REGISTER BLOCK,

Application filed June 29,1922; Serial No. 571,763.

To all whom it may concern:

Be it known that I, Form WALLICK, a

citizen of the United States, residing at Peru, in the county of Miami and State of Indiana, have invented new and useful Improvements in Register Blocks, of which the following is a specification.

My invention pertains toregister blocks, and relates particularly to register blocks for'use uponthe platen of a platen printing press.

It is an object of my invention to provide a register block of a simple and rugged construction which will permit of a sheet to be printed being placed in an accurate registeredposition, andwhich will, of itself, maintain the sheet in such registered position. It is another object of my invention to provide a register block which will prevent rebounding of the sheet when the latter is 'presentedflforcibly, to it, as for my invention will appear from the following description and the claims. annexed thereto. r

I have shown, by way of example, in the accompanying drawing, and described in the following specification, two forms of register block constructed in accordance with my invention. 1 wish it understood, however, that the invention may be embodied in other forms, and that changes may be made in the forms described and shown, without exceeding the scope thereof, as defined in the appended claims.

In the drawings: i

Fig. 1 is a partial perspective view showing a printing press platen having register blocks constructed in accordance with my invention applied thereto;

Fig. 2 is an enlarged plan of one of the register blocks shown in Fig. 1;

Fig. 3 is a section on the line III-J11 of Fig. 2;

Fig. 4 is a plan of a modified form of my register block; and

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

My invention is particularly advantageous where large quantities of printing of the samekind are to be turned out. It is here illustrated as' used in connection with .the printing of a large number of envelopes of approximately the same size.

Referring now to Figures 1 to 3 of the drawing, 10 designates the platen of a Gordon press, having extending across the :center thereof,a tympan strip 11, secured in place by the usual bails 12. This strip is of sufficient width to accommodate the part of the envelope which is to be printed upon, and leaves bare the surface of the platen ateach side thereof. Two register tympan strip 11. Each block includes a member13 having formed therein a lengthwise-extending elongated slot 14, through which extends a cap-screw15 threaded into a suitable hole in the platen face. From the front of the member 13 extends forwardly a tongue 17, formed so as to produce between itself and the platen facea' slot 18 into which the edge of the sheet or envelope may be fed, said slot terminatingin a reg ister shoulder 16. The front end of the tongue is bevelled below, as indicated at19, to facilitate theentry of the sheet or envelope therebeneath. A tapered hole is blocks are used, one at each side of'the formed in the tongue 17, which hole receives a ball 20 in such manner that the 'ball projects beyond the lower face of the tongue, and engages the face of the platen. A leaf spring 21 yieldingly presses the ball 20 against the face of-the platen.

The pressure of the springs balls 20 is such that while no harmful resistance is opposed by the balls to the passage of the sheets or envelopes therebeneath, in being fed to register against the shoulders 16, yet the balls 20 will prevent the rebounding which sometimes takes place when the sheets or envelopes are fed very rapidly, as when fed by automatic machinery. This is an important advantage. Another advantage lies in the fact that the register blocks will retain the sheet or envelope securely in position during the first part of the movement of the platen towards printing position, before it is seized by the regular platen. grippers. Further advantages lie in the ruggedness of construction of the register blocks, their easy attachment, and their lack of liability to get out of Order- By reason of the slot and screw con- 21 upon the v motion with the platen, endwise adjust ment of the block, to accurate register 3P0Sltion, is easily obtained.

A modified form of my improved register block is shown in Figures 4 and 5. In this form the slot 14 of the member 13 is 'enlarged at its upper part, to permit countersinking of the head of the screw 15. In this instance, also, the tongue 17 is made solid, and the ball 20 made to engage .against its lower face, :being mounted in a recess 22 formed in the platen 10, and pressed upwardly by a spring 21.

- Having thus fully described any said invention, what I claim as new, and desire to secure by Letters Patent, is:

it. The combination with a platen member, of :a register block, means for securing the same to the platen, said block having a rigid ffinger spaced from :the platen, and :means associated with the finger and platen for :holding a sheet after being placed against the block. I

2. The combination with a printing-press :platen of a register block having an elongated slot, ascrew disposed in said slot and entering said platen, whereby said block is .adjnstably secured 'to said platen, and a resilient sheet-Vengaging member disposed between said platen and said block.

3. The combination with a platen member of a register block having a projecting guiding tongue :member said block having an elongated slot, a screw disposed in said slot and entering said platen member, and a resilient device associated with one member and engaging the other member.

4. T he combination with a printing press platen of a register block formed with an elongated slot and with an integral ex-tending guiding tongue member, a screw disposed insaid slot and enteringsaid platen, whereby said block is adj ustably secured to said platen and means associated with the tongue and platen for retaining a sheet in position against the block after the same has been presented thereto.

5. The combination with a platen member of a register block formed with an elongated slot and with an extending guiding tongue member, a screw disposed in said slot and entering said platen member, and a resilient device-associated with one member and engaging the other member.

6. A register device including a member for attachment to a platen, a tongue extending forward from said member, ball for operation between said tongue and the platen, and spring means for acting on said ball.

7. A register device including a slotted member, :a tongue extending forward from said member so as to form a register a butment at the base thereof, ascrew forentering the slot of said member and securing to a platen, a ball for operation between said tongue and the platen, and spring means for acting on said ball.

8. The combination with :a .printi ng-press platen of a register device including a :number ha'vingan elongated slot tl'rerein, a screw in said slot and entering :said platen, a tongue extending forward firom'said member :so :as to form a register abutment at the base thereof, a ball disposed between said tongue and said platen, and a spring operating on said ball.

'9. The combination with a printin press platen, of .a register block adjust-a 'ly secu-red thereto and having a register shoulder and a rigid longitudinally projecting i'gui'ding ffin'ger spaced from the platen, and

spring actuatedmea ns opera'tin g b etwe'e'n the tongue and :platen for retaining sheet against sardrslironlder after thesalne has been presented thereto.
