CARVlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 394,710, dated December 18, 1888.

Application filed June 18,1888- Serial No. 277,405. (No model.)

To all whom it may concern:

Be it known that I, STEPHEN F. MOORE, of Milwaukee, in the county of Milwaukee and State of lViseonsin, have invented new and useful Improvements in Carving-Machines; and Ido hereby declare the following to be a full, clear, and exact description of said invention, reference being bad 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 improvements in the carving-machine for which I filed an application for Letters Patent on January 7, 1888, which application is Serial No. 260,005, and inheres in the form and construction of the various parts of the mechanism and in the location, combination, and arrangement of those parts in the complete device, substantially in the manner and for the purposes hereinafter described.

In the drawings, Figure l is a side elevation of my complete device in its improved form,havingamodified material and pattern holding mechanism for operating on curved material. Fig. 2 is a plan from above of the tool-holding portion of my device, taken on line X X of Fig. i. Fig. 3 is an elevation of a portion of the swinging arm and the theretopivoted standard and the band-wheel and pulley supported on the arm, partly in section to show form of construction. Fig. at is a plan of a portion of the upper or gufile-carrying arm of the tool and guide carrying frame. Fig. 5 is the enlarged part of the upper inner end of the swinging arm, showing its attachment and method of adjustment on its supporting-hinge. Fig. ii is a central. horizontal longitudinal section through the lower inner endot' the swinging arm and its su )portinghinge. Fig.7 is an elevation of illOOOlllltCl'POlSQ of the tool-carrying frame and of the standard in which its supporting-lever is pivoted. Fig. 8 is an inside elevation of the material and pattern supporting frame. Fig. 9 is a vertical transverse section of the material and pattern supporting frame on line Y Y of Fig. 8.

Fig. 10 is an elevation of the rear or inner side of one of the swinging tables shown in Fig. 8.

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

,For conveniently supporting the tool-carrying mechanism a post or base piece, A, is

securely affixed to the side of the building B. Brackets C and D are removably affixed to the post A, and a vertical shaft, 1, is supported and has its hearings in the brackets C andD. Shaft 1, at its lower end, has a conical bearing in the bracket at E, and passes through and has a bearing in another short arm of the same bracket at F, and has still another bearing in a jonrmtl-block, G, supported pivotally in the outer end of thebraeket I). This arrangement of the bearings of the shaft 1 is provided to secure a proper alignment and the least amount of friction with proper support. Near its upper extremity this shaft 1 carries a fixed driving-pulley, H, and a loose bandpulley, l, on which pulleys the driving-belt K runs. A liorizontally-swinging arm, 2, provided with hinges 3 and t, to which it is adjustably secured, is by the hinge 3 pivoted on the bracket above the shaft l, and by the hinge -t is pivoted in the bracket below the shaft 1, but in the line of the axis of the shaft 1.

The hinge l is provided with an enlarged vertical face having a recess, (seen in Fig. (3,) in which a pin or arbor, 5, integral with the arm 2, enters and acts as a pivot about which a slightly oscillatory movement of the arm :2 may be had for the purpose of adjustment. The arm 2 is also provided with an enlarged end and face adapted to bear against the enlarged face of the hinge 4-, through which enlargwl part of the arm 2 are two curved slots, as shown in Fig. 5, which slots are adapted to receive the set-screws (5 ti, which set-screws turn into the hinge 4t, and are adapted to secure the arm firmly to the hinge, while providing for the adjustment of the arm 2 on the hinge r. The hinge is also provided with an enlarged part having a face adapted to receive thercagainst a corresponding face of an enlarged part of the arm 2, and this enlarged part of the arm 2 is provided with laterally-extendin g slots, through which pass the set-screws 7 7, which turn into the enlarged part of the hinge 3, as seen in Fig. 2, thereby providing for the slight oscillatory or adjusting movement of the arm 2, also provided for in the connection made by the arm 2 with the hinge l. This construction and connection of the arm 2 with its hinges 3 and 4 are adapted to provide for a Vertical alignment of the arm 2 or for a slight tilting of the arm, if desired, for the purpose of obtaining some particular result with the cutting-tool. The hinge 4 has pointed or conical bearings in the lower part of the bracket 0. To the outer bifurcate end of the arm 2 is pivoted or hinged a standard, 8.

To secure the least possible friction and a close adjustment of the parts, together with the greatest wearing strength, the standard Sis pivoted onto arm 2 by means of steelhardened pins, preferably constructed as shown in Fig. 3. A pin, 9, having an enlarged head is inserted vertically in a raperture therefor in the outer end of the lower bifurcate part of the arm 2, which pin 9 has a com-- cal recess in its top adapted to receive and support the conical end of pin '10, which inserted in an aperture therefor in the standard 8, and has a collar, 11, integral there with, on which the standard 8 bears and is supported. The pin 12, having an enlarged top, is inserted in an aperture therefor in the upper part of, the standard 8, and a pin, 13, is inserted in the upper bifurcate part of the arm 2, and terminates at its lower end in a conical point fitting into a corresponding recess in the pin 12. All these pins, 9, 10, 12, and 13, are secured adjustably in their respective bearings by set-screws 14 14 turning against them. A lower tool-carrying arm, 15, and an upper guide-carrying arm, 16, connected together by the rods 17 17, forming a tool and guide carrying frame, are supported and have a vertical movement on the stand-, ard 8.

The arm 15 is provided with two inwardlyprojecting pins, 18 18, inserted movably in apertures therefor opposite to each other in the bifurcate end of the arm 15, which pins 18 18 are diamond-pointed and enter and fit into vertical grooves therefor in the standard 8, as ,shown in Fig. 2. The upper arm, 16, is provided with two sets of diamond-pointed steel pins, 19 19 and 19 19, opposite each other in pairs in apertures therefor in the bi furcate end of the arm 16, which pins have their bearings in corresponding V- shaped vertical grooves in the standard 8. All these pins, 18 18, 19 19, and 19 19, are provided with re-enforcin g screws 20, for foreing them forward endwise to take up wear, and also with set-screws 21 21.,to secure them firmly in position when adj usted by the screws 20 20. By means of this double set of ways and pins 19 19 19 19 a correct and reliable vertical movement of the tool and guide carrying frame is secured with the minimum amount of friction. To limit the vertical movement of this frame two stops, 22 22, pro vided with vertical slots, are secured ad justably to the standard 8 by set-screws23 23, passing through the slots and turning into the standard. This tool and guide carrying frame is supported and counterpoised by means of the oscillating lever 24, pivoted in the upper end of the upright 25, which upright is integral with standard 8, one arm of which lever 24 is connected to the tool and guide carthe'arm 15.

guide carrying frame by rod 26, all have fixed positions relative to each other so far as a horizontal motion is concerned, so that the horizontal swinging of the arms 15 and 16 carries with them the lever 24, and no change of po sition or twisting relative to each other ocours as would occur if the lever 24 were pivoted on some bracket fixed to the immovable post A or to the building. In the free outer end of arm 16 an adjustable guide, 29, is car-, ried, which is made adjustable in the arm 16 by means of an adjustable sleeve 30, as fully described and claimed in my previous application hereinbefore referred to. Th e free outer end of the arm 15 is expanded into a globe-like bracket, 31, and therein is supported and carried the spindle which carries the cutting-tool A fixed bandavheel, 33, on. shaft 1 'carries a belt, 34, which runs on a band-wheel, 35, integral with the pulley 36, which carries the belt 37, running on a pulley onthe toolcarryin g spindle within the bracket 31'.-

A belt guiding and tightening pulley, 38, is supported on an arbor adjustable in a slot in The band-wheel 35 and integral pulley 36 are supported and have their bearings on conical-pointed steel pins in the lower part of the bracket 2, the axis of which wheel and pulley is in a line with the axis of the standard 8. The steel pins 13 and 63' are screi threaded and turn into apertures therefor in the arm 2, and are each provided with jam-nuts 64 64 and 65 65 at their upper andlower ends, respectively, which are adapted to be turned down on the pin against the suprial and pattern, respectively, within the are made by the swinging arms 15 and 16, is the vertical moving and adjustable frame 39, supported on the frame-work40 rigid to the post, A. This bracket 40 is secured against any lateral or swinging movement by the stayrods 41 41, secured thereto and to the-adjoining wall. The frame 39 is adjusted up and down by means of the hand-wheel and gearing at 42, secured thereto, turning a wormscrew, 43, which turns through a bracket, 44, rigid on the bracket-frame 40, in practically the same way as described in my previous application. The upper part of the frame 39 is guided in its vertical movements by the ways 45 45, rigid to the walls of the room. The

frame 39 is provided with an interior panel,

are each provided at their rear edge with a fixed upright, 49, through and by which one table is suspended above the other, the pivotal points being in the same vertical line, by bolts 50, passing through the uprights 49 49 and through the wall 46, on which bolts the tables 47 and 48, respectively, have corresponding lateral oscillation. These tables 47 and 48 are each secured against vibration with reference to its upright by means of the brace-bars 51 51, which brace-bars are made rigid at their respective ends to the table and to the upright.

The wall 46 is preferably constructed in sections, the surfaces of which are in different planes, as shown in 8 and 9, the division-line between which sections is at the step or shoulder 52 52, and the tables 47 and 48 are each suspended on and against a separate section, whereby the upright and braces of the table 48, being on a deeper or inner sec tion, are carried under or behind the table 47, thus providing for the proper location and oscillation of the tables with reference to their arcs and-required nearness to each other.

The extent of the oscillation of the tables 47 and 48 is limited by the walls or shoulders 52 and 53. These tables 47 and 48, in their rear edges, are each provided with a series of apertures, 54, which series of apertures in location and distance apart correspond exactly with each other. Corresponding pins, 55 55, supported and movable endwise in bushings 56 56 in the wall 40, are adapted to enter the apertures 54, whereby the tables may be adjusted either to the right or left and held in corresponding position by the pins 55 being inserted in corresponding apertures in the two tables. The inner or concave surfaces-of these two tables have the same are, and the upper one is adapt-ed to hold the pattern and the lower one the material for being carved, and are for use when carving is to be produced on curved material-snch as the top cross-bar of bent-back chairs. To secure the pattern and the material to be carved upon the tables, several series of apertures, 57 57, are made through the tables, through which are inserted sets of iron clamps 58 58, provided with hand-nuts 59, turning on the screwthreaded shanks thereof and bearing on the outside against the outer surface of the tables.

It will be understood that the upper table, 47, is located and adapted for holding the pattern against which the guide 29 is adapted to bear, and that the table 48 is located and adapted to receive the material to be cut by the tool 32. A shifting-rod, (50, supported and having vertical movement in brackets on the post A, and provided with a finger, 61, is adapted by means of the lever 62, pivoted on frame 40, to shift the belt K back and forth on the fixed and loose pulleys H and I.

' A slot, 66, is provided in the upright 49 of the table 48, through which the pin 55 passes that enters the upper table, 47, which slot is constructed to permit of the required oscillation of the table 48.

WVhat I claim as new, and desire to secure by Letters Patent, is

1. In a carving-machine, a swinging arm 2, pivoted at two points at a distance apart in the same vertical line, in combination with two hinges, 3 and 4, to one of which hinges the arm is secured by set-screws passing through curved slots in the arm and turning into the hinge, permitting slight oscillation about the horizontal axis of the arm, and to the other of which hinges the arm is secured by setscrews passing through curved laterally-extending slots and turning into the hinge, whereby short segmental motion and adjustment are provided for, substantially as described.

2. In a carving-machinc, a swinging standard, 8, in con'ibination with a tool and guide carrying frame supported and having vertical movement on the standard, such frame being provided with two sets of bearings, 19 19 and 19 19, and the standard 8 being provided with two sets of corresponding ways, in which the bearings l9 l9 and 19 19' are adapted to travel, substantially as and for the purpose described.

Ina carving-machine, a pair of curved tables for holding the pattern and material to be carved, respectively, suspended one above the other and oscillating laterally in the same or parallel vertical planes in arcs parallel with each other, in combination with a vertically or nearly vertically moving cutting-tool and guide-carrying frame, substantially as described.

4. In a carving-machine, a pair of curved tables for supporting the pattern and the material to be carved, respectively, suspended one above the other and adapted to swing in parallel arcs, and provided with corresponding apertures, 54 54, in combination with a supporting-wall, 46, and retaining-pins 55 55, substantially as described.

5. In a carving-machine, amaterial-holding table having a concave surface on which the material rests, which table is so suspended as to swing in the are of its curved surface, and which table is provided with a series of apertures, 57 57, and with clamps 58 58, substantially as described.

6. In a carving-machine, a vertically-movin g frame, 39, and a wall or panel, 46, therein, the surface of which panel is in sections in different planes separated by steps or shoulders, in combination with oscillating tables, each of which tables is suspended on an individual and distinct section and plane of the panel, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
