser comprising a stirrup having a rotatable grip forming part thereof, a second grip and a bent spring connecting one of the ends of both of the grips, whereby both grips may be used together as an elastic hand-grip, or the rotatable stirrup-grip be used independently.

3. An elastic hand-grip for an exerciser, comprising a rotatable grip, forming part thereof, a second grip and a bent spring connecting one end of the grip with one end of thehandle, leaving the other end of the grip free, whereby said grip may be rotated relatively to the handle about an axis transverse to its length.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN CHARLES KORTH.
