Shown in ih@ C mmm wfvew mil movement of the upright arm q' is suon that the retaining-finger strikes the pile beforethe upright arm completes its backward movement, whereby the' spring g5 is strained 'during the last portion of this movement. During the rst portion of the forward movement of the upright arm the latter moves inde pendent of the retaining-finger and shifting rod until the armengages with the front'collar g8, when the retaining-finger is raised from the pile during the last portion of the forward movement of the upright arm. By this means the retaining-finger is lowered upon the pile duri-ng the first portion of the upward movement of the com b-wheel and held down on the pile until the last portion of the downward movement of the comb-wheel, thereby preventing displacement of the uppermost sheets of the pile.l

'lhe pile-retaining fingers can be shifted ontheir supporting-sleeves for adjusting them transversely to sheets of different' widths, For the purpose of permitting the pile-retaining fingers to be adjusted to sheets of different lengths the transverse rod p2, supporting the fingers, is made adjustable lengthwise of the machine.' This adjustment is effected by means of two gear-pinions r i', mounted near opposite en'ds of the supporting-rod. p2 and meshing with longitudinal gear-racks i" 1",Varranged on the inner sides of the side frames Upon turning thewsupporting-rod in either direction it is compelled to move bodily backward or forward by reason of its pinions rolling over the racks. The pinions are held in mesh with the racks by extending the ends of the supporting-rod throughhorizontal slotsr2 v"-"in the side frames, and the supporting- I rod is held in its adj usted position by any suitable means*for instance, by a clamping scrcwnut r3, arranged upon the screw-threaded end of the supporting-rod and bearing against the outer side of the adjacent side piece.` When the rod supporting the pile-retaining lingers is adj usted backward or forward, the collars Q3 q* are correspondingly adjusted on the rod Q.

It has been found in practice that 'thin sheets of paper respond more readily to the feeding and"separating action of the combwheels than thick sheets of paper. This causes thin sheets` to be combed out farther than thick sheets by the same number of turns of the comb-wheels. In order to adapt themachinefor feeding sheets of paper of different thicknesses, the pile-supporting table is made longitudinally movable o n its su pporting-frame, so that the pile of sheets can be adjusted toward and from the deliveryrollers. This adjustmentis effected by means of a transverse shaft s, journaled in the table-supporting frame and provided with gear-l 1 pinions s s', meshing with longitudinal gearracks `s2 e2 on the under side of the pile-supporting table, and a crank-shaft s3, journaled onthe` pile-supporting frame-.and provided with a Worin s4, meshing with a worm-wheel :f5 on the 'shaft s. When feeding thick paper,

i sedans :the pile-table is moved forwardly-g so that a given number of turns of the comb-Wheels will carrythe sheets from the pile to the delivery-rollers. f' When feeding thin paper, the pile-table is moved rearwardly, so that the same number of turns ofthe comb-wheels will not feed' the sheets too rapidly to the deliv-l ery-rollers.. l

The upper portion of each front paper-guide D passes through a bracket t, secured to the front end of the pile-table, and the lower end of this guide is provided with a 'horizontal slotted foot which receives a screw t2, secured to the frame. lThis means of supporting the front guide always retains the latter in its proper position with reference to the pile-table and also permits the latter to move vertically for feeding the pile to the combwheels and alsolengthwise for adjusting the table to the kind of paper which is to be fed.

The operation of my improved paper-feeding machine, briefly stated, is as follows: When starting to feed from the top of an uncombed or new pile of sheets, the front edges of the sheets may be so far from the deliveryrollers that the comb-wheels descend several I times upon the pile before'the upper sheets of the pile have been eoxnbed'out suliciently to carry the top sheet to the delivery-rollers. During this operation the cams h h drop the comb-wheels upon the pile when the upper delivery-rollers rise and raise the comb-wheels when these rollers descend. When no sheet has been carried to the delivery-rollers before the upper delivery-rollers descend, the combwheels are raised solely -by the cams 7i Without the aid ofthe variable lifting mechanisms which are controlled by the trip-pawls and sheet. The upper portion of the pile is thus combed out intermittently untilthe top sheet reaches the delivery-rollers, when the normal operation of the machine begins and the uppermost sheets are thereafter fed successively to the delivery-rollers. As the top sheet is fed forwardly by the comb-wheels to the delivery-rollers the upper rollers are in their elevated position and the front edge of the advancing sheet engages under the lower arms of the trip-pawls and lifts, the same; thereby engaging the upperarmsthereof with the ratchet-wheels and effecting the lifting of the comb-wheels and the interruption of their feeding action in-the manner hereinbefore described. Irene side of the sheet reaches .the delivery-rollers in advance of the other side, the trip-pawl on the advancing side of the sheet willhe operated first and -s`top`the operation of its companion comb-wheel, while the comb-Wheel on the trailing side of, the sheet will continue to operate until that side of the sheet also reaches the delivery-rollers, when the trip-parti on the trailing side of the sheet will also arrest the operation of its companion' comb wheel. The upper deliveryrollers now drop upon the sheet resting on the lower rollers and remove the sheet from the pile." .lust before the upper delivery- Zi Ji 4.
