CABLE ATTACHMENT.

, Urgnal application iled August 24, 1921, Serial No. 495,059.

Divided and this application tiled September 13, 1923. Serial No. 662,404.

To all whom t may concern:

Be it known that I, JAMES F. REILLY, a citizen of the United States, residing at 4Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Cable Attachments, of which the following is a specification.

My invention relates to cable attachments, that is to say, to a device `adapted to be mounted upon a hoisting or power cable for ,the purpose of supporting the load or taking the strain thereof.

`In my previous application for Letters Fatent, filed August 24, 1921, Serial No. 495,059, of which this applicationL is a division, there is shown and described an in- `vention relating to trolleys or .traveling carriages for elevating and transporting` the buckets used in trench and other similar engineering operations, and having as one of the features thereof means for positively supporting the load in the elevated position while the same is being transported by said trolley or carriage.

Heretofore, in the use of hoisting and `power cables, considerable diiiiculty has been experienced in providing attachments for lsupporting the load and taking the strain which could be adjustably mounted upon 1the relatively stiffwire cables and which, when mounted at the desired place upon the loable, would ibe firmly Vheld against shifting 1vthereon. Various constructions have been 7 "employed, such as those embodying'the use yofsplitvsleeves, and securing means were .usually employed having projecting parts which were liable to foul on the other parts ofthe apparatus in connection With which the` cableis used, but such constructions were Vmore 0r less objectionable and unreliable inuse.

The principal object, therefore, of my ,"present .invention is to provide an attach ment adaptedto be secured upon afhoisting cable, in` apparatus of the character such, for example, as that set forth in my previous application for Letters Patent aforesaid, for

supporting the load which is carried by they hoisting cable, but which attachment, however, isalso adaptable for Aother purposes when mounted upon hoisting and power vcables for taking the strain therein.V A further object of my invention is to provide a device of the character aforesaid, with means for .adjustably securing the attachment to the cable whereby the same will be precluded from shifting with respect thereto when subjected to the strains resulting from the intended use thereof,

The nature and characteristic features of my present invention will bevmore readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which:

Figure l is a vertical, central section of a trolley or carriage adapted to travel upon an overhead trackway, with a hoisting cable shown in connection therewith, and provided with a cable attachment embodying the main features of my present invention, said attachment being shown in side elevation;

Fig. Q is a vertical, central section, enlarged, of the cable attachment shown in Fig. l of the drawings; `and Figg 3is a horizontal section thereof, taken approximately on the line 3-3 of Fig. 2. Referring now more particularly to Fig. l of the drawings, there is there shown a `trolley or `carriage embodying one type of apparatus in connection with which my present invention is adaptable for use. A detailed description of the construction, arrangement and operation of said trolley or carriage is fully set forth in my previous application for Letters Patent, Yhereinbefore referred to, the same comprising a suitable framework 4-0, preferably built up of structural shapes and plates, and provided at the upper corners thereof with means for supporting stud shafts 4t2, for journaling the wheels 43 which are adapted to run upon' the upper surfaces of the lower iianges of an l.lf-beam 13, said I beam forming a trackway uponwhich said trolley is adapted to travel. The framework 40 also carries means for supporting a shaft 45, upon which shaft a sheave ,46 is mounted, and over which sheave passes the hoisting cable 27 for elevating the buckets or other load, which may bel secured upon the" lower end of said cable 27 in any suitable manner.A

Journaled in eachlof lthe lower corners of the framework 40 is a transversely, arranged shaft 50, each of which shafts has secured thereto a dog or latch 51, A The dogs or latches 51 normally rest upon a bar 52secured to ythe framework .at each side,.soasto form positive means of support for the latches 51 when the load comes thereon,- as is more fully explained in my previous application hereinbefore referred to. The upper inner ends of the latches '-51 may be recessed, as at 53, complementa] tothe .shape lof :the -cable attachment 28, which comprises the essential novel `feature of my present invention. It Will, of course, be understood vthat .the particular manner ofoperation, as Wellas the specific construction', of the ltrolley or carriage above described formsno essential part of the presentinvention, vbut Ithe lsame is illustrated inconneetion-vvith the cable attachment 28 to shovvmoreparticularly one Way in Which theusame ,is kadapted to .be used. v

l The cable attachment 28, in the particular embodiment of my invention shown in the drawings, comprises `a member preferably spherical in lshape and adapted to be vadjustably .but firmly clamped upon the fcable. *F or .the purpose of clamping the attachment 28.at the proper location on the cable-27, the attachment 28 is provided with .a .verticalcentral hole or bore 29, through Which'the cable 27 extends, and there are also provi-ded interior recesses 30, off-set lon eachside of the central bore 29 (see Fig. f The cable 27 vis engaged at each of the olf-set recesses-30 by a lU-bolt-31, provided ivithnuts 32 threaded on its ends andseat- .fed ,in -recesses 83, whereby the ends of the {Ll-'bolts u31,.and the nuts 32 which are mountfedfthereon, Will not project beyond the outer .'spherical sur-face of the attachment 28. The `v`arrangement is such that, as the nuts 32 ,are advancedon vthe threaded ends of the U-boltsi'31, the cable vWill be deformed from lva straight lineand lsufficiently drawn Withi in {thehrecesses 30 to clamp the member 28 upon--thecable 27 .at any desired location.

HFor' the purpose of reinforcing the U- `bolts 31, `therefis provided, oppositeeach of lsaid bolts, a block 33, slidably mounted in alcomplementally shaped openingand held in position by means of a plug .34 which is threaded'in the member 28 and bears against the other end .ofthegblock 33.

the foregoing arrangement, there Will be'provided anattachment for cables which maybe .mounted thereon at any desired posiyftion, .which ,attachment is particularly y,adaptableforsupporting the load or talring the strain-in yconnection with `Wire and .,s-imilarstiff cables and-the like, Whichhvh'en n `lso mounted upon the cable, will be securely and lfirmly vheld against shifting thereon, .which is so constructed and arranged that the stresses Withinthestructure Will be Well taken care -of,and Which-is also characterized by lthe absencev of projecting parts Which Would interfere vvith the'coaction of the attachment with the other parts of the apparatus `in connection with which the sameis used, and which is further characterized by the integral formation of the main body portion of the attacluncnt.
