T0 all whom t may concern.'
Be it known that I, CHARLES W. JEAN, a citizen of the United States, residing at New York` in the county of New York and State of New York, have invented certain new and useful Improvements in Copying- Machines; and 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.
This invention relates to presses, and more particularly to those employed for copying as from a typewritten letter; and the object of the same is to produce a machine of this kind in which the days letters may be rapidly copied onto a web of moisteiied tissue, the same then dried, and finally the ,dried web cut in standard lengths corresponding to that of the letters and each duplicate sheet of tissue perforated with holes for binding by means of the prevailing system.
The machine includes an upright power shaft which is rotated constantly by a prime mover such as an electric motor, when the current is turned on; a master shaft, and a clutch between it and the power shaft; moistening, wringing, pressing, and feeding mechanisms whereof each includes a pair of rollers and one of which is positively driven from the master shaft so that the tissue web whether wet or dry will be moved always at a uniform speed. a timing mechanism also driven from said master shaft; a manually controlled mechanism for simultaneously closing the clutch and releasing the timer, so that when the latter makes a complete revolution it automatically' reopens the clutch; a drying mechanism between the presser rollers and the feeder rollers, and a cutting mechanism connected with said manual control-all as hereinafter more fully described and claimed. and as shown in the drawings in which:
Figure 1 is a side elevation of the device constructed in accordance with this invention,
Fig. 2 is a vertical sectional view therethrough, showing parts in elevation,
Fig. 3 is a side elevation of a portion of the machine from the opposite side from that shown in Fig. 1,
Fig. 4 is a vertical sectional view as on the line 4 4 of Fig. l, and
Fig. 5 is a perspective view of a portion ofA the machine showing the perforating and cutting mechanism.
In .the use of tissue paper to receive a copy impression thereon in a moist state. 1i is necessary that certain provisions be made for the handling of the tissue web in the most efficient manner to prevent tearing and also to reduce the lengths of moist areas to a minimum as well as to provide a universal movement of all the parts of the web.
Referring to the drawings in which similar reference numerals indicate similar parts throughout the several views, there is shown a stand comprising the legs 10, cross bers 11 and fittings 12 on the upper portion thereof, which fittings are connected bv the cross piece 13 to form a rigid structure Bearings 14 are provided upon serre of the bars 11 to support a roll of paper 15 having the usual tension device 16 which nia" be adjustable to meet the requirements. From the roll 15 the web 17 passes over a roller 18 journaled in bearings of a frame 19 from where it passes between the meistening rollers 20 and 21 which are also sup` ported by bearings in the frame. The latter has a reservoir for a Quantity of water to moisten a fabric covering upon the rolle 20 so that as the web 17 pasf'cs betwfc" 'h rollers Q0 and 21. it is moistenod to J-rl`e "c sired degree. After leaving the roller 21 the web passes between the wringi g rene". 22 and 23 journaled in brackets 94 v'h'ci are attached to vertical standards 95 ri"i"9 from the cross piece 12. The roller 03 if' movably mounted in the brackets 24 and is held in engagement with the roller 22 under normal conditions by the compression spring 26, but when so desired. is mciefl from engagement with the roller bv the thumb nuts 27 on the screw eye"- 28 which support the trunnions for said roller and also pass through extensions on the brackets 24. In passing between the rollers 22 anfl 23, the surplus water is removed from the web and the degree of moisture may be controlled by manipulation of the win g nuts 27.
After passing from the roller Q2, the web passes between the pressing rollers 29 and 30 of which the roller 29 is journaled in fixed bearings carried by the standard 25 and the roller 30 is movably mounted, being carried by the ends of the levers 31 which are pivoted as at 32 to the .standards and from which extend the arms 33 to support a handle 34. Movement of the handle 34 varies the contact of the rollers 29 and 30 upon the web 17 and likewise creates the impression upon the web 17 as a letter written with the ordinary copying ink is also passed between rollers 29 and 30. Thumb screws 35 are carried by the brackets 36 to establish the desired compression between the rollers 29 and 30 by releasing or depressing the arms 33 as the case may be.
After leaving the rollers 29 and 30 and having the impression made thereon, the web passes to a drying cylinder or drum 37 in which a gas or other heater 38 is mounted and to cause the desired contact of said web with the drum 37, a roller 39 bears upon the drum 37 from above, while a roller 40 engages the lower portion of said drum so that the paper binds against said drum for the major portion of its circumference. The rollers 37, 39 and 40 are journaled in standards 41 which are also formed on the cross pieces 12 and roller 39 is removably mounted in the upper end of said standards.
Upon leaving the roller 40, the web passes to the feeding rollers 42 and 43 which are j ournaled in brackets 44 carried by the legs of the frame and the roller 43 is adjustably mounted so that the compression spring 45 may bind the roller 43 against the roller 42.
Like the roller 23, the roller 43 has its trunnions mounted in screw eyes 46 which receive the wing nuts 47 after passing through lugs 48 of the brackets 44. These feeding rollers advance the web to a perforating and cutting device which comprises a fixed blade 49 carried by the frame and a movable blade 50 which is pivoted as at 51 in a hub carried by the support for the blade 49. The cutting members 49 and 50 support perforating members comprising the plate 52 in which the punches 53 are set and the plate 54 in which holes 55 are formed to co-act with the punches 53 in perfcrating the end of each individual sheet formed from the web by the cutters 49 and 50. As tissue paper is dificult to handle satisfactorily, a movable plate 56 is provided through which the punches 53 pass and this plate is supported as by pins 57 passing loosely through the plate 52 and having compressionv springs 58 thereabout, to normally move the plate 56 beyond the ends of the punchers 53 so that after the ends of the sheets are perforated and the blade 50 swung to the position shown in Fig. 5, the plate 56 removes the end of the web from about the punches 53. Y
A motor or other prime mover 59, is mounted upon a motor board 60 which in turn is carried by some of the cross bars 11 andthis'motor has a worm 61 on the shaft thereof, which meshes with the worm gear 62 carried by an upright power shaft 63.
The shaft 63 has its lower end journaled in a bearing 64 and its upper end in a sleeve 65 which sleeve is journaled in the bearing 66 and said shaft has a clutch member 67 splined thereon to permit sliding movement of said clutch for engagement with a clutch 68 formed on the sleeve 65. The sleeve 65 supports a beveled pinion 69 which meshes with the beveled gear70 carried by the shaft of the roller 29. The opposite end of this, which might be called the master shaft, M carries the spur gear 71 which through the idler 72 drives the gear 73 on a timing shaft 74; and in addition to the spur gear 71, the master shaft M also carries a beveled gear 75 with which the pinions 76, 77 and 78 carried by the shafts 7 9, 80 and 81 respectively, engage to impart motion to the several shafts. The rollers 22, 20 and 42 have beveled gears 82, 83 and 84 respectively, carried by the ends of the shafts of said rollers and these gears mesh with pinions 85, 86 and 87 respectively carried by the shaft 79, and 81. It is seen that as the master shaft M is rotated by the motor 59, the rollers 20, 22, 29 and 42 are driven at a uniform speed so that the paper contacting with these rollers in the order named, moves uniformly throughout its length without fullness or slack and without wrinkling or tearing, even though it be moist.
While in operation, the armature of the motor 59 and the power shaft 63 run continuously and when it is desired to make a letter copy, the clutch members 67 and 68 are brought into engagement, but as soon as the predetermined length of the web 17 is passed between the pressing rollers 29 and 30 to receive the impression, the clutch members 67 and 68 are automatically disconnected until such connection is restablished periodically to advance the copy to the cutters 49 and 50 which in ordinary usage would be by the continued operation of copying letters. This clutch mechanism is closed by a manually operated lever and held closed for a certain period by a timing mechanism described in the following manner: Atreadle 88 pivoted as at 89 to one of the legs of the stand has a pin 90 which works in a slot 91 formed in the lower end of a lever 92 which is fulcrumed as at 93 to one of the cross bars 11. The upper end of the lever 92 passes through an opening in the slidable bar 94 which is carried in a guide 95 having the slots 96 and 97 formed therein to permit freedom of movement of the lever 92 and the lower end of the arm 98. This arm extends from a hub `99 which is pivoted as at 100 to a bracket one arm 107 of an inverted U-shaped yoke.
The bell-crank lever comprising the arms 104 and 105 is fulcrumed as 'at 108 to a bracket carried by one of the cross bars 11. rIhe Vyoke-arm 107 carries a fork 109 to en- 'gage the clutch member 67 so that as the arm 107 is raised, theclutch member 67 is likewise raised and when the treadle 88 has been depressed through the mechanism just described, the clutch members 67 and 68 are thrown into engagement. To hold said clutch members in engagement for a given time, a timing wheel 110 is attached to one of the ends of the shaft 74 and this wheel has a notch 111 in its periphery to receive a roller 112 carried by the bend of said yoke. Beyond such bend the yoke is continued downward in a second arm 113 which is maintained in vertical position by having the lower end thereof pass between the guides 114 carried by one of the cross bars 11. In the action of the parts ust described, when the operator depresses the treadle 88 motion is communicated to the bell-crank lever, the latter lifts the yoke, and the rise of the yoke causes its fork 109 to throw the clutch members into engagement. rIhe various parts lof the machine then immediately begin their movements, and the timing wheel 110 commences to rotate, as the rise of the yoke has lifted the roller 112 out of the notch 111. The removal of pressure from the treadle permits the yoke to drop back part way, but it is checked by the roller 112 resting on the peripheryV of the wheel 110. The circumference ofthe latter is equal to thelength of the standard letter sheet, and therefore during the revolution of the timing wheel just that much of the tissue web is drawn through the machine. As 'soon as said wheel has made one complete revolution the roller lfalls again into the notch 111 which permits the yoke to drop back to its original position and as it does so the fork 109 disengages the clutch members so that all parts o f the machine except the motor and power shaft come to rest again. Theremoval of pressure from the treadle and the retraction of the bar 94 also actuate the cutting mechanism which severs a standard length from the rear end of the web and punches holes abovethe line of out so that they will be at the top of the tissue sheet next to'be cut from the web when the operation is repeated.
The end of the sliding bar 94 is connected as by the arm 115 .tothe rook shaft 116, journaled'in the sleeve 117, andsaid rock shaft has an arm 118 which Lis connected as by a link 1,19 tov an arm120 vformed 4on the lower end of the pivotfor the cutter blade 50 so that manipulation of the treadle tor set the mechanism into operation also Vserves to separate the. cutter members which are brought into voperation to sever the sheet from the end of the web as soon as the timing wheel 110 has made a revolution. The perforating mechanism coperates with the cutting mechanism as is clearly understood.
