CHARLIE EDJVIN WEEKS, OF OAKLAND, CALIFORNIA, ASSIGNC'R OE GIVE-THIRD TO ERNEST J. COOK, F OAKLAND, CALIFORNIA, AND ONE-THIRD TO HAGER LEON, OF

SAN FRANCISCO, CALIFGRNIA.

PAPER-ROLL ABUTTER.

To all 107mm it may concern Be it known that T, CHARLIE EDWIN TE-EH8, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Paper-Roll Abutters, of which the following is a specification.

his invention relates to improvements in holders for rolls of paper such as are used for wrapping paper, toilet paper and the like.

The obj ectof the invention is to provide an attachment for paper roll holders for automatically projecting the end of the roll of paper after the desired amount has been torn off to provide for the ready gripping of the paper by one end when another supply is required.

' With this and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure l is an end elevation of a roll holder equipped with this attachment and with the attachment in raised position. Fig. 2 is a similar view with parts broken out and with the attachment in lowered position-which it assumes wien the paper is being unwound from the roll. Fig. 3 is a front elevation thereof. Fig. 4 is a transverse section thereof. Fig. is a detail plan view of one end of the feeding rolls. 6 is a detail view of one of the rollers.

This attachment may be applied to any roll holder and in the embodiment illustrated is shown mounted on a stand comprising a base A. having spaced uprights B and C connected at their upper ends by a cross bar D. A shaft E is revolubly mounted in the uprights B and C and on which a paper web F is wound. This improved attachment as shown comprises a frame composed of two arms 1 and 2 pivotally mounted at one end on studs 3 which project from the outer face of the uprights B and G, preferably below the shaft E. The other ends of these arms 1 and 9 are connected by a paper feeding and severing device in the form of upper jaws a and lower jaws 5 hingedly connected at one end as shown in Fig. 8 to provide for the placing of the paper web as is Specification of Letters Patent.

shown clearly in Fig. 2. These jaws have longitudinally extending upper and lower cutting blades 4t and 5 for severing the paper web at this point, the upper blade being shown hollow ground and the lower ground at right angles.

Two rollers 6 and 7 are revolubly mounted in suitable hearings, in the aws t and 5 and are designed for feeding the paper web F between them. These rollers are arranged in close proximity to each other as shown in Fig. :2, being spaced apart sufiiciently to permit the paper web F to pass between them and be fed thereby on a forward pull being exerted on said web. A spring catch 12 re liably connects the jaws 4t and 5 at their free ends to hold the rollers in operative position. The upper jaws 4t have transverse slots 13 therein in which the spindle ends of the upper roller 6 are mounted to adapt said roller to move laterally relative to the roller 7 to provide for variation in thickness of the paper used. Plate springs 14 are m0unted to bear on said spindle ends to hold the roller 6 in yieldable engagement with the roller 7.

The upper roller 6 has a peripheral recess 8 formed in one end thereof and extending around the entire circumference to receive a flexible element 9 which is adapted to be wound on said roller. This element 9 is here shown in the form of a cord secured at one end. to the cross bar D of the holder and at its other end in the recess 8 of the roller 6. In the other end of the roller 6 is mounted a spring ccmrolled shaft 10 which projects beyond the end of the roller and forms a journal for this end of the roller. A coiled spring 11 encircles said shaft 10 and is secured atone end to said shaft and at its other end to the roller as is shown clearly in Fig. 6. The turning of the roller 6 in one direction will wind up the spring 11 and unwind the cord 9 from the roller which occurs when a pulling tension is exerted on the paper web F and when said web is released or torn ofi' the spring will uncoil and thereby feed the web forward a short distance and at the same time will wind up the cord 9 on the roller 6 and raise the attachment into the position shown in Fig. 1 leaving the end of the web projecting a suiiicient distance to be readily gripped when a further supply of paper is desired.

lVhile l have described my invention with more or less minutencss as regards details and as being embodied in certain precise forms, I do not desire to be limited there-to unduly any more than is pointed out in the claims. On the contrary, I contemplate all proper changes in form, construction and arrangement, the omission of immaterial elements and substitution of equivalents as circumstances may suggest or render e2;- pedient.

1 claim as my invention:

1. The combination of a. pivoted turnable roll holder, arms pivoted out of line with the roll holder axis, feed rolls upon the outer ends of said. arms, one of said rolls containing a torsional. spring, a cord coiled around said feed roll and having its other end fixed, said cord winding upon the feed roll and advancing the paper when the feed roll holder is raised about its pivots.

2. The combination with a paper roll holder and its journal. support, of arms journaled out of the axial line of the holder, feed rolls and cutters mounted upon the outer end of the arms and between which the paper is at vanced, a cord fixed at one end and having the opposite end coiled around one of the feed rolls, a torsional spring within said roll adapted to wind the cord and advance the paper as the arms are moved up and dow about their pivot.

3. The combination with a paper roll support, of a frame pivotally mounted on said support, feed rollers mounted in said frame, a cutter disposed in advance of said rollers, a flexible element connected at one end to one of said rollers and at its other end to said roll support, and a spring carried by said roller for winding up said flexible element when the roller is turned in one direction.

a. it feeding attachment for paper roll holders comprising a frame having revolubl mounted rollers arranged therein and disposed adjacent to each other, a cutter arranged in advance of said rollers one of said rollers luring a recess in one end, a shaft rcvolubly mounted in said recess and projecting beyond said roller to form a journal for one end thereof, and a coiled spring wound on said shaft and connected at one end thereto and at its other end to said roller.

A feeding attachment for paper roll holders comprising a frame having revolubly mounted rollers arranged therein and disposed adjacent to each other, severing means arranged in advance of said rollers one of said rollers having a. recess in one end, a shaft revolubl mounted in said recess and projecting beyond said roller to form a journal for one end thereof, and a coiled spring wound on said shaft and connected at one end thereto and at its other end to said roller, the other end of said roller having an annular recess therein, and a flexible element secured at one end to said recessed endv of said. roller and adapted to be connected at its other end to a. lixee support.
