Specification of Letters Patent. I

Patented Feb. 2, 1909.

Application filed March 2, 1907. Serial No. seams.

claims I mean to include any other mechanism which in view of the prior art may be considered equivalent devices.-

For the purposes of clear illustration and descri tion, and those alone, I have shown embo' ied in the invention art of the mechanism described illustrate and claimed in U. S. Letters Patent N 0. 627,256, dated June 20, 1899, for card punching machines, granted to The Kursheedt Manufacturing Company, as my assignee.

The invention will be understood by referring to the accompanying drawing, in which p Y Figure I is a broken away side elevationfof a machine embodying my invention, and

Fig. II is a similar side elevation showing the parts in different positions.

In the drawing the frame of the machine is indicated generally by the letter A, and the unching mechanism is indicated generally y the reference letter B.

C and D are feed rolls or propelling mechanism for the card E which is punched by the punching mechanism, or acted u on or cooperated with in conjunction wit the feeding mechanism by other mechanism which may replace thepunching mechanism. In this specification, "I will include within the term unehing mechanism, such mechanism as cooperate with the feeding mechanism, or feeding device 0 D to perform some function in connection with the card, which in the strip suc as is shown in the drawing.

In the drawing, G indicates generally-the take up mechanism, located behind the feeding device, and F indicates generally the feeding roll or let off roll. For the urposes of this specification, the take up rol and the let ofi' roll may be regarded as equivalent in a sense, and the term synonymous in asense,

to the punching or feeding devices.

resent case, expressly includes a in that in'the present instance they are both actuated by somewhat similar mechanism.

The Jacquard card E passes from the roll F and falls in a loop, passes over the roll 1,

the apron 2, the roller 3 and through the take up G. A gravity sto'p pawl 11 is provided to resent a reverse movement of a take up 1'0 1 G. The let ofi roll F is provided with a shaft 12 having a ratchet 13, with which cooperates a gravity impelled pawl 14 carried by a rod 15 on an eccentric strap 16, cooperating with an eccentric on a shaft 4. It will be obvious that the normal operation of the ,two pawl and ratchet mechanisms will be to cooperate with the feeding device C D in repelling the card or strip, the take up rol G serving to take up the card or strip as it comes from the feeding devices, and the let off roll F servingto supply'the card or strip It some times happens however, that the take up roll G will operate too rapidly for the feeding devices, and tend to cause an'undue tightening on the card between the feeding device and the card take up. I therefore provide 1 means for obviating this difficulty.

Located beneath the arm 7 is an arm 17 pivoted to a stud 18, and connected to an arm 19 also pivoted to the same stud. I At the lower end of the arm 19 is an arm 20, having at one end a spring connection 21 with the frame A of the machine and at its other end a pointed nose 22 adapted to cooperate with a pointed cam 23, carried on a s aft 24, and connected to an arm 25, carrying a roller 26, which bears upon the web, card, or st 'p E. .Q

In theFig. I, I have shown the web as having the proper amount of slack and the 'pawl 8 engaged with a ratchet 9, so as to effect a step-by-step movement of the take up G. In ig. II, however, for some reason or other, the web has become taut and has raised the arm '25 thereby permitting .the cam 23 to swing to the right as shown in the said figure, and allowing the arm 20 to be sprung to the -left-thereby bringing the arm 17 beneath the rod 7, and lifting the pawl 8 clear of its ratchet so as to prevent rotation of the take meet this dificulty I haveprovided means forintermittently feeding this let off roll positively. For the purposes of the present case I provide a lever 27 pivoted. at 28 on the frame of the machine, and provided with a yoke 29 which surrounds or embraces the rod 15, carrying the pawl 14 and which lever 27 is provided at its free end with a roller 30,

--adapted to cooperate with the web E as shown in'the drawings: The pawl it is normally out of contact with its ratchet 13, that is to say in the present instance, it is so shown.

When the web is running freely and there is no trouble, the roll will have a slight movement to permit the feed or let off. When the web becomes tight, as shown in Fig. II,.the lever 27 is swung allowing the pawl 14 to go into engagement with its ratchet 13, and efi'ect the forward feed of the web to supply the necessary slack.

t will also be observed by reference to Fig. II, that both the take up and let off motions may be operated simultaneously or dissimultaneously, but in the particular machine shown, the feeding devices absolutely govern the movement of the web, and indeed in any machine employing a web for a useful urpose, a normal positively regulated 'eed should be employed. In the present instance, the punches I) of the punching mechanism punc holes at the edges of the strip or web, into which the spurs 0 enter and ass through into the recesses d in the lower r0 ler, so that a positive forward motion is produced, and a card is punched fit for use in jacquard mechanism disclosed in U. S. Letters Patent No. 528,632, dated Nov. 6, 1894:, for jacquard mechanism. J

Having described my invention what I claim as new and desire to secure by Letters Patent, is
