UNITED STATES PATENT OFFICE.
ALONZO D. SEAMAN, OF MILWAUKEE, WISCONSIN.
CARVlNG-MACHJN E.
SPECEIFICATION forming part of Letters Patent No. 588,662, dated August 24, 1897.
Application filed September 3, 1895. Serial No- 561,28 5. (N0 model.)
To all whom it may concern.-
Be it known that I, ALONZO D. SEAMAN, of Milwaukee, in the county of Milwaukee and State of Wisconsin,have invented certain new and useful Improvements in Carving-Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable othersfskilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
The main objects of my invention are to embodying my improvements, a portion of the frame'being broken away. Fig. 2 is a front elevation; Fig. 3, a rear elevation; Fig. 4:, a plan view; and Fig. 5, a sectional detail, on an enlarged scale, of a portion of the frame.
For doing the finer grades of work with a carving-machine it is essential that the toolcarrier and its guiding connections be as light as possible, so as to avoid gouging the work by the inertia of the moving parts, that the tools be rigidly held in the proper relations to each other and to the work, so as to insure uniform and accurate work,and that the work and pattern be firmly held in place while being operated upon by the tools.
Referring to the drawings, the frame for convenience andeconomy is preferably made of two cast-iron side sections A A, which are formed at the top with horizontal ways a a, upon which is mounted so as to slide freely forward and backward the work-supporting bed or table 13. The side sections of the frame are rigidly connected with each other by tubular cross-pieces a a, which are let at the ends into countersunk holes in said side sections parallel with the cross-rod F.
and secured therein by tie-bolts a ,threaded at the ends and provided with nuts (1 as shown in Fig. 5. By this means the side sections are firmly andrigidly bound together, and a light, strong, and cheap frame is produced.
0 is a tool-carrier consisting of a light open metallic frame formed or provided with a holder 0 for a tracing-tool D and with handpieces and bearings c c for rotary cuttingtool spindles E E, which are furnished in the opening of the frame or carrier with grooved pulleys e e.
F is a cross-rod formed or provided at the ends with depending arms f f, to which the ends of the tool-carrier are pivoted in a line parallel with said cross-rod,as shown in Fig. 2.
Between two standards G G, rising on opposite sides of the frame, is pivoted in a line parallel with the cross-rod F an open frame or yoke H, as shown in Fig. 3. In thisyoke are journaled vertical shafts,on each of which is mounted a larger and a smaller pulley h and h, respectively. The cross-rod F, from which the tool-carrier O is suspended, is connected with the pulley-yoke H by horizontally-disposed jointed arms J, each composed of two members j and j, forked at'the ends and pivoted to each other and to the crossrod F and yoke H in parallel vertical lines. The rear ends of the membersj are pivoted to the yokeH concen trically with the pulleys h h. Concentric with the pivot connections between the two members of each arm are jouraled therein a pair of pulleys k and Zn. The front ends of the members j are bent ortur-ned upwardly, so as to bring the pulleys 6 con the cutting-tool spindles in line with the pulleys k k, with which they are connected by belts,
as shown in Figs. 1 and 4. The pulleys k are connected by belts with the pulleys h, and the pulleys h are connected with drivingpulleys. (Not shown.)
L is a rock-shaft supported by the upper forwardly-projecting ends of standardsG G, It is provided with two forwardly-projecting arms Z Z, which are connected bydepending rods Z Z with the cross-rod F. The rods Z Z have universaljoint connections Z Z with the arms ZZ and the cross-rod F, and with said arms and the rock-shaft L constitute an equalizer by which both ends of the tool-carrier are caused to rise and descend exactly together, thus admitting of the employment of much lighter horizontal guiding connections between the tool-carrier and the main frame.
The arms J J are connected by a cross-rod 9' by which they are held parallel to each other. This rod is shown as pivoted to rearward extensions j of the members j of said arms, but it may be pivoted directly to the members of said arms in front of the yoke II.
The standards G G, with which the toolcarrier is connected by the guiding mechanism above described, are connected and rigidly held in place by a tubular cross-piece a and a tie-bolt (1 like those hereinbefore described, and by a cross-bar g, as shown in Fig. 3. The cross-bar g is formed with a yoke g, having a vertical slot or opening through which an arm 71, projects rearwardly from the yoke II. In the lower part of the yoke g is fulcrumed at its front end a lever M, provided with an adjustable weight m, and in the upper end of said yoke is fulcrumed at or near the middle a lever N, provided at the front end with an adjustable weight n and connected at its rear end by a chain or cord with the rear end of the arm 7L connected between its fulcrum and weight with said arm h and acts thereon in opposition to the lever N.
By the provision and arrangement above described of two counterweights acting in opposition to each other a more sensitive and steady movement of the tool-carrier is secured than could be accomplished with a single weight.
The several pulleys through which power is communicated to the cutting-tool spindles being centered in the axial lines on which the tool-carrier G, the yoke H, and the members of guiding-arms J swing, the driving connections of the cutting-tools do not interfere with the free movement of their supporting and guiding connections.
The operation of the machine will be readily understood by those skilled in the art to which my invention pertains from the foregoing description of its construction. Although the movable supporting and guiding connections of the tools are comparatively light, they are sufficient to hold them rigidly in their proper relation to the work-table, so that any movement of the tracing-tool will be exactly followed by the cuttingtools, and they are adapted to do the heaviest kinds of roughingwork, as well as the lightest and most delicate carving.
I claim- 1. In a carving-machine the combination with a suitable frame provided with a worksupporting bed or table, of a tool-carrier provided with a tracing and one or more rotary cutting-tool holders, horizontally-disposed parallel jointed arms connecting said toolcarrier with the frame, and an equalizer con- The lever M is in like manner 7 sisting of a rock-shaft supported in said frame above and parallel with said tool-carrier and provided with arms which are connected by rods with said carrier at or near its ends, substantially as and for the purposes set forth.

3. In a carving-machine the combination with a suitable frame provided with a worksupporting bed or table, of a tool-carrier provided with a tracing-tool and one or more rotary cutting-tool holders and spindles each provided with a pulley, a cross-rod having depending arms to which said carrier is pivoted in a line parallel with said rod and passing approximately through the center of the pulley on each cutting-tool spindle, a yoke pivoted at the ends to said frame in a line parallel with said cross-rod, horizontally-disposed parallel arms, each composed of two parts pivoted to each other and forked at the ends, which are pivoted to said carrier and yoke respectively, the front ends being upwardly bent or offset, and horizontally-disposed pulleys journaled in pairs in line with the middle and rear pivot connections of one or more of said arms, and connected with each other and with a drivingpulley and the pulley or pulleys on the cutting-tool spindles, substantially as and for the purposes set forth.
