HAND-STAMP MACHINE.

Specification of Letters Patent.

Application filed December 10, 1909.

Serial No. 532,394.

T 0 all whom it may concern:

Be it known that I, FRANK lVosmsKi, a subject of the Emperor of Germany, and resident of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Hand-Stamp Machines, of which the following is a specification.

My present invention relates to a hand stamp machine adjustable to print various combinations of numbers such as a series of numbers consecutively or the same number .in repetition as well as other combinations, and further relates to the means for rapidly adjusting the machine to print one or other of these combinations as desired.

In the drawings, which show only one of the forms which my improvements may take, Figure 1 is a horizontal section partly in top plan through a hand numbering machine embodying my invention, said section being taken at a point above the printing wheels; Fig. 2 is a perspective view of the same machine the handle portion and other non-essentials to the present invention be ing omitted; Figs. 3 and it are side elevations taken from the line 3-:t in Fig. 1 looking in the direction of the arrows, por tion of the link 10 being broken away, the two views differing in that Fig. 3 shows the idle pawl in its lowered idle wheel engaging position, whereas Fig. at shows the idle pawl elevated preparatory to adjusting it laterally as hereinafter described Fig. 5 a face view of the idle wheel means on an enlarged scale, the leg of the printing wheel frame and the drum that rotatably supports the idle wheels being broken off Figs. 6 to 9 inclusive are vertical sections partly in elevation, respectively on the lines 66 to 9-9 in Fig. 5; and Fig. is a vertical section partly in elevation on the line 1010 in Fig. 1 looking in the direction of the arrow.

Describing now the devices of the drawings and. reserving it to the claims to point out the novel features and to define the scope of the invention, 1 is the main frame of the machine consisting of a U-shaped portion 1 and a tubular portion 1 projecting from the top of the U-shapcd portion and surround ing a hole therethrough. 2 is the plunger which above bears the usual handle (not shown) and which below supports the usual U-shaped printing frame, the legs of which are shown in horizontal section at 18 in Fig.

1, and between which the rotatable printing wheels 3 are operatively supported in wellknown manner on an axle or drum 25. 4 is the pawl-frame carrying pawls 5 for rotating the respective printing wheels. Compare Figs. 1, 2 and 10. Said pawl-frame is provided with hinge knuckles 6 which pivotally support the frame and its pawls from rod 7 secured horizontally across between the ends of two pairs of links, one pair on a side, each pair consisting of an angular link 8 pivotally connected to the portion 1' of the main frame at 9, and a link 10 pivotally connected at 10 with the leg 18011 that side of the printing wheel frame. All of these parts of the machine are as heretofore.

Referring now more particularly to the present improvement, I have extended the links 10 and connected them across by a shelf 11. A coiled spring 12 surrounds the rod 7 and one of its ends 12 bears againstthe under side of the shelf, whereas its other end l2 bears against the pawl-frame a to carry its pawls 5 toward'the printing wheels so that they are normally in operative contact with said wheels. At one side of the printing wheels, a plain faced idle wheel 14 and three idle wheels 15, 16 and 17 are rotatably mounted on the drum 25. Compare Figs. 1 and 5. This idle wheel means will be described later in detail.

18 is the idle pawl having a hub 19 by which it is slidably supported on the rod 7. This idle pawl has a finger 20 for engaging the periphery of the plain faced wheel 14, or for engaging one or other of the idle wheels 15, 16 and 17, depending on the position of adjustment into which the pawl is slid along the rod 7.

21 is the thumb-piece or that part of the idle pawl which is to be grasped by the operator to adjust the pawl. Said thumb piece has an opening through which is slidingly received a pin 22 that projects horizontally from the end of the pawl-frame 4..

The shelf 11 is cut out to form the notches shown in Figs. 1 and 2 opposite which are the characters C R 2 3 4. These are stamped into the material of the shelf for the guidance of the user in adjusting the idle pawl as will hereinafter appear.

23 is a locking fin on the idle pawl which when the pawl is in its lowered position in Fig. 3 is receivable into one or the other of the described shelf notches, whereupon the pawl is locked againstaceidental lateral displacement along the rod 7. On the other hand, when the idle pawl is pivoted into the raised position shown in Fig. 1, the end of its fin 23 clears the notched edge of the shelf and the pawl can he slid laterally in either direction and its fin let down into any of the other notches. Just as the spring 12 impels the pawlframe 4 toward the printing wheels, so at the same time it impels the idle pawl toward the idle wheel means, because the pin 22 carries the idle pawl along with the pawl frame. This same pin connection keeps the fin normally seated in whatever notch it happens to be left in. Of course, the individual components of the idle wheel means can be any desired, and the characters C R 2 3 4 on the shelf will vary accordingly. Hmvever, in the particular machine shown, the significance of these characters G R 2 3 a is as follows: hen the idle pawl adjusted into notch C, its finger 20 is opposite the leg 18 of the printing wheel frame. but does not touch it. The result is that the pawls 5 are in constant engagement with the printing wheels, and operate them at every down stroke of the plunger, thus giving consecutive numbering, symbolized by the letter (i 0.77

lVhen the idle pawl is in notch R, its finger 20 .is on the plain faced wheel 14, which is of sufficient diameter to keep all the printing pawls off the printing wheels, so that no matter how many times the plunger may be operated, the number printed will remain always the same. This repetition of the same number is symbolized by the letter R. Next come the other idle wheels 15, 16 and 17, respectively, engaged by the idle pawl when adjusted into notches 2, 3 and 1-. Each of these wheels has notches or spaces 26 alternating with unnotched or high portions. The wheel 15 had four of these spaces 26 equidistantly disposed around the wheel, 16 has three, and 17 has two. Moreover all of the wheels have symmetrically disposed ratchet teeth 27 on their outer face, wheels 15 and 17 having eight ratchet teeth and wheel 16 having nine. These teeth are positioned as follows: Thus there .is one at every space of each wheel. The rest are located on the high places between the wheel spaces. Thus an examination of Figs. 7, 8 and 9 shows that wheel 15 has one ratchet tooth 27 on each high place, wheel 16 has two, and wheel 17 has three; Now depending upon whether the idle pawl is in notch 2, 3 or 4 of the shelf to engage idle wheel 15, 16 or 17, will cause the machine to give a series of numbers in duplicate, triplicate or quadruplicate, in other words, a series of numbers 11, 22, 33, etc.; or 111, 222, 333, etc.; or 1111, 2222, 3333, etc. Thus when the idle pawl engages one of the wheels 15, 16 or 17,

every down stroke of the plunger causes the pawl to push against one of the ratchet teeth 27 to give the wheel a partial turn. Successive down-strokes cause the idle pawl to engage successive ratchet teeth, so that sometimes the pawl will be riding on a high part of the wheel and sometimes will drop into the wheel spaces. It is only when the idle pawl drops into the wheel spaces that the printing wheel pawls engage and operate the printing wheels. They are held off the printing wheels, when the idle pawl is riding on the high places of the idle wheels. Therefore it follows that the idle pawl on wheel 15 gives'numbers in repeats of two, 1.1, 22, 33, etc. because there is one high place ratchet tooth between spaces, which means, that following each change of number there in one idle down-stroke of the plunger which leaves the number the same as before. Again the idle pawl on wheel 16 gives repeats of three, 111, 222, 333, etc., because there are two high place ratchet teeth between spaces so that following each change of number there are two idle down-strokes of the plunger that leave the number the same as before. Finally wheel 17 gives re peats of four, 1111, 2222, 3333, etc., because having three high-place ratchet teeth between spaces, there are three idle plunger strokes that leave the number unchanged.

It will be understood that the plain disk 14 is in reality a plain faced idle wheel and that not only it, but also the leg 18 on the idle pawl side of the printing wheel frame are parts comprised along with the idle wheels 15, 16 and 17 under the language of the claims calling for idle wheel means having a plurality of faces arranged side by side. It will be further understood, however, that said language is not to be taken as limited to the particular idle wheel means shown, but to include other different forms of idle wheel means such as wheels having a different number of spaces as may be desired or suitable.

In addition to the features of novelty relating to the adjustment of the idle pawl relative to the idle pawl 1neansthere is also the feature that the idle wheels 11 to 17 may be united to turn as one wheel, in fact preferably consist of a single casting. An ad *antage of this, .is that only one hub-pin 28 need be employed to engage the hubnotches (rand Z). These notches are only needed at the hub-pin and need not extend as shown across all of the wheels. However, when the wheels are a single casting, the lat ter is convenient from the point of view of milling.

There are eight a notches corresponding with the eight ratchet teeth of the wheels 15 and 17, and there are nine 5 notches corresponding with the nine ratchet teeth of the wheel 16. This would make 17 notches in all, but in fact I get along with only 14 by combining wheel 16 with the other two Wheels so that three of the a and Z) notches come together. In addition, this requires doing violence to the even spacing of the b notches which, to be accurate, should be spaced one-ninth of the circumference apart instead. of one-eighth, which is the case where they coincide with the a notches. However, on so small a circumference I have found that the inaceuracyis negligible. In short, that the advantages of the combination, consisting in reducing the number of notches are not discounted by any disadvan tage or lack of perfect operation. lVhcn the idle pawl engages either wheel 15 or 17, these being the wheels with the eight ratchet teeth, it will be apparent that the notches a will be engaged in succession by the hub-pin. Further, that when the idle pawl engages wheel 16, the notches b will be engaged in succession by the hub-pin. Of course, the general purpose of the hub-pin and notches is to prevent back-lash of the idle wheels and inits broad aspect is well known. Finally, there is the feature consisting of means preventing side play of the pawl frame 4 and of its pawls out of working relation with the printing wheels, but without interfering with the pivotal motion of said frame and its pawls. For this purpose, the pawl frame 1 has a vertical slot 29. 30 is a piece of sheet metal supported stationarily from the shelf 11 and the rod 7 and project- .ing loosely into the slot 29, whereby the pawl frame can plvot to and from the printing wheels, but cannot move laterally. The support of the piece 80 consists of the rod 7 received through a hole in said. piece, and further consists of the shelf 11 whose edge is slotted at 11 to receive and interlock with the piece 80 at a slot 30 similarly formed therein.
