FRANK AMOS JOHNSON, 0F DUNELLEN, NEW JERSEY, ASSIGNOR TO THE SIGNATURE COMPANY, OF NEW YORK, N. Y., A CORIPORATION OF NEW YORK.

MULTIPLE-WRITING MACHINE.

T 0 all whom it may concern:

Be it known that I, FRANK Amos JOHN- SON, a citizen of the United States, and a resident of Dunellen, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in lVIultiple-Vriting Machines, of which the following is a specification.

My invention relates to machines for si multaneously writing a plurality of signatures and more particularly to that class of these machines which are designed for desk use in the signing of checks, warrants and similar instruments. In these machines from four to six pens are ordinarily secured to a common, rigid pen-bar and it is necessary to have a perfectly flat platen or writing surface in order to secure the best results. Where an ordinary table or desk is used to support the documents while the signatures are being affixed the surface is often so uneven that some of the pens will not write. I have devised a box-like housing which serves as a base on which to mount the writing machine itself and I utilize the cover of this box for a writing platen. This cover is made with special care to secure as near a perfectly flat surface as possible and it is attached to the box by strong hinges so that the cover and pen-bar are maintained in exactly the same relation at all times. Furthermore, that portion of the cover on which the writing is actually 1 done, is made of a separate piece which is perfectly flat and this is secured to the cover in such a manner that it cannot be affected by the subsequent warping or twisting of the cover. The attachment of the machine proper to the housing is made in such form and the machine is so constructed that the pen-bar may be reversed and temporarily latched up with the pen points upward, far enough above the writing surface to permit of easy access to place and adjust the documents for signing. The whole writing machine is detachably secured to the housing, so that it may be readily removed for cleaning or repairs when necessary. The machine has a longitudinal adjustment on the housing so as to write at the extreme top or the extreme bottom of the documents and the pen-bar and its supporting arms have a vertical adjustment so that the pens may be set to write on a single sheet, a thin pile, or a Specification of Letters Patent.

thick pile, as in a book. When not in use the machine may be folded away in the box housing which, after the cover is closed, becomes a convenient carrying case. Improved means is also provided for attaching the pens to the pen-bar. These improvements and other novel features of construction will be fully pointed out in the description which follows and in the claims, reference being made to the accompanying drawings, in which:

Figure 1 is a plan, with the cover opened up and the penbar in position for writing; Fig. 2 is a left elevation of the machine, with all the parts in the same position as shownin .Fig. 1; Fig. 3 is a front sectional elevation on the line i\--A of Fig. 2; Fig. t is a front sectional elevation, the same as Fig. 3, but with the pen-bar temporarily latched up above the writing platen, the pilot handle being removed; Fig. 5 is a frontsectional elevation on the line BB of Fig. 1, showing the cover closed and the machine folded away for storage or carrying; Figs. 6 to 9 inclusive are all enlarged detail views of the pen clamp, Fig. 6 being a left side elevation, Fig. 7 a front elevation; Fig. 8, a right elevation; Fig. 9 a cross section on the line C C of Fig. 8-a portion or a section of the pen-bar being shown with each view. Fig. 10 shows the method of attaching the pilot handle to the pen bar.

The housing, which serves as a base or support for the writing machine, the cover of which is used as a document support or writing platen, consists of top portion 1, bottom 2, right side 3, front and rear walls t and cover portion This latter portion is attached by hinges (3 to the bottom 2, supported by two strips 7, which serve as feet to raise the box high enough to permit the cover being opened up to horizontal position.

The cover 5, has a recessed portion Fl, in which is loosely fitted a flat plate 9, used to support the documents 10, under that portion at least, on which the signatures are to be allixed. Plate glass has been found to be admirably suitable for this purpose. The recess 8 is deeper than the thickness of the plate 9 and the plate rests on a front ledge 11 which extends the full width of the plate and on a rear ledge 12, which is short and which is central with the plate. These ledges support the plate 9 so that its outer surface is flush with the cover. Front and rear screws, the heads of which overlap the glass, hold the plate in place. It will be seen from this construction that any warping or twisting of the cover will not affect the plate 9 and that a flat writing platen is always presented.

The documents to be signed are located in any desired position on the cover by marginal steps or gage pins 14 which are secured in holes 15 in the cover 5.

The cover is locked in its horizontal position by a pair of toggle links 16, which are pivotally connected by hinge pieces 17 to the cover 5 and the rear wall of the box.

The pen-bar 18, which carries the pens or writing members 19, is held touniversal movement in a horizontal plane by parts which make up two parallelogramsone having pivoted or ointed sides and the other having rigid sides but swinging axially on one of those sides, as follows: A pair of parallel links 20 pivotally connect the penbar to a swinging rock-shaft 21. These links are forked at each end and attachment is made to the pen-bar by pivot, center screws 22, which have bearings in blocks 23 secured to the pen-bar. Attachment is made at the opposite end to the swinging rockshaft by center screws 22 which have bearings in posts 24 in the rock-shaft.

Above the swinging rock-shaft is a fixed rock-shaft 25 which is axially pivoted and mounted in any convenient manner rigid with and substantially parallel to the document support. This shaft has a pair of arms 26 which are connected by a tie rod 27 to give greater rigidity and strength. The swinging rock-shaft is axially pivoted between the lower ends of the arms 26, on center screws 28.

The pen-bar, with its pens, the rock-shaft 25 and the intermediate connecting parts which have already been pointed out, const-itute the main or essential elements of a multiple writing machine as herein embodied. The mounting of the shaft 25 may be made in a great variety of ways, any of which would make the writing machine operative so long as the shaft was axially pivoted in the position described. I have shown a mounting or means of attaching the essential parts of the machine to the housing which holds these parts rigidly when in,

writing position, which is capable of both vertical and longitudinal adjustment and which, as already stated, permits of the parts being folded away in the box. This mounting comprises a pair of arms 29 which are rigidly secured to a shaft 30 and connected by a tie rod 31. The rockshaft 25 is axially pivoted by center screws 32 between the outer or free ends of the arms 29. The shaft 30 is mounted in brackets 33 secured to a base bar 34 and the base bar is held on the under side of the top 1 of the housing by a pair of clamps 35 controlled by screw and thumb nuts 36.

The bar 34 has at its front end a depending, angular bracket 37, which carries at its bottom end a plate 38 provided with a series of adjusting notches 39. An angular guide rail 40 fastened to the bottom of the housing enters a notch 41 in the plate 38 to stiffen the structure and still permit the whole to be moved forward or backward.

The outer or free ends of the arms 29 of the mounting frame which carry the rockshaft 25 are supported by a pair of toggle links 42 and 43. A specially made check nut 44 for the front pivot screw 32 serves as a pivot for the link 43 and the lower end of the link 42 is held by a screw 45 which has a thumb nut 46, by means of which the link 42 is pivotally connected to the plate 38 in one of the notches 39. \Vhen the machine is in writing position the toggle is held locked by a latch spring 47 which is attached to the link 42 and which engages near its upper end a pin 48 of the curved link 43. This link is curved to permit of the parts being more readily folded away in the box.

From the construction which has just been pointed out it is evident that by loosening the thumb nuts 36 that the mounting bar and its frame and all connecting parts may be readily adjusted front and rear to any desired position and that, by putting the screw 45 in the various notches 39, that the shaft 25 may be set in four different positions as regards its height.

Each of the pens is attached to the pen- 7 bar by a pen-clamp. Each of these clamps has a band port-ion 49 which encircles the pen and is provided with a clamp screw 50. This pen band is riveted to the vertical portion of a right angled piece 51 which is provided with a recess 52 in which the band is fitted tightly and where it is firmly held by a rivet 53. On the opposite side of the vertical portion of the angle part 51 there is a stud or pin 54 to which is secured a spring 55. The horizontal part of the T-shaped pen-bar has a slot 56 cut on its upper side, its entire length and the horizontal portion of the angle 51 is provided with two screws 56 and 57. Both screws are adapted to enter the slot 56 of the pen-bar. The screw 56 may be set up quite tight or left so that there is just a running clearance between it and the stud 54; in which case the penclamp may be moved along to any position on the pen-bar-being held by the tension of the spring 55. The screw 57 is knurled and acts as an adjusting screw for the pens by rocking the clamps against the tension of the springs 55. These pen-clamps are made as light as possible and are formed preferably of aluminum. In the improved construction which has just been described a maximum of strength is obtained with a minimum amount of weight and the pen bands, being formed from sheet aluminum, are flexible and they are capable of wide adjustment for unevenness in the size of the pen barrels without any danger of breaking.

The pen-bar is guided by a pilot handle 58 which has a ball and socket (SO-the latter being secured by a socket band 61 to a slotted link (32. This link is adjustably secured by a clamp nut 63 to the front end of the pen-bar. The socket G0 is provided with an adjusting screw 6 1 which is adapted to strike against an incline (35 of the link 62 and by means of which all lost motion can be taken up. Throughout the machine free motion is necessary, but all lost motion must be eliminated.

The whole or a large part of the weight of the pen-bar and pens is carried by a supporting spring 66, the lower end of which is attached near the end of an arm 67, which is secured to the rock-shaft 21. The attachment is near the end rather than at the end in order to prevent the spring getting caught in an unnatural position when the parts are in the position shown in Fig. The upper end of the spring 66 is attached to a compensating lever (38. This lever is fulcrumed on the tie rod 31 of the mounting frame and it has a pin (39 which bears against a cam piece 70 which is secured to the base bar 84. The object of this construction is to make a compensating support for the spring, so that, as the shaft 25 and its connecting parts are raised by putting the screw 45 in the upper notches of the plate 38, the tension of the spring will not be changed. The parts are first adjusted so that the pen-bar will just clear the writing surface and so that the arms 26 will hang in a vertical position. This is done by getting the spring (36 the right tension and by hitching it in one of the series of holes 71. in the outer end of the compensating lever (58. This is the normal, central position and as the pen-bar is carried to the right or to the left the parts tend, by reason of their weight, to return to this position. To overcome this tendency and to produce a perfectly balanced pen-bar the fixed rock-shaft 25 is provided with an arm 72 to which is pivoted a curved link 72*. This link is con nected by a spring 73 to an extension 741; of the height adjusting screw 45. The arm is positioned so that when the parts sup ported by the spring 66 are in the central position, the spring 73 will draw directly across the pivotal axis of the shaft 25 and there will be no tendency to turn the shaft; but as soon as the pen-bar is carried to the right or to the left, the spring 73 acts to hold the parts in the position to which they are moved. pen-bar which at all times literally floats and which is absolutely inert.

The parts may be thrown into the position shown in Fig. 4, to permit of the placing or adjusting of the documents to be signed, the compensating lever (38 acting as a support for the pen-bar.

WVhen not in use the parts may be folded away as shown in Fig. 5, by releasing the spring 47 and breaking the supporting toggle. In'this position the swinging rockshaft 21 rests on a block 7 5 which is attached to the bottom 2 of the housing and an elastic loop 76, which is attached to the side 3 of the housing, may he slipped over the penbar to hold the parts in place. The cover may then be closed by releasing the toggle which secures it to the housing and when closed it is held by latch springs 77 which engage pins 78 in the cover.

A carrying handle 79 is provided and the box-like housing on which the operative parts are mounted and which affords a writing platen, becomes a convenient carrying case.

By loosening the nuts 36 the clamps 35 may be released far enough to free the base bar 3a and the entire machine may then be removed from the housing.
