ANTHONY J. LATELLA, on NEW YORK, N. Y.

CON ERTIBLE DUMB-BELL.

Specification of Letters Patent. I

Patented Oct. 13, 1914.

Application filed February 26, 1914. Serial No. 821,184.

To all whom it may concern: Be it known that I, ANTHONY J. LATELLA, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Convertible Dumb'Bell, of which the following is a full, clear, and exact de-1 scription. i i This invention relates to a dumb-bell of the convertible type, that is to say, it can be converted from an elastic or yielding dumbbell to one resembling a solidjdumb-bell, the weights of which are adjustable, whereby the article is of universal application.

The invention has for its general objects; to provide a comparatively simple and in expensive dumb-bell of the character referred to which is readily changeable from one type to the other as to weight.

Another obj vision of a dumb-bell which is split longitudinally and has a removable middle section to the ends ofwhich are applied adjustable weights, such middlesection being removable for permitting theside sections of the handle bars to be used in connection with one or more springs which convert the article from a solid to a yielding handle dumb-bell. I Y

A further object of the invention is the provision of simple, effective and novel means for uniting the parts of the dumb-bell adjustably and detachably together.

With such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views, Figure 1 is a plan view of the article shown as a solid bar dumb-bell; Fig. 2 is a perspective view showing the parts of the dumb-bell separated to illustrate the details of construction and with the weights removed; Fig. 3 is a sectional view of one end of the dumb-bell; and Fig. 4 is a perspective view showing the dumb-bell as of 5 the elastic or compressible bar type.

and easily adjustable; p 1 the middle section C areformed with spin ect of the invention isthe pro- Referring to the drawing, A and B designate the two main sections of the dumbbell, the middle part of the said sections being rounded to form a grip bar 1 and heads or balls 2 are formed on the ends of the portions 1. Disposed between the sections A and B is a middle sec sections, thepins having countersunk heads 4 in the section A, and thesection B has set screws 5 which are threaded in openings 6 in the end faces of the headextremities 2 of the section B, such set-screws having theirinner ends frictionally engaged with the connecting pins 3. The extremities of dles Twhich serve to receive a plurality of disks or other elements 8 of different sizes and weights, and these disks are held in collars 9 will be shifted inwardly so as to clamp the weights tightly against the main body of the dumb-bell and thus prevent looseness and rattling.

When the dumb-bell is to be converted bar, the middle section C is removed entirely from between the sections A and B, and helical compression springs 11 are interposed between the sections A and B, as clearly shown in Fig. 4c. The opposed faces of the sections A and B have seats or sockets v12 for receiving the ends of the springs, theouter springs being held in place by the connecting pins or fastenings 8. Obviously the number of springs can be varied according to the resistance desired, the maximum resistance being afforded by the seven springs shown in Fig. 4:. The intermediate springs can be removed if a lighter resistance is desired. The pins 3 pass loosely through the ends of the section A, so that when the two sections A and B are compressed together, the' section vA will slide on the pins or fastening elements 3. The pins 3 in this form or dumb-bell are longer than the pins required for the type shown in Fig. 1. a

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily under stood by those skilled" in the art to which the invention appertains, and while I have described the article which I now consider to be the best embodiment thereof, I de-. sire to have it understood that the article shown is merely illustrative, and that such changes may be made when desired as are within the scope of the appended claims. Having thus described my invention, I claim as new and desire to secure by Iietters Patent:

"1. A dumb-bell divided longitudinally into three sections, adjustable weights on the extremities of the middle section, and ,means for 'removably securing the outer sec- 25, tions to the middle section and permitting the outer sections to be detached while the weights remain on the inner section, said outer sections being located between the said weights.

'2. A dumb-bell divided longitudinally into three sections, adjustable weights on the extremities of the middle section, and: means for removably securing the outer sections to the middle section and permitting the outer sections to be detached while the weights remain on the inner section, said 'outer sections being located between the said weights and having seats .on their inner surface to receive springs whereby the dumb-bell is convertible from a solid handle to resilient handle device.

3. A dumb-bell having a grip portion and weight enlargements at its ends, and said dumb-bell being divisible in two parallel planes at opposite sides of the center to form a central and two outer sections, spindles extending axially from the ends of the middle sections, adjustable weights on the spindles, and means for removably fastening the outer sections to opposite sides of the middle section and permitting the outer sections to be removed while the weights remain on the spindles.

4. A dumb-bell having a grip portion and weight enlargements at its ends, and said dumb-bell being divisible in two parallel planes at opposite sides or the center to form a central and two outer sections, spindles extending axially from the ends of the middle section, adjustable weights on the spindles, and means for removably fastening the outer sections to opposite sides of the middle section and permitting the outer sections to be removed while the weights remain on the spindles, the inner surfaces of the outer sections being formed with seats for receiving springs whereby the dumb-bell can be converted into a solid or yielding grip device.'

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

ANTHONY J. LATELLA.
