SHEET-STRAIGHTENING DEVICE.

Application filed October 5,1921. Serial No. 505,660.

To all whom it may concern Be it known that l, EDWARD Born, a citizen of the United States, residing at Chicage, in the county of Cool: and Fitate of Illinois, have invented certain new and useful Improvements in Sheet-Straightening lDevices of which the following is a specification.

This invention relates to improvements in sheet straightening devices, particularly adapted though not necessarily limited in its use in connection with automatic multigraph machines, and one of the objects of the invention is to provide an improved. simple, durable cheap and efficient device of this character for automatically straightening the sheets and arranging them in a straight pile as they are delivered from the machine.

A further object is to provide an improved machine of this character which is adapted to be adjusted to compensate varying sizes of sheets delivered from the chine.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear. the invention con sists in the features of novelty in substantially the construction, combination and arrangement of the several parts, hereinafter more fully described and claimed and shown in the accompanying drawing illustrating this invention and in which- Figure 1 is a top plan view of the device.

Figure 2 is a front elevation.

Figure 3 is a view taken on the left hand side of Figure 2.

Figure t is a view taken on the right hand side of Figure 2.

Figure 5 is an edge view showing a modification.

Figure 6 is a diagrammatic view of a modified form of operating mechanism.

Throughout the specification and claims the term sheet will be employed to designate the article which is delivered from. the machine to this straightening device to be piled therein, but it is to be understood that this term is to be construed broadly so as to include not onlya sheet of paper but a card or any other article of a similar nature.

Referring more particularly to the drawing the numeral 10 designates a supporting of the support base which may be of any desired size and configuration and constructed of any suit able material. This base supports the right portion of the stop 11.1, and adjacent the base of the upright the top is prefer ably shaped to form a handle 12 by means of which the stop may be adjusted. To that end the stop is preferably provided with spaced parallel arms 13 which extend into guides or sleeves 14: formed in any suitable manner but preferably embody tubular portions secured or held in position upon the support 10 so that by grasping the portion 12 of the stop 11 the latter may be adjusted with respect to the guides so as to position the stop in accordance with the size of the sheet to be delivered from the machine. If. desired another member 15 having spaced arms 16 may be provided at the forward end of the guides 1a to telescope therewith.

Later-ally disposed with respect to the stop l1 and arranged on opposite sides thereof are additional stops 17-48. The stop 17 is secured to the base 10 for adjustment with respect thereto and in a direction transverse to the direction of feed of the sheet in any desired or suitable manner such by means of fastening wing nuts 19, which engage threaded projections. 20 on the stop 17 and which projections 20 pass through suitable slots 21 in the support 10 so that the nuts 19 will be disposed. on the lowe= face of thesupport and by loosening these nuts '19 the stop '17 may be adjusted as desired and then secured in position by tightening the nuts.

The stop 18 is provided with projecting portions 22 which extend through an clon gated slot 23in the support 10 so to project therebeneath and the slot 2 3 is of a considerable length so as to permit the stop 18 to be reciprocated in a direction towards and away from the stop 17 and with respect to the support 10.

Any suitable means may be provided for reciprocatingthe stop 18 but a suitable and efficient means embodies a bar or rod 2% arranged beneath the support 10 to slide in suitable guides or bearings 25. One end of the element 2% is threaded as at 26 and passes through the projecting portion 12 of the stop 18. Nuts 27 engage the threaded portion of the element 2% on opposite sides of the projection 22 so as to secure the stop 18 to the element 24 and for reciprocation therewith.

This eiement 2 1- also extends through a suitable guide or bracket 29. A link 30 is pivotally connected by one end with the element 2st and by its other end with a rod or bar 31, which latter is aranged at a right angle to the element 24 and passes through a suitable guide or bracket 32. The free end of the element 31 is connected by means of a suitable connecting bar or rod 33 with the operating part of the machine so that when the bar 33 is moved in one of the directions indicated by the arrow in Figure 1, the bar 31 will slide through the bearing or bracket 32 and through the medium of the link 30 will cause the element 24; to slide through the brackets or bearings 2529, and cause the stop 18 to be moved towards the stop 17. When the bar 33 is moved in the opposite direction'the stop 18 will be correspondingly moved away from the stop 17.

Another stop 3a is also provided upon the support 10 and this stop3 t is arranged opposite the stop 11 and intermediate the stops 1718. This stop '34 is adapted to be reciprocated toward and away from the stop 11 and its movement is simultaneously with the movement of the stop 18. To that end the stop 34; is provided with a projecting portion 35 connected therewith and which extends through an elongated slot 36 in the support 10. A bar or rod37 is arranged beneath. the support 10 which passes through a suitable guide 38 and also passes through the projecting portion 35 oi the element 3d. Fastening nuts 39-40 are threaded upon the element 37 and clamp the projection 35 of the stop 34: therebetween so as to connect this stopwith the element 37. A link 11 is pivotally connected. by one extremity to the element 37 and by its other extremity is pivotally connected with the element 24- so that when the element Q-t is moved the stop 34- by reason of its connection therewith will. also be moved.

It is thought that the operation of this :device will be clearly understood from the foregoing but briefly stated it is as follows. The straightening device with its parts shown in the position illustrated in Figure 1 is open to receive 'the sheets. As the sheets are delivered from the machine they will advance in a direction toward the stop ".11 and will be delivered upon the support 10 between the stops 11.'17l8-34e After the sheet has been thus delivered and during a further operation oi the machine the bar or rod 31 will be moved in the direction indicated by the arrow and this movement will cause the stop 18 to approach the stop 17 and the stop 34; to approach the stop 11 so that these two stops 18 -34 will be given a reciprocatory movement to engage the edges of the sheet, the stop 18 forcing the sheet towards the stop 17 and the stop 34; at the same time forcing the sheet towards the stop 11. As the next sheet is delivered to be superposed upon the delivered sheets the same operation will be performed and it will thus be seen that by continued operation or reciprocation of these stops 183t the sheets will be piled evenly upon the support 10.

By the provision of the connection as herein shown between the steps 18 and 3d and their reciprocating operating elements and the adjustable connection of the stop 17 with the support 10 as well as the adjustable connection of the stop 11 with the support 10, it will be manifest that these steps may be adjusted relatively with respect to each other so as to compensate the varying sizes of sheets.

Obviously the stop 11 may be acjustably connected with the support 10 in any suitable manner such as by passing the arms 13 thereof into apertures or openings 42 opening through the edge of the support 10.

In Figure 6 there is shown a modified form 01'? operating mechanism and in lieu of the links 30 and 11 as shown in Figure 1 bell crank levers 43 and 46 are provided, the former forming a connection between the element 24 and the operating rod 31 and the latter forming a connection between the element 2% and the element 37.

VVhile the preferred form of the invention has been herein shown and described it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts, within the scope of the claims, without departing from the spirit of this. invention.

What is claimed as new is l. A device of the character described embodying support, a fixed stop, a movable stop, an operating element connected with the movable stop, a main operating element operating at substantially right angles to the first recited operating element, and a link, one extremity of the link being pivotally connected with each of the said operating elements, the said main operating element being movable forwardly and backward-1y and operating to impart a positive movement to the movable stop in both directions of its movement.

2. A device of the character described embodying sheet receiving support, fixed stops cooperating with the support, movable stops co-operating with the fixed stops to engage the edges of the sheets and move them against the fixed stops, an operating element, links detached from the support and connected with the said operating element, and means connecting the movable stops with the respective links for movement thereby, the last recited means embodying an adjustable connection between the links and the respective stops.

3. A device of the character described embodying a sheet receiving support, fixed stops co-operating with the support, movable stops co-operating with the fixed stops to engage the edges of the sheets and move them against the fixed stops, an operating element movable forwardly and backwardly, members connected with the said operating element, and means connecting the respective movable stops with the said members whereby a positive movement will be imparted to the movable stops upon the movement of the operating element in each direction of its movement, the said means embodying an adjustable connection between the said members and the respective stops.

In testimony whereof I have signed my name to this specification on this 1st day of October, A. D. 1921.

EDWARD BURD.
