SPLINT-CUTTING MACHlNE.

SPECIFICATION forming part. of Letters Patent No. 311,496, dated February 3, 1885.

Application filed June 1!], 184. (No mode.)

To all whom it may concern.-

Be it known that l, JOHN D. JONES, a citi- Topeka, in the county of Shawnee and State of Kansas, haveinvented certain new and use 'fullmprovements in Splint-Cutting Machines and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to machines for cutting splints for matches or other uses; and it con sists in the novel construction, combination, and arrangement of the several parts, as will be hereinafter more fully described and claimed.

In the drawings, Figure 1 is a perspective view of my machine. Fig. 2 is a vertical longitudinal section thereof. Fig. 3 is a detail View of the feed mechanism.

The supporting or main frame is composed of two upright side plates, A A, formedpreferably,with flanged feet, as shown, to facilitate the fastening thereof to the bench or stand.

tween the upper ends ofthe plates, and is provided on one end with the power-pulleys B, and on the other with a balance or fly wheel, I). The eccentric b is formed on the middle of the shaft between the plates A A. The plates A A are provided near their frontedges with suitable guides for the cross-head O,which supports the cutting-knife c, and has the connecting rod or pitman b pivotally secured to its upper end, and said pitrnau is screwthreaded at its opposite end into the eccentricring, so the length of the stroke may be adjusted as desired. The cross-head O in operation reciprocates verticallyin the guides of the framing, as will be understood. An arm, 0 is fixed to the outer side of the cross-head, and projects laterally beyond the frame-plate A, for the purposes presently described. Rollers R R are journaled in the lower edge of the main frame, between the plates thereof, and two corrugated feed-rollers, D D, are journaled one above the other near the outer end of the said frame, the lower roller, D, being in line with the anti-friction rollers R. The opposite ends of these rollers D D are journaled in yielding bearings I), (see Fig. 3,) cushioned by rubber or other suitable elastic substance, so as to provide for slight variations in the thickness of the material in to be cut, the rollers D 1) running on, respectively, the upper and lower sides of such material, as will be understood from Fig. 1. The journals of the rollers D D are extended beyond the side plate, A, and have secured thereon gears 11 d, meshed together, so said rollers will be con currently actuated and revolved in opposite directions, in order to effect the forward feeding of the material toward the cutter, in the manner presently more fully set forth. The extended journal of the roller D is also provided with a ratchet wheel or ring, at, which is engaged by the pallet, presently described, for the purpose of actuating the feed-rollers D D. A bar, E, is pivoted at its inner end to the side plate, A, and extends thence forward, and has its opposite end carried in advance of thesaid plate,in position to he engaged on its under side, and raised vertically by the arm 0, extended laterally from the cross-head, as before described. The arm E is formed with a horizontally-elongated slot, 6, about midway its length, and is held at its outer end in a suitable guide, E. The basebar E of guideframe E has a set-screw, E turned vertically upward through it, and may be adjusted above the bar to any proper degree, in order to vary the distance to which the arm E can fall, and thus regulate the feed of the machine, as will be understood from Fig. 3. The outer end of the arm E is given a downward tension, preferably by means of a spring, 0, as shown. This spring causes the downward movement of the arm when released by the downward stroke of the cross-head. It will be understood that a weight could be used instead of spring 6; or the outer end of arm E could be so connected with arm 0' of the crosshead that the latter will give the arm E a positive downward as well as upward movement; but Iprefer to employ the construction shown,and before described. A pallet, F, has its upper end secured to arm E, preferably by means of a bolt passed through the slot 0, so the point of connection may be adjusted along arm E to vary the length of the stroke of the pallet. The lower end of this pallet is formed with a clutehj, adapted to engage the ratchet-wheel d and revolvethe same on the upstroke ofthepallet. A stop-pawl, f ,is also pivoted to the pallet and engages with the ratchet d",to hold the feed-rollers, and thereby the stock or series of ribbons, in position during the operation of cutting. It is manifest the location of this stop-pawl might be changed from the pallet to the frame-plate, or said pawl might be dispensed With,though I prefer to use it, as shown and described. A spring, F, connects the pallet with the plate A, so as to hold the clutchf in engagement with the ratchet-ring (1 as will be understood from the references.

In the manufacture of my machine I construct the ratchet-ring and feed-rollers so the number of teeth in the former hear such a relation to the diameter of the feed-rollers D D that one tooth ot' the ratchet is equal the width ofthe splint to be cut, measured on the circumference of the feed-rollers.

The material to be split into splints has first been cut into ribbons by the usual form of veneer-cutting, the grain of the wood running parallel the width of the ribbons, and this width representing the length of the splints desired, as will be understood. Anumber of these ribbons are placed in the frame on the rollers R R, and have their forward ends brought between and held firmly by the feeddrive-pulley and the shaft made to revolve,

operating the eccentric, and causing the crosshead to reciprocate in its guides, cutting the splints with each downstroke, and by means of the lateral arm thereof actuating the arm E and pallet F, engaged with the ratchet (V, and thus by the before-described mechanism the blanks are fed forward in position for a new cut of splints, as will be appreciated.

By adjusting the connection of the pallet and its operating-arm the length of stroke of the pallet an d'the extent of revolution of the ratchet may be varied so as to increase or diminish the width of the splints, as desired.

In Fig. 1 it will be seen the cross-head is shown at about its highest point and the bar Ehas been elevated by part 0". Vhen the crosshead is forced downward,the bar E falls, bringing the pointfin position to again engage the teeth of ratchet d. In operation the bar E is always in contact with the part 0*, and rests on said part, being raised thereby,and lowered when said part c is lowered, as will be understood from the drawings and foregoing description.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination of the cross head, the feed rollers both having intermeshed gears, and one of said rollers being provided with a ratchet-wheel, a pallet adapted at one end to engage the ratchet-wheel, and having its opposite end supported onthe pivoted arm, and the arm pivoted at one end, and having its other end operated by the cross-head, sub stantially as and for the purposes specified.

2. The combination of the feed-rollers having theirjonrnals or shafts provided with intel-meshed gears, the ratchet-ring secured on. one of said journals, the arm pivoted at one end and extended approximately horizontally along the framing, the cross-head provided within a bar or extension engaged with the said arm, and a pallet depending from said arm and having a clutch adapted to engage and operate the ratchet-ring, all substantially as and for the purposes set forth.

3. The combination of the cross-head provided with lateral arm or extension 0*, the feed-rollers having their journals extended, and provided with intermeshed gears, the ratchet-ring secured on one of said journals, the arm E, pivoted at its inner end, and having its opposite end extended in position to be engaged by the bar a", the pendent pallet secured at its upper end to the pivoted arm, and having its opposite end adapted to engage the ratchet-ring,and the springs 6 F,se-

cured at one end to the framing a, and at their base-bar of said frame, substantially as and for the purposes set forth. In testimony whereof I affix my signature i presence of two witnesses.

JOHN D. JONES.
