W. YATES. ENVELOP OPENER.
Patented June 28, 1898.
WZZWESSES LITHQ. vasnmav Nrrn WILLIAM YATES, OF RICHMOND, WASHINGTON.
ENVELOP-OPEN ER.
SPECIFICATION forming part of Letters Patent No. 606,261, dated June 28, 1898.
Application filed July 14, 1897.
To all whom; it may concern:
Be it known that 1, WILLIAM Yarns, a citizen of the United States, residing at Richmond, in the county of King and State of Washington, have invented certain new and useful Improvements in Envelop-Openers; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.
This invention relates to new and useful improvements in envelop-openers and it consists in the construction and arrangement of parts, as hereinafter fully set forth, and pointed out particularly in the claim.
The object of the invention is to provide a device for quickly opening sealed envelops, the construction of which is to embrace a bladed plunger and means for regulating the depth of the out, which object is attained by the construction illustrated in the accompanying drawings, in which- Figure 1 is a general perspective view of an envelop-opener as made in accordance with myinvention. Fig. 2 is a central vertical section through Fig. 1, a portion of the plungerspindle being removed.
Referring to the numerals of reference, 1 and 2 designate the side pieces, which have the movable strips 3 6 and the stationary strips 4 5 extending therebetween and are tied by suitable rods 7. 8 represents a platform which extends between said sides 1 and 2, near their front edges, and is rigidly secured thereto. Passing immovably longi tudinally through apertures in strip 6 are screws 9, the inner ends of which are threaded and adapted to screw into strip 5. Securely mounted upon the upper face of said strip 5 is a plate 10, the stationary member of the cutter. It will thus be seen that by turning screws 9 the horizontal adjustment of the plate 10 may be minutely regulated.
11 designates the plunger, which is adapted to be moved vertically in guideways 12, which are formed in the inner faces of said side pieces 1 and 2. Fastened by means of screws or other suitable devices upon the lower angled edge of said plunger is a knife 13, hav
Serial No. 644,508- (No-model.)
in g a spur 14: depending from its lowest point, for apurpose hereinafter referred to, and projecting from the upper edge of said plunger is a spindle 15, which passes through the center of a tie-piece 16. Mounted upon the upper edge of said spindle is a depressing but ton or knob 17, and surrounding said spindle between said knob and tie-piece is a coiled spring 18, said spring having such tension as to exert an upper pressure against said knob sufficient to keep plunger 11 normally in a raised position.
Projecting through strip 3 at the rear of the side pieces are screws 19, (only one of such screws being shown in the drawings,) said screws being held against longitudinal movement through said strips by means of collars 20. The inner ends of said screws are threaded and are adapted to screw into strip 4, whereby its horizontal adjustment may be effected. Mounted upon the upper side of said strip 4 is a guide-plate 21, said plate being rectangular in cross-section.
The operation of opening a sealed envelop is accomplished by passing such envelop horizontally over platform 8 and moving it inward until one end thereof comes in contact with guide-plate 21, when it is held in such position by one hand and the other employed to strike downward upon knob 17 With sufficient force to overcome the tension of spring 18 and carry plunger 11 and blade 13 downward, the arrangement being such that a shearing cut will be efiected.
The purpose of spur 14: is to obviate the liability of blade 13 moving horizontally in the direction of plate 10 when raised there above, in consequence of which it would strike upon the edge thereof in a downward movement and prevent a successful operation.
It will thus be seen that the construction and arrangement of parts hereinbefore set forth produces an envelop-opener that may be cheaply manufactured and is one in which the cutting-blade, as well as the guide-plate, may be quickly and minutely adjusted.
Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-- An envelop-opener, consisting of uprights 1 and 2, strips 3, 6 and 16 extending there the movable strip 5, upon which a cutterplate 10 is mounted, the adj Listing-screw 19 journaled in said strip 3 and screwed into said strip 4, the angled gage-plate mounted upon the upper side of said strip 4, and the parts adapted to be operated, substantially as and for the purpose set forth.
In testimony whereof I affix my signature in presence of two witnesses.
