To all whom it may concern:

Be it known that I, SOLOMON GERMAN, a citizen of the United States, and resident of Monkton, in the county of Baltimore and State of Maryland, have made certain new and useful Improvements in Fire Shields and Extinguishers, of which the following is a specification.

This invention is an improvement in apparatus designed especially for the protection of buildings from fire and for use in extinguishing the fire; and the invention consists in certain novel constructions and combinationsof parts as will behereinafter described and claimed.

In the drawings, Figure 1 is a front elevation, and Fig. 2 is a side elevation or edge view of an apparatus embodying my invention. Fig. 3 is a detail longitudinal section, partly broken away, of one of the sectional telescopic uprights. Fig. 4 is a detail cross section on about line 44 of Fig. 3. Fig. 5 is a detail cross section on about line 5-5 of Fig. 3. Fig. 6 is a detail side view, partly in section, showing the connection between the sections of the uprights and the shield sections. Fig. 7 is a detail cross section on about line 77 of Fig. 3. Fig. 8 is a detail top plan view of one of the top platforms; and Fig. 9 illustrates the construction whereby the invention may be utilized for supporting a scaffold and for fire escape purposes.

In carrying out my invention, I seek to provide in connection with uprights, shield sections extending between the same and preferably made of fire-proof material, and adapted to protect the building, upon which the improvement may be used, from fire when an adjacent building is burning. As shown, the uprights A are composed of a series of sections A, A A and A the number of which may be manifestly varied as desired. These uprights are sectional and telescopic, and the uprights are adapted to be extended from the collapsed position shown in Fig. 3, to the extended position shown in Figs. 1 and 2, by fluid pressure.-

Thismay be air pressure if desired, or it may be preferably water, supplied through a hose B to a suitable connection A at the lower end of the lower section A, a drain cock A being provided to relieve the pressure when it is desired to collapse the uprights.

At the lower end of the uprights I provide pick points A which may, in the position of the uprights shown in Fig. 2, enter the ground and anchor the uprights in place, and to one or both sides if desired of the pick points I provide rollers A to engage the ground when the apparatus is tilted so the apparatus may be readily moved from point to point and then when thrown to upright position will be anchored by the pick po nts as shown and before described.

The sections of the telescopic uprights are provided at their upper ends with collars a, a a and a and each of these collars, except the upper one (1 is provided with the laterally projecting lugs a see Fig. 6 between which are secured the brackets G and O at the upper and lower edges of the shield sections O by means of a pin or bolt 0 passing through coincident openings in the said parts, as best shown in Fig. 6 of the drawing. By this construction the sections may be readily secured and may be conveniently released when desired, and in practice the sections may be applied as the uprights are extended by the application of fluid pressure, as will be readily understood from the drawings. The several sections of the telescopic uprights are also provided at their upper ends with inwardly projecting flanges a"see Fig. 3-which are abutted by outwardly projecting portions adjacent to the lower ends of the next inner sections to limit the opening movement of the uprights, and these flanges a may preferably be provided on the collars a, a a and a, as will be understood from Fig. 3 of the drawings.

At their lower ends, the telescopic sections, except the lower or base one, are provided with upwardly facing shoulders a on their outer sides, which are preferably provided by screwing the collars upon the lower ends of the tubular sections, as shown in Fig. 3, and above these shoulders I provide one or more bands a a and interpose packing rings a to prevent leakage between the adjacent tubular sections. This construction is duplicated throughout the series of sections, and is clearly illustrated in Fig. 3 of the drawings.

The lower or base sections A are provided at their upper ends preferably on their collars a, with lateral lugs d to which are pivoted the upper ends of the props D, which props are preferably made in sections with their lower sections D pointed at their lower ends and slidable at their upper ends upon the upper sections and provided with clamp screws D by which they may be held in any desired position. These props operate to steady the telescopic uprights in position when applied as shown in Figs. 1 and 2 of the drawings.

The upper sections a of the uprights are provided at their upper ends with lateral lugs E for guy lines E see Figs. 3 and 9and are also provided at said upper ends with rope pulleys F-see Figs. 3 and 9-for ropes which may be utilized for any desired purpose.

The collars a, a and a are provid'ed see Figs. 2 and 3with clamping screws G by which the sections of the uprights may be held extended to any desired extent.

At their upper ends, the upper sections of the uprights support at their upper ends the platforms H, which may be provided with hand rails H. These platformssee Figs. 1 and 3are provided centrally with openings coinciding with the bores of the uprights, and have on their under sides ring-like flanges H fitting over the collars a, and the upper ends of the top section A may be closed if desired by plugs I- see Figs. 2 and 9or where desired, nipples I-see Figs. 1 and 3may be screwed into the upper ends of the collars a and have their threaded ends extending above the platforms H to receive hose sections when it is desired to utilize the apparatus for fire extinguishing purposes.

The uprights are provided at their upper ends with the laterally extending arms J braced if desired by the strut braces J, and these arms are supplied at their outer ends with pulleys J near their inner ends with the pulleys J and 011 their outer sides between their ends with the pulleys J? and F. The pulleys J and J together with cooperating ropes j" and j may be utilized for raising an upper shield section C and for adjusting the same at an incline-see Fig. 2so it may be moved over an inclined roof, as will be understood from Fig. 2, in order to protect a roof from fire. The pulleys J, together with ropes 3' may be used for manipulating a scaffold L, when it is desired to use the invention in ordinary building operations, and the pulleys J and ropes 9' may be utilized [or raising and lowering an elevator car M, which may be utilized in building operations or for fire escape purposes, and when this elevator car is used in connection with the scaffold L, the latter may preferably be cut away at one end to afford an opening L through which the car may operate.

The shield sections 0 may be connected together by means of rings N, or other suitable devices, so the ropes F may be utilized to pull all of the sections G up after the uprights have been extended, or the said sections may be applied and connected from time to time as the sections are extended by the application of fluid pressure. These sections C may be made of sheet iron, or of any suitable material, properly covered with asbestos in order to render the same fireproof.

Iclaim 1. The combination substantially as herein described of the uprights composed of the telescopic sections operating one within the other and provided at their lower ends with upwardly facing shoulders and at their upper ends with downwardly facing shoulders and having above the upwardly facing shoulders packing rings and bands above the same whereby to prevent the escape of fluid between the sections, the lower section having an inlet for fluid pressure, props in connection with the lower section for steadying the same, means on the upper section for the connection of guy ropes, a lateral arm on the upper section, means in connection with said arm for raising and adjusting a shield section laterally over a roof, and shield sections operating in connection with the telescopic sections, substantially as set forth.

2. The combination in a fire shield, of sectional telescopic uprights and a shield composed of sections brackets at the upper and lower ends of the shield sections and means securing said brackets to the sections of the uprights, substantially as set forth.

3. The combination of sectional telescopic uprights pro vided with lateral lugs, fire shields corresponding to the sections of the uprights and provided at their meeting edges with brackets having flanges fitting between the lugs of the upright sections and a pin for securing; said flanges between said lugs, substantially as set forth.

4. A fire shield comprising the uprights spaced apart, the shield sections extending between the same and the platform mounted on and extending laterally from the uprights and means for adjusting a shield section laterally out below the platform, substantially as set forth.

5. The combination of the sectional telescopic uprights provided at their upper ends with the lateral arms provided at their outer ends with pulleys, a shield section and a rope operating in connection with the pulleys on the lateral arms for adjusting the shield section over a roof, substantially as set forth.

6. A fire shield comprising sectional telescopic uprights, means in connection with each of the sections of the uprights for securing shield sections, shield sections corresponding to said sections of the uprights, and lateral arms at the upper ends of the uprights and means operating in connection with said arms for adjusting a shield section laterally over a roof, substantially as set forth.
