It is an object of the invention to furnish a unit of this character which may readily be 10 ‘manipulated to secure any number of materialA layers one to the other and against any probability of accidental displacement with respect to each other. A further object of the invention is that of fur- ' 15 nishing a coupling device, the parts of which willfunction lto permit of aready release of the layers from each other, it being understood that the coupling and uncoupling of the parts as speci fled in this and »preceding paragraphs may be 0 achieved, for example, merely by the employment _of a simple tool such as a screw driver. An additional object is that of providing a coupling device embodying relatively few parts. each individually simple and rugged in construc 25 tion, such parts being capable of manufacture by > more or less automatic machinery and when as sembled operating over long periods of time with freedom from all diillculties. With these and other objects in mind, reference ` 30 is had to the attached sheet of drawings illustrat - ing practical embodimentsof the invention and in which: - „ ` Fig. 1 is a fragmentary face view of layers of material and showing the cpupling in association I 35 therewith; ` Fig. 2 is a transverse sectional view taken along ~the line 2--2 and in the direction of the arrows of Fig. 1; u , ï H P Fig. 3 is a side view of the part as shown in Figs. 40 1 and'2; - this may be put are so numerous that it is im practicable to herewith schedule the same. Suf flce it to say that any number of installations n) wherein the coupling will be useful will occur to ~ anyone having knowledge of problems involving the connecting of material layers and especially layers of metal. ' . _Thus, _referring primarily to Figs. 1, 2, and 3, 15 the numeral 10 indicates a material layer to which >a second layer of material Il is to be coupled. These. layers are formed with aligned openings, i preferably >having the same diameter, and there extends from the inner face of layer ila flange 20 or collar I2, defining the edge of the opening formed in such layer. While, of course, .this collar might, if desired, be integral with layer I0, it is preferred, for convenience o_f manufacture, that the same form a part of a plate i3, secured 25 to the face of layer Ill by rivets, welding, or other wise. This collar is formed with a pair of splrally extending trackway portions, which areprefer-v ably continued through its body in the form of slots I4. ` 3o It is.. of course, apparent that the lengthoi.' travel of the slots I4 can be varied t& suit any set of circumstances, and will, in part. be depend- ’ ent on the length of travel desired for the stud I6 in each case. i " 35 Adjacent what might be termed the exit por tions >of the tracks or slots- Il, the edge of the _ collar presents indentations I6.

If, as shown, however, the rod I1 be a separate element. then the rod ends or projections I1 clear the entrance of slots I4, layers I 0 and II may be completely' separated. In the form of construction shown in Figs. 5 and 6, a stud 24 is employed and which, sim it is to be understood that in being applied to stud Il it shall be associated therewith in a man ner such that any future relative movements of ilar to the forms described in Figs. 1 to 3, has a head 25 and is encircled by a resilient ele these parts is precluded. ment such as a washer 26. This stud rotatably ' Ailixed to the outer end of stud I6 is a head 10 portion I8, having a diameter materially in ex-cess of the openingV of layer II through which its shank extends. interposed between this head portion and the outer face of layer II-.is a spring element I9 in the form of a resilient 15 washer and which will, when in locked position, urge the head Il inwardly, as viewed in Figs. 2 and 3. With this construction, itis apparent that stud I6 including the rod end I‘I is perma nently attached to layer II. This is also true 20 of the resilient element or washer I9 which will extends- through an opening formed in’layer II, but layer -III is in this instance extended rear wardly, as indicated at 21 and is furnished with an opening aligned with the opening of layer II and from the edge of which at diametrically op posite points projecting portions 28 extend. These portions may, of course. project entirely> 15 across the opening or, as shown, may terminate after they extend inwardly from the opening edge for a proper distance. If a cross bar is actu ally employed, then at least thebase portion of stud 24 should be hollow. Otherwise it suilices 20 -at all times remain in position encircling the \ that this base portion be formed with grooves shank of said stud._ The same will be true of 29 and detents 30 deiining guiding tracks func _collar I2 with respect to layer lil. tionally corresponding to tracks I4 and detents 'If now the end of stud I6 is introduced into- I5. 25 the opening of layer I0 and the rod ends are As a, consequence of this form of construction, brought to a position in line with the entrance it_is apparent that with the parts in the posi of slot or trackway portions I4 (and vthe con tion shown in Fig. 5, an operator, by rotating tinuations thereof formed in layer I 0), it will against head 25, may cause a projection on the be obvious that by rotating _stud IE the rod or part oi'- stud 24 to bring the projections 28, or projecting portion I1 will be caused to traverse the cross bar, to a position at which it no longer 30 trackway portion I4, thus carrying layer II to rests within the detent portions 30.

Finally, referring to Figs. 7 and 8, it will be .tion which may be conveniently manipulated. Therefore, element I9 will be compressed to a major extent, and portions I'I will ride along the inner edge of collar I2 and enter the de observed that layers ID and II are again pres 40 ent. However, in lieu of collar portion 2i, a tube 3i is ai'iixed to the inner face of layer III and has a spring 32 extending outwardly from pressions or'notches I5. Thereupon, by reliev its base. In these views the trackway portions ing the pressure resilient elementy I5, incident are providedl by grooves 33 formed in the inner to the continued outward thrust which it ex face of tube 3| and within which projections 34 45 erts, will cause projections I'I to ñrmly engage ' ride. These grooves, vas shown extend from the these indentations, thus locking layers I 0 and II surface of layer i0 and are continued in the against movement with respect to each other. form of notches in the edges of the opening Obviously, aready release of the parts may formed in such layer. A stud 35 is associated be eiiected by rotating stud I 6 in the opposite with layer II and has the heretofore described direction whereby projections I1 will move out headed portion 36, or its equivalent. The pro of the indentations and then by continuing to Jections 34 are either formed by the ends of a rotate said stud, the rod ends I1 or their equiv rod or may, as afore brought out, be integral alents will ride along the trackway portions I4, with the stud.
