BENJAMIN IV. TUCKER, OF NEWARK, NEIV JERSEY, ASSIGNOR TO THE MARLES CARVED MOULDING COMPANY, OF PHILADELPHIA, PENN- SYLVANIA, A CORPORATION OF WEST VIRGINIA.

CARVlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 784,714, dated March 14, 1905.

Application filed April 1, 1902. Serial No. 100,904.

To all whom, it minty concern:

Be it known that I, BENJAMIN W. TUCKER, a citizen of the United States, residing in Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Oarving-lVIachines, of which the following is a specification.

This invention relates to machines for carving repeat ornaments or'a repeating series of ornamental characters in diaper on wood,moldings, or the like where two or more cutting members or sets of members, one or more for incising the contour of the ornament or a part thereof and another or others for making one or. more angular cuts meeting said incision or incisions, coact to carve the desired design.

My invention consists in improved mechanism for actuating the cutters at a high speed to incise the desired design upon a continuously-moving stock, in improved mechanism, in combination with the cutters, for rendering the angle of incision thereof adjustable, in improved mechanism for imparting motion to the cutters and to the stock, and improved structure, combination, and organization whereby the objects of this invention may be carried out in an automatic machine.

The objects of this invention are to provide a machine for automatically and continuously feeding stock and incising thereon ornamental characters in a repeating design, to provide means for accomplishing this result in a series of steps continuously which will result in a finished product, and to provide adjustable and substitutive parts in said machine whereby stocks of various size and form may be accommodated and designs of varying pattern may be incised.

I have illustrated my invention embodied in a carving-machine in the accompanying drawings, in which like reference characters refer to like parts throughout the several figures.

Figure 1 is a side elevation; Fig. 2, a plan view; Fig. 3, a rear end view; Fig. A, a vertical section on line w of Fig. 2; Fig. 5, a vertical section on line y y of Fig. 2, showing stock-guide and counter-shaft carriage broken away; Fig. 6, a detail plan of a tool-carriage, tool-head, and tools thereon, showing diagramframe has bearings 3 3 for supporting a continuously-revolving shaft 4:, driven by pulley 5 or otherwise, for carrying the gear 6. The

frame also has bearings 7 7 for supporting another continuously-revolving shaft, 8, carrying and driven by a gear 9, meshing with gear 6 and of equal diameter therewith.

The uprights A and B have upper portions of relatively circular form and supporting members beneath. Each of the uprights A and B is apertured at approximately the center of its circular portion, and an angular stock-guide 10 is joined to said uprights in alinement with the apertures therein. The stock-guide I0 is rectangular in cross-section and is secured to the frame in the position of the letter V. Upon the inner faces of the flanges of the stock-guide 10 are adjustably secured plates 11 and 12, turned up into flanges 13 at their outer edges. Bolts 14:, having flush heads countersunk in the plates 11 and 12 and provided with securing-nuts, are movable in transverse slots 15 in the flanges of the stockguide 10. These plates 11 and 12 form means for conforming the stock-guide 10 to the different sizes of stock to be operated upon, and the turned-up flanges 13 of the plates 11 and 12 retain the stock within the stock-guide throughout its entire length. This is a very necessary precaution in a machine of this character, as will be seen.

On the inner faces of the uprights A and B and adjacent the periphery of the circular portions thereof are fixed slide-rails l6 16, describing perfect arcs of equal radius about a point lying at about the apex of the stockguide 10. The slide-rails 16 are provided with T-slots 17 in their faces.

About the slide-rails 16 and concentric there with are located racks 18 18, securely bolted or otherwise secured to the uprights A and B.

Mounted between the rails 16 are countershaft carriages 19 and 20, slidably supported on said rails by guides 21 on their ends.

Each counter-shaft carriage 19 and is provided witha shifter-shaft22, mounted in journals 23 and 24 in said carriage. The shiftershafts carry gears 25, meshing with the racks 18 and hand-wheels 26 at either or both ends. By rotating the shafts 22 by means of the hand-wheels 26 the gears are caused to travel over the racks 18, and the counter-shaft carriages may be moved to any position upon the rails 16 independently of one another.

Bolts 27 are mounted in the end walls of each of the counter-shaft carriages opposite the T-slots 17 with their heads traveling within said slots, and the counter-shaft carriage may be rigidly sccu red in any position by tightening up on the nuts of said bolts on the inner side of their end walls.

As the counter-shaft carriages 19 and 20 slide upon rails 16 with fixed relation thereto,it will be seen that their angles of inclination to the stock-guide 10 is constantly changed as they are moved upon said rails.

Mounted, respectively, upon the countershaft carriages 19 and 20 in bearings 28 and 29 are counter-shafts 30 and 31, which have a constantly parallel relation to the shafts 4 and 8 with any position of the counter-shaft carriages 19 and 20.

The counter-shaft 30 carries and is driven by a gear 32. One end of a link 33 is journaled at 34 on the shaft 8 and at its other end is connected by a pivot-stud 35 to another link, 36, the opposite end of which link 36 is journaled to the counter-shaft 31 at 37. The shaft 8 carries a driving-gear 38. Two intermediate gears 39 and 40, mounted on studs41 and 35 on the link 33, transmit motion from the gear 38 on shaft 8 to the gear 32 on counter-shaft 30 in the relation of two revolutions of the counter-shaft 30 to one of the shaft 8.

The train of gearing 38, 39, 40, and 32 transmit power from shaft 8 to counter-shaft 30, and the disposition of this train of gearing on the links 33 and 36 renders the train extensible and contractile and capable of lendingitself to the varying space between the shafts Sand 30, occasioned by the path of the countershaft carriage 20 not being concentric with the shaft 8.

The counter-shaft 31 carries and is driven by a gear 42. One end of a link 43 is journaled at 44 on the shaft 8 and at its other end is connected by a pivot-stud 45 to another link, 46, the opposite end of which link 46 is journalcd to the counter-shaft 31 and 47.

Two intermediate gears48 and 49, mounted on studs 50 and 45 on the link 43, transmit motion from gear 38 on the shaft 8 to the gear 42 on counter-shaft 31 in the relation of two revolutions of the counter-shaft 31 to one of the shaft 8.

The train of gearing 38, 48, 49, and 42 and its disposition on the links 43 and 46 acts in the same manner and for the same purpose with reference to the counter-shaft 31 as the train of gearing 38 39 4O 32 on links 33 and 36 acts with reference to counter-shaft 30. Therefore it will be seen that the countershafts 30 and 31 revolve synchronously and are driven from and at double the speed of the shaft 8.

The shaft 4 is restricted against longitudinal movement by the abutment of the hubs of pulley 5 and gear 6 and a collar 51 with the bearings 3.

The links 33 and 43 are restricted against movement longitudinally of the shaft 8 by the hub of gear 38 and collars 52 and 53.

The links 36 and 46 are restricted against movement longitudinally of the counter-shafts 30 and 31 by the hubs of gears 32 and 42 and collars 54 and 55.

On the counter-shaft carriage 19 are mounted in bearings 56 and 57 parallel driven shafts 58 and 59, located beyond the ends of, perpendicular to, and in the same plane with counter-shaft 30. The shafts 58 and 59 are inclined toward the median line of the machine at an angle to the path of the countershaft carriage 19, which angle may be varied to a certain extent when the machine is built to adapt it to any particular class of work and for purposes which will hereinafter appear.

The shafts 58 and 59 respectively carry and are driven by driven miter-gears 60 and 61, meshing with opposite sides of drivingmitergears 62 and 63 on the ends of counter-shaft 30, which arrangement acts to impart the n10- tion of counter-shaft 30 to shafts 58 and 59 in the same direction and at equal speeds to that of counter-shaft 30.

The counter-shaft 30 is restricted against longitudinal movement by the abutment of the hubs of the miter- gears 62 and 63 with the bearings 28 and 29.

The shafts 58 and 59 are restricted against longitudinal movement by the abutment of the hubs of miter-gears 60 and 61 and collars 64 and 65 with the bearings 56 and 57.

On the counter-shaft carriage 20 are mounted in bearings 66 and 67 parallel driven shafts 68 and 69, located beyond the ends of, perpendicular to, and in the same plane with counter-shaft 31. The shafts 68 and 69 are inclined toward the median line of the machine at the same angle to the counter-shaft carriage 20 as the shafts 58 and 59 are to the countershaft carriage 19.

The shafts 68 and 69 respectively carry and are driven by driven miter-gears 7 O and 71, meshing with opposite sides of driving mitergears 72 and 73 on the ends of counter-shaft 31, which arrangement acts to impart the motion of counter-shaft 31 to shaft- s 68 and 69 in the same direction and at equal speeds to that of counter-shaft 30.

The counter-shaft 31 is restricted against longitudinal movement by the abutment of the hubs of the miter-gears 72 and 73 with the bearings 28 and 29.

The shafts 68 and 69 are restricted against longitudinal movement by the abutment of the hubs of miter-gears 70 and 71 and collars 74 and 75 with the bearings 66 and 67.

The counter-shafts 30 and 31 and miter- gears 62, 63, 72, and 73 thereon have the same direction of rotation. The miter-gear 60 meshes with the upper side of miter-gear 62 and the miter-gear 61 with the lower side of mitergear 63, thereby rotating shafts 58 and 59 in the same direction. The miter-gear70 meshes with the upper side of miter-gear 72 and the miter-gear 71 with the lower side of mitergear 73, thereby rotating shafts 68 and 69 in the same direction. However, it will be seen that this construction causes the pair of shafts 58 and 59 to rotate in opposite directions toward the stock-guide 10 and in the direction of the projected feed along the same.

Upon the upper ends of the shafts 58, 59, 68, and 69 are respectively set eccentrics 76, 77, 78, and 79, like in size, shape, and eccentricity.

The eccentrics 76, 77, 78, and 79 are set on the shafts 58, 59, 68, and 69 in planes lying parallel with and at equal distances from the counter-shafts operating said respective shafts.

e have seen that the shafts 58 and 59 are mounted to rotate synchronously. The eccentrics 76 and 77 are fixed on shafts 58 and 59 at the same angle to the plane of mounting of said shafts by keys 80, and therefore rotate synchronously. We have also seen that the shafts 68 and 69 are mounted to rotate synchronously. The eccentrics 78 and 79 are fixed on shafts 68 and 69 at the same angle to the plane of mounting of said shafts by keys 80, and therefore rotate synchronously.

Each of the eccentrics 76, 77, 78, and 79 is provided with a rectangular peripheral groove 84. Circular plates of greater diameter than the shafts and securable t0 the end of the shafts by machine-screws 86 serve to retain the eccentrics on their shafts and thekeys in their seats. A tool-carriage 87 is carried on eccentrics'76 and 77, and a tool-carriage 88 is carried on eccentrics 78 and 79. The toolcarriages 87 and 88 are each provided with tool-beds 89, having longitudinal T-slots 90 for the attachment of a tool-head 138 thereto and guide-recesses 91 and 92 at either end thereof.

Each of the recesses 91 and 92 is provided with a transverse guide 93 and retaining-plates 9 1, each having a corresponding transverse guide 95, said plates shaped to it and be secured by screws 96 to said tool-carriage to complete the perimeters of said recesses.

Split strap-blocks 97 embrace the eccentrics in the grooves 8 1 and are supported upon said eccentrics by the walls of saidgrooves.

The strap-blocks 97 are providedwith rectangular grooves in their opposite sides adapt- .ed to engage the transverse guides 93 and on the tool- carriages 87 and 88 to support the tool-carriages. Adjusting set-screws 98 are provided on the tool-carriages bearing upon the strap-blocks 97 for maintaining the embrace of the eccentrics by the strap-blocks and also to permit of the lateral adjustment of the tool-carriage relative to the eccentrics.

It will be seen that each tool-carriage being mounted on two synchronously-rotating eccentrics lying in the same plane will be given a translational movement in a circuitous path, and it will be further seen that as the shafts carrying the two eccentrics lie in a plane parallel to the stock-guide the tool-carriage will at all times be parallel with the stock-guide.

It has been pointed out that the pair of shafts 5'8 and 59 and the pair of shafts 68 and 69 rotate toward the stock-guide 10 in the direction of the projected feed along the same, and it will therefore be clearly seen that the tool- carriages 87 and 88, carried by the said pairs, will be given a circuitous movement toward the stock-guide 10 in the direction of the projected feed along the same, while the parallelism existing between them and the stock-guide will not be destroyed.

It is intended that the tool-carriages shall approach the stock-guide 1O consecutively that they may not interfere and at constant intervals to secure a uniform movement, and as this periodicity would be destroyed by moving one of the counter shaft carriages a greater distance on the slide-rails 16 to give its tool-carriage a greater angle than the other the studs 6L1 and 50 of gears 39 and 12 are removably mounted in the link 13, and one of the gears 39 or 4:2 is adapted to be removed from the train while the adjustment is taking place to be again inserted therein to maintain the desired periodicity of movement of the tool-carriages.

On the outer face of the upright A, at either side of the aperture therein, before referred to, two shafting-brackets C and D are rigidly secured by bolts 99, and on the outer face of the upright B, at either side of the aperture, hereinbefore referred to, two shafting-brackets E and F are similarly secured.

A shaft 100 is mounted in bearings 101 and 102 in the shafting-brackets C and D and carries and is driven by a miter-gear 103, meshing with a miter-gear 104 on the shaft 8 and driven at the same speed as shaft 8. A gear 105, fast on shaft 100, drives, through a gear 106, a shaft 107. The shaft 107 carries a feedroll 108, having a peripheral groove 109, conforming in cross section with that of the stock guide 10. The highest point of the groove 109 lies directly in alinement with the stock-guide 10 to engage stock lying in and projecting from said stock-guide.

The feed-roll 108 rotates at half the speed of the shaft 8, and consequently one-fourth the speed of the shafts 58, 59, 68, and 69.

IIO

The active gripping periphery of the feedroll 108 is to be made four times the length of the chord of the are formed within the profile of the stock by the path of a single point in the cutting edge of the cutter. Motion is transmitted from a gear 110 on shaft 107, through an idle gear 111, to a gear 112 on a shaft 113, mounted in bearings 114 and 115 in the sl1aftiug-brackets O and l).

The shaft 113 carries a feed-roll 116 identical in size and form with roll 108 and rotates at the same speed and in the same direction as roll 108. The highest point of the groove 109 of feed-roll 116 lies in alinement with the like point of that of roll 108 and the stock-guide 10. Two presser- rolls 117 and 118, identical in size and form, having peripheries substantially conforming to the profile of the stock to be operated upon and having active gripping-peri pheries of the same diameter as those of feed- rolls 108 and 116, are mounted in adjustable bearings 119 and 120 in shaftingbrackets (l and l).

The bearings 119 and 120 of presser- rolls 117 and 118 are provided with downwardlypressing springs 121 and 122 and are adjusted to vary the pressure by adjusting- screws 123 and 124, working on spring- caps 125 and 126 and mounted in retainer-plates 127,1'e1'novably secured to the brackets (J and l).

The miter-gear 103 meshes with the mitergear 104 to give the rolls 108 and 116 a movement at their gripping-points in the direction of the projected feed of the stock.

A stud 128 is mounted in the shafting-brackets E and carries a miter-gear 129, driven in the same direction as gear 103 by a miter-gear on shaft 8.

It will be seen that the miter- gears 103 and 129 mesh with the miter- gears 104 and 130 on opposite sides of shaft 8, rotating miter- gears 103 and 129 in the same direction.

An ejector-roll mechanism identical with the feed mechanism described as mounted on shafting-brackets (J and II) is mounted on shafting-brackets E and F and driven from miter-gear 129 in the same direction. The elements of said ejector mechanism being identical with those of the feed mechanism already described have been given the same reference characters for the sake of brevity.

A rotary brush 131 is mounted on a spindle 132, mounted in a bearing 133 in a support 134, in turn secured to the shafting-brackets E and F. A sheave 135 is mounted on the spindle 132 and is driven by a belt 136 "from a sheave 137 on shaft 8. The brush 131 serves to brush out the chips from the stock before it passes to the ejector-rolls on brackets E and F.

The shaft 8 is restricted from longitudinal movement by the hubs of gears 104 and 9 and sheave 137.

The tool-heads 138 are adapted to be clamped to the tool-beds 89 by bolts 139, the heads of which bolts 139 "engage in the T-slots 90, mounted in said head.

Tool-shank recesses 140 in the lower edge of the tool-heads 138 accommodate the shanks 141 of the tools 142, which are rigidly secured in said recesses 140 by binding-screws 143. The adjacent binding-screws 143 are disposed upon the tool-head 138 out of alinei'nent with one another to admit of the application of a wrench thereto.

The shanks 141 of the tools 142 are made long and thin to admit of a certain amount of spring or give, the reason for which will hereinafter appear.

The first sixteen tools at the left (see Fig. 6) are made shorter and are set in a higher plane (see Fig. 7) than the second sixteen at the left and are designed to cut a preliminary chip, while the second series of sixteen cut a deeper or finishing chip.

The distance between the centers of the first and second series of tools is equal to the length of the path of the tool-carriage, which is shown by the dotted circles 144 and 145, showing the path of a single point in the cutting edge of one tool 142.

The tool traverses the are between the points (a and con dotted circle 144 in cutting the finishing-chip at the same time that the stock travels along the chord between said points. The speeds of the tool and stock are exactly equivalent at the points a, b, and c on the dotted circle 145, and therefore the tool travels uniformly with the stock at these points; but between these points there is a slight discrepancy between the velocities of the tool and stock, owing to the angularity of arc and chord, but any ill effects of which, however, is counteracted by the springing or giving of the thin tool-shank.

Tools of various forms are used for cutting different designs of ornaments, and a separate tool-head is provided for each design in which the distance between the individual ornamental characters is different, in which cases the tool-shank recesses are disposed at various distances apart.

The tools forming the first series make a series of rough incisions at the same time that the second series of tools make the finished cuts, and upon the next succeeding circuit of the tool-carriage, the stock having been fed along in the meantime, the finishing series of tools exactly register with the rough cuts previously made and finish them simultaneously as the roughing-tools make the next succeeding series of rough cuts.

The gear-trains operating the tool-carriage are set to bring one carriage to its cutting position a little before the other, so that the tool edges will never interfere, and the tool-heads are so set upon the carriages that the series of roughing-tools of one will register with and cut out the chip incised by the roughing series of the other and the same as to the finishing series of tools.

The inclination of the shafts carrying the eccentrics of the counter shaft carriages should be ascertained in building the machine with regard to thescope of angular adjustment of the tools desired.

When a stock of difierent profile is to be used, the presser-rolls, which are movable, should be removed and others substantially conforming to the profile of the stock, but having the same active gripping periphery, substituted.

Larger eccentrics may be used to give the tool-carriages a greater throw; but when this is done the feed and presser rolls should be proportionally changed.

The tool-beds can be constructed of greater length, and other series of toolsfor instance, for making additional rough cuts or superimposed ornamental cutsmay be added.

The power might be applied directly to shaft 8, if desired, the form given being merely designed to remove the power-pulley to a more convenient position.
