HERMAN HOLLERITH, OF WASHINGTON, DISTRICT OF COLUMBIA.
KEYBOARD-UNCH.
SPECIFICATION forming part of Letters Patent No. 487,737, dated December 13, 1892.
Application filed March 10, 1891 To @ZZ whom t may concern.-
Be it known that I, HERMAN I-IOLLERITH, a citizen of the United States, residing at Washington, in the District of O0lumbia, have invented certain new and useful Improvements in Keyboard-Punches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to certain new and useful improvements in keyboard-punches, and is more especially intended for the purpose of punching or perforating the cards or slips of paper used in the Hollerith electric tabulating system. In said system cards or slips of paper are employed which are perforated at given or predetermined points to indicate certain facts, items, or conditions; and it is the object of the present invention to provide a machine whereby said cards or slips of paper may be perforated or punched at the desired points with speed and accuracy.
To this end my invention consists in a suitable frame carrying a card-holder, a punch adapted to engage and punch a card held by said holder, mechanism for operating the punch, a keyboard supported upon the frame, an index-linger movable over the face of the "keyboard, and mechanism controlled. by the index-n ger to cause the punch to engage and punch the card at a point corresponding to the position of the indeX-nger upon the keyboard, all of which will be fully hereinafter described, and afterward definitely pointed out in the claims, due reference being had to the accompanying drawings, wherein- Figure l is a perspective view o f my device. Fig. 2 is alongitudinalvertical section thereof. Fig. 3 is a detail perspective view of the card-holder. Fig. 4 is a detail view of the punch; Fig. 5, a detail View of the cardretaining spring; Fig. 6, a side elevation of a modified form of the machine; Fig. 7, a top plan view thereof, and Fig. S a bottom plan view of the same.
Referring to Figs. 1 to 5, inclusive, A indicates a base or frame of any suitable configuration, in the rear end 0f which is mounteda swivel B, capable of being revolved or rotated.
Passing through said swivel is a shaft C,which Serial No. 384,498. (No model.)
is free to reciprocate back and forth therein and which is connected at its forward end with a frame D. Said frame is preferably formed in one piece and consists of an upper member d and a lower member d', the upper member d having formed therewith a perforated boss d2, within which is fitted a sleeve d3, projecting below the boss and adapt-ed to rest upon the card to be punched and strip the card from the punch as the latteris withdrawn. The lower member d is likewise formed with a perforated boss dlimmediately below the boss d2, within which is fitted a sleeve d5, held in position and adjusted toward or from the sleeve d3 by a perforated screw-threaded plug d6. The forward end of the frame D is provided with a foot D', upon the under` side of which are secured suitable bearings D2, which will slide easily and noiselessly over the frame A.
E indicates a lever, the rearend thereof being bifurcated and pivoted or hinged to the rear end of the frame D, as shown. To said lever E and at a point immediately over the sleeve cl3 are pivoted two links e e, within the lower ends of which is pivoted a punch F. Said punch consists of a rod or cylindrical piece of metal the lower face of which is concave or hollowed out in such manner that its periphery will form a knife-edge. The forward end of the member d of the frame D is formed with two upwardly-projecting lugs dT C17, united at their tops by a pin d8, which embraces the lever E.
To the member d of the frame D is secured a spring dQ, the free end of which bears against the under side of the lever E and maintains itin an elevated position, except when depressed bythe operator, as will more fully hereinafter appear. The extreme forward end of the lever E carries a knob d10 and a downwardly-projecting pin or finger du.
Upon the forward end of the frame Ais secured a keyboard H, having a series of perforations f, adapted to receive the finger or pin du.
At a suitable point upon the frame A is secured a card-holder or frame G. Said frame is rectangular in shape and of a width just sufficient to receive the card to be punched. Upon each side said card-holder is provided for a portion of its length with an inwardly-turned IOO flange g, underneath which the card is inserted, and upon one side is secured a spring g', the free end of which projects through a slot g2 and bears against the edge of the card. The card-holder G is supported upon four posts or pillars g3, to which it is secured by screws, as shown, and lies between the members d and d of the frame D. To one end of said card-holderissecured a spring g4, of the shape shown in Fig. 5, and which is preferably passed around one of the screws screwing in one of the pillars or posts g3 and limited in its movement by a pin g5, the free end of said spring pressing against the end of the card held in the holder G. The other end of the card-holder is provided with two projecting pins g g, by means of which and the springs g and g4 the card is held firmly in its place within the card-holder G.
Any suitable form of spring may be substituted for the spring shown in Fig. 5.
The operation of the machine above described is as follows: A card of the proper size and shape is inserted within the cardholder G, passing between the sleeves d3 d5, and the knob d10 grasped by the operator and the finger d brought into position over the particular perforation in the keyboard F which indicates the item that it is desired to record. The lever E and frame D being secured to the frame A by the shaft C, passing loosely through the rotating sleeve B, it will be apparent that the linger d can readily be brought over any one of the perforations in the keyboard II, and, pressure beingapplied, the lever E is depressed, causing the punch F to decend and perforate the card atapoint corresponding with the position of the perforation in the keyboard, in which the finger du has descended. The perforations in the keyboard are properly indicated by letters or figures indicating the items to be punched in the cards, and every time the finger d is caused to enter one of said peforations the card will be punched at a corresponding point, the planchets or punched portions of the paper dropping down through the perforated sleeve d5 and plug d6.
In Figs. G, 7, and 8 I have shown a modified form of machine operating in substantially the manner before described. Referring to said igures, A indicates a rectangular frame, upon the under side of which are rigidly secured two transverse rods K K. L indicates an X-shaped frame having' four sleeves or collars k, which encircle the rods K K, the frame L sliding upon said rods from side to side. Upon the upper sides of said sleeves or collars 7c k are formed bearings Z Z, within which are rigidly secured rods M and N, the rod M being longer t-han the rod N and extended to the rear of the machine for a suitable distance. O indicates a frame consisting of the members 0 and o', the lower member o beingprovided at its extremity with a transverse arm o2, having at each extremity a sleeve oi collar o3, which cncircles the rods M and N, and
upon which rods the frame O has a free 1ongitudinal movement. For the purpose of insuring the movement of the frame O in a perfectly-right line the member o near its rear extremity is provided with an arm P, having at its extremity a sleeve or collarp, encircling and sliding upon the extended portion of the rod M. The member 0 of the frame O iS formed with two lugs o4 o5, between which is pivoted a lever R, carrying a punch r, said punch being similar in all respects to that before described, and said lever R is secured near its free end to au index-finger r', sliding in bearings r2 upon the extremity of the member o of the frame 0. Upon the extreme end of the lever R is mounted a knob S.
In all other respects the machine just described is constructed like that shown in Figs. l to 5 and its operation the same, excepting thatin the modified form of machinethe frame carrying the punch has a longitudinal Inovement back and forth upon the rods M and N, and the frame L, on which are mounted said rods, has a transverse movement from side to side upon the rods K K, the index-linger and the punch thus having a universal movement in every direction.
I-Iaving thus described my invention, what I claim isl. In a punching-machine of the class described, the combination of a frame having mounted thereon a card-holder and a keyboard, an index-finger arranged to have a universal movement over the keyboard, whereby said finger may be moved to any desired point on said keyboard, a punch adapted to engage and punch a card held bythe card-holder, and mechanism for operating the punch and controlled by the index-linger, substantially as shown and described, whereby when the punch is operated it will perforate the card at a point corresponding to the point indicated by the index-finger on the keyboard.
2. A machine of the class described, consistin g of a frame having mounted thereona cardholder and a keyboard and a lever carrying a punch and an index-finger, the construction being such that the said lever has a universal movementand theindex-fingermaybebrought into any desired position over the keyboard and when depressed will cause the punch to perforate the card at a point corresponding to the point indicated upon the keyboard by the index-linger, substantially as described.
