for electrodepositing pipe couplings.
The main objects of this invention are:
First, to provide a novel and improved core for producing objects of irregular outline by electrodeposition, more particularly pipe fittings or couplings.
Second, to provide a multiple-part core of the type described for use in electrodepositing hollow objects of irregular outline.
Third, to provide a core of the type described of multiple-part construction, which is readily assembled prior to use and dismantled after the process of electrodeposition is completed.
Fourth, to provide a core of the type described which is simple in construction, economically manufactured, and easy to use.
Fifth, to provide a core of the type described capable of use in producing pipe couplings and fittings which are uniformly smooth on the exterior and interior surfaces thereof.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined in the claims.
A structure embodying the features of the invention is illustrated in the accompanying drawing, wherein:
Fig. 1 is a view illustrating the core of the invention with, the parts thereof in assembled position.
Fig. 2 is a view in longitudinal section more clearly illustrating the parts of the core of the invention in assembled relation.
Fig. 3 is a view illustrating the manner of form- 5 ing the core of the invention in an electroplating bath, a completed or partially completed electrodeposited article in the form of a T-coupling be ingshown thereon.
Fig. 4 is a view partially in longitudinalsection' illustrating the manner of removing the core of the invention from a fitting produced thereon by electrodeposition.
Fig. 5 is a view in longitudinal section of the fitting produced by the core of the invention.
the present invention.
This invention relates to a core for producing 'hollow objects or irregular outline, being particularly intended for the production of pipe couplings or fittings of irregular shape, such as T- couplings', etc. The core consists of a plurality of parts readily assembled by a few simple manipulations. and conveniently dismantled after 5 the process of electrodeposition is completed,
deformable material. Fig. 6' is a perspective view of the shoulderforming insert constituting a part of the core of The core illustrated is one adapted for use in producing a T-coupling and therefore has novel provision for forming the rounded shoulder between the stem and transverse member thereof, whereby the resultant electrodeposited coupling will be smooth on its exterior due to the uniformity of deposition of metal and similarly smooth on its interior due to the provision of a shoulder forming insert, the surface of which merges or blends with the other parts of the core in a novel manner.
In the drawing, the reference numeral i in general indicates the core of the present invention which consists of a two-part main or longitudinal member or section 2 having enlarged extremities 3, 4 for producing the female coupling ends or sockets of the resultant fitting. The core 2 has a reduced intermediate portion 5 integrally connected to the enlarged end 3 and provided with a furtherrdduced screw threaded extremity or nipple 6 adapted to engage the threaded bore 6| of the end portion 4 whereby the portion 4 may be removed at the termination of the electro-.
deposition. 1
The core 2 is transversely drilled and tapped.- in the embodiment illustrated, radially at a central point as indicated by the reference numeral 1 to receive the screw threaded end 8 of.the lateral arm or branch member or section generally designated 9. The said branch member 9 has an enlarged portion In for forming a female coupling end or socket on the fitting and a reduced neck portion H intermediate the said portion l0 and the threaded'end 8. I provide a shoulder I2 between the threads 8 and the neck portion ll intermediate the said portion I0 and the threaded end 8, which shoulder is adapted to engage the intermediate portion 5 of the member 2 whereby to properly position the members. The reduced neck provides an annular recess between the 7 members and is adapted to receive the resilient fillet or shoulder forming insert l3, which is preferably rubber but may bemade of any suitably This insert is illustrated in Fig. 6. It has flaring or shirt-like inner end portions with a concave elongated interior face l4 adapted for snug engagement with the reduced portion 5 adjacent the branch receiving bore therein. It is curved exteriorly at I5 from an annular shoulder l5! normally abutting the enlarged branch portion Hi to an annular feather edge I52 merging in operative position with the surface of the intermediate portion 5 of the main member of the core. A bore I53 in the insert receives the neckii to pcsition the insert operatively, whereby to complete the shoulder IS on a finished product I! electrodeposited on the core, as illustrated in Fig. 5.
The female coupling sockets referred to above are indicated by the reference numerals l8, l9 and 20. I
In Fig. 4, I illustrate a finished fitting and the manner of removing the core from the same after the process of electrodeposition is completed.
The section 9 is first removed from engagement with the section 2 by unscrewing or threading the former outwardly, suitable recesses 2| adapted to receive a spanner wrench being provided for this purpose. The end member 4 is thereafter removed by a similar operation, after which the rest of section 2 is withdrawn axially from the fitting as illustrated in Fig. 4. I provide threaded openings 22 in the various members of the core whereby the same may be suspended in an electroplating bath as illustrated in Fig. 3 and which may likewise be available of to withdraw the core members from the finished fitting.
As a final step, the shoulder forming, insert [3 is removed from the fitting by any suitable means, its resilience permitting it to be readily deformed for this purpose.
Prior to placing the assembled core as illustrated in Fig. 1 in the electroplating bath, the
same may be coated in whole or in part. with a suitable substance to facilitate the .depositing of the metal but it has been found that in cou-' plings of the smaller sizes particularly, it is unnecessary even to coat the insert as the deposition will throw across the insert where the other parts are made of metal. If desired, certain parts can be coated, that is, the exposed ends, to preventdeposition of metal thereon. ,The core might be formed of material other than metal, that is, non-conducting metal and properly coated.
The core as illustrated and described is simple in construction and economical of production. It is readily manipulated in use and results in the production of superior fittings which are uniformly smooth both on their exterior and interior. The shoulder forming insert i3 merges with the surfaces of the reduced portion 5 and member 9 in such a manner than there is no perceptible joint o'r'meeting line formed interiorly of the finished product and the various other parts are appropriately machined so that thejoints therebetween do not result in-the formation of ridges in the fitting. I desire to stress the fact that the surface of insert l3 merges for allpractical purposes with the surfaces of the core so that the effect is the same as if the latter were of one-piece construction.
I have illustrated and described my -improvements in an embodiment which is very practical. I have not attempted to illustrate or describe other embodiments or adaptations asit is believed this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
