HENRY A. HOUSE, JR., OF BUFFALO, NEW YORK, ASSIGNOR TO WIRE WHEEL CORPO- BATION OF AMERICA, OF NEW YORK, Y., A CORPORATION OF NEW YORK.
Specification of Letters Patent.
Patented Feb. 15, 1921.
To all whom it may concern:
Be it known that I, HENRY A. HOUSE, J r., a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Painting-Booths; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to figures of reference marked thereon, which form part of-this specification.
Like figures of reference refer to like parts.
This invention relates to painting booths; particularly to that kind thereof, which are adapted for positioning, within the booth, wheels or other round objects, to be liquid coated, either by hand or air brush.
One object of this invention is to provide a painting booth, with ventilating passages and means for producing a forced draft therethrough.
Another object is to provide an upright chimney as one of the draft passages, allowing the paint to drop within, before the air leaves the chimney.
Another object is to provide the inner walls of the booth with a removable covering upon which the excess paint can lodge, and thus'afi'ord a ready means for reclaiming paint which is usually wasted, besides facilitating the cleaning of the inner walls of the booth without much interruption in the service of the booth.
A further object is to provide means for revolving the round object within the booth while being painted, and also to turn said round object, to present i s reverse side to be covered.
A further object isto provide means for isolating the coating liquid from all revolving parts of the machinery, while in the action of creating the forced draft or revolving the round object being treated.
Another object is to provide readily releasable means for positioning, and holding the round object, for the coating operation.
Another object is to provide means for reversing the rotation of the round object.
ing features; means for rotating the ob ject in either direction, while being painted, means for positioning and holding about a vertlcal axis, a given object to be rotated, means for reversing the rotation of said obect, means for making a forced draft, means for protecting the bearings from the coating liquid, and a motor.
One embodiment of my invention is illustrated in the drawings and hereafter descr bed, the operation is explained, and what I claim is set forth,
In the drawings.
Figure 1, is a sectional side elevation of a painting booth, embodying one form of my invention.
Fig. 2, isa front elevation of the booth shown in Fig. 1.
Fig. 3, .is a sectional elevation of the upper fan bearing, showing the lubricant feeding mechanism.
Fig. 4, is a sectional elevation of the turning mechanism, including the automatic lock for holding the object in a given position for coating.
Referring to the figures, in Fig. 1, the main part for the frame marked 1, is shown having a top 2, to which is attached an elec tric motor 3. Extending on either side of the frame, part 1, are two 'hollow arms 4 and 5. The arm 1 terminates in a frame-work 6, and the arm 5 terminates in a framework 7. The frame-work 7 is partially supported on the standard 8. Bolted to the top 2 is the drain frame 9, which acts to support the cylindrical part 10 of the booth. A strut 11, acts to steady the booth on the top 2. Extending from the part 2, is the conical. part 12, connected with the chimney 13, by the short pipe 14. In the wall of the chimney 13, is the door 15, and in the lower end of the chimney 13, is the removable bottom 16.
Within the chimney 13, is the fan 17 mounted on the shaft 18, which is journaled in the special bearing 19, held central within the chimney 13, by the struts 20 and 21. The
strut 21 is hollow and is connected with the grease forcing cup 22. Holes 23,23 in the bearing 19 serve to communicate the surface of the shaft 18, in the bearing 19, with the bore of the tube or strut 21. Depending from the bearing 19, is the tube 24, to which is attached the hood 25, spaced from the up- ,standing thimble 26. Passing through the motor 3, is the shaft 27, connected with the shaft 18 by the coupling 28. The lower part of the shaft 27 is journaled in the frame-work 6 and has mounted thereon the bevel gear 29, which meshes with the gear 30, fixed on the shaft 31. The shaft 31 is journale'd in bearings 4 and 5 in the arms 4 and 5 respectively, and extends across the frame-work 7, in which it is also journaled Inspliced engagement upon the shaft is the sleeve 32, having fixed thereon the-two friction cones 33 and 34. The sleeve 32 has extending on opposite sides thereof, posts marked 35, which engage forked levers 36, respectively. The forked levers 36, are fixed to a yoke 37, and are pivoted at 38 and connected with the crank-arm 39, by the links and 41. The crank-arm 39 is fixed to a' short-shaft 42, journaled in the support 43.
Fixed to the outer end of the shaft 42, is the 40 '7, and is concentric within the tube 50, which rests in a socket in the upper part of the frame-work 7. The tube 50 is in turning engagement with the tubular boss 51, of the drain frame 9. Between the drain frame 9, and the frame-work 7, and in turning engagement with the tube 50, is the hub 52 of the hand wheel 53. Inside of the hub 52 is the castellated top 54, of the frame-work 7, having teeth 54. In sliding engagement with the tube 50 and between the hub 52 and the tube 50, is the cylindrical sleeve 55, havin a longitudinal slot 56, engaging a pin 5 fixed in the tube 50. A notch 57, having tion of the parts within the hub 52 is better shown on a larger scale in Fig. 4). Fixed having fixed at its lower end,
its upper part inclined in opposite 55 directions, is engaged by the inner end of a to the tube 50 and extending concentrically over the tubular boss 51, is the shield 63. A globular frame 64, is mounted upon the upper end of the tube 50, and has journaled in it the upper part of the shaft 47, and the short inclined shaft 65. Fixed to the shaft 47, is the bevel gear 66, which meshes with the gear 67, on the shaft 65. A wheel 68 is shown'positioned upon a holder 65*, on the outer part of the shaft 65. This holder is .made up of a cylindrical ortion 69, engaging the shaft 65, a flange 0, adapted by its shape to engage the inner tapered surface of the hub 71, of the wheel 68, is inte ml and concentric with the portion 69. ut wardly spring-pressed fingers 72, pivoted at 73, on the portion 69, engage the tapered surface within the outer end of the hub 71. The springs pressing the fingers 72 outward, are numbered 7 2.
The inside of the booth parts 10 and 12 are shown lined by the covering 74, partly broken away. To the outer and upper portion of the part 10-, is fixed the bracket 75, supporting the reflecting hood 76. An electric bulb 77 is shown within the hood 76.
In operation, a wheel 68 is positioned upon the holder 65, on the shaft 65, the shaft 65 being first positioned as shown in Fig. 1. The motor 3 is next started and revolves the fan 17, and the sleeve 32. The 9 operators foot is next pressed upon either one of the ears 45, 46, as desired to cause one or the other of the cones 33 or 34, to contact the cones 48 and revolve the shaft 47 and subsequently the wheel 68 in the direction desired. A spray of coating liquid is next directed into the booth, against the wheel 68, while it is being motor rotated. I use the usual hand air brush for this work. While the liquid is being applied, a draft created by the fan draws the liquid spray in against the wheel 68, and some of the excess spray lodges against the covering 74; some finds its way onto the tube 50, and running down is guided outside the tubular boss 51 into the drain 9 and with other accumulated liquid finds its way out the spout 9 into the can 9. The spray which is drawn into the chimney 13, is precipitated into the bottom 16, and that portion which lodges upon the tube 24, runs down and is guided by the thimble 25 into the bottom 16. Some liquid will lodge upon the bearing 19, and will tend to mix with the lubricant, oozing from between the shaft 18 of the bearing 19. During the use of the booth, the grease gun 22, presses a supply of lubricant slowly through the tube 21 and into thejholes 23, of the bearing 19, and out between xth'e shaft 18 and the bearing 19, preventing the inflow of the coating liquid, running along the shaft 18 into the bearing 19.
After the face of the wheel 68 is coated,
the foot-lever 44 is released, disconnecting the motor 3, and the operator turns the hand wheel 53 partiall until the set-screw 58, engaging one of t e inclined walls in the upper part of the recess 51, forces the sleeve 55 upward, releasing the tooth .59, from engagement with the teeth 54,54, and upon further turning'of the hand wheel-53, the set-screw 58, pressing against the vertical art of the wall of the recess 51, carries t e sleeve 55 with it, and in turn the sleeve 55, pressing against the pin 37, in the slot 56, carries the tube 50 with it, turning the wheel68 around in thg booth, into the.
dotted position 68, so as to present its re- .verse side for coating. Upon letting go the hand wheel 53, the spring 61, forces the sleeve 55 downward, and the tooth 59 enters a space between two consecutive teeth 54, 54, and locks automatically, the position of the axis of the wheel 68 within the booth. The operator next presses down the opposite ear to that which he first pressed, and kept down during the coating of the face of the wheel 68, and the wheel is then oppositely rotated with respect to the globu lar frame 64, but in the samedirection with res ect to the operator.
urin the coating operation the lamp 77 illumlnates the object within'the booth beifig coated. odification of the embodiment of my invention, above described and shown, may be made without de arting from the spirit and scope thereof; I therefore do not wish to be confined to this one embodiment.
