PIANO CARD-PUNCHING MACHINE.
SPECIFICATION forming part of Letters Patent No. 742,170, dated October 27, 1903.
Application filed April 23, 1903. Serial No. 158,882. (No model.)
To all whom it may concern:
Be it known that I, J AMES B. DAVIDSON, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain newand useful Improvements in Piano Card-Punching Machines, of which the following is a specification.
My invention has relation to that class of card-punching machines known as pianomachines, in which rows or banks of punches are arranged under control of levers or pushkeys; and in such connection it relates to the construction and arrangement of the mechanism controlling the punches of such a machine.
In machines having more than eight punches for use in punching cards with regular and irregular holes it was customary to provide each punch in series with a separate key or lever controlling the locking of the punch to the head carrying all the punches. I
In such a construction the manipulation of the keys was an intricate and a difficult operation, requiring skilled operators and keen oversight to prevent mistakes. Again, it was customary to have in the head a single punch for punching the peg-holes of the card, and where the holes were to be punched at the beginning and ending of the card with this single peg-hole punch it was necessary to shift or manipulate the card so that the punch usually punching a back peg-hole couldpunch the front peg-hole. This shifting or manipulation of the card was a, delicate operation, requiring also skilled operators and a keen oversight of the work.
The principal objects of my present-invention are twofold. First, there is provided a single lever or push-key, which by a simple adjustment may control either oneoftwo ad- .jacent punches or may control both of said .ner.
With such an arrange-v trolled by a special key back of the regular punch keys or levers. With this additional key the accurate cutting of the back peghole may be obtained by a comparatively unskilled operator without a shifting of the card in the machine.
The nature and scope of my invention will be more fully understood from the following description, taken inconnection with the accompanying drawings, forming part hereof, in which- Figure l is a horizontal sectional view 0 the head or block of a piano card-punching machine, illustrating the regular punches and the levers or push-keys controlling the same,
the mechanism shown embodying main features of my invention. Fig. 2 is a rear elevational view, partly sectioned, of the head or block and auxiliary parts. Fig. 3 is a vertical sectionalview on the line 3 3 of Fig. 1. I
Figs. 4 and 5 are views corresponding to Fig.
3, butillustrating certain adjustments of the 1 illustrated.
The head or is attached to the machine by the rodsa and operated in the usual manstruction itis formed of two blocks clamped together by the rods 0t and nuts 0. .011 said rods. On the under surface of the top block a is cut grooves or channels a, which are square in cross-section, and in these grooves are located the levers or push-keys b. In the lower block 0. are supported in any wellknown manner the series ofpunches d and the front peg-hole punch 01 and rear pegshole For the sake of convenience of conpunch (1 which exteud-from-the block at. I
right angles to the lovers or keys "b. In the drawings the punches d are illustrated'as sixteen in number, the keys or lovers 1?) being one-half that number, oneight in all. The
head a is vertically slotted, as at at, for a purpose hereinafter described. Each key I) is substantially square-shaped in cross-section and has at its inner end a rectangular projection b, as clearly illustrated in Fig. 7. By turning the key or lover I) and inserting it into a channel a, so thatits inner rectangular end projects into the path of two adjacent punches d, the key or lever b may be used to lock both of said punches to the head a, as illustrated in Fig. 4, or when turned one hundred and eighty degrees and then inserted into the channel a the rectangular end I) may clear both adjacent punches d, and thus release the same from the head a, as clearly illustrated in Fig. 5. Again, by turning the key I) ninety degrees from the position shown in either Figs. 4 or 5 the end of the key I) when said key is inserted into a channel a may be projected into the path of either of said punches d, as illustrated, for instance, in Fig. 3. In Fig. l of the drawings the varying positions of the keys I) are illustrated. Thus numbering the punches d from 1 to 16 from the left to the right in said figure the first key I) is designed when pressed inward to lock punch number 1 to the head a and to leave punch 2 free. The second key I) is designed to lock punch 4 to the head and to leave punch 3 free. The third key 1) looks punch 5 to the head and leaves punch 6 free. The fourth key locks punch 8 and leaves punch 7 free. The fifth key 1) locks both punch 9 and punch 10 to the head. The sixth key I) locks punch 12 to the head and leaves punch 11 free. The seventh keyb leaves both punch 13 and punch 14 free in the head, and the eighth key 12 leaves punch 15 free in the head and locks punch 16. In the arrangement shown in Fig. 1 when all the keys are pressed inward into the head the punches numbered 1, 4, 5, 8,9, 10, 12, and 16 will perforate the card A, as indicated on the row A of perforations on said card A in Fig. 8. The keys Z) should be so arranged in the head athat they may be readily removable from the channels a and yet may when in position in said channels a be normally retracted from the path of the punches d. To secure this arrangement, upon the body or shank of each key b is coiled a spring h all the springs lodging in the vertical recess or slot ca of the head and hearing at one end against the block a and at the other end against one or more pins 19 inserted in the body or shank of the key I) and readily removable therefrom. To change the adjustment of a key I), all that is necessary is to first withdraw the pin or pins 12 and then draw out the key I) from its channel a In insert-' ing the key I) in its new position the shank is passed through the spring I) and the pins I) inserted to confine the spring between the pins 19 and block a. A second feature of my invention resides in the provision of a back peg-hole punch d controlled by a lever or push-key g, projecting from the back of the head. This punch (Z and its key g is in addition to the front peg-hole punch d and its key g, and the preferred arrangement is illustrated in Fig. The key g traverses the lower block (1 to a point immediately in the rear of the line in which the regular punches at are arranged, and the punch d controlled by said key g, is arranged in a plane parallel to the plane of the regular punches cl, but back of the same. With this additional back peg-hole punch (Z and its controlling key or lever g the back peg-hole A may be punched in the card A when the first row of regular holes is punched in said card and without shifting the card in the head. The front peghole A is punched, as heretofore, bythe front peg-hole key d at the time the last row of regular holes is punched in the card.
Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a card-punching machine, a series of regular punches arranged in pairs, and a single key for each pair of punches, said key adapted to engage either one or both of said punches in the pair, substantially as and for the purposes described.
2. In a card-punching machine, a head, a
series of regular punches depending from said head, and a series of keys arranged in said head, each key arranged to control a pair of adjacent punches so as to lock either one or both of said punches to said head.
3. In a card-punching machine, a head, a series of regular punches arranged in pairs in said head, a key arranged to control a pair of punches, said key having a shank and a rectangular end projecting from said shank and adapted when turned in said head to lock either or both of the punches in said pair to the head.
