fRoDERIcK A. PEGK AND ALEXANDER W. MecLEAN, or sT. LOUIS, MISSOURI.
, UNIVERSAL, Ex'rENsIBLR,` RALANcED BRACKET.y
and ALEXANDER W. MCCLEAN, citizens of the United States, and residents, respectively, of St. Louis, Missouri, have invented certain new and useful Improvements in Universal, Extensible, Balanced Brackets, of which the lfollowing is a specication containing a full, clear, land 4exact description, references being had to the accompanying drawings, forming a part hereof.
Our invention relates' to improvements in vuniversally extensible and balanced brackets, arranged for the support of various devicesrsuch as telephones and toilet mirrors, wherein parallelbars, mounted to be swung in one plane of movement are carried on a .base arranged to be swung in another plane of movement, and which bars carry at their outer free ends a number of hinged leaves to which the device to be supportedv is connected to be swung to an innitenumber of positionsV both radially and circumferentially of their points offconnectio'n with the parallel bars, and wherein means are provided forv balancingthe bars to automatically maintain the supported device in various selected positions and other means provided for locking the bars in various selected positions.
Our Objectis to 'construct a.v simple, durable and inexpensive bracket, for instruments, which require, for their best eiiciency, a relatively stable yet shiftable support. n
Our improvements consist in the novel details of construction, arrangement and com` bination of parts, hereinafter fully, clearly and concisely pointed out in our specification, pointed out in our claims-,and Villustrated by the accompanying drawings, in which,-
Figure l is an elevation of the bracket as fixed to a support, and in a position when not in use, and shows by dotted lines, the bracket fully extended for use.
F ig, 2 is a plan of the bracket, fully ex@ Fig. 5 is a detail elevation, partly in section of a Vmodified form of means for the support of an instrument.
Specification of Letters Patent.
Patented July 16, 1918.
Application filed March 23, 1917. Serial No. 156,904.
Fig. 6 is a transverse sectional elevation of the pairs of parallel bars and the clamp for locking them in different set positions, and
Fig.- 7 is a fragmental elevation of one of the clamping members.
Referring by numerals to the drawings, 8 designates a base having at its upper and lower ends the journals 9, arranged for support in bearings 10, adapted for securement to a fixed support, such as a wall, desk, table or vthe like.
Extending laterally from the base and spaced relatively are the perforated ears 11 arranged to receive pivots 12 on each of which pivots there is swung a pair of parallel bars 13. The pairs of bars 13 extend to and are each pivotally connected with an element comprising a pair of disk-shaped bodies 14 and a hinge leaf 15, with their points of connection with said element relatively spaced a distance corresponding with the spacing of the pivots 12.
By preference, we extend a bolt 16 throughr the lowermost pair of arms 13 and provide a Wing-nut 17, whereby to lock the clamp members 14 against relative rotation at times to positively hold the parallel bars in different set positions, and as shown in Fig. 6, the meeting faces ofthe clamp members are dished so that there may be free relative rotational movements, at times.
For temporarily holding .the clamping members against relative rotation, we pro vide a plurality of seats 18, in concentric arrangement, in the meeting face of the one clamp member and a hollow boss 19 in the other, in which boss we insert an extensile coil spring 20 and a ball 21, arranged to be yieldingly held in one or the other seats 18.
As a further means for holding the arms 13 in different set position, we provide a contractile coil spring 22 which is extended diagonally of the trend of the parallel bars and has its one end secured to the one pair of bars adjacent the uppermost ear 11, of the ybase 8 and its other end secured to the other pair `of bars adjacent their lowermost point ofpivotal connection with the clamp members 14.
The spring 20 is given tension in proportion to the weight of the device to be supported,'and therefore balances the device in different positions.
Connected with the hinge leaf 15 is a second hinge leaf 23 of greater length than the leaf 15, and secured to the leaf 23 is a third end of said base,
leaf 24', of approiiimately one-half-the'leiigt-h of the leaf 23, vvhereby When the leaves are Jfolded to substantialparallelism the fre'eend of the outermost leaf 24 lies adjacent the vertical median line oft'he'clampmembers,'
so that the springv 22 may operate to balance 'andhold in -various set positions Ithe 1 Weight of the device supported..l n y y The Jfree end of the outermost leaf 2% is provided with a vertical bore arranged Vto receive the stem 25 of a'device to be supported.
Inllig. 5 We vshow the, stem 25 yas'being a part of the supported device, While in Figs. 3 yand live show the stem 25 as being av part l of aclamp 26,*Wl1ereby the supported Vdevice may be held in various vertically vadjusted positions Vprelati-ve .to the hinge'leaves. y
Projecting laterally fronitlie clamp 14 is "f a fork 27, arranged for the'supportv of a de- 1 vice functionately associated' With-.the sup-y portedrlevice.previously referred to; 'that is, the fork 27Vmay be employed asa support for a shaving brush when the bracket 1s supporting a'mn'ror, as shown in det-ail vto the .uppermost pair of bars and itsropp'obars, 'clamping members carried by the lowerino'st pair ,offbars for holding --the'bars in diierentset positions, a pivotal connection bet-Wieren one' ofthe cl-aiiping members and the uppermost pair of bars, a series of folding sectionsicarrled by one oi said clamping v members, anda pivotal support for the article to be supported carried by the outermost one of the foldingsections.
