SPECIFICATION forming part of Letters Patent No. 384,995, dated June 26, 1888, Application filed January '7, 188 8. Serial No. 260,065. (No model.)

To all whom it may concern.-

Be it known that I, STEPHEN F. Mooun, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and 'of the complete device.

useful Improvements in Carving-Machines; and I do hereby declare the following to be a full, clear, and exact description of said inven tion, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention, to be hereinafter claimed, relates to the peculiar form and construction of the various parts of my mechanism and to the location, combination, and arrangement of those parts in the complete device, in the manner and for the purposes hereinafter to be described.

In the drawings, Figure l is aside elevation Fig. 2 is a front elevation of the same device. Fig. 3 is a plan on line X X of Fig. 1 of the swinging arm and lower arm of the frame in which the cuttingtool is carried and operated. Fig. 4 is a central vertical section of the joint connecting the swinging arm and the thereon supported frame and of adjacent parts of the mechanism. Fig. 5 is a central vertical longitudinal section of a portion of the arm of the frame that supports and carries the carving-tool, with the carvingtool and its carrying and driving mechanism in connection therewith. Fig. 6 is a detail of the device for adjustably securing the swinging arm to its supporting-hinge. Fig. 7 is an elevation of the guide in the upper arm of its supporting-frame, a part being broken away to show interior parts.

The same reference letters and figures refer to like parts in all the views.

The mechanism for supporting and operating the cutting-tool issupported in brackets B and Osecured to a post, A, or studding of the building. A vertical shaft, 1, is supported and rotates in journal-bearings in the brackets B and C. This shaft carries a fixed bandwheel, 2, whereon theband 3 runs which connects the mechanism with the power-supply. Aswinging arm, 4-, is supported by means of a pivoted hinge, 5, in the lower bracket, B. The arm 4 is so pivoted in the bracket B as to be adapted to swing horizontally through the entire are in front-of the post A, and is adjustably secured to the hinge 5 by means of the set-screws G 6, turning through the slots 7 7 in the enlarged end of the arm 4 into the hinge 5, whereby the arm may be tilted from the perpendicular, either to right or left to a limited extent, as desired, wherebyI am able to get a proper alignment of the arm 4 and a certain amount ofunder-cut in carving, which is sometimes very effective, especially in figures in considerable relief.

Sometimes when heavy work is being done, and at all times, if desired, a brucc'rod, S, is secured at one end to a flange or bracket, 9, rigid on the arm 4, and at the other end to a collar,-10, supported and movable about the shaft 1. The rod 8 is inserted in the bracket 9 and collar 10 by reverse screw-threads at its respective ends, whereby by its rotation it is loosened or tightened in its respective seats, and sufficient play is thereby provided for the tilting of the arm provided for in the adj ustable bearings between the arm and binge 5. At its outer end the arm a on its upper surface is provided with an enlarged horizontal face, 11, whcreon is supported and swings horizontally the thereto-pivoted hinge 12, having a corresponding bearing-face. This hinge 12 is integral with and a part of the upright standand 13. In front of the standard 13 and rigidly secured thereto is an upright p0st, 14,

which post is provided at its top and bet 1 tom, on both sides, with recessed diamond shaped bearings 15 15, forming ways for supthe toolsupporting frame. This frame con- 8.. 3 porting and guiding the vertical movements of sists of the lower tool-carrying arm, 16, and i of the upper gnidecarrying arm, 17, which arms are rigidly connected together, but at a distance apart, by the rods 18 18. This frame is provided with adjustable bearings orguides the upper side of the lower arm and against the lower side of the upper arm, respectively. A vertical alignment of this frame with reference to its supporting-postljt may be secured by the adjustment of the guides 19 19 in or out in their bearings in the arms 16 and 17, and securing them therein by the set-screws 25, turning through the arms 16 and 17 against them. The outer end of the arm 16 terminates in a bracket or globelike shield, 26, in which a small vertical shaft or spindle, 27, is supported and journaled, which spindle in its lower end carries the carving-tool 28. The bracket 26 is preferably constructed in the form of a spherical shield having one side broken away, in which form it provides an upper and lower bearing for the spindle 27, and at the same time is a shield for the fixed pulley 29 on the spindle 27, and is adapted to serve as a knob or handle for the operator whereby to guide and manipulate the carvingtool. The lower end of the spindle 27 is constructed as a chuck, split to receive the end of the tool 28 therein, which tool is held in position by being clamped therein by the nut 30, turning on a screw-thread on the spindle 27. To obviate friction, the spindle 27 is provided with beveled bearings 31 3l,fitted into beveled hearings in the plug-nutjournals 32 32, turning in the bracket 26. For lubricating purposes the upper plug-nut journal 32 is pro vided with an oil-cup, 33, and an aperture therefrom through the plug-nut to the bearing of the spindle.

For driving the carving-tool a band-w heel, 34, is fixed on the shaft 1, and a belt, 35, running thereon, runs also on a band-wheel, 36, fixed on a shaft, 37, which shaft 37 is pivoted in the outer end of the swinging arm 4, and a pulley, 38, rigid on the shaft 37 carries a belt, 39, which also runs upon the pulley 29, fixed on the tool-carrying spindle 27. An intermediate belt-t-ightening pulley, 40, supported and rotating on an arbor, 41, is located between the pulleys 29 and 38, and the belt 39 runs on said pulleys 29 and 38, and runs also on the pulley 40, and is arranged to be guided and tightened thereby. For this purpose, and to get the greatest possible amount of adhesion of the belt 39 to the pulley 29,to avoid the slipping of the belt thereon, I preferably cross the belt between the pulleys 29 and 40, as shown at 42. For the purpose of adjustment the arbor 41 is made adjustable in the arm 16 longitudinally in the slot 43, in which the arbor is inserted, and to which arm it is secured by means of a screw-threaded nut, 44. This arbor is constructed of a central bolt, 45, a collar, 46, bearing on its upper surface against the arm 16, and at its lower end beveled to receive a corresponding bearing of the pulley thereagainst, and a lower collar, 47, also provided with a beveled upper end adapted to receive a corresponding beveled bearing of the pulley 40 and the two nuts 48 and 44 at its respective ends.

It will be noticed that the diameter of the aperture through the center of the pulley 40 is somewhat greater than the diameter of the bolt 45, and that the pulley is so constructed as to have bearings only on the beveled ends of the collars 46 and 47, respectively, whereby the least amount of friction is secured in connection with proper steadiness of the pulley.

Directly above the tool 28, and in the outer extremity of the arm 17, a guide, 49, islocated and adjustably secured. This guide is a small rod or spindle held upright in the arm 17, through which it is inserted. For the purpose of adjustment this spindle 49 is fitted nicely, but movable lengthwise, in a sleeve, 50,which sleeve at its upper end is provided with a screw-thread, whereon a nut, 51, turns, which nut is adapted to bear against the top surface of the arm 17. The sleeve 50 at its lower end is provided with a flange or head, 52, through which asetscrew, 53, turns against the spindle 49, and the diameter of the aperture through the arm 17 is somewhat greater than the diameter of the sleeve 50, but less than the diameter of the flange 52. By this construction the spindle or guide 49 may be adjusted vertically in the sleeve 50, and secured in position by the setserew 53, and may be adjusted horizontally in the aperture in the arm 17 and secured in place by the nut 51. It will be un derstood that the function of this guide 49 is to followthe elevations and depressions of a pattern placed immediately under it,whercby the movements of the tool 28 are guided up and down.

In the construction of thejoint between the hinge 12 and the arm 4 a bolt, 54-, is inserted through the hinge 12 into the arm 4, which bolt turns by a screwth read into and through a part of the arm 4, and is further secured in place by ajam-nut, 55, turning thereon. The upper part of the shank of this bolt54 is provided with a beveled shoulder, 56, adapted to receive a corresponding beveled bearing of the hinge 12 thereagainst, and the diameter of the aperture through the remaining portion of the hinge-12 is somewhat larger than the diameter of the shank of the bolt 54, so as to reduce as much as possible the points of bearing, and consequently the friction of the hinge 12 against the bolt 54. A recess, 57, is provided in the surface 11 of the arm 4 for receiving oil for lubricating purposes, and an oil-cup, 58, is secured in the top of the bolt 54, and a duct, 59, leads therefrom through the bolt 54 into the recess 57. The shaft 37 has beveled or conical hearings in the lower end of the bolt 54 at one end, and at the other end in the bolt 60, turning through a part of the arm 4. For greater security the bolt is provided with ajam-nut, 61.

For supporting the material to be carved and the pattern for the work to be done a tilt ing table in duplicate leaves D and D is located in front of the swinging arm 4, and in proper position for the work of the cuttingtool and pattern in connection therewith. The part or leafD of the table is pivoted and supported on the uprights E E, which are parts of the frame E, which frameis supported and movable vertically on the sill F, which sill is supported in position by the legs F F.

For moving the frame E vertically a rotating shaft, G, is secured in its under surface,

which shaft is provided with a sere'w'thread turning in the bracket H, which bracket is rigid to the sill F. The shaft G is also pro vided with a pinion, I, meshing with a pinion, J, fixed on a shaft, K, supported and rotating in a bracket, L, which bracket is fixed to the frame E. The shaft K is provided with a hand-wheel, M, for rotating .it. The frame E is guided in its movements vertically in ways in the guide'frame .N, which guideframe is affixed to the ceiling of the building. The upper leaf or table, D, is supported on and made a part of the lower leaf or table, D, by means of the barsO, O, secured at their respective ends pivotally to the lower and the upper table, I) and D, respectively. The outer ends, P I, of these tables D and D are received between and guidedin their vertical movementsby the uprights of the frame E,aud a set screw, R, passing through aslot in the upright of the frame It, and turning into one of the connecting-bars 0, is adapted to secure the tables D and D in position as desired.

The material orblock S to be carved is placed on the table D, and the pattern T is placed on the table D directly above the block S. This block S and pattern T may be clamped to their respective tables, if desired, for which purpose an ordinary wooden clamp, such as is commonly used by carpenters and manufacthrough. the combined movements permitted by the swinging arm 1 and the thereon-hinged post 13, and that sufficient vertical movement can be obtained in the vertical movement provided for of the arms 16 and 17 on thepost 14.,
