MACHINE FOR FEEDING OR GATHERING SHEETS, SIGNATURES, &c.

SPECIFICATION forming part of Letters Patent No. 672,761. dated April 23, 1901.

Application filed September 20, 1900. Serial No. 30,608. (No model.)

To all whom it may concern:

Be it known that I, EUGENE F. GOODMAN, a citizen of the United States,residing at Manhattan borough, in the city, county, and State of New York, have invented new and useful Improvements in Machines for Feeding or Gathering Sheets, Signatures, and the Like, of which the following is a specification.

This invention relates to so-called sheet feeding or gathering machines, and the invention resides in the novel features of construction set forth in the following specification and claims, and illustrated in the annexed drawings, in which Figure 1 is a plan view of the machine embodying this invention. Fig. 2 is a section along w w, Fig. 1. Fig. 3 is aside elevation of Fig. 1. Fig. 4 is a section along 00 00, Fig. 1. Fig. 5 is a section along g y, Fig. 1. Fig. 6 is a detail view of a shaft with clutch. Figs. 7 and 8 show different positions of a valve. Fig. 9 shows a modification.

A base or support comprises legs a, carrying side pieces a, in which a sheetsupport or boardb can be raised and lowered. This sup port is shown in Fig. 4 with a supply 0 of sheets or signatures. The top sheet or signature is lifted or fed off the pile by what is commonly known as a suction-tube 1 and which has a feeding or four-motion stroke. When this feeder tube drops onto the top sheet, the latter adheres or is sucked to such tube and is raised off the pile on the rise of such feeder. As this feeder 1 now moves forward or toward the gathering device or apron g the top sheet is carried forward or fed between the rollers f, by Which such top sheet is fed outward or onto such apron. The exhaust or suction in tube 1 being cut off or temporarily interrupted,ashereinafter explained, the sheet is released by the tube and is free to be carried entirely out or forward by rollers f. The tube 1 returning and dropping onto the next succeeding sheet of the pile will raise or feed the latter in its turn, and so on.

The feeder is carried by bar 2, Fig. 4, hav ing a rear or forked portion i, sitting about the driving-shaft 7c,and its front portion resting on cam Z on shaft m. The shaft 70 has cam 97., acting against roller 0, Fig. 4, on rod 11 to give the forward or feed motion to the feeder. The spring 19 retracts the feeder after it has fed. The cam Z causes the feeder to rise and allows it to fall when to contact with or feed a sheet.

The spring p can be suitably hitched, as to a shaft g, on risers r, secured to side pieces a. The shaft q can be rocked by a handle q, for a purpose presently explained.

The detent e is carried by shaft 6, rocked by cam 8, Fig. 1, on shaft 70. This detentarm 6 acts as a sort of auxiliary to feeder 1, as it insures the latter feeding only one sheet or signature at a time. This arm e presses on the top signature at a suitable distance from the feeder as the latter sucks or bends up a corner portion of the top sheet. Should the next underlying sheet have a tendency to adhere to the top sheet, the corner portions of these sheets as the feeder sucks up or raises will spring apart or separate. The detent c then rising will leave the entire top signature free to rise or strip off the underlying signature or pile on the continued rise and forward stroke of the feeder. The free or pile-pressing end of detent 6 could have a roller applied to allow the top sheet to move laterally a certain extent on the rise of the feeder, thus reducing friction and lessening the strain on the suction.

The shaft k is driven by any suitable means.

In the drawings is shown a pulley or wheel 12, which can have a crank, belt, or other driving means. This pulley has also a belt or connect-ion 14 for driving the shaft of the lower feed-rollers f. The upper rollersfon 15, along which travel the wheels or guiderollers 16 on side pieces I) as the board I) rises or falls.

In the drawings are shown two endless chains 17. Each chain has a branch secured to the holder or board 17 or its side pieces 19.

member 33 causes rotation of the shaft.

pulley 36 connects by belt 37 with crank or hand wheel 33, so that the board 19 can be The chains are guided about pulleys on the lower shaft 18 and on the upper shaft 19, Figs. 1 and 3. The upper shaft has a ratchet 20, Fig. 5,- and the locking-pawl 21 when engaging the ratchet prevents retrograde rotation of the same, so that the board I) cannot fail or sink. This pawl 21 does not, however, prevent the rise or upward feeding of board I). The holding-pawl 21 can be withdrawn or freed to allow the board I) to sink or lower when required. The cord or connection 22 extends from pawl 21 to rock or winding shaft q, Fig. 5, and when by handle q this shaft is suitably turned to wind up the connection 22 and cause the latter to free or withdraw the locking-pawl the board b is free to lower.

The upward feed of the board b is edected by pawl 23 rotating ratchet 2O. This feedpawl 23 is pivoted at 24 to arm 25, Fig. 5, which rises and'falls as the cam 26 is rotated by shaft is. The pawl-pivot 24 has fixed thereto a releasing-arm 27, which is shown so overweighted that at intervals it rises as the bar '11 lifts, and thus swings pawl 23 out of gear, while when the pawl is to feed the arm *5, dropping onto the low part of its cam Z, causes arm 27 to swing down for pawl 23 to move into action when the paper or pile c is too low.

While arm 1' is raised and feeder l is feeding out a sheet, the pawl 23, being held out of action, will not disturb or raise the board or pile.

The arm or wire 27 is shown in the modification in Fig. 9 with its lower or free end descending to the pile, and should the latter be lifted to or above the required level such pile will have lifted arm'27 to hold pawl 23 out of action until the pile has been suitably diminished or lowered. The arm orlifter27 can then sink to allow pawl 23 to move into gear. By either arrangement the feed of board I) by pawl 23 can be temporarily interru pted.

The shaft 18, Fig. 6, has a clutch member 30, which when engaged by driving clutch The raised or lowered by hand when clutch 33 is locked and looking-pawl 21 is freed.

From shaft It extends a belt 39, Fig. l, to pulley 42 of gathering-apron g. This apron can travel or be extended along indefinitelyin front of a series of machines or boards I) to gather sheets or signatures coming from said several machines. The shaft 18 can also extend across or connect with a series of machines. V

The shaft 722, Fig. 3, can be driven from shaft 70 by belt or connection 43.

An arm 50 has adjustably connected thereto an arm 51, to which is connected roller 53. A sheet fed from rollers f will be stopped by roller 53 from going too far forward.

The retractor or winding-shaft (1, it may be noted, can be extended indefinitely across a series of machines or supports 1), so as to form a release common to a number of holdingpawls 21. To release an individual pawl 21, in each case its chain or connection 22 can be pulled while shaft q is left at rest. support I) can thus be lowered by itself or a series of supports lowered simultaneously.

In mentioning belts, as 14 39, it is understood that sprocket-chains and corresponding pulleys or'gears are included and have been found advantageous in practice as preventing slipping or lost'motion.

The sheet-holderb, as noted,.will d rop when pawl 21 is released. To ease orslow the drop or descent of this holder or support, a piston 54, Fig. 2, and cylinder 55 are applied, forming what may be called an air-cushion or spring. To allow the compressed air in the cylinder to escape with suitable slowness, a

vent or nipple 56 has been found practical.

The suction-tube 1 has a hose or flexible connection 57 with tube 58, and as the valve 59 is moved to one position, Fig. 8, or another, Fig.7, the tube and hose connect either with the suction or exhaust 60 or with inlet 61. When the exhaust or tube 60 is in communication with tube 1, the air entering the mouth or free end of the latter will cause a sheet to adhere to or be fed by such tube 1.

When this feeder 1 has delivered a'sheet to rollers f and the communication between .feeder 1 and exhaust 60 is cut off and communication with inlet 61 opened, the feeder 1 releases the sheet, or, as it might opularly be expressed, the suction is interrupted. A sheetreleased by feeder 1 and taken by rollers f, as already noted, is fed out to apron' g. The valve 59 or its lever can be set or actuated by link 62, Fig. 2, oscillated by shaft or pulley 12, with which this link has a suitable eccentric or crank-pin connection.

As seen in Fig; 1, wires or fingers 63 can be adj ustably secured to a side piece a and made to hold the signatures 0 against the other side piece and forward toward feeder 1, these fingers 63 being set as required by larger or smaller sheets 0.
