,SIGNORS TO VACUUM OIL COMPANY, OF NEW YORK YORK, N.-Y., A CORPORATION OF NEW INCLOSURE FOR ARTICLES BEING SPEAYED Application filed May 14,

The present invention relates to inclosures for articles being sprayed and an object of the invention is to provide an inclosure into which Cylindrical receptacles may be readily fed from a conveyor and from which they may be readily discharged onto another conveyor. Another object of the invention is to provide a casing having inlet and outlet doors on opposite sides thereof and provided with a rotary means which permits all portions of a container to move past a spray gun posi tioned at one point in the casing. Still another object of the invention is to provide for covering the upper head of a container as it is being rotated in an inclosed casing past a spray gun, in order to protect the head against this spray. A still'further'object of this invention is to provide a common operating means for the'doors of a casing and a cover for a container rotating in the casing past a spray gun.

To these and other ends, the invention consists of certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings:

Fig. 1 is a view in elevation of an apparatus constructed in accordance with this in vention; 1

Fig. 2 is a plan view of the same appara' tus;

Fig. 3 is a rear view;

Fig. 4 is a view of the intake side of apparatus;

Fig. 5 is a vertical section through the apparatus; a

Fig. 6 is a detail view of the clutch operating mechanism; and

Fig. 7 is a detailview of the head cover operating mechanism. 4

In the illustrated embodiment of the invention there is provided a main frame 1 supthe porting a casing or housing comprising, in

this instance, two segments 2 of a circular wall. spacedat their lower ends from the lower part of the frame and spaced at their vertical edges from each other to provide an intake opening and an outlet opening 3 and 4 respectively. The intake opening is closed 1927. Serial No. 191,506.

by a door 5 while the outlet opening is closed by a door 6, the door 5 being narrower than the intake opening so that a vertically extending opening 7 is provided between the free edge of the door and the adjacent edge of one of the wall sections 2 through which a spray gun may be operated. The door 5 has a hinge bar 8 turning in bearings 9 while the In this instance, the hinge bars 9 and 10 have arms 13 extending laterally from their upper end. .To one of these arms a link 14 is pivoted at 15, said link in turn being pivoted at 16 to 1 an operating lever 17 which is pivoted at one end 18 to the frame 1 and has its other end provided with a grip 19. 'To the other arm 13, a link 20 is pivoted at 21, this link 20 also being pivoted at 22 to a link 23 which is pivotally connected at 24 to the knuckle of a toggle formed by two

links

25 and 26, the former being pivoted at 27 to the frame 1 and the latterbeing pivoted at 28 to the lever 17. It is apparent with this arrangement, the movement of the operating lever 17 in one direction effects the simultaneous opening of the intake and outlet doors, whereas the movement of the lever 17 in the other direction effects the simultaneous closing of thedoors.

Within the -lower portion of the casing is mounted to turn arotary table or support 29 which may have a pulley 30 beneath the same operated in any suitable manner. In this instance, a belt 31 passesabout the pulley 30, thence upwardly about two pulleys 32 to a loose pulley 33 on a drive shaft 40. This drive shaft carries a drive pulley 41 which through a clytch connection 42 is adapted to establish driving connection with the pulley 41 in order to effect the turning of the table or rotary support 29.

In order to effect the automatic stopping and turning of the rotary table 29, the movable member of the clutch connection 42 may be connected to a lever 43 which. is pivoted at 44 to the frame of the apparatus and has a depending end. Pivoted at 45 to the lower end of the lever 43 is a rod 46, the otherend of which is pivoted at 47 to the operating lever 17 so that when the operating lever is moved to close the doors, the clutch connec-' tion 42 will be established and the rotary support 29 will start a motion, whereas, when the operating lever 17 is moved in the opposite direction, to open the doors, the clutch connection will be broken and the rotary support will cease its rotation.

With the end in view of protecting the upper head of the receptacle against the spray, a head protector or cover 48 is em-. This head protector is inthe form ployed. of aconcavo-convex disk 48, rotatably sup ported on the lower end of a rod 49, which is guided for vertical movement through the the link in turn being pivoted at 47 to the lever 17. The apparatus is preferably used in connection with a feeding conveyor 57 and "a a discharge conveyor 58.

The operation of the invention will be understood from the foregoing but will be summarized as follows: the containers 59 move along the feeding conveyor 57, while an operative stands at one side of the feeding conveyor in, position to grasp the handle I9 of the operating lever 17. Movement of this lever in one direction opens both doors 5 and 6 of the apparatus and also elevates the cover 48 and stops the rotation of the table 49. The

operative with his hand pushes the container 59 onto the table or support 29 and this container displaces a container from the rotary support onto the discharge conveyor 58.

. When the newly entered container is properly centered on the rotary support 29, theoperative moves the lever 17 in the other direction, thus closing both doors 5 and 6, starting the rotation of the rotary support 29 and moving the cover 48 into engagement with the upper head of the container. The concave surface of this cover tends to properly center the container on the rotary support as the center of this concave surface is vertically above the axis of rotation of the rotary support. The operative with a spray gun of any suitable construction sprays the container through the opening 7 and the fumes from this coating material pass off through a discharge flue 60.

What we claim as. our invention and desire to secure by Letters Patent is 1. apparatus of the class described comprising a casing having a door, a rotary container support mounted in the casing to engage one end of the container, a cover mounted in the casing for engaging the opposite end of the container and common controlling means for effecting the closing of the door and the movement of the cover toward the rotary support. a 1

2.
