BARTLETT Q comm, or 0310, a CORPORATION or 01110 mums! son. was In comma ananas AND 1.11m narrows ed to revolubly support such-barrelor article during the course of the coating rocess and to so support such articlethat t e exterior surface thereof is not marred or defaced in of varying an way by the means employed to su port it. an barrels are coated, that is, painted or similarly treated, it isessential that the bar- 'rels bisupport'ed on their chime rings so that wheifithe coating process is completed there will-ibe nodefects inv the finished surface. Also the mechanism which supports the barrels should be adapted'to discharge the same after the coating process is completed, and the discharging means should also be adapted to handle the barrel without contacting with the freshly coated surface. It is among the objects of my, invention to-provide a mechanism which shall revolubly support a barrel or cylindrical article in the above described manner.

The mechanism to be used in connection with the coating of barrels or cylindrical articles should be adaptable to be used with articles of varying lengths and diameters, and should be capable of adapting itself to handle such varying sizes with a minimum amount of adjustment which interferes with the operation of the machine. It is a further o ject of my invention to provide a mechanism which shall be adaptable to handle barrels len hs and diameterswithout the necessity o 'more than a minimum of adjustment of the various operative parts. Other objects of my invention willappear as the description roceeds.

To the accomphshment of the foregoing and related ends, said invention, then, con-' sists of the means hereinafter fully described and particularly pointed out in the claims; the annexed drawings and the following description setting forth indetail certain mechanism embodying the invention, such disclosed means constitutin however, but'one of various mechanical orms in which the principles of the invention may be used.

Referring more specificallyto the drawings, and more especially to those figures in which like ordinals are employed to designate like parts. The ordinals 1 and 2 are employed to designatethe longitudinal sides. of the base frame on which the mechanism is mounted and 3and 4 desi bers of such frame. Positioned on the side frame members 1 and 2 are transversely ex'- tending frames generally indicated by 5 and 6. The frames 5 and 6 are adapted to be moved longitudinally of the side frames 1 w and 2 by means of racks 7 and 8 being engaged by pinions 9 and 10,- which are rigidly secured to transverse shafts 11 and 12. The

shafts 11 and 12 have bevel gears 13 and 14 'securedthereto which are in mesh with similarly formed gears 15 and 16 terminally mounted on shaft 17. Actuation of this frame-moving mechanism is accomplished by a suitable crankhandle (not shown) engaging the extension 18 of the shaft 12. Upon 5 rotation of the shaft 12 by such handle or crank the transverse frames 5 and 6, with their associated mechanism, can be moved away from or toward each other, as most clearly shown in the dotted and full line po= sitions illustrated in Fig. 2. The transverse. frame 5 has revolubly mounted thereon shafts 20 and 21 which are journaled in bearings 22 and 23 which are removably secured to the transverse frame '5 by means of bolts 24 and 25. Terminally mounted on the shafts 20 and '21 are rollers 26 which have'their main portions preferably conical in form as at 27 and which1, have-circumferential flanges 28 formed'on one end. thereof. The shafts 20 and 21 have collars 29 mounted thereon which serve'as axial re straming means for these shafts in their bearings. Shafts 20 and 21 also carry sprocket wheels 30 which are interconnected by a flexible chain 31.

Mounted onthe terminal portion of the base of the machine, as most clearly shown on the leftin Fig. 2, is a transversely extend- 1 mg platform 32, which hass'ecurely mounted 00 gnate the end mem-.

' thereon a prime mover 33, here shown in the i shown).. The shaft 37 as adriving form of an electric motor. The drive shaft 34 of the motor 33has a driving gear 35 rigidly secured thereto which meshes with a driven gear 36 mounted "on a shaft 37. The shaft 37 extends longitudinally of the machine and is suitably journaled in s aced bearings, (not I pm1 on 38 rigidly secured thereto which mes es w1th a driven gear 39 secured to the shaft 20.

- The construction of the transverse frame 6 and its associated mechanism is identical with that just described in connection with transverse frame 5 so that like ordinals bearing prime marks will be employed to desilg; nate similar parts on the two frames.

' connectionwith the mechanism as shown mounted on the transverseframes 5 and 6 and the gearing in communication with the motor it w1ll be noted that all such mechanism an gearing is suitably enclosed in guards, such as 40, which protect such mechanism from the paint and like material which would be injhlirious to the operation thereof. v

ounted in bearings 41 and42, which are respectively carried b 5 and 6, is a 'longitu he transverse frames ally extending shaft 43, whichhas a collar 44 shown associated therewith to prevent axial movement thereof with respect to the bearing 41. The shaft 43 has rigidly mounted thereon a member 45 which is axially restrained with respect to the shaft 43. b means of a collar 46. As most clearly s own in Figs. 2 and-3 the member 45 has an extending army which is terminally formed intoa pad 48 adapted to receive the foot of the operator. The-p110 jecting' element 49' of the member 45 has rigidly secured thereto an operating handle 50 by means of bolts 51.

Rigidly secured to the shaft 43 is a radi- -ally extending arm 52 which is terminally adapted. to receive a stub shaft 53 which is secured thereto b means of a nut 54 enga ing the threade end thereof. Revolub y sup orted by the stub shaft 53 is a roller pre erably conical-in form and somewhat similar to roller 27, and which is axially restrained with respect to the shaft 53 by means ofthe nut 56. The shaft 43 has another radially extendin arm 57 revolubly secured thereto, but axia 1y slidable thereon, which arm 57 has a roller similar to roller revolubly secured thereto in the same manner.. As most clearly shown in Fig. 1, bracket member 58 is secured to the transverse frame 6 by means of a. bolt 59, and extending laterally therefrom has an upwardly bent end 60 and a similarly directedprojection 61 which rojections are adapted to enga e oppositeaces of the hub 62 of the arm 5 In this manner the arm 57 is maintained in the proper relation to the rollers 26 as'the transverse frame 6 is moved along the bed of the .machine.

, at the terminals thereof so that when The sides of the transverse frames 5 and '6 opposite the shaft 63, which is journaled in the bearings 64 and 65. The shaft 63 has a collar 66 rigidly secured thereto, which serves as an axial restraining means for this shaft with respect to the frame 5. Terminall mounted on the shaft63 is a member 66 whlch has an arm 67 formed integrally therewith and extendin radially therefrom. The terminal portion 0 the arm67 is adapted to receive a pin 68 by means of which. a lever 69 is oscillatably secured thereto. The oppositeend of the arm 69 is secured .to the lever 50 by means of a pin 70.

Rigidly secured to the shaft 63 at a point adjacent the transverse frame 5 is a rocker .63 has slidably keyed thereto at a point adjacent the frame member 6 another rocker member 71" which is formed similarly to the rocker member just described. The rocker member 71' has associated therewith a bracket similar to the bracket 58, which likewise maintainsthe rocker member 71"in proper relation with respect to. the transverse frame 6.

In the barrels to from a preferably inclined runway extending to the right of the machine, as viewed in Fig. 3. The barrels rest against the ends 74 of therocker members until the shaft 43 is rotated in a counter-clockwise direction, due to actuation b the operator of either the .pedal 47 or t e control handle 50. This counter-clockwise rotation of the shaft 43, through the arm 69, causes the clockwise rotation of the-shaft 63, which moves the rockter members 71 and 71' into the osition shown in dotted lines in Fig. 3. en the rekers 71 and 71' are in thisposition, a barreP -is permitted to roll thereon which, upon a reverse movement of the rockers, is permitted to roll onto the supporting rolls 26 and 26'. After the barrels ave been coated an actuation of the shafts 43 and 63 in themanner just described will cause a counter-clockogaration ofthis mechanism, the

wise rotation of the arms 52 and. 57, which i will cause the rollers "55 to engage the barrels at the peripheries thereof and laterally move the same oi the rollers 26 and 26' onto receiving skids (not shown).

By a proper actuation of the shaft 18, which will impart rotation -to the shaft 17, the transverse frames 5'and 6 may be so s 'aced that the distance between the circumf tial flan es 28 and 28 on the rollers 26 and 26' will just the length of the barrel which is to be received by the machine. When the transverse arms 5 and 6 are so ositioned on the base the barrels or like cylmdrical articles will be supported on their peri heiries coated are fedto the machine 9 erenrels are rotated and the coating applied thereto the fresh coating will not be marred by the supporting mechanism. The rollers 55, which are associated with the discharge arms 52 and 57 are adapted to similarly engage the barrel or cylindrical article so that when the barrel has once been coated the exterior thereof will in no way be marred incidental to its movement from the painting machine.

The motor 33, through the gear train described in connection therewith, effects a positive drive to each roller of the machine so that a constant rotation of the supported barrel takes place while the barrel is positioned on the machine, which rotation permits the operator to spray or otherwise apply the coating to the barrel over its entire periphery.

It will be seen in connection with the above description that the mechanism comprising my invention is particularly applicable to be used in the coating of barrels and like articles and that the manner in which such barrels are subjected is different from, and has advantages over, any means heretofore em ployed to support cylindrical articles during the coating process. Only so much of my invention has been described as has been considered pertinent to the operation thereof and the description is believed to be sufiicient for those acquainted with the art of coating cylindrical articles, suffice it to say that detail changes might be made in the various forms of the construction here chosen for purposes of illustration without in any way departing from the principles of my invention.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1.
