TELEPHONE-BRACKET.

Specification of Letters Patent.

Patented Mar. 7, 1916.

Application filed December 30, 1914. Serial No. 879,739.

Indiana, have invented a new and useful Telephone-Bracket, of which the following is a specification.

Thepresent invention appertains to brackets, and aims to provide an improved bracket adapted particularly for holding or supporting adesk telephone set, whereby the same may be supported at different'vertical positions, and whereby the telephone set may be raised out of the way when not in use.

It is the object of this invention, to provide an adjustable bracket embodying a unique assemblage of component parts, whereby the bracket will permit the telephone set to be swung about a vertical axis,

as well as enabling the telephone set to be raised and lowered, and whereby the bracket will be simple, non-encumbering, rigid and inexpensive in construction, inexpensive to manufacture, composed chiefly of bars or strips or" metal, and convenient, practical and ei'iicient in its use.

Another object of the invention, is to provide a bracket embodying means for attaching it to a wall or upright support, or upon the top of a desk or other horizontalsupporting member.

It is also within the scope of the invention, to provide a telephone bracket which will be improved generally in its construction and details, to enhance the utility thereof.

'With the foregoing and other objects in view which will appear as the description 40 proceeds, the invention resides in the'combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the inl venticnherein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated 1n its pre I ferred embodiment in the accompanying drawin where1n:

Figure l is a side elevation of the bracket illustrating the arm thereof raised. Fig. 2 is a slightly reduced side elevation ofthe bracket with the arm lowered. Fig. 3 1s a top view of the bracket in a position illustrated in Fig. 2. Figs. 4 and 5 are enlarged sectional views taken on the lines 4-l and 55, respectively, of Fig. 1.

In carrying out the invention, the bracket comprises in its main essentials, a support- 1ng base member 1 attachable to the wall, desk or other support, a horizontally swinging member 2 carried by the member 1, a vertically swinging arm 3 carried by the member 2, and a clamp or holder 4 carried by the free end of the arm 3 for receiving and holding the standard of a telephone set or transmitter. The said parts will be taken up and described in detail in the order mentioned.

The supporting or base member 1 cmbodies an upright or vertical bar or strip 5 having its ends bent angularly as at 6, to

project forwardly. The bar 5 is apertured or otherwise provided with means for securing it to a wall or other upright support W as seen in Fig. '2. An upright bolt or spindle 7 is engaged through the angular ends 6 of the bar 5, and carries a lower nut 8.

A supplemental or auxiliary supporting or base member is employed in connection with the bar 5, for applying the bracket to the top of a desk or other horizontal supporting structure D, and to this end, an angular or L-shaped bar 9 has its vertical or upright arm attached to the back or" the arm 5, by means of bolts or other securing elements 10, and an inclined brace 11, formed from a bar, is secured between the arms of the bar 9 below the bar 5. The lower end of the brace or bar 11 is bent angularly, as at 12, to rest upon the end portion of the lower or horizontal arm of the bar 9, whereby a bolt or securing element 13 maybe engaged through the lowerend portions of the bars 9 and 11, while the upper end portion of the bar or brace 11 is bent, as at 14, to bear against the lower angular end 6 of the bar 5, and to be engaged by the bolt 7 so that the nut 8 being tightened, will clamp-the lower end of the bar5 and the upper end of the bar 11 together. Thus, the bar 11 will brace the structure, so that-when the lower horizontal arm of the bar 9 is secured upon the desk or other support, the upright arm or standard of the bar 9 will be held rigid.

The swinging member 2 comprises upper and lower doubled horizontal bars or straps 15, the bends of which are disposed rearwardly and form loops or hinge butts 1"3 embracing the hinge bolt 7 and bearing against the angular ends 6 of the bar 5, to hinge the member 2 to the member 1. A spacing tube or sleeve 17 is preferably dis: posed upon the bolt 7 between the loops 16, for holding the bars or straps separated and seated against the angular ends 6 of the bar 5. Anrupright bar or strip 18 is tel.- minally secured between the ends of the bars 15, by means of bolts 19, and an up- T ments 23 per bars 22, as at 25.

,of bars or strips.

- right bar 20 is secured between the limbs of the bars 15 by means of rivets or other securing elements 21, the bar 20 being disposed between the bar 18 and bolt 7, and the upper end of the bar 20 projecting above the upper bar or strip 15. ashers 21 are disposed upon the rivets 21 between the bar 20 and the limbs of the bars 15 to serve as spacers.

The vertically swinging or oscillatory arm 3 comprisesupper and lower pairs of bars 22, and upright links 23 terminally pivoted between the bars 22 of the upper and lower pairs, by means of rivets or other pivot ele Spacing washers 24 are disposed upon the rivets 23 between the links 23 and bars 22, the links 23 being preferably formed That link 23 nearest the member 2, projects upwardly above the up: The rear orinner ends of the upper and lower bars 22 are pivotally engaged to the upper and lower bolts 19, respectively, between the ends of the bars 15 and the bar 18, the bar 18 serving' as a spacer to separate the rear ends of the bars 22, as well as rendering the free portion of the member 2 rigid.

The arm 3 is spring pressed to normally assume an upwardly projecting or inclined position, as seen in Fig. 1, and to this end, a coiled wire eXtrac'tile spring 26 is disposed between the upper end of the bar 20 of the member 2, and the protruding end portion 25 of the respective link 23 of thearm 3,

- the ends of the spring 26 having the hooks 27 and 28 engaged respectively through an aperture 29 provided in the portion 25, and

a notch 30 provided in the upper end pore tion of the bar 20. The spring 26 being disposed between th'e'upper portions of the member 2 and arm 3, will be out of the way, and will also effectively serve its ofiice of raising the arm 3 and allowing the-same to yield or swing downwardly.

As a means for limiting the downward movement of the arm 3, when it is swung to a lowered'or horizontal position, as seen in Fig. 2, the lower ends of the upper bars 22 of the arm 3 are extended beyond the upper 1 pivot bolt 19, as at 31, and have recessed jor cutaway portions 32 which are engageable with a rivet or stop 33 engaged through the limbs of the upper bar 15 between the upthe bars 31 being disposed between the free ends of the respective bars 22, and an upright spacer bar or link 36 is terminally engaged to the rivets 35 between the bars 34. I An upright bar 37 is secured between-the bars 34: ofthe two pairs between the ends thereof, by means of clampingbolts 38,- and the free portions of the bars 3-1, beyond the bar 37 are curved or bent to provide complementing jaws 29 for receiving and clamping the standard 40 of the telephone set or transmitter. The upper end of the bar 37 is projected or extended above the upper bars 34:, as at 41, to engage under the upper or head portion of the standard 40, to support the said standard with the receiver hook spaced above the upper jaws 39, whereby the telephone set will not shift downwardlyi through the jaws 39 to such an extent, as to raise the receiver hookdue to the downward movement of thetransmitter standard.

In use, to apply the bracketto a desk,.the bars 9 and 11 are applied tojthe bar '5, whereby the lower arm of thebar 9 may be secured upon the desk orrother horizontal support D, as indicated in Fig. 1, whereas if the bracket is to be attached to a wall W as seen in Fig. 2, the-bars 9 and 11.are T:

removed. and the bar 5is secured to the wall. The member 2 being swingable hori-.

zontally and carrying the'arm 3, will' enable the arm 3'to be swung to one side or the other aroundthe vertical axis of the hinge bolt 7, so that the telephone set may he swung conveniently to and from the talking position. The arm' 3 being, nor mally raised under the influenceof the spring 26, will raise the telephone set out a of the way, and the telephone set may be readily lowered and moved forwardly totalking position, since the arm 3 is adapted to swing in a vertical plane. The links'23 hold the upper and lower bars 22 substan: tially parallel at their various positions. By removing the bolts 38, the transmitter standard 40 may be readily placed between the jaws 39, and by then applying and ti htening the bolts 38, the said standard will be clamped in place. and the member & willbe held in all positions of the arm 3, in such a position as to hold the telephone set upright.

, The salient tion resides'in the fact that the entire bracket is constructed chiefly of bars or I strips of metal, renderlng the structure simple in construction and manufacture, and

. p features of the present invenrendering it comparatively light and compact, the assemblage of the parts being such that the bracket is thoroughly substantial and efiicient in use. It is thought that the other advantages will be obvious from the foregoing, taken in connection with the drawing, without further comment being necessary.
