These and other objects will hereinafter bemore fully explained, reference being hady tothe accompanying drawings forming a part of this specification, wherein like char- 0V acters will apply to like parts in the different Referring to the drawings, Fig. 1 is aperi spective view of one type of the signal.

My invention herein disclosed consists of a bed plate 1, having araised portion as at 1', the depression 'causedi thereby to receive a hinged portion when collapsed, said plate 1 being anchored to the roadbed of ahighway.
v Hingedly attachedto said bed plate is a secobj ecty of invention isto provide a signalriiexibly arrangedrso that an TRAFFIC SIGNAL ond plate 2, rocking on hinge 3. As a means of elevating the free end of plater 2, I have arrangeda leafspring 4, one end securely attached to the vbed plate in closey proximity tothe hinged end of the plate while the other endis in contactwith plate 2as'at A, by which means the said plate is tensioned upward, for the purpose hereinafter described.` In the free end of plate 2 isa slot 5 in whichA is positioned aframe, said frame being trunnioned to ears Z that are positioned on each sideof the slot. The lower end otsaid `trame is pivotally connected to a link 8, and
the opposite end of said link is pivotally connectedto kthe bed plate asat 8,:by which 65 means a toggle joint is arranged, and adapted to fold in either direction, as plate 2fis forced downward when thel indicia plate isy rocked to break the joint. Positioned on the upper ends of frame .is a bar 9 having a 70 channel-B to receive the loweredge of a flexible indicia plate. 10, said plate being secured therein' by rivets 11, by which `means it may ybe-replaced. The riieXible plate above reerred to has anindicia on either side thereofas shown in Figs. 1, 3 and 6, butI do not `wishto be confined to the exact wording, as
the mechanism may `be applied for other j purposes. Consequently the indicia would meet'the requirement whetherit be a signal, 80 or a signfor other purposes. l
vInxFigs. l6 and `7 is. showna modified form ofniy invention. In thisinstanoe Ihave employed a plate having a centrally disposed extended portionlO, the outer edge of which is seated in the groove offa member 12, said member pivotally connected to plate 2. Cen' tr'ally positioned andlaterally extending from tramer 12 is an arm 13, the outer end of which engageswith links 8, by which means the s toggle joint is arranged for this type of signal, being similar 'to the onefheretofore described.
In Fig. Gis shown a reinforcing means for the central portionof the plate, reinforcing e .Wires 14 extending through and into theV eX- .tended portion, vsaid Ywires being intermedi- C is free yto yiiexV should the Wheel of a vehicle 10o contact therewith, while the reinforced p0rtion has a greater resistance with respect to l an indiciai on eitherfside .thereof a'spring tentsionedplate, hingedly connected atl one end a pairofplates hingedlyconnected, and a its resilient qualities so that when a vehicle contacts with either side Vthereo,.tlf'ieptoggle joint willfbe promptlyrocled for thepurpose above described; and furthermore, should the joint haveV an obstruction.l against movement, the reinforced portion will flex sufficiently for the vehicleto pass thereover Without seri;k ous injury thereto. l/Vhenthe plate is -lthusl' formed and reinforcedl a qualtity jis attained.
