ENVELOPE MOISTENER AND SEALER.

SPECIFICATION forming part of Letters Patent No. 465,498, dated December 22, 1891.

Application filed March 25, 1890.

To all whom it may concern.'

Be it known that I, ELIsHA RYDER, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Envelope Moisteners and Sealers, of which the following is a full, clear, and exact description, whereby any one' skilled in the art can make and use the same.

The object of my invention is to provide a device by means of which an envelope may be moistened for the purpose of aflixing a stamp, and may-also have its fiap not only moistened, but sealed by the same device.

To this end my invention consists in the details of the moistening and folding device and in their combination, as more particularly hereinafter described, and pointed out in the claims. i

Referring to the drawings, Figure l is a top or plan view of one form of the moistener and sealing device. Fig. 2 is a view in front elevation of the same. Fig. 3 is a detail view, in cross-section, ofthe folder on plane denoted by line x of Fig. 1. Fig. 4. is a detail view,- in cross-section, of the folder on line y y of Fig. 2. Fig. 5 is a detail view, in cross-section, of the sealer on line z z of Fig. l.

In the accompanying drawings, the letter a denotes the reservoir or tank adapted to hold water, and this vessel may beof any convenient material, as of iron, copper, glass, or porcelain Ware. At one end of the vessel there is arranged an outlet b, leading from the top of the vessel and curving downward, so that the outer end of the tube (the outlet is tubular both where it passes through the top of the reservoir and at the outer end) is arranged at the'proper distance above the table a', formed on the top of the reservoir, to enable the end of the wick or other like moistening device to be set a properdistance from the table to moisten anything that is inserted below the end of the tube. The lnoistenin g device is preferably made of a fiat wick, such as is used in an ordinary lamp, and I have found the best results to follow from the use of two wicks that are stitched together along the center, making what may be called a compound feed device. One end of the feed device is located within the water in the reservoir, while the other end is turned downward and looks toward the top Serial No. 345,201. (No model.)

of ther table, preferably near the right-hand end; but this end e of the wick or other feeder is preferably located above the level of the surface of the water in the reservoir, in order that it may not serve as a siphou and carry so much water as to cause it to drop from the end of the feeder. Located as described the feeder absorbs and conveys just enough water to keep the Working end of the feeder in a moist condition, the tube being preferably covered in from end to end to prevent evaporation, and being also provided near the working end with a feed-'screw d.

An envelope or other paper is moistened by introducing it edgewise underneath the feeder, from which a certain amount of moisture is wiped upon the paper, and an envelope may be thus moistened for the purpose of affiXing-the stamp.

In order to use the device for moistening and sealing an envelope, the envelope is introduced below the feeder from the right with the flap bent, as illustrated in dot-ted outline in Fig. 1, and then is slid toward the left until it encounters the wall of the folder f, that V is an extension of the guide lg--that is, a vertical wall arranged along the top of the reservoir to serve as a guide as well as support for the folder. The folder is wide and curved transversely toward its mouth, but narrows rapidly toward vthe farther end, so that the flap of the envelope is gradually turned down, as illustrated in Figs. 3, 4, and 5. The folder terminates in a flat spring-arm forming the sealer h, the outer end of the arm resting with a yielding pressure upon the end of the table a', so that the sealer is adapted for use on envelopes of varying thicknesses. As the envelope is slid progressively from the righthand end to the left-hand end of the device in the manner above described, an opened envelope is first moistened, then folded over, and finally thoroughly sealed by a single movement of the envelope across the table of the device. The lower corner of the guide is preferably rounded, as at g in order to properly start the folding process.

In many forms of feed devices that have been tested the compound feeder, consisting of the two wicks laid iiatwise upon one another and fastened together by stitching, (usually along the centen) has given the best IOO results; but I do not limit myself to this specific form of feed device for conveying the water by capillary attraction from the reservoir to the working end of the feeder, as other absorbent fibrous fabrics may be used Without departing from my invention.

To aid in the sealing of a long envelope the front edge of the sealer maybe turned up, as shown in dotted lines in Fig. 2..

I claim as my inventionl. In combination With a reservoir a, an outlet through the top thereof, a curved support for a flbrousinoistener secured adjacent to the opening and provided With a feed device, the moistenerfeed device, and the fibrous mostener extending from Within the reservoir and with its delivery end located above the possible level of the Water in the reservoir, terminating near the surface of th-etop fof the reservoir in a position accessible forthe specilic use described.

2. In combination With a reservoir Ct, an outlet through the topthereof, a curved support b for a fibrous moisteuer c adjacent to the opening and provided with a feed device d, the moistener consisting of two or more Wicks superimposed and fastened together-With one end Within the reservoir and the otherthe delivery end-located above the possible levelv of the Water in the reservoir and nearandoverlying the surface of the top of the reservoir in a position accessible for the specic use, all substantially as described.

3. In combination with areservoir for water or like fluid, the moistener consisting of a bent tube leading from the top of the'reser- Voir and with the other end terminating near the top of the reservoir7 the fibrous feeder lo# f cated Within the tube and forming a moistener device, and the folder locatedon the top of the reservoir and terminating in a spring sealing device, all substantially as described.

4. In a device .for moistening and sealing letters, the fibrous moistener located at one end of the reservoir with the delivery end of the moistener overlying the table formed by 1 the top of the reservoir, the folderlocated adjacent to the moistener and terminating in a sealer, consisting of a dat spring-arm, overlyingthe-top of the reservoir and having an opening between it and the surface less than the thickness of the object intended to be slid beneath it, all substantially as described.

5. In a device for inoistening` and sealing letters, the combination of the reservoir, the

tubular outlet with a deliveryend` terminating near -the surface ofv the reservoir, lthe fibrous feeder located within the tube, the guard'located `onfithe top of the reservoir, the folder forming va continuation of the guard, and the vspring sealing device located beyond .the folder, all substantially as described.

6. In a device forinoistening and sealing letters, a table, a porous and absorbent Waterretaining element slocated at one end of the table and closely overlyingit, whereby a narrow passage -is-leftbetween it and theftable, the guard located beyond the moistener and leading into a folder that terminates iu al sealing-arm that' is adapted to hold with a yielding pressure an object slid beneath it, all substantially as described.
