My invention relates to a fee "ling rack that is especially designed for i use in connection with flat newspaper baling machines and the principal object of my invention is, to provide 5 a relatively simple, practical and inexpensive rack that will receive and hold a pile or stack of flat laid newspapers and which rack, when manipulated, will quickly feed or deposit the stack of papers into th e compression chamber of a newspaper baling machine.

Further objects of my invention are, to generally improve upon and simplifythe constructionol the existing forms of newspaper:

feeding raclrs'further to construct the rack so that it may be conveniently handled and manipulated by a single operator, and fur ther, to construct the rack so that it may be conveniently moved from one point to another and shifted towar d and'away from the balin machine durin the transfer of a ile D b r of newspapers from th e rack into the comression chamber of the bale machine. 7

W 1th the foregoing and other ob ects 1n view, my nvention consists n certain novel features (if-construction and arrangement of parts that will hereinafter be more-fully'described and claimed and illustrated in the accompa nying drawings, in which: Fig. 1 1s a vertical section taken e center of a leedlng rack constructed'in through accordancewith my invention and showing the same in position t papers.

Fig. 5 is ahorizont 66 of Fig; 3.

Referring by numera mately on tho'line 44 of Fig. 3.

al section taken am Fig 3.

ls to I the accompanyc-f these sliding railsare vertically ing drawings, which illustrate a practical embodiment of nay-invention, 10, 10 designate the side railsof the base frame of the rack, the rear ends of which side rails are connect-' ed by an end rail 11 and the forward ends of said side railsaresupported upon an axle l2 and onrnaled-upon the ends of, the latter are J small wheels 13. v

One end of axle 12 is mounted in a bearing plate 13 that is mounted'forvertical sliding movement in a bracket 13 and the vertical position of which bearingplate is regulated by a set screw 13 that is screw seated in the upper portion of the bracket and which bears on top of plate 13* (see Figs. 3 and 6.)

Secured to the rear ends ofthe side rails 10 are the lower ends of upright members 14 and [secured to and projecting forwardly frorn'the upper portions ofsaid uprights are handrails 15, the forward portions of which extend downward and their lower ends are rigidly securedto the forward portions of side rails 10. I

Theupper portions of the uprights 14' and the rear portions of hand rails 15 are manually engaged by an operator while the rack is being moved from one position to another.

Arranged beneath the rear ends of the side rails 10 of the base'frame are castor wheels 16.

Arranged to slide freely on the upper edges 7 of the side rails 10 are the base rails 17 of asliding frame-and formed integral with and projecting upwardly from theifor ward ends disposed plates or panels 18, preferably formed of sheet metal and which function as the side walls of the rack that receives thepiles or stacks of paper.

Rigidly secured to the upper portions of these side wall plates 18 are the upper ends of braces 19, which" extend downwardly and rearwardlyand the lower ends of said braces are'secured to the rear ends of the sliding rails17Q p p The ends of a horizontally disposed rod 20 are supported in hearings on the upper portions of the braces 19'and loosely mounted onthe central portion of this r'od is' the forward end of a hand lever 21 that projects rear portions of hand rails 15 and formed integral with and projecting downwardly and rearwardly from the forward end of this hand lever is a crank arm 22.

Arranged to move freely between the side Walls or plates 18 is an upright plate 23, preferably of sheet metal and projecting from the rear face thereof near its center is a web or plate 24. Pivotally secured to the lower portion of this web 24 is the forward end of a rod 25 and the rear end of this rod is pivot ally connected to the lower end of crank arm 22.

Pivotally mounted on the forward portion of hand lever 21 is a bell crank shaped hook 26 and a notch 27 in the forward end thereof is adapted to engage a rod 28 that has its ends seated in the rear portions of side walls 18 nearer the upper ends thereof. The short arm of this hook 26 is connected by a rod 29 to a short hand lever 30 that is pivotally mounted on the rear end of hand lever 21.

Pivotally secured to the lower ends of the uprights 14 are upwardly and, forwardly projecting tubes 31 and arranged for sliding movement in the upper portion of said tubes are rods 32. the upper ends of which are pivotally connected to ears that project rearwardly from plate 23. V j

Adjustably mounted on the projecting portion of rod 32 is a collar 33 which may be locked to said rod by a set screw 34 and projecting from said collar downwardly and rearwardly is a bar 35 to the collar and of which is secured a ring or collar 36 that passes around tube 31.

Adjustably mounted on tube 31 ashort distance in front of the ring 36 is a collar 37 that is locked to the tube by means of a set screw 33 and this collar serves to limit the upper movement of ring 36 on the tube 31 and consequently limiting the forward and upper movement of rod 32 relatively to said tube.

Arranged between the forward portions of sliding rails 17 but not connected thereto, is an an 'le bar 39 to the lower flange of which is secured the lower ends of a series of rods 40 and said rods project forwardly through apertures 41 formed in the lower portion of plate 23. These rods 40 function as rests upon which the papers are piled to form the stack in the feeder.

Pivotall r connected to ears that are mounted to the ends of angle bar 39 are the forward ends of links 42 and the rear ends of said links are pivotally connected to the intermediate portions of sliding bars 17.

Secured to the central portion of angle bar 39 is the lower end of a retractile spring 43 and the upper end of this spring is secured to a cross rod 44 that extends between the rear lower portions of plates 18. This spring normally exerts upward pull on cross bar 39 and the parts connected thereto.

Pivotally connected to the central portion of cross bar 39 is the lower end of an upwardly projecting rod 45 and the upper end of this rod is pivotally connected to a link 46 and the latter being loosely mounted on cross rod 20.

Fixed on the front side of the upper portion'of rod 45 is a bracket 45 that projects a short distance above the pivot point between said rod and the link 46 and seated in said bracket 45 is a set screw 45* that functions as an adjustable stop for limiting the swinging movement of link 46 and the upper end of rod 45 in one direction.

In other words this adjustable set screw prevents the pivot between rod 45 and link 46 from moving past center rearwardly and when the parts occupy the positions as illus trated in Fig. 2 the forward portions of the paper supporting fingers or rods 40 may swing downward so as to clear the underside of the pile of papers that has been deposited onto the pressure head within the baling chamber.

By thus permitting the rods 40 to swing vertically when the pile of papers has been deposited in the pressure chamber there is no tendency of the rods to drag on the underside of the pile of papers and disturb same or pull the lowermost papers from beneath the pile while the rods are being withdrawn from the baling chamber.

Secured to the upper portion of web and projecting rearwar therefrom is a finger 47 which functions as a stop to limit the swinging movement of the upper end of rod 45 toward plate 23.

In the use of my improved feed hand lever 21 is swung upward and is manipulated so to cause notch l forward end hook 26 to engage rod 2 and when hand lever is thus positioned plate 23, fingers 40 and the various pi nections occupy the positions lllllsti'ztfil in Fig. l with plate 23 in a sh "h 'ly inclined po sition and with fingers 4O inclined so that their forward ends are @lGTfLtBCl with respect to their rear ends.

The upper portion of rod bears against stop 47 and as link 46 bears against the adjustable stop 45* said rod and l' 1k occupy the 1, with the 11 rated in r 1g. result that the rail 39 is held its lowermost positions as illust limit of movement u it the foremost ends of the rods or fingers 4O slightly elevated.

A stack of papers is now placed on the lin gers 40 with the rear edges of the papers bearing against inclined plate 23 and the ends ofthe papers g the side walls or plates 18.

the stack papers occupies a subwithdrawn a snort di stack of papers into the pressure chamber of the baling machine. v An operator manually en agesthe rear ends ofhand rails and moves the loaded rack toward the baling' machine so that the stack of papers, the side walls 18 and the fin gers 40 that support the stack enter the balk ing chamb and the operator now presses the small hand lever 80 toward the rear end ofhand lever 21, thereby disengaging hook 26 from rod 28.

The combined weight of the stack of papers on the fingers 40, together. with the upward pull exerted by retractile spring 43 now swims the fingers 40 into a substantially horizontal position, as illustrated in. 2 and the upward movement of rod 45 hearing against stop 1.5 r l? will exert pressure thereon so as to swing plate 2-3 into a vertical position durin which-movement rod 32is .nce from tube 31 until ring 36 engages'against stop collar 37.

Thus thestaclr of papers is delivered into the pressure chamber of the baling machine j and to withdraw the side plates 18 and lingers 40 from their positions to the sides ant-Li beneath the stack, the operator moves the rear end of hand'lever Ql' llOYVIUVELIQllY with that plate 23, which is now in the vertical po ion, as illustrated in Fig. 2, will bear again the stack of papers and the pres sure applied to the rear end of the lever will react through rod 25, arm 22 and rod to cause the sliding frame comprising base rails 17, sideplates l8 and braces 19 to move rearwardly until the front edges of the side plat-es 18ers in practical transverse alignment w' t plate 23 and the forward ends of the rods have been withdrawn through as apertu s ll until all parts of tho sliding me occupy the positions as illustrated in he pivotal connection between the rod and linlr l6 permit said rod 45 to move upwardly a short distance, thus loweringthe forward ends of the rod 40 so that they will not engage and drag upon the underside of this stack of papers as they are being withdrawn from position beneath said stack.

The rack is now withdrawn from the balic machine and hand lever 21 is swung up-.

wardl thereby restorin the various movin 1 l s b #11 parts of the rack to their originalor normal positions is illustrated in Fig. l and hook 26 is.

thereby loclrmanipulated to engage roe no, ing the parts of the rack in their normal positions. v 7

One of the wheels 13 is made vertically adjustable so that one side of the rack may be raised or lowered to adjust the vertical positions of the side plates .18 relative tothe'pressure chamber in the press and to compensate for any irregularity on that portion of the floor immediately in front of the press and over which the rack is moved while deliverhand i ing stacks of papers into the pressure ch amber.
