ENVELOP lVlOlSTENlNG AND SEALING MACHINE. I

SPECIFICATION forming part of Letters Patent No. 782,058, dated February 7, 1905.

Application filed April 13, 1904. Serial No. 202.983.

T!) (1.71 who/it it may concern:

Be it known that l, BYRON H. ROGERS, a citizen of the United States, residing at atertown, in the county of Jefferson and State of New York, have invented new and useful improvements in Envelop Moistening and Sealing Machines, of which the following is a specitication.

My invention relates to new and useful improvements in machines for automatically moistening and sealing envelops; and its object is to provide a machine of simple and compact construction having means whereby envelops can be automatically fed to a moistening device.

A further object is to provide means forapplying moisture to the gummed surface of the envelop-flap and subsequently pressing said flap upon the body of the envelop.

Another object is to provide laterally-adjustable rollers for moving the envelops successively into position upon the moistcning and sealing devices.

Another object of the invention is to provide means for supplying water continuously to the moistening device.

\Vith the above and other objects in view the invention consists of a bed having a springpressed plunger adapted to force on velops successively into position against guide-arms which are arranged at one end of the bed. Rollers are mounted adjacent the bed and are adapted to engage the envelops successively and move them along the guides, with the flaps thereof extending over one of the guides. By continuously rotating the rollers these flaps are caused to move over the moistened strip of absorbent material, where the gummed surfaces thereof are moistened. The envelops are then brought into position between sealingrollers and are subsequently discharged into a receptacle provided therefor.

The invention also consists of the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which Figure 1 is a side elevation of the machine.

Fig. 2 is a top plan view thereof. Fig. 3 is a section online 3 3, Fig. 1. Fig. 4 is a transverse section online 1 1, Fig. 2. Fig. 5 is a section online 5 5, Fig. 2. Fig. 6 is a plan view of the guide-plate and moistening-pad detached. Fig. 7 is a side elevation thereof. Figs. 8 and 9 are plan views of the top and bottom adjusting mechanisms, respectively, of the envelop-extracting roller; and Fig. 10 is a plan view of a portion of the top plate of the frame of the machine and showing the slots for the adjustable roller.

Referring to the figures by numerals of reference, 1 is a base having aninclined end board 2 at one end and areceptacle 3 at the other end, said receptacle extending from one side of the base and preferably at right angles thereto. 'lhis receptacle is provided with oneadjustable side wall 1, which is connected to the base by means ofbrackets 5, adapted to be secured in adjusted positions bypins 6,

which may be placed in engagement with any one of a series of apertures T.Parallel beads 8 are arranged upon the bottom ofreceptacle 3 and serve to support aplunger 9, having arod 10 extendingtherefrom and through the outer end of the receptacle, said rod being in closed by a spring 11, which holds theplunger 9 normally projected toward the inner end of thereceptacle 3. Said inner end of the receptacle is closed by means of anend wall 12, which is cut away at one end to form anoutlet 13, and projecting into this outletare guidearms 1st and 15, extending from aplate 16. This plate is secured in an upright position upon thebase 1 and in alinement with theend wall 12, and the guide-arm 11 is bent inwardly into theoutlet 13, while thearm 15 is straight. A wicl: 17 or other absorbent material is secured to one face of theplate 16 and is normally contacted by the upper portion of a spring lb, which is secured to the base and is for the purpose hereinafter more fully described. Atop plate 19 is supported above the base andplate 16 bystandards 20, and secured to this top plate is areservoir 21, having an outlet-tube which extends downward to the lower portion of the spring-strip 18 at a point where said strip bears against the lower portion ofwick 17. By providing this arrangement of parts water is continuously supplied to the wick. p

Thebase 1 and thetop plate 19 are provided withslots 23, in which are slidably mounted the necks ofrollers 24 and 25. These rollers are preferably arranged on aline parallel with the sides ofbase 1 and at points between thereceptacle 3 and theend plate 2. Theroller 25 is normally spaced from the plate 16 a short distance, and both of the rollers are held in their normal positions by means ofsprings 26, which are connected tocross-strips 27, in which the roller-necks are journaled, and to thebase 1 andtop plate 19, respectively. Alink 28 is pivoted to thebase 1 and hasashaft 29, journaled in its other end, and to the lower portion of this shaft is secured aroller 30, provided with a series ofpointed projections 31. This roller is normally in position adjacent theoutlet 13. The upper end of theshaft 29 is journaled in one end of alever 31, which is fulcrumed upon the lower face of the top plate and has anapertured arm 32, adapted to receive a locking-pin 33, whereby the lever can be secured in any position to which it may be adjusted. Ashaft 34 is journaled in the base and top plate and directly opposite theroller 25 and at the other side of theplate 16. This shaft has aroller 35 at its lower end. Another roller, 36, is journaled in the base and top plate and is normally contacted by theroller 24. The pass formed between these tworollers 24 and 36 is in alinement with theplate 16. Acrank 37 is secured toshaft 34,

and said shaft is provided withpulleys 38, on'

which are arrangedbelts 39 and 40.Belt 39 extends around apulley 41, arranged at one end ofroller 36, whilebelt 40 extends around apulley 42, secured toshaft 29. A light spring-strip 43 is secured to thebase 1 and extends partly in rear ofroller 24 and is adapted to clamp sealed envelops upon theend plate 2.

Envelops to be moistened and sealed are placed within thereceptacle 3 and in front of i theplunger 9 with the flaps thereof upon the side facing theend wall 12. These envelops are therefore pressed firmly against said end wall by the spring 11, which bears against theplunger 9. As before described, water is supplied to thewick 17 fromtank 21 through thetube 22, and therefore said wick is kept moist at all times. Thecrank 37 is rotated and rotary motion is transmitted therefrom to therollers 30 and 36, as well asroller 35. The projections onroller 30 will contact with that portion of the first envelop which extends over theoutlet 13 and will draw the envelop edgewise through the outlet. As

thearm 14 is curved into the outlet it will promptly assume a position between the body of the envelop and the flap thereof, as shown in Fig. 1, and thelower arm 15 ofplate 16 As the movement of the envelop continues the flap 7 thereof is drawn under the spring-strip 18, which causes it to bear firmly upon thewick 17. Moisture is therefore supplied to the gummed face of the flap. Immediately prior to the release of the envelop from theroller 30 the same is gripped byrollers 36 and 24 and is drawn therebetween. The flap is thus pressed against the body of theenvelop and becomes firmly affixed thereto. Therollers 36 and 24 discharge the envelop against theinclined end plate 2, where it is held by the spring retaining-strip 43. This operation is repeated as long as thecrank 37 is rotated and the supply of envelops is maintained. It will be seen that the envelops can be moistened and sealed at any desired speed. Thesprings 26 allow for a certain amount of lateral movement of therollers 25 and 24, so as to accommodate them to envelops of different thicknesses. Theside wall 4 ofreceptacle 3 can be adjusted laterally, so as to permit envelops of different lengths to be placed within said receptacle.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right tomake such changes as fairly fall within the scope of my invention.
