Be it known that l, Aenrn l). Mamas, a citizen of' the United States, residing at Houston. in the county of Harris and State of 'iexas,have inventencertain new and useful Improvements in Elevators. of which the following is a specification.

My invention relates to new and useful improvements in elevators.

The object of the invention is to provide a device of the character described. composed of tubular telescoping sections forming a complete unit within which fluid pressure may be introduced whereby the device may be elevated or lowered correspondingly as the pressure is increased or diminished. The device is specially adapted to be used as a movable elevator which may readily be collapsed and will thus occupy small space and may be easily moved from place to place.

With the above and'other objects in view, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a side elevation, partially in section, of the complete device. Fig. 2 is a side elevation of the device completely extended and showing guy wires for supporting the same secured thereto and such as would be used for a wireless station and like purposes. Fig. 3 is a side elevation of a rick. Fig. 4 is a plan view of a spider forming the top of said derrick and connecting the elevators together and Fig. 5 is a side elevation partially in section, of the base upon which each of the derrick clevators is mounted.

Referring now more particularly to the drawings wherein like numerals of reference designate similar parts, in each of the figures. the numerals 1. 2 and 3 refer, respectively, to the base, intermediate and top sections of the elevator which telescope numeralspthe section 3 telescoping within the section 2 and the section 2 telescoping within the section 1 in the manner hereinafter to be more explicitly set forth.

The bottom section is secured to a suitable base 4 which in turn may be secured to any suitable support for the elevator. The

' the upper ends lower ends of the sections 2 and 3 are en larged so as to fitclosely within the re spective sections 1 and 2 and these enlarged ends are provided with a plurality of annular grooves 5 provided to receive suitable packing rings 6 which are provided to render the joints between said sections impervious to fluid passage. The upper ends of thesections. 1 and 2 are provided with annular inwardly extending shoulders 7 which, respectively, fit closely around the respective sections 2 and 3 and form bearings therefor and engage,. respectively, against the enlarged lower ends of sections 2 and 3 and prevent the sections from complete disengagement from each other, and

of sections 1 and 2 are outwardly threaded and receive the respective nuts 8 and 9 between which the annular rings or flanges 10 are secured. These flanges are provided with marginal perforations 11 around the edges thereof through which the guy wires 12, for supporting the elevator, may be passed in order that they may be secured to said flanges. A similar flange 13 is. secured at the top of the section 3 between the nuts 14 and 15 for a similar purpose to that of the flanges 10. The upper end of the tubular section 3 is closed by means of a plug 16 so as to prevent the escape of fluid pressure therethrough. The lower end, of the section is also inclosed by means of {129511) 17 which is secured there over and'a completely inclosed chamber is thus provided within the telescoping sections. Fluid pressure, either air, steam or by draulic. maybe introduced from any suitable compressor through the orifice 18 and the telescoping sections thereby fully extended. It is obvious that the amount of extension an easily be regulated in accordance with the amount of pressure produced.

Inter-posed between the enlarged lower end of section 3 and shoulder 7 of section 2 a strong coil spring 25 which surrounds the section 4. and is provided to break the shock-in caseof sudden extension.

This device may be used as a collapsible stein for a wireless station as shown in Fig. 2 or it may be used as an elevator and when used for the latter purpose is specially adapted for the purpose of rescuing persons rom tall buildings or to elevate firemen to upper stories in cases of fire and. will be found specially usefuhfor this purpose insurface.

asmuch as itcan be readily collapsed and quickly transported to the place where the rescue is to be effected or the flames are to be extinguished.

It is sometimes desirable to use a plurality of these elevators in conjunction in the form of a derrick, in which case they should each be mounted upon a universal hearing, shovn in Fig. 5 and have their upper ends connected to a spider 19, shown in detail in Fig 4. These bearings include a base having: a socket therein. The socket is provided to receive a hollow ball shaped casting 21 having a ground outer This ball is provided with a threaded neck 22 upon which the lower end o't section 1 is screwed. At the bottom of the socket is a chamber with which the Fluid compressor communicates and which in turn communicates with the interior of the ball 21. The fluid compressor communicates with the socket chamber either throug'l'i the passageway 23 in the side of base 20 or through the bottom thereof through orifice 24-. It is to be understood that when either the passageway 23 or orifice 24 is used for the admission of fluid pressure the other of said passageways should be closed.

It is further to be observed that when the elevators are used separately and not in the form of a derrick, as shown in Fig. 3, they may be hingedly mounted upon their base, as shown in Fig. 5 and not upon the rigid base shown in Fig. 1..

What I claim is1- 1. A device of the character described composed of a plurality of elevators each being composed of tubular telescopingsections, a base for each elevator upon which said elevator is hine'edly mounted, a spider bingedly securing together the upper ends ot said elevators, each of said elevators being); provided with an orifice tor the ad mission of fluid pressure therein.

A device of the character described composed of a plurality of elevators, each being composed of tubular telescoping sections, a base for each elevator upon which the same is hingedly mounted, a spider having' radiating arms which are hingedly secared to the upper ends 01": the respective elevators and which secure said upper ends together, each of said elevators being provided with an orifice :tor the admission of fluid pressure therein.

in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
