Karl Eisele, Belleville, N. J1, assignor to Camloc Fastener Corporation, New York, N. Y., a corporation of New York 7 Application November 18, 1943, Serial No. 510,756 15 Claims. (01. 10-86) This invention relates to a structurally and functionally improved apparatus for the formation of nut elements and particularly elements of this nature which include a bored and threaded body to be contained within a shell and with which assembly there is associated a fiber or equivalent washer or disc.
In its more specific aspects, it is an object of the invention to furnish a mechanism of this type which will be particularly useful in constructing or assembling nut elements of the type shown, and practicing themethod illustrated in the prior application for United States Letters Patent filed on June 23, 1943, in the name of J. Mills Summers, and identified under Serial Number 491,895.
It is a further object of the invention to provide a machine of this type and by means of which the several parts of'the nut assembly will be disposed in proper and predetermined relationship with respect to each other and will thereupon be staked or secured in an improved manner against relative shifting.
Another object is that of designing a machine in which the completely assembled elements will be positively ejected anddelivered; such delivery occurring without any liability of damage to the finished units.
An additional object is .that of providing a machine which may be capable of sequentially receiving the several elements which provide afinished nut unit and grouping these elements in a predetermined and desired manner with respect to each other.
Still another object is that of furnishing an apparatus of this character which will include relatively few parts, each individually simple and rugged in construction; these parts operating with maximum speed over long periods of time and with freedom from all diificulties, to furnish units as afore described.
With these and other objects in mind, reference is had to the attached sheets of drawings illustrating practical embodiments of the invention, and in which:
Fig. 1 is a fragmentary plan view of the dial plate or turntable of the apparatus;
Fig. 2 is a longitudinal sectional view taken along the lines 2-2 and in the direction of the arrows as indicated in Fig. 1;
Figs. 3 and 4 are fragmentary transverse sec tional views taken respectively along the lines 3-3 and 4-4 and in the direction of the arrows as also indicated in Fig. 1;
Fig. 5 shows in elevation and plan the several parts of the nut assembly which are to be staked by the present apparatus;
Fig. 6 is a sectional plan view taken along the lines 6-6 and in the direction of the arrows as indicated in Fig. 2;
Fig. '7 is a fragmentary sectional view taken through a portion of a dial mechanism forming a part of a machine which is intended to sequentially receive the successive parts of the nut assembly;
Fig. 8 is a view similar to Fig. 7 and showing the washer element in position within the shell of the nut unit;
Fig. 9 illustrates the body of the nut in posi- I tionupon the fiber washer; and 1 Fig. 10 is again a transverse sectional view' of the parts as shown in Figs. 7 to 9 inclusive, but additionally illustrating the mechanism whereby a predetermined and desired relationship of these parts is established.
With primary reference to Fig. 5, it will b As will be noted, the well portion I6 is preferably of non-circular configuration. A washer ll! of similar configuration is provided. This washer is preferably formed of fiber or similar material. The washer or disc iscentrally apertured as at 20; the inner face of this bore be ing unthreaded.
Still with reference to Fig. 5, a nut 2| is also provided. This nut has its bore threaded as at 22. It also has an external configuration preferably corresponding to the inner configuration of the well portion Hi. The edges of the nut are formed with grooves 23,v the base portions of which may be arcuate or substantially straight as desired.
As disclosed in the prior Summers application, the disc or washer I9 is disposed within the shell l5 and adjacent the base of the well portion. In turn disposed to overlie the washer is the nut 2 l The purpose of the present apparatus is that of establishing a proper position and relationship of these several parts and in staking the assembly so that subsequent movements of one part with respect to the other is prevented. This will result in the production of a unit which is compact and These are conveniently apertured to ready for use. At will be hereinafter apparent, the parts may be automatically assembled in the machine or else assembled prior to association therewith; a machine constructed in accordance with the present invention serving to properly dispose the parts of the assembly and secure them against movement. In the interest of simplicity of design, .itisa-inncertain respectssprefrreditoa group the-parts of the=--nut assemblies prior to:- their association in the machine.
Thus referring to Fig. 1, it will be seen that;: the numeral 24 indicates a dial. This.is.rotat-. ably supported as, for example, at 25above a bed plate 26 as shown in Fig. 2:v ThBidiaI'FZAriSJ-JHE I levers will be contacted thereby and separated. This will force the opposite ends of the levers inwardly. Such action will have the result of projecting the jaws or punches 34.
Aswill be appreciated, the jaws of these punch portions will be curved if an arcuate indentation is to be formed in the shell I5 (and if the groove niofithe nut. iszarcuate inzsh'ape) Ifjthatgroove is of another configurationr then the jaw portion of the punches will be correspondingly modified.
A plate 44 is disposed to overlie this entire assembly... Theplate has an opening of a configuration corresponding to the outline of the shell l5.
Thisippening iszaligned. with respect to the recess termittently rotated or indexedsanound'ltsrcentenr m i e t f w in conjunction t t point. This may be achieved by any desired type of drive. Likewise, by means of. a=suitable.drivei a head 2'! as especially shown in Figs. 2and 3 is caused to reciprocate.

Thereafter, the plungers 45 move beyond the eam l'l, whereupon they assume their fully retracted positions. Under certain conditions, it might'be. desired instead of assembling the parts of the nut unit prior to their association with this machine, they might be assembled within the machine and prior to the operations just described.
If such a result is to obtain, it is apparent that as shown in Fig. 'l-the shell might be delivered in any desired manner to the upper face of the; dial plate and so that the well portion l6 of theformer would be disposed in one of the. corre-. sponding portions .!Of. the latter. Thereupon, as shown in Fig. 8 a washer element l9 could be disposed within the shell. Subsequently and as illustrated in Fig. 9, a nut 2| could be positioned within the shell and upon the washer or disc l9. Following such a disposal of the parts, the tamping plunger 29 would operate in the manner heretofore described to assure a disposition of the washer and nut not alone proper with respect to each other but also with respect to the shell. Beyond this station the staking operation would occur.
From the foregoing, it will be appreciated that a mechanism is provided which, among others, will accomplish the objects specifically set forth in the preamble to this specification. It is also obvious that numerous changes in construction and rearrangements of the parts might be resorted to without departing from the spirit of the invention as defined by the claims.
