rIhis invention relates to barricade structure and more especially .to such structure for use in public places for guarding open eX- cavations and certain incompleted engineering work While other construction is continued to complete the operation intended.

My present invention has for its 'general object to provide a series of barricade units which are disassembled for storage or transportation, but which may readily be connected together to form a temporary but continuous guard to protect workmen from ntrusion by outside parties, as well as protect travellers from injury by advancing into the partially-completed work withoutsuitable warning.

A further object of my invention is the provision of units adapted to swivel connection one with another, so certain of these units may be mount-ed in alinement, though other units may be mounted angularly, permitting arrangement of such barricades in intersecting streets, and angular movement of the swivel units at varying angles, as may be desired.

A still further object of my invention is the provision of certain swivel units embodying therein not only means Jr'or supporting guard rails in intersecting relation, but also of joints for such support having rail-holders pivoted one upon another, so that the end of the rail in one holder will be readily swung to a different angle to the other.

`With these and other objects in view my invention consists in certain details of construction, which I will now describe and then specically point out in the appended claims, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a plurality of barricade sections connected together;

Figure 2 is a plan view of the structure shown in Fig. 3; f

Figure 3 is a side elevation of a barricade support;

Figure 4 is a similar view of a modified form of support;

Figure 5 is a plan View, and'Figure 6 a side elevation of a form of barricade support having one holder pivoted upon another;

Figure 7 is a transverse, vertical section of the form shown in Fig. 6, taken in the plane of the pivotal axis, and

. Figure 8 is an elevation of the swiveled holder without leg supports.

In the embodiment of my invention as illustrated in these drawings, the supporting legs for the connecting sections are designated by the numeral 5,-and guard rails or bars by the numeral 6. These bars are mounted in the several supports with their ends overlapping, being mountedin parallel relation when the part to be guard-ed is substantially straight, each sectionsupporting the ends of two bars.

` In Figs. 2, 3 and 4, is shown a supporting structure in detail, Jfor use in holding the ends of bars without permitting substantial move ment of one bar relative to the other. In Fig. 3, the leg 5 is integral with the rectangu lar holder 7 from which is bent downward the other leg of the pair. Between these legs a metal brace 8 closes the lower end of the holder, and the ends of the brace are riveted to the legs themselves. Upon the outside of the upper end of one of these legs, is secured a metal piece 9 formed at right angles to the base portion 10, thus forming an open holder 11 at the side of the main holder 7. This provides therefore for the insertion of a bar in the holder 7 and lowering the other har into the holder 11. The lower end ofthe base is bent in parallelism with the adjacent leg, so that the parts 5, 7 and 12 are secured by the same rivets 13.

In Fig. 4 I have shown the legs 14 integral with each other but not with the holder elements. The latter are formed of a separate piece of metal having one end 15 riveted to one of the legs, and bent upon itself to formv the closed holder 16, and again bent in parallel relation at 17 to form the open holder 18 as in the form described above. The base 19 of the holder 18 is riveted at 20 to the connecting portion 21 of the legs.

It is quite advantageous to provide for an extended barrier, one or more barricade supports comprising one holder pivoted 'upon another, so that the bar resting in the upper holder may be readily swung with its holder' 100 in a substantially horizontal plane, while the lower bar remains in a fixed position in the closed holder. I haveshown such a construction in Figs. 5, 6 and 7. I-Iere, the closed holder 22 formed by overlapping the ends of the metal and riveting together at 23, is riveted, or otherwise secured to the connection 24 between the leg members. rIhe open U- shaped holder 25 is pivoted at 26l upon the upper end of the lower holder.

The construction just described has an advantage in providing for swinging one or more units of barricade structure in a different direction from that in which the bar inserted in the lower holder extends. This is shown quite clearly; in Fig. 1, where this jointed construct-ion is designated as a whole by the numeral 30. As shown in Figs. 6 to 8 a-suitable'washer 27 is provided between the holders and may lbe replaced as needed.

It is not essential that the jointed holder 30 shall be used at the intersection of barricade sections extending at an angle to each other, only. It is vevidenttliat such form of support for overlapping bars may be used at one or more of the connecting points, or even at all of them. When however, the bars are to extendin one general direction for some distance it is quite serviceable to make use of the laterally arranged holders shown in Figs. 2, Band 4'; and for illustration of the adaptation of my structure to certain conditions, I have shown in Fig. 1 two of the fixed holders and three swiveled holders 30, but two of the latter shown in angular relation.

An advantage arises from the use of the thin and somewhat uniform character of bar metal in the manufacturev of all forms of this device. It is not expedient to form the legs or the holders 7, 11, 16 or 18, of heavy metal,

-as there is no excessive crushing strain to be opposed in normal use, and if some strong lateral pressure should be exerted against such connections, it is an advantage that the bar metal shall yield by bending rather than break, since the thin bar metal may be readily bent backto its normal form. It is well understood that this barricade structure is to serve only as a warning barrier adjacent engineering work such as building structure and excavations.

In all the forms shown, the parts are assembled by insert-ing one bar in the closed holder, and lowering the other bar into the open holder. This is true of both the fixed and pivoted holders. It is especially vuseful when the pivoted holder of Fig. Sis supported solely by the rail in the closed holder which, in this form, has no other support.

The bars are intended to lt the closed holders in all these forms, and thereby serve to avoid endwise movement of the barricades Theclosed holder 28 of the form in Fig.

8 is especially useful where the branch line of bars will be started from an intermediate part of the bar on which it is supported.` Such condition is shown clearly in Fig. 1. The several closed holders 7, 16, 22 and 28 will usually be of uniform size, though this need not be true of the bar ends intended to rest in the open holders.

Operation: In assembling the barricade,

A an operative stands in the track of the desired barrier, lifts an end of a bar with one hand and applies'a support thereto with the other hand, inserting the bar end into the closed holdervof the support. If a branch line is to be erected, `a holder 28 will be applied to the bar before another closed holder is applied to the end of the latter, after which the intermediate holder 28 can be moved to the exact positon desired. It then only remains to drop an end of the other bar into the open holder of the connecting support. The only` -detail the several elements of my barricade structure as it has been found serviceable to mount them, I do not desire to confine myself to the specific form or arrangements of parts shown since future use of the structure as described may suggest further changes or modifications that may fall within the scope of my invention as recited in the appended claims.' For example, it isto be noted that the use of thin bar metal for my simplified support structure, make practicable the feasibility of bending the legs of each pair of supports quite closely together forA the purpose of storage or shipment, and the same is to be taken as included in my inventive embodiment.

i Having described my invention, what I claim and desire to secure by Letters Patent, is: v
