HENRY A. THEXTON, OF sT. THOMAS, NORTH DAKOTA.

, ENVELOP MOISTENER AND SEALER.

SPECIFICATION forming part of Letters Patent 0. 611,873, dated October 4, 1898. Application filed January 16, 1898. Serial No. 666,747. (No model.)

To all whom, it may concern.-

Be it known that I, HENRY A. THEXTON, of St. Thomas, in the county of Pembiua and State of North Dakota, have invented a-new and Improved Envelop Moistener and Sealer, of which the following is afull, clear, and exact description.

This invention relates to machines for moistening and sealing envelops; and the object is to provide a machine of this character that shall be comparatively simple in its construction and operation and with which successive envelops may be rapidly moistened and sealed.

I will describe a machine embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a section through the line 1 1 of Fig. 2 of a machine embodying my invention. Fig. 2 is a section through the line 2 2 of Fig. 1, and Fig. 3 is a section through the line 3 3 of Fig. 1.

Referring to the drawings, 1 designates the base of the machine-casing, on which are socured the side pieces 2, having a removable cover 3. Having journal-bearings in the side pieces are alower feed-roller i and alower discharge-roller 5. Ooactin g with the dischargeroller 5 is an upper discharge-roller 6, having its journal-bearings in blocks 7, moving vertically between guides 8, and the roller 6 is held yieldingly with relation to the roller 5 by means of springs bearing upon the blocks 7.

Above the roller at is a roller consisting of a feed-section 9 and a moistener-section 10. This roller has its journal-bearings in blocks 11, movable vertically between guides 12 and held yieldingly by springs 13, bearing upon the blocks. The rollers 4, 5, 6, and 9 have a covering of rubber to provide elasticity and an outer covering of felt or similar material to absorb any moisture that may be upon an envelop. The rollers 4 and 5 are connected by a belt 14, so as to rotate one from the other, and one of these rollers (here shown as the roller 4.) has a crank 15 on its extended journal, by means of which the rollers may be turned; but, if desired, a band or other wheel maybe substituted for the crank and the rollers operated by a suitable motor.

The moistening-section 10 is conical, with the smaller end toward the section 9, and be Secured between the side pieces 2, forward of the feed-rollers, is a platform 18, and this platform has an extension 19 between the feed and discharge rollers. At one side of the platform is a guide-strip 20, against which one edge of an envelop engages to guide it between the rollers.

In operation the envelop to be sealed is placed upon the platform 18, as indicated in Fig. 2, and then pushed forward with the flap projected overthe reservoir 16. The rollers 4 and 9 will feed the envelop along, and the roller-section 10 will press the gummed por-' tion on the wicking 17, and the rollers 5 and 6 will close and press the flap down on the body and discharge the sealed envelop. As the upper rollers yield vertically, it is obvious that the thickness of the contents of the envelop will be immaterial.

Whilethe discharge-rollers are of importance, they are not absolutely essential, as it is obvious that the envelops may be discharged directly from the feed-rollers.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An envelop moistener and sealer, comprising a casing, a feed-roller mounted therein, a roller above the feed-roller, consisting of a feeding-section, and a conical moistenersection, and a stationary moistening'device below the conical section, and against which the envelop-flap is pressed by the conical section, substantially as specified.

2. An envelop moistener and sealer, comprising a casing, a pair of feed-rollers in the casin g, the upper one of said feed-rollers havinclined downward and forward, substantially as specified.

4. An envelop moistener and sealer, comprising a casing, a platform in the casing, a pair of feed-rollers, the upper one of said feedrollers having a conical section, a Water-reservoir having an inclined top and an opening therein for a moistening material, and discharge-rollers, substantially as specified.

HENRY A. TI-IEXTON.
