I A. J. RICH. SECURING ATTACHMENT FOR FIRE ESGAPES.
Patented Jan. 24, 1893.
SAN FRANCISCO, CALIFORNIA.
ALFRED J. RICH, OF
SECURlNG ATTACHMENT FOR FlRE-ESCAPES.
SPECIFICATION forming part of Letters iatent No. 490,362, dated January 24, 1893. Application filed $epternber 28,189 2- Serial No. 447,162. (No model.)
in the wall pins. I also provide the step or bracket with collar 01, as shown, for the purpose of preventing the attaching or securing thimble running too far upon the limbs d. After securing the wall pins within the walls of To all whom it may concern.-
Be it known that I, ALFRED J. RICH, a citizen of the United States, residing at San Francisco,in the county of San Francisco and State of California, have invented certain new and useful Improvements in Securing Attachthe building,Isecure the step orbrackettherements for Fire-Escapes; and I do hereby deto by means of the thimbleE, which thimble 1s clare the following to be afull, clear, and exact provided with internal right and left hand description of said invention,such as will enscrew threads e,e,consequentlysaid thimble is able others skilled in the art to which it most adapted to be secured or screwed to the shank nearly appertains to make, use, and practice of the Wall pin and the same. step, and as turned the two are brought close This invention relates to an improved setogether. Thus firmly locking the step or curing attachment for fire escapes, which conbracket of the wall to the building. The colsists in the arrangement of parts and details lars C, and d, serve as steps for the thimble, of construction, as will be hereinafter more as clearly set forth in Fig. This thimble fully set forth in the drawings and descripmay be of any desired. shape so as to allow the tion, and pointed out in the specification. turning thereof readily.
The object of my invention is to provide an attachment which will permit of fire escapes being secured to the wall, after completion of building,without defacing same, as is now the case, and in providing an attaching device which shall be simpler in construction,less ex-v pensive, and more effective in its operation than any heretofore known.
Referring to the the fire escape as terminating in ladder F, which projects over the roof of the building. This ladder is secured to the roof of the building and the front wall thereof in a manner similar to the step or bracket. That is to say, the upper curved portion terminates in the left hand screwthreaded ends to which thimble E secures, and the lower end thereof is provided with inwardly projecting pins f, which are also provided with left hand screw threads in a manner similar to the steps or I have shown my escape as consisting of a series of steps or brackets, merely for the reason that the same permits less disfigurement to the face of the building, but, if so desired, an ordinary escape ladder may be used in lace of the steps or brackets, which ladder would run the entire height of the building. In case a ladder is used,the same is provided with a series of inwardly projecting pins or limbs f, which pins or limbs have left handed screw threads cut thereon in order to permit of the same being engaged by the screw threads of the attaching thimble. It will thus be noticed that my attachment applies equally as well to the ordinary ladder as to the steps or brackets herein shown.
The wall pin may be secured within the building either before or after its completion, but I prefer to secure the same after the wall has been built. In this case an opening or hole is drilled into the wall of less diameter than the diameter of the pin, consequently drawings forming a part of this specification, wherein similar letters of reference are used to indicate corresponding parts throughout the entire specification and several views. Figure 1, is a front view of a building, showing fire escape attachment thereon; and Fig. 2, a detailed view of my attachment,partly in section, showing the manner in which the escape is secured to the wall.
The letter A is used to indicate the wall of the building, and B the securing pin, which is secured therein. This pin is provided with inwardly and outwardly projecting shanks b, b, which shanks have right handed screw threads cut thereon. The inner and outer shanks I separate by means of the collar 0, which collar may have the face thereof either milled or roughened in order to permit of the wrench being secured thereon, for the purpose of screwing the pin into the wall.
In Fig. 1, I have shown the escape as consisting of a series of steps or brackets D,having the ends thereof inwardly turned in order to provide a limb d. These limbs are provided with left handed screw threads in contra-distinction to the right handed screw threads cut ICC when the pin is secured therein, the threads thereof cut their own seat within the wall. However, if it is desired to secure the pins within the wall while the same is in course of erection, the screw threads may be dispensed with and the same firmly held in place by the layers of stone or brick placed thereon.
Having thus described my invention, what claim as new and desire protection in by Letters Patent of the United States, is
1. In an attaching device for fire escapes, a
securing the steps and wall pin together, said thimble being" provided with internal right and left handed screw threads.
2. In a fire escape attachment, the combination with the escape ladder provided with inwardly projecting limbs, of the wall pin adapted to be secured within the wall, said pin provided with an outwardly proecting screw threaded shank, of the securing thirnble for forming connection between the ladder and wall pin, said thiinble being provided with internal right and left handed screw threads.
3. In an the combination with the wall with inner attaching device for fire escapes, pin provided upon the wall pin, provided with inwardly projecting limbs, said limbs being screw threaded to the reverse of the wall pin shank,and ble being provided with internal right and left hand screw threads. .7
In testimony whereofI affix mysignatu re in presence of two witnesses.
