BRANNING-MACHINE Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed March 29. 1906. Serial No. 308,819.

To all whom it may concern:

Be it known that I, JAMES W. BRYSON, or New Castle, in the county of Lawrence and State of Pennsylvania, have invented a new and useful Branning-Machine, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a sectional end elevation of my improved apparatus; Figs. 2 and 3 are end elevations showing opposite ends; and Fig. 4 is a side elevation, with parts removed.

Hy invention relates to that class of branners or plate cleaning apparatus wherein the sheets or plates are fed upwardly through the bran or cleaning material.

The object of the invention is to provide a cheap, simple and effective feeding mechanism which will introduce and start the plates upwardly through the branner without the use of skilled labor. 7

In the drawings, 2 represents a branner case, having stationary end- plates 3, 3; the side plates 2 are preferably removable and are held between guide-strips on the end-plates as shown in Fig. 1.

The bottom of the receptacle consists of curved plates 4, 4 with their inner adjacent edges spaced apart and provided with angles 5, 5, whose flanges project upwardly and inwardly toward each other. The angles are preferably adjusted so as to allow passage of the plate up between them by leaving a narrow slot between their edges. Below the angles 5 are driven feed-rollers 6, 6, preferably having separate adjustable roller portions 7,

1, as shown in Fig. 4. Above the inlet slot are provided guide lingers 8, 8 which lead to feed-rollers 9, S), above which the guide fingers 10, 10 lead to the feed-out rollers 11, 11. The form of these rollers is preferably as shown in Fig. 4. Above the rollers 11 is a deflector 12 which curves the plate over so that it drops and slides down the chute 13. Below the feed-in rollers G, 6, are stationary vertically extending guides 14, against which the upper end of the sheet slides as it is forced up into the bite of the feedrolls.

The sheets to be cleaned are fed in upon the swinging rest bars 15, having the supporting ledges or hooks 16 at their lower ends. These rest bars are secured to a transverse supporting-bar 17, which is pivoted at its ends and rests upon the adjustable blocks 18. These blocks, at each end, are provided with screw-threaded holes engaged by screw-spindles 19, having bevel gear connection 20 with the shaft 21, having an adjusting wheel 22 at each end. The blocks 18 are guided between the slotted standards 23; and by turning the hand-wheel the position of the bearings may be adjusted. A slotted lever 24 projects from the bar 17, its slot being engaged by a pin projecting from a vertical slide 25.' This slide moves through suitable 1 guides 26 and carries at its upper end an internal cam 27. The cam 27 is engaged by a crank-arm 28, projecting from driven shaft 29.

In the form shown, 30 is the main shaft receiving power through the pulley 31. At its opposite end shaft 30 is provided with a sprocket wheel 32 which receives a sprocket chain extending over the sprocket wheels 33, 34 and 35, as shown in Fig. 2, by the dia grammatic line. Each of the shafts 6, 36 and 37 is provided with a pinion inter-meshing with a correspending pinion on the other shaft of each pair, thus driving the feed-in rolls and the rolls 9 and 11. At the belt pulley end one of the shafts 6 is provided with a sprocket-wheel 38 from which a chain extends over sprocket wheel 39 on the shaft 29.

The shafts of the heaters 40 which stir up the cleaning material are connected by pinions 4], and one of these shafts is provided with a sprocket wheel 42 having sprocket-chain connection with a sprocket wheel 43 on the main shaft 30.

In using the apparatus the slide 25 reciprocates continuously and thereby tilts the rest-bars backwardly and forwardly. When the slide is moved down the rest-bars assume the dotted line position shown in Fig. 1; and the sheet is then inserted by the attendant. As the slide 25 then rises the rest-bars will be tilted forwardly into position shown in full lines in Fig. 1, thus throwing the upper end of the sheet over against the stationary guides 14. On the next lowering movement of the slide 25 the rest-bars tilt back, thus raising their lower ends and forcing the sheet upwardly until its upper end is engaged by the feed-rolls 6. The operator then inserts the next sheet, the rest-bars are tilted forwardly and the operations thus go on continuously. Each sheet is successively fed up through the bran between the feed-rolls and fingers and then drops upon the chute.

The advantages of my invention result from the automatic feeding of the sheets upwardly through the bottom slot in the cleaning machine. The operator simply drops the sheets one after the other into the rest-bar receiver when in tilted-out position, and the machine then throws over the sheet and feeds it upwardly. The apparatus is simple and not liable to get out of order; and may be cheaply made and installed.

Variations may be made in the form and arrangement of the cleaning machine and the feed-mechanism without departing from my invention.

I claim 10 5 1. A sheet-cleaning machine having a lower entrance opening, vertically arranged guiding means below the said opening, and an oscillating feeding receptacle arranged to receive the sheets in inclined position and then tilt their upper edges against the guiding means, said feeder being also arranged to raise said sheet during its backward movement: substantially as described.

2. A sheet-cleaning machine, having a lower entrance opening, a pair of feed rollers below said opening, a guide device below the feed rollers, an oscillating feeder receptacle, having a portion adapted to tilt the sheet in onedirection of. its movement, and to raise the sheet to the bite of said rolls by its opposite movement, and means for actuating the receptacle; substantially as described.

3. In a sheet-cleaning machine, an oscillating feeding receptacle, arranged to receive a sheet in inclined position and to tilt the sheet in one direction of its movement, and to raise the sheet during its opposite movement, and means for actuating the receptacle; substantially as described.

4; In a sheet-cleaning machine, a pivoted feeding receptacle having a sheet-support below its pivot, and means for oscillating said receptacle, substantially as described.

5. In a sheet-cleaning machine, a pivoted feeding receptacle, means for oscillating said receptacle, and means for adjusting the pivotal point of said receptacle; substantially as described.

6. In a sheet-cleaning machine, a feeding receptacle, consisting of a plurality of pivoted rest-bars having sheet supports at their lower portions below their pivots, and means for oscillating said bars in unison; substantially as described.

7. In a sheet-cleaning machine, a feeding receptacle, consisting of a plurality of rest-bars having sheet-supports at their lower ends, a fulcrum bar connecting the rest-bars above their sheet-supports, and vertically adjustable bearings for the fulcrum bar; substantially as described.

8. In a sheet-feeding machine, having a lower feed-in opening, a vertical sheet guide below the said opening, and a tilting feeder receptacle arranged to first tilt the upper edge of a sheet against the said guide and subsequently to raise the sheet; substantially as described.

In testimony whereof, I have hereunto set my hand.
