aoromrrc 1APEB-FEEDER3 Specification of Letters Patent. Patented Mar, 1; 1910, Originalsppltcstion filed December), 1908, Serial No. 468,384. Divided and this application filed j September .8, 1909. Serial No. 516,759.

To all whom it may concern:

Be it known that I, Josnrn Hams, a citizen of the United States, residing at Brooklvn, in the county of New York-and State of New York, haveinvented new and useful ive feed of paper or sheets is automatically arrested.

Other features of the invention having been set forth in my application Ser. No. 468,34 ofwhich the present application is. a division need not be specifically mentioned herein.

This invention is set forth in the following specification and claim and illustrated in the annexed drawin in which Figure 1 showsa p an view of .a paper feeder embodying this invention. Fig. 2 shows'a side elevation of Fig. 1, looking from theleft. Fig. 3 shows a view of- Fig. 1 looking from the left. Fig.4 is a section along line age: Fig. 1. i

In this drawing the automatic paper feeder isshown com rising aframe or. support a with a table adapted to support a pile of sheets 0. This table can be lifted by a screw' stem'd having miter gear connection c with ratchet wheel 1. The ratchet wheel is actuated by a sawl 9 Fig. 2 pivoted on'pawl arm h actuate by a link i and crank pin is on rotating shaft m. When the pile c rises beyond a'certain level the finger. 0 on lever p swings the latter and the rock shaft 9 to which it is secured, said rock shaft carrying an intermediate lever r. A stop lever sis pivoted at t and the free end of this stop 8 rests on the lever 1' or m a channeled or I sunken portion of lever 1' so as not to normally project above the top edge of lever r.-

A catch 2 on. arm k can then slide back and forth on-the lever r as the pawl arm h is swung back and forth by link 2'. When the lever r is raised by the rising sheet ile. swinging up the lever p the stop a is ti ted u ward to o lever r 1g. 3. The catch'2 now swingp roject its-free end above the face 1 ing against the stop 8 will arrest the movement of the pawl arm and its pawl g. The

pawl arm is loosely connected to link i so that the lmk can move when the pawl arm is arrested. A pin and slot connection can serve for loosely connecting the link and pawl arm. As the sheet pile diminishes the lever p with intermediate lever r sinks to allow stop 8 to drop clear of the .catch 2 when the pawl 9 can then begin to actuate the wheel f to raise the sheet table. The arm h if leftfree will swing or oscillate by its wei ht and if in the position of'the .parts shown in Fig. 2 the link 2' moves to theright it will pull arm h to the ri ht, and as the link 2' returns the arm hwifi oscillate back again unless-the swing of arm h to the left is arrested by catch 2 striking stop 8. The sheet adhering to the rim of wheel 5 is carried forward to be taken off by roller 6 between which and roller 7 the sheet is carried off. The mouth piece {connects with a suction tube 6 but as the pneumatic a'rrange- P ment is already set forth in said previous application no specific 'mention thereof 1s necessary here. I

The mam shaft on can be actuated 1n any suitable way and can be provided with fast and loose pulleys. The sheet table I) can be set by hand to any desired level when starting the machine. The shaft of ratchet wheel f can have a handcrank 27.

What I claim is The combination, in-a paper feeder, of a sheet support; mechanism for elevating the same including a movable member provided with a catch; a lever; a movable stop havin an d means actuated by the supply of sheets upon said supportfor rocking said lever, to raise said stop end'into position to engage said catch.
