Specification of Letters Patent.

Patented Jan. 7,1913.

Application filed April 23, 1897, Serial No. 633,518. Renewed January 6, 1906. Serial No. 294,923.

To all whom it may concern:

Be itknown that I, HENRY A. WISE Wool), a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvementin Sheet- Delivery Mechanism, of which the following is a specification.

The object of this; invention is to provide a new and improved sheet delivery mechanism, especially adapted for use in connection with cylinder printing machines, which shall be simple, of few parts,- and ellicient to accomplish the many functions herein after described.

To this end, my invention consists in arranging a delivery mechanism with a re ciprocating carriage, in mounting in said carriage a set of tapes, and in providing means for so controlling the tapes that the said tapes will advance or run to take the sheet thereon, will substantially stop as the carriage moves forward with the sheet, and will draw from under and thereby deliver the sheet as the carriage moves backward.

I further preferably so actuate the carriage that the same will have a dwell in one eX- treme position as the sheet runs on to the set of tapes. I also mount in the reciprocating carriage a fly which may be con nected or disconnected. \Vhen the fly is connected, the carriage is held stationary,

and the fly is arranged to coiiperate withthereby to the tapes in the carriage at theproper time. I also preferably arrange a slitter and a set of strippers in the carriage, so that when the carriage is moved to its extreme, away from the cylinder of the printing machine, said cylinder is very ac eessible for the .purpose of making ready. A form of preferred driving mechanism that I use to reciprocate the carriage is a crank mechanism provided with a relief to allow for the dwell heretofore mentioned.

The best understanding of the details of my invention will be had by referring to the accompanying four sheets of drawings forming part of this application, and which illustrate the best form now known to me for carrying out my invention.

Referring to said drawings and in detail, Figure'l is a rear elevation of a printing machine with my improvement applied thereto, Fig. 2 is a similar elevation from the other or front side of the machine, Fig. 3 is a sectional view illustrating part of the driving mechanism for the belt which drives the tapes in the carriage, Figs. 4 and 5 are detail views of a ratchet mechanism used between the driving belt and the set of tapes, Figs. 6 and 7 are detail views of the shaft which carries the fly and the forward tape-pulleys, Figs. 8 and 9 are detail views of the crank mechanism which is used to reciprocate the carriage, Fig. 9% is a detail view illustrating the action of the strippers mounted in the reciprocating carriage, and Figs. 10 to 13 inclusive are diagrammatic views illustrating the operation of my improved delivery mechanism.

In the drawings I have illustrated my invention as applied to act as a front delivery in connection with an ordinary two-revolution cylinder printingmachine, although it is to be understood that my delivery mechanism can be applied to any kind of printing press or other machine.

Referring to the drawings and in detail, A, A are the usual side-frames.

B designates the usual reciprocating bed, which is driven by any of the usual bed movements, not necessary. to show.

C designates the impression cylinder.

1* designates the feed-board of the machine, and T designates the receiving table, upon which the printed sheets are to be delivered.

The driving shaft of the machine 10 may be journaled in the frames in the usual manner, and may have mounted thereon any of the usual tight and loose pulleys or other power-imparting devices. Mountedon said shaft is a pinion 11, which, by means if intermediate l3 communicates motion to gear 14 mounted on the shaft 15 of the impression cylinder C, which shaft 15 is mounted in eccentric bushings 16 journaled in each frame, which bushings are oscillated by any of the usual mechanisms to raise and lower the impression cylinder at the proper time. The pinion 11 also meshes with a gear 17, turning with which is a pinion 18, which drives a shaft 19 by means of gear 20 mounted'thereon. Also mounted on the shaft 19 is'a gear 120, which, by means of intermediate 21, drives another shaft 22, by means of gear 23 mounted thereon, the shafts 19 and 22 in the particular instance illustrated making one turn for every two turns of the impression cylinder. Mounted on the front side of the shaft 19 is a cam 24. which bears -on a roller 25 mounted on a vibrating arm or lever 26, which is pivoted at 27 on the front side frame of the machine. A springpressed rod 28 connects to an arm projecting from said lever 26 so as 9 keep the roller 25 spring-pressed against the cam 24. At the upper end of this pivoted lever 26 is formed an internal segment 29, which, as hereafter described, is arranged to operate the fly. Arranged on the shaft 22 is a yoke 31, which. carries a roller 32, which engages the groove in a face-cam 30. Said yoke connects to a pivoted segment'33, which segment engages a pinion 34 secured on the 'end of a shaft 35 journaled in the side frame, as shown. On the outer end of this shaft 35 is secured a belt-wheel 36, which, as hereafter described, operates the driving belt for the set of tapes.

D, D represent two frames which constitute a carriage, and which frames are gibbed or fitted to slide on suitable ways 37 formed on or secured to the side-frames. Journaled in the side-frames D, D are two shafts-38 and 39, and suitable tie-rods as 4040 may be arranged between the two side-frames D, D, to tie the same together so that the entire carriage will move as one piece. Rigidly mounted on the shaft 38 is a'tape-roller or set of tape-pulleys 41, and loosely mounted on the shaft 39 are a number of tape-pul leys 42. Arranged between the tape-roller 41 and the tape-pulleys 42 is a set of tapes 43.

For some purposes, where it is not desired to use the fly, as hereinafter described, a wide belt or apron may be arranged between the two. shafts 38 and 39 in the usual manner, and such device is the equivalent of the set of tapes, as I use that term in the claims. Loosely mounted on one end of the shaft 38 is a pulley 44, around which is passed a driving-belt 45. Journaled on studs fitted in the rear frame D are pulleys 46 and 47. J ournaled on a stud secured to the rear side-frame A is a pulley 48, and

adjustably secured to the front of said side frame A is another pulley 49, which is mounted in an adjustable arm 50. The belt 45 passes around the pulley 47, then around the pulley 49, and is then wrapped around and secured to the driving-wheel36. The other end of the belt passes around the pulley 46, around the pulley 48, and has the end thereof also wrapped around and secured to said driving-wheel 36. The driving-wheel 36' preferably has two faces, as shown in Fig. 3, so that the two ends of the belt 45 can be nicely turned around the same in opposite directions, and secured to said driving pulley; The loosepulleys 46 and 47 are arranged so as to have their lowest point substantially in line with the top points of the I fixed pulleys 48 and 49. By this construction, asthe driving-wheel 36 is turned in one direction or the other, the belt 45 will be run in one direction or the other. Also by this construction, that portion of the belt extending from pulley 46 around pulley 44 back to pulley 47 may be said to constitute a traveling wave in said belt; that is, as the reciprocating carriage moves backward and forward, this wave of the belt will move backward and forward between the pulleys 48 and 49 without afi'ecting'the position of said belt on the driving-wheel 36, or without affecting the tension of the driving belt.

By this means, the shaft 38 can be controlled, as hereafter described.

In some instances, where the peculiar construction and arrangement of the tape-pulleys 42 and fiy-fingers hereafter described is not .used, the belt 45 maybe carried around a driving pulley mounted on the shaft which carries the forward tape-pulleys. The tension of the belt can be adjusted by the adjustable pulley 49. The pulley 44 is so arranged on the shaft 38 that only a movement in one direction of the belt 45 will be transmitted'to the shaft 38; that is, the pulley 44 is loosely mounted on the shaft 38 between the frame D and a ratchet-wheel 51, which is rigidly secured upon said shaft 38. A pawl 52 is pivoted to said pulley 44, and is pressed into engagement with the ratchet-wheel 51 by means of spring 53. By this arrange ment, only the motion of the pulley 44 in Fig. 4, corresponding to the movement of the hands of a'watch, will be imparted to the shaft 38. The movement of the pulley 44 'in the opposite direction will simply cause the pawl 52 to travel backward around the ratchet-wheel 51. I preferably provide another-ratchet-wheel 54 on the inside and on the shaft 38, next to said frame D, and I arrange a pawl/55 on the frame D, with a spring 56, which pawl is adapted to prevent the shaft 38 turning backward! when the pawl 52 travels around its ratchet-Wheel.

By this-arrangement, when'the driving-belt 45 is moved in one direction, the shaft 38 shaft 57, on which is mounted an adjustable arm 59, which carries a slitter 58, which may be set in the proper position to cooperate with the tape-roller 41. Also journaled in said frames D, D is a shaft 60,.which carries a set of stripper-fingers 61, which are laterally so arranged as to fit in between the grippers c in the impression cylinder C, as indicated in Fig. Said stripper-fingers may be held normally in one position by means of a spring 62, and may be operated by any suitable means from the impression cylinder, as by means of an arm 63 mounted on the shaft 60, which is fitted to engage a pin or cam 64 mounted on the front face of the impression cylinder C.

By mounting the slit-ter 5S and the strippers 61 in the traveling carriage, it will be seen that very free access is given to the front of the impression, cylinder, for the purpose of making ready, as indicated in Fig. 11. On the front end of the shaft 22 is arranged a crank-arm 65, loosely pivoted in the end of which ,is an eye bolt or crank-pin 66, loosely fitted in which is a pit-man 68, the lower end of which is screw-threaded, and which has nuts 67 mounted thereon. The pitman 68eonnects by bolt 69 to a yoke 70, which is fitted to slide on the shaft 22. The upper end of the yoke 70 has rack-teeth 71, and the same fits into a frame 170 pivoted on a shaft 73, which shaft 73 is journale'd in the side-frames A, A. Secured upon the shaft 73 is a pinion 72, which engages the rack-teeth 71. Fitted on the ends of the shaft 7 3 are gears 74, which engage with and drive racks 75 secured to the lower sides of each of the frames D, D. By this mechanism, the traveling carriage will be reciprocated.

"Screws are tapped through lugs 81 secured to each side-frame, as shown, to limit and adjust the movement of the frames D, D toward the impression cylinder. The movement thus imparted to the traveling carriage is substantially crank-actylated, except that the peculiar arrangement of the crank with the relief, as before described, allows the carriage to dwell in its position nearest the impression cylinder; that is, as the carriage moves to the right, Fig. 2 the yoke 70 will strike will come against the adjusting screws 80, when the crank is substantially in the position indicated by thedotted line a in Fig. 8. Then, as the crank moves from this position, to the position indicated by dotted lines 6, the eye bolt will run down and up on the pitman 68, without imparting any movement to the rod 70, so that, during the time of the crank between the dotted lines a and b, the carriage willrdwell in its extreme right-hand position. v

After the crank passes the dotted line b, the eye bolt 66 will push up on the adjuston the shaft 22, or the frames D, D

able nuts 67, and between the dotted lines.

6 and a, the rod 70 will be pushed up and down, a spring 700 being arranged between the bolt 69 and the shaft 22 or a stationary point, to keep the nuts 67- in engagement with the eye bolt 66. By adjusting the nuts 67, the time of the dwell of the carriage can be adjusted. By disconnecting the nut on the end of the bolt 69, the pitman 68 can be removed, and withdrawn from the eye bolt, and the crank 65 thus rendered inoperative, and thereby the carriage can be held in its extreme position nearest the impression cylinder, so that the sheets can be delivered by the fly, as hereafter described. While I prefer to use this crank mechanism provided With a relief, of course a cam could be arranged on the end of the shaft 22, to accomplish the same purpose.

Keyed or otherwise fitted on the frontend of the shaft 39 is a pinion 76, which, when drawn to its outer-most position, as shown inF-ig. 6,. will engage with the segment 29, but which, when pushed in near to the sideframe D, as indicated in Fig. 7 will clear the said segment. A catch 77 is provided on top of the frame D, so that, when the pinion 76 is pushed in, as shown in Fig. 7, the same will be held in its innermost position, and the shaft 39 from turning, so that the pulleys 42 can nicely turn on the shaft. Arranged on the shaft 39, between the tape-pulleys 42, are a set of flyfingers P, P, which intermesh with the tapepulleys 42, as indicated in Fig. 6. When the pinion 76 is pulled out to engage the segment 29,.the shaft 39 will be oscillated, so that the fly-fingers will be swun around on an arc to take the sheet up rom the tapes 43, and deliver the same. When the pinion 7 6 is disconnected from its segment, the fly-fingers will remain down in an inoperative position, below the tapes. As the tape-pulleys 42 are loosely fitted on the shaft 39, so that they can freely turn thereon, this arrangement enables me to greatly simplify the parts.

Referring now to the diagram, I will explain the operation of my device.

In Fig. 10, the carriage is shown as dwelling in its left-hand extreme position. The driving-wheel 36 is turning in the direction indicated by the arrow, and therefore the belt 45 is running in the direction indicated by the arrows, turning the pulley 44, thereby the shaft 38, and thereby the tapes 43 so that the sheet S is being carried from the impression cylinder down on to said tapes, the cam 30 being properly proportioned to nicely accomplish this result. So. soon as the sheet is nicely on the tapes 43, the belt 45 stops running in the direction before indicated. Then the carriage moves" forward, the tapes being held stationary, and, by this movement, the sheet is nicely carried position to the movementof the'hands of awatch, and therefore, do not afi'ect the shaft 38 or the tapes 43. 7 After the carriage has reached its extreme position to the right, the same starts backward toward the impression cylinder. During this backward movement of the carriage, the driving belt 45 is held stationary. Thus, as the carriage movestoward the cylinder, the driving belt 45 will run around the pulley 44 in the same direction as the hands of a watch move, and exactly at the same time and speed at which the carriage moves backward. This will cause the lower portion of the tapes 43 to withdraw from under the sheet, and the upper portion of the tapes 43 to stand stationary relatively to a fixed point, so that the tapes will be bodily withdrawn from under the sheet, and the sheet nicely deposited upon the delivery table T, as the pulley 44 is substantially the same diameter as the tape-pulleys or roller 41. When the carriage reaches its left-hand extreme, the stripper fingers 61 actuate to start a second sheet down'on the tapes 43, and the action before described is repeated.

The mechanism before described for reciprocating the carriage is a desirable one, in that it starts the carriage quickly on its forward movement after the sheet has run thereon, brings the same to an easystop in the extreme right-hand position, and starts slowly backward; in otherwords, imparts a crank reverse to the carriage. at its righthand extreme.

In Fig. 13 I have indicated how my device is used when it is desired to fly the sheets instead of delivering the same b .the tapes. In this arrangement, the pitman 8 is disconnected, as before described, so that the carriage remains all the time in its position next the impression cylinder; The pinion 76 is slid out to engage the segment 29. The tapes are left to run, as before described. Then, when a sheet has been run down on said tapes, the fly picks the same up off the tapes, and turns the same over, and delivers the same on the table T.

By the constructions thus described, a very simple and complete delivery mechanism is provided, which can be used to deliver the sheet in a variety of manners, as before de scribed.

The details and gearing and relative arrangements of the parts may be drawn out,

proportioned and designed by a skilled mechanic in very many .ways, without varying from the principles of my invention, as

herein claimed.
