AApplication July A2%), 1944,5Sei2`1l No. 542735537 .3 Claims. `1
.'I'l'iisinventionrel'ates tothe art of' galvanizing, plating 'oricoatin'g .and refers more particularly. to 'las machine 'employing :a -compound rotary and swinging motion` of. a container free'ly suspended from 'a2hook,'for thefpurpose of shaking off surplus zinc :or 'other metal4 from galvanized 'articles of :varying sizes.
.Mass'production galvanizing 'of small, medium size and largerfarticles, 'such as nuts, Vbolts,'wash ers, household rhardware, Ithreaded rods and .the
likeis nowcarried-out by placing these articles l into 'ia .suspended perforated container and virnmersing this'containerintothe galvanizing bath. When'thefcontainerlis raised from the bath,"the galvanized articles carry large `surplus quantities ofthe coating fmetal. This :surplus -metal vconstitutes .waste andfit'clogs some-of theisurfaces of the articles, such .as Vscrew threads, "thus `necessitating rethrea'ding.
An object of .theipresent invention .is the provision of :a machine of great simplicity having only simplev rotary `motion of its `movingl parts, 'ye't adapted to impart .'a compound ,rotary swinging motion to-a quantity :of freshlygalvanized articles. for-` the purposeo'f shaking 'oli surplus coating and thus providing .anieven and uniform .layer upon `the articles.
Another object is the provision oacentrifugal type machine with abasket which .may be quickly and easily detached andreplaced by unskilled labor,so `that the machine may be used in the course of a galvanizing ,process for the purpose of shaking off excessivecoatingwhile it has not yet solidified.
Another object is to save a large percentage of metal wasted in a coating .process and to provide articles all the surfaces of'which carry a uniform even coating, thereby eliminating the necessity of rethreading articles which are provided With screw threads.
Other objects willv become apparent frornthe following specilication.
'In accomplishing. the objects -of the present invention it was found desirable to provide v"a body in .the nature. of a .container 'and a vertical shaft above the body terminating in a hook at about the top of the body. The perforated metal basket containing freshly galvanized articles is quickly removed from the galvanizing bath and suspended from this hook by va rigid, pivoted strap handle.
On revolution of the shaft the basket not only rotates with it but swings outwardly from the f anifeectedi through the perforations -in 'the baaket Lupon therinnier :walls `of the :container-like body. The metal iisy shaped'oi these Walls and isxready then fori-repeated use.
The invention will appear more clearly from theffollowing detaileddescription `when taken in. connection yWith -thel -:accompanying drawings showing, "by Way of example'agpreferred embodinientv of thefinventive idea.
lInithe drawings:
fFigurefl is :ia iront elevation-of .the machine.
:Figure f2 =isfa i-side `elevation :partially in #section to show the suspended perforated metalfbasket.
lFigure 3. is a :horizontal section :along the. -line S-Sofligure l.
vThe:machine yincludes a body Vll (Fig. 1).., with a door 5. The body 4 is to enclose the basket r6 (Fig. 2) rand supportsv the shaft frameA and brake. The shaft frame includes brackets or side legs. l -and 8,v .an upper main bearinghousing V9 between 'them (the-three members :having roughly the form of half an ovala-ttened-at rthe top, lor .an-inverted U) ,and-a tcrossmernber |.0,fconnect ing; thefside :legs Land 8, -abouthalfway up and comprisingithe lowervmain bearing housing I.;
Also -partfof -thefshaft :frame is the motor supporting -lejg |2. iFig. 2), extending `Vsidewise of the upper housing 9, and downwardto the :bodyand bracing the members 1"-and.8against belt pull;VV motor |3-fis mounteddn vertical position on 'fthe legal-2, itslfieetfbeing bolted yto -feet -|4` and l-.rformedon-leg l2.
The shaft 1.6, terminating :at its lower end' in alro'ok '1111, isfmounted in the housings 9 and and carries a pulley-f|-8,drivenfbyaibelt L9, which is driven by pulley 20 on the-motor.
:A fbrak-e shoe-2|V isjpivoted tol -anarm` 22, which. :is keyed uponV fa shaft V26, mounted -onstandardl27., gon the xlelt top-:side -of .the .body (looking in the fdirection of v-ligure l), and :a bracket C23,- which is mounted on 4leg 'Al-2 by `loolting its-footf24-'to-afiootZ-.S-rforrnedfon leg |52. Arm 42. is also:- lreyed fupon ythe shaft- 26 and "is pivotally cemented `.by rod 28 toangle arm 529 which .is pivoted. to.- atheoutside :lower portion of the body below standard 21. Arm 29 is pivotally connected by rod 30 to angle arm 3|, which is pivoted to the left side of the body at the bottom and near the front (Fig. 1) and bears a pedal surface 32 at its outer end. This assembly is thus adapted to transform pedal pressure into pressure of brake shoe 2| against pulley I8. An extension coil spring 33 connects brake shoe 2| to leg I2, and is adapted to disengage brake shoe 2| from pulley |8 when pedal pressureis relieved.
Figure 3 shows a semi cylindrical shield or inner wall 34, extending the height and width of the body interior and located in the rear half thereof. The body top consists of covers 35 of light sheet steel, which extend from the back of the body to a line about even with the point of the basket nearest the front, and have a U- shaped openingover the basket, slightly larger than the basket and with itsopen end to the front. Rigidity is imparted to this cover by two angle irons 36 and 31 bolted to it and to the body frame. A smaller cover 38 extends from cover 35 to the front and is cut out substantially the hook Il. Then the motor is started rotating shaft I6 and causing the basket 6 to rotate and also to swing outwardly from the axis of shaft i6. This compound rotation and swinging causes the excess particles of zinc or other coating metal, which are still in liquid or semi-liquid state and are located upon various surfaces of the articles within the basket 6, to be ejected through the perforations in the side and bottom of the basket.
The shield 34 collects these escaped particles which solidify thereon. Then they can be scraped'oi or otherwise removed by any suitable means.
The progress of the shaking off process may be observed through hole 39 at all times.
' The machine is stopped by shutting off power to the motor and a quick stop is provided by pressure on the pedal 32.
The advantage of this procedure is that from 40% to 60% of Zinc used in galvanizing is saved and that the articles receive a uniform even coating. The elimination of surplus coating makes it unnecessary to rethread articles provided with screw threads.
It is apparent that the illustration shown abovehas been given solely by way of illustration and not by way of limitation, and that the above described machine is subject to wide variation and modification. All of such variations and modifications are to be included within the scope of the present invention.
