HICKOK MANUFACTURING coMrANY, or HARRISBURG, PENNSYLVANIA, A 00320- RATION or" PENNSYLVANIA SHEET nmnoTING MEANS Original application filed June 10, 1927, SeriaLNo. 197,977. Divided and this application filed December 4, 1929.

The present invention relates tomeans for controlling the movement of sheets, as for example in their passage through instrumentalities or apparatus foroperating on the sheets, the feeding of such sheets to such mechanisms, or theirtransfer from one to the other, etc. This is a division of Serial No. 197,977; V

The object of the present invention is to provide mechanism of a simple and effective character that is controlled by the sheet itself, so that the operation of the mechanism is dependent onthe presence of the sheet and is thus timed by the sheet on its arrival at a predetermined point.

The present embodiment of the'invention is in connection with a ruling machine of the L-type, said invention forming the mechanism for starting the sheets out'of the corner or from the delivery mechanism of the first ruling apparatus to the feeding means of the second ruling apparatus. V v.

The other is an oif-earrying conveyor at right angles tothe tapes 14 and consisting of a set of tapes 25.

The means for causing the transfer of the sheets from the tapes 14 to the tapes constitutes the essential feature of the present invention.

Serial No. 411,629.

ATENT OFFICE A shaft 26 (Figure is located longitudinally of the tapes 14 at one side of the same and is parallel toaroller 27, around which the tapes 25 pass. The shaft 26 and roller 27 are driven in unison by sprocket gearing 28, and the roller 27 in turn is driven by a sprock et chain 29.

g On the shaft 26 is a conveyor member in the form of a starting roller 30, the front that in turn is connected to an adjusting chain 34. p

Secured to the stop bar 32 is a bracket 35 (Figure4),'in which is journaled a rock shaft 36.= This rock shaft carries a crank arm 37, on which is journaled a gripping roller 38. The roller 38 is capable of swinging downwardly into coaction with the starting roller30 and upwardly out of coaction therewith. To this end the rock shaft 36 is provided with another crank arm 39 connected by a link 40 with the rod 41 of a piston 42. The piston is located in a cylinder 43, mounted as Shown at 44'on the stop bar 32. A third crank arm 45, secured to the rock shaft 36, has connected thereto a spring 46 that resists the movement'of the piston 42 in one direction. The said piston 42 and cylinder 43 constitute a pneumatic; motor of the suctiontype.

Connected to the rear end of the cylinder 43 is a suction conduit 47, having at its rear end a T-coupling 48. To one end of said coupling 48 is fitted a flexible suction hose 49 that leadsto the intake end of an exhaust pump'50 (Figure 1), driven through gearing 51 from a shaft 52 belted to a driving iblevent conduit 52 leading to a relief nozzle 53 adjustably bracketed as shown at 54 on the stop bar 32. On the lower end of the nozzle 53 is a forwardly extending upwardly curved shoe 55 provided with one or more vent ports 56 (Figure 7) therethrough that are in communication with the interior of the nozzle 53,- (Figure Said nozzle is furthermore provided in one side with a series of intake ports 57 that may be more or less closed by a rotatable controlling disk 58 having ports 59 adapted to move into and out of alinement with the parts 57. This provides means for varying the force of the air suction that acts on the motor 42-43.

The operation of the mechanism is substantially as follows: Assuming the conveyors are in motion, as long as the relief ports 56 are open, the pneumatic motor 42-43 is idle and the spring 46 is acting to hold the gripping roller 38 elevated or in an idle position. Assuming, however, that sheets are being fed successively through the first ruling apparatus 8, these sheets will be successively delivered from such apparatus by the tapes 14. lVhenever a sheet is carried upon said tapes, it will strike and be stopped by the bar 32. Obviously this will carry the margin of the sheet between the starting roller 30 and the gripping roller 38, the roller 38, as already explained, being in its elevated position, but as the sheet is brought up into contact with the stop bar 32, it will also be brought beneath the shoe 55 and across the relief ports 56, as illustrated in Figure 5, a portion of a sheet being there shown at A. IVhen this occurs, the intake of air through the ports 56 is prohibited, and as a consequence air will be exhausted from the rear end of the cylinder 43, causing the piston 42 to retreat to that end. This, as will be clear by reference to Figure 4, will swing the arm 39, rocking the shaft 36, and causing the gripping roller 38 to move downwardly, thus carrying the margin of the sheet into active contact with the roller 30. The roller 30 is constantly rotating and consequently the sheet will be gripped, and started in a direction at right angles to the conveyor tapes 14, until it is caught by the tapes 25 (Figures 1 and 3) and carried away. It will be noted that this transfer mechanism being all mounted on the stop bar 3:2, is adjustable with the same, so that the mechanism can be properly placed according to the size of the sheet to be operated on. Moreover the force of the suction through the ports 56 can be varied by adjusting the disk 58, so that the mechanism will successfully operate whether the sheets are very heavy or very thin. Furthermore it will be noted that this mechanism is operative irrespective of the surface speed of the starting roller 30, so that said starting roller may be run at different speeds in order that sheets of different sizes will be properly spaced and properly fed to the second mechanism.

With this structure, it will be evident that the operation of the feeding mechanism is under the control of the sheet itself, so that whether sheets be spaced far apart or close together, whether they lag in their travel,

or are advanced, whenever a sheet comes into position, it controls its own start on to the second conveyor 25.
