CARD-FEED-ACTUATED STOP.

Specification of Letters Patent.

Patented Sept. 30, 1919.

. To all-whom it may concern:

Be it known that I, JAMES POWERS, a citizen of the United lStates, residin in New York city, in the county of New ork and State of New York, have invented certain new and useful Improvements in Card-Feed- Actuated Stops, of which the following is a specification.

This invention relates to perforating machines and more particularly to mechanism for automatically stopping the operation of perforating machines.

The-main object of this invention is to provide a stop -mechanism or power cutoff for arresting the operation of a perforating lmachine whenever a card is not discharged from such machine.

This lack of discharge may be due to the fact, that the supply of cards to be perforated has been exhausted, or else that the card has been arrested or stuck in the machine before passing therefrom. In either event, it is desirable that the perforating machine be stopped since the continuation of the operation would only result in a loss of power. n

A specific object of the inventionis to provide a means for shutting off the electric power of electrically operated perforating machines. g

A further object ofthe invention is to provide means whereby the stopping means, af-

. ter having performed its stopping operation may with facility be reset to be in position to stop the machinewhen next required after the machine has been again set into operation. l

And another object of the invention is to provide a stopping mechanism for any machine from which cards or the like are discharged, especially perforating machines, althoughin the accompanying drawings the stop mechanism is applied only to one particular form of perforating machine.

Still another object of the invention is to provide such a stopping mechanism .which can be readily a plied to any machine from which cards or the like are discharged with- 'out requiring any expensive reconstruction.

one specific embodiment thereof illustrated in the accompanying drawings in which- Figure 1 is a side elevation of a perforating machine equipped with the stop mechanism.

Fig. 2 is a plan view of the same, parts being broken away for the purpose of illustration.

Fig. 3 is a longitudinal section along the line 3-m3 of Fig. 2 and looking in the direction of the arrows of such line. I

Fig. 4 a fragmentary perspective showing the stop mechanism with parts of the perforating machine removed therefrom.

Figs. 5 and 6 are longitudinal and transverse sections respectively of the switchmechanism. y Fig. 7 is a detached perspective of a portion of the switch mechanis Fig. 8 is a fragmentary view of a portion of the stop mechanism. y

In the embodiment illustrated there is provided a frame 1 having a bracket 2 `extending from one end thereof on which is supported a card receptacle 3 having a reciprocating slide 4 forming the bottom of said receptacle by means of which slide the cards sup orted thereon are fed into the machine to t e perforating mechanism one at a time, the slide 4 being connected to a lever 5 pivoted to the bracket 2 and connected by a link 6 to a cam link 7 pivotally connected to of which camtlink 7, link 6, and lever 5 the slide 4'is reciprocated.

From the slide 4,-the cards, one at a time, are fed to the first set of feed rolls -9 suitably mounted in the frame 1, from such feed rolls 9 to the pin box between the guide plate 10 and die plate 11 suitably mounted `vei` 14 pivotally mounted in the frame 1 and having its other end in engagement with the cam. 15 on the driving shaft 8, by means of which cam 15 and lever 14, the frame 12 is raised, the raising being timed to take place when 4the card is supported between the plates 10 and 11 on said frame 12.

Above the movable frame 12, is fixed on the fra-me l, a perforated plate 16 provided with a series of perforations in each of which is slidably disposed a pin 17 having` a head 18 larger than a perforation and supportingr the pins in said plate 16, the lower ends of said pins extending into a correspending series of perforations in the guide plate 10 and disposed iopposite to another cprresponding series of perforations inthe dle plate 11, the arrangement being such that when the pins are obstructed in their upward movement, and the guide plate 10 and die plate 11 are moved upward with the movable frame l2, the series of pins will be permitted to extend into the series of perforations in said die plate V1l, the perforating of the cards being effected/by such obstructed pins, while the ins unobstructed' will ride on the surface o the card and. rise with the movable frame 12.

From the guide plate 10 and die plate 11, a card, after having been perforated, is fed to -the'discharge rolls 19 from which they are discharged into the discharge receptacle 20A positioned at the rear end of the frame 1 and supported on a bracket 21 secured to the frame 1, the end of the'frame where the receptacle 3 is disposed being designated the front of the machine for purposes of explanation.

In the present instance, provision is made for gang punching the whole card. This is done when a number of cards are to be punched with Vthe same data in which case,

tire-required pins are set and locked in position. For this purpose, a perforated plate 22 having a series of perforations to correspond with the series of perforations in the fixed Vplate 16, is supported on arms 23 secured to the fixed plate 16 in which plate 22, setting pins 24 are positioned having heads 25 to support them on the plate 22 which pins 24 are positioned according to the data to be perforated, reproducing the record on said plate These pins 24 are locked in position against upward movement by means of a locking plate, 26 which in the present instanceJ is hinged to the front end of the plate 22 and provided with thumb screws 27 to register with openings in the plate 22 when the locking plate 26 is in locking position and are adapted to engage such openings in plate 22 having screw-threaded connection with the same and thereby lock the plate 26 in place on the plate 22, the distance the plates 22 and 26 are spaced from one another being equal substantially to the altitude of the heads 25, the plate 26 being adapted to rest on such heads 25 and thus lock the pins 24 in'position. Thus when the setting pins 24 are set to reproduce the data to be perforated, and cards are fed through the machine onto the plate 11, the upward movement of the frame 12 will raise the card with it ,and the perforating pins 17 that are unobstructed will ride on the surface of the card, while those pins 17 that are unobstructed by setting pins 24 will punch through the card and pass into perforations in the die plate 11. Upon the descent of the movable frame 12, the intermediate feed rolls 27 will feed the' card from between such pla-tes 10 and ll to the discharge rolls 19 from which the card is discharged into the discharge receptacle 20.

The foregoing is one of the perforating machines to which the stop mechanism, or power cutoff now to be described, is, in the present instance, attached. Extending rearwardly from each side of the plate 16, and in the'present instance integral therewith, is an arm 28 provided with a bearing 29 in its free end. Carried by the bearings 29 of these arms l88 is provided a rock shaft or rod 30 to which are fixed three downwardly extending arms 31 which extend down rearwardly of the discharge rolls 19 into the path of the card being discharged from such discharge rolls 19. At one end of the rod 30 and preferably extending at an angle to the direction of the arms 28, there is fixed a lever 32, the free end of which rests on the arm 33 of a bell crank pivotally connected to the upper end of the upright frame 35 formed on the cylindrical conformation 36 which, in the present instance, is formed integral with the frame 1 and extends laterally therefrom. The cylindrical conformation 36 is provided with a slot 37 into which the downwardly extending arm 38 is adapted to move when the arm 33 of the bell crank is depressed, the bell crank having an extension 39 extending in the opposite direction to the arm 33 to which is connected one end. of a tension spring 40, the other end of wlnch is connected to the pin 41 fixed to the lateral extension 42 integral with arid formed between the frame 1 and the cylindrical conformation 36, this spring serving to ynormally maintain the arm 38 out'of the slot 37 in the cylindrical conformation 36.

In the cylindrical conformation 36 is dlsposed a plunger 43 having av centrally disposed opening 44 partly extending therethrough in which opening 44 is slidably mounted a rod 45 having a key slo't 46 to accommodate the pin o1' key 47 fixed transversely of said plunger 43 and partly extending through said opening 44. On the rod 45 is secured a sleeve 48 between which sleeve and the front end of the plunger 43 isrstrained a spring 49. Forwardly of the sleeve 48 is formed a bearing 50 in the present instance integral with the bracket extending from the frame 1 in which bearing the rod 45 slides extending therethrough and having a forward extension on which is formed a sleeve between which sleeve and the bearing 50, there is strained a spring 7l to normally maintain the rod 45 in forward position. Forwardly of the sleeve 70, the rod is bent at two places and is provided with a roller 51 at its front free end which roller 51 coperates with a cam 52 on the driving shaft 8. Below the cylindrical conformation 36, there is formed. a bracket 53 Vim on the-end of which is provided a bearing 54 to which is fulcrumed a lever 55 having a broad upper portion 56 extending in front of the opening in the cylindrical conformation 36 the lower end of which lever 55 extends down and coperates with a cam 57 on a' disk 58 mounted on a shaft 59 which extends through and is carried by a bracket or housing 60, and having a knurled .knob 61 secured to its free end extending rearwardly through the bracket 60. The broad portion 56 of the lever 55 is normally maintained directly in front of the opening in the cylindrical conformation 36 by means of a', spring 72 connecting such 'broad portion 56 with a pin 73 formed on the lower portion of the cylindrical conformation 36. The bracket or housing 60, in the present instance, is formed on the framel and is shaped to accommodate a druin 62 fixed to the shaft 59 which drum has in one of its ends (Figs. 5 and 6) a cylindrical opening surrounding the shaft 59 in which is disposed a spring 63 attached at one end to the housing 60 and at the other end to the drum' 62 and adapted to control the movement of the drum 62 with respect tothe bracket 60.

Extending through the upper portion of. the bracket 60 are two terminals 64 and 65 of an electric circuit which are each extended outwardly by a spring 66, see Fig. 5, to

impinge against the drum 62. The drum 62V is provided with a conductive plate 67 eX- tending longitudinally thereof. and of suir cient length so that when the drum is rotated so that this plate is disposed adjacent to the terminals 64 and 65, the terminals will each be in contact with the conductive plate 67 and thus complete a circuit, the terminals bein connected by suitable mains 68 and 69 to t e driving motor and source of supply.

The operation is as follows:

Every time a card is discharged from the discharge rolls 19 it will strike against the downwardly extendin arms 31, rock the rod or rock shaft 30 t ereby depressing the arm 32 which in turn will depress the arm 33 and the arm 33 rock the bell crank so that its downwardly extendin arm 38` will enter l the slot 37 inthe cylin rical conformation 36. When the arm 38 is depressed into the slot 37, the cam 52 will be so timed that it will at the discharge of a card engage the roller 51 and thereby actuate the rod 45, the rod will advance the plunger 43 against the arm 38, the plunger 43 being there prefYented from further movement, the rod 45 will move `into the openin 44 compressing the springs 49 and 71. pon the further rotation of the cam 52, the rod will be permitted to be returnedv to forward osition which is effected by the splring 71 w ile the spring 49 will prevent -t e ll lturning with the rod 45; an

the spring 40 (plunger 43 -re- 'ply being exhausted, or due to a card stick- 1ng 1n the. machine, the arm 38 of the bell crank will not be moved into the slot 37 to obstruct the plunger 43, and consequently when the cam 52 in its rotation actuates the rod 45, the rod 45 by means of the spring 49 will advance the plunger 43 through the opening in the cylindrical conformation 36 into contact with the upper portion 56 of the lever 55, andstrike such upper portion, the lower end of whichdever having inthe meantime been disposed against the cam 57 of the disk 58, maintaining the shaft 59 with its contacting plate 67 in contact with the terminals 64 and 65 against the tension of the spring 66. ,Upbn striking the lever 55 its lower end is removed from the cam 57, freeing such.l cam 57, and the spring 66 in the drum 62 will rotate the drum 62 to remove the conductive plate 67 out of contact with the terminals 64 and 65 thereby breaking the circuit.

' Upon further rotation of the cam, the rod 45, will, of course, be again returned to normal position, and to then start the machine into operation again, it is only necessary to turn the set screw` 61 so that the conductive plate 67 contacts with the terminals 64 and 65, in which position, the cam 57 on the disk 58 will again be impinged against the lower end of the lever 55.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention.
