nary 14, 1920. Serial No. 351,366.

To all whom it may concern:

Be it known that I, HENRY A. vi lsn Noon,

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 Device for Delivering Stereotype Printing Plates and Tails from a Finishing Machine, of which the following is a specification.

This is a division of my Patent No. 1,341,608, granted on an application erial No. 726,239, originally filed Get. 1?, 1912.

This invention relates to the production of curved stereotype printing plates in condition ready to be applied to the press.

The principal objects of the invention are to provide a machine in which practically no hand labor will' be required in handling the severed tails which ordinarily are returned to' the melting '-pot, and also to provide means whereby the plates are retarded as they pass down an inclined runway and the tails cut off the plate in the finishing mechanism will be delivered by gravity and arranged by gravity in proper position to be taken up by a conveyor and delivered back to the melting pot, and other improvements in details of construction and combinations of parts as will appear hereinafter.

Reference is to be had to the accompanyingdrawings in which Fig. 1 is a front elevation of a machine constructed in accordance with this invention;

Fig. 11 is a side elevation of the parts shown in Fig. 10, and

Fig. 12 is a view of a portion'of'the machine looking down on the same normally to the path of the movement of the plate therethrough. i

In my Patent No. 1,269,239, granted June 11, 1918, I have shown a machine in which Specification of Letters Patent. Patented J n 6 1922 Original application filed October 17, 1912, Serial No. 728,239. Divided and this application filed Janthe finishing operationis performed in such a way that the plate is fed through the finishing means by the action of gravity, thus ellmlnating most of the labor of handling the plate during this operation without materially adding to the amount of power required for this purpose. The present invent on lnvolves the use of this principle, but 1n addition thereto the disposal of'the severed tails.

Referring first to Figs. 1 and 2, the machine is illustrated as supported by a framework A which is provided at a distance above the floor with a platform B for the operator which is reached by means of steps, or the like. On the frame are arranged in inclined position and substantially in alignment with. each other a casting mechanism C, and a finishing mechanism D. A cooling mechanism E is supported by the frame A also, at the end of the finishing mechanism. Atone side of the frame near the casting mechanism is a receiver for the severed tails shown in the form of a melting furnace F. Extending from the finishing mechanism to this furnace is an arrangement G for transferring the tails or risers removed from the plates to the furnace for remelting.

The furnace and casting mechanism are driven by a motor K. This motor through suitable gearing drives a shaft which in turn drives the stirrer of the melting pot, which forms a part of the furnace. The melting furnace, as usual, has a pump operated by a handle H.

It will be obvious that an inclined runway is provided parallel with the direction of the axis of the finishing mechanism; Therefore the plate is free to slide down the run way. For the purpose of retarding this motion and keeping the movement of the plate under the control of the operator, while moving into the finishing mechanism, a retarding means is provided comprising in this instance a pair 0f toothed wheels 80 in andjcooling stereotype printing plates No.

face thereof with a series of inserts 82 for.

affording africtionsurface. These preferably are formed of cork. Adapted to bear against the. faces of these wheels is a movable member 83 provided with similar i'nserts 82*. Two studs 84: on which the wheels are mo untedto rotate are provided on a bracket 81. The member 83 is pivoted to an arm of a lever 85 which is pivotally mounted on the bracket 81 on the frame of the machine. The other end of this lever is pivotally connected with an adjusting screw 86 which is tapped into the frame A. The screwis provided with a collar stud 87 for the reception of the end of the, lever and with a hand wheel 88 by which it is adjusted. In this way it will be seen that the friction can be adjusted readily, and although gravity is depended upon for con-' veying the plate down the-incline, the mo tion of the plate is entirely within the trol of the operator.

Theplate is fed down in this way under thefcontrol of the operator to the shaving arch of the finishing mechanism, D, and. while there the plate is clamped, rotated, andshaved inthe manner indicated in my Letters Patent on a Machine for finishing 1,238,978 dated Sept. 4, 1917, or in any other desired way.

tatable saw 90 which also is operated in accordance with the principle set forth inthe above identified patent or otherwise as may be desired.

The shaft 1 carrying the shaving knife 11 is provided with a tumbling pulley 2 mounted thereon and adapted to supportthe tail T as itis sawed from the main part of the plate. This pulley is of segmental form and r in which the plate P is being clamped in the shaving arch D by the meansshown in my above mentioned application, and the tail T is supported on a projection 7 formed eccentrically on the tumbling pulley for this purpose. One edge of the "plate rests on a guide 8 attached to the arch and the other rests on a pivoted receding track 9 as shown in my above identified patent. The shaving At this time also the tail is. cutoff the plate by means of a moving ro-.

shaft and the tumbling pulley are at rest in n this position of the parts. The driving pin 4 is engaged in the slot 5 at one end holding it from moving in the direction of the arrow in this figure. The rotary cutter 90 is indi-' cated in dotted lines. Now assuming the shaving shaft to rotate in the direction of the arrow (Fig. 7) it moves the pin to the other end of the slot, and therefore picks up the tumbling pulley after the shaft is The plate in the meantimehas' The next position of the parts is shown in Fig. 9 in which a projection 10 on the pulley engages the rear edge of the tail and acts to positively move it with the shaft. Fig. 10 indicates how the tail is dropped from the tumbling pulley after the saw has oompletely severed it. The tumbling pulley weight of thetail turns the loose pulley and brings the parts into the position shown in Fig. 10, the pin a coming then at the other end of the slot. Then the tail is free to fall away from the pulley by gravity and is de posited on the chute 91 concave side up;

When the tails are dropped in the chute 91 they descend through it into engagement with an inclined platform 92. It will be seen that they lie in the chute in a direction with their axes parallel with the general direction of motion of the plate through the casting mechanism. When they engage the platform 92 the weight of the tailsacted on by gravity causes the tails to be turned so that their axes are parallel with the direction of an endless conveyor 93. This conveyor is operated by a motor K and is provided with a series of projections 94 on 'the' chain thereof which engage the rear edges of the tails and convey them up the inclined conveyortrough 95to a platform 96 above the melting pot F from which they'can descend through a chute 97 into the melting pot. that plates to be remelted can be deposited on the conveyor by hand or otherwise and moved in the same way into the melting pot or otherreteiver for the metal. The stereotype plate disclosed isnotclaimed herein as it forms the subject matter of my codate herewith.

It will be understood also of course It will be understood, of course, in accordance with my above mentioned Patent 1,238,973, that while the tail is being cut from the plate the interior also has been shaved out by the shaving blade and the front edge trimmed up if desired. While these operations are performed the chips collect'on an inclined surface 12 and are stopped by a plate'l3 located at the bottom of the same to direct them into any convenient position. The plates being released then from the shaving arch by the operation'of the treadle I-I slide down the incline on a horizontal track 14 constituting the support for the plates of the cooling trough E.

Although I have illustrated and described the-machine in detail, I am aware of the fact that the principles herein involved can be carried out with other forms of mechanism, and especially other forms of finishing mechanism, without departing from the scope of the invention as expressed in the claims, and I am also aware that any mechanism shown herein which is similar to that described in my previous applications and patents above identified can also be changed within the scope of this patent. Therefore I do not wish to be limited in these respects, but
