7 Claims. 1
This invention relates to escape means from a burning building by providing means for supporting a housed net at each corner of the building with means forextending said nets across each side of the building in case of a fire, said not "being preferably disposed immediately below the windows of the secondstory so that regardless of the height of the building, persons may jump from the windows and land on the net fromwhich point they can drop to the ground or berescued by fire departments and the'like.
It is an object of this invention to provide girders extending from each corner of the building, and each side of the building having a housing in which a net is stored, said net being adapted to travel along cables orrods running from one end of the building to the other when a fire occurs in the building, said nets being extensible by motor driven means, which motors can be energized from the clerlis desk or any other suitable location within the building.
It is another object of this invention to provide the escape means comprising means associated with each corner of the building for supporting a net extending from one corner of the building to the other and with a housing in which the net can be housed against the weather and with motor driven means connected to the free end of the not so that it can be extended from one corner of the building to the other below the lower windows or immediately above the ground floor so that persons entrapped in the upper stories can jump into the net from whence they can be rescued.
Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which Figure 1 is an elevation of one side of a building showing my invention attached thereto;
Figure 2 is a sectional plan view taken along the line 2-2 in Figure 1 and showing portions of the building and mechanism broken away;
Figure 3 isa vertical sectional view taken along the line 3-4 in Figure 2;
Figure 4 is a vertical sectional view taken along the line t-4 in Figure 3;
Figure 5 is a vertical section-al'view taken along the line 5--5 in Figure 3;
Figure 6 is a sectional plan View taken along the line 65 in Figure 3 and omitting certain parts;
Figure 7 is an elevation taken along the line '!"I in Figure 2, and showing the ou'ter Wall of the housing for the net broken away; and showing the movable door in closed position;
Figure 8 is a vertical sectional view taken along the line li--8in Figure 7.
Referring more specifically to the drawings, the numeral l0 indicates a building of any desired height having a plurality of stories therein and each story, of course, having a plurality of rooms with windows I! therein. The ground line-on which the building is situated is indicated at l2. In order to provide means of escape throughthe windows of the various stories of thebuildin'g; 'I have devised means for extending a 'net b'elow-all of the stories except the ground floor into which the occupants of the room's may jump in case they are entrapped by fire in the building. As
the equipment on the four sides of the'b-uilding is identical, a description of the mechanism associated with one side of the building willjbe given, and like-reference characters'will apply'to the other sides of the building. The building walls have usually a steel frainework comprising vertically disposed I beams through-out the wall structure and especially at each corner of the building. r
The vertically disposed I-beams are indicated at 9 and each of these I-beaIns has welded thereto and extending outwardly therefrom a horizontally disposed I-beam 8, and the outer end of each I-beam B has an eye I? therein to which is connected a guy link l5 whose other end is connected to an eye member 1 which is wel-ded'to the vertically disposed I-beam frame member 9'. Also secured to each vertical I beam '9 is an outwardly extending I 'beam i6 which has an eye H in its free end to which is connected a guy link l8 vg hose other end is connected to an eye l9 which in turn is welded to itsasso'oiated I -beam 9. The l-beam 8 supports a housing 213 and said housing is-also secured to the wall of the building by' lag screws 24. This housing 2!] has a top, bottom, two side members, a rear end member and'a movable-door 22; Penetrating the I-beams 8 and f6 are spaced guy rods or guy cables 23 and 24 which completely encircle the building.
Disposed on the side of the I- beam 8 which faces the I-beam I6 is a pair of eye bolts 26 and 21 through which a cable ZB'is passed, the cable being doubledupon itself where it passes through the eye bolts 26 and 21 and has suitable securing means, such as a wire 31!, attached therearound to prevent slippage of the cable 28 relative to the eye bolts 26 and N. This cable also passes through suitable eye bolts 35 and 35 secured to the proximate face of door 22 and at these points a suitable wire or other stay such as 3D is also wound around the cable 28" to prevent slippage of members 42 and 43. The other ends of the strap members 42 and 43 are welded to and project downwardly towards the I-beam 8 and have welded to their other ends a horizontally disposed I-beam 44. On this I-beam 44, a pair of upwardly projecting bearings 45 and 46 are secured, in which is rotatably mounted a shaft 41. This shaft 41 has a pair of drums 48 and 49 fixedly secured thereon, around which are wound cables and 52, the free ends of which are connected to eye bolts 54 and 55 secured to the door 22 which is slidably mounted on the guy rods or cables 23 and 24.
The uprising bearing member 45 has associated therewith a pivoted dog or pawl 60 which is adapted to engage a ratchet wheel 6! fixed on the shaft 41 which will lock the net in extended position and'prevent its moving towards folded position under the impact of a person falling onto the net.
When it is desired to house the nets, of course this dog would be lifted from the ratchet wheel 6| and placed over against the other side of the ratchet wheel to permit the cables 5! and 52 to be unwound from the drums 48 and 49.
Each shaft 41 has fixed thereon a pulley 63 which has a V-belt 64 thereon which is also mounted on a V-pulley 65 on motor shaft 56 of an electric motor 51. Each electric motor 6'! has leading therefrom wires and II which lead to a switch 12 at any desired point in the building such as at the clerks desk of a hotel so that in case of fire, he can close switch 12 and move all of the nets to distended position, or, if desired, the switch 12 can be thermostatically operated to omit the personal element.
Mounted on top of the I-beam I6 is a bracket in which is rotatably mounted an idler pulley 1B for preventing the V-belt 64 from engaging the I-beam l5.
It is thus seen that I have provided a fire net associated with each side of a building which can be housed against the elements, but which nets can be moved to distended position by remote control or thermostatic control so as to provide a fir net anchored to the building which will be accessible for the occupants thereof in case regular escape routes are cut ofi.
If it should be desired to operate the mechanism by hand to extend the nets, as in case of electric current failure, I may mount on the shaft 4! a bevel gear 80, and a collar 8| may be welded. to I-beam 44 and a shaft 82 will rotatably penetrate shaft 44 and collar 8i and have a bevel gear 83 secured on its upper end, meshing with bevel gear 80. The lower end of shaft 82 has a fitting 85 secured on its lower end having a socket into which the upper end of a handle 88 may be releasably fitted to rotate the shaft 82. The handle 86 may be stored within the building or other suitable place.
In order to de-energize the motor 61 when the net is fully extended, I provide a fixed GQIIWQQ 9B on the exterior of the building and also a movable spring contact 9|, which contact Si is biased to engage contact 90, but contact 81 is extended into the path of door 22, so as to be engaged by the door 22 to move contact 9| away from contact 90 to break the circuit since these contacts are connected in series with wire 1 i.
In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being defined in the claims.
