Application June 20, 1938, Serial No. 214,799- r l RenewedJune 6, 1940 v Thisinvention relates to barricades, particularly" adapted to street or roadrwork and it consists in the constructions, arrangements; and combinations herein described and claimed.

It is the cardinal purpose of the invention to provide a barricade which is collapsible for ready and easytransportation, and when erectedwill afiordfull safety to vehicular traflic and pedestrians.

It is also an object of'the invention to provide a barricade in which the supporting frame when in use, also functions asv ameans for, housing. the barricade when, in, collapsed condition.

It is a still further object of the inventionto provide a barricadein which the extremities of thebarricade areflexible, preventing, damage to alvehicle which. might encounter thatportion of 'the barricada. l

A. further object of the invention is to provide a barricade of a flexible, character which may be shaped. to circular formation for protection, of man-holes and the like.

Additional objects, advantages and features of inventionwill be apparent from the following description and accompanying drawing, wherein Figure 1 is a plan view of the barricade in ,collapsed shipping position.

Figure 2 is a perspective view of the barricade in use.- i

Figure ,3. is a plan, view of the barricade when erected for protection, of, a,man-hole or the like.

Figure, 4 is, across section on the. line, 4-4. of Fig. 2. a

Figure 8 is a. fragmentary detail illustrating thejmounting of a signal jewel.

Figure 9 is an enlarged cross section through a pair of the lazy tong links. I

Attention is first invited to Figure 1 of the drawing whereintthe barricade I is shown in collapsed position-and confined within a frame structure I I, which, in the presentinstance, comprises five hingedly connected sections I2, 13, I4,

l and 16, which in their collapsed position form a housing for the barricade, as will appear as the description proceeds.

The sections l2--l6 are U-shaped channel bars of light construction, hinged together as indicated at l1, I8, I 9 and 2|]. The top channel bar 14 and the lower bars l2 and I6 are of substantially equal lengths, but the bars [2 and I5 are (Cl. 256.1) individual bars and jointly aggregate the length of the bar I4, their abutting end edges meeting medially of the length of the bar I4.. Thus, it will be seen that thebars I2 and lfilie parallelto the bar l4 constituting the longitudinal sides-of the frame and that the sections l3 and I5'which are of lesser length the housing. v i t l 1 The barricade lflin the present instance' is shown as of an extensiblestructure, of the well known lazy"tong'p'rinciple comprising pivotally connected links 2|,and since'this structure 'is well understood, a detailed description'is hot thought necessary for :a full understanding of the invention. However, it should be understood that the links 2l are extensible in a lengthwise direction to effect a barricade, and 'since t he links are constructed of a flexible steel, su-ffi'cient flex ibility is inherent to permit the flexing of the links into a circular formation for encircling a man-hole or the like, as shown in Figure 3.

The channel bar Mihas an aperture formed intermediate itslength adapted 'to' align with an .ap'erture of the upper pivotallyconnected ends of a pair of lazy tong'links, a'ndfbetween the registered apertures a cotter pin 22 is inserted, insuring retention of the barricade Ill within the constitute'the end portions of channel bar. Thee-nd channel bars I2 and I G spacer washer 23 for separation" of the links '21,

each link 2i beingapertured to receive an eyelet rivet 24, respective ends thereof being upset to secure the links.

With further consideration to Figure l, in order to erect the barricade to the position shown in Figure 2 the cotter pins 22' are removed from their respective eyelets, as isthe cotter pin 22, which will allow the sections" t2, I3, l4, l5 and Hi. to be swung upon their pivots l'l, l8, I9 and 26,

into, longitudinal alignment, as shown in Figure l 2. The barricade H1 is nextmoved to "its 'extended position, which may be accomplished by grasping the knobs 25 and exerting an outward simultaneous movement to the links, until a desired extension of the barricade has been attained. The aligned sections l2, l3, l4, l5 and I5 are now presented over the upper end portions of the links 2|, so as to register eyelets of the links with apertures of the sections l2, M, and It, when a cotter pin is, again inserted through aligned apertures and eyelets. Thus, the barricade will be maintained in extended position.

In order to support the barricade, four detachable legs 26 are provided, constructed for a 5 slip-on connection with lower extremities of cerposition of the barricade obviously presents the linksv 2| at an angle and therefore thesocket 21 will be fixed to the legs 26at such angle as to preferably the mutually hinged links will be engaged by respective legs and sockets in "order to provide a stable structure.

The base portions of the legs 28 may have any desired formation for support of the barricade, and in Figure 2 the leg 26 terminates in a pointed portion 29- adaptedjto penetrate a road surface, while Figures'5' and ,,6, the leg terminates in diverging members 30 and'3l. The member 30 is constructedforpenetration of a surface, while the member 3l isadapted to rest upon a surface and isprovided with an'aperture32 for reception of an anchorage bolt or fastening 33. 1

1 Fromth'e foregoing, it will be readily seen that the legs maybe readily det ached or attached to linksof; the barricade, and preferably, the legs are arranged in opposed pairs, as clearly shown in Figure; 2, and inpractice, it has been found desirable to place the legs Well inwardly of the extremities of the barricade, forthe reason that by-such placement of the legs flexible end portions of {:the barricade are provided, as indicated at 3,4} and, 35, permitting forcible contact with the ends by a vehicle, without damage to either in the barricade or the vehicle, since the ends of the barricade wil readily flex, permitting passage of the vehicle until b rought to a stop. 7

* It isoften necessary to place a barricade or guard around a man-hole or the like, and the 45 present structure is susceptible to such use, as

illustrated in Figure 3, and in such use, the channel members |2-Hi are not used. The barricade in this instance is flexed to a circular shape, the extremities of the links 2| being over- 59 lapped to register apertures of the links for engagement of cotter pins 25d. The supporting legs 26;will be engaged with links of the barricade,

. as previously described, but they will be equally and 'circumferentially spaced around the periphery of the barricade.

Reflecting prisms have become generally used as traffic-signal devices and it will be apparent that such prisms maybe readily incorporated with the present barricade. Such prisms maybe incorporatedupon the barricade in various man ers, butin Figure 8 we haveillustrated a bolt 34 of a .size to be received through any of the eyelets 24,'bearing a reflecting prism 35. These prisms may be arranged upon the barricade in anydesired manner, for instance, the prisms may be arranged in staggered relation, red and green readily accommodate the links to be engaged and alternating, or one end of the barricade may comprise all green signals and the other end red signals.

The legs 26 when detached may be secured to the barricade, when in collapsed position, by means of brackets 36 secured by bolts in suitable eyelets of the barricade.

When it is desired to collapse the barricade, the cotter pins 22--22' are removed, permitting removal of the channel sections -|2l6, when the barricade may be collapsed by grasping the knobs 25 and moving them toward each other.

When the barricade has been fully collapsed, the

barricade is placed within the channel sections |2'-'lfi.

The sections are then moved so as to encompass the barricade when the cotter pins 22-22 are'replaced to effectively house the barmembers inwardly of the extremity of the eX- tended position of the link members whereby to provide freely flexible end portions.

2'. A barricade comprising a hingedly connected U-shaped frame member, certain of said sections having transversely extendedap'ertures, a series of pivotally connected link members arranged for simultaneous extension and retraction, said link members having apertures for registry with apertures of the sections, a pin member engageable through registered apertures of the frame member and links, and detachable support means engageable with certain of the link members.

'3. The structure of claim 2 in whichthe supportmeans include a socket at one end for reception of a link member, the opposite end having surface penetration and ground anchorage means.

4. The structure of claim 2 in which the link members include light reflecting prisms. '5. A barricade for highways and the'like comprising a series of'link members, for simultaneous extension and retraction, a hinged U-shaped frame member engageable with the upper ends of the link members, means for securing the frame to certain of said link'members, detachable support means engageable with certain link members, said support means having a' socket for reception of the link, and said support means being positioned upon opposite sides of links of the barricade and including a' penetration point and an anchorage foot.
