This invention relates to conveyers in which a driver, usually a Hexible belt or chain, propels articles along a rail or guideway.

The objects of the invention are to improve the construction of such conveyers by substituting simple standardized parts for the specially designed and relatively complicated conveyer and guideway units of the prior art, and to provide for quick and easy removal or insertion of standardized conveyer units in accordance with variations of the working requirements or the need for replacement of worn parts. .Further objects of the invention and features of construction will be made apparent in the course of the following description.

By way of illustrative embodiment there is shown in the drawings and hereinafter described a continuously operating electroplating apparatus; but the invention is capable of many other uses.

In the drawings,

Figure 1 is 'a plan view, partly broken away, of an electroplating tank equipped with my improved conveyer;

Figures 2 and 3 are enlarged detail views in elevation of a portion of a conveyer chain and adjacent parts; A Figure 4 is a fragmentary transverse section on the line 4 4 of Figure 1;

Figure 5 is an enlarged fragmentary View in plan, based upon Figure 1;

Figure 6 is a horizontal section on line 6-6 of Figure 4;

Figure 7 is an enlarged perspective view of a bridge member;

Figure 8.is a transverse sectional view on line 8-8 of Figure'l, the central portion only being shown; and

Figure 9 is a fragmentary view vased upon Figure 8, but showing the parts in a different relation.

Referring tothe drawings in detail, 1 designates a tank containing an electrolytic bath 2. Insulated brackets 3, secured to the side walls of the tank, support an anode bar 4, from which hooked anodes 5 depend into the bath. Frames 6, mounted on the end walls of the tank, support parallel angle gird- `to sprocket along each ers 7 upon which the remaining parts of the aplpIaratus are mounted.

angers 8 and bus bars 9 are secured by bolts 10 Yto girders 7. Hangers 8 are of chan'- nel form and have perforated end walls 11,

through which machine screws-12 are tapped into the endless rail 13 which also serves `as a cathode bar (Figures 1 and .7 Work supporting hooks 14 are hung upon the rail or cathode bar 13 at intervals in position to be propelled along the -bar by the conveyer,

which is the subject of the present inventlon.

In the center of the tank an additional anode bar 15 is carried by hangers 16, which are secured to the irders 7 by means'of bolts 17 (Figure 8). bus bar 18 has a lowerl hooked end 19, which is clamped around bar 15 by means of bolt 20.

At opposite ends of the tank, driving sprocket 21 and idler sprocket 22 are suspended from the girders 7. The mounting of the- Asprockets is shown in detail with reference to the driving sprocket in Figure 4. The

sprocket is clamped upon squared portion 28 of stub shaft 24 by means of nut 25.- The stub shaft is journalled in abed plate 26, which rests upon girders 7, and also carries a suitable driving mechanism which is indicated diagrammatically.

An endless driver is provided,`\which, in the illustrative embodiment shown, takes theform of a chain 27, preferably composed of separable links 28 to facilitate assembling and adjustments of the length of the chain. The conveyer belt is also preferably perfo rated at regular intervals, and in the embodi- -ment shown, the desired perforations are supplied by employing links of a rectangular ring form. Chain 27 is in mesh with

sprockets

21 and 22, and is supported by bridge members 29 which pass through the links of the chain and rest at one end upon the outer rail or cathode bar 132 'and at the other end upon inner rails 30, which are secured to the hangers 8 (Figure 8), and extend from sprocket straight course of the conveyer. The supporting path formed by the rails v3() is completed by shoulders 31 on the upper faces of the sprockets. The shoulders lie in the plane of the rails 30 and in 4 members, at their inner ends, are transferred from the rails to the shoulders when rounding the sprockets, while the sprocket teeth en age links 28 beneath the bridge members i re 4). It will be observed that the bridgg; members, as they slide along the rails, will ca with themthe work supporting hooks 14. The outer rail or cathode bar 1S kept clean and perfect electrical contactbetween the bar and work supporting hooks is thus maintained. The number of bridge members emplo ed ma be varied at will to correspond to e num r of work supportin hooks employed at a 'ven time.v

e outer ends 32 of t e bridge members are curved to conform to bar 13, and the inner ends are bifurcated to provide a pair of sup-k porting lugs 33 and a pair of vertical abutting faces 34. Thel 33 and abuttin faces 34 en ge rails 30 or s oulders 31, as t e case may at two points, one of which is in advance of the longitudinal axis of the bridge members, and the other of which is rearward thereof. With respect to the vertical abutting faces 34, this arrangement resists the turning tendenc of the bridge members under the forwar pull of the chain and the backward drag of the work supporting hooks and the separation of the faces 34 gives two plpints of contact with the shoulders 31 so at the alignment of the bridge members is maintained while they are rounding the sprockets. Se aration of the sup orting lugs 33 assists the ridge members w en passingfrom the rails 30 onto the shoulders 3l, since the rear lug will not leave the rail until the forward lug is securely seated upon the shoulder. L-sha guard plates 36 are shown and they may continued over the straight courses of the chain, but are not essential to Y the invention. For a greater part of their length the bridge members are of a crosssection which permits them to be readily passed through the links 28, thus facilitating insertion or withdrawal of the bridge members as required.` This operation of inserting or withdrawing bridge members is conveniently rformed upon raising the chain in the middle of one of its straight courses, as shown in Figures 3 and 9. The bridge inembers are provided on their upper faces with slots 35 which snu ly engage the links 28 to d guide the chain an furnish additional resistice to pivotal movements of the bridge memrs. The operation of the apparatus has been suiciently indicated in the foregoing description and, in general, the operation doesnot differ from that of known electroplating apparatus. It will be seen, however, that in contrast with known conveyer systems of this type, the present invention employs a few simple and separable parts whichare readily susoeptible of standardization. The outer rail 13, inner rails 30, and the conveyer chain, are of the simgilest possible construction, but

rform all o the required functions by virtue of the bridge members which support the chain and at t e same time engage and 'rol the work supporting hooks. -The c ain `is subjected to the least possible wearing friction, and the elaborate especially designed devices of the prior art for supporting the chain and engaging the articles to be conveyed are eliminated. The construction is open and free from pockets which would become clogged with dirt. I claim a pair of parallel rails, a drivin chain parallel to and between the rails an composed of perforate links, and travelin bridge members supplorted upon the rails an a w ole through the links.
