MEANS FOR IMPREGNATING MATCH SPLINTS Patented Dec. 23, 1930V UNITED STATES PATENT oF-Flc's i CARL C. HAFERKAMP ANDV WILLIAM J. ELDER, 0F OSWEGO, NEW YORK, ASSIGNORS TO THE DIAMOND MATCH COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS MEANS ronrnrnnenarrne MATCH sPLrNTs Appiication med october 1s, 192s. serial No. 313,300.

This invention relates to match making machines, and particularly to means ar# ranged in coi-operative' relation to a match splint carrier `whereby the match splints borne by the latter are economically and eiectively impregnated with a 'solution of material adapted to render the splints-nonsplint carrier of a match machine 'and di-V rectedy toward [the travelling depending splints; means for supplying a solutionA of impregnatin'g material, 'and also air under pressure, to the said nozzle, and means for oscillating the nozzle in a Vplane parallel, 0r substantially so, to the path of the adjacent splints during thetravelV of the carrier.

In the preferred embodiment of the present invention the spraying nozzle is'i'nounted and adapted to oscillate in. frontof` a vertically extending portion of the carrier to the end that the so'lution'ivill be projected from thenozzletoward and `against the horizontally-disposed splints andthe opposing vertical faceof the carrier plates, thus permitting'the resulting moisture on the plates to flow. freely therefrom into4 a suitable drip pan and consequently minimizing the salt accretion and the corrosive action of; the solution on the plate. The pendant position of the spraying nozzleensures the `gravitation of the solution thereto from an elevated source of supply. It alsoenables the suspension of thernozzle from and directly below a horizontal'actuating shaft, thus reducing thestresses 1n the supporting arm of thel nozzle as Wel-l as in the shaft. ,More-Y over the use of a horizontal'actnatiiigshaft obviates the useof thrustbearings there for, and the location of the bearings and the actuating parts for the shaft above the nozzle, protects the -said bearings and parts frointhe; injurious ell'ects of `the salt solution ejected from the nozzle. In this construction there is provided for the spraying element a suitablecasing to Which access can befreadily had, and alsoL means whereby s'liver's'and imperfect splints blown from the carrier plates by the force of the spray esca-pe the nozzle and its operating' devices and fall directly upon a detachable screen Which is located above the drip pan, Whe'nce they can bereadily removed.

The invention also comprises novel features of construction and combinations of parts' ,wliereby other advantages are gained, as will be hereinafter described; the scope of the invention then being 'dened in the appended claims.

` 'Referril'ig tothe drawings, 10 designates-a portion otra 'splint carrier ot' a continuous match machine which carrier, comprises an endle'sschain of per'forated plates in which i the Ysplints are endvvise inserted and thereby rigidly heldin spaced parallel rows, This carrier in its progress to andabove `the usual paralfin tank 1l is looped Vover a pail' O .f spaced-apart rails 12pt generalugU-*formation supported by cross-bars 13, Carried by the sov ich

framework 14 of the machine. The tops of the rails l2 are preterably formed with gaps 15 into which entend a pair of idlers 16 that afford rolling` contact for the carrier. These idlers are loosely n'iounted on a cross-shaft l? supported by suitably-disposed brackets 18 on the framework. An arched plate i9 sujiported beneath the path of the carrier loop, in the vicinity of the idlers, serves to intercept and shed Waste materials which may fall from the carrier, thus preventing their dropping into the underlying mechanism. This plate 19 is affixed to cross-rods 20 mounted in and between depending lugs 2l on the respective rails 12. (See Fig. 4.)

The leg 22 of the carrier loop, with the rows of match splints proj ecting horizontally therefrom, travels upvvard in a vertical path, as seen in F ig. 4, such leg being guided and supported in suitable trackways hereinafter described.

Mounted to swing in proximity to and paralle with the path of the upwardly progressing splints, throughout the Width of the carrier, is a nozzle 23 by means of which a solution of impregnating material, such as ammonium phosphate, is edectively sprayed upon such splints throughout the Width of the carrier. rlhis nozzle is supported at the toot of a pendulous arm 24 fast on a horizontal rock-shaft- 25 having its bearings 26 in a suitable housing 27 on an L-frame 28 which is bolted to a pair of transverse frame bars 29. Hence, not only are the stresses in the supporting arm 24 and shaft 25 reduced to a minimum, but the nozzle, as Well as the shaft and its operating parts, is away from the path of slivers and broken splints falling from the carrier.

riChe nozzle is provided with solution and air inlet ports 30, 31, respectively, in operative connnunication with a discharge opening 32 from Which the impregnating solution is ejected by air, under pressure. The ports 80, 3l are connected by pipes 33, 34 with ports 35, 36, respectively, in a` flanged head 37 which, together With the arm 24, is bolted to a flange 88 on the rock-shaft 25. The port 36 has affixed therein a fiexible pipe or hose connection 39 which leads to a suitable source of air supply, and the port has afhxed therein a throat member 40 which depends from a bracket 4l bolted, as at 42, to the bearir housing 43 ofthe L-frame 2e. The throat member is connected by means of a pipe 44 with a solution supplying unit which is or may be of the character shown, and described in the patent aforesaid. Such unit preferably includes a tank 45 containing impregnating solution which is supplied thereto through a pipe 46 having a suitable shut-off valve 47. It also includes a roll 48 which rotating in the tank and its contents carries up a peripheral film of the solution and deliversit to an inclined trough 49, from Which it flows into a funnel 50 in communication with the pipe 83 and gravitates thence into the port 30 of the nozzle.

From the foregoingit will be seen that during the oscillation of the nozzle 23 air under pressure passes through the port 51 and across the discharge opening 32 of the nozzle, and by contact With the liquid flowing from the port 30 reduces the liquid to a. line sp1-a y or mist and projects it in that condition Jfrom the mouth of' the nozzle and toward and across the vertical splint bearing face of the progressing carrier.

The rock-shaft 25 and the roll 48 are concurrently actuated. To this end the rockshaft is provided With a crank arm 5l which is connected by means of a rod 52 to a crankdisk 58 on av shaft 54 which is geared with the shaft 55 of an electric motel' 56 supported on the L-frame 28. The shaft 54 is also equipped with a sprocket Wheel 57 which is operatively connected by means of a chain 58 with a similar wheel 59 on the shaft of the roll 4S.

During the operation of the match machine the moisture deposited on the face ofl the carrier plates by the spray fiovvs down such plates and drips into a suitable receptacle, thus minimizing the salt accretion and the corrosive action of the solution on the plates, as previously mentioned. This receptacle preferably comprises a pan 60 which underlies the vertical leg 22 of the splint carrier, the pan being provided With basal lugs 61 which are supported on brackets 62 on the framework of the match machine. In one Wall of the pan is a pipe fitting 63 affording a fluid passage leading to a lateral overflow pot 64. In this pot is an upstanding nipple 65 which is connected by means of a pipe 66 with the inlet of a suitable pump 67, the outlet whereof is connected by means of a pipe 68 with the solution supply pipe 46 at a level below the valve 47 of the latter. Hence during the 0peration of the apparatus the liquid flowing into the pan is continuously pumped back to the tank. The tank 45 is provided with an overflou7 pipe 69 connected with the pipe 66 so that the overflow from the tank passes to the pump and is pumped back to the tank (See Figs. 1 and 2.)

The pan 60 is equipped with a detachable rectangular screen 70 upon Which fall tlu` slivers, etc., blown from the carrier plates by the. force of the spray :from the Oscillati nozzle, which screen is readily removable for cleaning as occasion may require. The top of the pipe nipple 65 Within the overflow pot (,i-l is so positioned that the solution level in the drip pan is normally Well above the screen, thus preventing the crystallization of the impregnating salt on the screen and the conf-1cquent plugging of the meshes.

A suitable protectve casing extends from the drip pan to the top of the loop of the splint carrier, so as to enclose the adjacent leg 22 of the loop, and also the pendulous spraying element. This casing preferablyV comprises four substantial cornerv posts 7l, 72 adn-:ed to and rising Jfrom the respective sides ot the pan. One 'pair 7l of posts extend adjacent to and parallel with the bach of the carrier and terminate in curved portions 27?; overlying the adjacent portions oi' the track rails 12,'and the vother pair 72 are fastened at their upper ends to the extremities of the curved portions "7i-l, thus affording a. rigd skeleton trame. This frame supports Vthe side, front and bach walls respectively ot the casing, the sidewalls extending from the bottom to the top ot' the trame, and the remaining walls terminating at .lower levels as seen. The side walls are provided with upper and lower hinged door sections T4, 75, respectively, and the frontend bach walls 76, 77 are hingedly mountedv on the adjacent posts, thus enabling accessvto be readily had to the interior of the casing for purposes of inspection, repair, etc.

The posts 7l cooperate with spaced v cal guide-strips @"8 to atlord the traclrways hereinbetore mentioned 'lier the leg` ol the carrier loop -in its upward travel, which guide-strips are conveniently fastened, as at T9, to the adjacent side doors 75. l

As a simple and eiiicientV means to contribute to the supportA and guidance oi' the body of the vertically-moving leg of the carrier loop, ssaced-apart vertical guide bars S0 are arranged adjacent the path ofthe imperiorate front portionsiSl 6) of the carrier. These bars are fixed at their respective ends to horizontally-disposed U-bar 82 carried by the posts 72 of the casing, the upper bar being suspended by straps depeiiding from the supporting.brackets Si of the stationary guide-rails 12 previously described.

In order toiinininiize the amount of moisture and salt accretions onthe back of the carrier plates, inci ,ent to the spraying operation, ai vertically disposed'partition pla-te having a lnlsal'deilecting ledge 85 supported within the casing adjacent to and partiel *ith the bach oi the vertical leo' ot' the carrier loop, and a transverse troiigh 8G hat# ing` at one end a spout d? leading to the drip pan, is arranged below the partition 84. Any spray going through the oeriiorations of the carrier plates or between the gaps of adjoining plates runs down the partition and dri es into the trough 85, which trough iii-turn, discharges its contents past the splint carrier into the drip pan.

The partition plate 8l is yieldabl f supported on the adjacent door TS of the casing in such manner that when such door is closed the plate is caused to bear 'liatwise against the back of the carrier.` Accordingly the plate Si is connected to the door by a pair oi' pivoted links 88 having depending tails '8D adjacentthe inner side ot the door, which door when closed bears against the tails swings the linls in' a manner to press the plate Sil closeI to the opposing side Vot the carrier. (See Figs. Ll and y T he trough cl-t3 is preferably supported at its ends in pockets 90 termed adjacent the lower ends of the side posts il. it also susained by straps 9i which depend 'from a cross-bar 92 connecting the lower ends oil the posts 7l, which bar affords a convenient support for the hinges oli-an overhan;l f cover-section 98 for an adjacent project; portion of the dripfpan wherein theV splint carrier is flexed in its passage from a horizontal to vertical position.
