" 'VIPERFORATING ATTACHMENT.

Application filed. June 6, 1921. Serial No. 475,302.

To all. whom it may concern:

Be it known that LALBERT E. RIPLEY, a citizen ofthe United States of America, and a resident of Bay City, in the county of Bay and State of Michigan,have invented cerf tain new and useful Improvements inPerforating Attachments, of which the following is a specification. y

This invention relates to perforators for perforating paper and the like, and particularly to perforators such as used in printing shops where a large amount of this perforating work is required to be done. I

,One object of the invention is to design a. very simple, durable and economical perforating attachment which can he quickly and easily attached to a printing press, but which is particularly designed to be attached to the commercially named Kelly press.

Anotherobject of the invention is to design an adjustable perforating attachment whichcan be easilyadjusted to suit different weights of papers, and which will form a neat and clean perforation. a

With the above and other objects in view,

the present inventionconsists in the combi-' illustrating tachment in y and is provided with ,companying drawings,

nation and arrangement of parts, hereinafter morefully described, illustrated in the acand particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion and minor details of construction. without departing from the spirit, or sacrificing any of the advantages of the invention. I

In the drawings:

Fig. 1 is a fragmentary view of the rear end of a commercially named Kelly press my improved perforating atplace thereon.

Fig. 2 is a crosssectional view of one of the perforating heads.

Fig. 3 is an enlarged front view of one of the perforators and grooved rollers, and Fig. 4 is a side view thereof.

Referring now particularly to the drawing in which I have shown the preferred embodiment of my invention. The frame of the press I have indicated by the numeral 1, this can be of any suitable construction, standards or uprights 2 rigidly secured to the said frame, a transversely disposed bar 3 being detachably secured to the upper ends thereof. A gear casin i is secured to the side of the press, and 1s adapted to house a train of gears tain parts can be readilydeta'ched,

dle the stock not shown) for driving the transverse shaft 5 which is journaledin the hub 6 rigid on the frame, rearwardly extending arms 7 being formed integral with this hub, and a similar transverse shaft 8 is revolubly journaled in the free ends of these arms.

A series of rollers 9 are securely mounted on this transverse shaft 5 in spaced relarear of the machine over these rollers 9, and

is engaged by the belts 12 which carry it throughas clearly shown in Fig. 1 of the drawing, the stock being indicated by the numeral 14 and is printed before .it is engaged by the belts 12. a

Incertain instances it is necessary that this stock be perforated in order that oerfor instance the well known check which is usually attached to a-stub; as these checks are used they are of course detached from the stubs, the perforation insuring that the stock will easily tear and part on'a straight line. Iamaware that there are a number of perforating devices in use at the present time, but these are mostly very expensive, being built as an individual machine, requiring the services of an operator, to hanand feed it through the perforating machine. My improved attachment eliminates the service of the operator and saves the time required for feeding it through the machine, as the stock is automatically perforated as it travels through the press, and in no way interferes wit-h the printing.

The bar 3 is secured to the uprights 2 by means of the bolts 15, an elongated slot 16 being formed therein, and a head 17 embraces the said bar tends through this head, the upper end being threaded to receive a nut 19 in the usual manner, and a shoulder 20 is formed intermediate the length of this bolt, the lower end being bent at a right angle and on which is revolubly journaled the perforating wheel as shown; a bolt 18 ex 21; this wheel has a comparatively wide face, and is formed with a plurality of relatively small perforating teeth 22 integral therewith which are adapted to pierce the stock feeding beneath it. A coiled spring 23 is interposed between the shoulder and the bottom of the head, and it will be obviou-s that by manipulating the nut 19 any desired adjustment can be secured to suit the different weights of stock.

The head is secured to the bar 3 by means of a stud bolt Ql extending through the slot and threaded into a similarly threaded opening in the head, and lateral adjustment of the perforators can be easily made by loosening this stud.

The perforating teeth 22 travels on the groove 10, but do not engage the sides or bottom thereof, and it will be apparent that these teeth will not be easily dulled, further, the wide face of this perforating wheel prevents the stock from crinkling and clinging to the perforating teeth, obviating the necessity of a stripper.

To prevent the bolt 18 from turning in the head a dowel 25 is secured thereto, the free end extending through a slotted opening 17 formed in the head.

Considerable care is required in the adjusting of these perforating rollers to suit the stock, and to insure this adjustment being maintained when secured, I provide a small spring member 26 which I secure to the back of the head by means of a screw 27; this spring extends upwardly and bears against the nut 19 to prevent its turning, or slots may be cut in the nut to receive the said spring if desired.

In the present instance I have shown the perforating teeth integral with the wheel, but it will be readily understood that the teeth can be formed on a relatively thin disk and a roller with a face of suitable width can be secured on either side thereof, and this construction is within the spirit of my invention.

From the foregoing description it will be obvious that I have perfected a simple, and efficient perforating attachment for presses, which will make a very neat and clean perforation and which can be quickly attached to a printing press.

What I claim is 1.- The combination with a printing press having a pair of spaced apart brackets mounted thereon, a longitudinally slotted bar connecting said brackets and detachably secured thereto, a plurality of heads slidably and adj ustably mounted thereon, perforating means carried thereby and comprising relatively wide rollers having a plurality of small teeth formed thereon grooved, driven rollers beneath said perforating rollers and adapted to impart motion thereto and in which the said perforating teeth travel, and means on the heads for maintaining a pressure on the perforating rollers for positively moving the stock over the grooved rollers.

2. The combination with a printing press having a pair of spaced apart brackets mounted thereon, a longitudinally slotted bar connecting said brackets and detachably secured thereto, a plurality of individual perforating attachments slidably and adjust ably mounted thereon and comprising wheels having a plurality of perforating teeth formed therein, driven rollers beneath the perforating rollers, and adapted to impart motion to said wheels, grooves formed therein and adapted to receive the teeth of the perforating rollers, means for exerting a pressure on the perforating rollers, and a plurality of means for continuously feeding and moving the stock to be perforated between the said rollers.

In testimony whereof I affix my signature.

ALBERT E. RIPLEY.
