Application filed April 524, 1884. (No model.)

o. e 1s a specication.

My invention relates to an apparatus for tinting and shading the background and other portions ofa drawing or picture made by hand, which tinting or shading is aecomplished by placing the i'ace of the picture in contact with a plate provided with parallel raised lines having printing-ink thereon, and then applying friction or pressure to the back of the picture so. as to obtain an impression from the plate on certain desired portions of the face of the picture.

The invention consists in a novel construction, arrangement, and combination of a base or bed plate, a plate for carrying the tint-plate, a plate for holding the picture, and certain details of devices for adjusting and changing the position of the tint-plate, and for other purposes, as hereinafter more particularly described.

In the accompanying drawings, which forni a part of this speciiication, Figure l is a top view of an apparatus embodying niyimprovements. Fig. 2 is a section taken in the line x a' of Fig. l. Fig. 3 is ascction takenin the line y y of Fig. 1. Fig. 4 is a top view of the base or bed plate. Fig. 5 is a sectional view ol' the saine. Figs. (i, 7, 8, 9, 10, 1l, l2 are views of anioditication. Fig. 11.3 is a top view ol" a portion ot' the apparatus. Fig. 14 is a side view ot' the saine. Figs. 15 to 25, inclusive, are detail views of different parts of the apparatus. Fig. 26 is a perspective view of the machine.

The base or bed plate A is of an approximate quadrangular forni, (see Fig. 4,) and is provided on its under side with ribs or feet a, on which it rests. On the upper side,near the four angles, are cavities afor the purpose hereinafter described. In the center of the plate is an upwardly-extending hollow boss or shortsleeve,a ,whieh receives a downwardlyextending pivot, bx, in the center of a circular plate, B, which is provided with feet b, resting on the base or bed plate A. The plate D is also provided. with two radial slots, b2,

extending in two opposite directions from the center. These slots receive two radial ribs or fins, c2, extending downward from the under side of another circular plate, 0 resting on the plate B. At the edge of the plate C is a downwardly-extending lug, c, through which a thumb-screw, D, passes and engages with a tap-hole in one of the feet b of the plate B. A spring, d, surrounds the screw D between the lug o and the foot b. The width of the slots b2 corresponds with the thickness of the ribs or ns c'so as to prevent any lateral motion of the, plate C on the plate B; but said slots, are longer than said ribs or fins, and thus admit of a radial motion with relation to said slots; and the lug c, the screw D, and the foot b with which the screw engages are in the saine radial line with said slots, by which means such radial motion is obtained, when desired, by turning the, screw in one direction or the other. The head of the screw D, thus arranged, also serves as a knob or handle, to be used when it is desired to rotate the plates B C on the pivot bx as a center, for the purpose hereinafter described.

E represents a skeleton plate or frame, the inner edge of which forms a circle corresponding in size with the periphery ofthe plate C, so as to t around the same. Outside of this circle are four feet, f, at points corresponding with the positions of the cavities a2 in the base-plate A, so that said feet rest in said cavitiis when the apparatus is in position for use. These feet are formed by screws passing through tap-holes in lugs e, formed outside oli' the circle in the plate or frame E. rFhe points or lower ends of the feetf are rounded to correspond with the cavities a2, so as to fit snugly therein, and as the feet are screw-threaded they may be adjusted with exact nicety, and the plate or frame E may be raised or lowered when desired.

G represents a ring,which rests upon the upper surface of the plate or frame E, its inner circle corresponding with that of said plate. In this ring are four holes, g, corresponding in position with four tap-holes in the plate or frame E.

H H represent two bars, each having holes near the ends. These bars are placed over the ring G, so that the holes in each bar correspond Vwith two of the holes in the ring and IOO the plate. Thumb-screws J are then passed through the holes in the bar and the ring and engaged Withthe tap-holes in the plate, and thus is formed a clamping device for holding the picture in place, as hcreinafterdescribed.

The tint-plate consists of a metallic plate, K. on the upper surface of which are parallel lines formed by ridges with intermediate grooves. The tint-plate may be circular in form, and corresponding in size with the plate G, or it may be square, as shown vin Fig. 6. When it is circular, it is held in place on the plate C by clamps consisting of small plates Z, secured to the edges of the plate C by screws and having overhanging lips or hooks engaging with the edges of the tint-plate. When the tint-plate. is square or smaller than the carrying-plate C,it is held in place by clamps consist-ing of slotted plates m, secured to the carrying-plate C by screws, as shown in Figs. 6, 8, and 17.

The various parts being in the position shown in Figs. l, 2, and 3, and the tint-plate being supplied with ink,the apparatusis ready for use. rlhe picture to be tinted is first drawn in outline, and is mounted on a stretcher-frame, P, of sufficient size to allow its corners to rest on the ring G. The bars H are then screwed down by means of the thumb-screws J, so as.

to clamp the frame P securely in place. The ring G is sufficiently thicker than the tintplate to prevent the picture from coming in actual contact with the tint-plate, and to allow the tint-plate to be rotated without touching the surface of the picture. When pressureor friction is applied to the back of the picture by means of a pad, stylus, or other suitable instrument, the face of the picture is brought in contact with the tint-plate, and an impression is obtained therefrom on the face of the picture at points corresponding with those at which the pressure is applied on the back, and at such points only, by which means the picture is easily and rapidly tinted and shaded in any desired portion, and the lines maybe made to run in any desired direction. If horizontal lines are desired, the tint-plate is arranged with relation to the picture, as shown in Fig. 1. If vertical lines or any intermediate angles are desired, the tint-plate is readily placed in the required position by rotating the carrying-plate on the pivot bx as a center, as above described.

If the lines are not near enough together, or if they are not heavy enough, by turning the screw D the carrying-plate C is moved in such a direction as to obtain an impression of lines intermediate between those already printed, or so close to said lines as to make them wider or heavier, and by means of the screw and spring the adjustment of the plate may be made with exact nicety.

If the tint-plate should not be of the proper thickness with relation to the thickness of the ring G, the proper adjustment of the picture with relation to the tint-plate maybe obtained by means of the screw-feet f.

Referring to Figs. 1, 2, 24, and 25, Q represents a rod, carrying at one end a pencil, R, and having its other end passing through a post, S, provided with a set-screw. The post S is adapted to engage with holest in the ring G. By means of the set-screw the rod may be held in place with the pencil at any desired distance from the post. The obj ect of this instrument is V.to enable the operator to determine the proper position of the picture with relation to the tint-plate. For example, the

objective point on the picture having been obtained, the rod Q is -adjusted sov that the pencilA R will correspond with said point. The rod Q is then swung around out of the way, the piet-ure removed, the rod and pencil again brought to their former position, and the tintplate is adjusted by means of the screw D until a certain line or point on the tint-plate is brought to a position corresponding with that previously indicated on the picture.

It is obvious that the operation thus described may be reversed--that is to say, the objective point may be rst ascertained on the tint-plate and the picture afterward adjusted to correspond therewith. Vhen it becomes necessary to remove a picture before completion, with a view to replacing it afterward in order to complete it, a Vcertain point or points may be indicated by the pencil on the back of the picture before removal.' Then, when the picture is replaced in order to complete it, the position formerly'occupied by it maybe resumed without difficulty by adj usting it so that the points formerly indicated will correspond with those called for by the pencil.

I do not confine myself to the particular construction and arrangement herein shown and described, as the different parts of the apparatus may be modified in various ways in order to produce similar results.

The picture to be operated on is gummed or otherwise secured to the stretcher-frame P, which holds it parallel with and a short distance from the front face of the tint-plate K, from which the impression is to be taken. The said stretcher-frame rests on the annular plate E, which is xed to or rests permanently on the stationary bed-plate A. The tint-plate K is mounted on the turn-table B C, on and with which it may be rotated, and also be laterally adjusted by'mea-ns of the sliding top plate, C, as above described.

The shading on the picture is made by pressing the paper or cloth of the picture down upon the tint-plate, as above described. By sliding or rotating the said tint-plate by and with the said turn-table plate, as above mentioned,
