SPECIFICATION forming part of Letters Patent No. 517,625, dated April 3,1894.

Application fi January 5, 1 8 94;.

To all whomit may concern: 7 Be'it known that I, JAMES POWERS, a sub- ,ject of the O zarof Russia, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Machines for Cutting Toothpicks, of which the following is a specification.

This invention has reference to an improved machine for cutting tooth-picks and other articles from veneers the cross-section of which corresponds to the shape of the articles to be; produced; and the invention consists of a machine for cutting toothpicks, &c., which come prises, first, means for intermittently feeding the veneer; second, a stationary plate provided with parallel grooves, over which the veneer passes; third, a plate in front of the same provided with parallel slots in linewith the grooves of the stationary plate; fourth, a series of gang or rotary disk-shaped cuttingknives which are mounted on a vertical shaft and guided in the slots of the guide-plate; fifth, means for moving the gang of cuttingknives over the veneer and back, and sixth, an endless belt or conveyor below the gang of cutting-knives on which the tooth-picks, as they are cut from the veneer, are dropped and conducted to a suitable receptacle.

The invention consists further of certain details of construction and combination'of parts,whic h will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1, represents a front-elevation of my improved machine'for cutting toothpicks from Veneers, some of the parts being cut away and others in section. Fig. 2, is a side-elevation of my. improved machine. Fig. 3, is a detail vertical transverse section of the upper part of the machine, taken on line 3*3 Fig. 1, and Fig. 4, is a detail horizontal section on line 44:, Fig. 3. v

Similar letters of reference indicate corresponding parts in all the drawings.

Referring to the drawings, A represents the "supporting-frame of my-improved machine for'cuttin'g toothpicks from veneers.

The frame A is composed of two-upright standards a a, which are connected by transverse tie-rods a. At their upper ends,parts ofthe frame A are arranged the intermittently-actuated feed-rollers B B by which the veneer,

Serial Nb. 495,837. (No model.)

that is wound up in a suitable roll, is fed to the cutting mechanism. The feed-roller B is supported by suitable journal-bearings on the uprights a a, the feed-roller B being of larger 'size than the roller B and provided with longitudinal grooves or ribs. Continuous rotary motion is imparted'to the shaft of thefeed-roller B from a driving-shaft S by a belt and pulley transmission which is arranged at right-angles-to the shaft of the feed-roller Band supported in bearings of separate standards A, or on suitable brackets attached to the main-frame A, or on any other suitable support. The .shaft of the smaller feed-roller B is guided in slots of the supporting-frame Aand connected at one end with a fulcrumed lever B the upper end of which is pivoted to the shaft of the feedroller B, while the lower end is engaged twice at each revolution of the shaftS by a diametrical cam-piece B the beveled ends of which engage the lower tapering or reduced end of the fulcrumed lever B and produce the oscillation of the same, so as to bring the small feed-roller B at each rotation of the shaft S twice in contact with the grooved feed-roller B so that by thepressure of the rollers B B, the sheet of veneer is taken hold or and fed in downward direction between the feed-rollers. As soon as the diametrical cam-piece B has released the lower end of the fulcrumed lever, the feed-roller B is moved away from the grooved feed-roller B by'means of a, spiral spring I) which is attached by one end to said lever below its fulcrum, and; by its other end to thesupporting' frame A, as shown in Fig. 2. By the receding motion of the feed-roller B the sheet of veneer is released while at each forward motion'of the feed-roller, B, the sheet of veneer is moved forward by the feed-rollers.

Belowthe grooved feed-roller B and tangentially or nearly so, to the circumference 5 of the same, is arranged a plate 0 that is provided with-flanges C at its ends by which it is attached to the standards a a of the supporting-frame A. The guide-plate 0 extends from one standard a to the other and is profront of the guide-plate C. The disk-shaped cutting knives D are splined rigidly to a vertical spindle D, said knives being separated from each other by suitable collars d, and firmly retained on the spindle by means of screw-nuts d appliedto the threaded ends of the same. The upper and lower ends of the spindleD are supported in sleeve-shaped bearin gs D which are provided with threaded shanks d that are arranged at right-angles and which are passed through a vertical crosspiece E and secured to the same by means of screw-nuts d one on each side of the said cross-piece, as shown in detail in Fig. 3.

In front of the guide-plate O is supported on short posts g, arranged at the corners of said guide-plate, a second plate G, which is provided with. parallel slots g, the upper edges of which are in line with the upper edges of the parallel grooves of the guideplate 0, said slots serving for guiding and steadying the rotary cuttingknives D and steadying the same While they pass over the sheet of veneerand exert a cutting action on the same. The slotted plate G is close to the retaining collars d d for the cutting knives, as shown in Figs. 3 and 4. By the guide-slots of the plate G the cutting-knivesD are guided. and steadied during the cutting action on the veneer, so that a uniform width and size of the toothpicks are secured.

The entire gang of cutting knives D is adjustable relatively to the grooved plate and slotted guide-plate by means of the threaded shanks ti ht the sleeves D and the screwnuts 01 so that the accurate position of the knives toward the veneer to be cut is obtained. In caseone of the knives is broken and has to be replaced, or in casethe knives have to be sharpened, the entire gang is removed with the spindle D, by first detaching the sleeves D and then unscrewing the fastening screw-nuts d and removing the intermediate collars d. After the knives are sharpened, they are replaced on the spindle, and secured in position by the collars and screwnuts. The ends of the spindle D are then replaced into the sleeves Diand the same secured again to the supporting cross-piece E. A by. sharpening, the knives become smaller indiameter, they have to be adjusted closer to the grooved plate 0, the slotted guide-plate G being in this case likewise placed closer to theplate O by shortening the sleeves of the supportingeposts g of the guide-plate G.

The cross-piece E, on which the gang of cutting-knives is supported, is guided on the horizontal top and bottom-tie rods a which are made of rectangular cross-section andattached to forward-extending brackets a of the supportingframe A, said rods passing through corresponding recesses in the upper and. lower ends of the cross-piece E. The cross-pieceE is reciprocated by a pitman-connection f with a crank-disk f on the drivingshaft. S, said pitman being connected with wrist-pins f on the crank-disk and crosspiece, as shown in Fig. 1. By this transmitting mechanism, each full rotation of the driving shaft S imparts a forward and backwardly reciprocating motion to the crosspiece E and the gang of cutting-knives supported by the same, so that the sheet of veneer which is fed over the grooved guideplate 0 is cut by the forward and backward motions of the knives into as many toothpicks as there are cutting-knives arranged in the gang. During the forward motion of the cross-piece, the cutting-knives are rotated with their spindle so as to exert a uniform cutting action on the sheet of veneer which is at the time in front of the guide-plate 0. During the backward motion of the gang of knives, the sheet of veneer is likewise held in stationary position so as to be subjected to the cutting action of the knives, so that during both the forward and backward motions of the cutting-knives a set of tooth-picks is out. When the gang of cutting-knives arrives at the end of theforward or backward stroke of the pitman f, the feed-rollers are rapidly rotated by the action of the transmitting belt and pulley mechanism and by the motion of the smaller feed-roller and oscillating lever B so that; the required length of veneer is fed forwardover the guide-plate O.

The batch of toothpicks which is cut by the forward or backward motion of the cutting knives is dropped from the same onto a horizontal apron or conveyer F,simply by the retary motion of the knives and the action of the guide-plate G, which acts as aclearingplate for the picks. The apron F is mounted on suitable rollers, to which continuous rotary motion is imparted by abelt and pulley transmission from the shaft S, as shown in Figs. 1 and 2. From. the apron or conductor the toothpicks are conveyedto a suitable re ceptacle for bundling and packing.

It is obvious that. in place of toothpicks, any other articles, such as match-sticks, cigar-lighters, 800., can be made and thatwhen the machine is built on a somewhat larger size, heavier veneers or sheets canbe cutinto strips or pieces useful for. kindling wood and the like. i

The advantages of my. improved machine for cutting toothpicks are, first, that a very large quantity of toothpicks can be made within a given time, as witheach rotation of the driving-shaft a number of toothpickscorresponding to twice the numberof cuttingknives arranged in the gang are cut from the sheet of veneer; second, that the machine is of a comparatively simple construction and can be furnished at small-expense, being 01)- erated either by hand or power, astdesired; thirdly, that owing to the automatic Working of the machine, one man can attend to several machines so as to keep the same supplied with the required quantity of veneer.
