LIFE NET Filed Dec. 28, 1945 Patented Feb. 11, 1947 UNITED STATES PATENT OFFICE LIFE NET George Bauerlein, Sn, Talladega, Ala. Application December 28, 1945, Serial No. 637,584

Claims. 1

This invention relates to life saving, and more particularly'to escape apparatus in the form of a net and a method of supporting the same so that a person or an object descending through the air with substantial velocity may be caught in the net and the shock of landing cushioned sufiiciently to prevent serious injury or damage thereto.

Fire fighting nets have been used for catching persons and objects by firemen or other individuals. Heretofore this has required the attention of several persons as it was necessary to hold the net in a particular manner and still there has not been any definite assurance that the net would be properly held.

It is an object of the invention to provide a net and supporting means therefor, which need not be attended when in operative position, which may be easily set up by one or more persons and left unattended and will serve to safely receive persons or objects descending through the air from a substantial height without damage or injury. The invention actually is a life net.

Further objects and advantages of the invention will be apparent from the following description taken in conjunction with the drawing, wherein:

Fig. 1 is a fragmentary perspective illustrating one application of the invention, and

Fig. 2 is a side view illustrating one of the supporting standards and associating parts.

Referring to the drawing, fire trucks Ill and I I are provided with rear steps or platforms I2 and I3. Standards M are mounted on the steps, one adjacent each end of each step, and each standard is provided with a base l5 having a relatively broad flange l6 and an upstanding sleeve I1 disposed at right angles to the flange.

The flange I1 is adapted to be secured by bolts or other fastening elements Hi to the floor or step l2 and form an anchor or support by means of which the device is secured on the step of the vehicle. The steps or platforms I2 and I3 have apertures corresponding to the bores of the sleeve I! so that the standards M may project slightly below the steps or, if desired, may project below the steps sufilciently to engage the surface on which the trucks are supported.

In order to provide vertical adjustment of the standards I 4, these standards are provided with openings I 9 for the reception of a pin 20 anchored to the base l5 by means of a chain 2|.

Each standard l4 may be braced to the truck by means of a bracket 22 each having one end 2 fastened to the truck and its other end fastened to the standard l4. Either end of the brace may be detachably constructed for the necessary adjustment.

The standards 14 are provided with receiving arms 23 having on their free extremities outwardly bent portion 24 for guiding net pole 25 into the space between the arm or bracket 23 and to the standard I4.

Each net pole 25 is attached to the end of a net 21 and said pole is adapted to be supported by a pair of standards above each step or platform and substantially parallel thereto.

The inner portions of arms 23 are substantially parallel to the standards M and the net poles 25 are provided with square portions so that when they are received between the arms and the standards they will not rotate. In this way by rolling the net pole, the tension of the net may be varied.

In applying the invention to fire trucks the base of each standard is secured to the steps or platform at the rear of the truck and a standard is applied to each base. The trucks are maneuvered until their rear ends are spaced the desired distance, and the net poles are placed on the rear sides of the standard between the arms 23 and the standards l4, one or both of the net poles may be rotated until the net is at the desired tension. This tension may also be ac complished by placing the net poles in operative position and driving one or both of the vehicles away from the other until the net is at the desired tension. When thus installed the net will serve to cushion the descending persons or objects. Attendants are not, therefore, required for holding the net but are free to do fire fighting while people are being saved from a burning building.

It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is shown in the drawing and described in the specification but only as indicated in the appended claims.

What is claimed is:

1. Fire fighting apparatus comprising in combination standards constructed to be supported on the rear steps of fire apparatus, one standard at each end of each step, a safety net constructed to be supported by said standards, a supporting base for said standards including sleeve means for vertically adjustably supporting said standards, an arm on the rear of each standard having a portion spaced from said standard, a net pole attached to each end of said net, at least'one of said poles having a non-circular portion to fit between one of said arms and its supporting standard and be held against rotation whereby such net pole may be removed from its operative position and rotated and the net wound around the pole for varying the length of the net.

2. A safety net for use with fire fighting apparatus, a net pole secured to each end of said net, a pair of standards for disposition in spaced relation for supporting each net pole, an arm on each standard for holding the net pole against the standard, means for supporting said pair of standards in spaced relation on spaced vehicles in a manner to stretch said net, and means whereby said net pole is held against rotation.

3. A safety net for use with fire fighting apparatus, a net pole secured to each end of said net, a pair of standards for disposition in spaced relation for supporting each net pole, an arm on each standard for holding the net pole against the standard, and means for supporting said pair of standards in spaced relation on spaced vehicles in a manner to stretch said net.

4-. In combination with fire fighting apparatus a safety net, a supporting pole for each end of said net, means for supporting said net in operative position comprising a pair of spaced supports for each of said poles, each pair of supports being constructed to be carried by a separate vehicle and the vehicles being operable for varying the tension on the-net.

5. Fire fighting apparatus comprising in combination spaced standards constructed to be supported on the rear portion of fire apparatus, a safety net constructed to be supported by said standards, a'supporting base for said standards including means for vertically adjustably supporting said standards, a support on the rear of one of said standard having a portion spaced from said standards, a. net pole attached to the end of said net, and having a non-circular portion to fit between said support and said standard and be held against rotation whereby such net pole may be removed from its operative position and rotated and the net wound around the pole for varying the length of the net.
