MACHINERY FOR CUTTING WOOD FOR MATCHES, SPLINTS, AND MATCH-BOXES.

SPECIFXCATION forming part of Letters Patent No. 398,593, dated February 26, 1889. Application filed May 1, 1888i Serial No. 272,509. (No model.)

To all whom it 722.0 concern:

Be it known that I, NVILLIAM ELLIS, a subject of the Queen of Great Britain, residing at Peckham, countv of Surrey, England, have invented certain new ano useful improvements 1 in Machinery for Cuttin \Yood for Hatches, Splints, andMatclrlloxcs, o. which the follow ing is a specification. This invention relates to iilitlllllti) for cutting wood for matches, splints, and matchi boxes from a large log revolved, as in a lathe, against a long knife, which takes off a shavin g the whole length of the log, the knife regularly following up the log while cutting, so as to cut up a whole log. Arranged before the knife is a rotarylongitudinal incisor, which makes longitudinal incisions in the log the width and depth of a match, and circular cutters, which make circumferential incisions in the log the length of a match or splint or match-box wood apart, so that the shaving when out off by the long knife is in matchwood or splints or box-wood, according as the incisors have been set. These results are obtained by the mechanism illustrated in the accompanying drawings, with aid of which I Will proceed to full describe my invention, the various parts in all the views being denoted by the same letter of reference.

Figure 1 represents in front elevation the left-hand part of a machine constructed aci cording to this invention; Fig. 2. a similar view of the right-hand part; Fig. 3, a vertical 1 transverse section at line 1 2, Fig. 2; Fig. at, a 1eft-hand transverse sectional view taken at line 3 4, Fig. 1, with the addition thereto of a 3 means forholdingacrossshaft. Figcshowsin front sectional elevation a detail view, drawn to a larger scale than the previous figures embodied in Figs. 1, 2, and of the means employed inside machine at each end for upwardly advancing the shaft: carrying the cir- I cular knives for ci rcuinferentially incisin g th e revolving log; Fig. ti,a sectional plan view at line 7, Fig. 5; Fig. 7, an enlarged sectional side elevation of upper portion of frame with sliding block carrying the device for longitudinally incising the surface of the log, shown fully in Fig. and embodied in Figs. 1 and 2;

sectional view, embodied in Fig. 1,01? the arrangement 0t gearing for transmitting motion for advancing the long knife, the longitudinal incisor, and the circum lerent ial incisor toward the log, and for allowing a cross worm-shaft to be lift (d to allow dilt'erent-sizcd worm-wheels to engage worm to alter the speed of the ad- 1 vanee of the long knife to enable different;

thicknesses of shaving to he cut off the log. Fig. 10 is a detached enlarged longitudinal sectional view, embodied in Fig. l of the series of diit'erent-sized worm-wheels mounted on a sleeve arranged to slide on shaft to engage the worm to change. the speed of the advance of the knives. Fig. 11 is a side view, and Fig. 12 a front view, of the sectoral bearing and bracket for holding the end of the cross wm-m-shat't.

The bearing in these two figures is shown provided with a screw device for obtaining the requisite accurate adjustment of the worm to different sized worm-wheels and a clampingscrew for securing such adjustment. Fig. 13 is an enlarged side elevation of a portion of a curved guide at each side of the machine, shown fully in Fig. 3, in which the sliding blocks that hold the long knife-carrier travel; and Fig. 1i is a section of same through line 10 These two views show an ad j ust able wear-shield for the upper bearing of the guide. Fig. 15 is a detail partial end elevation at lines 5 and (3, either at Fig. 1 01' E2, of the outside of one of the long knife-carrier sliding blocks embodied in Figs. 1, 2, and 3,

showing compensating means to enable the slidingblock to be moved along a curved guide by a held straight screw. Fig. 1G is a front view of Fig. 15, with the addition of a partial view of the long knife-carrier, the means for se curing the same to the sliding blocks, and

of compensating means embodied in Figs. 1, 2, and 3, and on a larger scale in Fig. 15.

Ais the main frame and bed of machine; 13, the log of wood held on chucks 13, carried in one end of short chuck-shafts B 13 suitably held in bearings in the frame and revolved by large gear-wheels turned by pinions B on the main driving-shaft 15". The log-chucks B are driven into the log by the screw ar steadying-roller for the knife while cutting. 17 and 18 are respectively front and sec-- tional elevations of detached enlarged views face of the log the depth of a match.

rangement l3, operated by gear-wheels B turned by pinions B on short shaft B, revolved by pulleys B an d B, pulley B being for driving the chucks B into the log B at each end of it and pulley B for withdrawing the chucks. 'To enable these actionsto be done, the shafts B B are free to slide the requisite distance for chucking the log. To allow this sliding action without throwing the machine out of working gear, the pinions 13 are made wide, as shown. To enable the chucks B to be withdrawn by hand, the end of the shaft B is connected to a screw, to which is fitted a hand-wheel, B to turn screw.

C is the long knife extending the length of the log, secured to the front of a knife-carrier, C, by front screws, 0 and further secured at the bot-tom by claws (see Fig. 8,) arranged at intervals along the bottom of carrier 0. The height of the knife is first adjusted by screws C" and then secured against the face of the carrier 0 by the screws C The knife-carrier C is held by trunnions C in sliding blocks l). The trunnions C admit of the carrier C being turned to adjust the edge of the knife 0 to the leg, when it is secured by the screws 0 passing through the curved slots C The sliding blocks D travel in a curved guide, D. Consequently the edge of the knife 0 is compelled to take the radial direction of the curve, by which means the edge of the knife will be automatically adjusted and held in the necessary position throughout for cutting up a log from its largest diameter to the smallest it is possible to cut it. The sliding blocks D are moved by a straight screw, D held in suitable bearings and turned by worm gearwheels D'. To enable a held straight screw to move a sliding block in a curved guide, the following compensating means are employed: On the side of each of the blocks is. p tted a slide, D having a pivoted bl $1,12 through which the straight screw D as e and engages, thepivot D of blocks being held in sliding pieces D by a groove, D and set-screw D E is the incisor for longitudinally incising the surface of the log B. This is composedof apolygonally shaped roller, E (shown in detail at Figs. 7 and 8,) with dovetail slots to hold sections of steel, E with the incising teeth or knives planed out of the solid. This incisor is carried in sliding bearings F, moving in a guide, F, preferably of acurve correspoi'i' ding to the curve of guide D, so as to travel at exactly the same speed asthe knife C. If, however, the guide F ismade straight, the bearings F must be arranged to move a trifle slower than the knife 0, to compensate for the extra distance given by the curve. The bearin gsF are presseddown by the screws F operated by worm gear-wheels F through which the screwspass and engage. These wheels are held in thetop of main frame A. The screws F press the knives into the sur- If the guides F are made curved, as shown in the drawings, compensating means will be necessary for the screws F Such means are shown in the drawings, similar in principle to what has already been described for screws D but slightly different in detail, as follows:

The top of bearings F is formed with a dovetail groove, in which is a slide, F, to which is hingedthe bottom end of the screw F Under the log B is arranged the circumferential incisor. This consists of a loose running shaft, G, carried "in suitable bearings, G, arranged to slide vertically in the inside of the frame of the machine at each end, the bearings G being pressed upward. by screws G revolved by worm gear-wheels i This shaft G is finely screw-threaded along its length, and carries a number of circular knives,

l, held between nuts G screwed 011 the shaft and set the length of a match or splint or boxwood apart. These knives are pressed into the log by the screws G and so circumferentially incise the log as it revolves, so that the shaving, when out off by the long knife C, is in match wood or splints 'or box-wood.

hen using this machine for cutting wood for match-boxes, the longitudinal incisingknives must be the width apart of the length of the match-box and the circumferentialincisors set the width apart of the length of the wood to be bent round to form the box. By this arrangement the grain of the wood will run the length of the wood, and soadmit of the wood bein bent round without breaking th rough.

The necessary movements in unison of the knife C, the longitudinal incisor E, and the circumferential incising-knives G toward the log B are effected from the shaft-B as follows: On an elongationlof one of the bearings of the shaft B (best seen at Fig. 9,) and free to revolve thereon by abeari-ng-ring, H, and onthe shaft' by another beari-i'igq'ing, H, is a bracket-bearing, H carrying one end of a cross shaft H One end of this shafthaslgeyed to it a beveL-Wheel, H gearing with another bevel-wheel, H5. The latter is loose on shaft 13*, but prevented from turning, by a feather, K, let into a groove, K, (see Fig.- 9,) to allow theshaft B to be moved for chucking the log. Near the other end of shaft H is a worm, H which gearswith change-wheels H These wheels are carried ona sleeve, H arranged to slide on shaft I, and held where desired by set-screw H The outer end of shaftis held in a sectoral bearing, H slidingv in a corresponding guide in pedestalframe H, the bearing H being lift-ed or lowered by a screw, H and secured by clamping-screw H This arrangement enables the wori'n H to be set to engage wheels of different diam eter to impart different speeds to the shaft I without change of speed of shaft 13. On shaft 1 are keyed two worms, 1 I gearing with worm-wheels D and a bevel wheel, 1 which imparts motion to bevel-wheels I and I the former keing keyed onto a shaft, I", which has a bevel-wheel, I at the end, gearing with bevel-wheel I keyed on a horizontal shaft, 1, having worms I which operate the wormwheels F The bevel-wheel I is keyed onto a short shaft, I, at the end of which is another bevel-wheel, I gearing with another bevehwh eel, I keyed onto one end of a shaft, I, which has on the other end abevel-wheel, I gearing with bevel-wheel I keyed on shaft J. This shaft has worms J, which engage the woriirwhecls l to operate the vertical screws G P this arrangement, at whatever speed the shaft I may be driven, the knife C, the longitudinal incisor E, and the circumfer ential incising-knives l" all approach the log in unison.

To provide for the wear at the top of the curved guides D, the upper part is fitted with a steel shield, L, for the top of sliding blocks D to bear against. screws M, which enable the shield to be raised or lowered, as required.

N 's a lon roller to bear against log ll, to assist in steadying' the edge of the knife while T cutting.

The machine is driven by the pulley O on short. shaft I having-kc ed on it a )IlllOl'l C gearing with large gear-wheel R on main driv- I ing-shaft B.

Having now fully described my invention,

This shield L is held by E I declare that what I consider novel, and desire to secure by Letters Patent of the United States, is
