TYPE-HEAD FOR PRINTING AND'MARKING MACHINES.

Application filed February 2 1, 1911.

To all whom it may concern:

Beit known that I, ERASTUS VVooDwARD, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Type-Heads for Printing and Marking Machines, of which the following is a specification.

' This invention relates to improvements in typeheads for printing and marking machines and is especially adapted to the type of machine shown and described in my application Ser. No. 527,633, filed Nov. 12,

. controls the release and actuation of the disk without allowing the disk retaining pawl to drag over the type.

In the accompanying drawings is illustrated a construction embodying my inven t j disks are divided into groups in which the Figure 1 is a side elevation showing the.

' a screw E to the rock shaft G. E is the inking mechanism which is carried on the lower end of the lever D which is secured by a set screw D to the rock shaft D. Both the rock shafts G and I) are journaled in the frame C as shown and described in the application above refered to. The table or work support H carries the cushion H upon which the work is mounted and upon which the impression is made by the type. The usual type disks carrying on their outer periphery the type or marking characters are rotatably mounted on a central shaft J 4 which is journaled in the typehead J. On one end of the shaft J which projects beyond its bearing in the type head is secured by a pin J, a handle J for turning the shaft J and for frictionally turning those of the type disks which are released by suitable retaining pawls pivoted on the shaft J so that the required figures or characters carried on the periphery of the disks may be moved into alinement by the operation of said handle J In the marking of shoe linings the type disks 1, 2 and 3 are for marking the size of the shoe, the disks 4 and 5 the width, the disks 6, 7, 8, 9, 10 and 11 the case number, while disks 12 and 13 are for mate marking. The latter two disks 12 and 13 are operated by means of a handle J secured to the outer end of a shaft 3 1 by a set screw J These mate marking disks are so arranged as to be operated by a partial turn of the handle J 7 to adjust the numerals carried by said disk to print duplicate numbers in numerical order from 1 to 99. In each of the other groups the disks required to be changed or adjusted most frequently are operated by levers 14, 15, 16, 17, 18 and 19. Each disk to be operated in this manner carries a single operating lever, the arrangement of which is particularly illustrated in Figs. 6, 7, 8, 9 and 10. In Fig. 6 the type disk 2 is shown rotatably mounted on the shaft J This disk is normally held in position by a retaining member 20 which is pivoted on the shaft J and actuated by means of a spring plunger 22 mounted in the type head J and actuated by a spring 23. The retainingpor tion 24 is adapted to'engage between the type carried on the disk and prevents the disk from turning except when said retaining member is released.

25 is a supporting member which is mounted at the side of the disk to be operated and over one of the washers 26, said member being supported on the opposite side'by the adjacent disk. Pivoted to the supporting member 25 at 27 is the operating lever 15. A roll 28 is pivoted on the operating lever 15 in a position to engage and roll upon the inner face of the retaining jmember 20, so that when the lever 15 is 15 the retaining member 20 (see Fig. 7), withdrawing portion 24 from the recess between moved partially forward the roll 28 lifts the type and holding the sameout of contact with any portion of the type disk. At

the same time the forward movement of over thecharacters or type until the roll 28 has passed from under the end of the retaining member 20 when the spring plunger 22 causes the lower portion 24 to drop into the following recess, thereby locking the disk and lever 15 against further movement. A return movement of the operating lever 15 disengages the pawl 29, see Fig. 8, while the roll'28 engages the under side of retaining member 20 until it reaches its normal position asshown'in Fig. 6, allow V ing'the lower portion 24 to engage one of the recesses and holding the disk secure against further movement. The operating lever 15 is identical inconstruction'and operation with the remaining levers 16, 17, 18 and 19.

The handle J (see Figs. 2 and 5) is a modification of the operating lever heretofore described, the difference being that two disks, namely 12 and 13 are operated a by the one handle or lever, to adjust the characters in numerical order." The disk 12 carries the numerals representing the tens column and is normally retained in position by the retaining member or pawl 30, which pawl issecured to a shaft J and is held in position by the usual spring plunger. This. shaft Jf is rotatably mounted in a bear:

ing in one. side of the type head J and is hollowed forming a bearing for the reduced on the shaft J The disk 13 carries the nuand 13 are mounted on a separate shaft 34,

which is journaled in a bearing 35 on type head This shaft 34 is hollowed and receives the reduced end of the shaft J 4 forming a bearing for that end ofsaid shaft J,

allowing the shaft J to be turned independent of the shaft 34. Secured to the shaft 34 is a ratchet wheel 36 carrying a number of teeth corresponding to the number of numerals on the type disk 13, said teeth adapted to cooperate with a pawl 37 secured to the shaft 32. On the inner face of the ratchet wheel 36 is carried a member 38 which engages at every complete revolution of the ratchet wheel 36 with a pawl 39 secured to one end of the shaft J Theoperation of the two disks 12 and 13 for mate marking the shoe linings is as follows: Commencing with numeral 1 and duplicating the same, the operator then turns the hand wheel J 7 a partial turn causing the pawl 37 to rise on one of the teeth of the ratchet wheel 36 which movement of said pawl 37 acts through shaft 32 to lift the retaining pawl 31, while a further movement of the handle J acting through the usual friction washer actuatesthe'disk 13 to a position formaking an impressionof the numeral 2 on the shoe lining. WVhen the other shoe lining or mate is marked with [the numeral 2 the hand wheel J is again operated to the numeral 3, etc, until after i the numeral 9 has been printed, when a further turn of the hand wheel J 7 causes the member 38 to lift the pawl 39 and through shaft J torelease the pawl '30, permitting the tens disk 12 to register the numeral 1,

while at the same time'the units disk 13 registers the 0, each succeeding movement of the hand wheel J 7 moves the numerals forward by units, the disk 12 being adjusted 1 numeral forward to every 9 numerals of the units disk. When itis desired to reset the mate marking disks 12 and 13 to commence renumbering with the numeral 1 the pawls 30 and 31 are released by hand and the hand wheel J 7 moved in the opposite direction, both disks 12 and 13 being moved by the usual friction washers until the pin 40 on the disk 13 is engaged by'the pawl 41 pivoted on shaft '32 and the pin 42 on the disk 12 is engaged by the'pawl 43, on shaft 32. The disks 12 and .13 are now in aline ment to commence 'renumbering with the numeral 1, when the pawls 30 and 31 may be released locking both disks in position. The handle-J is. now' turned until the member 38 engages the spring pawl 49 secured to one'side of thetype head J. This pawl prevents anyfurther rotation: of the'h'andleJ,

printing tension.

and serves to locate the relative positions of the ratchet wheel 36 and the tens disk 12, so that said disk will be actuated one numeral forward to every tenth numeral on the units disk.

50 is a gage which is secured to the side of the type head J (see Figs. 2 and 3), and which straddles the shaft J 4 and is secured at its upper end by a screw 51 to the type head J. The gage 50 is adjustable when the screw 51 is released, by means of an adjusting screw 52, which is threaded into the upper portion of the type head J, movement of the gage 50 being allowed by means of the slot 53 through which the screw 51 is mounted. A. spring 54 is secured at one end to a pin 55 located inone side of the type head J and at its opposite end to a pin 56 secured to the gage 50. This spring normally holds the upper portion of the gage 50 in contact with the shoulder of the adjusting screw 52, so that when the screw 52 is turned in either direction the gage 50 will move up or down and when finally adjusted the said gage 50 is secured in position by tightening the screw 51. 57 is a striking piece carried on the table or work support H and adapted to be engaged by the gage 50 when the impression is made to move the table H against its The adjustment of this gage regulates the depth of the impression or in other words the distance into which the type is forced into the work when the impression is being made, so that by this means of adjustment it is possible to secure the clearest impression of the type.

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:

1. In a typehead, an adjustable type disk, a pivoted member normally locking said disk in adjusted position, an oscillating member supported at the side of said disk and carrying pivoted thereto an actuating pawl, said pawl adapted to operate the pivoted member during its forward movement to release and actuate the type disk to change its printing position and on its return movement to release said locking member to lock said disk in adjusted position.

2. In an apparatus of the character de scribed, the combination with a type head and a yielding work support of a plate mounted at the side of said typehead and adapted to engage said work support to regulate the depth of the impression on the work, and a screw for adjusting and maintaining said plate in position on said typehead.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this 13th day of February A. D. 1911.

ERASTUS VVOODWARD.
