L. B. SOMERBY.
Patented Sept. 29, 1891.
UNITED STATES PATENT OEEICE.
LORENZO B. SOMERBY, OF NEVARK, NEV JERSEY.
SPECIFICATION forming part of Letters Patent No. 460,270, dated September 29, 1891.
Application led June 11,1891. Serial No. 395,894. (No model.)
To all whom it may concern.-
Be it known that I, LORENZO B. SOMEEBY, acitizen of the United States, residing at Newark, Essex county, New Jersey, have invented certain new and useful Improvements in Gyrating Dumb-Bells, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.
This invention may be termed a gyrating or eccentric dum b-bell; and its object is to furnish a construction in which the weights may be rotated around the handle by a swinging or jerking motion of the hand. To effect this object, the handle is cranked at both ends and the Weights attached to the ends of the cranks.
The annexed drawings show a side View of the dumb-bell in Figure l provided with a sleeve upon the handle, while Eig. 2 shows a similar View with naked handle; and Eig. 3 shows an end View of the same.
a is the handle, h the cranks at the ends of the same, and c the Weights affixed to the bent ends of the cranks.
d is the sleeve, formed,preferably, of wood and held in place upon the handle between xed collars c. Such a handle may be made of a wrought-iron or brass rod bent to the desired form after the sleeve is applied and having the balls c secured upon the bent ends of the cranks.
Fig. 2 shows a construction adapted to be formed entirely of cast-iron, with the handle, the cranks, and the balls all in one piece. The handle is grasped by the hand of the operator and gyrated in such a manner as to rotate the Weights around the handle, the swinging of the weights bringing into play a great many muscles which are not at all exercised by the ordinary solid dumb-bell.
Vith the form shown in Eig. l the handle would rotate Within thesleeve; but with the construction shown in Fig. 2 the weights would be rotated about the handle by permitting the latter to slip around in the hand, and the rotation of the weights may be arrested by gripping the handle at any time.
The dumb-bell may be held in anyposition and gyrated by a suit-able movement of the hand and arm, and the balls c may be made of any suitable material and Weight to secure the desired exercise.
As the rotation of the weights exercises a great many muscles which are not called in play by the lifting or twisting of the solid dumb-bell, it is obvious that a lighter weight is required for my gyrating bell to secure the same exercise than is required with the ordinary solid bell. The gyrating bell is therefore especially adapted for classes in calisthenics and physical culture, Where grace and freedom of motion are cultivated. My gyrating dumb-bell also furnishes an agreeable change after exercising with the ordinary dumb-bell to iirst excite the circulation.
Having thus set forth the nature of my invention, what I claim herein isl. A dumb-bell having the weights affixed eccentrically to the handle, substantially as set forth.
2. A dumb-bell having the weights aiiixed eccentrically to the handle, and a sleeve applied to the handle, as and for the purpose set forth.
