BARRICADE Emerson D. Sawyer, Chicago, Ill. Application August 2, 1940, Serial No. 349,961

5 Claims.

. The invention relates to improvements in barricades and has for its primary object the provision of an improved barricade arrangement adapted and arranged to guard roads at bridge heads, canals, high embankments, railway crossings and the like, against the passage of military tanks, troop lorries, trucks and the like, for defensive purposes in war time.

Another object of the invention is to provide a barricade of the character indicated which may be also employed for stopping ordinary peace time traffic to prevent accidents.

Other objects will appear hereinafter.

The invention consists of the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of the specification and in which Fig. 1 is a perspective view of a barricade embodying the invention;

Fig. 2 a similar view showing the barricade folded for the purpose of preventing the passage of heavy military Vehicles equipped with caterpillar tractors or the like;

Fig. 3 an enlarged vertical section taken substantially on lin 3-3 of Fig. 1;

Fig. 4 an enlarged section taken substantially on line 4-4 of Fig. 2; and

Fig. 5 a horizontal view taken substantially on line 55 of Fig. 2.

The embodiment of the invention illustrated in the drawings comprises two vertical rectangular columns mounted as indicated on opposite sides of a roadway and each consisting of a lower portion l and an upper portion ll hinged together at l2 to permit downward folding of the upper portion ll into the position indicated in Figs. 2 and 4. Splice plates l3 are permanently attached to the inner faces of the lower column portions l0 and are detachably attached to the upper column portions I l by means of bolts or the like so as to permit of the downward folding of the upper portions of the columns as will be readily understood.

A flexible payout barrier net 14 which may be of any usual or desired construction is arranged as indicated between the columns Hl and H, said barrier net being carried in the usual way by carriages arranged to reciprocate vertically in said columns and connected by cables l6 with counterweights I1. Operating chains l8 are also connected with the carriage l5 and the usual electric motors and whereby the carriages l5 and the payout barrier l4 may be elevated a shallow and narrow slot 2| and lowered in said columns as and when desired as will be readily understood by those skilled in this art. Vertical slots I9 are provided as shown in the inner faces of said columns so as to permit of these vertical reciprocations of the barrier M. The arrangement of the barrier and its operat-. ing parts is fully illustrated and described in my prior Patents No. 1,687,147, October 9, 1928; No. 1,699,545, January 22, 1929; No. 1,828,296, October 20, 1931, and No. 2,095,085, October 5, 1937, and needs no further description here. s I 7 While the barrier l4 may 'be' of any suitable or desired construction it is preferably made considerably higher than the usual barrier of this character, approximately six feet high, and its lower edge 20 is extended as indicated slightly below the normal top surface of the roadway, being provided in the lower roadway to receive said lower edge. By this arrangement the climbing of the barrier by caterpillar tractors is prevented and the passage of a prow or pointed implement under the barrier to raise it is also prevented.

Rigid portals or barricade frames 22 are extended as shown between the upper portions of said columns with suflicient space between them to permit of the elevation of the barrier net [4 to the tops of slots I9 and whereby the roadway may be readily cleared for the ready passage of ordinary traffic in peace time. The top cap of each column is provided with bolt holes 23 adapted and arranged to register with corresponding bolt holes 24 in the base plates 25 and 26 at the bottoms of the columns when the upper column portions I l' are swung downwardly as indicated in Figs. 2 and 4, and may be stoutly secured in such positions by stout bolts 21 so as to cause the portals 22 to constitute a stout and rigid barricade against the passage of military vehicles of any description. As will be noted the upper portion l l of each column is arranged to swing downwardly into abutting relation with the lower portion so that further swinging in this direction is positively prevented. Thus the barricade may be arranged across a roadway with the upper portions of the columns arranged to swing downwardly toward the possible approach of an enemy and whereby enemy advance from that direction may be positively interfered with or prevented, whereas advance in the opposite direction by home forces would be facilitated. The counterweight cables and operating chains, being flexible, will permit of this folding especially when given a little slack. Notches 28 are provided in the upper corners of the inner base plates 25 to tractors to facilitatethe climbing and passing of the same thereover.

By this arrangement a barricade is provided which may be advantageously utilized in peace time as a flexible payout barrier and which may be readily converted in war time into a stout and effective barricade to prevent or retard the passage of military vehicles. The specific form and arrangement is a simple and eiiectiveone for the purpose. I 7

While I have illustrated and described as the preferred form of construction for carrying the invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I therefore do not wish to be limited to the precise details disclosed but desire to avail myself of such variations and modifications as fall within the "scope of the appended claims.

I claim: p

l. A barricade comprising two columns arranged at opposite sides of a roadway; a portal extending between the upper portions of said columns, said columns being medially hinged to bring said portal close to said roadway to block passage thereover; a flexible payout barrier mounted on and in said columns to be elevated into a position adjacent said portal or lowered into cooperative relation with said roadway; and

'means for raising and lowering said barrier.

2. The barricade specified in claim 1 in which means are provided for strongly securing said portal in both elevated and blocking positions.

3. The barricade specified in claim 1 in which the lowering means is arranged to lower the barrier until its lower edge is below the normal surface of the roadway, there being a slot provided -in the roadway to receive the lower edge of said barrier.

4. A barricade comprising two columns arranged at opposite sides of a roadway; and a portal extending between the upper portions of said columns, said columns being medially hinged to bring said portal close to said roadway to block passage thereover, and to bring the upper portions of said columns into abutting relation with lower portions thereof.

5. The barricade specified in claim 4 in which a flexible payout barrier is mounted on and in said columns to be elevated into a position adjacent said portal or lowered into cooperative relation with said roadway; and means for raising and lowering said barrier are provided.
