SHEET-DELIVERY FEED.

Original application filed June 13, 1912,

To all whom it may concern:

Be it known that we, ISAAC J. IVrrrrAM and GEORGE S. WITHAM, Sn, citizens of the United States, residing at Hudson Falls, New York, have invented certain new and useful Improvements in Sheet- Delivery Feed, of which the following is a clear, full, and exact description.

This invention relates to a delivery device and is a division ofour co-pending application for improvements in sheet deliveryapdevice or cutter which severe; the end of the Web to form a blank, and this blank, is then advanced by the delivery device.

The machine to which the delivery device delivers the blanks in the present instance comprises in its construction a rotary table carrying a number of dies which are presented successively before the delivery device, and at the moment-that each pair of dies is presented the delivery device projects one of the blanks into position between the dies.

One of the objects of the present invention is to provide a delivery device of very simple construction and which will be eflicient in operation.

One of the many further objects of the invention is to construct the delivery device so as to render it completely under the control of the operator atall times, and especially to enable the operator to control the time at which the blank is projected into the finishing machine.

The invention further consists in the general combination of parts and simplicity of details hereinafter described, all of which contribute to produce an efficient feeding machine. 7

1 is a side elevation of a feeding machine to which our delivery device is applied; Fig. 2 is a plan of the machine shown in Fig. 1; Fig. 3 is a cr'oss'section through the machine and particularly illustrating the arrangement of thesevering device; Fig. 4: is a longitudinal section taken through the upper part of the deliverydevice and showing its preferred construction; and Fig. 5 is a plan and partial section illustrating means for varying the speed of operation of the delivery device.

Referring more particularly to the parts, 1 represents the frame of in which the stock may be carried in two rolls 3, the webs 4 from which may be guided across a suitable horizontal table 5 so as to pass through feeding devices 6 and 7 before reaching the severing device 8. The feeding devices 6 and 7 may be in the form of rolls 6 and 7 between which the web passes, and these rolls may be rotated continuously'by suitable gearing 9 which mayv be driven by asprocket chain 10 'in any suitable manner. The table 5 presents'a trans verse edge 11 beyond the feed device 7 at which the web may be out into blanks by the severing device 8. This severing device preferably consists of a knife or cutter 14 which is fixed to a gear 12 mounted to rotate on a horizontal axis-atthe side of the machine and in such a way that the knife 14 rotates in a plane transverse to the path of the web. The gear 12 may be in the form of a bevel gear driven by corresponding bevel gear 13. The direction of rotation is such that the knife passes down across the edge 11. The path of movement of the knife guard 15 to prevent injury to persons standing near the machine. Beyond the severing device 8 our improved delivery device 16 is placed. 'This delivery device is preferably constructed in such away that when the loose end of the web is advanced beyond the cutter, the delivery device receives it and may exert a yielding pull upon it so that as soon as the blank is severed it is rapidly withdrawn. In Fig. 2 the dotted line 17 indicates the extremity of the loose end of theweb which has been advanced beyond the cutter.

The delivery devic e 1 6 preferably comprises a pair of receiving rollers 18 and a feeding machine as it moves upwardly is partially covered by a pair of delivery rollers 19 preferably arranged as indicated in Fig. 4. The upper roller 18 is connected with the upper roller 19 by endless belts 20, and similar belts 21 connect the lower pair of rollers. The faces of the rollers 19 are near together while the rollers 18 are disposed slightly apart so that the adjacent runs 22 of the belts diverge in the direction of the rollers 18 in such a way that a receiving opening or throat 23 is formed between the rollers and between the belts which receive the loose end 24 of the web as it advances. WVhen the machine is in operation, the runs 22 of the belts move in the direction of the arrows as shown in Fig. 4, and the belts contact with the end of the web and tend to advance it by reason of the frictional force which they exert by their movement in the direction of the arrows. When a sufiicient quantity of the web has been advanced past the severing device 8 to form a blank, the cutter or knife 14 passes the edge 11 and severs the blank from the web. The instant that this blank is severed, the delivery device 16 advances it between the rollers 19 and delivers it to the second machine, that is, into the machine which may form the finished article from the blank. As the cutter 1& moves at a very high speed, the advance of the web may be continuous. The

belts

20 and 21 are preferably driven independently and at a hlgher speed than the web advances so as to insure that the blank which has just been severed will pass out of the delivery device before the end of the web advances into it to form the next blank. In order to accomplish this, the shaft 25 of the lowerroller 19 is driven at an increased speed by a belt 26 running over a pulley 27 on a counter-shaft 28, said counter-shaft being driven by a belt 30 running over a pulley 29 and said belt 30 being driven from a shaft 31. From this shaft 31 the gearing 9 which drives the feeding devlces 6 and 7 is driven through the aforesaid sprocket chain 10. The shaft 31 may be driven 'from the machine which receives the blanks from the delivery device. This may be accomplished by means of a large gear wheel 32 rotating with the receiving machlne and driving a vertical shaft 33 through a pinion 34, and this shaft 33 drives the shaft 31 through gears 35 from shaft 36. Shaft 36 may be driven directly from shaft 33 by bevel gears 37.

The operation of the feeding device '6 may be controlled by means of a lever 38.

It is desirable to vary the speed of the

belts

20 and 21 when desired, because the blanks must be projected between the dies of the forming machine just at the proper instant and at the instant that they are presented to the delivery device. Of course by varying the speed of the

belts

20 and 21 the periodic delivery of the blanks is controlled. If

the part carrying the dies of-the finishing or forming machine tends to a condition or phase so that the normal moment at which the blank is projected would'be too early or too late to catch the receiving dies in the proper position, then the operator adjusts the speed of the

belts

20 and 21 so as to throw the blank earlier or later. For this purpose we provide a speed controlling device which may have the form illustrated in Fig. 5, that is, the pulley 29 is preferably in the form of a cone-pulley and cone-pulley 29 on shaft 31 which cotiperates with it, drives this cone-pulley through the aforesaid belt 30.. By shifting the belt 30 on these cone-pulleys the driven speed of the delivery device may evidently be controlled. In order to shift the belt 30 we may provide a belt-shifter 39 mounted on the feed-screw 40 rotated by a suitable crank 41. This belt-shifter 39 -may be guided on a transverse guide-shaft 42. When the feed-screw 40 rotates in one direction, the belt-shifter and belt 30 are moved one way and when rotated in the opposite direction they are shifted in the other direction, that is, a part of the belt-shifter 39 forms a nut on the threads of the feed-screw 40. a

The delivery device described above is the preferred embodiment of our invention, but it is understood that this is one of the many forms the invention may take; therefore we do not wish to be limited in the use of the invention nor in the claims to the particular embodiment described above.
