ADJUSTABLY WEIGHTED DUMBBEILL Filed Feb. 16, 1951 INVENTOR. FLOYD w. LANDlS Patented Nov. 11, 1952 ADJUSTABLY w IcH'rED-DuMB EL 1 1 Floyd iiandis, Warsaw, Ind. Application February 16, 1951, Serial No 211,281

' This invention relates to" exercising devices, and more particularly to a special exercising weights on the arms above the hands in order that heavier I weights can be handled with shorter leverage for certain exercises in a series of' progressive weight handling exercises; whichjmay be of any desired length less than the arm length of 'theuser and may have a' length greater than the length of the forearms, so that the elbows will be held straight while the device isbeing used; which provides for adjustably moving the Weights toward and away from the hands of the user and for increasing or decreasing the weights to vary the exercises; whichincludes means for connecting a pair of the exercising devices to a single weight carrying bar; and which is simple,- strong and durable in construction, economical to manufacture, and easy to'use. I

Other objects and advantages will become apparent from a consideration of the following description and appended claims in conjunction with the accompanying drawing, wherein:

Figure l'is a top plan view of an exercising device illustrative of the invention, shown in op erative position on the arm of a user;

Figure 2 is a side elevational view of the 'device illustrated in Figure 1; Figure 3 is a cross-sectional view on the line F ur and Figure 4 is a perspective view showing an attachment for connecting the device to a weight carrying bar. 7

With continued reference to the drawing, the device comprises an arm receiving ring II] of a size to loosely receive the arm of the user either below or above the elbow, which ringis provided internally thereof with a padding II of resilient material, a handle I2 in the form of a cylindrical body spaced from the ring I and disposed substantially perpendicular to a diameter of the ring, and a pair of straight side bars I3 and [4 extending from the ring I0 to the handle I2, and each secured at one end to the ring and at its other end to the handle at the corresponding end of the latter.

The side bars I3 and I4 are secured, each at one end, to the ring In at the diametrically opposite locations on the ring, and are secured at their other ends to the handle I2 at respectively opposite ends of the handle, and the ring I0 4'Claims. (01.272-84) 1 hasits edges inspaced apart and substantially parallel planes which areperpendicular to the side bars I3 and'l l and substantially parallel to the handle I2. The longitudinal center lines of the handle and of the side bars lie substantially in a plane-which perpendicularly intersects the-planes including the edges of the ring and includes a diameter of the ring. I I

Wight supporting pins l5 and I6 are adjustably mounted on the side bars I3 and I4, respectively. Each of these pins is connected at one end 'to the corresponding side bar and projects substantially perpendicularly from the associated sidebar in a direction away from the "other side bar, and these pins are adjustably movable longitudinallyof the side bars to position the weights carried thereby at different distances from the hand of the person using the device.

In the arrangement illustrated, eachsidebar is provided with a medially disposed, longitudinallyextending slot, as-indicated at I1 and IS in Figure4, and each of the'pins -I5 and it comprises an elongated, cylindrical body having a bore extending coaxially therethrough. A bolt I9extends through the 'slot in the side bar I3 and 'through the bore in the pin 15 with its head bearing against the inner side of the side bar and a nut '20 is threaded onto the outer end of the bolt and bears against the outer end of the pin I5 to adjustably connect this pin totheside bar 1-3. --A similar bolt 2| extends through theslot' in the side bar I4 and through the harem the pin [6 with its head bearing against the inner side of the bar I4, and a nut r 22 threaded onto the outer end of the bolt bears against theflouterend of the pin I6 to adjustably secure this pinto the side bar I4; Centrally apertured, disc-shaped weights, as indicated at 23 and 24, such'as dumbbell-or bar bellweights, are mounted on the pins I5 and I6, respectively, and secured thereon by the collars 25 and 26 detachably mounted on the pins at the outer sides of the weights.

' The pinsare' long enough for each pin to receive several weights or to receive weights of different sizes, so that the amount of weight carried by the device can be varied as desired.

By positioning the weights between the hand and the shoulder of the user, the weights are handled with a shorter leverage from the shoulder than if they were held in the hand, and a greater amount of weight can be handled with the present device.

In the progressive series of weight handling exercises the weights may be shifted toward or 3 away from the hands of the user and. may be increased or decreased as may be desirable for the difierent exercises.

For certain exercises it is desirable to have a pair of the devices connected to a single weight carrying bar, such as the bar of a bar bell, and for this purpose an attachment is provided, as particularly illustrated in Figure 4.

The attachment comprises a strong, U-shaped bail or bracket having an intermediate or bight portion 3i and a pair of spaced apart and substantially parallel legs 32 and 33 extending in the same direction from the respectively opposite ends of the bight portion and substantially perpendicular to the latter. Apertured plates 34 and 35 are secured to the legs 32 and 33 at the inner sides and at the outer or distal ends of the. legs, and bolts or screws 36 extend through the apertures in these plates and through the slots I! and 18 in the side bars l3 and 14 to adjustably secure the bail to the side bars. It will be noted that the distance between the legs 32 and 33 of the bail is just sufiicient to receive the side bars and the attaching plates 34 and 35 between the legs.

A receptacle 3'! in the form of a T-fitting is secured to the outer side of the bight portion 3| of the bail 30 substantially at the mid-length location of the bight portion. In the arrangement illustrated, the cross portion of this T-fitting is secured, by suitable means such as welding, to the bail and the stem of the T-fitting projects outwardly from the bight portion of the bail. The cross portion of the socket or T-fi-tti-ng receives the bar 38 of an exercising device, such as a bell bar, which bar may carry weights, as indicated at 39, near its opposite ends. 7

As stated above, it is contemplated that a pair of the devices will be mounted in side-by-side relationship on the bar 38, but, as the two devices are substantially identical in construction, it has been considered necessary to illustrate one only of the devices attached to the bar of the bell bar.

The exercising devices may be held in position longitudinally of the bar 38 by threading a plug or set screw 40 through the internally screwthreaded stem portion of the socket or fitting 31 to bear at its innerend against the bar 38.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Thepresent embodiment is, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the-appended claims rather than by the foregoing description, and all changes which come withinthe meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.
