UO'NNELLY,

a citizen of the United States, and resident of Barbertom in the county of Summit and State ofOhio, have invented certain new and useful Improvements in Splint-Drying Means for Match-Machines, of which the following is a specification.

This invention relates to means for dryin match splints, more particularly splints W ich have been impregnatedvvith a $0111 tion of a chemical or chemicals which reflder the splints non-glovvingafter the same,

,. as finished matches, have been ignited and the flame exting'tiished.

The invention. is especially ada t ted for use in connection With, or as an at achinent for, that class of continuous match machines wherein the splints are progressively 'set in parallel rows in an endless carrier and thereby transported through the matchmaking ath, and in that relation it has been primarily designed to carry out in an economical and elficient manner the splint drying step of the process described in Letters Patent of the United States No. I,O'44,1 5 3,' dated November 12, 1912. Such process, briefly described, consists in impregnating the splints with a solution of chemic l? 0f the character above mentioned, and then subjecting the Wet impregnatedsplints, held in spaced relation to each other, to the action of a bath of material which is impervious to Water, the said bath being maintained at a temperature suliicient to expel the solvent from the splint-s in the form of steam or vapor.

My invention concerns tlle operation of subjecting the splints to the action ofa bath of highly-heated granular material, such as metallic pellets, in a mannerto effect the rapid and thorough drying of the splints; and, broadly considered, comprises ,a struc: ture wherein-the said material is fed in a continuous stream to and along the p'ath of the Wet splints as the latter are 'elled spaced relation to each other-by t e splint carrier.

The invention also comprises' various novel features of construction and operation whereby advantages are secured,'as Will be hereinafter described and claimed. ,1 In the drawings Fi 're 1 is a sectional plan of a drier, enibo ying a good form of invention, certainparts being. broken away and one of the bottom plates of the.

drying trough being removed in order to expose elements otherwise concealed. In this view a" fragment of the splint carrier is indicated.- Fig. 2 is a full longitudinal iierticel section 'ofthe apparatus, as on the line 2--2 of Fig. 1; the impregnatin tank and a part (if the splint carrier as oaded with s ints, being Shawn. In this view the stream of granular drying-material is illustrated. ,Fig'. 3 is a' similar section, as on the line 33 of Fig. 1; the Wall of the chambered section being broken away to expose p'arts (if the burners and their adjuncts. 4 is a transverse vertical section of. the

F 7 is" a transverse horizontal section through one" end of the apparatu as onthe Hes 7--7. of F ig". 21 Fig. 8 is a transverse section thrbngt the rotary electro-magnets and tlfeifiadjtinets, as on the line 88 of Fig. 2. Fig. 9 is a detai1',-enlar ed, of the cdntaet rings and-brushes of t e electromagnets. Rig, iOis a sectional detail of the oiiterend of one of the fpe'ep tubes.

This tank is support-edit; any suitable manner, and the track for the ehain is appropriately constructed toefict the depressionof the travcling plates or sections above the top of the I its intended purpose. I

are similar in construction, except that they tank so as to dip the splints in the impregnating solution, and then raise such plates or sections to withdraw the splints from the solution and permit the progress of the carrier with the impregnated splints.

C. designates the splint-drying structure which is so constructed and organized that the traveling carrier bearing the wet impregnated splints is directed therethrough and the splints are rapidly and thoroughly dried. This structure, in its preferred form, includes a trough into and through which the depending splints are impelled by the carrier. The bottom of this trough is inclined and the carrier is directed in a path parallel thereto, or substantially so; suitable rails a for the support and guidance of the carrier in its travel being provided at the sides of the structure. Y

As herein illustrated the main body of the structure comprises three sections 12, 12, 13, which are bolted together to constitute acasing of suflicient shape and size for The outer sections 12 p are right and left, and each includes an surrounded by, and intimately subjected to outer side wall 14 and a bottom 15 terminating in up-rising end walls 16. The middle section 13 includes a chambered portion 17 and e d extensions 18, and it is interposed between he lateral sections to provide therewith two corresponding side chambers 19 and front and rearward chambers 20, 21, re-..

spectively, the functions of all 'of which will hereinafter appear. middle section, terminates slightly below that of the others, and is; provided-with lateral ledges, which, in conjunction with similar ledges on the inner sides of thesections 12, support two inclined plates 22. These plates constitute the bottom of the trough above referred to. Through this trough flows a stream of granular heat-conducting material 23 into which the splints on the carrier depend during their travel through the trough, such splints thus being the action of, the mobile granular constit uents of the said material. "This material,

in a highly-heated state, is caused to travel 1 by and w th the splints, and thus effect a progressive evaporation of the solvent from .the impregnated splints.

The constituent units of the drying material are preferably pellets, globular in form, or substantially so, so as to be freely movable and thus present only slight resistance to the opposing splints. These pellets may be highly-heated before their delivery to the trough, but I prefer to heat them during their-travel therein while they are in actual contact with the splints, as

thereby a more eflicient drying action is insured. Accordingly I arrange within the casing, directly beneath the bottom of the ture, each of the tubes being furnished at The top of the also provided for the lower burners.

trough, burners 24 for gas or other fuel. In'the present instance there is a series of Bunsen burners beneath each bottom' portion22 of the trough, such burners extending through the side of the structure and being provided with suitable regulating valves 25. The burners are conveniently lighted through tubes 26 provided for that purpose in the respective sides of the strucits outer end with a hinged transparent cap 27 which is normally held in closed position by a suitable spring-latch, as 28. (See Fig.

11). That the flames at the burners may be readily viewed, I prefer to provide in the walls of the structure a series of peep tubes 29. These tubes are arranged in line with the tops of the burners, and their outer ends are covered by transparent material 30, such as isinglass, which is held in place by a ring 31. (See Fig. 10). The flames from the burners 24 impinge di rectly against the undersides of the bottom plates 22, .and the products of combustion pass thence into ducts 32 formed in the inner walls of the respective sections of the casing, .thence to a common chamber 33 at one end of the casing, thence to and through an exhaust pipe 34 leading from said, chamher to a suitable point of'discharge. The

bottom plates are preferably provided on their undersides with ribs 35, extending longitudinally thereof, through which are openings 36 for the free passage of the products of combustion.

The mass of hot pellets tends to roll by gravity to the lower rearward end of the inclinedbottom 22 of the trough, their descent being materially assisted by the traveling splints. Thence they are discharged .upon suitably-disposed lower plates 37 which, being inclined in an opposite direction to the bottom of the trough as illustrated, direct them to the forward end of I the casing. Thereupon the pellets are '110 raised to the upper receiving end of the trough, for a repetition of their travel, as

will hereinafter appear. Withinethe cas ing beneath the lower plates 37, are also provided burners 24 for gas or other fuel, whereby the pellets while passing along such plates are heated and effectually dried; Thd burners are herein illustrated, similarly .to those above described, as of the Bunsen type. They extend through the bottom of they casing, and are likewise provided with the usual regulating valves 25. Primary ignition tubes 26 and peep tubes 29 are The flames from these burners impinge directly against the underside of the plates 37, and the products of combustion therefrom pass thence into. the ducts 32 and are finally discharged through the pipe 34 as above described with respect to the upper burners,

a ovopee The-pliites 37 are preferably ribbed on their undersides Similarly to the upper plates conmeshing-gear wheels "39" on their respective shafts; the desired quantity and depth of the mass of'pellets within thetrough being o governed *by the 'speedof the magnets.

Referring to Figs. :2, 3 and 7, 40 indicates the cores of the magnets and 41 the coils thereof. Thefwires for the coils pass through the centrally bored ends of the shafts 39 respectively, and are connected to contact rings 42'" which are mounted on, and

insulated from,' said-shafts. Electrical contact with these rings is effected by brushes 43 to which are connected the wires 44 leadw ing from a suitable-sourceof-electric energy.

The lower magnet in its rotation progres' sively attracts the pellets at the proximate end o'f the plates 37 and carries them to the space between the magnets. A suitablydisposed scraper 45 bearing upon the surface of the lower magnet strips the pellets therefrom-and deflects them toward the upper-magnet, which latter in its rotation attracts the pellets and-carries them toward the bottom of the trough. A scraper 46 strips the pellets from the upper magnet and deflects :them upon the bottom of.'the trough. Thus a'eOntinuous circulation, so to say,of the mass-of pellets within'the casirlgis'efi'ected; the heated pellets while passing through the trough being maintained at a'subst-antially uniform depth and accomplishing the drying of {the splints rapidly and thoroughly, and-said pellets-while moving along the lower incline being subjected, in turn, to the drying action of the heat from the underlying'burners.

In order-that the vapor or steamevolved from the solvent in the splints during the drying operation-shall be readily removed,

the following construction is-employed; reference being had to Figs. 1, 3, 4 and5; 47 is an elongated cap or channeled member, which is arranged upon the middle'section 13 of :the structure so as to bridge-from end to end the chamber 17, of the latter and in effect medially partition the trough 'for'the splints and pellets. The sides of this channeled member are provided with numerous perforations 48 which afl'ord vents for air suitable point of discharge,.and thus the-va-' ,two spaced plates 52 which inclose the sides,

which-is supplied to the chamber 17 by means of a pipe 49 opening-into the bottom of thelatter. The air upon its entrance to the chamber is heated by contact with the walls of the latter, which air, escaping through the vents 48, is effectually diffused throughout the trough and across thev path of the splints within the latter. This heated air, is directed to a pipe '50 leading r01 .a

or or steam evolved from the solventin the impregnated splints is carried ofi. In the present instance the escape pipe 50 leads from a chamber 51, formed by and between ends and bottom of thestructure, a suitable space for a jacket of insulating material 53 tio'ns55of the structure, but communicatlon between such ends of the chamber and the adjacent portions of the interior of the structure are afiorded bysuitably-disposed passages 56. v In the drawings the-course of the air current throughout the structure is indicated by plain arrows. This current in its passage -not onlycarries off-the vapor or steam evolved from-the solvent in the impregnated splints, but it also contributes to the dry-. ing operation. Furthermore it removes anyslivers or broken splints which are lodged in the cllets-or which-maybe rubbed from 5 the-splmts'by their contact with the pellets. I In this connection it is to be noted that as a. means to spread and shake up the mass of pellets as they leave the trough, and thus facilitate the removal of the contained shvno ers or broken splints by the an current, I arrange within the rearward spaces 21 of the structure, just below the d schargeend of the trough, transverse bars 57, which 1n- Q tercept the descending materlal. A down- 5 wardly extending ledge 58 secured to this end of the structure, serves to direct the current from the spaces 21 to the adjacent dis-' charge passage 56- and thusaid the escape of the splints and slivers.

It is to be understood that I do not confine myself to the particular form or details of construction herein shown and described, .as the same'm'ay'be variously modified withstructure comprising means for supplying 13c heated granular material to the path of the splints during their travel,
