SHERMAN PRINTING DEVICE Filed June 15 1922 2 Sheets-Sheet 2 Patented Apr. 1, 1924.' JOHN o. sHERMAN, on DAYTON, OHIO. PRINTING- DEVICE. ' Application led .Tune l5, 1922. Serial No. 568,601. 'wherein the printing plate is made up in a novel manner by meansoi' a number of pins or plungers held in a chase, and having their ends in a common plane with only those pins which form the desired letters or design projected beyond thepcoimnon plane. So tar as I am advised, this is a novel method of forming a plate and the impression given is varied in ineness of line by the dimensions of the'pins used. It is my object essentially to provide a )in assembly and chase wherein the proper c esign may be formed by projecting desired pins and the pins held under individually movable tension during the formation of the design, after which the chase is locked by a simple device to hold the desired arrangement. n i It is also my object to provide a sim )le printing machine having suitable means tor moving the chase, rectifying the pins with their p-rinting ends back int-o a common plane, and applying ink to thepins prior to making the printed impression. These various objects I accomplish by ,hat certain construction and arrangement ot' parts to be hereinafter more specifically pointed out and claimed. In the drawings, Figure 1 is a detail plan view of one corner of the device. i Figure Q is a section on the line 2-2 of Figure 1. Figure S is a detail elevation of the eccentric chase locking member.kv Figure 4 isa detail of one oi the pins. Figure 5 is a plan view ot' the chase by itself. y Figure 6 is a plan view of the complete machine. Figure 7 is a side elevation oiE the coinplete machine. Figure 8 is a detail end elevation of the one corner of the machine ony a larger scale. In my views l have not attempted to show the pins as small as they will usually be made. It will be understood that the dimension of the pins will be such that they form a dot on the object to be imprinted of the desired size and spacing. The pins shown are merely cylindrical tempered pieces ot' wire l having' their both ends flat. rf'he chase is made up of a rectangular frame having sides 2, 2, and sides 3, 3, leaving an open rectangular space within. The sides 2, 2, carry within the channels 2"L thereof bars 4, which are adjusted in position by set screws 5. The sides 3, 3, are 'formed with channels 3d responding to the channels 2. They have also channels 6 in the tops thereof. In the channels 3a are bars 7, which have pins 8 thereon, which pass through holes 9 in the bars 3. lVithin the top channels of the sides 3 are bars 10, 10, which have out out inclinednotches 11 therein which engage the pins 8. The pin assembly is arranged within the chase with the pins abutting each other and the. bars 4 are adjusted to lock the pins together, while permitting individual movement of ,the pins. When the bars 10 are pulled lengthwise toward the corner between ,themjthel bars 7 are forced inward against the pin assembly in such a way as to lock them tightly against any displacement. The manner of moving the bars 10 may be made simple by linking to the end of each bar a strip 12 and providing a mounting in the corner of the chase frame for a. shaft 13. The strips 12l Vare formed with apertures in theirI meeting ends, which lie over the eccentrics 14 and 15 on t-he shaft 13. These eccentrics are so arranged that when the handle 16 on the shaft is moved over the two bars 10 are pulled toward thel corner, thereby pushing in on the pins of the bars 7. In the embodiment illustrated I have formed a hollow at the select-ed corner of the chase frame, and extending the ends ot the bars 10 through holes in the ends of the channel spaces 6, into this hollow space. The sha-'ft extends across the hollow space and the eccentrics and links are mounted within the hollow space', as is the operating handle. The printing machine using the above chase is adapted especially for use with it, although it will be understood that the chase may be used in any desired manner. The machine frame has a bed 17 on which are erected standards 18 for shafts 19, one at each end of the frame. These shafts are connected together at their ends by means of arms 2O on the shaft and links 21 between the arms. At the corners of the machine beyond the shafts are b'ifurcated mounting lugs 22 for two lengthwise extending bars 23, said bars being connected together by rigid cross bars 24 coupling the ends together. The two bars 23 have apertures 25 therein, which are set over the shafts 19, said slots 25 being elongated to permit up and down movement to the bars. The bars have also projections or flanges 28 which engage over special shaped cams 26 on the shafts. Thus there is an engagement with the bars for each corner of the machine. rl`he cams have three iiats 27 at different distances from the shaft center. A handle 28 may be provided at a selected corner of the machine, said handle having a pin riding over a sector plate 29 having holes 30 therein for the pin. By means of the pin which is part of the sliding hand piece 31 on the handle, the shafts and cams can be located and held in desired position. As the above described method of holding the handle is common practice in many forms of machine I do not show the same in detail. rlhe chase is provided with rollers 32, which ride on the lengthwise bars 23, so that when the bars are raised by the cam device, the entire chase is elevated. The position ofthe bars is such that when the cam devices lower them to the lower point, the pins will all contact with the bed of the machine, thereby bringing them into a common plane. l/Vhen the bars are partially lifted up the desired design may be impressed on the upper face of the assembly thereby bringing the lower ends of the desired pins into projection in the same design as that impressed. In Figure 1 is shown a letter A impressed in the upper surface of the pin assembly and I have found that any object pressed into the assembly will result in the transfer of the exact impression or intaglio into an extension of like shape on the lower face of the assembly. The impressing of letters can be made by a typewriter as shown in my copending application, Serial No. 560,237. After this impression has been made the handle that locks the pins is swung to hold the pins in the depressed position. The chase is then in position with the pins all elevated from the bed, including those which have been depressed. The chase may then be rolled to the other end of the frame` which is usually about twice the length of the chase. As the chase travels across the center of the frame, the projected pins receive ink from a roller 40 supplied through a series of distributing rollers fed from a well l1 in the usual manner. lVhen the chase comes over the far end of the machine, it is lowered to the half way point again for making an impression on a piece of paper, fabric, or whatever is dedesired. This piece will be located on a tympan 42 mounted in the bed on a series of posts 43 set in holes in the bed, said posts having springs la set around them so that the tympan has some small movement as the chase isdropped. After the imprint has been made the parts are returned by raising the bars to their full height and rolling the chase back to the starting point, or at least far enough to receive another coating of ink to make another impression. The entire plate may then be dropped against the platen to rectify the pin assembly after the same has been freed. The motions are all applied to the pin frame or chase by means of the bars 23 Y which are raised and lowered by manipulating the handle 28, thereby operating the cams 26, which in turn act on the bars at the four corners of the machine. I have not attempted to describe more than one modification of my device, and do not desire that my claims be construed without the full application of the doctrine of equivalents because of my failure to point out other structures which will accomplish the spirit of the invention.
