STAMP-HANDLING MACHINE.

Specication of Letters Patent.

Application tiled. January 21, 1911. Serial No. 603,839.

To all whomr -1' t may con ccm Be it known that I, Josmn J 011x SCHER- uicit, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Stamp-Handling Machines, and declare the following t-o be a full, clear, and exact description of the same, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to postage stamp handling machines, and has for its object an improved device of this type by whose use the services of a clerk may be dispensed with in the vending of small quantitles of postage stamps, such as' small retail storekee ers are called upon to do to such an uncom ortable extent, and whereby the gummed surface of the stamps is kept clean and sanitary until the individual stamps are delivered to the purchaser. The stamps sold are fed from a roll, such as is now furnished by the postal authorities, in a sealed package if desired, and the mechanism, in addition to including means for guiding and selecting a valid coin, include means, which can be rendered operative only by the presence of thc coin, whereby the stamp or strip-.actuating elements may be brought into operation. The stamp advancing and severing mechanism is, however, capable of use, with slight modifications of structure, in such other devices as stamp-aiiixing machines, and I therefore do not restrictmyself to its use with coin-.controlled mechanism, but merely choose this type of mechanism as, in this instance, illustrative of one of the uses to which my invention can be put.

In the drawings :-Figure 1, is a perspective of the completed device.- Fig.- 2, 1s a side elevation, largely in sect-ion, of the interior of the case and cash drawer. is a side elevation of the case, similar to Fig. Q, except for the fact that the irregularly shaped plate, which constitutes part of the coin runway, is removed to expose to view other parts of the mechanism immediately in the rear thereof, as viewed from one side of the casing. Fig. 4, is a reverse side elevat-ion (looking in the opposite direction from that ofFigs. 2 and 3) of the stamp handling mechanism, disassociated from the casing. Fig. 5, is a perspective of the locking lever.

Fig. 6, is a detail of the coin runway plate, there being both a side and an end vicvv thereof. Fig. 7, is a section through the stamp-feeding device, the same being in initial feeding position. Fig. 8, is a section through the stamp-feeding device, after it has acted, showing a stamp ready to tear ofi. Fig. 9, is a view of the stamp feeding mechanism at right angles to that of Fig. 8, and facing toward the front of the casing. Fig. 10, is a plan view of the stamp-feeding mechanism shown in Figs. 7 and 8. Fig. 11, is a detail perspective ofthe plate for holding the stamps in their delivery trough, and of the locking bar therefor. Figs. 1Q, 13 and 14 are details of the two sides and of thc coin-receiving edge of the controlling wheel, into which the coin passes fronrthe inlet` chute. Fig. 15, is a perspective of the operating shaft, the parts which carry the stamp being spaced to an exaggerated degree for they purpose of clear illustration. Fig. 16, is a perspective of the concaved lever which actuates certain of the stamp-handling parts.

A represents the base of the machine, upon which rest the parts B and C of the casing. Of these, the part B is preferably fixed thereto, and the part C, which preferably constitutes one side' and the rear of the casing, is detachably secured thereto by means of interlocking lugs and a keycontrolled latch. Preferably, though not necessarily, the parts of the mechanism contained in the casing are-.assembled as a removable unit and mounted by means of a single bolt or screw 9 upon the side wall of one of these parts, preferably the part B, so that, without disassembling the organized mechanism, it can, when desired, be removed in its entirety from the case by unscrewing the supporting screw. In the side wall C there is provided an inspection nWindow E, past which, as will be hereinafter explained, the coins not primarily reectedby the coin-handling mechanism,

pass, and are for a time halted on their way to the cash drawer D, vso that they are thus availablefor inspection. v

The tablet F in the front of the casing may be used for purposes 'of advertising, lor information' as to the character and method of operation of the machine, the first step in lthe operation of i lwhich consists in the insertion of a coin of the denomination specitied by thedirections on the tablet, in the slot G. If the coin is a proper and genuine one, it passes the magnet M, but if it be a steel or iron slu it is turned aside thereby sufficiently to .1e turned into the track of the slug runway H, through whose delivery end Q, it is promptly returned to the would-be cheater of the machine. If, however, it is a proper coin (and for the purposes of the further description of this speclfcation a nickel will be chosen fc-r illustration, and it will be assumed that the machine is intended tosell two two-cent stamps for five cents) or if the slug used be a brass one of the exact size of a nickel, and therefore unaffected by the magnet, it passes on down the runway K until it strikes the mutilated periphery of the coin-controlling wheel L, into the cutaway portion of which J it falls, with its mass partly within and partly without the true periphery of the wheel L. This wheel L is one of several elements that is mounted upon the shaft N, whose right-hand end extends outside the casing, and carries the actuating crank or lever P. On one face of the wheel L are carried a pair of projections 16 and 17 between which an integral knob 19 on the lever 22 may engage. By this means the machine, when not in use, is kept in such position, as to its interior parts, that when a nickel is dropped in the slot the wheel L will be in proper registering position to receive it in its coin-receiving part J. W'ith the coin in this position, the lever P is now turned so as to swing the wheel L until the coin which it carries engages the laterally projecting pin 32 on the lever 22, rockinrr it to the degree necessary to allow the coin which has been used to effect the third precedin actuationto fall from the delivery end o the runway R past the pin 21 on the lever 22 into the cash drawer D. Further rotation ofA` the shaft N by means of the lever P turns the wheel to such an extent that the new coin now drops from its seat in the wheel into the chute R, which inclines somewhat downwardly, but whose delivery end is controlled bythe pin 21 on the end of the lever 22. This lever is not mounted upon the shaft N, but is pivoted v upon the pin or screw 23, which is located about on a level with the shaft N, and somewhat to the rear thereof. This lever is yieldingly held in such position that the pin 21 temporarily closes the end of the coin chute R, against the fall of the coin therefrom, being yieldin ly held in such position A by means of the spring 24, which is attached to the upper pin 25, the spring being anchored to the projection 26, which lies closely under the tablet F of the outer casing of the machine.

By the turning of the coin-controlling wheel L sufficiently to thus drop the nickel into the chute R, the cam 27, which is ixedly carried on the shaft N, has been turned to such a degree as to turn its flat or cut-away -side 28 away from the concaved side of the lever 29, the curved and truly circular face 27a of the cam being of such size as to slightly engage the point 30 on the lever 29 and thereby actuate the lever which is pivoted, not on the shaft N, but on the rod 35, which is located about on the level of the shaft N, but nearer the forward' face of the casing. As the shaft continues to revolve, carrylng the wheel L with it, its periphery being as shown partly in Figs. 12, 14and 15, not truly circular, engages with its projecting coin against the pin 32 on the lever 22, resulting, as above explained, in depressing the lower end of the lever to effect the release of the coin past the pin 21, at the end of the chute R. As herelnafter explained, as soon as the coin is released, the lever drops back to its original position under the pull of the spring24, the coin nearest the end of the chute dropping into the coin drawer D.

Projecting laterally (toward t-he righthand side of the casing) from the lever 29 is the hoistin bar 33, which passes under the elbows o the several thin lingers 34, which are pivotally supported from the bar 35, being yieldingly held with their lower points 36 in lowered position by the pull of the individual springs 37, which are anchored to the bar 38.

The shelf T extends toward the front of the casing and is supported under the strip of stamps unwinding from the roll S which is supported upon the pin 39 on the righthand side wall of the casing. Slidably engaging thereon is the fiat pressure plate W,

which is of sufiicient breadth to extend completely over the stamps from one side of the strip to the other. The forward end of this flat pressure plate is divided into a number of guards 40, between which extend the lower points 36 of the fingers 34, which are guarded and, to a degree, grouped thereby. By means of the spring 41, which engages under the shoulder 53, the forward end of the tray W is kept resiliently pressed against the stamps which are passing between 1t and the upper surface of the shelf T, whose forward end 54 immediately under the lower tips 36 of the perforation levers is preferably very slightly cut away or troughed (see Figs. 7 and 8), in order to permit the points as they dro as hereinbefore explained, to reach su ciently below the surface along which the strip of stamps is travcling to insure the passage of som'e of these points through some of the perforations between the stamps, thus causing the severance of the strip at this end when the outer ejected end of the strip of stamps which projects through the aperture Z in the casing is pulled upon by the purchaser. When the device is not in use, and in fact when it is being actuated as to the handling of the coin, these fingers 34 are held in lowered position by the pull of their springs 37, thus preventing improper and unauthorized access to the interior of the stamp slide for the purpose of withdrawing stampsfor which the user has not paid.

Mounted upon the shaft-N, directly above the central portion of the shelf T, is a milled roller 42, of such radial extent as `to engage through the cut-away central portion 4G of the flat pressure plate W against the surface of the strip of stamps which is being fed along the top of the shelf T. Pivotally supported below the shelf T by the pin 43. 1s a reek arm 44, in Whose upper end 1s journaled the lower milled roller 45, which projects into a cnt-away por-tion 46 of the shelf immediately below the adjacent peripheral portion of the upper milled roller 42, the rock arm 44 being yieldingly held in its position by means of the spring 47.

The peripheral extent of thelarge milled roller 42 is such as to cause, in the one rotation which -is imparted by the actuation of the mechanism to the intended degree, the projection or travel of the strip of stamps along the shelf T to the degree necessary to forwardly project two stamps, preferably leaving the line of perforation separating the-second and third stamp approximately beneath, though somewhat in the rear of, the lower points 36 of the finger 34, thus requiring that the stamps be slightly further withdrawn by manual pull on their projecting portion before the points 36, which have first encountered the unperforated surface of the second stamp, can reach and fall into the perforations.

On the shaft N, at one side of the large milled roller 42, is carried the cam tooth 50, which, as the shaft rotates, engages against the top branch 51 of the rock arm 44, forcing it down, and thus moving the lower milled roller 45 away from its contact With the under face of the stamps, contemporaneously with the end of the forward movement of the stamp strip, and with the drop into the perforations between the second and third stamp of the points 36 of the fingers 34. Atthie time the plane or straight face 28 of the'cam 27 engages against the lower end 30 of the lever 29, rocking it against the pull o-f its spring 29EL away from contact with the shoulder 48 on the rock arm 44. This occurs at the end of the forwardly feeding movement, and as a part of this movement the hoisting bar 33 is dropped down, permitting-the perforation levers to drop accordingly onto the surface of the stamp strip slightly forward of the line of perforations between the second and third stamps. This anchors the strip' of stamps against further and unauthorized movement, and insures the severance at the desired point of the two stamps, whose sale is intended at the desired point. -T he presence of the guards 40 at the forward end of the pressure plate W immediately above the rear end of the stamps whose severance is to be etl'eeted, as well as above the forward end of the remaining portion of the strip (the forward stamp of the pair next to be ejected), insures the impossibility of inserting a wire or knife through the opening Z in order to prevent the dropping of or to raise, the ingers 34, which prevent the drawing out of more than the two stamps whose sale is intended at a single operation of the device; and the entire independence of one another of the several perforation levers 34, whose thickness is merely that of sheet metal, insures that, regardless of any possible irregularity in the position of the perforations across the stamp strip, some, at least, of the holding points 36 will descend into the pcrforations, and lock the strip against unintended pulling out. Then the rotation of the shaft N- has progressed to such a degree (the cam 27 of course moving accordingly), as to permit the release of the arm 44, which rises again under the influence of the spring 47, so that the lower milled roller 45 engages against the under face of the stamp strip, the rise of the lever 29 causes the hoisting bar 33 to raise the lingers 34, so that their lower points 36 no longer interfere with the forward progress of the vstamp strip toward the delivery aperture. In this position they remain only until the two stamps whoseisale is desired are fed forward by the rollers, after which they again drop to closure position with respect to the stamp runway, because of the drop of the hoisting bar 33. The next actuation e-f the machine, beginning with the insertion of the coin, and in due course the rotation of the upper milled roller 42, again projects another two stamps to position where they may be drawn out after the perforation levers have been dropped sutliciently to enable their holding points to again engage in the perforations between the then second and third stamps on the strip.

It is evident that, and proportions of the several parts, such as the milled feed roller, and the coin-handling mechanism, this device can be adapted or constructed in the first instance for other sales combinations, such as five one cent stamps for a nickel, or five two cent stamps for a dime, etc.. without departing from the proper scope of this disclosure. 4

The striking of the surface of the stamps by the perforation points 3G just forward of the line of perforations between the second andthird stamp in the strip, thus requiring the slight further movement of the strip by variations in size before severance, bymauual pull, constitutes a'valuable means of readjustin the various vin the exact width of the stamps in various parts of the roll, which, though slight and only occasional, are not wholly unavoidable.
