blECIFICA'lION forming part of Letters Patent N 0. 694,758, dated March 4, 1902. Application filed October 26, 1899. Serial No. 734,319, (No model.)
To all whom it may concern.-
Be it known that I, HENRY W. LARSSON, a citizen of the United States of America, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Machines for Longitudinally and Diagonally Dividing or Stripping Ratan, Wood, &G., of which the following is a full, clear, and exact description.
This invention relates to improvements in machines for splitting or longitudinally dividing strips of ratan or other similar material in such a manner that the two divisions of each of the strips which are runth rough the machine are endwise tapered and the one constituting the complement of the other.
The invention more particularly relates to a machine for producing from a given crosssectionally-segmental-shaped strip of .ratau which is of substantially uniform width from end to end two divisions thereof, which as to the length of the strip are separated on a line which runs from the side portion at the one end to the opposite side portion at the other end and which splits are produced by being separated on a cutting or dividing plane which is substantially radial to the apex of the stock at all points throughout the length thereof. The divisions produced as aforementioned are especially applicable for employment in making up stocks or bodies of whips.
The invention consists in the combination and arrangement of mechanisms or devices, as hereinafter set forth, and also in the construction of certain of said devices, and all substantially as covered in the claims.
The machine as I have constructed it in an improved and satisfactory form is illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the machine. Fig. 2 is a plan view of the same. Fig. 3 is a cross-sectional view vertically as taken on the line 3 3, Fig. 1. Fig. 4 is a view on a somewhat-larger scale of the carrier for the stock-dividing knife and the means for imparting a rotational reciprocatory movement thereto, such parts being indicated as inclosed within a casing suitably constructed therefor. Fig. 5 is a vertical section as taken relations to the knife.
on the line 5 5, Fig. 4, guides which are forward and also to the rear of the knife and its carrier being shown as in their appropriate Fig. 6 is a perspective View of the guide, which is located longitudinally to the rear of the knife. Fig. 7 is a front end view of the guide for the stock,
which is longitudinally arranged and rotated forward of the knife. Fig. 8 is a side view of the preferred form of the knife employed in this machine for dividing the longitudinal strips or stock. Fig. 9 is a cross-sectional view on line 9 9, Fig. 8. Fig. 10 is a perspective View of the initial guiding and feeding device for the stock. Fig. 11 is a horizontal sectional and plan view of mechanism located below the bed or table of the machine and actuating the separable mechanism comprised in the feed for the strips at the rear end of the machine. Fig. 12 is a sectional view of parts in detail as taken on the line 12 12, Fig. 11. Fig.'l3 is an elevation of the feed-rolls as seen at the front end of the machine look ing rearwardly. Fig. 14.- is a horizontal sectional view of the parts shown in Fig. 5 and as taken about on the line 14- l l. Fig. 15 is a side view of a segmental-shaped strip or length of raian or other material such as this machine is adapted todivide. Fig. 16 is a plan of the strip, showing by dotted line the oblique orinclined line of division. Fig. 17 is a series of cross-sectional views showing at the ends the segmental cross sectional form of the strip and intermediately crosssections of the strip divided as taken on the section-line projected from each of these sub views. Fig. 18 is a plan view showing the strip as half split and the relative location of the knife.
Similar characters of reference indicate corresponding parts in all of the views.
In the drawings, A represents the frame or table of the machine, having suitable journals formed on or affixed thereto, the horizontal transversely-arranged main shaft B having the driving-pulleyB thereon.
1 represents whatI term the front end or forward part-of the machine; 2, the rear end portion thereof; 3, the front side, and i the rear side, of the machine.
0 represents the location of the casing in which; is mounted the annular carrier or holder for the knife a.
At D is located the initial guide and feed mechanism into which the segments are manually introduced, in line with and to the rear of which is the set of feeding-rolls E. Next to the rear of and in line with the said feedingrolls E and which is ahead of and also in line with the knife a is the guide F. To the rear of the knife in the line of feed of the stock is another guide G, while to the rear thereof is the set of feeding-rolls H, the upper ones of each pair being separable.
Having in a general way referred to and indicated the location of the various devices or mechanism comprised of important portions in the organization of this machine, a more detailed and definite description of the various devices and mechanisms will be now given. I
Referring now to the first set of feed-rolls and the means for imparting thereto their rotational feeding motion in the same direction, it will be seen that the feed-rolls are arranged in upper and lower pairs, six of each being here represented, although the number may be greater or less, as desired. The lower rolls 20 are peripherally V-grooved and have their arbors 22 mounted in stationary bearings. The upper feed-rolls of this set E are, as indicated at 23, in the form of circular plinths or comparatively thick disks and have their peripheries adapted to sink but part way into the V-groove peripherally formed in the fellow feed-wheel. The arbor 24 for each upper feed-roll 23, which is extended toward the rear side of the machine, has its rear end pivotally mounted, as shown at 25 in Fig. 13, whereby the feed-roll 23. may have a rising-and-falling and self-adjusting movement to conform to the top or back of the segmental strip to be run therethrough. The mounting for each set of the feeding-rolls has toward the front side of the machine, but located next back of the roll 23, the upstanding duplicated ear-lugs 26, pivoted in which is the elbow-lever 27, the short arm of which is rounded and is in bearing against the top of the arbor or journal-shaft for the roll 23, which runs loose thereon, so, that said shaft may have a rising-and-falling motion. The spring 28 is applied on each angle-lever 27 to exert a downwardly-forcing pressure on the roll-carrying shaft 24. The shaft 22 for each lower V-grooved roll 20 has a spur gear-wheel 30 affixed thereon, and the several gears 30 30 are driven the one from another byintermediate gears 32, while motion is imparted to this train of gearing so that all of the lower rolls are positively driven in the same direction and at the same speed by the gearing interposed between one of the gears 30 and the drivingshaft B of the machine, and which will be pointed out as comprising a spur gear-wheel 33 on the shaft 22 for the lower feed-roll, a spur gear-wheel 34 on the main shaft, and an At the front end of the machine, preceding the series of feed-rolls above described, is the initial feeding device D for the segmental strips x, which is shownmore particularly in Figs. 1, 2, and 10. This device D comprises a standard 37, adapted to slide horizontally longitudinally in the way 38 therefor, and this standard is equipped with a portion above its base, which is fitted in the slidew'ay with the upwardly-open longitudinal channel 39, which transversely is of aV shape. Pivoted on the standard 38 is the dog or pawl 40. This is inclined downwardly and rearwardly, its lower end terminating for a pressure-bearing, as exerted by the spring 42 on the strip 00, and all so arranged that the end of the strip may be forced to the nipping action as exerted by and between the pawl 40 and the adjacent V-grooved part. The strip being once entered between these parts may have only a progressive movement toward the rear end of the machine, for it will be apparent that any tendency to draw the strip in the reverse direction will result in the same becoming clutched.v The periodical reciprocatory movement is imparted to the feed device D by the thrust-rod 43 in one direction and the spring 44 in the other. The said thrust-rod has its one end pivoted at 45 to the sliding part 37, its other end being forked to receive a guiding engagement with the flanged washer 46, provided at the upper projecting end of the worm-wheel shaft 38. The thrust bar or rod 43 has a depending projection 47, which the scroll-cam 19 engages. of the shaft 38 the feeder D will recede toward the right-hand end of the machine, when suddenly falling off the abrupt part of the cam (indicated at 19 it is left subject to Once to every rotation the reversing impulse of the spring 44, which drives it forcibly and sharply longitudinally toward the feed-rolls E. By placing the end portion of the strip in engagement through the feeder D the impulse. of the latter will be to project the same forcibly between and to the nipping action of the paired rolls 30 and 32 in the roll-feed mechanism E. The strip being carried through the set of feedrolls E enters the V-guide F, the same comprising an upright 48, having within its top the channel or groove 49, the base of which is downwardly convergent or of a cross-sectional V contour. The short bar or pressure member 50 is pivotally hung at its forward end, as shown at 52, to upstanding ear-pieces provided on the part 48, the said member 50 having the downward rearward inclination and forced down with a yielding bearingby the spring 53.
The knife a is mounted in the knife-holder orknife-carrier J, which as a whole is of an annular form, the knife being'located within and extending diametrically crosswise of the opening within the lrn'ife-carrier. The center of the carrier is exactly or approximately coincident with the common longitudinal horizontal line extending through the apexes of the channel 39 in feeder D, the
bases of the V-grooves at the tops of the roll-'' ers 2O of the feed-roll me'chanis'inE, and
the base of the V-groove '49 in the guide F, and the knife which intersects the said'axial. center of the knife-carrier has its'len'gth radial to such center, and the carrier'having a capability for rotational movement about said center by means to be hereinafter described causes the knife to assume difi'erent radial po sitions,'as it has its traverse bodily across the width of the V-shaped strip or segment being 'fed past, and to be divided on a'sligh'tlyoblique line by the knife.
The knife-carrier comprises the an n ular section 60, having atits inner margin the annular flanges 62 62, projecting beyond theface of the ring'shaped section. The one flange 62 bears peripherally on the circular wallcomprised as the boundary of the opening within the casing C, the annular clampingplate 63 constituting the peripheral bearing for the opposite one of said flanges 62. Within the ring-section is a secondary removable ring section 64, the same having at its rearside the flange 65, which overlaps the edge of the adjacent flange 62 of part 60.
66 represents a-clamping-rod having its shank passed through an opening therefor in the ring-section 64: parallel with the axisof such part, such rod having at its forward end the angular engagement member67 and at its rearwardly-located screw threaded end receiv'es the clamping-nut 68. As the flange overlaps both the flange 62 of part 60 and the clamping-ring plate 63, the single clamping gitudinal aliued ways 73, (shown'in Figs. 5
and 14,) in which are fitted the movable blocks 74. These blocks have inthe inner ends thereof, which are located toward each other, sockets 7 5 for the receptiontherein'of the trnnnions or pivot-constituting members '76 76 of the knife or. v
Inasmuch as I claim novelty in the cutting blade or knife anda support for the knife on which the same is pivoted with the cutting edge located back of the pivotal line,I do not wish to be limited to any specific form and manner of mouutingof the knife inac'cordance therewith, but an entirely practical, operativ cgandsatisfactory constructionand arrangement is shown in Figs; 3, 4, 5, 8, 9, and let, in which the blade a of the knife has at its ends the integrally-formed bars or members a a projected forwardly beyond -the cutting edge of the knife. The pi'v'ot members I or trunnions 76, the commonline of which is parallel with the length of-the knife,l1ave their'common center'ahead of the cutting edge of.
The aforementioned rack-bar 70, which gives the partial rotary and reciprocatory motion to the knife-carrier, has its rectilinear motions imparted thereto by the engagement with the upstanding cam-roller 77 thereon of the scroll-cam 0, whereby as the radial widening-cam has its revoluble'movementit will force the rack-bar 7O rearwardly, and the spring a will retract the rack-bar forwardly when the drop or abrupt part of the cam c has come opposite the said roller. Thus as the strip has its progressive course in a V straight-line through the machine the knife having the swinging bodily motion will be carried with its forwardly-directed cutting edge against the one convergent side of the strip at or near its forward 'end, and the knife will by reason'of its peculiar motion emerge from the strip at its other end portion andjat the opposite convergent ,side thereof, dividing the strip into two sections, both of which 7, at all points in their lengths are segments, as insured by the knife having its position at.
all stages of its swing in'a line radial to the apex of the segmental strip to be'divided and of the guides throughwhich thestrip is'fed or conducted.
The mounting of theknife for the secondary oscillatory movement is found to be a' matter ofzgreat importance in thepractical working of this machine, especially where it IIO is tobe employed for producing" duplicated endwise tapered cross sectionall y segmentshaped divisions from one of the segments w of ratan, forthe reason that the cutting edge ofthe knife will most readily makeitsinitial incision or take into the strip' mfat the one side, and after having entered andwhilethe cut- I ting or dividing action is "progresslng the knife may conform to inequalities of the grain and prevent the 'edge of the knife from there- I by becoming turned or broken, and yet in practice the splitting-line diagonally of the strip which is maintained is singularly.
straight, continuous, and clean, no percept? ible undulations at the surfaces following or I opened'up by the division as efiected by the 'knife-being-found. 1
Protracted use of the dividing mechanism described has been had, and notwithstanding I the fact that the knife a, constructed and mounted as shown, was made of inferior and comparatively soft steel and used when in a comparatively dull condition the splits or subsections 00 were brought forth out of the machine with the sharpest and cleanest surfaces imaginable, even at their extremities, where the thickness was no greater than a thin shaving and where the stock was most flexible.
On some classes of work where the greatest accuracy of the division is not necessarily so great as in making splits or tapered segmental sections for whips the knife may be em ployed by being mounted on the holder,which gives it its traverse relatively to the strips to be divided on an oblique line without necessarily being pivotally mounted on or in the holder for the secondary self-conforming oscillatory motion which has been described; but hence I do not confine myselfabsolutely to the employment of the knife which is pivotally mounted on the holder, for under certain circumstances I have acquired successful results when the knife was non-pivotally mounted.
The guide G,which likewise is of the V shape in cross-section, has its position and arrangement longitudinally to the rear of the knife, and a detail View of this appliance is given in Fig. 6. This guide advantageously is constructed with the extension 80, which is projected through the knife-carrier back of the knife and is secured on and supported by the upright 48, in the top of which .is comprised the V-guide, heretofore designated by F. This device G is provided for the purpose of keeping the split halves of the strip a: together and for insuring the conducting thereof with certainty to and between the rolls comprised in the feeding device H, which is for carrying the strips out of the machine and insuring positively the continued longitudinal movement thereof, especially at the latter part of the operation, at which the end portion of the strip lastapproaching the knife and after it has passed the series of feed-rolls E will even then be carried to and past. the knife. These rolls are substantially duplicates of the rolls 20 and 23 hereinbefore mentioned, the lower ones being V-groo ved and running in fixed bearings, while the'upper disk rolls 23, mounted for yielding movements upwardly against the pressure of the springs 28 in the same manner as are the corresponding disk rolls 23 of the set E, have means combined therewith for positively periodically elevating them in time to permit the entrance between them and the V-rolls therebelow of the forward now-divided end of the strip 00.
The means for imparting the separating movements of the upper disk rolls will be now described.
An upstanding vertically-movable rod or bar 82 carries at its upper enda cross-bar 83, which engages onto the collars provided at the outer or front ends of the bars 24-,on which the disk rollers are journaled. The vertical rod 82 has on its lower end the cam face or incline 84, adjacent which is located the extremity of a lever 85, which is pivotally mounted at 86 and arranged to swing in a horizontal plane under the bed or table of the machine. The extremity of the said lever 85, adjacent the part 84, is beveled orinclined, as indicated at 87, to work easily for a crowding action against the cam-incline 84. A projection 88, upstanding above the top face of the worm-wheel 37, once in every revolution of said wor m-wheel,which corresponds to each complete operation of the machine, swings the lever into the position indicated by the dotted lines in Fig. 11, and thereby insures at the proper instant the separation of the.
upper disk rolls 23.
