.Application filed January 27, 1917, Serial No. 144,854. Renewed July 22, 1919. Serial no. 312,577.

To all whom it may concern:

Be it known that I, Bruno A. STREHS, a subject to the Czar of Russia, residing at De troit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Stamp-Affixing Machines; and I do hereby declare the follow- 7 ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a machine for affixing stamps to letters, and the primary object of the invention is to provide amachine which is operated by the operation of a hand lever, for feeding, moistening and aflixing stamps to envelops.

Another object of this invention is to provide a machine as specified which includes a rotary stamp feeding roller for feeding stamps from a roll, over a forarninous surface, beneath which surface is positioned a moistening sponge, to provide a hand lever which has a spring or resilient plate carried thereby for engagement with fingers carried by the stamp feeding wheels for rotating the stamp feeding wheel upon pivotal movement of the hand lever.

A further object of this invention is to provide a series of levers and rods which are connected to the hand lever below its pivot point so that upon the reversestroke or movement of the lever to the stamp feeding roll operating movement, the moistening sponge will be moved upwardly for moisten. ing thegummed surface of a stamp immediately prior to the positioning of a stamp over a letter. I

A still further object of this invention is to provide a plunger structure which has a knife carried by one edge of the same, which knife cuts the stamp free from a strip of stamps, immediately after which it is aflixed to a letter by the downward pressure of the plunger.

With the foregoing and other objects'in view, this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, and claimed:

. In describing the invention in detail, reference will be: had to-the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, in which:

Figure l is a side elevation of the stamp aflix ing machine.

Fig. 2 is alongitudinal section through the stamp afiixing machine showing the lever in a position immediately after operating the stamp feeding roll.

Fig. 3 is a fragmentary view similar to Fig. 2 onlyshowing the lever in a position immediately after it has moved the moistening' sponge upwardly into a stamp engagmg position.

Fig. 4 is a vertical section through the stampa'llixing machine taken at right angles to the section illustrated in Fig. 2.

Referring more particularly to the draw-' ings, 1 designates the main supporting struc ture of the stamp affixingmachineas an'entirety, which structure hasa superposed casing 2 carried thereby in which is mounted a bracket 8. The bracket '3 supports a pin 4, upon which a roll 6 of stamps is mounted. The roll of stamps is preferably formed of a strip of connected stamps as clearly shown in Fig. 2 of the drawings, which are'fed from the roll between the'undersurface of a guiding flange 7 and the upper surface of the top 8 of thesupporting casing 1 by the rotation of a stamp feeding wheel 9. 1 p s The stamp feeding wheel 9 comprises a pair of wheels or rings 10, which are connected by suitable braces 11'. The wheels or rings 10 have hubs 12 which are'rotatably mounted upon a shaft 13. The shaft 13 is supported by suitable bearings 14 within the casing 1. The wheels 9 have a plurality of radiating stamp engaging spurs 14:

slot 18 formed in the casing 1 and is piv ota'lly supported by a pin 19, which pin is carried by a suitable bracket 20 attachedto and extending inwardly from one side of the casing 1. V p f Y The spring plate 16 engages one' of the stop pins 15 so that during the movement of the lever 17 from the position illustrated in Fig. 3,to the position illustrated in Fig. 2, the wheels 9 will be rotated for feeding a single stamp forwardly ever the upper surface of the top 8 and consequently over the foraminous portion 21 of the top 8. A reservoir or tank 22 is positioned directly be neath the foraminous portion 21 of the top 8 and it has a sponge 23 mounted therein which sponge is carried by the upper end of a rod 24. The rod 24 is pivotally con- .nected as shown at 25 to an arm 26, which arm has its lower end connected as shown at 27 to the arm 28 of an angled lever 29. A rod 30 is connected to the angled lever 29, and to the lower end 31 of the hand lever 17, below the pivotal point 19 of the hand lever as clearly shown in Figs. 2 and 3 of the drawings, so that when the hand lever 17 is moved from the position shown in Fig. 2 to the position shown in Fig. 3 the sponge 23 will be forced upwardly in engagement with the under surface of the foraminous portion 21 for moistening the gummed surface of a stamp. A suitable guiding struc ture 33 is formed upon the bottom of the tank 22, limiting the movement of the rod 24.

The casing 1 has a pad 34 carried by its upper surface, outwardly of the foraminous portion 21, which pad may be constructed of rubber or analo ous material and is adapted for holding the etter or envelop to which the stamp is to be afiiXed. The pad 34 has its inner end spaced a short distance from the outer edge of the tank 22 providing a space 32 for receiving the knife blade 33 which is carried by the plunger structure 34 of the device.

The plunger structure generically indicated by the numeral 34 is slidably carried by a bracing arm 35 which curves upwardly and forwardly from the casing 1 and which has a collar 36carried by its upper forward end in which collar is slidably mounted the lunger structure 34'.

A pin 37 extends diametrically through the collar 36 and, through the. slots 38 formed in the sides of the casing 39 of the plunger structure for guiding the vertical movement of the latter. A spring 40 is positioned within the upper portion of the plunger and it has its lowerrend engaging the pin 37, while its upper end engages the inner surface of the top of the casing 39,

. for returnin thecasin to its 11) er osition after it has been forced downwardly by manual pressure The casing 39 has a pad 41 carried by its lower end which is constructed of the same material of which the pad 34 is constructed and which is positioned directly abovethe pad 34 for striking the upper-surface of a letter, and pressing it against the upper surface ofthepad 34 for affixing a; stamp tothe letter, which stamp is severed from the strip of stamps indicated by the numeral 43 which is fed from the roll 6.

dicated in Fig. 2 of the drawings, whichfeeds a stamp forwardly over the forami:

nous portion 21 of the top 8, after which the lever is returned to its normal position or to the position illustrated in Fig. 3 of the drawings, which forces the sponge 23 upvardly for moistening the gummed surface of the stamp. The lever 17 is then pushed forwardly again, which feeds the stamp outwardly over the edge of a letter which is placed upon the pad 34. The stamp having been positioned above the letter, the plungei- 34 is forced downwardly by striking the top of the casing 39 with the palm or ball of the hand of the user, which causes theknife to sever the outermost stamp from the strip of stamps 43, and presses it firmly upon the envelop after which the envelop may be removed from the pad 34 and an un stamped one substituted in. lieu thereof.

The spring plate 16 is constructed so that it will spring over the pin 15 when the lever is moved to its rearward position as clearly shown in Fig. 3 of the drawings.

From the foregoing description taken in connection with the accompanying drawings the advantages of construction and of the method. of operation of the improved stamp aiiixing machine will be readily apparent to those skilled in the art to whichthis invention appertains, and while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit practical conditions provided such, alterations are comprehended within the scope of what is claimed.

WVhat is claimed is:

1. A stamp affixing machine comprising a casing, means carried by said casing for supporting a strip of stamps, a stamp guide upon said casing, feed rollers carried by said casing for feeding the strip of stamps through the guide, a reservoir carried by said casing, foraminous material closing said plying moisture through the foraminou's" material and on the stamps, a letter supporting pad carried by said casing and adapted to receive the stamps from the foraminous covering of the reservoir means for severing the stamps from the strip of stamps and simultaneously applying the stamps to a letter.
