PRINTING-PRESS COUNTING AND SIGNALING MECHANISM.

Application filed February 16, 1920. Serial No. 358,971.

To all whom it may concern.

Be it known that I, EDWARD CHESHIRE, a citizen of the United States, residing at Milwaukee, in'the county of Milwaukee and 6 State of Wisconsin, have invented certain new and useful Improvements in Printing- Press Counting and Signaling Mechanisms, of which the following is a specification.

This invention relates to counting and signaling mechanism for printing presses. In my application Serial No. 329,976, filed October 11, 1919, I have disclosed and claimed certain improvements in printing presses. In this present application, I am describing and claiming more particularly the counting and signaling mechanism to be used in connection with such printing presses.

One object of this invention is to count 2 accurately and automatically the number of sheets of material passed through the press and to give automatically a signal when for any reason a sheet of material has not been fed toward the impression means.

Another object is to provide simple and novel counting and signaling mechanism for printing presses adapted to meet the various requirements for successful commercial operation.

These and other objects are accomplished by means'of the arrangement disclosed on the accompanying sheets of drawings, in which- 7 Figure l is a front elevation of a printing press embodying my invention, parts thereof being omitted for the sake of clearness;

Figure 2 is a side elevation of the same printing press;

Figure 3 is a sectional view of the same press taken through the printing cylinder and a stationary part 0 the press, and showing more in particular, on a larger scale, the operating mechanism for the counting mechanism and slgnaling mechanism; and

Figure 4 is a detail sectional view taken in the plane of line 4-4 of Figure 3.

The variousvnovel features of my invention will be a parent from the following description and drawings, and will be articularly pointed out inthe appended claims.

The particular printing press in connection with which I am disclosing my present invention is described in detail in my above mentioned application. Accordingly, only such parts wlnch are necessary to an under standing of my present invention will be described herein,

The frame 10 of the printing press carries a bed plate, it being understood that as the impression cylinder 11 moves rectilinearly in one direction, the rack bar 12 with the cylinder bed moves rectilinearly in the opposite direction. During the upward rectilinear movement of the cylinder 11, it also rotates for giving the sheet of material carried thereby an impression, preparatory to removal of such sheet of material from the cylinder at the upper limit of movement of the latter. Durlng the downward movement of the cylinder 11, it does not rotate. Whether or not the cylinder 11 rotates depends upon whether or not it is locked to the actuating gear 13 which meshes with the rack 12.

Referring particularly to Figure 3, it will be noted that one end wall of the cylinder has secured thereto a fulcrum 14, to which is pivotally connected a lever 15, to one end of which is pivotally connected a movable lock member 16, which may be reciprocated through an opening 17 in one end of the cylinder, said movable lock member being movable into and out of engagement with a co-operating lock member 18 secured to the web 19 of the cylinder driving gear 13.

As fully described in said above mentioned application, the movable lock member 16 is operatively connected to a bell crank lever 20, which carries at the end of one of its arms a dog 21 yieldably held in adjusted position with respect to said bell crank lever. The upper end of the dog 21 is engaged and actuated by a block 22 at the upper end of a bar 23 for unlocking the cylinder, or, in other words, moving the lock member 16 out of engagement with the lock member 18, this unlocking action taking place at the upper limit of movement of the cylinder preparatory to a downward movement of the cylinder during which time it does not rotate. At the lower limit of movement, the c linder is locked, or, in other words, the dbg 21 is given a quick and short upward movement tozmove the looking member '16 into engagement with the locking member 18, preparatory to an up en aged by the b ock 22 for unlocking the cy inder and for moving the lower end of the dog 21 to the left for forcing an air controlled plunger 24 and its stem 25 inwardly with respect to the cylinder 26 thereof, it being understood that this action takes place at the upper limit of movement of. the 1mpresion cylinder.

As described in said above mentioned application, the cylinder frame carries a transfer table 27, which receives sheets of material from the stock pile when the transfer table is in its upper position with the impression cylinder. This transfer table wilt perforations extending therethrough, which are connected to a source of vacuum. soon as a sheet of material is placed upon the transfer table 27, the perforations are covered, causing the plunger 24 and its stem v25 to move outwardly or to the right, as

shown in Figure 3, causing the lower end of the dog 21 to move to the right. On the other hand, if for any reason a sheet of ma: terial is not fed to the transfer table in its upper position, the perforations in the transfer table will not be covered, and accordingly the plunger 24 and its stem 25 will not be moved to the ri ht, as shown in Figure 3, and the lower en of the dog will not be moved to the right. In other words, the lower end of the dog has two distinct positions: In one position, when it is swung to the right, a sheet of material has been fed to the transfer table and covers the perforations thereof. In the other position, when it is swung to the left and remains there even after the transfer table and cylinder start in their downward movement, no sheet of.

material has been fed to the transfer table and the perforations thereof are not covered. When a sheet of material is fed to the transfer table, said sheet of material moves downwardly with the transfer table and c linder, the material being properly aligne and fed to the cylinder at the lower limit of movement of the latter.

The sheet of material thus fed to the impression cylinder is registered on the countmg mechanism, the counting mechanism taking the form of any desirable register or meter 28, which may be operated through a rod 29, which near its lower end is provided with a collar 30, the lower end of the rod beingsupported and guided by a bracket 31 secured to an arm 32 of the printing press frame, it being remembered that when a sheet of material is on the transfer table, the lower end of the dog 21 is in its right hand position. It is apparent that when the cylinder carrying the dog 21 is moved downwardly and approaches its lower limit of movement, the lower end of the dog engages the collar 30, thereby giving the rod 29 a slight downward movement, causing an operation of the register or meter 28. It is equally apparent that if no sheet of material is fed'to the transfer table, the lower end of the do 21 will occupy its left hand position, an in its downward movement with the cylinder near the lower limit of movement of the latter will engage a collar 33 carried near the lower end of a rod 34, giving the latter ashort downward movement for sounding any suitable signal, such as a bell 35, wh1ch will indicate the operating condition of the press; or, in other words, that material is not. being fed to the transfer table and impression cylinder.

The rod 34 also is guided and supported by the bracket 31. Indotted lines in Figure 3, the bell rod 34 is shown in its signaling position. The collars 30 and 33 are adjust able upon their rods to meet varying conditions.

I have thus shown and described in connection with my printing press, counting means, signal means, and pneumatically and automatically controlled cylinder lock mechanism for operating one or the other of said counting or signal means in accordance with operating conditions of the ress, the counting mechanism being operated for registering each sheet of material passin passing through the press, and the signa mechanism for calling the operators attention to the fact that material is not bein fed to the transfer table or impression cy inder. v

It will be understood that I do not limit my invention to the details herein shown and described, for it is apparent that in the broadest aspect of the invention, the counting and'signal means may be operated by other suitable mechanism of the printing press.

I claim:

1. In a printing press, the combination of counti means, signal means, and automatica y operated means for selectively operating said counting and signal means.

2. In a printing press, the combination of counting means, signal means, and cylinder lock mechanism for operating said counting and signal means.

3. In a printingpress, the combination of.

counting means, signal means, and a movably mounted printing member for operating said counting means and signal means in accordance with operating conditions of the press.

4. In a printing press, the combination of countin means, signal means, a reciprocatory cylinder, and means carried there y for operating either the counting means or sigother said member in one ditions of the ress.

'5. In a printmg press, the combination of counting means, s1 al means, a transfer table, and means w ereby either the count- I mg means or signal'means will be operated,

depending upon whether or not a sheet of material is placed upon said transfer table.

6. In a printing press, the combination of counting means, s1 a1 means, a stock receiving member, an means for selectively operating said counting means or signal means, dependin upon whether or not stock is placed on sai stock receiving member.

In a printing press, the combination of counting means, signal means, a vertically movable cylinder, a member carried thereby havin two positions with respect thereto, whereby either the counting means or signal means will be o rated in accordance with operating conditions of the press.

,8. In a printing press, the combination of counting means, slgnal means, a printing cylinder, lock means therefor, including a member which occupies one of two positions, said member in one position being arranged to operate the counting means and in the osition to operate the signal means.

9. a printing press, the combination of counting means, signal means, a printing cylinder, lock means therefor, including a member which occupies one of two positions, position being arranged to operate the counting means'and in the other position to operate the signal means, 7

and means for controlling the position of said member.

10. 'In a printing press, the combination of counting means, signal means, a printing cylinder,'lock means therefor, including a member which occupies one of two positions, said member in one position being arranged to operate the counting means and in the other position to operate the signal means, and means for automatically controllin the position of said member as a result of diflerent operative movements of the press mechanism.

11. In a printin press, the combination of counting'means iaving an operating rod, signal means having an operating rod, 2. movably mounted cylinder, and a member carried thereby for actuating one or the other of said rods for operating the counting means or signal means, depending u on whether or not a sheet of material is being fed to the press.

12. In a printing press, the combination of counting means having an operating member, signal means having an operating member, a reciprocatory im ression cylinder, and a member carrie thereb for actuating the operating member 0 said counting means or signal means, dependin upon w ether or not material is fed towar said impression cylinder.

Signed at Milwaukee, Wisconsin, this 27th day ofJanuary, 1920.
