ELLIS W. COOPER, 0F BLOOMFIELD, NEW JERSEY, ASSIGNOR TO R. HOE AND (10., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

FOLDING DELIVERY.

To all whom it may concern:

Be it known that I, ELLIS W. COOPER, a citizen of the United States, residing at Bloomfield, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Folding Deliveries, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in folding deliveries.

Folding deliveries of a certain class comprise a rotating sheet carrier provided with grippers or similar devices for seizing the leading edge of the sheet and forwarding the same, a tucking blade, and a second rotary carrier provided with nipping jaws into which the tucking blade tucks the sheet in order to fold it 01f. WVhere such a delivery is constructed to fold off different sizes of sheets, it is necessary to make the tucking blade adjustable circumferentially of the cylinder, so that no matter what the size of the sheet may be, the tucking blade will occupy the proper relative position with respect to the grippers to impart the desired fold to the sheet. This circumferential adjustment of the tucking blade, however, requires a corresponding circumferential adjustment of the nipping jaws in order that the relation between the blade and jaws may not be disturbed, and also requires an adjustment of the means for operating the grippers, so that the grippers may release the sheet at the time the tucking action ocours.

It is one of the objects of this invention to produce an improved folding delivery embodying a rotating carrier provided with devices for holding the leading edge of the sheet, and a tucking blade which tucks into nipping jaws on a second rotary carrier; the construction being such that a circumferential adjustment of the tucking blade with respect to the sheet holding devices also effects a corresponding adjustment of the nipping jaws so that the relation between the two is not disturbed.

A further object of the invention is to produce an improved delivery mechanism embodying a rotary sheet carrier provided with holding devices for the leading edge of the sheet and a tucking blade, and a ro- Specification of Letters Patent.

tating carrier provided with nipping jaws, the construction being such that a circumferential adjustment of the tucking blade with respect to the sheet edge holding devices produces a corresponding adjustment of the nipping jaws, and also simultaneously therewith adjusts the means for operating the sheet holding devices, so that they will release at. the proper time.

lVith these and other objects not specifically referred to in view, the invention consists in certain constructions and in certain parts, improvements and combinations as will be hereinafter fully described and then specifically pointed out.

Referring to the accompanying drawings which illustrate so much of a delivery mechanism as is necessary to an understanding of the invention-Figure 1 is an end elevation of a delivery mechanism embodying the invention. Fig. 2 is a plan View of the construction shown in Fig. 1 so far as it relates to the folding mechanism.

Machines embodying the invention will include a rotary carrier provided with suitable devices for taking the leading edge of the sheet. In the particular construction illustrated, the rotary carrier, indicated at 1, is mounted on a shaft 2 provided with a driving gear 3, said shaft being mounted in the frame. The bearings for the shaft are indicated by bosses 4. In the particular construction illustrated, the devices for seizing the edge of the sheet comprise grippers 5 mounted on a shaft 6 supported and free to turn in arms 7. These arms are supported and fast on an operating shaft 8 journaled at one end in one of the heads 9 of the cylinder, and at its other end in a boss 10 fast in the other cylinder head 11. The end of the shaft is provided with an operating arm 12 which works in a groove 13 (see Fig. 1) in a closed cam 14. 14 surrounds the shaft 2 loosely and is supported by another cam 15, this cam being secured to the frame by bolts 16 tapped into bosses 17. The function of this cam 15 will be explained hereafter. The boss 10 is provided with a gear 18 with which meshes a pinion 19 on the gripper shaft 6. The construction is such that as the shaft 8 is rocked the shaft 6 both moves around the axis of the shaft 8 and also turns around This cam its own axis. This construction of gripper is a well-known one, and any other suitable construction may be substituted therefor.

The sheets may be supplied to the grippers 5 in any suitable way. As shown, they are taken from a platform moimted on crossbars 20, the sheets being deposited on this platform by a traveling carrier comprising chains 21 and grippers 22. As the sheets may be delivered to the grippers 5 in any suitable way, the particular construction of the traveling carrier and platform has no special reference to the present invention and no further description or illustration of it will be given.

Machines embodying the invention will include a tucker blade which may be variously constructed, and a suitable support for the blade. In the particular machine illustrated, the support for the tucker blade comprises heads 23 secured to the heads 9 and 11 of the cylinder by bolts 24, the heads 23 being provided with slots 25, so that they may be circumferentially adjusted with respect to the ends of the sheet carrier. The cylinder has its periphery recessed as shown by dotted lines in Fig. 1, to permit this adjustment. In the construction illustrated, the sheet carrier is provided with two sets of grippers 5, and, therefore, with two tucking blades, one for each set of grippers. The tucker illustrated is of the rocking variety, the blade, indicated at 26, being mounted on a shaft 27 journaled in the heads 23. The shaft 27 is provided with an operating arm 28 carrying a roll 29, this roll running on the face of the cam 15. Constructions embodying the invention will also include a pair of nipping jaws, and as usual in such constructions these nipping jaws, marked 30, will be mounted on a rotary carrier 31 which is supported on a shaft 32. These nipping jaws are operated from an arm 33 which runs on a stationary cam 34 supported on a bracket 35. This construction of nipping aws is a common one in the art and further description. of them is unnecessary.

It will be understood that by loosening the screws 24 the heads 23 which form the support for the tucker blades may be circumferentially adjusted about the shaft 2, and that this adjustment changes the relative position of the tucker blade with respect to the grippers 5, so as to produce a fold of greater or less width, as may be desired.

In machines embodying the invention the construction will be such that when the tucker blades are adjusted as described, the nipping jaws will be correspondingly adjusted so as to avoid disturbing the necessary relation between the jaws and the blade. While this adjustment may be effected in various ways, in the particular construction illustrated, one of the heads 23 is provided with a boss 36 to which is fast a gear 37 which meshes with a gear 38 fast on the shaft 32 which is the shaft of the rotary nipping jaw carrier. lVhen, therefore, the heads 23 are adjusted circumferentially, there will be a corresponding circumferential adjustment of the nipping jaw carrier, so that the relative position of the aws and tucker blade are not disturbed. It may be remarked that the heads 23 are tied together by two braces 39. These braces are ribbed and terminate in feet, the outline of which is indicated by dotted line 40 (see Fig. 1). The feet are secured to the inner sides of the heads 23 by screws 41. This construction of brace gives special strength to the construction. The heads 9, 1O of'the: rotary carrier are provided with slots, the outline of which is indicated by the dotted line 42, to permit the circumferential adjustment referred to. hen the tucking blade and nipping jaws are circumferentially adjusted, the time at which the grippers operate to release the sheet must be changed accordingly. In machines which embody the invention in its best form, the construction will be such that the change in time of operation of the grippers to release the sheet will be effected simultaneously with the adjustment of the tucker blade and nipping jaws. IVhile the means by which this is effected may be varied, in the particular construction illustrated, the shaft 32, which is the shaft on which the nipping jaw carrier is mounted, is provided with an actuator in the form of a cam 43 provided with a groove 44 (see dotted lines in Fig.1). The operation of the grippers to release the sheet is effected by means of a latch 45 '(see Fig. 1) fixed on a short shaft 46 which passes through and is j ournaled in the cam disk 15. In its normal position, this latch 45 forms a part of the outer wall of the groove 13 which is the groove which actuates the arm 12 of the gripper operating shaft 8. The shaft 46 has an operating arm 47 connected to it, this arm being in turn connected to a forked rod 48, the end of this rod straddling the shaft 32. This forked rod has an anti-friction roll 49 fast therein which runs in the groove 44 of the cam 43. In the operation of the mechanism the forked rod is operated by the cam groove 41 so as to swing the latch 45 outward on its pivot 46. This releases the pressure on the anti-friction roll on the arm 12 of the gripper operating shaft and allows the same to swing so as to release the sheet, the sheet at this time having its fold tucked into and held by the nipping jaws. Since the cam 43 is fast on the shaft 32 any circumferential adjustment of the tucker blade and nipping jaws will effect a corre sponding adjustment of the actuator cam.

A holding roll, as 50, may be employed in connection with the nipping aw carrier, as usual in such constructions, and the carrier may be provided with grooves, as 51, engaged by a stripper, indicated at 52, to assist in delivering the sheet therefrom.

Changes and variations may be made in the construction by which the invention claimed is carried into effect. The invention claimed, therefore, is not to be confined to the particular construction herein described and illustrated in the accompanying drawings.

What is claimed is:

1. In a folding delivery, the combination with a rotary sheet carrier having holding devices for the leading edge of the sheet and a tucking blade, of a second rotary carrier provided with nipping jaws cooperating with the tucking blade, means for operating the holding devices to release the sheet, and means for simultaneously adjusting the position of the tucking blade with respect to the edge holding devices, the position of the nipping jaws with respect to the tucking blade, and the holding device operating means.
