0. E. GAMPBELL. MACHINE FOR GLIPPING ENVELOPS.

APPLICATION FILED DBO 4 1908 tion to disclose the inrans employed to force vt'ull clear, and exact description of the same,

.hands free to feed and remove the letters on which the envelop to be clipped is placed.

CHARLES E. CAMPBELL, OF DETROIT, MICHIGAN.

MACHINE FOR CLIPPING ENVELOPS.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed December 4, 1908. Serial No. 465,934.

To all whom it may concern:

lie it known that 1, CHARLES E. CAMP- ncnr, citizen of the United States, residing at Detroit, county of Nayne, State of Michigan, have invented a certain new and useful Improvement in Machines for Clipping En velops, and declare the following to be a such as will enable others skilled in the art to which it. pertains to make and use the same, reference being had to the accompanying drawings which form a part of this specification.

My invention relates to an improvement in a machine for opening cnvelops, shown in the accompanying drawings and more fully disclosed in the following specification and claims.

The object of this invention is to supply a machine which will rapidly cut the end of scaled envelops without dange-r'of damaging the inclosures.

()no purpose of the invention is to provide a. platt't'n'tn for supporting the envelop and a guide for feeding it to the cutting knife in order to further insure against damaging the contents of the envelop often resulting from carelessly clipping the end of an envelop.

A further improvement consists in means whereby the device may be operated by hand,-or by foot movement leaving the from the cutting device.

In tllG (lIfl'\\ 'l11gS2 Figure l is a perspective view looking at the device from the platform side of the machine. Fig. is an end elevation with parts broken away and in sec the swinging blade into shearing contact with the stationary blade. Fig. 3 shows the device operated by foot power. Fig. 4 is a perspective view disclosing more clearly the chamber into which the clipped ends of the envelop drop.

Referring to the letters of reference indicated on the drawings: is a platform "lhe platform A is supported by suitab e logs A and is provided with an upstanding flange or guide A against which the envelop i is forced in order to insure its end being (X- actly parallel with the cutter blade.

Below and beyond the end of the platform and preferably integral therewith, is a suitable pocket or chamber A to receive the rearwardly; from the platform and also inf lcgral with the wall of the pocket A is an arm A to whicli a cutter blade is pivoted.

ll is a swinging arm pivoted at a to the meu'ther it. Secured to the upper portion of the swinging arm is a cutter blade B adapted to serve in conjunction with a fixed blade (1, attached to the wall of the pocket A. its edge flush with the top of the plat- :t'ortndtl5 is a knob mounted upon the upper edge of the swinging arm by means of which the arm may be operated.

Rising from the wall of the pocket A is til) a short post A serving as an abutment for the spring actuated plunger 7) housed Within the tubular stem B, which latter projects rcarwardly from the swinging arm l5.

Sleeved on the pivot of the swinging arm and bearing against the head of the pivot pin a is a spring B whichmay he U-shap'cd and held between the lugs a, a as shown or may be of other suitable form, such as a coiled. spring sleeved on the pivot; pin. As will be readily nndt-n'stood, the purpose of both the spring actuated plunger 0 bearing against'the post A, and the spring 15* supported on the pivot and bearing against the swinging arm is to force the cutter blade of the swinging arm into shearing relation with the stationary cutter blade. .It will also be seen that the swinging arm projects rearwardly a relatively long distance from the pivot u. and that the supporting arm A also projects rearwardly an equally long dis-' lance, the ends of each abutting and formed :t1(' lltt]) .tl, the purpose being to assist the springs in imtiutain'ing the blades in a cutting relation throughout the entire stroke oi tllc swinging blade.

I) is a. coiled spring one end of which is supported on a lug formed on the wall of the pocket A". the other engages the underside of the swinging bar B to return it to its initial position after being tu-tuated.

1C is a rubber butter or cushion supported in a suitable S()('l\'tl 'l'orincd in the wall of the pocket-A-- and. is designed to receive the impact of the blow rcstilting from the opera tion of the swinging arm. I) is a lug formed near the lower edge oi" the swinging arm to encounter the butler I. when the arm B is operated.

In Fig. l have shown hovthe device may be operated by foot power.

lOt)

tures provided in the bottom wall of the pocket A.

H is a bar cast integral with the swinging arm or otherwise secured thereto as desired. I is a foot pedal and I a pitman connectingIthe pedal and bar H.

aving indicated the sevaral parts by ref-' ed to pass the platform in shearing relation with said fixed blade whereby the envelop may be clipped and the clipping deposited in the pocket.

erence letters, the operation will be readily f forms a wall, a blade fixed against said deunderstood.

The envelop to be cut is laid upon the latforin A and against the guide A forcing it into contact with the lower portion of the swinging arm B, it being noted that the cuti ter blade B proper is above the edge of the platform when the swinging arm is in its initial position. Theswinging bar is then actuated by striking the knob B which op erating clips off the end of the envelop depositing the clipping into the pocket A Upon referring to Fig. 2 it will be noted that the swinging arm is slightly'beveled in cross section on the side adjacent to the platform commencing at. a point directly below the cutting edge of the-blade secured to the swinging arm and slanlii-igaway from the platform. The object of this is to provide room for the clipped end of the envelop and to assist in conveying it downwardly into the pocket A.

I Havingthus describedmy invention, what J cllaim is In a machine for chppmg envelops, a

' platform to support the envelope and-provided on one side with a guide, a pocket formed with the platform and depending therefrom atone end thereof, said pocket receiving the clippings, a. swinging cutter blade adapted to pass the edge of the platform in shearing relation therewith and immediately above said pocket, whereby the end of an envelop may be clipped and the clipping deposited in the pocket.
