CABLE-GRIP.
Specification of Letters Patent.
Patented July 16, 1918.
Application filed March 31, 1917. Serial No. 158,813.
ToaZZ whom t may concern:
Be it known that we, THOMAS J. CRAVEN,
-a citizen of the United States, and DANIEL This invention relates to cable grips, and.V
has for its object the provision of a simple and efficient coupling for connecting the terminals of ropes or cables together or to other i objects to be made fast' or engaged thereby,
in which provision is made for securing the end of the cable in looped formation about the object to be connected and confining the loop under the wedging pressure of a gripping jaw actuated by the tensile stress exerted upon the cable, and wherein the arrangement is such as to adapt the Orip or cou )ling to a large range of uses, enabling it to e readily adjusted for attachment or when in use and to be quickly released for disengagement.
A preferred structural embodiment of the essential features of the present invention is described in the following specification and illustrated in the accompanying drawings, in which:
Figure 1 is a view in side elevation of the grip coupling embodying our invention and showing the cable connected thereby as when in operation.
Fig. 2 is a central vertical section through the coupling in the connected position of Fig. 1.
Fig. 3 is a transverse vertical section `on dotted line 3 3 of Fig. 2.
Fig. 4 is a horizontal section on dotted line 4 4 of Fig. 2.
Referring to the parts of the device by the corresponding characters of reference throughout the views of the drawings, 1 represents the body of the coupling which consists of a hollow sheet metal casing formed with spaced parallel side walls joined together at opposite edges by opposed outwardly curved walls 2 and 3, and having openings 4 and 5 respectively in opposite ends thereof. The inner arcs of the walls 2 and 3 of the casing are formed to provide semi-circular bearing surfaces 6 and 7 respectively to coincide with and receive the respective leads 8 and 9 of the looped end of a cable 10 extended through the openings4 and 5 of said casing, the wall 2 of the casing being extended inwardly and upwardly of the opening 4, as at 11 to engage and position the entering cable in substantially central Vertical alinement with the body of the casing, and with the looped portion of the cable extending through the opening 5 thereof.
Pivotally mounted centrally upon a stud 12 anchored to extend transversely and substantially centrally through the parallel side walls of the casing is a cam shaped clutch or gripping jaw 13. This jaw, -which is adapted to swing or rock upon the stud 12 receives said stud through an elongated aperture 14 which ermits of a limited transverse movement o the jaw thereon, and the ends of the jaw are foi-ined with reversely opposed eccentric or cam faces 15 and 1G which are peripherally coneaved to conform with and engage respectively the inner arcs of the leads of the looped cable, as shown in Figs. 2 and 4.
It will be `noted. that the minor distance between the opposed cani faces of the jaw is such as to provide clearance for the free movement of the cable longitudinally through the casing when the jaw is in the normal position, as when there is no load or strain on the cable. To provide for normally retaining the jaw yieldably engaged with the leads of the cable, a looped spring l17, embracing a stud 18 anchored transversely in the opening 5 of the casing, is confined at its free ends between a second stud 19 and the lower edge of said. jaw at one side of its pivotal axis for exerting pressure thereon to crowd said jaw in a direction to carry the major portions of the cam faces thereof into binding engagement with said leads. A lifting pin 20 anchored in the body of the jaw and extending laterally and freely through arcuate apertures 21 in the side walls of the casing a'ords means by which the j aw may be rocked against the tension of the spring 17 to release the cams from bearing engagement with the cable and enable it to be drawn freely through the casing.
With the parts inthe position as in Fig. 2, in which the loop of the cable is shown as engaged within an eye or loop 22, representing the load or objectwith which the cable is to be made fast under tension, it Will be apparent that as stress is applied to the body and looped portions of the cable the tendency will be to draw the leads thereof in lopposite directions out of the casing, and
as these leads are engaged with the cams of the jaw under the crowding tension of the spring thereon, movement `of the-.leads will effect a corresponding movement of the jaw in a direction to firmly force said leads "into ,gripping engagement with the embracing walls of the'casing under the wedging pressure of the cams of said 1jaw. By this arrangement the gripping action of the yaw,
:aside fi'oim,tlie initialpressui'e ofthe spring' normally retainingit engaged with theleads ,of thefcable, is .automatically controlled by -thestress exerted upon,the.cable,hence, the
greater the load the Imore firmly the cable will be gripped, and when the strain therev=on .is relieved the lifting pin may be manipulated to rock and release the jaw and :enable the cablezto be .in the casing.
readily adjusted `with- Ve claim: l. A cablegrip comprising a hollow casing having opposed arcuate passages for the reception of the leadsof a cable, and ,a1 gripoino' 'awv ivoted within said casino` and h l H having opposed cani faces reversely engageable respectively with the leadsY of said Cable `to wedgingly confine the same against them wallsofsaid passages, said jaw -being slidable transverselyof said leads to equalize its clamping effect thereon.
2. A cable grip comprising a hollow casing having opposed arcuate passages vfory the lreception of the'leads of al cable,` agripping jawpivoted within said. casing` and. having reversely opposed cam 4.faces rotatably engageable simultaneously with the leads of said cable to wedgingly confine said .leads frespectively in said arcuate passages, andv yieldable means restraining said jaw rotatablyl to .normally retain said cams engaged with the leads of said cable.
3. A cablegrip comprising a hollow Acasing having openings in opposite ends thereof foi' the passage 'of a cable therethrough, a
vgrippiing -jawqiivotally and slidably supported in said casing and having eccentric freception ofthe leads of a,cableav gripping jaw pivoted vwithin said casingand having opposed cam faces lreversely. engageable respectively with the leads of said kcable to wedgingly confine the saine lagainst the walls of said passages,.said jaw having anelongated aperture embracing itspivotal axis topei'init lateral movement thereon, Vand means yieldably restraining said vJaw lrotatably to normally retain `the camqfaces thereofengaged withleads of said cable.
5. A cablegrip comprising@.hollow casing having opposed arcuate passages fointhe reception of the leads of a cable, agripping jaw pivoted to swing and to lmove transversely Within said casing ,and having reversely lopposed cam facesengageable .respectively with the leadsof said lcable to wedgingly confine the same :against the walls of said passages, a spring interposed between said casing and said jaw and acting on the latter to retain the Gainsthereof yieldablyv engaged with the. leads of .said cable, and a projection on .the jaw freely vextending through said casing and operable to retract said j aw against the tensionoffsaid spring.
In testimony whereof we sign-this, .specification.
