Patented Jan. 7, `1919.
To all whom t may concern:
Be it known that I, Jol-1N B. HORAN, a resident 0f Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Worlr-llolclers for Coated Articles, of which the following is a specification.
This invention relates to holders for coat `ed articles whichare to be coated and then subjected `to centrifugal action to remove surplus coating. `The device is particularly designed for holding galvanized metal articles while dipping and thereafter subjected to centrifugal action to remove the The object of the invention is to provide a holder for the purposespecified which is of simple construction, and wherein the various articles are kept separate, wherebya uniform coating `is assured.
rll`he invention comprises a device constructed and arranged as` hereinafter de scribed and claimed.
In the accompanying drawing, Figure 1 is a side elevation of the device; Fig. 2 is a vertical section thereof on the line 2-2 of Fig. 3 showing several articles to be coat ed therein and with a surrounding jacket; Fig. 3 is a plan view of the same;"`and Fig. 4 is a vertical section of the lower part of the device showing additional means for supporting the articles to becoated.
rllhe work-holder illustrated is adapted particularly for holding long articles, such as bolts, spikes, nails or other relatively long articles provided with an enlargement at one end, or unheaded articles, such as bars, strips, or the like. The holder comprises two members 1 and 2 suitably spaced apart and provided with a series of openings or holes 3 in line with each other for receiving the articles to be coated. These two members are illustrated in a form of circular plates or disks having holes punched therein, but obviously they can be of any shape or structure having alining openings for receiving the articles to be coated. These members are held in proper spaced relation to each other, by means of a number of tie rods or bolts 4, four such bolts being shown,
, which pass through` openings inthe disks and by means of their heads and nuts tie the disks together, the disks being held separated the proper distance by means of tubes surrounding said bolts. These bolts and separating tubes provide simple means for rigidly` holding the disks in proper spaced relation, and also enable the disks to be readily placed different distances apart, to`accommodate articles of various lengths, by`simply substituting longer or shorter bolts and separating tubes `than the ones illustrated. 1
These disks are provided with suitable means for attachment to the rotating member of a centrifugal machine. As shown thelower disk is provided with a round hole fori-the passage of the shaft 6 of the cen trifugal machine, and the upper disk is providedwith a square hole 7 which is engaged by the pyramidal end 8 of the vertical shaft 6. As the Centrifugal machine may be of any construction it is not il1ustrated and need not be described. Sufiice to say that the shaft 6 is rotated ata high speed, and when the holder is set onto it, it is also rotated at a high rate of speed, and the unbalancing due to the rotary action holds it firmly on the end of the rotating shaft, without any further attaching means. In the drawings the articles to be coated are shown at 10, in Figs. 1 to 8 being illustrated as bolts, which are slipped down through the alining openings in the disks l and 2, and are held from falling through by means of theirheads When coating bolts the disks will be spaced such a distance apart that the threaded ends of the bolts project entirely below the lower disk and therefore will not be liable to be battered or marred, and all excess metal is thrown oil' so as not to fill the thread.
For coating articles not provided with heads, other supporting means therefor are provided. Fig. 4 shows one arrangement for this purpose, in which a foraminous supply member 11 is supported below the lower disks and serves as a rest for the articles. Preferably this supporting member will be so formed that the articles rest on projecting portions or points so as to permit the coating material draining off. In case the articles are provided with holes through their ends, they can be supported by a rod er wire threaded therethrough.
Suitable means are also provided for lifting and handling the work-holder, this bev ing shown in the form of a loop or bail 12 varticles 'thereinto around therein and held therein for the desired time, andis then Withdrawn and carried to and set-downen the'upper end of the centrifuge shaft 6, whereupon the centrifuge is started, thus imparting a higlrrotary speed to .the holder and throwing the yexcess amount of coating material off lthe articles. A jacket 13 surrounding the holder Will be used to catch the excess coating material and prevent it being thrown into the room. Y
Since none of theWork-holdingholes are fat the axis of rotation, all of the coated articles are subjected tothe centrifugal action, which' removes the surplus coating material and leaves a smooth uniform coating there- Y -on. Since the articles are lnot in contactfat .iparts "of the articles are not'liablefto injury.
anytime,'eitherrduring dipping or While r0- tating, a veryl uniform coating is secured, and furthermore threads lor .other .delicate vVarious changes may obviously be made in the form and construction of the .partsvvithI out departing from the inventionas 'defined in the claims hereinafterrappearing.
AWhat I'claimis:V
l. A holder for articles Whiledipping-and subj ecting to 'centrifugal 1action, comprising va pair of lspaced members provided with alining means for holdingthe articles toV be coated separatedfrom each other, said -members being provided With means fory connece tion to a centrifugal machine.
2. A holder for articles While coating and subjecting to centrifugal action, comprising a pair of spaced members provided with alining openings to receive individual arti cles, said members being provided With means for connection to a centrifugal machine.
3. lA holder for articles While coating and subjecting to centrifugal action, comprising a pair of members provided with alining openings to receive the articles to be coated, and tie rods and separators connecting said members and spacing the same apart, said members being provided with means for connection to a centrifugal machine.
el. A holder for articles While coating and subjecting to centrifugal action, comprising a pair of members provided with alining openings to receive the articles to be coated, tie bolts and separating tubes connecting saidmembers and spacing them apart, said members being provided With means for connecting the same to the shaft of a centrifugal machine, and means on said device for the attachment of lifting mechanism.
5. A holder for articles While coating and subjectingto centrifugal action, comprising a pair of Aspaced members provided With alining openings'to receive the articles-to be coated, one of said members being .provided with a non-circular hole, in combination with a centrifuge shaft having a non-circular pointed end to engage said hole.
In testimony whereof, I have hereunto set my hand.
