Application filed October 3, 1908. Serial No. 456,001. 1
To all whom it may concern: 9 l
Be it known that I, PHILIP L. S'rorm, citizen of the United. States, residing at Elgin, in the county of Kane and, State of lllinols,
have invented certain new and useful Improvements in Electric Paper-Cutters, of which the following is a specification.
The present invention relates topaper cutting mechanism and is designed more particularly to devise a cutting mechanism electrically actuated for cutting a stripror webof paper into lengths or blanks of uniform or predetermined size.
In accordance with this invention, the strip or web of paper or like material to be cut up'into lengths is provided at intervals with ,a circuit closing contact consisting preferably of an electric conducting ink printed or otherwise appliedto' the sheet materialat intervalscorresponding to the length into which the same is to be subdivided. A
cutting mechanism is arranged to sever the strip or web and is electrically actuated,the
operating means beinginclude in an electric circuit which is completed by the circuit closing contacts of the strip or web, thereby the latter into the predetermined severing lengths. I
For a full understanding of the invention, and the merits thereof and also .to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings.
While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is in both views of the drawings by the same] shown in the accompanying drawings, 'in which: l v
Figure 1 is a topplan view, showing the application of the invention; and Fig. 2 is a longitudinal section on the line wm of Fig. 1,.
Corresponding and like parts are referred to in the following description and indicated reference characters. 7
The web, or strip of paper, or other sheet material to be severed' into lengths, is indicated bythe reference numeral 1. Circuit closing'contacts 2 are provided at.intervals in the length of the strip or web corresponding to'the sections or parts into which the same is out. These circuit closingcontacts circuit to electrlc conducting ink whichmay be ap are regularly spaced when the strip or web' plied by any form of printing mechanism I f term electric conducting ink is to be underthe electric actuating means for the cutting mechanism. One a form of ink admirably adapted for the purpose comprises graphite,
powdered metal and sulfate of copper and a'binder. The strip or web may be fed to the cutting mechanism from a'roll or in a single length. The cutting mechanism consists of a fixed blade Sand a movableblade 4, said blades being arranged upon opposite and at the time that the strip or web is printed with the required matter, By the -sto0d any ink or material that is a good sides of a table or support 5 over which the strip or web 1 passes. The movable cutter 4 is attached to one end ofa lever 6, the
opposite end of said lever being provided with a soft iron bar constituting the'armature 7 of an electro-magnet 8 which isincluded in an electric circuit adapted to be closed by means of the contacts 2. The circuit, including the electro-magnet 8 may be closed directly or indirectly; by means of strong current;. is required to energize the electro-magnet 8 sufficiently to'operate the 'movable cutter and in order to prevent the burningof paper or web to becut up into lengths atthe instant of'the closing of the circuit it is preferred to employ a light circuit including the electro-magnet 8. Blades 9 cgnstitute terminals of the light e closed directly by the contacts- I 2 and'to. utilize said circuitfor closing the contacts 2. It has been discovered that a circuit, and are spaced apart and are so.
' placed'as to be electrically connected by the contacts 2, to complete the circuit at the proper time to effect severance of the strip or webrl. The blades 9 consist oflight springs and have adjustable connection with av support 10 thereby-admitting of varying electro-magnet 11 which attracts a lever 12 'the same being provided with an armature.
'105 their position with reference to the contacts '2. The light electric circuit includes an of said electric circuit. When the electromagnet is energized by the closing of the circuit through the contact 2, the lever 12 is attracted and closes the circuit through the -ele ctro-magne t 8, which attracts the armature 7,and moves the cutter 4 to sever the strip or,web. This operation takes place the instant a contact 2 engages with the blades 9, the parts being so arranged that the severance of the strip or web 1 is through the center of the circuit closing contacts 2,
whereby a portion of each contact appears at opposite ends of a blank or section. To prevent the blades 9 tearing light paper, rollers 14 are fitted thereto, and these rollers further insure a positive connection between the contacts 2 and the blades 9.
A roller 15 is located opposite to the extremities of the'blades 9 and supports the strip or web 1 in line with the contact of the blade 9 with said strip. The strip or web is advanced over the table or support 5 bymeans of a pair of feed rollers 16. The strip, or web of paper, or like material provided with addresses, labels, advertising matter, or designs printed thereon at regular intervals and spaced apart so as to leave a margin between the printed matter, is also supplied with thecircuit closing contacts which are likewise printed upon the strip or web preferably at the timeof imprinting the required matter thereon and which may be effected without any appreciable cost. The circuit closing contacts are located midway between the printed matter of the strip or web so as to insure severance of the latter into uniform or equal lengths, whereby proper margin is provided. The strip or web may be rolled and may be subsequently cut at any time. When it is desiredto sever the strip or web,'the same is passed over the table 5, being fed thereover by the rolls 16, and passing between the cutters 3 and 4.
\Vhen a circuit closing contact 2 engages with the circuit terminals or blades 9, the
circuit is closed in the manner stated and I the electro-magnet 8 energized and the arma ture 7 attracted, thereby actuating the cutorder to return the paper to a ter 4 and severing the sheet.
f It is preferred to have'the'support or table 5 arranged in vertical or upright position.- However it may be located horizontally or at an angle. VV-hen the cutter 4 operates, the end of the strip or web is'pushed beyond the edge of the stationary cutt r 3 and in position to pass between the cutters 3 and 4, a stripper 17 is provided and may be of any construction. As shown the stripper 17 consists of an. approximately U-shaped frame which is pivotally mounted upon the shaft of the upper feed. roller 16. Having thus described the invention, what is claimed as new is:
l.' In a machine for cutting strips into predetermined lengths, a support, an energized circuit including cutting mechanism, means for feeding a strip to the cutting mechanism, means carried by the feeding device for pressing the strip against the support at said cutting mechanism, and con tacts arranged adjacent the strip feeding meansand adapted to close the circuit through spaced conductors on said strip I thereby to actuate the cutting mechanism.
2. In a. machine for cutting strips into predetermined lengths, a support, a high potential circuit including a cutting device, means for fe'edinga strip to the cutting device, means carried by the feeding device for pressing the strip against the support at said cutting device, and a low potential circuit including spaced contacts arranged to intermittently engage a conducting surface on the strip as the latter is fed to the cutting device thereby to close both circuits and actuate predetermined lengths, a. support, an cnergized circuit including a cutting device, means for feeding a strip to the cutting device, means for pressing the strip against the support at said cutting device, and a second energized circuit including spaced contacts arranged to intermittently engage a I conducting surface on the strip as the latter is fed to the cutting device, thereby to close both circuits and actuate said cuttin device. In testimony whereof I afiix my signature in presence of two witnesses.
