FRED TALOOTT, OF PROVIDENCE, RHODE ISLAND.
KNIFE FOR SHEARING PAPER, 80C.
SPECIFICATION forming part of Letters Patent No. 467,316, dated January 19, 1892.
Application iiled March 30, 1891.
To a/ZZ whom it may concern:
Be it known that I, FRED TALOOTT, acitizen of the United States, residing at Providence, inthe county of Providence and ,State of Rhode Island, have invented certain new and useful Improvements in Mounting Knives for Shearing Paper, dto.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
My invention relates to an improved manner of mounting and operating knives-such, for example, as are employed in cutting o pieces from the end of an intermittingly-fed web of paper.
The particular class of machines to which my improvement is especially adapted is printing-presses in which a web of paper is cut transversely into pieces to form labels, Jac., simultaneously with the feeding and printing operations.
In the manufacture of labels from webs of paper it is occasionally necessary to cut them to a rhomboidal or diamond shape, although lthe usual form is square or rectangular. There are certain presses especially adapted to the production of labels, or label-machines as they are sometimes called. An example of a machine of this type is shown and described in United States Patent No. 262,556, granted to Thomas A. Briggs, as` signor, August 15, 1882. In this machine the free end portionl of the webof paper is, as fast asprinted upon, intermittingly fed along between revolving shears or cutters, which act to simultaneously. trim the two longitudinal edges of the web and at the same time cut it into two or more strips, the latter being immediately thereafter cut transversely into suitable lengths, as. determined by the feeding device. v
The object I have in view is to provide machines of the class above referred to with means whereby the cutting-off knives may be used not only to sever the paper at right angles to form square or rectangular-shaped labels, but the same knives may be also readily ad- Serial No. 887,008. (No model.)
justed or set so as to simultaneously sever the strips of paper at any desired angle within the limits of adjustment, thereby forming diamond-shaped labels.
To that end my :invention consists, essentially, in the combination, with a self feeding and printing machine, of two knives mounted and arranged to sever the web of paper at any desired angle to the line of feed.
It further consists in the novel manner of connecting the upper knife-carrying frame, thereby adapting it to be moved axially, independently of the mechanism employed for actuating the knife, all as will be more fully hereinafter set forth and claimed.
In the appended sheet of drawings, Figure 1 is a partial side view of a printing-machine embodying my improvements. Fig. 2 is a similar view, in partial section, as viewed from the opposite side, showing the construction and arrangement of the printing mechanism or press. horizontal section, showing the knife-carrying frames, 85e., taken on line :r x of Fig. 4. Fig. 4:' is a vertical sectional View taken on line o o of Fig. 3. taken through the lower knife-frame, showing a manner of adjusting the latter longitudinally of the machine and also showing the knives arranged at an angle to the plane of the paper. parts shown by Fig. 5. Fig. 7 shows a piece of the web of paper having the end cut 0E square, corresponding to the position of the cutting-off knives represented in Figs. 3 and 4; and Fig. S is a similar view of the paper, the end being cut at an angle. (See Figs. 5 and 6 for a corresponding position of the knives.)
In the drawings I have represented a portion of a label-machine, substantially as shown and described in the Briggs patent, No. 262,556, before referred to. The bed or base h of the machine is supported, say, by legs c.
Fig. 5 is a similar sectional view,
Fig. 3 is a plan view, in partial Fig-6 is a plan view of the To the top of the-bed is secured one ormore heads or frames d of the printing-machine.
A main shaft spasses transversely through the head a, on which is mounted an eccentric e4, arranged to vibrate the chase-carrying bed p to produce an impression upon the traveling web of paper 1o, resting upon the movable IOO bedp, suitably operating ink-rollers p2 rst being passed over the face of the ink-distributing table p3.
To the rear end portion of the machine are arranged a pair of intermittingly-revolving cutter-carrying feed-rolls adapted to simultaneously trim the edges of the web of paper and divide it longitudinally into two or more strips e', Figs. 7 and 8, the number of such strips corresponding to the series of cutters e employed. In dividing the web into three parts or strips e four pairs of cutters are required, the outer ones being used as trimmers, the others at the same time slitting the web longitudinally. These combined feedrolls and cutters are geared together to revolve in opposite directions, and may be actuated by a suitably-operated rack f, intergearing with the gear of the lower cuttershaft.
The rear end of the machine is extended beyond the feeding and slitting` device just referred to to form brackets l1', on which a plate or base h is mounted, the same being provided with a bolt h2 and movable cross-tie h for clamping the parts together in any desired position or relation to the feed-rolls. The holdingdown bolt h2 is secured centrally to the under side of the base m of the normally-stationary cutter-carrying frame m and extends through the plate h. The latter is further provided with a curved slot t', through which a pin or bolt t', secured to the said base m', is passed and secured. From this it will be seen that upon loosening the nut of the bolt c' the frame m maybe swung around axially to any desired position, limited only by the length of the slotted arc i.
The frame m is provided witha fixed or lower knife r', extending transversely of the machine, the construction and arrangement of theknifebeingsubstantiallyas common. The two sides or ends of the frame contiguous to the ends of this knife are extended vertically and are grooved to form guides o, Figs. l and 3, into which the upper knife holder or frame o?. is fitted to reciprocate in a vertical direction. This upper knife fr. is adjustably secured to the lower portion of the holder by screws or in any other well-known manner. l prefer to set or adjust the two knives so as to produce a shearing effect, as common to knives of this class and as indicated in Fig. l. The center portion of the holder n .is enlarged and provided, say, with a removable cap t2. The adjacent faces of the parts just referred to are recessed to receive the ball-shaped end t of the adjustable connection t, thereby forniing a universal or ball-and-socket joint. I would siate that l preferably place the axes of the said partst andh2 in line with each other, thereby forming a common center.
A manner of reciprocating the upper cutter is as follows: Contiguous to the printing-head c is secured upon the shaft s a suitable cam 7c, Figs. l and 3, arranged in revolving to reciprocate a rod or connection w3, jointed at its lower end to an arm or lever w', secured to the front end of a horizontal shaft w, mounted at the rear side of the machine. The shaft extends through ears formed on the back of an upright arm h4, secured to the base h, carrying the cutter-frames m and n. A shorter lever rc2, located between said ears, is adj ustably secured by a screw 0 to the shaft w. To the free end of the lever L02 is jointed a vertical connection u2, the latter in turn being jointed to the rear end of a beam u, fulcrumed at u to the upper portion of the upright h4, the opposite end of the beam being jointed to the connection t-before described. From the foregoing it is evident that a revolution of the crank 7c causes the knife r to make a double reciprocation, as in shearing off or severing the paper lying between it and the stationary knife. Now in order to cut the web 0f paper p into pieces or labels, square or rectangular in shape-say as shown in Fig. 7-the set-screw o of the knife-operating arm 'L02 is first loosenedand the base-plate h (also loosened) next moved along nearer to or farther from the cutters e and press a, according to the predetermined length of labels to be produced, after which the screws h2 and oare retightened, the knife-frames m and fn. then being at right angles to the shaft w or transversely of the paper, substantially as shown in Figs. l, 3, and 4:. At the same time the bolt c' is made to firmly clasp the frame m to the base'plate.
ln Figs. 5 and 6 I have representeda screw 83 and hand-wheel .Stl for more accurately effecting an adjustment of the base-plate h in a longitudinal direction, the same being in engagement with a nut S2, mounted in said plate, as clearly shown.
'Vhen the machine is in operation, the paper will be intermittingly fed ahead between the separated knives during each revolution of the main shaft a distance corresponding to the length of the label to be produced, the rolls and cutters e at the same time trimming the paper and dividing it into strips e. As the forward movement of the paper ceases the upper knife a* is quickly forced downwardly by means of the revolving cam 7c and the several connections, resulting in severing thc paper transversely, as indicated by the line 2, Fig. 7. f
Now assuming that it is desired to produce diamond-shaped labels, Fig. 8, and further assuming that the several adjustments before described are to remain substantially unchanged, the knives may be quickly swung around axially to the desired angle (see Figs. 5 and 6) by simply loosening,` the bolt t', the latter being subsequently retightened. Upon starting the machine the thus-adj usted knives then operate and cut the paper angularly (see line 3, Fig. 8) with the same facility and accuracy as in the former case, or in cutting square-shaped labels. It will be seen that the axes of the bolt h2 and central connection t are substantially in line vertically. Therefore the beam 'a and its connections remain un- IOO IIO
changed and work equally well irrespective of the axial position or relation of the two knives thereto.
By means of my invention only one set of knives is required to cut the labels transversely, the angle of suchl cut being ninety degrees or less, as desired. Moreover, the corresponding angular adjustment may be made quickly and accurately.
It is obvious that, without departing from the spirit of my invention, I may employ the device in machines unprovided with printing mechanism-that is to say, my improvementV can be used to transversely sever unprinted webs of paper or other flexible material intermittingly fed to the knives.
I claim as my inventionl. In a self-feeding and printing machine employing aweb of paper and having cutters for first simultaneously trimming and slitting the web longitudinally, the combination therewith of intermittingly-operating cutting or shearing knives mounted in frames susceptible of axial adjustment, whereby said knives and frames may be set so as to sever the paper at right angles and also at any other desired angle transversely to the plane of the traveling paper, substantially as hereinbefore described.
2. InA a machine for intermittingly feeding and transversely cutting a roll of paper, an adjustably-mounted centrally-pivoted head portion carrying the lower knife, an upperV knife mounted in a frame arranged to reciprocate in said head, and an inrermittinglyoperating lever or connection jointed to the center of the upper knife-frame, constructed and arranged whereby said knifel frames or holders maybe adjusted at any desired angle,`
substantially as described, and for the purpose set forth.
3. In a machine for intermittingly feeding and cutting rolls or webs of paper, an adjustably-secured and centrally-pivoted head m, provided with the lower knife r and vertical guides, a frame n, fitted to reciprocate in said guides, carrying the upper knife, and an intermittingly operating lever or connection jointed centrally to the frame n and in line with the center or pivot of the head m, the knife holders or frames being adapted and arranged to be swung on said pivots to any desired angle, thereby adapting the knives to cut the paper transversely at a corresponding angle, substantially as described.
4. In a machine for intermittingly feeding and cutting webs of paper, the combination of an adjustably-secured lower frame pivoted at its center, a cutter secured thereto, an upper frame or holder mounted to move vertically in said lower frame, a cutter secured to the holder, a connection jointed centrally to the holder, and means for reciprocating the latter up and down, substantially as hereininbefore described, and for the purpose set forth.
5. The combination of a lower knife-carrying frame pivotally mounted and secured in any desired axial position, an upper knifecarrying'frame, and an operating connection jointed to and arranged to reciprocate said upper knife-frame, the axesof the lower framepivot and the said connection being substantially in line with each other.
6. In a printing-machine employing a web or roll of paper, the combination, with intermittingly-operating feeding and printing mechanisms and rotary shears or cutters for trimming and slitting the paper longitudinally, of a pivotally-mounted adjustable lower frame or holder carrying a knife, an upper frame or holder carryingaknife guided by and adapted to move vertically in saidlower frame, and an intermittingly-operating lever or connection jointed to the upper holder, the vertical axes of the connection and the lower frame-pivot being in line with each other, for the purpose hereinbefore set forth.
In testimony whereof I have affixed my signature in presence of two witnesses.
