- FIG. 4 is a left side elevation similar to FIG. 2 but with the door in the open position;
- FIG. 5 is an enlarged partial view of the key brushing mechanism
- FIG. 6 is a view similar to FIG. 5 but with the brush in an extended position
- FIG. 7 is an enlarged sectional view on line 77 of FIG. 2 and showing the front view of a cam and follower;
- FIG. 8 is a top view of FIG. 7;
- FIG. 9 is an end view of FIG. 7.
- the figures of the drawing show a key cutting machine I] designed to use a master key 12 as a pattern for cutting a key blank 13 in conformity therewith.
- the machine ll includes a base 14 on which the parts are mounted and in this machine there is provided a master key vise l6 and a blank key vise 17 for holding the master key 12 and key blank 13, respectively.
- a stylus I8 is provided to cooperate with and feel the contours of the master key 12 and a key cutter, shown as a rotating type key cutter 19, is provided to cooperate with and cut contours on the blank key 13.
- a carriage 21 is provided on the machine II with this carriage being movable on the base 14.
- Means is provided including this carriage 21 to establish relative longitudinal and lateral movement between the key cutter l9 and the blank key 13in accordance with relative longitudinal and lateral movement, respectively, between the stylus l8 and the master key 12.
- the carriage 21 is pivotally mounted on a carriage shaft 22 and this pivotal movement of the carriage 2] establishes the aforementioned relative lateral movement because the stylus l8 and the cutter 19 are mounted on the carriage 21.
- the key vises l6 and 17 are mounted fixedly on the base 14. Accordingly, the aforementioned relative longitudinal movement is provided by longitudinal movement of the carriage 21 along this carriage shaft 22. This provides movement of the key cutter 19 in accordance with longitudinal movement of the stylus 18.
- the vises l6 and 17 may be actuated in any suitable manner and as shown in the drawing the vises are actuable by manual handle 23 to clamp the keys in the respective vises.
- the clamp handle 23 is shown in the clamped position.
- the carriage 21 carries a cutter shalt 26 journalled for rotation therein parallel to the carriage shaft 22.
- the rotatable key cutter 19 is directly fixed to this cutter shaft 26 for rotation therewith as is a belt pulley 27.
- a cutter motor 28 is fixedly mounted on the rear of the base 14 and has a shaft 30 parallel to the carriage shaft 22.
- This shaft 30 has a belt pulley 31 and a belt 32 interconnects the pulleys 27 and 31 to drive the cutter shaft 26.
- a drive motor 29 driving through gear reduction mechanism 35 is provided for establishing motive means for reciprocating the carriage 21.
- This motor 29 and gear reduction mechanism 35 are mounted on the rear of the carriage 2 l to help counterbalance the carriage so that only a small force of about one pound is applied on the stylus l8 bearing against the master key 12. This same force will be present on the cutter 19 against the blank key 13.
- a first and a second drive means is provided from the motor 29 to the carriage 21.
- the first drive means is a yielding drive means and the second drive means is a positive drive means.
- the gear reduction mechanism 35 rotates a cam 36, better shown in FIGS. 7 and 8.
- This cam 36 cooperates with first and second cam followers 37 and 38, respectively.
- Springs 39 engage these cam followers 37 and 38 and urge the cam followers into generally diametrically opposed contact with the cam 36.
- Both cam followers 37 and 38 have a longitudinal aperture 40 received on the carriage shaft 22 to be pivotable thereon and to pivot with movements of the carriage 21.
- cam follower 38 is held by snap rings 41 in a fixed longitudinal position on the carriage shaft 22 whereas cam follower 37 may longitudinally move on the carriage shaft 22 as yieldingly urged against the cam 36 by the springs 39 and dependent upon the particular diametral dimension of the cam 36 for that rotational position of the cam. It is the springs 39 which provide the first yielding drive means for reciprocating the carriage 21 in a first longitudinal direction.
- the longitudinally fixed position of the cam follower 38 is that which establishes the second positive drive means for the carriage in the opposite longitudinal direction.
- FIG. 7 illustrates the position of the cam 36 before the cutting of the key blank 13 by movement of the carriage 21 to the left as viewed in FIG. 1.
- the motor 29 rotates the cam 36 through the gear reduction mechanism 35, this cam 36 rotates clockwise, as seen in FIG. 7. This tends to move the cam follower 37 to the right which is resisted by the urging of the springs 39.
- the result is that the carriage 21, on which the cam 36 is rotatably mounted, is moved to the left so that the cam 36 always tends to remain in engagement with the cam follower 38.
- This engagement is continuous unless some unexpected large force must be overcome.
- An example of this might be an improper mounting of the master key 12 in the master key vise 16 so that the stylus 18 engaged some right angle shoulder.
- Another example might be an exceptionally dull cutter 19 such that the cutter 19 ran up against a substantially right angle shoulder which it was unable to cut and this would develop a large force restraining the longitudinal movement of the carriage 21 in the first or leftward movement thereof.
- the springs 39 will establish a yielding first drive means to longitudinally reciprocate the carriage 21 to the lefi in a key cutting direction.
- the radial dimension of the cam 36 between the high and low points thereon is sufficient to provide a key cutting travel of the carriage 21.
- FIG. 1 shows the belt 32 as being laterally shifted to the right on the cutter shaft 26 and the lateral flexing of the belt 32 permits this longitudinal movement of the carriage 21 while still providing rotative drive to the cutter 19.
- a brush mechanism 45 is provided to brush away any burr on the cut key 13.
- This brush mechanism 45 is provided, of course, only for the key blank 13, not the master key 12, and is designed to come into use only during the reciprocation of the carriage 21 to the right as viewed in FIG. 1. This will be during the time when the second positive drive means is actuating the carriage 21.
- FIG. 6 shows this brush mechanism 45 in the extended position whereat a brush 46 is in engagement with the cut key 13.
- the brush mechanism 45 includes generally a first arm 48 and a second arm 49 interconnected at a pivot 50.
- the first arm 49 is pivotally journalled on the carriage shaft 22 and connected for longitudinal reciprocation on the carriage shaft with the carriage 21.
- a tension spring 51 engages hooks on the arms 48 and 49 tending to urge these arms into a straight position shown in FIG. 6. This urges the brush 46 to the extended position as shown in this figure.
- An eccentric cam 53 is fixedly mounted on the cutter shaft 26 for rotation therewith and cooperates with a cam follower 54 fixed on the outer end of the second brush arm 49. The rotation of this eccentric 53 thus causes up and down arcuate movement about shaft 22 of the brush 46 transverse to and in engagement with the cut key 13 to break ofi' any burr on this cut key.
- a longitudinal groove 56 is provided in the right end of the carriage shaft 22 and is shown in FIG. 3.
- This longitudinal groove has an exit ramp 57 merging smoothly with the circumference of the shaft 22 at a location remote from the right end of this shaft 22.
- the longitudinal groove 56 has a right angle shoulder 58 substantially along a radius from the axis of this shaft.
- An elastic finger 59 molded as a part of the journal bearing on the first brush arm 48 elastically engages this right angle shoulder 58 as best shown in FIG. 5.
- the finger 59 is elastically urged toward the axis of the shaft 22 by the natural resiliency of the material of the first brush arm 48.
- FIG. 2 shows a transparent door 61 in a closed position helping to cover the key cutting machine 11 and FIG.
- FIG. 4 shows this door 61 is in an open position.
- the carriage 21 is raised to an inoperative position and FIG. 5 shows this first brush arm 48 as also raised with the carriage 21.
- the elastic finger 59 will enter the longitudinal groove 56 so that the end of the finger may engage the right angle shoulder 58.
- This cocks the brush mechanism 45.
- the lowering of the cutter shaft 26 Upon subsequent lowering of the door 61 and lowering of the carriage 21, the lowering of the cutter shaft 26 then bends the brush arm 49 relative to the first brush arm 48 and stresses the tension spring 51.
- the brush mechanism 45 is then in the position shown in FIG. 5 where it is cocked, ready for use, but the brush 46 is to the rear out of engagement with the key blank 13.
- the brush mechanism 45 remains in this cocked out-of-the-way position during the first drive means which drives the carriage to the left as shown in FIG. 1.
- the elastic finger 59 will move up the exit ramp 57 of the longitudinal groove 56 and when the end of the finger 59 no longer engages the right angle shoulder 58, there is nothing resisting the extension force of the spring 51. Accordingly, the brush mechanism 45 will be triggered and be extended to the position shown in FIG. 6. In this extended position the brush 46 engages the cut key 13.
- the cutter shaft 26 will be rotating at this time of driving the carriage 21 to the right as shown in FIG. 1, and accordingly the cam 53 will reciprocate the brush 46 up and down to debur any burr remaining on this cut key 13.
- the key cutting machine 11 has a cover 62 to help protect the machine from dirt and also to protect personnel near the machine from being injured in die moving mechanism.
- the door 61 cooperates with the cover 62 to enclose the machine 11. As stated above the door 61 may be raised to an open position to amount and remove the keys 12 and 13.
- the door 61 is pivoted on a door pivot 63 and may be pivoted about 60 between a closed position shown in FIG. 2 to an open position shown in FIG. 4.
- a slot 64 is fastened on the inside of one side of the door 61 and cooperates with a pivot pin 65 fixedly carried on the outer end of a spring arm 66.
- This spring arm is pivotally journalled on the carriage shah 22 and carries a fixed pin 67 on the rear end thereof cooperating with some lost motion with a semi-circular groove 68 on the rear of the carriage 21. Accordingly, as the door is swung upwardly to an open position by being swung through an arc of about 60. the pin 65 also moves upwardly trough an arc of about 60and this swings the carriage 21 upwardly through an arc of about 55.
- UIOS 1t accordingly is in an inoperative position away from the keys 12 and 13 so that they may be removed and new keys placed in the vises 16 and 17.
- the arm 66 is a spring arm so that a service man may take hold of a handle 69 on the front end of this arm 66 and spring the pivot pin 65 out of the slot 64. This will permit how to lower the can'iage 21 into operative position even with the door 61 open so that necessary servicing of the machine may take place.
- a switch 72 is fixed on the base 14 and is controlled by the closing of the door 61. This switch is connected in circuit with the cutter motor 28 so that should the door 61 be opened during operation of the machine, this will de-energize the cutter motor 28 and stop rotation of the cutter 19. This is a safety factor.
- the drive motor 29 is not deenergized by actuation of this switch 72 and this is to make sure that the carriage 21 will complete its cycle of movement and return to the initial position as shown in FIG. 1.
- the axis of the cutter shaft 26 lies slightly below the plan established by the carriage shaft 22 and motor shaft 30. This establishes that tension on the belt 32 helps to hold the forward edge of the carriage 21 downwardly so that the stylus 18 cooperates with the master key 12 and the cutter l9 cooperates with the key blank 13. Additionally, the direction of rotation of the cutter 19 is clockwise as shown in FIG. 2 and this means that rotation of the belt 32 is downwardly over the outer edge of the belt pulley 27 on the cutter shaft 26. This also aids in holding the stylus 18 down against the master key 12.
- a fixed shaft 76 is fixed on the base 14 approximately directly below the cutter shaft 22.
- This fixed shaft has a relieved portion 77 where a part of the circumference of the shaft is cut away. Smooth entrance and exit ramps are prov ided on each end of the relieved portion in order to smoothly merge with the circumference of this shaft 76.
- the relieved portion extends for a distance slightly less than the distance of travel of a carriage 21, and does not quite extend to the initial position of the carriage 21 of FIG. 1.
- a depending boss 78 is fixed on the downward edge of the carriage 21 and carries an adjusting screw 79. The inner end of this screw 79 cooperates with either the circumference of the fixed shaft 76, or the relieved portion 77, depending upon the position of the carriage 21.
- the above description and drawing disclose a key cutting machine which is well adapted for semi-automatic operation by relatively unskilled personnel and by many different people, so that just one person alone need not be the operator of the machine.
- the machine is rugged and does not get out of adjustment easily, therefore, also helping to permit operation by a number of different people.
- the door 61 is closed when the machine is in operation and this makes the machine safe for operation out near the public because they cannot be injured by the moving parts of the machine since the machine will stop the cutter 19 when the door 61 is raised. All one needs to do is clamp the master key 12 and the blank key 13 in the vises, close the door and turn on the machine and it will automatically cut a key in accordance with the master key 12.
- the first drive means is a yielding drive means which achieves safety in the longitudinal reciprocation of the carriage 21 in the cutting direction. Should any unforeseen obstacles be placed in the way of carriage 21, either through the instrumentality of the stylus 18 or cutter 19 or any other obstacle. the springs 39 will extend and the carriage 21 will not continue its cutting movement until the obstacle is overcome. If it is merely some difficult place to cut on the key blank 13, the springs 39 may extend slightly but later the carriage 21 may catch up to have the cam again contacting the cam follower 38. This is a safety factor to avoid damage to the machine or also to avoid injury to personnel.
- the brush mechanism 45 comes into play only during the return movement of the carriage 21 to move any burr on the cut key 13 so that the key is ready for any use without further hand deburring operations. At the end of the cutting operation, the door 61 may be raised, the manual handles 23 raised and the master key 12 and cut key removed from the machine. The machine is then ready for the next keycutting cycle of operation.
- a key cutting machine comprising in combination,
- means including said carriage establishing relative longitudinal and lateral movement between said key cutter and blank key vise in accordance with relative longitudinal and lateral movement, respectively, between said stylus and master key vise,
- first yielding drive means from said motor means to said carriage for said relative longitudinal movement in a first direction

- first and second arms interconnected at an arm pivot
- said first arm pivotally journalled on said carriage shaft and connected for longitudinal reciprocation thereon with said carriage
- a cam follower on the outer end of said second brush arm cooperating with said eccentric cam to cause up and down arcuate movement of said brush transverse to and in engagement with said out key during the return movement of said carriage to thus break off any burr on said cut key.
- said carriage being pivotally raisable to an inoperable posi tion for key changing
- a key cutting machine as set forth in claim 21 including means to continue operation of said first and second drive means despite stopping of said key cutter.
