DATING-STAMP.

Specification of Letters Patent.

PatentedMar. 6, 1917.

Application filed January 20, 1913. Serial No. 742,993.

To all whom it may concern:

Be it known that I, EMIL C. BUEHRER, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Dating-Stamps, of which the following is a specification.

This invention relates to improvements 1n dating stamps. 1

An object of the invention is to provide means of a strong construction and minimum number of parts for changing the dates of the stamp, said means being operated entirely from the outside of the housing.

The invention furthermore consists in the improvements in the parts and devices and in the novel combinations of the parts and devices herein shown, described or claimed.

The invention is in the nature of an improvement upon the structures disclosed in the patents granted to Alexander D. J oslin, Nos. 986,424, dated March 7, 1911, and

1,011,063, dated December 5, 1911, and consists, broadly, in providing a multiple sleeve shaft on which the printing type-wheels are supported, each member of the multiple shaft having fixed thereto one of the typewheels, and each member being extended to the outside of the housing and provided with means for independently rotating the same, whereby the type-wheels may be adjusted as desired.

In railroad ticket oflices and especially ticket oflices in large cities where tickets are sold for use at a future date, it is essential that simple means be provided for adjusting the dating stamp so that the tickets may be stamped with the date on which the same are to be used, and in this connection it is highly desirable that the adjustment or changing of the type-wheels be efiected without the necessity of lifting up the housing which is found on most of the dating stamps now in use. It is also essential in the interests of economy, that a minimum number of parts be .used and at the same time maintain a rigid support for the type-wheels which are subjected to constant hard usage.

One structure which accomplishes the above indicated desirable objects, is shown in the drawings forming a part of this specification, in which Figure 1 is a partial, verti- 66 of Fig. l.

tially on the line 22 of Fig. 1. Fig. 3 is a transverse, vertical, sectional view taken on the line 33 of Fig. 2. Figs. & and 5 are sectional, detail views taken respectively on the lines 4+4 and 55 of Fig. 3 and Fig. 6 is a detail, sectionalvview taken on the line In the drawing, the base or main frame of the dating stamp is indicated by the reference 10 and, as customary, is provided at the rear with a pair of upstanding hinge lugs 11 supporting a pivot pin 12 onwhich 1s swingingly mounted a pivoted housing 13 and a spring-controlled striking arm 1 1 having the usual knob 15. normally locked in engagement with the base 10 by means of a yieldable member 16 having a catch portion 17 adapted to engage beneath a projecting edge 18 formed on the base 10, the arrangement being such that as the housing is dropped down the cooperating members 17 and 18 will automatically engage and lock the parts together, the engagement being broken, when desired, by means of a depressible push pin 19, (see Fig. 6). Removably secured to the housing 13 by means of dowel pins, is the usual printing die-plate 20 carrying type for printing matter which remains unchanged in the stamping of tickets, said die-plate 20 being provided with a central opening 21 through which the type on the type-wheels, hereinafter described, project. The dating stamp is provided with an inking arrangement comprising a type ribbon 22 adapted to be unwound from a reel supported by a cross pin 23 by means of a ratchet disk 24 operated, step by step, by a spring controlled pawl 25 oscillated each time the striking arm is struck. A dragging pawl 26 is provided to prevent any backward rotation of the ratchet wheel 24. and a rotatable cam 27 is also provided adapted to throw the pawls 25 and 26 out of engagement with the ratchet wheel 24 to permit the ribbon to be rewound on the reel at the front of the dating stamp.

The base 10 is provided with a bearing portion. 28 in which is rotatably mounted a multiple sleeve shaft comprising three members 29, 30 and 31 telescoped one within the other and each having portions thereof of the same diameter and all extended to a point outside of the housing and base. The members 29, 30 and 31 are of different lengths, as shown more clearly in Fig. 3,

and secured to the outer ends of each of said members are turning knobs 32 by means of which said members of the multiple shaft are independently rotatable. Rotatable with the sleeve or member 31 is a printing type wheel 33, the same being keyed to the member 31 by means of a ratchet disk 3 lhaving a tongue 35 which engages a keyway 36 formed in the member 31, it being understood that the ratchet disk 3% is rigidly secured to the type-wheel 33. Two other type- wheels 37 and 38 are similarly secured to the members 30 and 29 respectively, of the multiple sleeve shaft, said type wheels 37 and 38 being preferably separated by a spacing disk 39. Each of the ratchet disks secured to the type- wheels 33, 37 and 38 is engaged by a spring controlled detent 4L0, said detents being provided in order to insure the proper alinement of the type on the type wheels, and permit the type-wheels to be rotated in either direction by means of the turning knobs 32. Also supported by the multiple sleeve shaft at its inner end and rotatable thereon, are two other printing type wheels 41, the same being notched on their peripheries and adapted to have said notches engaged by yieldingly controlled pivoted detents 42, said detents 42 being provided with upwardly projecting finger pieces 43 preferably arranged in different blanes so that when one of the detents is manipulated the adjacent detent will not be accidentally moved. If desired, one of the members of the multiple shaft may be provided with a groove 4% alining with an opening in the outermost knob 32 by means of which oil can be supplied to the inner portions of the shaft and the shaft is adapted to be held in position by any suitable means such as the groove 45 at the inner end thereof and in which takes a screw or pin (not shown).

In practice, the type-wheel 33 is provided with the names of the months and the knob 32 secured to the sleeve 31, is provided with suitable corresponding marks to indicate the months, the type-wheel 38 is provided with numerals from zero to nine inclusive, and the type-wheel 3'? is provided with numerals from one to three inclusive, the knobs 32 secured to the members 30 and 29 being also provided with suitable marks corresponding to the numerals on the type wheels 37 and 38 respectively. The type-wheels 41 are provided with numerals ranging from Zero to nine, both inclusive, and are used to designate the year, while the numerals on the type- wheels 37 and 38 are used to designate the days of the month.

In use, the type-wheels 41 are changed very seldom and whenever it is necessary to change the position of these wheels, the housing 13 will belifted, the proper detent l2 depressed and the member 29 rotated,

which will in turn rotate the wheel 41 by friction. ii henever it is desired to change the position of either of the type- wheels 33, 37 or 38, the proper turning knob 32 is rotated, the marks on the knobs indicating clearly the position of the type which are obscured by the type ribbon 22. With the means above described, it will be seen that the date may be changed rapidly and easily without lifting up the housing, thus effecting a saving in the time necessary to stamp the tickets with different dates.

Although I have herein shown and described what I now consider the preferred embodiment of my invention, yet it will be understood that the same may be embodied in other structures withinthe scope of the claims appended hereto without departing from the spirit of the invention.

I claim l. A dating stamp comprising, in combination: a plurality of printing type-Wheels, a multiple sleeve shaft tothe parts of which said printing type-wheels are secured and by which said type-wheels are rotated, one part of said shaft being adapted to be rotated relatively to a type-wheel carried by and operable by it, substantially as specified.
