Claims. l
This invention relates to machines for wiping and coating surfaces of material, and more particu-ariy to machines for applying a heavy viscous coating to the inside of panels, such as automobile doors. f
The primary object of the invention is to provide an improved method and machine for applying heavy viscous coatings, such as soundprooiing material, to door panels, and the like, so that a smooth and even coating can be quickly and inexpensively adhered to the surface.
Another object of the invention is to provide a machine wherein the applicator roll is covered with soft yielding material which will first wipe the surface to be coated and immediately app y a viscous coating.
Another object of the invention is to provide a machine wherein the coating material is wiped from a feed box onto an applicator roll which wipes the material onto the surface to be coated, the applicator roll wipes foreign material from the work surface, and it in return is wiped by the transfer roll.
A further object of the inventionis to provide a machine which can apply coatings to curved surfaces, and to provide improved driving means for the roll and a carriage for moving the panels into coating position.
The invention is illustrated in a preferred embodiment in the accompanying drawings in which- Figure 1 is a fragmentary side elevational view, partly in section, showing the improved machine; and Fig. 2 is a fragmentary plan view of the same.
In the embodiment illustrated, a base member 3 may have suitable legs 4 to support tracks 5 at a convenient height for a carriage 6. The carriage may have rollers 1, so that it may be moved back and forth on the tracks 5. It is also provided with a suitable fixture 8 to support work material which may be a curved metal panel 9 which can be made into the door for an automobile.
The base is provided with supports I0 which pivotally support at I I a metal supporting frame I2. One end of the frame is provided with a troughlike feed box I3 for holding a supply of viscous material, such as a mixture of asphalt and sand used for sound deadening purposes. The trough is shown supported on slotted uprights I4, so that its height may be adjusted by wing nuts I5.
A smooth metal transfer roll I6 is journalled in the uprights III, so that it rotates through the lower portion of the feed box and makes contact with the viscous material in the box. The front of the box is shown provided with a doctor blade Il, which is adjustable vertically by means of wing nuts I8, to regulate the thickness of the material adhering to the transfer roll as it turns out of the box. An applicator roll I9 also is journalled in the uprights Ill and contacts the roll I6. Preferably, the roll i9 is provided with a soft rubber-like coating 20, so that it will make yielding rubbing contact with the transfer roll Ie and the work material 9. As shown in Fig. 1, one end of the roll may be supported by a slotted bearing 2l, to enable it to accommodate itself to slight longitudinal irregularities in the panel 9. however, in order to apply a coating successfully, it is necessary to maintain wiping contact with the roll I6.
The rear end of the frame l2 is provided with an electric motor 22, which drives a sprocket wheel 23 through a conventional gear reduction 2li. 'The sprocket wheel 23 drives a sprocket wheel 25 on the roll i6 by means of a sprocket chain 26. The opposite end of the roll I6 is provided with a sprocket wheel 2'I which drives a sprocket wheel on the roll Zal, by means of a sprocket chain 28. It will be noted that the rolls Ib` and 2U rotate in the same direction, so that a wiping contact is made between them. Also, the panel l is rolled to the applicator roll 20 in the opposite direction to the direction of rotation, so that the work material or panel 9 is first wiped free of oil or other foreign material by the applicator roll, and then the viscous material is deposited on the surface by a rubbing action. It is common to find oil on the panel 9 which has been applied as a rust preventative. This material is picked up by the applicator roll and carried up to the transfer roll where it is wiped off and carried up into the feed box, where it has been found it causes no harm to the viscous coating material.
The fact that the frame may swing on the pivot l I enables the rolls to be raised or lowered to conform to the surface which is to be worked upon, and the machine has been found to Work satisfactori y on door panels which have both longitudinal and lateral irregularities.
The motor is provided with suitable Switches, not shown, which may be operated automatically to start and stop the machine, as a panel is moved into or out of proper coating position. It will be understood that when the rolls are in raised position a panel 9 is placed on the fixture 8 and rolled into position to receive a coating 29. When a 3 desired amount of surface is coated, the machine is stopped, the rolls raised, and the carriage rolled out so that the treated panel may be replaced.
Ihe foregoing detailed description is given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, for some modifications will be obvious to those skilled in the art.
I claim:
1. A machine of the character set forth, comprising, a base member having a track, a supporting frame pivotally mounted on said base member, a feed-box adjustably mounted on said frame for holding viscous material, a transfer roll journalled in said frame so as to rotate through the lower portion of the feed-box, an applicator roll journalled in the frame so as to wipe against a portion of said transfer roll, a carriage longitudinally movable on said track beneath the applicator roll for moving work material into surface contact with said applicator roll, said applicator roll having a soft rubber-like face for applying viscous material to the work material and wiping said work material as it moves into treating position, and means for driving the transfer roll and the applicator roll in the sam`e direction of rotation.
