HOLLON o. SPAULDING, OF EXETER, NEW HAMPSHIRE, ASSIGNOR on ONE- HALF TO FRANK W. HALE, OF BOSTON, MASSACHUSETTS.

MATCH-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 536,402, dated March 26, 1895.

Application filed August 15, 1892.

To all whom it may concern.-

Be it known that I, HOLLON O. SPAULDING, a citizen of the United States, residing at Exeter, in the county of Rockingham, and State of New Hampshire, have invented certain new and useful Improvements in Match-Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The invention forming the subject of my present application for United States Letters Patent relates to certain improvements'in the art of manufacturing matches and in the mechanism therefor.

My invention pertains more especially to that class in which the match-splints or sticks are made from a continuous veneer or ribbon having a Width equal to the length of two matches. I

By means of my improvement the veneer while passing through the match-making machine is divided longitudinally, being transversely of the grain or fibers, each part being next separated into splints which are automatically fed singly to an endless carrier or conveyor. The splints are then subjected to the dipping and drying operations, while still mounted in the conveyor, after which they are automatically released therefrom and suit ably packed.

The object I have in view is to produce a superior match at a minimum costfor labor or attendance and materials.

To that end my invention consists essentially in the combination of corrugated rolls arranged to form and detach splints transversely from a continuous strip or veneer; means for dividing the veneer longitudinally; a continuous flexible conveyer for holding and carrying the splints during the processes of dipping and drying, and mechanisms for automatically inserting or feeding the splints endwise into said conveyor and discharging them therefrom, all as will be more fully hereinafter set forth and claimed.

In the accompanying four sheets of draw- Serial No. 443, 09s. (No model.)

2 is a plan view. Fig. 3,'Sheet 2, is a side elevation, in enlarged scale, of the head portion of the machine. Fig.4 is'a plan view of the same. Fig. 5, Sheet 3, is a sideelevation, viewed from the opposite side of the machine,

as compared with Fig. 3. Fig. 6 is an enlarged longitudinal sectional view, taken on line y y of Fig. 4. Fig. 7, Sheet 4, is a perspective View, showing the action of the Separator or feed-wheel upon the traveling splints. Fig. 8 is a plan view of a piece of the veneer detached, showing the action of forming-rolls and saw. Fig. 9 is a longitudinal sectional view, taken on line 0 0 of Fig.8. Fig. 10 is asec- 7c tioual view, taken on line a: m of Figs. 6 and 7. Fig. 11 is an enlarged transverse sectional view of the carrier, mounted on the initial carrier pulley. Fig. 12 is a similar view, showing the carrier mounted on the guide pulley. Fig. 13 is the same, except that the gripping edges of the carrier are slightly modified, and Fig.

14 represents a finished match, as produced on my improved machine.

The drivingmechanism is mounted in the head portion B of the machine. See Figs. 3,

4 and 5. As drawn a traveling main belt drotates the Shaft d, which in turn through the medium of a belt (1 drives the lower forming roll shaft d Secured to this last named shaft is a gear e meshing into an intermediate gear e, the latter working in a similar gear e which drives the upper forming roll 17 through the gear 6 These same intermediate gears e, e also intergear with gearse, e secured respectively to the lower and upper shafts carrying the forward forming rolls ff. By this arrangement of gear ing the rolls 1) and f are simultaneously revolved in the proper direction to feed the veneer a at a uniform rate of speed, the said gears e, 6 e and 6 being alike.

As drawn the driving mechanism just described is employed to operate the endless flexible'conveyers A, A, arranged to receive no the splints as fast as formed and also carry them while mounted therein through the dipping and drying devices. To each end of the upper roll shaft d (Figs. 3 and 4:) is secured a bevel gear g, which meshes into a smaller gear secured to a short horizontally mounted shaft g and these in turn through the medium of a pair of bevel gears g revolve the two vertical shafts g These shaftsaresuitably mounted in the frame work of the machine and carry each an initial conveyerwheel or pulley 0 whereby the latter revolves in a horizontal plane; the relation of wheels '0 to the said forward forming-rolls f being clearly represented in Figs. 3 and 4. The

faces 0 of these wheels 0 are made slightly V-shape or beveled, see Fig. 11, thereby causing the traveling conveyors, which are divided longitudinally as hereinafter described, to automatically open and receive the adjacent ends of the splints.

The head portion of the machine is provided with a stationary bed or tablet arranged to support the veneer-ribbons, &c., and is located between the upper and lower series of forming rolls. Side guides 13 secured to the table serve to keep the veneer and severed splints m in position until the latter are fed into the separator h to be diverted by it, right and left, into the two conveyers. Extending upwardly through the table is a veneer dividing saw 0. This latter as drawn isdriven by a belt (1 leading from a pulley d secured to the shaft d.

The separator h is secured to a shaft 71 mounted to revolve in bearings located below the table 15. Rotary motion is imparted to the separator by means of a gear-train 7o, operated by the gear 6 shown by dotted lines in Fig. 3.

Although the means or mechanisms represented for driving the several parts which operate upon the veneer and splints have been thus specifically described,yet it is apparent that other equivalent means may be employed without departing from the spirit of the invention.

In further carrying out my invention I employ fibrous stock having the form of asuitably prepared continuous veneer or ribbon at. Practically the stock thus used is some of the lighter kinds of wood, as pine, so cut that the grain or liber lies transversely of the veneer; the width of thelatter being equal to or slightly exceeding the length of two matches. The sticks or splints successively formed and detached from the forward end of the veneer are when finished termed parlor matches, as distinguished from bunched or carded matches. The veneer may be first moistened or steamed and wound intoaroltand mounted at one end of the machine, as indicated in Fig. 1. The free end of the veneer is introduced between a pair of driven combined feeding and forming rolls 1), having their faces provided longitudinally with aseries of grooves or corrugations b; the same extend ing around the circumference of the rolls. The rolls are alike in size and are so adjusted sea 10a that the grooves in one are opposed by those of the other roll; the space thus formed being the counterpart of the match-splint transversely. The grooves are separated each by a sharpened longitudinal rib b which forms a cutting edge. It will be seen that as drawn the veneer in width is equal to the length of two matches; and is divided longitudinally into two ribbons e e by a continuously revolving saw 0 after the said rolls have completed their work upon the veneer. In order to prevent a complete separation of the splints before the veneer is divided I provide portions of the surface of the rolls 1) with ribs I) having less height than the ribs 19 or if desired the grooves may be omitted entirely. See Fig. .4. These substantially plain portions leave an ungrooved surfaced (Fig. 8) upon each side of the veneer,corresponding to the center portion of the splint longitudinally and as clearly shown along the two ribbons e. The several rolls, especially the main rolls 1), are kept hot if necessary, thereby evaporating the moisturefrom the veneer and rendering the splints more easily acted upon by the subsequent processes. The rolls may be hollow to receive steam or they may be heated by burning gasjets. As drawn the journals or axes of the rolls are hollow and connected with a suitable steam supply 5-, Fig. 4. The splints are completed and separated from the said ribbons by means of the two pairs of narrow corrugated rolls f. These rolls are also positively driven and have a surface speed equal to that of the main rolls b. The rollsf act upon the ungroovedsurfaces of the ribbons thereby shaping said portions to correspond with and forma continuation of the grooved part produced by the main rolls. I prefer to separate the two series of formingrolls b,f, in order to locate the splitting or dividing saw a between them, as indicated in Figs. 4 and 6.

Up to thispoint it is clearthatthe machine operates to divide the veneer longitudinally and separate each of the two resulting ribbons into suitably shaped match splints m. Now, in order to prepare and tip theigniting end of the splintsit is necessary to employ a conveyer which receives and holds them during the processes last referred to. In order to accomplish this result I have devised a novel mechanism for automatically placing the splints singly from both ribbons at intervals into the continuously traveling conveyers. The means employed consists essentially of a continuously revolving wheel 72,

which I term a separator or feed-wheel, lo-

cated just forward of and between said series of rolls f, as clearly represented in Figs. 4; and 6. The peripheral edges and ends of this wheel are provided each with a series of ratchet or wedge-shaped lugs h h which exftend toward the center or shaft h on which the wheel is secured. The feed-wheelrevolves .in the saw-scarf produced by the saw 0, its rate of movement and relation to the rolls f ICO being such that as each'splint is detached from its neighbor its inner end is smartly struck by the adjacent wedge-face, thereby forcing the splint endwiseinto the carrier A.

By reason of the two series of wedge facesh' the splints as detached from both ribbons are forced into both carriers simultaneously; The speed of the feed-wheel is such that the time occupied in passing from one lug h or ratchet to the next is substantially equal to that of the rolls in feedingthe ribbons, from splint to splint.

The carriers A are so mounted and operated that they travel at a rate of speed slightly in excess of the ribbons so that as the detached splints are fed into them, by the action of the feed-Wheel it, they are automatically spaced a short distance apart, to prevent them from sticking together when the free ends are passed through the dipping pans.

The carriers A may be constructed in various ways, though I deem the one represented in Figs. 11 and 12 to be preferred. In this case it consists of an endless belt at of rub ber, leather, canvas or other suitably flexible substance to which are secured, "longitudi-l nally, upper and lower strips n','or sections, of elastic material, as rubber, in such a way that the inside or adjacent edges 61 are'normally in contact and capable of gripping the splints and supporting them with the necessary riigdity while they are being subjected to the dipping process. I In mounting the carriers I prefer to locate the initial carrier-pulleys 0 so that they will revolve in a horizontal plane, the'axes of rotation being substantially in line with ora little to the rear of the axes of the upper and lower shafts carrying the rolls f and at right angles therewith, as clearly shown in Figs. 3 and 4. The face 0' of the pulleys 0 may be angular or slightly V-shaped, the transverse axis or apex 0 thus formed bein g substantially in line with and contiguous to the longitudinal axes of the passing splints. From this it is obvious that the belt n in its passage around the carrier or guide pulley 0 conforms to the shape of it transversely, thereby causing the adjacent edges of the strips n to separate along the joint m as at n Fig. 11, to freely receive the outer ends of the splints as they are successively fed into it by the action of the feed-wheel h. The carrier-belt is gradually transformed from the V-form to a flat or normal shape immediately after the introduction of a splint,.said transformation being effected by bringing the belt in contact with a small flat-faced guide-pulley 19 mounted just forward of the main guidepulley. See Fig. 4. By means of this arrangement it is obvious that the pulleyp operates to close the carrier-joint uponthe splints immediately after the latter are placed in position therein. Fig. 12 shows a cross-sectional view of this pulleyand the carrier; the latter having a match-splint mounted therein. The meeting or adjacent edges of the carrier strips 17. may be at right angles with the belt,

, thereto.

as in Fig. 12, or the strip may be undercut or beveled, as at n Fig. 18, thus forminga space a next to the belt. surface will be at the outer portion only. When thus constructed the matches are more readily released during the passage of the carrier over the discharge pulley, or even the main carrier pulley-that is to say the action of the latter upon the carrier may serve the double purpose of receiving the splints and discharging them from the carrier after they have passed through the dipping and drying processes.

In machines of this class it is a common practice to mechanically pass the outer, or free ends of the splints through suitably arranged dipping pans for the purpose of tipping them with sulphur, phosphorus or other suitable materials or compositions such as are employed on the heads or igniting ends of friction matches. I make no specific claim in the present application for patent for means for effecting such tipping of the splints. In the drawings, Figs. 1 and 2, forming a part of 'this specification I have, however, shown an arrangement of devices (whereby the splints are tipped with igniting materials and dried before they are discharged from the conveyors. As drawn the two endless conveyers A, A, are conducted to the rear end of the machine where they are mounted on a series of guide pulleys u so arranged that the In this case the gripping 7o conveyors travel back and forth a number of 103 guide-wheels y so constructed and arranged with relation to the wheels 0 that it is gradually turned or deflected from avertical plane to travel in a horizontal plane, thus causing the splints to point downwardly. While traveling in this position the free ends of the splints are passed through the liquid sulphur after which they are subjected to a similar operation which causes the phosphorus 0" contained in the pan of the furnace D to adhere to the sulphurized portion of the splints. The furnaces O, D may be separated from each other to facilitate the drying of the splints or if desired pans containing other suitable igniting substances may be substituted for the ones shown, or they may be used in addition Upon leaving the last pan the splints are kept moving back and forth a number of times over the heated coil E thereby .thoroughly drying them by reason of their contact with the hot air rising from the coil after which they are discharged from the conveyers into receptacles s. The splints now have been converted into matches to (Fig. 14) and provided with the usual igniting tip or end to. The matches maybe taken from the boxes 3 and packed in any well known manner, preparatory to being sold and used.

I do not limit my invention to its combination with dipping and drying devices such as just described, as the splints may be readily subjected to dipping operations arranged in a different manner and order. Neither do I limit myself to the production of any particu lar kind of friction match.
