Application October 10, 1941, Serial No. 414,406 14 Claims. (01. sic-13.1)

- turnably mount a gear on one of the arms of the pantograph and to mount a following rod and following pointer in a certain way on and in re.- lation to said gear, to provide a cam to control the separation of said pointer and rod, and a certain mechanism operated by these parts to control a cutting tool.

It is proposed to mount the cutting tool on an arcuate member which is mounted on a barturnably mounted on another one of the arms of the pantograph at a similar point to the point of location of said gear on said pantograph arm. A transmission system is proposed from the firstnamed gear to turn said bar in relationto the turning of the following rod. A mechanism is also proposed for pivotally moving the cutting tool on the arcuate member in relation to the spacing of the following rod and following pointer.

In practising the'invention it is proposed to provide a specially prepared picture which is to be copied in relief. It is proposed that this picture have guiding lines drawn or imprinted thereon in accordance with a certain process to control the relief of the picture. The invention will point out a photographic method of obtaining the copyin picture with the lines. a

For further comprehension of this invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

The cutting and reducing device for relief pictures, in accordance with this invention, includes a pantograph 20 of the usual construction. A gear 2| is turnably mounted on one of the arms of the said pantograph 20. A following rod '22 is coaxially fixedly mounted through the gear 21. This rod projects above and below the gear. A following pointer 23 is mounted upon the top end of the rod 22 and extends through a slot 24 formed in the gear 2|. A wheel 25 is turnably mounted upon the bottom, end ofthe following rod 22 to guide the following rod upon a picture being copied. The following pointer 23 is flexi ble and normally seeks a position so that its bottom end is very close to the following wheel 25.

A cam 26 is movably mounted on the following rod 22 and is adapted to control the separation of the following pointer 23 and the following rod 22.

The cam 26 is provided with a projecting handle 2'! by which it may be conveniently moved.

The arrangement is such that when the handle 21 is moved downwards the cam 26 separates the pointer 23 and rod 24 in direct relation to the distance through which the cam is moved. A cable 28 is connected with the cam 26 for communicating the position of the cam to the cutting tool of the device, as hereinafter more fully explained. One end 28 of the cable 28 is attached to the top of the following rod 22. The cable then extends around a pulley 29 mounted on the side of the cam 26. The cable 28 then extends up over a guide element 38 mounted on the top 7 of the following rod 22 and extends over a guide mounted on the top end of the bar 34, and more particularly, on the pivot of the bar. An endless member 31 connects the gears 2i and 36 for turning the last-mentioned gear the same angular amount as the first mentioned gear isturned. This endless member 31 has a sprocket chain section 31 which engages around the gear 36 and a sprocket chain section 37 which engages around the gear 2 I.

An arcuate member 33 is mounted on the bar 34 and has its center of curvature directly below the bar in the vicinity of the extremity 33 of the cutting tool 33. The cutting tool 33 comprises a small electric motor 33 which is supported by several of the clamps 32 which are slidably mounted in arcuate tracks 43 formed concentric with the point 33'. Each clamp 32 comprises a base section 4| which sli dably engages in a groove 40, and a motor supporting ring 42 mounted on the base section 4|. A cutting implement 44 is mounted on the shaft of the motor 39; i

The cable 23 has its end 28 connected with the central one of the clamps 32. An auxiliary cable 45 connects with this central clamp and extends around the bottom portion of the arcuate member and up along the outer side and connects with one end of a spring 45 which has its other end 46 fastened to the arcuate member. The construction is such that when the cable 28 is pulled the spring 4-8 will stretch and the cutting tool 33 will be moved to a different .arcuate position without disturbing the extreme end 33 of the cutting implement of the tool. The cutting implement 44 is illustrated cutting the work 48 at the area 48 A mechanism is provided for supporting the arcuate member 38 in various elevated positions. This mechanism includes a rack 49 on one side of the arcuate member 38 and disposed within a groove 50 formed in the bar 34. The rack 49 meshes with a gear 5| on a stem 52 rotatively supported in a plate 53 fixedly mounted on the side of the bar 34. The stem 52 extends through a gear 54 which is stationarily fixed on the plate 53 by several rivets 55. A handle 56 is mounted on one end of the stem 52. 'A spring 51 is carried by the handle 58 and engages the teeth of the gear 54. r

The arrangement is such that the handle-53 maybe turnedin one direction or the other to force the spring 51 over the teeth of the stationary gear 54 to turn the stem 52 so as to raise or lower the rack 49 and thus the arcuate member 34.

The apparatus is operated in conjunction with a picture 63 which is to be copied. This picture has certain prepared lines 6| drawn or printed thereon. One method of making a picture of this type is illustrated in Fig. 18. A standard projector 62 is provided with a special screen 63 having a plurality of parallel lines 64. These lines are formed by winding a cord over a plurality of top and bottom pegs 65 mounted on a frame 66 of the screen. The projector 62 has an opening 61 in which the screen 63 is mounted. The projector 62 is thrown upon an object 68 to be photographed and the object 68 will have lines on it produced by the lines 64. The object 68 is photographed with a standard camera 69. The finished picture will look like the picture shown in Fig. 1 and indicated by reference numeral 60.

In Figs. 19 and 20, a screen 13 is shown in a frame 66*; This screen is made of an opaque screen and is formed with vertical slots 'H to permit the rays from the projector to form lines of rays on the object 68, which may be photographed by one or two cameras facing each other in direct alignment, each from the projector 62. With two cameras the linesat both sides of the object may be photographed simultaneously. 1

If it is desired, more than two cameras may be used and the photographs may be taken. at 45 or at any other suitable angle. The lines 6! may also be prepared by drawing the lines on the picture 60.

The device is used as illustrated in Fig. 1. The picture 60 is copied by moving the following wheel 25 and the following pointer 23 along parallel lines SI of the picture [6. This is done by merely holding the handle 21.. The handle 27 must be moved downwards when the lines GI separate, and moved upwards when they come closer together. The handle 21 must be turned to maintain the wheel 25 upon the line being followed when this line turns. 7

All turning movements of the following rod 22 will be communicated by the endless member 3? to correspondingly turn the bar 34. All movements of the pointer 23 towards and away from the'following rod 22 will be communicated by the cable 23 to correspondingly move the cutting 13001.33. It is merely necessary to follow the guidinglines on the picture 63 to produce the work" 48 which will correspond with the picture but be in relief, depending on the guiding of the lines While I haveillustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein. disclosed and the right is reserved to all changes and modifications coming, within the scope of the invention as defined in the appended claims.
