Patented Feb. 6, 1906.
Application led January 19, 1905. Serial No. 241,848.
To all whom it 17m/ 11 concern,.- y
Be it known. that I, CLARENCE E. STEERE, a citizen of the United States, residing at Maywood, Cook county, Illinois, have invented certain new and useful Imorovements in Duplicating-Machines, of which the inl imving is a specification.
My invention relates to duplicaiwr chines, and has for its object improtl, in the construction and operation. ci: :s machines` ylin the drawings illustrating the invention, Figure 1 is a side elevation of the entire device g Fig. 2, an end elevation of the same; Fig. 3, a cross-sectional elevation; Fig. 4, a detail of the cylinder and stop mechanism; Fig. 5, a detail of the mechanismfor positioning the printing-roller; Fig. 6, a cross-section ofthe device of Fig. 5; Fig. 7, a detail of the feed mechanism, and Fig. 8 an enlarged detail of a portion of the ink-containing gauze.
The device is mounted upon a framework consisting of end brackets or supports A, connected together by means of suitably-disposed cross-rods ya, and upon the brackets are journ al-boxes a', which serve as a mounting for a journal-shaft B, which extendsfrom end to end of the machine and has secured to itat one end a gear-wheel vl5.' (Best shown in Fig. 1 The gear-wheel is located outside of the supporting-brackets, and between the` brackets are a pair of cylinder-wheels or spiders C, loosely mounted on the journalshalt, which wheels or spiders are connected by means of a smooth impervious metallic covering Iin the form of a split cylinder cthat is, one which extends nearly around the periphery of Athe wheels, leaving a longitudinally-extending open space or ga at one side. A rigid connection between tlie wheels or spiders and the shaft is effected through the medium of an arm C', which is rigidly' mounted on the shaft and provided at its outer end with an elongated slot c', through which passes an adjustable set-screw c, which enables the split cylinder as a whole to be adjustable with respect to the shaft. The rims of the wheels or spiders are provided with recesses C2 in line with the gap in the cylindrical covering, and said recesses provide shoulders c, against which abut a series of four bars or plates C, which are held in place by the pressure of a spring c4. Supermposed upon the impervious metallic covering c is a pervious or perforate covering D, preferably of wire-gauze, and the meshes or perforations in `the gauze, when superimposed upon the impervious metallic covering c, serve to form a series of se arate wells or reservoirs for the retention o ink. Outside of the gauze is 'a perforate ink-absorptive co'vern or sheet d, such as cloth, and u on the clot covering is laid a stencil-sheet t; of the usual character. The ends of the several coverings outside of the interior metallic covering are ada ted to be clasped and held between the ongitudinally-extending bars, which may be removed under the tension of the spring c", releasing the several coverings.
Each ofthe end brackets of the frame consists of side arms or braces E and a central upright support E', which latter is provided with a slot e, and between the slots in the two bracketsl 'extends a slidably-mounted rollershaft e', u on which is mounted a feedingroller E2, o rubber or other suitable material. Depending from the roller-shaft, at opposite ends thereof and inside of the brackets, are a air of arms e2, to which are pivoted swingmg or oscillating arms F, rigidly secured to a longitudinally-extending rock-shaftf, pivoted Within journal-mounting'sf at the lower end of. the rear side arms or supl ort-s of the end brackets. Une of the arms has pivoted thereto and upwardly extending Vtherefrom an actuating-arm G, which is slotted at its upper end g and embraces a cam-shaft p1', journaled in a journal-mounting g2 near t e upper end of the rear side bar or su )port of one of the end brackets. The camaft has mounted thereon a cam H, which contacts a roller h, pivoted to the arm G, so that the movement of the cam serves tol depress the arm G, and with it the `arm F, carrvmg down the roller-shaft, and with it the feeding-roller, against the tension of a spring I, which is secured to the roller-shaft at one end and to an adjustable screw-threaded stem/i at the other end, which stem passes through an ear t on the end bracket and is adjustable therein by -means of a thumb-screw 'i2 or in any other similar manner. Forward of the roller-shaft e and below the plane upon which paper is fed through the machine is a longitudinallyextending stop-shaft, suitably journaled and provided at suitable intervals with upwardlyextending sto s or abutments j, and the stopshaft is furtlier provided with depending IOS 3o f one of the end brackets, and said. lever is i opposite ends of the cylinder are a pair of levers L, of bell-crank form, and said evers are connected at their forward ends by a feedin cross-bar l, having thereon aA covering preferably of rubber, and the opposite ends of the levers are connected, by means of springs l2, to the spider to which the lever is pivoted, which arrangement serves to out- Wardl project the rubber-covered feed-bar and a low the same to be repressed against the tension of the springs when brought into contact with the feed-table.
In order to depress the feed-roller when desired, a lever M 1s provided, which is pivoted at one end to an inwardly-projectin stud m and is provided at its opposite en with a flanged thumb-piece m, adapted to be contacted by a fiat spring m2, depending from shaped to span the end of the lower shaft Ica, and its return movement is effected through the medium of a coil-sprin m3, which allows pressure to be exerted to (gie ress the rollershaft against the tension o the sprin s I, which serve to draw back the roller-sha t after pressure is released from the lever M, and the flat s ring m2 serves to hold the ,lever in de resseci) position.
he device is operated by the crank n', and
lthe cylinder turns, with the lower portion movin from the front toward the rear. While the cylinder is turning the o` erator pushes a sheet to be printed in over t e table K until it. strikes the stops 7'. Just before the cylinder reaches the osition shown in Fig. 1 the rubber-covered bar Z strikes the sheet and drags it inward. At the moment when the b ar l strikes the aper or slightly before that time the cam H egins to operate on the roll h, causing a descent of the roll E2 and a backward-tipping movement 'of the stops y'. The backward movement of the stops j :is quite rapid, thus permitting the sheet of paper to be dragged inward over the said sto s and between the printing-cylinder and t e roll E. By the time the forward edge ofthe paper is fairly between these two cylindrical surfaces the bar Z strikes the cross-bar lc, Fig. 7, and rises slightly. Immediately thereafter the arms L strike the flanges k2 of the rear table k and the bar L is raised clear of the paper. By this means the paper vis releasediand itls feeding movangenthis therefore sto pe unti it is en a e yt e rintin c liiider and the roii' gli? p g his last is accom lished by the cam permitting they roll EE to rise. By adjustment this can occur atan part ofthe printing-cylinder; but ordinarily the first contact between the two will occur when the rintingcylinder is in rotary position. (S own in Fig. 4.) From this time Aon the paper is fed by the rolling action of the cylinder and the roll E, and the roll pressing the aper against the stencil d', with its ink-hol ing backing, causes the desired printing. Therise of the roll E2 causes the stops j to again resume their erect position, so Ithat they are ready for the next sheet. This rising of the stops j under the sheet beinr fed has no effect on that sheet other .than to ift a S11 hay from the table,
In duplicating-macines heretofore made, as far as known to me, the stopping devices for the hand-feeding of the paper have been placed to the rear of the plane running through the axes of the printing-cylinder and its coacting roll. This necessltates feeding by hand to a position beyond this plane and makes it necessary for the rintingto begin not less than some consi erable predeterminde distance from the edge. By putting the hand-feeding stop in front oi this plane and then feeding the remainder of the preliminary sheet movement by the action of the device itself I can release the sheet at any desired point, and thus have the printing begin very close to the margin.
What I regard as new, and desire to secure by Letters Patent, is-- 1. In a duplicating-machine, the combinai tion of a stencil-carrying cylinder, means for operating said cylinder, arms pivoted to the cylinder, a feeding cross-bar connectin the ends of the arms, s rings connected wit the arms for outwardiy projectingthe feeding cross-bar, and a feeding-table adapted to have sheets of paper moved thereover to be contacted by the feedin cross-bar under tension of the springs and acI sition, substantially as described.
2. In a duplicating-machine, the combination of a stencil-carrying cylinder, means foroperating said cylinder, arms pivoted to the cylinder, a feeding cross-bar connectin the ends of the arms, s rings connected wit the arms for outward yv projecting the feeding cross-bar, la feeding-table adapted to have sheets of paper moved thereover to be contacted by the feedin cross-bar under tension ofthesprings and a vanced into cprinting' position, and an abutment adapte tacted by the feeding mechanism after the paper has been carried into printing position. substantially as described. f
3. In a duplicating-machine, the combination of a stencil-carrying cylinder, a feed-ta vanced into printing poacting togther.

4. ln a duplicating-machine, the combination of a stencil-carrying cylinder, a roller slidably mounted in suitable proximity thereto, a link connected with the roller, an arm connected with the link, a cam, a connection between the arm and the cam for actuating the arm, a longitudinallyextending shaft, stops mounted thereon, a printing-table in suitable proximity to the stops, and a connection between the shaft and the link for operating the roller and stops simultaneously, substantially as described.
5. In a duplicating-machine, the combination with a stencil-carrying cylinder, and me ans for operating it, of a stop against which paper is fed by hand, means for remov said stop so that the paper may be advance from the hand-fed position to a printing po sition, and `an arm carried by said cylinder and arranged to so advance the aper.
6. ln a duplicating-machine, the combination with a printin `cylinder, and a stencil carried there y, of eviees furnishing a stopping-point to which paper is fed byhand, automatically-operating devices for moving the paper from the hand-fed position to a second stopping-point,l and means for moving the paper from the second stopping-point to engagement with the cylinder.
7. In a machine of the class described, primary and secondary stopping-points to which paper is fed prior tothe beginning'o the printing operation, means by which the paper may be fed by hand to the primary stopping-point, and mechanically-operating means by which the paper is f ed from the pri-` mary to the secondary sto ping-point.
