ALFRED ERNEST TERRY, OF REDIDITCH, ENGLAND.

PHYSICAL EXERCISER AND DEVELOPER.

SPECIFICATION forming part of Letters Patent No. 766,743, dated. August 2, 1904.

Application filed April 8, 1904. Serial No. 202,214. No modehl To a. whom it may concern.-

Be it known that I, ALFRED ERNEST TERRY, a subject of the King of Great Britain, residing at Novelty \Vorks, Redditch, in the county of llorcester, England, have invented certain new and useful Improvements in Physical Exercisers and Developers, of which the following is a specification.

My invention relates to improvements in physical exercisers and developers, and has for its primary object the combination and arrangement with such mechanism of involute, coiled, or the like spring or springs and drum or drums from which a cord or cords may be unwound against spring force. 1 attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a front view, and Fig. 2 a plan view, of an exerciser constructed according to this my invention. Fig. 3 is an enlarged sectional plan view of the invention on line A B, Fig. 1. Fig. sis a detail view of aguide-rod used in connection with the spring. Fig. 5 is a front view of the wire handle-frame,which attached to the spring-box arbor. Fig. 6 is an end view of said handle-frame. Fig. 7 is a front view, and Fig. 8 an end view, of the wire guard for handle-frame. Fig. 9 shows a modified arrangement of this my invention in which the one handle may be secured to a fixture, while the spring drum or drums may be exercised by means of the other handles in the ordinary manner. Fig. 10 shows a further modification, explaining how two drums may be used instead of one, Fig. 11 being a side view of the device shown in Fig. 10.

Similar numbers refer throughout the several views to the same thing or part.

15 is a hollow drum within which is carried the spring 16. This drum may be made in any convenient manner, the method shown being very suitable for the purpose, which may be briefly described as follows:

17 is a short cylindrical barrel upon which are passed tightly the two annular flanges 18 and 19. The outer edges of the drum are now bent slightly outward. The two side plates 20 and 21 are now stamped out with a suitable hole at their center to accommodate the arbor or other parts, and, further, with theirouter edges 22 prepared to pass over the outwardlyturned edges of the drum, such edges 22 being then turned or rolled over the edges of the drum, so as to complete the general construction.

23 is the arbor to which one end of the spring 16 is secured, the other end of the said spring being secured to the cylindrical part 17 of the drum in the well-known manner of applying such boxed springs. Upon the arbor 23 is secured the ratchet-wheel 24, with which engages the ratchet-pawl 25, the said ratchet-pawl lever being carried in the bracket 26, which is partly carried upon the arbor 23 and upon the wire handle-frame 27, so that the said lever-bracket is rigidly connected to the said frame 27 28 28 are flexible cords whose one end is secured to the periphery of the drum, the said cords being wound around the drum, their other ends being connected up to the handle-frame 29.

30 is a guide-pulley, which is carried upon the arm 27 which is formed by an extension of the frame 29. 31 is also a guide-pulley, carried upon the swinging frame 32, carried from the arm 27, so that the cords are kept in order between the two pulleys 30 and 31.

33 and 34 are handles, carried upon the frames 27 and 29, respectively.

Referring to the arbor 23, it will be seen that when the pawl-lever 25 is in engagement with the ratchet 24 the said arbor is non-rotatable, or, in other words, it is fixed, as it were, to the handle-frame 27. Consequently if the handle 34: is drawn outward, the cords are drawn off the drum 15 against the pressure of the spring 16, the said spring force rewinding the cords upon the drum when the handle 34 is relaxed. In this manner the device serves as a physical exerciser or muscledeveloper.

Referring again to the arbor 23, it will be readily seen that by applying a spanner to the nut 35 the spring 16 may be wound up, so as to increase its force when a stronger pull is desired, and also, on the other hand, when it is desired to weaken the said pull the spindle 23 is moved forward slightly until the pawl 25 may be released, when under the controlling power of the spanner upon the nut the arbor 23 may be permitted to unwind itself to the extent desired, when the pawl 25 is again made to engage with the ratchet 24.

36 is a wire guard, one of which I place upon each side of the spring 16, with its ends secured into the cylindrical part 17, for the purpose of preventing the edges of the spring grating against the sides of the drum, and thereby causing an unpleasant noise and undue friction.

Referring to the handle-frame 27, this is made from a continuous piece of wire, having eyes 37 formed thereon for connection to the arbor 23 and permitting rotative movement of the said arbor therein.

38 is a wire guard, having eyes 39 formed at each end, which take onto the arbor 23 and which is bent to and fro, so as to embrace the frame 37 at 38 and 38 at which points the said wire is nipped tightly upon the frame 27, and thereby a very rigid combined frame and guard is produced.

Referring to Fig. 9, it will be seen that by means of the combination with the frame 27 of the connector 41, having hooks at 42, which take onto the frame 27 each side of the handle 33, and having, further, a loop 43, connected to the swivel 44, which said swivel may be looped onto a fixed hook or the like upon any fixed structure. I also provide an extra handle at 34 with frame 39 and detach the hook from the frame 39 and connect it to the frame 39*, thereby affording a separate handle for each hand of the operator.

Referring to Figs. 10 and 11, it will be clearly seen how readily multiple drums, each having its own spring and cord or cords, may

be adopted, if desired, such drums 46 and 47 being preferably placed side by side (although they may be otherwise disposed) and carried in a suitable frame 48, to which the arbor 23* is rigidly secured. The ratchet-wheel and pawl device may of course be applied to this arrangement, if desired.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a physical exerciser the combination of a spring-drum, one end of whose spring is connected to said drum, and its other end connected by suitable means to handle-frame, a cord or cords secured to said drum and wound thereon, and with handle attachment at the outer end of said cord or cords, substantially as set forth and shown upon the drawings.

2. In physical exercisers the combination of a drum, a spring connected to said drum and to the arbor of said drum, a handle and its frame connected to said arbor, said arbor having ratchet-wheel 24 secured thereon, and a pawl-lever 25 carried from the handle-frame, the said drum having flexible cord attached thereto, and a handle attached to said cord, all substantially as set forth and shown, and for the purposes Specified.

3. In physical exercisers the combination of spring-drum, pulling-cords connected to said drum, a handle attached to said cords, handleframe 27 fixedly secured to spring-arbor, and

suitable means for securing said frame to a fixture, as set forth and shown.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ALFRED ERNEST TERRY. Witnesses:
