HOWE, OF BUFFALO, AND SHERWOOD C. BLISS, OF KENMORE, NEW YORK, ASSIGNORS TO WEATHERIBEST STAINECD SHINGLE COMPANY, OF NORTH TONA- WANDA, NEW YORK, A CORPORATION OF NEW YORK 4 SHINGLE HANDLING MACHINE Application filed October 16, 1930. Serial No. 489,106.

Our machine relates in general to shingle handling machines and in particular to a machine for the feeding and brushing of stained shingles.

It is well known to those skilled in the art that in the process of drying stained shingles, bubbles are often formed on the surface,'which when dried, flake off, leaving the surface mottled and resulting in a shingle which is not uniformly stained. We have discovered that if shingles are brushed immediately after stained orsometime before they aredry, all such bubbles will be removed and the entire surface of the shingle will be uniformly stained. One of the drawbacks, however, to machine brushing of the'wet stained shingles has been'the difliculty in providing suitable means for handling the shingles during the operatlon.

The principal object of our invention has been, therefore, to provide means, whereby the wet shingles may be quickly and accurately fed to the brushing means,

Furthermore, it has been anobject to provide a device of this nature in which a tier of shingles may be fed at one time.

Moreover, our device provides efficient means for brushing the shingles on both sides thereof at the same time.

The above objects and advantageshave been accomplished by the device shown in the accompanying drawings, of which 1 Fig. llis a side elevation of our complete device.

Fig. 2 is a top face view thereof, portions thereof for clearness of illustration being omitted.

Fig. 3 is a transverse sectional view, taken on line 3-3 of Fig. 2.

Fig. 4 is an enlarged, fragmentary, sectional view, taken on line 4-4 of Fig. 2.

Fig. 5 is an enlarged, fragmentary, sectional view, taken on line 55 of Fig. 2.

' Our device comprises a base 10 which is preferably mounted upon .casters 11 so that it may be conveniently wheeled about. Carried by the base 10 is the framework of the device, consisting of vertical members 12 and inclined members 13. Arranged in interspaced relation with each of the inclined members 13 and projecting some above these members is'a guide plate .14, and between these plates is arranged a grating formed by a plurality ofinterspaced 7 bars 15. These bars are preferably inclined somewhat with respect to the guide plates 14, for purposes'to be hereinafter described and they are supported by suitable cross members 21 mounted upon angle iron members 22. Arranged above the bars 15' of the grating and near their lower ends is the hopper 16 of our device. This hopper has its back wall17 inclined at anangle as shown in Figs. 1 and 4, whereby a plurality of shingles 18 placed within the hopper will slide downwardly until their butts are in engagement with the back wall. Side walls 19 are provided for keeping the shingles in place, and-these side Walls are is slidable upon this plate and passes through the space formed between itan'd the bottom edge of the rear wall of the hopper. This feeder bar is designed to engage with the butts of the lowermost tier of shingles and to quickly-move them forwardly and upwardlyuntilthey pass by the upper edge of the rest plate 25 and fall onto the bars 15 of the grating. v I I The feed bar 26 is operated so as to have a quick forward movement which is sufficiently impactive to knock the lower tier of shingles from the hopper without feeding those which are on top of and supported by such lower tier. This mechanism comprises a cam 27 mounted at each side of the maeach of which engages with a pin 33 carried one at each end of the feeder bar 26, whereby when the feeder arms 29 are actuated, the bar will be operated thereby. The cams 27 have their surfaces so arranged that there is a gradual rise in the direction of rotation when the feeder arms 29 are being returned to their normal positions.

.The' surface of each cam, however, has an with the surface of the cam by means of a helical spring 36. Each spring is conveniently arranged on the side of the inclined members 13 and each is carried by an adjusting screw 37, wherebyits tension may be regulated.

Mounted at one end of themain shaft 28 is a sprocket wheel 40 which is connected by means of a suitable chain 41 to a gear reduction unit 42. This unit is driven by means of an electricmotor 43,. and a switch 44 is carried in a convenient position by one of the inclined members 13. Both the gear reduction unit 42 and motor 43 are preferably carried by an extension on the base 10, and these parts, for clearness of illustration, have-been omitted from Fig. 2. The sprocket wheel 40 is preferably mounted so that it is frictionally engaged with the drive shafts 28, in a well known manner, so that if the mechanism should be stalled for any reason, the sprocket :would slip and permit the motor to continue running until shut off by an attendant.

-Arranged nearrthe top of the machine is a feed drum 44 whichis mounted upon a drum shaft 45. Also mounted upon the drum shaft 45 are two sprockets 46, one varranged at each side of the drum and between the guide lates 14 and inclined members 13. The main drive shaft 28 also carries a sprocketwheel 47 at points between the guide plates 14 and inclined members 13, and connecting each of the sprocket wheels 47 and 46 is a feed chain 48. vA plurality of carrier bars 50 are secured to the chains 48 and extend across the machine and engage with the butt ends of the tiers of shingles which have been knocked out of the hopper. A stop plate 51 is arranged across the machine underneath the hopper and follows substantially the contour of the line of travel of the carrier-bars around the sprockets 47 whereby shingles which'have been knocked out of the hop er will slide down the bars 15 of the grating and be brought to rest by contact with this late until such time as a feed bar reaches them. The feed drum 44 Arranged between. the upperiend ofthe grating and the feed roller 44 are the brushes 60 and 61 of our device; These. brushes are of a length substantially equal to the width of the machine between the guide plates 14, and each of them is provided with the back plate 62 having its ends pivotally carried at one end by a link 63 and at the other end by a link 64. The links 63 and 64 are pivotally carried at points midway their lengthby means of brackets 65 which are secured to the inclined members 13. A brush cam 66 is carried at one end of the drum shaft 45, and the linkv63 is provided with a roller 67 for engagement with a groove 68 formed in the cam 66. This groove is formed so that the roller is caused to be moved: back and forth as the cam rotates, whereb the brushes willbe reciprocated in opposite directions back and forth across the upper and lower surfaces of each tier of shingles as they are being passed therebetween.

From the foregoing it will be clear that, when for instance, a batch of shingles is placed within the hopper 16 with their butt ends toward the rear wall 17, they will fall to the bottom of the hopper, resting upon the rest plate with their tips supported by the bars 15 of the grating. When the motor 43 is put into o eration, the feeder bar will be operated by the engagement of the lugs 35 of the feeder arms 29 with the curved surfaces of the cams 27 hen the camshave been rotated to a position where the lugs 35 pass the curved surfaces and reach the radially formed surfaces 34 of the cams, the arms will'be quicklv drawn upwardly by means of the springs 36, which will cause the feeder bar 26 to be brought against the butts of the lowermost tier of shingles of the bundle with. a sharp impact, thus knocking this tier of shingles forwardly to or slightly beyond the position shown in Fig. 4, where the butts will be at or beyond the forward edge of the rest plate 25 and from which osition they will fall onto the bars 15 of the grating and be in such a position that one of the carrier bars 50 will engage them and carry them upwardly along the bars 15. Should the tier of shingles which has just been discharged from'the hopper have a tendency to slide downwardly on top of the bars 15, they will be arrested in their downward movement by the stop plate '51. The tier of shingles which has just been ejected from the hopper will be carried upwardly along the top surfaces of the bars 15 of the grate and fed in between and through the brushes 60 and 61 where their surfaces will be brushed by the rec1procating movement of the brushes, thus removing any bubbles or blisters which may have formed on the surfaces of the shingles and giving to the shingles uniformly stained surfaces. Since the carrier bars are arranged in the same plane as the shingles being fed, they will pass between the brushes and carrv the shingles 011 up to the center of the drum ist. As the shingles are being discharged from the drum thev will be projected into a suitable hopper (not shown) arranged preferably immediately in front of and slightly below the drum.
