Specification of Letters Patent. Patented 001]. 18, 1921.

To all whom it may concern."

Be it known that I, JOSEPH LEVY, a citizen of the United States, and resident of Boston, in the County of Sufiolk and. State of Massachusetts, have invented an improvement in Time-Stamps, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representin 'like parts. I i

My present inventionrelates to stamping apparatus, and more particularly to automatic time stampingapparatusfor printing the date and time of receipt ofletters, pa--' P rs and the like.

In automatic time stamping apparatus of the kind referred to, a date'an'd time stamp is located in a standard and thetiming'element is connected to a clock or clock move-' ment, which may, or may not, be located within the standard. A stamp pad, at tached to an arm pivoted on the base, is movable with respect to the date and time stamp to perform the printing of the date and time indicated on the stamp. In building up the apparatus, it is usual to as semble the elements of the ,date and time mechanism in the standard; This method of assembling necessitates exceedingly careful machine work, and the selling price of Such an apparatus has been so low that the apparatus cannot be marketed at a profit. Consequently,'the manufacturer-has had to choose between going out of business or marketing an apparatus that is so high in price that the sale is limited.

To obviate these objections, I have devised an improved date and time stamp apparatus in which the date and time elements may be inserted in the standard as a unit and which is automatically alined with the stamp pad.

Again, the usual time Stamping apparatus is set by some person in authority, and is not supposed to be tampered with by any person using the apparatus. Asa matter of fact, it is well recognized that a clerk, or other person who is negligent or forgetful, will fail to stamp, for example, all the mail received on a certain day, and the next day or on some later day, will stamp the remainder of the mail, after first altering the indications either as to the time or date. To prevent this procedure, I have devised an improved locking means for securely lock Shaft remote ing the inclosing cover, for the date and timing means, to the standard of the apparatus.

An objectof my invention therefore, is an improved date and time stamp apparatus in which the date and timing elements are inserted in the standard of the apparatus as a unit and in alinement with the stamp pad;

Another object of the invention is the provision of an improved locking means for preventing access to the date and time stamp elements by unauthorized persons.

In the accompanying drawings illustratthe preferred embodiment of my invention,

Figure 1 is a plan view, I

Fig. 2 is a side elevation, showing the improved locking means, r

, Fig. 3 is a plan view of the date and time indicating elements, assembled as a unit,

Fig' 4 is a sectional side elevation of the time stampin apparatus, showing the date and time indicating elements in position, and I Fig. 5 is a sectional Side elevation on the line 55 of Fig. 3. I

Referring to the drawings, 10 designates the base having a hollow standard 11 at one side thereof. This hollow standard 11 is cut away at its front end, as Shown, and is provided with a cross-bar 12, cast integral therewith. Screwed through the cross-bar 12 is a bolt 13, slotted at its lower end at 14:, and with its upper end engaging with a stud 26 which extends through a perforation in the plate 15 of the date and time indicating means. On the top of the stud 26 is riveted a frame 16 carrying the date wheels 17, 17 17 and it will be obvious that by properly rotating the bolt 13 with a screw driver, the date wheels 17, 17 17, may be raised or lowered. A set screw 25 in the plate 15, acts to hold the stud 26, and therefore the date wheels 17, 17, 17, in adjusted position. Mounted for rotary movement in the plate 15, and parallel to the bolt 13, is a shaft 18 provided with a bevel gear 19 on its lower end, which gear meshes with a bevel gear 20 located intermediate the ends of a shaft 21, which extends through the side of the standard 11 and is connected to the driving shaft 22 of a clock 23, of the ordinary commercial type. The end of the from the clock 23 extends through the other side of the standard 11 and is provided with a knurled thumb nut plates 27 27 these side plates being bent at right angles at the top to form resting places 28, 28, for the top plate 29. Dowel holes 30 are drilled through the top plate 29 and side plates 27 27 and in alinement with holes 31 in the top of the standard 11, as shown in Fig. 5. Dowel pins 32 are driven into holes 31 in the top of the standard and engage in the holes in the side and top plates 29 and 27 27 respectively, to positively position the sub-unit. The time indicating mechanism 33 is driven fromthe shaft 18 through appropriate gearing, shown but not described. Screw holes in the top plate 29 are in alinement with threaded holes in the standard 11 for the insertion of screws 34 that cooperate with the dowel pins 30 to hold the sub-unit rigidly in position in such standard.

Pivotally mounted at 34 on the standard 11 is a cover 35 carrying the inking ribbon 36, the cover being cut away on its top surface to provide an opening through which the date and time indicating mechanism may project, as clearly shown in Fig. 4, the ribbon 36 passing over the date and time indicating mechanism. Also pivotally mounted at 34 is a pivoted stamp pad arm 37 carrying the stamp pad 38 at its outer or free end in position to move into and out of engagement with the date and time indicating mechanism. A spring 39 returns the arms 37 to the normal position after each operation.

Firmly attached to the side of the cover 35, by riveting or in any other suitable manner, is one end of a hinge 40, the other'end of which is provided with a slot 41 through which a staple 42, attached to the side of the standard 11, may project, a padlock 43 termediate the ends of the hinge is an extension 44 which when the hinge 40 is in locked position, covers the knurled thumb nut 24 and prevents the same from being rotated.

F rom-the above description, it is obvious that the date and time indicating mechanism, being assembled as a sub-unit in the frame comprised of the plates 15, 27 and 29 and with the dowel holes 30 and 31 drilled in the plates 29 and 27, and in the standard 11, that the apparatus may be assembled cheaply and by comparatively inexperienced help. The work, being practically all machine work, mav be economically performed, and I am thus enabled to produce a high grade apparatus of this character that may be sold at a reasonable price.

While I have described the preferred embodiment of my invention in detail, it is to be understood that I may vary the size, shape, and arrangement of parts within wide limits without departing from the spirit of the invention.

7 Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

In an apparatus of the kind described, the combination of a base and standard, a timing mechanism located on the base and in operative relation to the standard, a date and time indicating unit, cooperating means on said unit and standard for positioning the said unit in the standard and in operative relation to the timing mechanism, a cover on said standard inclosing said date and time indicating unit, means for adjusting the timing mechanism, and means cooperating with the standard and cover for locking said adjusting means against movement.

In testimony whereof, I have signed my name to this specification.

' JOSEPH LEVY.
