CHARLES SPIELMAN, or RICHMOND HILL, NEW YORK, ssreuon ro M. 1;. some & COMPANY, me, on NEW YORK, n. Y.,A CORPORATION on NEW YORK PRINTERS NUMBERING MACHINE My invention relates to numbering machines adapted to be locked in type forms used by printers and in which the numbers are automatically changed by the pressure of each impression and it is my object to produce a device in which the frame will be sturdy, rigid and strong, which can be quickly and easily machined and in which the type wheels may be easily interchanged. Also to provide a long wearing, easily replaced stop for the plunger and to provide the plunger with a long spring which will have a greatly increased life over the short springs now in use.

In the drawing Fig. 1 is a side view of the assembled frame; Fig. 2 an end view of the frame, partly broken away; Fig. 3 a top View of the frame; Fig. 4 a sectional view of the structure of Fig. 1 on the line H thereof; Fig. 5 a bottom view of the frame; Fig. 6 a side view of the assembled device, partly in section; Fig. 7 a view of the end plate; Fig. 8 a side view of the plunger; Fig. 9 a side view of the plunger showing the stop and spring; Fig. 10 a sectional view of the structure of Fig. 9 on the line 10-10 thereof; Fig. 11 a bottom view of the plunger; Fig. 12 an end View of the device; Fig. 13 a sectional view showing the frame in the shaft; Fig. 1 1 a sectional View through a type wheel and shaft; Fig. 15 a view of the shaft; and Fig. 16 a view of a modified shaft end.

The frame is made in two parts. The part 1 has the base 2, provided with the notches 3 and 4:, near one end, the central opening 5 and the upstanding end wall 6. This end wall is provided with a shaft bearing 7 and a lock screw hole 8. The edge of the base 2 has a recess 9 to hold the spring comb holding the pawls in place.

The member 2 of the frame has a slot 10 cut in it leaving the side and end walls 11, 12 and 13. The end wall has a shaft bearing 1 1 in it and the side walls 11 and 12 each has a depending lug 15 and 16 on its bottom edge. One side, bottom bar 17 is milled to the arc of a circle as best shown in Fig. 1, preferably by running a milling tool in endwise, to give clearance to the type wheels.

The frame is assembled by inserting the lugs 15 and 16 into the notches 3 and 4 and peening the exposed ends over thebase. The

two parts may also be sweated together so that they become an integral structure. This results in a solid, 'rigidframe.

The plunger 20 shown in Figs; 8, 9,10 and 11, has a side out 21 to engage an operating lever and a bore 22 as, a spring seat. The plunger has two holes 23-24 drilled into it to receive the edges of the sto staple 25. The end plate 26 has an opening 2 and guide pins 28 entering apertures in the frame as shown in Fig. 1. The long spring 29 is inserted in the seat 22 and the plunger inserted into the space between the walls 11, 12 and 13 after which the cover plate 26 is screwed into place with the stop in the opening 27. This permits the plunger to rise and fall with each impression, the upper end of the opening acting as a stop on the up movement and the lower end of the opening acting as a stop to hold the plunger in the printing plane when down.

The numbering wheels and operating mechanism therefor are of the usual type and.

form no part of the presentinvention. The shaft, however, is made in such manner that the wheels may be easily removed and replaced if damaged, or where skip numbering is desired.

The shaft 30 has the usual slot 31 to receive the drop 0 characters on the type wheels as best shown in Fig. 14. The inner end of the shaft is reduced in diameter at 32 to enter the bearing 14 in the end wall 13, the shoulder on the shaft fitting solidly up against the face of the end wall and rigidly holding the inner end of the shaft in position. The outer end of the shaft has a; flat face 33, provided with a slot 34 and'the end of the shaft has a second slot therein.

The type wheels are assembled on the shaft,

in the frame, in the usual manner and the and no way to push the shaft out from the other end of the machine. This slot 34 may take the form of a raised lip 36 as shown in Fig. 16.

By this construction a simple, easily assembled and disassembled device is produced Which has long wearing qualities. The stop staple may be easily replaced when worn, the spring may be easily replaced When Weak and the type wheels e'asilyreplaced as desired. we

I claim: r

A printers numbering machine comprising a frame provided with an aperture in an end Wall, type Wheels in said frame, means for moving said type Wheels, a plunger in said frame adjacent the apertured end for actuating the type moving means, said lunger being provided with a bore extend- 1ng substantially its entire length, an actuating spring in said bore, said plunger being provided with two holes adjacent the frame opening, and a stop staple in said holes, the head of which extends into the frame opening and slidable therein With the plunger.

In testimony whereof I have aflixed my signature. i 7 CHARLES SPIELMAN.
