PRINTING-PRESS.
Specification of Letters Patent.
Patented Mar. 5, 1912.
Application filed A ril 19, 1909. Serial No. 489,588. a
To all whom it may concern:
Be it known that I, WALTER H. SMITH, of Niles, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Printing-Presses; and
I do hereby declare the following to be a.
full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The primary object of this invention is to provide in a printing or numbering machine, or a combined printing and numberhaving means for throwing 011' the impression, improved means for automatically restoring the impression. By such improved means, regardless of the fact that the press is constantly in operation, there will be no cooperative relation between the cylinders of a printing press, or any imprint of the head or heads of a numberin machine, when the impression is thrown-o but the parts will be caused to automatically resume their normalpositions.
A further object is to provide in a printing or numbering machine, or a combined printing and numbering machine, having means for automatically throwing off the impression in the event of any interruption in the feed supply, improved means, for automatically restoring the impression. By such improved means there will be no cooperative relation between the cylinders of a printing press, or any imprint of the head or heads of a numbering machine, if there is any interruption in the feed supply, but the parts will be caused to automatically resume their normal positions and so remain when and as long as the feed supply continues unbroken.
The invention will be hereinafter fully set forth and particularly pointed out in the claims.
In the accompanying drawings, Figure 1 is a plan View. Fig. 2 is a side elevation.
Referring to the drawings, 1 designates a numbering cylinder; 2 a plate-carrying cylinder; 3 an impression cylinder and 1 the-trimming cylinder of a paper trimming machine in connection with which my present improvements may be employed, but its use is in no sense restricted thereto, nor is it confined to a combined printing and numbering machine.
5 and 6 designate upper and lower tapes for conveying the stock from the trimming cylinder to the impression cylinder, but any suitable means ma be employed for this purpose, and likewise the stock may be fed directly to the impression cylinder without being previously trimmed.
Extending transversely of the machine, between the flights of tapes 5, I have shown a reciprocating shaft 7 whereon is a tubular shaft or spindle 8 carrying at its inner end a disk 9 with which a feeler lever 10 carried by shaft 7 is designed tointerlock in.
the event of any interruption in the feed supply and through the turning of the tubular shaft 8 efi'ect the automatic throw oflf of the press. The means for effecting this purpose forms no part of my present invention, eing embraced by Letters .Patent issued June 15th, 1909, No. 925,047. Any suitable means may be employed for impart-ing to the feeler lever shaft 7 a reciprocating movement.
The impression cylinder 3 is shown as being shiftable, that is, it is mounted in eccentrio bearings 12, extensions of which are connected by adjustable rods 13 to arms 1 1 fast on a spring impelled shaft 15, which latter is shown as surrounded by a coiled spring 16, and as supported by the sides of the machine. The tendency of spring 16 is to turn shaft 15 in the direction of the arrow, Fig.
2, to eifect the throw ofl". Fast on shaft 15, at one end thereof, is an arm 17 which on its hub has a shoulder 18 with which engages the lower hooked end of a vertically disposed trip-lever 19. The upper end of lever 19 is designed to be engaged by a screw 20 carried by an arm 21 depending from a short shaft 22 having its bearing in the press frame,-said shaft also carrying an upwardly extending arm 23 with which is designed to engage a pin 24 of an arm 25 mounted on tubular shaft 8. When this shaft is caused to rotate with the constantly operated shaft 7, through the instrumentality of the feeler lever, arm 8 will act on arm 23, shaft 22, and arm 21, to turn lever 19 so as to release shaft 15 and permit ittto partly rotate under the action of spring 16 and thereby throw off the impression. In addition toautomatically throwing off the impression'this movement of shaft may also efiect a change in position of one or more devices which nor-' mally cofiperate to effect the change of the dies or wheels of numbering heads (not shown) carried by cylinder 1. The idea here present is embraced by Letters Patent 'of the United States'N'o. 764,289 issued to Charles G. Harris, July 5, 1904. In the present instance I have shown a trip roll 26 carried by an arm 27 mounted on a short shaft 28, which shaft isconnected by an arm 29 and'rod 30 to arm 17. When imits normal position, roll 26 will insurethe successive operations o'fthe actuating'shafts of several numberin heads, but when shaft 15 is released by trip-lever 19 roll 26 will be thrown out of its working position. Hence while the impression is ofithe dies of the numbering heads will not be affected by roll 26 although the presscylinders continue to rotate. I have shown two trip rolls 26 and 26, one, at each side of the machine, so that there may be employed two separate series of numbering heads, having independent actuating'shafts, after the manner set forth in my application for patent filed April26, 1909, Serial No. 492,223.
k The means for automatically restoring the-impression, and shifting the tri rolls when numbering heads are em loye may be varied, but I shall now descri e one form 35- which I have found .of advantage.
31 is a lever which is. fulcrumed on a stud 32 at one sideof the press. This lever at one end carries a roll .33 which isnormally held by a spring 34 against a cam 35, which cam is shown as mounted on the shaft ofthe impression cylinderand as revoluble therey with, but it may be otherwise. located and operated provided its action on the lever 31 will occur once in each revolution of the press cylinders. At its other end lever 31 carriedby a stud 36 which extends laterally beneath a shoulder 37 of lever'38 fast on shaft 15.
This lever has an arm 39 corresponding'to arm 17 \and connected in the manner .de-
scribedin connection with the latter to a This allowsof 'on and the numbering headtrip rolls are restored to their normal positions. If, however, no stock is inter osed at the proper time to prevent the reocking of the fee er .SlOIl of a'spring 41, and S1 en cam v lever and disk 9 theimpression will be again thrown off and the trip rolls shifted before theplatecylinder can act on the impression civllmder or any of the numbering. head S afts engage such trip rolls.
I have shown stud 36 as mounted on the f end of a. rod having a knurled head 4050 that by pulling-the latter, to overcome the teni htly turning such stud axially it will be field retracted by means of a lug 42. This is of advantage when it. is desired to work up the inking rolls, wear of the parts-being avoided by preventing the constant throwin on and off of the impression and the switching of the numbering head trip rolls.
The various parts are so arranged that- -at the moment the shouldered end oflever 38 is raised by the lever 31, the feeler lever 10 is starting on its forward travel. By the action of lever 31 on lever 38 the impression is thrown on and the trip rolls 26 and 26 positioned to'engage-the numbering head shafts. If no stock is present, the impression :is immediately thrown off, since the feeler lever will again lock with disk 9 and release the trip-lever 19' from shaft 15 which will turn under the action of its spring to throw off the impression and change the positions of trip rolls. 26 and 26. The upward movement of stud 36 of lever 31, to effectthe re-setting of shaft 15, occurs when all the numbering head actuating shafts have passed the rolls ,26 and 26 in one cycle of operation and when the printing cylinder has passed out of 006perative relation to the impression cylinder.
If the parts have been previously thrown off they will now be thrown on and so' remain as long as stock is in position to be engaged by thefeeler lever. If during the next cycle of operation no sheet should be in position to be engaged by the feeler lever v the trip mechanism will be actuated to re-' lease shaft 15,, to effect the throw off and shift the positions of the numbering head trip rolls 26 and 26.
. My present invention is of primary advantage in connection with printing presses having means for feeding stock from two different positioning points to the point of feeding to the press. It is possible for one of the two-o erators or'feeders to entirely discontinue coding and yet not interfere with ,the press handling the stock supplied by the other operator or feeder. In other words, even though stock may be absent for one cycle of operation and the throw olf efi'ected, the parts will be immediately restored to their proper positions in ample time for the next cycle of operation. The
use of the present improvements, however,
is in no wayrest-ricted and may be employed in connection with hand fed -presses. Heretofore it has been customary to provide-machines with foot pedals or hand levers to restore the parts to their normal positions by manual power. With my invention the operator is required to, give attention only to the feeding of the stock, the throw-off and throw-on being automatically effected.
