Application'filed September 25, 1924. Serial No. 739,937.

To, all whom it may canoe 1%: I Be it known that I, GUY L. KEENE, a

' zen of the United States,residing at Brookton, in the county of Plymouth and Commonwealth of Massachusetts have invented certain Improvements in Marking Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. T

This invention relates to marking machines and more particularly to the type-carrying heads thereof.

Marking machines for numberingand labeling shoe parts-,clothing andthe like are commonly arranged to apply a row of characters, which must be changed frequently, combined with other printed. matter such as changed less frequently. An arrangement of this character is illustrated in United States Letters Patent No. 1,170, 90, granted February 1, 1916, on the application of Edward B. Parkhurst, in which the marking head is provided with a plurality of rotatable type-wheels bearing numbers or letters adapted to be adjusted at will together with a type-plate, sometimes called a' trade-. plate, upon which-other printed matter has been engraved. As shown in said patent, the type-plate is detachable and retained in position uponthe marking head by jaws, one of which is pivoted andjresilientlyheld in clamping position so that it maybe released and the plate removed at will. Itis desirable that the characters 'upon the type plate shall be as close as possible to the characters on'the type-wheels'when the impression is made so that the whole imprint may occupy as little'space as possible and,- in the case of-shoes, may all be mar the top of the lining of the shoe. On theother hand, .rotation of thetype-wheels without interference with the edges of the type-plate upon which the fixed rows of, characters appear requires that the slot through wh-ichthe characters on the type-wheels pass shall be of substantial size; In order to attain as.

compact an arrangement as is desirable, the name-plates are commonly arranged with only a narrow slot, and the rows ofcharacters are disposed along the sides of this slot. The width of this slot may be only so much as is necessary to admit a single'row of type cition the type-wheels. In view of this arrangement, the operator, when-shevwishes to turn the type-wheels, must open the jaws and partially or wholly remove the nameplate. In the arrangement disclosed in the Parkhurst patent,-the openingof the jaws allows the plateto'drop out. The common practice is for the operator to catch the plate in her hand and thenafter setting the typewheels, return theplate to position and lock it in position within the jaws. This soils the operato-rs hand andis, of course, inconvenient and time-consuming. 1 v

Accordingly an objectof the invention is to provide a retainer for "the type-plate of a marking head, which will allow the partial separation of the type-plate from the typewheels when the plate is released without allowing itwholly to drop out of the jaws. names or trade-marks, which need i to be r In the illustrated machine, in accordance with features-of the invention, a projecting stud is inserted-inone side of the frame of the marking head and a retaining bail pivotally connected to the ends of the typeplate is passed around'the ends and side of the marking head and disposed abovethe projecting stud.

The dimensions of the bail and adjacent parts are 'suchthat when the For a. more icomplete' understanding of the invention, reference maybe-had to the following specification taken in connection with the accompanying drawing in which: Fig. 1 is a front elevation head embodyingth invention;

Fig. 2 is a side elevation partly in section showing the type-plate held in position by the.jaws;'and" [Fig 3 is a'similar elevation showing the type-plate released from the movable jaw and supported by the bail.

Marking machines of the type under conof a marking loo sideration are commonly provided with a worlr support and a reciprocating or oscillating mechanism adapted to carry the typecarrying marking head into and out of contact vith the work. For the purpose of illustration, there has been shown a type-head having a frame 10 within which are sup-- ported type- wheels 12, 14, 16, etc, capable of being turned on or with a shaft 18 trictionally engaging said wheels. The shaft 18 isprovided with an operating handle 20. Latches. 22 having finger pieces 24 are. provided for each individual type-wheel, and the latches normally hold the type-wheels in fined position but may be released by depreisin-g thefirrger pieces 24 to allow the setting ot one or more type-Wheels by rotation o l? the operating handle 20.

In order that the machine may be enabled to print more than the characters provided upon the typewheels, the frame 1t) of the marking head is provided with jaws 26 and 28 which are slotted to: engage the edges of a type-plate 30. The slotted jaw 28- is displaceably supported upon, a hell crank lever 32 provided with a finger piece 34: and normall yl-ield in closed position; by means of a spring-operated plunger 36. The. type plate may take any one oii a large variety of i orins and is herein illustrated as provided with a detach-ablev electrotype 38 anda row of interchangeable type-members 40 which are placed adjacent to the edges Oili a slot in: said plate which receives that row 42 of type on the type-wheels which is inoperative position for marking the work. The arrangement oit' the type-plate; is such that the marking surfacesot the removabletypemembers 40, the row of type 42, and theelectrotype 38 are flush. with one another.

To allow the partial separation otthe type-pl-ate troni the type-head without fully releasing it when the movable jaw 28 is opened, a plate-retainer having the form of a bail d3, preferably constructed ofspring wire, is provided. The intu-rned ends of the bail 43 are entered in sockets a l at the ends of the typeplate adjacent to the edge which is; received within the groove of the fixed jaw' 26, and then the loopof the bail is passcdaroundthe ends and across the side of the frame of the marking head above a stud 4,6. The retaining bail is so adjusted and designed that when the. jaw 28 is opened, the plate will bepartia'l ly released and will drop to the position illustrated in Fig; 3 in which it is retained, supported by the bail and by frictional engagement of the upper surface. of the plate withthe lower surface ofthe frame of the marking head and by engagement of the lateral edge of the platewith the lateral face of the fixed jaw 26. By relieving the upper edge d7 of the type-plate, as by cham'teri ng, the operator is enabled completely to remove the type-plate from the marking head by turning it around the points of attachment. of the ends. of the bail and the corner 48 of the 26 until it has been rotated through substantially 180 degrees, whereupon it may be moved aterally to remove it from the marking head. It will be noted also that the lower corner 50 of the grooved movable aw 28 is slightly beveled so that the type-plate may be pressed into the groove of the movable jaw 28 without necessarily depressing the finger piece 24 thereof.

In using the machine, whenever the operator'wishesto change the position of the. typewheeis, she will first depress the finger piece 554i and allow the type-plate to drop into the position shown in Fig. 3 where it will be held by the action oi the retaining bail 43.

She will then depress the particular finger piece 24: corresponding to the type-wheel which it is desired to rotate and by turning the operating handle 20 will bring into position in the row or" types 42 the particular character which it is desired to use. Preferably she will then replace the typeplate within the aw 28, but if this action on? replacement is torgotten, the plate will be prrhed into position and the jaw 28 will snap over the edge of the plate when the ag head is depressed. ha ving thus described the invention, What I claim as new and desire tosecure by Letters Patent of the United States is:

In a type-head, a supporting surface, a fixed jaw adjacent to one side of saidsurface, a type-plate, displaceable'means acting in conjunction with said fixed jaw to retain the type-plate normally against said supporting surface and allowing it to drop away from said surface when displaced, and other means acting in conjunction'with said fixed jaw to retain said plate'in a position slightly separated from the supporting surface. whenreleased from the displaceable means.

5. In a type-head,- a type-plate resting against a supporting surface of said head, a frame provided with a lateral recess adapted to receive and support the lateral edge of the typeplate, a projection on the frame, and a retaining bail passing over said fixed projection pivotally secured to the ends of the type-plate, said bail being constructed and arranged to support the type-plate inengagement with said recess, and in a position slightly separated from the platesupporting surface upon the type-head.

6. In a type-head, a frame,"one or more type-wheels rotatably mounted within said frame, jaws upon said frame one of which is movable, a type-plate having characters flush with the character upon the type-wheel and held in position by said jaws,'and a re taining bail engaging the-edges of the'type plate away from the movable jaw and passing over a projecting part of the type-head, arranged to allow the type-plate to be separated sufficiently from the type-head to al- 7 low rotational adjustment of the type-wheel 7 without wholly removing the type-plate from the type-head. V

7. In a type-head, a plurality of typewheels rotatably mounted foradjustment within said head to bring a row of characters in position adjacent to the end of the head for marking the work, a slotted typeplate disposed on the head so that the row of characters on the type-Wheels passes through the slot of the type-plate, said plate having characters flush with the row of characters on the wheel, said head being provided with a fixed jaw anda movable jaw arranged to receive and retain the edges of said type-plate, and a retaining bail passing over a fixed projection uponthe type-head with its ends bent and attached to the ends of the type-plate adjacent to the fixed jaw,

said bail being constructed and arranged to support the type-plate in a position suflici ently separated from the type-wheels, when,

the type-platehas been released by opening the movable jaw, so that the type-plate will not interfere with the adjustment of the type-wheels.
