SHEET-REGISTERING MECHANISM.

Specification of Letters Patent.

Patented J an. S, 1918.

Application filed July 6, 1914. Serial No. 849 284.

To all whom it may concern:

Be it known that I, LYMAN Mmnnnnrron, a citizen of the United States, and a resident of New York city, in the county of New York and State ofNew York, have invented certain new and useful Improvements in Sheet-Registering Mechanism, of which the following is a specification.

The present invention has reference to registering devices and has for its main object simple and effective means for positively moving the sheet into register with a guide and for maintaining it in register after the registering members have ceased to act upon the same.

The invention consists more particularly in an upper and a lower registering member which engage the sheet on opposite sides thereof and frictionally carry it into register with the guide. In the preferred embodiment here shown the lower registering member is slidably mounted while the upper registering member moves in a curvilinear path. These members move with the same surface speed when engaging the sheet so as to prevent buckling or improper movement of the sheet during the register. In connection with the above there is also employed a top guide which engages the sheet at a point outside the plane in which the lower slid- .able registering member is located. Thls top guide preferably engages the sheet in advance of the time that the registering members take hold of the sheet and stays in contact therewith until after the registering members have ceased to act upon the sheet. The result of this construction is that after the registering members have ceased to move the sheet forward the top guide will prevent the sheet from springing back from the side guide, as it would do if the paper had become buckled during the registering action.

Other features of construction, combination of parts and arrangement of elements will appear as the specification proceeds.

In the accompanying drawings the invention is embodied in a concrete and preferred form but changes of construction may be made without departing from the spirit and scope of the invention as expressed in the appended claims.

In the said drawings:

Figure 1 is a side elevation of a registering mechanism embodying the invention.

Fig. 2 is a plan view thereof.

Fig. 3 is a transverse sectional view on the line 33 of Fig. 1.

Fig. 4 is a longitudinal sectional view on the line 44 of Fig. 3, certain parts being omitted for the sake of clearness.

Fig. 5 is a horizontal section substantially on the line 5-5 of Fig. 4.

Figs. 6 and 7 are views substantially like Fig. 4 and illustrating different stages of the operation from that shown in Fig. 4.

Similar characters of reference indicate corresponding parts in the different views.

1 indicates the bed of the machine piovided with a groove 2 in which the framing 8 of the registering mechanism is adjustably mounted, the said bed being provided with a number of holes 4 into which the bolts 5 may be secured after moving the frame 3 to the desired position.

6 is a shaft forming a part of the feeding machine provided with a bevel gear 7 keyed to the shaft 6 and adjustable lengthwise thereof in a well-known manner. The framing 8 of the registering mechanism carries arotatable shaft 8 provided with bevel gears 9 at its opposite ends, thereby making the device reversible so that motion may be imparted by the said shaft 8 by either gear 9 meshing with the gear 7, the latter being reversed to correspond with the position of carriage 3. Loosely mounted on the shaft 8, or in a bushing thereof, are two supporting arms 10 which carry on their outer ends a shaft 11. Motion is imparted to the gear 13 loose on shaft 11 by means of the gear 12 fast on the shaft .8. The gear 18 also carries a cam 13 which by engaging with the bearer 14 suitably mounted on a stud 15, causes the shaft 11 to be raised and lowered by the rotation of the parts. The gear 13 further carries the upper registering member 16 which, when the arms 10 are lowered and the gear 13 is rotated at definite periods, engages the sheet on the upper sides thereof. A spring 17 urges the cam 13 into engagement with the bearer 14 and provides sutficient tension to exert a pull on the sheet.

Mounted in the sheet support 18 is a slidable lower registering member 19, said lower and upper registering members being in the same vertical plane so that the paper will be gripped between the two. The said lower registering member 19 is provided with a rack 20 which is actuated by a sector :21

mounted on the center 15 and adapted to receive an oscillating motion. In order to impart a uniform surface speed to the said lower member 19, the sector 21 is preferably moved in one direction by gear means, shown here as two

teeth

22 and 23, one of which is carried by the rotating shaft 8 and the other of which is connected to the sector 21. The said sector 21 is further provided with a cam extension 2st adapted to be engaged by the restoring member 25 moving with the gear 13. 26 is a top guide pivotally supported on the center 27 and connected by means of a rod 28 and pin. and slot connection 29 to an extension 30 forming a part of the arms 10. A spring 31 is provided whereby when the top guide is in its lowermost position the paper will be held under slight tension. Said top guide, of which there are shown two in this instance, engages the paper at a point outside the vertical plane of the lower slidably mounted registering member 19. 32 is the guide, in this instance a side guide, against which the sheet is registered.

After the sheet is fed into position between the upper and lower registering

members

16 and 19, the operation of the parts is so timed that the top guide 26 descends and holds the sheet with a slight tension against the sheet support 18. The arms 10 are now lowered, the member 16 meanwhile rotating, and the said member 16 clamps the sheet against the lower member 19. The parts are now substantially in the position shown in Fig. 4 and the upper and lower registering members now move simultaneously at a uniform speed, thus drawing the sheet sidewise into engagement with the side guide 32, the sheet being prevented from buckling or froi otherwise becoming displaced by the top guide 26. When the sheet has been brought into register the arms 10 ascend and the lower member 19 has reached the limit of its motion in one direction, the top guide 26, however, remaining in contact with the sheet, as shown in Fig. 6. The top guide 26 now rises out of engagement with the sheet and the continued rotation of the gear 13 now brings the restoring member 25 over against the cam extension 24f of the sector 21 and moves it back into its original position, thereby advancing the lower member 19 ready to receive a new sheet. This stage of the operation is shown in Fig. 7

It is of course understood that after the sheet has been side registered it will be moved away in the usual manner and brought down to the printing or other machine-to which it may be contemplated to send it.
