William'Meyer, East Orange, *N.' "J;, as'signoir to Wheaton Brass Works, Newark, "N. J.,- a-corporation of New Jersey Application Qctober s, we sel-tel N 4,151,019 Q 1 Claim. (ct-24 125) lQl'dal xially into said bod 9. f m the: free Bend This invention relates to an improved cable connector device; andthe invention has referonce, more particularly, to a novel connector device for coupling a pull cable or the like to selected means des iredto be actuated or other- .wise served thereby.

The invention has for an object to provide a simple, inexpensive, strong, durable and easily manipulated connector device having at one end a novel means adapted to releasably grip .an end I portion of a pull cable so as to secure the same thereto, said device having suitable means at its opposite end for .attachment to means desired to be actuated or otherwise served by said cable,

.tion receiving opening or passage transversely in} tersected bya chamber within which is housed a movable snubber block through which the cable end portion extends, said snubber block having .a .screwthreadedshank to project from said chamber, and a manipulatable nut on said shank, said connector body having means to support the thrust of said nut, whereby movement may be imparted to said snubber block so as to deflect the engaged cable end portion and thereby strongly grip and anchor the same between the connector body and snubber block against axial movement relative to said connector body or displacement from its engaged relation therewith.

Other objects of this invention, not at this time more particularly enumerated, will be understood from the following detailed description of the same.

An illustrative embodiment of this invention is shown in the accompanying drawing, in which;

Fig. 1 is a top plan View, Fig. 2 is a side elevational view, and Fig. 3 is a bottom plan view of one form of cable connector device illustrative of and according to the principles of this invention.

Fig. 4 is a longitudinal sectional view, taken on line 4-4 in Fig. 1; and Fig. 5 is a transverse sectional view, taken on line 5-5 in Fig. 1.

Similar characters of reference are employed in the above described views, to indicate corresponding parts.

Referring to the drawing, the reference character indicates the body of the connector device, which may be variously suitably shaped, but preferably so as to provide at least one flat face surface, such e. g. as the flat top face surface Il. Extending longitudinally and centrally 12 th reof. is. a cable endtroztion r ceiving openits c rassase fi, seizedin diamete to snugly lit a cable. endg ertion l4 desired t bei s rted therein fcrattachrnent totsaidbody 1,0.

Means is provided to bridge the snubber block chamber l5, said means having an opening 20 through which the snubber block shank [8 projects, and said means being adapted to receive the thrust of the nut l9. .Said means, as shown, is constituted by a. separate perforate Washer 2| of external diameter exceeding that of the chamber 15; it will be obvious, however, that a chamber bridging means to bear to thrust of the nut [9 may optionally be provided as an integral part of the body H) or as a separable part thereof in the form of the washer 21 as shown. Preferably a lock-Washer 22 is interposed between the chamber bridging means and the nut H), which serves, when the nut is turned home, to securely hold the same against loosening and relaxation of its thrust against said chamber bridging means.

Preparatory to applying a cable end portion M to the connector body l [l for secured attachment thereto, the nut I9 is loosened and outwardly moved on the snubber block shank l8 sufficiently to permit the snubber block I6 to be inwardly moved to a position adapted to bring its cable passage I'i into aligned relation with the cable end portion receiving opening or passage [3 of t through the cable passage I! of the snubber block I6. After the cable end portion I4 is thus applied, the nut I9 is turned home on the snubber block shank I8 so as to thrust against the lock-washer 22 and bridging means or washer 2 I, whereby to transmit to the snubber block I6 an axial movement which is perpendicular to the axis of the applied cable end portion I4. This results in an offsetting movement of the snubber block I6, which moves its cable passage I1 and the cable end portion part extending therethrough out of alignement with the receiving opening or passage I3 of the body I and the cable end portion parts lodged therein, thereby defleeting an intermediate part of the cable end portion so as to snub the same between the snubber block and the adjacent opposite internal end edges 23 of the receiving opening or passage I3 formed at the junctures of the latter with the sides of the chamber I5, and thus firmly gripping and holding the cable end portion against withdrawal from the connector body ID, or in other words, securely anchoring said cable end portion to the latter (see Fig. 4) Since the nut I9 bears against the lock-washer 22, the latter securely holds the same against loosening and consequent relaxation of the grip of the snubber block upon the cable end portion.

It will thus be seen, that a very simple, easily manipulated, and yet securely held attachment of the cable end portion to the connector body I 0 is assured, and yet an attachment which may be easily released when, for any reason, it may be desired to disconnect the cable from the conmay comprise a clevis formation 24 to engage a link 25, lever or other mechanical element to ble to be entered therein, said body having a chamber extending therethrough in direction perpendicular to said flat face surface thereof, the

axis of said chamber intersecting that of said cable end receiving passage, a snubber block axially movable in said chamber and provided with a transverse cable passage initially alignable with said cable receiving passage of the body, said snubber block being of substantially less crossthreaded shank extending from said snubber block to project exteriorly beyond said flat face surface of said body, a perforate bridging Washer having an external diameter substantially exceeding the diameter of said chamber, whereby when abutted against the flat face surface of said body to bridge the mouth of said chamber, saidsnubber block shank extending through said bridging Washer, and a nut threaded onto the free end of said shank, said bridging washer being adapted to purchase said nut when the latter is screwed down on said shank, whereby to draw outward the snubber block to perpendicularly offset relation to the cable axis and thus snubbingly bend portions of the cable lying between the chamber so as to grippingly bind said cable between the block and body.
