To all whom it may concern:
Be it known that I, FRANCIS H. RIoHARDs,
a citizen of the United States, residing at -new and useful Improvements in Carving-g Machines, of which the following is a specifi-j My present invention pertains to ma-; chines for carving repeat ornaments or a re-} peating series of ornaments on wood, mold-i ings, or the like, and relates to that class of? carving-machines wherein two or more tools? or chisels coact to incise stock to produce thej contour or configuration of said ornamentsll In machines of this character speed andl durability are especially sought for; and some of the objects of the present invention are to provide a carving-machine of improved design and practical construction conceived} with the express purpose of improvement; and advancement to these ends.
This invention consists in those novel fea-; tures of construction and organization em-i bodied in the machine illustrated, described,l
specification, and claims. A I have illustrated one embodiment of my,
invention in a carving-machine of the inter-j mittent-feed type; but the same may in principle and in many 'detailed features be? applied to other types of carving-machines orj machines designed for other work, but having;
more or less analogous operations. Like reference characters denote like parts} 1 throughout the several views of thedrawings. Figure l-is aside viewof the machine,f
showing the base or frame sectioned'on'linei 1 frame cut away, and Fig. afldetail in spective of the superstructure. I
:20 ref Fig. 3; Fig. 2, a plan view, Fig.3, a vertical cross-section on line y y of'Fig. 2;} Fig.4, a front view showing front wall of. per-;
Referring to the drawings, the-machine is mounted and assembled on a box-like frame A one-piece crank-shaft 2 is mounted longitudinally of the frame A in a bearing 3 in thefront wall and a bushing-bearing 1 in the rear wall, said bushing-bearing 4 being designed to close an aperture 5 in said rear wallmade large enough-to permit of the in- 'sertion of the crank-shaft- 2. The crankshaft 2 projects withoutthe bearing 4 and is J provided with a fast driving-pulley 6, thehub .of which pulley: and a fast collar 7,-abutting 2 opposite sides of the bearing 4, restrict the nected with the crank of crank-shaft 2 by a connecting -'rod 11. A stock guide 12 .is mounted on supports 13 13, upstanding from the top of the frame A and lies parallel to and directly'above the shaft 2. The stock-guide 12 forms a right angle in cross-section and is set with the flanges of said angle equally inclined from the perpendicular. The supports 13, together with the stock-guide 12, are removable from the frame A. A plate 14 is secured to the top of the frame A bybolts 15 and carries oppositelyinclined slideways 16 and 17, set one before the other closeto the stock-guide 12 and each inclined at approximately the same angle-as that of the flange of said stock-guide next thereto.
- a slide 19 is mounted in the slideway 17.
Both of the slides 18 and 19 are provided with tool:beds 20 on their upper surfaces, and'toolclamps 21 serve'as meansfor securing the tools 22t0 said tool-beds 20. Studs 23 and 24'project laterallyfrom either side of the cross-head 10, directly 'beneath the center lines of the slides 18 and 19, respectively. A connecting-rod 25 is jointed to a lug 26, de- "pending from the under side of the slide 18 and connects said slide with the stud 23 on the'crOss-head 10. A connecting-rod 27 is I jointed to a lug 28, depending from the under with the stud 24 on the cross-head 10. The connecting rods 25 and 27 pass down throughapertures 29 in the plate 14 and aperterior of the frame A. The tool-beds 20 are raised above the lower portions 31 of the 7 slides 18 and 19,'so as to bring the tools 22 to the correct height toincise a piece ofstock 32, shown lying in thestock-guide 12. The stock-guide 12 adjacent each of the tools is provided'with-blocks 33', which are secured to the stock-guide by screws 52and have interiorsurfaces corresponding to the configuration of the stock, thus forming an inclosed stock-guide except at the points where; the
mounted to slide in the guides 8 8 and is con- I It will be seen that the stock-guide 12 lies side of the slide 19 and connects said slide 5 tures in the top of the frame A'to the infast on a shaft 36, mounted in a bearing 37,
I projecting from the stock-guide, and a bearing 38, supported in the top of the frame A.
- half.
The shaft 36 passes through the bearing 38 to the interior of the frame A, where it is geared, through bevel- gears 39 and 40, to a horizontal transverse shaft 41, mounted in bearings 53 and 54 in the walls of frame A.
An oscillatable lever 42 is loosely pivoted on the shaft 41 directly above the driving-shaft 2 and carries a pawl 43, adapted to engage a ratchet wheel 44, fast on shaft 41. The pawl 43 is maintained in contact with the ratchet-wheel 44 by a spring 45. A connecting-rod 46 is jointed to the lever 42 and has a bifurcated lower end, which embraces the driving-shaft 2. Aroller 47 is loosely mounted on a stud 48, projecting from the connecting-rod 46 and is adapted to ride upon a heart-shaped cam 49, fast on the driving-,
shaft 2. A spring 50, connected from the lever 42 to the wall of the frame A, maintains the roller 47 in constant contact with the cam 49. A block 51, similar to blocks 33, is secured to the stock-guide directly above the feed-roll 34 and serves to keepthe stock in position to be engaged by said feed-roll.
The operation of the machine is as follows: Stock is placed in the stock-guide 12 and under the block 51 when it is engaged by the feed-roll 34 and fed forward intermittently. As the driving-shaft 2 is rotated the cam 49, contacting the roller 47, carries the connect ing-rod 46 upward, and the pawl 43, engag-- ing a tooth of the ratchet-wheel 44, rotates the shaft 41 during this movement. This rotation of the shaft 41 is communicated to the shaft 36 and feed-roll 34 through the gears 39 and 40, accomplishing the feed of the stock during a half-revolution of the'driving-shaft '2. During the other half-revolution of the driving-shaft 2 the connectin rod 46 is moving downwardly and the paw 43 is returning idly over the tooth of the ratchet-wheel 44, allowing the feed-roll 34 to remain at rest, accomplishing a eriod of non-movement of the stock. As t e driving-shaft 2 rotates, the slides 18 and 19 reciprocate simultaneously, the tools 22 reaching, entering, withdrawing, and leaving the stock lying in the stock-guide 12 during one-half revolution of said driving-shaft 2 or a little less than one- During the remaining half-revolution of the driving-shaft the tools 22 complete their outward movement and move forward to the stock again entirely without the profile of the stock. The crank of the driving shaft 2 and the heart-cam 49 are set with such relation to one another that the feeding movement shall take place during that halfrevolution when the tools are entirely without the stock, and the movement of the tools within the profile of the stock in making the incisions and leaving the stock shall take place during that half-revolution when the feed-roll 34 is at rest. The distance fed at each feed of the roll and the distance between the tools is such that an incision made in the stock by the first tool will exactly register with some succeeding position of the second tool during the period of rest. It will therefore be seen that the tools operate simultaneously, but make the contradistinctive incisions of separate repeats at each stroke, that )ortion of the stock operated upon by the irst tool assuming at some succeeding stroke the position assumed by that portion of the stock which was operated upon by the second tool when said first-mentioned portion was operated upon by said first tool. The tools act in transverse intersecting lines, which, in the. form herein illustrated, are in parallel planes, and the working strokes of the tools are so timed for cooperation with a relatively intermittently advancing feed motion that they will repeatedly cooperate in the production of a completed design at the intervals of the measure of the repeat, the measure of the advance of the stock relatively to the tools being the distance apart of the centers of the repeat designs, each tool at each change of position of the stock performing its portion of the cutting of a design. The two carriages 18 and 19, it will be noticed, are of such length that they extend both above and below the stockguide throughout the stroke, giving a very long purchase on the gibs. It will also be noted that the connecting-rods connecting the cross-head with the carriages are jointed to the carriages directly beneath the tool, so that the purchase is applied as close to the point where the resistance occurs as possible and prevents, in a great measure, binding of the carriages in the guides. the crank is applied to the cross-head vertically and any pounding action will be of a vertical nature and will be taken up by the foundation and will not be the cause of lat eral vibration. The power is applied to both carriages at the same time on opposite sides of the central line and the thrusts will counteract one another and prevent lateral vibration. The tools and. carriages being set side by side and not 0 aerating upon the same point on the stock, allow the tools to be actuated simultaneously without bringing their cutting edges into contact.
It is obvious that various changes may be made in the details of construction and gen- .eral arrangement of the parts to adapt the machine to particular kinds of work'wi-thout departing, from the spirit of the invention.
