' PRINTED-SHEET-REOEIVING TABLE FOB PRINTING-PRESSES.
No. ae7,ee4. f
To ,all whom# may commi: A
Be it known that I, FRANK W. Tnonss, a citizen of the United States, and a resident `of Toledo, in the county of Lucasand State of Ohio, have invented a" certain new'and useful Printed-Sheet-Receiving Table for Printing-Presses; and I 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, ref erence being had to the accompanying4 drawings, and to the figures of reference marked thereon, which form a part of this specification.
My invention relates to attachments for printingpresses, and particularly to a table or 4device for -re- 'ceiving the impression-sheets after they have been printed. 'r
y In the running of printing-presses it has heretofore been customary to successively" place the printed sheets on top of each other in the order in which they are taken from the press, thus causing an off-setting of .Y the wet impressions from each sheet to the one next press to 'paper between the-printed sheets until the same are dried.
The object of mylinvention isto obviate this off-setting and to save the expense and labor incident to slipsheeting by the provision, in association with a press, of simple and eflicient means having a plurality of sheet-receiving pockets or trays and movable to successively bring .the pockets or trays in position for the operator to successively deliver the wet sheets, as they are taken from the press, to different ones thereof, thel number of pockets and movement thereof being so regulated that after a sheet has been delivered to a pocket such pocket is not brought in position to receive 'another sheet until tire impression on the sheet previously placed thereinis sufficiently dried to prevent ofi-setting.'
The operatiomconstruetion and arrangement of the parts of the invention are fully described in the following specification and illustrated in the accompanying drawings, inwhichf- I Figure 1 is a perspective view of the mechanism comprising my invention anda portion of an associated jobwhich it is Fig. 2 is an enlarged perspective view of one of the pockets with a reducing membe therein. Sisaside elevation of the oper- -ating mechanism anda portion of the associated press,

and partially broken away, and lFig. 4 is a bottom view of the bearing-sleeve projecting from the und er side of the table. y
Referring to the drawings,l designates the main or ldrive-shaft of a job-printing press, and 2 and 3 the usual balance-wheel and belt-pulley, respectively, carried by said shaft.
At one side of the pressl in convenient position for the operator to deliver the printed sheets thereto as they are taken from the press is located a revolving table 4, which carries adjacent its edgea series of concentrically arranged pockets or trays 5 for successively receiving the printed sheets as they are taken from the press. These pockets ortrays are shown as consisting of a rectangular bottom and two adjoining sides and as being supported by the table in tilted relation thereto with the vcorner formed by the two sides lowered and disposed toward the center of the table and the diag- .onally opposite corner elevated, thus enabling the sheets as they are placed therein to slide inwardly sides of the pocket, thereby uniformly straightening themselves.
The table 4 is rotatably supported by a stationary vertical shaft 6, which has its lower end mounted in a standard 7 secured t0 the door. This shaft has its upper end projecting within an enlarged sleeve 8, rigidly projecting from the under side of the table, and is provided at such end with a conical socket for loosely receiving the conical end of a centering screw or pin 9, which is carried by a plate 10 and 'projects axially secured to the top of the table by bolts 11, which are shown as also securing the sleeve 8 thereto.
-Lo'osely mounted on the shaft 6 beneath the sleeve 8 is a worm-gear 12, which is supported by a collar 13 in position for its upper face to frictionally engage .the lower end of said sleeve. This collar is fixed to the shaft 6 and has a stud 14 projecting laterally therefrom and carrying a bearing-bracket 15. Snitably mounted in this bracket is the horizontalworm-shaft 16, which carries the sprocket-wheel 17 and the worm 18, the latter meshing with and driving the worm-gear 12'. Rotation is communicated t` the shaft 16 from the driveshaft 1 of the press by the sprocket-chain 19, which connects the sprocket-wheel 20 on the shaft 1 with the sprocket-wheel 17. The outer end of the shaft l is braced by a standard 21, which rises from the door and carries the opposing journal-blocks 22.
23 designates an idler-roll whichyieldingly coacts with the chain 19 to take up' any slackness therein. This roll iscarried by one arm of an angle-lever 24, which is fulcrumed to the standard 21, as at 25, and
compression-spring 26, which has its thrust against the standard 21 and said latter arm.
until the inner adjoining edges thereof strike the two through`the table, as shown in Fig. 3. The plate 10 is In order to increase the'irictional resistance of the' operate, said pins or detents being threaded through orotherwise suitably set in the worm-gear l2, as shown in Fig. 3. The upper surface oi the worm-gear l2 has its hub portion extended, as shown :1t-2i), to form a bushing which projects within lthe lower end of the sleeve 8 and centers it relative to the shaft 6.
The table may be hoisted from the shaft 6 pending a rope or other hoisting'm cans above the table and attaching it to the eye of the lifting bracket 30, which is secured to the top of the table.
Should sheets of smaller size than the pockets or trays 5v be printed, a reducing pocket or tray 31 of suitable size may be positioned in the pocket or tray 5, thus causing the outer edges oi' the sheets to register with the corresponding edges of the tray. The reducing trays are made in different stock sizes and each comprises a bottom which completely covers the bottorn of the trays 5 and two adjoining sides, which are properly positioned relative to the sides of the tray 5 to suit the size of the sheets being printed.
The operation of the apparatus is as iollowsz--Should the table 4 be provided with eight pockets or trays 5, as shown in the drawing, the speed at which the table is driven relative to the connected press is so timed that one-eighth of a revolution is imparted to the table at each printing operation oi the press, thus successively moving the pockets in position for the operator to deliver a printed sheet to each as it is taken from the press so that each pocket will receive one sheet at each revolution of the table, providing, of course, no impressions are missed. By the use of rapid drying ink it is found that the impression on a sheet is sufiiciently dried during one revolution of a table employing eight pockets to prevent an offsetting of the imby sus pression on the next sheet when placed thereon. It is understood, however, that the number of pockets employed and the consequent speed of revolution of the table depends upon the length oi time required to properly dry the impressions. It will also be understood that while I have shown and described a particular construction andarrangement of the parts of the invention, I do not desire to be limited thereto, as obvious modiiications will occur to a person skilled in the art. A
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,-
1. 'ihe combination with a printing-press, of n rotatable member turnable on u vertical axis, u series of tilted sheetreceivini.: parts carried by said member, and mechanism driven by the press for rotating the member ut u predetermined speed to successively bring the sheet-receiving parts in position for each to receive only one printed sheet at each revolution of the member. i
2, 'ihe combination with a printingfpress, of a rotatable member having,r a vertical axis, a circular series of sheetreceiving pockets carried by said member und mechanism driven by the press for continuously rotating the member' :it a predetermined speed to successively brim.: the sheetAreceivini: pockets in position for each to receive one printed sheet at each revolution of the member.
2i. in combination, a vertical shaft, u geur carried by the shaft, a table revolubly supported by the shuit and huvim.: a part loosely receiving the upper end of the shaft und lluving its lower end resting on the geur whereby rotation is frictonally communicated thereto from the geur, und mechanism for driving the` geur at u predetermined speed.
4. The combination with u printing-press, of u. table mounted at the side thereof und revoluble about a vertical axis, mechanism for impur-ting rotation to the table, und a plurality of circulurly arranged trays carried by the tuble in tilted relation thereto, said trays euch comprising: a bottom and two adjoiningr sides, ihc corner formed by the t'wo sides being; lowered and disposed townrd the center of the table.
In testimony whereof i have hereunto signed my nume to this specification in the presence of two subscribing witnesses.
