NUMBERING-MACHINE.

Specification of Letters Patent.

Patented Nov. 27, 1906.

To all whont it 'lII/Cty concern:

Be it known that I, PETER R. DILL, a citizen of the United States, residing in the borough of Brooklyn, in the city of New York, in the State of New York, have invented cer- I ticularly concerned with the construction and arrangement of the movable type-block, which in most modern automatic machines of this character is provided in each numberwheel above the units-wheel and is arranged to be depressed below the plane of print, so that a non-significantzero shall not appear at the left of the number to be printed. Various arrangements of such movable typeblocks or drop-ciphers, as they are commonly called, have been devised heretofore; but whatever their construction they have constituted heretofore a more or less prolific source of trouble. The printing pressure is great, and in a high-speed printing-press its effect is almost like that of a hammer, and the drop-cipher blocks are therefore sometimes broken or deformed to such an extent as to permit the type-face thereof to fall slightly below the plane of print, when it should be supported firmly in the plane of print.

It is the object of this invention to improve the construction and arrangement of the movable type-block or drop-cipher block, so that it will be better able to withstand the severe usage to which it is subjected without suffering therefrom.

As now commonly employed 'the typeblock is arranged to move radially in the number-wheel and is provided with a foot to cooperate with one side of an undercut groove in the supporting-shaft, so that when the type-block is in the printing position its face shall be supported in the plane of print, and when the type-block is moved with wheels slightly beyond the printing position and then returned the type-block shall be held in its depressed position from accidental movement outward. In such an arrangement in order that the foot of the type-block and the overhanging edge of the slot in the shaft may properly cooperate the point of the foot is made somewhat slender, and the line of pressure when the type-block is in printing position falls but slightly behind the point of the foot, with the result that the foot frequently becomes bent after more or less extended use and fails to hold the type-surface of the block fully up to the plane of print. The object of this invention is to overcome this difiiculty, and in accordance therewith the movable type-block instead of being radially disposed is tangentially disposed in the number-wheel and with respect to the sup porting-shaft. The said shaft is slotted; but the retaining side of said slot does not overhang with respect to a radial line, and the foot of the movable block is correspondingly formed, so that there is a continuous and substantial body of metal between the face of the type-block and the surface of the su porting-shaft when the type-block is in t e printing position to receive the plrinting pressure. By the provision of suc continuous supporting-body of metal the danger of bending the foot of the type-block is obviated and the necessity for frequent repairs is avoided.

The invention will be more fully explained hereinafter with reference to the accompanying drawings, in which. it is illustrated, and in which- Figure 1 is a plan view of a numberingmachine to which the invention is applied, the frame being partly broken out at one side. Fig. 2 is a view in vertical section on the plane indicated by the line 2 2 of Fig. 1, showing the type-block supported in the printing position, the ratchet-wheel being partly broken. away. Fig. 3 is a detail view showing the movable type-block in its depressed position. Fig. 4 shows front, side, and rear views of the movable type-block.

The numbering-machine to which the invention is applied may be of'any usual or suitable construction. As shown in the accomp anying drawings, it comprises a frame a. in which is supported a shaft b. The number-wheels c are mounted to rotate upon the shaft 1) and are provided each with a suitable ratchet-wheel d, the several ratchet-wheels being engaged by graduated pawls 6, carried by a swinging pawl-frame f Oscillating movement is imparted to the latter in the particular machine shown through suitable connections from a spring-supported vertically-movable plunger 9. Hold-pawls h are provided for engagement with the ratchetwheels of the several number-wheels. Any other suitable arrangement of numberwheels and actuacting devices therefor may be employed, the present invention not being directly concerned therewith, except as hereinafter indicated.

In accordance with the present invention each number-wheel c is slotted tangentially with respect to the supporting-shaft b, and mounted to slide therein is a movable typeblock or drop-cipher 7c. The supporting-- shaft b is grooved or slotted, as indicated at b, one side b thereof being adapted to cooperate with the foot of the movable block 7:: as a cam to thrust the block outwardly, while the other side If is adapted to cooperate with the foot of the block to hold the block in its depressed position, as shown in Fig. 3. As will be observed, however, the side 5 does not overhang with respect to any radius of said shaft intersecting any part of said side. The movable typeblock or dropcipher block 70, as clearly shown in the drawings, is of an irregular geometrical shape, its type-surface being oblique with respect to the general axis of the block. On one side the block is slotted, as at W, forming at the lower end a shoulder 763 for cooperation with a bur struck up, as indicated at c, on theside of the slot i in the wheel 0 for the purpose of preventing the sliding of the block entirely out of the slot. On the opposite side the block is notched, as at M, forming a foot 16' to bear on the supporting-shaft 6, its I forward side is cooperating with the edge 71 of the slot 1) in said shaft. As will be ob-- served. upon reference to Fig. 2, the lines of. pressure between the type-face of the block and the greater portion of the bearing-surface of the foot of the block fall entirely within the body of the block, so that there is no tendency to deform the foot in such at manner as to permit the type-surface of the block to fall below the plane of print. At the same time, as will be seen by reference to Fig. 8, the block is held in its depressed position by the cooperation of the edge 5 of the slot in the supportin -shaft and the side in of the notch in the bloc against the possibility of accidental movement .of the block outward.

I claim as my invention 1. In a numbering-machine, the combination of a slotted supporting-shaft, a numberwheel mounted thereon and slotted tangentially with respect to said shaft and a movable type-block mounted in the slot of the number-wheel and having a foot to cooperate with the slot in the shaft, substantially as described.

2. In a numbering-machine, the combination of a slotted supporting-shaft, a numberwheel mounted thereon and slotted tangentially with respect to said shaft, and a movable type-block mounted in the slot in said wheel and having its type-face oblique to its axis and having a foot to 006 erate with said shaft, substantially as descri ed.

3. The combination of a center shaft having a reentrant angular notch at one side, and a type-wheel loosely mounted on said shaft having a depressible type, said wheel having a slot extending from its periphery to the shaft in a direction not radial, and a block carrying the depressible type movable in said slot, said block having its foot formed to interfit with the notched side of the shaft when the type is depressed, and said foot adapted to rest upon the periphery of the shaft when the type is raised and provide a solid bearing betweenthe impression-surface of the type and the shaft. I

4. The combination of a center shaft having a notch or recess at one side, leaving a solid bearing directly above the center of the shaft, and a type-wheel loosely mounted on said shaft having a drop-type whose foot is constructed to interfit with said notch when the wheel is turned in a position to allow depression of the type and to rest upon the top of the shaft and provide a solid bearing between the impression-surface of the type and the center of the shaft when the type is up.

5. A type-wheel for numbering-machlnes having a drop-type movable in a slot oblique or inclined to a radial line.

This specification signed and witnessed this 3d day of April, 1905 PETER R. DILL.
