REIPBODU'CING-MACHINE.

Specification of Letters Patent.

Patented Nov. 24, 1914..

Application filed June 27, 1914. Serial No. 847,679.

To all whom it may concern Be it known that I, ADAM Boon, a subject of the King of Bavaria, and a resident of the city of New York, borough of Brooklyn, 1n the county of Kings and State of N ew York, have invented a new and Improved Reproducing-Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved reproducing or copying machine designed for reproducing statuary, relief plates and other works of art, either of the same size as the pattern or of an increased or a diminished size, and withskilled artisan.

In order to produce the desired result, use is made of platforms, one for supporting a pattern and the other for supporting the work, a lever mounted to swing up and down and laterally, holders adjustably mounted on the said lever, one of the holders carrying a tracer for following. the contour of the pattern and the other holder carrying a carving tool for engaging the work, and means for adjusting the said holders on the lever.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specificatiomin which similar characters of reference indicate corresponding partsin all the views.

Figure l is a plan view of the reproducing machine; Fig. Qis a side elevation of the same; Fig. 3 is a cross section of the sameon the line 33 of Fig. 2; and Fig. 4 is an enlarged cross section of the same on the line 414 of Fig. 2.

On a suitably constructed base A is armounted to turn a vertically disposed pin C depending from a bearing O in which is journaled a transversely'disposed pin O forming the fulcrum of a lever D mounted to swing up and down on the said pin O as a fulcrum and capable of swinging laterally owing to the bearing O in which the pin O is journalcd. The lever D is preferably formed of two tubular rods D, D connected with each carrying the pivot pin C the rods D, D beingalso connected with each other at their forward ends by a connecting piece E and at their rear ends by a connecting piece E supporting a weight E to eounterbalancethelever and,

the parts mountedon the front end thereof.

1n the rods D, D telescope rods D, D

connected with each other at their forward 1 ends by a connecting iece D. On the rods D, D of the lever is mounted to slide a holder F carrying a tracer G or a carving tool G connected by a flexible shaft H with a motor for rotatingthe carvingtool G. On the rods D D is mounted to slide a holder I carryinga tracer Gor a carving toolG connected by a flexible shaft H with a motor for rotating the carving tool G. When it is desired to reproduce, for instance, a statue J on a larger scale, then the holder F is provided with a tracerwhilc the holder is provided with a carving tool. When it is desired to reproduce such a statue on a smaller scale, then the tracer is used in the holder I and a carving tool is employed on the holder F.

, In order to support the pattern J and the work J to be reproduced, use is made of platforms K and K arranged on top of supports L and L, mounted to slide on an inclined guide A ttached at one end to the base A and at its other end to a second base A the said bases A and A andthe guidewayA. constituting the framework of the machine. The supports L and L are adapted to be fastened in place by suitable clamping screws N, N engaging a slot A arranged on the guideway A. The platforms K and K are provided with depending shafts K", K journaled in the supports L, L and provided at theirlower ends with bevel gear wheelsK, K in mesh with bevel gear wheels O,O secured on a shaft O journaled in suitable bearings R arranged on the bases A and A, it being understood that the shaft 0 is inclined and parallel to the slot A. The platform K is provided with spanner openings or recesses K to permit the application of a spanner wrench or other tool with a view to allow the operator to turn the platform K whereby a like turning motion is given to the platform K by thegearing described so that the platforms K and K rotate in unison. The shaft 0 is provided witha key-way 0 into which fit keys 0 on the gear wheels O and O to allow adjustmentof the supports L and L toward or from each other without disconnecting the gearings. Y i y In order to obtain the desired between the pattern and the necessary to adjust the holders F and I toward or from each other and relative to the proportion pivot pin C of the lever D. For this purpose the holders F and I are provided with nuts F and it" inwhich screw the threaded work, it is portions P and P of a screw rod P mounted to turn in a bearing E arranged on the connecting piece E previously mentioned. The threaded portions P and P are of a difierent pitch and the screw rod P is provided at one end with a suitable handle P to permit the operator to turn the said screw rod with a view to move the holders F and I toward or from'each other at a different ratio according to the scale on which the work is to be reproduced from the pattern.

When the work J be on a larger scale than the pattern J then the latter is placed on the platform K and the work is placed on the platform K, the said platforms K and K being moved a distance apart according to the relative proportion between the pattern and the work, and in alike manner the holders F and I are spaced apart so that the centers of the tracer G and the carving tool G are in a vertical transverse plane passing through the centers of the platforms K and K. The carving tool G is rotated and the operator having hold of the lever D swings the same up or down and laterally to cause the tracer G to follow the contour of the pattern J thus causing the tool G to carve the work J correspondingly. As the work progressesthe operator turns the screw rod P so as to move the tracer G and the tool G in the proper. proportion in a lengthwise direction according to the thickness of the pattern J and the work J, and the operator periodically turns the platforms K and K so as to cause the carving tool G" to act on the Work on the corresponding parts with a view to completely finish the work according to the pattern.

The reproducing machine shown and described is comparatively simple and durable in construction and can be readily adjusted for reproducing a statue, panel or other work of art on a larger or a smaller scale. For panel work it is not necessary to revolve the platforms K and K as the depth of the work is readily obtained by swinging the lever D laterally.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:
