Mason, Prairie Village, Kans., assignor to Mason Plastics Co., Inc., Kansas City, Kaus., a corporation of Kansas 4 4 Application in... 1, 1954, Serial No. 433,483 Claims. (21. 11s 4os This invention relates to structure for use in machines for coating articles with suitable substances such as plastic materials and has for its primary object the provision of an improved guiding assembly adapted to receive articles of irregular diameters and maintain the same substantially centered along a rectilinear path of travel so that a more even and uniform coating of the substance is applied thereto.
It is the most important object of the instant invention to provide a guiding structure adapted for immersion in the substance to be used to coat an article and having a novelcollect arrangement operable automatically to always remain in engagement with the article as it is advanced through the collet and thereupon through the coating substance, all to the end that the article is held centered, particularly with respect to a doctor plate used to wipe excess substance in the article.
An important object of the instant invention is to provide guide structure for use with coating machines of the kind contemplating advancement of the article through the substance so that an excess amount of the latter is always made available to the article, the guide including a resilient collet so arranged as to engage and hold the article against lateral movement at all times while it is being advanced through the substance.
It is an important aim of the instant invention to procide in a guide structure of the aforementioned character, a reciprocable segmented, resilient collet having a bore therethrough for receiving the article to be coated and including cam means for biasing the segments against the article at all times while it is rotated and advanced through the collet.
Other important aims and objects include the way in which a liner is provided to guide the article to the col let; the way inwhich the guide is utilized for releasing the parts which hold the collet in place; the manner of providing a spring bias on the collet to render the cam means effective in varying the diameter of the bore through the collet; the way in which an interlocking connection is provided to releasably hold the collet in place; the manner of feeding the coating substance to the article as it emerges from the outlet end of the collet and immediately prior to treatment by the said doctor plate; and the way in which all of the aforementioned structure is operably held in place within the substance by a specially formed guide body.

The field of coating articles of merchandise has increasingly expanded since the development of many new synthetic plastic materials because it has been found that such materials are capable of rendering various articles more resistant to wear, less subject to corrosion and other deterioration, stronger and more attractive.
In many applications advantageous results are experienced because of insulating properties of the coating substances. While the end results are extremely beneficial, it is most difficult to obtain an even, uniform coating of the plastic substances on the articles and such is necessary, not only from the standpoint of attractiveness, but utility. Voids, irregular surfaces and overlapping should be avoided as much as possible if the abovementioned results and advantages are to be attained.
Such plastic substances commence drying immediately upon exposure to the atmosphere and unless the coating is substantially uniform throughout, the surface of the article being coated, the drying and setting, will likewise be nonuniform resulting in many rejects thereby increasing the cost of the entire operation.
According to the principles of the instant invention, the article to be coated is advanced through the coating substance and, by virtue of such complete immersion of the article therewithin at least momentarily, an excess of the substance is directed to the: article so that there is always an assurance of a sufiicient amount thereof on the article prior to its being doctored by removal of excess substance.
Thus, as shown in Fig. l of the drawings, there is provided a container or vat broadly designated by the numeral 10 adapted to receive the coating substance, and when the same is in the nature of a synthetic plastic, it is preferred that the same be in a highly viscous,
gelatinous state, yet sufliciently fluid to fiow freely to the article through a plurality of passages 12 formed in an elongated, tubular guide body broadly designated by the numeral 14.
A removable collet broadly designated by the numeral 26, mounted in the body 14 is made of any suitable resilient material and provided with an integral, outturned, annular flange 28 on one end thereof, together with a frusto-conical head 30 integral with the opposite end of the tubular collet 26.
By virtue of the tubular nature of the collet 26 it is adapted to receive and guide an article 324 (Fig. 1) such as an elongated tube, rod, pole or the like, to be coated with the substance in container 10. The longitudinal bore through the collet 26 may be provided with an outlet end 34 of reduced diameter if desired, whereby to define the area of frictional engagement between the collet 26 and the article 32.
r a r am in 4 d. i pl ew t in body by pins or the like 46, surrounds the head 30. of collet 26 in engagement with the cam surface 40 which it complementally iits Cam ring 44 is provided witha seat 48for one end of a spring 50 coiled about the collet 26 Within the body 14. A pressure ring 52 freely movable within the body 14 has a seat 54 for the opposite end of the spring 50 and is disposed in surrounding relationship to the fiange 28 of collet 26. Pressure ring 52 is provided with a slot 56 for each pin 42 respectively, and a depression 58 on one face thereof registering with eachslot 56 respectively.
The said one face of pressure ring 52 opposite to spring seat 54, is also provided with a radial V-shaped groove 60 for each pin 42 respectively.
It is now seen that when the pins 42 are within the grooves 60 as shown best in Fig. 5 of the drawings, pressure ring 52 is disposed between the pins 42 and the spring 50, whereas the latter is interposed between the pressure ring 52 and the cam ring 44.
As the article 32 is advanced and rotated in the direction of the arrows shown in Fig. 1, it is guided into the collet 26 by a liner 62 fitted within the body 14 and provided with an article-receiving bore 64.
The liner 62 is provided with a cavity 72 at its innermost end having a diameter sufficiently great to receive the flange 28 and its pins 42.
Assuming the various parts of the guide assembly to be assembled in the manner shown by Figs. 1 to 6 inclusive, the operation is asfollows:
Through use of any suitable mechanism not herein shown, the article 32 is advanced rectilinearly and simultaneously rotated through the bore 64 of liner 6 2, thence through the collet 26, through the coating substance as the article 32 emerges from the outlet end 34 of collet 26, then through a circular opening ;74 of a dcctorplate E 76 and finally through an opening '78 in the outside ring 24. It is noted that the doctor plate 7'6 is carried by the body 14 within a cavity 80 and held in place against the inner face of wall 26 by the ring 24.
By virtue of the resiliency of the material from which the collet 26 is made, the segments 38 thereof will spring outwardly in response to areas of increased diameter in the article 32 as such areas slide along the outlet end 34 of the collet 26. In this respect it is to be pointed out that notwithstanding the fact that the article 32 is of a general uniform diameter, in many instances the diameter of the article 32 varies, and by virtue of the continuous bias of the segments 38 on the article 32 as it is advanced and rotated, collet 26 will always hold the article 32 substantially centered with respect to the opening 74 in the doctor plate 76.
In addition to the inherent resiliency of the collet 26 spring 50 maintains a constant yieldable bias thereon tending to shift the collet 26 toward the liner 62 whereby the diameter of the bore through the collet 26 varies,
Cal
depending upon the position of the head 30 within the cam ring 44.
The coating substance enters the body 14 through the passages 12 and is directed to the article 32 in excess between the outlet end of the collet 26 and the doctor plate 76 by virtue of the frusto conical configuration of head 30. Excess coating substance is immediately removed from the article 32 by the opening 74 in doctor plate 76 and, as the article 32 emerges from the opening 78 in ring 24, the even uniform coating of the substance on the article 32 commences drying immediately as it is subjected to the atmosphere.
It is extremely important to note that the entire guide assembly has been designed to accommodate articles 32 of differing diameters and to this end, the liner 62, the collet 26 and the doctor plate 76 are all quickly and readily interchangeable with like elements of differing sizes, V I
In making the change, removal of. the ring 24 releases the do'ctor plate ,7 6. The bolts 70 are thereupon retracted and the bolts 68 are used to force the liner62 inwardly toja point where it engages the pressure ring 52 and shifts the latter toward the cam ring 44, thereby compressing the spring 50. This releases the pins 42 with respect to the grooves 60, whereupon by grasping the head 30, collet 26 may be turned 60 to align the pins 42v with the slots 56. The depressions 58 tend to guide the pins 42 into the slots 56, whereupon the collet 26 may be removed in its entirety from within the body After removal of .the bolts 68, bolts 70 may be used to retract the liner 62 to a point where it can he slipped outv of the body 14.an d it is to be noted that all of these operations may be performedwithout removal of the body 14 from the container 10.
. ln replacingelernents 62, 26 and 76 of differing sizes so far as. internal diameters thereof are concerned, the steps .just above outlined are simply reversed.
