Patented Dec. 18, 1917.
Application led November 1, 1913. Serial No. 798,638.
"simple severing blade structure which may be quickly attached to or removed from the machine, and adapted for use with standard machines with only slight alterations ir the latter.
The device is shown on an Underwood typewriting machine, and may comprise a tearing blade located above the platen and adjustably supported on the usual brackets which carry ythe paper guide fingers at the.
front of the platen. The blade may have a sliding connection at one end with one bracket, permitting either paper guide to be adjusted longitudmally of the platen, and at its other end the blade may be suitably clamped, as by means of a thumb screw to the other bracket, permitting the blade to be secured in positionvor released for removal from the machine by simply operating'the `thumb screw.
Other features and advantages will hereinafter appear.
In the accompanying drawings, Figure 1 is a perspective view of the invention.
Fig. 2 is a fragmentaryview showing the left-hand end of the blade and the corresponding bracket for the paper guide finger,
the parts being shown disassembled.
Fig. 3 is a similar view of the right-hand end of the blade and right-hand bracket.
Fig. 4 is a fragmentary sectional elevation view of the blade and supporting means;
Fig. 5 is a front elevation view showing the blade in full lines and the associated parts in broken' lines.
The usual rotary platen 1 may be journaled in a platen frame comprising ends 2 and 3 in which is also mounted a rod 4 eX- tending longitudinally over the platen. On
said rod are mounted the right-hand and to which are connected, as by means of screws 7, paper' guide fingers 8 extending downwardly and forwardly'over the front face of the platen to guide the work-sheets or webs a over the printing zone and from thence toward the rear of the machine. The guide fingers 8 carry the usual feed rolls 9.
The paper-severing means may be of suitable `,character and are here shown as. conslsting of 'a blade or cutter 10 located over the platen and extending longitudinally thereof, the edge 11 of said blade in the present example consisting of serrations or teeth. One end of the cutter l0, as shown, the left-hand end, is bifurcated to' form guide arms 12 which straddle the bracket 6,
said arms being supported and guided in recesses or notches 13 formed in the bracket, whereby the blade and said bracket are relatively adjustable longitudinally of the platen, and the blade held against movement in other directions relative to its supporting bracket. The right-hand end of the blade 10 may beformed with a head or thickened portion 14 having a screwthreaded opening l5 to receive a thumb screw 16 which extends. through an opening 17 in the bracket 5, whereby the right-hand end of the cutter 10 may be clamped to said bracket, the head 14 also forming an offset to 4provide space between the blade and bracket l5 for the upper end of the guide'S` and the nut or washer 7 into which the ends of the screws 7 are threaded. lVhen thus clamped, the paper knife is securely held in position, and at the same time permits either one or both of the paper' guide fingers 8 to be adjusted lon itudinally vof the platen to accommodate wes or work-sheets of different widths. That is, the left-hand bracket 6 and the guide finger 8 thereon are adjustable along the platen owing to the sliding connection with the arms 12, suchy the thumb' the bracket 6. The slight tilting movement of the blade in thus removing it is permitted either by a slight amount of play between the arms l2 and the bases oi the notches 13, or by the resiliency of the arms 12. rl`his slight play or loose connection between the bracket 6 and the blade, also serves to permit-a limited movement of each guide linger 8 and its feed roll 9, toward and from the platen independently of the other guide finger, whereby each guide finger and roll maintain their operative position and normal pressure against the work, regardless of variations in the thickness of the work-pieces, or irregularities in the platen.
lt will be seen that the blade may be quickly attached to or removed from the machine, requiring only the manipulation of the single thumb screw or holding device, and when in position does not interfere with the adjustment of the paper guide fingers. The upper portion of the blade is preferably inclined rearwardly in the general direction of the leading end of the web or work-sheet a, so that the latter is bent but little out of its course when brought to the severing edge, and the blade is presented at a suitable angle to the paper when a section is being torn oli".
The guide lingers 8, with theirl brackets, are preferably movable in the usual way about the rod 4: to permit said fingers to be lifted from the platen.
Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.`
Having thus described my invention, ll claim: Y
1. l'n a typewriting machine, the combination with a platen and `aper guides associated therewith, said guides adjustable relatively thereto and relatively to eachother, of a paper-severing device secured to one of said (guides and loosely supported and guide by the other guide, whereby both guides are normally movablefor adjustment relatively to the platen and relatively to cach ot er. f.
2. 1n a typewriting machine having a revoluble platen, the combination with a pa ersevering blade movable lon itudinall w1thin the limits oit' the platenength, o paper guides, and individually movable brackets carrying said guides and having respectively naaaaea a :fixed and a sliding connection with opposaid platen, each guide being free for such adjustment independently of the other, said sliding connection formed to permit the blade to be separated from the guide by a relative movement of the guide and blade lengthwise of the platen.
3. In a typewriting machine having a rev-v oluble platen, the combination with a paper-severing blade shorter than the platen and movable -longitudinally within the limits of the laten length, of paper guides, brackets a justable longitudinally of the platen and carrying said guides, and a clamp connecting one bracket to one end of said blade, the other end of the blade slidably mounted on the other bracket whereby said, blade and guides are adjustable longitudinally of said platen, one of said brackets, with a guide and blade carried thereby, being adjustable relatively to the other bracket and guide,to vary the width ofthe space between said guides, said clamp releasable to disconnect one end of the blade, the other end being then free to slide out of engagement with its bracket for removing the blade from the machine. A v
4. ln a typewriting machine, the combination with a roller'platen, of paper guides mounted to swing toward and from the platen `into and out Vof position to hold the work-pieces against the platen, said guides independently adjustable lengthwise of the platen, a paper-severing blade, and a clamp to releasably connect one end of the blade i with one paper guide, the other end of the blade being provided with an open-ended slot whereby the blade has a sliding connection with the other paper guide, permitting relative adjustment of the latter and the blade lengthwise of the platen, and holdingF the blade against displacement in a direction transversely to the platen, said connection also permitting the blade .to be removed from the machine by releasing said 'clamp andA slidin v the blade lengthwise of the platen to lree the slotted end of the blade from the paper guide.
