Specification of Letters Patent.

Original application filed November 15, 1913, eerial'lvo. 801,293 I-atent 1Tb. 1,198,492, dated'September 19, 1916. Divided and this application filed. March 2?, 1316. Serial No; 86,097.

To aZZ whom 2'25 may concern.

Be it known that I, EDWARD J. Von Pam, a citizen of the United States, residing at Dayton, in the county of, Montgomery and 1 State of Ohio, have invented certain new and useful Improvements in Oash-Regis ters, of which I declare the following to beber 15, 1913 and a reference may be had to,

said application for a specific embodiment of this invention.

In previous constructions the perforator is usually carried by a rotatable element having an invariable movement and the perforator teeth are so arranged that all are brought into play at the same instant. This causes the machine to run hard at that particular point of the operation. .One object of the present invention is to provide a per forator so arranged that the teeth, while they are carried by an invariably moved rotatable element and perforate in a straight line at right angles to tl e length of the strip of material, are not brought into play simultaneously, but one after the other, thereby distributing the perforating operation over a greater part of theoperation of the machine and making the machine run more easily.

Another object of the invention is to pro vide improved means for holding the paper against or opposing it to the teeth of the perforator. V

In previous constructions a roller of rubber or similar yielding material was used, into which the teeth of the perforator sank after they passed through the paper. Such rollers are necessarily short lived and therefore unsatisfactory, a condition which the applicant remedies by using an improved roller made of steel or other durable material and arranged to accomplish the same result as the rubber roller.

With these and incidental objects in view, the invention consists of certain novel features of construction and combination of parts, the essential elements of which are set forth in appended claims, and a preferred form of embodiment of which is hereinafter described. I

l/Vith reference to the drawings which aocompany and form part of the specificat1on: 4 I

roller 82, carrying the perforator blade 101' and a roller 31 composed of steel or similar material and having annular grooves 127,

Patented oet. as, 1917. I

Fig. 2 is a top view of the perforating de-' corresponding to the teeth in the perforator.

The sh-aftBO, upon which the roller 81 is loosely mounted, has secured thereto a gear 79 and a disk 129. The gear 79 may be connected in any desired way to a part of the machine of which the present invention is made an element. Fastened to the roller 81 is a disk 133 and a gear 1-31. In order to allow the roller 81 to move laterally on its shaft, the roller 81 is driven through studs 135, secured to the gear 131, and projecting into holes in the disk 129'. The perfora'tor roll 82, loosely mounted on the shaft '95, has rigidly secured to it the disk 13 1, and the gear 132. The gear 131 meshes with the gear 132 and the disk 13?: extends into the recess between the disk 134: and the gear 132,-so'th'a't any lateral movement of one roller will be imparted to the other and the teeth of the perforator and the grooves of the roller 81 will always be held in 'alinement. Both the roller 82 and the roller 81 are set at air-angle to the length of'the strip of material 83 to be perforated, as shownjin Fig; '1, but parallel one to the other with the strip 83 passing between them. The roller 82 is cut away, as shown in Fig. 5-, and the is at right angles to the edges of the strip 83. The line of'the teeth also conforms to the curvature of the r ll 82 and when the rollers are rotated, the teeth the end 138, are first brought into engagement with the paper and the other teeth are carried in successively until the ones at the end 139 have performed their work. By this arrangement of the blade, the teeth are not carried into contact with the strip simultaneously, but at the same time the line of perforation is at right angles to the length of the strip. However, owing to the angular position in the printer of the perforator rollers, the path of rotation of the teeth is not parallel to the length of the strip and the tendency would he, therefore, to pull the strip to one side while the perforator teeth are in engagement with it To olfset this, there is cam into the slot of which there eX- tends an antifriction roller 14:2 carried by a bracket M3 secured to the frame of the device. At the instant that the teeth 138 of the perforator engage the strip the point 14-1, Fig. at, of the cam slot strikes the roller 1%2 and the

rollers

81 and 82 through the connection established by the dislrl33 are both shifted laterally on their shafts until the point i ls of the cam slot passes the roller, at which time the last tooth at the end 139 of the perforator passes out of engagement with the strip. The surface 146 of the cam then shifts the rollers back to their normal position, in which position they remain during the rest of the rotation.

The portion M l to 1&5 of the cam slot is so graduated that during the time the teeth of the perforator are working their line of 1 travel is in a plane parallel to the edges of the strip instead of being as it is normally at right angles to the inclined shaft 95. This overcomes the tendency to pull the strip to one side and causes it to move continuously in the direction of its length, even while the perforator teeth are in engagement with it.

The actuation of the rollers may be intermittent or constant as desired and the strip of material may be moved any desired distance between perforating operations without departing from the present invention.

While the form of mechanism herein shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.
