PILIIll'G-TABLE FOB PRINTING-PRESSES.

I" v i cide t-pee,

To all who 1n it may concern lie it known that l, ltonrn'r MIEHLE, a citizen oi the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Piling-Table for Printing-Presses, of Which the following is a specification.

This invention relates {to-piling tables for receiving the sheets from a sheet delivery of a printing press, or other machine, and it has more especial reference todcvices of this nature for use in conjunction with that form of printing press in which the ink fountain and apparatus is arranged at one extremity of the stroke of the bed, and Which, as heretofore constructed, is usually situated directly under the piling table, or other sheet-receiving surface This relative location'o-f tlie' pi'ling table and'ink fountain is found very objectionable, in that the ink fountain and apparatus is not readily accessibl'e during. the operation of the press, atod even-at other times is awkward of management, and requires the table to be moved; and furthermore, What is probably a more serious objection, is, that it very materially curtails the range of vertical movement of the piling table, rendering it incapable of being started at a high elevationand lowered close to the floor while receiving sheets.

One of the important objects of this invention, therefore, is to provide for a Wide range. of vertical movement of the piling table, or sheet receiving surface, which is accomplished by arranging the actuating shaft of'the adjusting mechanism of the re ceiving, surfacein sucha position Withre spect to the surface that it will not projectover the edge of the surface into the path of the upward or -downward movements thereof, and so that the shaft will be located to one side of the surface and else; of the pile of sheets on the receiving surface; a;

further object being to afi'ord this Wide range of movement of the piling table whilerendering it possible to connectdt with a press for automatic operation thereby-f f With a view to the attainment of 'these ends, and the accomplishment ofcertain other Specification of Letters latcnt.

rangement of parts, which Will now be descrlbed With. reference to the accompanying drawings, and more particularly pointed out in the claims.

In said drawings-Figure 1 is a side elevation of my improved printing press. B 1g. has an enlarged detail view hereinafter descrihed Fig. 3 is a side elevation of the press looking from the opposite side to that presented in Fig. 1. And Fig. lis a plan view thereof.

The printing press proper is of a well known type of flat bed press comprising. among the usual features of mechanism, an ink fountain or apparatus A,arranged at one end of the stroke of the bed, and supported in the usual manner upon the main frame 1, at the opposite end of which is journaled the usualimpression" cylinder B. This ink fountain or apparatus in presses of this character has heretofore been mounted under the sheet piling table, downwardly toward which the sheet-conveying tapes 2 con duct the sheet to a positionover the sheet delivery, which may he of the well'known fly-finger type or reciprocating carrier.

The piling table constructed in accordance with the present invention is adapted for use with conveyor tapes ,2 which are supported at an elevated position b an upvvardly extending frame 3,. high a (We the mk fountain A, so. as to deliver the sheets to 'the supporting surfacefrom overhead, and the piling table C is set-0d from the ink fountain A at a considerable distance therefrom so as to form" a passage-Way D be tween the table or. other sheet receiving surface and such fountain, whereby theerable elevation in a suitable frame 4, which also servcsas a means for supporting the ways or traclrst, 6, for the sheet pJl'IlGI carriages 7, 8, at one end, while the opposite ends ofv these ways 5, dare-supported by extensions 9, 10, of the frame 3. The sheet delivery mechanism itself may be of the tion and operatl a of any details of the de' livery not herein illustrated, and also shown in my U. S. Patent #909,199, issued January 12th, 1999. The carriages 7, 8, constituting a portion of the reciprocating sheet partner, are given their necessary reciprocating travel on the ways 5, 6, but suitable operative connections extending across the passage-way D to the operating mechanism of the press proper, and these connections, as also the connections for operating the fly fingers to be presently described, instead of being carried across the passage-way D near the floor line, which would bring them in the way of the feet of the attendant, are preferably carried across at an elevation high above the ink fountain or mechanism. With this arrangement it will be apparent that the actuating shaft of the table will be located to one side of the sheet receiving surface so that no portion of such shaft will project over the edge of the table or surface into the path of the adjustment of the table upwardly or downwardly. The reciprocating sheet delivery mechanism is operated by two links 19, 20, which are respectively connected with vibratoryarms or levers 21, 22, se: cured to a rocker shaft 23, which latter is journaled in the frame extensions 9, 10, ,and to one side of the piling table or surface, and this shaft is rocked by an arm 24, as shown and described in my aforesaid patents. .The shaft 23 is rocked from a crank 28 on the shaft 29 through the medium of the rod 27, lever-26 and rod 25, and the fly operating cam 30 is also actuated by the shaft 29, and these parts are adapted to be rendered inactive in the manner set forth in the last recited patent. The rocker shaft 16 is actu atcd by the shaft 33 to which latter it is connected by the usual pinion or toothed segment 34 engaging with a raclrba'r 35 arranged above it on the end of a connecting rod 36 extending to another pinion or toothed segment 37 secured to the rocker shaft 16 and engaging a rack-bar 38 secured to or formed on the outer end of'rod 36, the two rack-bars 35, 38, being arranged to slide in suitable keepers 39, 40, pivoted around the centers of shafts 16, 33, respectively, similar to the keeper 23 shown and described in my aforesaid patent. Thus itwill be seen that when the shaft 33 is oscillated,'similar oscillation will be imparted to the rocker shaft 16, and consequently the fly fingers 15 will be moved back and forth, resting below the tapes 2, until the sheet arrives at the limit of its travel on said tapes, and then rising noeaeaa between the tapes in the usual way for flying the sheet and delivering it upon the piling table.

The pinion or segment 32 on the shaft 33, which latter in my former patent aforesaid served as a means of supporting and oscillating the fly fingers, derives oscillation or back and forth rotation in the usual way from cam 30, that is to say, by a lever 41 pivoted to frame 1 and carrying an antifriction roller 42 adapted to be held in contact with the periphery of cam 30 by a spring 43 on a connecting rod 44 pivoted at one end to lever 41 and having its other end pro vided with the usual rack-bar 45 sliding in the usual keeper 46and engaging pinion 32. When the reciprocating carrier is to be used, the lever 41 is held out of action by any suitable stop 47.

48 is the usual springactuated rod connected by a crank 49 to fly finger shaft 16 for assisting in throwing the fly toward the table, as well understood, the rod being supported in this instance on the side of frame 4 in an upright position in suitable guides 50, 51.

By thus locating "the piling table C at a distance from the inkingapparatus, I not only provide a passage-way between it and the inking apparatus, but I very materially increase the receiving capacity of the table, and am enabled to make the table vertically adjustable throughout a wide range ofmove mentabove the fioor, which adjustment will not be interfered with by the projection of any portion of the actuating shaft pr0jecting into the path of the adjustment of the table or receiving surface; To this end, therefore, the table is supported at both.

sides by vertical screws 52, 53, jouinaled in the frame 4 and having threaded connection with-the table, so that when the screws are rotated the table will descend or ascend according to the direction of rotation. The upper ends of these screws 52, 53, are connected together by a counter-shaft 54 journaled across the inner side of the frame 4, and to one side of the table and which countershaft has at its ends two sprocket wheels 55, 56, which are connected respectively by chains 57, 58, with sprocket wheels 59, 60, on stud shafts 61, 62, journaled in suitable brackets 63, 64, on top of frame 4, and having bevel gear connection 65, 66, respectively, with the upper ends of screws 52, 53, so that the screws will be driven in unison when the shaft 54 is rotated. The shaft 54 is thus rotated automatically by any suitable connection with the sheet delivery m'chanism. This connection for the reciprocating form of delivery comprises a long pawl 67 pivoted to rocker arm 24 and arranged to engage a ratchet wheel 68 secured to shaft 54, each time the rocker arm makes a backoeaeaa ,proximately a distance equal to the thickness of a single sheet of paper, or equal to the thickness of a plurality of sheets if a plurality be delivered upon the table atone time, the extent of the effective action of the pawl 67 being regulated by a deflecting cam 69 adjustably secured at 70 to the side of frame 4 and serving to hold the point of the pawl out of engagement with the ratchet wheel throughout a greater or less extent of its stroke. The, means for rotating the ratchet by the action of the fly fingers is shown in Fig. 2, and consists of a pawl 71 pivoted detachably to a short crank arm 7 2- secured on the end of fly finger rocker shaft 16, and capable of being thrownback out of the way or removed when the reciprocating delivery is to be used.

The table may be raised or lowered rapidly by hand when desired, through the agency of a crank 73 secured to shaft 54. By thus connecting the vertical screws of the table mechanism to a countershaft located at any point out of the range of both the table itself and the fly, it will be seen thatl am enabled to impart movement to the table automatically without interfering in any way with the movement of the delivery or curtailing the range of movement of the table, or interfering with the introduction of a truck under the table for allowing the latter to be loaded directly onto it in case it should be desired to do so.
