NUMBERING-HEAD.

Application filed August a, 1910. Serial No. 575,292.

To all whom it may concern} Be it known that I, WALTER Il. Saturn, a resident of Niles, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Numbering-Heads: and 1 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.

It is well known that in starting the operation of a numbering machine, or a press using numbering heads, it is necessary for the operator to thoroughly ink all the heads, that is, each and-every character of each die wheel of each numbering head for printin This is ordinarily accomplished by manually advancing each die-wheel one point and then running the ress with the ink rolls duly setfor severe revolutions. This inks all the numbers of due row. Then the diewheels are severally advanced,-one at a time, each one number, and then the new row is inked. This oieration of advancing by hand each num er of each die-wheel and inking eilch row is repeated as many times as there are characters around the diewheels.- In highclass Work it is necessary to ink the die-wheels from five to seven times in order to secure uniformity in print. This lnkmg operation consumes much time, 68138012111 on resses where there are a pinrality o hea s.

The primary object of my invention is a) rovide each numbering head with means or automatically turning all the dic whcels in unison so as to advance all of the die. Wheels conjoint-1y in each operation without changin the numbers in any row, thus enabling a l of the characters to be inked in a comparatively few operations. And a' further object is to provide simple and highly eflicient means for controlling such attach ment.

In the accompanying drawings, Figure .1 is a side elevation,.w1th arts in section, showing a numbermghea equipped with my. improvement. .F1g. 2 is a sim lar-view showin the parts in operative osition.

means normally inoperative so as to ermit the die-wheels to erform their usua funct1on,'the numbers lieing changed in each operation and the wheels successively rotated, but which when thrown into operation serves to etfect the simultaneous rotation of all the die-wheels automatically without changing their relative positions.

I will-describe my invention as applied to a standard numbering head, of a well known type, comprising a serieslof die-wheels carpawl carrier being actuated by ashaft Th1s construction 1s well known and hence further description thereof is unnecessaiy.

Patented Ma 1911.

These actuating Although I do not restrict myself to any special means for carrying out my invention, yet I have found that bestresults are obtainedby mountin on the pawl carrier :1 second. series.of paw s 10 prQ eetin from a common plate 12, which 13 ivotex on the carrier and on whose pivot 1s a sprin 13, the oilice of which is'to throw the paw s simultaneously Iinto en a meat with the ratchets of the severa ie wheelsfi Normally the p'awls 1.0 are held ino erative' so that they cannot engage the rate cts of the die-wheels in the reci rocation of the pawl carrier. The means or holding the pawls thus ino erative may be varied, and when the attac ment is to be applied to numbering heads already in use diflerent means may be used from that which is preferable in specially constructed numbering heads.

In Fi l to 3 I have shown a wheel'ls'i mounte on the same axis as the die-wheels, and parallel to the latter, having adjacent the peri he a series of cams 16, in number pre era 1 a out one-half the number of the teeth in t e ratchets 2. This cam wheel also carries, on the side opposite to the cams, ratchet teeth 17 with which an extra retainmg pawl will engage. When-th'e'wheel is Briefly stated, my invention comprises the outer one of the series of pawls (see Fig. 1) all of the latter will e held ino erative' and the die-wheels will work in t e usual manner. When, however, the' cam wheel is turned so as to free the pawl of the serieslO all of the latter will be swung inwardly under the action ofspring 13 and will simultaneously enga e the ratchets of all the die-wheels (see Fig. 2). When this occurs, at each operation of the shaft all of the die-wheels will be turned in unison without changing any die-wheel relatively to the others. Hence the numbers represented by the several rows will remain unaltered. After the inking operation is completed wheel 15 is given a partial turn so that one of its cams will engage one of the pawls of the series 10 and hold all of them inoperative.

For adaptin my improvement to numbering heads a ready in'use, it may be preferred to provide different means from that described for normally holding thesupple- "mental pawls out. of engagement with the die-wheels. For this purpose, various means may be employed, but I lave found that a button pivotally mounted on the pawl carrier answers every purpose. This button when placed in engagement with plate 12 of the supplemental pawls will rock the latter on their pivot to prevent them from engaging the ratchets, but when turned to free such plate the pawls Wlll, by their spring, be thrown into engagement with the ratchets. I have shown the pivoted post of,

this button as surrounded by a spring 21 to prevent accidental disengagement from the pawl plate. 1

p The advantages of my invention will be readily appreciated by those skilled in the art. It will be seen that by means thereof a great saving of time maybe effected in inkmg all the numerals or characters and without changing the relation between the diewheels so that in beginning a days operation all of the characters may be inked preparatoryv to resuming numbering operations without any appreciable loss of time.

I wish it to be understood that I do not 1 restrict myself to the exactmeans shown and described for carrying out mzsinvention, since changes may be made wit out departing from the spirit of the invention I claim as my invention 1.
