1 Specification of Ltte rs fatent. 13 1918" Application med Aprnso, 191s. seri l No. 231,632.

Be it knownthat I, ROBERT WILDAY, a citizen of the United States, and a resident of the city of New Yorl ,Woodhaven, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Time or Date Stamp, of

which the following is a full,clear, and exact description; 1 a, a l

This invention relates to a stamp of that type having a facewith twelve hour divi= sions thereon and an adjustable arrow associated therewith for indicating the time of dayof the reception or shipment of an artiole, or any other event. p v

The invention has for its general'objects to improve and simplify the constructionof devices of this character so as to be reliable and elficient in use, comparatively simple and linexpensiveto manufacture, and capable of being easily adjusted and remaining adjusted until intentionally changed. L

:A more specific object of the invention is the provision of date stamp including a handle with stamp head} or cushion thereon, with a rotatable spindle within the i handle and having means for holding an arrow aloneor with date stamp type, there being novel means for permitting the adjust ment of the spindle, and means frictionally holding the same in adjusted position.

With such objects "in View, and others which will appear asthe description proceeds, the invention comprises variousnovel features of construction andarrangement or parts which will" be .set forth with particularity in the ,following description and claims appendedhereto,

In the accompany ng illustrate certain embodiments of the invention and wherein similar characters of reference indicate corresponding partsin all theviews." l a,

Figure 1 is a side vlew of the stamp;

Fig. 2 is a; bottornplanf view; Fig. 8 a is a central vertical section I Figj jisa sid viewfwith portions broken drawings, 7 which Fig. 8 is abottoin planwieW of the stamp on the rotary spindle shown in Fig. 4:; and Fig; 9 is an enlarged erspective view of the lower end of the spin .le shownin Fig. 3. Referring to the drawing, A designates thehandle ofthe stamp, which is preferably a one-piece structure embodying a knob or grip {1, a reduced shank 2, an enlarged head 8, and extending almost the full length of the handle member is a bore 4: for holding the spindle or shaft B. The shank 2 at 0pposite sides hasopenings 5 cuttherein and which are elongated longitudinally of the handle so as to expose the shaft B which has longitudinal flutes 6 to permit a frictional hold to be obtained on the shaft by the thumb and first finger of onehand, to permitthe shaft to be turned while the knob l-is gripped in the other hand. The shaft B 1s held in place by a screw 7 which extends axially into the handle from the knob end 1' thereof and screws into the central bore;8 in the top end of theshaft B. Between the upper end of the shaft B and the end wall or surface 9 of thebore 4 is a yielding element, such as a helical spring 10 which serves twopurposes, in thatit constitutesa brake for preventing turning of the shaft 13 too freely and to move the latter longitudinally outwardly with respect to the handle A when the screw 7 is turned back wardlylf In turningthe screw forwardly the shaftB is drawninwardly in the handle against thejc'ompression of the spring 10. l

On' the head end 3of the handle is a rubber cushion or head C of annular or other form which is lformedwith a reduced shank 11 having a circumferential flange 12, the shank entering the cavity or chamber 13 formed in the bottom face of the handle, therebeingan internal annular flange 14 in thefwall ofthe chamber under which the flange 12 on *the attachedishank 11 engages. The cushionC is cemented to the handle so as to make a firmerattachment. In the present instance the bottom face of the cushionhas formed thereon the word Received, as shown inFig. ,2, and also a rubber clock face" dial 1 15 1 having twelve hour divisions.

The cushion C is formed with sockets 16 which are spaced apart, with webs; 17 be-. tween the sockets so that the opposite tan- 55 and having .gripping portions exposed gentiahwalls. of thesockets cannot spread apart, as wouldbe the case if there were only one long arcuate slot to receive the three rubber date slugs 18,. shownjin Fig. 7

The type or stamp cushion C has a central opening 19 through which extends thel'o'wer end of the shaft B, and this lower end of the shaft has'a diametrically extending Tshaped slot 20 for receiving the arrow or indicator stamp 21, which is, of T-shaped'cross-section tofit in; the slot 20 oftheshaft. By turning the shaft the arrow can beadjusted-to any hour division of; the time stamp 15. In the head end of the handle arranged a rubber sleeve 22 which .frictionally engages the shaft to .assist in preventing free. rotation thereof, whereby the arrow cannot shift with respect to the time stamp 15 unless the shaft is intentionally turned.

Instead of formingthe lower end of the shaft orspindle B-wi-th a T shapedslot,'as shown in Figs. 2 and 3, the lower end may have a socket 22 formed in the bottom face,

which socket has aninternal iia nge QS .to

form means forengaging the attaching stud or shank 2d of a rubber type-holding cushion25, the said stud 24 having an external annular flange 26 toengagebehind the flange 23. In the rubber stamp 25, whichis of the same diameter as the shaft, as clearly shown in Fig. 4, is asuitably shapedsocket 27 for receiving the arrow and date type 28, as shownin Figs. 4: and 8, this type being held in place by frictional engagement with the walls of thesocket 27 p V From the foregoing descriptiontaken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the Y invention appertains and whileI have described the principle "of operation, together with'the device which. Inow 'COIlSldGlif/O be the best embodiment thereof,I desire tojhave it understood that the device shown is merely illustrative and that such changes may beinade when ,desiredas fall within the p v scope of the appended claims.

,Having thus described my invention, I

claim as newand desire to secure by Letters Patent: 1

- 1. A stamp of the class described comprising a'handle having a bore providedwith openings at opposite sides, and'a type-carrying shaftrotatably' mounted in the bore case; 51 assesses mama as the said openings to permit the shaft to be turned, and "means for yieldingly resisting the turning of the shaft.

Astampof the class described comprising a handle having a longitudinal bore, a type-carrying shaft disposed in the bore, a screw engaged with the handle and shaft for moving the latter in one direction, and a yielding means acting between the shaft and handle to mOVe the shaft in. the opposite direction and to frictionally bear on the shaft to y-ieldingly resist the turning thereof.

4. A stamp of'the class described comprising a handle having a longitudinal bore provided with openings in'opposite sides of the handle, and means adjustably comiecting the upper ends of the shaft and the'h-andle to axially move the shaft. v I

5. A stamp of the class described comprisin a handle having a longitudinal bo'r'e )rovi ed with openings in opposite sideso the handle, a type-carrying shaft disposed in the bore, a sleeve in the bore for frictionally gripping the"sl1aft,'a screw swiveled in the handle and having a threaded connection with the shaft, and a yielding element through which the screw passes and adapted to be compressed by the turning of the screw in one direction and 'coiipe'rating'withthe screw for longitudinally adjusting the shaft and for yieldingly retarding the turning of the shaft. I

6. A stamp of the class descr'ibed'comprising a handle having a longitudinal bore and a chamber at one end, said chamber being provided with an internal annular shoulder, atype cushion having a'shank' entering the said chamber and provided with an external flange to engage-behind the shoulder of the handle, said cushion being rigidly fiired on the handle and provided with a central opening, and a rotatable type-carrying shaft mounted in the handle and having its typecarrying end disposed in the. opening of the cushion. I

7. A stamp of the class described comprising a handle having a head, atype cushion rigidly attached to the head and having a central opening, a shaft rot'atably mounted in the handle, and-means on the shaft for holding type within the opening of the said cushion.

8. A stamp'of the class described comprising a handle formed of a knob, shankand head and having a bore; a type cushion rigidly fastened to the head and having acentral opening; a shaft disposed'in the bore; and means on the shaft for holding type within the opening of the cushion, thesaid shank having openings exposing the shaft and permitting the same to be gripped for turning.
