MACHINE FOR PUNCHING HOLES IN JACQUARD CARDS.

SPECIFICATION forming part of Letters Patent No. 445,340, dated January 2'7, 1891.

Application filed April 21,1890. Serial No. 343,808. (No model.)

To ctZZ whom it may concern.-

Be it known that I, OTTO V. SCHAUM, of the city and county of Philadelphia, State of Pennsylvania, have invented a certain new and useful Improved Machine for Punching Holes in Jacquard Cards, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to machinery for punching the holes in Jacquard cards; and has for its object to improve such machinery and render it more easy and convenient to operate.

My improvements will be best understood as described in connection with the drawings, which illustrate the construction of a machine embodying them, and in which- Figure 1 is a perspective view of the said machine. Fig. 2 is a perspective view of the rods or punches used to force the lockingbolts back to an inoperative position, and their attachments. One of the punches which operate upon the card, the bolt which secures the said punch in operative position, and the key by which the bolt is operated are also shown. Fig. 3 is a plan view of myimproved machine, taken on the section-line 1 y of Fig. 5, or along the top of plate D, said plate bein g also broken away, as indicated by sectionlines, to show some details of construction. Fig. 4 is a side elevation of the machine, taken on the line it w of Fig. 5; and Fig. 5 is a front elevation taken on the line 00 00 of Fig. 4.

A is the frame of the machine; A, the table before which the operator stands; B B, plates secured one above the other, and having a recess 11 formed between them to receive the cards. .The plates B and B are perforated, as shown at h and b, so as to permit the punches to pass through them.

As shown, the plates B B are secured together by means of the threaded bushings O C, and they are fastened to the pad or frame of the machine in any convenient way.

D D are two iron plates, which together form the movable head of themachine. This head is formed with a series of vertical perforations d d, corresponding in position with the perforations b l) in the plates B B. The parts (1 of these perforations are smaller in diameter than the parts (Z. Sockets (Z are formed at each end of the movable head to receive punches, which are secured therein so as to always move up and down with the movable head. Leading into the perforations (Z are two series of horizontal perforations or holes, one series, indicated by the letters (Z leading from the back of the movable head, and the other series, indicated by the letters (1, leading from the front of the movable head.

As shown, the two plates D and D are secured together by means of the guide-rods E E, which pass through perforations d d in the said plates and clamp them together by means of the rings 0, resting against the lower plate D, and nuts c,screwing on threaded ends of the rods E and pressing against the upper part of the plate D. These guide-rods E move in the bearings C of the lower head B B, keeping the movable head in line with it. Horizontal perforations d d are also formed in each end of the movable head, for the purpose hereinafter describod. The movable head is actuated by means of pitmen or connecting-rods F F, secured to it, as shown, and the cams G G, attached to the driving-shaft H. The shaft II is driven by thepulley I and clutch J. The said pulley runs loosely upon the shaft II, except when the clutch J is actuated so as to connect them.

' I have not thought it necessary to describe the construction of the clutch shown, as any convenient clutch may be used and arranged so as to normally disconnect the pulley and shaft and to connect them only when the clutch-actuating device such as is indicated at J is operated.

K K, &c., are the card-punches formed with an enlarged head and proportioned so that the punches will pass freely through the perforations cl, while their heads will rest upon the rim formed between the perforations d and its enlarged continuation (Z. The portion at of the perforation is sufficiently long to permit the punches to. move up in it for a distance suliiciently great to prevent their ends passing through the slot b when the movable head is in its lowest position.

M M, &c., are bolts, which are inserted in the perforations (i in the movable head.

They are formed with an offset m, which, by engagingwith abar m securedacross .the lower part of the perforations (1 will prevent them coming out of said perforations, and in order to prevent them from moving too freely in the perforations, I form in each belt a recess m, in which I place a light spring m which presses against the upper part of the perforations (Z and serves to steady the bolt therein.

L L, &c., are rods which pass through the perforations (Z in the back of. the movable head and at their rear ends are secured to a bar L, from each end of which rods L L project and pass through the perforations d in themovable-head. On the end of the parts L 'ofithese rods, which project to the front of theh-ead handles L are secured, and about said .partsi L, which are, as shown, smaller than theparts L spiral springs L are secured whichq act-to press the rods-and the bar L,.which .they' carry, backward.

z-To the extent above described the machine in its general features is old, and my present invention consists of the hereinafterdescribed improvements upon the said machine. To the. upper part of the movablehead I secure-one or. more rodsn n,-preferably two, arranged one-in'front of the other, as'shown. They are attached vto the movable head by means of the brackets N N, and I pivot upon these rods keys 0 O,.the lower ends of which rest. .against the ends of the bolts M, while theirinpper ends are properlyformed-to enableerthem to be -operatedas, for-instance, like a1type-writer.and it is preferable-to arrange these keys on the rods n n alternately, so-as to give them thestaggered arrangement shown, by which the apparatus -:is rendered more compact and more easilybperated. Each. of the. keys will of'course be marked to indicatethebolt and punch which it controls.

The operation of the machine is as follows: The operator sets the machine for the work itisto perform by pressing down upon the keys which govern the punches which he desires to bring into operation. Each key, when pressed, pushes its corresponding bolt until its inner end-extends across the topof'the perforation cl and above the head k of the punch contained in said perforation. The desired pattern of the card having'thus been provided for, the operator slips a blank card into the groove b and-then by actuating the clutchlever J connectsthe driving-pulley I with the shaft H, so as to rotate said shaft, and by means of cams G and connecting-rods F draw down the movable head. As-the head moves down, the punches K of course move with it until they come into contact with the blank card,when those punches over which the bolts M extend pass through the card, while those which are not bolted are free to rise in the perforation d, and do risetherein as the movable head descends, making no perforation claim as new, and desire to secure by Letters Patent, is
