PRINTING AND MAR-KING MACHINE.

Application filed March 14 1910.

T 0 all whom may concern:

Be it known that T, Erasmus lVooowann, of Senior *ille, in the county of Middlesex and State f fassachusetts, have invented certain new and useful Improvements in Printing and Marking ll lachines, of which the following is a specification.

My invention relates to improvements in printing and marking machines and relates especially {0 the automatic adjustment of the type head disks for the purpose of match marking shoe uppers or similar articles which are marked by pairs. Shoes are manufactured in lots or cases and each shoe is marked its size, its width and its lot number, and in the best grade of shoes they are match marked, and as far as I know these disks or types have to be changed by hand to meet the requirements. The lot number has to be changed once for each lot and the sizes and widths have to be changed five or siX times during the marking of each lot, and in match marking they have to be changed every pair, which makes it a slow and care-taking operation, and subject to frequent mistakes.

The object of this invention is to enable the match marking of each entire lot to be done automatically without the manual adjustment by the operator. After each entire lot has been marked the automatic marking mechanism or disks are reset to their initial numbering position by the turning of a disk by the operator.

This device is especially adapted to be operated in conjunction with printing and marking machines of the type shown and described in my application Ser. No. 527.633, filed November 12, 1909.

Figure 1 is a. side elevation of the auto matic match marking device with its actu ating mechanism operating in conjunction with the marking machine shown and described in my application Ser. No. 527,633, the position of the mechanism being normal. Figs. 2, 3, 4 and 5 are similar views showing the consecutive positions and operations of the parts between the impressions of the type head. Fig. 6 is a front elevation of Fig. 5 with the inking device removed. Fig. 7 is a front elevation of a portion of the type head which is automatically operated for match marking. Fig. 8 is a sectional view of the type head on line 88 looking in the direction indicated by the arrow. Fig. 9

is a longitudinal section on line 9 Fig. :2, showing a part of the disk carrying shaft and pawl supporting shaft. Fig. 10 is side elevation of the type head with the ratchet wheels and pawls removed and showing the stop for locating the unit disk and the pawl for locating the unit ratchet wheel.

Like letters of reference refer to like parts throughout the several views.

C represents the supporting frame of the machine described in my application Ser. No. 527,633, and carries the rock-shaft D mounted in the bearing C in the upper part thereof, said shaft having secured to its outer end the yoke arm D by set screw D This arm D carries mounted on its outer end the inking mechanism E.

The rockshaft G is mounted in the bearing C in the lower part of frame C and carries the lever or type arm G secured thereto by the set screw G The type head J is secured by the clamp screw J 2 to the outer end of the lever G The rock shafts D and G are thrown into coiiperation with and driven by a suitable clutch at each operation as described in the above named application.

H represents the work supporting table upon which the articles are placed to receive the impression of the type head J.

The type head J (see Fig. 6) comprise the usual series of ring type disks J rotatably mounted on a central shaft J t which is journaled in the typehead J. A knob J 5 is secured to the outer projecting end of shaft J and is for the purpose of manually adjusting and frictionally turning those of said type disks which are released by suitable pawls J pivoted on the shaft J so that the required figures or characters located on the periphery of the disks J may be moved into alinement for making an impression on the shoe linings to mark the size, width and lot number as heretofore stated. The automatically operated type disks T and U for match marking the shoe linings (see Figs. 7, 8 and 9) are loosely mounted over the enlarged portion of shaft V (Fig. 9) which is rotatably mounted in the bearing V of the type head J.

One end of the shaft J t is supported by and rotatably mounted within the shaft V. The washer V is located between and spaces the two disks T and U, and T and V are spring washers bearing respectively against shaft U which shaft is loosely mounted in a bearing in type head J. This pawl U is adapted to normally hold unit disk U in printing alinement.

T is a pawl secured to the inner end of shaft T which is loosely mounted in a bearing in typehead J. The pawl T normally holds the disk T in printing alinement.

V is a ratchet wheel pinned to the outer projecting end of shaft V and V is a knurled hand wheel mounted over the hub of said ratchet wheel V and pinned thereto. V is a similar ratchet wheel of slightly larger diameter and loosely mounted on said shaft V. Each of these ratchet wheels is provided with a series of equiangularly spaced teeth which are adapted to cooperate with the pawls P F and P in a manner hereinafter described.

U is a cam lever pinned to the outer end of the shaft U and is adapted to be consecutively operated by the rear cam face of each tooth located on the periphery of the ratchet wheel V T is a cam lever pinned to the outer end of the shaft T and adapted to be operated by a cam tooth T located on the inner face of the ratchet wheel V (see Fig. 1). The pawl U is held in locating contact with the unit disk 'U by a spring plunger U mounted in the type head J. The pawl T is held in locating contact with the tenths column disk T by a spring plunger T also mounted in the said type head J. The cam lever U is consecutively operated by one of the teeth on the ratchet wheel V after the match marking of each numeral on the disk U, the movement of this lever acting to lift the pawl U to permit the frictional turning and readjustment of the unit disk to the following numeral while the cam lever T is operated every tenths numeral to release the pawl T to permit the frictional adjustment of the disk T.

Loosely mounted over the shaft J is a gravity pawl T adapted to engage a pin T (see Figs. 8 and 9) when the pawl T is released by the hand and the knurled handle is turned backward and has moved the disk T to its initial numbering position.

U is a gravity pawl loosely mounted over the shaft U and is similarly adapted to en gage a pin U (see Figs. 9 and 10) on the side of the disk U to locate said disk in its initial numbering position when the pawl U is released by hand and the knurled handle V is operated backward to frictionally turn said disk to its initialposition.

X is a spring pawl secured to the lower part of the type head J and is adapted to engage the flat side of the cam T to adjust the ratchet wheel V in relative initial position with the unit and tens disk.

The pawl P is pivoted at P to the outer end of the arm 1, said arm being loosely mounted at its opposite end over the reduced end of the bearing and l eld thereon by a collar P secured to the shaft G. The pawls P and P are integral and are also pivoted at P to the outer end of the arm P.

P is a spring pinned at one end to the projecting arm P of the pawl P said spring being pinned at its opposite end'to the arm P. This spring normally holds the pawl P against cam face stop P which stop is pivoted at P to the outer end of the arm P and has a pin P by which said stop may be turned to throw the pawl P against the tension of spring P out of op erating position. P is a similar spring secured at one end to a projection P on the lower side of extension P and secured at its opposite end to the arm P connected with the pawls P and P This spring F normally iolds the arm P against the stop P thereby holdingthe p wls P and P in suitable operating position.

Mounted on the upper side of the arm P is a cam roll P which operates within the cam slot P and the lower end of the lever P. This lever is carried by and secured to the shaft D by a set screw P The operation of the device is as follows: When the operator has received a lot of shoe linings which are secured together in pairs or matched, a bunch of the same is placed on the work supporting table H the type head J being initially in the position shown in Fig. 1 with the unit and tenths disk set to its initial position. The operator now presses the foot pedal which throws into action with the driving power the clutch which has been fully described in my application hereinbefore referred to, which action of the clutch operates to move the rock shaft D, bringing the inking roll Ff into contact with the type (see Fig. 2) causing said roll to roll across the face of said type. In the meantime the cam lever P is operated to actuate the cam roll P and raise the arm P and pawls P P and P out of contact with the tooth of the ratchet wheels V and V During the passage of the roll 1 across the face of the type the rock shaft G operates the arm G to raise the type head J and the type located thereon in conjunction with the inking roll until the said roll has moved across the face of the type. The arm D and the inking mechanism E now temporarily suspends movement while a further movement of the arm G and type head J withdraws the type (see Fig. 3) from further contact with the ink roll E. This cooperative movement of the type with the ink roll E has caused said roll to ink the type and at the same time to automatically shift said roll to expose a fresh surface of the same for inking the type for the following impression. The arm D now acts to withdraw the inking mechanism E to the position shown in Fig. l while the arm G simultaneously acts to depress the type head J until the type is in contact with and stamps the impression or numeral one upon the upper lining of the bunch supported on the table H A continued movement of the arm G lifts the type head J and the type thereon out of contact with the work into the position shown in Fig. The operator now removes the lining which has been marked one, leaving the matched lining which is the next on the bunch, in position to receive a similar impression of the number one.

hen the type head J has reached the po sition as shown in Fig. 1, one of the teeth of the ratchet wheel V, which is indicated by the broken line Fig. at leading from said pawl P to the ratchet wheel V has been engaged and actuated by the pawl P during the upward movement of said type head and moves along to match the forward tooth of V leaving the operating teeth of both ratchet wheels V and V matched. In the meantime no movement of the rachet wheel V has been made because the pawl P would engage the outer face of one of the teeth of the ratchet wheel V as indicated by the broken line Fig. 4, causing the said pawl P and the pawl P to be thrown backward against the tension of spring P, the pawl l? holding the pawl P back from contact with the tooth of sprocket wheel V This operation has caused the ratchet wheel V to merely turn to match the operating teeth as shown in Fig. 5 without shifting either of the type disks or changing the numeral which makes the matched impression. The type disks are not shifted during this operation because they are locked by the pawls T and U until the operating teeth are matched so that on the next movement of the arm G the pawls P and P engage the teeth and move the disks V and V lifting the retaining pawl U and through shaft U lifting the retaining pawl U permitting the unit disk U to be moved one numeral forward. The type is again inked in the manner heretofore described and the type head J will descend and make a repetition of the impression of the numeral one on the lining to be match marked. As soon as the type head J moves from the printing position shown in Fig. at to the position shown in Fig. 5 the operator removes the lining from the top of the bunch exposing for marking the next pair of linings to be numbered two.

When the type head J has lifted to the position to engage the pawls P and P the teeth of the ratchet wheels V and V being matched as shown in Fig. 5 the said pawls P and P will drop into cooperation with said teeth, the pawl P acting first to engage the tooth of ratchet wheel V on account of its greater diameter than the ratchet wheel V causing the cam lever U to be lifted by one of the cam faces of the sprocket wheel V and throwing the pawl U out of engagement with the unit type disk U. This releases the type disk and causes the same to be in a position to be frictionally turned one step forward to the numeral two and immediately the pawl P engages with the operating tooth of the ratchet wheels, being moved one step forward. This movement of the ratchet wheel V acts to frictionally move the unit disk to place the numeral two of the same in printing position. In the meantime during this upward movement of the type head J the pawl P has engaged the outer face of one of the teeth of the sprocket wheel V, the said pawl being thrown against the tension of the spring P into an inoperative position. The type is now inked and the type head J descends and imprints the numeral two upon the upper lining of the bunch, which lining is then re moved by the operator and a repetition of the operation as described will cause the next lining to be match marked number two. It is obvious that the action of the pawl P and the pawls P and P are alternate; that is, when the pawls P and P act to move the unit type disk U to a consecutive number the pawl P is inoperative and when the pawl P acts to move the operating tooth of the ratchet wheel V to match the operating tooth of the ratchet wheel V the pawls P and P are rendered inoperative; in other words, the pawls P and P automatically act to move the unit disk to a consecutive or following number while the pawl P merely sets the ratchet wheel V without shifting the numeral of the unit wheel U which permits the match marking or duplicate impression of the unit numeral.

During the match marking of the linings from one to nine the tenths column disk T has exposed a blank, in other words, has been inoperative, but when the numeral nine on the units disk U has match marked, the cam T* on the ratchet V has reached a position whereby it engages the cam lever T so that on the next upward movement of the type head J the ratchet wheel V is actuated together with ratchet wheel V by means of pawls 1 and P, the cam T raising the cam lever T and releasing the pawl T while the ratchet wheel V acts to frictionally turn both type disks T and U placing the numeral one in printing position on the type disk two and the numeral Zero on the disk U in printing position, whereby on the next impression of the type head the numeral ten is stamped on the linings. In the meantime the pawls U and T have been released, locking the type disks T and U in alinement. When the operator has consecu tively match marked the number of pairs of linings in the lot and'desires to commence the automatic match marking of a new lot the pawls T and U are held back by the operator while the knurled hand wheel V is turned in a reverse direction from that indicated by the arrow in Fig. 1 until the locating pin U on the type disk U has engaged the gravity pawl U (see Fig. 10) and the locating pin 1" on the type disk T has engaged the gravity pawl 'I Fig. 8 stopping further movement of the type disks T andU and locating the same in their initial position for marking the numeral one. In the meantime the cam T on the ratchet wheel V has engaged the spring pawl X locating the said ratchet wheel in its initial position. The operator now, releases the pawls T and U locking the type disks in initial position. The machine is now in position to commence the match marking of the new lot of linings.

Having thus described my invention and set forth a construction embodying the same what I claim as new and desire to secure by Letters Patent of the United States is:
