VJORK-EJECTING MEANS FOR PRINTING APPARATUS.

Application filed December 13, 1923. Serial N0. 680,419.

To all whom it may concern:

Be it known that we, W'AL'rEi-i B. PAYNE and FLOYD A. GREENE, both citizens of'the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in WVork-Ejecting Means for Printing Apparatus; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference numerals marked thereon.

This invention relates to printing apparatus, and more particularly, to the variety comprising mechanism for ejecting the work from the machine after it has been, printed, one object of the invention being to provide a machine of this character comprising a simple and efficient ejecting mechanism brought into operation automatically at the completion of a printing operation in the normal manipulation of the machine, together with automatic means for terminating the action of the ejecting mechanism after a-uniform period of action sufficient to complete the ejection of work of a given range of size. Another object is to provide such an apparatus with a reliable and inexpensive form of ejective mechanism the operation ofwhich, after being started, is continued and automatically terminated by a feeding coaction between parts of the mechanism. A further object is to provide a printing apparatus having a manual control or type selecting means and a driving means and an ejecting mechanismbrought into operation by the control means and driven by an actuating connection with the driving means for the apparatus, To these and other ends the invention consists in certain improvements and combinations of parts, allas will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

Similar reference numerals throughout the several views indicate the same parts.v The invention is embodied in the present instance. in conjunction with a printing apparatus of the variety shown and described in the copending application of Walter B. Payne, Serial No. 674,208, filed November 12, 1923, for motor drivenprinting machines, so that but a brief description thereof sufficient for an understanding of the present invention is required herein.

The printing apparatus comprises a base portion 15 the top 16 of which forms a bed for supporting the work during the printing operation and on which is mounted, an upper casing portion 17. Journaled at its ends in the opposite vend walls ofthe latter is a main shaft 18 on which is splined for longi tudinal sliding movement a carrier 19 of gen erally cylindrical shape provided with a plurality of longitudinally spaced, circumferentially extending type forms 20 adapted to be brought by a longitudinal shifting movement of the carrier selectively and individually to printing position opposite arotatable platen Wheel 21 supported on the base. This selective movement of the carrier is effected by a yoke 22 having at its ends arms sliding on the main shaft and embracing the ends of the carrier, the yoke being held against rotation by any suitable means. For moving the yoke the latter carries a bracket 23 projecting through a slot in the casing and having fixed thereto a. manual control member or handle 24. The bracket carries also a. pointer 25 movable over a dial 26 on the casing, marked with representations of the separate type forms, so that by moving handle 24 to register the pointer with any one of the dial characters the corresponding type form is positioned for printing The printing of the selected type forms s accomplished by an intermittent rotation of the main shaft and carrier ialternating with the selective movement already described. Such actuation of the main shaft is accomplished in the present instance by a driving motor 27 mounted on the casing and connected by gearing, as fully disclosed in the said copending application, with a gear 28 rotating on the main shaft. This gear is intermittently clutchedlto the main shaft by control means connected with handle 24 and including an automatic trip means indicated generally at 29, the particular construction of which however forms no part of the present invention. It may be stated however that in addition to its selective movement longitudinally of the machine, handle 24 has a slight rocking movement with the yoke about the main shaft and such movement of the handle, after the selection of the type form, clutches gear 28 to the main shaft. After a complete rotation of the latter and the type carrier the driving connection with the motor is tripped andv the carrier comes to rest for selection of the succeeding type form.

The platen wheel 21 is rotatably mounted between the arms of a yoke 30 fixed on a shaft 31 rocking in suitable bearings on the base below the work bed. The platen normally lies below the latter and is raised through an opening therein by an arm 32 fixed on shaft 31 and engaging a cam 33 on the main shaft so arranged that during each rotation of the carrier, as the selected type form approaches the platen, the latter is raised to press the work against the type. The rolling cooperation of the platen and type thus simultaneously prints and feeds the work through the machine, as the successive type forms are selected and impressed, to complete a desired legend.

Preferably the apparatus comprises means for holding the work on the printing bed against inadvertent movement and for guiding the same during the printing operation, comprising one or more rollers 34 rotatably supported on a carriage 35 pivotally mounted on an arm 36 fixed on a rock shaft 37 in suitable bearings on the base. A spring 38, Fig. 3 connected with shaft 37 and with a bracket on the work bed normally rocks shaft 37 so that rollers 34 are elevated through an opening in the work bed to press the work against a plate 39 on the casing, to thus yieldably hold and guide the work, it being understood that the latter is inserted in the machine through a slot in the casing at one side of the latter and delivered through a corresponding slot on the opposite side as shown in Fig. 4. For inserting and removing or ejecting the work, a means is provided preferably connected with control member 24 for lowering rollers 34 out of work engaging position. It is to be noted that the end character of the dial 26 is the word Release and when the carrier is shifted by bringing pointer 25 over this character, the end 40 of the carrier yoke, Fig. 1, is brought against the beveled end 41 of an upright terminal portion 42 on a horizontal transverse extension '43 of rock shaft 37. The connection thus established between control member 24 in this position and the rock shaft servesito actuate the latter to lower the rollers out of engagement with the work to free the same for ejection from the machine. It is apparent from the above description that handle 24 is moved to register pointer 25 in succession with the type forms composing the legend to be printed and after, the selection of each type form, the handle is depressed and con nects the driving motor with the main shaft, to give the latter and the type carrier one complete rotationduring which the platen is raised to press the work against the selected type form as the latter rolls past. The work is thus successively printed and fed and when the legend has been completed the control member is moved to Release position to free the work for removal or ejection from the machine.

The ejecting mechanism is combined with the above apparatus for operation thereby during the normal use thereof without requiring attention on the part of the operator. This mechanism or device comprises. in the present instance, a pair of work feeding parts or rollers, one located above and the other below the work bed opposite the printing point at the discharge side of the machine. One of these rollers, and preferably the upper roller 44 journaled on a bracket 45 on the casing, is connected with the motor for driving the apparatus so that it is continuously rotated during the use of the machine. To this end the shaft 46 on which the roller is mounted is continued, as shown in Fig. 1, to the rear of the machine adjacent the connection with the motor. This portion of the shaft has fixed thereon a gear 47 meshing with an idle gear 48 en-- gaged with a gear 49 fixed on a sleeve 50 rotating on the main shaft and driven the continuously rotating gear 28 to wh ch itis attached. I

Roller 44 is so positioned that it is normally above and out of contact with the work and oneofthe rollers, preferably the lower roller 51, is movable toward and from roller 4:4, through an opening in the work bed, to engage and feed the work therebetween, it being apparent that the c-jectlng mechanism is normally disengaged from the work and inactive, being brought into operation by elevating the lower roller 51 the return of which to lower position terminates the ejecting action of the mechanism.

The movable or lower ejecting roller is preferably raised by an actuating connection with the control member 24 when the latter is moved to the Release position, as already-described, so that the ejecting action is started simultaneously with the release of the work from the rollers 84:. lhis portion of the mechanism comprises a bracket 52 on a side wall of the base carrying a spindle 53, Fig. 9. Loosely pivoted on the spindle is a yoke 54 between the spaced arms of which roller 51 is journaled. Fixed to the roller and projecting beyond one of the yoke arms isa camming element of part 55 in the form of a helically or screw threaded stud which is of course rotated by the rotation of the roller during the ejecting action. Loosely pivoted on spindle 53, and spaced therefrom by a sleeve 56, is an angular arm 57 extending downwardly and inwardly of the machine and then turned longitudinally thereof as at 58. Pivo-ted on the portion 58 at 59 is an element or part 60 the upper end of which is toothed or grooved as at 61 to mesh with the threads of the cannning element 55. Element 60 is normally urged by a spring 62, coiled about its pivot with one end applied thereto and the other arm 57, to the position of Fig. 5 in contact with the roller yoke below the threaded element 55. It is apparent from this construction that, by swinging arm 57, element 60 may be raised to engage element 55 and thus elevate the roller for ejecting engagement with the work and that the rotation of the roller will cam or feed the element 60 out of engagement with element 55, as shown in Fig. 8, so that the roller may drop by gravity to inactive position. The means for thus swinging arm 57 to start the ejecting action comprises a rod 63 having a pivotal and adjustable connection with the arm, as shown, and pivotally connected at its other end with an arm 64 fixed on shaft 37. The locking of the latter therefore by the control member 24 serves to elevate the lower roller to start the ejecting action. After a predetermined period this actuating connection with the roller is disestablished or tripped by the feeding action of the elements 55 and 60 and'the ejecting operation is automati--' cally terminated. p

In case work of unusual length or character is to be printed, it may be desirable to temporarily disable the ejecting mechanism and to this end element-60 has'pivoted thereto, at 65, a dog 66, having a shoulder 67 arranged for engagement with a side of arm 57 against the tension of spring 62 which serves to retain it in this position and such manipulation of the dog moves and holds element 60 in the inactive position shown in, Fig. 7, which temporarily places the mechanism out of operation,

The operation of the apparatus has already been explained in connection with the description of its construction and it is ap parent that the control member or handle 24 is successively moved to register its pointer with the characters representing the type formsto be printed. .After each such selection of a type form, the handle is rocked to produce a printing rotation of the type carrier and after the desired legend has thus been completely printed, handle 24 is moved to the Release position, which frees the work from the guiding means and, through the connection described, raises the lower ejecting roller to press the work against the rotating upper roller and thus feed it from the machine. This action continues until the parts 55 and 60 are fed or camme d out of engagement with each other, when the lower roll drops and the operation terminates. The length or pitch of thread of thepart 55 may obviously be proportioned to' suit the length of a check or other work for which the machine is normally employed, so that such work is fully ejected from the machine. The relatively small check or other paper form handled by apparatus of this character has sufficient inertia after being given an ejecting movement as described to carry it I on to a table or stacking tray such as indicated at the left in Fig. 3 for conveniently disposing of the work.

The invention thus provides an exceeding ly simple and reliable and at the same time automatic means for ejecting the Work 0-peratedby the parts of the apparatus in the normal use thereof for printing so that no attention on the part of the operator or any additional operation is required and while the modification of the invention herein disclosed has been found practical and eflicient in use, it is obvious that various other details of construction and operation may be employed within the scope of the appended claims and that the mechanism may be combined with various other types of printing apparatus.
