Application flied July 2, 1918. Serial No. 776,918.
T all whom it may concern Be it known that I, Ermuam J. Soon, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Machines for- Opening Envelops, of which the following is a speci cation.
This invention relates to machines for opening envelops and has for its object to provide a machine of this character which is provided with a pair of rotary cutters, and means for feeding envelops to said cutters whereby a small portion of the edge of the envelop is removed to expose its contents.
A further object of the invention is to provide a pair of feed rolls and a pair of independent guide rolls the latter being located approximately opposite the cutters for engaging, feeding and guiding the envelop while it is being operated upon by said cutters.
A further object of the invention is to set one roll of each pair at an angle to the axis of its mate whereby the envelop is held lirmly in position against its guide while being operated upon by the cutter.
The invention further consists in pro viding a table with a guide flange, and means for a liusting said tableand flange longitudinally to regulate the amount that shall be cut from the edge of the envelop.
With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.
Figure l is a perspective view illustrating my improved letter opener coupled to, to be driven by an electric motor. Fig. 2is a front elevation of the machine with the easing partly broken away and in section to better illustrate the operating mechanism. Fig. 3is a detail illustrating one of the guide rolls mounted on the pivotally hung gear casing. Fig. 4-is a plan view showing a portion of the casing in section to better illu trate the mechanism. Fig. 5--is a sectional elevation from the left end of the machine showing the relation of the cutters and guide rolls. Fig. 6is a perspective view of the table in detail. Fig. 7-is a detail illustrating one of the feed rolls as mounted on a pivoted arm.
Referring to the drawings, 10 designates while being operated upon by upon the base p'ortion 12.
A table 13 is arranged to extend across the front of the casing, the same being provided with arms 14 and 15. The arm 14 is preferably rigidly secured to the side of the casing by screws 16-16 while the arm is retained in the desired position by means of screws 17 which pass through longitudinal slots 18 in said arm.
A cam 19 is supported in position on the pivot screw 20 to engage said arm and is provided with a lever 21 having a handle 22 whereby when it is desired to move the table in or out, that is from or toward the cutters, it is only necessary to turn, or swing the handle from one position to another for the purpose hereinafter described. The in ner edge of this table is turned upward, as at 23, see Figs. 4 and 6, roviding a flange which serves as a guide r the envelops in being carried across the table and acted upon by the knives.
A pair of complemental conical cutters 24 and 25 are arranged to meet and overlap each other through the opening 33 in the table, and are mounted on shafts 26 and 27 in bearings 26 and 27 respectively, and driven by the intermeshing gears 28 and 29 through the pinion 30 and shaft 31 by the motor 32.
A lower feed roll 34 is mounted on the shaft 35 supported in the fixed bearing 35 on the arm 44 and is driven from the shaft 27 by the pulleys 36 and 37 and belt 38. An upper feed roll 39 is mounted on the arm 40 and is pivoted at 41 to the bearing support 42, see Fig. 5. An aperture 52 in the table permits the roll 34 to contact with the envelops when fed thereover. This upper feed roll has an axis set on an angle to that of its mate or complemental roll below and is mounted to rotate freely on the pivot screw 43. A tension is applied to this roll by spring so as to bite the envelop between it and the driver 34 to feed the same.
It is found in practice that a single set of rolls is not suflicient to feed and guide the envelops accurately through the machine the cutters, therefore I have provided another set of and fixed to rolls which serve, in addition to assisting the envelops, to also guide the same and hold them accurately in position while being operated upon so that a cut of a uniform width will be taken. The lower or driving roll 46 of this set is. mounted on the end of the cutter shaft 27 and the upper roll 47 of this pair is loosely mounted on the .screw 48 which is threaded into the hub 49 on the casing 50, which is designed to cover and protect the upper cutter 2-1. This casing is pivotally connected to the frame on the screw 51 whereby the same with its roll may raise or lower and accommodate itself to envelops of different thicknesses. The axis of this upper roll, like that of roll 39, is set on an angle to its complemental roll or mate, whereby the envelop is carried backward or inward and held against the guide while passing through the machine. The 0 ening 33 in the table is large enough so that in addition to permitting the cutters to meet therethrough the periphery of the roll 46 may extend therethi'ough to engage the underside of the enve op.
In the operation of my improved machine the envelops a to be opened are placed in a pile on the left end of the table 13 where by a simple movement of the hand of the operator they are advanced and engaged by the feed rolls 34 and 39 and fed forward to be acted upon by the cutters which remove a very small portion or strip of the folded edge of the envelop but not enough to possibly cut into the contents thereof.
It is found in practice that with a single set of feed rolls the cut taken through the envelop is apt to be uneven or not uniform, that is, the forward portion of the envelop has a tendency to work outward and in some cases prevent the cutters from cutting the envelop. To obviate this difliculty I have mounted an auxiliary set of rolls opposite the cutters which rolls serve to hold the envelops firmly back against the guide while passing through the machine.
The table on which the envelops rest is supported on arms 14 and 15 which are more or less resilient or yieldable and when it is desired to obtain a deeper cut or to cut more from the edge of the envelop, the lever 17 is thrown over backward or to the rear of the machine whereby its cam-shaped hub carries the arm 15, and consequently the guide flange 23, backward and causes the arm 14 to spring slightly, thus permitting a wider edge on the envelop to be presented to the cutters. claim:
1. In an envelop opening machine, a sup porting table, a air of rotary cutters, a pair of envelop fgeding and guiding rolls mounted substantially opposite said cutters to support the work while being acted upon thereby, and means for rotating said cutters and rolls. A
2. In an envelop opening machine, a su porting table, a 'pair of rotary cutters, I of envelop feeding and guiding rolls mounted substantially opposite said cutters, to support the work while being acted upon thereby the axis of one of said rolls being set on an angle to that of the other of the pair and means for driving both cutters and one of said rolls.
3. In a machine for opening envelops, a pair of rotary cutters, a set of feed rolls, mounted substantially opposite said cutter, a set of guide rolls, the axis of one of each of said sets of rolls being set on an angle to that of its mate, means for driving both set, and a table over which the envelops to be opened are fed by said rolls.
n a machine for opening envelops, a pair of rotary cutters, a set of feed rolls, mounted substantially opposite said cutters, a set of guide rolls, the axis of one of each being set on an angle to for driving both of said rolls in each set,'a table over which the envelops to be opened are fed by said rolls, and means whereby one roll of each set is adjustable to feed letters of different thicknesses. v
5. In a machine for opening envelops, a pair of driven rotary cutters, a pair of feed rolls, mounted substantially opposite said cutters, a pair of independent guide rolls, means for driving one roll of each set, the axis of one of said rolls being set on an angle, a table for supporting the envelops while being cut, a guide flange on said table back of said cutters, and means for adjusting said table and guide to regulate the amount to be cut.
In testimony whereof I aflix my signature in presence of two witnesses.
