A main object ofthe present invention is machines, 7 i c a a With such an object:-+ c

The .inventionzconsists in the combination of elements hereinafter; described and particularlypointed: out in the claims-L "to increase the: .1working':'speedi ofsuch The invention, will now: be described with j V responding to the possible x total number of holes in arecord card.

' Each set bar, hisof a" particular forniation asg'shown inFigure 3,- having on one "'side'a project-ion,l3, thetop, 14,015 which is liorizontal',=the side, 15, vertical and. the bottom, 5,16,; sloping downwards at an angle of about ---to join the1b'ar. The other side of each set baryfl, has arecess, 17,1the top;-18,- of whichlis: horizontal, the side, 19, vertical; and thev bottom, 20; sloping clowning bar, 22, WhlChflS orm'eol 'bya vertical plate having a. number ofsmall horizontal .projections,l23, on its lower edge: one' for, 7 each set bar, which projections co-fact with wardsjat the same anglefas fthe' bottom, 16, d on the oppositeside, thetwo slopingrportions,

always tend to move away fromthe .projec tions upon theset bars. The locking bars arecarried by the frame of the pin-box and are reciprocated up and down therewith;

the continued descent of the pin-box brings the projections, 23, on the locking bars in contact. with the sloping portions,.20, and

moves the locking bars to the right in Figure 2, so that the projections,"25, slide over the tops ofthe projections, 13, on the set bars which have entered perforations, Further descent ofthe pin-box will press the set bars 1.3, on the set bars. In the bottom: perforated plate, I, on which the masterrecord rests are situated a' number-of intermediate pins, 26, the lower upon-the heads,.2,' of the sensing .pins, .1,

through direct contact of the projections, 23,

onlthe locking bars, 22, with the. projections,

ends ofwhich are reduced. in diameter and rest upon the heads, 27 of punches,.28,s1tuated in thevpunching-pi'n box, the heads. of

the punches'resting upon ahorizontal plate, 29, attachedto the pin-boxiand forming'a guide, suitable guides, 30 and 31, also being provided for the intermediate pins. The

' bottom ends of the punches, 28, are located in the top perforated plate, J, between which and the bottom perforated plate, J, the blank cards-to be punched are placed. 1 g Each locking bar, 22, is provided with a locking latch or pawl, 33, pivoted on a rod, 34, secured. to the frame of the pin-box. When a pawl, 33,.is placedinthe portion shown by-dotted lines'it enables any sensing pinsto be cutout from functioning asv for instance the seven pins shown onthe rightof Figure 2. It also enables any number of pins to be used. forpunching holes at every stroke of the machine as for instance the live sensing pins shown on the left of .Figure2. Any combinations of these-two functions may also be obtained.

.Inoperation the cards are between the perforated plates, I and J, and the upper and lower pin-boxes while the rotation of the eccentric slowly brings the two pin-boxes down to their lowermost position. As all the potential rows of perforationsare'sensed the sensing pins, 1, pass through the holes in thecard and the further descent of the pin-box moves the lockingbars, 22, so as to lock these pins intheir downward position by means of the sensing pins which have not enteredfperforations in the card, as ex presses them upon the heads of the punches which are thus thrust through the cards and perforate them in thedesired position.

Upward movement of the pin-boxes restores the punches to their normal position and raises the intermediate pins and sensing The sloping part ofthe'recessesof the set bars is so arranged that when the pin-box' descends and the two sensing pins which. do not enterperforations rest upon the card,

pins'as well asthe set bars,'until in'the final position the locking bars are restored by the springs, '24, to their normal position, un-

locking the sensing pins which passed through. the perforations by means of the projections on the locking bars sliding back into the recesses, 17, on the set bars. Just before the pin-boxes have attained their highest positionthe cards are ejected by means of rolls and are fed into hoppers,

'VandY'a 1 It will thus be seen that a duplicate of the master card is producedat one single operation and that the sensing pins themselves act to operate the punches directly.

duction of-each master record is produced but any number of reproductions can be madeby having one or more master records and continually feeding them in to the sens ing device. 1

It is to 'be'understood that the invention is equally applicable to producing Jacquard loom cards, rolls for-piano players or the like having perforations.

Having now described my invention what I claim as new and desireto secure by Lettors-Patent is l. 'Apunching machine'for duplicating a perforated card of the kindindicated, comprising in combination a pattern card; a
