Specification of Letters Patent.

Patented Feb. 5,1907.

Application filed April 27,1906. Serial No. 314.031.

To all whom it may concern.-

tion.

My present invention relates to roll-paper: holders and cutters; and it particularly relates to the constructions, arrangements,

and combinations of the various parts, as:

well as the apparatus as a whole, all of which will hereinafter be more fully described, as.

well as clearly specified in the appended claims.

In the drawings illustrating the best: form of apparatus to me now known for em-' bodying my inventlon, Figure 1 1s a sectional side elevation view substantially on line a: at of Fig. 2. Fig. 2 is a front elevatlon view thereof and showing a portion of a simi lar cutter bolted thereto, the foot of which 1s. Fig. 3 in its up in central vertical section. per part is a side elevation v1ew of one of the superfeet and the lower part thereof 1s a plan view thereof. Fig. 4 1n its upper part 18 a: side elevation view of one of the subfeet and the lower part thereof is a plan view thereof? Fig. 5 is an enlarged plan view of the bearing-cup, showing the frame-rod 1n cross-section. Fig. 6 is a sectional end view of a SllCling knife and showing a P01131011 of the frame-rod upon which it slides, and Flg. 7 is an enlarged plan view of sa1d SlldlIlg. knife.

In said drawings, 10 is a preferably square rod bent substantially U-shaped, with two of its diagonally opposite corners in the samevertical plane. This rod forms the frame of the device, and the lower ends of sa1d frame are provided with preferably square shoulders 11, Figs. 1 and 2, each passing through similarly-shaped opemng 12 in the top of the superfeet 13, and said shoulders 11 are riveted or otherwise secured to sa1d feet 13. To each of the vertical members of said frame are secured bearing-cupsv 14, having a substantially \I-shaped slot passlng vertically through their outer ends, sa1d cups being secured to said frame, preferably by clamping or pinching the walls Of'Sflld slot against said frame, said cups bemg'formed of malleable iron or brass to facilitate said clamping or pinching. The bottom face of each of said feet 13 is provided with a V- shaped recess 18 for the purpose of fitting the-horizontal top portion of the frame-rod 10 in building cutter upon the top of another, in which case another foot 13, unattached to rod 10, is secured to the bottom of the foot 13, attached to the top cutter, said feet 13 clamping the horizontal portion of frame-rod 10 between their registering recesses 18, said feet 13 being thus secured together by bolts passing through openings 19 in the opposite ends of said feet 13.

Tlhe fleet 13 fare, as abogre described, specia y a a te or yrami in ur oses, and if they wei e of suilibient leng h to Enable the machine to stand upon them they would proj ect an unsightly distance'from the machine and interfere with the knife when feet of such length would be employed for pyramiding purposes. To this end the feet 13 are formed relatively short, and when used for sup porting the machine upon the counter a subfoot 20 of greater length is employed intermediate said feet 13 and said counter, said feet 13 and 20 being secured together by bolts 21, Fig. 1, passing through said openings 22, Fig. 4, in feet 20. A lug 23 projects from each of the feet 20 and fits the recesses 18 in feet 13 inorder to register said openings 19 and 22 in said feet. Said projection 23 does not fill said recesses 18, and enables a bolt 25 orother suitable fastening device, Figs. 1 and 2, to be passed. through said recesses 18 in said fixtures when setting end to end, and thus secure themtogether in such position, which position is termed a fiat pyramid.

Hooked over or otherwise fulcrumed upon the horizontal portion of frame-rod 10 are two arms 30, onenear each side of the frame. The lower ends of each ofsaid arms are rigidly connected together by rods 31 and 32, separated from each other, the former being adapted to rest upon the paper-roll to retard themovement of the-paper-roll and to prevent the windings of the paper-roll from becoming loose and the rod 32 being adapted to deflect the loose unwinding end of the paper upward and toward the knife-edge by said end of the paper being passed between said rods. At a point above said rods is fulcrumed the knife 33 upon fulcrum-points 34,

said knife being preferably an angle-bar of thin material and said fulcrumins 4 being at the apex of said angle forms by said bar. One side of said angle-bar 33 terminates at a point in advance of the rod 32, which deflects the paper upward against said edge of said angle-bar 33, which edge is the cuttin edge thereof. The other side of said angle-bar 33 projects over and normally rests upon the rod 31, a rubber or other buffer 56 being interposed between them to prevent noise caused by the contact thereof.

In operation the end 50 of the paper unwound from the paper-roll is directly under the edge of the knife, andwith other forms of apparatus now on the market the paper-roll must be turned by hand to cause said end of the paper 50 to be projected a sufficient distance from under the knife to enable the thumb and fingers to grasp the pa er and draw it from the roll the proper lengt before cutting the same. However, with my present invention all that is necessary is to advance the thumb and forefinger toward the cutting edge of the knife, separated ready to grasp the paper. The thumb contacting with the edge of the knife 33 will rock the knife upon its ivot-pins 34 and to the position shown in otted lines in Fig. 1, in which position the end 50 of the paper will be between the thumb and fin er ready to be grasped and unwound the desirable length from the roll and cut therefrom by shearing contact with the edge of said knife 33. As soonas the thumb is withdrawn from the knife 33 by drawing the paper from the roll or otherwise said knife by gravity assumes its normal position.

In companion applications, Serial Nos. 73,977 and 73,978, for roll-paper holder and cutter, filed August 31, 1901, I have shown, described, and claimed means for building one apparatus u on the top of another,which means specifica ly consists in arranging the recesses and their cooperating projections in parallel pairs near each end of the apparatus.

Having now so fully described my inven tion that others skilled in the art may freely make and use the same when this exclusive grant shall cease to operate, what I claim, and desire to secure by Letters Patent, is-

1. The combination with a frame having means for supporting the roll of paper, a knife-frame adapted to rest upon the periphery of said paper-roll, a knife fulcrumed insaid frame at a point above its cutting edge, and a deflector for deflecting the end of the paper toward the edge of said knife, said knife being out of contact with said paper-roll and adapted to swing upon its fulcrum with its knife-edge movable past the loose end of said paper-roll substantially as specified.

2. The combination of a frame provided with means for supporting the roll of paper, a knife-frame adapted to rest upon the periphery of the paper-roll, a knife fulcrumed in said frame at a point above its edge, said knife being out of contact with said paperroll and adapted to swing upon its fulcrum with its knife-edge movable past the loose end of said paper-roll and means for limiting the pivoted movement of said knife and returning it to initial position substantially as specified.
