Title: Apparatus for sealing envelopes and similar papers
IPC: B43M5/02
Filed: 1919-12-08
Abstract: 164,054. Rosenblatt, M. Dec. 8, 1919. Sealing.- Apparatus for sealing envelopes &c. comprises a heating-receptacle for sealing-wax with an indirectly-regulated valve at the lower end, and a pivoted frame bearing a seal whose movement over a moistening-roller and then on to the wax on the envelope is controlled by the sliding of attached pins in slots in the main frame and by two spring-influenced pawls. The double-walled electrically-heated wax receptacle 16, Fig. 1, is carried in a frame 4 and depressed vertically by the knob 8 against the action of the spring 10. To the frame 4 is pivoted at 26. Figs. 1 and 2, an oscillating frame 13 carrying the seal 14 and stud 25. This stud 25 slides in slots 24, 24<a> in the main frame 7 of the apparatus and is controlled by two pawls 27, 28 pivoted on a common axle 29 and connected by the spiral spring 37. The pawl 28 has two notches 32, 33 to engage the nose 34 of a spring-pressed lever 36. When the knob 8 is depressed, the stud 25 slides along the slots 24, 24a whilst the stud 26 slides down the slot 24, thus raising the seal 14 to the moistening-roller 39 and opening the valve 17 at the lower end of the receptacle 16 by means of the wire 18 carrying the valve-plug, the bent lower end 19 of the wire passing through a perforated plug 20 on the frame 13. The stud 25, in passing along the slot 24<a>, bears on the upper end of the pawl 28 and causes the lever 36 to pass from the notch 32 to the notch 33 of the pawl 28. The spring 37 then moves the pawl 27 away from the Slot 24. When sufficient wax has flowed on to the envelope, the knob 8 is released, and the stud 25 returns to the slot 24, the pawl 27 springing temporarily away to allow the passage of the stud along the slot 24<a>. The valve 17 is thus closed and the frame 13 returns to its vertical position. On further pressure of the knob 8, both studs 25, 26 slide down the slot 24, now unobstructed by the pawl 27. The seal 14 is thus pressed down on to the wax on the envelope. The stud 25, in passing down the slot 24, engages the lower end of the pawl 28 and returns the pawls 27, 28 to their normal positions, Fig. 2. On release of the knob 8, the apparatus returns to its original position ready for a fresh sealing operation.
