I l atented Dec.,.26,
Application filed May 29, 1915. Serial No. 31,253.
To aZZ wi'wm it may concern: I i
Be it known that I,-RICHARD MARX, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Hectographs, of
which the following is a specification.
One object of my invention is to provide aduplicating or copying machine whose construction shall be relatively simple, substan tial and practical and which shall have its parts so arranged as to permit of its easy operation and convenient ad ustment.
A further object of the invention is to provide a novel form of table structure for a hectogra'ph and particularly one in which the surface from which impressions are taken is in the form of a web extending from a roll over said table to a second roll; the invention also contemplating novel means for controlling the. movement of the web over the table."
Another object of the invention is to provide a hectograph of the above noted type with novel means for gaging the position of the sheets of paper to be printed, as well as to improve the detail construction of the machine as a whole. j
These objects and other advantageous ends I secure as hereinafter set forth, reference being had to the accompanying drawings, in which,
Figures 1 and 2 are respectively a side elevation and a plan of a machine constructed according to my invention; Fig. 3 is a transverse vertical section of the machine shownin the other figures; and Fig. 4 is a fragmentary detached perspective view of the driving end of one of the spindles and its associated journal.
In the above drawings the frame of the machine is shown as consisting of two trans verselyextending end members in the form of castings 1 each including two legs 2 and rigidly connected by angles 3 which define the opposite sides of said frame. On this body or frame is mounted the table top which'consists of a fiat plate 7 of aluminum or other suitable metal extending the full length and breadth thereof and having a felt or other more or less soft fabric cover 8 whose edges extend down around and under the edges of the plate? where they. are clamped between said plate and the adjacent surfaces of the frame. Said cover is thus retained in a smooth, more or less the plate 7;
stretched condition over. the topsurface of which impressions are of a. paper or similar The web 10 from to be taken consists body portion provided with asuitable coating and is shown as passing from a roll 11 over a guide roller 13 at one end of the machine, thence over the flat fabric cover 8, around a second guide roller 13 at the opposite end of the machine to a second roll 12.
The first roll 11 is mounted upon'a spindle 14c removablysupportedupon a pair of ournals 15 and 16 of which the first is carried by a bracket 17 depending from the frame adj acentone end of the machine. The second journal is carried bywa bracket 18 likewisedepending from the body and preferably made of more or less resilient material permitting it to be drawn out of engagement with the end of the spindle 14. The journal 15 has fixed to it a ratchet wheel 19 and a crank handle 20, while on the bracket 17 adjacent said ratchet wheel is mounted a pawl 21 so placed as'to coact therewith. This pawl has a projecting arm engaging a cam 22 carried on ashort shaft journaled in the bracket'17 and having an operating head '23. Said cam is preferably oblong in form, being'so placed that when the pawl arm is in engagement with one of its long sides said pawl is'in position to hold the ratchet wheel from turning while when said arm rests upon one of its short sides it is raised out of engagement with said cam 22. The bracket 18 like the bracket 18 is made of resilient material and may be sprung away from the spindle 14 to release the same. I
At the ends of the machine there are provided covers 25 for the web where it leaves the table top and passes around the rolls l3 and 13 respectively, and each of these consists of a pair of side frames 26 pivoted or hinged to lugs 27projecting outwardly from the legs 2. The two side frames 26 of each cover have their upper parts connected by a suitable body 28 of sheet metal which extends over the outer side and top of the roll 13 or 13 as the case may be, and terminates in a flat extension 28 immediately adjacent and substantially parallel with the table top.
This extension is connected to the body by a vertically projecting portion 28 at right angles to it, and obviously either of the covers may be swung on its pivots away from the table so as to expose the roll 13 or 13,
with that portion of the web which passes adjustable abutment 32 is held adjacent around the same.
The top of the plate 28 of ers 25 is provided with an 30 for the reception of a bolt one of the covelongated slot 31 whereby an the top surface of the flat extension 28 with a flat face in a plane at right angles to the latter. Said bolt has a nut in the form of a head 33 whereby the abutment may be form of the large roll 11 is mounted upon the spindle 14 which is placed upon the two supporting journals 15 and 16, and the head 23 is so turned as to bring one of the short sides of its cam 22 into engagement with the adjacent arm of the pawl 21. The opposite end of said pawl is thus raised out of engagement with the teeth of the ratchet wheel 19 and the web is drawn from the roll 11 around the roller 13 (from whichthe cover 25 is thrown back,) being then led over the table top in engagement with the felt or fab- 'ric 8 thereon. The cover of the roller 13 being also swung out of the way permits the web to be passed around said roller and attached to the second spindle or roller 14: which is supported on the journals 15 and 16, after which the head 23 is turned into position to cause the cam 22 to lock the pawl 21 in engagement with its ratchet wheel so as to hold the roll 11 from further rotation. By means of its handle 20 the roller 14* is 1 now turned slightly until the web 10 lies taut over the table top, and the pawl 21 is caused to engage the teeth of the ratchet wheel 19 in order to retain it in this condition. The two covers 25 are then returned to the positions shown in Fig. 1, and a sheet having matter written thereon in suitable ink may now be laid face down upon thecoated upper face of the web 10, being positioned thereon by having its top end laid over one of the flat portions 28 and abutted upon the adjacent part 28 and the abutment 32. Bv any suitable means the sheet is pressed into engagement with the web 10 so that the latter is etched by the ink or other substance used in the writing, in the manner well understood in this art. After removal of the sheet and the application to the table top,
7 table,
' and around said the web of suitable printing ink, blank sheets may be pressed into engagement with said web after first being brought to the proper position by having one end laid upon the fiat part 28 of one of the covers and moved against the abutment 32 and the vertical part 28 Either cover 25 may be thus utilized to provide or support a gaging edge and whenever desired, the pawl 21 may be raised out of engagement with its ratchet wheel 19 and the roller 14 turned by means of its handle 20 so as to bring new portions of the web material 10 into position upon or if desired, the pawl 21 may be left in engagement with its ratchet and the pawl 21 raised so that some portion of the web which has already been etched or impressed, may be again returned into position for re-use.
/Vhenever it is desired to renew the felt upon the plate 7 the latter may be bodily removed from the machine by taking out the screws holding it in place. A new length of felt may then be stretched over the plate and after being carried around the ends thereof, may be clamped in position by setting up the holding screws whereby the top is held to the frame.
As shown in Fig. 4t, the spindles 145 and 14 which are usually made of wood, have on their ends circular metal plates 35, of which that designed for engagement with the journal 16 has a circular hole for the reception of the correspondingly formed supporting portion 36 of said journal. The plate at the opposite end of each journal however, is provided with a centrally placed rectangular opening 37 designed for the reception of the wedge-shaped extremity of the journal 15 through which power is transmitted from the handle 20 or 20 as thecase may be, when the web material 10 is to be wound thereon.
I claim 1. The combination in a hectograph of .a table; spindles supported under the table; guide rollers respectively at the ends of the table; a duplicating web passing from one spindle around one of the rollers across the over the second roller and to the second spindle; with sheet guiding and supporting covers for each of said rollers.
