TOOL FOR DETAGETNG OBSTRUCTIONS FIEtOllE ELEd'I'RIC-WIRE CONDUITS.
To all whom it may concern Be it known that I, MAURICE BLUMEN- THAL,-EL citizen of the ,United States, and residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful ,Improvementsin Tools 7 for Detaching Obstructions from Electric-' Wire ConduitsJof which the following is a specification, such as will enable those skilled in the art towhich it appertains to make and use the same. i I I This invention relates to tools. or instruments for detaching obstructions from the interior of electric: wire conduits used for telegraph, telephone and other purposes,
and which are usually employed inconnec-j tion with what areknown as jar rods? which are usually composed of detaohablyj "connected parts, so that the length thereof may be increased or decreased as desired,
said rods being adapted lto be detachably connected with the toolor instrument; and
the object thereof is to provide an improved tool or instrument of this class which issimple in construction and effective in opera tion, and particularly designed for use in conduits which are rectangular 1n crosssection, and in either what are called single or multiple conduit-s, afurther objectbeing.
to provide a tool or instrument ofcth e class specified with improved means for recover.1
ing such a tool or instrument, or removing it from a conduit, if-at any time it should become'detached from the handle or jar rod v i The invention is'fully disclosed in the following specification of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which :s
Figure 1 is a plan view showing one form of my improved tool or instrument ;--Fig. 2,
a sectional side view thereof-;Fig. 3 a cross section on theline 33 ofFig. l;-Fig. i a cross section on the line H of Fig. 2; Fig. '5 a View similar to Fig. 1, but showing a modification ;Fig. 6 a cross section on the line 66 of Fig 5.
In the practice ofmy invention, I provide a tool of the class specified, comprlsing a i body portion a which is oblong and boxshaped in cross section, or composed of a bottom a and sides a and both ends ofwhich are open, as shown at a and a The Specification of Letters Pafint. hpplication fi1edJfanuary 14, 1914. Serial No. 811,988,
ily understood.
Patented se t. 22, 1914.
open enda is provided with a handle shank b which is rectangular m cross SECtlOIll and preferably square, as shown in Flg. 13, and
' as clearly indicated in Figs. 1 and 2, and the inner endof said shank is provided with, or formed into aplate b which is riveted to the bottom a? of the body of the tool, as shown at c, and the outer end of the shank b is provided with agcircularthead' If having.
threaded bore, 6%, and at (AT have shown 3 one part or section of a handle or jar :rod, provided with a; screw'threaded extension cl adapted to be screwed into the The end of thebottom d of the end of the tool, opposite the handle shank b isbeveled downwardlyto provide a cutting edge a, and thecorresponding-endsofthe sides a are also preferably provided with similar cutting edges 647, and this completes the tool, as far asitsuse for the purpose of removing or'loosening obstructions from the interior'of conduitsof the class specified are concerned,,it being understood that in this operation, or in this use of the tool, the said tool is manipulatedoroperated in the same manner as otherdevices of this class. f In order to provide means to recover a tool ofthis class when lostin a conduit, or accidentally detached from the handle or fjar rod, in the operation thereof, I pivot in the top part of the open and cutting end of the tool, or the body thereof, as shown at e, a hanger f which is adapted to serve as a pick up and when a tool of this class is dost in a conduit, or accidentally detached from the handle or jar rod in the oper ation thereof, another and similar tool is used as a recovery tool and is passed into the conduit in such manner that the head 6 of the shank of the losttool will pass into the open end. of the recovery tool, in which operation, the hanger f is swung inwardly or backwardly by the head 6 of the shank of the lost tool, and in the outward move- 'ment or withdrawal of the recovery tool, the
hanger f therein will catch against the head b 'of the lost tool, and the latter may be withdrawn from the conduit, as will be read- The construction shown in Figs. 5 and 6 is the same as that shown in Figs. 1 to 4 inclusive, except, that in place of the hanger f, I secure to the inner side of one side of the body of the tool, as shown at g, an inwardly and cilita'te the connection of the handles or jar rods with the heads of said shanks,
backwardly directed spring h which will operate in the same manner as the hanger if, in the operation of recovering a tool of this class, when lost in a conduit, or detached from thehandle or jar rod.
' From the foregoing description, it will be seen that all the forms of tools shown are provided with 'shankswhich are rectangular or square 1n cross section and provided with circular heads having screw threaded sockfets,-- and the object in providing shanks Which are angular In cross section is to fain which operation the tool or tools, may be placed on a table or on the grounol,and a spanner or similar device may be passed down over the shank or shanks, and the tool or tools held stationary, while the handles orjar rods are being screwed into the heads of said shanks, and a reversal of this operation will detach the handles or ro'ds when necessary.
It will also be seen that in all the forms of construction the body of the tool is rectangular in cross section and in the construction shown in Figs. 1 to 6 inclusive, said "body of the tool is rectangular and boxshaped in form and is open at both ends,
and theseforms of construction facilitatetheuseof a tool of this class in a conduit which is angular in form in cross section, and the box-shaped form of thetool also facilitates the removal from the conduit of obstructions of various kinds and classes after they have been detached from a wall or walls of the conduit by reason of the fact that said obstructions Willcollect or may be collected in the body of the tooland withdrawn from the conduit with the tool.
' Having. .fully; described, my invention,
what I claim asnew and desire to secure Letters Patentz q I 1. A conduit cleaning tool of the class described comprising a body portion having a jar-rod coupling at one end andthe oppositeend of-whichis provided with a cutting edge, and with a catch device adapted to engage thevcoupling of a similar tool lost in a conduit. 1 a
2. A conduit cleaning tool of theclass described, comprising an oblong box-shaped body portion open at one end and'provided with a. cutting edge, the opposite end being provided with a jar rod coupling, and the open end beingalso provided with a catch device adapted'to engage thecoupling of a similar tool lost in a conduit. 3
3. -A conduitcleaning tool of the class de- I scribed, comprising an oblong .body portion rectangular in cross, section. and box-shaped in form and open at one end and'provided with a cutting -edge, the opposite endof the I tool being provided with a jar rod coupling head, the open end being also provided with a pivoted catch device adapted to engage the coupling head ofia :similar tool lost in a conduit.
In testimony that I claim the foregoing copies or this patent ma y beobtaind for five cents each,
by addressing the Commissioner -of Eatnts,
MAURICE BLUM/ENTHALL
