GLOSSlNG-MACHINE.

SPECIFICATION forming part of Letters Fatent N0. 247,745, dated October 4, 1881.

I Application filed July 21, 1881. (No model) To all whom it may concern:

Be itknown that we, OYRUs CHAMBER-S, J r., and S. BERNARD CHAMBERS, of Philadelphia, in the county of Philadelphia and State of 5 Pennsylvania, have invented certain new and useful Improvements in Glossing-Machines; and we do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin g drawings, and to letters ofreference marked thereon, which form a part of this specification. Figure l is a perspective view of our improved machine. Fig. 2 is an end view. Fig. 3 is a side elevation. Fig. 4 is a plan view. Figs. 5, 6,7,8, and 9 are details on an enlarged scale.

The same letter indicates the same part wherever it occurs in the drawings.

Our improvements relate to a machine for sizing and varnishing paper, patented by Richard McNamee August 1, 1877, No. 194,453, and reissued to Allen, Lane, and Scott, as assignees of said McNamee, September 10, 1878, No.

Our improvements consist, first, in substituting for the conveyor-tapes a broad apron which carries the sheet to be varnished; sec

0nd, in devices for tripping the varnish-fountain at the will of the attendant, for purpose hereinafter stated; third, making the roller over which the apron runs serve as a main shaft from and by which poweris communicated to the other parts of the machine; fourth, giving a positive motion to the apron by means of sprocket-wheels working into a safety-chain to which the edges of the apron are attached; 40 fifth, hanging the swinging frame on journals concentric with the roller which carries the apron; sixth, preventing the apron from running crooked or gathering up in the middle of the rollers by attaching it to chains driven by sprocket-wheels which hold the chains apart,

all as hereinafter more specifically set forth.

In the drawings, A marks the frame of the machine, in which the operative parts are supported and work. Y

cylinder F when the table is raised. Gage- 6o fingers e on the same shaft are lowered by the same movement to allow the sheets to pass in. The fountain G, which carries the varnish, rests upon the arms I, projectingfrom the rockshaft J, to which is also attached the lever K projecting downward and operated by the treadle L. The shaft L of treadle L is fiat on one side and convex on the other, and acts as a cam to give a slight movement to lever K (shown by dotted lines in Fig. 3) to throw the fountain and its varnish-roller into or out of contact with the surface of the main drum F.

The fountain G is provided with a composition varnish-roller, H, turning in the varnish in the reverse direction from the drum F, being geared to it by the long-toothed wheels '0 w. A doctor-roll, w, in the fountain (see Figs.- 6 and 7) regulates the amount of varnish the roller H is to receive and apply to the paper. This doctor-roll moves slower than the roller H, receiving its motion from it by gear o w, Fig. 1, and is adjustable by means of sliding boxes G, Figs. 6 and 7. An agitator or stirrer, y, is placed in the fountain to stir the varnish. It is operated by the gears 10 to, Figs. 8 5 6 and 7.

A stationary bar, 00, Figs. 6 and 7, carrying a series of small rollers, 00, is attached outside of the fountain at its inner edge, and serves to prevent the backs of the sheets or boards 0 from dragging on the edge of the fountain when it leaves the feed-board.

The fountain is adjusted in its distance from drum F by means of bolts and set-screws in the grooves of brackets I, Fig. 1.

When the treadle-cam is in the position shown in full lines in Fig. 3, the fountain G is held up and the composition-roller H comes in contact with the packing on drum F; but when it is desired to mix the varnish, reduce it with oil or spirits, or to run the machine without varnishing, the treadle is reversed to the position shown in dotted lines, and the flat side of the cam brought to the lever, which allows the fountain to fall a short distance, not far enough to throw the long toothed wheels out of gear, but far enough to allow roller H to clear the packing and allow the machine to rnnidlewithoutdamagingthepacking. Should the feeder desire to adjust the bank of paper, or should heinadvertcntly miss feeding a sheet, he can instantly throw down the fountain witlr out stopping the machine, and raise it again when ready by the operation of the treadle.

The cylinder F has a blanket, F, composed of a pile of thin paper or felt, (see Fig. 5,) whichis nailed to the cylinder at one end, and clamped over the edge of the lagging at the other end (where the gripers take the paper or card-board) by an iron plate, F, on the bar Z, on which is a lever, Z, outside the cylinderhead on the gear end, (shown in dotted lines in Fig. 3,) which holds-the clamping-plate f tight when pressed over the rack 1 Fig. 3. If the top sheet of this pile-blanket should be soiled by the varnish, it can be cleaned instantly by tearing one sheet off from the pile, when a clean surface is presented to receive the next sheet to be varnished.

Besides the gripers g (which are operated in the same manner as in a cylinder printin g-press by means of a tumbler, n, engaging the rollers I) b on the inside of the frame in the usual manner) there is also a series of lifting-fingers, g, on the shaft 9 which strip the boards off the packing of the cylinder and lift them onto the fingers a leading to the apron. These fingers g are operated by a lever, on the same shaft, striking a roller, 1), on the inside of the frame, Figs. 2 and 3.

The rollers D D, on which the apron runs, are provided with sprocket-wh eels on each end, which drive a safety-chain, C, which has lugs or cars l projecting to one side, to which the canvas of the apron O is riveted to prevent it from shifting on the rollers. (See Fig. 9.)

The roller S is adjustable in the segments Q R (in order to tighten the apron) by means of the sliding 'ournal-boxes 13, Figs. 3 and 4.

The machine is driven by a cone-pulley on roller-shaft. N, which has also a small gearwheel, 1,inside of the frame. This wheel gears into a small idler, 2, which runs loose on the shaft a, Fig. 3, which gears into the wheel N on the shaft M, and drives the cylinder and the varnish-rolls as previously described.

The two sprocket-wheels on the roller 1) are fast, and the diameter of the roller corresponds with the pitch-line of the sprocket-wheels. All the other sprockets carrying the chain are loose upon their rollers, and free to turn with the chain, regardless of the speed of the roller; hence no adjustment of the relative diameters of the sprocket and roller is necessary in the construction of these wheels. The sprocketwheels are kept apart the distance required to hold the chain and apron taut sidewise, and prevent sagging or gathering up.

The operation has been for the most part suggested in the description of the machine. The sheets are fed face down, by hand, to the cylinder from the front section, B, of the feedtable, which is raised to deliver the sheet to the gripers g. The sheets are then carried over the glossing-roll H, receiving the required coat of varnish; hence, being released by the gripers, they pass over the stripping-fingers to the apron G, by which they are carried down the swinging frame to the off bearers to be borne to the drying apparatus.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is-

1. In a glossing-machine, in combination with the driving and supporting rollers D D and the swinging frame It, the broad apron O, for delivering the varnished sheets, as described.

2. The described device for tripping the fountain, the same consisting of the combination, with the fountain G, of the brackets I l, lever K, and treadle L, all constructed, arranged, and operating substantially as set forth.

3. The combination of the sprocket-wheels on shafts D D D with the safety-chain and the apron O, in the manner and for the purpose specified.

4. The swinging frame It, hung on journals concentric with those of the roller D, which supports and carries the apron (J, in the manner and for the purpose stated.

In testimony that we claim the foregoing as our own invention we affix our signatures
