AARON H. HANDY, OF KANSAS CITY, MISSOURI;

AUTOMATIC PAPER-CUTTING- MECHANISM.

Specification of Letters 1atent.

Patented Dec. 19,1916.

Application filed March 6, 1916. Serial No. 82,369. I

To all whom it may concern: Be it known that I, AARON H. HANDY,

a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Automatic Paper-Cutting Mechanism, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same. i

The invention relates to mechanism for containing rolls of wrapping paper and cutting various lengths from the roll as required.

It is essential that the roll of paper be journaled in suitable frames so that it will roll freely without tearing the paper, and that a suitable brake be provided to check the rolling of the roll when the desired length of paper has been drawn therefrom so that the roll will stop and not unwind more paper than is drawn from the roll. A construction that will admit of employing sheet metal for the cutting knife, and provide for the mounting of a plurality of rolls in one frame is also very desirable.

The present invention seeks to provide an improved mechanism, for supporting rolls of paper and automatically cutting desired lengths of paper therefrom, the features of the invention relating more particularly to certain improvements in the mechanism of the machine embodied in United States Patent No. 1,159,837, which was issued to the applicant Nov. 9th, 1915.

A futher object of the invention is to provide a suitable adjustable resilient brace that will act direct upon the surface of th roll of paper.

A still further object of the invention is to provide for the mounting .of plural rolls of paper and serving them byxa single knife constructed of thin sheet metal and to employ an intermediate rest and stop for the lmife so that it will not spring and tear the paper.

A still further object of the invention is to provide an improved form of brake upon the small roll near the knife so that the paper when drawn from the mechanism rapidly will immediately stop when the drawing tension ceases and no more paper will be drawn than is desired. j i

With these and other objects in View the invention consists in the features of construction, shapes, combinations and arrange ments of parts hereinafter set forth, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings: Figure 1, is a view of the improved mechanism in elevation, arranged for and containing plural rolls of paper. Fig. 2, is a sectional view of the mechanism takenon line aa of Fig. 1. Fig. 3, is a fragmentary enlarged sectional View taken on line 12-42 of Fig. 1. Fig. 4 is a fragmentary enlarged sectional view taken on line c0 of Fig. 1. Fig. 5, is a fragmentary enlarged view. Fig. 6, is a fragmentary enlarged view. Fig. 7 is a view of the mechanism in elevation, arranged for and containing a single roll of paper.

The base 1 is preferably of rectangular shape. as shown and of wood because of inexpensiveness, the end frames 2 and 3 and the intermediate frame 4 being secured to the base by screws 5 and extending upward therefrom, the journal boxes 6 being preferably integralwith the respective frames and open upward so that the rolls of paper 7 may be placed with the journals 8 resting in r the boxes as shown and removed therefrom without manipulating any part of the mechanism.

Secured to the base 1 and opening upward and provided with the flanges 9 along the upper edge thereof is the channel shaped guide 10, the flanges extending toward each other and then projecting downward in the form of teeth 12, forming a trackway be tween the toothed flanges and the bottom 13 of the guide for the spring 14. vThe spring 14 has a wide portion 15 which rests upon the bottom 13 at the end 16 thereof, and upwardly inclined integral pawls 17. which engage the teeth 12, the spring being free to slide along the channel shaped guide 10 when the end 18 thereof is pressed downward and the pawls released from the teeth, the tensionof the' spring produced by the end 19 pend on the swiftness with which the paper is withdrawn from the roll, and that when gagement ,with,the tjeeth 12 and thespring:

will remain in this position untilreadjusted, the shape of the spring producing m'oie brake tension when the roll is of full: size than when the paper is'morene arly removed, this being desirable asthe more paper the more weight and the greater the inertia that must he checked and stopped. U I The ro fjp p ri is WQ d l i t n ne-2. h nspro dea h"p j jou ial'si 8 to fit and revolve freely in the i rii vbb ffia. a .s a.

The curved sheet metal guide 29 separate'd from the flat sheet metal guide only 7 by the sheet of' pap 'er 11 and is'cprovided with thes1et 20.; hrough which the pa er is threaded, the side of the guide 29 being 'Q HrYd it 5 t V6 he 6 6 2 2161112 e de are bfl e h e fi g and ream, a bral te' as hereinafter will appear. v The arm '36 is secured to the flat sheet metal guide 35"i11tei 'mediate,the arms 30 ana;, i pivoted inthe bifurcated jaw 37 at 385 se that the end 39 thereof will bear in e vje t eQi he -th r s an 36 ir in the extreme upward pesit'ioh as w ll o iip' il oin thQd 'S' -I' of the p iatien, hereinafteif, the jaw" 37' Being s'ecu"red to the frame tie piece l byae integral belt 2.;t1ie e beamin se fl to l d fiafiies 2 and e by the grammes, The are 3 or. t e-p rpos QS Pii 2 ne theifl'it f? lguide fidthe lattenservihg also o kni br fr e bi n whentheesired ,ie 'gjh has srd ei gnit -le s leng s a in semen-131511 mm long rolls" fo'r' wade paper ward n'witlidiawn aeaitee Iran 7; the arin ber and inconnection with the mounting of two 1 or more .rolls under the same knife, it being desirabl'e'under certain conditions to mount several rollsTunderfthe same knife especially when the paper is of a narrow width. illhe paper 11 is wound upon the roller 21 and placed with the journals 8 in the boxes 6 after which the paper is threaded over the roller 23 and under the curved portion 25 of the curved sheet metal guide 29until the slot therein 20 is reached; the paper passing upward through this" slot and then outward betweenfthe portion of the curved sheet metal guide 29' and the flat sheet metal'guide knife 3 5 the paper in'normal position always" protruding from the guidessufi'iciently to allow of gripping it to withdraw from the roll? the normal position of the guides and sifpporting arms andpaper being illustrated in Fig. 2. e V

' When'it'is" desired to remove a length of paper from the roll the paper 11 is grasped near the guides 29 and and drawn outward until the desired length extends from the g'aid whenafi upward pull on the paper will instantly-throw the parts of the mechanism toi the position illustrated in Fig. 3 the edge 44 o f th'e guide 3'5 serving as a knife and severing the paper. After the severed the-mechanism immediately assumes the position shown in Fig.- 2 and the paper is eiten'ded as; il'lu'strated in this View, it being obvious that the aper; is always in a position to allowj o'f, gripping it by the hand and that but an instantis required to withdraw and sewer any desired length of the paper. Thiraihi 2 and 3 are each offset and extended outward at 17 in order to secure a -greaterdistancebetweenflthe frames and admit or the guides 29 and'35 being extended to agreater width, this fe'atu're serving to allow thepaper to be withdrawn at a considerable' angle from? a right angle from the axis of the roll 7, so that theoperator will notbe reqiiired tonotice whether the paper is. drawn'at alright"angle from therolls; it heing obviousthat the person desiring wrapping paper is usually in a hurry and will drawand cut the paper without looking at or thinking or thepaper cutting mechanism or the-roll'of paper, the mind being occupied by (aheemaaeis; c

The automatic paper cutting mechanism is of chief importanee for the containing rolls of pa er cuttingfind'serving it in the desired length; but may also be advaa tageously employed for the serving of toilet paper and the like.
