apparent that this mode of driving the rolls greatly impairs their efficiency as their speed varies in proportion to the speed at which the machine is being run. It being desirable that the cleaning rolls of a bronzing machine revolve at a constant predetermined speed independent of the speed of the machine which may be inched or run slow for cer-` tain types of work, it is therefore, an object of this invention to provide means for driving the cleaning rolls of a bronzing machine independently of the machine per se.

Another object of this invention resides in the provision of means for driving the cleaning rolls of a bronzing machine which utilizes the prime mover or motor by which the exhauster is driven. f

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

In the accompanying drawing, I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the-r and 8. As' the speed at which the cleaning -roll 16 is`-driven, does not affect the quality principles thereof, and in which The single view is a side elevational view of the gear side of a bronzing machine, parts being broken away and in section to illustrate structural details.

type described in my copending application, Serial No.285,030 iiled June 13, 1928 and 6 the feed side frame thereof. Bronzing machinesv of this type are usually placed so as to receive work directly from the press overC S5 v tapes 7 from' whereit is picked up by a bronzing cylinder 8 to be carried past a bronzing roll or brush 9 which deposits bronzing material carried in abin or trough 10 onto the P work.--A bronzing pad llurubs the `bronze'vo into the work as it passes therebeneath and a series of cleaning rolls l2 rapidly rotated in atdirection opposite tofthe direction of movement of thev work by means to be later described,remove he excess bronze which is i5 drawn from the interior of the machine by an exhauster 13 through a passage 14.

After `passing the cleaning rolls 12,V the work is Vtransferred from the bronzing cyl-r l inder to a delivery cylinder 15, on which thefo under surface of the sheet or work is cleaned by af'cleaning-roll 16 before the sheet is deposited onto the delivery tapes 17 to be discharged into a receiving box 18, or delivered in any other suitable manner. "7775 As isrcustomary, the drive for the bronzing machine is taken directly from the press, not shown, with which the machine is used so that the bronzing machine travels at a` speed proportionate to the speed of the# press, the drive being obtained by means of a belt 18 passed about a pulley, not shown, carried by the press and a drive pulley 19 fixed to a main drive shaft 20. The shaft 20N is suitably journaled in bearings carried by the frame 5 and a bearing member 21, and has mounted thereon a drive pinionv 22 which meshes'with a'ring gear 23 carried by the delivery cylinder 15, a similar ring gear 24 lbeing secured to' the bronzing cylinder so that the pinion 22 drives the cylinders 15 of the work, as it merely cleans the under side thereof, itreceives its drive through an 9b idler 25 meshing with the ring gear 23 and function properly must be drivenr at a con- Gis' depositing bronzing material onto the work, cleaning means for removing excess bronzing material from the work, an exhauster, an exhauster drive, and means for driving the cleaning means from the exhauster drive independently of the drive for the work carrying means.

the chain extends downwardly around an adjustably mounted idler 34 which is'prof' vided with screw means 35 for maintaining the chain taut.

The shaft 33 has mounted thereon out- Wardly. of the sprocket 32 another sprocket 36 about which a chain 37 is trained to be driven thereby from a motor' 38 having a drive sprocket 39 meshing with the chain. The chain 37 is also trained about thedrive sprocket 40 of the exhauster 13 and forms substantially a triangle with the sprockets 36, 39 and 40 forming the Vapexes thereof. The motor 38 is mounted on a base 41 which is hingedly supported at one end from a stud or shaft 42 carried by the frame 5 so that the Weight of the motor is supported entirely by the sprocket chain 37 and thus maintains the same taut and in engagement.

with its sprockets.

From the foregoing description taken in connection with the accompanying drawing, it will be readily apparent tothose skilled in the art to which an invention or this characterV appertainsthat I provide a drive for the cleaning rolls of a bronzing machine which is entirely independent of the drive for the machine per se and one in which the speed of the rolls is at all times maintained at a constant predetermined value to assure the eilicient operation thereof.

Vhat I claim as my invention is:

1. In a bronzing machine, la Work carrying means, means for driving the work carrying means to carry the work through the machine, means for depositing bronzingmaterial onto the work, means for rubbing the bronzing material into the work, cleaning rolls for removing excess bronzing material from the work, an exhauster for withdrawing the bronzing material from the machine, sprockets carried by the cleaning rolls, a sprocket chain drivingly connecting the sprocket-s of the cleaning rolls, avdrive sprocket for said sprocket chain, means for driving the exhauster, and means whereby said exhauster drive drives the Vdrive sprockets of the cleaning rolls whereby the-cleaning rolls are drive-n at a constant predetermined speed irrespective of the speed of the bronzing machine per se.y

2. In a bronzing machine, work carrying means, means for driving said means to carry the work through the machine, means for
