Application filed J'u`1vy`18, 1921, Serialv No. 485,569, and in Great Britain September 1,6, 1920.
This invention relates to printing presses for printing preferably from type, or it may bevused in connection with a stencil. The object lof the invention isto yprovide alight portable press which may be operated by hand. The invention consists broadly of a printing press comprising an inking roller forinking the type, vand a pressure roller for effecting the printing, the two rollers being so mounted that the operation of a reciprocable handle brings the inking roller into operation when the said handle is moved in one direction and brings the pressure roller into operation when it is moved in the reverse di- 1 rection, and the invention further comprises certain features `in the ink feeding `arrangements and the method of feeding the ink from a fountain to' the vdistributing roller andthence to the inking roller adapted to revolve'over the type to supply the said `type with ink on one operation of the reciprocable handle. y A
In order that the invention maybe clearly understoodk and readilycarried into practice, reference will nowbemadeto the accompanyingdrawings which illustrate a press constructed in accordance with the preferred embodiment ofkmy invention, and in which I Figure 1 is a perspective view thereof,"
Figure 2 shows an arrangement for ade justing the formr or chase, and Figure 3 is an end elevation, part of the frame or support being removed for clearness. Y
Referring to the drawings the numeral 1 designates the support carrying the `chase or form 2 in which the ytype vor stencil is carried. The support 1 isrpreferably hinged at its bottom end to a bracket 3 secured tothe base 4. By this means the press canbejfolded up and laid flat when not in use. f. When in action it stands uprightat asuitable angle and is made. unmovableby meansy of arms or standards 5 pivotally mounted at .6 to the support land provided with slots? at the lower end, they arms being released when it is desired-to fold up the press by unscrewing the nuts S. A fra-me 9 isA hinged at its eX-. treme end 1() to a bracket on the base, this yframe operates about the support 1 over which it swings. The lframe 9' carries a rocking frame 11 in which are journaled two shafts 11a and 12, and the frame 11 is journaled tooscillate in frame 9 on the shaft 13. An inking roller 14is carried on shaft 11 and a pressure roller 15 is carried on the shaft 12. Normally the inking roller 111 is held or retained in contact with the type during one operation or stroke of the arm 9, by means of a spring 1G on the shaft 13, one
endA ofsuch springbeing secured to an oper volve against the endless band.
Atthe upper end of the support 1 a trans'- lversely disposed actuating rodv 2e is supported in a pairof curved slots 24 with the ends of` this rod projecting beyond the support 1 in the path of` movement of the swingr frame 9. A cam plate ,25 "is pivoted on the rod and is fashioned with a cam corner 25 and acam slot 25a, into which slot a guide pin 25,
-port 1.
Meansare' provided for retaining the pa# per sheet in position `for making theimpression thereon; for opening and holding open said retaining means at the inking stroke to facilitate the insertion of a paper sheet; and for lifting the printed sheet from the form. For this purpose I utilize Aa somewhat U- shaped, pivoted,.spring pressed frame comprising apair of lifting plates 26 extending alongside the form, and hinged at 26 to the support 1. These side plates are connected by a transverse plate 263. at the top of the device, and at the ends the transverse plate are arranged a pair of spring` clips 252 for gripping the paper sheet at its upper ends and holding it during the impression stroke or printing operation.
In operation of the press,.assumingthe parts are in the position shown in Figure 1 and the full line position Figure 3 the handle 17 is raised and rotates about the centre 10 and carries the inking' roller 14 over the surface of the endless band and'subsequently over the surface of the type, thus inklng the type.'r As the arm' 9 reaches theuppermost position of its stroke itfengages the rod 24 which operates the cam plate 25, ar-
`protrudes, said pin being fixed on the supf ranged on each side to move the paper support 2G to the position shown in dotted lines .h "igure 2l, the 4Icorner 25 engaging a lipon the upper or gripper portion 252 oit the paper support and oi ening itl ont as shown, against the action of a spring 2t connected to the l'iinged plate 263,y to facilitate the inlsertion ot the paper which is subsequently held tightly by the gripper during the operas tion. oi printing. T he same movement of the cam plates Vcauses the inliing roller to rock in an upward direction assuming the position shown in dotted lines Figure 3, whilst at the same time the pressure roller assumes the desired position for the printing or downward stroke. A roller at each end ofthe inliing roller runs over cams I? near each end et the spring plate 26.3 to lift the inlring roller clear oi' the paper clip 263. By means oi a trip action including a latch 28 pivoted on handle 1T the rocking bars 1l are retained in this position against the action of the Spring 16 so that on the return stroke of the handle 17 the linking roller returns clear of the type, Whilst the pressure roller l5 which on the upward stroke was clear of the type, returns on its return journeyunder the guide rails 29 secured ateacli side of the 'machine eigercising suliicient pressure on the paper which has been inserted above the inked type, to give the requisite impression. When the operating handle 17 is passing the upper portion of the guide rail 29,"the lip 281 on the trip action engages the corner 291 of the rail 'thus releasing 'the' rocking shafts which when the pressure roller is clear of the guide rails enables the inking roller to again come into contact with the surface of the endless band. On completion of the downward or printing stroke the arm 9 contacts with and actuates a spring controlled lever 30 on which is mounted a ratchet and pawl mechanism. The toothed wheel 3l of the mechanism gears with the wheel 32 oi the lower shaft 19 on the endless band. The endless, band, by means of the gearing, is caused to travel forward va certain extent with each operation or impression so that the inling roller travels over Ya certain amount of 'fresh surface each time.
The chase containing the type can be brought nearer to or further away from the rollers, to regu-late the amount of pressure, o r allow ini" printing different thicknesses of paper. A convenient device for this purpose is shown in Figure 2, and it will be readily understood that on rotation oi' the nuts 38 causing movement of the pins SLL the cams 35 are operated and so raise or lower the :torm or chase 2 carrying the type 21 nearer or further away'froni the pressure roller.
As the frame 9 is swungupwardly, near the end of its rip-stroke, it encounters the laterally projecting end of rod 24, at the right in Figure l, Continued movement ot the liframe 9 in contact with this end of the rod causes the rod to slide in slots 24e oi: the stationary frame l. The rod carries with it the cam plate 25 (F ig. which is slotted at 25a for cO-action with a guide pin 25D of the frame l. rlhis bodily movement of the Cain plate causes its lower end to swing upwardly, and in its upward movement the plate which has one edge normally located beneath the lifting plate 2t, swings the plate 28 as indicated in dotted lines, to open position to remove a printed sheet and to thereby permit insert-ion of another sheet in proper place on the forni. The free arms of the clips 263 are also. swung on their 'ivots 2G by this movement of cam plate 25, as indicated by dotted lines in Figure l to release the printed sheet.
lVhat I claim and desire to'vsecure by Letters Patent is :e
