Myinvention relates broadly to improvements in envelope openers and paper cutters, and more particularly to combined envelope openers and paper cutters and paper punches.

It is one of the principal objects of my invention to provide a relatively compact and small device which may be carried in the pocket or handily used about a desk, and which has combined and cooperating structure designed to open envelopes, cut or trim paper, punch holes in paper and the like, and which in addition has means for guiding and determining the point at which an envelope or paper is to be cut.

Another object of my invention is to provide a very simple and effective operating mechanism, and to provide means whereby proper adjustment between the rotary cutting blades is obtained to afford a clean, sharp cut. Furthermore, there are no fragile parts likely to become deranged or to get out of order or broken, and the device can be manufactured and sold at a price recommending its use as an economical desk and pocket implement.

Other and equally important objects and advantages will be apparent from the detailed description taken in connection with the accompanying drawing, however, a broad interpretation of my inventive concept is not to be assumed from the particularization required to impart a clear understanding of the construction, operation, and advantages of my invention.

In the drawing wherein I have illustrated a In the drawing wherein like characters of reference are used to designate like or similar parts throughout the several views:

The numeral l designates the casing or supporting frame of my device which has an elongated base 2 with side and end walls and in which is pivotally mounted as at 3 a hand operating lever 4, adjoining and communicating with the base is a compartment 5 having side and end walls in which is journaled the shaft 6, shaft 6 is mounted for both rotational and sliding movement and carries at its end a. rotary cutting wheel, or rotary blade I, the rotary cutter 1 may be rotationally mounted on the shaftir desired, rather than mounting the shaft itself for rotation and keying the blade to it. Mounted on a stub shaft 6A is another rotary cutting! wheel, or rotary blade 8; the proximity of the two blades being such that when they are positioned adjoining and in proper contact with each other, a sharp, clean cut will be made through an envelope or other sheet of material drawn between them.

livotally mounted as at 9 in the frame is a lever l0 having an arm H pivotally connected to the operating 1ever 4 and connected with the shaft 6 so that pressure on the operating lever 4 causes the shaft to slide or move horizontally. The normal position of shaft 6 is shown in Figures 1 and 4 with the rotary cutters I and 8 spaced from each other. The shaft is held in this position by a coil spring 12. Pressure on the operating lever moves the shaft against the force of spring 12 to bring the rotary cutters toward each other and into engagement to make a sharp clean cut through an envelope or sheet of material drawn therebetween.

It will be noted that as the shaft 6 is moved longitudinally, its free end passes out through the end wall of the base. A keeper I3 with a right-angular guard I4 is provided so that the end of the shaft functions as a paper punchthere being an opening I5 in the guard for that purpose. The shaft 6 therefor serves the dual purposes of rotary cutter support and paper punch.

Mounted in the space l6 between the walls of" base 2 and compartment 5 is a guide piece H to determine at what point an envelope or sheet of material is to be cut. An adjusting nut 18 fixes the position of the guide and is provided with the usual spring tensioning device Hi.

Pressure on the operating lever 4 and consequent movement is translated into sliding movement of the shaft 5 through lever I0 against the force of spring 2, so that holes may be punched in sheets of paper by the end of the shaft. The same operations move the shaft at other times to bring the rotary cutters I and 8 together with the proper pressure to cleanly and sharply cut through an envelope or sheet of material drawn through the cutters.

While it is believed that the operation, construction, and advantages of my invention will be fully apparent from the foregoing, it is pointed out that changes in form, size, shape, arrangement and coordination of parts may be made,

provided such changes fall within the purview of what is claimed.

I claim:

1. A combined envelope opener, paper cutter and punch, comprising a frame, a slidably mounted shaft carried by the frame, means for actuating the shaft to force an end of the shaft through a sheet or sheets of material to form a punched hole therein, a rotary cutter carried-onthe other end of theshafft zalsecond rotary-cutter coop: erating with the first cutter to open an envelope passed therebetween, the position of the first cuteter with respect to the second heing determinable v by the position of the shaft, and an adjustable.

guide for regulating the point at which an en velope or sheet of material is cut 1 j 2. A cutting and punching device comprisinga.

-;nected to said shaft and an operating lever, which is pivotally connected to said frame, a spring connect ed" tosaid lever to retain said actuated means in inoperative position, a fixed rotary cutter coeparating with. said first rotary cutter, and said frame, and a pair of rotary cutters; 'meansfor**" regulating the position of one cutter withgrespect to theother cutter, and at the same time regu lating the pressure between 'the cutters including Eslidahle shaft on which one cutter is -mounte'df,

first rotary cutter being movable with respect to the fixed cutter upon movement of the shaft to adjust the proximity of the cutters to perform a clean sharp cut.
