This invention relates toa device forl cutting olf a small portion at the` end of an envelope 1n the kopening thereof to gain-access to thecont'ents and suppliesan article l which is bothornamental and adapted for use as a paper weight.
The invention also provides a device ofthe nature aforesaid embodying a few number of parts, and including -a cuttingmechanism comprising blades and means yieldably pressing the blades together to yinsure their positive actionl at all times inthey lopening of a letter or lthe cutting of paper or terial betweenthe blades. y
While the drawings illustrate a preferred embodiment of the invention, it is tofbe understood that in'` adapting the means to meet specific needs and requirements, Vthe other madesign may be varied and such other changes. in the minor details ofconstruction may bev resorted to within the scope of the invention as claimed,
without departing from the spirit thereof. f'
l For a. full understanding of the invention and the merits thereof, reference is to vbe had tothe following descriptionand the drawings hereto attached, in whicli,-.A a A v2igure 1 is a perspective v-iew of aletter opener embodying the invention.
Figure 2 is a vertical longitudinal sectionaly view of the device.
Figure 3 is a vertical transversesec'tional view on the line 3-3 of Figure 2, looking to the left as designated by the arrows.v
Figure 1 is a view similar to Figure taken on the line 4-4 of Figure 2, looking to the right, as indicated by the arrows.
Corresponding and like arts are referred to in the following description and designated in the several views of by like reference characters.
The device comprisesa hollow body or casing 10, which is elongated and open at the bottom and front, said casingV preferably consisting vof a casting, which is oblong, orr
elongated and formed centrally of the top with an lopening from which ldepends a boss 11, in which is mounted a. stem 12. Aknob f or head 13 surmounts the upper `projecting lend of the stem 12 and the latter has a slot 14 formed in its lower end to' receive the upper portion of a pivoted blade 15 and a roller 16 which is mounted upon a pin 17, whose ends project to engage the lower end of the boss 11 and thereby limit the upward movement of the stem 12. The pin 17 thus the drawings forms an axis for the roller 16 and stops to Vlinut the upwardmovement of the stem and prevent its displacement.
