WILLIAM C. BLACK, OF CHICAGO, ILLINOIS.
SPECIFICATION forming part of Letters Patent No. 674,431, dated May 21, 1901.
Application filed August 27, 1900. Serial No. 28,121. klNlo model.)
To all whom it may concern:
Be it known that I, WILLIAM C. BLACK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and usefulImprovement in Skipping-Ropes, of which the following is a specification.
This inventionrelates to skipping-ropes.
One object of the invention is to provide a skippingrope which is of simple construction and arrangement wherein when not in use the rope or skipping part is coiled up and incased in compact condition.
A further object is to provide a construction and arrangement wherein the rope or.
skipping partmay be adj ustably extended to any desired length.
Other objects of the invention will appear more fully hereinafter.
The invention consists, substantially, in the construction, combination, location, and arrangement, all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claims.
Referring to the accompanying drawings, and to the various views and reference-signs appearing thereon, Figure lis a View in central longitudinal section of a construction embodying the principles of my invention, showing the several parts in assembled relation, with the skipping-rope inclosed within its containing casing. Fig. 2 is a sectional view on the line 2 2, Fig. l, looking 'in the direction of the arrows and showing the reelratchet in engagement with the tooth on the casing. Fig. 3 is a View similar to Fig. 2, showing the reel-ratchet disengaged from the tooth on the casing. Fig. Il is a face or side view showing the reel-operating spring and manner of connecting the same. Fig. 5 is a sectional detail View of the interior of the handle or coiling-chamber oi' the casing, showing the tooth or detent. Fig. 6 is a detached detail view in perspective of the reel.
The same part is designated by the same reference-sign wherever it occurs.
In the drawings, reference-sign A designates an open-ended tube, vwhich when the parts arev assembled as shown in Fig. 1 constitutes a portion of the inclosing casing. Arranged within tube A is a second tube B of somewhat shorter length, as clearly shown, and of an external diameter adapting it to be inserted longitudinally into tube A and to be held therein by frictional contact with the inner surface of said tube A.
Referencesign C, Fig. l, designates the handles of the skipping-rope,whi ch are in the form of hollow casings and, if desired, may be of any suitable or convenient shape. In the particular form shown these handles are of spherical shape and are composed of the sections D E, each of which is hollow and of semispherical shape, said sections being suitably formed on their meeting edges to be assembled and held together to form a complete inclosure. Each section D E has formed therewith or is otherwise suitably provided with an extension F, which when said sections are assembled cooperate together to form a short tubular extension, as clearly shown in Fig. 1, and these tubular extensions are of such external diameter as to be snugly received in the open ends of the tubes A and B, respectively. Thus the extension of the one handle is received in the end of tube A and the extension of the other handle is receivedin the opposite end of tube B, as clearly shown. By this construction it will be seen that by grasping the handles C and exerting a pull thereon in a direction to separate the same the tube B will remain attached to the extension of one of the handles and will be withdrawn from tube A, While said tube A will remain attached to the extension of the other handle, thus affording ample and convenient hand-grips in the manipulation of the skipping-rope, and by telescoping the tube B into tube A or the tube A upon tube B the parts are again assembled in compact form.
In each handle or casing' C is mounted a reel to which are secured the respective ends of the skipping-rope G, and in carrying out my invention I provide each reel with'an operating-spring Linder the power or in Iiuence of which the skipping-rope is normally wound up or coiled upon said reels, and in connection with each reel and operating spring I provide a detachable detent or ratchet mechanism by which the reel may be held at any desired unwound position against the normal tendency of the operating-spring to wind or turn and maintain the reel in the IOO Vopposite direction.
Many specifically different constructions for effecting these results may be employed. While, therefore, I have shown and will now describe one construction which I have found simple and efficient for the purpose, I do not desire to be Vlimited or restricted thereto. As the construction and arrangement in each handle is identical, the description of one Will suffice for both.
Suitably secured to or connected with one of the sections D E of the handle C is a shaft or rod H. This in the form shown comprises a tubular rod which is secured at one end toa lug J, formed on or carried by section D of the handle. The opposite end of rod H is received in a socket formed in a shouldered plug or button K, the reduced head of which projects through au opening L in the section E when said sections D E are assembled. The shoulder on plug or button K is arranged Within the interior of the handle-section, and, engaging the inner periphery of such section, limits the extent of projection of the reduced head of the plug or button through the opening L, While permitting said plug or button to be moved or depressed into or toward the interior of the handle. The reelM is mounted or journaled to freely rotate upon rod H andl is provided at the opposite ends thereof with the flanges N O. One end of the skippingrope G is secured to this reel, the opposite end of such rope being similarly secured to the reel in the other handle. The end flange N is formed into achamber adapted to receive a thin ilat coiled spring P, one end of which is secured to the chamber or flange N of the reel and the other to the rod H. Thus the tension of this spring is constantly exerted to maintain the reel in one limit of its rotative movement, while permitting such reel to be rotated in the opposite direction. New the end of the skipping-rope G is secured to the reel when the latter is rotated to its fullest extent in a direction to wind up the springs, so that when released the spring willunwind and cause the skipping-rope to be Wound up or coiled upon the reel. A rim or projection of flange O of the reel is suitably provided with notches or ratchets (indicated at Q) adapted to be engaged by a detent or tooth R, formed on or secured to the inner periphery of section E of the handle.
' The detent or tooth Ris provided with a beveled edge, as shown at S, Fig 5, whereby the ratchet-teeth are permitted tot'reely pass or slide by said detent or tooth when the reel is revel-ved in a direction to cause the skippingrope to be unwound therefrom; but the reverse rotation of the reel under the influence of the operating-spring P is prevented. The reel M is mounted to slide or move longitudinally upon rod H, as Well as to rotate thereon, and a spring T serves to keep the reel pressed in the limit of' its longitudinal movement in a direction to maintain operative relation or engagement of the ratchets Q and tooth or detent R and also to keep the reduced head of plug or button K projected to its fullest extent through opening L. From this construction -it Will be readily seen that when it is desired to coil or Wind the skipping-rope upon the reel the plug or button K is depressed toward the interior of the han- `dle, thereby shifting the reel longitudinally and against the action of spring T and hence effecting a disengagement of the ratchet from the detent or tooth and permitting the spring P to effect the rotation of the reel in a direction to wind up the rope.
In practice I prefer to employ a chain for the skipping-rope by reason of the facility with which a chain may be coiled or Wound upon and unwound from the reel; but it is obvious that any other suitable or convenient cord or rope may be employed. It is also obvious that only one handle may be provided with a reel, the other end of the skipping-rope being merely fastened Within the other handle; but I prefer to employ a reel in each handle, as thereby the size of the handles may be minimized.
The operation of the device will be readily understood from the foregoing description. Taking the device in its assembled relation, as shown in Fig. l, if it is desired to use the skipping-rope the handles are pulled apart in the manner above described and the rope is uncoiled from the reels by the continued pull thereon, the inclined side S of the tooth R permitting the ratchets Q to ride thereover, but preventing reverse rotation of the reels. The uncoiling of the rope and the con-` sequent rotation of the reels causes the springs Plto coil up under a tension tending vto restore or reversely rotate the reels in a direction to coil the rope thereon. Vhen a sucient length of the rope is thus uncoiled, the article is ready foruse, and the rope will be held in the length to which it has been .uncoiled. If a greater length is required, further pull on the rope will continue the uncoiling thereof until the desired length is attained. If it is desired to shorten the rope, the button or plug K is depressed to effect a disengagement of the tooth R and ratchet Q, and thereupon the springs P will cause a reverse rotation of the reels and in a direction to coil the rope thereon, the plug or button being maintained depressed until the desired length of rope is attained. When it is desired to restore the apparatus to its compact and inclosed condition, the plugs or buttons are depressed until the rope is sufficiently coiled upon the reels, and then the tubes A and by inclosing the chain and forming a neat compact deviceconvenient for handling, packing, or shipping.
It is obvious that many variations and changes in the details of construction and arrangement would readily suggest themselves to persons skilled in the art and still fall within the spirit and scope of my invention.
While, therefore, I have shown and described are telescoped upon or into each other, there- IOO IIO
a construction which operatively embodies the principles of my invention, I do not desire to be limited or restricted thereto; but,
Having now set forth the object and nature of my invention and a construction embodying the principles thereof and having described such construction, its purpose, function, and mode of operation, what I claim as new and useful and of my own invention, and desire to secure by Letters Patent, is-
