UNITED STATES PATENT Fricn.

DAVID XV. SHOLES, OF HAMPSHIRE, ILLINOIS, ASSIGNOR TO IIIMSELF AND CHARLES H. BAOKUS, OF SAME PLACE.

ENvELoPE-OPENER.

SPECIFICATION forming part of Letters Patent No. 425,587, dated April 15, 1890. Application filed March 2l, 1889. Serial No. 304,117. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, DAVID YV. SHOLES, a citizen of the United States, residing at Hampshire, in the county of Kane and State ot' Illi- 5 nois, have invented a new and useful Improvement in EnvelopeOpeners, of which the following is a specification.

My invention relates to devices for opening envelopes.

The object of vmy invention is to provide an envelope-opener of a simple, efficient, and durable construction, by means of which a narrow strip may be severed from the extreme end or edge of the envelope without danger or possibility of cutting or marring the contents of the envelope, and which will operate rapidly and with ease and convenience.

My invention consists in the novel devices and novel combinations of parts or devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which form a part of this specication, and in which similar letters of reference indicate like parts in all the figures, Figure 1 is a side elevation of a device embodying my invention. Fig. 2 is a centra-l vertical longitudinal section, and Fig. 3 is a front view.

In said drawings, A represents the baseblock, to which the frame Bis secured by screws o. The frame Bis furnished with upright standards Z), to which the stationary shear or knife C is secured by screws c. The face of the knife or shear C tits against 'adjusting-screws c, by means of which the cutting-edge of the knife maybe adjusted, so as to properly co-operate with the movable knife D. One of the standards b is or may be made somewhat longer than the other, as the knife C is set at a slight inclination, so as to give a shearing cut. This is clearly shown in Fig. 3.

rlhe movable knife D is fixed on the end face of a lever or pivoted frame F, to which the table-plate G is attached by screws g. The lever-frame F has a shoulder or recess f at its end, on or in which the shear D is secured by screws d, which are countersunk in the shear D, so as to be flush with the face thereof and not strike the edge of the stationary shear C. The frame or lever F is hinged or pivoted by a bolt or pin f to the upright standards b on the main frame B. A spring l-I, secured to the frame B and bearing against the envelope-supporting plate G, serves to retract the movable shear after each cut.

The envelope-supporting plate or table G is furnished with an upwardly projecting guide flange or lip g at one side to properly 6o guide the envelope.

K is the gage, against which the end ot the envelopes abut, and by which the width of the paper strip cut from the end of the envelope by the shears is regulated. This gage K is provided with flanges or lips le 7;, through which screws k pass to secure it in place on the frame B at. the end or mouth of the table or chute G, upon which the envelopes rest. This gage K preferably consists of a piece of 7o sheet or plate metal, and it is adjusted in respect to the knife D, so that only a narrow edge of the envelope can project over the upper edge of the knife or sb ear D.

To open an envelope all that is necessary is to lay it on the inclined plate G and press down on the end of the plate, thus rotating the knife D about its pivot f', and thus cutting ott a very narrow strip from the end of the envelope. The gage K prevents any in- 8o jury to the contents of the envelope and insures the cutting of a uniform narrow strip from the envelope.

The table or glate G and frame or lever F are preferably made in separate pieces, as S5 shown. j

The frame B is furnished with a stop Ui to limit the downward movement of the pivoted frame F.

I claim-- 9o l. The combination, with a gage, of a stationary shear, a pivoted en velope-supporting plate, and a movable shear secured at the end of said plate, substantially as specified.

2. The combination,with a gage K, of a sta-4 95 tionary shear C, pivoted frame F, inclined envelope-supporting plate G, secured to said frame F, and movable shear D, secured to said pivoted frame F, substantially as specified.
