10 Claims.

My invention relates to a shingle painting and staining mechanism and my object is to provide a simple, inexpensive and emcient mechanism of this character for automatically applying paint,

I stain, or other liquid in a uniform manner to shingles.

In carrying out my invention I employ a relatively long housing and a conveyer for conducting the shingles through said housing. During passage of the shingles through the housing the paint or stain is applied to one or both sides, as preferred, of each shingle and then smoothed off to provide a uniform coating during which operation the surplus paint or stain is also removed.

Adjustable means are provided for exposing more or less of the area of the shingles to the action of the paint or stain applying means, so that, for instance, almost the entire area may be coated or only that portion may be coated which is to be exposed to the weather when the shingles are applied to a roof.

Means are also provided for thoroughly mixing the ingredients constituting the paint or stain while the mechanism is in operationso that the color may be uniform and all of the shingles will present the same appearance when coated.

Means are also provided for forcing the contents of the mixer to the paint or stain applying means and for collecting and returning the surplus paint or stain tothe mixer for reuse.

In order that the invention may be fully. understood, reference will now be had to the accompanying drawings, in which:

Fig. 10 is a detail perspective view of a shield which may be employed when the shingles are to be given variegated colors.

Fig. 11 is a fragmentary perspective view of a portion of the conveyer.

In carrying out the invention I employ a suitable housing 2 consisting in the present instance of a skeleton frame 4 inclosed in sheet metal or other 5 suitable walls 6. The housing 2 is mounted upon casters 5 so that it may be readily moved and its bottom portion is reinforced with a bed plate 4a to carry certain mechanism hereinafter described.

8 designates a conveyer comprising a pair of endless belts Ill each of which runs around a pair of pulleys l2 operably mounted upon the upper portion of thehousing 2. Thebelts l0 are arranged side by side and close together to frictionally en-, 15 gage and carry the shingles A from the front to the rear of the housing 2.

The belts l0 extend substantially the full length of the housing 2 and may be provided. with spurs [4, Fig. 11, to more reliably hold the shingles A from displacement during their progress through the housing 2. One of the belts I0 is driven by suitable mechanism and drives the companion belt by frictional contact with the intervening shingles A. The driving mechanism consists in the present instance, of a shaft [6 upon which one of the pulleys I2 is fixed, bevel gear wheels l8 and 20, pulleys 22 and 24, an endless belt 26 and a motor 28.

30 designates a guide for holding the upper edges of the shingles A in horizontal alinement 30 while passing through the housing 2. The guide 30 is adjustably supported above the housing 2 so that it may be raised or lowered to accommodate shingles of different lengths and also act as a gage in determining how large an area of each shingle is to be exposed to the paint or stain. The guide 30 is supported by studs 32 and nuts 33. The studs 32 are supported by brackets 34 secured to the top of the housing 2 and provided with longitudinal slots 36 to permit the studs 32, which project therethrough, to move up and down with the guide member 30 when the nuts 33 are loosened. As shown by Figs. 1 and 2 the forward end of the guide 30 projects beyond the front end of the housing 2 and cooperates with a short guide 38 in directing the shingles A through an inlet slot 40 in said front end. The guide 38, like the guide 30, is adjustable up and down to accommodate shingles of different lengths and for that purpose is secured to the housing by means of set screws 42 which extend through a vertical slot 44 in the guide 38. The rear wall of the housing is provided with an outlet slot (not shown) similar to the inlet slot 40 and communicating with the latter through a slot 56 extending longitudinally through the top of the housing 2 for the passage of the shingles.

The paint or stain is applied to the shingles A by suitable means such as a pair of oppositely disposed brushes 46 between which the shingles are adapted to pass edgewise as shown by Fig. 3. The brushes 46 are adjustably mounted so that they may be moved toward each other as the bristles 48 thereof are worn away by frictional contact with the shingles. The supporting means for each brush 46, consists, in the present instance of stud bolts 50 and nuts 52, which latter are threaded upon the former. The adjacent ends of the stud bolts 50 are-secured to angleirons 54 forming the upper longitudinal portion of the skeleton frame 4 and spaced apart to leave the intervening slot 56.

The brushes 46 are supplied with paint or stain from a suitable mixer 58 by means of a pump 60, a feed pipe 62 leading from the lower portion of the mixer 58 to the pump 60, and a pipe 64 leading from the pump 60 to'rlischargenozzles 66, all of which are located in. the housing 2. The nozzles 66 extend upwardly between the bristles 48 of the brushes 46, Fig. 6, and discharge against Spreaders 68 located at the upper portion of the brushes for directing the paint or stain downwardly over the bristles 48. The nozzles .66 are flexible so that they maybe moved towards or away from each other when the brushes 46 are adjusted upon the stud bolts 50 and one of the nozzles 66 is provided with a valve I0 for cutting off the paint or stain to the respective brush when it is desired to coat but one side of the shingles. The pump '60 is driven independently of the conveyor fl by suitable means such as a motor I2, sheaves I4 and '16and .a belt '86.

The feedpipe 62 is provided with a union 82 so that it may be uncoupled from thepump 60 when it is desired to swing the mixer 58 outwardly from the housing 2, Fig. '8, preparatory to supplying said mixer with paint or stainand so that it may beconveniently cleaned when desired. Before uncoupling the feed pipe-62 from the pump 60, a valve connected to said feed-pipe 62, may be closed to retain any paint or stain present in the mixer 58. In order that the mixer 58 may be readily swung outwardly or inwardly it is mounted upon hinges 86 and 88 and rails 90, which latter lead to an opening 92 in one side of the housing 2. The opening 92 is normally closed by a door 94 to exclude dust and other foreign matter from the interior of the housing '2. The door 94 is connected to the housing by a hinge 9650 that said door may be swung upwardly out of the way when opened.

The mixer 58 isequipped with a shaft 88 provided with an agitator I 00 for mixing the ingredients constituting the paint or stain. The shaft-98 is drivenindependently of the conveyor "8'and the pump 60 by a motor I02, gear wheels I04 and I06, a shaft I08 and gear wheels 0 and H2. As shown the foregoing driving mechanism is mounted upon the mixer 58 to swing outwardly or inwardly therewith so that the agitator I00 may be driven while the mixer is in either position. The gear wheel I I2 is secured to the agitator shaft 98 by means of a set screw H6 so that said gear wheel maybelifted from said shaft when it-is desired to remove the lid II4 from the mixer-58 preparatory to filling or cleaning out the latter.

After a coat-of paint or stain-has been applied to one or both sides of the shingles A by the brushes-46, it is smoothed off to approximately uniform thickness and the surplus-paint or stain is removed by a plurality of brushes I20 spaced a suitable distance to the rear of the brushes 46. The brushes I20 are somewhat similar to the brushes 46, excepting that they are arranged at an angle to the shingles instead of parallel therewith. The brushes I20 are adjustably connected to the angle irons 54 by studs I22 and nuts I24 so that said brushes may be adjusted toward each other as the bristles become worn.

The surplus paint or stain dripping from the shingles A and the brushes 46 and I20 falls into troughs I 26 and I 28 which slope downwardly from the ends of the housing 2 to a spout I30, which :latterudischarges the surplus paint or stain into the. mixer 58 for reuse through an opening I32 in the lid II4. The entrances to the spout I30 and the opening I32 have screens I34 and I36, respectively, to catch any splinters or other foreign matter removed from the shingles by the brushes 46 and I26. The troughs I26 and I28 areqnearly' as wide as the interior of the housing 2. to catch the surplus paint or stain and prevent it-from-splashiing upon the mechanism located in the lower portion of the housingZ.

In eorderto enhance the appearance it is sometimes desirable to apply a variegated color to that portion of each shingle which-is to be exposed to the weather when the shingle is laid upon.:a roof. The variegated color is obtained by applyingpaint of one color to the shingles with the brushes .46 and then spraying-paint of another color ,by suitable means notshown, over the first coat of paint .as the shingles travel behind a shield" I38 which is suspended in the rear. part of thehousingby stud bolts-l40 projecting from the adjacent angle iron 54. The shield I38 prevents wastage of the sprayed paint as it is of such size asto cover all but that portion which is-exposed to the weather when the shingles are laid upon the roof.

Briefly stated the operation is as follows: The shingles A are placed one by one between the guides30 and 38 and then pushed between the belts I0 of the conveyor 8 which carries the shingles to the rear end of the housing'Z. In their passage through the housing the shingles are coated with paint or stain suppliedeto one or both of the brushes 46, as preferred, by. the pump 60 which draws the paint orstain from the mixer 56 through the pipe62 and forces it-to one or both brushes 46 through the pipe 64 and the nozzles 66. Some of the surplus paint or stain drips from the shingles into the trough I26 which conducts it back to the mixer '58: for reuse. As the shingles pass between the brushes I 20 the paint or stain is smoothed uniformly upon the surface of the shingles and more of the surplus paint or stain isbrushed off .and falls into the troughs I26 and I28 which conduct it back to the mixer 58. As the coated shingles are discharged from the rear :end of the housing 2 by the conveyer 8, means are provided for receiving said shingles-but since such means forms-no part of the present invention it was not-deemed necessary toshow or describe the same.

When the guide :30 is loweredthe shingles A are also lowered as they pass'through the housing :2, so that more of their surface is exposed to the brushes 46, and whensaid guide is raised the shingles pass through the-housing on a higher plane so that less of their surface will contact the brushes 46. 7
