' Application filed April'li, 1907.. Serial Nsc. 867,616.

and VVILLIAM J. BARNETT, Jr., citizens'ofthe United States, and residents of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful 'Im rovements in Handestamps, of which the ollowirigis a full, clear, and exact description, such as will enable those skilled in the art to whichgit appertains to make and use'the same,reference being had to the accompanying drawings, formingpart of this specification. I

The invention relates to that class of hand stamps which are providedwith dating mechanism and in. which the ink is sup lied to the impression mechanism by a trave ing ribbon. It consists in the novel construction, com bination and arrangement of parts, such, as will be hereinafter full described, pointed out in the appended claims and illustrated in the accompanying drawings.

In the drawings, in which similar reference characters designate corresponding parts, Figure 1 is a longitudinal sectional view of a hand stamp embodying the invention. Fig. 2 is a horizontal sectional view. Fig. 3 is a front elevation with the front door removed.- Fig. 4 is a rear elevation, artly insection, with the rear door removed Fig. 5 is a detail view showing one of the ribbon winding mechanisms. Fig. 6 is similar view showingthe other ribbon winding mechanism.

The main part of the casing in which the operative parts are mounted may be of any suitable'construction. In the forward part of the top of the casing is a seat in which is placed the impression plate 1 having on its upper surface the characters to print the permanent part of the imprint. The forward end of the seat is 0 on to permit the insertion and withdrawa of the plate.- The latter is held in place by the spring bail 2 hinged to the casing and operatin'g to engage the hooked end of the lug 3 on the under side of the plate. When the bail is disengaged from the lug the plate can be readily removed from the seat.

In the casing beneath the impression plate 1 is journaled the arbor 4 carryingthe independently rotatable (lies 5, 6, 7. On the peripheries of the diesare characters to des ignate the years, months and days. The peripheries of the dies project through a slot in t impression surface.

.11: impression plate located with regard to the characters thereon for printing the permanent part of theimprint. The die 5, whichis rotatable on the-arbor 4, is adjusted by the wheel 8-on the outer end of the shaft 9 journaledin; the casing. On the inner end of the shaft is the gear 10 meshing with the gear 11 fast on the side of the die 5. By

turning the wheel 8 the die 5 can be adjusted so that the desired characters on its periphery will project through the slot inthe 1mpression plate. On the shaft 9 outside of the casing is the indicating dial 12 having char acters to corres ond with those on the pe' riphery of the ie 5. As the characters on thedie are not visible the indicating dial facilitates the adjustment of the die so as to present the-desired characters in the im reswheel 13 the die can be adjusted to present the desired characters on its periphery to the The ad ustment of the die 6 is facilitated by the indicating dial 14 fast on the arbor 4 outside of the casing. The die 7 which is also journ'aled on the arbor 4, is adjusted by the wheel 15 on the shaft 16 journaled in the casing. On the insion surface. The die 6 is fast on the ar or 4 and by turning the latter by means of the ner end of the shaft 16 is the gear 17 meshing with the gear 18 fast to the die 7. For the latter the indicating dial 19 is mounted on the shaft 16 outside of the casing to aid in its adjustment. The dies are held against accidental displacement by the spring-pressed detents 20 In regard to the dies 5 and? the detents engage radial. sockets on theirouter faces; as to the die 6,-its controlling det'ent engages sockets in the periphery of the indicating dial 14.. By means of their respective operating mechanisms any one or all of the dies can be adjusted to present the desired date in the. im ression surface. It is to be observed that t e casing adjacent to the operative shafts and arbor of the dies is -recessed so that the projecting ends will be inside of the general configuration of the cas-, ing and thereby protected against injury.

Cooperating with the impression surface to form the imprint is the hammer 21 carried by the arm 22 pivoted to the rearend of the casing. The hammer is normally held ina raised position by the spring 23 interposed between the arm 22 and the top of the easing. In the face of the hammer is a seat in which is held .the platen 2-4 by the screw 25. Onthe top of'the hammer is the cushion 26 of cork or other suitable material held in place by the-retaining ring 27 screwed onto the crown of the hammer. When the hammer is pressed downwardly against the action of the spring 23 the platen 24 presses the article placed beneath the same onto the impression surface formed by the plate 1 and the dies 5, 6,7 to form the imprint.

1 spindle 31 ournaled 1n the casing.

Ink is supplied for the imprint by the ribbon 28' passing over the im ression surface beneath the hammer. Pre 'minary to its insertion in the machine the ribbon is Wound on a spool having a hollow rectangular core adapted to fit the arm 29. By means of the union joint 30 the arm 29 is hinged to the Through s connection the arm can be turned down through the opening in the bottom of the casing so that the spool can be placed on the same. As the main part of the arm is rectangular and fits the core of the spool the latter is non-rotatable thereon. The free end of the arm is rounded and when in place is journaled inthe annular lug 32 rojecting inwardly from the side of the caslng. The lower side of this lug is open to admit the end of the arm and the latter is held in the lug by the thimble 33 screwed onto the lug. The ribbon leaves the arm 29 and passes around the slack-adjusting roll 34 carried by the yoke 35 journaled at its ends in the casing.

- A spring 36 presses the yoke so that the roll exerts a tension on the ribbon. The ribbon then passes over the impression surfaceformed by the plate 1 and the dies 5, 6, 7 and leads through the slot 37 to the sleeve 38 to which its end is secured in any suitable manner. The sleeve 38 is keyed on the shaft 39 journaled in the casing.

Mechanism is provided for moving the ribbon in either dlrection across the impression surface. The lower end of the arm 22 projects into the casing and is connected by the wrist-pin 40 with an end of the link 41. The other end of the link is pivotedby the pin 42 with the upper end of the lever 43 journaled at its lower end on the shaft 39. On the pin 42 is the double pawl having its arms 44 and 45 extending in opposite directions. The pawl-arm 44 operates to engage the ratchet-wheel 46 loosely j ournaled on the shaft 39. To the side of the ratchet-wheel 46 is secured the gear 47 meshing with the gear 48 on the spindle 31.

through the intervening gears the arm 29 on the spindle 31 is rotated to wind the ribbon onto the spool carried by the said arm. The pawl-arm 45 operates to engage the ratchetwheel 49 on the shaft 39. When'this ratchet wheel is turned by its pawl-arm the shaft 39 is rotated to wind the ribbon onto the sleeve 38 carried by said shaft. When the arm 22 is moved the link 41 connected with it oscillates the lever 43 and rocks the double pawl IIIOVCS gagement When the ratcheti wheel 46 is turned by the pawl-arm 44,

at the upper end of the latter. The rocking of the double pawl, depending upon the engagement of either of its arms with its respective ratchet-Wheel, rotates either the sleeve 38 or the arm 29 to move the ribbon in one direction or the other through the machine.

Mechanism is provided for automatically operating the double pawl to cause the ribbon first to travel in one direction through the machine and then to reverse the movement so that the travel will be in the opposite di rection. On the shaft 39 is the gear 50 meshing with the gear 51 on the shaft 52 journaled in the rear of the casing. The shaft is screw-threaded and carries the traveler 53 threaded thereon. When the shaft is rotated in one direction and then oppositely the traveler moves back and forth across the machine. Above the shaft and parallel with it is the guide-rod 54 longitudinally movable in hearings in the sides of the casing. On this guide-r0d the upper end of the traveler At one end of the guide-rod is the pin 55 having a loose connection with one end of the bell-crank 56 pivoted to the side of the casing. The other end of the bell-crank is connected by the link 57 with the dog 58 pivoted to the casing above the double pawl. On the axis pin of the pawl is the lever 59 95 carrying at its upper end the weight 60. The lever extends upwardly between the arms of the dog58 and the latter operates to move the lever and to shift the weight from one side of the pivotal point of the pawl to 100 the other side to oscillate the pawl. This movement of the pawl causes one or the other of its arms 44, 45 to engage with its re spective ratchet-wheel. The weight not only aids in the throwing of the pawl, but 105 also presses the operating pawl-arm into enwith its ratchet-wheel. The movement of the traveler 53 across the machine is limited in one direction by the pin 55 on one end of the guide-rod and in the oppo- 0 site direction by the adjustable collar 61 on the other endof' the guide-rod. 'l .--he -guiderod is graduated so-thatthe moveinentof the traveler can be regulated by adjusting the collar 61. The traveler engaging "either the pin 55 or the collar 61 moves the guide-rod ongitudinally in its hearings to shift the pawl through the intervening mechanism.

In the front and rear of the casing are-the hinged doors (52 normally held closed by the springs 63 secured to them 'and bearing against the casing on the opposite sides of the hinged connections. By means of these doors and the open bottom of the casing 'a ccss to the operative parts within the casing can be had.

The operation of the machine is as follows:

It is assumed that the dies have been ad justed to present the required date in the IIIiPIOSSIOIl surface and that the ribbon has tance so that the arm 44 engages with the succeeding tooth of the ratchet wheel46.

, tion, thereby reversing thetravel of the ribbeen placed in the-machine and the connections made and that the double-pawl has v been thrown so that its arm 44 engages the ratchet-Wheel 45 as shown in Fig. 1 of the by the latter winds a short length of the ribthe pawl-arm 45 in engagement with the wind it on the sleeve 38. With the reversal of the ribbon the gear is'also reversed,

opposite direction.

drawings. The article to be stamped is placed on the impression surface above the ribbon and the hammer 21 is struck to make the imprint. When the hammer descends the lower end of the arm .22 moves to the rear and through the intervening connections the double pawl is also moved a short dis- When the hammer is released thespring 23 raises the arm.22 and the lower end of the latter moves forward a short distance... Through the intervening connections the pawl is rocked so as to rotate the ratchet wheel 46-. The. rotation of the ratchetwheel, through the intervening gears 47, 48, rotates the spindle 3Land the'arm 29 carried bon upon the spool carried by the arm. At each movement of the hammer this is repeated and the ribbon is gradually wound ofithe sleeve 38 onto the spool carried'by the arm 29 so that the ribbon is fed intermittently across the im ressionsurface. The travel of the ribbon rom the sleeve 38 to the spool on the arm 29 continues until the reversing mechanism operates to change the direction of the ribbon. While theribbon is passing from the sleeve 38 to the arm 29 the traveler 53 is moving along the guide-rod 54 from the adjustable collar 61 towards the pin 55. When the traveler strikes the pin 55, or the end of the bell-crank 56 on said pin, the guide-rod is moved longitudinallyv to the right. This movement of the guide-rod oscillates the bell-crank and the latter through the connecting link 57 turns on the dog 58 to the rear. The dog throws the lever 59 and the weightfiO carried by it to the rear.. The lever rocks the double pawl on its axis so that the pawl-arm 44 disengagesthe ratchetwheel 46 and the other pawl-arm 45 engages the ratchet wheel 49 on the shaft 39.- With ratchet-wheel 49 the subsequent movements of the arm 22".throug'h the striking of the hammer will rotate the shaft 39 to unwind the ribbon from the spool on the arm 29 and which turns the screw-threaded shaft in the This causes the traveler 53 to change its direction and to move from the pin towards the collar 61.- When the traveler strikes the collar the guide-rod, 54 is moved to the left and the bell-crank 56 is thereby moved to operate the dog 58 to. throw the double pawl to its original posibon again. I This is repeated until the ribbon is exhausted and needs replacing. By adjusting the collar 61 on the guide-rod according to the length of theribbon the reversing mechanism can be regulated to act as thelend of the ribbon isreached by either winding mechanism.
