WILLIAM SIN GLETON, OF VVINOHESTER, KENTUCKY.

DEVICE FOR SEALING AND STAMPING LETTERS AND OTHER MAILABLE MATTER.

SPECIFICATION forming part of Letters Patent No. 418,078, dated December 24, 1889. Application filed September 13, 1888- Serial No. 286,331. (Model-l To aZZ whom it may concern.-

Be it known that 1, WILLIAM SINGLETON, of WVinchester, Clark county, Kentucky, have invented a new and useful Device for Scaling and Stamping Letters and other Mailable Matter, of which the following is a specification.

My invention is a device by which,-after the insertion of the envelope in the machine in its proper place, by one movement of the handle used to operate the device, the said envelope is. stamped, sealed, and ejected, or sealed or stamped and ejected.

In the accompanying drawings, Figure I represents a rear view of my device. Fig. II is an end elevation looking from the right, Fig. I. Fig. III is a section taken on the line III III, Fig. I. Fig. IV is a section taken on the line IV IV, Fig. I, showing the envelope in position to be sealed and stamped. Fig. V is a front elevation showing the envelope in dotted lines. Fig. VI is a detail sectional View taken on the line VI VI, Fig. I. Figs. VII and VIII are views of modifications, Fig. VII being a rear view and Fig. VIII being a transverse section on the line VIII VIII, Fig. VII.

1 represents a frame of wood, brass, iron, or other suitable material, having the standards or pillars 2, 3, 4, 4", 5,6, and 7. The pillars 2 and 7 are provided with tongues or feathers 8 and 9, upon which slides a sliding bar 10. -To the said sliding bar is secured a rod 11, surrounding which rod and bearing against a flange 12 at the bottom of a. cylinder 13 is a spiral spring 14, said cylinder being made integral with or secured to a bracket 14", supported on the pillar 4 at its lower end and secured in an eave or projection 13 at its upper end. The rod 11 is provided with a handle 13 attached to its upper end. A cylinder 15, projecting from said handle and surrounding the upper portion of said rod and spring, playsvertically in the cylinder 13. The plate 17 (whose form is best seen in Fig.1) is adapted for sliding up and down between the pillars 4 and 4. This plate has a projection 19, and bears at its lower end an extension 18, having a foot or lug 20, for purposes hereinafter explained.

At the upper end of the pillar 5 is a fulcrum 21, upon which is fulcrumed an arm or lever 22, which has at one end a bifurcation 23, which receives a pin 24 on the plate 17, while the other end is provided with a bifurcation 25, in which engages a pin 26. The pin 26 is attached to a stamp-inoistener 27, which slides freely between the pillars 6 and 7.

Secured horizontally across the pillars 6 7 on the outside of the moistener 27 is a stampholder 29, provided with a stamp-shaped aperture 30 and the oblong rectangular aperture 31, said apertures being for purposes hereinafter explained.

Cast integrally with the frame are the excavated lugs 32 32, which receive ordinary journal-boxes 33 34, in which are mounted rollers 36 37. Thelugs contain springs 35, which bear upon the boxes 34, and thus keep the rollers 36 37 and their meshing pinions 36 in contact with each other. The roller 36 is an extension of a rod 38, which has a straight groove 39, a spiral groove 40, and a switch 41 at the upper junction of the said straight and spiral grooves, a spring 42 keeping the said switch normally over the entrance of the said straight groove.

From the base of the frame project lugs 43 43, upon which pivots a yoke or bifurcated arm 44, having at its upper end a rectangular stamp-shaped plunger or stamper 45, whose dimensions are but slightly less than those of the aperture 30, and which is provided at one side with a vertically-arranged knife-edge 45, having a shear-cut. the arm 44 receives the lower portion of a rod 47, the upper portion of said rod passing through the upper wall of the yoke. The upper end of the rod 47 carries a cross-bar 48, which is normally pressed up toward the under surface of the die or stamper 45 by a spring 49. The ends of this cross bar, which are flattened or cut away slightly, are adapted, for a purpose hereinafter described, to rest upon the outer ends of posts or stops 49, and thus form a latch for preventing a spring 51, secured to the base of the frame 1, from prematurely forcing the plunger or Stamper 45 inward.

52 is a smooth sheet of metal cast integrally with or attached to the frame, and is about one-fourth the thickness of the pillars.

Lugs 53, 54, 55, and 56, which project from- A cross-piece 46 of the pillars 4, 4, 5, and 6, respectively, are adapted for the reception of a rod 57, to which is attached an envelope supporter and ejector 58 by means of the lugs 59 60 of the said ejector. Surrounding this aforesaid rod is a spring 61, which tends to keep the inner side of the ejector firmly against the standards or pillars, as shown in Figs. III and IV, one end 62 of the spring bearing against the outer side of the ejecior, while the other end 62 bears against the pillar 4. This ejector may be a piece of sheet metal bent into a V- shaped trough, as represented in cross-section. A tooth or plate 64, rigidly attached to the ejector, is capable of engagement with a flexible pawl 65, secured to the plate 17 by means of a screw 63, when the slide-bar 10-is drawn up.

Attached to each end of the slide-bar 10 are springs. 66 66,8which have cams or bent portions 66 and project through slots 67 67 in the pillars 2 and 7 and then upward, having journaled to their upper ends a roller- 68 and causing said roller to press against the face of the smooth sheet 52. This roller consists, preferably, of soft materialsuch as rubber though hard-material may be used. Secured to the base of the frame 1 or at both ends thereof are two upwardly-projecting and inwardly-acting springs 70, each of which has an-inwardly-turned elbow or cam 71 project'- ingthrough slot 67 and bearing against the slide-bar 10. At the upper ends of these springs is supported the envelope-flap moistener 69 by means of vertical sockets 71, in which the extremities of said springs fit, as shown in dotted lines in Fig. II. This moistener consists of a trough or tank having-a longitudinal partition 69, provided with perforations 70 for the passage of water. To one side of the partition the tank is open and filledwith a projecting moistening-cushion 69,composed of an exterior coatingof cotton, an intermediate layer of felt, and an internal filling of sponge or other suitable materials. The tank may be replenished from time to time through the filter-screw 69 The operation of my device is as follows: An envelope Y to be sealed and stamped is placed in the above-described device with its upper edge resting against the smooth flat sheet 52 and its lower edge against the bottom of the ejector, whenthe flap z will be resting upon the wet cushion 69 of moistener 69, which, in combination with the inclination of the inner side of the ejector, will cause said upper edge to bear against the sheet 52. A little water-just enough to dampen the sponges-is put into the moisten-' ers, and the end of a strip of stamps of the usual number-viz., tenis inserted into the end of the stamp-holder 29 and forced along until it comes between the stamp-rollers 36 37. The operator then, by pressing upon the handle 13 presses the cylinder 15 down into the cylinder 13. The described motion of the handle causes the slide-bar also to descend, which carries with it the camsprings 66 66, thereby causing-the roller 68 to descend. In the initial movement the bar 10 moves below the elbows 71 on the springs 70, and thus permits said springs to carry the flap-moistener 69 inward toward the envelope, thus causing the rollers 68 to press the flap against the cushion 69 with considerable force, whereby the gum on said flap is moistened; but before the moistener 69 moves inward far enough to obstruct the descent of the roller the cams or bends 66of the springs 66 come in contact with projections 4 on the springs 70, and thus the latter are forced back again, carrying the flap-moistener to its usual position and out of the path of the descending roller 68. Theroller. in its descent drags the flap of the envelope past the cushion 69and presses it against the envelope, thereby causing the moistened gum to adhere. The roller after going completely beyond the flap returns upon the release of the handle, thereby running twice over said flap. The downward motion of'the handles also causes the slide-bar 10 to press (when near the limit of its downward journey) against the foot or lug 20, thereby causing the plate 18 to descend, which will cause the pin 24 to operate the armor lever 22, and hence to elevate the stamp-moistener 27, causingthe latter to dragits damp sponge 27, which, when in the lower-position, projects through the plate 52 and bears against thecorner of the envelope, across a portion of the envelope, whilethe roller 68 is bearing upon the opposite side, thus dampening such, portion tocause the adhesion of the gummed stamp. The slide-bar, in descending causes the stud 73 on the end of the slide-bar to run in the spiralgroove etO of the rod'38. This spiral groove is so out that thetraveling of the stud73 therein will cause the said rod to make one revolution, thereby causing the rollers 36 37 to also make but one revolution, and such rollers being of the proper size the row of stamps will: bermoved sufficiently to feed a single stamp over the stamp-shaped aperture 30, the stamps being guided and held in the stamp-holder by the overhanging flanges 74 74. The motion of the said roller is just sufficient to allow the edges of the stamp to coincide withthe edges of the said aperture, so that the knife-edge 45 of the stamp-plunger will sever the same at the perforations. The slide-bar near the limit of its descent presses upon a trigger 75 of the rod 47, thereby drawing the cross-bar 48 oif the lugs 50 50 and releasing the stamp-plunger. The latter, being now unbound, is forced down through the aperture 30 by the spring 51, thereby cutting off a stamp and pressing it against the moist corner of the envelope. After, the slide-bar 10 has completed its descent and the envelope has been scaled and the stamp pressed in its place, the bar is forced up by the pressure-of the spring 1 1 against the handle 13, carrying with it the roller 68, which again passing over the en- IIO velope presses the latter firmly against the stamp While the plunger 45 is yet in its normal position. The bar in its descent causes the stud 7 3 .to travel up the straight groove 39 of the rod 38. WVhen the said stud arrives at the upper junction of the straight and spiral grooves, it trips or forces the switch 41 upward and passes the same,when the switch will immediately regain its position over the straight groove by the action of the spring42. The stud being compelled to rise in the straight and vertical groove, it will be understood that the bar 38 will not be again revolved, and hence the stamp-feeding rollers 36 37 are permitted to remain at rest and hold the strip of stamps in position for the succeeding down ward' movement. \Vhen the slidebar has about half completed its ascent, a roller '44, journaled in its upper side, comes in contact with the inwardly-curved front surface of the yoke 44, which, acting as a cam, forces the stamper or plunger 45 out of the aperture 30. When the rod 48 comes to the rear ends of the lugs 50 50, it is immediately forced to its original position against the said ends of the lugs by the pressure of the spring 49. When the slide-bar is still nearer home and the roller 68 at the upper edge of the envelope, it comes in contact with the projection 19'of the plate 18, thereby forcing the said plate upward, which will bring the tripper or pawl up under and in contact with the tooth 64 of the ejector, thus tilting the latter against the action of the spring 61 and throwing the envelope out upon the table. The tripper being of spring metal and its engaging-shoulder being somewhat rounded, the tooth 64 will disengage after the pawl or tripper has risen sufficiently far to throw out the envelope. When the tripper has passed said tooth, the ejector will regain its normal position by the action of the springs 61. When the slide-bar has nearly completed its upward movement, it will cause the pin 24 to bear against the upper side of the indentation 23 of the arm 22, which will operate to throw the stampmoistener 2-7 back'into its original and lower position.

Instead of using the above-described means for moistening the flaps and the stamp and for stamping the stamps on the envelope I may employ the following means, viz: In the place of the above-described flap-moistener I may use a roller 76, (see Fig. VIII,) whose lower surface revolves beneath the surface of the water in the tank or reservoir, and whose upper surface is exposed, so that the flap of the envelope may come in contact therewith, thereby revolving the roller and at the same time causing said roller to moisten said flap. The stamp-moistener in this instance, however, is stationary, it being secured in any suitable manner to the main frame 1.

For a stamp-moistener I may substitute for the above-described device an arm 78, f ulcrumed on the pillar 3, and being attached to one end of the stamp-moistener '79, operating from beneath instead of above, as before, (this form of stamp-moistener not being used, however, with this form of stamper,)

and to the other end a pawl 80, which is aside by theslide-bar and the moistener immediately regain its position by action of the spring 81, attached to the frame 1 and said arm 78. These stamp-moisteners may be so constructed as to moisten the envelope or the stamp, or both, but preferably the envelope. WVhen they are constructed to moisten both stamp and envelope, a portion of the rear walls of the box carrying the sponge is removed, which will expose the sponge or moistener bothin front and behind.

Instead of the above-described preferred form of stamper I may employ a stamper of the following construction:

Instead of having the yoke 44 fulcrumed upon the frame, as before, it may be fulcrumed upon the sliding bar 10. (See Figs. VII and VIII.)

In place of the plunger 45, I may use a metallic box 82, open at both ends and having its internal dimensions slightly less than the dimensions of a stamp, in order that the stamps may fit snugly within the said metallic box. This box has cast to its rear end standards 83 84 85 86 87. The standard 83 receives a rod 88, which is rigidly attached to a follower 89, which is caused to bear against the stamps (which are inserted immediately in front of said followers) by the spring 90. The pillars 6 and 7 have identically similar indentations 91 and grooves or notches 92, which receive identically similar teeth 93 upon the front of the yoke 44. \Vhen the slide-bar is up, the teeth are engaged with indentations 91 and the box is resting upon the sponge of the moistener between pillars 6 and 7. WVhen the sliding bar has descended acertain distance and the said descent disengaged the teeth from the said indentations, the teeth come to notches 92, into which they are forced by the springs 51. A stamp is thereby stamped upon the envelope, and the teeth, continuing their descent in said notches, operate to draw the remaining stamps down over the said stamp, thereby more effectually securing said stamp. A pawl 94, pivoted upon the end of the sliding bar 10, having an inclined surface 95, is forced in front of the arm or yoke 44 (thereby disengaging the said arm from the notches) by its curved lower surface coming in contact with the floor of the frame. The sliding bar may be drawn up without the danger of the teeth catching in any of the said notches or indentations. When the sliding bar is IIO home, a projection 96 of the frame operates to trip said pawl 94, thereby releasing said pawl from the front of the arm 44 and allowing the spring 51 to force the stamper down upon the sponge preparatory to another operation. The ejector in this form is also modified, it being composed ofa wire bent into an undulate form. Some of the undula tions of one side are elongated, as at 97, and passed through the loops or undulations of the other side, thus securing the lower edge of the two sides together and forming a trough or basket V shape in cross-section. The ejector is mounted on the rod 57 by means of the lugs or projections 59 60, as in the other form, which, however, in this instance are provided with plates or arms 98, secured to the wires of the ejector inv any suitable manner, the lugs 59 60 being alike, but only one being shown.

The roller 68 is attached to the sliding bar 10 by means of the springs 66, as in the first form; but in this instance such springs do not have the cams or bends 66, as the flapmoistener is stationary.
