To all whom it may concern:

Be it known that I, HENRY D. TAYLOR, of

Rochester, in the county of Monroe and State of New York, have invented anew and useful Improvement in Machines for Open ing Envelope, which improvement is fully set forth in the following specification, and shown in the accompanying drawings.

The present invention relates to machines for opening envelopsand an object of this invention is to provide an improved construction in which the envelops are fed forwardly along and laterally toward a guide which directs the envelops to a suitable cutting mechanism.

To this and other ends the invention con sists in certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims. V

In the drawings: Figure l'is a front View of a machine embodying the present im: provements; Fig. 2 is a section on the line aa, Fig. 1; Fig. 3 is a section on the line 6-6, Fig. 1, through the feeding and defleeting roller and the supporting cap Fig. 4.- is a section on the line c0, Fig. 1, through the feed roller which is located in proximity to the cutting mechanism; Fig.

" 5 is a vertical section through the machine on the line cZcZ, Fig. 1; Figs. 6, 7 and 8 are detail views of the guide; Fig. 9 is a top view of the machine in proximity to the feeding and deflecting mechanism, Fig. is a view in elevation of the parts arranged within the inclosing casing"; and Fig. 11 is a view in plan of the parts shown in Fig. 10.

Referring more particularly to the drawings, 1 indicates the base on which may be arranged a motor 2 of any suitable type. In this instance, the motor is electric and is supplied by a current through the line wires 3 and is controlled by a rotary snap switch a which does not form the subject'matter of the present invention. There is also provided Jreferabl on the base 1 a cuttin mechanism which may'embody two rotary cutters 5 and 6, the latter being'a'rranged above the former. I

The cutter 5 is of peculiar formation, one side thereof being flat throughout its entire surface while the other side has a central flattened portion, a cone-shaped portion surrounding said flattened portion and a'bev-" eled edge the flat side of which cooperates speed of the cutter 5.

with the flattened face of the cutter 5 so that the cuttings are deflected downwardly by the cutter 6into a chute 16 which is carried by the casing 17 inclosing the motor and other operative parts of the machine.

The cutter 5 is carried by a shaft 7 turnmg m a frame 8 on the base 1, said shaft having a large drive wheel or pulley 9 at its rear end about which passes a belt 10 which also passes about a pulley 11 on the shaft 12 of the motor 2, the size of the pulleys 9 and 10 being such that the speed of the shaft 7 is less. than that of the motor shaft 12. Drivlng connection between the shaft 7 and a shaft 13, on which the cutter 6 is arranged,

arranged respectively on the shafts 7 and 13, the gear 14 being greater in diameter than the gear 15 so that the peripheral speed of the cutter 6 is greater than the peripheral The shaft 13 is mounted to turn on the frame 8 above the shaft 7.

0n the casing of the machine there may be supported a table 18 which has an upwardlyextending guide flange 19 projecting from the inner edge thereof, said flange serving to direct the envelopsto the cutting knives and preferably havinga groove 20, the upper and lower walls of which converge toward a recess 21 in which the cutters 5 and 6 operate, the guide beingprovided with a grooved'portion 22 beyond the recessto still further guide the envelope after they have been opened by the cutting mechanism.

While the en'velops are traveling in the groove 20, they are snbjectedto a slight pressure on opposite sides and inproximity to the portions in the groove for a purpose which will be-more fully described hereinafter. These pressure devices may embody two pivoted arms 23 and 24, one co,- operating with the upper surface of they envelop and the other cooperating with the lower surface of the envelop. The arm is pivoted at its forward end at, 25 to the guide flange 19 and is guided on apin 26 at its rear or freeend, a spring'81 operating on the arm 23 to yieldingly press the said arm downwardly. The arm 2% is pivoted at 27 at its forward end to a hrac :et 28 arranged cn the under, side of the table 18 and extends upwardly through a slot 29 in the table, a spring 30 being interposed bewill deflect the envelops laterally with force againstthe guide, the following is'provided: A feeding member operates through the table 18 and preferably embodies an endless belt 32 made of rubber and substantially T-shaped in cross section in order that it may be properly held to'its two grooved pulleys 33 and 34. The pulley 33 may be securedto the shaft 7 by a bolt 35 which also secures the knife 5 to the shaft 7, whereas the pulley 34 is journaled on the bracket 36 projectingupwardly from the base 1. With this arrangement, the belt or feed member 32 operates from a point in advance of the cutting mechanism and cooperates with the envelop from such point up to and beyond the cutting'point of the cutting mechanism. The speed of this belt is the same as that of the lower cutter 5 of the cutting mechanism and is less than that of the upper cutter 6 so that the upper cutter produces a shearing action on the edges of the envelops in connection with the lower cutter 5.

' Cooperating with the feed member 32 which engages one side of the envelop is a deflecting member 37 which is in the form a of a wheel or rollermade of rubber or other suitable yielding material and having a mushroom shape whereby when it engages an envelop, its periphery will yield laterally and shift the envelop laterally to the; guide flange 19. This rubber roller has a metallic center 38 whichis ournaled on a stub shaft 39 the latter being carried by a slide tOmovthat face opposite the face which is engaged by the feeding member 32. After the en velop has been deflected by the deflecting member 37, it is carried by the belt and said deflecting roller 37 to a roller43 which 0p- .erates substantially in a vertical plane with the cutting point of the cutting mechanism sothat the tendencyof the cutters to shift the envelops away from them isovercome and the envelops are held firmly, between moving in the same direction.

the roller 13 and the feeding member 32 during the cutting action. The roller 43 may have a yielding or resilient periphery 44 made, in this instance, of rubber of T shape in cross section and the said roller -13 turns upon a journal 45 rigidly carried by a slide 4.6 which is guided on vertical ways on the cap 4-1 before mentioned.

In order that both of the rollers 37 and L3 will be held with yielding pressure toward the feed belt 32, a spring is provided in the form of two yielding arms &7 and 18 secured centrally by a fastening 49 and having their free ends looped at 50 and then fitted in openings 51 in the slides 410 and 46.

In the operation of the machine, the rotary snap switch l is shifted by the controller 4 to start the motor 2 which drives the cutters 5 and 6 so that their meeting edges move in the direction of the line of feed through the machine and the belt or feed member 32 has its effective portion As both of the rollers 37 and 4-3 contact with this belt when no envelops are being operated upon,

' both of these rollers will be driven by such contact. Upon the introduction of an envelop at the meeting point between the roller 37 and the belt 32, the envelop is grasped between these two elements and carried for wardly. The upper or deflecting roller 37 moves upwardly with its slide 40 to correspond to the thickness of the envelop and, at the same time, its periphery yields or shifts laterally thereby causing a like movement of the envelop toward the guide flange 19. This deflection of the envelop is of sufficient force to press the edge of the envelop against the guide and, at the same ti1ne',.to cause the envelop to slip on its contents and bulge slightly. The edge of the envelop then enters into the tapering groove 20 and is pressed on opposite sides by the fingers or arms 23 and 24 which act on this bulged portion in such a manner that the envelop is spread or expands into the groove 20 which will not take the contents, thereby permitting the cutters to act upon the envelop without cutting the contents. The

arrangement of the cutters is such that the shaving or clipping is carried downwardly into the chute 16 by the cutter 6, and the envelop is held against lateral deflection by the cutters by reason of the fact that it is engaged on opposite sides by the belt 32 and the roller &3 in proximity to the cutting point. After the envelop is trimmed, it is discharged at one end of the table by the momentum produced by the feeding mechanism.

A machine for opening envelops constructed in accordance with this invention positively moves the envelops to the cutting mechanism and also positively forces the envelops laterally toward the guide. The device for deflecting the envelops laterally is so mounted that it does not produce any wearing action on the feeding belt but at all times moves in a plane with said belt. It is thus possible to obtain a longer life in the machine and there are not so many parts liable to get out of order, the roller being rigidly mounted upon a slide mounted firmly above the table.

What I claim as my invention and desire to secure by Letters Patent is:
