CHARLES H. SAPPER, OF HIGHLANDS, NEW JERSEY, ASSIGNOR OF ONE-TENTH TO MELVIN A. RICE, OF NEW YORK, N. Y.

JUMPING-BOPE HANDLE.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed January 15, 1908. Serial No. 410,926.

To all whom it may concern:

Be it known that I, CHARLES H. SAPPER, a citizen of the United States, and a resident of Highlands, in the county of Monmouth and State of'New Jersey, have invented a new and Improved Jumping-Rope Handle,

of which the following is a full, clear, and

Figure 1 is a side elevation of a jumping.

rope provided with handles embodying my invention; Fig. 2 is a longitudinal section of one of said handles; Fig. 3 is a plan of a diaphragm provided with reeds and a pick for operating the reeds and Fig. 4 is an end elevation of the pick shown in Fig. 3.

As illustrated 1n the drawings, 1 represents a hollow handle which may be constructed of a metal tube, or in any other suitable manner, and provided preferably with a closed end 2 which may be constructed with a flange 3 adapted to engage the outer end of the tube. The opposite end'of the handle is provided with a head which, as shown in the drawings, comprises a flaring disk 4 having a central aperture and a flange 5 adapted to engage one end of the handle 1. A diaphragm 6 is arranged within said head and is held in place by the overturned edge 7 of a concave plate 8. The diaphragm 6 is provided with openings 9 and corresponding reeds 10 secured at their outer ends to the diaphragm by means of rivets 11, leaving the free ends of the reeds extending inward. A crank 12 is supported in the head of the handle and provided on its outer or free end with an eye 13 adapted to receive the knotted end 25 of a jumping rope 26. The crank 12 is off-set in a bearing 15 formed on or attached to the outer concave plate 8.

The inner end of the stem 14 isjournaled in a central aperture formed in the diaphragm 6.

The stem 14 is preferably constructed with an angular portion 16 and supports a picker 17 provided with a corresponding angular aperture adapted to hold the picker from rotating on said stem. The picker 17 is provided with a lifting edge 18 extending transversely of the axis of the picker, and also with inclined wings 19 arranged on opposite sides of the axis of the picker. This picker is also provided with a hub .20 adapted to be held against the face of the diaphragm 6 by means of a spring 21 mounted upon the stem 14 and secured in place by means of a washer 22 which engages the angular portion 16 of the stem. A washer 23 is mounted upon the stem on the opposite side of the diaphragm 6, and is held in place by means of a pin or by offsetting a bur 24 on the inner end of said stem or axle. In constructing the device the stem 14 of the handle crank is inserted through the central opening of the convex plate 8 and washer 22 placed therein. The spring 21 is then applied in place and then the picker 17. The diaphragm 6 is likewise placed upon said stem, and after being secured in place by means of the washer 23 and the pin or. bur hereinbefore referred to, the outer edge of the plate 8 is turned over onto the outer edge of the flaring disk 4, thereby clamping and holding the parts securely together.

When the device is in operation and the rope is swung in a circular. line, the crank 12 is rotated in its bearing and the picker 17 mounted on the stem ofsaid crank rotates therewith, and the front or lifting edge 18 of the picker passes under the inner or free ends of the reeds 10, raising said end up the inclined wing 19 which acts asa wedge under the reed, and after the upper portion of said wing passes the free end of the reed, the reed drops and produces a musical sound. The reeds may be of diflerent size to produce sounds of various kinds, or they may be of uniform construction. I By arranging the wings 19 on opposite sides of the picker and providing a common front or lifting edge, the picker is adapted to operate when turning either to the right or to the left so that the device operates the same when either of the handles'is held in the right or left hand of the user, or whether the rope is swung from front to rear or reversely. The wings 19 of the picker 17 incline away bodily from the lifting or entering wedge 18 of the pickers so that when the pickers are rotating in one direction one of the wings 19 will pass under the free end of the reeds, wing 19 by virtue of its inclined lower surface rides over the reeds with which it comes in contact. When the icker is reversed the wing that was before id e engages and raises the free ends of the reeds, while the opposite wing rides over the ends of the reeds with which it comes in contact. The interior of the hollow handle 1 communicates with the music box at the end of the handle, and serves to increase the sound produced by the rotating picker and reeds in the music box.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A tubular jumping rope handle having a hollow head connected with said handle, a dia hragm secured within said head, reeds radially arranged on said diaphragm, a rotary crank mounted in said head, and a picker mounted on the axle of said crank and adapted to engage the free ends of said reeds.

2. A tubular jumping rope handle having a hollow head communicating with the interior of said handle, a diaphragm secured within said head and provided with reeds radially arranged in a circular line, a crank mounted in said head, and a picker mounted on the axle of said crank and adapted to engage the free ends of said reeds.

3. A tubular jumping rope handle having a hollow head communicating with the interior of said handle, a diaphragm secured within said head and provided with reeds radially arranged in a circular line, a crank mounted on said head, and a picker secured to the axle of said crank and provided on opposite sides of its axis with wings inclined away from said diaphragm and adapted to engage the free ends of said reeds.

4. In a jumping rope handle, the combination of a hollow head, a diaphragm secured within said head and provided with a plurality of reeds radially arranged in a circular line, a crank rotatably mounted in said head,

a picker mounted on the axle of said crank and provided with oppositely disposed wings while the opposite .vided with oppositely inclined away from said diaphragm, and a spring mounted on said crank axle adapted to press said picker against the face of the diaphragm.

5. A tubular jumping rope handle having a hollow head communicating with the interior of the handle, a diaphragm secured within said head and provided with a plurality of reeds radially arranged in a circular line, a crank mounted in said head and provided with an eye on its outer or free end, and a picker mounted on the axle of said crank and provided with lifting wingsinclined away from the face of said diaphragm and adapted to engage the free ends of said reeds.

6. In a jumping rope, the combination with a handle, of a hollow head connectedwith said handle and comprising a flaring disk having a central aperture and a flange adapted to engage said handle, and an outer concave plate, having its edge engaging the outer edge of said disk, a diaphragm secured at its edge to the outer edges of said disk and plate, and provided with a plurality ofreeds radially arranged in a circular line, a crank mounted in said head, and a picker mounted on the axle of said crank and prodisposed inclined wings adaptedto engage the'free end of said reeds.

7. In a jumping rope handle, a hollow head, a diaphragm secured within said head and provided with a plurality of reeds radially arranged in a circular line, a crank mounted in said head, and a picker secured to the axle of said crank and provided with an entering or lifting edge and oppositely disposed wings extending'away from said entering edge and adapted to engage the free end of said reeds.

8. A tubular jumping rope handle having a hollow head 0 ening into the interior of said handle, ree s mounted within said hollow head, and means for operating said reeds.

In testimony whereof I have name to this specification in the two subscribing witnesses.
