SHEET-DELIVERY MECHANISM.

Specification of Letters Patent.

Patented July 26, 191th.

Application filed. February 28, 1906. Serial No. 303,359.

To all whom it may concern:

Be it known that l, EDMUND W. DEAN, residing at Dover, in the county of Strafl'ord and State of New Hampshire, have invented certain new and useful Improvements in Sheet-Delivery Mechanism, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to the handling by machinery of sheets of paper and the like, and with regard to the more specific features thereof to the accumulation and de livery of sheets from printing machinery.

One of the objects is to provide simple and eliicient means of the above general type.

Another object is to provide practical and positively-acting means of the above type adapted for efiicient use at the highest speeds.

Another object is to provide means of the type last-mentioned of simple, compact and inexpensive construction.

Other objects will be in partobvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the embodiment thereof hereinafter described, the scope of the ap lication of which will be indicated in the fbllowing claims.

The accompanying drawing is a diagrammatic view of-one of various possible embodiments of my invention.

In order that this invention may be readily and completely grasped it may here be noted that in connection with printing or other sheet-handling machinery, and particularly printing machinery adapted for use in conjunction with small sheets, it is essential on account of the considerable cost the other of which rests idly upon the web and holds it in operative relation to that first-mentioned.

The web is received from the cutting apparatus by a sheet-path, comprising tapes 7 and 8, driven in any desired manner as by the gearing diagrammatically mdicated at 8: It may be noted that these tapes converge in a direction away from the cutting mechanism, thus forming a bell-mouthed path, and that the upper tape 7 extends beyond the tape 8, as clearly shown in the drawing. The last-mentioned tape, moreover, is held by its guide-pulley in such position as to throw the upper tape slightly out of alinement, as shown at 9, for a purpose hereinafter described.

The sheets are thrown downwardly from tlfe sheet-path by swinging members or fingers l0, and rest upon a support or table 11 as shown at 12, being guided into exactly superimposed relation as by a series of stationary guides Y13 and swinging guides 14-. The latter parts are pivoted as at 15 and are adapted to swing laterally to permit the removal of the accumulated sheets 12 in the i3 manner hereinafter described.

Projecting through the table 11 are a series of fingers or abut-ments 16 mounted upon the shaft or spindle 17, which is connected as the link 18 with a lever 19 pivoted at 20. The latter member is swung in the direction indicated by the arrow by a spring 21, mounted upcn the rod 22 pivoted to the lever and compressed between same and an abutment 23. This spring is alternately compressed and released as by a snail cam 24, driven through suitable gearing, diagrammatically indicated at 24 from a shaft 25, rotated as by a ratchet 26 and pawl 27 in accordance with the movement of the fingers 10. It will thus be seen that as the latter members oscillate about the shaft 28, the cam 24 is turned through a predetermined fraction of a revolution with each oscillation, and, upon a predetermined number of sheets being thrown upon the table, the cam reaches such position as to release the roller 29 upon the lever 19 and to permit the above described parts to throw the abutments 16 in a direction to remove the sheets 12 from the table and place them upon a support 30. Upon this action taking place, the guide 14 merely swings so as to permit the passage of the sheets and automatically falls into the depending position shown, an anti-friction roller 31 being journaled in its lower end in order to avoid interference with the passage of the sheets.

Upon the abutments 16 being retracted, it is of course desirable that the same be depressed so as to avoid interference with the sheets which accumulate upon the table during this action. This is preferably brought about by a slide 32, which during the operative movement of the abutments 16 engages the lower edge of the table or other cam or guide surface, being held in position by a spring 33 mounted upon a rod 34 pivoted to the link 18 and slightly compressed between same and abutment 35 upon the lever 19. Upon the lever reaching its extreme position in the direction indicated by the arrow, however, the spring 33 is outof engagement with the abutment 35, as shown at 36, and permits the slide or block 32 to fall into a position below a guide 37.

The swinging members 10 may be actuated in any desired manner as by a cam 38 driven as indicated by the arrow and coacting with an arm 39 attixed to the shaft upon which the parts 10 are mounted. There is also provided a retracting spring 40 adapted to hold the ratchet arm against a stop 41, and thus normally maintain the parts 10 in proper raised position. At each rotation of the cam 38, however, the arm 39 is raised, thus swinging downwardly the members 10, which are quickly snapped into raised position again by spring 40 upon arm 39 being released. It is to be understood that this mechanism is merely diagrammatic and illustrative of the various t pes which might be employed, and it may e noted that the entire illustration of this invention is of a diagrammatic character, the frame work of the machine and various supports and bearings being omitted in order to avoid encumbering the drawings with irrelevant and immaterial matter.

It may here be noted that the term tapes is used throughout this description and the following claims in the broadest sense, as 'the specific members commonly known b this expression are in this case merely il ustrative of a large class of equivalents. It may also be noted that by the term curl is meant any bending or distor- 55 tion-of the sheet-or web.

eeas'rs The operation of the above-described embodiment of my invention is as follows Assuming the web to be fed as by the rolls 5 and 6, the same passes beyond the blade or abutment 3 and within the bite of the sheet path. The tapes of the latter apparatus are driven at a higher speed than that of the feeding rolls, and, hence, imme diately upon engaging the advancing free end of the web, put the same under tension. While in this condition, the cutting-blade 2 severs the web and the freed sheet immedi ately travels forward at a higher rate of speed within the sheet-path. On account of the disposition of the tapes of this path, the free edge of the sheet or web is slightly curled or inclined toward the tapes 7, thus causing the same to hug these upper tapes even though driven at a high rate of speed. It will thus be seen that the severed sheets are properly spaced upon arriving at the farther end of the path, inasmuch as, on account of the relatively high speed of the tapes, the uncut portion of the web is readily distanced. The oscillating or swinging fingers 10 throw the sheets from the path into the position shown in the drawing above-described and, on account of the spaced relation thereof, an interval is pro vided between the entry of each sheet bx. neath the fingers of such duration as to permit the fingers to rise after depression to operative position. The accumulated sheets are removed from the table 11 as above-described upon a predetermined number having been thrown thereon, and the moving or ejecting apparatus drawn by the cam 24 into the operative position shown in full lines in the drawing, the spring 33, upon the angle between the lever 19 and link 18 becoming more acute, bein compressed in such manner as, upon the block or slide 32 reaching the end of'the guide 37, to throw the same upwardly into engagement with the lower cam or guiding surface of the upper guide or table 11.

It Will thus be seen that I have provided apparatus well adapted to'accomplish the several features of my invention and that the same is of the'simplest, most inexpensive and efficient construction. It will also be noted that the entire action is positive and in no way dependent upon accurate adjustment of parts. The several elements are individually simple and each is compactly and efiiciently disposed with reference to the others, and they collectively constitute a practical machine adapted to reach and maintain the highest speeds of working.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, I intend that all matter contained in the above description or shown in the accompanying drawing-shall be interpreted as illustrative and not in a limiting sense. 1

I desire it also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall there-between.
