PLATING-MACHINE Specification of Letters Patent.

Patented July '7, 1908.

Application filed October 22, 1907. Serial No. 398,594.

To all whom it may concern:

Be it known that I, CHARLES GLovEn, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Plating-Machines, of which the following is a full, clear, and exact description.

My invention relates to improvements in plating machines.

.The objects of my invention are-to provide an improved construction for plating machines, including improvements in a carrier adapted to move certain conveyors through the plating solution, which conveyers may be readily detached at will for the substitution of new articles to be plated.

The particular advantages will be appreciated by a reading of the following descriptron.

In the drawings Figure 1 is a view in end elevation of the machine with the tank in section; Fig. 2 is a view in side elevation with the tank and bearings in section; Fig. 3 is a plan view of the plating machine; Fig. 4 is an enlarged detail view partly in section, and partly broken away; Fig. 5 is a transverse sectional view of Fig. 4; Figs. 6 and 7 are enlarged detail views of the opposite sides of one end of the conveyor frame.

1 is a tank adapted to contain the plating solution.

2 is a shaft mounted to rotate in the bearings 3, secured in the ends of the tank.

4 is a stuffing-box through which an extension of the shaft 2 passes. 5 is a pulleywheel secured to the said extension on the exterior of the tank.

66 are the ends of the carrier frame, the same being secured to the shaft 2.

7 is a container for articles to be plated. 8 is a supporting rod therefor. This rod may carry the articles directly or indirectly, as where the container 7 is used. In the latter case, the rod 8 passes through the con tainer at the centers of the ends 99. One or both of the ends 9 may be removable, or one may be fixed in the end of the container 7 and secured to the rod 8 as by key 8*, or if both ends are removable the container may be fastened to the rod 18 by a removable pin connection 7 and the key 8 (Fig. 4.)

10-10 are clips or buttons on the carrier frame 66 adapted to detachably engage the rod 8 and secure the same to the respective frames. 1

11 is a handle projecting from each end 9 of the container 7.

12 is a rheostat connected to the positive terminal of the source of electricity.

13 is an insulated connection between the rheostat 12 and a contact 15 on the bear ing 3.

14 is a reduced extension of the shaft 2. This extension 14 is mounted in the bearing 3 and makes electrical connection with the contact 15.

The carrier frame 6 may be formed in two sections. 1616 indicate a series of arms, radiating from and in contact with extension 14, on one section of 6, said arms being adapted to form a contact with the rods 8 when the same are secured in place. 16 is a ring secured in the opposite section of 6 and bears against the arms 1616, when the two sections are secured together.

17 indicates a series of metallic strips or rods, rotatably secured at one end to the rods 8.

1818 are sleeve-like spacers placed between the members 17 on rod 8.

19-19 indicate negative poles suspended in the plating solution and connected to gether in any well-known manner.

20 is a connection leading from the poles 19 to the negative pole of the source of electricity.

The main body of the shaft 2 is preferably made of wood, or some non-conducting material, and the same is true of the frame ends 6-6 The shaft extension passing through the stuffing-box 4 and the extension 14 are preferably made of metal, and are electrically disconnected at all times. It follows, therefore, that electricity entering through the wiring 13 can proceed. onwardly only by passing through the extension 1 1, arm 16, rods 8, the articles carried thereby, and thence through the solution to the negative terminals 19. leakage of electricity is afforded.

The cylindrical parts of the container 7 are preferably formed of celluloid, or some other efficient non-conducting material of sufficient strength for practical use in this construction, and preferably attached to one of the ends 9 which is secured against rotation.

The operation is as follows: The proper plating solution and anode terminals 19 are employed and put in place. The articles to be plated are then electrically connected with the rod 8. In case small articles are to be By this arrangement no chance of plated, Which cannot be conveniently secured to the rods 8, they are placed in the perforated barrels 77 and are kept in circuit through the medium of the rods 17, the rods and small articles assuming the same position in the barrel by gravity. Other articles Which, for example, are perforated, may be placed directly upon the rods 8, for instance, such as shown in the lower part of Fig. 2. These rods are detachably secured to the rotating frame through the medium of the clips or buttons 10 on the ends 6-6 The plating of the articles, hatever they may be, occurs in the usual manner and requires no. detailed description. The carrier frame Within the solution rotates at comparatively sloW speed, for example, five or six revolutions per minute, although the speed is immaterial. When rotating at a comparatively sloW speed, the operator in charge of the plating machine may easily and quickly remove any one of the rods 8 and the devices carried thereby and substitute another one. For convenience in removing the barrels, handles 11 are employed, al

though of course their presence is not absolutely essential.

The plating solution is preferably of such a depth as to always cover the articles to be plated When they are in proper position to receive the same.
