The invention relates generally to trailic' markrsroflthe type adapted to be embedded in the highway tobe irnarkeclthereby and lwhich proj'ect only slightly above gthe highwayV surface so as to niark but not obstruct traic, and it primarily seeks to provide 'a novel form of marker capable ofv being mounted withfacility and thereafter subiect to removal from and replacement to its mounting at the will of authorized attendants.

The practice generally followed in the placement of traffic markers of the character stated is to permanently embed the markers in the concrete Aor 'other material Aof which the highway is lformedand much'effort has been expended in attempting to design secure mo-untings of this nature.` However, when markers of thenow very popular and Widely Ademanded light reecting types are employed,` they must project a con- `siderable 'distance above the highway surface in order to properly house and position the reflectinglenses, and 'such markers are seriously dam- "ng'ecl lby the steel blades of snow plows during th/ewinter months. Y

Therefore; the invention has for an object the provision of a novel traino marker comprising a socket adapted to be permanently embedded in thev highway,fa 'marker unit readily mountable in and removable from the socket, and means for securing the marker in the socket against unauthorized removal.V Y

ALAnother object of the invention is to provide an improved trahie marker of the character stated `innvvhich means is Vincluded for releasably locking the marker in its socket `so' thatit can be removed Afrom the socket only by an authorized attendant entrusted with the proper key. Another object of the invention is to provide 'an :improved trahie marker of the character stated Ain which the removable marker and its receiving socket include parts which are interengageable 4in a peculiar1 manner for assuring proper registry oi the'locking or securing devices.

Another object of the invention is to provide an improved traffic marker of the character 4stated in which is included a spring set locking 'detent engageable in areceiving recess for automatically effecting a locked mountingupon insertion of themarker in its socket, and key-actuated means for effecting a removalof the detent from the recess lso as to permit removal of the 'marker yfrom its socket.

:Another object of the invention is to provide novel substitute marker elements removably mountable in the receiving sockets as temporary 'replacements for markers removed' for repair or to prevent obstructing free passage of snow plows.

Withthese and other objects in view which will moret'f'ully `appeanthe nature of the invention will be more Aclearly understood yby following the description, the appended claims, and the several views illustrated in the accompanying drawings.

Figure 15 :is a detail perspective view illustrating another rform of temporary `substitute marker member.

In the form ofthe-inventionillustrated in Figsures 1 through 8 of the drawings, there is included a socket body 5 which is non-'circular or generally rectangular in horizontal `cross section and includes a base flange 6 which-aids insecurely anchoring the-socket member in its Vintended position embedded inthe highway material 1 in the manner illustrated in Figure 2 `of the 'draw ings. l Y Y IThe socket body includes thesocket Shaving flared defining wall portions and which are adapted to removably receive the tapered shank 9 depending from the crown or dome shaped marker head I0. The marker head is of a diameter for extending a considerable distance beyond the mounting shank 9 in all directions, and its at under surface II is opposed to and adapted to snugly engage the upper surface of the highway 1 in which the marker structure is mounted.

The socket member includes a lateral socket extension I2 adapted to receive a lug I3 projecting laterally from the shank 9 and downwardly from the head I8, and the extension and lug provide complementary marker and socket member parts effective in a manner later to. be described for assuring a single den'ite relation between the marker and socket members. The crown head I8 of the marker member carries the usual reflector lenses I4, and it should be obvious that the particular shape of this head and the number and position of the lenses carried thereby can be variously changed to suit the conditions of use.

The wall of the socket member opposed to the lateral -socket extension I2 is provided with a locking recess I5 adapted to receive a locking detent I6 swingably mounted as at I1 in a recess I8 formed in the marker member shank 9. The detent is spring-pressed outwardly by a spring member I9 mounted in the shank recess I8, and

this detent automatically engages in the locking recess when the shank 9 is inserted into the socket 8 and thereby serves to lock the marker member' in its mounting socket against unauthorized removal.

In order to provide for the removal of theV sion 2D which may have a removable bottom wall 2I equipped with a slide groove 22, and a removable outer wall 23, said wall structures serving to enclose a lock chamber 24 within the housing extension. An unlocking bolt slide 25 is slidable in the grooveway 22 and carries a cylindrical bolt extension 26 projectible through a wall bore 21 into engagement with the -locking detent I6. Whenever the bolt is projected through said bore it will serve to displace the spring-pressed detent and permit withdrawal of the marker member shank 9 from the mounting socket 8.

Movement of the slide and

bolt unit

25, 28 necessary to effect the detent displacement just above described is effected by manipulation of a key 28 which is operable through a keyhole 29 formed in the housing extension 20 and a registering keyhole 30 formed inthe head I0. It will be obvious that when the proper key 28 is inserted and engaged with the slide 25 in a proper direction for forcing the bolt 26 against the detent I6, the desired displacement of said detent will be effected. Whenever the releasing key is not being used, entrance of foreign particles into the chamber 24 through the keyhole equipments f is Aprevented by the mounting of a removable plug 3|.

It will be obvious that should it be-found desirablefto remove the marker members 9, I8 for adjustment or repair purposes, or for preventing damaging Contact thereof by the steel blades of snow plows or the like, this removal can be readily eiected following releasing of the locking detent in the manner just above described.Y Under such conditions it will be found desirable to close the socket against accumulation of debris therein. rIhis may be accomplished by use of a simple, very flat, temporary replacement marker 32 having depending spring fingers 33 engageable in the socket 8 for removably securing the member 32 in place. The member 32 will serve not only as a suitable traiiic marker but will also electively close the mounting socket. The members 32 being very thin or at, and terminating peripherally in relatively sharp edge portions, can be used without interference with proper road clearance by snow plows.

` The marker members preferably are formed of white metal, and the socket members and the temporary marker replacements preferably are formed of brass so as to avoid the problems presented by accumulation of rust and corrosion.

In Figures 9 through 15 of the drawings, there is illustrated another form of traic marker embodying the invention. This form of marker includes a socket body 34 having a base ange or projection 35 for facilitating the permanent anchoring of the socket body in the concrete or other highway surfacing material 36. The body 34 is equipped with a cylindrical marker member mounting socket 31, andv at the upper end-of the body radially disposed socket extensions 38 merge into the socket 31 and extend upwardly through the body flange or enlargement 39. l

The socket 31 is designed to receive the shan extension 48 depending from the marker head which includes the flat flange enlargement 4I, a plurality of radially disposed ribs 42 being projected from the shank and the flange within the peripheral connes of the ange and adapted to have positioning engagement in the socket extensions 38. The crown portion 43 of the marker member` carries the reflector units 44, and, as previously stated, the nature and position of these units, and the shape of the marker head, canbevaried to suit various conditions of use.

A locking bore 45 is formed in the mounting shank 48 between two adjacent radial ribs 42 and inrposition for registering-with a slide bore communicating with a locking chamber '46 formed in a housing extension 41 carried by the socket member. The housing extension may include a removable bottom 48 having a slide groove 49 therein, and a removable outer wall 50.

A slide member 5I is slidable in the groove 49 and carries a lock bolt 52 which is projectible through the socket member bore into the registering bore 45 in the marker member shankv40. It will be yobvious that whenever the bolt 52 is thus engaged in the bore 45 the marker member will be securely locked in the permanently embedded socket member against unauthorized removal.

In order to permit removal of the marker member by an authorized attendant, the slide member 5I is provided with a key lug 53 which can beengaged by a suitable key 54, through a keyhole 55 provided in the housing 41 and a registering keyhole 58 formed in the marker member flange 4I, for the purpose of effecting a withdrawal of the locking bolt 52 and then the resultant releasing of the locked condition of the marker shank 40. Whenever the key 54 is not actually in use the keyholes are closed against ingress of the elements and foreign matter by a removable plug 51.

Whenever a key-actuated locking bolt has been withdrawn to release the locked condition of the marker member shank 48 and the marker member removed from its socket, the socket can'be closed against ingress of debris in the manner hereinbefore described by use of a temporary replacement marker 58 having depending'spring iingers 59 for removably retaining it in the socket 31.

It is of course to be understood that the details of structure and arrangement of parts may be variously changed and modified without departing from the spirit and scope of my invention.
