v Specification of Letters Patent.

Patented Aug. 4, '198..

Application filed September 21, 1907. Serial No. 393,979.

To all whom it may concern:

Be it known that. I, WILLIAM F. MANGELS, a citizen of the United States, and a resident of the city of New York, (Coney Island, boroueh of Brooklyn,) in the county of Kings an( State of New York, have invented a new and Improved Carving-Machine, of which the following is a full, clear, and exact descri tion.

T ie object of the invention is to provide a new and im roved carving machine, for ac? curately am f uickly reproducing in wood or other l'nateriais a plurality of parts simultaneously, according to a pattern.

The invention consists of-novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention `is represented in the accompanying drawings forming apart of this specification, 1n which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the improvement; Fig. 2 is a side elevation of the same; Fie'. 3 is an end view of the same; Fig. 4 is an enlarged sectional plan view of the gearing for rotating the pattern or a work support; Fig. 5 is a transverse section of the same; Fig. 6 is an enlarged sectional plan view of the coupling for throwing the gearing for a. support in or out; Figf7 1s a transverse section of the shifting mechanism for shifting the shaft of the counterbalancing levers in a transverse direct-ion, and Fig. 8 is an end elevation of the improvement arranged for panel work.

The bed A on which the `:iat-.bine is mounted is provided with suita ble legs B, and on the top of the bed A is arranged a revoluble support C for supporting a pattern D, and on the top of the said bed A are arranged a plurality of rcvoluhle supports C', each earrying a. block E of wood or other material to be carved correspondingly to the configuration of the pattern D.

A tracer F under the control of the operator follows the configuration of the pattern D, and carving tools G in the form of revoluble cutters are adapted to cut the blocks E to reproduce the pattern D, as hereinafter more full described. The tracer I" is removably lield in a holder H, and the carving tools G are removably attached to the shafts I', of electric or other rotary motors I, for

rotating the .carving tools G at a high rate of speed. The holder H is ivotedat II in the forked end J of a shaft and the motors I are hung on pivots I2 held in rings J 2 formed on the shaft J, as plainly indicated in the drawings, the pivots H and I2 standing at right angles to the axis of the shaft J. The tracer holder Hand the motors I are provided With extended arms H, I3 pivotally connected with each other by a link K, so that when the operator having hold of the holder I-I imparts a swinging motion to the holder, then a like swinging motion is simultaneously given to the several motors I.

The shaft J extends longitudinally and is journaled in the upper end of a frame L, provided at its lower end with a foot piece or edal L', under the control of the operntors oot. The frame L is pivoted at its ends at Lz on levers N, havlng eounterbalaneing weights N', and secured on a shaft or a pivot N2, journaled in bearings N3, mounted to slide transversely in guideways B', formed on the legs B supportingvthe bed A. In the bearings i 3 screw transversely ext-ending screw rods O, mounted to turn in suitable bearings arranged on the legs B, the reali ends ofP the screw rods O being provided with bevel gear wheels O in mesh with bevel gear wheels O2 secured on a longitudinally extending shaft O3 journaled in suitable bear- -ings arranged on the legs B (see Fig. l). On

the shaft Oq is secured another bevel ear wheel O4 in mesh with a bevel gear wheel O"s secured on a transversely extending shaft O provided at its front end with a hand wheel O7 under the Acontrol of the operator, for turning the shaft O so as to rotate the shaft O3 in either a forward or reverse direction, according to the direction in which 'che hand wheel O7 is turned. The rotary motion of the. shaft O`is transmitted by the gear'- wheels O2, O to the screw rods O, so that the bearings N3 are shifted transversely.whereby the shaft or pivot N2 is carried in a like direction, thus moving the counter-balancing levers N and the frame L with the parts supported thereon, bodilyin a transverse direction. Thus by thev arrangement described, the frame L moving with the levers N can be shifted towards or from the blocks E and the pattern D, and an up and down movement can be given to the frame L, and at the same time a roe-king movement., and in addition the tracer holder II as well as the motors I lio can be rocked on their own pivots held on' v the shaft J, which can also lbe rocked 1n its bearings inthe frame L. Thus by the arrangement described, movement in any delsired direction can be lgwen to the tracer F and the carving tools G, by the operator main the forni of a bar C2 fixed on the support,

and aslidable clamping bar P ad'usta een the support by a set screw P (see lgs. 1 and 5), and betweenwhich bars C2 and P the base. of the pattern D or the base of the work E is clamped. The bar P is guided by bolts l engaging elongated slots C3 in the sup ort C or C'. Each support C or C is secure( on the upper end of a vertically disposed shaft Q journaled in suitable bearingsin the bed frame A (see Fig. and on each shaft Q is lsecured a. worm w ieel Q in mesh with a worm Q2 normally cou )led by a hand coupling or clutch Q3 (see l* ig. 6) with a longitudinally extending shaft Q4 journaled on the bed A. The left hand end of the shaft Q4 is provided with a combination hand and gear wheel Q5, under the control of the o erator,

"for turnino the shaft Q*, which by t e gearing described, rotates the several shafts Q and the supports C, C in unison. "Any one of the supports C or C can be temporarily cutout at any time by the operator shifting the coupling or clutch Q3 out of engagement with the worm Q2, to stop rotation of this particular support. It will be understood that the operator retains his hold on the clutch to kee it out of engagement.

The shaft may be rotated from a motor lt mounted on the bed A and carrying on its shaft R' a pinion R2 in mesh with an intermediate gear wheel R slidable on a stud R* attached to the left hand end of the bed A. The gear wheel lts is ada. )ted to mesh with the combination hand an gear wheel Q", so that when the motor R is running a rotary motion is transmitted to the hand wheel Qi', thus rotating the shaft Q and the suppo'sts C, C', as above described. The gear wheel R can be shifted on its stud lt, to move the gear wheel R3 out of mesh m'th the combination hand and gear wheel Q5.

An electric switch S for controlling the motors l and lt, is )referably mounted on the left hand end of tlle bed A, to be within convenient reach of the operator standing at this end of the machine and having hold of the tracer holder ll, for guiding the tracer -F over the pattern D.

The operation is as follows: `When the several parts are in the position illustrated in the drawings and the motors I are running, then the operator takes hold of the holder H and moves the pointed head of the tracer toward the pattern D, so that the revolving carving tools G come in contact with and 4cut the blocks E, the tools G used lbeing roughenimr tools, to give an outline shape'to the block. according to the pattern D.

lt is understood that the operator ,onimanipuiating the holder H 'can readily bring the 'tracer F into any desired position relative to the pattern D, so that the carving tools G are" moved into a position most effective for do;- ing the desired carving or cutting on the blocks E. After the blocks E are cut down,

.suitable finer tools G are used to allow of accurately carving the blocks according to the pattern, 1t being understood that as the tracer l*` can be moved mtoany desired position by the operator and the tools G assume wheel O7, theentire cutting device and tracer holder are shifted bodily toward or from the pattern or work, as is found most advantageous by the operator.

When doing panel or similar work, as shown in Fig. 8, the turning mechanism for the platform can be dispensedwith.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
