JAMES F. GOUNLEY, OIF PHILADELPHIA. PENNSYLVANIA. ASSIGNOR TO ROYAL ELECTROTYPE COMPANY, A CORPORATION 0F PENNSYLVANIA4 BLACKLEADING- MACHINE.

Application led November 18, 1911.

T0 all whom it may concern.'

Be it known that I, JAMES F. GOUNLEY, a citizen of the United States, and a resident of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Blackleading-Machines, whereof the following is a specification, reference being had to the accompanying drawings.

This invention particularly relates to machines of the class by which matrices of the like are coated by spraying with a graphite laden liquid.

It is well known in the art of liquid coating to provide a reciprocatory table or carrier for matrices, whereby they are recipro cated in a bath of graphite laden liquid beneath a transversely disposed slotted pipe or nozzle, which directs said liquid in a transverse line. This method has been found to be ineicient, as it not only requires considerable time to separately coat each matrix, but also permits sediment, comprising the suspended particles of graphite, to lodge or collect in the angles at the bottom of the type impressions, in that portion of the matrix which is submerged and which is not being acted upon by the stream of liquid under pressure. By reason of the lodgment of the particles of suspended graphite, the graphite coated matrices are required to be thoroughly rinsed in a separate machine, to rlispose of the surplus graphite thus coll =cted, whereby considerable of said graphite is either wasted, or means must be provided for collecting it in a separate receptacle.

The principal object of this invention is to obviate the disadvantages and to eliminate the diiiculties found in machines of known construction, and to provide a machine that will not only save the time of the operator, but will more eiiiciently provide a uniformly thin coating of electrically conductive material upon the articles treated.

Other objects of this invention are to provide a machine of the class contemplated, with a continuously progressed conveyer, upon which clectroplate matrices may be continuously fed at one end, and progressed at a predetermined speed beneath a series of spraying nozzles, and automatically discharged at the other end.

Further objects of this invention are to provide transversely disposed spraying nozzles having jet apertures radially dis- Specication of Letters Patent.

posed in regularly spaced transverse planes, to provide said nozzles in such spaced relation that the adjacent jets of the respective nozzles will overlap before impinging upon the articles being treated, to provide the jet apertures of the adjacent nozzles in relatively staggered relation, so that the adjacent sprays of relatively adjacent nozzles will respectively alternate, and to provide agitating nozzles along the bottom of the tank, for agitating the sediment.

Briefly stated, this invention includes an elongated tank having a conveyer belt arranged to be progressed with the tank subjacent to a series of suitably disposed parallel transversely extending nozzles which are so disposed with respect to each other as to provide an unbroken discharge upon said elt or carrier throughout nearly its entire extent, means for progressing said conveyer belt at a predetermined speed, and means for drawing liquid from the bottom of said Vtank and forcing it under pressure through said nozzles.

This invention further includes all of the various novel features of construction and arrangement hereinafter more definitely specified.

In the accompanying drawings, Figure 1 is a side elevational view of a machine constructed in accordance with this invention, a portion being broken away and shown in section for convenience of illustration. Fig. 2 is a transverse vertical sectional view of said machine taken on the line 2 2 in Fig. 1, and Fig. 3 is a detached view showing the nozzle per se, directing jets of liquid upon a wax matrix, which is shown in section for the convenience of illustrating the action of the spray on the type portion of the matrix, and the impreions formed by said typg.

said drawings the tank 5 is supported on suitable legs (i` and comprises the bottom wall 7, which is inclined from the opposite ends of said tank downwardly toward a. centrally disposed outlet aperture 8.

J ournaled in suitable bearings 10 in the side walls of the tank 5 are the rotatable shafts 11 and 1'2, which respectively carry sprocket wheels 13 and 14. Said sprocket wheels 13 and 14 carry the sprocket chains 15. respectively connected hy suitable disposed parallel bars or slats 17, which are progressed by the rotation of said shafts 11 and 12, and

form a convenient belt conveyer for the carriage of matrices or the like to be treated.

The driven shaft l1 is provided with a worm gear 20 cooperative with the worm '21, on the shaft 22, which is journaled in bearings in 23 and 24, and which is provided with the driving pulley 25, for connection with any suitable form of motive power.

To each of the side Walls of the tank 5 is secured a. track rail 28, preferably formed of angle-iron, whose extending horizontal web 29 provides a track upon which the sprocket chains of the conveyer belt 18 rides, and which is slightly bent downwardly at its forward end 30 to facilitate the proper engagement of said chains therewith.

The discharge end wall 32of the tank 5 terminates short of the upper perimeter of 'the tank, substantially in a plane with the upper surface of the conveyer 18, and is provided with a. suitable outwardly extending shelf 33, supported on brackets 34, upon which shelf the matrices 35 may be automatically discharged from said conveyer belt, and may be conveniently removed therefrom by the operator.

The outlet aperture 8 is conveniently connected by the outlet pipe 40 with the inlet l1 of the contriugal pump 45, having the shaft 46 provided with the pulley 47 for connection with suitablemotive power. The outlet 48 of the centrifugal pump 45 is connected by the pipe 50 with the distributing pipe 52, comprisin the T-ittings 53 and the L-fittings 55, an Y supported by the bridge brackets 57, extending from the walls of the tank 5. The fittings 53 and 55= are each provided with laterally extending nozzle sections 60, disposedin parallel relation to each other, andin transvers'erelation with respect to the travel of the couveyer. Said nozzle sections each comprise a removable lower half section 62 connected with the upper section by bolted flanges 64 andi 65,V respectively integral with, and circumscribing the perimeteis of said sections. Each of the lower half sections 62 of the nozzles are provided with jet outlet apertures, which are disposed radially through the wall of said lower sections 62, in transverse parallel planes equally spaced at suitable distances throughout the longitudinal extent of said nozzles, it being notedtha-t the outlet apertures of the respectively adjacent nozzles are disposed in equally spaced alternate planes, or in other words. in staggered relation, so that the-sprays of the nozzle at the receiving endIof the machine, alternate with .the sprays 71 of the adjacent nozzle, and the sprays 72 of the last mentioned nozzle alternate with-the sprays 73' of theA next succeeding nozzle, and the sprays 74 of the last mentioned nozzle alternate with the sprays 75 of the next succeeding nozzle at thedischarge end of the machine. It may be here noted that owing to the fact that the 0'raphite is merely held in suspension in the iquid, it is likely to form sediment in the bottom of the tank 5, and therefore the nozzles and 81 are provided near the ends of A said tank 5, and extending transversely thereof and having jet outlets for directing agitating jets toward the outlet aperture S; said nozzle being respectively connected by the pipe 82, with the pressure pipe 50.

It will be seen from the foregoing descrip` tion, that the relation of the respective nozzles and their respective outlet a ertures, is an important factor in t'ie uni crm treatment of the matrices carried by the conveyer belt, and that when a matrix 1s placed upon said conveyer belt, it is continually sprayed during its progression from the receiving end of the machine to the discharging end, and therefore no interruptionV or intermission in the treatment of the matrix is eii'ected, and the sprays are so directed that every crevice in the matrix receives equal treatment with the prominent portions thereof, and furthermore, by reason of the fact tliat the spraying action is uninterrupted, the possibility of sediment being lodged in the crevices and caking therein isentirely eliminated, which fact is advantageous, in that little or no rinsing o'f the treated plate is required when discharged from a machine constructed in accordanceV with this invention, and therefore waste, by surplus material being lodged in the crevices of the matrix would he impossible.

It is not desired= to limit this invention to the precise details of construction and arrangement herein set forth, as various modifcations may be made therein, without departing from the essential features andscope of the invention as herein set forth and delined in the appended claims.
