IMPROVEMENT IN MACHINES FOR PERFORATING PAPER.

SpecIfication forming part of Letters Patent No. 1 53,025, dated July 14, 1874; application filed May 16, 1874. 1

To all whom it may concern:

Be it known that I, LYMAN A. UPSON, of Enfield, county of Hartford, State of C011- necticut, have invented a new and useful Improvement in Machines for Perforating Paper, of which the following is a specification:

My invention consists of a serial punchingmachine, for perforating duplicate sets of pattern-cards for jacquard or figured weaving, and for perforating figures or designs for other purposes, in which the punches are arranged so that, for making different patterns, some of them may be permitted to rise and not perforate, while others are held so as to perforate, the material to be perforated being moved against the punches.

For readily effeotin g the changes which are necessary in the order of the operative punches for the great variety of patterns required, a perforated sexagon beam, termed a card-cylinder, working the pattern-cards of the pattern to be perforated, is combined with the punching-machine, and is so contrived that the pattern-cards of the pattern to be perforated or duplicated move keys (which act as stops to punches) from over the punches which are not to act, and allow them to rise and allow other keys to remain over those punches which are to act, and retain those in their working position; or the operation may be the reverse of this, moving keys over punches which are to act, and allowing the keys for punches which are not to act to remain stationary, and after each operation there is a plate so combined with the working of the perforated cylinder, and keys which act as stops to the punches, as to return all the keys to their first position for the selection from the whole by the next pattern-card, and thus cause the perforation to be made in accordance with the pattern to be duplicated or perforated, whatever it may be.

By this means any design or pattern can be perforated orpattern-cards for figured weavin g can be repeated, after the first set is made,

very rapidly and much cheaper than they can by the present method of making them.

Figure 1 is a plan view of my improved perforating-machine. Fig. 2 is a sectional elevation taken on the line x-w of Fig. 3. Fig. 3 is a sectional elevation taken 011 line y y of Fig. 1. Fig. 4 is a detail of the mechanism for rotating the card-carrying cylinder. Fig. 5 is a side elevation.

Similar letters of reference indicate corresponding parts.

A represents a gang of punches, comprising as many as will be used for all thediffen ent patterns to be perforated, or patterncards to be duplicated. They are arranged vertically in a substantial beam, B, having suitable holes C bored to receive them from the under side. They are flattened on one side to pass the needles D, and project below the beam, through plates E F and a stripper, G, to a point a little above the die-plate H,

and they have a collar, I, between the plates E and F, to be controlled by them. For each punch there is a key, consisting of the pin or rod J, attached to a wire or needle,D, extending beyond the beam B to the perforated card-cylinder, to hold the punch to its work when it is to perforate; the said keys being so arranged that when the pattern-cards L are operated against the keys by means of the perforated card-cylinder T, worked by the elbow-levers U and cams V on driving-shaft 0, they will move from over the punches that are not to act and remain over those that are.

The operation of the keys may be the reverse of the action here described, as hereinbefore shown.

The object to be perforated is placed on the die plate H and forced against the punches by the eccentrics N on the driving-shaft O, and it is discharged from the punches by the stripper-plate P, which is lifted from its rest Q by the die-plate when the object to be perforated is presented to the punches and it is pulled down again to said rest, when the die-plate goes down, by the shouldered rods R, which pass through the plate and are adjusted for a little vertical play, having a nut, S, adjusted at the lower end, so that just before the dieplate comes to the end of its lower movement it pulls the stripper down by means of the rods and nuts. The plate F is a stationary guide for the punches, and it also prevents them, by means of the collars I, from falling too low; but plate E is a movable plate to pull down the punches in case they may stick, so that the keys can go back over them. This FFIC'E. V

plate is also pulled down by the rods R, which are shouldered above it, inthe same manner as in respect of the stripper-plate. The perforated card-cylinder T, which carries the belt of pattern-cards, is arranged and operated forward and back by the elbow-levers U and cams V, and turned by the pawls W and pins X, and in practice may be much longer than the breadth of the punching; apparatus; so that, when the pattern'eard belt is composed of two or more belts of pattern-cards, placed side by side, and the cards wired together (as they are used in some looms) when wishing to make duplicates, the beltean be put on the card-cylinder entire, and after running one set of cards as long as desired it can be shifted along the cylinder lengthwise to use another set, and thus save the labor of detaching the different sets from each other.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.' The combination, with the jacquard mechanism, of a series of stoppers and punches, substantially as and for the purpose specified.

2. The combination of key-stops and punches, substantially as and for the purpose set forth.
