Application filed March 18, 1907. Serial No. 363,124.

To all whom it may concern:

Be it known that ALBERT F. SCHROEDER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, has invented certain new and useful Improvements in Electroplating Apparatus, of which the following is a specification.

My invention relates to an electro-plating apparatus of the class comprising an electro-plating tank having a rotatable receptacle supporter therein and immersed or partly immersed in the electro-plating fluid, and adapted to receive the articles to be plated.

The objects of my invention are to provide a supporting frame having novel means of holding and revolving the rotatable receptacle whereby it may be moved from the tank and the supporting frame without disturbing the mechanism.

on another tank in a minimum amount of time.

Still further objects are to provide novel means of roparallel with the shaft 12. Shaft 15 carries thereon a pulley 16, which may be connected to a source of power or which may be displaced and a crank substituted to manually rotate the elements, and said shaft also carries a small gear 17 meshing with and transmitting rotation to the gear 14 and sprocket wheel 13.

At the lower end of the casting 1 is formed an elongated opening 18 through which is vertically arranged thelsorew shaft 19 rotatable therein, but held from lon- I gitudinal displacement therefrom. A sprocket chain tating the receptacle and compensating for the wear of the mechanism employed and to combine the entire structure in a simple, cheap and portable device.

My invention resides therefore in the construction arrangement and operation by going objects as hereinafter described accompanying drawings, in which,

and shown in the Figure 1, is an elevation of my improved apparatus looking from below the horizontal plane thereof. Fig. 2, is an elevation of one end of the apparatus showing the same within the tank and detachably clasped thereto. Fig. 3, is an elevation of the other end of mydevice, and Fig. 4, is a horizontal section illustrating the manlower sprocket wheel.

Referring to the figures the inverted U shaped castings 1 and 2 form the end pieces of my improved apparatus, the same being held in spaced relation by means of the transverse bars 3, 4 and 5 and having lateral arms 6 on which are arranged open bearings 7 for the recepand the casting 1 is adapted to anism employed to transmit rotation to the shaft 8 and drum 9 as will now be described. A bracket 11 is conwhich I attain the fore 20 is arranged on the upper sprocket wheel 13 and drives a lower sprocket wheel 21 mounted on short shaft 22. The sprocket 9 mounted on the rotatable shaft 8 is arranged in the path of travel of said sprocket chain and its teeth engage therewith to rotate the shaft 8. It will thus be seen that by this novel way of driving the shaft 8 I am able to lift the drum 9 and shaft 8 from the bearings 7 without disturbing the other elements in the slightest. It may also be seen however, that after considerable wear the sprocket chain 20 is apt to become loose in fact so loose that the sprocket wheel 9il could not properly engage therewith to rotate. To obviate this difficulty I arrange the shaft 22 carrying the lower sprocket 2l adjustable in order that the chain 20 may loosened as desired, to compensate for wear and to allow the gear 9a to be replaced by a larger one when it is desired to rotate the drum 9 slower.

The shaft 22 is provided with a square end 23 slidably arranged Within the opening 18 and provided with a transverse threaded opening through which the screw shaft 19 is mounted. The squared end of shaft 22 is also provided with shoulders 24 arranged against the inner edges of the opening 18 and with a bearing plate 25 attached to the outer end thereof by means of a bolt 26 and spanning the said opening 18 on its outer edges. Shaft 22 is further provided with a screw threaded inner end having a nut 27 screwed thereon to hold the sprocket wheel 21.

The operation of my device is as follows. To install the mechanism it is simply necessary to clamp the castings on the side of the tank by means of the clamping thumb screws 10 and the clamping board same may be just as quickly and easily removed and installed in another tank after being Washed. The

means for driving shaft 15 having been coupled thereto and started, power is transmitted through gears 17 and 14 to the sprocket wheel 13 and the sprocket chain 2O in its travel about wheels 13 and 21, drives the sprocket wheel 9fL and consequently rotates the drum 9.

Having thus fully described my invention what I claim is,

1. In a device of the character described, a tumbling drum having a central shaft extending axially therethrough, castings for rotatably supporting said drum, a drivingl train and a gear wheel mounted on said shaft and nected on the upper end of said casting l and has mounted therein a short rotatable shaft 12 carrying a sprocket wheel 13 on one end and a gear wheel 14 on the other end thereof. A second short shaft 15 is journaled in an extension of the bracket 11 and is arranged detachably held against and in operative engagement with I with said driving train, whereby said drum may be re- 1() said driving train, whereby said drum may be removed inmoved independent of the other mechanism, substantially dependent of the other mechanism, substantially as deas described,
