- DEVICE r03 FEEDING, BAGS Ann rnniirnn i Applioation filed February 26, 1917. Serial No. 151,076;

To all who'mz't may concern." ,7

Be it known that we, JULIAN S. JACOBS and JOHN RAYMOND, J12, citizens of the United States, and residents of'Springfield,

Vermont,.have invented certain new and.

materials used in the manufacture of shoddyi and also in themanufactureof paper.

Heretofore (it has been the practice in papermills or shoddy mills .to require the practically continuous attendance of an operator in feeding rags to the feeding apron or table of the picker in order to prevent the 7 rags from being fed into the machine in a rolled up or bunched condition. It has been suggested that a feed apron provided with spikes-or'projecting steel points for engaging the rags be employed for this purpose but attempts of this kind have not been satisfactory or'practical because of the fact that the means adopted-for releasing or disengaging the rags from the spikes have been uncertain and unreliable in their action.

The. present invention deals with this problem and comprises, generally speaking,

the combination of an endless carrier device or conveyer embraclng a serles of transverse slats provided with rows of automatically.

controlled points or spikes which during the feeding'part of the travel, project a sulficient distance beyond the face of the conveyer to engage and retain the'rags, and which are automatically withdrawn or disengaged from the rags at a predetermined point, with means for effecting the appropriate "move ment of the spikes or pointsso coordinated as to avoid the deflecting or thrusting of'the conveyer away from the normal line of its travel as will be hereinafter explained.

The invention consists in the combination with an endless conveyer of the transverse slats and cooperating spikes with their en-' gaging and controlling elements. It also consists in the details of construction of the transverse conveyer slats and the automati cally movableirows of spikes'arranged to act in the manner described. r

In the accompanying drawings We have illustrated the preferred arrangementlem- .Patented Mar. 5,1918.

bodying the principles of this invention Figure 1 is a side elevation of a feed de-.- I

vice or conveyer-provided witha'sufficient number of'the slats .and spikes to illustrate" the arrangementhereinafter described;

Fig. 2 is an enlarged detail vlew of an 1ndividual slat'combined with the spike-holda ing-member orbar. r

Figs 3 and 4c are end elevations of a sin-- gle slat and its spike supporting' element with the spikes in their protruding and their retracted positions, respectively.

. Fig. 5 is a plan view of one of the transverse spikes, in operative relation to the spike-protruding members or tracks.

' In the practice of our invention as illustrated in the drawings there are provided'a plurality of sprocket shafts a on which are mounted sprocket wheels at" over which pass parallel endless sprocket chains 0.? which are suitably spaced apart accordin'gto the de-' sired width ofthe feeding device.

To these sprocket chains of are secured a 7 series of transverse slats barranged asclose together as practicable. At each end, each slat bis provided with a perforation b for riveting or bolting the slat to the opposite links of the sprocket chains a Between the;

perforated end'portions each slat is provided with-a series'of holes 6 through which project a series of sharpened points of spikes- 0 that, according to the form of the invention illustrated in the drawings, are secured to a'bar or supporting member 0 which bar or supporting member is provided at each end with a long guidepin or finger '0 which passes through a guide hole 6 in the slat and also .through a hole-in the guide bracket or hook (I! which is secured to and supported by '95 the slat b.

It will be observed that when theslat is in a horizontal or even an approximately horizontal plane the weight of the supporting.

bar 0 will normally cause the spikes or points to drop through their respective openings 6 If the spike-supporting bar 0" is beneath the slat thenthe spikes 0 are retracted or withdrawn from the holes 1) I while if the spike-supporting bar is above beyond the normal plane or surface ofthe conveyer. The braoketsor guidei members 7 for thispurpose.

to keep the spikes in position to reenter their r appropriate holes after they have been 'withtend around the uppermost shaft a between i the sprocket jwheels thereon and are con-' take'member 1 Around the periphery of V the sprocket chains where they pass around drawn therefrom. i

The hopper w into which the rags are dumped is provided'with' a feed'belt'w at the point where the upward travel of the conveyer begins. It is necessary therefore that the spikes should protrude at this point and any convenient means may be provided We have shown in the drawingsa pair of parallel track members 0 arranged intermediate-of the ends of the slats-in close juxtaposition to the plane of upward travel of the sprocket chains so as to engage the spike-supporting bars 0 in such a manner as to thrust the spikes to their full extent up through the holes in the transverse slats of the conveyer; Thesetracks or spike-protruding members 6. ex-

tinued along in an approximately horizontal plane nearly to the next pair of sprocket wheels which are adjacent to the, picker inthe sprocket wheels adjacent tothe picker guides f arranged in the path of the u'pwardly projecting pins 0? so as to engage said pins and force them downwardly after gaging members or guides f are carried beyond and below the plane of the feeding in member y so as to make certain the withdrawal or retraction of the sharpened pins or spikes 0 to the inner side of or below the surface of their cooperating slats b. As soon as each successive pair of pins has passed below the lower ends of the guides f the weight ofthe spike bar 0' will act through the drop of the spike bar to return the individual row of spikes to their outward or protruding position in which position they remain during the downward travel of the slat to the lowest point of its travel. The tracker guide member e has its lower end turned back inside the line of travel of the slats around and beneath the lowermost shaft use as to maintain the. successively approaching rows of pins in their outward or projecting position ready to engage therags fed to them by the feeding belt w. i I a The laterally bent foot portion d ofthe bracket (Z serves as retaining stopsfor the spike bars when the spikes are completely withdrawn below the outer surface of their respective slats.

The guide members f are preferably formed at their npper'ends with upturned or sloping deflectingtongues f so 'as topro vide means for positively forcing down the feed are placed 7 two guard members or 2'' spike bars in case there isany 'tendency for them to remain in raised or pro ecting pos Y 3 tion through their frictional eng'ageiiieiit" with their respective 'slats', 5.
