ALINING DEVICE FOR, PRINTING-PRESSES.

Specification of Letters Patent.

Patented Aug. 2'7, 1918 Application filed November 14, 1916. Serial No. 131,343.

United States, and residing in Huntington Park and Inglewood, respectively, in the county of Los Angeles and State of Califor nia, have invented certain new and useful Improvements in Alining Devices for Print ing-Presses, and do hereby declare that the following is a full, clear, and exact description of the same. 1

This invention relates to alining devices for printing presses and more especially to bed and platen type of presses in which the sheet to be impressed is fed by hand, and the principal object is to provide a device that perfects the alining of the sheet without interfering with the grippers.

It is also an object to provide'a simple and light device that is readily attached to, and in any position on the tymp'an vsheet and one other movable part of the press, preferably the gripper bar. i

It is also an object to provide the part to be aflixed to the tympan so that it may be readily separated from the more fixed portion of the device, aswellas being easily adjusted when inoperativeposition.

It is a still further object to provide a spring friction tongue that holds the sheet 1 during the alinement, which in this device is gradual and smooth.

In the drawings accompanying this specification Figure 1 is a perspective view of a platen and the adjacent gripper bar, the parts being broken away and the press open and the gage retracted to the feed position,

while l Fig. 2 is a'plan of the same, in the advanced or alined position, and

. Fig-3 is an end elevation of Fig. 2, on the same enlarged scale, or approximately twice the size of the device.

Fig. 4 being a side elevation.

Complicated and cumbersome devices have been invented to accomplish the result ob tained by the undersigned, but these have been expensive to build and more difficult to install and not readily adaptable to the v I use ofthe small job printer.-

This invention overcomes the above obections, and as pomted out more specifically 1n the followlng, together with the drawings filed herewith in which numerals are used to designate the same parts in the different views, the numeral 6 designating the platen of a hand fed press, with a tympan sheet secured thereon by the clamps 7 the adjacent gripper bar being numbered 8 with a gripper 9 secured thereon in the usual manner.

All portions of the device that can be are preferably formed out of sheet metal, that on the tympan being tempered; the main portion 10 has projecting therefrom the parallel prongs 11, 11 which are in opposition to the sharpened end 12 that is so formed as toslip under the tympan sheet after theprongs have been engaged in the usual manner as shown in Fig. 1.

This plate 10 is provided with a pair of slots 14, parallel to each other and with the sides of the plate, in whichare engaged the teeth 15 formed as guides on the gage 16 normally placed parallel with the sheet to be registered, and this gage is preferably provided with a lip 17 that overlaps the sheet.

Extending rearwardy from the gage and at right angles thereto is the bar 18 preferably formed integral therewith, this bar being inclosed and guided by theslide 19 formed upon the plate 10, the bar being of such length as to always extend beyond the rear of the slide 19 that holds the same parallel with the slots 14. V

This rear end. oflS is connected to the link 20" by means'of the stud 21, this stud forming one hook for the tension spring 22 the other end of this coiled spring being secured to the stud 23 fixed to the slide and of such length as to return the gage to the alined position when released from the retracted position.

Theother end of the link 20 is pivoted to the short arm 24 of the bell crank lever formed by this and the arm 26 and pivoted at 27 to the plate 28 secured by rivets or' otherwise to the plate 10, the opposite end having a lip 29" forming a finger hold and T fadj acent thereto an-upset 30 to form a elamp and guide for the clamp tongue 31, formed of spring material and adjustably held by the grip 30.

The outer end of the arm 26 is also provided with a headed stud 34, over which is hooked the loop 35 so formed of metal as to be readily moved from the head but normally held by tension in proper position, this loop being preferably connected to a butter tension spring 36, of greater tension than the spring 22, the other end of the spring 86 being connected to the operating cord 38, that is secured to and adapted to be wound on the reel shaft 39.

This shaft 39 is freely movable in the bearings formed on the gripper bar plate 40, the shaft having a head 41 and threaded at its other end to receive a lock nut 42 outside the bearing. This plate 40 is also preferably formed of sheet metal folded upon itself to form the bearings, the contacting fiat portions being slotted longitudinally and in the direction of the pull, so that it may be adjustably secured by a bolt 44: to the gripper bar 8.

The operation and installation will be readily understood, the opening of the press and separation of the platen and bed with the movement of the gripper bar, overcoming the tension of the spring 22 and retracting the gage 16, so that a sheet with its edge 45 may be placed in contact therewith or approximately so, and then as the press is closed, registered or alined to the correct position as indicated by the dotted line 46. The plate 10 is readily removed, the loop removed from the stud 34, the locking nut loosened, and the cord wound upon the reel, until such time as it is necessary to again use the apparatus. Adjustment is effected in the same way by operating or varying the amount wound on the reel, and the grippers are free and there is no pounding or noise in the gradual change effected in the alinement, under tension of the clamp tongue 31. 7

Having thus described our invention, what we claim is: I

1. An alining device of the class described, comprising a plate provided with opposed puncturing means for securing the same to a tympan, a gage slidably mounted thereon, tension means carried by said plate normally urging the gage into advanced position, and adjustable means to vary the throw of said gage.

2. An alining device of the class described comprising a plate provided with rear-' wardly projecting prongs, and a solid opposed forward cutting extremity each adapted to engage under a tympan sheet to hold said plate securely thereto, a. slide engaged in said plate, agage on said slide, means carried by the plate to automatically move said slide into sheet registering position, and means to connect said slide moving means to a part movable in relation to said plate.

8.
