Definitions

  • the herein disclosed pocket and projection means is provided.
  • Another specific object of the invention is to provide on a rigid-jaw coupler having an aligning horn, a forwardly projecting lug on the pulling jaw side of the coupler and a pocket on the buffing jaw side of the coupler which provide an anti-jackknifing function for said coupler when it is being coupled with an opposing similar coupler.
  • FIG. 1 is a perspective view of a coupler embodying the invention
  • FIG. 2 is a side view of a coupler shown in FIG. 1;
  • FIG. 3 is a plan view of couplers similar to the one shown in FIGS. 1 and 2 in a position of lateral misalignment.
  • FIG. 4 is a plan view partly in a horizontal section of two intercoupled couplers embodying the invention.
  • FIG. 5 is a plan view of two prior art couplers in contact prior to coupling
  • FIG. 6 is a fragmentary side View of the two couplers shown in FIG. 5;
  • FIG. 7 is a plan view of the two couplers of FIG. 5 j ackknifed horizontally to a position from which coupling is impossible;
  • FIG. 8 is a plan view of two couplers embodying the invention making initial contact under buff
  • FIG. 9 is a fragmentary side view of the two couplers shown in FIG. 8;
  • FIG. 10 is a plan view of two couplers embodying the invention showing the maximum horizontally angled position of the couplers which can occur during coupling operations;
  • FIG. 11 is a fragmentary vertical section of the pocket portion of a coupler embodying the invention when in 3,154,255 Patented Jan. 5, 1965 coupled relationship with a similar coupler that is vertically displaced relative thereto.
  • FIGS. 1-4 there is shown the head of a rigid-jaw coupler A having a bufi'lng jaw 4 and a pulling jaw 6. Disposed laterally and rearwardly of the bufiing jaw 4 is an aligning wing 8. Mounted on the underside of the coupler A is an aligning horn 10 having a vertical face 10c which faces in an oblique forward direction toward the center line of the coupler.
  • lug 12 Extending forwardly from pulling jaw 6 and forming an integral part thereof, is forwardly projecting lug 12 which is disposed adjacent the outer edge of the jaw. On the opposite side of the coupler in the wing 8 there is provided a pocket portion 14.
  • the lug 12 is of such a size and shape that it is readily received in pocket 14 of an opposing similar coupler. As shown in the various figures of the drawing, the lug 12 projects laterally outwardly with respect to the outermost lateral extremity, e.g., the jaw edge 6a, of the associated pulling jaw 6.
  • the pocket 14 is defined by a top wall 16, rear wall 18, bottom wall 20, an inwardly canted side wall 21, and an inner side wall 22.
  • the pocket does not have an outer side wall in the preferred embodiment, but nothing herein should be construed as limiting the pocket to the particular configuration illustrated.
  • the bottom wall 20 is sloped forwardly and downwardly relative to substantially vertical back wall 18. The slope to the wall 20 is necessary to permit the lug 12 of an opposing coupler to slide upwardly into the pocket during coupling operations.
  • the top wall 16 is sloped upwardly and outwardly to perform a similar function and to assist in gathering.
  • the aligning function of the lug 12 and pocket 14 supplements the aligning function of the aligning horn 10. Once in coupled relationship, the lug and the pocket also function as an interlock to maintain the two couplers in coupled relationship. The effectiveness of the interlock is determined by the amount of slack between the lug 12 and pocket 14 which can be altered to suit particular operating conditions.
  • the lug 12 is characterized by a top surface 30, bottom surface 32, an outer side surface 34, a front facing abutment face 36, an inwardly facing vertical surface 38 and an outwardly directed surface 39 continuing from surface 38.
  • the surface 39 is angled transversely inwardly and rearwardly relative to the center line of the coupler to join with the forward end of the surface 38 and thus provide an increased gathering range during coupling operations.
  • FIGS. 5, 6, and 7 there are shown two typical prior art couplers that are in vertically displaced relationship.
  • A designates the lower of the two couplers while B designates the upper coupler.
  • B designates the upper coupler.
  • the lug 12 is provided on the front face of the pulling jaw 6 essentially for the purpose of engaging a front face 42 oftlhewing 8 as shown in FIG. 9.
  • the lug 12 thus functions essentially as a spacing "means for maintaining the wing of one'coupler and'the' pulling jaw of the other coupler apart on one side of the center lines of the couplers, while the two couplers pivot with respect to a point along the horn surface 10a at the other side of the center lines.
  • the pocket 4 is provided with the further refinement that thepocket is tapered rearwardly and the lug is tapered forwardly with respect to vertical and horizontal planes so that the pocket of one coupler may cooperate with the lug of an opposing coupler to promote final aligning and, ultimately, interlocking of the couplers.
  • FIG. 3 illustrates another coupling condition under which the lugs 30 of two opposing couplers A and B prevent non-coupling of the couplers.
  • couplers cannot be installed, or at least used for any length of time, with absolute lack of slack in the connection thereof with the draft riggingof respective vehicles.
  • the usual condition is that the couplers are able to twist at least slightly and concentrically about their longitudinal axes. Engagement of the horns of two opposed couplers, as shown in FIG. 3, subjects both couplers to twisting forces which may displace the buffing jaw 4 of each coupler outwardly of the extreme lateral corner of the pulling jaw 6 of the opposed couplers.
  • the presence of the lugs 30 permits the couplers to twist to a minor degree out of good coupling attitude and be correctly gathered in a positive coupling path as illustrated by FIG. 3.
  • the herein disclosed invention overcomes this tendency of the couplers to jackknife outwardly by providing projection and pocket means thereon as will hereinafter be explained.
  • FIGS. 8 and 9 there are shown'two rigidjaw couplers embodying the invention making an initial contact under buff. It should be noted that the only point of contact of the vertically displaced couplers is betweenthe aligning horn 10 of couplers B, and the underside of wing 8 of coupler A as at y. As in the prior art couplers shown in FIGS. 5, 6, and 7, there is a tendency to pivot around this point of contact y and to j ackknife laterally in the direction of the arrow. However, before the couplers can jackknife, the forwardly projecting lug 12 on coupler A engages the wing 8 of coupler B as shown in FIG. 10.
  • lug 12 and pocket 14 supplement the normal aligning function of the horn 1t During the initial stages of contact, the aligning horn 1%) guides the two opposing couplers :into their correct position for coupling. After the couplers are substantially aligned, but not coupled, the lug 12 by seeking to seat itself in the pocket 14 guides the couplers during the final stages of coupling. Thus, during the latter stages of coupling, the lug and the pocket augment the normal aligning action of the coupler.
  • the lug 12 and pocket 14 provide an interlock feature that can by itself interlock two couplers embodying the invention disclosed herein, or supplement existing interlocking structure.
  • a car coupler of the rigid-jaw type comprising:
  • a head having a pulling jaw member and a bufhng jaw transversely disposed on opposite sides of the longitudinal center line of the coupler, said jaw and jaw member being interengageable with the jaw member and the jaw of an opposed similar coupler;
  • an aligning wing member extending laterally outwardly from the head at the rear of the bufling jaw
  • a gathering-andaligning horn mounted under the pulling jaw member and having frontwardly thereof an aligning surface sloping forwardly and downwardly; said wing member having a lower extremity adapted to slide upwardly and rearwardly on a similar aligning surface of an opposed coupler to effect vertical alignment of the couplers as the coupling thereof progresses;
  • said spacing means projects from the pulling jaw member.
  • said spacing means projects from the pulling jaw mem-- her
  • said wing member has a pocket for receiving the spacing means of an opposing similar coupler in coupled relation with said coupler.
  • said spacing means tapers forwardly and the pocket tapers rearwardly with respect to vertical and hori-- zontal planes to augment the gathering and interlocking characteristics of similar couplers during the coupling operation.
  • said spacing means comprises a lug having a forwardfacing vertical gathering surface inclined rearwardly and inwardly toward said center line of a length and disposition adapting it to be engaged by the buffing jaw of an opposed coupler at a position wherein the vertical face of the horns of opposed couplers engage;
  • said lug has a vertical abutment face forming a corner with said gathering surface and extends laterally outwardly from said corner.
  • said lug projects laterally outwardly beyond the laterally outer front edge of the pulling jaw member.
