Y zclaims. A(c1. 25e- 04) This invention relates to a novel device broadly entitled collapsible barricadeand has more specinc reference to a portable device expressly designed for street and highway use and intended i to be used as a safety` semaphore as well as/an indicator to show that the street is closed to traffic for some reason or equivalent purpose.r

Itis a matter of common-"knowledge that in certain danger zones and so-called quiet zones it is customary for the police and traic department to use portable signs, pedestals and the'like to notifytraflic that the street istemporarily closed because of repair work, or for some well deservingv reason requiring such vsafeguarding action. As a' general propositionV the device most frequently employedis a simple structure including an appropriate base, standard and a sign at the top' ofthe standard containing a proper notication for automobile drivers and the like.

The present invention relates to a device which is somewhat in the nature of a collapsible semaphore and which includes a foldable base, a standard and extensible semaphore or signalling arms having the requisite proportions and reach.

In reducing the invention to practice and selecting the preferred embodiment thereof, I have evolved and produced a structure which, in my estimation, satisfies the requirements of the trade and possesses such requisites of economy and simplicity as render it susceptible of unqualified endorsement for unlimited use, particularly for street repair work, or in thevicinity of schools as a safety device and so on.

Other features and advantages will become more readily Aapparent from the following description and drawings:

In the drawings:

Figure l is an elevational view showing the device set up for street use, said device being extensible to barricade more or less of the entrance of the intersection or street in which it is positioned.

Figure 2 is a top plan view of the arrangement depicted in Figure 1. n

Figure 3 is a sectional and elevational view diso closing the construction and arrangement and illustrating in particular the method of folding or collapsing into a compact assemblage.

Figure 4 is a fragmentary perspective of the upper end of the hollow post or column.

Figure 5 is an enlarged detail view taken approximately on the plane of the line 5-5 of Figure l.

Figures 6, 7 and 8 are sectional views taken on the planes of the lines 6 6, 1-1 and 8-8 respectively, of Figure l, the devicesconstituting the base being eliminated in Figure 8.

I call attention first to the standard'or column. This isin' the nature of a hollow, open-ended sheet metal tube and is indicated by the nu l5 meral S. At'the upper end I provide diagonally arranged keeper notches III to'serve a purpose to be hereinafter described.r At the extreme lowerA end or bottom I provide inwardly projecting stop Y lugs or ears I I. Adjacent thesek and in each wall of the lstandard I provide keeper notches I2. This particular type of la standard is adapted to accommodate or house the projectible and retractible devices or units serving as the supportingbase and barrier device. i f

The base comprises a special slidableY itting which is telescopically arranged within the tubular standard. This is in the form of av weighted metal slide andincludes a rectangular frame-like head or collar I3 formed with an integral depending extension I4 which constitutes a mounting or adapter means for the complemental leg or seat I5. There are four of these parts I5 and each one is in the form of an angle iron, the vertical flange being denoted by the numeral I6 and the horizontal ilange differentiated by the numeral Il. The flange I6 has an extension I8 which extends into the keeper slot, that is when the device is set up for use, and which extension is pivoted by a bolt and nut as indicated at I9 in Figure 7. With this arrangement, the slide` 20 is susceptible of being slipped up into the standard as shown in Figure 3 at which time the legs I5 are collapsed into a cluster-like parallelism. Thus the entire base comprising the slide 20 and the pivotally attached legs can be telescoped or retracted into the enclosing standard. When in use however, the slide or collar 20 drops down by gravity as the legs are pulled out by hand. The `pivoted extension I8 rests in the kerfs or keeper notches I2 and occupy horizontal positions extending at right angles to the bottom of the standard and this is suilicient to provide a well-balanced base which will prevent toppling of the barricade as a whole. `This extensible and retractible base construction is ingenious in a structure of this type.

Before introducing the extensible and retractible barrier portion of thestructure, I would state that this maybe made either relatively small as a simple doublearm head structure or the armsmay be made longitudinally extensible so that they may extend'or reach substantially across the mouth of the street in which the bar- Y ricade is placed. In other words the structure may be employed on a small scale more or less as an indicator or may be made sufliciently large to serve as an actual barricade. In principle however, the extensible and retractible barrier head comprises a metal follower 2| (see Figure 5) which is in the nature of a metal block and is sufficiently heavy to provide the requisite counter balancing features for the associated arms 22. The follower is actually provided with an upstanding central shank or attaching member 23 and it is to this that the inner ends of the arm are pivotally attached by a single bolt as indicated at 24. channel shaped cross section indicated at 25 are fastened by screws or the like 26' to the inner pivoted ends of the wooden arms 22. This provides for requisite longevity or durability. When not in use the arms fold with the follower into the standard as shown in Figure 3. When in use they extend at right angles out through the keeper notches I as illustrated in Figure 1. 'Ihe arms are actually composed of inner and outer sections 21 and 28, the inner section having a rib 29 and the outer one being formed with a groove to receive it. The rib and groove arrangement may be of the dove-tail form illustrated in Figure 6. A connecting bolt and nut 30 serves to join the sections together in extensible relationship. Thus we have a pair of arms of longitudinally extensible type having wear plates at their inner ends pivotally attached as at 24 to the stem portion 23 of the counterbalancing follower or mounting unit 2l. Obviously, then the arms can be adjusted as requirements dictate to employ the device as a simple caution sign or as an actual street barrier or barricade.

It is believed that the idea of a hollow standard having the extensible and retractible base Metal Wear plates or shields of and head units of the construction herein illustrated and described is ingenious and sufficient to serve the purposes for which the invention is intended.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details coming within the eld of invention claimed may be resorted to in actual practice, if desired.

Having thus described the invention, what is claimed as new is:

l. In a structure of the class described, a collapsible base, a standard rising from said base, barrier arms attached to the upper end of said standard, a hollow standard. a slide mounted in said standard, a plurality of legs pivotally attached at their inner ends to said slide, said legs being collapsible into the standard when not in use and extensible at right angles to said standard when in use to serve as a base for said standard.

2. In a structure of the class described, a hollow standard notched at its bottom and provided adjacent said notches with stop lugs, a collar slidable in said standard, a plurality of angle irons pivotally attached at their inner ends to said collar and cooperable with said notches and lugs in the manner and for the purposes described, and a slidable iixture in the upper portion of the standard, and barrier arms pivotally attached at their inner ends to said xture and oldable into the standard when not in use.
