Johnston, Indianapolis, Ind., assignor to himself, as trustee Application December 15, 1944, Serial No. 568,256 12 claims. (Cl. 24-205) l 2 The present invention relates to connectors for parachute harness, and its primary object is to manently connected a lanyard attached to the harness, so that' the connector will not be lost provide a simple, inexpensive, fool proof means for holding the ends of the various straps of a parachutist’s harness, _which means will never theless be readily and quickly actuable to release The base member I0 is centrally perforated as at I5 to provide a journal mounting for a rotary all of said straps, whereby the parachutist may instantly divest himself of the harness. Further objects of the invention will appear as the de scription proceeds. » when the harness buckles I4 are disconnected therefrom.> stem I6 which carries cam means, indicated gen erally by the reference numeral I‘I. Said cam means is formed to provide a plurality of cam 10 risers, one for each hook assembly, and indicated generally by the .reference numerals I8, I8', I8”, To the accomplishment of the above and re lated objects, my invention may be embodied in the form illustrated in the accompanying draw and I8,"’, disposed generally in a plane normal to the axis of the stem I6, and radiating from said axis. The riser I8 is‘formed at one end with i-ng, attention being called to the fact, however, a high portion I8a, and inclined downwardly to 15 that the drawing is illustrative only, and that ward the base element I0 to a. low portion at its change may be made in the speciñc construction opposite end I8b.

Similarly, Fig. 1 is a pla'n of my connector, parts being the riser I8' declines from its high point I8'a to broken away for clarity of illustration; its low point I8'b which is immediately adjacent a Fig. 21s a similar view, the operating disc hav notch IS’; the riser I8" declines from its high ing been removed; point I8"a to its low point IB”b which is im f Fig. 3 is a vertical section through the con mediately adjacent a notch I9”; and the riser nector, taken substantially on the line 3-3 oi I8”’ declines from its high point I8"'a to its 25 Fig, 4, and looking in the direction of the ar low point I8"'b which is immediately adjacent rows; ' a notch I9"'. ‘ È Fig. 4 is a transverse section through the con The upstanding perimetral wall IU’ of the base nector, taken substantially on the line 4-4 of element I0 is provided with a plurality of perim Fig 3, and looking in the direction of the arrows; Fig. 5 is a fragmental section taken substan 30 etrally spaced bores 20 which are internally threaded at their lower ends for the reception tially on the line 5--5 of Fig. 1 and looking inthe of screws 2| whereby the pad I I is secured to the rection of the arrows; base element, and for the reception of oppositely Fig. 6 is a fragmental section taken in the piane entered screws 22 which penetrate bores formed of Fig. 3 and showing the latch pawl in release ,- in a corresponding perimetral wall of a housing position; and element 23, said latter perimetral wall register ing with said upstanding wall I0’ and preferably, though not necessarily, being rabbeted at 24 to cooperate with the cooperatingly formed upper Fig. 'I is a similar section showing the parts in an intermediate position during engagement of a buckle with a hook and pawl. Referring more particularly to the drawing, edge of said wall I0'. The uppermost surface of the housing element it will be seen that I have illustrated a connector unit which comprises a base element IIJ to the under surface of which is secured a pad I I which may preferably be made of leather. The base member Il) is formed to provide a plurality of perimetrally spaced, upstanding hooks I2, I2', I2”, and I2"'. 23 is dished, as at 25, for a reason which will ap pear, and is centrally formed with a downwardly 45 _ While four such hooks are illustrated in the present drawing, together with four of each of the parts cooperating with said hooks, it will of projecting hub 26 providing a journal support 21 for the stem I6. At peripherally spaced points, said hub 26 is formed'with four downwardly-open ing slots 28, etc., and said slots, and their bound ‘ ing walls, are traversed by bores 29 in which may course be understood that any suitable number be mounted pivot pins 3l, all as is clearly illus trated in Figs. 3, 4, and 5. The uppermost wall of of hook assemblies may be provided, depending upon the particular harness selected for use. Ob viously, one hook will be provided for each har ness buckle. The base member I0 may further be provided with an eye I3 to which may be per 65 Pivotally mounted upon each pivot pin is a pawl latch, said latches being indicated by the refer ence numerals 32, 32', 32", and 32"’. Since these each of said slots is further provided with a tapped bore 30 for a purpose later to become apparent. 2,404,909 4 <3 four latch assemblies are identical, only one has illustrated in Fig. 3. Such an operation, how ever, would be extremely diiìicult for an unas sisted operator. It will be noted that the chan nel 41 is shown, in Fig. l, to have a clockwise extension 52 beyond the position occupied by the plunger 45 in Fig. l. That extension 52 is some been illustrated in detail, and only one will be de scribed. The latch pawl is provided at its outer` end with a radially opening socket 33, the outermost boundary of which is defined by an outwardly , and upwardly inclined surface 34. what shallower than the main body of the chan nel 41. Therefore, when the disc-‘40 lis'îreturned The cani sur face 3dr-is so proportioned and designed that'its outermost point is spaced beyond 'the ’uppermost surface 31 of the hook I2 yby a distance greater -from its release positionfit will'be brought to a stop at the point at which the bore 49 and the than the radius of the end portion of the bar socket 58 register. If, now, the end of the pin forming the buckle I4, for a‘reason which will `5I is pushed through the hole 48 in the disc 40 to appear hereinafter. `depress the plunger 45 somewhat against the tend Facing inwardly, the latch pawl 32 is formed ency of the spring 46, the counter-clockwise with a notch 35 receiving and 'snuglyembrac'ing i; movement o'f the dise 40 can be continued until the- cam riser I3.
