EXCELSIOR-MACHINE.

SPECIFICATION forming part of Letters Patent No. 499,168, dated June 6, 1,893.

Application tiled July 5| 1892. Serial No. 438,854. (No model.)

To all whomit may concern:

Be it known that l, BART KANE, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Machines for Making Excelsior, of which the following is a specification.

My invention 'relates to improvements in machines for making excelsior. are to provide a machine which may be kept continually in operation at a high speed, produce the least possiblewaste of material, have few parts to get out of order or require attention, does not require skilled labor to operate, and is not dangerous to the attendant.

The invention will be lirst fully described in connection with the accompanying drawings, in which like parts are indicated by similar reference letters wherever they `occur throughout vthe various views,land afterward. its novel features will be particularly referred to andpointed outin the claims. l

Figure l is a side elevation of myimproved machine with one of the feed chutes removed to expose the parts back of it. Fig. 2 is a transverse sectional View of the same taken through line w. of Figfl. Fig. 3 is a similar section through line y. y. showing an inverted plan view of the cutter Wheel and its Fig. 4 is a detail View upon an enlarged scale partly in side elevation and partly in central longitudinal section of the attachments for scoring the face of the block in advance of the cutting blades, the frame holding the scoring blades being in its central position. Fig. 5 is acentral transverse sectional view of the device shown in Fig. 4 upon the same scale.

The frame of the machine within and upon which the operative parts are mounted is preferably formed of the upper and lower cross framed pieces A... A. braced firmly by the uprights A2 and a similar cross frame A3 the ends of which are tenoned to enter vertical grooves in the inner sides of the uprights A2 to which it is secured in its lower position by bolts a. The shaft B which carries the cutter wheel C, has its lower bearing in a step b centrally secured upon the frame A. It

. passes through the frame A.3 and has its up- Its objects per bearing on the frame A. Upon the uptheir edges may be projected above the cutterA Wheel to takethe requisite bite on the blocks l fed down upon them through the chutes E ofwhich there are four. VThese chutes are secured in a vertical position between the arms of the cross-frames, AYAS, and extend as shown to the top of the frame, but it is the intention to carry them up to the door or room above that in which'the machine is operated 'in which the blocks are prepared and fed into the chutes. The chutes thus being always kept full of the blocks the lower ones will beheld against the action of the cutters by the weight of those above them, and the necessity.

of weights, springs, or other inconvenient contrivanc'es, to hold the block While acted upon is dispensed with.

The scoring blades f are clamped in a rectangular open box or frame F, ,between Hat steel bars f which space the scoring blades the proper distance apart to make strands of the required size, by a set screw (shown in dotted line)` which is tapped through the end of the frame.

per extended end of the` shaft is secureda I The frame F, is held between the forked ends of a pivot pin F which pin is pivoted in a hanger G, depending from an open box or frame H. The ends of the frame F, areoverlapped by plates h secured across the ends of the frame H. These plates steady the frame F, as it vibratesupon its pivot in either direction Within the frame H. The sides ofthe frame H are beveled to fit within a radial slot in the edgeof the cutter wheel. The walls of the slot A are inclined counter to the edges of the box kH, which is adapted to slide within the slot in the cutter wheel and is confined in place by plates h',

IOO

secured to the under side of the wheel to overlap the edges of the sliding boX; The box is held within the slot by clips h2 which are secured in the edge of the cutter wheel and overlap the edges of the radial slot. The box H is normally held against these clips andin its outer position by coiled springs h3, which are seated in holes in the inner Wall of the slot, and press against the inner end of the box H.

The frame F, is normally held at an angle to the radii of the cutter by 'coiled pulling springs f2, which are connected to its opposite ends and to studs secured in the under face of the wheel C, for the purpose of presenting the scoring knives in the proper po sition to the end of the block, and gradually i introducing the guide pinsf, which depend" from each end of the frame F, between the guide plates I, which compel the frame F, to travel parallel to the sides of the feed boxes while acting upon the blocks fed to the cutters. shaped angle bars set upon angl-e feet i', which are secured upon the crossframe A. The horizontal Webs of the guides I are slotted to passthe Shanks of bolts fi', which are tapped into thefeet. By this means the guide plates are made adjustable toa compensate for Wear,and for convenience in` properly adjusting parts when the machine is set up. There are of course guides opposite: the dischargeof each chute but only one set' is shown.

To the underside ofthe cross arms of'frame A3, are secured ribs a which project down below?` the lower edge of the feed chute, and are arranged at'` a tangent to theV path of travel` of the knives c, for the purpose of discharging the slabs or slizvers left from the top of the blocksabove the wheel. So soon asa block is so nearly used up that its top comes below the edge of the feedfchute,.one of the cutting knives striking itwill drive it from under the chute and the rib will guide its course to the outside of the machine.

The machine when set up for use is` mounted upon standards or anv open frame Work some distance above the ioor and the bottom part The guides I are preferably madey of L` from near the upper face of the cutter wheel to base incased bya sheet metal coverso that the excelsior is discharged below in a convenient position to be removed while the slabs or slivers are discharged by centrifugal force at t some distance fromthe finished stock.

It will be obvious to those skilled in the art after an examination of my improved machine that many mechanical changes and sub- 1 stitutions may be made in some of the parts without varying theprinciple or mode of operation of the machine and I would hence y have it understood that I should consider such mere mechanical deviations as within the spirit and scope of my invention.

1. The combination substantially as speci fied in an excelsior machine of the cutter wheel C, radially slotted to receive the frame carryin g the scoring blad-es, and the cutting knives 10, secured in said Wheel, the vertically arranged feed boxes, the radially sliding frame H, carrying the frame holding the scoring blades, the hanger G, depending from the `frame H,theframe F, pi-votcd in said hanger, the scoring blades carried in frame: 1F, the springs to hold. the scoring blades normally at right angle ,to the ends of the feed boxes, and the guides I to carry the scorer parallel to the sides ofthe feed boxes fol-'the purpose vset forth.

2. The combination of the frametl1evertilcal` shaft and cutter wheel mounted to revolve therein, the cutting knives secured insaid wheel, the feed boxes to feed the. blocks to the cutters, the frame H, fitted to slide radil ally in the cutterWheel-,th'c frame F carrying the scoring blades pivoted to vibratev Within `the frame l-l, the guides to carry the scoring devices parallel with the' sides ofA the feed boxes, and the ribs ai', arranged above the cutters` to discharge the slivers outside of the frame and away from the finished stock substantially as shown andV described.
