with said conveyor belts, drying said sheets as they are passing over said conveyor belts,

and, nearthe-point Where they are to be delivered, giving to said sheets an accelerated motionin' order togive to said sheets an 1m- 1 petus so thatth'ey will quickly fallin position at the point of delivery, say the yogger box. The conveyor belts are made of metal to keep the heatfrom injuring them, and for the purpose of keeping same in a normal condition at-all times.

The operation above described is used 111 connection with printed sheets which have a margin on each side thereof. \Vhen no mar-- gin ispresent on the printed sheets, andes- I pec ially whenthey are heavily printed, I employ a star wheelmechzinismyhaving small points which assist in feeding the printed sheets, at the point where the accelerated motion is desired-,the points being so small that none or very little impression will be made upon the inked sheet, as to disfigure or smear the same.

The-advantages and features of my invention will readily become apparent from readingthe following specification.

It will be understood that my device obviates the necessity of racking" the paper or slip-sheeting the same.

In the accompanying drawing, forming:

' a; part of this specification Fig. 2, is-a side view thereof,

Fig. 7 is a detail plan view of oneform of'the chains or conveyor belts used, Fig.8, is a side view of Fig. 7,

Fig. 9, is aviewin detail of the star wheel, l I

journaled in oneend-of the links- 3 1, the

and

the shaft 5.

. Fig-1, isa plan view of theattachmentj Fig. 10, is a central section through Fig. 9.

The attachment is used as before stated, in connection wlth printing presses and carries off the printed sheet to a delivery point; the

printing press not being shown, except the drive wheel 1, mounted on a shaft 2 of the sald printing press. A belt?) leads from pulley 1 tothe large pulley 1, mountedon a stud shaft 5, which is mounted in a frame made upof sides 6 and7, and stay bars 8.

At the front of the attachment, mounted in frames 6 and 7, I provide a pulley shaft Stand at the rear a pulley shaft 1O.

Securely mounted to these

shafts

9 and 10 are the sprocket wheels 12; thesesprocket wheels engage with the sprocket chains (conveyor chains) 13, which pass over the said sprocket wheels 12.

The pulley shaft 10 is revolved by means of the belt pulley 14- which is securely mounted thereon, a belt 15 passing over pulley 14,

and adjustable pulley 16, which pulley is mounted on a shaft 17,1nounted inside frameG. A'belt 18 also'passes over the ad- Justable cone pulley-16 and another cone pulley 19; this cone pulley 19v ismounted on It willbe seen that when the belt 3 is put into operation by the pulley 1, the

pulleys

4 and 19 being integral, will operate the belt 18, which in turn operates the belt 15 through medium of pulley 16, the belt 15 then revolving the pulley 1 1, which ais securely mounted to the shaft 10, will in turn revolve said shaft, causing the conveyor chains 13 to operate over the sprocket wheels 12-. 1 By this means the conveyor belts are operated and forced to travel-likean endless belt, carrying the printed sheets, which are deposited upon them, to their destination. 7 j

On the shaft 5, I mounta pulley 20 over which passes a belt 21, which belt also passes over the pulley 22, which is-securely mounted on a shaft 23. This shaft has its hearings inthe side extending arms21 which are fastened atthepoints' 25 to the side frames 6 and 7.

'Acljus-tablymounted on shaft 23 are the

feedrolls

26, 27, 28, 29 and 30. The feed rolls 26 and30 engage with

upperfeed rolls

31 and 32 which impart motion through 7 frictionalcontact. These rolls 31 and-32' are adjustablymountedon'a-shaft 38, which is other ends of said links being adj ustably mounted on the shaft 35; this shaft is mounted in the bearing plates 36 which are secured to the side extending arms 2i (see particularly Figs. 1 and 2).

iiil'iustably mounted on the shaft- 33, I provide the star teed wheels 2-37. This ad justinent or a lateral nature in order to cover various widths of printed sheets. The links ill being pivotally mounted on the shat. allows an up and down motion to accommodate the thickness oi the paper. in order to adjust the links 3-; laterally, 1 provide an adjusting clamp :38 and thuml'i screw Iii). liy operating screw 39 the clamp can be loosened or lightened and the links Iii can thus be moved to any position de sired and held there by reason oi slot. .10 in the clamp.

lit the star wheels 3? are not needed, they may be moved over out of the way by removing them from the attachment and when needed again they can be put back into position on account of their iuljustability on shaft 53.

in the tie bars 8, brackets 41, which are guides the guides being l'ormed angular in shape and have :lorwardly extending lingers all; to guide the paper to its limit of travel, at which time the sheets tail on the table it in the jogger box 15.

The lower tteed roll 52C) engages the roll 3 and the roll engages the roll 32, the

rolls

26 and 30 being the drivers and the

rolls

31 and 32 being driven.

1' provide a number of heaters, in the present instance, two are shown. In the present instance they are made up of a. tube section of pipe 46, provided with a multilicit v ot holes i? and are mounted in the side frames (3 and 7. 1i? I. desire to heat by electricity 1 use an electrical heating unit 4-8, shown in Figs. 5 and (S. The sheets of paper (printed) are dried as they pass over the healing devices.

The star wheels 37 are formed of a disc part i9 and have a hub secured to the shal'i 33 by set screws 51, and have at their periphery a large number of thin teeth 52, the teeth being formed or a knife-like edge, see Fig. 10, being, however, not pointed but slightly flattened on their edge. Two wings or brackets as 53 are shown for securing the attachment to the printing press.

In order to operate on margin, the rolls ill. and 232 are brought into contact with the drive rolls 2'7 and 12%.) see Fig. el, these rolls having a flat sur'taee :lace can be used when the delivery is made on the margin, the .roll Elli merely acting as a sup 'iorting roll. The

rolls

31 and 32 travel on the margin, but when no margin is present, then the star wheels Eli are brought into play, and they teed the sheets by contact with the prints 52.

l: mount adjustable :lasiened to the side The star wheels 37 are preferably adjusted to the inside of the lower rolls 27 and .29, which allows the paper to buckle or wave as the star wheel teeth pass down wardly and draw the paper over the lower rolls, see Fig. 3.

The printed sheet is marked 60, and in Fig. -i, it is shown marginally fed, and in Fig. 3, where no margin is present said sheet (50 is being ted by the star wheels 37 and i! will be seen in this figure that the printed sheet (it) is somewhat waved or buckled, as hereioikue stated, to give a proper contact for the star wheels with the printed sheets.

ilhrough the system cl? cone pulleys, belts, and different diameter ol? pulleys, 1 am enabled to operate the conveyor chain at any speed required, and to increase or diminish the same according to the size of the sheet which being printed, and through this nuans l am a lro enabled to speed the shaft which carries the feed rolls and the star wheels to a greater or less extent, and to operate the same taster than the sheets are conveyed in order to quickly precipitate said sheets into the jogger box or other suitable point of delivery.

The printing press to which this attachment is preferably applied, is, as before stated, one which has a constantly operating shatt :2 with a pulley 1. thereon, as this shaft and pulley continue to operate when this prii'iting press automatically steps or is manually stopped until all the sheets which have been printed, before stop nige, will be delivered properly, thus preventing the waste of any of the printed matter and preventing the same from taking fire by reason of any stoppage of the conveyors, thus saving the printed sheets and preventing loss.

If this attachment is attached to a printing press of another character, I may use a sn'iall motor to run and operate the same, and then continue to operate the same after the printing press has stopped, or, it desired, during the operation of the press, just as I see fit.

Vi hen the attachment is operated separately and independently of the printing press, or operated ten'iporarily when the printing press for any reason stops, I provide a motor as shown in Fig. 2.

The construction and term herein shown is a preferred way of making my attachment, but I may deviate therefrom and have the construction to some extent and may also alter the same without departing from the principle of the invention, when attached to a printing press of a different construction than the one to which it may be applied.
