To all wiiomit may concern: r

Be it known that we, EDWARD J. Bronson and EDWARD J. Sonnn'rrnn, citizens of the United States, residingat'Jackson, county of Jackson, State of Micni an, have invented a certain new and useful mprovement in Resilient Arms, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it ertains to make and use the same, reference eing had to the accompanying drawings, which form a part of this specification.

This invention relates to elastic arms for taking up the slack in the gas tubing or the electric current wire by "which, respectively, the gas or electrical energy is communicated, for purposes of heating, to a fiat iron.

It has forits object an improved means of keeping out of theway of'the operator whatever slack occurs in the tubing or wire as the iron is moved over the articl'ethatis being ironed, either toward or away from its conneetion terminal.

In the drawin s:-Figure 1, is a perspective view of the sec portion of the device, the u wardly extending arm bein broken off. l ig. 2, is a side elevation of t e entire device, the am, however, being somewhat abbreviated in length. Fig. 3, is an end elevation of the same portion of the device as is illustrated in'Fi l,

' A represents the base of the device through terminal ear portions A, of which holding screws may be passed. In itsupper surface is a circular racewa or supporting bearing for the balls B, whic separate from the base A the revoluble top 0, which is held to the base A in close engagement with the bearin balls by the bolt D. Shoulder portions rise from each side of the top piece C, and between them is journaled the hub portion F, from which rises the solid arm portion G.

The part F is supported upon pins H, which are screwed through the shoulder portions E, and somewhat into the body of the hub F, as shown in dotted lines in Fig. 3. From the top of the solid arm portion (3' rise a pair of armed and K, one of which, K, curves so that its free end is nearly at right an les in its extent with the main portion. t the outer end is carried a block L, through which may be passed the wire or gas tube, which it is desired to keep out of the way. The tension upon the tube may be regulated by the holding screws shown. The shorter arm J terminates preferably atab'ont the point that the arm K begins to WfVB,-Pt 1ds-lS*WOHDd quite tightly thereabout, though not necessarily fixed thereto. The-s ri Me a esclosel aboutthe hub rash fin th 03% 5nd N en gages against one of the shoulder portions so as to keep the spring in the pr'o er-degree of tension, while: the other on P engages a ainst the solid arm portion G, with a pull W ch tends to has it constantly, though yieldingly, in a near y vertical position.

The tension of the spring M may be re ulateclby a choice-between the various ho es 0 into which the end portion N may be inserted. A stop or nose Y at the base of the solid arm' portion engaging against the top portion C serves to limit the degree to whic the arm may rise under the actuation of the sprirn toward a vertical position.

As iong as it is not re uired to use the iron at the farthest end of t e article, or ironing board, from the point of its attachment to the line wire or gas pipe, the arm, maintaining, as it does, a nearly vertical osition, holds the tube, but little of whose ength is needed, well away from the Wire. When, however, the iron is moved by the operator to'the farther end of the. wire, the arm elastically ermits the increase of tubing to be drawn own toward the wire as needed, but as soon as the pull upon the cord or tube is slackened its resiliency operates to take up the slack. .The swiveling of the base portions A andC, by means of the ball bearing,

in combination with the-curvature of the arm, K and the resultant eccentricity of the block L through which the cord passes for attac- 'ment, results in the arm following in its inclination and direction the slightest lateral pull in either direction, so that there is at all'times the greatest possible yielding" capacity in the arm consistent with the efficient rotection of the work upon which the iron 18 being used. v

' What I claim is:

1. A resilient bracket, havin in combination with a base adapted to e fixed to a table, an upper piece swiveled thereto, ball bearings interposed between said face and 'upper piece, whereby saidupper piece is made easily rotatable with respect theretp,

an upright arm horizontally ournaled 1n' said upper piece, theupper end of said lower portion of said arm being provided with a 'nging away from the stop to prevent its SW1 normal upright position in one direction, and

length, and a spring engaging said top iece and the loiver end of said first mentionet arm. whereby said arm is yieldingly held in a sub stantially upright position with respect to the base, substantially as described. In testimony whereof, we sign this specification in the presence of two witnesses.
